Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a handle and a therapeutic device. Background Technology
[0002] Thermage is a treatment device used for skin rejuvenation. In related technologies, Thermage includes a handpiece and an electrotherapy head. The handpiece contains a mounting base and a pressure sensor. The electrotherapy head is mounted on the handpiece via the mounting base. During use, the electrotherapy head is pressed against the skin surface. This causes the electrotherapy head to move along with the mounting base, contacting and abutting against the pressure sensor. The pressure sensor then monitors the pressure applied by the electrotherapy head to the skin in real time, ensuring the treatment effect. However, in actual use, the pressure sensor may be damaged if the user applies excessive force during the installation of the electrotherapy head or when pressing it against the skin surface. Utility Model Content
[0003] The main objective of this invention is to provide a handle and a therapeutic device designed to reduce the risk of pressure sensor damage.

[0007] The mounting base is movably disposed within the receiving cavity, the mounting base elastically abuts against the detection end, and the end of the mounting base away from the detection end is exposed in the opening and is used to mount the electrotherapy head.
[0008] In one embodiment, the handle further includes an elastic element disposed at one end of the mounting base near the detection end, and the other end of the elastic element away from the mounting base is connected to the detection end.
[0009] In one embodiment, the end of the mounting base facing the detection end has a receiving groove, and the end of the elastic member away from the detection end is located in the receiving groove.
[0010] In one embodiment, the handle further includes an abutment portion disposed at one end of the elastic member near the detection end and abutting against the detection end;
[0011] The contact portion is elongated or cylindrical.
[0012] In one embodiment, a receiving groove is formed at the end of the mounting base facing the detection end;
[0013] The handle also includes a sleeve disposed in the receiving groove. A mounting groove is formed at one end of the sleeve facing the detection end. The elastic element is disposed in the mounting groove, and the abutment portion is slidably disposed in the mounting groove.
[0014] In one embodiment, the bottom wall of the receiving groove has a through hole;
[0015] The sleeve includes a connected cylindrical body and a connecting section, the cylindrical body forming the mounting groove, the cylindrical body being confined within the receiving groove, and the connecting section passing through the through hole;
[0016] The handle also includes a retaining ring, which is sleeved on the end of the connecting section away from the cylinder, and the retaining ring fits against the periphery of the end of the through hole away from the mounting groove.
[0017] In one embodiment, the pressure sensor includes a protrusion disposed at the detection end, the detection end having a stop surface disposed around the protrusion;
[0018] The elastic element is connected to the protrusion, and the stop surface is used to stop and limit the end face of the mounting base facing the detection end.
[0019] In one embodiment, the handle further includes a vibration motor and a damping element. The vibration motor is disposed on the mounting base, and the damping element connects the mounting base and the housing. The damping element is disposed close to the vibration motor.

[0022] In the technical solution of this utility model, the mounting base can elastically abut against the detection end. Thus, when the electrotherapy head is installed or when the electrotherapy head presses on the skin, the electrotherapy head drives the mounting base to move closer to the pressure sensor, thereby causing the mounting base to press on the detection end and undergo elastic deformation. The elastic deformation can absorb part of the pressure of the mounting base on the detection end, that is, reduce the pressure on the detection end and reduce the risk of damage to the pressure sensor.

[0033] This utility model proposes a handle 100.
[0034] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the handle 100 includes a housing 1, a pressure sensor 2, and a mounting base 3; the housing 1 forms a receiving cavity with an opening; the pressure sensor 2 is disposed in the receiving cavity and has a detection end 23; the mounting base 3 is movably disposed in the receiving cavity, the mounting base 3 elastically abuts against the detection end 23, and one end of the mounting base 3 away from the detection end 23 is exposed in the opening and is used to mount the electrotherapy head 4.
[0035] In the technical solution of this utility model, the mounting base 3 can elastically abut against the detection end 23. Thus, when the electrotherapy head 4 is installed or when the electrotherapy head 4 presses against the skin, the electrotherapy head 4 drives the mounting base 3 to move closer to the pressure sensor 2, thereby causing the mounting base 3 to press against the detection end 23 and undergo elastic deformation. The elastic deformation can absorb part of the pressure of the mounting base 3 on the detection end 23, that is, reduce the pressure on the detection end 23 and reduce the risk of damage to the pressure sensor 2.
