Embodiment 1

[0024] see figure 1 and figure 2 and image 3 and Figure 4 , an embodiment provided by the present invention, a cannula with an elliptical section suitable for minimally invasive cardiac surgery, comprising a cannula main tube 1, a liquid storage tube 2 and an injection tube 3, and one end of the intubation main tube 1 is connected with a liquid storage tube 2. Intubation includes endotracheal intubation, inserting the tube into the human trachea through the pharynx and glottis for ventilation, gastric intubation, inserting the tube through the esophagus into the stomach of the human body to extract gastric juice or input nutrient solution, and the intubation supervisor 1 An injection tube 3 is arranged on the side, and a plurality of connecting pipes 4 are installed on one side of the surface of the liquid storage pipe 2, and a valve a5 is arranged on one side of the connecting pipe 4 surface, and a dosing pipe 6 is connected on one side of the connecting pipe 4 surface, ...

Embodiment 2

[0027] see figure 1 and figure 2 and image 3 , an embodiment provided by the present invention, a cannula with an elliptical section suitable for minimally invasive cardiac surgery, comprising a connecting rod 8, a sealing plug 7 and an injection tube 3, one side of the inner wall of the injection tube 3 is connected with a sealing plug 7, The appearance of syringe 3 is an epoch-making revolution in the field of medical appliances. The process of extracting and injecting gas or liquid with a needle is called injection. The injection tube 3 is composed of a syringe with a small hole at the front end and a matched piston core rod, which is used to inject a small amount of liquid or inject it into a place that cannot be used by other methods. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. A connecting rod is installed at the end of the seali...

Abstract

The invention discloses an elliptical section cannula suitable for minimally invasive cardiac surgery, which comprises a cannula main tube, a liquid storage tube and an injection tube, one end of the cannula main tube is connected with the liquid storage tube, one side of the cannula main tube is provided with the injection tube, one side of the surface of the liquid storage tube is provided with a plurality of connecting tubes, one side of the surface of each connecting tube is provided with a valve a, one side of the surface of the connecting tube is connected with a medicine adding tube, and the medicine adding tube is located at the top of the valve a. Through the arrangement of the cannula main tube, the liquid storage tube, the connecting tube, the valve a and the medicine adding tube, the effect of rapidly adding medicine into the device is achieved, operation of workers is facilitated, through the arrangement of the injection tube, a sealing plug, a connecting rod, a mounting tube and a valve b, the effect of effectively injecting the medicine or air by the device is achieved, and the device is convenient for workers to use.

Description

technical field [0001] The invention relates to the technical field of minimally invasive cardiac surgery, in particular to an oval-section cannula suitable for minimally invasive cardiac surgery. Background technique [0002] Minimally invasive cardiac surgery refers to cardiac surgery without extracorporeal circulation (that is, the heart does not stop beating) or through a small chest incision, which can reduce surgical trauma and surgical complications. With the development of thoracoscopic technology, robotic technology and closed extracorporeal circulation technology With the development, this type of surgery can be applied to coronary heart disease, valvular disease, congenital heart disease and other fields. [0003] A kind of elliptical cross-section cannula suitable for minimally invasive cardiac surgery in the prior art has disadvantages: [0004] 1. Patent document CN213312770U discloses a cannula with an elliptical section suitable for minimally invasive cardia...
