Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasonic medical device. Background Technology
[0002] Focused ultrasound therapy is an advanced medical technology. The ultrasound medical device consists of two main parts: a treatment head and a handpiece housing. The treatment head contains an ultrasound device, which is applied to the treatment area by holding the handpiece, thus achieving precise treatment of diseased tissue.
[0003] In related technologies, a heat sink is installed in the handle housing to reduce the temperature of the treatment head. However, a problem exists where the heat-conducting end of the heat sink cannot properly contact the treatment head. Specifically, the handle housing and treatment head are directly connected via detachable methods such as snap-fit or magnetic attraction. Therefore, for ultrasound medical devices, the parts that directly contact the handle housing and treatment head are these mechanical connectors. The heat-conducting end of the heat sink does not directly contribute to the fixed connection between the treatment head and the handle, and its connection is less secure than that of directly contacting mechanical connectors. Consequently, there is insufficient contact between the heat-conducting end of the heat sink and the contact end of the treatment head, thus affecting the heat dissipation effect. This poor contact reduces the efficiency of the heat sink, causing the treatment head to overheat during prolonged operation, potentially affecting the treatment effect and the safety and stability of the device.

[0033] Please see Figure 1 and Figure 2 The ultrasonic medical device proposed in this utility model includes:
[0034] The treatment head 10 includes a housing 11 and an end cap 12. The end cap 12 is connected to the housing 11 and encloses to form a first receiving cavity 10a. An ultrasonic transducer 13 is provided in the first receiving cavity 10a. The housing 11 is provided with a treatment end 11a. The end cap 12 is provided with a connecting end 12a at the end away from the treatment end 11a.
[0035] The handle housing 20 is connected to the connecting end 12a; the handle housing 20 encloses a second receiving cavity 20a, and a heat sink 30 is provided inside the second receiving cavity 20a. A heat-conducting end 30a is provided on the side of the heat sink 30 facing the connecting end; and
[0036] The elastic component 40 is disposed in the second receiving cavity 20a and connected to the heat sink 30 so that the heat-conducting end abuts against the connecting end 12a.
[0037] In the technical solution of this utility model, the ultrasonic medical device includes a treatment head 10, a handle housing 20, and an elastic component 40. The treatment head 10 is provided with an ultrasonic transducer 13. The elastic component 40 is located in the handle housing 20. The elastic component 40 can provide a spring force to the heat sink 30 towards the connecting end 12a. In this way, under the action of the spring force, the heat-conducting end 30a can always press against the connecting end 12a of the end cap 12, so that the heat generated by the ultrasonic transducer 13 during operation can be directly absorbed by the heat-conducting end 30a of the heat sink 30, thereby improving the heat dissipation effect of the treatment head 10 and ensuring the treatment effect and safety and stability of the ultrasonic medical device.
[0038] To explain this technical solution, we first propose a directional concept to explain the following content: Please refer to... Figure 1 In the text, all references to "horizontal", "length direction" and "axial direction" refer to the Y-axis direction, while all references to "vertical" and "up and down" refer to the Z-axis direction.
[0039] The treatment head 10 is equipped with an ultrasonic transducer 13, which converts electrical energy into high-frequency sound wave energy and uses lenses and mirrors to focus the sound beam at the focal point to generate powerful energy, thereby achieving the purpose of focused ultrasound therapy. A thermally conductive silicone sheet is provided on the side of the end cap 12 facing the handle housing 20, so that the side of the thermally conductive silicone sheet facing the handle housing 20 forms a contact surface. The treatment head 10 and the handle housing 20 are connected to the handle housing 20 by snap-fit, plug-in or other means, and can be further sealed and reinforced with adhesive.
[0040] The handle housing 20 is composed of two half-shells, which are assembled to form a second receiving cavity 20a. The second receiving cavity 20a extends along the axial direction (i.e., the length direction) of the handle housing 20 to the end near the treatment head 10. The second receiving cavity 20a contains a control circuit, a circuit board, and a heat sink 30. The heat sink 30 is configured to fit the shape of the second receiving cavity 20a, and its heat-conducting end 30a abuts against the contact surface of the heat-conducting silicone sheet. The handle housing 20 has a control button. The ultrasonic transducer is connected to a power source through the control circuit. When the control button is pressed, the ultrasonic transducer can output the required power under the control of the circuit board. During this process, because the heat-conducting end 30a of the heat sink 30 always abuts against the contact surface of the heat-conducting silicone sheet attached to the end cap 13, the heat generated by the ultrasonic transducer 13 can be absorbed by the heat sink 30 in the first time, thereby improving the heat dissipation effect of the treatment head 10.
