[0002] Bipolar electrocoagulation forceps is an important medical instrument, is widely used in surgical operation, especially in the operation needing hemostasis and tissue coagulation. Its head shape, structure, surface treatment determine the performance effect of bipolar electrocoagulation forceps in the working process. The technical background of bipolar electrocoagulation forceps can be traced back to its necessity for bleeding control in operation. In surgical operation, controlling bleeding is one of the key factors to ensure the success and safety of operation. Bipolar electrocoagulation forceps provides high-frequency electric energy, makes the tissue between bipolar forceps head electric coagulation, blood vessel dehydration coagulation, achieves the effect of body tissue hemostasis. This technology minimizes the risk of secondary damage caused by diffuse energy, has the advantages of good hemostatic effect, small secondary damage etc. The principle of bipolar electrocoagulation forceps is mainly through the current between two electrodes, makes tissue generate heat in the area between two electrodes, so as to achieve the purpose of hemostasis and tissue coagulation. This technology can effectively control bleeding, reduce the amount of blood loss in operation, improve the safety and efficiency of operation. However, the relative face of the head of traditional bipolar electrocoagulation forceps is usually a set of teeth mechanism, for example, a kind of bipolar electrocoagulation forceps disclosed in Chinese patent document CN215739400U, there are some limitations in actual use, for example: uneven stress, the gap between teeth may cause uneven stress, the fixed effect of tissue is not ideal; heat dispersion, tooth structure leads to heat dispersion, it is not easy to concentrate heat energy, which affects the coagulation effect, especially when high-efficiency hemostasis is needed, it is not good; uneven current distribution, the gap between teeth may cause uneven current distribution, which affects the overall effect of electrocoagulation; Large range of thermal damage, due to the difficulty in concentrating heat, it may cause a larger range of thermal damage, which has unnecessary influence on surrounding normal tissue; Large wound area, tooth structure may cause relatively large tissue wound area, which affects postoperative healing; Insufficient cutting performance, tooth structure is not sharp enough when cutting tissue, which causes uneven incision.

[0016] The utility model will be further explained in detail through the drawings and specific embodiments.

[0017] As shown in Figures 1-5 the utility model provides a kind of double-pole electrocoagulation forceps head structure with blade, including left tine 1, right tine 2 and pin shaft 3.

[0018] The left tine 1 includes left handle portion 11 and blade rod portion 12 on the distal end side of left handle portion 11, and blade edge 13 is provided on the blade rod portion 12.The right tine 2 includes right handle portion 21 and groove rod portion 22 on the distal end side of right handle portion 21, and blade groove 23 is provided on the groove rod portion 22 to cooperate with the blade edge 13.

[0019] The proximal end side of the left handle portion 11 and the right handle portion 21 is hingedly connected by pin shaft 3.In this embodiment, fixed mounting ear 14 is provided on the proximal end of the left handle portion 11.During electrocoagulation operation, the left handle portion 11 with blade edge 13 is stationary, and the right handle portion 21 performs opening and folding action.As the left handle portion 11 does not participate in rotation, the handle of the electrocoagulation forceps can be held to transmit force to the blade edge 13 on the left handle portion 11 for positioning cutting, which is beneficial to positioning cutting position.

[0020] The blade rod portion 12 and the left handle portion 11 form left step structure 110, i.e.the blade rod portion 12 protrudes from the left handle portion 11 towards the right tine 2.The groove rod portion 22 and the right handle portion 21 form right step structure 210, i.e.the groove rod portion 22 protrudes from the right handle portion 21 towards the left tine 1.When the left tine 1 and the right tine 2 are closed, the left handle portion 11 and the right handle portion 21 have gap 4, which can avoid clamping tissue to prevent the blade edge 13 and the blade groove 23 from closing during electrocoagulation operation, and also enables the clamping force formed by the left tine 1 and the right tine 2 to be concentrated on the blade rod portion 12 and the groove rod portion 22.

[0021] The blade edge 13 starts from one end of the blade rod portion 12 and extends to the other end of the blade rod portion 12 along the extension direction of the blade rod portion 12, and correspondingly, the blade groove 23 starts from one end of the groove rod portion 22 and extends to the other end of the groove rod portion 22 along the extension direction of the groove rod portion 22, so that the part held by the blade rod portion 12 and the groove rod portion 22 during the electrocoagulation operation can be located between the blade edge 13 and the blade groove 23, avoiding the situation that part of the tissue to be electrocoagulated may not be electrocoagulated.

[0022] In the embodiment, the cross section of the blade edge 13 is triangular. Correspondingly, the cross section of the blade groove 23 is also triangular. The tip of the triangular blade edge 13 is used to cut the tissue, and the side surfaces on both sides of the tip are used to compress the tissue.

[0023] The blade edge 13 includes a first portion 131 on the proximal end side and a second portion 132 on the distal end side, the blade of the first portion 131 and the blade of the second portion 132 have an inclined included angle, and the connecting portion of the first portion 131 and the second portion 132 protrudes toward the right jaw tip 2 side.

[0024] Obviously, the above-mentioned embodiments are only examples for clearly illustrating, and are not limitations to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
