An endoscopic forceps channel cleaning device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, the endoscope channel cleaning device according to the embodiment of the present invention may be used to disinfect and clean an endoscope 50, and includes a cleaning brush 10, a sonic motor 20, and a peristaltic pump 30.

Specifically, the washing brush 10 includes a central hose 101 and bristles 102 disposed on an outer circumferential surface of the central hose 101, one end of the central hose 101 is an open end D10, the other end of the central hose 101 is a closed end D11, and a liquid outlet is disposed on a tube wall of the central hose 101; the bristles 102 are configured such that when the washing brush 10 is passed into the jaw H50 of the endoscope 50, the bristles 102 are brought into contact with the inner wall of the jaw H50.

That is, the washing brush 10 mainly comprises a center hose 101 and bristles 102 arranged on the outer peripheral surface of the center hose 101, on one hand, the center hose 101 can be inserted into the channel H50 of the endoscope 50 as a carrier of the bristles 102, so that the bristles 102 enter the channel H50 of the endoscope 50 along with the center hose 101 and contact the inner wall of the channel H50, and further the inner wall of the channel H50 can be washed by the bristles 102, on the other hand, the center hose 101 can be used as a washing liquid delivery channel, and the washing liquid can be delivered into the center hose 101 and flow out to between the bristles 102 and the inner wall of the channel H50 through the liquid outlet hole on the center hose 101, so that when the bristles 102 are washed, the channel H50 is washed and disinfected by the washing liquid, and the dirt on the channel H50 can be easily removed and disinfected.

A sonic motor 20 is connected to the closed end D11 of the center hose 101 to generate vibration of a predetermined frequency to vibrate the washing brush 10 in the jaw H50. A peristaltic pump 30 is connected to the open end D10 of the central hose 101 for delivering a cleaning liquid into the central hose 101, so that the cleaning liquid flows between the bristles 102 and the inner wall of the channel H50 through the liquid outlet.

That is, the sound wave motor 20 can drive the central hose 101 to vibrate at a predetermined frequency, preferably, the predetermined frequency is an ultrasonic frequency, when the central hose 101 vibrates, the bristles 102 can be driven to vibrate, and the vibrating bristles 102 act on the inner wall of the jaw path H50, so as to achieve a faster and more sufficient cleaning effect on the inner wall of the jaw path H50. The peristaltic pump 30 can be used for conveying the cleaning liquid into the central hose 101, the cleaning liquid flows out to a position between the brush bristles 102 and the inner wall of the clamp channel H50 through liquid outlet holes in the central hose 101, and when the brush bristles 102 are used for cleaning, the vibration of the brush generates a cavitation effect on the cleaning liquid, an acceleration effect is achieved, and sound wave cleaning is achieved.

It should be noted that, as a medical care provider, the inventor of the present application found in practice that when the endoscope 50 is manually washed and disinfected during the post-operation cleaning and disinfecting maintenance, the forceps channel H50 has a narrow and thin aperture, and even though the endoscope is washed by inserting a tool such as a brush or a cotton swab into the aperture, it is still difficult to achieve a good cleaning effect, and the efficiency is low. Although the ultrasonic cleaning apparatus has a relatively good cleaning effect, the inventor has found that the ultrasonic cleaning apparatus cannot be applied to cleaning of the jaw H50 of the endoscope 50 because the ultrasonic cleaning apparatus in the related art provides only one cleaning tank H40, and can only put the endoscope 50 in its entirety into the cleaning tank H40, and then clean the endoscope 50 by transmitting the cleaning liquid in the cleaning tank H40 using the ultrasonic waves provided by the ultrasonic cleaning apparatus, which has a poor cleaning effect on the jaw H50 of the endoscope 50.

Based on the above findings and studies, the inventors adopted the above technical solution of the present application to solve the above problems. According to the endoscope clamp path cleaning device provided by the embodiment of the invention, on one hand, the sound wave motor 20 is used for providing vibration with preset frequency, so that the washing brush 10 passed into the jaw H50 of the endoscope 50 is vibrated at a predetermined frequency, and on the other hand, cleaning solution is fed into the central hose 101 of the washing brush 10 by the peristaltic pump 30, and the cleaning solution can flow into between the brush bristles 102 and the inner wall of the channel H50 through the liquid outlet hole of the central hose 101, in this way, the bristles 102 can brush the inner wall of the channel H50 when vibrating, so that the dirt on the inner wall of the channel H50 can be brushed off, and at the same time, greater cavitation and acceleration of the cleaning fluid can occur as the bristles 102 vibrate, the cleaning agent has direct and indirect effects on dirt, so that the dirt is dispersed, emulsified and stripped, and the aim of more fully cleaning is fulfilled.

It is emphasized that the action of the vibration of the bristles 102 on the cleaning liquid can generate stronger cavitation and acceleration effects which directly bring about better cleaning and disinfecting effects than the ultrasonic vibration directly applied to the cleaning tank H40 in the related art.

Referring to fig. 3 and 5, in one embodiment of the present invention, the bristles 102 are arranged spirally about the axis of the central hose 101 such that a spiral channel H10 is defined between the bristles 102 and the inner wall of the jaw H50.

