Multi-cavity ureter support

Abstract

The invention discloses a multi-cavity ureter support. The multi-cavity ureter support comprises a first curling section (1), a straight pipe section (2) and a second curling section (3), the straight pipe section (2) includes a first straight pipe (4) and at least one second straight pipe (5), the first straight pipe (4), the first curling section (1) and the second curling section (3) compose a pipe, the second straight pipe (5) is located outside the first straight pipe (4), and the second straight pipe (5) and the first straight pipe (4) are two independent pipes. By means of the multi-cavity ureter support, building of a channel between a bladder and a renal pelvis can be achieved, ureter relevant diseases are treated, and the design of the unique shape helps a doctor to conveniently place and take out the support. By means of the multi-cavity design, the smoothness and safety of the support can be greatly improved, and the effect is more significant for a patient with the support inlay for a long time.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to the multi-lumen ureteral stent. Background technique [0002] Single lumen ureteral stent (e.g. figure 1 (Shown) has a history of more than 40 years of clinical use, and has a very obvious effect on the relief of ureteral obstruction. Stent tube alleviation is a complicated hydrodynamic process closely related to the nature of obstruction, ureteral peristalsis, and the nature and shape of the stent tube. A stent tube passing through the obstruction site does not guarantee adequate drainage. The long-term drainage failure rate can reach 16% to 53%. The main reasons for the failure may be that the stent tube is severely wrapped around the stent tube, the side hole is packed by the ureteral mucosa, and the tube cavity is blocked by necrotic tissue and blood clots. Summary of the invention [0003] In order to solve the problem of poor drainage effect of the existing single-lumen ureter...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of poor drainage effect of the existing single-lumen ureteral stent, the present invention provides a multi-lumen ureteral stent, which can not only increase the drainage in the cavity, but also reduce the external pressure distortion of the ureter and Compression increases the drainage of the stent lumen, effectively preventing the stent from being severely wrapped and adhering to human tissue
