Description

Technical Field

[0001] The present invention relates to the technical field of living tissue sampling, in particular to a living tissue sampling device for pathology department. Background Art

[0002] Biopsy forceps is a medical tool used to bite and sample the lesions inside the human body. It is generally used in conjunction with an endoscope. During endoscopic examination, when a pathological examination of the lesion is required, the biopsy forceps is sent into the patient's body through the endoscopic forceps channel to clamp and cut the tissue of the lesion. The sampling with biopsy forceps has the advantages of less pain and less trauma during the whole process. Finally, the sample taken by the biopsy forceps is sent to the pathology department for testing. The main sampling areas are esophagus, stomach, duodenum, bile and pancreatic duct, cervix, etc.

[0003] However, during use, the biopsy forceps is inserted deep into the pathological area of the cervix where sampling is required. After the biopsy forceps reaches the pathological area of the cervix, a small part of the pathological sample is clamped in the pathological area by controlling the clamping switch of the biopsy forceps. Then the clamping state of the biopsy forceps is maintained and gradually taken out from the patient's pathological area. The cervical case area is often complex. When facing different acetic acid white areas with more serious lesions, the staff takes at least two and at most four targeted biopsies. Each time a sample is taken from the cervix, a sample is taken and then the patient's cervical case position is re-entered. After multiple samplings, the samples are sent to the pathology department for examination. In this state, on the one hand, it will affect the normal sampling progress. On the other hand, repeated entry into the patient's cervix will increase the patient's maladaptability and reduce the patient's comfort during the sampling process. Summary of the Invention

After multiple samplings, the samples are sent to the pathology department for examination. In this state, on the one hand, the normal sampling progress is affected, and on the other hand, repeated entry into the patient's cervix will increase the patient's discomfort and reduce the patient's comfort during the sampling process.

[0008] Optionally, a second adapting groove is formed at one end of the movable tube close to the second traction column, a clamping portion is fixedly connected to the inner wall of the second adapting groove, and a limiting ring is fixedly connected to the outer surface of the middle portion of the movable tube.

[0009] Optionally, an end portion of the movable tube close to the second adapting chute is fixedly connected to a spring piece, and the other end of the movable tube away from the spring piece is fixedly connected to a second barb.

[0010] Optionally, the inner cavity of the biopsy forceps is fixedly connected to a fixing plate, the outer surface of the fixing plate is installed with a sliding sheet, and the outer surface of the sliding sheet is fixedly connected to a connecting sheet.

[0011] Optionally, a snap plate is fixedly connected to the side of the movable plate, a guide column is fixedly connected to the side of the movable plate, a first snap groove is opened on the outer surface of the biopsy forceps near the snap plate, and a weakened portion is opened in the middle of the snap plate.

[0012] Optionally, the first barbs are distributed in a circular array on the outer surface of the second traction column in a certain number, the size of the first barbs is consistent with the size of the piston groove, and the lightweight groove, the first adaptation groove and the second clamping groove are all distributed in a circular array on the outer surface of the second clamping groove.

[0013] Optionally, the second adapting groove is adapted to the first adapting groove, the clamping portion is adapted to the second clamping groove, and the outer surface of the limiting ring is fitted to the middle of the movable cap.

[0014] Optionally, the second barbs are distributed in a circular array at the bottom end of the movable tube, one end of the spring is fixedly connected to the top of the movable tube, and the other end is fixedly connected to the middle of the movable cap.

[0015] Optionally, both sides of the fixing plate are fixedly connected to the inner cavity in the middle of the biopsy forceps, the inner surface of the sliding sheet is slidably connected to the outer surface of the fixing plate, one end of the connecting piece is fixedly connected to the outer surface of the sliding sheet, and the other end is fixedly connected to the middle of the first traction column.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up an auxiliary collection component, when the staff uses the biopsy forceps to operate the sampling, after sampling a cervical pathological sample, there is no need to remove the biopsy forceps from the patient's cervix and then collect the sample and then re-enter the patient's cervix. In this state, on the one hand, the uncertainty risk that may be caused by the biopsy forceps repeatedly entering the patient's cervix can be reduced, and on the other hand, the adaptability of the biopsy forceps to the patient can be improved, ensuring the patient's body's ability to gradually adapt to the biopsy forceps, and improving the comfort during the sampling process.

