Abstract

The invention provides a knob assembly and a circular tube type anastomat with the knob assembly. The knob assembly comprises a knob body, and a slow threaded part and a locating plate detachably arranged in the knob body, wherein the locating plate is matched with the knob body so as to fix relative positions of the slow threaded part and the knob body. Compared with the prior art, the knob assembly and the circular tube type anastomat with the knob assembly are more convenient to assemble.

Description

technical field [0001] The invention relates to a knob assembly and a round tubular stapler provided with the knob assembly, belonging to the technical field of medical instruments. Background technique [0002] The round tube stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract. Most of this type of stapler adopts the axial inward binding method. During the anastomosis, the two sections of tissue are restrained and a circular anastomotic ring is formed inside the tissue. Tissues heal relatively easily. [0003] Conventionally, a circular tubular stapler includes a stapler body, an operating handle movably connected to the stapler body, and an anvil assembly matched with the body. The stapler body includes an annular staple cartridge and a cutting knife arranged at the distal end. The anvil assembly includes a conical anvil, an anvil cap fixed on the top of the anvil, a knife anvil arranged inside the anvil, an...
