Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an ultrasonic therapy head and an ultrasonic therapy device. Background Technology

[0002] Existing focused ultrasound treatment heads typically require a conductive fluid (such as water) as a medium to transmit the ultrasonic energy generated by the transducer. The conductive fluid, as a medium, needs to be sealed inside a sealed chamber. During treatment, due to the vibration of ultrasonic waves, bubbles will form inside the sealed chamber. Over time, small bubbles will aggregate and merge to form large bubbles. If the position of the large bubble moves into the ultrasonic energy transmission path, it will cause energy abnormalities, affect the treatment effect, and may even damage the transducer.

[0003] Some focused ultrasound treatment heads in related technologies have a bubble collection space within a sealed chamber to collect the bubbles. However, the collection space is an open structure and is connected to the sealed chamber, resulting in poor bubble restraint. When the angle of use of the focused ultrasound treatment head changes, the bubbles can easily escape from the collection space and move into the ultrasound energy transmission path, thus affecting the treatment effect and even damaging the transducer.

[0004] Therefore, there is an urgent need to research an ultrasonic treatment head and ultrasonic treatment device to solve the above problems. Utility Model Content

[0014] As an optional technical solution for an ultrasonic treatment head, the ultrasonic treatment head further includes a partition that divides the internal space of the outer shell into a first chamber and a second chamber, and the connecting channel is formed on the partition.

[0015] As an optional technical solution for an ultrasonic treatment head, the baffle member includes a bubble guiding structure on the side facing the first chamber. The bubble guiding structure is a funnel shape with a gradually increasing cross-section, and the connecting channel is located at the narrowest point of the funnel opening; or,

[0019] As an optional technical solution for an ultrasonic treatment head, the outer shell has an installation channel, the sealing body is disposed in the installation channel, and the sealing body can move along the extension direction of the installation channel under external force to switch between an open state and a closed state.

[0020] As an optional technical solution for an ultrasonic treatment head, when the outer shell is not assembled with the handle, a portion of the occluder is located outside the outer shell and is in an open state; when the outer shell is assembled with the handle, the handle pushes the occluder to move and maintain it in the closed state.

[0021] As an optional technical solution for an ultrasonic treatment head, the occluder has a guide bevel along the assembly direction from which the outer shell is assembled to the handle.

[0040] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0041] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides an ultrasonic therapy head, which includes a housing 100, a baffle 200, a transducer 300, and a blocking assembly 400. The internal space of the housing 100 includes a first chamber 110 and a second chamber 120. The first chamber 110 contains an acoustically transparent medium, and the second chamber 120 is used to store air bubbles. The first chamber 110 and the second chamber 120 are connected by a connecting channel 210. The transducer 300 is disposed inside the first chamber 110, and the second chamber 120 is located outside the transmission path of the ultrasonic waves emitted by the transducer 300. The blocking assembly 400 is disposed at the connecting channel 210 and includes a blocking body 410. The blocking body 410 can switch between an open state and a closed state to open or close the connecting channel 210. Before use, the second chamber 120 is positioned above the first chamber 110 by properly positioning the ultrasonic treatment head at an angle. The air bubbles in the first chamber 110 will automatically rise and enter the second chamber 120 through the connecting channel 210. Then, the sealing body 410 is moved to the closed state to block the connecting channel 210. No matter what position the ultrasonic treatment head is in during use, the air bubbles in the second chamber 120 cannot escape, preventing the air bubbles from moving into the ultrasonic energy transmission path, thus ensuring the treatment effect and the safety of the transducer 300.

[0045] When the sealing body 410 is in the closed state, the sealing body 410 is inserted into and seals the connecting channel 210; when the sealing body 410 is in the open state, the sealing body 410 is located outside the connecting channel 210. By inserting the sealing body 410 into the connecting channel 210, the sealing effect of the connecting channel 210 is reliable.

[0046] To further improve the sealing effect and facilitate the insertion of the sealing body 410, reducing the dimensional accuracy requirements for the sealing body 410 and the connecting channel 210, in the first embodiment of this example, the diameter of the connecting channel 210 gradually increases along the direction away from the first chamber 110, and the diameter of the sealing body 410 is greater than the minimum diameter of the connecting channel 210 and less than the maximum diameter of the connecting channel 210. In the second embodiment of this example, the diameter of the sealing body 410 gradually decreases along the direction closer to the first chamber 110, and the diameter of the connecting channel 210 is greater than the minimum diameter of the sealing body 410 and less than the maximum diameter of the sealing body 410. In the third embodiment of this example, the diameter of the connecting channel 210 gradually increases along the direction away from the first chamber 110, and the diameter of the sealing body 410 gradually decreases along the direction closer to the first chamber 110, and the maximum diameter of the connecting channel 210 is greater than the minimum diameter of the sealing body 410, and the minimum diameter of the connecting channel 210 is less than the maximum diameter of the sealing body 410.

[0047] The ultrasonic treatment head also includes a partition 200, which divides the internal space of the outer shell 100 into a first chamber 110 and a second chamber 120, with a connecting channel 210 formed on the partition 200. In this embodiment, the partition 200 is extended and the connecting channel 210 is disposed on the partition 200; this facilitates the processing of the connecting channel 210 and the control of its shape and processing precision. Simultaneously, the connecting channel 210 can be sealed through the cooperation of the sealing body 410 and the partition 200, facilitating the assembly of the sealing body 410. In other embodiments, the connecting channel 210 can be formed by the partition 200 and the outer shell 100. In other embodiments, the first chamber 110 and the second chamber 120 can be formed internally through a localized recess in the outer shell 100 itself.

