Description

Direct vision minimally invasive large grasping forceps

technical field

The utility model relates to a forceps, in particular to a direct-viewing minimally invasive large-scale grasping forceps, which is specially used for grasping necrotic or diseased tissue in the abdominal cavity of a human body, and ensuring that the tissue will not fall off after being grasped. It belongs to the technical field of medical equipment.

Background technique

In direct-view minimally invasive laparoscopic human surgery, it is necessary to grasp the necrotic or diseased tissues and organs in the human abdominal cavity to ensure that they will not detach and fall off, so that the operation can proceed smoothly. The existing technology is to use ordinary grasping forceps for grasping. The defect is that the ordinary grasping forceps grasps by the teeth of the forceps. Because the teeth are short, the tissues and organs will be detached and fall off when pulled, which cannot be effectively grasped and cannot meet the ideal. effect of surgery.

Utility model content

The technical problem to be solved by the utility model is to overcome the above-mentioned deficiencies in the prior art, and provide a direct-viewing minimally invasive large-scale grasping forceps with reasonable structure design and convenient grasping.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the direct-view minimally invasive large-scale grasping pliers includes a fixed handle, a movable handle, a support block, a clamp rod, a pull rod, a fixed clamp, a movable clamp, a pull rod seat, and a return spring , shrapnel and rack, characterized in that: the fixed jaws and the movable jaws are both hook-shaped, and are provided with upper and lower matching teeth; a flushing part is also provided, and the flushing part is fixed on the described on the support block.

Compared with the prior art, the utility model has the following obvious effects: the structure design is reasonable, the design of the hook-shaped clamp and the upper and lower jaws are engaged, and the necrotic or diseased tissues and organs are effectively grasped to ensure that no It will detach and fall off, and the operation is convenient and safe.
