Vascular transplantation equipment for cardiovascular surgery

Abstract

The invention relates to the technical field of medical instruments, and discloses vascular transplantation equipment for cardiovascular surgery. The equipment comprises two handle rods, cutter blocksare fixedly mounted at the bottoms of the two handle rods, a fixer is fixedly mounted at the junction of the two handle rods, a rotating disc is fixedly mounted on the front surface of the fixer, anda rotating disc is fixedly mounted on the back surface of the fixer. A miniature camera is movably clamped to the front face of the rotating disc, holding rings are fixedly mounted at the tops of thetwo handle rods, and rubber rings are fixedly mounted on the front faces of the interiors of the two holding rings. According to the vascular transplantation equipment for the cardiovascular surgery,the purposes of easy observation and good shearing effect are achieved by arranging the knife block, the handle rods, the miniature camera and the like, the included angle between the knife block andthe handle rod is 60 degrees, so that the situation of obviously obstructing the view during working is avoided, the knife block is of an obvious triangular structure, and the shearing effect is good; and meanwhile, the miniature camera is matched, so that the operation picture and the internal condition can be timely and effectively transmitted in real time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood vessel grafting device for cardiovascular surgery. Background technique [0002] Vascular grafting is a common surgical method when there is a defect in the blood vessel that cannot be sutured directly, including embedding the grafted blood vessel in the defect of the blood vessel, first suturing one end of the blood vessel to cut off the excess blood vessel, and then suturing the other end of the blood vessel. The grafted blood vessel can be an autologous artery , veins, or allogeneic arteries and veins, or artificial blood vessels, but in microvascular surgery, autologous arteries and veins are still the most commonly used. The vascular pedicle of the transplanted tissue is too short, and there is a defect between the vessel in the recipient area, and free blood vessels or vascular transposition cannot be used to overcome the defect; after debridement of the dam...

Problems solved by technology

[0003] The existing vascular transplantation equipment for cardiovascular surgery is the well-known surgical scissors. The scissors currently used still have certain problems for vascular transplantation. Concrete operation, therefore just need a kind of easy-to-use surgical scissors
