TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste liquid scattering prevention device of an endoscope for preventing the discharge of waste liquid in a body cavity from a treatment tool insertion port which is an entrance of a forceps channel.
[0002]
[Prior art]
In general, a forceps channel for passing treatment tools is inserted into the insertion portion of the endoscope, and a distal end outlet of the forceps channel is opened at a distal end of the insertion portion. It is open.
[0003]
However, as it is, the pressure in the body cavity causes the waste fluid in the body cavity to squirt out of the treatment instrument insertion port on the operation unit side through the forceps channel, thus contaminating the surgeon and its surroundings.
[0004]
Therefore, a so-called forceps plug made of, for example, a rubber valve having a slit is provided in the treatment tool insertion port so as to prevent such waste liquid ejection and to allow the treatment tool to be inserted into and removed from the forceps channel. Is installed.
[0005]
[Problems to be solved by the invention]
However, when the treatment tool is passed through the forceps plug, the slit of the rubber valve is pushed open and a gap is created between the end of the slit and the outer peripheral surface of the treatment tool, and contaminants are ejected from that part. There are many cases. In particular, in the case of a treatment tool having a coil pipe as a sheath, since there is a spiral gap on the outer peripheral surface, the waste liquid is easily ejected.
[0006]
Further, in the case of a treatment tool in which an operation wire or the like is inserted into the sheath so as to be able to advance and retreat, there is a gap between the sheath and the operation wire.
[0007]
In this way, when the intracorporeal contaminant spouts from the treatment instrument insertion port, the contaminant may be applied to the surgeon's face or hand or scattered around, resulting in a very unsanitary condition. However, it is difficult to completely prevent the ejection of such waste fluid in the body cavity.
[0008]
Therefore, an object of the present invention is to provide a waste liquid scattering preventive device for an endoscope that can prevent sanitary sewage in a body cavity from spilling out of a treatment tool insertion port and perform an endoscope inspection in a sanitary manner. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an endoscope for preventing waste liquid from splashing, which is made of a flexible water-absorbing material for covering a treatment tool insertion port arranged in an operation section of the endoscope. A liquid absorbing member is detachably attached to the vicinity of the treatment instrument insertion port by pressure-sensitive bonding.
[0010]
Note that the treatment instrument insertion port may be disposed at a tip of a protrusion formed on the operation unit, and the waste liquid absorbing member may be pressure-sensitively bonded to an outer peripheral surface of the protrusion.
[0011]
Alternatively, the treatment instrument insertion port is disposed at a tip of a projecting portion formed in the operation section, and the waste liquid absorbing member senses from an outer peripheral surface of the projecting section to an outer peripheral surface of the operation section. It may be pressure bonded.
[0012]
Further, the treatment instrument insertion port may be arranged on a flat surface of the operation unit, and the waste liquid absorbing member may be pressure-sensitively bonded to the flat surface.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes an operation section of an endoscope, and an insertion section 2 to be inserted into a body cavity is connected to a lower end of the operation section.
[0014]
In the insertion portion 2, a forceps channel 4 opening at the tip thereof is inserted over the entire length. The proximal end side of the forceps channel 4 communicates with a treatment tool insertion opening 5 formed at the distal end of a projection 3 projecting obliquely upward from the lower end of the operation unit 1. The outer wall member of the protrusion 3 is formed in a cylindrical shape.
[0015]
A forceps plug 6 which is normally closed and which is pushed and opened only when a treatment tool is inserted from the treatment tool insertion port 5 into the forceps channel 4 is disposed in the protrusion 3 immediately inside the treatment tool insertion port 5. ing.
[0016]
An air supply / water supply operation valve 7 and a suction operation valve 8 are disposed on the front side in the upper half of the operation unit 1, and a curved portion (not shown) formed near the distal end of the insertion unit 2 is remotely operated. A bending operation knob 9 for performing a bending operation is arranged on the side surface. A grip portion 1a is provided between the portion and the lower end of the operation portion 1.
