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 Construction

[0016] Figure 1-Figure 2 A structure of the spinal closed puncture guiding instrument of the present invention is shown. The spinal closed puncturing guiding instrument is mainly composed of an angle ruler 1, a ruler 2, a puncture needle guide 3, a positioning needle needle guide 4, an aiming ruler 5, a puncture needle 6 and Composed of positioning pins 7, the angle ruler 1 is in the shape of a semicircle, and the ruler 2 vertically slides through the angle ruler 1, and its specific position is in the middle of the semicircle ring of the angle ruler 1, and can be adjusted The ruler 1 is locked, and the puncture needle guide 3 is provided with two parts, which are respectively slid to be located at the two ends of the angle ruler 1, and can be locked at any angle of the angle ruler 1. The two puncture needle guides 3 no matter from the angle Any angle of the ruler 1 guides the puncture needle 6 to reach the same point on the center line of the angle ruler 1, which is called th...

Abstract

The invention discloses a spinal closed puncture guide, which can be specifically used for the puncture positioning of various parts of the spinal column such as intervertebral foramen, intervertebral disc, articular process and pedicle. It consists of an angle ruler, a ruler, a puncture needle guide, a positioning needle needle guide, an aiming ruler, a puncture needle and a positioning needle, the angle ruler is in the shape of a semi-circle, and the ruler slides vertically through the angle ruler , and can be locked by the angle ruler, the puncture needle guide is provided with two pieces, which are respectively slid on both ends of the angle ruler, and can be locked at any angle of the angle ruler, the two puncture needle guides no matter from the angle Any angle of the ruler guides the puncture needle to the same point on the center line of the angle ruler. The positioning needle needle guide is provided with two pieces, one is fixed on one end of the ruler, and the other is slid on the other side of the ruler. One end can be locked, and the positioning needle guide device guides the positioning needle to stick to the bone near the patient's lesion.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a spinal closure puncture guide. Background technique [0002] The closed spine puncture 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 important n...
