Movable three-dimensional rocker arc-shaped guide spinal puncture assistor and use method of movable three-dimensional rocker arc-shaped guide spinal puncture assistor

Abstract

The invention relates to a movable three-dimensional rocker arc-shaped guide spinal puncture assistor, which comprises a ground movable support part, a three-dimensional rocker regulating part and an arc-shaped angle guide puncture part, wherein bottom feet of the ground movable support part are rolling wheels with brakes; a vertical rod which is sleeved by a round tube and is used for maintaining the integral balance is arranged above the ground movable support part; the three-dimensional rocker regulating part is of a three-dimensional regulating structure consisting of three rockers with screw threads and three extension rods, and also comprises a horizontal calibrator and a horizontal locking spanner; the arc-shaped angle guide puncture part comprises a 1 / 4 circular-arc rail with an angle, a rocker, two infrared fixed point instruments, a guide rod and a needle guide device; the rocker can realize 360-degree vertical rotation through regulating the circular-arc rail; the guide rail slides along the circular-arc rail; and the needle guide device can be dismounted for disinfection. The movable three-dimensional rocker arc-shaped guide spinal puncture assistor has the advantages that the puncture accuracy is high; the perspective time is short; the number of perspective times is small; the quantity of X-ray radiation received by medical care personnel and patients is low; the needle guide device can be disinfected and repeatedly used; and high molecular materials are radiotransparent, and the like. Therefore the movable three-dimensional rocker arc-shaped guide spinal puncture assistor can be widely applied to spinal surgeries such as intervertebral aperture mirror positioning puncture, epidural anesthesia, spinal tumor biopsy and spinal abscess puncture drainage.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a movable three-dimensional rocker arc-guided spinal puncture assistant and a use method thereof. Background technique [0002] Accurate positioning of the puncture is a necessary step in many spinal operations. If the positioning is not accurate, it will inevitably cause unnecessary damage to the rear structure of the spine, thereby increasing the damage. In particular, the positioning puncture of the lumbar 5 sacral 1 segment is particularly difficult because of the obstruction of the iliac crest and the transverse process. In the past, there was no positioning device, and only through repeated fluoroscopy can the implantation direction and depth of the guide wire be clarified. This method based solely on feeling is not accurate enough, and often requires extensive surgical experience and repeated fluoroscopy to complete it; it not only increases the operati...

Especially the positioning puncture of the lumbar 5 sacral 1 segment is particularly difficult because of the obstruction of the iliac crest and the transverse process. In the past, there was no positioning device. Only through repeated fluoroscopy can the implantation direction and depth of the guide wire be clarified.

This method based solely on feeling is not accurate enough, and often requires extensive surgical experience and repeated fluoroscopy to complete; it not only increases the operation time, but also exposes medical staff and patients to X-ray radiation for many times.
