Description

Technical Field

[0001] The utility model relates to the field of digestive endoscope sheath tubes, in particular to a digestive endoscope sheath tube curvature control and protection device. Background Art

[0002] Digestive endoscopy plays a crucial role in the diagnosis of early-stage digestive tract tumors, as well as bile duct and pancreatic diseases. It allows direct observation of structural changes in the digestive tract wall and, through optical magnification and microscopic staining, reveals subtle structural changes in small mucosal lesions. During routine digestive endoscopy, the sheath portion of the endoscope near the handle must be bent, creating bending pressure. High bending pressure can easily cause the sheath portion of the endoscope near the handle to buckle, leading to a high maintenance rate for the endoscope. The Chinese utility model patent with application number 201920648130.4 discloses a control handle of an ultra-fine electronic endoscope system with a guiding function, comprising a handle shell, and a sheath angle control assembly is provided on the upper part of the handle shell; a controllable bending angle sheath is fixedly inserted into the handle shell along the longitudinal direction, and the front end of the controllable bending angle sheath extends from the lower end of the handle shell, and the end of the controllable bending angle sheath is fixedly connected to the main end of the Y-shaped tube; an endoscope insertion connector is fixedly provided on the top of the handle shell, and a Luer interface is formed at one end of the endoscope insertion connector, and the endoscope insertion connector is connected to a rotary damping member through this end; the other end of the endoscope insertion connector is connected to the first branch end of the Y-shaped tube; the endoscope insertion connector has a channel that can be connected to the first branch of the Y-shaped tube; the channel formed by the endoscope insertion connector and the rotary damping member is used to pass the ultra-fine electronic endoscope body.

[0003] The control handle of the aforementioned ultra-thin electronic endoscope system can control the bending angle of the front end of the controllable bending angle sheath tube. However, it cannot protect the sheath tube near the handle from bending, and the problem of excessive bending pressure on the sheath tube causing it to break still occurs. Utility Model Content

[0004] In response to the deficiencies of the prior art, the present invention provides a curvature control and protection device for the sheath of a digestive endoscope, which can wrap and protect the sheath portion near the handle and resist bending, effectively solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for controlling and protecting the curvature of a digestive endoscope sheath, comprising a sleeve with upper and lower openings, the sleeve as a whole being a conical structure with a larger upper portion and a smaller lower portion, a lateral notch being provided on one side of the sleeve, the notch passing through the sleeve up and down, and a tensioning structure being provided at the upper and lower ends of the outer side of the notch respectively.

[0006] As a preferred technical solution, the tensioning structure includes a C-shaped fixing frame embedded in the sleeve, and rectangular grooves connected to the fixing frame are provided on the sleeve on both sides of the notch. The fixing frame in the left rectangular groove is hinged to the left end of the pull plate through a hinge shaft, and a wedge-shaped first clamping block is provided on the inner side of the right end of the pull plate.

[0015] 3. The utility model provides a vertically shapeable connecting piece through the annular interval between the upper and lower fixing frames in the sleeve body. The upper and lower ends of the connecting piece are fixedly connected to the fixing frames respectively. When in use, the connecting piece can connect the two fixing frames together and is shapeable, thereby limiting the bending angle of the bending part of the endoscope body, preventing the endoscope body from excessive bending and folding, and reducing the maintenance rate of the endoscope.

[0016] 4. The utility model is provided with C-shaped limiting rings fixed on the inner side surfaces of the upper end, middle position and lower end of the sleeve body respectively. The opening of the limiting ring coincides with the notch.

Example 1

[0026] like Figure 1 、 Figure 2 As shown, a device for controlling and protecting the curvature of a digestive endoscope sheath comprises a sleeve 1 with upper and lower openings. The sleeve 1 is a conical structure with a larger upper portion and a smaller lower portion. A lateral notch 11 is provided on one side of the sleeve 1. The notch 11 passes through the sleeve 1 from top to bottom, and tensioning structures 2 are respectively provided at the upper and lower ends of the outer side of the notch 11.

[0027] The tensioning structure 2 includes a C-shaped fixing frame 21 embedded in the sleeve 1. Rectangular grooves 22 connecting to the fixing frame 21 are provided on the sleeve 1 on both sides of the notch 11. The fixing frame 21 in the left rectangular groove 22 is hinged to the left end of the pull plate 23 (an arc-shaped structure that cooperates with the outer surface of the sleeve 1) through a hinge shaft 24. A wedge-shaped first clamping block 25 is provided on the inner side of the right end of the pull plate 23, and a second clamping block 26 that hooks and pulls with the first clamping block 25 is fixed on the fixing frame 21 in the right rectangular groove 22.

[0028] A handle 231 (a raised rectangular parallelepiped) is fixedly provided on the outer side of the right end of the pull plate 23 to increase friction and facilitate pulling the pull plate 23 to the right.

[0029] During use, the sleeve 1 can be placed on the outside of the sheath tube near the handle through the notch 11. The tensioning structure 2 tightens the sleeve 1 and prevents it from slipping out of the notch 11. The sleeve 1 can increase the overall strength of the sheath tube, increase its bending resistance, and provide protection for the sheath tube. After the sleeve 1 is placed on the sheath tube, the pull plate 23 can be rotated via the hinge shaft 24. Then, the right end of the pull plate 23 is pulled to lock the first and second clamping blocks 25 and 26, thereby tightening and preventing it from slipping out. Example 2

Example 3

[0032] like Figure 4 As shown, C-shaped limiting rings 4 are fixedly provided on the inner side surfaces of the upper end, the middle position and the lower end of the sleeve body 1, and the opening of the limiting ring 4 coincides with the notch.

[0033] The vertical cross section of the limiting ring 4 is a circular structure.

[0034] During use, when the tensioning structure 2 is tightened, the limiting ring 4 can be pressed against the outer surface of the sheath tube, thereby reinforcing the limiting effect on the sheath tube and preventing it from slipping. Example 4

[0035] like Figure 5 As shown, vertically spaced annular grooves 12 are provided between the upper and lower tensioning structures 2 on the outer surface of the sleeve body 1 .

[0036] When in use, the annular groove 12 is convenient for workers to grasp and plays an anti-slip role.
