Description

Technical Field

[0001] The utility model relates to a bipolar electric tweezers, specifically a bipolar electric tweezers which is not easy to have dirt transfer during the operation, and the residual tweezers surface is flush with the tweezers blades. Through the above-mentioned flush and flat design, the step structure problem caused by the height difference is reduced, and the step structure is prevented from causing dirt or tissue residue and transfer during the operation, thereby better ensuring the smooth completion of the operation. Background Art

[0002] The rapid development of minimally invasive technology has led to a continuous growth in the market demand for bipolar electric forceps. Bipolar electric forceps is an active medical device that is easy to operate, has fast coagulation, and has good results. It is widely used in minimally invasive surgery. Unlike traditional scalpels, the basic principle of bipolar electric forceps is to denature the collagen and elastin of the tissue clamped between the electrodes through physical compression and heat energy transfer between the two polar forceps, so that the blood vessel wall fuses into a transparent band to achieve the purpose of permanently sealing the blood vessel. It is mostly used for separation and ligation of vascular-rich tissues such as the greater omentum and mesentery.

[0003] In the structure of the existing bipolar electric tweezers, Figure 1 There is a certain height difference between the tweezers tip and the tweezers blades as shown. There are two reasons for the above height difference. The step on one side is caused by the insulation of the tweezers blades, and the insulating paint layer and the insulating glue layer are added. The step on the other side is a design necessity. The reason is to make the tweezers tip contact and cooperate earlier than the tweezers body, thereby realizing the function of the electric tweezers itself. In summary, the current tweezers tip actually has a step-like structure. The step-like structure does not affect the function and use of bipolar electric tweezers, but the existence of the step will cause another risk in the operation. Specifically, the step structure may get attached to the tissue. At the same time, the cut tissue or coagulated blood clots may be transferred through the step, which will have a certain impact on the operation. In severe cases, it will affect the life and health of the person undergoing the operation.

[0004] In addition, there are certain problems with the shape and structure of the tweezers tips in current bipolar electric tweezers. Specifically, the front end of current bipolar electric tweezers is in the shape of an arc-shaped sharp cone, which is too sharp and may cause accidental scratches.

[0005] In summary, the current two-stage electric tweezers need to be improved. Utility Model Content

[0006] The utility model aims to overcome the deficiencies in the prior art and provide a bipolar electric tweezers with tweezer tips flush with tweezer blades to better meet the use needs of precision surgery.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a bipolar electric tweezers with a tweezer tip flush with the tweezer blades, the tail ends of two symmetrical tweezer blades are fixed by an insulating fixing seat, the tail ends of the two tweezer blades are insulated and separated, and the tail ends of the two tweezer blades are connected to a conductive sheet inserted into the insulating fixing seat to achieve electrical conduction; an insulating layer is provided on the surface of the two tweezer blades; a tweezer tip is respectively arranged at the front end of the two tweezer blades, and a layer of titanium is plated on the surface of the tweezer tip to form a titanium layer, the top surface and two side surfaces of the tail of the tweezer tip are flush with the corresponding surfaces of the front end of the tweezer blades, and the bottom surface of the tweezer tip is flat and higher than the tweezer blades; the top surface and two side surfaces of the tweezer tip are linearly retracted from the tail to the head, so that the tweezer tip is conical.

[0008] Furthermore, there is an arc-shaped transition between the bottom surface of the tweezer tip and the tweezer blades.

[0009] Specifically, the front end surface of the forceps tip is a 60° inclined surface, and the corner of the front end is an arc-shaped transition surface formed by chamfering.

[0010] Furthermore, both side surfaces of the tweezer tip are inclined surfaces with an angle of 16 degrees, and the corners of the side surfaces are arc-shaped transition surfaces formed by chamfering.

[0011] Furthermore, the surface roughness of the outer surface of the tweezers tip is less than 0.5 μm.

[0012] Compared with the existing bipolar electric tweezers, the utility model has a uniform transition between the tweezer tip and the tweezer blade, which can effectively prevent the problem of tissue or dirt hanging due to the step structure, and improve the reliability of the use of the bipolar electric tweezers. At the same time, a new structure of the tweezer tip is designed, and each surface is an inclined surface with a curved surface transition, which reduces the sharpness of the top end and improves the safety of use.
