Problems solved by technology

However, there is a major problem with the above tools, that is, when operating, they are all operated directly by hand. There is inertia in the cutting process, the cutting scale is difficult to grasp, the accuracy is prone to deviation, and it is relatively easy to damage large blood vessels that do not need to be cut. security incident

Embodiment Construction

[0016] as attached figure 1 As shown, the fork-shaped radio frequency liver cutter includes a cutter head 1, a cutter bar 2, a rotary joint 3, a connecting wire 4, a main operation button 7, a water supply pipe 5 and a water flow adjustment button 8, a circuit board 9, a power pull rod 6, and a handle joint 10 and clamping handle 11. Cutter head 1 is connected with high-frequency power supply by connecting lead 4, main operation button 7, circuit board 9, during use, connects power supply by main operation button 7, controls and releases spectrum. After the cutter head 1 is inserted into the liver tissue, small blood vessels can be closed by using radio frequency heat generation. The cutter head 1 is also connected with the water supply pipe 5 with a diameter of 2 mm, and is controlled by the water flow adjustment button 8. When in use, the water flow adjustment button 8 is turned on, and the water flow flows into the operating field along the cutter head 1 through the water ...

Abstract

The forked RF liver exsector has one hollow trinacriform obtuse exsector head with side hole and made of conductive material, one main operating button, one circuit board and one HF power source connected together via connecting wires; one water pipe and one water flow regulating button communicated to the exsector head; one rotating joint set on the exsector bar and connected to the exsector head; and one clamping handle connected via one power pull rod and one handle joint on the exsector bar to the exsector head for controlling. During operation, the exsector head is first inserted into liver tissue to be exsected, and the clamping handle is then used to control the closing of the exsector head to exsect obtusely and cure liver tissue. The operation is accurate, fast and safe, and the forked RF liver exsector has compact structure, small size and easy operation.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a multifunctional fork type radio frequency liver cutting scalpel. Background technique [0002] Safety and speed are the two goals pursued in the process of liver resection. Safety mainly means that there is as little or no bleeding as possible during the liver cutting process, and no wrong or inaccurate cutting occurs; quickness means that the liver tissue can be separated quickly and the operation time is shortened as much as possible. Liver tissue is covered with a large number of reticular blood vessels and bile ducts. If instruments can be used to close the thin ducts and expose the thicker ducts without destroying them, the problem of liver resection will be easily solved. Surgical tools and methods used in the prior art mainly include: clamp method, high-frequency electric knife, ultrasonic knife and water knife. Although the clamp method can clamp the thicker pipeline, it can c...
