Description

A multi-channel liquid, solid, gas intervening hose

technical field

The invention relates to the technical field of medical instruments, in particular to a multi-channel liquid, solid and gas intervening hose.

Background technique

Many operations in the biomedical field require the use of small tubing to intervene in biological lumens (such as large blood vessels, urethra, vagina, upper gastrointestinal tract, duodenum/hepatobiliary pancreas, rectum/anus, etc.). The current operation plan is often to insert one/multiple hollow hoses (cannulas) as guide tubes, and pass other components (detection probes, implants, injection devices, etc.) through the cannula to reach the target site; or insert a Use a hollow hose for liquid operations such as lavage, diversion, and pressure measurement. However, with the rapid development of modern medicine in the direction of low-invasiveness, more and more interventional operations have replaced large incision operations, and interventional operations have become more complicated. A pipeline that can transport multiple liquids, solids or gases at the same time will bring more ideas and opportunities to medical operations.

Chinese patent document CN200420019618.4, 2005.02.09 discloses a multi-channel laparoscopic cannula, which includes a cannula body, a cannula retaining ring, and a cannula tail. On the body of the sleeve, there is a longitudinal through hole for installing the operating instrument in the body of the sleeve, the longitudinal through hole is the working channel, and the tail of the sleeve is connected to the outstretched part of the working channel. The above-mentioned working channels include a first main channel for inserting an observation mirror and a second main channel for inserting standard operating instruments.

Chinese patent document CN201320171552.X, published on 2013.11.06, discloses a multi-channel operation sleeve, including a puncture sleeve (1); a cavity (8) is provided in the puncture sleeve (1), and the The left end of the cavity (8) is provided with a surgical instrument operation port (9), and the right end of the cavity (8) is respectively provided with a ventilation tube jack (4), a laparoscopic jack (2) and a surgical instrument sleeve insertion port. hole (3); said ventilation tube jack (4) is provided with a ventilation tube (7), said laparoscopic jack (2) is provided with a laparoscopic sleeve (5), and said surgical instrument sleeve is inserted A surgical instrument sleeve (6) is arranged on the hole (3).

Chinese patent document CN201520015107.3, published on June 17, 2015, discloses a sleeve for in vivo microscopic imaging and synchronous recording of multi-channel electrical signals; the sleeve is a hollow porous cylinder with guides on it. tube; the inner diameter of the hollow part of the sleeve is 300-1000 microns; the guide tube is arranged on the outer periphery of the sleeve and distributed symmetrically in the center, and the hole diameter of the guide tube is 150 microns.

However, there are many types of interventional operations in medicine, and the above multi-channel sleeves are not universal, and the structural design shows that there is a large partition area between multiple channels, and the overall diameter of the lumen is large, which will lead to a larger diameter of the sleeve, which will further lead to The surgical incision is large, and the delivery of various liquids, solids, and gases must be carried out separately.

To sum up, there is an urgent need for an interventional device that can be applied to a variety of interventional procedures, has a lower space occupation, and can realize the simultaneous mixed transportation of multiple liquids, solids, or gases. However, there are no relevant reports so far.
