DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Hereinafter, a handpiece for a treatment device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the embodiment, the names of the components may be called by other names in the art. However, if there is functional similarity and identity between the components, the modified embodiment may be considered as an equivalent configuration. Furthermore, the reference numerals attached to the components are described for convenience of description. However, the illustrated contents in the drawings in which the reference numerals are described do not limit the respective components to the scope of the drawings. Similarly, if an embodiment in which the configuration in the drawings is partially modified is adopted, the modified embodiment may be considered as an equivalent configuration if there is functional similarity and identity between the components. Furthermore, if a component is considered to be included in the present invention in view of the general level of a technician in the relevant technical field, the description thereof will be omitted.

[0031] FIG. 1 is a perspective view of a treatment device including a handpiece 10 according to one embodiment of the present disclosure.

[0032] 1, a handpiece 10 according to the present disclosure can be configured to perform a therapeutic operation by being connected to a treatment device 1. In the present disclosure, the treatment device can include a handpiece 10 provided with a main body 2 and connected to the main body 2 via a cable 3.

[0033] If the main body 2 of the treatment device 1 is a type that performs treatment by generating a laser, it may be configured to include optical elements such as a Q-switched laser (not shown), a laser emitter (not shown), a beam distributor (not shown), a wave plate, a second harmonic generator (not shown), etc. Meanwhile, if the treatment device is a type that performs treatment using RF energy, it may be provided internally with an RF generator (not shown), an RF energy regulator (not shown), a controller (not shown), etc.

[0034] Meanwhile, the above-mentioned treatment method is merely an example, and can be applied to various types of energy transmitting devices such as HIFU (High intensive focused ultrasound).

[0035] The outside of the main body 2 may include various input units for controlling the device, a display unit for monitoring the current status, and a handpiece holder 4 for mounting a handpiece. Such a treatment device 1 may typically include a ring at the bottom for easy positional movement.

[0036] The handpiece 10 is configured to be held by the hand of a medical team (user) for use. The handpiece 10 is configured to receive energy generated in the main body 2 and transmit it to skin tissue. A cable 3 is connected to the rear side of the handpiece 10 so that the handpiece 10 can receive power, an energy source, and a coolant from the main body 2. A tip module 700 is provided at the front end of the handpiece 10, and energy can be transmitted to skin tissue via the tip module 700.

[0037] Meanwhile, when energy is delivered by one shot through the handpiece, the treatment area is relatively small compared to the entire treatment area. Therefore, the medical team may perform several dozens of shots repeatedly during skin treatment. Therefore, the medical team often holds the handpiece 10 for a long time. In this case, if the handpiece 10 becomes considerably colder than the body temperature, the hand muscles of the medical team may become cold, making it difficult to use the handpiece properly, and if the handpiece 10 becomes too hot, it may also become difficult to use the handpiece properly. Therefore, the handpiece 10 according to the present disclosure is configured to maintain the temperature of the outer surface of the handpiece 10 held by the user at an appropriate level even when used for a long time.

[0038] FIG. 2 is an oblique view of a handpiece 10 for a treatment device according to one embodiment of the present disclosure, FIG. 3 is a partially exploded oblique view with the cover 200 and the chip module 700 in FIG. 2 removed, FIG. 4 is a cross-sectional view showing the refrigerant transfer space Vr and the energy transfer space Ve in a divided state, and FIG. 5 is an exploded oblique view of the handpiece 10 for a treatment device according to one embodiment of the present disclosure.

[0039] 2 to 5, in the present disclosure, the handpiece 10 can be configured to include a first housing 110, a second housing 120, a cover 200, a refrigerant tube, an insulating tube, an energy transfer element 300, a cap 600, and a chip module 700.

[0040] The handpiece 10 may be divided into an energy transfer space Ve, which serves as a path for transferring energy, and a refrigerant transfer space Vr, which serves to cool tissue.

[0041] The first housing 110 and the second housing 120 can be formed to extend in a predetermined length in the front-rear direction. The first housing 110 and the second housing 120 can be coupled to each other in the lateral direction and can define an energy transmission space Ve inside. An energy transmission element 300 can be provided inside the energy transmission space Ve. At least one of the energy transmission elements is a heat generating element 310 that can generate heat during the transmission of energy.

[0042] On the other hand, the second housing 120 can include a partition wall 121 formed to be recessed inward. The partition wall 121 can be formed to be recessed along the front-rear direction and in a size such that the outer surface of an insulating tube described later can be in close contact therewith.

[0043] By providing the partition wall 121 recessed in the second housing 120, the second housing 120 is formed asymmetrically with respect to the first housing 110.

