Abstract

The invention provides a guiding device and a circular tube type binding device with the same. The guiding device is provided with a guiding part and a positioning part which are integrally arranged, wherein the guiding part is provided with a smooth first outer surface with a guiding-in function, a hollow first cavity and a first inner surface exposed in the first cavity, and the outer contour of the guiding part is in a contracting shape from a near end to a far end. The positioning part is connected in the first cavity, the first inner surface is provided with a spiral first groove, a second inner surface is provided with a spiral second groove, the guiding part can be dragged to be gradually disassembled in a spiral shape along the first groove, and the positioning part can be dragged to be gradually disassembled in a spiral shape along the second groove. The guiding device has the advantages that the guiding part and the positioning part are integrally arranged, the guiding device can be disassembled to be in a strip shape and dragged out of the circular tube type binding device in one time, and operation is convenient.

Description

technical field [0001] The invention relates to a guiding device and a circular tube binding instrument with the guiding device, belonging to the technical field of medical instruments. 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 type ...
