Abstract

The invention discloses a neurovascular suturing assisting device. The neurovascular suturing assisting device comprises two transparent guiding catheters, clamping pliers and C-shaped pliers, whereinthe guiding catheters consist of a first curved pipe wall and a second curved pipe wall, first connecting ends of the first curved pipe wall and the second curved pipe wall are in rotary and fixed connection, and the other second connecting ends are in dismountable connection through a magnetic material; the guiding catheters are arranged at the tail end of a nerve blood vessel to be sutured in asleeving manner, and a first magnetic material is arranged at one ends being level with the sections of the tail ends, of the guiding catheters; a plurality of suture needle guiding holes penetratingthrough the catheter walls of the guiding catheters are formed in the guiding catheters, are close to the sections, and are radially and uniformly distributed; and a plurality of neurovascular end fixers are arranged on the catheter walls of the guiding catheters of the suture needle guiding holes and the sections, and are radially and uniformly distributed. According to the neurovascular suturing assisting device, the operation difficulty is greatly reduced, can assist doctors in standardized and acceptable completion of microsurgery repair, and can improve the suturing quality.

Description

Technical field [0001] The invention relates to the field of medical equipment, and in particular to a neurovascular suture auxiliary device. Background technique [0002] In the clinical and laboratory work of repair and reconstruction surgery and microsurgery, it is very difficult to suture and repair fine structures such as nerves and blood vessels, and it is difficult for doctors with relatively low qualifications to complete the repair with quality and quantity. Due to the uneven distribution of medical resources in my country, there is a shortage of medical staff and medical equipment in remote areas, which will make it more difficult to ensure that patients can receive proper microsurgical treatment. [0003] The patent CN 201911098010.2 provides a blood vessel suturing device. By setting a semicircular block, the two ends of the blood vessel are squeezed onto the inner wall of the notch through the squeezing block in the two semicircular blocks to complete the purpose of cl...