[0018] By setting the snap plate, the guide column and the first snap groove, after the biopsy forceps is sent to the pathological position of the patient's cervix, the middle finger presses the movable plate. Under the pressing action, the continued displacement of the movable plate will make the open end of the snap plate approach the first snap groove. When the position of the open end of the snap plate is snapped into the inside of the first snap groove, it indicates that the first snap groove has completed the positioning of the snap plate, and then the positioning of the movable plate is completed, so that the first traction column fixed on the upper left end of the movable plate is also pulled to the right, thereby changing the position of the first traction column in the inner cavity of the biopsy forceps, making it easier to prepare for the next process and improving the linkage of the structure and the adaptability of the device as a whole.

[0019] By providing the first barb, the piston groove and the movable cap, the movable cap is clamped inside the piston groove, and the movable cap is clamped and installed in the piston groove at the end of the first barb before use. After the clamping is stable, the second traction column changes its position as the first traction column moves, and the entire second traction column is fixed in the first traction column on the left, that is, the position extending toward the middle outer cavity of the biopsy forceps. The diameter of the curved first barb plus the diameter of the second traction column is exactly consistent with the diameter of the first traction column. In this way, when the second traction column is extended and retracted back and forth from the middle inner cavity of the biopsy forceps, the friction of the first traction column and the second traction column as a whole is reduced, so that when the movable plate is pressed, it will not be time-consuming and laborious due to excessive friction between the other components, which helps to improve the overall working efficiency and convenience of the biopsy forceps.

[0020] By providing the second adapting groove, the clamping part, the limiting ring, the spring piece and the second barb, the movable tube can be well brought into contact with the sampling clamp component of the biopsy forceps, thereby falling into the slot on the sampling clamp component of the biopsy forceps. The process is repeated until the location of the lesion inside the patient's cervix is sampled and the biopsy forceps can be removed from the patient's body, thereby improving the sampling efficiency and the uniformity and centralization of the collection of pathological samples, which is conducive to the organization and classification of pathological samples after the sampling operation is completed.

[0044] like Figures 1 to 14 As shown, an embodiment of the present invention provides a living tissue sampling device for pathology, including a biopsy forceps 1, wherein the inner cavity of the biopsy forceps 1 is installed with a first traction column 2, one end of the first traction column 2 is fixedly connected to a movable plate 3, the other end of the first traction column 2 is fixedly connected to a second traction column 4, and the end of the second traction column 4 is installed with a movable tube 5; an auxiliary collection component, the auxiliary collection component is used to centrally collect pathological sampling samples at different positions, the auxiliary collection component is connected to the biopsy forceps 1, the biopsy forceps 1 is an existing structure, and no further details are given. The special feature is that there are two clamping parts at the sampling point of the biopsy forceps 1, one of which has an end extending outward so that it will not be tightly closed after clamping, and there will be a certain gap between the clamping parts, the first traction column 2 runs through the middle of the biopsy forceps 1, and the middle position of the first traction column 2 is cut into two, and the two separated first traction columns 2 are grooved near the end. Half the thickness, so that the two first traction columns 2 can overlap when they are close to each other, the side of the movable plate 3 is fixed to one end of the first traction column 2, and a slotted hole is opened in the middle of the biopsy forceps 1, and the movable plate 3 is installed in the slotted hole in the middle of the biopsy forceps 1; the second traction column 4 is fixed to the other end of the first traction column 2, and the end of the movable tube 5 is installed in the middle of the second traction column 4. Through the above structure, when the staff uses the biopsy forceps 1 to operate the sampling, after sampling a cervical pathological sample, there is no need to remove the biopsy forceps 1 from the patient's cervix and then re-enter the patient's cervix after collecting the sample. In this state, on the one hand, the uncertainty risk that may be caused by the biopsy forceps 1 repeatedly entering the patient's cervix can be reduced, and on the other hand, the adaptability of the biopsy forceps 1 to the patient can be improved, ensuring the patient's body's gradual adaptation to the biopsy forceps 1, and improving the comfort during the sampling process.

[0045] like Figure 5 As shown, a snap plate 301 is fixedly connected to the side of the movable plate 3, and a guide column 302 is fixedly connected to the side of the movable plate 3. A first snap groove 303 is provided on the outer surface of the biopsy forceps 1 near the snap plate 301, and a weakened portion 304 is provided in the middle of the snap plate 301. The snap plate 301 is made of plastic, and one end is fixedly connected to the side of the lower part of the movable plate 3, and the other end is open. The guide column 302 is made of metal, and both ends are fixed in the slotted hole in the middle of the biopsy forceps 1, and the guide column 302 passes through the upper part of the movable plate 3, that is, the movable plate 3 can slide by the limit of the guide column 302, and the first snap groove 303 is provided next to the slotted hole in the middle of the biopsy forceps 1, which is consistent with the size of the open end of the snap plate 301, and the weakened portion 304 is provided at a position near the open end of the snap plate 301.

