Abstract
The utility model discloses a cervix biopsy tong which solves the technical problem of small checking angles. The utility model has the main proposals that the cervix biopsy tong comprises a tong rod. The head part of the tong rod is provided with a tong clamp; the tail part of the tong rod is provided with a handle; the tong clamp comprises an upper tong clamp and a lower tong clamp; the tong rod comprises an upper tong rod and a lower tong rod which are respectively bent into a double-layer stair shape; a space limiting device which can be used for limiting the relative movements of the upper tong rod and the lower tong rod is arranged between the upper tong rod and the lower tong rod; the handle comprises a front handle and a back handle; the lower tong clamp and lower tong rod are in fixed connection; the upper tong clamp is rotatablely and respectively connected with the front ends of the upper tong rod and the lower tong rod; the front handle is rotatablely connected with the upper tong rod and the lower tong rod; the back handle and the tail part of the lower tong rod are formed into an integrative body; springs are arranged between the front handle and the back handle. The utility model has the advantages of simple structure, convenient operation and large checking angles. The utility model is a replacing product for an I-shaped cervix biopsy tong and is suitable for gynecological checking.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of gynecological and clamps with cervical biopsy.
Background technology
At present, when gynecologial examination, usually adopt the endoscope-use biopsy forceps, claw beam is a yi word pattern, checks that angle is little, has limited examination scope.Also have a kind of biopsy forceps, it has handle, and handle side is to having chute, handle one termination has flexible pipe, and the flexible pipe other end joins through biopsy joint and biopsy forceps, is provided with entry needle in the middle of biopsy forceps, and pass biopsy joint and flexible pipe and pushing needle bar and join, injection interface and pushing needle bar communicate, and the handle other end is provided with handgrip, and steel wire and biopsy joint join on the handgrip, this structure, the cost height, operation easier is big, is not suitable for gynecologial examination and uses.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of cervical biopsy pincers are provided, check the little technical problem of angle to solve it.
For solving the problems of the technologies described above, the technical solution of the utility model is: the cervical biopsy pincers, comprise claw beam, the head of claw beam is provided with clamp, the afterbody of claw beam is provided with handle, and described clamp comprises clamp and following clamp, and described claw beam comprises claw beam and following claw beam and is bent into the quadruple board platform scalariform respectively, be provided with the stopping means that can limit its relative motion between last claw beam and the following claw beam, described handle comprises front hand grip and back handle; Following clamp is fixedlyed connected with following claw beam, last clamp is rotatably connected with the front end of last claw beam and following claw beam respectively, front hand grip is rotatably connected with last claw beam and following claw beam respectively, and back handle is made as one with the afterbody of following device bar, is provided with spring between front hand grip and the back handle.
After having adopted technique scheme, because following clamp is fixedlyed connected with following claw beam, last clamp is rotatably connected with the front end of last claw beam and following claw beam respectively, front hand grip is rotatably connected with last claw beam and following claw beam respectively, back handle is made as one with the afterbody of following device bar, push forward and backward handle, upper and lower claw beam just can drive upper and lower clamp closure, and the spring that is arranged between the forward and backward handle can make it reset.Because upper and lower claw beam also is bent into the quadruple board platform scalariform respectively, check angle so increased it.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the structure cutaway view of this utility model embodiment.
The specific embodiment
As shown in drawings, the cervical biopsy pincers, comprise claw beam 2, the head of claw beam 2 is provided with clamp 1, and the afterbody of claw beam 2 is provided with handle 3, and described clamp 1 comprises clamp 11 and following clamp 12, described claw beam 2 comprises claw beam 21 and following claw beam 22 and is bent into the quadruple board platform scalariform respectively, the afterbody of following claw beam 22 is provided with groove 221, and last claw beam 21 is provided with the projection 211 that matches with it, and projection 211, groove 221 are in order to limit the relative motion of upper and lower claw beam 21,22.Handle 3 comprises front hand grip 31 and back handle 32; Following clamp 12 is fixedlyed connected with following claw beam 22, last clamp 11 is rotatably connected with the front end of last claw beam 21 and following claw beam 22 respectively, front hand grip 31 is rotatably connected with last claw beam 21 and following claw beam 22 respectively, back handle 32 is made as one with the afterbody of following device bar 22, be provided with spring 4 between front hand grip 31 and the back handle 32, spring 4 is preferentially selected leaf spring for use.
Push forward and backward handle 31,32, upper and lower claw beam 21,22 just can drive upper and lower clamp 11,12 closures, and the spring 4 that is arranged between the forward and backward handle 31,32 can make it reset.Because upper and lower claw beam 21,22 is bent into the quadruple board platform scalariform respectively, check angle so increased it.
This utility model is simple in structure, and is easy to use, checks that angle is big, is the substitute products of " one " font cervical biopsy pincers, and suitable gynecologial examination is used.
