Description

Technical Field

[0001] This invention relates to the field of endoscopy technology, and more particularly to a portable enterostomy endoscope. Background Technology

[0002] An enterostomy is an artificial opening made in the abdominal wall by a surgeon to treat certain intestinal diseases (such as rectal cancer, ulcerative colitis, etc.), through which a section of the intestine is pulled out of the opening, turned inside out, and sutured to the abdominal wall, thus forming an enterostomy.

[0003] For patients undergoing enterostomy, it is necessary to regularly check the recovery of the required areas during the subsequent treatment process. An endoscope needs to be inserted into the enterostomy to reach the required areas for sampling. The removed polyps are then tested to achieve the goal of combining diagnosis and treatment.

[0004] Currently, there is no dedicated enterostomy endoscope in clinical practice. Cystoscopy or flexible ureteroscopy are generally used as substitutes. However, cystoscopy or flexible ureteroscopy cannot meet the examination purpose, as the field of vision is not clear enough and it is inconvenient to locate the ureteral orifice. Therefore, in order to solve clinical problems, this device provides a portable enterostomy endoscope. Summary of the Invention

[0005] This invention provides a portable enterostomy endoscope to solve the aforementioned technical problems.

[0006] This invention employs the following technical solution: It includes an endoscope chamber, a first driving mechanism, a second driving mechanism, a mating mechanism, an endoscope, and a dilation mechanism. The endoscope chamber includes a handheld cavity and an insertion cavity, which are connected and hollow inside. The first driving mechanism drives the mating mechanism to extend and retract within the insertion cavity and is located inside the handheld cavity. The second driving mechanism drives the mating mechanism to rotate within the insertion cavity and is located at the point where the handheld cavity and the insertion cavity are connected. The mating mechanism is connected to the first driving mechanism and the second driving mechanism. The mechanism is connected and located inside the endoscope chamber. The endoscope is positioned at one end of the mating mechanism and close to the dilation mechanism. The endoscope's proximal end is equipped with a clamping mechanism for holding objects. The endoscope's interior is equipped with a drive device for driving the clamping mechanism. The endoscope chamber's exterior is equipped with an opening knob for controlling the drive device. The dilation mechanism is positioned at the proximal end of the insertion cavity. Both the proximal ends of the dilation mechanism and the proximal ends of the endoscope are equipped with camera probes. The endoscope chamber is connected to a display, and the display and the corresponding camera probes are electrically connected.

[0007] Furthermore, the first driving mechanism includes a first driving housing, a first driving motor, a first main helical gear, a first driven helical gear, a bracket, a driving shaft, and a turntable.

One end of the second connecting rod is rotatably connected to the other end of the first connecting rod. The other end of the second connecting rod is sleeved on the connecting shaft and is rotatably connected.

[0010] Furthermore, the expansion mechanism includes an expansion component and a stretching component. The expansion component is disposed at the head end of the rotating cylinder, and the stretching component is disposed outside the endoscope. The expansion component is driven by the stretching component. The expansion component includes an arc-shaped block, a first semicircular block, a second semicircular block, a first shaft, a second shaft, a first gear, and a second gear. The arc-shaped block is disposed at the head end of the rotating cylinder. The first shaft and the second shaft are symmetrically disposed on both sides of the arc-shaped block.

[0013] Furthermore, the display is electrically connected to the first drive knob, the second drive knob, and the turn-on knob. The display has a removable and rechargeable battery inside. The display has a knob for controlling the start of the corresponding camera probe and a knob for turning the display on. The display has connection holes adapted to the endoscope image processing device.

[0014] Furthermore, it also includes an endoscope cable, an instrument insertion port, and an infusion port. The outside of the insertion cavity is provided with a hole for insertion into the endoscope cable. The end of the endoscope cable can be inserted into the hole for connection and is electrically connected to the display after connection. The instrument insertion port is located outside the head end of the endoscope cable. The infusion port is located on the instrument insertion port. The head end of the endoscope cable is flexible and the same as the head end of a traditional endoscope. The head end of the endoscope cable is provided with an endoscopic camera probe and an instrument channel.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, it allows for regular observation and biopsy of the required sites for patients undergoing enterostomy. During observation and sampling, the semi-circular shape of the dilation mechanism's tip guides the insertion into the required sites, minimizing pain during insertion. Simultaneously, the camera probe on the dilation mechanism transmits video to a monitor to view the path and status during insertion. Therefore, the clamping mechanism on the endoscope remains inside the dilation mechanism throughout insertion and subsequent withdrawal. This clamping mechanism, with its clamping and cutting functions, ensures that it does not contact the insertion or withdrawal points of the enterostomy, preventing harm to the patient and reducing pain during observation and sampling.

