Description

The present invention relates to a medical device equipped with a sealing cover for local surgery that prevents smoke, odors, and particles generated when a medical device performs a surgical procedure on a living body.

In conventional medical devices, when performing a treatment to remove moles, warts, etc., the skin and the like are evaporated and smoke, odor, and particles are generated. Normally, these fumes, odors, and gases containing particles are diffused into the treatment room and are exhausted by an air conditioner or a vacuum device installed near the practitioner or patient. Depending on the capacity of the air conditioner and the location of the vacuum device, smoke and odors could remain in the treatment room for a long time. The smell of smoke is also unpleasant, and the smoke and particles are mixed with substances that are harmful to the body, putting a burden on the body of the practitioner and patient.
Furthermore, depending on the layout of the hospital, it may be difficult to install a vacuum device near the practitioner or patient, which may interfere with the treatment.

As an example of background technology that addresses these problems, a dental extraoral vacuum device has been proposed to suction and remove flying objects such as blood, saliva, and cutting dust that tend to fly out of a patient's mouth during dental treatment. (Patent Document 1).

Another example is a surgical local exhaust system that deodorizes and cleans gas generated when a surgical procedure is performed on a living body (Patent Document 2).

The surgical local exhaust system described in Patent Document 2 uses a tube to place a suction port close to the gas generation position to suck in gas containing odors and particles, and deodorize and clean it using a deodorizing filter section. be.

FIG. 12 is a configuration explanatory diagram of a fourth embodiment of the medical device of the present invention, showing the configuration of a separate type of suction device.

Examples 1 to 4 of the medical device of the present invention will be described below with reference to the drawings.

FIG. 1 illustrates a case in which a first embodiment of the medical device of the present invention is applied to a laser handpiece 1 and a sealing cover 2 is of a narrow range type.

In FIG. 1, reference numeral 1 denotes a laser handpiece as a medical device, and a sealing cover 2 is attached to the head portion 11 of a laser probe 10 of the laser handpiece 1, and a medical device main body 12 is connected to the laser probe 10. It is composed of

Further, the sealing cover 2 has visibility (transparency) that allows the head section 11 of the laser probe 10 to see the treated area, and also prevents the laser beam 13 in the head section 11 of the laser probe 10 and the scattered light of the laser beam 13. The flexible contact part, which has the effect of absorbing light and can maintain airtightness with respect to the contact part with the surroundings of the treated area, is formed from a flexible material. It consists of: The airtight cover 2 may be made of a material that does not have the effect of absorbing light, or may be a combination of a material that has the effect of absorbing light and a material that does not have the effect of absorbing light. The material of the airtight cover itself may have a light-absorbing effect, or a material that does not have a light-absorbing effect may be coated with a light-absorbing paint.

Specific examples of the forming material include the following materials.
Thermoplastic elastomer, thermosetting elastomer, chlorosulfonated polyethylene rubber, butyl rubber, ethylene/propylene rubber, ethylene/vinyl acetate rubber, epichlorohydrin rubber, natural rubber, synthetic natural rubber, butadiene rubber, styrene/butadiene rubber, nitrile rubber, chlorobrene Rubber, urethane rubber, etc. are suitable, and thermoplastic elastomers include polycarbonate, polyvinyl chloride, polystyrene, styrene/acrylonitrile copolymer, styrene/butadiene/acrylonitrile copolymer, polyethylene, ethylene/vinyl acetate copolymer, Examples include fluorine-based materials such as polypropylene, polyacetal, polymethyl methacrylate, polymethyl methacrylate, modified acrylic, polyethylene terephthalate, polyurethane, and Teflon (registered trademark).
Examples of thermosetting elastomers include silicone rubber, fluororubber, phenol-formaldehyde, urea alpha-cellulose filling, melamine-formaldehyde, epoxy, furan, xylene, unsaturated polyester, and diallyl phthalate.

Further, the shape of the sealing cover 2 is required to be a shape that can correspond to the area to be treated, and in particular, in the laser handpiece 1, a configuration that can correspond to the measurement of the focal position 14 of the head section 11 is required. It is required to be formed by

That is, smoke and odor are generated when the laser beam 13 is incised, excised, and evaporated at the focal position 14, and the sealing cover 2 should be configured with a shape that can tightly seal the area around the generation site. is required, and it also becomes the measurement of the focal position 14 of the laser beam 13 as described above.
Further, the airtight cover 2 may be created based on data obtained by scanning the surrounding area including the treated area of the patient using a 3D scanner. In this case, it is possible to provide a sealing cover with improved fit based on the individual patient.
The contact portion with the patient is constituted by a flexible contact portion. The flexible contact portion may include a drive portion (not shown) such as a cylindrical rotating object to smoothly move the contact portion with the patient. The drive unit is configured to be embedded in the airtight cover 2, and by rotating a cylindrical rotating object, the drive unit smoothly moves through the contact area with the patient even during suction.
Alternatively, a viscous liquid may be applied around the area to be treated, and the viscosity of the liquid may cause the sealing cover 2 to slide over the area in contact with the patient.

