Description

Technical Field

[0001] The invention relates to the field of medical technology, in particular to a venous sinus flexible stripping device for neurosurgery. Background Art

[0002] A vein stripper is a surgical tool that can be used to treat varicose veins. It consists of a handle and a cutting head. The cutting head is a sharp metal instrument that removes a portion of the vein. The handle is usually ergonomically designed to make it easier for the doctor to operate, and vein strippers can reduce surgical and recovery time, as well as reduce pain and discomfort after the procedure.

[0003] The main structure of the vein stripper is usually made of stainless steel or medical-grade titanium alloy to ensure the durability and biocompatibility of the device. The main body may be designed in a ring or snake shape to adapt to the tortuous path of the vein. This part of the structure is installed in a circle on the bracket in the box when stored. Since the main body of the vein stripper is flexible, it may be placed out of place due to deformation during storage, which requires time and effort to place it again.

[0004] To this end, we provide a flexible venous sinus stripping device for neurosurgery to solve the above problems. Summary of the invention