[0017] This device employs two modes: observation mode and sampling mode. These two modes can also work together.

[0018] This device is similar in shape to a traditional medical gun, making it easy to handle and operate, and thus quite convenient.

[0019] Secondly, since the required observation location for each patient's enterostomy is different, the required insertion position will also be different. When the required observation location for the patient's enterostomy is deep, and the size of the endoscope chamber is insufficient for the camera probe on the dilation mechanism to reach the required observation location, medical staff can first hold the handpiece and insert the camera probe on the dilation mechanism towards the required observation location of the enterostomy. After the endoscope chamber has driven the camera probe on the dilation mechanism into place, the two stretching blocks are pushed and pulled separately, thereby causing the two stretching racks to move symmetrically outward. The symmetrical outward rotation of the two stretching racks causes the first gear and the second gear to rotate symmetrically in the direction of the corresponding stretching blocks. The rotation of the first gear and the second gear will cause the first semicircular block and the second semicircular block to rotate in the direction of the corresponding stretching block, thereby causing the first semicircular block and the second semicircular block to open. At this time, medical staff can press the start / pause button in the first drive knob outside the first drive housing to start the first drive motor. A drive motor rotates, causing the first main helical gear on its output end to rotate. This rotation drives the first driven helical gear, which in turn drives the drive shaft to rotate on the support. The drive shaft's rotation causes the turntable to rotate, which in turn causes the mating shaft to rotate eccentrically on the turntable. This eccentric rotation of the mating shaft then moves the first and second connecting rods, causing the endoscope to slide and extend within the rotating cylinder towards the expansion mechanism. This allows the endoscope's tip to reach the desired observation area on the patient. Medical personnel can then observe the patient's area using the camera probe on the endoscope. Since the camera probe's field of view is currently limited, a second drive motor is activated to rotate the rotating cylinder. This rotation also causes the endoscope to rotate, resulting in a 360-degree rotation of the camera probe on the endoscope. This allows medical personnel to observe the patient's area from all angles on the monitor, facilitating accurate diagnosis and subsequent treatment.

[0020] Thirdly, when performing a biopsy on a patient undergoing enterostomy, medical staff first insert the dilation mechanism into the desired sampling location. After the dilation mechanism is in place, the first and second semicircular blocks within it are opened. Then, the second drive motor rotates the clamping mechanism on the endoscope to the required angle to align with the biopsy polyp. Next, the first drive motor moves the clamping mechanism on the endoscope towards the desired polyp location, positioning it precisely at the desired clamping positions on both sides of the polyp. At this point, pressing the external opening knob of the endoscope chamber activates the drive system, causing the clamping mechanism to clamp and remove the polyp. During the process, video can be transmitted in real time to the monitor via the camera probes at the head of the dilation mechanism and the head of the endoscope. This allows medical staff to observe the path and internal condition in real time, facilitating their operation. After the clamping mechanism grasps and removes the severed polyp, the first drive motor drives the endoscope back into the dilation mechanism, closing the first and second semicircular blocks in the dilation mechanism. Then, the endoscope chamber is removed from the patient's enterostomy, thus achieving the removal of the required polyp for testing. At the same time, the risk of the polyp falling into the patient's enterostomy is avoided during the removal process because when the clamping mechanism moves back to its original position, it is removed by the first and second semicircular blocks in a wrapped state.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] This invention provides a portable enterostomy endoscope, comprising an endoscope chamber 1, a first driving mechanism 2, a second driving mechanism 3, a mating mechanism 4, an endoscope 5, and a dilation mechanism 6. The endoscope chamber 1 includes a handheld cavity 11 and an insertion cavity 12, which are connected and hollow. The first driving mechanism 2 drives the mating mechanism 4 to extend and retract within the insertion cavity 12 and is located inside the handheld cavity 11. The second driving mechanism 3 drives the mating mechanism 4 to rotate within the insertion cavity 12 and is located at the point where the handheld cavity 11 and the insertion cavity 12 are connected. The mating mechanism 4 is connected to the first driving mechanism 6. The actuator 2 and the second drive mechanism 3 are connected and located inside the endoscope chamber 1. The endoscope 5 is disposed at one end of the mating mechanism 4 and at one end close to the expansion mechanism 6. The end of the endoscope 5 is provided with a clamping mechanism 7 for clamping an object. The endoscope 5 is provided with a drive device for driving the clamping mechanism 7. The endoscope chamber 1 is provided with an opening knob 71 for controlling the drive device. The expansion mechanism 6 is disposed at the end of the insertion cavity 12. Both the end of the expansion mechanism 6 and the end of the endoscope 5 are provided with camera probes 8. The endoscope chamber 1 is connected to a display 9. The display 9 and the corresponding camera probe 8 are electrically connected.