[0046] With the above structure, after the biopsy forceps 1 is sent to the pathological position of the patient's cervix and the normal clamping and sampling is completed, the middle finger starts to press the movable plate 3. Under the pressing action, the movable plate 3 will move horizontally from the left end to the right end along the trajectory of the guide column 302, as shown in FIG. Figure 5 As shown; during the displacement process, the ring finger and little finger can press the buckle plate 301 downward, so that when the movable plate 3 moves horizontally to the right end, the open end of the buckle plate 301 will not directly abut the edge of the slotted hole of the biopsy forceps 1, causing the movable plate 3 to be unable to move further. Then, when the movable plate 3 continues to move, the buckle plate 301 is pressed and abutted against the outer wall of the biopsy forceps 1 by the ring finger and little finger, rather than the edge of the open slot of the biopsy forceps 1. Then, the continued displacement of the movable plate 3 will cause the open end of the buckle plate 301 to approach the first clamping groove 303. When the position of the open end of the buckle plate 301 is clamped inside the first clamping groove 303, it indicates that the first clamping groove 303 has completed the limitation of the buckle plate 301, and then the movable plate 3 is limited, so that the first traction column 2 fixed at the upper left end of the movable plate 3 is also pulled to the right, thereby changing the position of the first traction column 2 in the inner cavity of the biopsy forceps 1, which is convenient for preparation for the next process and improves the linkage of the structure and the adaptability of the entire device.

[0047] like Figures 6 to 8 As shown, the inner cavity of the biopsy forceps 1 is fixedly connected to a fixing plate 201, a sliding piece 202 is installed on the outer surface of the fixing plate 201, and a connecting piece 203 is fixedly connected to the outer surface of the sliding piece 202. The fixing plate 201 is in the shape of a rectangular parallelepiped and is made of metal. The sides of the fixing plate 201 are fixed in the inner cavity of the biopsy forceps 1. The sliding piece 202 is made of rubber and is sleeved on the outer surface of the fixing plate 201. It has a certain thickness. One end of the connecting piece 203 is fixed to the position of the sliding piece 202 near the two ends of the fixing plate 201, and the other end is fixed to the middle position where the two first traction columns 2 are separated.

[0048] Through the above structure, after the moving plate 3 is pressed to move horizontally, the first traction column 2 fixedly connected to the upper left side thereof will be driven to move horizontally, such as Figure 8 As shown, at this time, the first traction column 2 on the right side will be pulled, and pulling the first traction column 2 will cause the connecting piece 203 fixedly connected to the slot at the end of the first traction column 2 to be pulled. Since the sliding piece 202 is a whole, when the sliding piece 202 is pulled to the right, as shown in FIG. Figure 7 As shown, the first traction column 2 on the left side will move to the left side with the connecting piece 203 and the first traction column 2 on the left side under the action of the sliding piece 202, that is, the first traction column 2 on the left side moves horizontally to the left, and the first traction column 2 on the right side moves horizontally to the right. In this state, the first traction column 2 on the left side extends to the left, that is, extends outward. This is an important step that needs to be completed. Since the sliding piece 202 is tightly attached to the outer surface of the fixed plate 201, and the gap between the fixed plate 201 and the first traction column 2 is slightly larger than the thickness of the sliding piece 202, the sliding piece 202 will not move in the opposite direction after being pulled, and the sliding piece 202 will not be wrinkled or folded, thereby effectively ensuring the movement of the first traction column 2, and at the same time it can also improve the process of the next step, thereby further improving the process of concentrated sampling of the pathological position of the patient's cervix.

