Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a gastrointestinal endoscope cell clamp. Background Technology

[0002] Cytometer forceps are endoscopic accessories used to directly manipulate mucosal tissues. They are indispensable tools when endoscopic examinations require obtaining pathological biopsies.

[0003] In the existing technology, after the cell forceps are closed to grasp human tissue in the stomach and intestines, the human tissue will stick to the cell forceps due to its own stickiness when the cell forceps are released, and cannot be removed. Therefore, it is necessary to remove the human tissue from the cell forceps with filter paper and place it in a collection dish, which is a bit cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a gastrointestinal endoscopic cytometer, which aims to solve the technical problem that in existing technologies, after the cytometer is closed to grasp human tissue in the stomach and intestines, the human tissue will stick to the cytometer due to its own adhesiveness when the cytometer is released, making it impossible to remove. Therefore, it is necessary to remove the human tissue from the cytometer through filter paper and place it in a collection dish, which is a somewhat cumbersome step.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A gastrointestinal endoscopic cytometer includes a gripping mechanism and an ejection mechanism disposed on the gripping mechanism. The gripping mechanism includes two jaws that move relative to each other, with a through hole extending through the jaws. The ejection mechanism includes a relative rotating assembly disposed on the gripping mechanism and two arc-shaped push rods disposed opposite to each other on the relative rotating assembly. The size of the arc-shaped push rods is smaller than the size of the through hole. The relative rotating assembly drives the two arc-shaped push rods to move relative to each other, so that the arc-shaped push rods pass through the through hole and eject human tissue from the jaws.

[0007] According to one aspect of the above technical solution, the clamping mechanism includes a flexible sleeve, a fixing block and a driving component respectively disposed at both ends of the flexible sleeve, a clamping component disposed on the fixing block, and a pull rope located in the flexible sleeve, wherein the two ends of the pull rope are respectively connected to the clamping component and the driving component.

[0008] According to one aspect of the above technical solution, the drive component includes a mounting block, a first sliding block slidably disposed on the mounting block, and a first elastic member connecting the mounting block and the first sliding block, wherein one end of the pull rope is fixedly connected to the first sliding block.

[0009] According to one aspect of the above technical solution, the fixing block is provided with an installation groove, and the clamping assembly includes a first rotating shaft slidably disposed in the installation groove, a first connecting rod and a second connecting rod disposed opposite to the first rotating shaft, a second rotating shaft rotatably connected to the first connecting rod, a third rotating shaft rotatably connected to the second connecting rod, a fourth rotating shaft rotatably disposed in the installation groove, and a third connecting rod and a fourth connecting rod disposed opposite to the fourth rotating shaft. One end of the third connecting rod is rotatably connected to the second rotating shaft, and one end of the fourth connecting rod is rotatably connected to the third rotating shaft. The two jaws are respectively fixedly connected to the other ends of the third connecting rod and the fourth connecting rod, and the other end of the pull rope is fixedly connected to the first rotating shaft.

[0010] According to one aspect of the above technical solution, the mounting groove is provided with a first sliding groove for the first rotating shaft to slide.

[0011] According to one aspect of the above technical solution, a second elastic element is provided at one end of the pull rope near the first rotating shaft, and the two ends of the second elastic element are respectively connected to the fixing block and the first rotating shaft.

[0012] According to one aspect of the above technical solution, the flexible sleeve is provided with a second sliding groove, and the pull rope is provided with a second sliding block that cooperates with the second sliding groove.

[0013] According to one aspect of the above technical solution, the relative rotation assembly includes a fifth rotating shaft disposed on the fixed block, a first slotted rod and a second slotted rod disposed opposite to each other on the fifth rotating shaft, a first connecting rod disposed at the free end of the first slotted rod, and a second connecting rod disposed at the free end of the second slotted rod. The two arc-shaped top rods are respectively fixedly connected to the first connecting rod and the second connecting rod. A first sliding hole is provided through the first slotted rod, and a second sliding hole is provided through the second slotted rod. The relative rotation assembly also includes a sixth rotating shaft and a seventh rotating shaft rotatably disposed on the fixed block. The sixth rotating shaft is located in the first sliding hole, and the seventh rotating shaft is located in the second sliding hole.

