Abstract

The invention provides an auxiliary tool for assisting the installation of an implant of a heart chamber. The auxiliary tool is used for implanting a sewing ring assembly and comprises a left clamp and a right clamp, which are matched with each other in a clamping manner, the end parts of the left clamp and the right clamp are correspondently provided with a guide rail and / or guide groove for limiting the clamping position of the left clamp and the right clamp, and the left clamp and the right clamp are respectively provided with an arc which is matched with an arc of a lantern ring of a sewing ring in a positioning manner. The auxiliary tool is used for positioning the sewing ring when in heart operation, so that a doctor can cut the heart and installing an insertion blood pump through a single hand, the blood pump heart implanting process is simplified, and the surgical safety is improved; moreover, the auxiliary tool is simple in structure, convenient to operate, low in surgical difficulty and short in operation time.

Description

technical field [0001] The invention relates to an auxiliary tool for implanting a ventricular assist device into a body, and belongs to the technical field of blood pump implantation operations. Background technique [0002] A blood pump or a ventricular assist device is a small pump with variable speed and variable capacity that is used to completely replace the work of the heart. The ventricular assist device contains an inlet and an outlet. When implanted in the heart, the outlet is connected to the aorta through the artificial blood vessel, and the inlet is connected to the ventricle through the apex opening. The ventricular assist device is connected to the heart through the ventricular connection structure between the inlet and the outlet connected. [0003] During the blood pump implantation operation, the sewing ring assembly needs to be sutured to the myocardium with surgical thread. Currently, there are no special auxiliary tools for heart incision surgery, or re...
