In minimally invasive laparoscopic surgery, if surgery or resection is required in the human body, pneumoperitoneum is required in the abdominal cavity of the human body during the operation. Establishing pneumoperitoneum is an important operation process of the operation. When pneumoperitoneum is sufficient, the distance between the abdominal cavity and the internal organs increases, expanding the surgical field of vision. Laparoscopic surgery requires an opening in the patient's abdomen and the operation is performed under laparoscopic observation. At this time, pollutants in the abdominal cavity may contaminate the lens. The lens needs to be pulled out, cleaned and then put back in. The operation is cumbersome and may cause secondary infection, which is not good for the patient and will increase the workload of the doctor.

DETAILED DESCRIPTION

[0036] The present invention aims to provide an intracavitary endoscope cleaning and smoke exhaust device to address the deficiencies of the prior art, which is specifically implemented by the following technical solutions: Reference Figure 4 , Figure 5 An intracavitary endoscope cleaning and smoke exhaust device is characterized in that it includes an outer sleeve 100, a locking fixing seat 200, a self-adjusting sealing cap 201, a first cover body 300, a second cover body 400, an inner core tube 500, a first air blocking valve 202, and a second air blocking valve 501.

[0037] Reference Figure 6 , Figure 7 The first cover 300 and the second cover 400 are both provided with openings in the center, so that the surgical camera can enter the inner core tube 500. A water inlet and a water outlet are respectively provided at the top ends of the first cover 300. The first cover 300 is detachably provided on the second cover 400. A protrusion is provided at the bottom of the first cover 300, which can be installed in the groove preset at the top of the second cover 400, thereby combining them into a whole.

[0038] Reference Figure 6 , Figure 7 After the first cover body 300 and the second cover body 400 are combined, two channels are formed on both sides thereof, for installing a suction switch 204 respectively.

[0039] Reference Fig.15 A sealing ring 205 is provided on the part of the suction switch 204 disposed in the channel, and the sealing ring 205 is in close contact with the inner wall of the channel.

[0040] Reference Figure 6 , Figure 7 The suction switch 204 located on the water inlet side is used to control the water inlet of the device, and the suction switch 204 located on the water outlet side is used to control the water outlet of the device. The water inlet and water outlet on the first cover body 300 are respectively connected to the channels below them, and through holes are provided at the lower ends of the two channels so that water can flow into the channels from the through holes.

[0041] Reference Figure 4 , Figure 5 The self-adjusting sealing cap 201 is arranged below the first cover body 300 and on the first air blocking valve 202 .

[0042] Reference Fig.17 There is a through hole in the center of the self-adjusting sealing cap 201. The diameter of this through hole is smaller than the diameter of the camera and the puncture cone. The self-adjusting sealing cap 201 is made of silicone and has a certain stretching range. When the camera and the puncture cone pass through the self-adjusting sealing cap 201, because their diameters are larger than the through hole of the self-adjusting sealing cap 201, they will be in close contact with the through hole of the self-adjusting sealing cap 201, isolating themselves from air and water flow.

[0043] Reference Figure 4 , Figure 5 The first air blocking valve 202 and the self-adjusting sealing cap 201 are arranged inside the structure formed by the first cover body 300 and the second cover body 400.

[0044] Reference Fig.17 , Fig.18 The outermost edge diameter of the first air blocking valve 202 is larger than the inner diameter of the second cover body 400, and the bottom of the first air blocking valve 202 is an openable and closable structure, and its bottom is divided into four parts. The camera or puncture cone passing through the self-adjusting sealing cap 201 continues to pass through the first air blocking valve 202 and then enters the inner core tube.

[0045] Reference Figure 4 , Figure 5After the first air blocking valve 202 is placed on the inner circle of the second cover body 400, the self-adjusting sealing cap 201 is placed on the first air blocking valve 202, and finally the first cover body 300 is placed on the second cover body 400. The bottom of the second cover body 400 is detachably connected to the top of the locking fixing seat 200. A protrusion is provided at the bottom of the second cover body 400, which can be installed in the preset groove at the top of the locking fixing seat 200, thereby combining them into a whole. A protrusion is provided at the bottom of the locking fixing seat 200, which can be installed in the preset groove at the top of the outer sleeve 100.

[0046] Reference Figure 8 The locking fixing seat 200 is hollow inside, and an opening corresponding to the outer sleeve 100 is provided below it, so that the camera and the puncture cone can normally enter the outer sleeve 100 and the inner core tube 500 provided at the lower end thereof.