[0041] To ensure that the heat sink 30 abuts against the connecting end 12a, the ultrasound medical device further includes an elastic component 40. The elastic component 40 is disposed in the second receiving cavity 20a and connected to the heat sink 30, so that the heat-conducting end 30a abuts against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. In one embodiment, please refer to... Figure 5 The elastic component 40 can be an elastic arm structure with multiple bent segments. Elastic arms 43 are located at one end of the second receiving cavity 20a near the treatment head 10. Any number of elastic arms 43 are arranged in two groups, with the two groups of elastic arms 43 located above and below the second receiving cavity 20a respectively. One end of each elastic arm 43 abuts against the heat sink 30, and the other end abuts against the cavity wall of the second receiving cavity 20a. Specifically, the elastic arm 43 located above the second receiving cavity 20a abuts against the heat sink 30 at one end and against the upper cavity wall of the second receiving cavity 20a at the other end; the elastic arm 43 located below the second receiving cavity 20a abuts against the heat sink 30 at one end and against the lower cavity wall of the second receiving cavity 20a at the other end; the elastic arm 43 located above the second receiving cavity 20a... The force provided by the heat sink 30 can be decomposed into a first component force acting downward in the longitudinal direction and a second component force acting in the transverse direction towards the treatment head 10. The second component force causes the heat-conducting end 30a to abut against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. The force provided by the elastic arm 43 below the second receiving cavity 20a for the heat sink 30 can be decomposed into a third component force acting upward in the longitudinal direction and a fourth component force acting in the transverse direction towards the treatment head 10. The second and fourth components work together to ensure that the heat-conducting end 30a always abuts against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. The first and third components cancel each other out to prevent the elastic element from moving.
[0042] In another implementation, please refer to Figure 2The elastic component 40 includes an elastic element 41 and a fixing element 42. The fixing element 42 is fixedly disposed at the end of the second receiving cavity 20a away from the treatment head 10. The elastic element 41 connects the side of the heat sink 30 away from the connecting end 12a and the side of the fixing element 42 facing the connecting end 12a. At this time, the elastic force generated by the deformation of the elastic element 41 is equivalent to the force that makes the heat-conducting end 30a press against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. The structure of the elastic component 40 is simplified so that the movement form of the elastic element 41 is simple and the reliability of the effect of the elastic component 40 is improved. It is understood that the elastic element 41 can be a spring or an elastic plunger, which is not limited here.
[0043] Specifically, please refer to Figure 4 The fixing member 42 has a second guide rod 421 on the side facing the connecting end 12a, and the radiator 30 has a first guide rod 31 on the side facing away from the connecting end 12a. The first guide rod 31 and the second guide rod 421 are aligned and both extend along the length of the housing. The second guide rod 421 points towards the first guide rod 31 along its extension direction, and the first guide rod 31 points towards the second guide rod 421 along its extension direction. The elastic member 41 has a guide hole, and the first guide rod 31 and the second guide rod 421 are inserted into the guide hole. In this way, the elastic force generated by the deformation of the elastic element 41 will act in the extension direction of the first guide rod 31 and the second guide rod 421, thus pointing towards the radiator 30 and avoiding the problem of the elastic force direction deviating. It can be understood that the elastic element 41 can be provided with a guide hole at each of its two ends, with the two guide holes spaced apart. The first guide rod 31 and the second guide rod 421 are respectively inserted into one guide hole, and the two guide holes can also be connected to each other to form a channel structure. The first guide rod 31 and the second guide rod 421 are both inserted into this channel structure, which is not limited here.
