Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a skin treatment roller needle. Background Art

[0002] Roller therapy is mainly a project for repairing and improving the skin.

[0003] The needles of skin treatment rollers are usually fixed in structure, and the length of the rollers cannot be adjusted, which makes them less versatile.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the utility model provides a skin treatment needle roller, including a roller 1, a mounting frame 2 rotatably connected to the roller 1, and a handle 3 connected to the mounting frame 2. A first cavity 21 is provided inside the mounting frame 2, and a second cavity 31 communicating with the first cavity 21 is provided inside the handle 3. The skin treatment needle roller also includes a support assembly 5, a needle roller 11, and a piston rod 4. The support assembly 5 is provided inside the roller 1. The support assembly 5 at least includes an airbag 51, and the airbag 51 is communicated with the first cavity 21; one end of the needle roller 11 is connected to the airbag 51, and the other end passes through the roller 1 and protrudes from the outer peripheral surface of the roller 1. A plurality of needle rollers 11 are provided and are spaced and distributed on the outer peripheral surface of the roller 1; the piston rod 4 is inserted in the second cavity 31 and can perform piston motion in the second cavity 31. When the piston rod 4 performs piston motion in the second cavity 31, the airbag 51 can be driven to expand or contract.

[0043] In the skin treatment needle roller 11 of the utility model, multiple needle rollers 11 protrude from the outer circumference of the roller 1. The handle 3 is held and the roller 1 is rolled on the patient's skin, so that the patient's skin can be treated with the needle roller 11. The first cavity 21, the second cavity 31 and the cavity inside the airbag 51 are connected. When the piston rod 4 is pushed to make a piston movement, the air pressure inside the three cavities can be changed, thereby driving the airbag 51 to expand or contract, and then driving the needle rollers 11 connected to the airbag 51 to expand and contract, so that the length of the needle rollers 11 protruding from the outer circumference of the roller 1 changes, and the length of the needle rollers 11 is adjusted.

[0044] The following is a detailed description of the various parts of a skin treatment roller needle provided by the embodiment of the utility model in conjunction with the accompanying drawings:

[0045] In the implementation mode of the present utility model, Figure 1 , Figure 2 As shown, the skin treatment needle roller includes a roller 1, a mounting frame 2 and a handle 3. The roller 1 is rotatably connected to the mounting frame 2, and the handle 3 can be fixedly connected to the mounting frame 2. The roller 1 can be rolled by holding the handle 3. Specifically, the mounting frame 2 can include two symmetrically arranged side arms, and the two side arms form a U-shaped mounting frame 2. The roller 1 is located inside the U-shaped mounting frame 2, and the two sides of the roller 1 are respectively rotatably connected to the two side arms, and the handle 3 is fixedly connected to the middle of the mounting frame 2 away from the roller 1.

[0046] Meanwhile, a first cavity 21 is disposed inside the mounting frame 2 , and a second cavity 31 is disposed inside the handle 3 . The first cavity 21 and the second cavity 31 are communicated with each other.

[0047] The skin treatment needle roller also includes a support assembly 5, a needle roller 11 and a piston rod 4. The support assembly 5 is arranged inside the roller 1, and the support assembly 5 at least includes an airbag 51, which is connected to the first cavity 21; one end of the needle roller 11 is connected to the airbag 51, and the other end passes through the roller 1 and protrudes from the outer peripheral surface of the roller 1, and multiple needle rollers 11 are distributed at intervals on the outer peripheral surface of the roller 1; the piston rod 4 is movably inserted in the second cavity 31, and it can make piston motion in the second cavity 31. Therefore, the first cavity 21, the second cavity 31 and the internal cavity of the airbag 51 are connected, and the piston rod 4 seals the three cavities. When the piston rod 4 makes a piston motion, the air pressure inside the three cavities can be changed, so that the airbag 51 can expand or contract, and then the length of the needle roller 11 protruding from the outer peripheral surface of the roller 1 can be changed, so as to adjust the length of the needle roller 11. Furthermore, the plurality of needle rollers 11 are all connected to the airbag 51 . When the airbag 51 expands or contracts, the plurality of needle rollers 11 can be driven to move, thereby realizing rapid adjustment of the length of the needle rollers 11 .

[0048] Furthermore, the support assembly 5 also includes a support bar 52, which is fixedly connected to the airbag 51, and the multiple needle rollers 11 in the same row are all fixed on the support bar 52. Specifically, the multiple needle rollers 11 are evenly spaced along the outer circumference of the roller 1, and the multiple needle rollers 11 in the same row along the axial direction of the roller 1 are all fixed on the same support bar 52, so that there are multiple support bars 52 evenly spaced around the circumference of the roller 1, and the support bar 52 is fixed on the airbag 51. Therefore, when the airbag 51 expands or contracts, the airbag 51 can drive the support bar 52 to move, thereby realizing the extension and retraction of the needle rollers 11. In addition, the support bar 52 can make the needle rollers 11 in the same row extend and retract at the same time, ensuring that the lengths of the multiple needle rollers 11 protruding from the outer circumference of the roller 1 are consistent, thereby ensuring the safety and therapeutic effect of the treatment.

