Problems solved by technology

However, when the circular stapler is actually used for surgery, the operator may accidentally hold the operating handle when the distance between the anvil assembly and the staple cartridge does not reach the proper position, resulting in false firing, resulting in surgical failure. may even lead to medical malpractice

Embodiment Construction

[0047] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0048]In order to solve the technical problems in the prior art, the present invention provides a round tubular stapler, which includes a stapler body, wherein the stapler body includes The nail pushing rod, the nail pushing piece and the nail cartridge assembly arranged in turn at the distal end, the proximal end of the nail pushing piece includes at least one firing piece, the stapler body also includes an anvil shaft, and t...

Abstract

The invention provides a round tube type stapler. The round tube type stapler includes a stapler body; the stapler body includes a nail cabin assembly, a nail-pushing piece, a nail-pushing rod and a nail anvil shaft; the near end of the nail-pushing piece is provided with a firing piece; the near end of the firing piece is provided with a warped part; and the nail anvil shaft is provided with a fixing part. Through the adopting of the round tube type stapler, the fixing part matched with the firing piece is located at a first position area when the distance between a nail anvil assembly and anail cabin does not reach a proper position, the nail-pushing rod is not linked to the nail-pushing piece, and the nail-pushing rod cannot push the nail-pushing piece even if an operation handle is held, so that firing by mistake cannot be caused; and the fixing part is located at a second position area when the nail anvil assembly moves to the proper position, the nail-pushing rod can be linked to the nail-pushing piece, and the nail-pushing rod can push the nail-pushing piece to fire if the operation handle is held at the moment. Thus, under the premise of guaranteeing the normal working ofthe nail-pushing rod and the nail-pushing piece, firing by mistake can be prevented when operations are not ready, so that the safety of the using of instruments can be enhanced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a round tube stapler. Background technique [0002] Gastrointestinal disease is one of the diseases with high incidence in human beings. In the course of treatment, a circular stapler is often used instead of the doctor's manual operation to anastomose physiological tissues such as the digestive tract. The circular tubular stapler is a common surgical instrument, most of which use the axial inward binding method to form end-to-end or end-to-side anastomosis on physiological tissues such as the esophagus, stomach, and intestinal tract during surgery. The segmental tissue is retracted and accommodated in the stapler. After firing, a circular anastomosis is formed on the tissue, and the human body channel is reconstructed. [0003] In the prior art, a circular tubular stapler includes a stapler body, an operating handle movably connected to the stapler body, and an anvi...
