[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example 1:

[0025] like Figure 1 As shown, this embodiment provides a monopolar device for endoscopic surgery, including a monopolar handle 1 and a monopolar head 2. One end of the monopolar handle 1 is connected to one end of the monopolar head 2 to form a monopolar device. The monopolar handle 1 is connected to a power source and retains the "cutting" and "coagulation" functions of the existing handle. The other end of the monopolar head 2 is provided with a metal tip 21. The metal tip 21 is a conical structure with a diameter that gradually decreases from one end near the monopolar handle 1 to the other end, and the length of the metal tip 21 is 5-10 mm to avoid accidental damage to other tissues. The diameter of the other end of the metal tip 21 is 1 mm, which facilitates precise operation in neurosurgery.

[0026] This invention features a metal tip 21 with a length of 5-10 mm at the head of the monopolar head 2. The appropriate length can prevent accidental damage to other tissues. The diameter of the other end of the metal tip 21 is 1 mm, meaning that the diameter of the head of the metal tip 21 is 1 mm. Its small size facilitates precise operation in neurosurgery and improves its practicality.

[0027] As a preferred embodiment of this invention, it should be further noted that one end of the monopole handle 1 is detachably connected to one end of the monopole head 2, which facilitates the replacement of the monopole head 2 according to actual conditions and improves practicality.

[0028] As a preferred embodiment of this invention, it should be further explained that one end of the single pole handle 1 is provided with a plug groove, and one end of the single pole head 2 is provided with a plug connector 23. The plug connector 23 is inserted into the plug groove, making the installation and removal method simple and practical. The middle part of the single pole head 2 is a connecting rod part 22 that connects the metal tip 21 and the plug connector 23, ensuring the length of the single pole head 2.

[0029] As a preferred embodiment of this invention, it should be further explained that the diameter of the connecting rod portion 22 is smaller than the diameter of one end of the metal tip 21. The connecting rod portion 22 is wrapped with a layer of wear-resistant, high-temperature resistant, and sterilizable insulating material, allowing for repeated sterilization. The material of the insulating material layer and the fact that the diameter of the connecting rod portion 22 is smaller than the diameter of one end of the metal tip 21 both make the insulating material layer more wear-resistant, preventing burrs after wear so that it can be reused without damaging normal brain tissue.

[0030] As a preferred embodiment of this invention, it should be further noted that the insulating material is a silicone resin layer, which can meet the usage requirements.

[0031] As a preferred embodiment of this invention, it should be further noted that the connecting rod 22 is a rod-shaped structure extending in a straight line, which is simple and practical.

[0032] As a preferred embodiment of this invention, it should be further noted that the single-pole handle 1 is a flat structure with a thickness less than its width and length. The flat design is beneficial for the surgeon's operation and increases the surgeon's operating space, preventing surgical instruments from interfering with each other.

[0033] Example 2:

[0034] This embodiment is a further improvement based on Embodiment 1. The specific differences between this embodiment and Embodiment 1 are as follows:

[0035] In this embodiment, the shape of the monopole head 2 can be varied and is not limited to the structural shape in Embodiment 1. This embodiment provides a new structural shape, such as... Figure 2 As shown, the connecting rod 22 includes a first connecting rod, a second connecting rod, and a third connecting rod connected sequentially from the metal tip 21 to the connector 23. The two ends of the second connecting rod are connected to one end of the first connecting rod and one end of the third connecting rod at a 100° angle. The other end of the first connecting rod extends away from the monopolar handle 1. The metal tip 21 and the monopolar handle 1 are not on the same straight line, forming a bend in the monopolar head 2. This design allows for deep cutting and hemostasis without obstructing the surgeon's view. It is suitable for situations with many endoscopic instruments, facilitates vertical operation, and prevents instruments from interfering with each other.

[0036] Example 2:

[0037] This embodiment is a further improvement based on Embodiment 1 or Embodiment 2. The specific differences between this embodiment and Embodiment 1 or Embodiment 2 are as follows:

[0038] In this embodiment, the shape of the monopole head 2 can be varied, and is not limited to the structural shape in Embodiment 1 or Embodiment 2. This embodiment provides a new structural shape, such as... Figure 3 As shown, the connecting rod 22 includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod, which are sequentially connected from the metal tip 21 to the connector 23. The two ends of the third connecting rod are connected to one end of the second connecting rod and one end of the fourth connecting rod at a 100° angle. The other end of the second connecting rod extends away from the monopole handle 1. One end of the first connecting rod is connected to the other end of the second connecting rod at a 100° angle. The other end of the first connecting rod extends away from the monopole handle 1 and the fourth connecting rod. This further increases the angle of the turning design, which can achieve hemostasis and tissue removal in blind areas that cannot be reached by a wider field of vision, resulting in better surgical outcomes.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
