Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a treatment hand and an ultrasonic therapy device. Background Technology

[0002] Ultrasound therapy devices are medical devices that use the energy effects of ultrasound waves (mainly mechanical and thermal effects) to treat or intervene in human tissues. The core difference between them and diagnostic ultrasound (such as B-mode ultrasound) lies in their purpose and energy intensity: diagnostic ultrasound aims for safe imaging, while therapeutic devices use higher-intensity ultrasound waves to produce specific biological effects to achieve therapeutic goals. Therefore, ultrasound therapy devices are currently widely used in tissue heating, tumor ablation, pain management, and cosmetic skincare.

[0003] However, since current ultrasound treatment heads are usually directly snapped and fixed to the ultrasound treatment handpiece, they cannot be dynamically adjusted according to the shape and depth of the treatment area. This can result in incomplete contact between the treatment head and the patient's skin, which can further reduce the efficiency of ultrasound energy transmission. Furthermore, the small contact area between the treatment head and the patient's skin may even cause discomfort during treatment. Incomplete contact between the treatment head and the patient's skin can also lead to the treatment head outputting ultrasound energy to non-treatment areas. Utility Model Content

Detailed Implementation

[0047] 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.

[0048] This utility model provides a treatment handpiece that can be applied to an ultrasound therapy device or an electrotherapy device (radiofrequency therapy or electrostimulation therapy). When the treatment handpiece of this application is applied to an ultrasound therapy device, it can solve the problems that the treatment head cannot be dynamically adjusted according to the shape and depth of the treatment area, which leads to incomplete contact between the treatment head and the patient's skin and low ultrasound energy transmission efficiency, as well as the problems of causing treatment discomfort and easily causing the treatment head to output ultrasound energy to non-treatment areas.

[0049] like Figure 1 As shown, and in combination Figures 2 to 6 This utility model provides a therapeutic hand tool. Figure 1 This is a schematic diagram of the structure of a treatment handpiece, which includes: a treatment head 1, a handle 2, and a movable connector 3;

[0050] One end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 can swing in multiple directions and extend and retract along the normal direction of the plane where the end face of the connecting end of the handle 2 is located.

[0051] It should be noted that one end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 swings in multiple directions. When the treatment head 1 swings in multiple directions, there are at least two swing directions, namely, swinging back and forth or swinging left and right.

[0052] It should also be noted that, since one end of the movable connector 3 is connected to the connecting end of the handle 2 and the other end is connected to the treatment head 1, the treatment head 1 can extend and retract along the normal direction of the plane containing the end face of the connecting end of the handle 2. Thus, when treating a patient, the treatment head 1 first contacts the patient's skin, and then the handle 2 continues to move closer to the patient's skin. At this time, the movable connector 3 shortens. When the treatment head 1 moves away from the area to be treated (within the extension and retraction range of the movable connector 3), it can extend through the movable connector 3 to keep the treatment head 1 in complete contact with the patient's skin. When the treatment head 1 treats uneven areas of the patient, the movable connector 3 can extend and shorten during the movement of the treatment head 1 to ensure that the treatment head 1 always maintains complete contact with the patient's skin.

[0053] It is worth noting that the swing direction of the treatment head 1 in this application can be an even number (such as 2, 4, 8, etc.) or an odd number (such as 3, 5, 7, etc.), and those skilled in the art can choose according to their needs.

[0054] In this embodiment of the invention, one end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 can swing in multiple directions and extend and retract along the normal direction of the plane containing the end face of the connecting end of the handle 2. With the treatment handpiece disclosed above, since the treatment head of this application can swing in multiple directions and extend and retract relative to the handle 2 through the movable connector 3, the treatment head 1 of this application can be dynamically adjusted according to the shape and depth of the patient's treatment area, thereby ensuring complete contact between the treatment head 1 and the patient's skin, ensuring the efficiency of ultrasonic energy transmission, avoiding treatment discomfort caused by reduced ultrasonic energy transmission efficiency, and effectively preventing the treatment head 1 from outputting ultrasonic energy to non-treatment areas.

[0055] Specifically, the movable connector 3 includes: a first slider 31 and a second slider 32;

[0056] The connecting end of the treatment head 1 is provided with a first groove 11 for sliding the first slider 31 along the first direction;

[0057] The connecting end of the handle 2 is provided with a second groove 21 for sliding the second slider 32 along the second direction, wherein the second direction is different from the first direction;

[0058] The first slider 31 is provided with a first connector 311 at the end away from the treatment head 1;

[0059] The second slider 32 is provided with a second connector 322 at the end away from the handle 2, which is connected to the first connector 311.