Note that the sealing cover 2 is not limited to the illustrated cylindrical shape, but can be implemented as a polygonal cylindrical body or a shape that can appropriately correspond to the shape of the surrounding area of the treated area, if necessary. .

Then, the suction port 2b of the airtight cover 2 is opened, and the suction device 20 is equipped to the suction port 2b via a connecting member (vacuum hose) 21, and a small camera 30 is installed inside the airtight cover 2. It is composed of:

The intake port 40 is an intake port that opens in the airtight cover 2, and a mesh member 41 is stretched over the intake port 40, and a filter (not shown) and a check valve (not shown) are installed in the intake port 40. It is configured by being detachably attached. By providing a filter or a check valve in the intake port 40, it is possible to prevent the inside of the sealed cover from becoming a vacuum when suction is started, and to prevent dust and particles from the outside and transpiration generated inside the sealed cover when suction is finished. This has the effect of preventing contaminated substances from leaking to the outside.

That is, the removably attached filter is a filter that can remove smoke, odor, and particles generated during laser irradiation to the treatment area.

As the filter, it is preferable to use a known dust removal filter used for general air conditioning or dust removal, or a general adsorption filter suitable for removing odors and gases. For example, activated carbon, ACF (fibrous activated carbon), chemical adsorbent, ion exchange resin, zeolite, activated alumina, etc. may be used. Further, the filter may be loaded with a catalyst suitable for odor removal.

The effects of the filter can also be achieved by a configuration in which the filter is attached to the suction port 2b of the airtight cover 2.

Although details of the configuration of the suction device 20 in the configuration of the laser handpiece 1 are not shown in the drawings, it can be implemented by applying a suction device known in the technical field (for example, the product name " Whisper Liber 2” dental suction device pump JMDN: 7072700 manufactured by Yoshida Co., Ltd.).

Note that an application example of the suction device 20 used in the implementation will be shown below.

The suction device 20 is equipped with a vacuum motor for vacuum suction. The operating principle is as follows.
When the operation switch of the suction device 20 is turned on, the motor starts rotating, and the motor rotates the turbine of the blower connected by a belt.

The negative pressure generated by the rotation of the turbine causes suction by the suction device of the dental unit, and the sucked air is filtered by, for example, a filter for the suction device (not shown) and exhausted.

As the filter for the suction device, it is preferable to use a known air filter described below, which is suitable for removing particles and is used for general air conditioning or dust removal.
・MEPA filter (Medium Efficiency Particulate Air Filter)
A medium-performance filter is an air filter that has medium particle collection efficiency for particles with a particle size smaller than 5 mm.
・HEPA (High Efficiency Particulate Air Filter)
High performance filter. An air filter that has a particle collection efficiency of 99.97% or more for particles with a particle size of 0.3 mm at the rated flow rate, and an initial pressure loss of 245 Pa (25 mm H20) or less.
・ULPA (Ulpa Filter, English: Ultra Low Penetration Air Filter)
High performance filter. An air filter that has a particle collection efficiency of 99.9995% or more for particles with a particle size of 0.15 mm at the rated flow rate, and an initial pressure loss of 245 Pa (25 mmH20) or less.

Furthermore, the configuration of the small camera 30 in the configuration of the laser handpiece 1 is characterized in that the position or range of the treated area is confirmed. That is, although it is difficult to confirm the position of the treated area because it is covered by the airtight cover 2, the treatment can be performed safely because the position of the treatment area can be confirmed using the small camera 30 provided on the upper part of the airtight cover 2. .

Further, the location of the small camera 30 is not limited to the upper part of the airtight cover 2, as long as the location of the treated area can be confirmed.

That is, since smoke accumulates in the upper part, if the small camera 30 is installed above the airtight cover 2, it may be difficult to recognize the image. For example, by using a small camera to record before and after a treatment and how the treatment was performed, it can be saved in the medical record information and used when explaining things to the patient.

