Description

Technical Field

[0001] The utility model relates to the technical field of surgical electrotomy electrodes, in particular to a surgical electrotomy electrode which is convenient for the rotation of a cutter head. Background Art

[0002] High-frequency electrode surgery is a purely physical treatment method. No drugs will be introduced into the tumor. The method is to use the current, heat energy and high-frequency electrocoagulation generated by the high-frequency electrode therapy device to act on the affected area under ultrasonic positioning, so that the diseased vascular tissue will gradually become organized and atrophied until it is completely closed and disappears. This treatment technology does not damage normal tissue cells and is non-destructive. It has a very wide range of applications. Disposable surgical electrodes are required in this process. This type of surgical electrode consists of a surgical handle (including a finger-press cutting switch and a finger-press electrocoagulation switch), a surgical cable, a surgical connector (plug), and a monopolar electrode (electric knife).

[0003] There are many types of such electrosurgical cutting electrodes on the market today, which can basically meet people's needs, but there are still certain shortcomings. During the use of such existing electrosurgical cutting electrodes, the staff needs to constantly rotate the direction of the electrode blade. Restricted by the shape of the electrode handle, it is inconvenient for the staff to rotate the blade after wearing medical gloves. It is difficult to rotate the blade flexibly, making it difficult for the electrode blade to accurately reach the lesion position, resulting in the lesion not being cleared, affecting the surgical effect.

[0004] In a Chinese patent with publication number CN 113813044 B, a medical surgical electrosurgical cutting electrode that is convenient for the rotation of the blade is disclosed, including an electrode handle body, a cutting switch, a coagulation switch and a cable body, a cutting switch is installed on one side of the surface of the electrode handle body, a coagulation switch is installed on one side of the surface of the electrode handle body, and the coagulation switch is arranged at intervals from the cutting switch, a cable body is installed at one end of the electrode handle body, and a surgical connector plug is installed at the end of the cable body, a first external thread groove is provided on one side of the surface of the electrode handle body, and a main limit ring is installed on one side of the surface of the first external thread groove. The present invention not only allows the staff to have better friction between the hand and the electrode, improves the staff's flexibility in operating the electrode, and enhances the working stability of the electrode, but also facilitates the rapid completion of the assembly of the electrode's accessory parts, and improves the convenience of using the surgical electrode.

[0005] However, the inventors found that the prior art, when in use, mainly rotates the secondary gear plate, which in turn drives the main gear plate and the electrode rod to rotate, thereby adjusting the working angle of the arc cutter head. Although this method is convenient for rotating the electrode rod, it is not convenient enough to accurately adjust the working angle in actual operation. Utility Model Content

A sliding ball 9 connected by a second spring 8 is installed inside the movable seat 18. The sliding ball 9 is slidably arranged in the sliding groove assembly. The first inclined groove 6, the middle horizontal groove 5 and the second inclined groove 7 form a stepped shape as a whole. After the sliding ball 9 enters the middle horizontal groove 5 from the first inclined groove 6, due to the different depths of the connecting positions of the first inclined groove 6 and the middle horizontal groove 5, the sliding ball 9 can be restricted from returning to the original position. Similarly, when entering the second inclined groove 7 from the middle horizontal groove 5, the entire rotating seat 4 is composed of a number of sliding groove assemblies connected in pairs. Specifically, the first inclined groove 6 in one sliding groove assembly is connected with the second inclined groove 7 in another sliding groove assembly (the surface of the connecting part is smooth, which is convenient for the sliding ball 9 to enter from one sliding groove assembly to another sliding groove assembly).
