Embodiment 1

As shown in Figures 1 and 2, the embodiment of the present application provides a friction twister including a housing 1, a driving component 2 and a twisting component 3. The driving assembly 2 is fixedly installed on the housing 1 . The twisting component 3 includes a first plywood 31, a mounting groove 32 and a second plywood 33. The first plywood 31 is connected to the housing 1. The mounting groove 32 is opened in the first plywood 31 and extends along the first direction. The second plywood 33 is passed through the housing 1 and is arranged parallel to the first clamping plate 31. It is also configured to reciprocate in the second direction driven by the driving assembly 2 to drive the millimeter needle in the installation slot 32 to rotate; wherein, in the first direction perpendicular to the second direction.

It should be noted here that the above and below first directions refer to directions consistent with the rotation axis of the driving assembly 2, specifically the X-axis as shown in Figure 1. The second directions above and below refer to the shortest connection direction between the end of the second clamping plate 33 close to the driving assembly 2 and the end of the second clamping plate 33 away from the driving assembly 2 , specifically the Y-axis as shown in Figure 1 .

Among them, in the related technology, after the filiform needle is inserted into the acupuncture point of the human body, the filiform needle is fixed to the twister through the clamping device, and the twister transmits the circumferential motion of the motor output shaft to the clamping device through the transmission device. This drives the filiform needle to rotate. However, when the filiform needle is fixed by the clamping device, the axis of the filiform needle will deviate from the rotation axis of the transmission device. During the twisting process, the rotation radius of the filiform needle will easily increase, which will increase the patient's pain, and Medical accidents are prone to occur.

Specifically, when inserting the filiform needle into the patient's acupuncture point, first remove the second splint 33 from the housing 1, then put the tail of the filiform needle into the installation groove 32, and finally install the second splint 33 to the shell. On the body 1, at this time, the filiform needle is located between the first splint 31 and the second splint 33. The driving assembly 2 is started, and the driving assembly 2 drives the first clamping plate 31 to reciprocate in the second direction, that is, the first clamping plate 31 reciprocates relative to the second clamping plate 33 in the second direction. The reciprocating movement of the second clamping plate 33 generates friction between the first clamping plate 31 and the second clamping plate 33 , thereby driving the millimeter needle in the mounting groove 32 on the first clamping plate 31 to rotate.

It should be noted here that in this embodiment, the cross section of the mounting groove 32 perpendicular to the first direction is arranged in a fan shape as an example.

In the friction twister provided by this application, the driving component 2 drives the second splint 33 to reciprocate in the second direction, which can drive the filiform needle in the installation slot 32 to rotate, thereby twisting the filiform needle and stimulating the patient's acupoints. Moreover, the millimeter needle can be positioned through the mounting groove 32 so that the millimeter needle can only rotate around the axial direction of the mounting groove 32. Since the position of the mounting groove 32 is fixed, the deviation between the axis and the rotation axis of the driving assembly 2 can be eliminated, and there is Helps improve the twisting stability of the twister and prevent medical accidents. In addition, the second splint 33 reciprocates along the second direction and can drive the filiform needle to reciprocate around the first direction. This can imitate the acupuncture method of twisting the filiform needle by medical staff and help improve the treatment effect of the twister.

Optionally, the arc of the sector is greater than 180°.

Specifically, in this embodiment, the radian of the sector is set to 240° as an example for description.

Specifically, in this embodiment, the cam 22 has a first end (not shown in the figure) and a second end (not shown in the figure). The distance between the first end of cam 22 and the axis of rotation of cam 22 is less than the distance between the second end of cam 22 and the axis of rotation of cam 22 . When the driving assembly 2 drives the cam 22 to rotate, both the first end of the cam 22 and the second end of the cam 22 rotate around the rotation axis of the rotating motor 21 . When the second clamping plate 33 changes from being in contact with the first end of the cam 22 to being in contact with the second end of the cam 22 , the cam 22 can drive the second clamping plate 33 to move away from the rotating motor 21 .

With this arrangement, the second clamping plate 33 can be driven to move away from the rotating motor 21 in the second direction by taking advantage of the different distances between the outer circumferential side of the cam 22 and the rotation axis of the cam 22, thereby driving the millimeter needle along the first direction. Rotate in one direction.

When the second clamping plate 33 contacts the second end of the cam 22, the elastic member 23 is in the second compressed state. The compression amount in the first compression state is less than the compression amount in the second compression state, that is, the length of the elastic member 23 in the first compression state is greater than the length of the elastic member 23 in the second compression state, so that the elastic member 23 is in the first compression state. The elastic potential energy stored in the compressed state is also smaller than the elastic potential energy stored by the elastic member 23 in the second compressed state.

When the cam 22 changes from the first end in contact with the second clamping plate 33 to the second end in contact with the second clamping plate 33 , the second clamping plate 33 gradually moves away from the rotating motor 21 , the elastic member 23 is gradually compressed, and is compressed from the first The state changes to the second compression state while elastic potential energy is stored until the second end of the cam 22 contacts the second clamping plate 33 . When the cam 22 changes from the second end in contact with the second clamping plate 33 to the first end in contact with the second clamping plate 33, the elastic member 23 gradually stretches and changes from the second compression state to the first compression state, and simultaneously releases the stored energy.

The plate 232 moves away from the rotating motor 21 in the second direction, the elastic structure 233 and the telescopic rod 231 are compressed under the action of the push plate 232, and the elastic structure 233 stores elastic energy until the second clamping plate 33 and the second end of the cam 22 touch.

When the cam 22 changes from the second end in contact with the second clamping plate 33 to the first end in contact with the second clamping plate 33 , the elastic structure 233 releases elastic potential energy, driving the push plate 232 to move toward the rotating motor 21 , and the telescopic rod 231 moves on the push plate 232 Gradually elongated under the action of , the push plate 232 can also push the second clamping plate 33 to gradually move toward the rotating motor 21 .
