Description

Technical Field

[0001] This utility model belongs to the field of surgical instrument technology, specifically relating to an aortic clamp for thoracoscopic surgery. Background Technology

[0002] Thoracoscopic cardiac surgery is a minimally invasive procedure that typically requires several small incisions in the chest. The procedure is performed using a thoracoscope and specialized surgical instruments. The thoracoscope is a long, thin instrument equipped with a camera that transmits images of the chest cavity to a monitor, allowing the surgeon to observe the images on the screen. This surgical method results in less trauma, faster recovery, less pain, and a relatively shorter hospital stay. During the procedure, clamps are usually used to close the aorta.

[0003] The utility model patent CN221383662U discloses an aortic clamping clamp for cardiac surgery, comprising a first clamping arm and a second clamping arm, hinges at the front ends of the first and second clamping arms, handles connected to the rear ends of the first and second clamping arms, clamp jaws connected to the front ends of both the first and second clamping arms, and a pouch connected to the front end of the clamp jaws, with a water inlet on the pouch. This design avoids complications such as plaque dislodgement that occur when using existing aortic clamping clamps.

[0004] However, when the above-mentioned method is used to clamp and block the aorta, the left atrial appendage is attached to the aorta, and the clamp cannot block the left atrial appendage, which can easily lead to bleeding in the left atrial appendage. Therefore, we propose an aortic clamp for thoracoscopic surgery. Utility Model Content