[0049] like Figures 9 to 13 As shown, the auxiliary collection component includes a first barb 401 fixedly connected to the outer surface of the second traction column 4, a piston groove 402 is provided at the end of the second traction column 4 away from one end of the first traction column 2, a movable cap 403 is installed on the inner wall of the piston groove 402, a lightweight groove 404 is provided on the outer surface array of the middle part of the movable cap 403, a first adapting groove 405 is provided on the outer surface array of the middle and lower part of the movable cap 403, a second clamping groove 406 is provided on the outer surface array of the middle and lower part of the movable cap 403, the first barb 401 is made of plastic and is fixedly distributed in a circular array on the second traction column 4 The outer surface of the guide column 4 is bent in a direction opposite to the moving direction of the second traction column 4. The piston groove 402 is opened on the inner wall of the end of the second traction column 4, and the opening position is away from the fixed end of the first traction column 2 and the second traction column 4. The upper diameter of the movable cap 403 is larger than the lower diameter. The lightweight groove 404 is opened in the middle of the movable cap 403 and is distributed in a circular array. The first adapting groove 405 is opened on the outer surface of the lower part of the movable cap 403 and is distributed in a circular array. The second clamping groove 406 is opened on the outer surface of the lower part of the movable cap 403 and is distributed in a circular array.

[0050] Through the above structure, the movable cap 403 is clamped inside the piston groove 402. Before use, the movable cap 403 is clamped and installed inside the piston groove 402 at the end of the first barb 401. After the clamping is stable, the second traction column 4 changes its position as the first traction column 2 moves, and the entire second traction column 4 is fixed in the first traction column 2 on the left, that is, the position extending toward the middle outer cavity of the biopsy forceps 1. The diameter of the bending of the first barb 401 plus the diameter of the second traction column 4 is exactly consistent with the diameter of the first traction column 2. In this way, when the second traction column 4 is extended and retracted back and forth from the middle inner cavity of the biopsy forceps 1, the overall friction of the first traction column 2 and the second traction column 4 is reduced, so that when the movable plate 3 is pressed, it will not be time-consuming and laborious due to the excessive friction between the other components, which helps to improve the overall working efficiency and convenience of the biopsy forceps 1.

[0051] like Figure 14 As shown, the end of the movable tube 5 close to the second traction column 4 is provided with a second adapting groove 501, the inner wall of the second adapting groove 501 is fixedly connected with a clamping portion 502, the outer surface of the middle part of the movable tube 5 is fixedly connected with a limiting ring 503, the end of the movable tube 5 close to the second adapting groove 501 is fixedly connected with a spring piece 504, and the other end of the movable tube 5 away from the spring piece 504 is fixedly connected with a second barb 505, the second adapting groove 501 is opened at the top of the movable tube 5, and its shape and size are the same as those of the first adapting groove 4 05 are adapted to each other in shape and size, the clamping portion 502 is fixed on the inner wall of the second adapting groove 501, and the size of the clamping portion 502 is consistent with the size of the second clamping groove 406, the limiting ring 503 is fixed on the position of the middle outer surface of the movable tube 5, and the top of the limiting ring 503 is fitted in the middle position of the movable cap 403, the spring piece 504 is made of plastic, the bottom end is fixed on the top of the movable tube 5, and the top end is fixed in the middle position of the movable cap 403, and the second barbs 505 are distributed in a circular array on the outer surface of the bottom end of the movable tube 5.

[0052] Through the above structure, after the first traction column 2 is divided into two and displaced in opposite directions, the first traction column 2 extending outward will drive the second traction column 4 to move, and the second traction column 4 and the movable tube 5 are clamped by the second adapter groove 501 and the clamping portion 502, and the spring piece 504 is fixedly connected, so the entire movable tube 5 will be driven to move synchronously during displacement. During the movement, the open end of the movable tube 5 close to the second barb 505 will be gradually exposed from the inner cavity of the biopsy forceps 1, and will move along the direction of the clamping component in the biopsy forceps 1. Since the biopsy forceps 1 is in the sampling state at this time, and in order to ensure that the case sample does not fall into the patient's cervix, it is kept in a clamped and fixed state. At this time, pressing the movable plate 3 will drive the first The movement of the traction column 2, after the two separated first traction columns 2 move in different directions, causes the second traction column 4 and the movable tube 5 to be driven up. At this time, the movable tube 5 and the second barb 505 will approach the pathological sample and finally abut against it. At this time, the first traction column 2 is still moving, so the second traction column 4 and the movable tube 5 are also moving. Therefore, the spring piece 504 will be squeezed when abutting against each other, and at this time, the first adapting groove 405 and the second clamping groove 406 in the lower part of the movable cap 403 are exactly coincident with the second adapting groove 501 and the clamping portion 502, which can improve the synchronization of the second traction column 4 and the movable tube 5 when they move, and reduce the instability of the second traction column 4 and the movable tube 5 fixedly connected by the spring piece 504.

