Description

Technical Field

[0001] The utility model relates to the technical field of microwaves, and in particular to a microwave treatment handle and a microwave treatment device. Background Art

[0002] Hyperhidrosis, or excessive sweating, is a common condition that can cause excessive sweating in the armpits, face, or feet. Sweating can lead to physical side effects, including dehydration and infection, as well as emotional side effects, such as embarrassment. Currently, multiple treatments for hyperhidrosis are known, including medications, antiperspirants, botulinum toxin, and microwave ablation.

[0003] An invention patent with application number "200880020760.1" and name "System for applying microwave energy to tissue and system for producing tissue effects in tissue layers" discloses a system for applying microwave energy to tissue, including a signal generator suitable for generating a microwave signal with predetermined characteristics, a radiator connected to the signal generator and suitable for applying microwave energy to the tissue, the radiator including one or more microwave antennas and a tissue interface, wherein the microwave antenna includes an antenna constructed to radiate electromagnetic radiation, and the electromagnetic radiation is polarized so that the electric field component of the electromagnetic radiation is substantially parallel to the outer surface of the tissue; a vacuum source connected to the tissue interface; a cooling source connected to the tissue interface; and a controller suitable for controlling the signal generator, the vacuum source, and the cooling source, wherein the radiator includes a cooling plate and a tissue chamber, the tissue chamber includes a tissue wall and the tissue interface, and a skin surface is combined in the tissue chamber so that the skin surface is in contact with at least a portion of the tissue wall and the cooling plate.

[0004] In this invention patent, the tissue interface module is equivalent to the microwave treatment head, the applicator is equivalent to the microwave treatment handle, and the waveguide antenna assembly in the microwave treatment handle is cooled by setting a cooling cavity on the periphery, and a coolant is provided in the cooling cavity. The cooling cavity is connected to the cooling source through a cooling tube to circulate the coolant to cool the waveguide antenna. This method requires setting a cooling tube in the microwave treatment handle, and connecting an external cooling device through the cooling tube to achieve the circulation of the coolant to cool the waveguide antenna. This increases the structural complexity and design and manufacturing costs of the tissue interface module.

[0005] In addition, when the tissue interface module is connected to the applicator for use, the proximal sealing component of the applicator chamber needs to be sealed with the applicator so that the applicator chamber, the tissue acquisition chamber and the airflow path are all in a negative pressure balance state. That is to say, basically most of the space within the tissue interface module needs to be in a negative pressure state, which places extremely high demands on the sealing design and sealing conditions of the internal structure of the tissue interface module, and will also increase the structural complexity and design and manufacturing costs of the tissue interface module.

[0026] The following will disclose multiple embodiments of the present invention with drawings.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model discloses a microwave treatment handle, including a housing 1 and a waveguide antenna assembly 2 . The housing 1 is provided with a mounting cavity 10 , and the waveguide antenna assembly 2 is disposed in the mounting cavity 10 .

[0029] The waveguide antenna assembly 2 includes an antenna bracket 21 and a plurality of waveguide antennas 22 arranged side by side. The antenna bracket 21 is provided with a storage groove 211. The waveguide antenna 22 is arranged in the storage groove 211. The antenna bracket 21 is also provided with a cooling chamber 212. The cooling chamber 212 surrounds the four sides and the bottom of the storage groove 211 and wraps the outside of the storage groove 211 as a whole. The cooling chamber 212 is a sealed cavity. Therefore, after the cooling chamber 212 is filled with coolant, the coolant is completely confined in the cooling chamber 212, and no new coolant enters the cooling chamber 212, forming a coolant circulation. The cooling chamber 212 is filled with coolant, so that the coolant can be wrapped around the waveguide antenna 22 to facilitate the cooling of the waveguide antenna 22.

[0030] At least a portion of the side wall forming the cooling chamber 212 is provided as a heat conducting plate 213, and the heat conducting plate 213 is in contact with the coolant, which is conducive to effectively transferring the heat attached to the coolant to the heat conducting plate 213, and then quickly conducting the heat away through the heat conducting plate 213, which is conducive to quickly cooling the coolant and keeping the coolant temperature within a preset temperature range. A heat dissipation device 3 is also provided in the installation cavity 10, and the heat dissipation device 3 is located outside the cooling chamber 212, and is used to quickly dissipate the heat conducted to the heat conducting plate 213 to the outside.