[0014] According to one aspect of the above technical solution, the fixed block is provided with a third sliding groove for the fifth rotating shaft to slide, and a third elastic element is provided between the fifth rotating shaft and the third sliding groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By setting an ejection mechanism on the gripping mechanism, when human tissue is gripped and removed by the gripping mechanism and the human tissue is stuck to the jaws, the relative rotation component controls the relative movement of two arc-shaped ejector rods located near the through hole. The arc-shaped ejector rods pass through the through hole and push the human tissue stuck to the jaws outward. Since the arc-shaped ejector rods are small in size, the human tissue will not stick to the arc-shaped ejector rods. Moreover, they can quickly reciprocate through the relative rotation component, so the human tissue can be separated from the jaws very cleanly, which is very convenient to use.

[0017] This invention can conveniently separate human tissue from the forceps, eliminating the need for the tedious process of peeling off human tissue using filter paper. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 8 The image shows a gastrointestinal endoscopic cell forceps according to an embodiment of the present invention, including a gripping mechanism 10 and an ejection mechanism 40 disposed on the gripping mechanism 10. The gripping mechanism 10 includes two jaws 51 that move relative to each other, and a through hole 52 is provided through the jaws 51. The ejection mechanism 40 includes a relative rotation component disposed on the gripping mechanism 10 and two arc-shaped push rods 61 disposed opposite to each other on the relative rotation component. The size of the arc-shaped push rods 61 is smaller than the size of the through hole 52. The relative rotation component drives the two arc-shaped push rods 61 to move relative to each other, so that the arc-shaped push rods 61 pass through the through hole 52 and eject the human tissue on the jaws 51.

[0034] Understandably, this utility model provides an ejection mechanism 40 on the clamping mechanism 10. When human tissue is clamped and removed by the clamping mechanism 10 and the human tissue is stuck to the jaws 51, the relative rotation component controls the relative movement of two arc-shaped push rods 61 located near the through hole 52. The arc-shaped push rods 61 pass through the through hole 52 and push the human tissue stuck to the jaws 51 outward. Since the arc-shaped push rods 61 are small in size, the human tissue will not stick to the arc-shaped push rods 61. Moreover, the relative rotation component can quickly reciprocate, so the human tissue can be very cleanly separated from the jaws 51, making it very convenient to use.

[0035] This invention can conveniently separate human tissue from the jaws 51 without the need for the tedious process of peeling off human tissue using filter paper.

[0036] Specifically, in this embodiment, the clamping mechanism 10 includes a flexible sleeve 30, a fixing block 11 and a driving assembly 20 respectively disposed at both ends of the flexible sleeve 30, a clamping assembly disposed on the fixing block 11, and a pull rope 31 located in the flexible sleeve 30. The two ends of the pull rope 31 are respectively connected to the clamping assembly and the driving assembly 20. The driving assembly 20 includes a mounting block 21, a first sliding block 22 slidably disposed on the mounting block 21, and a first elastic member 23 connecting the mounting block 21 and the first sliding block 22. One end of the pull rope 31 is fixedly connected to the first sliding block 22. The fixing block 11 has a mounting groove 12, and the clamping assembly includes a component slidably disposed in the mounting groove. The mounting groove 12 includes a first rotating shaft 13, a first connecting rod 14 and a second connecting rod 15 mounted on the first rotating shaft 13, a second rotating shaft 16 rotatably connected to the first connecting rod 14, a third rotating shaft 17 rotatably connected to the second connecting rod 15, a fourth rotating shaft 50 rotatably mounted in the mounting groove 12, and a third connecting rod 18 and a fourth connecting rod 19 mounted on the fourth rotating shaft 50. One end of the third connecting rod 18 is rotatably connected to the second rotating shaft 16, and one end of the fourth connecting rod 19 is rotatably connected to the third rotating shaft 17. The two jaws 51 are fixedly connected to the other ends of the third connecting rod 18 and the fourth connecting rod 19, respectively. The other end of the pull rope 31 is fixedly connected to the first rotating shaft 13.

[0037] Understandably, when it is necessary to clamp human tissue through the clamping mechanism 10, the clamping component is sent into the gastrointestinal tract through the flexible sleeve 30. Then, the first sliding block 22 is pulled, causing the first sliding block 22 to drive the pull rope 31 to move outward a short distance. The first elastic element 23 is pulled up, and the end of the pull rope 31 near the clamping component also moves outward a short distance. This causes the pull rope 31 to drive the first rotating shaft 13 to move towards the flexible sleeve 30. Through the linkage of the first connecting rod 14, the second connecting rod 15, the second rotating shaft 16, the third rotating shaft 17, the fourth rotating shaft 50, the third connecting rod 18, and the fourth connecting rod 19, the jaws 51 on the third connecting rod 18 and the fourth connecting rod 19 move relative to each other to form a clamping action to clamp human tissue. After clamping, the clamping component is removed from the gastrointestinal tract while the two jaws 51 are holding the tissue. The first sliding block 22 is released, and due to the reset effect of the first elastic element 23, the pull rope 31 drives the first rotating shaft 13 back to its original position.