[0053] After the shrapnel 504 is squeezed, the movable tube 5 will move in the opposite direction, that is, close to the position of the second traction column 4, thereby forming an interactive force with the second traction column 4. At this time, the second barb 505 will be driven by the movable tube 5 to move in the direction close to the second traction column 4, and will also hook the pathological sample. Then, the control valve of the biopsy forceps 1 is slightly loosened, so that the sampling clamp component in the biopsy forceps 1 loses its fixation on the pathological sample, so that the second barb 505 in the movable tube 5 can hook and drive the pathological sample to move. There are several existing slots in the middle of the slightly loosened sampling clamp component. Slowly release the fingers pressing the movable plate 3, and the relatively pulled first traction columns 2 will gradually begin to move closer to each other, and the outwardly extended first traction column 2 will also begin to retract into the inner cavity in the middle of the biopsy forceps 1, and the pathological sample is also moved along with the second traction column 4 and The movable tube 5 is pulled by the first traction column 2 back to a position close to the inner cavity of the biopsy forceps 1. In the process of approaching the inner cavity of the biopsy forceps 1, since the pathological sample is larger than the end of the movable tube 5 close to the second barb 505, it will rub against the outer edge of the groove of the sampling clamp component in the biopsy forceps 1. During the continuous friction process, the bent part of the second barb 505 will be flattened. In the flattened state, the pathological sample can easily fall off from the second barb 505 and fall into the groove on the sampling clamp component of the biopsy forceps 1. The process is repeated until the location of the lesion inside the patient's cervix is sampled and the biopsy forceps 1 can be completely removed from the patient's body, thereby improving the sampling efficiency and improving the uniformity and centralization of pathological sample collection, which is beneficial to the arrangement and classification of pathological samples after the sampling operation is completed.

[0054] The workflow of the technical solution provided by the present invention is as follows:

[0055] In the initial state, the second traction column 4 and the movable tube 5 are positioned slightly below the middle inner cavity of the biopsy forceps 1, that is, without affecting the normal operation of the sampling clamp of the biopsy forceps 1, and the contact position between the movable tube 5 and the sampling clamp component of the biopsy forceps 1 is not in the middle, but slightly below. Figure 9 shown.

[0056] After the biopsy forceps 1 is sent to the pathological position of the patient's cervix and the normal clamping and sampling is completed, the middle finger begins to press the movable plate 3. Under the pressing action, the movable plate 3 will move horizontally from the left end to the right end along the trajectory of the guide column 302. Figure 5As shown; during the displacement process, the ring finger and little finger can press the buckle plate 301 downward, so that when the movable plate 3 moves horizontally to the right end, the open end of the buckle plate 301 will not directly abut the edge of the slotted hole of the biopsy forceps 1, causing the movable plate 3 to be unable to move further. Then, when the movable plate 3 continues to move, the buckle plate 301 is pressed and abutted against the outer wall of the biopsy forceps 1 by the ring finger and little finger, rather than the edge of the open slot of the biopsy forceps 1. Then, the continued displacement of the movable plate 3 will cause the open end of the buckle plate 301 to approach the first clamping groove 303. When the position of the open end of the buckle plate 301 is clamped inside the first clamping groove 303, it indicates that the first clamping groove 303 has completed the limitation of the buckle plate 301, and then the movable plate 3 is limited, so that the first traction column 2 fixed at the upper left end of the movable plate 3 is also pulled to the right, thereby changing the position of the first traction column 2 in the inner cavity of the biopsy forceps 1, which is convenient for preparation for the next process and improves the linkage of the structure and the adaptability of the entire device.

[0057] After the moving plate 3 is pressed to move horizontally, the first traction column 2 fixedly connected to the upper left side thereof will be driven to move horizontally, such as Figure 8 As shown, at this time, the first traction column 2 on the right side will be pulled, and pulling the first traction column 2 will cause the connecting piece 203 fixedly connected to the slot at the end of the first traction column 2 to be pulled. Since the sliding piece 202 is a whole, when the sliding piece 202 is pulled to the right, as shown in FIG. Figure 7 As shown, the first traction column 2 on the left side will move to the left side with the connecting piece 203 and the first traction column 2 on the left side under the action of the sliding piece 202, that is, the first traction column 2 on the left side moves horizontally to the left, and the first traction column 2 on the right side moves horizontally to the right. In this state, the first traction column 2 on the left side extends to the left, that is, extends outward. This is an important step that needs to be completed. Since the sliding piece 202 is tightly attached to the outer surface of the fixed plate 201, and the gap between the fixed plate 201 and the first traction column 2 is slightly larger than the thickness of the sliding piece 202, the sliding piece 202 will not move in the opposite direction after being pulled, and the sliding piece 202 will not be wrinkled or folded, thereby effectively ensuring the movement of the first traction column 2, and at the same time it can also improve the process of the next step, thereby further improving the process of concentrated sampling of the pathological position of the patient's cervix.

