Embodiment Construction

[0030] The present invention discloses an auxiliary device for a circular tube binding instrument, in particular a guide for guiding a circular tube binding instrument into the body, specifically the embodiment shown in the figure.

[0031] The circular tube type bookbinding instrument of prior art, as Figure 5 As shown, it includes a round tube 7, an anvil assembly, a nail cartridge assembly and a nail barrel for accommodating the nail cartridge assembly at the far end of the round pipe 7, and is movably arranged in the nail barrel and used to communicate with the nail barrel. The anvil pull rod 9 connected to the anvil assembly. The staple cartridge assembly includes a staple cartridge 3 and staples placed in the staple cartridge, as well as a cutter 11 and a staple push piece movably arranged inside the staple cartridge 1, and the distal end of the staple cartridge 3 is the staple cartridge surface , opposite to the anvil surface of the anvil assembly. The cutter 11 is i...

Abstract

The invention provides a hollow truncated cone-shaped guide element which comprises a near end, a far end and an outer wall connected with the near end and the far end. The external diameter is gradually enlarged from the far end to the near end, one group of splicing blocks are fixedly spliced to form the guide element, all the splicing blocks are connected in a penetrating manner by the same traction part, the guide element is disintegrated when pulled by external force according to the order from far to near, and a splicing block string connected by the traction part is finally formed and can be separated from a circular tubular bookbinding instrument. The guide element has the advantages that the guide element can be extracted from the circular tubular bookbinding instrument once, is convenient to operate and fixedly arranged at the far end of a staple cartridge component, the largest external diameter of the guide element is equal to the external diameter of a staple cylinder, the overall external diameter of the staple cylinder cannot be increased, and the difficulty of the circular tubular bookbinding instrument entering human tissues is reduced.

Description

technical field [0001] The invention relates to an operation auxiliary instrument of a circular tube binding instrument, in particular to a guide piece of a circular tube binding instrument. Background technique [0002] The circular tubular stapler is a surgical instrument widely used in circular tubular tissue suturing operations. It is composed of a circular nail head assembly and a firing assembly; two sections of circular tubular tissue that need to be connected are placed in the nail head assembly Between the staple anvil and the staple cartridge, adjust the distance between the staple anvil and the staple cartridge to gradually clamp the tissue, and then operate the firing assembly to shape the nail and complete the connection of the two sections of tissue. [0003] In the actual operation, there are two types of operations where it is difficult for the circular tube-type stapler to enter the pipeline, namely, low rectal surgery and gastric bypass surgery. The first ...