[0047] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 Through holes are provided on both sides of the top of the locking fixing seat 200, and the top of the through hole is connected with the through holes at the lower ends of the two channels formed by the combination of the first cover body 300 and the second cover body 400 above it. Water can flow into the outer sleeve 100 from a through hole, and then be sucked into the inner core tube 500 to clean the camera, and then be sucked out from the inner core tube 500, enter the outer sleeve 100, and be sucked out of the device from another through hole.

[0048] Reference Figure 8 An air outlet is arranged at the position where the perpendicular bisector of the connecting line of the horizontal positions of the two through holes intersects with one end of the locking fixing seat 200, and the air outlet passes through the locking fixing seat 200. An air inlet valve seat is arranged on the air outlet arranged on the locking fixing seat 200. The air inlet valve seat is a hollow structure with a cylindrical shape as a whole and penetrates from top to bottom. It is vertically arranged on the air outlet, and the air valve switch 203 is arranged on the air inlet valve seat to control smoke exhaust.

[0049] Reference Figure 5 , Figure 8 , Fig. 9The inner ring of the locking fixing seat 200 is detachably provided with an inner core tube 500, a protrusion is provided on the outer wall of the upper end of the inner core tube 500, and a groove is provided on the inner wall of the lower end of the locking fixing seat 200. The two cooperate with each other so that when the inner core tube 500 is placed in the locking fixing seat 200, its position is fixed. Because three grooves for water flow and gas are respectively provided on the outer wall of the inner core tube 500, it is necessary to ensure that the positions corresponding to the tops of the three grooves will not change. At this time, the protrusion provided on the outer wall of the upper end of the inner core tube 500 and the groove provided on the inner wall of the lower end of the locking fixing seat 200 can ensure that the inner core tube 500 is in the correct position inside the device, thereby avoiding the subsequent flow of water and gas.

[0050] Reference Figure 4 , Figure 5 The lower end of the inner core tube 500 is detachably provided with a second air blocking valve 501. Reference Fig.16 The bottom of the second air blocking valve 501 is an openable and closable structure. The bottom plane of the second air blocking valve 501 is divided into several parts with its center as the center, and its bottom is an openable and closable structure. In the absence of external force, the second air blocking valve 501 is in a closed state. When a camera or a puncture cone is used to push the inner core tube 500, the second air blocking valve 501 can be pushed open to complete subsequent operations.

[0051] Reference Figure 4 , Figure 5 The lower ends of the through holes and the end of the air outlet arranged on both sides of the top of the locking fixing seat 200 are connected to the inside of the outer sleeve 100, and when the two are connected, the inner core tube 500 is arranged inside the outer sleeve 100, and the second air blocking valve 501 arranged at the bottom of the inner core tube 500 is tightly fitted with the inner wall of the outer sleeve 100, thereby isolating water vapor.

[0052] Reference Fig. 9 The inner core tube 500 has a plurality of water inlet holes and water outlet holes at its lower end. The inner core tube 500 has two upper and lower horizontal grooves at its lower end. The water inlet holes on the inner core tube 500 are positioned higher than the water outlet holes. The purpose is to ensure that when the water flow is sucked into the outer sleeve 100, it can be completely sucked out when it is sucked out. If the water outlet is positioned higher, water droplets may remain below it, increasing the probability of secondary infection.

[0053] Reference Fig. 9, several water inlet holes and water outlet holes are respectively arranged in corresponding grooves, two horizontal grooves are respectively extended upward on the outer wall of the inner core tube 500, and the upper end of the groove where the water inlet hole is located extends to the lower end of the through hole on the locking fixing seat 200 located below the vertical position of the water inlet on the first cover body 300, so that the inlet water flow and the outlet water flow can enter and flow out of the outer sleeve 100 respectively through the nearest path, and the upper end of the groove where the water outlet hole is located extends to the lower end of the through hole on the locking fixing seat 200 located below the vertical position of the water outlet on the first cover body 300. This design is to better guide the water flow in the groove, limit the flow path of the water flow to the greatest extent, avoid secondary infection, and limit the groove for the water flow, which can enhance the suction force and ensure thorough cleaning of the camera.

[0054] Reference Fig. 9 A smoke guide groove is provided below the groove where the water outlet is located, and the upper end of the smoke guide groove extends to the air outlet position on the locking fixing seat 200, so that smoke and gas flow out of the outer sleeve 100 through the nearest path.

