UBE surgical tools-nerve stripper

Structural features and advantages
Advantages of multi-angle design
Combination of 5 and 15 degrees: This nerve dissector has a 5-degree angle on one end and a 15-degree angle on the other. The 5-degree angle is suitable for use when the nerve is closely adhered to the surrounding tissue but needs to be finely separated. Because the smaller angle can be closer to the surface of the nerve, it can be gently inserted between the nerve and the adhesion tissue without damaging the nerve for preliminary separation. The 15-degree angle is used when the separation range needs to be slightly expanded or when the adhesion tissue is relatively tough. It can provide greater dissection force, and because the angle is relatively moderate, it can still be accurately operated in the complex anatomical structure of the spine to avoid damaging nerves and other important tissues.
Combination of 15 and 25 degrees: The nerve dissector has a 15-degree angle on one end and a 25-degree angle on the other end, which is more flexible when facing different degrees of adhesion and different surgical scenarios. The 15-degree angled end can be used for general nerve stripping operations, such as separating adhesions between nerve roots and protruding disc tissue or ligamentum flavum during spinal surgery. The 25-degree angled end is more effective in dealing with more complex adhesions, such as adhesions of scar tissue around nerves caused by long-term lesions. The larger 25-degree angle can better cut into thicker adhesion tissue, helping doctors to separate nerves more efficiently.
Advantages of fine operation
Both nerve strippers are designed to facilitate fine operation in UBE surgery. Their head angle design allows doctors to flexibly choose the appropriate angle for stripping according to the specific situation of the tissue around the nerve. In spinal surgery, nerve tissue is very fragile, and this fine operation tool can accurately separate nerves from surrounding tissue and reduce the risk of iatrogenic nerve injury. For example, in cervical or lumbar disc herniation surgery, the nerve stripper can accurately separate the nerve root from the protruding nucleus pulposus tissue or surrounding adhesion tissue along the direction of the nerve root.
Application scenarios in UBE surgery
Application in disc herniation surgery
In UBE surgery for lumbar disc herniation or cervical disc herniation, the nerve stripper is used to separate the adhesion between the nerve root and the protruding nucleus pulposus tissue. For earlier disc herniation, the adhesion is relatively mild, and the 5-degree and 15-degree combination of nerve strippers can play a good role. Use the 5-degree angle end to first separate the loose adhesion between the nerve and the nucleus pulposus along the edge of the nerve root, and then use the 15-degree angle end as needed to further expand the separation range to create good conditions for nucleus pulposus removal. In some chronic disc herniation cases with severe adhesion, the 15-degree and 25-degree combination of nerve strippers is more suitable. The 25-degree angle end can cut into thicker adhesion tissue, effectively strip the nerve root from the protruding nucleus pulposus and surrounding scar tissue, and relieve the compression of the nerve root.
Application in spinal canal decompression surgery
In UBE surgery for spinal stenosis, the nerve stripper can be used to separate the nerve tissue in the spinal canal from the surrounding compressive tissue, such as the yellow ligament, bone hyperplasia, etc. In cervical or lumbar spinal canal decompression surgery, when dealing with the hypertrophic yellow ligament of the posterior wall of the spinal canal, the 15-degree angled nerve stripper (either of the two models) can gently pull away the spinal cord or nerve root below the yellow ligament, and then use the end with the appropriate angle (selected according to the adhesion situation) to separate the adhesion between the nerve and the yellow ligament to prevent damage to the nerve during the removal of the yellow ligament. For lateral recess stenosis caused by bone hyperplasia on the lateral wall of the spinal canal, the nerve stripper can also help separate the nerve from the bone, providing safety for subsequent bone removal operations.
Application in spinal trauma surgery
In traumatic surgeries such as spinal fractures and dislocations, the nerve stripper can be used to inspect and protect nerve tissue. For example, in surgeries with thoracic fractures and the risk of spinal cord injury, the nerve stripper can carefully explore the situation around the spinal cord before fracture reduction and fixation, and separate the bone fragments or hematoma tissue that may compress the spinal cord from the spinal cord. According to the specific adhesion situation, choose the end with the appropriate angle for operation, such as using the 15-degree angle end for preliminary separation first, and switching to the 25-degree angle end when encountering thicker adhesions to ensure the safety of the spinal cord.
Operation precautions and skills
Operation precautions
High requirements for visualization operation: UBE surgery relies on endoscopic visualization. Before using the nerve stripper, it is necessary to ensure that the endoscopic field of view is clear and accurately judge the relationship between the stripper and the surrounding tissues such as nerves and blood vessels. Any blind operation may lead to serious consequences such as nerve damage.
Principle of gentle operation: Due to the fragility of nerve tissue, the principle of gentleness must be followed during the operation. When inserting and using the nerve stripper, avoid excessive force to prevent damage to the nerves. Especially when the nerves are already under compression or damage, be more careful in operation.
Angle selection and conversion: According to the degree of adhesion between the nerve and the surrounding tissue and the specific surgical scenario, the angle of the nerve stripper head should be reasonably selected. During the operation, if it is found that the current angle is difficult to effectively separate the adhesion tissue or may damage the nerve, it is necessary to carefully switch to another angle for operation, and pay attention to the endoscopic image to ensure safe operation.
Operation skills
Insertion skills: According to the anatomical path and nerve position observed by the endoscope, slowly insert the nerve stripper at an appropriate angle and direction. During the insertion process, its delicate structure should be used to carefully enter the area around the nerve along the natural anatomical gap or the established working channel to avoid forced insertion and damage to the surrounding tissue. For example, in anterior cervical spine surgery, when inserting the nerve stripper, you can first follow the gap at the front edge of the vertebral body, and then slowly adjust the direction to approach the nerve root.
Stripping skills: When stripping the nerve from the surrounding tissue, use gentle and continuous movements. First, fully contact the head of the stripper with the surface of the nerve or the edge of the adhesion tissue, and then slowly apply the stripping force according to the selected angle. The direction of the stripping should be determined according to the anatomical direction of the nerve and the requirements of the surgical operation. Generally, the stripping is performed along the natural extension direction of the nerve to avoid twisting or over-bending the nerve. At the same time, the real-time observation of the endoscope should be combined to flexibly adjust the strength and angle of the stripping according to the reaction of the nerve and the changes in the surrounding tissue.
