Description

Multifunctional endoscope end cap

Technical Field

The utility model relates to a multifunctional endoscope tip cap, belonging to the technical field of auxiliary accessories of medical appliances.

Background

The front end cap is applied to the front end of the endoscope, and the front end cap has the effect of easily judging the diameter of the polyp with naked eyes at any time under the endoscope, so that a clinician can conveniently carry out subsequent operation, and the risk of colon cancer occurrence of a large colon polyp patient is possibly higher than that of a small polyp patient with the diameter of less than or equal to 5 mm. Thus, accurate assessment of polyp size is important for assessing cancer risk. However, standardized techniques for measuring polyp size in clinical practice remain to be established. Polyp study polyp size was assessed using an open biopsy forceps endoscope. In normal clinical practice, most endoscopists estimate the size of polyps only visually. Clinical enteroscopy polypectomy refers to adenomatous polyps that are more than 5 millimeters in diameter. Differences in methodologies for determining polyp size make it difficult to compare clinical study data for analysis and to determine indications for polypectomy.

The prior art cap only can clinically expand the field of view, but there is no standard for measuring the comparison of the size of clinical polyps, which results in substantially no direct determination of the size of the polyp during surgery.

Detailed Description

Example 1

As shown in figures 1 and 2, a multifunctional endoscope front end cap, a main body 1 adopts a transparent thin-wall tubular structure, the whole body is of a tubular structure with equal diameter, the lower end of the main body 1 is provided with scale marks 2 uniformly distributed on the circumference, the upper end of the main body is of a slope-shaped structure 3, wherein the wall thickness of the slope-shaped structure is gradually reduced from bottom to top, the multifunctional endoscope front end cap can be reversely installed on equipment, so that the multifunctional endoscope front end cap is convenient for stripping mucous membrane in special operations, for example, a tunnel is firstly established under the mucous membrane of esophagus in treatment through a POEM operation under the oral endoscopic esophageal sphincterotomy, the tunnel is opened to a place of the stomach through the tunnel, when the mucous membrane layer is opened after the tunnel is established, the auxiliary device is needed, thus the tunnel can be quickly entered, the front end cap with the slope-shaped structure can be used for replacing the device in reverse direction, the mucous membrane can be quickly stripped like a shovel, and the tunnel is successfully established.

As shown in fig. 3, the scale mark 2 is composed of a plurality of convex rhombuses 2-1, the length direction of the convex rhombuses 2-1 is parallel to the axis of the main body 1, and the circumference of the convex rhombuses 2-1 is uniformly distributed on the inner wall of the main body 1; the width of each convex diamond 2-1 is 0.1-mm-0.2 mm, and the interval between every two adjacent convex diamond 2-1 is 0.8-0.9 mm. For the convenience of processing and the clarity of identification, the scale mark 2 is a mark line floating on the outer surface of the main body, the mark line is printed by adopting other colors different from the main body, and can also be a natural color line or a laser engraving line, and the interval between every two adjacent mark lines is 0.9-1 mm.

In order to timely drain the waste liquid in front of the lens in operation, a liquid drain hole 4 is arranged on the outer circumference of the main body 1, and the liquid drain hole 4 is positioned above the scale mark 2.
