Document Type and Number:
WIPO Patent Application WO/2020/082362
Kind Code:
A1
Abstract:
Disclosed are a blood vessel clamping device. An upper jaw and a lower jaw are pivotally connected to the upper and lower sides of a front end of a rail, respectively; back ends of the upper jaw and the lower jaw at one side are crossed with each other, and the back ends at the other side are spaced apart vertically and are supported by a pre-clamp spring; a plurality of plastic nails is provided on the rail; a nail feeding push rod for pushing the plastic nails is provided; a pre-clamp push rod which is hooked with the nail feeding push rod is provided; the pre-clamp push rod is provided with a convex block; the convex block pushes the back ends of the upper and lower jaws which are crossed with each other to open the upper and lower jaws. In the present invention, when used, the blood vessel clamping device is mounted on an actuator, such as a drive handle, and when the nail feeding push rod pushes the plastic nails, the pre-clamp push rod can be firstly driven to advance, so that the convex block releases the upper and lower jaws to enter a pre-clamped state, the jaw structure can easily extend into a human body for a clamp operation, and the plastic nails can smoothly enter positions between the upper and lower jaws.
