Absorbable cranial fixation lock system and method of use

Abstract

The present invention relates to the technical field of medical instruments, and in particular, to an absorbable skull fixing lock system and a method of using same. The absorbable skull fixing lock system includes an absorbable skull fixing lock and a locker. The absorbable skull fixing lock system may be used by means of correct implantation of the absorbable skull fixing lock, and pre-locking and final locking of the absorbable skull fixing lock. The present invention is easy to operate and needs no additional instrument in a skull fixation operation; the present invention is quick and timesaving, and thus reduces the operation time; due to the elliptical design of a locking surface, the locking surface is more reliable and safer; due to the toothed design of the locking surface, no shift occurs, so that a lock body is safer and does not slip off; by means of a fixing pin, it is ensured that two lock plates can be center-aligned when the two lock plates are locked, and the alignment is good; a force limiting valve is designed to ensure that the lock body is safer, and ensure that the locking force applied to each lock body by a doctor when locking the fixing lock is the same.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an absorbable skull fixation lock system and its application method. Background technique [0002] Cranial fixation is a necessary process in neurosurgery. The existing cranial fixation methods generally use nails and plates, and the material is generally titanium alloy. During the operation, drilling and tapping operations are cumbersome and time-consuming, while absorbable Nails and plates are easily broken due to the small size of the screws, resulting in failure of the operation. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an absorbable skull fixation lock system and a method of use, which can realize safe, reliable and convenient skull fixation. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The abs...
