Vertebroplasty body surface positioning navigating instrument

Abstract

The invention discloses a vertebroplasty body surface positioning navigating instrument. The instrument comprises a base which can be fixed to an operating table / DSA machine tool, a main rod which is connected to the base and has lifting motion relative to the base, a main rod upper cover, a threaded rod which adjusts the lifting of the main rod, an angle fixing ring which is embedded in the main rod and rotates relative to the main rod, a locating rod which is connected to the angle fixing ring and has a concertina movement relative to the angle fixing ring and a locating ring which is connected to the locating rod and has a rotary movement relative to the locating rod; a groove is formed in the inner side of the base, and the length and the width of the groove are matched with those of a connecting rod of the side face of the operating table / DSA machine tool; the vertebroplasty body surface positioning navigating instrument is cheap in design and can be sterilized, accurate positioning of pedicle of vertebral arch can be conducted by an external mechanical type navigating instrument which is applied to an operation, operative complications can be reduced, operative difficulties can be lowered, operative learning curves can be reduced, and the therapeutic efficiency is improved.

Description

technical field [0001] The invention belongs to the medical field, and relates to techniques such as vertebral body fracture vertebroplasty, X-ray navigation, mechanical navigation and the like, in particular to a body surface positioning navigator for vertebroplasty. Background technique [0002] 1. Background of vertebroplasty [0003] Vertebral fracture is a kind of orthopedic disease with high incidence clinically. Including traumatic vertebral fractures, osteoporotic fractures, bone diseases, bone tumors and vertebral fractures caused by bone metastases. Vertebral fractures are usually treated conservatively and surgically. Minor non-displaced fractures can be treated conservatively with bed rest, while more displaced or compressed fractures require surgical treatment. [0004] The incidence of this disease is high in the elderly, especially vertebral fractures caused by osteoporotic vertebral fractures and bone metastases. Patients often cannot tolerate the anesthes...

Problems solved by technology

[0016] The purpose of the present invention is to address the deficiencies in the prior art and provide a body surface positioning navigator for vertebroplasty, mainly aimed at the pedicle caused by empirical vertebral body puncture under the C-arm X-ray machine or DSA machine. , nerve root, spinal cord, and dura mater injuries; according to the experience of clinical vertebroplasty surgery, it is transformed into a machine; a cheap, sterilizable, and intraoperatively applied in vitro mechanical navigator is designed to accurately position the pedicle puncture ; To reduce surgical complications, reduce surgical difficulty, and reduce surgical learning curve, improve treatment efficiency
