A kind of cranial flap reduction fixation clip

Abstract

The invention discloses a skull flap restoration fixing clamp which comprises a lock catch, an internal tooth path, an external tooth path and a fixing plate, wherein the external tooth path is vertically arranged on the fixing plate, the lock catch is provided with the internal tooth path, the internal tooth path and the external tooth path are detachably clamped together, and the lock catch is detachably arranged on the external tooth path through the internal tooth path and plays a restoration fixing function. When the fixing clamp is used, a matched fixing tool does not need to be used, the operation is simple and convenient, the skull gap can be completely covered, and the skull flaps or the fracture plates seldom protrude out, loose or deform; the internal tooth path and the external tooth path are detachably clamped together, therefore, if complications occur, the fixing clamp can be repeatedly used and conveniently taken out, and the skull flap restoration fixing clamp has great clinical significances

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a medical device, in particular to a cranial flap resetting and fixing clamp which reduces the steps of resetting and fixing the cranial flap for medical personnel, effectively covers the bone suture, and fixes the cranial flap well. Background technique [0002] In recent years, with the continuous improvement and refinement of neurosurgery, the reduction and fixation technology of skull flap in neurosurgery is also constantly updated. The implementation of this technology can not only protect the brain tissue, maintain the volume and pressure of the normal cranial cavity, but also It also has the effect of maintaining the complete shape of the head, which reduces the patient's fear of surgery. The materials used in this technology have also developed from the initial medical glue, silk thread or steel wire to the current titanium alloy connecting piece, absorbable conne...

AI Technical Summary

Problems solved by technology

The materials used in this technology have also developed from the initial medical glue, silk thread or steel wire to the current titanium alloy connecting piece, absorbable connecting piece, skull lock of various materials, etc., although the current fixing devices and materials are basically solved. However, most of the fixation devices still require matching fixation tools, the operation time is long, the skull space cannot be covered, and the fixation materials cannot be reused and taken out if complications occur. more difficult issues
