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
[0005] At the same time, in the prior art, the level is fixed on the instrument or the base, and the human body surface or the aseptic area of ​​the operation is not smooth, so it is very difficult and time-consuming to obtain the level. It is necessary to readjust the level and readjust the parameters, which is time-consuming and laborious

Embodiment 1

[0035] A method of spinal puncture positioning, using the protruding lumbar intervertebral disc in transforaminal endoscopic surgery as the puncture target, to illustrate the method of puncture positioning, the steps are as follows:

[0036] 1. Determine a surgical puncture channel from the body surface to the deep lesion in the body, that is, the line connecting the needle entry point on the body surface and the target point, which is the puncture path. Mark the needle entry point on the body surface as point C, and the lesion on the lumbar intervertebral disc The bulge is the target point, and the target point is marked as point O, and the line CO between the two points is the puncture path; CO is an invisible line segment in three-dimensional space, which is in most cases in line with the sagittal plane, transverse plane, and Both the cut plane and the coronal plane have a certain angle, so it is very difficult for the blind puncture needle to accurately reach the target.

Embodiment 2

[0043] like figure 1 and figure 2As shown, a spinal puncture positioner includes a positioning ruler 1, an angle ruler 2, a correction magnet 4, and a detachable level 3. The angle ruler 2 is a semicircle, and an installation hole 5 is provided at the center of the chord. The positioning ruler 1 and the puncture catheter 7 are fixed at the installation hole 5 through the angle lock switch 6, and both can rotate around the center of the circle; The included angle of the puncture catheter 7 is 0°, at this time, the central axis of the puncture catheter 7 is consistent with the central axis of the positioning ruler 1; the puncture catheter 7 is fixed while the positioning ruler 1 is fixed using the angle lock switch 6, thereby adjusting the needle insertion angle of the puncture catheter 7 When the angle lock switch 6 is fully released, the puncture catheter 7 can be disassembled and separated from the angle ruler 2, so that the puncture catheter 7 is left on the puncture needl...

Embodiment 3

[0049] Such as image 3 As shown, a spinal puncture positioner includes a positioning ruler 1, an angle ruler 2, a correction magnet 4, and a detachable level 3. The angle ruler 2 is a semicircle, and an installation hole 5 is provided at the center of the chord. The positioning ruler 1 and the puncture catheter 7 are fixed at the installation hole 5 through the angle lock switch 6, and both can rotate around the center of the circle; The included angle of the puncture catheter 7 is 0°, at this time, the central axis of the puncture catheter 7 is consistent with the central axis of the positioning ruler 1; the puncture catheter 7 is fixed while the positioning ruler 1 is fixed using the angle lock switch 6, thereby adjusting the needle insertion angle of the puncture catheter 7 When the angle lock switch 6 is fully released, the puncture catheter 7 can be disassembled and separated from the angle ruler 2, so that the puncture catheter 7 is left on the puncture needle alone, an...

Abstract

The invention discloses a spinal puncture positioning method and device. The device includes a positioning ruler, an angle ruler, a correction magnet, a detachable level, and may also include a height gauge. The spinal puncture positioning method is simple and only needs to measure two The angle and depth of the puncture path can be obtained by numerical values. Based on the method, the puncture positioner has a simple structure, is convenient for production and maintenance, and is easy to operate. It can be used for real-time positioning during surgery. Convenient, quick and accurate puncture positioning, easy to re-puncture to locate the target. Small in size, easy to sterilize, high-temperature disinfection does not affect the accuracy of the instrument, does not occupy the space of the operating table, and does not pollute the operating area. Its positioning principle and design can be widely applied to various deep positioning operations in the body and the development and research of various special positioners.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a spinal puncture method and device. Background technique [0002] The spinal puncture positioner 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. [0003] 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. [0004] However, the target or operation area in the deep spine is extremely small, su...
