Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a cervical biopsy forceps. Background Art

[0002] Cervical biopsy is the biopsy of the living tissue of the cervix, that is, taking a small piece or several pieces of tissue from the cervix for pathological examination to determine the diagnosis. It is mostly used when there is suspicion of cervical cancer, or suspicious cancer cells in the cervical smear, or suspicious specific inflammation, such as cervical tuberculosis, etc. Cervical biopsy can clarify the diagnosis and determine the treatment method. The pathological diagnosis of cervical biopsy is the most reliable basis for diagnosing cervical cancer. Whether it is early or late cervical cancer, it is necessary to perform a pathological diagnosis of cervical biopsy to determine the pathological type and degree of cell differentiation of the tumor.

[0003] The existing cervical biopsy forceps clamp and then break off a piece of tissue on the inner wall of the cervix for detection. In this way, it is easy to fail to clamp when encountering some relatively smooth inner walls of the cervix or some tissues with a relatively large thickness, which will make the operation of medical staff very troublesome. In addition, due to the different constitutions of each patient, there is more secretion in the cervix of some patients. These secretions are likely to affect the medical staff's observation of the inside of the cervix when the medical staff uses the biopsy forceps to operate on the inside of the cervix. Therefore, it is necessary to design a new type of cervical biopsy forceps to solve these problems. Summary of the Invention

[0004] An embodiment of the present invention provides a cervical biopsy forceps to solve the above-mentioned technical problems.

[0005] The embodiments of the present invention adopt the following technical solutions: A cervical biopsy forceps, including a forceps body fixing frame, one end of the forceps body fixing frame is provided with a forceps body clamping member, and the other end of the forceps body fixing frame is provided with a forceps body driving member. The forceps body driving member can be grasped by medical staff and generate power by squeezing with the hand strength of the medical staff. The working end of the forceps body driving member is connected to the forceps body clamping member inside the forceps body fixing frame. The forceps body clamping member performs a clamping action to collect internal cervical tissues by the power generated by the forceps body driving member; a rotating connecting member is further provided on the forceps body fixing frame. The rotating connecting member can rotate the forceps body clamping member installed at one end of the forceps body fixing frame by medical staff on the forceps body fixing frame; a clamping contact member is installed at one end of the forceps body fixing frame where the forceps body clamping member is located. The clamping contact member wraps the forceps body clamping member in a covering form. When the forceps body clamping member collects tissues in the cervix, the clamping contact member contacts the inner wall of the cervix; a trachea fixing frame and a connecting trachea are provided at the lower end of the forceps body fixing frame. The body of the connecting trachea is installed on the forceps body fixing frame through the trachea fixing frame. One end of the connecting trachea is connected to an air pump device, and the other end of the connecting trachea is connected to the clamping contact member. The other end of the connecting trachea can also be suspended under the clamping contact member by the supporting force of the trachea fixing frame. It solves the problem that in the prior art, the cervical biopsy forceps cannot cut off the flesh tissue on the inner wall of the cervix when encountering some relatively smooth inner walls of the cervix or some tissues with a relatively large thickness, resulting in great trouble for medical staff during operation.

[0006] Further, the forceps body fixing frame is composed of a connecting block and a connecting plate. The connecting block is provided at one end on the connecting plate. Two limiting blocks are symmetrically provided on one side of the connecting block. The two limiting blocks are used to cooperate with the forceps body driving member for use. A fixed outer tube is provided at one end of the connecting block. The trachea fixing frame is located at the bottom end of the fixed outer tube. An inner tube is provided inside the fixed outer tube. One end of the inner tube is rotatably connected inside the connecting block, and the other end of the inner tube is rotatably connected to the fixed outer tube. One end of the inner tube located inside the connecting block is connected to the rotating connecting member, and a connecting frame is installed at the other end of the inner tube. The connecting frame is located inside the fixed outer tube, and the connecting frame is connected to the forceps body clamping member. The forceps body fixing frame is mainly used to place and install the forceps body driving member, the forceps body clamping member, the rotating connecting frame, and the clamping contact member.

