[0003] In the treatment of some diseases, a certain amount of stimulation is required to have a significant therapeutic effect, which means that some patients may need as many as 20 to 30 needles. The doctor who performs the acupuncture needs to pull out all the needles and discard them after the treatment. For the doctor, the process of pulling out the needles is a repetitive movement. In the process of pulling out the needles and throwing them into the waste bin, there is a risk that the needles will not be thrown into the waste bin and will be left on the treatment bed or the patient due to skin mucus, insufficient friction or static electricity. In addition, the repeated pulling out and collecting movements will lead to cumbersome operations. Summary of the invention

The present solution acts on the barrel of the quick needle extractor in a holding manner, aligns the position between the fastening claws of the barrel with the needle body and allows the top of the needle body to pass through the fastening claws. After starting the switch module, the control module is first used to control the first driving member to drive the fastening claw to move to the position between the multiple fastening claws, so that the fastening claw acts on the needle body and clamps the needle body. The control module is then used to control the second driving member to drive the movable member to slide upward along the guide member, so that the needle body clamped by the needle clamping mechanism that moves synchronously with the movable member also moves upward and detaches from the patient's skin. Finally, through the continuous movement of the movable member, the top of the needle body is inserted into the through hole of the guide member so that it enters the storage barrel for rapid storage. The setting of the quick needle extractor of the present solution can not only realize the automatic extraction of the needle body, but also can uniformly store the extracted needle bodies, making the quick needle extractor efficient and safe.

[0006] The second aspect of the present invention aims to solve the technical problem that the needle body cannot be slowly withdrawn from the patient's epidermis by rotating the needle body.

[0039] Example 2

[0040] like Figure 1-Figure 8 As shown, a first bearing 63 is arranged on the top of the guide member 6 of the present embodiment, and a turntable 8 is coaxially fixed on the upper end of the outer wall of the guide member 6. The guide member 6 is connected to the working cylinder 1 through the first bearing 63.

A second bearing 52 is provided between the movable member 5 and the displacement platform 73, and the second bearing 52 can be an end face ball bearing, so that the movable member 5 can rotate synchronously with the guide member without affecting the axial displacement.

[0042] like Figure 1-Figure 2 As shown, the quick needle puller of this embodiment adopts a cylindrical structure. In the actual operation process, the operator uses a gripping method to act on the needle puller. When using the needle puller, it is necessary to keep it as vertical as possible to the patient's body surface. A good gripping state can make the needle puller, and such a gripping method is both labor-saving and stable.

[0043] Example 3

[0044] like Figure 1-Figure 6 As shown, the first driving member 4 of this embodiment is a linear telescopic structure. The first driving member 4 is evenly distributed in the circumferential direction on the inner wall of the movable member 5. The first driving member 4 includes a driving part and a telescopic part. The output end of the telescopic part is connected to the fastening claw 3. The driving part synchronously drives the telescopic part so that the center of the fastening claw 3 is coaxial with the movable member 5.

[0045] like Figure 4-Figure 6 As shown, the needle clamping mechanism of this embodiment is provided with three fastening claws 3, and the fastening claws 3 are inclined surface pressing blocks, and the inner side of the inclined surface pressing blocks is an arc-shaped structure. The inclined surface pressing blocks include an upper inclined edge 31, a lower inclined edge 32, and a reinforcing plate 33 in the middle of the side of the inclined surface pressing blocks. The upper inclined edges 31 and the lower inclined edges 32 of the adjacent fastening claws 3 are arranged crosswise, and the reinforcing plate 33 is perpendicular to the inclined surface pressing blocks. By cross-arranging the inclined surfaces, the caliber formed between the fastening claws 3 can be reduced as the fastening claws 3 approach, until the needle body 100 is fastened and clamped, and the reinforcing plate 33 is arranged at the center position of the fastening claws 3, which can increase the axial contact area with the needle body 100, so that the needle body 100 is more stable after clamping and keeps coincidence with the axis under the action of multiple reinforcing plates 33 on the side, avoiding the needle body 100 from tilting.

