Description

The present invention relates to an endoscope cleaning adapter attached to an operation unit of an endoscope.

In recent years, endoscopes have been widely used in the medical field and the like. In particular, an endoscope used in the medical field is used by inserting an insertion portion of the endoscope into a subject. Therefore, after using the endoscope, it is required to perform sufficient cleaning, disinfection, sterilization and the like.

Generally, the operation unit of the endoscope is detachably provided with a suction button for controlling the suction operation of the endoscope and an air supply / water supply button for controlling the air supply operation and the water supply operation of the endoscope. There is. The suction button is inserted into a suction cylinder provided in the operation unit of the endoscope. The air supply / water supply button is inserted into an air supply / water supply cylinder provided in the operation unit of the endoscope. When cleaning the endoscope, remove the suction button and the air supply / water supply button from the suction cylinder and the air supply / water supply cylinder, respectively, and replace the openings of the suction cylinder and the air supply / water supply cylinder. A cleaning adapter for an endoscope, which introduces a cleaning means such as a cleaning liquid into a conduit in the endoscope so as to close the endoscope, is attached to an operating portion of the endoscope.

The conventional cleaning adapter for an endoscope is fixed to the operating portion of the endoscope by a slide member or the like.

For example, Japanese Patent Application Laid-Open No. 2006-55325 includes a fixing member to which a tubular member connected to a suction cylinder and an air supply / water supply cylinder is attached, and a slide member slidably attached to the fixing member. Mirror cleaning couplers are disclosed. The slide member has a bottom portion that sandwiches a flange formed on the peripheral edge of the end of the opening of the cylinder. The coupler disclosed in Japanese Patent Application Laid-Open No. 2006-55325 is attached to the operation panel surface of the endoscope by sliding the slide member in a predetermined direction.

Further, in Japanese Patent Application Laid-Open No. 2004-4969, the air supply / water supply cylinder cleaning connection portion and the suction cylinder cleaning connection portion connected to the air supply / water supply cylinder port and the suction cylinder port are arranged in a row, respectively. A cleaning adapter for an endoscope is disclosed, which includes a connecting plate and a sliding portion that can slide along an arrangement direction of these connecting portions. The sliding portion includes a cylinder port gripping portion capable of gripping an air supply / water supply cylinder port and a suction cylinder port. The cleaning adapter for an endoscope disclosed in Japanese Patent Application Laid-Open No. 2004-4969 is attached to an operating portion of an endoscope by sliding the sliding portion in a predetermined direction.

When the air supply / water supply button 137 is in the initial state, the gas supplied from the air supply device (not shown) is supplied to the air supply line 165 via the air supply port of the endoscope connector 141. The air supply / water supply button 137 is formed with a hole (not shown) that communicates with the air supply line 165 and the outside. Therefore, the gas supplied to the air supply line 165 is discharged to the outside through the hole of the air supply / water supply button 137. Further, when the air supply / water supply button 137 is in the initial state, a flow path connecting the air supply line 165 and the air supply line 166 is formed. Therefore, when the user presses the hole of the air supply / water supply button 137, the gas supplied to the air supply line 165 is sent to the air supply line 166 and fluid is sent through the air supply / water supply line 170. It is discharged from the outlet 114.

When the air supply / water supply button 137 is pushed in one step from the initial state, the gas supplied to the air supply line 165 is supplied to the liquid supply tank via the water supply port of the endoscope connector 141. As a result, the pressure in the liquid feeding tank becomes high, and the liquid in the liquid feeding tank is sent from the liquid feeding tank to the water pipe line 168. Further, when the air supply / water supply button 137 is pushed in one step from the initial state, a flow path connecting the water supply pipe line 168 and the water supply pipe line 167 is formed. Therefore, the liquid sent to the water supply line 168 is sent to the water supply line 167 and discharged from the fluid delivery port 114 via the air supply / water supply line 170.

When the air supply / water supply button 137 is pushed in two steps from the initial state, a flow path connecting the water supply pipe line 168 and the balloon water supply pipe line 169 is formed. Therefore, the liquid sent to the water pipe line 168 is sent to the balloon water pipe line 169, discharged from the balloon liquid supply opening 161b, and supplied to a balloon (not shown).

FIG. 29 shows a state in which the support members 16A and 16B are fitted into the support groove 15Bc3.

In the state shown in FIG. 27, the portion of the tubular portion 15C of the switching member 15 including the suction pipeline liquid supply port 15b protrudes from the first suction pipeline liquid supply port 13a. As a result, a flow path connecting the introduction port 15a of the switching member 15 and the treatment tool insertion channel 118 is formed. As a result, the cleaning liquid or the like can be sent from the introduction port 15a to the treatment tool insertion channel 118. The sealing member 17 is used to form the flow path.

In the state shown in FIG. 28, the suction pipeline liquid supply port 15b of the switching member 15 communicates with the second suction pipeline liquid supply port 13b. As a result, a flow path connecting the introduction port 15a of the switching member 15 and the suction pipe line 163 is formed. As a result, the cleaning liquid or the like can be sent from the introduction port 15a to the suction pipe line 163. The sealing members 17 and 18 are used to form the above-mentioned flow path.

By the way, it is also conceivable to introduce the cleaning liquid from the opening of the suction cylinder 132 without using the suction side connecting member 10 and to send the cleaning liquid to a plurality of pipelines inside the endoscope 100. In this case, since the cleaning liquid is simultaneously sent to the plurality of pipelines, the cleaning liquid is dispersed and the flow rate of the cleaning liquid flowing through each pipeline is reduced. Further, in general, since the pipe diameters of a plurality of pipes are not the same, there is a difference in the flow rate of the cleaning liquid flowing through each pipe. In a pipeline with a small pipeline diameter, this also reduces the flow rate of the cleaning liquid flowing through the pipeline. In order to sufficiently clean a pipeline having a small pipeline diameter, the number of cleaning operations must be increased, which increases the burden on the user. In particular, in an ultrasonic endoscope such as the endoscope 100 in the present embodiment, the number of conduits is relatively large, and the above problem occurs remarkably.

On the other hand, in the present embodiment, by changing the position of the switching member 15 in the third direction D3, the cleaning liquid is sent from the treatment tool insertion channel 118, the suction pipe line 163, and the balloon suction pipe line 164.
