Abstract

The invention relates to the technical field of a medical treatment device, and particularly to an absorbable skull fixing lock system and a using method thereof; the absorbable skull fixing lock system comprises an absorbable skull fixing lock and a locker; through correct implantation of the absorbable skull fixing lock, pre-locking of the absorbable skull fixing lock and the final locking, the use of the absorbable skull fixing lock system can be realized. The absorbable skull fixing lock system is simple in operation of skull fixing operation and needs not any machine; the absorbable skull fixing lock system rapidly saves time and saves operation time; due to an ellipse design of the locking face, the locking face is more firm and safer; the tooth-shaped design of the locking face is free from displacement, thus the locker effect is safer and cannot slip off; two locking plates can be aligned to the center through the fixing pin when two locking plates are locked, and the alignment is good; the design of a force limiting valve can guarantee safer fixing of lock body, and guarantee the same big locking force of a doctor to every lock body by locking the fixing lock.

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...