[0031] The housing 1 includes a bottom shell 111 and an upper cover 112. The mounting cavity 10 is disposed in the bottom shell 111. The waveguide antenna assembly 2 and the heat dissipation device 3 are both disposed in the bottom shell 111. An opening is disposed at the top of the bottom shell 111, and the upper cover 112 is disposed on the opening.

[0032] The heat generated by the waveguide antenna 22 is first conducted to the coolant in the cooling chamber 212, and then quickly transferred to the heat sink 3 through the heat conduction plate 213 in contact with the coolant. The heat sink 3 continuously operates to quickly dissipate the heat conducted by the heat conduction plate 213 to the outside, thereby achieving the purpose of cooling the waveguide antenna 22.

[0033] The heat conducting plate 213 is located on a side close to the heat dissipation device 3, which is conducive to the conduction of heat. A receiving port 14 is provided on the side wall between the receiving slot 211 and the cooling chamber 212, and the heat conducting plate 213 is arranged on the receiving port 14. The heat dissipation device 3 includes a heat dissipation plate 31 attached to the heat conducting plate 213 and a fan 32 arranged on the heat dissipation plate 31. The shape of the heat dissipation plate 31 is extended from the bottom end of the housing 1 to the top end of the housing 1. The heat conducting plate 213 is attached to the heat dissipation plate 31, which is conducive to the rapid conduction of the heat of the heat conducting plate 213 to the heat dissipation plate 31, and can improve the heat conduction efficiency of the heat dissipation plate 31. The heat on the heat dissipation plate 31 can realize heat convection through the fan 32, thereby accelerating the dissipation of heat.

[0034] An air inlet 11 is provided on the side wall of the housing 1 at a position directly facing the fan 32, and an air outlet 12 is provided on the side wall of the housing 1 at one end away from the storage slot 211. The air inlet direction of the air inlet 11 is perpendicular to the air outlet direction of the air outlet 12. The fan 32 is a centrifugal fan, and air can be sucked in through the air inlet 11 on the side of the handle, that is, the axial suction of the centrifugal fan, and form hot air after thermal convection with the heat sink 31 and the radiator 33. The hot air is then thrown out from the air outlet 12 on the top of the handle, that is, the radial throwing of the centrifugal fan, to ensure that the hot air coming out of the air outlet 12 is as far away as possible from the tissues around the treatment area, so as to avoid the possibility of the hot air from the air outlet 12 contacting the tissues around the treatment area during the operation of the handle.

[0035] A heat sink 33 is provided on the heat sink 31 near the air outlet 12, and the heat sink 33 is provided with a plurality of heat sinks spaced apart and arranged side by side. A heat pipe 13 is provided on one side of the heat sink 31 near the heat conducting plate 213, and the heat pipe 13 extends along the length direction of the heat sink 31. The heat sink 33 can increase the convection area with the hot air, which is conducive to the rapid dissipation of the heat of the hot air and improves the heat dissipation efficiency of the heat sink 3.

[0036] The bottom end of the storage groove 211 is connected to the cooling chamber 212, and the energy emitting end of the waveguide antenna 22 is immersed in the coolant, which is conducive to the full contact between the energy emitting end of the waveguide antenna 22 and the coolant, so that the heat of the energy emitting end can be fully and effectively transferred to the coolant. A ceramic plate 19 is provided at the bottom of the cooling chamber 212, and the ceramic plate 19 is in contact with the end face of the energy emitting end of the waveguide antenna 22. The ceramic plate 19 is conducive to the energy conduction of the energy emitting end of the waveguide antenna 22 and can seal the bottom of the cooling chamber 212.

[0037] Combination Figure 3and Figure 4 As shown, the utility model further provides a microwave treatment device, comprising a microwave treatment head 100 and a microwave treatment handle 200 of any of the above solutions, wherein the microwave treatment head 100 and the microwave treatment handle 200 are detachably connected.