[0038] Preferably, the mounting groove 12 is provided with a first sliding groove 54 for the first rotating shaft 13 to slide; the end of the pull rope 31 near the first rotating shaft 13 is provided with a second elastic element 53, and the two ends of the second elastic element 53 are respectively connected to the fixing block 11 and the first rotating shaft 13.

[0039] Understandably, the purpose of setting the first sliding groove 54 is to make the first rotating shaft 13 move more smoothly and ensure the stable operation of the clamping component. The function of the second elastic element 53 is that when the first sliding block 22 is released, the restoring force of the second elastic element 53 allows the first rotating shaft 13 to return to its original position more smoothly, preventing the pull rope 31 from being too soft and unable to push the first rotating shaft 13 back to its original position.

[0040] Preferably, the flexible sleeve 30 is provided with a second sliding groove 33, and the pull rope 31 is provided with a second sliding block 32 that cooperates with the second sliding groove 33.

[0041] Understandably, the purpose of the second sliding block 32 and the second sliding groove 33 is to allow a long section of the pull rope 31 to slide smoothly within the flexible sleeve 30, preventing the pull rope 31 from sliding unevenly due to its soft texture. The second sliding block 32 should be spaced out on the pull rope 31.

[0042] Furthermore, the relative rotation assembly includes a fifth rotating shaft 43 disposed on the fixed block 11, a first slotted rod 44 and a second slotted rod 45 disposed opposite to each other on the fifth rotating shaft 43, a first connecting rod 60 disposed at the free end of the first slotted rod 44, and a second connecting rod 62 disposed at the free end of the second slotted rod 45. The two arc-shaped top rods 61 are fixedly connected to the first connecting rod 60 and the second connecting rod 62 respectively. A first sliding hole 48 is provided through the first slotted rod 44, and a first sliding hole 48 is provided through the second slotted rod 45. The relative rotation assembly includes a second sliding hole 49 and a sixth rotating shaft 46 and a seventh rotating shaft 47 rotatably disposed on the fixed block 11. The sixth rotating shaft 46 is located in the first sliding hole 48, and the seventh rotating shaft 47 is located in the second sliding hole 49. The fixed block 11 is provided with a third sliding groove 41 for the fifth rotating shaft 43 to slide. A third elastic member 42 is provided between the fifth rotating shaft 43 and the third sliding groove 41. The first slot rod 44 and the second slot rod 45 are rotatably connected to the fifth rotating shaft 43.

[0043] Understandably, when human tissue is stuck to the jaws 51 and cannot be removed, the fifth rotating shaft 43 can be slid along the third sliding groove 41 toward one end of the flexible sleeve 30, the third elastic element 42 can be pulled up, and the fifth rotating shaft 43 can be moved, so that the first slot rod 44 and the second slot rod 45 are relatively close, and the first connecting rod 60 and the second connecting rod 62 drive the two arc-shaped push rods 61 to be relatively close. The arc-shaped push rods 61 pass through the through hole 52 and push the human tissue off the jaws 51. Preferably, the end of the arc-shaped push rod 61 is rounded, which is to better reduce the surface area and prevent the human tissue from sticking to the arc-shaped push rod 61. After the human tissue is pushed out, the fifth rotating shaft 43 is released, and the restoring force of the third elastic element 42 will drive the fifth rotating shaft 43 to return to its original position, so that the arc-shaped push rod 61 moves away from the through hole 52.

[0044] In summary, the gastrointestinal endoscopic cell forceps in the above embodiments of this utility model, by setting an ejection mechanism on the gripping mechanism, when human tissue is gripped and removed by the gripping mechanism and the human tissue adheres to the forceps jaws, the relative rotation component controls the relative movement of two arc-shaped push rods located near the through hole. The arc-shaped push rods pass through the through hole and push the human tissue adhering to the forceps jaws outward. Since the arc-shaped push rods are small in size, the human tissue will not stick to the arc-shaped push rods, and can be quickly reciprocated by the relative rotation component. Therefore, the human tissue can be very cleanly separated from the forceps jaws, making it very convenient to use.

[0045] This invention can conveniently separate human tissue from the forceps, eliminating the need for the tedious process of peeling off human tissue using filter paper.