[0055] Reference Fig. 9 The lower end of the inner core tube 500 is also provided with a plurality of smoke guiding protrusions, each of which is provided with a smoke guiding groove, which passes through the edge of the lower end of the inner core tube 500 and is connected with the smoke guiding groove at its upper end. The upper end of the second air blocking valve 501 is arranged at the edge of the lower end of the inner core tube 500, and the four smoke guiding claws are wrapped by the second air blocking valve 501. The second air blocking valve 501 is tightly fitted with the lower end of the inner core tube 500, and a gap is left between the smoke guiding groove and the second air blocking valve 501. The top of the second air blocking valve 501 is wrapped on a circle of protrusions at the lowest end of the inner core tube 500, and this circle of protrusions has a groove that is connected with the smoke guiding groove on the smoke guiding protrusion. Used to guide smoke, under normal circumstances the second air blocking valve 501 is in a closed state. At this time, because the second air blocking valve 501 is in close contact with the inner wall of the outer sleeve 100, the exhaust and smoke exhaust operation cannot be completed. At this time, you only need to aim the camera at the desired exhaust and smoke exhaust position, and then turn on the air valve switch 203. At this time, the suction can be completed, and the gas enters the inner core tube 500 from the opened second air blocking valve 501, and then under the action of suction, the gas is sucked into the groove on the circle of protrusions at the lower end of the inner core tube 500 from the smoke guide grooves on the four smoke guide claws, and finally enters the smoke guide groove above it and is sucked out of the device to complete the exhaust and smoke exhaust operation.

[0056] Reference Fig.10 A continuous thread structure is arranged on the outer wall of the outer sleeve 100. In order to be more closely integrated with the human body, the thread can be rotated into the human body after a small incision is made on the human body surface, so that it is closely integrated with the human body, ensuring the stability of subsequent surgical operations and reducing the difficulty of the doctor's work. Because it has a fixing effect, even one person can easily complete the subsequent work.

[0057] Reference Fig.11 , Fig.12 An intracavitary endoscope cleaning and smoke exhaust device also includes a puncture cone 600 and a puncture cone fixing cover 601. The puncture cone fixing cover 601 is detachably connected to the puncture cone 600. The puncture cone fixing cover 601 is provided with a protrusion matching the water inlet and water outlet provided on the top of the first cover body 300. The puncture cone 600 is detachably arranged in the outer sleeve 100. The lower end of the puncture cone 600 is provided with a blade, which can complete the puncture operation.

[0058] Reference Figure 4 , Figure 5 An intracavitary endoscope cleaning and smoke exhaust device also includes a protective cover 700, which is arranged outside the assembled first cover body 300, the second cover body 400, and the locking fixing seat 200, and tightly wraps them. Openings are respectively provided on both sides of the top of the protective cover 700, corresponding to the water inlet and the water outlet. An opening corresponding to the opening of the first cover body 300 is provided in the middle of the top, and an opening corresponding to the outer sleeve 100 is provided at the bottom. The protective cover 700 can tightly wrap the gap of the combined part of the device, reducing the risk of infection from the gap by bacteria and other impurities.

[0059] Embodiment 1: First, place the first air blocking valve 202 on the inner circle of the second cover body 400, the outer circle diameter of the first air blocking valve 202 is larger than the inner circle diameter of the second cover body 400, and then place the self-adjusting sealing cap 201 on the first air blocking valve 202, and then install the first cover body 300 on the second cover body 400, and install a sealing ring 205 on each of the two suction switches 204, and then install them respectively on the two channels formed on both sides after the first cover body 300 and the second cover body 400 are assembled. At this time, a top of an intracavitary endoscope cleaning and smoke exhaust device is formed.

[0060] In the second step, the second air-blocking valve 501 is sleeved on a protrusion at the lower end of the bottom of the inner core tube 500, the locking fixing seat 200 is assembled with the outer sleeve 100, and the inner core tube 500 with the second air-blocking valve 501 is put into the locking fixing seat 200. The outer wall of the top of the inner core tube 500 is provided with a protrusion, and the inner wall of the locking fixing seat 200 is provided with a groove, and the two match each other to ensure that the position of the inner core tube 500 in the outer sleeve 100 will not move.

[0061] In the third step, the first cover body 300 and the second cover body 400 are installed on the locking and fixing base 200 .

