A cranial fracture repair device suitable for clinical neurosurgery

Abstract

The invention discloses a clinical broken skull repairing device used in the neurosurgery department. The clinical broken skull repairing device comprises a U-shaped titanium alloy clamping groove andan L-shaped titanium alloy clamping groove, wherein the top of the left side of the U-shaped titanium alloy clamping groove is provided with a round through groove, a clamping column is slidingly connected in the round through groove, a supporting column is located on the right side of the round through groove and connected with the right side of the U-shaped titanium alloy clamping groove through a rotary shaft, the left end of the supporting column is provided with a round clamping groove, the right end of the clamping column is clamped and connected in the round clamping groove, the side face of the supporting column is in sleeved connection with a foldable titanium alloy net through a through hole, and the left side and the right side of the foldable titanium alloy net are both connected with the mutually close sides of the U-shaped titanium alloy clamping groove and the L-shaped titanium alloy clamping groove through rotary shafts. The clinical broken skull repairing device usedin the neurosurgery department can have certain extensibility, does not affect skull development, meanwhile can keep the rigidity of the repairing device, thus protects the head and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cranial fracture repair device suitable for clinical neurosurgery. Background technique [0002] Craniotomy is required for any reason. After the skull flap is removed, it cannot be replanted in situ immediately. It can be preserved by subcutaneous autologous embedding. Although the autologous skull group has fewer complications and satisfactory repair appearance, it requires reoperation and increases the patient's life expectancy. It is painful, and there are shortcomings of skull resorption and even necrosis, which lead to loosening and unstable fixation. If the operation of autologous skull preservation can be simplified, the environmental requirements for autologous skull preservation can be reduced, and the autologous skull can be used without deformation. Implantation will be the best cranioplasty, and the open cranioplasty repair device used clinically in neurosu...

Problems solved by technology

[0002] Craniotomy is required for any reason. After the skull flap is removed, it cannot be replanted in situ immediately. It can be preserved by subcutaneous autologous embedding. Although the autologous skull group has fewer complications and satisfactory repair appearance, it requires reoperation and increases the patient's life expectancy. It is painful, and there are shortcomings of skull resorption and even necrosis, which lead to loosening and unstable fixation. If the operation of autologous skull preservation can be simplified, the environmental requirements for autologous skull preservation can be reduced, and the autologous skull can be used without deformation. Implantation will be the best cranioplasty, and the open cranioplasty repair device used clinically in neurosurgery is not perfect for cranial repair, because there are many conditions for cranial repair, such as cranial fracture, missing cranium and cranial bone Collapse, etc., but it is best to use its own skull group. At present, most of them use titanium alloy mesh for repair directly. For the overall skull repair, the existing skull repair devices all have the extension of the repair device. The resistance is not good enough, it is extremely easy to affect the development of the head, or it has stretchability, but the rigidity of the repair device is reduced, and the head cannot be better protected in the event of a collision, which is not conducive to use
