[0001] The utility model relates to the field of electrocoagulation cutting, in particular to an electrocoagulation forceps and an electrocoagulation device. Background Art
[0002] The electrocoagulation device is a surgical instrument commonly used under endoscopy, mainly used for endoscopic polypectomy, biopsy sampling and vascular thermocoagulation. Traditional electrocoagulation devices, such as the electrocoagulation device disclosed in patent CN 103750901 A, are prone to accidentally burn other tissues during operation because the forceps head is mostly completely exposed. Although some electrocoagulation devices have an insulating cap at the head end of the forceps to reduce the exposure of the electrode, it also means that only a small area on the side can be used for cutting, and it is difficult for tissue to enter this area, making the cutting operation inconvenient. Utility Model Content

[0046] Example 1
[0047] An electrocoagulation device, such as Figure 1 As shown, it includes a handle, a tube assembly 2 extending from the handle, and an electrocoagulation forceps 1. The electrocoagulation forceps 1 is connected to the distal end of the tube assembly 2 and is controlled by the handle so that the electrocoagulation forceps 1 can be opened or closed.
[0048] Specifically, Figure 2 , 4 As shown in FIG. 5 , the electrocoagulation forceps 1 includes a first forceps member and a second forceps member that are rotatably connected via a first rotating shaft 15. By rotating the first forceps member and the second forceps member relative to each other, a closed state (in which the distal ends of the first forceps member and the second forceps member are close to each other) can be achieved. Figure 4 and Figure 5 as shown) or in an open state with the distal ends moving away from each other ( Figure 2 shown).
[0049] More specifically, Figures 9 to 11 As shown, the first forceps member includes a first forceps member main body 11 and a blocking portion 12. The bottom of the first forceps member main body 11 has a first conductive area 114 that can conduct electrical energy. Preferably, the first conductive area 114 protrudes from the bottom surface of the first forceps member main body 11 and is located in the middle area of the first forceps member main body 11. The extension direction of the first conductive area 114 is consistent with the first forceps member main body 11. The peripheral area of the first forceps member main body 11 except the first conductive area 114 is an insulating area. The blocking portion 12 is located at the distal end of the first forceps member main body 11, and the blocking portion 12 extends in a direction close to the second forceps member and protrudes from the first forceps member main body 11. The periphery of the blocking portion 12 is insulated, and the blocking portion 12 forms an accommodation space with the first forceps member main body 11. The provision of the insulating portion makes the periphery of the first forceps member main body 11 non-conductive, thereby avoiding accidental burns to other tissues due to improper operation.
[0050] like Figures 6 to 8As shown, the second forceps member includes a second forceps member main body 13 and a second conductive area 14 capable of conducting electrical energy. The upper part of the second forceps member main body 13 has a third conductive area 134 that is arranged opposite to the first conductive area 114 and can conduct electrical energy. Preferably, the third conductive area 134 protrudes from the upper surface of the second forceps member main body 13 and is located in the middle area of the second forceps member main body 13. The extension direction of the third conductive area 134 is consistent with the second forceps member main body 13. The peripheral area of the second forceps member main body 13 except the third conductive area 134 is an insulating area. When the electrocoagulation forceps 1 is in a closed state, the second forceps member main body 13 and the second conductive area 14 are located in the accommodating space. When the electrocoagulation forceps 1 is in a closed state, due to the blocking of the blocking part 12, the second conductive area 14 located at the distal end will not contact the tissue, so that the tissue will not be accidentally burned. When marking, cutting or electrocoagulation is required, the electrocoagulation forceps 1 is opened to expose the second conductive area 14, which is safer.
[0051] The second conductive area 14 is located at the distal end of the second forceps member main body 13, and the second conductive area 14 is spherical, preferably hemispherical. The hemispherical second conductive area 14 can help the operator to use the area to mark the lesion tissue first during surgery, and then clamp the lesion tissue, so that it can be accurately positioned, reduce thermal damage, and avoid medical accidents caused by cutting the range beyond expectations. At the same time, the operator can also use the area to open the lesion tissue or cut and electrocoagulate the tissue during use, which is easy to operate. Further, in order to facilitate the operator to open the lesion tissue, the width and height of the distal end of the second forceps member main body 13 are gradually reduced from near to far, and the maximum outer diameter of the second conductive area 14 is less than or equal to the minimum width and minimum height of the distal end of the second forceps member main body 13.
