Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not limit the right thereto.
Embodiment 1, refer to fig. 1-6, a cervical tumor tissue sampling and separating forceps for gynecology comprises a main forceps body 2 and an auxiliary forceps body 3, the tails of which are fixedly provided with a grab handle 1, and the middle parts of the main forceps body 2 and the auxiliary forceps body 3 are rotatably connected;
a round hole 4 is formed in the middle of the main clamp body 2, a rectangular groove 5 is formed in the bottom end of the round hole 4, a tissue accommodating groove 6 is formed in the top of the main clamp body 2, an elastic clamping strip is fixedly mounted at the bottom of the tissue accommodating groove 6, and a main cutting tooth 7 is fixedly mounted on the top of the main clamp body 2 and one side of the tissue accommodating groove 6;
a convex block 8 matched with the round hole 4 and the rectangular groove 5 for use is fixedly arranged in the middle of the auxiliary clamp body 3, a stop block 9 is fixedly arranged on one end face of the convex block 8, an elastic clamping strip contact groove 10 is formed in the top of the auxiliary clamp body 3, and an auxiliary cutting tooth 11 matched with the main cutting tooth 7 for use is fixedly arranged on the top of the auxiliary clamp body 3 and one side of the elastic clamping strip contact groove 10; the middle part of the auxiliary clamp body 3 is also provided with a contraction gap 12. The cross section of the grab handle 1 is in an oval shape; the cross section of the stop block 9 is arranged in a circular shape, and after the main clamp body 2 and the auxiliary clamp body 3 are installed, the main clamp body 2 is positioned between the auxiliary clamp body 3 and the stop block 9 on the auxiliary clamp body 3.
In embodiment 1, the setting of the contraction gap 12 is used for the main cutting tooth 7 and the auxiliary cutting tooth 11 in the contact state when the projection 8 moves along the rectangular groove 5, and the auxiliary cutting tooth 11 can continuously contact and interfere with the main cutting tooth 7, so that the pathological tissue between the auxiliary cutting tooth 11 and the main cutting tooth 7 is cut by the main cutting tooth 7 and the auxiliary cutting tooth 11 again.
In the cervical tumor tissue sampling and separating forceps for gynecology based on the embodiment 2 and the embodiment 1, the cross sections of the main forceps body 2 and the auxiliary forceps body 3 are both square.
Embodiment 4, the cervical tumor tissue sampling and separating forceps for gynecology based on embodiment 1, the elastic clamping strip is composed of a horizontal part 13 and an inclined part 14, the cross section of the horizontal part is rectangular, one end of the horizontal part is fixedly connected with one end of the inclined part 14, the middle part of the inclined part 14 is positioned in the tissue accommodating groove 6 and below the top end of the main cutting tooth 7;
the elastic clamping strip is made of elastic polyethylene clamping strip.
Example 5, the cervical tumor tissue sampling and separating forceps for gynecology use described in example 1 were set such that the length of the contraction gap 12 was set to 15% of the total length of the forceps body 3, and the width of the contraction gap 12 was set to 14% of the width of the forceps body 3.
When pathological tissues are cut, the main clamp body 2 and the auxiliary clamp body 3 are contracted, so that the pathological tissue part is cut through the contraction of the main cutting teeth 7 and the auxiliary cutting teeth 11, most of the pathological tissues can only be cut off, at the moment, a small part of the pathological tissues which are difficult to cut are not cut off, at the moment, the included angle between the main clamp body 2 and the auxiliary clamp body 3 is 0 degree, at the moment, the lug 8 on the auxiliary clamp body 3 moves along the rectangular groove 5 in the round hole 4 on the main clamp body 2, namely, the auxiliary clamp body 3 moves linearly along the main clamp body 2, during the process, as the middle part of the auxiliary clamp body 3 is provided with the contraction gap 12, the arrangement of the contraction gap 12 enables the main cutting teeth 7 and the auxiliary cutting teeth 11 which are in a contact state to move relatively, namely, when the lug 8 on the auxiliary clamp body 3 moves along the rectangular groove 5, sawteeth on the auxiliary clamp body 3 and the main clamp body 2 are blocked continuously, i.e., the secondary cutting tooth 11 can be constantly in contact with the primary cutting tooth 7 to re-cut the incompletely separated pathological tissue, during which the elastic trip contact groove 10 on the top of the secondary caliper body 3 can be in blocking interference with the elastic trip on the primary caliper body 2, thereby causing the elastic clamping strip to deform, leading the inclined part 14 of the elastic clamping strip to be continuously contacted with the saw teeth of the auxiliary cutting teeth 11 on the auxiliary cutting teeth 11, scraping the pathological tissues on the saw teeth of the auxiliary cutting teeth 11 to a certain extent, when the convex block 8 on the auxiliary forceps body 3 is no longer positioned in the rectangular groove 5, the elastic clamping strip is restored to the initial state, the pathological tissues are positioned in the inner wall of the elastic clamping strip or the tissue accommodating groove 6, can carry out next tissue cutting, change in the past at every turn the drawback that can only cut once of cutting, realize once stretching into the effect of many times cutting, its structural design is reasonable, and the cutting effect is good.
