Abstract

The invention belongs to the technical field of percutaneous vertebroplasty, and specifically comprises a bilateral percutaneous puncture vertebral body guider, the bilateral percutaneous puncture vertebral body guider comprises a bottom plate and a mounting plate rotationally mounted on the bottom plate, a positioning plate is mounted on bottom plate, first sliding grooves are formed in the bottom plate, a second sliding groove is formed in the first sliding groove, first guide mechanisms are slidably mounted on the two sides of the positioning plate and located in the first sliding grooves,the first guide mechanism comprises a first mounting base, a first angle ring is mounted on the first mounting base, a first preformed groove is formed in the first mounting base, a first adjusting wheel is rotationally mounted in the first preformed groove, a first guide cylinder is radially arranged in the first adjusting wheel in a penetrating manner, a first fastening stud is provided with a first rotary knob, a first fixing frame is provided with a first fixing base, the first adjusting wheel is fixedly provided with a first positioning column, and the first positioning column is arrangedin the first fixing base in a penetrating mode and used for solving the problem that medical staff and patients need to make contact with rays repeatedly due to the fact that the number of times of fluoroscopy in an operation is large.

Description

technical field [0001] The invention belongs to the technical field of percutaneous vertebroplasty, in particular to a bilateral percutaneous puncture vertebral guide. Background technique [0002] Percutaneous vertebroplasty (PVP) refers to the percutaneous injection of bone cement into the vertebral body through the pedicle or outside the pedicle to increase the strength and stability of the vertebral body, prevent collapse, relieve pain, and even partially recover A minimally invasive spine surgery technique for the purpose of vertebral body height. [0003] At present, for percutaneous puncture vertebral body shaping, it is necessary to repeatedly fluoroscopy to locate the puncture point and puncture abduction angle during the operation. The number of times of fluoroscopy during the operation is large, which leads to repeated contact between medical staff and patients and radiation, which is not conducive to medical staff and patients. the health of the patient.
