Description

Technical Field

[0001] This utility model relates to the field of thermotherapy generator technology, specifically a radio frequency thermotherapy generator housing with a heat dissipation structure. Background Technology

[0002] A radiofrequency hyperthermia generator is a medical device that uses radiofrequency electromagnetic waves to act on human tissue, causing charged particles to move and generate heat through friction, thereby producing controllable local high temperatures at the tumor or lesion site. It consists of a radiofrequency source, power control, temperature monitoring and cooling system, etc. It can precisely adjust the hyperthermia temperature and is often used in conjunction with image-guided technology to treat deep tumors or enhance the effects of radiotherapy and chemotherapy, while reducing damage to normal tissues.

[0003] Upon investigation, a Chinese utility model patent discloses a tumor hyperthermia device (publication number: CN213666070U), which includes a hyperthermia bed, a hyperthermia cover, and a lead screw and slider mechanism. The lead screw and slider mechanism includes a lead screw and a slider. The lead screw is located on the side of the hyperthermia bed and is rotatably connected to the hyperthermia bed. The slider is fixedly connected to the hyperthermia cover.

[0004] In the aforementioned patent, the position of the sliding pillow on the backrest can be adjusted by rotating the knob, allowing medical staff to adjust it according to the different needs of the patients, thus improving the applicability of the device. However, no heat dissipation measures are provided on the heat therapy cover, and the heat generated by the radiofrequency heat therapy generator during operation cannot be dissipated in time, which may lead to a decrease in the performance of the radiofrequency heat therapy generator, thereby affecting the safety and stability of the treatment.

[0005] Therefore, this utility model provides a radio frequency hyperthermia generator housing with a heat dissipation structure to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a radiofrequency hyperthermia generator housing with a heat dissipation structure, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a main body 1, a mounting plate 2 on one side of the main body 1, a first heat sink 4 fixedly connected to the side of the mounting plate 2 near the main body 1, a pin 8 fixedly connected to the first heat sink 4, a second heat sink 5 on the top of the first heat sink 4, the inner wall of the second heat sink 5 fitting against the outer wall of the first heat sink 4, the pin 8 inserted into the interior of the second heat sink 5, pipe grooves 6 formed on both the outer wall of the first heat sink 4 and the inner wall of the second heat sink 5, copper pipes 7 fixedly connected inside the pipe grooves 6, a first slot 3 formed inside the main body 1, both the first heat sink 4 and the second heat sink 5 inserted into the first slot 3, and flow grooves 12 formed on both the main body 1 and the mounting plate 2.

[0026] The bottom of the outer shell 1 is provided with a connecting groove, and a connecting pipe 9 is provided inside the connecting groove. The top end of the connecting pipe 9 is screwed into the inside of the copper pipe 7. A cylinder 10 is fixedly connected to the side surface of the connecting pipe 9. Several evenly distributed anti-slip grooves are provided on the side surface of the cylinder 10. A rubber pad 11 is fitted on the side surface of the connecting pipe 9. The top of the rubber pad 11 is in contact with the top inner wall of the connecting groove, and the bottom of the rubber pad 11 is in contact with the top of the cylinder 10.

[0027] During assembly, the first heat sink 4 and the second heat sink 5 need to be inserted into the first slot 3. Both ends of the copper tube 7 have internal threads. After the mounting plate 2 comes into contact with the main body 1 of the casing, the connecting tube 9 can be removed and screwed onto both ends of the copper tube 7. The anti-slip groove increases the friction between the cylinder 10 and the hand, reducing the possibility of slippage during the installation of the connecting tube 9. The bottom end of the connecting tube 9 also has threads for connecting an external cooling circulation device. The casing needs to be installed on a treatment bed during use. The radiofrequency thermotherapy generator needs to be installed on the inner wall of the main body 1 of the casing. The radiofrequency thermotherapy generator generates heat during operation. Heat is transferred through the outer casing 1 to the first heat sink 4 and the second heat sink 5. When the external cooling circulation device is running, the coolant flows into the copper pipe 7. As the coolant flows inside the copper pipe 7, it carries away the heat from the first heat sink 4 and the second heat sink 5, thus achieving a heat dissipation effect. This reduces the possibility of damage to the radiofrequency hyperthermia generator due to excessive temperature and improves the service life of the radiofrequency hyperthermia generator. In addition, the opening of the circulation groove 12 is for air circulation. When the air flows through the circulation groove 12, it can also carry away the heat from the first heat sink 4 and the second heat sink 5, effectively improving the heat dissipation efficiency.

[0028] Furthermore, in order to improve the stability of the first heat sink 4 and the second heat sink 5, such as... Figure 2 , Figure 4 and Figure 5As shown, a mounting shell 14 is fixedly connected to the outer shell body 1. A connecting rod 15 is movably connected inside the mounting shell 14. One end of the connecting rod 15 is fixedly connected to an insert block 16, and the other end of the connecting rod 15 extends to the outside of the mounting shell 14 and is rotatably connected to an adjusting handle 18.

[0029] The outer casing 1 has a second slot 13. The bottom of the mounting plate 2 is fixedly connected to a connecting block 21. The connecting block 21 is inserted into the second slot 13. One side of the connecting block 21 has a socket that matches the plug 16. The end of the plug 16 away from the connecting rod 15 extends into the second slot 13 and is inserted into the socket.

[0030] A spring 17 is fitted on the side surface of the connecting rod 15. One end of the spring 17 is fixedly connected to the inner wall of the mounting housing 14, and the other end of the spring 17 is fixedly connected to the end of the insert block 16 near the connecting rod 15.

[0031] After the first heat sink 4 and the second heat sink 5 are fully inserted into the first slot 3, the connecting block 21 will also enter the second slot 13, and the insertion hole will be aligned with the insertion block 16. At this time, the adjusting handle 18 can be turned so that the connecting rod 15 drives the insertion block 16 to be inserted into the insertion hole, thereby limiting the position of the mounting plate 2 and improving the stability of the first heat sink 4 and the second heat sink 5.

[0032] Furthermore, in order to reduce the frictional force of the movement of the first heat sink 4, such as Figure 1 , Figure 2 and Figure 3 As shown, an auxiliary groove 19 is provided inside the main body 1 of the outer shell. A rotating shaft is fixedly connected inside the auxiliary groove 19. A roller 20 is rotatably connected to the side surface of the rotating shaft. The side surface of the roller 20 is in contact with the bottom of the first heat sink 4.

[0033] During the movement of the first heat sink 4 inside the first slot 3, its bottom will come into contact with the roller 20. Due to the influence of friction, the roller 20 will rotate on the shaft, thereby assisting the movement of the first heat sink 4, effectively reducing the friction of the movement of the first heat sink 4, and improving the smoothness of the movement of the first heat sink 4.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