[0058] The movable cap 403 is clamped inside the piston groove 402. Before use, the movable cap 403 is clamped and installed inside the piston groove 402 at the end of the first barb 401. After the clamping is stable, the second traction column 4 changes its position as the first traction column 2 moves, and the entire second traction column 4 is fixed in the first traction column 2 on the left, that is, the position extending toward the middle outer cavity of the biopsy forceps 1. The diameter of the bending of the first barb 401 plus the diameter of the second traction column 4 is exactly the same as the diameter of the first traction column 2. In this way, when the second traction column 4 is extended and retracted back and forth from the middle inner cavity of the biopsy forceps 1, the overall friction of the first traction column 2 and the second traction column 4 is reduced, so that when the movable plate 3 is pressed, it will not be time-consuming and laborious due to the excessive friction between the other components, which helps to improve the overall working efficiency and convenience of the biopsy forceps 1.

[0059] After the first traction column 2 is divided into two and displaced in opposite directions, the outwardly extended first traction column 2 will drive the second traction column 4 to move, and the second traction column 4 and the movable tube 5 are clamped by the second adapter groove 501 and the clamping portion 502, and the spring piece 504 is fixedly connected, so the entire movable tube 5 will be driven to move synchronously during displacement. During the movement, the open end of the movable tube 5 close to the second barb 505 will be gradually exposed from the inner cavity of the biopsy forceps 1, and will move along the direction of the clamping component in the biopsy forceps 1. Since the biopsy forceps 1 is in the sampling state at this time, and in order to ensure that the case sample does not fall into the patient's cervix, it is kept in a clamped and fixed state. At this time, pressing the movable plate 3 will drive the first traction column 2, after the two separated first traction columns 2 move in different directions, the second traction column 4 and the movable tube 5 are both driven, and the movable tube 5 and the second barb 505 will approach the pathological sample and finally abut against it, while the first traction column 2 is still moving, so the second traction column 4 and the movable tube 5 are also moving, so the spring piece 504 will be squeezed when abutting against each other, and at this time the first adapting groove 405 and the second clamping groove 406 in the lower part of the movable cap 403 are exactly coincident with the second adapting groove 501 and the clamping portion 502, which can improve the synchronization of the second traction column 4 and the movable tube 5 when they move, and reduce the instability of the second traction column 4 and the movable tube 5 fixedly connected by the spring piece 504.

[0060] After the shrapnel 504 is squeezed, the movable tube 5 will move in the opposite direction, that is, close to the position of the second traction column 4, thereby forming an interactive force with the second traction column 4. At this time, the second barb 505 will be driven by the movable tube 5 to move in the direction close to the second traction column 4, and will also hook the pathological sample. Then, the control valve of the biopsy forceps 1 is slightly loosened, so that the sampling clamp component in the biopsy forceps 1 loses its fixation on the pathological sample, so that the second barb 505 in the movable tube 5 can hook and drive the pathological sample to move. There are several existing slots in the middle of the slightly loosened sampling clamp component. Slowly release the fingers pressing the movable plate 3, and the relatively pulled first traction columns 2 will gradually begin to move closer to each other, and the outwardly extended first traction column 2 will also begin to retract into the inner cavity in the middle of the biopsy forceps 1, and the pathological sample is also moved along with the second traction column 4 and The movable tube 5 is pulled by the first traction column 2 back to a position close to the inner cavity of the biopsy forceps 1. In the process of approaching the inner cavity of the biopsy forceps 1, since the pathological sample is larger than the end of the movable tube 5 close to the second barb 505, it will rub against the outer edge of the groove of the sampling clamp component in the biopsy forceps 1. During the continuous friction process, the bent part of the second barb 505 will be flattened. In the flattened state, the pathological sample can easily fall off from the second barb 505 and fall into the groove on the sampling clamp component of the biopsy forceps 1. The process is repeated until the location of the lesion inside the patient's cervix is sampled and the biopsy forceps 1 can be completely removed from the patient's body, thereby improving the sampling efficiency and improving the uniformity and centralization of pathological sample collection, which is beneficial to the arrangement and classification of pathological samples after the sampling operation is completed.
