A cutting device for aortic surgery

Abstract

The invention relates to the field of medical devices, and specifically discloses a cutting device for aortic surgery, comprising a main cylinder body and a positioning bracket. The positioning bracket includes a backing plate, in which a circular through hole for the coronary artery is opened, and the main cylinder is installed on the positioning bracket in a coaxial manner with the through hole. Can move in the axial direction of the via. The present invention facilitates the cutting of the vascular sheet at the coronary ostium to the desired shape and size within a short operation time, and makes it standardized and repeatable.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cutting device for aortic surgery. Background technique [0002] In the field of cardiovascular surgery, aortic root replacement is often performed for the treatment of aortic root aneurysms. The aortic root needs to be replaced with an artificial blood vessel, and the coronary artery originally opened at the aortic root needs to be replanted on the artificial blood vessel; The aortic wall at the coronary opening is cut off and trimmed into a round button shape, retaining the appropriate width of the edge (for example, 5.0mm), and then sutured to the artificial blood vessel; the round vascular piece can ensure that the suture is radial However, in the prior art, due to the lack of available instruments to complete the cutting and trimming of the vascular slices, the surgeon can only rely on manual trimming. (Cutting is a general term for cutting and trimming in this type of ...

[0002] In the field of cardiovascular surgery, aortic root replacement is often performed in the treatment of aortic root aneurysm, which requires artificial blood vessels to replace the aortic root, and the coronary arteries that originally opened at the aortic root need to be replanted on artificial blood vessels; The aortic wall at the opening of the coronary artery is cut off and trimmed into a circular button shape, with an appropriate width of the edge (for example, 5.0mm), and then sutured to the artificial blood vessel with sutures; the circular blood vessel piece can ensure that the sutures are radial , evenly arranged and not easy to bleed, is an important step for a successful operation and avoiding postoperative hemorrhage; however, in the prior art, due to the lack of available instruments to complete the cutting and trimming of the vascular slices, the operator can only rely on manual cutting (cutting is the general term for cutting and trimming in this type of surgery), this method is difficult to achieve standardization, and the cutting shape of vascular slices is often difficult to achieve the required shape and size (unsatisfactory shape, deviation in size, jagged edges, etc.) , which is more time-consuming and laborious for inexperienced operators, thus prolonging the operation time
