A spine positioning frame

Abstract

The invention discloses a spine positioning frame. The existing thoracolumbar surgery positioning steps are cumbersome, and patients and medical staff are greatly exposed to radiation from the C-arm machine. The four transverse dividers of the present invention are all fixed to the frame body, and the frame body is divided into five marking areas along the longitudinal direction; in each marking area, two symmetrical anti-line protrusions are fixed on the longitudinal frames on both sides of the frame body. The two symmetrically arranged convex strips are fixed by connecting rods; the longitudinal partition strips are located in the five marked areas, and each of the five marked areas is fixed with a marked pattern frame; the longitudinal frame of the frame is set in each marked area. There is a chute that forms a sliding pair with the corresponding line protrusion, and the chute is arranged along the longitudinal direction of the frame; the teeth on the top of each line protrusion and a gear form a gear pair; the gear is hinged on the frame through a rotating shaft, and Part of the gear teeth are exposed outside the frame. The present invention uses a C-arm machine to perform one irradiation to accurately locate; the marking pattern frame can clearly identify the corresponding marking area; and the alignment convex line can be fine-tuned by rotating the gear.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a spine positioning frame clinically used in preoperative positioning for thoracolumbar surgery. Background technique [0002] Thoracic and lumbar surgery is a common type of spine surgery in orthopedics. The advantage of minimally invasive spinal surgery is that the incision is small, and accurate preoperative body surface positioning is very important for minimally invasive spinal surgery. If the positioning is not accurate, the incision will inevitably be prolonged , thereby increasing damage. At present, the most commonly used method of spinal positioning clinically is the Kirschner wire positioning method. However, due to the limited fluoroscopy field of view of the Kirschner wire positioning method, only 2 to 3 vertebral bodies can be used, and the transverse, coronal, and sagittal planes are irradiated multiple times with the diseased vertebra as the center, and the C-ar...

Problems solved by technology

[0005] The purpose of the present invention is to provide a spine positioning frame for clinical application in preoperative positioning of thoracolumbar surgery for the existing thoracolumbar surgery positioning steps are cumbersome, and patients and medical staff are exposed to relatively large radiation from C-arm machines. The structure of the spine positioning frame is simple. The spine positioning frame is used for positioning before thoracolumbar surgery. The positioning is convenient. The C-arm machine can accurately position after one irradiation, which shortens the operation time and reduces the radiation damage to patients and medical staff.
