Abstract

The invention relates to the technical field of medical appliances, in particular to a precise bone nailing device for an orthopedic internal fixation surgery. The device comprises a fixing frame, a fixing cross rod, a support vertical rod and a chassis. The fixing frame is composed of an upper fixing frame and a lower fixing frame which are connected by a fixing frame hinge. The support verticalrod is composed of an upper support vertical rod and a lower support vertical rod, the fixing cross rod passes through the lower support vertical rod, and the top end of the upper support vertical rodis fixedly connected with a support cross rod fixedly connected with a chassis sliding rod. The outside walls of the two fixing frames are provided with sliding slots, the sliding slots are providedwith a movable positioning ruler, a sliding positioning block is provided with a positioning cylinder penetrating the positioning block through a positioning sliding slot. The bone nailing device is reasonable in structure design. The fixing frame can be used for fixing the fracture part of a patient, the sliding positioning block can be moved to the appropriate position by means of matching of amain positioning ruler and the sliding positioning block, and screws can be accurately nailed into the positions to be fixed by using the principle of three points and one line.

Description

Technical field [0001] The invention relates to the technical field of medical appliances, in particular to a precise bone nail device for orthopedic internal fixation operations. Background technique [0002] Fracture refers to the complete or partial fracture of the continuity of the bone structure. After the fracture is reset, it is prone to re-displacement due to instability. Therefore, measures must be taken to fix it in a suitable position to gradually heal. Common fixation methods include internal fixation. Fixation and external fixation, of which internal fixation is through surgical incision and fixation with steel plates, steel needles, intramedullary needles, screws, etc. In the Chinese invention patent with the announcement number CN104622552A, an orthopedic restoration nail device was published, which directly adjusts the alignment of the fracture end through the restoration of the bone nail, which is accurate, stable and reliable, and can effectively shorten the ope...
