Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0009] The present invention mainly includes a handle 1 and a gripping hook 2, wherein the handle includes a gripping end and a gripping end, the difference from the prior art is that the gripping end of the handle is provided with a gripping block 3 and a pressing bar 4, There are two through grooves in the clamping block, the grasping hook 2 and the pressure rod 4 are respectively arranged in the two grooves, and form a movable connection with the clamping block, wherein the grasping hook can be separated from the handle, so as to separate Insertion into the incision on the surface of the limb guarantees the flexibility of use of the present invention. The grip end of the handle is provided with two upper and lower grip arms 5, 6, a rack 7 is arranged between the two grip arms, and a shrapnel 8 is arranged on the upper grip arm 5, and one end of the s...

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

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a clamper for the reduction and internal fixation of extremity bone fractures and nonunions. Background technique: [0002] At present, there is a lack of one that can meet the minimally invasive requirements for the fixation of extremity bones, locking plates and other fixation plates. In clinical practice, the bones are often not well reset and fixed, which brings certain difficulties to the operation. Invention content: [0003] The object of the present invention is to provide an improved holder for bone fixation plate, which can overcome the disadvantages of the prior art that the holding forceps cannot meet the minimally invasive requirements and the effect of bone removal and fixation is poor. [0004] In order to achieve the above object, the technical solution of the present invention is: a holder for a bone fixation plate, which mainly includes a handle and a...
