Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to a multi-angle laser positioning device for spinal puncture and an operation method. BACKGROUND

[0002] Lumbar disc herniation (LDH) is a common degenerative spinal disease, and in recent years, it has shown a high incidence rate and a trend of younger age. There are many treatment methods for lumbar disc herniation, including open surgery, minimally invasive intervention, and conservative treatment. Radiofrequency thermocoagulation (RFTC) is a commonly used minimally invasive intervention method for treating LDH in clinical practice. Radiofrequency intervention treatment has fewer complications, less trauma, definite efficacy, and can be repeated, and is more suitable for elderly patients, and has become an effective means for relieving severe degenerative spinal pain in clinical practice.

[0003] In RFTC and other surgeries involving spinal puncture, accurate puncture is crucial. Currently, there are many deficiencies in the clinical puncture guidance method. Although CT guidance can provide a certain degree of accuracy, it often needs to rely on equipment to measure the angle after plain scanning to implement puncture, which undoubtedly significantly increases the radiation dose received by the patient. DSA and C-arm guidance mainly estimate the puncture angle through preoperative prone position CT images, but due to the difference between the preoperative position and the actual treatment position, the angle deviation problem is difficult to avoid. At the same time, when using DSA and C-arm guidance, it is often necessary to repeatedly advance the puncture needle for angle adjustment under the conditions of fluoroscopy or multiple anteroposterior and lateral exposure, until the predetermined position is reached. This process not only significantly prolongs the operation time, making the patient bear more radiation hazards, but also repeatedly punctures, which can easily cause muscle spasm and other conditions, thereby interfering with the needle angle, reducing the accuracy and safety of puncture, and increasing the risk of surgery and patient pain.

8. A method for spinal puncture, comprising the multi-angle laser positioning device for spinal puncture as described in any one of claims 1 to 7, characterized in that: Includes the following steps: Step 1: Place a positioning pad on the CT, DSA, C-arm, or other diagnostic and treatment bed, keeping it parallel to the bed. The patient lies prone on the positioning pad with the waist flattened. Use a contrast screen to expose and locate the lesion point in the positive position and draw the lesion point. Step 2: Place a 20mm steel ball at the anteroposterior lesion location point as a reference, apply a positioning needle to the puncture point, and perform lateral positioning exposure; through two exposures, measurements can be taken on CT, DSA, and C-arm equipment (distance measurement function) to measure the lateral distance from the lesion to the puncture point on the body surface, and determine the distance from the puncture point of the radiofrequency ablation needle to the lesion location from the anteroposterior position; at the same time, measure the angle B between the puncture point of the needle and the plane where the fixation frame (20) is located; Step 3: In the angle calculation module, the lateral distance from the lesion location to the puncture point on the body surface is a, the distance from the lesion location to the front side of the patient's skin is b, and the angle between the puncture needle and the horizontal direction is A. Furthermore, ∠A = arctan(a / b); Step 4: Fix the multi-angle laser positioning device on the operating table (45) using the fixed frame (1) and the position adjustment mechanism, and adjust the position of the fixation frame (20) to ensure that the sliding block (23) is in a horizontal state. After obtaining angle A and angle B, adjust the position of the adjustment track (26). When adjusting the angle between the plane of the adjustment track (26) and the plane of the fixation frame (20), the scale on the observation indicator scale corresponding to the front side wall of the sliding block (23) is angle B. Slide the sliding frame (33) and observe the scale corresponding to the puncture scale (32) through the observation hole (34) to find that it is angle A. Step 5: Turn on the cross laser light (21). The cross projection position of the cross laser light (21) is the same as the puncture point and is projected onto the end of the puncture needle. The puncture direction is the position where the beam of the cross laser light (21) is emitted. During the puncture process, the position of the cross projection is detected in real time by the visual monitoring device (35). When the cross projection deviates, an alarm is triggered by the alarm on the display screen (16).