[0017]
Reference numeral 20 denotes a waste liquid scattering prevention device for an endoscope, as shown in FIG. 2, which is formed by folding a plurality of water-absorbing materials, such as flexible gauze, and superimposing a plurality of them to form a rectangular sheet-like waste liquid absorbing material. A member 21 is formed, and a pressure-sensitive adhesive surface 22 is formed near one short side thereof.
[0018]
The pressure-sensitive adhesive surface 22 hardly deteriorates in a normal environment, and is adhered by strongly pressing the surface to be adhered. However, the adhesive force to a plastic surface, a metal surface, or the like is not strong, and can be peeled off by applying a little strong force.
[0019]
The waste liquid absorbing member 21 is sewn on both sides of the pressure-sensitive adhesive surface 22 with a sewing machine. 23 is the sewing seam. Note that the waste liquid absorbing member 21 is not limited to gauze, and a flexible and water-absorbing material such as a sponge, a nonwoven fabric, a continuous foam such as a high-molecular-weight water-containing polymer, and a PVA sponge can be used.
[0020]
The waste liquid scattering prevention device 20 formed in this manner is attached to the operation unit 1 by pressing the pressure-sensitive adhesive surface 22 to the outer peripheral surface near the lower end of the protruding portion 3 and adhering the same.
[0021]
FIG. 3 shows only the waste liquid scattering prevention device 20 in this state. The pressure-sensitive adhesive surface 22 has a U-shape along substantially half of the outer peripheral surface of the protrusion 3, and the waste liquid absorbing member 21. Is pointed upward.
[0022]
Then, as shown in FIG. 1, the waste liquid absorbing member 21 is arranged so as to cover the treatment instrument insertion port 5 at the protruding end of the protruding portion 3. By doing so, even if the contaminant in the body cavity that has passed through the forceps channel 4 gushes out of the treatment instrument insertion port 5, the contaminant is absorbed by the contaminant absorbing member 21 and scatters around. Do not hang on your hands or face.
[0023]
When the treatment tool is inserted into the forceps channel 4, as shown in FIG. 4, the treatment tool insertion port 5 is slightly opened and the treatment tool insertion port 5 is slightly U-shaped. 100 is inserted into the forceps channel 4 from the treatment instrument insertion port 5. In this way, even if the waste liquid in the body cavity leaks out of the treatment tool insertion port 5 while using the treatment tool 100, it can be absorbed by the waste liquid absorbing member 21.
[0024]
FIG. 5 shows a case in which the width of the waste liquid absorbing member 21 is formed wide and the pressure-sensitive adhesive surface 22 is bonded from the outer peripheral surface of the protruding portion 3 to the outer peripheral surface of the operation portion 1 on the base side thereof. By doing so, the waste liquid scattering prevention tool 20 can be bonded in a more stable state. FIG. 6 shows only the waste liquid scattering prevention device in that state.
[0025]
FIG. 7 shows a case where the waste liquid absorbing member 21 is attached to the outer peripheral surface of the protrusion 3 so as to make a full circumference. In this case, since the pressure-sensitive adhesive surface 22 is adhered to the outer peripheral surface of the protruding portion 3 in a dust-like manner, the waste liquid scattering prevention device 20 can be more stably adhered.
[0026]
FIG. 8 shows a state in which the treatment tool 100 is used when the waste liquid scattering prevention tool 20 is attached to the operation unit 1 in such a manner. As shown in FIG. The treatment tool 100 is passed through the space of the waste liquid absorbing member 21 having the shape.
[0027]
FIG. 10 shows a case in which the treatment instrument insertion port 5 is provided on the flat surface of the operation unit 1. What is necessary is just to cover the treatment instrument insertion port 5 with the liquid absorbing member 21.
[0028]
When the treatment tool 100 is used, the waste liquid absorbing member 21 may be withdrawn from above the treatment tool insertion port 5. The slit 24 may be formed as shown, and the treatment tool 100 may be passed through the slit 24.
[0029]