[0046] like Figure 6 As shown, the inclination angle of the inclined pressure block is 20°~45°, the reinforcement pressure plate 33 is parallel to the axis of the working cylinder 1, and an arc-shaped groove is set on one side of the reinforcement pressure plate 33 that acts on the needle body. In order to make the three reinforcement pressure plates 33 of this embodiment abut against the needle body, the central angle of the arc-shaped groove is less than 120°.

[0047] The present embodiment also includes a positioning light belt and a positioning sensor inside the working cylinder 1 and an indicator light outside the working cylinder 1. The positioning light belt is arranged on the lower surface of the fastening claw 3. The positioning light belts between the plurality of fastening claws 3 form a closed positioning line.

The installation position of the positioning sensor on the movable inner wall is higher than the fastening claw 3. The positioning sensor is used to identify whether the top of the needle body 100 passes through the fastening claw 3. The positioning sensor is electrically connected to the indicator light. After the positioning sensor identifies the needle body 100, the indicator light emits a specified light.

[0048] A power source is provided in a vacant position in the working cylinder 1. In this embodiment, there is a gap between the mounting seat 74 above the second driving member 7 and the top surface of the working cylinder 1, and a battery for storing power is provided there. Multiple batteries can be installed on the side wall above the working cylinder. For the purpose of counterweight balance, multiple batteries are evenly and symmetrically arranged. An electrical socket is provided on the outside of the working cylinder so that the battery can be charged through external wiring.

[0049] Example 4

[0050] like Figure 1-Figure 2 As shown, in this embodiment, a magnetic component 21 is arranged in the storage tube 2. The magnetic component 21 is a radially magnetized annular magnet. The inner wall of the annular magnet is a receiving surface for magnetically attracting the needle body 100. The magnetic adsorption strength of the receiving surface is the largest. Multiple needle bodies 100 are adsorbed on the magnetic component 21 to form a needle body bundle.

[0051] Through radial magnetization, the inner wall of the annular magnet can be made the main action area of ​​the magnetic pole, and the magnetic pole of the inner wall can be strengthened to the maximum extent. When the needle body 100 enters the storage tube 2 and is magnetically adsorbed by the magnetic part 21, the needle body 100 is adsorbed from the center of the axis to the side wall of the annular magnet, so that the needle body 100 will not be directly adsorbed on the coaxial position of the magnetic part 21, and space is reserved for subsequent multiple adsorptions of the needle body 100.

[0052] A sheet magnet can also be arranged above the annular magnet to attract the needle body 100 into the storage tube at a coaxial position. Furthermore, in the actual operation process, when the needle body 100 extends into the through hole 62 of the guide member 6, there is still a distance from the interior of the storage tube 2. This distance can also be adjusted by the operator by slightly flipping the needle puller so that the needle body can slide into the storage tube 2 under the action of gravity and connect with the inner wall of the annular magnet under the adsorption action of the magnetic member 21.

[0055] like Figure 7 As shown, the unlocking mechanism is used to release the limiting effect of the positioning member 921 on the elastic ring 93. When the expansion frame 92 rotates toward the axial direction of the storage tube 2 under the action of the angle adjustment member, the elastic ring 93 mounted on the expansion frame 92 loses the constraint of the positioning member 921 and shrinks in the reset direction until the elastic ring 93 is separated from the expansion frame 92 and quickly mounted on the outside of the needle body bundle.

[0056] like Figure 8As shown, the positioning member 921 is a press-type lock 924, and the positioning member 921 includes a positioning lock tongue 923 and a lock buckle 924. A compression spring 925 is arranged between the positioning lock tongue 923 and the positioning lock buckle 924. The positioning lock tongue 923 is provided with a wedge-shaped limit block 922. By applying a force to the positioning lock tongue 923 to move the lock buckle 924, the positioning lock tongue 923 moves downward and is connected to the lock buckle 924, and the wedge-shaped limit block 922 on the top of the positioning lock tongue 923 loses the constraint on the elastic ring 93.

[0057] In order to enable the positioning member 921 to cooperate with the elastic ring 93 and achieve positioning, the positioning member 921 is installed on the side away from the axis of the expansion frame 92. The expansion frame 92 of this embodiment can adopt a rectangular or cylindrical structure, and the positioning members 921 are evenly installed in the extension direction of the expansion frame 92.

