Clinical application of spine posting frame in preoperative position of lumbar surgery

Abstract

The invention discloses a clinical application of a spine posting frame in preoperative position of a lumbar surgery. The present lumbar surgery requires complicate position and great radiation is caused to a patient and medical workers by a C arm machine. The clinical application of the spine posting frame in preoperative position of the lumbar surgery comprises the following steps of aligning a longitudinal separation bar of the posting frame to a middle line of a patient spine, moving the C arm machine to the posting frame to irradiate to project a patient lesion position, a frame body, a transverse separation bar, the longitudinal separation bar, an alignment projected bar and each sign pattern frame, synchronously rotating gears on two sides of a sign area when the lesion position is determined by an image and the sign area where the lesion position memorized by different sign pattern frame, driving corresponding alignment projected bars to move to drive a connection rod to move to an accurate lesion position, and marking the lesion position on the patient skin via a marking pen. Accurate position can be achieved via one time irradiation of the C arm machine; sign areas can be clearly identified by the corresponding sign pattern frames; and the alignment projected bars can be micro-adjusted via rotation of the gears.

Description

technical field [0001] The invention belongs to the field of medical appliances, and in particular relates to the clinical application of a spine positioning frame 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 ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a clinical application of a spine positioning frame in the 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 the C-arm machine. 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.
