Intervertebral foramen puncture guide device

Abstract

The invention discloses an intervertebral foramen puncture guide device which comprises a vertical positioning device, a horizontal adjusting device and an angle adjusting device, wherein the vertical positioning device is connected with the horizontal adjusting device by a longitudinal-transverse rod connector; the angle adjusting device is connected with the horizontal adjusting device; an intervertebral foramen puncture sleeve is fixed on the angle adjusting device; and an intervertebral foramen puncture needle penetrates in the intervertebral foramen puncture sleeve. In the invention, based on the principle that two points define a straight line and through the guide of a zygopophysis puncture needle and the intervertebral foramen puncture needle sleeve, accurate intervertebral foramen puncture can be realized conveniently, accurately and quickly; only a little and simple X perspective is needed during the operation, and thus the ray exposure of the medical personnel and patients is reduced; and due to the guide of the zygopophysis puncture needle, the puncture blindness is avoided, the risk of vascular nerve tissue damage is reduced, the puncture accuracy and safety are guaranteed, the operation time is shortened, the device is easy to learn and understand, the learning period is shortened, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a guiding device for puncturing an intervertebral foramen. Background technique [0002] In recent years, more and more hospitals and doctors in China have used transforaminal endoscopy for spinal surgery, mainly for the lumbar spine. Transforaminal endoscopic surgery has the advantages of simple anesthesia (local anesthesia), small trauma (incision about 7mm), clear operative field (equipped with light source, display screen, camera system) and quick recovery (you can walk on the ground after surgery and be discharged on the same day). It has been recognized by more and more spine surgeons and patients. However, the learning curve is steep. Accurate puncture of the intervertebral foramen, establishment of the working channel and technique under the microscope are the two major difficulties in surgery. To a large extent, it determines the success of the operation an...

Problems solved by technology

The position and angle adjustment of the device mainly depends on the combined adjustment of the guide needle and the telescopic arm. The adjustment length of the telescopic arm is 14cm-20cm, and the length adjustment below 14cm cannot be realized; the telescopic arm has no rotation function, and the rotation adjustment cannot be realized; The guide needle is punctured through the guide needle hole. The small guide needle hole in the actual operation cannot guarantee the accurate puncture direction of the guide needle with a length of 20cm; the marking scale on the 2mm puncture needle and the 1.5mm guide needle is difficult to identify, and repeated operations cannot Ensure the high consistency of depth; the guide needle is not hollow, so anesthesia, angiography, and guide wire replacement cannot be directly performed; there is no alternative to the puncture needle, and non-invasiveness cannot be achieved; during the operation, it is often encountered that the puncture effect is not good and needs to be repeated Adjustment, the device has no backup solution, the telescopic arm has no rotation adjustment function, and the length adjustment below 14cm cannot be realized. Fine adjustment is not flexible and accurate, and the adjustment function is poor. Re-adjustment requires re-puncture; it increases damage and operation time, and it is not easy to operate quickly. carry out effectively
