Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to fig. 1, a high frequency scalpel negative electrode 100 according to an embodiment of the present invention is used as a negative electrode of an electrode scalpel, and includes a first insulating layer 10, a first conductive layer 30, and a second conductive layer 50. The first conductive layer 30 includes a conductive body 31 and a connecting portion 33, the conductive body 31 is disposed on the first insulating layer 10, and the periphery of the first insulating layer 10 extends out and covers the conductive body 31. The connecting portion 33 extends from the conductive body 31 to a direction away from the conductive body 31, and extends out of the first insulating layer 10 to connect to a negative electrode of an external power source. The second conductive layer 50 is disposed on a surface of the conductive body 31 away from the first insulating layer 10, covers the conductive body 31, and seals the conductive body 31 between the second conductive layer 50 and the first insulating layer 10, so as to reduce a current flowing through the second conductive layer 30 to a range that can be borne by a living body, such as a human body. The first conductive layer 30 has a conductivity greater than that of the first conductive layer 50.

The utility model discloses a high frequency scalpel negative pole 100's electrically conductive body 31 seals between second conducting layer 50 and first insulation layer 10, does not with human direct contact in the use, has improved the security greatly.

In some embodiments, the first insulating layer 10 is an insulating resin such as polypropylene (PP), Polyethylene terephthalate (PET), Polycarbonate (PC), Polyimide (PI), or a non-woven fabric.

Specifically, the first conductive layer 30 is a metal thin film, a composite metal thin film, a nano conductive thin film, or a multi-layer metal conductive thin film. More specifically, the first conductive layer 30 is a metal or an alloy of silver, copper, iron, aluminum, or the like having good conductivity. In some embodiments, the thickness of the first conductive layer 30 is 0.1mm to 1 mm. More specifically, the thickness of the first conductive layer 30 is 0.1mm, 0.2mm, 0.5mm, 0.8mm, 1.0mm, or the like. Therefore, the good conductivity of the high-frequency scalpel cathode 100 can be ensured, and the high-frequency scalpel cathode 100 cannot be too thick.

In some embodiments, the first insulating layer 10 and the first conductive layer 30 are bonded by an adhesive.

In some embodiments, the conductive body 31 and the connecting portion 33 may be integrally formed, which may simplify the manufacturing process. In other embodiments, the conductive body 31 and the connecting portion 33 are formed separately and then electrically connected by soldering or the like.

In some embodiments, the second conductive layer 50 is a conductive hydrogel layer. The thickness of the second conductive layer 50 is 0.1mm to 3 mm. More specifically, the thickness of the second conductive layer 50 is 0.1mm, 0.5mm, 1mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, or the like. When the thickness of the second conductive layer 50 is less than 0.1mm, the second conductive layer 50 is easily damaged or burrs thereof are generated, so that the organism is easily injured by electric shock during use, and the service life of the negative electrode 100 of the high-frequency scalpel is shortened. When the thickness of the second conductive layer 50 is more than 3mm, the cost of the high-frequency scalpel negative electrode 100 increases.

In some embodiments, second conductive layer 50 may be, but is not limited to, a polyhydroxyethylacrylate hydrogel, a polyacrylamide hydrogel, a chitosan-based hydrogel, a dopant or composite thereof, or a copolymer of these units, and the like.

Referring to fig. 2, in some embodiments, the second conductive layer 50 includes a first conductive hydrogel region 51 and a second conductive hydrogel region 53; the second electrically conductive hydrogel region 53 is disposed around the first electrically conductive hydrogel region 51; the second conductive hydrogel region 53 has a thickness greater than the thickness of the first conductive hydrogel region 51. This prevents the second conductive layer 50 from raising its edge, which may cause the first conductive layer 30 to directly contact the human body, which may result in electric shock.

Referring to fig. 3, in some embodiments, the high-frequency scalpel negative electrode 100 of the present invention further includes a second insulating layer 70; the second insulating layer 70 is annular and disposed around the second conductive layer 50, and a portion thereof covers the second conductive layer 50 and a portion thereof covers the first insulating layer 10. The second insulating layer 70 can better prevent the second conductive layer 50 from raising the edge, which causes the first conductive layer 30 to directly contact with the human body, resulting in electric shock.

In some embodiments, the second insulating layer 70 is an insulating resin such as polypropylene (PP), Polyethylene terephthalate (PET), Polycarbonate (PC), Polyimide (PI), or a non-woven fabric.

In some embodiments, the high-frequency scalpel negative electrode 100 of the present invention further includes a third insulating layer 20, the third insulating layer 20 is disposed on the second conductive layer 50, so as to facilitate the storage and transportation of the high-frequency scalpel negative electrode 100, and when in use, the third insulating layer 20 is removed, and the second conductive layer 50 is attached to the living body.

Referring to fig. 4, in some embodiments, the high-frequency scalpel negative electrode 100 of the present invention further includes an adhesive layer 80; the adhesive layer 80 is disposed at a portion where the first insulating layer 10 and the second insulating layer 70 are attached to each other, so as to increase the adhesive force between the first insulating layer 10 and the second insulating layer 70. The first insulating layer 10 and the second insulating layer 70 are prevented from falling off, and the service life of the high-frequency scalpel negative electrode 100 is prolonged.

Referring to fig. 5, the number of the first conductive layers 30 is two; two first conductive layers 30 are disposed on the first insulating layer 10 at intervals. The two first conductive layers 30 facilitate loop testing of the high frequency scalpel negative electrode 100.

Referring to fig. 6, the present invention further provides a surgical device 200, which includes an electrode knife 210, a negative electrode 100 of the high frequency surgical knife according to the embodiment of the present invention, and a power supply 230.