[0048] The baffle 200, facing the first chamber 110, includes a bubble guiding structure 220. The bubble guiding structure 220 is a funnel-shaped structure with a gradually increasing cross-section, and the connecting channel 210 is located at the narrowest point of the funnel. The bubble guiding structure 220 facilitates the smooth entry of bubbles into the second chamber 120.

[0049] Specifically, in one embodiment, the partition 200 is generally a curved panel structure, and its lower surface forms a flared opening. In another embodiment, the partition 200 has different thicknesses at different locations, its upper surface is flat, and its lower surface has an arc-shaped structure forming a flared opening.

[0050] In some embodiments, the cross-sectional area of ​​the first chamber 110 near the partition 200 gradually decreases, and the connecting channel 210 is located at the narrowest point of the cross-sectional area of ​​the first chamber 110 near the partition 200. In other words, the partition is a flat plate structure and is arranged at an angle so that the cross-sectional area of ​​the first chamber 110 near the partition 200 gradually decreases. Alternatively, the partition is a plate-like structure, and part of it is arranged at an angle so that the cross-sectional area of ​​the first chamber 110 near the partition 200 gradually decreases. The partition is located above or diagonally above the first chamber 110, which also allows the bubbles to be gathered and smoothly enter the second chamber 120, improving operational convenience and efficiency.

[0051] In some embodiments, at least one of the partition 200 and the sealing body 410 is an elastic member, so that when the sealing body 410 is inserted into the communication channel 210, the sealing effect is better. For example, the partition 200 is made of rubber. For another example, the sealing body 410 is made of rubber. For yet another example, both the partition 200 and the sealing body 410 are made of rubber.

[0052] Furthermore, the sealing assembly 400 also includes a sealing ring 430, which is sleeved on the outer periphery of the sealing body 410 or embedded in an annular groove formed in the inner wall of the communicating channel 210. The sealing ring 430 helps to further improve the sealing effect of the sealing body 410 on the communicating channel 210. The sealing ring 430 is made of rubber. In embodiments where the sealing ring 430 is made of rubber, the sealing body 410 and the partition 200 can be made of materials that do not undergo elastic deformation, such as plastic or metal.

[0053] In some embodiments, the housing 100 has an installation channel, the occluder 410 is disposed in the installation channel, and the occluder 410 can be moved along the extension direction of the installation channel by an external force to switch between an open state and a closed state. The installation channel in the above configuration constrains the movement path of the occluder 410, ensuring its movement trajectory; and helps to reduce the overall size of the ultrasonic treatment head in the axial direction of the occluder 410.

[0054] When the outer shell 100 is not assembled with the handle 500, part of the occluder 410 is located outside the outer shell 100 and is in an open state. When the outer shell 100 is assembled with the handle 500, the handle 500 pushes the occluder 410 to move and keeps it in a closed state. The association between the handle 500 and the occluder 410 reduces the steps of operating the occluder 410 separately and shortens the preparation time before surgery. When the handle 500 and the outer shell 100 are engaged, the occluder 410 remains in a closed state, ensuring that air bubbles do not escape during the use of the ultrasonic treatment head.

[0055] For example, the sealing body 410 has a guide slope 411. Along the assembly direction from which the housing 100 is assembled to the handle 500, the guide slope 411 is inclined towards the first chamber 110. The assembly direction forms an angle with the direction in which the sealing body 410 moves from the open state to the closed state. This arrangement adapts to the assembly direction of the handle 500, ensuring that the sealing body 410 is closed during the assembly of the housing 100 to the handle 500, thus improving operational efficiency. The assembly direction is... Figure 1 The direction of the hollow arrow in the middle.

[0056] In some embodiments, the sealing assembly 400 includes a seal 420 that is sealingly connected between the sealing body 410 and the housing 100 to seal the gap between the sealing body 410 and the sidewall of the mounting channel. The seal 420 effectively prevents air bubbles from escaping and also prevents leakage of the sound-transmitting medium.

[0057] The seal 420 is an annular structure and is located within the installation channel. The outer ring of the seal 420 is connected to the side wall of the installation channel, and the inner ring of the seal 420 is connected to the sealing body 410. This reduces the space occupied by the seal and helps to reduce the overall volume of the outer shell 100, thereby miniaturizing the ultrasonic treatment head.

[0058] The sealing element 420 is made of an elastic material. The sealing element 420 applies an elastic force to the occluding body 410, ensuring that the occluding body 410 always tends to move towards the open state. This configuration allows the sealing element 420 to provide both sealing and elasticity, supplying the occluding body 410 with elastic force, enabling it to move to the open state. This reduces the number of parts and eliminates the need for separate operation. After the outer shell 100 separates from the handle 500, the occluding body 410 automatically moves to the open state, facilitating the rapid transfer of air bubbles generated in the first chamber 110 during the previous surgery to the second chamber 120 before subsequent procedures. This simplifies the structure and operational process, improving surgical efficiency.

[0059] In other embodiments, an elastic element may be provided separately to provide elastic force to the sealing body 410 so that it always has a tendency to move to the open state.

[0060] This embodiment also provides an ultrasonic therapy device, including a handle 500 and an ultrasonic therapy head as described in any of the above embodiments. When the handle 500 is connected to the ultrasonic therapy head, the sealing body 410 remains in a closed state. The handle 500 is connected to the housing 100 via a built-in slide rail. The slide rail consists of a guide rail fixed to the housing 100 and a slider at the bottom of the handle 500, allowing the housing 100 to slide along the assembly direction and locking it with a spring clip.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
