Positionable skull defect protection device

Abstract

The invention provides a positionable skull defect protection device, and belongs to the technical field of medical instruments. The device comprises an afterbrain fixing assembly, an afterbrain clamping sleeve assembly, an ear clamping assembly, a positioning protection assembly and a protection bag, and a main body structure is made of an elastic resin material; two groups of telescopic connecting sleeves capable of stretching out and drawing back automatically in the afterbrain clamping sleeve assembly are arranged in telescopic positions in the afterbrain fixing assembly in a bilateral symmetry mode, and the size can be adjusted according to the brain and the head of different sizes;rotatable ear clamping assemblies are arranged at the two ends of the telescopic connecting sleeve respectively, and the ear clamping assemblies can be clamped behind ears on the two sides of the head and can be rotationally adjusted according to different clamping sizes; a protection main sleeve in the positioning protection assembly is connected into the afterbrain fixing assembly from back to front, a plurality of groups of protection connecting sleeves can be connected into the protection main sleeve, each group of protection connecting sleeves can be provided with protection bags with different sizes, the protection bags can be positioned at corresponding positions according to different defect positions of the head, and the device has the advantages of being light in weight, convenient and fast to operate and good in air permeability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positionable skull defect protection device. Background technique [0002] Skull defects are common in postoperative patients after traumatic decompression, skull comminuted fractures, and skull tumors. Skull repair can correct the skull defect syndrome and cosmetic problems caused by skull defects, and protect brain tissue from damage. [0003] The effective protection of the head after the repair of the skull defect has a great relationship with the degree of postoperative rehabilitation. The general protective device for skull defect is to cover the defect with a hard shell with soft material, and then use gauze in the shape of a net bag to cover the hard shell on the head, or set up a comprehensive protective inflatable and water-filled material The hood is used to cover the head as a whole for protection. [0004] As disclosed in the prior art (CN 111297563 A), a...

Problems solved by technology

[0004] As disclosed in the prior art (CN 111297563 A), a protective device for skull defects includes a hood, a first airbag, and a silicone cover. The first airbag and the silicone cover are all located on the inner wall of the hood, and the silicone cover is fixed On the front side of the first airbag, a plurality of air holes are uniformly opened on the side wall of the hood, a rubber pad is fixed on the side of the first airbag away from the silicone cover, and a second rubber pad is fixed on the side away from the first airbag. Threaded pipe, the end of the second threaded pipe away from the rubber pad extends to the outside of the hood through the air hole and is threaded with a sealing pipe, and the sealing pipe is fixed with the first air pipe, and the end of the first air pipe away from the hood is sequentially installed with an exhaust device And the one-way valve, the skull defect is protected by the airbag and the silicone cover on the hood. However, although the overall hood has air holes, compared with traditional gauze, its air permeability will be lower. Worse, at the same time, an external air pump and other inflatable equipment is required, the operation is cumbersome, and because the inflated amount cannot be accurately grasped, it is very easy to cause secondary damage to the repaired skull
