Description

Direct view minimally invasive grasping forceps

technical field

The utility model relates to a grasping forceps, in particular to a direct-viewing minimally invasive grasping forceps, which is suitable for minimally invasive human body surgery, and is specially used for grasping excised parts in the human body, and belongs to the field of medical equipment.

Background technique

In traditional surgical operations, an incision is usually made on the patient's skin and flesh, the short is 6-10 cm, and the length is 10-15 cm or longer. In the process of human body surgery, once a lesion is found in the human body, it needs to be removed. In the process of resection operation, the resected part needs to be taken out. The prior art is to use general forceps to grasp, and its defect is that the general forceps type is not firm in grasping. It is easy to fall off, which will bring trouble to the operation and cannot satisfy the ideal operation effect.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned problems existing in the prior art, and provide a direct-view minimally invasive grasping forceps with reasonable structural design and small trauma.

The technical solution adopted by the utility model to solve its technical problems is: the direct-viewing minimally invasive grasping forceps includes a fixed handle, a movable handle, a clamp rod, a pull rod, a flushing device, a fixed clamp, a movable clamp and a pull rod seat. The above-mentioned fixed jaws and movable jaws are provided with clamping teeth, and the clamping teeth are in a zigzag shape. It is characterized in that it is also provided with a pull rod groove and a support block. The pull rod groove is opened on the movable handle, and the pull rod seat is inserted into the pull rod groove to connect and fix. ; One end of the support block is fixed with the fixed handle by a fixing bolt, and the other end is connected and fixed with the pliers rod; the washer is fixed on the support block.

Compared with the prior art, the utility model has the beneficial effects that the structure design is reasonable, the grasping effect is good, and the operation is convenient and safe. Only need to incise 2-3 cm, use the special retractor to stretch the incision, and concentrate the light beam of the cold light source into the human body through the guide beam, which can not only make the surgeon clearly see all parts of the body directly, but also reduce the risk of injury due to the small incision risk of infection.
