Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The first embodiment,

Please refer to fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5. The utility model discloses a mediate laborsaving mistake proofing position electric coagulation forceps, include: the pair of tweezers comprises a front tweezers sheet 1, a tweezers handle 2 movably connected with one end of the front tweezers sheet 1, a tweezers sheet 3 and a tail connector 4, wherein the tweezers sheet 3 and the tweezers handle 2 are fixedly connected with the tail connector 4, the front tweezers sheet 1 is movably connected with the tweezers sheet 3 through a rotating shaft 5 penetrating through the front tweezers sheet 1 and the tweezers sheet 3, and the front tweezers sheet 1 can rotate relative to the tweezers sheet 3 by taking the rotating shaft 5 as a base point.

The non-stick material of the forceps tip part at the front ends of the front forceps sheet 1 and the forceps sheet 3 can be selected from silver-based alloy, copper-based alloy, gold-based alloy and the like. Compared with the common electric coagulation forceps on the market, the pair of forceps has the advantages that the labor-saving structure is formed by the front forceps piece 1, the forceps handle 2 and the forceps piece 3, the moment of kneading force is longer, labor is saved, the kneading force required by the pair of forceps is smaller when the same clamping force is applied to tissues, and the pair of forceps is helpful for relieving the fatigue of doctors in the operation. The specific principle is as shown in fig. 4 and 5, fig. 5 is a force-bearing structure schematic diagram of a common electric coagulation forceps on the market, when the common electric coagulation forceps are used, a medical worker generally applies force to the middle part of the forceps piece 3 close to the forceps tip through a thumb, and because the supporting shaft point is at the tail connecting head 4, the moment corresponding to the force applied by the thumb is smaller than the moment corresponding to the clamping force formed at the forceps tip, so that the clamping force applied by the forceps tip to the tissue is smaller than the kneading force applied by the thumb, and the thumb needs to apply a larger force to enable the clamping force to reach the effect expected by the medical worker, which is also a more strenuous reason, and when the medical worker performs an operation for a long time, the medical worker can make hand muscle hard and sore more strenuous, and influence the effect at the later stage of the operation. The stress of the forceps is as shown in figure 4, through the structural arrangement of the forceps, the fulcrum is changed from the tail connecting head 4 to the rotating shaft 5, and the position of the thumb applying force of the medical staff is the end of the forceps handle 2 far away from the tail connecting head 4, so that the moment corresponding to the pinching force applied by the thumb is larger than the moment corresponding to the clamping force formed by the forceps tips, and the clamping force applied to the tissue is larger than the pinching force of the thumb, so that the medical staff can apply the force and perform the operation more easily. It can be easily found from the above comparison that the kneading force required by the present device is much less than that of the conventional type of electric coagulation forceps, with the same clamping force applied by the forceps tips. Meanwhile, the rotating shaft 5 is arranged at the position close to the forceps tips, so that the stability of the electric coagulation forceps is better compared with that of common electric coagulation forceps on the market, and even if the kneading force during kneading deviates from the direction of the forceps body, the forceps tips at the front ends cannot be dislocated, so that the accuracy of the operation can be ensured.

It should also be noted that when the common type electric coagulation forceps are held in the hand, besides the thumb pressing one of the forceps pieces 3, the side joint of the forefinger also needs to apply force to the other forceps piece 3 to maintain the stability of the electric coagulation forceps. The device can be used by supporting the forceps sheet 3 with a palm and pressing the front end of the forceps handle 2 with a thumb like holding a television remote controller, but the device can be used by keeping the electric coagulation forceps better without concentrating the force applied at a certain point in the palm supporting the forceps sheet 3, and is more in line with the ergonomic design.