[0044] The cover 200 can be configured to be coupled to the outside of the second housing 120. The cover 200 will define a refrigerant transmission space Vr together with the second housing 120. The rear end portion of the cover 200 can be coupled to the second housing 120 and can be additionally fixed by a fixing ring 123 so as to prevent detachment. However, such a fixing method is only an example, and various coupling methods that can fix the cover and maintain the refrigerant transmission space Vr can be applied.

[0045] On the one hand, the first housing 110, the second housing 120, and the cover 200 can be combined to form the outer surface of the handpiece. A part of the rear side of the handpiece 10 can be composed of a neck part 11 whose outer peripheral edge is smaller than that of the front side. The neck part 11 can be configured in a shape where the peripheral edge becomes larger as it goes forward. The user can grip the handpiece 10 at various positions according to the size of their hand. On the other hand, a user with small hands will especially grip the relatively small neck part 11 and use the handpiece 10 in this way.

[0046] On the outside of the second housing 120, a support wall 122 that extends laterally on the rear side can be provided. The support wall 122 can be configured to be in close contact with the rear end of the cover 200 laterally.

[0047] The refrigerant tube can be a passage through which the refrigerant received from the main body 2 moves to the chip module 700. The heat-insulating tube is provided to cover the refrigerant tube. A part of the refrigerant tube and all of the heat-insulating tube can be provided within the refrigerant transmission space Vr.

[0048] The refrigerant tube is formed with a predetermined length, and the rear end can penetrate the rear connection part 520 and the support wall 122. The front end of the refrigerant tube 410 can be connected to the front connection part 510. A first insertion part 511 is provided behind the front connection part 510, and the front end of the refrigerant tube 410 can be inserted therein. A nozzle 513 can be provided in front of the front connection part 510. The front connection part 510 can be provided with a first end jaw part 512 whose outer diameter expands in the middle part.

[0049] The rear connection part 520 is provided with a second insertion part 521 that is open in the front-rear direction at the central part. A refrigerant tube can be sandwiched inside the second insertion part 521. On the outside of the rear connection part 520, a second end jaw part 522 formed with an expanded outer diameter can be provided. The front of the second end jaw part 522 is supported by the rear end of the heat insulation tube, and the rear is supported by the support wall 122.

[0050] The cap 600 is configured to be coupled in the front-rear direction to the front ends of the first housing 110, the second housing 120, and the cover 200. The cap 600 can be configured with a hole through which the front connection part 510 can penetrate, and at least one hole can be formed so that energy can be transmitted by an energy transmission element. Further, the cap 600 can be provided with an electrical connector that can be electrically connected to the chip module 700 facing forward.

[0051] The chip module 700 is configured to receive energy transmission from the energy transmission element inside the handpiece 10 and finally transmit energy to the skin tissue. For this purpose, at least a part of the front end of the chip module 700 can be brought into contact with the skin. The chip module 700 can be detachably coupled to the front end of the cap.

[0052] Hereinafter, with reference to FIGS. 6 to 10, the handpiece 10 for a treatment device according to the present disclosure will be described from the perspective of internal thermal energy.

[0053] FIG. 6 is a side view showing the refrigerant tube 410 and the heat insulation tube 420 disassembled in the present disclosure, and FIG. 7 is a cross-sectional view showing the refrigerant tube 410 and the heat insulation tube 420 cut open in the present disclosure.

[0054] Referring to FIGS. 6 and 7, in the present disclosure, the refrigerant transmission space Vr can be provided with the refrigerant tube 410, the heat insulation tube 420, a part of the front connection part 510, and a part of the rear connection part 520.

[0055] As described above, the refrigerant tube 410 has its front end and rear end inserted into the front connection part 510 and the rear connection part 520 respectively. A heat insulation tube 420 is provided outside the refrigerant tube 410, and both side ends are supported by the first end jaw part 512 and the second end jaw part 522. Also, the inside of the heat insulation tube 420 is supported by the outside of the first insertion part 511 and the second insertion part 521.

[0056] At this time, a certain interval is formed between the outer surface of the refrigerant tube 410 and the inner surface of the heat insulation tube 420, and this interval becomes the first air gap G1. The first air gap G1 becomes a heat insulation layer by the thermal conductivity of the air itself.

[0057] Therefore, when the refrigerant is filled in the refrigerant tube 410, it is maintained at a low temperature, and the transfer rate of the thermal energy transferred to the refrigerant through the heat insulation tube 420 and the refrigerant tube 410 in the temperature transfer space is slowed down.

