Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic therapy, and particularly relates to an ultrasonic therapy head with a sealed connection structure. Background Art

[0002] High-intensity focused ultrasound therapy technology can focus ultrasonic waves to form high-intensity and continuous ultrasonic energy on the lesion, thereby generating transient high-temperature effects, cavitation effects, mechanical effects, and sonochemical effects, causing the cell membrane and nuclear membrane to rupture, protein to coagulate, and selectively causing coagulative necrosis of the lesion tissue, so that the lesion loses the ability to proliferate, infiltrate, and metastasize.

[0003] During the treatment process of an ultrasonic therapy device, the ultrasonic therapy head needs to be placed in water. To facilitate the replacement of the ultrasonic therapy head, a connector connected to a cable needs to be provided on the ultrasonic therapy head and this connector needs to prevent water ingress. The waterproof structure of a traditional ultrasonic therapy head only uses an O-ring for sealing, and different treatment scenarios during use often require frequent replacement of the ultrasonic therapy head. Due to different dimensional deviations and wear conditions of the ultrasonic therapy head, it is difficult to ensure a consistent compression amount of the sealing ring, thus making it difficult to ensure the reliability of the seal. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an ultrasonic therapy head with a sealed connection structure, which is used to solve the problem of low sealing reliability at the assembly of the connector of the ultrasonic therapy head in the prior art.

[0005] To achieve the above purpose and other related purposes, the present invention provides an ultrasonic therapy head with a sealed connection structure, including a water receiving tray and a therapy head body provided on the water receiving tray. A female connector is installed at the bottom of the therapy head body, and a male connector mating with the female connector is installed on the water receiving tray. A sealing component and an elastic element are provided on the water receiving tray. The sealing component is located outside the male connector and the female connector, and the elastic element presses the sealing component against the bottom surface of the therapy head body. The sealing component seals the gap between the bottom surface of the therapy head body and the water receiving tray, forming a water isolation channel in the space inside the sealing component, and the male connector and the female connector are located in the water isolation channel.

[0006] The beneficial effect of the present invention is that the sealing component makes the male connector and the female connector in a sealed environment under the action of the elastic element, improving the sealing performance and ensuring the reliability of the waterproof seal. Moreover, the sealing component can be adjusted floatingly and has high versatility.

[0007] Optionally, the sealing component includes a sliding sealing sleeve and a first sealing ring installed on the upper end surface of the sliding sealing sleeve. The sliding sealing sleeve is sealed with the bottom surface of the therapy head body through the first sealing ring.

[0009] Optionally, a groove for installing the second sealing ring is provided on the inner wall of the mounting hole or on the outer wall of the sliding sealing sleeve in a circumferential manner.

[0010] Optionally, a stepped surface is provided in the mounting hole, and an upper limit portion is provided on the outer wall of the sliding sealing sleeve. The upper limit portion is used to abut against the stepped surface to limit the upward movement of the sliding sealing sleeve.

[0011] Optionally, the ultrasonic treatment head with the sealed connection structure further includes a fixed end cover connected to the water receiving tray. The fixed end cover is provided with a through hole for the lower end of the sliding sealing sleeve and the lower end of the male connector to pass through. A lower limit portion is provided on the outer wall of the sliding sealing sleeve. The lower limit portion is used to cooperate with the fixed end cover to limit the downward movement of the sliding sealing sleeve to disengage from the water receiving tray.

[0012] Optionally, the elastic element is a spring. The spring is located in the mounting hole, sleeved on the outside of the sliding sealing sleeve, and both ends of the spring respectively abut against the fixed end cover and the upper limit portion.

[0013] Optionally, the second sealing ring is located above the stepped surface of the mounting hole of the water receiving tray.

[0014] Optionally, a water retaining cylinder is installed on the water receiving tray. The water retaining cylinder and the water receiving tray cooperate to form a cavity capable of holding water. The treatment head body is located in this cavity, and the top of the treatment head body is lower than the top of the water retaining cylinder.