[0052] The conventional forceps member is straight, which makes it difficult to enter a narrow area. The inventor has made it easier to pass through a narrow area during surgery by bending the main part of the forceps member. Specifically, the distal ends of the first forceps member main part 11 and the second forceps member main part 13 are bent in the left and right direction y and the bending degrees of the two are the same.
[0053] More specifically, the main body 11 of the first tweezers member includes a first segment 111 of the first tweezers member, a second segment 112 of the first tweezers member, and a third segment 113 of the first tweezers member. The first segment 111 of the first tweezers member and the third segment 113 of the first tweezers member are straight segments, and the second segment 112 of the first tweezers member is an arc segment and is located between the first segment 111 of the first tweezers member and the third segment 113 of the first tweezers member. The setting of the arc of the arc segment can be based on actual needs, and this application does not make specific restrictions. The main body 13 of the second tweezers member includes a first segment 131 of the second tweezers member, a second segment 132 of the second tweezers member, and a third segment 133 of the second tweezers member. The first segment 131 of the second tweezers member and the third segment 133 of the second tweezers member are straight segments, and the second segment 132 of the second tweezers member is an arc segment and is located between the first segment 131 of the second tweezers member and the third segment 133 of the second tweezers member. The arc of the second segment 132 of the second tweezers member is equal to the arc of the second segment 112 of the first tweezers member.
[0054] The following is an exemplary discussion of preferred implementations of the handle and the tube assembly 2. The specific structures of the handle and the tube assembly 2 may also refer to the prior art.
[0055] See also Figures 1 to 3 The handle includes a handle body 3, a slider 4 slidably arranged on the handle body 3 along the axial direction of the handle body 3, and a cable 5 arranged in the tube assembly 2, one end of the cable 5 is connected to the slider 4, and the other end is connected to the first forceps member and the second forceps member through the first connecting rod 51 and the second connecting rod 52 respectively. Specifically, one end of the first connecting rod 51 is rotatably connected to the proximal end of the first forceps member through the second rotating shaft 53, and the other end is rotatably connected to the cable 5 through the 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 the third rotating shaft 54, and the other end is rotatably connected to the cable 5 through the fourth rotating shaft 55. When the operating slider 4 slides, the first connecting rod 51 and the second connecting rod 52 rotate under the drive of the cable 5 and drive the first electrocoagulation forceps 1 and the second electrocoagulation forceps 1 to rotate, so that the electrocoagulation forceps 1 are switched between the open state and the closed state. By adjusting the sliding distance of the slider 4, the adjustment of the opening angle can be achieved, and the present application does not make specific restrictions on the opening angle.
[0056] The cable 5 has a certain rigidity, and can push the first connecting rod 51 and the second connecting rod 52 under the drive of the slider 4, thereby driving the first forceps component and the second forceps component to rotate to open, or can pull the first connecting rod 51 and the second connecting rod 52 under the drive of the slider 4, thereby driving the first forceps component and the second forceps component to rotate to close. As a preferred example, the cable 5 can be a stainless steel wire.
[0057] The tube assembly 2 includes an outer tube 21 and a spring tube 22 disposed inside the outer tube 21 and coaxial with the outer tube 21. The distal end of the outer tube 21 is connected to the electrocoagulation forceps 1, and the proximal end is inserted into the handle body 3 and fixedly connected to the handle body 3. The handle body 3 has a conductive connector 31, which contacts the outer tube 21 and is used to energize the electrocoagulation forceps 1.
[0058] The above electrocoagulation device has at least the following advantages:
[0059] (1) The electrocoagulation device can provide two working modes. One is that during the operation, the operator can use the second conductive area 14 located at the distal end to first mark the lesion tissue, and then implement the clamping function to achieve the effect of cutting and coagulation. This can accurately locate and reduce thermal damage. The other is that it has a high-frequency cutting knife function, using the second conductive area 14 to produce instantaneous cauterization on the contacted tissue to achieve the effect of cutting and coagulation.
[0060] (2) Through the design of the insulation area, the energy is more concentrated, the cutting is faster, and the damage to the surrounding tissue is less. At the same time, improper operation can be prevented from accidentally burning other tissues, which improves safety.
[0061] (3) Different from the traditional straight electrocoagulation forceps 1, the electrocoagulation forceps 1 in the electrocoagulation device is a curved structure, which is more conducive to passing through narrow areas during surgery.
[0062] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
