Puncturing positioning device of operation of intervertebral foramen of lumbar vertebra and using method thereof

Abstract

The invention discloses a puncturing positioning device of operation of intervertebral foramen of lumbar vertebra and a using method thereof, and belongs to the field of medical instruments. The operation puncturing positioning device comprises an operation bed fixing clamp, an upright column which is perpendicular to a bed surface is connected with the fixing clamp, the end of a cross bar is slidably connected with the upright column, the other end of the cross bar is a rotary shaft, an adjusting rotary tube is rotatably connected with the rotary shaft, a positioning tube which is perpendicular to the axial center of the rotary shaft is arranged on the side, close the end, of the adjusting rotary tube, a positioning needle is arranged in the positioning tube, a horizontal length measuringbar and a tilting length measuring bar are arranged on a rotary shaft and an adjusting rotary tube which are located on the side of the positioning tube, arc-shaped long holes which are formed in therotary direction are formed in the outer circumference of the adjusting rotary tube, and the arc-shaped long holes move along the horizontal length measuring bar when the adjusting rotary tube is rotated. By means of the puncturing positioning device, the puncturing direction and angle can be accurately positioned, the operation time can be shortened, the smooth processing of the operation is ensured, the pain of a patient is relieved, and the overstrain of a doctor is reduced.

Description

technical field [0001] The invention relates to a surgical positioning device and a using method thereof, in particular to a lumbar intervertebral foramina puncture positioning device and a using method thereof, belonging to the field of medical instruments. Background technique [0002] For operations on the spinal column such as lumbar disc herniation, the traditional lumbar disc herniation nucleus pulposus removal operation is an open operation, which will bring great pain and trauma to the patient, and the recovery period is long and the wound healing is slow. [0003] In recent years, with the development of science and technology, it has become a common method to perform spinal surgery under the condition of minimal trauma by using endoscope. The puncture point and the correct puncture direction are the key to the success of the operation, and the incidence of postoperative complications will also be significantly reduced. Generally, during the operation, the patient n...

Problems solved by technology

[0015] Since the fixed head tilt or tail tilt angle α and forward tilt angle β degrees are determined in the air, the exact angle cannot be determined, and the puncture position from outside the patient's skin cannot be determined. In most cases, the positioning and orientation are based on experience. , there is a certain risk

[0016] Although there are also some tools for determining the forward tilt angle, due to the complex structure, the operation is cumbersome and difficult to master, and it takes too long to use, which is not conducive to shortening the operation time and reducing the pain of the patient. The simple and practical puncture positioning device is Medical devices urgently needed in spinal endoscopic surgery