[0007] Further, two placement chambers are provided in the connecting frame. One of the placement chambers is used to install the forceps body clamping member, and the other placement chamber is provided with a reset connecting plate and a spring. One end of the spring is fixedly connected in the connecting frame, and the other end of the spring is connected to the reset connecting plate. The reset connecting plate is connected to the forceps body driving member. The connecting frame is used to connect the inner tube and install the forceps body clamping member. When the inner tube rotates, it can drive the forceps body clamping member to rotate synchronously, and the connecting frame is also used for the reset function of the forceps body driving member.

[0008] Further, the forceps body clamping member includes a fixed rod and a clamping frame. There are two fixed rods and two clamping frames. The two fixed rods are symmetrically arranged in the connecting frame. A rotating connecting frame is rotatably connected to each fixed rod. The other end of each rotating connecting frame extends outside the connecting frame. The two rotating connecting frames are both connected to the forceps body driving member. Each clamping frame is arranged on a rotating connecting frame. The two clamping frames are symmetrically arranged. The forceps body clamping member is mainly used to cooperate with the forceps body driving member to clamp the tissue in the cervix.

[0009] Further, each clamping frame is a pair of forceps for clamping meat tissue. Its shape is semi-circular, with an arc-shaped front end. There is a chamber for placing meat tissue inside, and the structures on both sides inside are relatively thin. The main function of the two clamping frames is to clamp the tissue on the inner wall of the cervix.

[0010] Further, the forceps body driving member includes a hand fixing frame, a hand pressing frame, a sliding block, a connecting rope, and a pulling rope. The hand fixing frame is arranged below the connecting plate. The hand pressing frame is rotatably installed on one side of the connecting plate, and the hand pressing frame is located beside the hand fixing frame. The sliding block is located on the connecting plate, and the sliding block is slidably installed on one side of the connecting plate through two limiting blocks. One end of the connecting rope is connected to the hand pressing frame, and the other end of the connecting rope is connected to one end of the sliding block. The pulling rope consists of two parts. One part of the pulling rope has two ends respectively connected to the other end of the sliding block and one side of the reset connecting plate, and this part of the pulling rope is located in the inner tube. The second part of the pulling rope is located in the connecting frame. One end of this part of the pulling rope is connected to the other side of the reset connecting plate, and the other end bifurcates to form two ends respectively connected to the two rotating connecting frames, and the second part of the pulling rope is made of a relatively hard material. The forceps body driving member is mainly used to drive the two clamping frames to perform a clamping operation when medical staff need to clamp the tissue in the cervix.

[0011] Further, the rotating connecting member includes a rotating gear and a linkage gear. The rotating gear is rotatably installed on the connecting block through a rod frame. The upper end of the rotating gear protrudes outside the connecting block, and the bottom end of the rotating gear is located above the inner tube. The linkage gear is installed on the inner tube, and the linkage gear meshes with the rotating gear. The rotating connecting member is mainly used to drive the inner tube to rotate.

[0012] Furthermore, the clamping contact member includes a fixed mounting frame and an outer sleeve. The fixed mounting frame is installed on the fixed outer tube. Both ends of the outer sleeve can be installed on the fixed mounting frame, and they are fixedly connected by a fixed pin. One end of the outer sleeve is provided with a front opening, and the other end of the outer sleeve is designed in a closed form. Side openings are provided on both sides of the outer sleeve. A connecting sleeve is sleeved on the outer sleeve, and the connecting sleeve is rotatably connected to the outer sleeve. An opening is provided on one side of the connecting sleeve. When the connecting sleeve rotates on the outer sleeve, the opening will correspond to the two side openings in sequence. The clamping contact member is mainly used to contact the inner wall of the cervix and cooperate with the connecting trachea to suck the tissue to be clamped between the two clamping frames.

