Embodiment Construction

[0023] see figure 1 , figure 2 , the rectal balloon dilatation catheter of the present invention comprises a catheter 2, a Y-shaped joint 3 and a balloon 1, the balloon 1 is arranged at the head of the catheter 2, the catheter 2 passes through the balloon 1 to form a tip configuration at the end, and the balloon The two ends of 1 are welded on the outer tube wall of catheter 2 to form a closed structure. The catheter 1 is a two-lumen tube set structure, which is divided into an inner catheter 21 and an outer catheter 22. The inner catheter 21 and the outer catheter 22 are connected by a fusion head , the inner conduit 21 runs through the entire conduit 1 , and the outer conduit 22 is sealed at the top end of the conduit 1 .

[0024] In the aforementioned rectal balloon dilatation catheter, one end of the Y-shaped joint 3 is connected to the tail of the catheter 2, one end is a liquid injection port 32, and the other end is a gas injection port 31. The inner catheter 21 commu...

Abstract

The invention relates to a rectum balloon dilatation catheter which comprises a catheter, a Y-shaped joint and a balloon, wherein the balloon is arranged at the head part of the catheter; the catheter comprises an outer catheter and an inner catheter arranged in a sheathing structure; and one end of the Y-shaped joint is connected with the tail part of the catheter, one end is a liquid injection port and an air injection port. The inner catheter is communicated with the liquid injection port, the outer catheter is communicated with the air injection port, and the catheter wall at the head part of the outer catheter is provided with a small hole for communicating the inner cavity with the balloon. The rectum balloon dilatation catheter is mainly used for improving detection quality and developing a new detection method. The invention has wide application range in clinic and can obviously improve image quality.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon dilation catheter for rectal imaging examination. Background technique [0002] With the continuous improvement of modern living conditions and the improvement of medical standards, clinically, infectious lesions continue to decrease, while lesions such as rectal and colon tumors, anal fistula, and hemorrhoids continue to increase. In an aging society, the elderly's constipation and anal incontinence And other clinical problems continue to receive widespread clinical attention. Therefore, the proportion of rectal lesions in the daily work of anorectal department and general surgery is constantly increasing. [0003] Before any lesion is treated, a clear diagnosis is required, and the clinical conditions such as the size, number, scope, degree, edge shape, and relationship with surrounding tissues of the lesion must be correctly evaluated. Doctors must obtain accurate inf...
