Puncture location device for minimal invasive lumbar surgery

Abstract

The invention relates to a medical device, in particular to a puncture positioning device for minimally invasive surgery of the lumbar spine. It includes a positioning ring, a positioning needle and a puncture needle; the positioning ring is a fan-shaped device with a central angle of 105°, a number of positioning reference holes are equidistantly arranged on the positioning ring, and a limited depth locking device is provided at the end of the positioning ring, and the positioning needle can be pierced The over-limit depth locking device is fixed on the positioning ring; the positioning pin includes a positioning rod and a fixing rod, one end of the positioning rod is a needle head, and the fixing rod is uniformly provided with a concave ring in the transverse direction. The puncture positioning device for minimally invasive surgery of the lumbar spine provided by the present invention has precise positioning and short positioning time.

Description

technical field [0001] The invention relates to a medical device, in particular to a puncture positioning device for minimally invasive surgery of the lumbar spine. Background technique [0002] Lumbar disc herniation is a common cause of low back pain and a common clinical disease. Traditional treatment methods are prone to recurrence and have many long-term complications. In addition to surgery and conservative treatment, minimally invasive treatment is the direction of future development in the treatment of lumbar disc herniation. The key to minimally invasive treatment of lumbar disc herniation lies in the accuracy of puncture positioning and the safety of the treatment process.

Problems solved by technology

[0003] At present, when performing positioning puncture in minimally invasive lumbar surgery, the first step for beginner physicians is difficult: use a soft guide needle to puncture from the side and rear of the waist, place it on the upper articular process of the lumbar spine according to a certain angle, and then place each Level working channel; in this process, positioning usually takes 40 minutes to 150 minutes, the patient is painful, it is difficult to persist in the operation for a long time, and the puncture position may not be ideal, which increases the difficulty of the operation

And when the positioning is inaccurate, repeated punctures are required, which not only easily causes surgical accidents, but also increases the possibility of surgical complications (bleeding, infection, narrowing of the gap, nerve damage, etc.). Radiation projections cause immeasurable harm to patients and doctors. How to improve the positioning accuracy of lumbar minimally invasive surgery puncture has become an urgent technical problem in this field.