[0013] The above at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0014] First, during the extraction process of the present application, after the clamping end of the forceps body and the clamping contact member are located in the cervix, the medical staff operate the biopsy forceps in cooperation with the colposcope to make the clamping contact member contact the inner wall of the cervix. The cervix wall contacted by the clamping contact member in the cervix is judged by the medical staff. After determining the position of the cervix wall and making the clamping contact member contact it, the air pump device connected by the connecting trachea will be started. The air pump device will generate suction in the clamping contact member through the connecting trachea, causing the cervical wall tissue in contact with the clamping contact member to move towards the inside of the clamping contact member. At this time, the cervical wall tissue in the clamping contact member will be located in the clamping member of the forceps body. The medical staff hold the forceps body fixing frame and apply power through the forceps body driving member to make the forceps body clamping member perform a clamping action. In this way, the forceps body clamping member will cut off the cervical wall tissue to complete the cervical tissue collection operation. In this way, the problem that in the prior art, the cervical biopsy forceps cannot cut off the tissue on the inner wall of the cervix when encountering some relatively smooth inner walls of the cervix or some tissues with a relatively large thickness, resulting in great trouble for the medical staff during operation, is solved.

[0015] Second, the connecting trachea can be mounted below the clamping contact end. At this time, when the connecting trachea is located in the cervix, it will directly contact the inner wall of the cervix. At this time, the connecting trachea can be moved to the position where there is more cervical secretion. In this way, when the air pump device works, it can suck the cervical secretion through the connecting trachea. In this way, the problem that when there is more cervical secretion in the prior art, it is easy to affect the medical staff's observation of the inside of the cervix can be solved.

[0016] Third, in the present application, the design of the outer sleeve can enable the outer sleeve to cooperate with the connecting trachea to collect the inner wall tissues of the cervix at multiple positions in the cervix. In this way, the practicability of the biopsy forceps in the present application is greatly increased. Description of the Drawings

Detailed embodiments

[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0030] The technical solutions provided by each embodiment of the present invention will be described in detail below with reference to the drawings.

[0031] An embodiment of the present invention provides a cervical biopsy forceps, which includes a forceps body fixing frame 1. One end of the forceps body fixing frame 1 is provided with a forceps body clamping member 3, and the other end of the forceps body fixing frame 1 is provided with a forceps body driving member 4. The forceps body driving member 4 can be grasped by medical staff and generate power by squeezing with the hand strength of the medical staff. The working end of the forceps body driving member 4 is connected to the forceps body clamping member 3 inside the forceps body fixing frame 1. The forceps body clamping member 3 performs a clamping action to collect internal cervical tissues by the power generated by the forceps body driving member 4. A rotating connecting member 5 is further provided on the forceps body fixing frame 1. The rotating connecting member 5 can rotate the forceps body clamping member 3 installed at one end of the forceps body fixing frame 1 by medical staff on the forceps body fixing frame 1. A clamping contact member 6 is installed at one end of the forceps body fixing frame 1 where the forceps body clamping member 3 is located. The clamping contact member 6 wraps the forceps body clamping member 3 in a covering form. When the forceps body clamping member 3 collects tissues in the cervix, the clamping contact member 6 contacts the inner wall of the cervix. A trachea fixing frame 2 and a connecting trachea 21 are provided at the lower end of the forceps body fixing frame 1. The tube body of the connecting trachea 21 is installed on the forceps body fixing frame 1 through the trachea fixing frame 2. One end of the connecting trachea 21 is connected to an air pump device, and the other end of the connecting trachea 21 is connected to the clamping contact member 6. The other end of the connecting trachea 21 can also be suspended under the clamping contact member 6 by the supporting force of the trachea fixing frame 2.

