Problems solved by technology

The combination of spinal surgery technology and imaging technology has led to a certain degree of development in positioning technology during surgery. Intraoperative fluoroscopy has become a routine method for surgical positioning. However, the traditional positioning method has complicated operations, inaccurate positioning, and increased repeated projections. Due to the shortcomings of operation time and radiation exposure of patients and medical staff, the important development trend of spinal surgery is minimally invasive surgery. Minimally invasive surgery has the advantages of small trauma, small scars, satisfactory curative effect, and fast recovery. Small, especially requires the accuracy of positioning, accurate positioning is the premise to ensure the smooth implementation of the operation and shorten the operation time

Embodiment 1

[0014] Embodiment 1: The positioning device for spinal surgery proposed by the present invention consists of longitudinal fences 1 and positioning symbols 3 . Wherein positioning symbol 3 has many pieces, and has different shapes, and many pieces (triangle, rectangle, heart shape, crescent, cross, polygon) positioning symbol 3 of various different shapes are evenly distributed and welded on the longitudinal fence 1. The various shapes of the positioning symbol 3 can be easily identified, so that the corresponding position can be accurately determined.

[0015] The positioning device is used as follows: after the patient is anesthetized, the patient is placed and fixed according to the position required for the operation (the patient’s prone position is used as an example below), the X-ray machine perspective positioning direction is left and right projection, and the positioning device is placed vertically On one side of the patient's body, X-rays are used for fluoroscopy. Aft...

Embodiment 2

[0017] Embodiment 2: The positioning device for spinal surgery proposed by the present invention consists of a longitudinal fence 1 , a horizontal fence 2 , and symbols 3 . Wherein the positioning symbol 3 has a plurality of pieces, and has different shapes (triangle, rectangle, heart shape, crescent, cross, polygon, rhombus, concentric circle), wherein a plurality of longitudinal fences 1 and a plurality of horizontal fences 2 are equally spaced, The spacing can be 0.5cm, the longitudinal fence 1 and the horizontal fence 2 are interwoven and welded together to form a grid, and multiple positioning symbols 3 of various shapes are evenly distributed and welded on the connection points of the longitudinal fence 1 and the horizontal fence 2 superior. The various shapes of the positioning symbol 3 can be easily identified, so that the corresponding position can be accurately determined.

[0018] The positioning device is used as follows: after the patient is anesthetized, the pat...

Abstract

The invention belongs to the technical field of medical apparatus, and in particular relates to a set of spinal surgical positioning device, which consists of longitudinal railings, transverse railings and positioning symbols. The spinal surgical positioning device is characterized in that: the longitudinal railings and the transverse railings are fixedly connected two by two to form a grid structure, and the positioning symbols are positioned at connecting positions among the longitudinal railings and the transverse railings; or two transverse railings are provided, the two ends of each longitudinal railing are connected with the two transverse railings to form a structure like a Chinese character 'mu' meaning eyes respectively, and the positioning symbols are positioned on the longitudinal railings, wherein the plurality of positioning symbols have different shapes and are distributed and welded on the railings uniformly. The positioning symbols can be identified conveniently due to the different shapes, thereby judging a corresponding position accurately. The spinal surgical positioning device is simple in structure, accurate in positioning and convenient in use, and can meet the requirement of spinal surgical positioning.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a positioning device for spinal surgery. Background technique [0002] Intraoperative positioning in spinal surgery is the key to ensure the accuracy of the surgical segment and the success of the operation. The combination of spinal surgery technology and imaging technology has led to a certain degree of development in positioning technology during surgery. Intraoperative fluoroscopy has become a routine method for surgical positioning. However, the traditional positioning method has complicated operations, inaccurate positioning, and increased repeated projections. Due to the shortcomings of operation time and radiation exposure of patients and medical staff, the important development trend of spinal surgery is minimally invasive surgery. Minimally invasive surgery has the advantages of small trauma, small scars, satisfactory curative effect, and fast recovery. The...
