DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a needle electrode that is easy to hold provided by the utility model; Figure 2 It is a schematic diagram of the exploded structure of the holding mechanism in the utility model; Figure 3 It is a structural schematic diagram of the first ring and the limiting groove in the utility model;

[0020] Figure 4 for Figure 3 A schematic diagram of the structure at A in the middle is enlarged. A needle electrode that is easy to hold, a needle 1, a handle 2 is arranged outside the needle 1, a holding mechanism 3 is arranged outside the handle 2, a connecting mechanism 4 is arranged on the holding mechanism 3, a wire 5 is arranged at one end of the needle 1, a connector 6 is arranged at one end of the wire 5, the holding mechanism 3 is used to facilitate medical staff to hold the handle 2, and the connecting mechanism 4 is used to disassemble and assemble the holding mechanism 3.

[0021] It should be noted that: by setting up the holding mechanism 3, it is convenient for medical staff to hold the handle 2, which is convenient for medical staff to perform clinical operations, and further convenient for medical staff to grasp the accuracy when inserting the needle. By setting up the connecting mechanism 4, it is convenient to fix the holding mechanism 3 on the handle 2, and it is also convenient to disassemble it, so that it is convenient for medical staff with different palm sizes to use.

[0022] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the holding mechanism 3 includes a first ring 31 and a second ring 32 arranged on the outside of the handle 2. The inner walls of the first ring 31 and the second ring 32 are both provided with a limiting groove 33. The limiting groove 33 is provided with an anti-slip sleeve 34. The anti-slip sleeve 34 is made of rubber and has a protrusion 35 on it.

[0023] It should be noted that: the first ring 31 and the second ring 32 are fixedly installed on the outside of the handle 2, and then the anti-slip sleeve 34 is moved to pass through the position of the needle 1, and is sleeved in the limiting groove 33 on the inner wall of the first ring 31 and the second ring 32. The first ring 31 and the second ring 32 make it convenient for medical staff to hold the handle 2. The anti-slip sleeve 34 and the convex point 35 can increase the friction between the palm of the medical staff and the first ring 31 and the second ring 32, thereby preventing the medical staff from slipping due to sweating on the palm.

[0024] refer to Figure 2 , Figure 3 and Figure 4 As shown, the connecting mechanism 4 includes a positioning block 41 fixed to the bottom of the first ring 31, an arc-shaped clamping block 42 is slidably connected inside the positioning block 41, a spring 43 is fixedly connected to one side of the arc-shaped clamping block 42, a positioning groove 44 is provided at the top of the second ring 32, and an arc-shaped clamping groove 45 is provided on the inner wall of the positioning groove 44.

[0025] There are four positioning blocks 41 , and each positioning block 41 is provided with two arc-shaped clamping blocks 42 .

[0026] It should be noted that: the first ring 31 and the second ring 32 are installed on the outside of the handle 2, and the positioning block 41 is inserted into the positioning groove 44. At this time, the arc-shaped block 42 in the positioning block 41 will contact the edge of the top of the positioning groove 44. The first ring 31 and the second ring 32 are continued to be moved closer to each other, and the positioning groove 44 will squeeze the arc-shaped block 42. The squeezing of the arc-shaped block 42 will compress the spring 43 and retract it into the positioning block 41. At this time, the positioning block 41 continues to move into the positioning groove 44. When the arc-shaped block 4 2 is level with the arc-shaped card slot 45, the arc-shaped card block 42 can be ejected from the positioning block 41 by the resilience of the spring 43, so that the arc-shaped card block 42 is stuck in the arc-shaped card slot 45, so that the first sleeve 31 and the second sleeve 32 can be fixed on the outside of the handle 2, which is convenient for medical staff to hold. When the first sleeve 31 and the second sleeve 32 need to be disassembled, the anti-slip sleeve 34 is first taken out, and then the first sleeve 31 and the second sleeve 32 are moved in opposite directions, so that the arc-shaped card block 42 can be separated from the arc-shaped card slot 45, which is convenient for disassembly and assembly.

[0027] The working principle of the needle electrode provided by the utility model that is easy to hold is as follows:

[0028] When in use, the first sleeve 31 and the second sleeve 32 are installed on the outer side of the handle 2, so that the positioning block 41 is stuck in the positioning groove 44. At this time, the arc-shaped block 42 is squeezed by the positioning groove 44 to compress the spring 43 and retract it into the positioning block 41. At this time, the positioning block 41 continues to move into the positioning groove 44. When the arc-shaped block 42 and the arc-shaped groove 45 are at the same level, the arc-shaped block 42 can be ejected from the positioning block 41 and stuck in the arc-shaped groove 45 by the resilience of the spring 43, so that the first sleeve 31 and the second sleeve 32 can be fixed on the outer side of the handle 2, and then the anti-slip sleeve 34 is passed through the position of the needle 1 and is sleeved in the limiting groove 33. Through the first sleeve 31 and the second sleeve 32, it is convenient for medical staff to hold the handle 2. Through the anti-slip sleeve 34 and the convex point 35, the friction between the palm of the medical staff and the first sleeve 31 and the second sleeve 32 can be increased to prevent the medical staff from slipping due to sweating on the palm.
