Example 1

An electric coagulation device, as shown in figure 1, comprises a handle, a tube assembly 2 extending from the handle and electric coagulation forceps 1, wherein the electric coagulation forceps 1 are connected to the distal end of the tube assembly 2, and the electric coagulation forceps 1 can be opened or closed under the control of the handle.

Specifically, as shown in fig. 2, 4 and 5, the electric coagulation forceps 1 includes a first forceps member and a second forceps member rotatably connected by a first rotation shaft 15, and by rotating the first forceps member and the second forceps member relative to each other, a closed state (shown in fig. 4 and 5) in which distal ends of the first forceps member and the second forceps member are close to each other or an open state (shown in fig. 2) in which distal ends are far from each other can be achieved.

More specifically, as shown in fig. 9 to 11, the first forceps member includes a first forceps member main body portion 11 and a blocking portion 12. The bottom of the first forceps member body portion 11 has a first conductive region 114 capable of conducting electrical energy, and preferably the first conductive region 114 protrudes from the bottom surface of the first forceps member body portion 11 and is located in the middle region of the first forceps member body portion 11, and the extending direction of the first conductive region 114 coincides with the first forceps member body portion 11. The outer peripheral region of the first forceps member main body portion 11 excluding the first conductive region 114 is an insulating region.

The provision of the insulating portion renders the outer periphery of the first tweezer member body portion 11 non-conductive, thereby avoiding mishandling of burns of other tissue.

The upper portion of the second forceps member body portion 13 has a third conductive region 134 disposed opposite the first conductive region 114 and capable of conducting electrical energy, preferably, the third conductive region 134 protrudes from the upper surface of the second forceps member body portion 13 and is located in the middle region of the second forceps member body portion 13, and the third conductive region 134 extends in the same direction as the second forceps member body portion 13. The outer peripheral region of the second forceps member main body portion 13 excluding the third conductive region 134 is an insulating region. When the electric coagulation forceps 1 are in the closed state, the second forceps member main body portion 13 and the second conductive region 14 are located in the accommodating space. When the electric coagulation forceps 1 is in a closed state, the second conductive area 14 at the far end cannot be contacted with the tissue due to the blocking of the blocking part 12, so that the tissue cannot be burned by mistake, and when marking, cutting or electric coagulation is needed, the electric coagulation forceps 1 is opened to expose the second conductive area 14, so that the safety is better.

A second conductive region 14 is located distally of the second tweezer member body portion 13, the second conductive region 14 being in the shape of a spherical cap, preferably hemispherical. The hemispherical second conductive area 14 can help an operator to mark focal tissues firstly by using the area in operation and then clamp the focal tissues, so that the focal tissues can be accurately positioned, thermal damage is reduced, medical accidents caused by exceeding a cutting range can be avoided, and meanwhile, the focal tissues or cut and electrically coagulated tissues can be opened by using the area in the use process of the operator, so that the operation is convenient.

The traditional forceps member is straight, and is difficult to enter a narrow area, and the inventor is more beneficial to passing through the narrow area in operation through the bending arrangement of the main body part of the forceps member. Specifically, the distal ends of the first forceps member main body portion 11 and the second forceps member main body portion 13 are bent in the left-right direction y and the degree of bending is uniform.

More specifically, the first forceps member main body portion 11 includes a first forceps member first section 111, a first forceps member second section 112, and a first forceps member third section 113, the first forceps member first section 111 and the first forceps member third section 113 are straight sections, the first forceps member second section 112 is an arc section and is located between the first forceps member first section 111 and the first forceps member third section 113, and the arrangement of the arc section radian may be according to practical requirements, the present application is not limited in particular. The second forceps member body portion 13 includes a second forceps member first section 131, a second forceps member second section 132, and a second forceps member third section 133, the second forceps member first section 131 and the second forceps member third section 133 being straight sections, the second forceps member second section 132 being arcuate sections and being located between the second forceps member first section 131 and the second forceps member third section 133, the arc of the second forceps member second section 132 being equal to the arc of the first forceps member second section 112.

Specifically, one end of the first connecting rod 51 is rotatably connected to the proximal end of the first forceps member through a second rotating shaft 53, the other end is rotatably connected to the pulling rope 5 through a fourth rotating shaft 55, one end of the second connecting rod 52 is rotatably connected to the proximal end of the second forceps member through a third rotating shaft 54, and the other end is rotatably connected to the pulling rope 5 through a fourth rotating shaft 55. When the operation slide block 4 slides, the first connecting rod 51 and the second connecting rod 52 are driven by the inhaul cable 5 to rotate and drive the first electric coagulation forceps 1 and the second electric coagulation forceps 1 to rotate, so that the electric coagulation forceps 1 are switched between an open state and a closed state. The adjustment of the opening angle can be achieved by adjusting the sliding distance of the slider 4, and the present application is not particularly limited with respect to the opening angle.

The guy cable 5 has a certain rigidity, and can push the first connecting rod 51 and the second connecting rod 52 under the driving of the sliding block 4, so as to drive the first forceps member and the second forceps member to rotate to open, or can pull the first connecting rod 51 and the second connecting rod 52 under the driving of the sliding block 4, so as to drive the first forceps member and the second forceps member to rotate to close. As a preferred example, the cable 5 may be a stainless steel wire.
