Abstract

The invention provides a guiding sheathing canal which comprises a handle, a conveying pipe and a bending control wire, and the handle is provided with a first inner cavity and a second inner cavity; the first end of the handle is fixedly connected with a first position on a pipe body of the conveying pipe; the conveying pipe comprises an inner layer and an outer layer, and the conveying pipe is of a foldable expansion structure; the first end of the conveying pipe penetrates through the first inner cavity, and the conveying pipe is attached to the inner cavity wall face of the first inner cavity. The conveying pipe is provided with a third inner cavity, and the third inner cavity is communicated with the second inner cavity; the first end of the bending control wire is fixedly connected to the second end of the conveying pipe, the bending control wire is attached to the inner layer of the conveying pipe and penetrates through the third inner cavity and the second inner cavity, and the second end of the bending control wire is fixedly connected with the handle. According to the invention, the trafficability of the guiding sheath tube in a human body can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guide sheath. Background technique [0002] Nowadays, in surgical operations or inspections, introducing sheaths are usually used to dilate and support blood vessels, so as to establish a working channel for doctors to perform treatment. is the area that needs treatment, and treat it. [0003] In the prior art, the guiding sheath used in the operation is a straight pipe, and the guiding sheath is a single-cavity structure that can only pass through a single instrument. When large-sized medical instruments need to be transported, it is necessary to expand the guiding The access size of the sheath can lead to vascular complications. In addition, due to the hard material used for the tube, the passage of the introducer sheath in the human body is poor. SUMMARY OF THE INVENTION [0004] The purpose of the embodiments of the present invention is to provide an introducer ...
