Problems solved by technology

[0002] At present, according to the requirements in the insulation of surgical accessories in GB9706.4 "Medical Electrical Equipment Part 2-2: Special Requirements for the Safety of High-Frequency Surgical Equipment", bipolar tweezers as accessories for high-frequency electrosurgical surgery need to withstand a withstand voltage of more than 1000V , so as to ensure that the bipolar tweezers are safe for patients and operators during use, so the insulation of the tweezers sheet is very important as a key component of the tweezers. For a long time, the insulation scheme of each bipolar tweezers is plastic spraying. A variety of materials, such as nylon, PTFE and other materials, are always incompatible in terms of effect and cost. A material with a lower cost is used, but the insulation effect is not ideal. In this part, the commonly used spray insulation material is used for insulation, which is often broken down; the other is to use high-cost materials, but as a one-time use product, this will undoubtedly increase the cost of the patient, not an economical choice

Embodiment 1

[0023] Such as figure 1 , 2 Shown, a kind of medical bipolar tweezers sheet, it comprises:

[0024] The body of the tweezers sheet is provided with a turning handle 11 on the body of the tweezers sheet;

[0025] Insulating shell 2, said insulating shell 2 is wrapped outside the turning handle 11, so that the insulating shell 2 isolates the contact between the operator and the conductive part of turning handle 11; in this embodiment, the conductive part of turning handle 11 The turning handpiece 11 made of metal material is covered with an insulating shell 2, which has the effect of effective insulation, and overcomes the unevenness of spraying on this part in the original spraying method (because there is metal in this part, there is a right-angled edge), which caused the impact. The phenomenon of wearing.

[0026] Such as figure 1 , 2 As shown, the tweezers sheet body also has a front part 12 and a rear part 13, and the front part 12, the turning handle part 11 and the r...

Embodiment 2

[0034] A medical bipolar tweezers comprises two symmetrically arranged medical bipolar tweezers pieces in Embodiment 1, and the two medical bipolar tweezers pieces are connected together in the shape of scissors.

Abstract

The invention discloses a medical bipolar tweezer piece and medical bipolar tweezers. The medical bipolar tweezer piece comprises a tweezer piece body and an insulating housing, wherein a handheld turning part is arranged on the tweezer piece body; the exterior of the handheld turning part is coated with the insulating housing, so that contact between an operator and a conductive part of the handheld turning part is conveniently isolated. According to the medical bipolar tweezer piece disclosed by the invention, a part needing to be insulated can be well insulated when the cost is not increased, and a phenomenon that an insulating layer of the original handheld turning part is easily broken down is avoided. Moreover, the condition that the original tweezer piece adopting a plastic sprayingmethod is instable in product quality due to air holes and burrs can be effectively overcome.