[0044] Further, please refer to Figure 4To prevent the fastener 42 from becoming loose in the second receiving cavity 20a, the cavity wall of the second receiving cavity 20a is provided with a fixing groove 20b for the fastener 42 to be inserted and fixed. Specifically, a fixing structure is formed on the cavity wall of the second receiving cavity 20a through a hot melt injection molding process. The fixing structure has an insertion channel with an opening and a limiting channel on the side of the fixing structure facing the heat sink. The limiting channel connects to the insertion channel. Both the insertion channel and the limiting channel extend in the longitudinal direction. The cross-sectional width of the limiting channel in the transverse direction is smaller than the cross-sectional width of the insertion channel in the transverse direction. The insertion channel and the limiting channel form the fixing groove 20b. The limiting channel is the opening of the fixing groove 20b. Part of the structure of the fastener 42 is inserted into the insertion channel. The second guide rod 421 passes through the limiting channel. Thus, the fixing groove 20b is formed by the limiting channel and the insertion channel. Under the constraint of the elastic member 41, the fastener 42 can be prevented from lateral displacement. The opening of the insertion channel facilitates the insertion and removal of the fastener 42. In another embodiment, the fixing groove 20b only has an insertion channel extending in the longitudinal direction. Part of the structure of the fastener 42 is fixedly inserted into the insertion channel. The second guide rod 421 is located above the channel opening in the longitudinal direction. Alternatively, the fixing groove 20b is composed of an insertion channel and a limiting channel. The second guide rod 421 is located above the channel opening in the longitudinal direction. In this way, the cross-sectional area of the fastener 42 in the lateral direction, excluding the second guide rod 421, can be slightly larger than the cross-sectional area of the insertion channel. After the fastener 42 is inserted into the insertion channel, the fixing structure has a tendency to return to its original position, thereby compressing the fastener 42 and improving the fastness of the fastener 42. Further, please refer to Figure 2 The ultrasound medical device is provided with at least two elastic components 40. Each elastic component 40 includes an elastic element 41 and a fixing element 42. The arrangement of the elastic element 41 and the fixing element 42 is as explained above. By setting multiple sets of elastic components 40, greater elasticity is provided to the heat sink 30 to ensure the contact effect of the heat-conducting end 30a close to the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. It can be understood that the specific number of elastic components 40 can be adaptively set according to the installation area that the cavity wall of the heat sink 30 and the second receiving cavity 20a can provide, and is not limited here. At the same time, it is not limited here whether the multiple elastic components 40 are concentrated in a certain area of the heat sink 30 or spaced apart.
[0045] In one embodiment of this utility model, please refer to Figure 2At least two elastic components 40 are spaced apart. Specifically, when there are two elastic components 40, the two elastic components 40 can be spaced apart along the height or width direction of the heat sink 30. On the projection surface of the heat-conducting end 30a, each elastic component 40 is located close to the center or outer edge of the heat-conducting end 30a. In this case, the elastic force provided by the two elastic components 40 ensures uniform dispersion while ensuring that the heat-conducting end 30a abuts against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. When there are more than two elastic components 40, the multiple elastic components 40 are equidistantly arranged to form a regular polygon on the projection surface of the heat sink 30 on the heat-conducting end 30a, thus ensuring uniform dispersion. It can be understood that the spaced arrangement of multiple elastic components 40 can also avoid stress concentration on the cavity wall of the heat sink 30 and the second receiving cavity 20a, thus avoiding structural damage.
[0046] Further, please refer to Figure 2 The ultrasound medical device also includes a guide assembly 50, which connects the cavity wall of the second receiving cavity 20a and the heat sink 30. In one embodiment, the guide assembly 50 includes a guide block disposed on the heat sink 30 and a guide groove disposed on the cavity wall of the second receiving cavity 20a. The guide block is engaged in the guide groove. Thus, when the heat sink 30 moves, under the mutual constraint of the guide block and the guide groove, the heat sink 30 moves directionally along the groove wall of the guide groove so that the heat-conducting end 30a aligns with the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet.
[0047] In another embodiment, please refer to Figure 3The guide assembly 50 includes a guide channel 51 and a guide member 52. The guide member 52 has a third guide rod 522. The guide channel 51 is disposed in one of the cavity walls of the radiator 30 and the second receiving cavity 20a, and the third guide rod 522 is disposed in the other of the cavity walls of the radiator 30 and the second receiving cavity 20a. A portion of the third guide rod 522 is inserted into the guide channel 51. Specifically, a portion of the radiator 30 has a guide channel 51, and the cavity wall of the second receiving cavity 20a is fixedly provided with the third guide rod 522. The third guide rod 522 is inserted into the guide channel 51. The heat sink 30 is positioned within and abuts against the inner wall of the guide channel 51. Thus, under the constraint of the third guide rod 522, the heat sink 30 can move directionally along the extension direction of the guide channel 51 along the z-axis, so that the heat-conducting end 30a aligns with the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. Alternatively, the heat sink 30 is provided with the third guide rod 522, and the cavity wall of the second receiving cavity 20a has a guide channel 51. The third guide rod 522 is inserted into the guide channel 51, thus, under the constraint of the guide channel 51, the heat sink 30 can move directionally along the extension direction of the guide channel 51. The heat sink 30a is moved in a certain direction so that the end face of the heat-conducting end 30a is aligned with the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet. Simultaneously, to prevent the heat sink 30 from moving longitudinally, a limiting member is provided in the second receiving cavity 20a. In one embodiment, the limiting member can be a frame structure, fixed in the second receiving cavity 20a near the end of the treatment head 10, and sleeved on the outer surface of the heat sink 30, thus preventing the heat sink 30 from moving longitudinally. In another embodiment, the limiting member can be two limiting rods, spaced apart along the Z-axis. In the second receiving cavity 20a, two limiting rods are fixedly inserted. The limiting rods extend along the X-axis direction, or the extension direction of the limiting rods forms an angle with the X-axis direction on the plane formed by the X-axis and Y-axis. This is not limited here. Part of the structure of the heat sink 30 is located between the two limiting rods. The heat sink 30 is subject to the movement constraint formed by the two limiting rods in the Z-axis direction, which prevents the heat sink 30 from moving in the Z-axis direction. Thus, under the elastic force of the elastic component 40 and the guiding action of the guiding component 50, the heat sink 30 moves directionally in the Y-axis direction between the two limiting rods.