Furthermore, the small camera 30 may be used like a sensor. For example, if the small camera 30 operates in conjunction with the suction device 20 by image recognition and detection of the occurrence of smoke or gas from the treatment area, and the image recognition and detection of the smoke or gas being exhausted and disappeared. Suction device stops.

If the laser device has a scanning function that automatically scans the laser beam 13 back and forth and left and right, it can automatically scan according to the position or range of the treated area confirmed by the small camera 30.

In addition, in the configuration of the laser handpiece 1, the ON/OFF of the medical device main body 12 and the power supply of the suction device 20 operate in conjunction with each other, and the power of the suction device 20 is automatically turned on several seconds after the power of the medical device main body 12 is turned off. It is preferable to implement a configuration that can be cut accurately.

When the laser handpiece 1 having the above configuration is used to perform treatment on the affected area, especially in the case of this embodiment 1, the narrow-range sealing cover 2 is attached, and the patient's face, etc. It is suitable for use in areas with many unevenness.

The end surface 2a of the sealing cover 2 that contacts the skin of the affected area is made of a flexible material so that it can easily adhere to the treatment area, and further, by reducing the pressure with the suction device 20, the treatment can be performed snugly. It can be placed closely around the affected area.

Therefore, the area around the treated area can be sealed highly airtight with the sealing cover 2, and smoke, odor, particles, etc. generated during treatments such as incision, excision, evaporation, or coagulation of the treated area with the laser beam 13 can be sealed. The gas can be removed by suction by the suction device 20 through the connecting member 21 connected to the hermetic cover 2 while being smoke- and odor-proofed by the hermetic cover 2.

In addition, since the sealing cover 2 is made of a transparent member with visibility (transparency), visibility is good without blocking light, and the treatment area can be easily confirmed and the treatment area of the treatment affected area can be easily confirmed. By providing a small camera 30 that recognizes the location of the treatment area, it is possible to confirm the location of the treatment area.

Furthermore, during laser treatment, patients, practitioners, and people in the vicinity must wear safety goggles to protect their eyes from the scattered light of the laser. Since it is made of a material that is flexible, it is possible to omit wearing glasses.

Therefore, the desired treatment can be carried out based on the above-mentioned effects, and due to the simplicity of the operation, the treatment can be performed by a single practitioner without the need for a nurse.

Regarding the sealing cover 2 in the above configuration, an embodiment has been described in which it is attached to the head part 11, but it can be made to be reusable by being provided with a removable structure (not shown) and also to be disposable. It is also possible to do so.

In other words, smoke, odor, and particles are generated during treatments such as incision, excision, and evaporation using a laser device, and these may adhere to the inside of the sealing cover 2. Therefore, the molded material of the sealing cover 2 is heat-resistant and sterilization-resistant. Although it is possible to use it while cleaning it, a disposable embodiment is preferable.

However, as described above, the airtight cover 2 is made of a material that is heat resistant to 134° C. or higher, can be sterilized at high temperature in an autoclave, and has drug resistance.

It is used for areas with a lot of unevenness such as the face, whereas it is used for areas below the patient's neck that have less unevenness.

The upper part 2c and the lower part 2d of the airtight cover 2 are divided into two parts, and the lower part 2d having the contact end surface 2a is made of a material more flexible than the molding material of the upper part 2c, such as silicone rubber. Consisting of:
Note that the configuration of the airtight cover 2 is preferably implemented as described in the above paragraph [0032] .

Further, touch sensors 60 are installed at required intervals in the circumferential direction of the close contact end surface 2a.

The touch sensor 60 is configured to be able to operate the medical devices 1 and 50 in conjunction with the suction device 20 by detecting that the area to be treated is covered.

Therefore, the sensor is configured by installing a pressure sensor, a light sensor, a capacitance sensor, a temperature sensor, or the like.

Note that the configuration of the operation in conjunction with the suction device 20 is not limited to the configuration using the touch sensor 60, but can be implemented by a configuration operated by the operation section of the laser device of the medical device 1, 50.

Therefore, the laser device 50 as the medical device of the second embodiment described above can perform the desired treatment while producing the same effects as the laser handpiece 1 of the first embodiment.

FIG. 3 shows the configuration of an embodiment in which the suction device 20 in Examples 1 and 2 is integrated with a medical device.

That is, the suction device 20 and the drive power circuit section 31 of the small camera 30 installed in the airtight cover 2 are integrated into the medical device main body 12, and the control section 80 of the laser oscillation tube 70 of the medical devices 1 and 50 and the air supply source 71 is integrated. The configuration is such that necessary operations in the first and second embodiments can be performed by controlling the display unit 81 and displaying the information via the display unit 81.