[0041] The display 9 in this device is equipped with a host that is compatible with the display 9 required for traditional endoscopes and can be connected. After the host is started and the host and the display 9 are electrically connected, the display 9 can be operated.

[0042] This device allows for regular observation and biopsy of the required sites in patients undergoing enterostomy treatment. During observation and sampling, the dilation mechanism 6, with its semi-circular end, extends into the required site, minimizing pain upon contact with the patient. Simultaneously, to facilitate insertion, the camera probe 8 on the dilation mechanism 6 transmits video to the display 9, allowing for monitoring of the path and status. Therefore, the clamping mechanism 7 on the endoscope 5 remains inside the dilation mechanism 6 throughout insertion and subsequent withdrawal. This clamping mechanism 7, with its clamping and cutting functions, ensures that it does not contact the stoma insertion and withdrawal sites, preventing harm and reducing pain during observation and sampling.

[0043] This device employs two modes: observation mode and sampling mode, and these two modes can also work together.

[0044] This device is similar in shape to a traditional medical gun, making it easy to handle and operate, and thus quite convenient.

[0045] Preferably, the first drive mechanism 2 includes a first drive housing 21, a first drive motor 22, a first main helical gear 23, a first driven helical gear 24, a bracket 25, a drive shaft 26, and a turntable 27. The first drive housing 21 is disposed on the outer wall of the hand-held cavity 11. The first drive motor 22 is disposed inside the first drive housing 21 and its output end passes through the outer wall of the hand-held cavity 11 and is located inside the hand-held cavity 11. The first main helical gear 23 is disposed on the output end of the first drive motor 22. The bracket 25 is disposed on the inner wall of the hand-held cavity 11. The drive shaft 26 is rotatably connected to the shaft 51 on the bracket 25. The first driven helical gear 24 is disposed at the lower end of the drive shaft 26 and is in a meshing state with the first main helical gear 23. The turntable 27 is disposed at the upper end of the drive shaft 26.

[0046] The operation of the first drive motor 22 drives the first main helical gear 23 on the output end of the first drive motor 22 to rotate. The rotation of the first main helical gear 23 drives the first driven helical gear 24 to rotate. The rotation of the first driven helical gear 24 drives the drive shaft 26 to rotate on the bracket 25. The rotation of the drive shaft 26 drives the turntable 27 to rotate. The rotation of the turntable 27 drives the mating shaft 41 to rotate eccentrically on the turntable 27. The eccentric rotation of the mating shaft 41 drives the first connecting rod 42 and the second connecting rod 43 to move, thereby driving the endoscope 5 to slide and extend inside the rotating cylinder 35.

[0047] Preferably, the second drive mechanism 3 includes a second drive housing 31, a second drive motor 32, a second main helical gear 33, a second driven helical gear 34, and a rotating drum 35. The second drive housing 31 is disposed at the upper end of the handheld cavity 11. The second drive motor 32 is disposed inside the second drive housing 31 and its output end passes through the upper end of the handheld cavity 11 and is located inside the handheld cavity 11. The second main helical gear 33 is disposed on the output end of the second drive motor 32. The rotating drum 35 is rotatably connected to the insertion cavity 12. The second driven helical gear 34 is disposed at the end of the rotating drum 35 and is meshed with the second main helical gear 33.

[0048] The second drive motor 32 starts running and drives the second main helical gear 33 on the output end of the second drive motor 32 to rotate. The rotation of the second main helical gear 33 drives the second driven helical gear 34 to rotate. The rotation of the second driven helical gear 34 drives the rotating cylinder 35 to rotate inside the endoscope 5 cavity. The rotation of the rotating cylinder 35 drives the expansion mechanism 6 to rotate, thereby driving the camera probe 8 on the expansion mechanism 6 to rotate 360 ​​degrees. Simultaneously, it also drives the endoscope 5 to rotate, thus achieving the goal of driving the camera probe 8 on the endoscope 5 to rotate 360 ​​degrees.

