Description

Spherical feeler hook capable of being cut

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a can cut spherical hook of visiting.

Background

As a common disease and frequently encountered disease in orthopedics, degenerative diseases of the spine (such as cervical/lumbar disc herniation, cervical/lumbar spinal stenosis, lumbar spondylolisthesis and the like) not only cause disability and life quality reduction of patients, but also cause great economic burden to families and society. For severe degenerative spinal related diseases, surgery is an important means of treatment, with the success of spinal decompression being an important safeguard for efficacy.

The current common method is to remove the bony structures (spinous process and vertebral lamina) of the lesion part, explore and properly release by adopting a feeler hook, then use a gun-type rongeur or nucleus pulposus pincers to remove the ligamentum flavum and scar tissues, or use a spherical feeler hook to pick up the ligamentum flavum or scar tissues and then use a sharp blade to cut off the ligamentum flavum and the nerve root, thereby achieving the effect of reducing the pressure of the dural sac and the nerve root. However, the soft tissues such as ligamentum flavum, etc. are often thickened and adhered to the dural sac and the nerve root, and the dural sac is often torn or ruptured and even the nerve root is damaged in the decompression process of the gun-type rongeur or the nucleus pulposus pincers. When the feeler hook and the sharp knife are used for matching pressure reduction, the pressure reduction process is often complicated and unsafe due to the small operation space, the increase of operation steps and the like.