[0015] Optionally, a probe is installed on the water receiving tray. The probe extends from the bottom of the treatment head body into the inside of the treatment head body.

[0016] The beneficial effects of adopting the above optional solutions are as follows: The assembly position of the male connector and the female connector is in a sealed and waterproof space, and the sealed assembly is stable and reliable.

[0033] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0034] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear narration, rather than to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0035] As Figures 1 to 3 shown, the ultrasonic treatment head with a sealed connection structure of the present invention includes a water receiving tray 9 and a treatment head body 8 provided on the water receiving tray 9. A female connector 7 is installed at the bottom of the treatment head body 8, and a male connector 6 that cooperates with the female connector 7 is installed on the water receiving tray 9. A sealing component and an elastic element 4 are provided on the water receiving tray 9. The sealing component is located outside the male connector 6 and the female connector 7. The elastic element 4 presses the sealing component against the bottom surface of the treatment head body 8. The sealing component seals the gap between the bottom surface of the treatment head body 8 and the water receiving tray 9, so that the space inside the sealing component forms a water isolation channel, and the male connector 6 and the female connector 7 are located inside the water isolation channel, thereby ensuring the sealing performance when the treatment head body 8 and the water receiving tray 9 are assembled, preventing water from entering the inside of the male connector and the female connector, and being safer and more reliable.

[0036] As Figure 2 and Figure 3 shown, in an exemplary embodiment, a water isolation channel is axially penetrated through the sliding seal sleeve 1. A boss is provided inside the water isolation channel. The male connector 6 is fixedly assembled with the boss. The top of the male connector 6 is lower than the top of the sealing member, so that the male connector 6 is stably installed in the sliding seal sleeve 1.

[0037] As Figures 1 to 3 shown, in an exemplary embodiment, the sealing member includes a sliding seal sleeve 1 and a first sealing ring 2 installed on the upper end surface of the sliding seal sleeve 1. The sliding seal sleeve 1 and the bottom surface of the treatment head body 8 are sealed by the first sealing ring 2, and the sealing performance is stable and reliable.

[0038] As Figures 1 to 3 shown, in an exemplary embodiment, the water receiving tray 9 is provided with a mounting hole. The sliding seal sleeve 1 is installed in the mounting hole. A second sealing ring 3 is provided between the outer wall of the sliding seal sleeve 1 and the inner wall of the mounting hole. The sliding seal sleeve 1 and the water receiving tray 9 are sealed by the second sealing ring 3. Among them, a groove for installing the second sealing ring 3 is provided on the inner wall of the mounting hole in a ring shape, or a groove for installing the second sealing ring 3 is provided on the outer wall of the sliding seal sleeve 1 in a ring shape. The assembly is stable and the sealing performance is improved. In this embodiment, the groove for installing the second sealing ring 3 is provided on the inner wall of the mounting hole of the water receiving tray 9 in a ring shape.

[0039] As Figures 1 to 3 shown, in an exemplary embodiment, a step surface is provided in the mounting hole of the water receiving tray 9. An upper limit portion is convexly provided on the outer wall of the sliding seal sleeve 1. The upper limit portion is used to abut against the step surface to limit the upward movement of the sliding seal sleeve 1, so as to prevent the sliding seal sleeve 1 from moving upward and disengaging from the water receiving tray 9 under the action of the elastic element 4. In the initial state, the upper limit portion abuts against the step surface, the upper end surface of the sliding seal sleeve 1 is higher than the upper end surface of the water receiving tray 9, and the elastic element 4 is in a compressed state.

