Mechanical separation arm for neck surgery

Abstract

The invention discloses a neck surgery mechanical separation arm which comprises a base; a clamping mechanism fixed to a surgical bed is arranged on the base; a rotating platform is arranged at the upper end of the base; a lifting mechanism is arranged at the upper end of the rotating platform; a horizontal telescopic mechanism is arranged on the lifting mechanism; and an operation head is arranged at the end of the telescopic mechanism; two horizontal first threaded rods are movably arranged in the operating head; a first push block and an L-shaped second push block are arranged on the heads of the two first threaded rods respectively; the first push block and the second push block are attached to each other; extension rods extending downwards are arranged on the first push block and the second push block respectively; and blocking pieces are arranged at the ends of the extension rods; and a clamping ring for fixing the ultrasonic probe is arranged on the extension rod. A surgeon inserts the blocking piece in front of the neck of a patient, then pushes away important tissues such as blood vessels, tracheas and esophagi and establishes a safe operation area, and the surgical risk can be effectively controlled by shortening the surgical time and enhancing the stability of the surgical environment.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a mechanical separation arm for neck surgery. Background technique [0002] Cervical disc herniation is a common and frequently-occurring disease. The main cause is that on the pathological basis of cervical disc degeneration, the outer annulus fibrosus of the intervertebral disc ruptures, and the nucleus pulposus tissue further protrudes (or protrudes) and compresses the nerve root or spinal cord. As a result, clinical symptoms such as neck, shoulder and upper limb pain, numbness and weakness of limbs and even paralysis appear. Endoscopic anterior transvertebral bone tunnel technique is a new technique for the treatment of cervical disc herniation. Compared with traditional surgery, this technique has obvious advantages such as less trauma, less bleeding, lower cost, and faster recovery. [0003] It is an important step of this technology to establish a bone tunnel...

AI Technical Summary

Problems solved by technology

[0004] However, a safe operating area must be established in the neck through the body surface before establishing a bone tunnel, otherwise the operation will easily damage the carotid artery / vein or esophagus / trachea, and the consequences will be extremely serious

In the past, the two-finger method was used to establish a safe operating area, requiring the surgeon or assistant to maintain the operating area with at least one hand throughout the entire process. Not only is the surgical space smaller, but the operation is more difficult; It is very easy to cause blood circulation and soreness, which leads to the continuous decline in the stability of the fingers, and it is difficult to control the risk of surgery

More importantly, the safety of the operating area established by using fingers cannot be fully guaranteed, and it is not completely sure whether the carotid sheath and visceral sheath are completely separated, which will lead to increased surgical risks