[0032] In this application, a cervical biopsy forceps for tissue collection inside the cervix for detection is designed. When in use, medical staff hold the forceps body fixing frame 1 and insert the forceps body clamping end into the patient's body, which is convenient for medical staff to observe in cooperation with the existing colposcope. In this way, the biopsy forceps will extract tissue inside the patient's cervix under the observation of medical staff. During the extraction process in this application, first, after the forceps body clamping end and the clamping contact part 6 are inside the cervix, medical staff operate the biopsy forceps in cooperation with the colposcope to make the clamping contact part 6 contact the inner wall of the cervix. The cervical wall contacted by the clamping contact part 6 inside the cervix is judged by the medical staff. After determining the position of the cervical wall and making the clamping contact part 6 contact it, the air pump device connected by the connecting air pipe 21 will start. The air pump device will generate suction force in the clamping contact part 6 through the connecting air pipe 21, causing the cervical wall flesh tissue in contact with the clamping contact part 6 to move towards the inside of the clamping contact part 6. At this time, the cervical wall flesh tissue inside the clamping contact part 6 will be located in the forceps body clamping part 3. Medical staff hold the forceps body fixing frame 1 and apply power through the forceps body driving part 4 to make the forceps body clamping part 3 perform a clamping action. In this way, the forceps body clamping part 3 will cut off the cervical wall flesh tissue to complete the tissue collection operation inside the cervix. By this means, the problem in the prior art that the cervical biopsy forceps cannot cut off the flesh tissue on the inner wall of the cervix when encountering some relatively smooth inner walls of the cervix or some tissues with a relatively large thickness, resulting in great trouble for medical staff during operation, is solved;

[0033] In this application, the connecting air pipe 21 has another function. As mentioned above, on the one hand, the connecting air pipe 21 is used to connect the clamping contact part 6. When connecting the clamping contact part 6, the connecting air pipe 21 can cooperate with the clamping contact part 6 to generate an adsorption force to suck the flesh tissue on the inner wall of the cervix into the clamping contact part 6 for the forceps body clamping part 3 to perform the operation of clamping the flesh tissue. On the other hand, the connecting air pipe 21 can be hung below the clamping contact end. At this time, when the connecting air pipe 21 is inside the cervix, it will directly contact the inner wall of the cervix. At this time, the connecting air pipe 21 can be moved to the position where there is more cervical secretion. In this way, when the air pump device works, it can suck the cervical secretion through the connecting air pipe 21. By this means, the problem in the prior art that when there is more cervical secretion, it is easy to affect the medical staff's observation of the inside of the cervix can be solved.

[0034] Preferably, the pliers body fixing frame 1 is composed of a connecting block 12 and a connecting plate 11. The connecting block 12 is provided at one end on the connecting plate 11. Two limiting blocks 121 are symmetrically provided on one side of the connecting block 12. The two limiting blocks 121 are used in cooperation with the pliers body driving member 4. One end of the connecting block 12 is provided with a fixed outer tube 13. The air tube fixing frame 2 is located at the bottom end of the fixed outer tube 13. An inner tube 14 is provided in the fixed outer tube 13. One end of the inner tube 14 is rotatably connected inside the connecting block 12, and the other end of the inner tube 14 is rotatably connected to the fixed outer tube 13. One end of the inner tube 14 located inside the connecting block 12 is connected to the rotating connecting member 5. A connecting frame 15 is installed at the other end of the inner tube 14. The connecting frame 15 is located inside the fixed outer tube 13. The connecting frame 15 is connected to the pliers body clamping member 3.

[0035] In this application, both the connecting block 12 and the connecting plate 11 are used for connection and placement. The fixed outer tube 13 is used to be placed into the patient's body, and the inner tube 14 can be placed in the fixed outer tube 13. The inner tube 14 is used to connect the pliers body clamping member 3 through the connecting frame 15. And the connection between the inner tube 14 and the rotating connecting member 5 can enable the rotating connecting member 5 to drive the inner tube 14 to rotate in the fixed outer tube 13 during operation, so that the pliers body clamping member 3 will rotate in the clamping contact member 6.

[0036] Preferably, two placement chambers 151 are provided in the connecting frame 15. One of the placement chambers 151 is used to install the pliers body clamping member 3, and the other placement chamber 151 is provided with a reset connecting plate 152 and a spring 153. One end of the spring 153 is fixedly connected in the connecting frame 15, and the other end of the spring 153 is connected to the reset connecting plate 152. The reset connecting plate 152 is connected to the pliers body driving member 4.

