Description
Technical Field
The utility model relates to a skull repairing buckle, and belongs to the field of medical appliances.
Background
The skull, which is used as a protecting cover for the brain of the human body, plays the most important role in life activities. It is counted that more than 300 thousands of patients with skull defects caused by traffic accidents and accidents are caused annually, and the skull defects are common sequela after injuries and operation of the patients with craniocerebral injuries. Since brain tissue is easy to be secondarily injured due to the loss of the shielding effect of normal skull, various symptoms and appearance influence can be caused by skull defect, a cranioplasty is often required, so that the intracranial pressure is restored to a normal stable state as soon as possible, and the influence of continuous serious damage and function of the brain caused by the brain defect is reduced by the daily severe change of the intracranial pressure, so that the cranioplasty is required as soon as possible. The skull repair mainly has the protection effect on brain tissues, and in addition, the skull cavity is restored to the closed cavity, so that the blood flow dynamics of the brain tissues at the defect part are improved. In a word, the cranioplasty has obvious effects on the recovery of plastic and nerve functions, and has great influence on the psychological, mental and recovery of patients.
However, titanium mesh for skull repair has a number of disadvantages: titanium mesh is a metallic foreign body and implantation in the body may create rejection and increase the chance of infection. Many of the cranioplasty procedures now use PEEK materials for repair, but titanium nails are still used to fix bone fragments or PEEK skull fragments. For design reasons, both the PEEK repair patch and the connecting piece have protruding portions, particularly protruding portions, compared to the skull bone, especially the titanium nail fixation portion. The titanium nails can give an alarm when passing the security check, which brings inconvenience to patients.
There is also a need in the clinic for a metal-free, protrusion-free, way of craniotomy fixation.
Disclosure of Invention
The utility model aims to provide a novel mode for fixing a skull sheet in the process of skull repair, which has the advantages of no metal material and no protrusion on the skull.
The skull repairing buckle comprises a bottom plate, wherein a mounting rod is arranged on the bottom plate; the mounting rod further comprises a clamping piece, and the clamping piece is adjustably fixed on the mounting rod through a locking structure;
the upper bottom plate and the clamping piece form a clamping groove for clamping the bone flap and a clamping groove for clamping the skull; the skull repairing buckle is made of polyether-ether-ketone materials.
Optionally, the base plate width is consistent with the width of the gap between the skull and bone flap.
Optionally, the locking structure is a threaded locking structure; the mounting rod is provided with threads, and the clamping piece is provided with screw holes.
Optionally, the locking structure is ribbon formula locking structure, be equipped with ribbon tooth on the installation pole, be equipped with on the card solid piece with ribbon tooth complex bundling belt buckle.
Optionally, the thickness of the bottom plate and the clamping piece is 0.8-1 mm.
The using method of the fixing buckle for the skull repair comprises the following steps:
step 1) trimming bone flap;
step 2) reducing the bone flap;
step 3) extending the bottom plate of the buckle into the bottoms of the skull and the bone flap along the gap between the skull and the bone flap; rotating the mounting rod; and then fixing the clamping piece with the mounting rod, so that the skull and the bone flap are clamped by matching the clamping piece with the bottom plate.
The utility model has the beneficial effects that:
the use is simple, the metal nails are not needed to fix, and meanwhile, no part of the skull is additionally protruded, so that the state of the heart of the postoperative patient is better.

Detailed Description
The present utility model is described in detail below with reference to examples, but the present utility model is not limited to these examples.
Example 1
Three drill holes are drilled firstly in the craniotomy process, then the bone is cut by a milling cutter, and the shape of the skull 1 and the bone flap 2 which need to be fixed is shown in figure 1. The fixing buckle for repairing the skull comprises a bottom plate 61, wherein a mounting rod 62 is arranged on the bottom plate 61; the mounting bar further includes a snap tab 63 adjustably secured to the mounting bar 62 by a locking structure. The locking structure can adopt a threaded matching structure or a ribbon type matching structureIn the structure, threads are adopted in the embodiment. And the width of the bottom plate is consistent with the width of the gap between the skull and the bone flap. The thickness of the bottom plate and the clamping piece is 0.8-1 mm 。
The using method of the fixing buckle for the skull repair comprises the following steps:
step 1) trimming bone flap;
step 2) reducing the bone flap;
step 3) extending the bottom plate of the buckle into the bottoms of the skull and the bone flap along the gap between the skull and the bone flap; the mounting bar is rotated approximately 90 deg. so that the bottom plate is perpendicular to the gap. And then fixing the clamping piece with the mounting rod, so that the skull and the bone flap are clamped by matching the clamping piece with the bottom plate. And finally removing the redundant part of the mounting rod.
While the utility model has been described in terms of preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the utility model, and it is intended that the utility model is not limited to the specific embodiments disclosed.
