Abstract

The invention relates to the technical field of medical instruments, in particular relates to a medical surgical grabbing nipper. The surgical grabbing nipper comprises two pieces of clamps which are relatively arranged in upper position and lower positions, clamping force can be shifted by the clamps following the size differences of the clamped object, so as to ensure that forces are received evenly by the clamped object. The medical surgical grabbing nipper has the beneficial effects that a push pipe is moved forward under the external force relative to a connection rod and the grabbing nipper arranged on the front end of the connection rod is made to be gradually closed, after the external force vanishes, the push pipe is returned to its original position, and the grabbing nipper on the front end of the connection rod under the action of the elastic force of an elastic component itself gradually opens. The medical surgical grabbing nipper is simple in structure overall, easy to operate, lower in product processing difficulty, and easy to clean and disinfect, by the multi-connection combination mode of the grabbing nipper clamps with the connection rod, the production costs are decreased and different types of grabbing nippers can be replaced, and the service life overall is lengthened, the clamps have super elastic properties, in the grabbing process it is guaranteed that even forces are received by the tissues, the operational risk is subdued and the medical surgical grabbing nipper is good in practicality.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical surgical grasping forceps. Background technique [0002] Tissue grasping forceps are one of the commonly used instruments in surgical operations. At present, the grasping forceps are made of stainless steel multi-piece structure, combined through a four-link hinge mechanism. One end of the four-link hinge mechanism is connected to the grasping forceps, and the other end is connected to the handle through wire traction. , the handle pulls or loosens the steel wire, thereby controlling the opening and closing of the grasping forceps, and realizing the functions of clamping, separating and hemostasis on tissues. Due to the fine structure of the four-link hinge, not only the manufacturing process is more complicated, which increases the production cost, but also the gaps of the four-link hinge structure are difficult to clean and disinfect after use, which affec...