[0037] In this application, the connecting frame 15 is mainly rotatably installed inside the fixed outer tube 13, and is used to connect the inner tube 14 and the pliers body clamping member 3. When the inner tube 14 is rotated by the rotating connecting member 5, it cooperates with the inner tube 14 to drive the pliers body clamping member 3 to rotate in the clamping contact member 6. And the reset connecting plate 152 cooperates with the spring 153 to enable the pliers body driving member 4 to reset after driving the pliers body clamping member 3 to clamp, so that the pliers body clamping member 3 can repeat the clamping action.

[0038] Preferably, the pliers body clamping member 3 includes two fixed rods 31 and two clamping frames 33. The two fixed rods 31 are symmetrically arranged inside the connecting frame 15. A rotating connecting frame 32 is rotatably connected to each fixed rod 31. The other end of each rotating connecting frame 32 extends outside the connecting frame 15. The two rotating connecting frames 32 are both connected to the pliers body driving member 4. Each clamping frame 33 is arranged on one rotating connecting frame 32. The two clamping frames 33 are symmetrically arranged.

[0039] In this application, the fixed rod 31 is used to install the rotary connecting frame 32, and the rotary connecting frame 32 is used to install the clamping frame 33. Moreover, the rotary connecting frame 32 is connected to the pliers body driving part 4. In this way, when the pliers body driving part 4 operates, it can drive the two rotary connecting frames 32 to move relatively, so that the two clamping frames 33 can be driven by the two rotary connecting frames 32 to perform the clamping action.

[0040] Preferably, each of the clamping frames 33 is a clamp for clamping and cutting meat tissue. Its shape is semi-circular, the front end is arranged in an arc shape, and there is a chamber for placing meat tissue inside, and the structures on both sides inside are relatively thin.

[0041] In this application, the main function of the two clamping frames 33 is to clamp and cut the cervical inner wall tissue. During operation, the clamping contact part 6 will first cooperate with the connecting air pipe 21 to suck the meat tissue between the two clamping frames 33. Then, the two clamping frames 33 bite through the operation of the pliers body driving part 4. At this time, the two clamping frames 33 will cut the meat tissue through their side walls so that the meat tissue is located in the chamber provided inside the clamping frame 33. Designing the clamping frame 33 in such a shape facilitates the clamping frame 33 to cut the meat tissue.

[0042] Preferably, the pliers body driving part 4 includes a hand fixing frame 41, a hand pressing frame 42, a sliding block 43, a connecting rope 44, and a pulling rope 45. The hand fixing frame 41 is arranged below the connecting plate 11. The hand pressing frame 42 is rotatably installed on one side of the connecting plate 11, and the hand pressing frame 42 is located beside the hand fixing frame 41. The sliding block 43 is located on the connecting plate 11, and the sliding block 43 is slidably installed on one side of the connecting plate 11 through two limiting blocks 121. One end of the connecting rope 44 is connected to the hand pressing frame 42, and the other end of the connecting rope 44 is connected to one end of the sliding block 43. The pulling rope 45 is composed of two parts. One part of the pulling rope 45 has two ends respectively connected to the other end of the sliding block 43 and one side of the reset connecting plate 152, and this part of the pulling rope 45 is located in the inner tube 14. The second part of the pulling rope 45 is located in the connecting frame 15. One end of this part of the pulling rope 45 is connected to the other side of the reset connecting plate 152, and the other end bifurcates to form two ends respectively connected to the two rotary connecting frames 32, and the second part of the pulling rope 45 is made of a relatively hard material.

[0043] In this application, the hand fixing frame 41 is used for medical staff to grasp, and the hand pressing frame 42 is used for medical staff to apply power. When the hand pressing frame 42 is squeezed, it will pull the sliding block 43 to slide backward on the connecting plate 11 through the connecting rope 44. In this way, the sliding block 43 will drive the pulling rope 45 to move in the inner tube 14 at the same time. When the pulling rope 45 moves, on the one hand, it will drive the reset connecting plate 152 to move and compress the spring 153, and on the other hand, it will drive the two rotating connecting frames 32 to rotate on the fixed rod 31 to make the two clamping frames 33 perform a clamping action. After the medical staff releases the pressure applied to the hand pressing frame 42, the return force generated by the spring 153 will reset the reset connecting plate 152. In this way, the reset connecting plate 152 will push the pulling rope 45 of its two parts to reset the two rotating connecting frames 32 and the two clamping frames 33, and the reset connecting plate 152 will also pull the pulling rope 45 of its one part to pull the sliding block 43 to reset. In this way, the hand pressing frame 42 will also be reset for the next operation.

