Disposable hard-plastic nerve root retractor with independent light source and attracting capacity

Abstract

The invention discloses a disposable hard-plastic nerve root retractor with an independent light source and an attracting capacity. The nerve root retractor comprises a handle and a first connecting rod, the handle is coaxially connected with the first connecting rod, two first baffles are installed at the end, far away from the handle, of the first connecting rod, a second connecting rod is arranged between the first baffles, the second connecting rod is provided with a hinge pin penetrating through the first baffles, and the second connecting rod can rotate around the first connecting rod; a sleeve is installed at the end, far away from the first baffles, of the second connecting rod, a third connecting rod is arranged in the sleeve in an inserted mode, a sleeve joint telescopic rod is arranged in the sleeve through a mounting base, and the sleeve joint telescopic rod is connected with the third connecting rod. The disposable hard-plastic nerve root retractor with the independent light source and the attracting capacity is easy to operate and convenient to use, a doctor can manually operate the nerve root retractor to enable the retractor to be retracted or stretched, the stretching precision of the retractor is improved, a vacuum device can extract excessive hydrops, and treatment is prevented from being affected due to excessive hydrops.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable hard plastic strip with an independent light source that can attract nerve roots. Background technique [0002] Nerve root retractor is a necessary instrument in the operation of removing nucleus pulposus of lumbar intervertebral disc herniation. In order to visualize the herniated disc, the compressed nerve root must be retracted to the opposite side of the operation. During the operation, if the distance between the nerve root is insufficient, the nerve root and the herniated intervertebral disc cannot be well separated, and the doctor's surgical field is not fully exposed, and accidental injury may occur during the operation. The nucleus pulposus poses great difficulties. In the process of operation, special retractors are needed to attract, which increases the manpower load. Traditional nerve root retractors do not have lighting devices, and there will ...

AI Technical Summary

Problems solved by technology

During the operation, if the distance between the nerve root is insufficient, the nerve root and the herniated intervertebral disc cannot be well separated, and the doctor's surgical field is not fully exposed, and accidental injury may occur during the operation. The nucleus pulposus poses great difficulties

In the process of operation, special retractors are needed to attract, which increases the manpower load. Traditional nerve root retractors do not have lighting devices, and there will be a lot of bleeding during the long-term operation, which will affect the postoperative effect; traditional nerve root retractors can only be adjusted manually by doctors. position, the adjustment accuracy is not high, and it will damage the patient's body. Therefore, we propose a disposable hard plastic belt with an independent light source that can attract nerve root retractors.