[0036] There are several ways to elastically abut the mounting base 3 against the detection end 23. For example, a component made of elastic material can be provided on the mounting base 3 to abut against the detection end 23, allowing the component to elastically deform and absorb part of the pressure exerted by the mounting base 3 on the detection end 23. In one embodiment of this utility model, the handle 100 also includes an elastic element 5. The elastic element 5 is located at the end of the mounting base 3 near the detection end 23, and the end of the elastic element 5 away from the mounting base 3 is connected to the detection end 23. The elastic element 5 can be in direct contact with the detection end 23, or it can be in indirect contact with the detection end 23 through other objects. As long as the mounting base 3 moves closer to the pressure sensor 2, the elastic element 5 can abut against the detection end 23 and be compressed and deformed, thereby absorbing part of the pressure exerted by the mounting base 3 on the detection end 23, thus reducing the pressure directly acting on the detection end 23 and lowering the risk of damage to the pressure sensor 2. When the mounting base 3 moves away from the pressure sensor 2, the elastic element 5 can return to its original shape. The elastic element 5 is preferably a spring, but rubber pads or silicone pads or other elastic materials can also be used.
[0037] Furthermore, in one embodiment of this utility model, a receiving groove 301 is formed at the end of the mounting base 3 facing the detection end 23, and the end of the elastic member 5 away from the detection end 23 is located within the receiving groove 301. The receiving groove 301 provides a specific installation position for the elastic member 5, making the installation and replacement of the elastic member 5 more convenient; the receiving groove 301 can also restrict the position of the elastic member 5 during the movement of the mounting base 3, preventing the elastic member 5 from shifting and failing to accurately abut against the detection end 23, thereby ensuring that the pressure sensor 2 can receive an accurate pressure signal, and thus ensuring the accuracy of treatment. In addition, by providing a receiving groove 301 on the mounting base 3 facing the detection end 23 and placing the end of the elastic member 5 away from the detection end 23 within the receiving groove 301, the additional space required for the elastic member 5 can be reduced, the external space occupied can be reduced, and the structure within the housing 1's receiving cavity can be made more compact, which helps to reduce the overall volume of the handle 100. In this configuration, a portion of the elastic element 5 may be exposed outside the receiving groove 301, allowing the elastic element 5 to directly contact the detection end 23. Alternatively, the elastic element 5 may be completely contained within the receiving groove 301, making indirect contact with the detection end 23 through other objects. The dimensions of the receiving groove 301 can be adjusted according to the dimensions of the elastic element 5, thereby meeting the installation and usage requirements of elastic elements 5 of different sizes.
[0038] It is understandable that when the elastic element 5 is a spring, the contact area between the spring and the detection end 23 is limited, which may lead to inaccurate pressure transmission and affect the measurement results. In order to ensure accurate contact with the detection end 23, in one embodiment of this utility model, please refer to... Figure 2 and Figure 3The handle 100 also includes an abutment portion 6, which is located at the end of the elastic member 5 near the detection end 23 and abuts against the detection end 23. The specific structure of the abutment portion 6 can be designed according to the structure of the detection end 23, so that when it abuts against the detection end 23, it has a larger contact area or a more uniform contact point, which can accurately transmit pressure to the pressure sensor 2 and improve the response speed and accuracy of the pressure sensor 2. In this embodiment, the abutment portion 6 is elongated or cylindrical, both of which have good guiding properties and are easy to manufacture.
[0039] To limit the direction of movement of the abutment portion 6, please refer to one embodiment of this utility model. Figure 2 and Figure 3 The mounting base 3 has a receiving groove 301 at one end facing the detection end 23; the handle 100 also includes a sleeve 7, which is disposed in the receiving groove 301. The sleeve 7 has a mounting groove 701 at one end facing the detection end 23. The elastic member 5 is disposed in the mounting groove 701, and the abutment part 6 is slidably disposed in the mounting groove 701. By setting the sleeve 7 and sliding the abutment 6 in the mounting groove 701, the sleeve 7 restricts the movement direction of the abutment 6. When the mounting base 3 moves closer to the detection end 23, the abutment 6 abuts against the detection end 23 and slides relative to the side wall of the mounting groove 701 under the restriction of the sleeve 7, compressing the spring. This absorbs some of the pressure from the mounting base 3 on the detection end 23, reducing the pressure directly acting on the detection end 23 and lowering the risk of damage to the pressure sensor 2. When the mounting base 3 moves away from the detection end 23, the abutment 6, under the elastic force of the spring, slides relative to the side wall of the mounting groove 701 under the restriction of the sleeve 7. Thus, the movement direction of the abutment 6 is fixed, providing more accurate pressure to the detection end 23. Furthermore, since the elastic element 5 and the abutment 6 are both integrated into the sleeve 7, the sleeve 7 can be directly disassembled for maintenance or replacement, simplifying the maintenance or replacement process. The sleeve 7 and the abutment 6 also protect the elastic element 5 from damage or contamination from external factors, helping to extend the service life of the elastic element 5.