[0062] The fourth step is to put the protective cover 700 on the outside of the device. The protective cover 700 has great elasticity, so although its opening is very small, it can still be put on from the largest part of the top of the device, and then tightly wrap the device to completely cover the seams of the assembly part of the device, which greatly prevents bacteria from entering the inside of the device from the interface.

[0063] After the puncture cone fixing cover 601 is installed on the top of the puncture cone 600, it is convenient for people to hold it, and after the assembly is completed, it can be pushed in from the top opening of the device to complete the puncture and other tasks.

[0064] After the puncture work is completed, the camera can be replaced and pushed into the device to complete the subsequent work.

[0065] If the camera is contaminated, pull it back and enter the second air blocking valve 501. At this time, open the water inlet and suction switch 204. After the water flows into the outer sleeve 100, close the water inlet and suction switch 204. At this time, open the water outlet and suction switch 204. Under the action of suction, the water flows into the inner core tube 500 from the water inlet hole at the lower end of the inner core tube 500, and then flows out from the water outlet hole. The water flow can also take away the contaminants on the camera. If the cleaning is not thorough once, repeat the above operation to thoroughly clean the contaminants on the camera. After cleaning, subsequent surgical work can be carried out.

[0066] If smoke is generated in the surgical area during surgery, the camera only needs to be aimed at the smoke and the air valve switch 203 is turned on. The smoke will then enter the outer sleeve 100 from the second air blocking valve 501 and then be drawn out from the outer sleeve 100, completing the smoke exhaust work.

[0067] Embodiment 2: First, place the first air blocking valve 202 on the inner circle of the second cover body 400, the outer circle diameter of the first air blocking valve 202 is larger than the inner circle diameter of the second cover body 400, and then place the self-adjusting sealing cap 201 on the first air blocking valve 202, and then install the first cover body 300 on the second cover body 400, and install a sealing ring 205 on each of the two suction switches 204, and then install them respectively on the two channels formed on both sides after the first cover body 300 and the second cover body 400 are assembled. At this time, a top of an intracavitary endoscope cleaning and smoke exhaust device is formed.

[0068] In the second step, the second air-blocking valve 501 is sleeved on a protrusion at the lower end of the bottom of the inner core tube 500, the locking fixing seat 200 is assembled with the outer sleeve 100, and the inner core tube 500 with the second air-blocking valve 501 is put into the locking fixing seat 200. The outer wall of the top of the inner core tube 500 is provided with a protrusion, and the inner wall of the locking fixing seat 200 is provided with a groove, and the two match each other to ensure that the position of the inner core tube 500 in the outer sleeve 100 will not move.

[0069] In the third step, the first cover body 300 and the second cover body 400 are installed on the locking and fixing base 200 .

[0070] The fourth step is to put the protective cover 700 on the outside of the device. The protective cover 700 has great elasticity, so although its opening is very small, it can still be put on from the largest part of the top of the device, and then tightly wrap the device to completely cover the seams of the assembly part of the device, which greatly prevents bacteria from entering the inside of the device from the interface.

[0071] After the puncture cone fixing cover 601 is installed on the top of the puncture cone 600, it is convenient for people to hold it, and after the assembly is completed, it can be pushed in from the top opening of the device to complete the puncture and other tasks.

[0072] After the puncture work is completed, the camera can be replaced and pushed into the device to complete the subsequent work.

[0073] If the camera is contaminated, it is pulled back and enters the second air blocking valve 501. At this time, the water inlet and suction switch 204 is opened. After the water flows into the outer sleeve 100, the water inlet and suction switch 204 is closed. At this time, the water outlet and suction switch 204 is opened, and the water flows in from the water inlet groove, and under the action of suction, it flows into the inner core tube 500 from the water inlet hole at the lower end of the inner core tube 500, and then flows out from the water outlet hole, enters the water outlet groove, and is finally discharged from the water outlet to the outside of the device. The water flow can also take away the contaminants on the camera. If the cleaning is not thorough once, repeat the above operation to thoroughly clean the contaminants on the camera. After cleaning, subsequent surgical work can be carried out.

[0074] If smoke is generated in the surgical area during the operation, it is only necessary to aim the camera at the smoke part and turn on the air valve switch 203. The smoke will enter the inner core tube 500 from the second air blocking valve 501, and be sucked into the smoke guide groove set on the outer wall of the inner core tube 500 from the smoke guide groove on the smoke guide protrusion at the lower end of the inner core tube 500, and finally be sucked out. After completion, the field of vision is clear and subsequent surgical work can be carried out.