[0044] Preferably, the rotating connector 5 includes a rotating gear 51 and a linkage gear 52. The rotating gear 51 is rotatably mounted on the connecting block 12 through a rod frame. The upper end of the rotating gear 51 protrudes outside the connecting block 12, and the bottom end of the rotating gear 51 is located above the inner tube 14. The linkage gear 52 is mounted on the inner tube 14, and the linkage gear 52 meshes with the rotating gear 51.

[0045] In this application, the rotating gear 51 can be operated by medical staff to rotate. When the rotating gear 51 rotates, it can drive the linkage gear 52 to rotate. In this way, the inner tube 14 can be rotated in the connecting block 12 and the fixed outer tube 13 through the linkage gear 52, so that the inner tube 14 can drive the two clamping frames 33 to rotate in the clamping contact member 6.

[0046] Preferably, the clamping contact member 6 includes a fixed mounting frame 61 and an outer sleeve 62. The fixed mounting frame 61 is mounted on the fixed outer tube 13. Both ends of the outer sleeve 62 can be mounted on the fixed mounting frame 61, and they are fixedly connected by a fixing pin. One end of the outer sleeve 62 is provided with a front opening 622, and the other end of the outer sleeve 62 is designed in a closed form. Both sides of the outer sleeve 62 are provided with side openings 621. A connecting sleeve 63 is sleeved on the outer sleeve 62. The connecting sleeve 63 is rotatably connected to the outer sleeve 62. An opening 631 is provided on one side of the connecting sleeve 63. When the connecting sleeve 63 rotates on the outer sleeve 62, the opening 631 will correspond to the two side openings 621 in turn.

[0047] In this application, the outer sleeve 62 is installed on the fixed outer tube 13 through the fixed mounting bracket 61. The outer sleeve 62 will cover two clamping brackets 33. The outer sleeve 62 can be used in various forms. When in use, the outer sleeve 62 is connected to the connecting air tube 21. When the outer sleeve 62 is located inside the cervix, when the closed-end of the outer sleeve 62 is installed on the fixed mounting bracket 61, the connecting sleeve 63 will rotate on the outer sleeve 62 to close the side openings 621 provided on both sides of the outer sleeve 62. At this time, only the front opening 622 of the outer sleeve 62 is in an open state. Medical staff will make the front opening 622 end of the outer sleeve 62 contact and fit with the meat tissue on the inner wall of the cervix that needs to be collected. At this time, the inner chamber of the outer sleeve 62 will be closed. When the connecting air tube 21 operates through the air pump device, the connecting air tube 21 will extract air from the outer sleeve 62 until a part of the meat tissue on the inner wall of the cervix bulges out and is located in the outer sleeve 62. At this time, the two clamping brackets 33 can cut off the bulging meat tissue;

[0048] The outer sleeve 62 can also choose to connect the end with the front opening 622 to the fixed mounting bracket 61. At this time, the other end of the outer sleeve 62 will be closed. Then rotate the connecting sleeve 63 to make the opening 631 correspond to one of the side openings 621 on the outer sleeve 62, so that one side opening 621 can communicate with the outside. Such an operation can make the side opening 621 of the outer sleeve 62 correspond to the inner side end of the cervix. Using the same method as above, the meat tissue at the inner side end of the cervix can bulge into the outer sleeve 62. At this time, the medical staff can drive the linkage gear 52 by rotating the gear 51 to rotate the inner tube 14 to make the two clamping brackets 33 rotate, so that the two clamping brackets 33 correspond to the opened side opening 621. In this way, the bulging meat tissue can be located between the two clamping brackets 33, and then the two clamping brackets 33 can cut it off. In this way, the sample collection of the inner side end of the cervix can be realized.

[0049] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