The lower end surface of the first rotating member is connected to the pushing member 941 through the third bearing 943, and the pushing member 941 is moved in the axial direction by rotating the first rotating ring 942.

[0061] The upper end surface of the working cavity 911 is provided with a first channel 914, which corresponds to the installation position of the expansion frame 92. The pushing member 941 passes through the first channel 914 and enters the working cavity 911 to abut against the inclined surface of the wedge-shaped limit block 922, and the positioning lock tongue 923 is pressed toward the lock buckle 924 through the pushing member 941.

[0062] like Figure 7As shown, the angle reset member 95 of this embodiment is installed on the lower connecting part 913, and the angle reset member 95 includes a pressure member 951, a second rotating ring 952 and a fourth bearing 953. The second rotating ring 952 is sleeved on the outer wall of the lower connecting part 913, and the lower connecting part 913 is threadedly connected to the second rotating ring 952. The lower end surface of the second rotating member is connected to the pressure member 951 through the fourth bearing 953, and the pressure member 951 is moved in the axial direction by rotating the second rotating ring 952.

[0063] A second channel 915 is provided on the lower end surface of the working chamber 911, and the second channel 915 corresponds to the installation position of the expansion frame 92. The pressure piece 951 passes through the second channel 915 and enters the working chamber 911 to abut against the inner side surface of the expansion frame 92. The expansion frame 92 is rotated upward by the pressure piece 951 so that the expansion frame 92 is rotated to be parallel to the axis.

[0064] The end of the pressure piece 951 abutting against the expansion frame 92 is an arc surface 954. The arc surface 954 is located in the abutting direction of the pressure piece 951 and the expansion frame 92; when the expansion frame 92 abuts against the maximum protruding position of the arc surface 954, the expansion frame 92 remains parallel to the axis.

[0065] Since the unlocking member 94 and the angle restoring member 95 act on both sides of the expansion frame 92 respectively, the first channel 914 and the second channel 915 provided in the working chamber 911 are staggered, and the unlocking member 94 and the angle restoring member 95 are also staggered.

[0066] In order to make the elastic ring 93 smoothly detach from the expansion frame 92 to bundle and pack the needle body bundle, first, the expansion frame 92 is kept horizontal with the axis under the restraining action of the angle reset member 95, and the first rotating ring 942 is rotated to make the pusher continuously pushed into the working chamber 911 along the first channel 914 until the pusher 941 abuts against the inclined surface of the wedge-shaped limit block 922 of the positioning member 921 of the expansion frame 92. Under the continuous movement of the pusher 941, the pusher 941 pushes the wedge-shaped limit block 922 into the lock buckle 924, and the positioning lock tongue 923 connected to the wedge-shaped limit block 922 is locked. At this time, the wedge-shaped limit block 922 is located below the tightening surface of the expansion frame 92 and the elastic ring 93, so that the wedge-shaped limit block 922 is no longer in contact with the elastic ring 93.

[0067] Secondly, by rotating the second rotating ring 952, the pressure piece 951 moves along the second channel 915 in the direction of leaving the working chamber 911, and then the expansion frame 92 loses the constraint of the angle reset piece 95. Under the action of the force in the contraction direction of the elastic ring 93, the expansion frame 92 rotates in the direction close to the axis. Since the upper elastic ring has lost the effect of the positioning piece 921, the elastic ring 93 slides along the inner wall of the expansion frame 92 until it is separated from the expansion frame 92. The separated elastic ring 93 quickly shrinks and is bundled on the outside of the needle body bundle for packaging. It is worth noting that when the unlocking piece 94 is working, it presses down the positioning piece 921 from top to bottom in sequence, and if the positioning piece 921 after being pressed down is not manually operated, it will not be reset, then the first rotating ring 942 can be rotated in one direction until the last positioning piece 921 on the expansion frame 92 is pressed; and the angle reset piece 95 needs to repeatedly adjust the angle of the expansion frame 92, then the second rotating ring 952 needs to be rotated forward and reverse alternately. Finally, the second rotating ring 952 is rotated in the reverse direction to move the pressure member 951 along the second channel 915 into the working chamber 911 , thereby resetting the expansion frame 92 .

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
