[0002] The structure of the electrocoagulation forceps used in electrosurgery is mostly a mechanism in which two forceps needles are fixed to a tail joint. The structure is simple, but has the following defects: the forceps needles themselves are relatively hard, and a large pinching force is required for direct pinching. After long-term pinching during the surgical operation, the doctor's fingers will be sore and fatigued. Utility Model Content

[0003] The technical problem to be solved by the utility model is to study a labor-saving electrocoagulation forceps which only needs a smaller kneading force when kneading.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A labor-saving electrocoagulation tweezers comprises a first tweezer needle, a second tweezer needle, a connecting sleeve, a pin and a clip. The tails of the first tweezer needle and the second tweezer needle are fixedly connected by the connecting sleeve. The opening between the first tweezer needle and the second tweezer needle gradually increases from the tail of the connecting sleeve along the extension direction of the tweezer needles. The middle parts of the first tweezer needle and the second tweezer needle are relatively provided with perforations. The connecting column of the pin passes through two perforations in sequence from the bottom of the second tweezer needle and extends out of the first tweezer needle. The connecting column of the pin is provided with a pin hole, and the pin hole is a barb hole structure; the clip comprises a connecting part, a holding part and a protrusion. The holding part is arranged obliquely upward at one end of the connecting part, and a protrusion is fixedly connected to the lower end of the holding part close to the connecting part. A limiting groove is provided at one end of the connecting part away from the holding part, and a limiting column is arranged in the limiting groove. Under the action of the elastic force between the first tweezer needle and the second tweezer needle, the limiting column is pressed tightly in the pin hole.

[0006] The beneficial effects of the utility model are: Figure 2 As shown, the holding part is pressed downward, and the connecting part drives the pin to move upward, so that the protrusion presses against the outer surface of the first tweezers needle, and the holding part is continued to be pressed downward. Under the pressure of the protrusion, the first tweezers needle moves closer to the second tweezers needle until the tweezers tip of the first tweezers needle is clamped with the tweezers tip of the second tweezers needle, and the electrocoagulation tweezers are kneaded; the holding part is relaxed, and under the elastic force between the first tweezers needle and the second tweezers needle, the pin moves downward, so that the holding part returns to its initial state; through the cooperation between the first tweezers needle, the second tweezers needle, the pin and the clip, the force arm of the kneading force is increased, and compared with the traditional direct kneading method, the same kneading effect is achieved, and the kneading force required is smaller, more labor-saving, and the doctor's fingers can be effectively prevented from being sore and fatigued by kneading for a long time. At the same time, the pin connects the first tweezers needle and the second tweezers needle in series through perforation, which can prevent the first tweezers needle and the second tweezers needle from being misaligned when kneading, and prolong the service life of the electrocoagulation tweezers. When the electrocoagulation tweezers are not in use, they can also be rotated counterclockwise around the pin and the clip is turned over, and the clip is close to the first tweezers needle for storage, saving space.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, one end of the holding portion away from the connecting portion is an arc-shaped plate structure recessed toward the first tweezers needle.

[0009] Furthermore, it also includes a rubber sheet, and the rubber sheet is bonded inside the arc-shaped plate structure.

[0010] Furthermore, the bottom of the second tweezers needle close to the connecting sleeve is widened and frosted.

[0011] Furthermore, the first tweezer needle and the second tweezer needle are both made of high thermal conductivity alloy; the connecting sleeve, the pin and the clip are all made of stainless steel.

[0012] Furthermore, the tips of the first tweezer needle and the second tweezer needle are finely polished. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figures 1 to 4As shown, embodiment 1 of the utility model is a labor-saving electrocoagulation forceps, comprising a first forceps needle 1, a second forceps needle 2, a connecting sleeve 3, a pin 4 and a clip 5. The tails of the first forceps needle 1 and the second forceps needle 2 are fixedly connected by the connecting sleeve 3, and the opening between the first forceps needle 1 and the second forceps needle 2 gradually increases from the tail of the connecting sleeve 3 along the extension direction of the forceps needles. The middle parts of the first forceps needle 1 and the second forceps needle 2 are relatively provided with perforations 6, and the connecting column of the pin 4 sequentially passes through the two perforations 6 from the bottom of the second forceps needle 2 and protrudes out of the first forceps needle 1. The connecting column of the pin 4 A pin hole 41 is provided on the column, and the pin hole 41 is a barb hole structure; the clip 5 includes a connecting portion 51, a holding portion 52 and a protrusion 53, and the holding portion 52 is arranged at an angle upward at one end of the connecting portion 51, and the holding portion 52 is fixedly connected with the protrusion 53 at the lower end near the connecting portion 51, and a limiting groove 511 is provided at one end of the connecting portion 51 away from the holding portion 52, and a limiting column 512 is arranged in the limiting groove 511. Under the action of the elastic force between the first tweezers needle 1 and the first tweezers needle 1, the limiting column 512 is tightened in the pin hole 41.

[0021] like Figure 2 As shown, the gripping portion 52 is pressed downward, and the connecting portion 51 drives the pin 4 to move upward, so that the protrusion 53 presses against the outer surface of the first forceps needle 1, and the gripping portion 52 is continued to be pressed downward. Under the pressure of the protrusion 53, the first forceps needle 1 moves closer to the second forceps needle 2 until the tip of the first forceps needle 1 is clamped with the tip of the second forceps needle 2, and the electrocoagulation forceps are kneaded; the gripping portion 52 is relaxed, and under the elastic force between the first forceps needle 1 and the second forceps needle 2, the pin 4 moves downward, so that the gripping portion 52 returns to its initial state; through the cooperation between the first forceps needle 1, the second forceps needle 2, the pin 4 and the clip 5, the force arm of the kneading force is increased, and compared with the traditional direct kneading method, the same kneading effect is achieved, and the kneading force required is smaller, more labor-saving, and can effectively prevent the doctor's fingers from being sore and fatigued by long-term kneading. At the same time, the pin 4 connects the first forceps needle 1 and the second forceps needle 2 in series through the perforation 6, which can prevent the first forceps needle 1 and the second forceps needle 2 from being misaligned when kneading, and prolong the service life of the electrocoagulation forceps. When the electrocoagulation forceps are not in use, the pin 4 can be rotated counterclockwise to flip the clip 5, and the clip 5 can be placed close to the first forceps needle 1 to save space.
