AI Technical Summary
Existing surgical vascular clips are difficult to precisely grade the clamping force, which may lead to serious consequences such as excessively tight clamping that damages the vascular intima or excessively loose clamping that results in incomplete hemostasis or vascular clip dislodgement.
A surgical vascular clamp was designed, employing a micro-clamping mechanism. Initial clamping is achieved through the rotational structure of the right and left pressing handles. Combined with the sliding connection of the button and the locking groove, fine adjustment of the clamping force is realized. The cooperation of the transmission rod and the driven block enables fine adjustment of the anti-sliding block of the left clamp head, adapting to the needs of different blood vessels.
It achieves precise clamping of blood vessels, preventing clamps from being too loose or too tight, ensuring hemostasis, avoiding vascular clamp dislodgement, and improving the precision and safety of the surgery.