[0040] Specifically, in one embodiment of this utility model, please refer to Figure 3The bottom wall of the receiving groove 301 has a through hole; the sleeve 7 includes a connected cylindrical body 71 and a connecting section 72. The cylindrical body 71 forms a mounting groove 701 and is confined within the receiving groove 301. The connecting section 72 passes through the through hole; the handle 100 also includes a retaining ring 8, which is fitted onto the end of the connecting section 72 away from the cylindrical body 71. The retaining ring 8 fits against the periphery of the end of the through hole away from the mounting groove 701. The through hole and the retaining ring 8 make the installation of the sleeve 7 more convenient. Simply pass the connecting section 72 through the through hole and then install the retaining ring 8 on the connecting section 72, without the need for additional fasteners; maintenance and replacement are also more convenient. At the same time, the retaining ring 8 can limit the position of the connecting section 72, ensuring that the cylindrical body 71 can always be confined within the receiving groove 301.
[0041] To limit the range of motion of the mounting base 3, please refer to one embodiment of this utility model. Figure 3 The pressure sensor 2 includes a protrusion 21 located at the detection end 23, and the detection end 23 has a stop surface 22 surrounding the protrusion 21. An elastic member 5 is connected to the protrusion 21, and the stop surface 22 is used to stop and limit the end face of the mounting base 3 facing the detection end 23. The protrusion 21 is configured as a small hemispherical protrusion structure, which can achieve contact with the elastic member 5 in a small space. Furthermore, by adjusting the protrusion height of the protrusion 21, it can be adapted to different detection requirements. The stop surface 22 can limit the range of motion of the mounting base 3. That is, when the end face of the mounting base 3 facing the detection end 23 contacts the stop surface 22, the mounting base 3 cannot continue to move closer to the detection end 23, thereby limiting the maximum stroke of the mounting base 3 and preventing damage to the pressure sensor 2 due to the pressure of the mounting base 3 on the protrusion 21 exceeding the buffer range of the elastic member 5, thus improving the safety of the handle 100.
[0042] Furthermore, in one embodiment of this utility model, please refer to... Figure 2 The handle 100 also includes a vibration motor 9 and a damping element. The vibration motor 9 is mounted on the mounting base 3, and the damping element connects the mounting base 3 and the housing 1, with the damping element positioned close to the vibration motor 9. When the electrotherapy head 4 is installed on the handle 100 to treat a patient, pain may occur. At this time, the vibration of the vibration motor 9 can be transmitted through the electrotherapy head 4 to the skin being pressed by the electrotherapy head 4, thereby producing a kneading effect on the skin and muscles to reduce the patient's pain. However, the vibration motor 9 also causes the housing 1 to vibrate, affecting the user's grip and use. In this case, the damping element connects the mounting base 3 and the housing 1, and the energy generated by the vibration of the vibration motor 9 is transmitted to the housing 1 through the damping element. The damping element can absorb some of the energy, reducing the energy transmitted to the housing 1, thus effectively reducing the vibration of the housing 1 and making it easier to grip and use.
[0043] Specifically, in one embodiment of this utility model, please refer to... Figure 2The vibration damping component is a damping spring 10. One end of the damping spring 10 is connected to the end of the mounting base 3 away from the detection end 23, and the other end of the damping spring 10 is connected to the end of the mounting base 3 near the detection end 23. The middle part of the damping spring 10 is connected to the housing 1. The energy generated by the vibration of the vibration motor 9 is transmitted to the housing 1 through both ends of the damping spring 10. During the transmission process, the damping spring 10 undergoes elastic deformation to absorb energy. That is, the energy generated by the vibration of the vibration motor 9 is converted into the elastic potential energy of the damping spring 10, thereby reducing the energy transmitted to the housing 1, effectively reducing the vibration of the housing 1, and making it easier to hold and use. The middle part of the damping spring 10 is connected to the housing 1 by screws.
[0044] This utility model also proposes a therapeutic device, which includes a handle 100 and an electrotherapy head 4. The electrotherapy head 4 is located at the end of the mounting base 3 away from the detection end 23. The specific structure of the handle 100 is as described in the above embodiments. Since this therapeutic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