[0040] As Figures 1 to 3 shown, in an exemplary embodiment, the ultrasonic treatment head with a sealing connection structure further includes a fixed end cover 5 connected to the water receiving tray 9. The fixed end cover 5 is provided with a through hole for the lower end of the sliding seal sleeve 1 and the lower end of the male connector 6 to pass through. A lower limit portion is provided on the outer wall of the sliding seal sleeve 1. The lower limit portion is used to cooperate with the fixed end cover 5 to limit the downward movement of the sliding seal sleeve 1 and disengage from the water receiving tray 9. The lower limit portion can cooperate with and abut against the edge of the through hole of the fixed end cover 5 to limit the sliding seal sleeve from continuing to move downward.

[0041] As Figures 1 to 3 shown, in an exemplary embodiment, the elastic element 5 can be a spring. The spring is located in the mounting hole of the water receiving tray 9. The spring is sleeved on the outside of the sliding seal sleeve 1, and both ends of the spring respectively abut against the fixed end cover 5 and the upper limit portion.

[0042] As Figure 2 and Figure 3 shown, in an exemplary embodiment, the second sealing ring 3 is located above the inner step surface of the mounting hole of the water receiving tray 9. The step surface, the upper limiting portion, the lower limiting portion, and the fixed end cover are distributed in sequence from top to bottom. Adopting this local method, the layout is compact and occupies a small space, making the space below the second sealing ring a waterproof space, ensuring the dryness of the internal space, preventing the components from being easily corroded, and being safer and more reliable.

[0043] As Figure 1 and Figure 2 shown, in an exemplary embodiment, the male connector 6 can be an electrical connection socket. The lower end of the male connector 6 is stably connected to the cable for power supply. The female connector 7 can be an electrical connection plug. The plugging operation is simple and convenient, facilitating continuous and stable power supply for the device, and ensuring the water tightness of the power supply environment, thereby improving the safety performance.

[0044] As Figures 1 to 3 shown, in an exemplary embodiment, a water retaining cylinder 10 is installed on the water receiving tray 9. The water retaining cylinder 10 and the water receiving tray 9 cooperate to form a cavity capable of holding water. The bottom of the water retaining cylinder 10 is hermetically assembled with the water receiving tray 9 to prevent the water 12 in the water retaining cylinder 10 from leaking out accidentally. The treatment head body 8 is installed in the cavity with water 12. The water retaining cylinder 10 surrounds the periphery of the treatment head body 8, and the top of the water retaining cylinder 10 is higher than the top of the treatment head body 8. During ultrasonic treatment, the treatment head body 8 is immersed in the water environment of the water retaining cylinder 10.

[0045] As Figures 1 to 3 shown, in an exemplary embodiment, a probe 11 is installed on the water receiving tray 9. The bottom of the treatment head body 8 is provided with a channel for the probe 11 to extend into the inside of the treatment head body 8. In this embodiment, the probe 11 can be a B-ultrasound probe, which is convenient for observing the lesion and improving the effect of the ultrasonic treatment head. Both the probe 11 and the male connector 6 are located on the side of the water-free environment. The first sealing ring 2 and the second sealing ring 3 prevent the water in the water retaining cylinder 10 from entering the water-free environment side, improving the electrical safety.

[0046] Its working process is as follows: When the treatment head body is not installed, the sliding seal sleeve is pushed up under the action of the elastic element. When installing the treatment head body, the female connector at the bottom of the treatment head body is inserted into the male connector in the sliding seal sleeve, and at the same time, the sliding seal sleeve is pressed down until the treatment head body reaches the fixed position. At this time, the elastic element is in a compressed state, and the first sealing ring is closely attached to the bottom surface of the treatment head body under the elastic force of the elastic element, thereby forming a stable seal between the bottom surface of the treatment head body and the top surface of the sliding seal sleeve.

[0047] The ultrasonic treatment head with a sealed connection structure of the present invention drives the sealing component to float and adjust through an elastic element, so that the sealing component can be fully sealed with the bottom surface of the treatment head body, avoiding the inability to ensure the sealing performance due to dimensional deviation when replacing the treatment head body, having stronger versatility, improving the sealing of the water-free environment inside the device, and making the device safer and more reliable.

[0048] The above embodiments merely illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
