Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a skin needle. Background Technology

[0002] Dermal needles are an important tool widely used in acupuncture, massage, and the treatment of skin diseases. However, traditional dermal needles have some drawbacks in use. First, because human skin has a certain angle of inclination, the angle of the needle needs to be adjusted to suit different usage scenarios. Second, the density of the needle significantly affects the acupuncture effect, thus requiring adjustment to meet different treatment needs. Furthermore, for acupuncture treatments on different sites and for different diseases, the insertion angle of the needle needs to be adjusted to achieve better therapeutic results.

[0003] Traditional dermal needles typically employ a fixed design, lacking adjustable tilt angle, density, and insertion angle. This makes them unsuitable for various usage scenarios and treatment needs, leading to inconsistent results and varying treatment outcomes. Furthermore, the inability to adjust the insertion angle results in uneven force distribution during operation, easily causing hand fatigue and discomfort for the operator.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-10 The present invention provides a skin needle, comprising:

[0041] The handle assembly has a base 1 rotatably connected to its top, and the base 1 and the handle assembly are detachably connected via a limit knob 22.

[0042] The tilt adjustment mechanism includes a first replacement seat 2 and a tilt adjustment assembly. A plurality of needles 3 are rotatably connected to the first replacement seat 2, and the tilt adjustment assembly is used to adjust the tilt angle of the plurality of needles 3.

[0043] The density adjustment mechanism includes a second replacement seat 4, a turntable assembly, and several sector-shaped connecting plates 5; the turntable assembly is rotatably connected between the second replacement seat 4 and several sector-shaped connecting plates 5, and is used to adjust the spacing between the several sector-shaped connecting plates 5; the several sector-shaped connecting plates 5 enclose a circular structure, and several needles 3 are installed on the sector-shaped connecting plates 5.

[0044] The first replacement seat 2 and the second replacement seat 4 are both detachably connected to the base 1;

[0045] With this design, the handle assembly of this invention facilitates gripping and use by the operator. The limiting knob 22 allows for easy adjustment of the tilt angle of the base 1, thereby adjusting the overall tilt angle of the needle body 3, adapting to different usage scenarios. When adjusting the needling angle of the needle body 3, the tilt angle adjustment mechanism is installed on the base 1, and the tilt angle of several needle bodies 3 is adjusted via the tilt angle adjustment component, thus changing the angle of the needle body 3 and adjusting the needling angle. When adjusting the density of the needle body 3, the density adjustment mechanism is installed on the base, and the spacing of several fan-shaped connecting plates 5 is adjusted via the turntable assembly, thus adjusting the density of the needle body 3. This invention can achieve adjustment of the tilt angle, density, and needling angle of the dermal needle, adapting to different usage scenarios, and ensuring uniform force distribution, thus improving the effectiveness of use.

[0046] The scheme is further optimized, and the tilt adjustment component includes an adjustment plate 6 and a limiting part; the adjustment plate 6 is detachably connected to the first replacement seat 2 through the limiting part;

[0047] The adjusting plate 6 is located above the first replacement seat 2. The adjusting plate 6 has several strip holes 7. Several needles 3 on the first replacement seat 2 pass through several strip holes 7 respectively, and the top of the needles 3 extends out of the adjusting plate 6. The size of the strip holes 7 is adapted to the size of the needles 3.

[0048] With this setup, by moving the adjustment plate 6, several needles 3 can be moved to adjust the needling angle simultaneously. After the adjustment is completed, the position is fixed by the limiting part, and then subsequent skin needling operations can be performed.

[0049] Further optimization of the scheme: a threaded hole 8 is provided on the side wall of the first replacement seat 2; the limiting part includes a connecting wing 9 and a positioning bolt 10; the connecting wing 9 is fixedly installed on the bottom of the adjusting plate 6; the positioning bolt 10 is installed on the connecting wing 9; and the positioning bolt 10 is threadedly connected to the threaded hole 8.

[0050] With this configuration, the position between the adjusting plate 6 and the first replacement seat 2 can be fixed by connecting the positioning bolt 10 to the threaded hole 8, thereby fixing the needle piercing angle.

[0051] Further optimization of the solution includes the following turntable components:

[0056] The connecting plate 17 is fixedly connected to the bottom surface of the fan-shaped connecting plate 5, and several connecting plates 17 and several fan-shaped connecting plates 5 are arranged in a one-to-one correspondence; a driving block 18 is fixedly connected to the connecting plate 17, the driving block 18 is slidably connected to the arc groove 15, and several driving blocks 18 are arranged in a one-to-one correspondence with several arc grooves 15; a limiting part is provided on the inner wall of the arc groove 15.

[0057] With this configuration, when in use, rotating the drive shaft of the drive gear 13 drives the driven gear 14 to rotate, which in turn drives the drive rod 16 to slide in the arc groove 15 and move outward, thereby driving several fan-shaped connecting plates 5 to move outward along the center of the driven gear 14, thus realizing the adjustment of the spacing of several fan-shaped connecting plates 5, and thus realizing the adjustment of the density of the needle body 3.

[0058] Further optimization of the scheme: the cross-section of the drive block 18 is circular; the limiting part includes several limiting protrusions 19, which are fixed at equal intervals on the groove wall of the arc groove 15; by setting several limiting protrusions 19, the drive rod 16 can be limited between two adjacent limiting protrusions 19 during the sliding process in the arc groove 15, thereby realizing the position limitation of the drive rod 16 at different positions in the arc groove 15, thereby realizing the position fixation of density adjustment.

[0059] The design is further optimized. The handle assembly includes a connecting handle 20 and a ring finger sleeve 21.

[0061] In a further optimized design, several snap-fit ​​blocks 23 are fixedly attached to the top surface of the base 1, and several snap-fit ​​grooves 24 are provided on the bottom surface of the first replacement seat 2 and the bottom surface of the second replacement seat 4. The snap-fit ​​blocks 23 snap into the several snap-fit ​​grooves 24, and the several snap-fit ​​blocks 23 and several snap-fit ​​grooves 24 are set in a one-to-one correspondence.