[0049] Preferably, the mating mechanism 4 includes a mating shaft 41, a first connecting rod 42, and a second connecting rod 43. The endoscope 5 is disposed inside the rotating cylinder 35 and is in a left-right sliding fit. A connecting shaft 51 is provided inside the end of the endoscope 5 facing the turntable 27. The mating shaft 41 is eccentrically disposed on the upper end of the turntable 27. One end of the first connecting rod 42 is sleeved on the mating shaft 41 and is rotatably connected. One end of the second connecting rod 43 is rotatably connected to the other end of the first connecting rod 42. The other end of the second connecting rod 43 is sleeved on the connecting shaft 51 and is rotatably connected.

[0050] Preferably, the expansion mechanism 6 includes an expansion component 61 and a stretching component 62. The expansion component 61 is disposed at the head end of the rotating cylinder 35, and the stretching component 62 is disposed outside the endoscope 5. The expansion component 61 is driven to stretch by the stretching component 62. The expansion component 61 includes an arc-shaped block 611, a first semicircular block 612, a second semicircular block 613, a first shaft 614, a second shaft 615, a first gear 616, and a second gear 617. The arc-shaped block 611 is disposed at the head end of the rotating cylinder 35. The first shaft 614 and the second shaft 615 are symmetrically disposed on both sides of the arc-shaped block 611. One end of the first semicircular block 612 is fixedly sleeved on the first shaft 614, and the other end is rotatably sleeved on the second shaft 615. One end of the second semicircular block 613 is fixedly sleeved on the second shaft 615, and the other end is rotatably sleeved on the first shaft 614. The first gear 616 is fixedly sleeved on the first shaft 614, and the second shaft 615 is fixedly sleeved on the second gear 617.

[0051] When the first semicircular block 612 and the second semicircular block 613 are in the closed state, they form a semicircular arc. Therefore, when medical staff hold the hand cavity 11, they can insert the semicircular arc-shaped head of the expansion mechanism 6 into the required area of ​​the patient undergoing enterostomy treatment. This avoids causing significant pain when the device contacts the patient's area during insertion. At the same time, to facilitate insertion into the required area, the video transmitted by the camera probe 8 on the expansion mechanism 6 is displayed on the monitor 9 to view the required path and situation. Therefore, when the device enters the required position and is subsequently extended, the clamping mechanism 7 on the endoscope 5 is always inside the expansion mechanism 6. The clamping mechanism 7 is a device with clamping and cutting functions. Thus, during insertion into the required area of ​​the patient, the clamping mechanism 7 will not come into contact with the patient's enterostomy insertion and extension areas, thereby preventing harm to the patient and reducing the pain experienced by the patient during observation and sampling. The principle of the clamping mechanism 7 in this device is the same as that of existing medical clamping and cutting devices.

[0052] When medical staff insert this device into the required area of ​​the patient, they can apply a soluble lubricating solvent to the semi-circular arc formed when the first semi-circular block 612 and the second semi-circular block 613 are in the closed state to facilitate better insertion into the required area of ​​the patient.

[0053] Preferably, the stretching assembly 62 includes a stretching rack 621, a stretching member 622, and a stretching block 623. Two symmetrical sliding grooves 13 are provided on the outer side of the endoscope chamber 1. Two stretching racks 621 are provided, each meshing with a first gear 616 and a second gear 617 respectively. Two stretching blocks 623 are provided, each located within a corresponding sliding groove 13 and in a slidable and lockable state. The two stretching blocks 623 are staggered. Two stretching members 622 are provided, one end of each member connected to a corresponding stretching rack 621, and the other end connected to a corresponding stretching block 623. The principle of the two stretching blocks 623 and their corresponding sliding grooves 13 is similar to that of a push knob and sliding groove 13 on a traditional utility knife. The principles are the same, and all can achieve sliding and locking states on the slide groove 13. The first drive housing 21 is provided with a first drive knob 211 for controlling the operation of the first drive motor 22, and the second drive housing 31 is provided with a second drive knob 311 for controlling the operation of the second drive motor 32. The first drive knob 211, the second drive knob 311 and the opening knob 71 have the same structure. The first drive knob 211 includes a start / pause button. The display 9 is electrically connected to the first drive knob 211, the second drive knob 311 and the opening knob 71. The display 9 is provided with a removable and rechargeable battery. The display 9 is provided with a knob for controlling the start of the corresponding camera probe 8 and a knob for opening the display 9. The display 9 is provided with a connection hole for the endoscope image processing device.

