Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] see figure 1 , is a structural schematic diagram of a medical operating sheath provided in an embodiment of the present invention, including a main body 1, a first curved tube 2 and a first elastic membrane 3; 1 through; the first curved tube 2 is an integrally formed hollow pipe, such as image 3 As shown, it includes a first bending...

Abstract

The embodiment of the invention discloses a medical operation sheath comprising a main body. The main body is provided with a bend pipe; the bend pipe is provided with a plurality of bend joints; the bend joints are arranged in the middle of the main body; adjacent bend joints are connected with each other; the bend joints on two ends of the bend pipe are respectively connected with the main body. The bend joints can deform, so the outer wall of one side of each bend joint stretches and deforms due to external pressure on the bend pipe and the outer wall of the other side produces compression deformation, and the bend pipe can bend; the bend joints are mutually connected with each other and affect each other, so much internal elasticity can be counteracted and rebounding can be prevented; and the bend pipe can bend to meet a human body pipeline with small or little contact pressure, so operation can be facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical operation sheath of a medical body cavity pipeline inserter. Background technique [0002] In laparoscopic urinary system surgery, such as tumor resection and stone treatment, it is often necessary to perform endoscopic treatment or place ureteral stents in the ureter or renal pelvis during or after the operation. For endoscopic treatment or placement of ureteral stents, it is necessary to place an operating sheath as an operating channel before the operation. [0003] In the prior art, the tube body of the operating sheath is mostly a plastic tube body, such as an infusion tube, etc. When the curvature of the pipeline in the human body is large or complicated, it is difficult to enter the tube body of the operating sheath; and the tube body of the operating sheath is in the After entering the pipeline in the human body, due to the elasticity of the tube it...
