Percutaneous puncture transverse balloon distraction percutaneous kyphoplasty surgical instrument

Abstract

The invention discloses a percutaneous puncture transverse balloon distraction percutaneous kyphoplasty surgical instrument. The instrument comprises a working bushing, a solid puncture needle core, a guide inner core bushing, a pre-bent elastic guide needle, a hollow soft drill and the like, wherein the solid puncture needle core is placed in the working bushing; after the solid puncture needle core is taken out, the guide inner core bushing can be placed in the working bushing; the pre-bent elastic guide needle is placed in the guide inner core bushing, can be arranged in the central hollow part by the hollow soft drill in a penetrating manner and is placed in the working bushing together with the pre-bent elastic guide needle; the pre-bent elastic guide needle can be arranged in the central hollow part in the penetrating manner through a hollow balloon pressurization system and the hollow balloon pressurization system is placed in the working bushing together with the pre-bent elastic guide needle. A conventional diagonally and eccentrically placed distraction balloon can be changed to be transversely and centrally placed to realize single-side puncture so as to achieve the purpose of full filling of bone cement; the height of anterior edge of the vertebral body can be more effectively restored, the operation time can be shortened, the amount of transmission ray in operation is reduced, and the kyphosis osteotomy of vertebral column is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a percutaneous puncture lateral balloon distraction kyphoplasty surgical instrument. Background technique [0002] Percutaneous puncture balloon distraction kyphoplasty (PKP), is to put the balloon into the vertebral body of osteoporotic compression fracture through vertebral body puncture, and pressurize to distract, take out the balloon and put the bone cement ( Polymethyl methacrylate) is injected into the cavity formed by distraction. After the bone cement solidifies, it can strengthen the fractured vertebral body and relieve pain. Surgical analgesic effect is obvious, and it is currently the mainstream treatment method for the treatment of senile osteoporotic vertebral compression fractures. [0003] In the traditional surgical method, the working sleeve is placed in the fractured vertebral body through percutaneous pedicle puncture under fluoroscopy...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the embodiment of the present invention is to provide a percutaneous puncture lateral balloon distraction kyphoplasty surgical instrument, which aims to solve the problems of bilateral puncture and distraction in traditional surgical methods, which are cumbersome and time-consuming, and the operator is exposed to radiation. The amount of puncture is large, the puncture is difficult, and it is easy to stray into the spinal canal to injure the nerve. Or unilateral puncture is performed, and the balloon is not placed near the midline. Remedial puncture on the opposite side is required, which prolongs the operation time and solves the problem of traditional oblique bracing. Opening, compression of the fracture part in front of the vertebral body is uneven, and the height of the front edge of the vertebral body and the correction of kyphosis are not ideal.