[0049] Furthermore, a positioning bolt 41 is sleeved on the piston rod 4. After the piston rod 4 moves to the specified position, the positioning bolt 41 is screwed on the handle 3 to limit the piston movement of the piston rod 4. For example, a socket for inserting the piston rod 4 is provided at the end of the handle 3 away from the roller 1. The socket is connected to the second cavity 31. The hole wall of the socket is processed with threads screwed with the positioning bolt 41, and the diameter of the socket gradually decreases toward the direction close to the roller 1; the positioning bolt 41 is sleeved on the piston rod 4 and the positioning bolt 41 is processed with threads. The threaded part of the positioning bolt 41 is provided with two notches along the axis. When the piston rod 4 moves to the specified position, the positioning bolt 41 is screwed into the socket. During the screwing process, the positioning bolt 41 is gradually squeezed, so that the positioning bolt 41 squeezes the piston rod 4, and the position of the piston rod 4 is fixed, which is convenient for the staff to operate, and avoids the expansion or contraction of the airbag 51 during the needle roller treatment, which causes the length of the needle roller 11 to change, and effectively ensures the safety of the treatment process.

[0050] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, two airbags 51 may be provided, and are symmetrically arranged at both ends of the roller 1. The first cavities 21 are provided inside the two side arms of the mounting frame 2, and the two airbags 51 are respectively connected to the first cavities 21 inside the two side arms. The support bar 52 is fixedly connected to the two airbags 51, and the sum of the thicknesses of the two airbags 51 after they are fully expanded is less than the length of the roller 1, which is conducive to improving the stability of the airbag 51 supporting the support bar 52 and the roller needle 11. Of course, in order to further improve the support of the airbag 51, the airbag 51 can be made of a plastic material with a higher hardness, and the utility model does not make any special restrictions on this.

[0051] Preferably, a bearing can be provided at the rotation connection between the side arm frame and the roller 1. The bearing can make the rotation between the roller 1 and the side arm frame smoother, while ensuring that the connection between the first cavity 21 and the airbag 51 is not affected by the rotation of the roller 1.

[0052] In one embodiment of the present invention, Figure 3 , Figure 4 As shown, the skin treatment needle roller 11 also includes a limiting component, which is used to limit the moving distance and moving length of the support bar 52, so that the length of the needle roller 11 can be adjusted within a specified range. For example, the limiting component includes a limiting protrusion 521 and a limiting groove 12. The limiting protrusion 521 is a protrusion protruding from both ends of the support bar 52, and the limiting groove 12 is provided on two opposite side walls inside the roller 1. The limiting protrusion 521 is located in the limiting groove 12 and the limiting groove 12 is adapted to the limiting protrusion 521. When the airbag 51 expands or contracts, it drives the support bar 52 to move, so that during the movement of the support bar 52, the limiting protrusion 521 slides in the limiting groove 12, so that the support bar 52 can move along the track of the limiting groove 12, which can effectively prevent the needle roller 11 from deflecting during the extension and retraction process.

[0053] Furthermore, the limiting groove 12 is extended and opened along the radial direction of the roller 1, so that the support bar 52 can be limited to move along the roller 1 when moving, so that the direction of the needle roller 11 will not swing when extending or retracting, effectively improving the consistency and stability of the length adjustment of the needle roller 11. At the same time, by limiting the length of the limiting groove 12, the length adjustment range of the needle roller 11 can be controlled. The length of the limiting groove 12 is not specifically limited in the present invention.

[0054] In an exemplary embodiment of the utility model, the skin treatment needle roller further includes a locking portion 13, which can be arranged in the limiting groove 12. After the support bar 52 moves to the specified position, the locking portion 13 can limit the sliding of the limiting protrusion 521. For example, the needle roller 11 has two length adjustment requirements, so that when the limiting protrusion 521 slides to one end of the limiting groove 12 away from the center of the roller 1, the length of the needle roller 11 is adjusted to the longest, and when the limiting protrusion 521 slides to the other end, the length of the needle roller 11 is adjusted to the shortest. The locking portion 13 can be an arc-shaped protrusion arranged on the groove wall of the limiting groove 12. When the limiting protrusion 521 slides to one end of the limiting groove 12, the arc-shaped protrusion can block the sliding of the limiting protrusion 521 to the other end, which can effectively avoid the change of the length of the needle roller 11 caused by the elastic deformation of the airbag 51 during the treatment process of the needle roller 11, and can further improve the stability of the support bar 52 for the needle roller 11.

[0055] Furthermore, a scale for observing the moving distance of the piston rod 4 is provided on the handle 3. Specifically, the second cavity 31 inside can be observed from the outside of the handle 3. During production, the inflation degree of the airbag 51 caused by the piston rod 4 moving a specified distance can be adjusted and reflected on the handle 3 in the form of a scale, thereby facilitating the operation of the staff.

[0056] In another exemplary embodiment of the present invention, anti-slip grooves are provided on the handle 3, which can improve the comfort and anti-slip property of the staff when holding the handle 3 for roller needle treatment.

[0057] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. The present invention is intended to cover any variation, use or adaptation of the present invention, which follows the general principles of the present invention and includes common knowledge or customary technical means in the art that are not disclosed in the present invention.