[0054] During operation, after the endoscope image processing device is connected to the connection hole on the display 9, it can control the device to perform a series of operations such as recording video, taking pictures, contouring, brightness adjustment, electronic zoom, image freezing, gain adjustment, and white balance.

[0055] Preferably, it also includes an endoscope 10, an instrument insertion port 101, and an infusion port 102. The outside of the insertion cavity 12 is provided with a hole 103 for insertion into the endoscope 10. The end of the endoscope 10 can be inserted into the hole 103 for connection and is electrically connected to the display 9 after connection. The instrument insertion port 101 is located outside the head end of the endoscope 10. The infusion port 102 is located on the instrument insertion port 101. The head end of the endoscope 10 is provided with an endoscope camera probe. The head end of the endoscope 10 is flexible and the same as the head end of a traditional endoscope. The head end of the endoscope 10 is provided with an endoscope camera probe 104 and an instrument channel 105.

[0056] If it is necessary to remove foreign objects or take samples during patient treatment and observation, the end of the endoscope 10 can be connected to the external opening 103 of the insertion cavity 12. After connection, medical staff can insert the endoscope 10 from the first end to the desired patient treatment position for observation. During other treatment operations, such as foreign object removal or sampling, after inserting the endoscope 10 from the first end to the desired patient treatment position, the necessary auxiliary equipment can be inserted through the instrument insertion port 101 and extended through the instrument channel 105 to the desired treatment position for operation. During the operation, the first end of the endoscope 10... The endoscope camera probe 104 at the end can provide medical staff with accurate treatment images at any time. If it is necessary to perform other liquid or gas operations such as flushing the required area of ​​the patient, the liquid or gas inlet 102 can be introduced and flow out from the instrument channel 105 to the required treatment location. At the same time, the endoscope camera probe 104 at the head end of the endoscope body 10 is always in the detection state, providing medical staff with accurate images. The internal condition can be observed through the display screen 9, and the endoscope image processing device can enable medical staff to operate and adjust the treatment according to the specific treatment situation, which improves the quality of treatment for patients and diversifies the treatment methods.

[0057] When performing regular observations on patients undergoing enterostomy, medical staff first turn on the monitor 9, then turn on the camera probe 8 on the dilation mechanism 6, and check the camera image on the monitor 9 to ensure it is normal. The monitor 9 is then placed in an easily observable position. The medical staff holds the handpiece 11 and inserts the camera probe 8 of the dilation mechanism 6 towards the desired location on the enterostomy patient. The medical staff then slowly inserts the dilation mechanism 6 into the enterostomy, stopping once the desired observation site is reached. During the insertion of the dilation mechanism 6, the path can be observed through the camera probe 8 to avoid causing significant pain or harm to the patient. At this time, the medical staff can observe the condition of the desired area on the patient through the camera probe 8. Because the camera probe 8 currently... Due to the limited range, medical staff can start the second drive motor 32 by pressing the start / pause button in the second drive knob 311 outside the second drive housing 31. The start-up of the second drive motor 32 drives the second main helical gear 33 on the output end of the second drive motor 32 to rotate. The rotation of the second main helical gear 33 drives the second driven helical gear 34 to rotate. The rotation of the second driven helical gear 34 drives the rotating cylinder 35 to rotate inside the endoscope 5 cavity. The rotation of the rotating cylinder 35 drives the dilation mechanism 6 to rotate, thereby driving the camera probe 8 on the dilation mechanism 6 to rotate 360 ​​degrees. Thus, medical staff can observe the condition of the patient's required parts from all angles on the display 9, which is convenient for medical staff to accurately judge the patient's condition and carry out further treatment.