[0048] Specifically, please refer to Figure 3The guide assembly 50 includes a guide channel 51 and a guide member 52. The guide channel 51 is located on the heat sink 30 and has an oblong hole structure. The guide channel 51 is longitudinally connected to the second receiving cavity 20a. The third guide rod 522 can pass through the guide channel 51 and be fixedly inserted into the cavity wall of the second receiving cavity 20a. At the same time, the outer peripheral surface of the third guide rod 522 abuts against the inner wall of the guide channel 51. Thus, under the guiding action of the guide channel 51 and the constraint action of the inner wall of the guide channel 51, the heat sink 30 can be directionally moved so that the heat-conducting end 30a is aligned and abuts against the end face of the connecting end 12a or the contact surface of the heat-conducting silicone sheet.
[0049] In one embodiment of this utility model, please refer to Figure 3 The guide member 52 includes a limiting head 521 and a third guide rod 522 connected to the limiting head 521. The side of the limiting head 521 facing the third guide rod 522 abuts against the radiator 30. The distance between the side of the limiting head 521 facing the third guide rod 522 and the inner bottom wall of the second receiving cavity 20a allows the radiator 30 to move slightly in the longitudinal direction, so that the elastic force applied by the elastic component can drive the radiator 30 to move in the transverse direction. Thus, by setting the limiting head 521 and the third guide rod 522 of the cylindrical structure in conjunction with the waist-shaped hole 51, the movement of the radiator 30 can be constrained in the longitudinal direction while the radiator 30 can be oriented in the transverse direction.
[0050] Furthermore, the outer peripheral surface of the third guide rod 522 is provided with a first thread, the inner wall of the second receiving cavity 20a is provided with a mounting groove, the inner peripheral wall of the mounting groove is provided with a second thread adapted to the first thread, and the guide member 52 is screwed to the handle housing 20. In this way, the guide member 52 can be quickly disassembled and assembled, and the threaded connection between the two can adjust the distance between the limiting head 521 and the radiator 30, thereby facilitating the movement of the radiator 30.
[0051] In one embodiment of this utility model, please refer to Figure 4To ensure the directional movement of the radiator 30 within the second receiving cavity 20a, the ultrasonic medical device also includes a limiting seat 60. The limiting seat 60 can be fixed to the end of the connecting end 12a of the handle housing 20 by snap-fit, plug-in, or other means, or formed integrally with the handle housing 20 through hot-melt injection molding or other processing techniques; no limitation is made here. The limiting seat 60 is provided with a limiting hole 60a, which penetrates the limiting seat 60 in the transverse direction to connect to the second receiving cavity. The heat-conducting end 30a of the radiator 30 is aligned and can abut against the connecting end through the limiting hole 60a. Under constraint, the heat-conducting end 30a of the heat sink 30 can be prevented from deviating from the end face of the connecting end 12a. Specifically, the heat-conducting end 30a of the heat sink 30 can be fully exposed through the limiting hole 60a to abut against the connecting end; alternatively, the heat-conducting end 30a of the heat sink 30 can be located within the limiting hole 60a and flush with the surface of the limiting seat 60 to abut against the connecting end 12a; or the heat-conducting end 30a of the heat sink 30 can be located within the limiting hole 60a, with the end face of the connecting end 12a or the surface of the thermally conductive silicone pad extending into the limiting hole 60a to abut against the heat-conducting end 30a of the heat sink 30. No limitation is made here. It is understood that the limiting seat 60 and the heat sink 30 can be fitted with a clearance to ensure directional movement, or they can be fitted with a transition fit to ensure directional movement while facilitating assembly and disassembly. Therefore, the assembly method between the limiting seat 60 and the heat sink 30 is not limited.
[0052] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
