Description

Technical Field

[0001] This utility model relates to the field of cardiac stabilizer technology, specifically to a cardiac surgery stabilizer. Background Technology

[0002] The primary function of a cardiac stabilizer is to provide a stable surgical field, ensuring that surgeons can perform procedures such as vascular anastomosis precisely while the heart is beating. It typically stabilizes localized areas of the heart muscle by adhering to or pressing against the heart surface, reducing the amplitude of heartbeats. A cardiac stabilizer usually consists of multiple components, including but not limited to a handle, fixation brace, outer sheath, distal articulation, and stabilizing claws.

[0003] Existing cardiac stabilizers can adjust the overall suction pressure of the suction cups at the end. However, during surgery, the suction force of a single suction cup may be insufficient. It is difficult for medical staff to intuitively judge whether the cardiac stabilizer can maintain a stable suction state. Directly increasing the suction force may cause some suction cups to have excessive suction force, which is detrimental to the heart. In addition, the suction cups are generally fixed, and the surgical area between the suction cups is fixed, which is not convenient for adjustment and limits the application scenarios.

[0004] Therefore, the technology lacks a cardiac surgery stabilizer that allows for individual adjustment of the suction cup's adhesion force. Utility Model Content

[0054] Each suction cup 1 is connected to a negative pressure regulating component 3 via an independent suction tube 2, allowing the suction force of each suction cup 1 to be adjusted individually, ensuring flexible adjustments as needed during surgery. A regulating valve 31 is used to regulate the air pressure within the suction tube 2, while the controller electrically controls the opening and closing of the regulating valve 31, thereby achieving precise control of the suction force of each suction cup 1. Furthermore, medical personnel can monitor and adjust the pressure of each suction cup 1 in real time through the controller, ensuring that the suction force remains at its optimal level throughout the surgery, avoiding damage to the heart due to insufficient or excessive suction force.

[0055] In a preferred embodiment, the negative pressure regulating component 3 further includes a control tube 32.

The limiting hole 732 on the side of the stud 731 is designed to cooperate with the locking pin 61 to ensure the stability and positioning accuracy of the universal ball 73 during use. The locking pin 61 at a corresponding position on the side of the tripod 6 is designed so that after the universal ball 73 is installed, it can be fixed and positioned by inserting it into the limiting hole 732. When the locking pin 61 is inserted into the limiting hole 732, the universal ball 73 is effectively locked in a specific position, preventing it from moving accidentally due to external forces during surgery, thereby ensuring the safety and stability of the surgery. This design allows medical personnel to quickly insert or remove the locking pin 61 when adjusting the position of the universal ball 73, facilitating position adjustment and locking, and improving the convenience of operation. The cooperation of the limiting hole 732 and the locking pin 61 ensures that the universal ball 73 remains in the predetermined position during the operation, reducing the surgical risks that may be caused by equipment movement.
