Abstract

The invention relates to a supporting frame, in particular to a solenoid detachable channel sewing supporting frame, and belongs to the technical field of medical instruments. The supporting frame comprises an outer sleeve film and an elastic supporting ring arranged in the outer sleeve film, the elastic supporting ring can adhere the inner wall of the outer sleeve film, and a supporting body which can be embedded in a channel and support the channel is formed after the outer sleeve film is supported by the elastic supporting ring; guiding heads used for guiding the supporting body when the supporting body is embedded in a to-be-sewn channel are formed in two ends of the supporting body, a sewing groove used for sewing the channel is formed in the part between the guiding heads arranged attwo ends of the supporting body, a supporting flowing cavity is formed in the supporting body, and the supporting flowing cavity is communicated with liquid flowing ports formed in two ends of the supporting body. The supporting frame has a compact structure and can provide effective supporting for the sewing of the channel to improve the convenience of channel sewing, and the supporting frame issafe and reliable.

Description

technical field [0001] The invention relates to a support frame, in particular to a coil detachable lumen suture support frame, which belongs to the technical field of medical instruments. Background technique [0002] Currently, when arterioles are anastomosed, regardless of end-to-end anastomosis or end-to-side anastomosis, if the diameter of the arterioles is less than 2 mm, it is easy to suture the anterior and posterior walls of the arteries. It leads to postoperative suture complications such as arteriolar stenosis, thrombosis, and occlusion, resulting in poor surgical results and even surgical failure. [0003] There is an urgent clinical need for a surgical consumable that can stretch the vessel walls on both sides when suturing small arteries, providing surgeons with operating space for suturing, avoiding wrongly suturing the opposite side of the vessel wall during suturing, improving surgical efficiency, and improving surgical safety.
