Abstract

The invention relates to a clamp fastener used as a skeletal fixation plate, characterized in that the clamp end of a handle is provided with a clamp block and a pressure lever; two perforated grooves are arranged in the clamp block; a tenaculum and the pressure lever are respectively arranged in the two grooves and are moveably connected with the clamp block; the grip end of the handle is provided with an upper grip arm and a lower grip arm between which a rack is arranged. When in use, a lock plate is inserted into a limited incision and the tenaculum is also inserted into the incision to hook the inside skeleton, and then the tenaculum is locked on the clamp fastener, the pressure lever is made to prop up the lock plate, and the grip end of the handle keeps being pressed to fix the lock plate and the skeleton; the rack arranged at the grip end of the handle can tightly lock to keep the fixation state, ensuring the tight joint of the lock plate and the skeleton, thereby the fracture fixation effect can be improved, the fixation technique can be simplified and the fracture reduction operation can meet the mini-incision needs.

Description

A kind of clamper that is used for the skeletal fixation plate

Technical field:

The present invention relates to technical field of medical, specifically a kind ofly be used for that appendicular skeleton fracture, bone does not connect etc. reset and the clamper of internal fixation.

Background technology:

At present appendicular skeleton and lockplate and other fixing heads fixedly the time, lack one and can satisfy Wicresoft's requirement, clinical, often, brought certain degree of difficulty to operation owing to skeleton does not have finely to reset and fix Mu.

Summary of the invention:

The object of the present invention is to provide a kind of improved clamper that is used for the skeletal fixation plate, it can overcome gripper clamp in the prior art can't satisfy the some shortcomings that the fixed effect difference is torn in Wicresoft's requirement, bone open.

To achieve these goals, technical scheme of the present invention is: a kind of clamper that is used for the skeletal fixation plate, it comprises that mainly handle and grasps hook, wherein handle comprises a bare terminal end and a grip end, it is characterized in that: the bare terminal end of handle is provided with grip block and depression bar, be provided with two cell bodies that run through in the grip block, grasp hook and depression bar and be separately positioned in two cell bodies, and form movable the connection with grip block; The grip end of handle is provided with upper and lower two grip arm, is provided with a tooth bar between two grip arm.

During use, elder generation inserts lockplate at the limited incision place, then grasp hook and insert incision and hook inboard skeleton, will grasp to be hooked on the clamper then to lock, and depression bar and lockplate offseted, continue the grip end of pressurized handgrip, make lockplate and skeletal fixation, because the grip end of handle is provided with tooth bar, can firmly lock stationary state, guarantee fitting tightly between lockplate and the skeleton, can improve bone and tear fixed effect open, be simplified to fix technology, make bone tear reset operation open and satisfy Wicresoft's needs.

Description of drawings:

Fig. 1 is the structural representation of one embodiment of the invention

Fig. 1 is the structural representation of further embodiment of this invention

The specific embodiment:

The invention will be further described below in conjunction with drawings and Examples.

The present invention comprises that mainly handle 1 and grasps hook 2, wherein handle comprises a bare terminal end and a grip end, its difference with the prior art is: the bare terminal end of handle is provided with grip block 3 and depression bar 4, be provided with two cell bodies that run through in the grip block, grasp hook 2 and depression bar 4 and be separately positioned in two cell bodies, and form movable the connection with grip block, wherein grasping hook can separate with handle, so that insert separately in the otch on limbs surface, guaranteed the motility that the present invention uses.The grip end of handle is provided with, following two

grip arm

5,6, be provided with a tooth bar 7 between two grip arm, last grip arm 5 is provided with a shell fragment 8, one end of shell fragment is fixedlyed connected by a screw with last grip arm, the other end of shell fragment is a free end, the free end and the tooth bar of shell fragment offset, form between one end of tooth bar and the last grip arm and be rotatably connected, the bottom of following grip arm 6 is provided with the double wedge 9 that matches with the profile of tooth of tooth bar, the other end of double wedge and tooth bar is inconsistent, after in double wedge is fastened on tooth bar, under the effect of shell fragment whole holder handle just with the state that goes out a kind of locking, can unclamp tooth bar after pulling shell fragment.

One end of depression bar is fixedlyed connected with the bare terminal end of handle, and the other end of depression bar is provided with sawtooth, and a saw blade on the depression bar and a lockplate 10 offset.Grasp hook and be formed by connecting by support bar 11 and the crotch 12 that links to each other with support bar, the lateral surface of support bar and the medial surface of crotch are provided with sawtooth, and wherein the arc diameter of crotch is 30-45mm.

Be embedded with a quick double thread screw 13 and a steel ball 14 on the grip block, a side of steel ball and a spring 15 offset, and the opposite side of steel ball offsets with the lateral surface sawtooth that grasps hook, and the double thread screw also offsets with the lateral surface sawtooth that grasps hook fast.

In force, elder generation inserts lockplate at the limited incision place, then grasp hook and insert incision and hook inboard skeleton, will grasp to be hooked on the clamper then to lock, and depression bar and lockplate offseted, continue the grip end of pressurized handgrip, make lockplate and skeletal fixation, because the grip end of handle is provided with tooth bar, can firmly lock stationary state, guarantee fitting tightly between lockplate and the skeleton, can improve bone and tear fixed effect open, be simplified to fix technology, make bone tear reset operation open and satisfy Wicresoft's needs.The stiff end (being quick double thread screw and steel ball) of whole grip block can be arranged on the opposite side (specifically referring to Fig. 2) of depression bar simultaneously, wholely like this grasp the opposite side that hook also just is arranged on depression bar, to cooperate the compound needs of different skeletal fixations, can also on handle, dispose simultaneously the hook that grasps of various different sizes, to satisfy the needs of different operations.