In this embodiment, the bristles 102 are arranged spirally to define a spiral channel H10, in the cleaning and disinfecting process, the vibration of the bristles 102 and the cavitation action of sound waves can make the dirt on the inner wall of the channel H50 fall off, and because the spiral channel H10 is formed between the bristles 102 and the inner wall of the channel H50, the fallen dirt easily enters the spiral channel H10 along with the vibration, after the cleaning is completed, when the cleaning brush 10 is pulled out, the dirt easily falls off from the cleaning brush 10, so that the cleaning efficiency of the bristles 102 on the inner wall of the channel H50 is higher, and the cleaning effect is also better.

Advantageously, the outlet holes are in plurality, arranged in a helix along the axis of central hose 101 and all communicating with helical channel H10.

That is, the spiral path of the plurality of liquid outlet holes coincides with the spiral channel H10, so that when the peristaltic pump 30 delivers the cleaning liquid into the central hose 101, the cleaning liquid can rapidly enter the spiral channel H10 through each liquid outlet hole, and then the cleaning liquid flows in the spiral channel H10, so that the dirt in the spiral channel H10 flows along with the cleaning liquid and finally flows out from the forceps channel outlet H502 of the endoscope 50, and thus, the flow of the cleaning liquid in the spiral channel H10 can be utilized to promote the discharge of the dirt during the cleaning process, thereby improving the cleaning efficiency and the cleaning effect.

More advantageously, a sealing plug 103 is disposed around central hose 101, said sealing plug 103 being disposed adjacent to said open end D10 for sealing the channel inlet H501 of said channel H50.

After the washing brush 10 is inserted into the channel H50 from the channel inlet H501, the channel inlet H501 is blocked by the sealing plug 103, so that the cleaning solution can be ensured to flow from the channel inlet H501 to the channel outlet H502 in the spiral channel H10, and a better pollution discharge effect is achieved.

Referring to fig. 1-2, in some embodiments of the present invention, the cleaning container 40 further comprises a cleaning tank H40, wherein the cleaning tank H40 is adapted to contain the cleaning solution. When the endoscope 50 is cleaned and disinfected, the whole endoscope 50 can be put into the cleaning tank H40 and the endoscope 50 can be soaked, disinfected and cleaned with the cleaning liquid (e.g., enzyme cleaning liquid) in the cleaning tank H40, whereby the whole endoscope 50 can be disinfected and cleaned.

Optionally, the cleaning vessel 40 has an operating table adapted to hold the endoscope 50, and the sonic motor 20 and peristaltic pump 30 are disposed on the cleaning vessel 40.

That is, when the endoscope 50 is entirely sterilized by the cleaning liquid in the cleaning tank H40, the forceps channel H50 of the endoscope 50 can be cleaned and sterilized by the cleaning brush 10, the peristaltic pump 30, and the acoustic wave motor 20 on the operation table of the cleaning container 40 by the acoustic wave, which makes the operation more convenient.

Referring to fig. 1 to 2, in an embodiment of the present invention, a first positioning member 401 and a second positioning member 402 are provided on an operation table, the first positioning member 401 is used for positioning an operation portion 501 of the endoscope 50, and the second positioning member 402 is used for positioning an insertion portion 502 of the endoscope 50.

When the cleaning brush 10, the peristaltic pump 30 and the sound wave motor 20 are used to perform sound wave cleaning and disinfection on the forceps channel H50 of the endoscope 50 on the operation table, the endoscope 50 can be firstly placed on the operation table, the first positioning member 401 is used to position the operation portion 501 of the endoscope 50, and the second positioning member 402 is used to position the insertion portion 502 of the endoscope 50, so that the endoscope 50 can be kept relatively fixed on the operation table, and the disinfection and cleaning operation is convenient.

Illustratively, peristaltic pump 30 has an inlet port in communication with cleaning tank H40 via an inlet tube 301 and an outlet port in communication with open end D10, such that inlet tube 301 draws cleaning fluid from the inlet tank and delivers it to central hose 101 via the outlet port of peristaltic pump 30.

In order to facilitate the connection between the peristaltic pump 30 and the acoustic motor 20 and the two ends of the central hose 101, a pipe joint 104 is arranged at the open end D10 of the central hose 101, the pipe joint 104 is inserted into a liquid outlet of the peristaltic pump 30, a non-circular insertion joint 105 is arranged at the closed end D11 of the central hose 101, a connecting sleeve is arranged on an output shaft of the acoustic motor 20, and the connecting sleeve is sleeved with the insertion joint 105, so that the peristaltic pump 30 and the acoustic motor 20 can be quickly connected with the two ends of the central hose 101.

Advantageously, cleaning container 40 also has a collection trough H41, and when endoscope 50 is placed on the operating deck, channel outlet H502 of channel H50 is located above collection trough H41. it will be appreciated that collection trough H41 may be in communication with cleaning trough H40, or may be out of communication with cleaning trough H40, so that cleaning fluid and contaminants within spiral channel H10 may drain into collection trough H41 during cleaning.
