The invention provides an ejector pin rod and a circular tubular anastomat provided with the ejector pin rod. The circular tubular anastomat comprises an anastomat body, an anvil component and an operating handle which is connected with the anastomat body in a pivot way; the ejector pin rod is provided with an initial position and a triggering position; the operating handle can drive the ejector pin rod to move from the initial position of the ejector pin rod to the triggering position of the ejector pin rod; the circular tubular anastomat also comprises a banking pin which is connected with the anastomat body in the pivot way; the banking pin comprises an initial position and a secondary triggering prevention position; an ejector pin rod bulge is formed in the ejector pin rod; when the banking pin is positioned at the initial position, the ejector pin rod bulge is arranged between the operating handle and the banking pin; and when the banking pin is positioned at the secondary triggering prevention position, the banking pin is arranged between the ejector pin rod bulge and the operating handle. Compared with prior art, the ejector pin rod can provide the function of effectively preventing secondary triggering, so that medical accidents are avoided.
Description
technical field [0001] The invention relates to a screw pusher rod and a circular tube stapler provided with the screw pusher rod, 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] Currently, a circular-tube stapler for treating hemorrhoids 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 arrang...
