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...
