Abstract

The invention belongs to the technical field of injector equipment, and discloses a myocardial protection perfusion device for cardiac surgery minimally invasive surgery, which comprises a needle head, a valve fixedly sleeves the upper end of the needle head, the lower space of the valve is communicated and connected with the internal space of the needle head, and the upper end of the valve is fixedly connected with a syringe. The lower space of the syringe is communicated with the upper space of the valve, the outer wall of the syringe is slidably sleeved with an elastic operating frame, a piston is slidably arranged on the inner wall of the syringe, the lower portion of the piston is in sealed contact with the inner wall of the syringe, and the upper end of the elastic operating frame is matched with the piston in a buckled mode. The syringe comprises a U-shaped fingerstall and a syringe body. By loosening the elastic operating frame to close the valve by means of elastic force, inserting the needle into the body of a patient, pressing the upper part of the elastic operating frame to open the valve, and pulling the piston by means of the elastic force of the elastic operating frame to perform injection, the injection speed is stabilized, so that the injection work is facilitated.

Description

technical field [0001] The invention belongs to the technical field of syringe equipment, in particular to a myocardial protection perfusion device for minimally invasive cardiac surgery. Background technique [0002] A syringe is a common medical device that uses a needle to draw or inject gas or liquid. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in this technology: after the conventional syringe inhales the target liquid, when performing the injection, it is necessary to manually press the injection, and the pressing speed needs to be controlled during the process, thereby causing the conventional injection. The injection process of the syringe is more troublesome. [0004] To this end, we propose a myocardial protection perfusion device for minimally invasive cardiac surgery to solve the above problems. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to provide...