[0058] Figure 8 is a cross-sectional view taken along the line I-I' in Figure 2.

[0059] Referring to Figure 8, as described above, the second housing 120 is provided with a partition wall 121 formed by being recessed in the refrigerant transfer space Vr. At a position adjacent to the partition wall 121, a refrigerant tube 410 and a heating element 310 that generates thermal energy among the energy transfer elements can be provided.

[0060] Inside the refrigerant transfer space Vr, the refrigerant tube 410 can be heat-insulated in a double or more manner. As described above, the heat insulation tube 420 first heat-insulates the refrigerant tube 410.

[0061] A part of the outer surface of the heat insulation tube 420 is in close contact with the partition wall 121. The other part of the outer surface of the heat insulation tube 420 is in contact with a rib 210 formed with a predetermined size on the inner surface of the cover 200.

[0062] The rib 210 is formed to extend toward the refrigerant tube 410 inside the cover 200, and at least one rib can be provided. The rib 210 is configured to prevent the inner surface of the cover 200 from coming into direct contact with the heat insulation tube 420 and to fix the positions of the heat insulation tube 420 and the refrigerant tube 410. Each rib 210 can support the outer surface of the heat insulation tube 420 at different positions, and the respective ribs 210 can be provided at a predetermined interval from each other. Therefore, a second air gap G2 can be formed between the outer surface of the heat insulation tube 420 and the inner surface of the cover 200 within the refrigerant transmission space Vr.

[0063] In particular, the first air gap and the second air gap can be provided inside the neck portion where the user grips the handpiece.

[0064] As described above, even when the refrigerant tube 410 is filled with the refrigerant, since the refrigerant transmission space Vr is formed with a double heat insulation structure, the heat transfer by convection and the heat transfer by conduction are configured to alternate with each other, and the heat transfer efficiency can be lowered. Therefore, even when the refrigerant is filled in or moves through the refrigerant tube 410, the user holding the handpiece 10 does not feel cold.

[0065] FIG. 9 is a conceptual diagram showing the direction of the thermal energy moving to the refrigerant tube 410 in FIG. 8.

[0066] Referring to FIG. 9, since the temperature of the refrigerant is lower than the surroundings, the energy is transmitted to the refrigerant through the second air gap G2, the heat insulation tube 420, the first air gap G1, and the refrigerant tube 410 within the energy transmission space Ve. As described above, since the refrigerant tube 410 is doubly insulated with respect to the cover 200, the thermal energy moving from the outside through the cover 200 corresponds to only a very small part. Therefore, even when the medical team holds the handpiece 10 by hand, the amount of thermal energy taken away is extremely small and the temperature does not drop.

[0067] FIG. 10 is a conceptual diagram showing the direction in which the thermal energy generated by the heating element 310 in FIG. 8 moves to the refrigerant transmission space Vr.

[0068] Referring to FIG. 10, in the present disclosure, the thermal energy generated by the heating element 310 in the energy transmission space Ve moves to the refrigerant transmission space Vr through the separation wall 121. At this time, the thermal energy can be transmitted to the second air gap G2 and the heat insulating tube 420.

[0069] As described above, when the refrigerant fills the refrigerant tube 410, the thermal energy in the refrigerant transmission space Vr is continuously transmitted to the refrigerant with a low temperature, and the temperature of the second air gap G2 also becomes low. However, while the thermal energy discarded by the heating element 310 additionally moves to the refrigerant transmission space Vr through the separation wall 121, the temperature of the lowered second air gap G2 can be restored to a certain level.

[0070] Therefore, even when the handpiece 10 is operated, the refrigerant transmission space Vr maintains a certain temperature, so that when the user uses the handpiece 10, it can be used for a long time without a large temperature change. In addition, since the heating element 310 inside the handpiece 10 can also be easily cooled, the handpiece 10 can be stably used.

[0071] FIG. 11 is a diagram showing various forms of chip modules 700 detachable from the handpiece 10 for a treatment device according to the present disclosure.

[0072] Referring to FIG. 11, the chip module 700 applied to the handpiece 10 according to the present disclosure can be variously configured according to its purpose. In addition, the chip module 700 is detachably configured on the cap, and any one of the chip modules 700 can be selected and attached to the handpiece 10 for use.

[0073] As described above, the handpiece for a treatment device according to the present disclosure spatially separates the refrigerant transmission space and the energy transmission space, and maintains the temperature of the outer surface of the handpiece constant so that the user does not feel discomfort. Further, since it is possible to prevent a temperature rise due to heat generation inside, the safety of the handpiece can be improved.
