Abstract
Description
Technical Field
[0001] This utility model relates to the field of plasma surgical scalpel technology, and in particular to a bipolar electrode with precision flow control. Background Technology
[0002] Existing bipolar electrodes, primarily bipolar forceps, do not offer specific guidance on flow control. They typically use roller-type regulating valves similar to those used for intravenous drips. However, these valves lack the precision required for precise flow regulation, failing to meet the micro-flow demands of bipolar forceps and resulting in poor performance. Specifically, excessive saline flow can generate condensation, obstructing the operator's view; insufficient flow can lead to dry burning, thermal damage, and tissue adhesion; and no flow makes it difficult to activate plasma for hemostasis and ablation.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a bipolar electrode with precision flow control, which facilitates precise control of the flow rate of physiological saline, avoids inconvenience caused by insufficient or excessive flow, and thus improves operational efficiency and surgical results.
[0005] The technical solution of this utility model is as follows: A bipolar electrode with precision flow control is provided, comprising: two cooperating positive and negative electrode assemblies, a fixing component, a power cord, a main suction tube, and a drip tube; the drip tube comprises: a first main drip tube, a second main drip tube, and a micro-flow regulator; the micro-flow regulator comprises: a connecting part, a rotating part cooperating with the connecting part, the rotating part rotating about the central axis of the connecting part; the connecting part is provided with an outlet, the rotating part is provided with an inlet, the first main drip tube is connected to the outlet, and the second main drip tube is connected to the inlet; the connecting part and the rotating part form a closed liquid cavity, the inlet and outlet are connected to the liquid cavity, and the cross-sectional area of the liquid cavity decreases sequentially from one end to the other; the fixing component fixes the two electrode assemblies, the power cord, the main suction tube, and the first main drip tube, and the power cord is electrically connected to the electrode bodies of the two electrode assemblies. The two working positive and negative electrode assemblies refer to two electrode components: a positive electrode assembly and a negative electrode assembly. These components work together, forming a circuit through physiological saline. The electrode assembly is the working part of the bipolar electrode, used for cutting and ablation. The fixing component secures the various parts, the power cord supplies power to the electrode body, and the main suction tube aspirates excess physiological saline during surgery. The first and second main drip tubes are channels for supplying physiological saline. The micro-flow regulator precisely adjusts the flow rate of physiological saline entering the first main drip tube from the second main drip tube, thereby achieving precise flow control and improving operational efficiency and surgical outcomes. Because the cross-sectional area of the liquid chamber decreases sequentially from one end to the other, it has the same adjustment function as a roller-type regulating valve, but this design achieves a quantitative effect (e.g., the flow rate decreases or increases by a certain amount for every 30° rotation), thus precisely controlling the flow rate of physiological saline and facilitating application.
[0006] Furthermore, in one embodiment, the connecting portion or the rotating portion is provided with an annular groove, the depth of which decreases sequentially from one end to the other, and the annular groove is disposed within the liquid cavity. In this embodiment, the cross-sectional area of the liquid cavity is gradually reduced by the sequential decrease in the depth of the annular groove from one end to the other, thereby adjusting the flow rate of physiological saline.
[0007] Furthermore, the micro-flow regulator also includes a sealing ring disposed in the liquid chamber, the sealing ring having a through hole that communicates with the liquid inlet and the liquid outlet.
[0008] Furthermore, the connecting portion is provided with a sealing groove, and the sealing ring is disposed within the sealing groove. The sealing groove facilitates the installation and positioning of the sealing ring.
[0009] Furthermore, the inlet is an inlet pipe and the outlet is an outlet pipe; the connecting part is provided with a rotating shaft, the rotating part is provided with a sleeve, the rotating shaft is inserted into the sleeve, and the sleeve and the rotating shaft are connected by a snap fastener.
[0010] Furthermore, a protective inlet sleeve is provided on the outside of the inlet pipe, and a protective outlet sleeve is provided on the outside of the outlet pipe. The protective inlet sleeve facilitates the connection between the second main dripping pipe and the inlet pipe, and the protective outlet sleeve facilitates the connection between the first main dripping pipe and the outlet pipe.
[0011] Furthermore, the outer side of the rotating part is a rotating cylinder, and the outer side of the connecting part is a force-bearing cylinder that cooperates with the rotating cylinder. The rotating cylinder facilitates the rotation of the rotating part.
[0012] Furthermore, the surface of the rotating drum is provided with several friction strips.
[0013] Furthermore, a reservoir is installed on the second main infusion tube. The reservoir is used to store physiological saline in the second main infusion tube.
[0014] Using the above-mentioned solution, this utility model provides a bipolar electrode with precision flow control, which employs a micro-flow regulator to precisely adjust the flow rate of physiological saline, thereby improving operational efficiency and surgical outcomes.

[0020] In this embodiment, the connecting portion 17 is provided with a sealing groove, and the sealing ring 20 is disposed within the sealing groove. The sealing groove facilitates the installation and positioning of the sealing ring.
[0021] In this embodiment, the liquid inlet is a liquid inlet pipe 22, and the liquid outlet is a liquid outlet pipe 23; the connecting part 17 is provided with a rotating shaft 24, and the rotating part 18 is provided with a sleeve 25. The rotating shaft 24 is inserted into the sleeve 25, and the sleeve 25 and the rotating shaft 24 are connected by a snap fastener.
[0022] In this embodiment, an inlet protective sleeve 26 is provided on the outside of the inlet pipe 22, and an outlet protective sleeve 27 is provided on the outside of the outlet pipe 23. The inlet protective sleeve 26 facilitates the connection between the second main dripping pipe 15 and the inlet pipe 22, and the outlet protective sleeve 27 facilitates the connection between the first main dripping pipe 14 and the outlet pipe 23.
[0023] In this embodiment, the outer side of the rotating part 18 is a rotating cylinder 28, and the outer side of the connecting part 17 is a force-receiving cylinder 29 that cooperates with the rotating cylinder 28. The rotating cylinder facilitates the rotation of the rotating part 18.
