Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a biopsy forceps. Background Art
[0002] Biopsy forceps are an indispensable tool for endoscopic examination and pathological specimen collection. In direct laparoscopic intra-abdominal surgery, biopsy forceps are needed to bite and cut the lesion site in the abdominal cavity for sampling and analysis, which is beneficial to the diagnosis of the disease and the normal progress of the operation.
[0003] The existing biopsy forceps head assembly has a small storage space and can only be used for a single small amount of sampling, so sampling becomes very cumbersome. At the same time, since the direction of the forceps head is fixed and cannot be adjusted, it requires multiple attempts to clamp the diseased tissue, resulting in the biopsy forceps lacking convenience when working. For this reason, we propose a biopsy forceps. Utility Model Content

[0006] Preferably, two side walls of the handle body are penetrated by symmetrically arranged sliding grooves, and two ends of the lifting rod are slidably connected to the sliding grooves.
[0007] Preferably, a guide groove is provided at the bottom of the adjusting rod, and the sliding block is clamped in the guide groove.
[0008] Preferably, an auxiliary wire is provided between the first auxiliary wire groove and the second auxiliary wire groove.
[0009] Preferably, the universal ball is slidably connected to the adjusting rod.
[0010] The beneficial effects of the utility model are as follows: first, the lifting rod is pulled to drive the main line through the compression spring, and then the main line, the adjusting rod, the adjusting box, and the clamp head mechanism are used in conjunction with each other, so that the diseased tissue clamped by the clamp head mechanism can be placed in the adjusting cavity, and then the next clamping is performed, thereby improving the clamping efficiency. At the same time, the rotating drive rod drives the rotating rod through the auxiliary line, and then the clamping angle of the clamp head mechanism can be adjusted through the setting of the slider, the guide groove, and the adjusting rod, so as to facilitate the clamping of diseased tissues in different angle areas.

DETAILED DESCRIPTION
[0017] Reference Figure 1-5The biopsy forceps include a handle body 1, a guide core 2 is provided at the bottom of the handle body 1, an adjusting box 3 is fixedly connected to the top of one end of the guide core 2, an annular handle 11 is fixedly connected to the top of the handle body 1, a spring 12 is fixedly connected to the top of the inner wall of the handle body 1, a lifting rod 13 is fixedly connected to the bottom of the spring 12, a main line 14 is fixedly connected to the bottom of the lifting rod 13, and the main line 14 is movable through the guide core 2 and extends to the inside of the adjusting box 3, a universal ball 104 is fixedly connected to the top of one end of the main line 14, an adjusting rod 4 is provided at one end of the universal ball 104, a clamp head mechanism 5 is installed on the top of the adjusting rod 4, an adjusting cavity 31 is opened on the outer surface of one side of the adjusting box 3, a rotating rod 6 is rotatably connected to the bottom end of the inner wall of the adjusting cavity 31, a slider 61 is fixedly connected to the top of the rotating rod 6, a first auxiliary line groove 62 is opened on the outer surface of one end of the rotating rod 6, a driving rod 8 is rotatably connected to the lower end of one side of the handle body 1, and a second auxiliary line groove 81 is opened on the outer surface of one end of the driving rod 8.
[0018] Furthermore, symmetrically arranged sliding grooves 101 are formed through the two side walls of the handle body 1 , and both ends of the lifting rod 13 are slidably connected to the sliding grooves 101 , so that the lifting rod 13 can move upward along the sliding grooves 101 .
[0019] Furthermore, a guide groove 41 is provided at the bottom of the adjusting rod 4, and a slider 61 is stuck in the guide groove 41. The slider 61 will slide back and forth along the guide groove 41, and the slider 61 and the guide groove 41 are both rectangular, so as to drive the adjusting rod 4 to rotate.
[0020] Furthermore, an auxiliary wire 7 is provided between the first auxiliary wire groove 62 and the second auxiliary wire groove 81 , and the driving rod 8 can drive the rotating rod 6 to rotate through the auxiliary wire 7 .
