Skull flap reset connection fixing device and manufacturing method thereof

Abstract

The invention relates to a skull flap reset connection fixing device, which comprises a flat sheet and post bodies, wherein the materials of the flat sheet and the post bodies are high polymer materials; the flat sheet is arranged in the horizontal direction; the post bodies are symmetrically arranged on the lower surfaces of the two horizontal ends of the flat sheet; the bottoms of the two post bodies are inwards collected relative to the inside; the inward contraction angles are respectively 10 to 90 degrees. The fixing device has the advantages that the skull flap can be stably connected and fixed for a long time for resetting; the problem of affecting magnetic resonance examination after the connection and fixation by using the conventional titanium connecting sheets and titanium nails can be solved; meanwhile, the skull flap reset connection fixing device is also suitable for children patients; the use is convenient; safety and effectiveness are realized.

Description

technical field [0001] The invention belongs to the technical field of medical device production and manufacturing, in particular to a skull flap reduction, connection and fixation device and a manufacturing method thereof. Background technique [0002] Neurosurgery craniotomy requires the use of a craniotomy drill to drill a hole at a suitable position on the skull, and then uses a matching craniotomy miller to separate the skull flap, and then resects the lower layer of the skull, and then needs to reset the skull flap. Need to be properly fixed. At present, the products used for cranial flap reduction and fixation include titanium connectors and titanium nails. In addition, there are also titanium skull locks used by clinical surgeons, but the skull lock is divided into two pieces, and the part facing the dura mater may occasionally stimulate and damage the epidural blood vessels or other tissues, causing local bleeding or abnormal discharge. In recent years, although t...

Problems solved by technology

In addition, there are also titanium skull locks used by clinical surgeons, but the skull lock is divided into two pieces, and the part facing the dura mater may occasionally stimulate and damage the epidural blood vessels or other tissues, causing local bleeding or abnormal discharge. In recent years, although the combined fixation method of titanium connecting piece and titanium nail is more troublesome, and it will affect MRI examination to varying degrees, its usage is more than that of cranial lock
