Problems solved by technology

Repeated puncture and multiple fluoroscopy increases the patient's pain and X-ray radiation, prolongs the operation time, increases the risk of surgery and the possibility of infection, and even repeated puncture positioning may not necessarily be able to obtain the ideal target position, thereby significantly reducing the risk of injury. Surgical efficacy

Embodiment approach

[0038] Figure 4 — Figure 10 A second embodiment of a spinal minimally invasive guide is shown, and the spinal minimally invasive guide is mainly composed of a grid, a ruler plate 1 , a guide B5 , a drill sleeve 3 , and a puncture needle 4 .

[0039] The puncture needle 4 also includes a Kirschner wire and a drill bit, and the drill sleeve 3 includes a Kirschner wire drill sleeve, a puncture needle drill sleeve and a drill bit drill sleeve.

[0040] The guide B5 is provided with a base 51, a dial B52 and a guide sleeve B53. The base 51 stands on the ruler plate 1 and can slide relative to the ruler plate 1. The front side of the base 51 is in contact with the ruler plate 1. The front side of the board 1 is parallel, and the dial B52 is arranged on the base 51, and can swing and lock relative to the base 51. The angle of the front and rear swing is provided with an indicating scale A521 on the dial B52. The angle of swing is the degree of the longitudinal puncture angle. The...

Abstract

The invention provides a minimally invasive guider for spines. The guider consists of a grid, a ruler, guider bodies, a drill bush and a puncture needle, and is used for guiding of spine puncture. Before surgery, the grid is stuck to the surface of skin; a puncture point and a puncture angle on the skin are determined by computerized tomography (CT) imaging; during the surgery, the ruler is attached to the surface of the skin, and a guider body is placed on the ruler, and the angle of the guider body can be adjusted longitudinally and transversely relative to the ruler to make a puncture direction and angle fit in with a puncture line, and thereby, the goal of puncture guiding is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a spinal minimally invasive guide. Background technique [0002] The minimally invasive spinal guide is used for the puncture positioning of a certain target point in the deep spine in the body, specifically for the puncture positioning of various parts of the spine such as intervertebral foramen, intervertebral discs, articular processes, and pedicles. With the development of clinical departments such as minimally invasive spine surgery, endoscopic spine surgery, pain department and neurology, many minimally invasive operations need to be guided by puncture needles to reach the target point, surgical lesion or surgical channel, such as transforaminal surgery , Percutaneous pedicle screw fixation, radiofrequency ablation of intervertebral disc, nerve root block anesthesia, etc. However, the target or operation area in the deep spine is extremely small, surrounded by many impor...
