A biopsy forceps with support function

Abstract

This utility model relates to a biopsy forceps with a support function, including a handle assembly, a forceps head assembly, a slip ring, a cable, a support tube assembly, and a spring tube assembly. The rear end of the support tube assembly is detachably connected to the handle assembly. The spring tube assembly passes through the support tube assembly, with its rear end fixedly connected to the front end of the handle assembly, and its front end extending out of the support tube assembly and fixedly connected to the forceps head frame of the forceps head assembly. When the spring tube assembly is compressed axially, it can undergo compression deformation. After gripping the target tissue, the forceps head assembly can be compressed along with the spring tube assembly and retracted into the support tube assembly. The front end of the support tube assembly presses against the tissue near the forceps head assembly to separate the target tissue from other tissues. The support tube can support the surrounding tissue, allowing the biopsy forceps to stably grip and separate the target tissue, improving surgical efficiency and avoiding tissue tearing caused by pulling operations.