[0038] A mounting frame 15 is provided at one end of the mounting cavity 10 of the microwave treatment handle 200 near the microwave treatment head 100, and a mounting opening 16 is provided on the mounting frame 15. The waveguide antenna assembly 2 is arranged in the mounting opening 16, and the energy emitting end of the waveguide antenna assembly 2 extends out from the mounting opening 16. The microwave treatment head includes a shell 4, which is provided with a receiving chamber 41 and an adsorption chamber 42. The receiving chamber 41 and the adsorption chamber 42 are separated by a rigid film 43. The energy emitting end of the waveguide antenna assembly 2 is arranged in the receiving chamber 41 and is in contact with the rigid film 43.

[0039] A negative pressure pipe 5 for connecting to a vacuum source is provided in the installation cavity 10, and a negative pressure pipe joint 6 is provided on the installation frame 15. The negative pressure pipe 5 is connected to the negative pressure pipe joint 6, and the negative pressure pipe joint 6 is sealed and connected to the adsorption chamber 42. The adsorption chamber 42, the negative pressure pipe joint 6 and the negative pressure pipe 5 form a negative pressure airflow path. After the vacuum source is started, the air in the adsorption chamber 42 is evacuated through the negative pressure pipe 5, so that the adsorption chamber 42 forms a negative pressure, and the tissue in the treatment area is sucked into the adsorption chamber 42. This process does not require the formation of negative pressure in the receiving chamber 41.

[0040] Therefore, under the same condition of sucking the tissue into the adsorption chamber, it is not necessary to seal the receiving chamber 41 to keep the receiving chamber 41 in a negative pressure state. This greatly simplifies the sealing design requirements of the internal structure of the microwave therapy head 100 and reduces the sealing condition requirements, and reduces the structural complexity and design and manufacturing costs of the microwave therapy head 100.

[0041] The housing 1 includes a mounting portion 114 and a holding portion 113, the mounting portion 114 and the holding portion 113 are arranged at an angle, and the microwave therapy head 100 is connected to the mounting portion 114. The mounting cavity 10 includes a first mounting cavity 101 arranged in the holding portion 113 and a second mounting cavity 102 arranged in the mounting portion 114, and the waveguide antenna assembly 2 is arranged in the second mounting cavity 102. An aviation connector 7 is provided at one end of the holding portion 113 away from the mounting portion 114, and a negative pressure pipe 5 is passed through the first mounting cavity 101 and the second mounting cavity 102, and the two ends of the negative pressure pipe 5 are respectively connected to the aviation connector 7 and the negative pressure pipe connector 6.

[0042] The side wall of the shell 4 away from the adsorption chamber 42 is provided with a plurality of connectors 44 for connecting with the microwave treatment handle 200, the connectors 44 are provided with a first hook 45, and the outer side wall of the connector 44 is also provided with a button 46 protruding outward. The side of the shell 1 close to the microwave treatment head 100 is provided with a connecting groove 17 for receiving the connector 44, the connecting groove 17 is located on the outer side of the mounting frame 15, and the side wall of the connecting groove 17 is provided with a second hook 18 corresponding to the first hook 45.

[0043] By inserting the connector 44 into the connecting groove 17, the first hook 45 is correspondingly connected to the second hook 18, thereby realizing the quick connection between the microwave therapy head 100 and the microwave therapy handle 200. By pressing the button 46, the first hook 45 is separated from the second hook 18, thereby realizing the quick separation of the microwave therapy head 100 and the microwave therapy handle 200, thereby improving the speed of assembly and disassembly of the microwave therapy head 100 and the microwave therapy handle 200.

[0044] Compared with the prior art, the utility model has the following beneficial effects: the microwave treatment handle of the utility model is provided with a cooling chamber on the periphery of the storage slot, a coolant is provided in the cooling chamber, and the coolant is sealed in the cooling chamber, and a cooling device is provided on the outer shell to cool the coolant, thereby achieving the purpose of cooling the waveguide antenna assembly, and no cooling pipe is required to connect an external cooling source. The structural design requirements of the microwave treatment head are greatly simplified, and the structural complexity and design and manufacturing costs of the microwave treatment head are reduced.

[0045] Therefore, under the condition of cooling the waveguide antenna assembly, it is not necessary to seal the receiving chamber to keep it in a negative pressure state, thereby greatly simplifying the sealing design requirements of the internal structure of the microwave treatment handle, reducing the requirements for sealing conditions, and reducing the structural complexity and design and manufacturing costs of the microwave treatment handle.