[0058] Because the required observation location of each patient's enterostomy is different, the required insertion position will also be different. When the required observation location of the patient's enterostomy is deep, and the size of the endoscope chamber 1 is insufficient for the camera probe 8 on the dilation mechanism 6 to reach the required observation location, the medical staff can first hold the handheld cavity 11 and insert the camera probe 8 on the dilation mechanism 6 toward the required observation location of the enterostomy. After the endoscope chamber 1 has driven the camera probe 8 on the dilation mechanism 6 into place, the two tension blocks 623 are pushed and pulled separately, thereby causing the two tension racks 621 to move symmetrically outward. The symmetrical outward rotation of the two tension racks 621 causes the first gear 616 and the second gear 617 to rotate symmetrically toward the corresponding tension block 623. The rotation of the first gear 616 and the second gear 617 will cause the first semicircular block 612 and the second semicircular block 613 to rotate toward the corresponding tension block 623, thereby causing the first semicircular block 612 and the second semicircular block 613 to open. Figure 1 and Figure 2 As shown, at this time, medical staff can start the first drive motor 22 by pressing the start / pause button in the first drive knob 211 outside the first drive housing 21. The operation of the first drive motor 22 drives the first main helical gear 23 on the output end of the first drive motor 22 to rotate. The rotation of the first main helical gear 23 drives the first driven helical gear 24 to rotate. The rotation of the first driven helical gear 24 drives the drive shaft 26 to rotate on the bracket 25. The rotation of the drive shaft 26 drives the turntable 27 to rotate. The rotation of the turntable 27 drives the mating shaft 41 to rotate eccentrically on the turntable 27. The eccentric rotation of the mating shaft 41 drives the first connecting rod 42 and the second connecting rod 43 to move, thereby driving the endoscope 5 to rotate. The inside of the cylinder 35 slides out of the expansion mechanism 6, allowing the tip of the endoscope 5 to move to the desired observation area of ​​the patient. At this time, medical staff can observe the condition of the desired area of ​​the patient through the camera probe 8 on the endoscope 5. Since the imaging range of the camera probe 8 is currently limited, the second drive motor 32 is started to drive the rotating cylinder 35 to rotate. The rotation of the rotating cylinder 35 will also drive the endoscope 5 to rotate, thereby driving the camera probe 8 on the endoscope 5 to rotate 360 ​​degrees. Thus, medical staff can observe the condition of the desired area of ​​the patient from all angles according to the display 9, which is convenient for medical staff to accurately judge the patient's condition and carry out further treatment.

[0059] When performing a biopsy on a patient undergoing enterostomy, medical staff first insert the dilation mechanism 6 into the desired sampling location. After the dilation mechanism 6 is in place, the first semicircular block 612 and the second semicircular block 613 within it are opened. Then, the second drive motor 32 rotates the clamping mechanism 7 on the endoscope 5 to the desired angle to align with the biopsy polyp. Next, the first drive motor 22 moves the clamping mechanism 7 on the endoscope 5 towards the desired polyp location, positioning it precisely at the desired clamping positions on both sides of the polyp. At this point, pressing the external opening knob 71 of the endoscope chamber 1 activates the drive system, causing the clamping mechanism 7 to clamp and remove the desired polyp. During this process… Both the expansion mechanism 6 and the endoscope 5 can transmit video in real time to the display 9 through the camera probe 8 on the head end of the expansion mechanism 6 and the head end of the endoscope 5. This allows medical staff to observe the path and internal condition in real time through the display 9, which is convenient for medical staff to operate. After the clamping mechanism 7 clamps and removes the polyp, the first drive motor 22 drives the endoscope 5 back into the expansion mechanism 6 and closes the first semicircular block 612 and the second semicircular block 613 in the expansion mechanism 6. Then, the endoscope chamber 1 is removed from the patient's enterostomy, thus realizing the removal of the required polyp for testing. At the same time, the risk of the polyp falling into the patient's enterostomy is avoided during the removal process, because when the polyp is removed, the clamping mechanism 7 moves back to its original position and is removed by the first semicircular block 612 and the second semicircular block 613 in a wrapped state.

[0060] After the clamping mechanism 7 clamps and removes the polyp for biopsy, the first semicircular block 612 and the second semicircular block 613 are opened. At the same time, the first drive mechanism 2 is activated to extend and retract the endoscope 5 so that the first semicircular block 612 and the second semicircular block 613 are outside it. The medical staff can hold the hand cavity 11 and operate the clamping mechanism 7 to place the polyp for biopsy into the sterile biopsy bottle to be used.

[0061] After the clamping mechanism 7 clamps and removes the polyp used for biopsy, when it is necessary to perform biopsy sampling on other patients, the first drive mechanism 2 can be activated to extend the endoscope 5 to extend the first semicircular block 612 and the second semicircular block 613 to its outside, so as to facilitate the cleaning and disinfection of the endoscope 5 and the clamping mechanism 7, and avoid cross-infection with other patients.

[0062] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
