In the present embodiment, the main body portion is laser-machined using aluminum. Alternatively, copper, brass, tungsten or alloys thereof may be used, provided that the material selected must have a thermal diffusivity greater than or equal to 3.0 x 10 -5 m 2 And s. Of course, the main body may be made of plastic material, but the design of the circuit needs to be added to the conductive portion, and in view of heat conduction, in order to quickly diffuse and prevent the heat from the tip from concentrating, it is still preferred to make the main body made of metal material with electrical conductivity and high heat diffusivity. The preferred aluminum body has the additional advantages of light weight and reduced burden on the surgeon; compatibility of MRI, avoiding the risk of examination; sufficient rigidity and strength and no toxicity; so that the method has unique advantage in selection.
In this embodiment, the portion of the tissue contacting portion that does not contact tissue when the bipolar forceps are in use is covered with an insulating layer.
In this way, the resistance to thermal diffusion is reduced, provided that it is possible to prevent electrical leakage from damaging healthy tissues of the patient.
In one embodiment, the portion of the tissue contacting portion not provided with the patch is covered with an insulating layer.
In this way, the resistance to thermal diffusion is reduced, provided that it is possible to prevent electrical leakage from damaging the healthy tissues of the patient.
In this embodiment, the body portion is integrally formed with the tissue contacting portion. For example, laser cutting may be used to cut the metal into its final shape, or stamping, water jet cutting, EDM, plasma cutting, or molding may be used to form the body portion and tissue contacting portion.
The invention also provides a bipolar coagulation device, which comprises the bipolar coagulation forceps and power supply equipment, wherein the power supply equipment comprises a power supply end 5, and the power supply end 5 is used for supplying power to the bipolar coagulation forceps.
The invention also provides a manufacturing method of the bipolar coagulation forceps, which is used for manufacturing the bipolar coagulation forceps, and the manufacturing method of the bipolar coagulation forceps comprises the following steps:
manufacturing a main body part and a tissue contact part connected with the main body part;
the patch 3 is attached to a partial area of the tissue contact part in an attaching mode, the partial area at least comprises a part of the tissue contact part 2, which is contacted with the tissue, and the patch is used for assisting the tissue contact part in heat dissipation when the bipolar coagulation forceps work.
The main body part and the tissue contact part connected with the main body part are manufactured in an integrated forming mode.
Specifically, the integrated molding mode is as follows: one of die-cut, water-jet cutting, EDM, plasma cutting, or molding.
In this embodiment, the main body portion is coated with an insulating layer and the tissue contact portion is coated with an insulating layer at a position where the patch is not attached.
The working mode of the bipolar electric coagulation forceps is carried out in a bipolar mode, the output power is small, the action range is limited between two tips of the forceps, high-frequency electric energy is supplied to tissues by the two tips, vascular tissues at two ends of the electrode forceps are dehydrated and coagulated to achieve the aim of stopping bleeding, and the damage degree and the influence of the action range on the tissues are far lower than those of a single electrode mode, so that the electric coagulation forceps are also suitable for fine surgical operations, such as cranial nerve surgery, ophthalmology, ear-nose-throat department and the like.
The invention provides a hemostatic aid which is high in safety and reliable in hemostasis during a surgical operation, and avoids secondary injury and bleeding caused by adhesion of hemostatic materials and patient tissues.
Finally, it should be pointed out that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
