Title:
DRAINAGE CATHETER, AND LAVAGE AND DRAINAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/092800
Kind Code:
A1
Abstract:
A drainage catheter and a lavage and drainage device, which relate to the field of medical instruments. The drainage catheter comprises a distal flexible tube (1), a proximal connecting tube (2), and a tube joint (3), wherein the distal flexible tube (1), the proximal connecting tube (2), and the tube joint (3) are each provided with a liquid-passing channel (100) and at least one steering wire channel (200); a proximal end of the distal flexible tube (1) is connected to a distal end of the proximal connecting tube (2) by means of the tube joint (3), a proximal end of the liquid-passing channel (100) of the distal flexible tube (1) is coupled to a distal end of the liquid-passing channel (100) of the tube joint (3), and a distal end of the liquid-passing channel (100) of the proximal connecting tube (2) is coupled to a proximal end of the liquid-passing channel (100) of the tube joint (3); proximal ends of the steering wire channels (200) of the distal flexible tube (1) are coupled to distal ends of the steering wire channels (200) of the tube joint (3) on a one-to-one basis; and distal ends of the steering wire channels (200) of the proximal connecting tube (2) are coupled to proximal ends of the steering wire channels (200) of the tube joint (3) on a one-to-one basis. The drainage catheter at least alleviates the problem of incomplete removal of hematoma fluid caused by a surgeon's inability to adjust the position of a suction port of a silicone tube in the existing lavage and drainage technology, and thus reduces the risk of having to operate again.
