Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a minimally invasive bipolar electrocoagulation knife. Background Art

[0002] During human surgery, it is sometimes necessary to use an electrocoagulation knife to stop bleeding. Commonly used electrocoagulation knives are divided into monopolar and bipolar. Monopolar electrocoagulation knives need to integrate a complete circuit in the blade, and the blade is thick and not suitable for use in delicate surgery. Bipolar electrocoagulation knives provide high-frequency electrical energy to body tissues through the two tips of bipolar forceps, causing the blood vessels between the two ends of the bipolar forceps to dehydrate and coagulate, achieving the purpose of hemostasis. Its range of action is limited to the two ends of the forceps, and the degree of damage and impact on body tissues is much smaller than that of monopolar methods.

[0003] The existing bipolar electrocoagulation knife only has the function of stopping bleeding, but not the function of cutting. During minimally invasive surgery using the bipolar electrocoagulation knife, if cutting is temporarily required, another surgical instrument needs to be replaced. Summary of the invention

[0004] The utility model aims at the drawback that the bipolar electrocoagulation knife in the prior art does not have a cutting function, and provides a minimally invasive bipolar electrocoagulation knife, which has not only a hemostatic function but also a cutting function.

[0005] The invention objective of the utility model is achieved through the following technical scheme: a minimally invasive bipolar electrocoagulation knife, comprising two blades forming a tweezer-like structure, the rear ends of the two blades are connected with an electric connector, the front end of the blade is an electrocoagulation head, the front end of the electrocoagulation head is a sharp structure, and a blade and a groove are provided on the inner side of each electrocoagulation head, the blade on any electrocoagulation head can be embedded in the groove on the other electrocoagulation head, a gap is left between the blade and the front end of the electrocoagulation head, and the two blades cooperate with each other.

[0006] Preferably, the plane where the two blade bodies are located is parallel to the blade.

[0007] Preferably, the blade is a triangular structure.

[0008] Preferably, a limit buckle is provided between the two blade bodies for limiting the opening between the two blade bodies.

[0009] Preferably, the limiting buckle is a U-shaped structure, and both ends of the opening of the limiting buckle are rotatably connected to one of the blades, and the other blade passes through the inner side of the limiting buckle.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the present invention, the interval between the blade and the front end of the electrocoagulation head can be used as a clamping position to clamp the wound when the minimally invasive bipolar electrocoagulation knife is used to stop bleeding. During the clamping process, the blade will be embedded in the corresponding groove, which will not affect the cooperation between the front ends of the two electrocoagulation heads;

[0012] 2. When the wound needs to be cut, two blade parts can be used for cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example

[0017] like Figure 1 , Figure 2 As shown, a minimally invasive bipolar electrocoagulation knife comprises two blade bodies 1 forming a forceps-like structure, the rear ends of the two blade bodies 1 are connected together with an electrical connector 2, the electrical connector 2 is provided with two electrode connectors 3, and the two electrode connectors 3 are electrically connected to the two blade bodies 1 respectively.

[0018] The front end of the blade body 1 is an electrocoagulation head 4, the front end of the electrocoagulation head 4 is a sharp structure, and a blade 5 and a groove 6 are provided on the inner side of each electrocoagulation head 4, the blade 5 is a triangular structure, the blade 5 on any electrocoagulation head 4 can be embedded in the groove 6 on the other electrocoagulation head 4, and there is a gap between the blade 5 and the front end of the electrocoagulation head 4, and the two blades 5 cooperate with each other to achieve the cutting function. The plane where the two blade bodies 1 are located is parallel to the blade 5.

[0019] A limit buckle 7 for limiting the opening between the two blade bodies 1 is provided between the two blade bodies 1 . The limit buckle 7 is a U-shaped structure. Both ends of the opening of the limit buckle 7 are rotatably connected to one of the blade bodies 1 , and the other blade body 1 passes through the inner side of the limit buckle 7 .

[0020] When using the utility model for hemostasis, the two blades 1 are connected to the positive and negative poles of the power supply through the two electrode connectors 3 on the electrical connector 2, and the two blades 1 are pressed to bring the two blades 1 closer together, driving the two electrocoagulation heads 4 to be applied to the part that needs hemostasis. At this time, the two electrocoagulation heads 4 act as two electrodes, and hemostasis is achieved under the action of electric energy. During this process, the blade 5 on the electrocoagulation head 4 will be embedded in the groove 6 on the other electrocoagulation head 4, so that the setting of the blade 5 will not affect the hemostasis function of the minimally invasive bipolar electrocoagulation knife. When the minimally invasive bipolar electrocoagulation knife needs to be used for cutting during minimally invasive surgery, it is only necessary to align the blade 5 with the part that needs to be cut, and the minimally invasive bipolar electrocoagulation knife can be used as scissors. The two blades 5 cooperate with each other for cutting, which is very convenient to use.
