This spinal probe is a practical tool for spinal canal exploration in UBE surgery. The spherical porous handle delivers a comfortable grip. Its hollow design cuts down weight to avoid hand fatigue during long operations, and it stays non-slip even with sweaty palms. The slim, smooth shaft easily fits the narrow dual-channel incision. Surgeons use it to retract soft tissue and touch nerve roots, quickly locating osteophytes and adhesions to check lesions. Made of stainless steel, it resists disinfectants and can be sterilized repeatedly.
