The application discloses a kind of thoracic cardiovascular surgery vessel holders, belong to blood vessel clamping technical field, by support base component, multi-axis support component and clamping component composition, support base component uses double vacuum pump to be matched with double structure adsorption head, can be closely adsorbed in medical plane, provide stable base;Multi-axis support component includes seven-axis linkage structure and self-locking joint, can realize all-around angle and height adjustment, the sixth rotating shaft is telescopic rod, and depth fine adjustment can be completed in cooperation with assembly seat, and automatically lock position after adjustment;Clamping component is clamped by screw rod screw thread transmission and lever structure, and is matched with elastic clamp pad and gyro wheel, and clamping force is accurately controllable, and screw thread self-locking can be durable pressure retention;The device does not need to be continuously hand-held, can avoid blood vessel injury, adapts multiple blood vessel operation scene, effectively improves the safety and operating efficiency of thoracic cardiovascular surgery.

The present application belongs to the technical field of medical teaching instruments, and particularly relates to a surgical simulation device for thoracic surgery teaching, which comprises a mounting base, an adjusting portion arranged on the upper portion of the mounting base, and a simulation portion arranged in the adjusting portion. The adjusting portion can adjust the simulation portion to be inclined in the horizontal direction, and can also provide guidance and support during the removal of the simulation portion. The simulation portion comprises a docking seat, a shell, an organ bag and a gravity roller. The docking seat is fixedly connected with a sliding portion in the adjusting portion, the shell is fixedly connected with a rotating portion of the adjusting portion, and the gravity roller is arranged in the docking seat. The present application can simulate the gravity displacement of organs through the gravity roller, improve the authenticity of teaching, realize automatic posture switching through a movable groove, ensure stable removal, realize the integration of angle adjustment and removal guidance through an integrated adjusting portion, and has compact structure and convenient operation.

This utility model belongs to the field of medical device technology and discloses a tunneling knife for cardiothoracic surgery. It includes a knife body and blade tips and a handle respectively disposed at both ends of the knife body, with the blade tips being conical or bullet-shaped. This utility model has a simple structure, is easy to operate, can precisely control the size and shape of the incision, and results in a small surgical wound, making it highly practical. This utility model also includes a tunnel tube sleeved on the knife body. The tunnel tube sleeved on the knife body allows the tunnel tube to be inserted into the puncture tunnel during the puncture process. After the puncture is completed, there is no need to insert the tunnel tube separately after the puncture, which greatly improves surgical efficiency.
