Description

Working sleeve for spinal endoscope

Technical Field

The utility model relates to a technical field is diagnose to backbone scope specifically is a backbone is work sleeve pipe for endoscope.

Background

The spinal endoscope is a tube equipped with a light, which enters the intervertebral foramen from the side or the lateral back of the patient body (can be in a flat and oblique way), and performs an operation in a safe working triangle area. The operation is carried out outside the intervertebral disc fibrous ring, the protruded nucleus pulposus, the nerve root, the dural sac and the proliferated bone tissue can be clearly seen under the direct vision of an endoscope, then the protruded tissue is removed by using various grasping forceps, the bone is removed under the endoscope, and the damaged fibrous ring is repaired by using the radio-frequency electrode. The technical key points are that the working sleeve is placed in a disc through an intervertebral foramen approach under the guidance of a C-arm image or placed in a vertebral canal after intervertebral foramen forming, the operation under the endoscope is completed, the fixing and decompression range of tissues around the long path is limited, the working sleeve is easy to hold during the operation, but the operation under the endoscope enters a target area layer by layer according to anatomical structures to complete decompression along with the change of the interventional operation of the spinal endoscope through the intervertebral foramen and the intervertebral foramen approach to a surgical endoscope operation mode, particularly the application of the cervical and lumbar spinal stenosis at the back, the tissue structure at the back is relatively thin, the fixed path of the working sleeve is short, and the windowing or the unilateral approach bilateral decompression between the back vertebral plates is added, the range of the bone window expansion is relatively larger, the working end of the working sleeve cannot be fixed, so that the holding of the working sleeve in the endoscope operation becomes a challenge. The art field appears for operation under the mirror in the soft tissue around the work sleeve mouth of pipe front end is pushed away through the axial rotation, the apparatus passageway of backbone scope, camera system, light source system and business turn over water passage are stock form coaxial arrangement, backbone scope extends in the pipe along work sleeve in the operation, the apparatus stretches out the operation under the coaxial visual completion mirror of mirror mouth, the apparatus axial depth, the accurate control of rotation angle all needs to use backbone scope as the fulcrum, backbone scope needs to use work sleeve as the fulcrum, just can accomplish the safe accurate operation of instrument under the mirror, especially the power grinds the operation of boring window decompression sclerotin and is more so, work sleeve's controllable core that becomes the safe accurate operation of scope that becomes.

The working cannula is basically controlled by hands in the previous spinal endoscope operation, an assistant holds the working cannula by hands, 1.5-2 hours are needed for a cervical and lumbar spinal canal minimally invasive operation, the thoracic spinal canal is narrow even for more than 3 hours or longer, the working cannula is very hard to hold in the whole precise operation under the endoscope, and both an operator and the assistant are challenged by physical strength and endurance; the control of the working cannula in the operation is completely controlled by an assistant and an operator, the working cannula is easy to slip out of control under excessive fatigue, and potential huge risks are formed on the spinal cord and nerve roots in front of the orifice; because the spinal endoscope needs to be rotated to adjust the angle and the visual field during operation, in the prior art, the angle is adjusted by holding and rotating the handle, and the mode can aggravate fatigue in operation for several hours and also has potential risks.