[0060] It should be noted that, based on the above scheme, this application sets the movable connector 3 as a first slider 31 and a second slider 32, and provides a first groove 11 for the first slider 31 to slide along a first direction at the connecting end of the treatment head 1, and a second groove 21 for the second slider 32 to slide along a second direction at the connecting end of the handle 2, with the second direction being different from the first direction. The first slider 31 has a first connector 311 at the end away from the treatment head 1, and the second slider 32 has a second connector 322 connected to the first connector 311 at the end away from the handle 2. With the above-disclosed treatment handpiece, since the first groove 11 for the first slider 31 to slide along a first direction is provided at the connecting end of the treatment head 1, and the second groove 21 for the second slider 32 to slide along a second direction is provided at the connecting end of the handle 2, and the second direction is different from the first direction, the treatment head 1 can swing relative to the handle 2. Therefore, when facing treatment areas of different shapes, the treatment head 1 can swing at a certain angle, ensuring complete contact between the treatment head 1 and the patient's skin.

[0061] It is worth noting that this application can achieve the swinging of the treatment head 1 relative to the handle 2 by the cooperation of the first slider 31 and the first slide groove 11, and the cooperation of the second slider 32 and the second slide groove 21. Alternatively, the swinging of the treatment head 1 relative to the handle 2 can be achieved by the cooperation of the first slider 31 and the first slide groove 11, and the cooperation of the second slider 32 and the second slide groove 21.

[0062] This utility model embodiment features a first groove 11 for sliding a first slider 31 along a first direction at the connecting end of the treatment head 1, and a second groove 21 for sliding a second slider 32 along a second direction at the connecting end of the handle 2, with the second direction being different from the first direction. A first connector 311 is provided at the end of the first slider 31 away from the treatment head 1, and a second connector 322 connected to the first connector 311 is provided at the end of the second slider 32 away from the handle 2. Through the aforementioned treatment handpiece, the treatment head 1 can swing relative to the handle 2 by the cooperation of the first slider 31 and the first groove 11, and the cooperation of the second slider 32 and the second groove 21. Therefore, the treatment head 1 of this application can be dynamically adjusted according to the shape of the patient's treatment area, thereby ensuring complete contact between the treatment head 1 and the patient's skin, ensuring the efficiency of ultrasound energy transmission, avoiding treatment discomfort caused by reduced ultrasound energy transmission efficiency, and effectively preventing the treatment head 1 from outputting ultrasound energy to non-treatment areas.

[0063] Specifically, the connecting end of the treatment head 1 is provided with a protrusion 12;

[0064] The lower surface of the protrusion 12 has an arc-shaped groove;

[0065] The first groove 11 is formed along the arc surface of the arc-shaped groove;

[0066] The first slider 31 has an arc-shaped structure;

[0067] The connecting end of the handle 2 is provided with an arc-shaped protrusion 22;

[0068] The second groove 21 is opened along the arc surface extension direction of the arc protrusion 22;

[0069] The second slider 32 has an arc-shaped structure.

[0070] It should be noted that a protrusion 12 is provided at the connecting end of the treatment head 1, and an arc-shaped groove is provided on the lower surface of the protrusion 12. The first slide groove 11 is opened along the arc surface extension direction of the arc groove, and the first slider 31 is set as an arc structure. Thus, the first slider 31 can slide more smoothly in the first slide groove 11 and can ensure that the treatment head 1 swings relative to the handle 2.

[0071] An arc-shaped protrusion 22 is provided at the connecting end of the handle 2, and the second slide groove 21 is opened along the arc surface extension direction of the arc-shaped protrusion 22. The second slider 32 is set as an arc structure, so that the second slider 32 can slide more smoothly in the second slide groove 21 and can ensure that the treatment head 1 can swing relative to the handle 2 in another direction.

[0072] Based on the above-disclosed treatment handpiece, those skilled in the art can, according to the above scheme, set the protrusion 12 at the connecting end of the treatment head 1 at the connecting end of the handle 2, set the arc-shaped protrusion 22 at the connecting end of the handle 2 at the connecting end of the treatment head 1, and set the arc-shaped groove on the lower surface of the protrusion 12, and set the first slide groove 11 along the arc-shaped groove extending direction, and set the first slider 31 as an arc-shaped structure, so that the first slider 31 can slide more smoothly in the first slide groove 11, and can ensure that the treatment head 1 swings relative to the handle 2, and set the second slide groove 21 along the arc-shaped protrusion 22 extending direction, and set the second slider 32 as an arc-shaped structure, so that the second slider 32 can slide more smoothly in the second slide groove 21, and can ensure that the treatment head 1 swings relative to the handle 2 in another direction.

[0073] Furthermore, the movable connector also includes: elastic element 33;

[0074] The second connector 322 is in telescopic cooperation with the first connector 311;

[0075] The elastic element 33 is disposed between the first connector 311 and the second connector 322. The elastic element 33 is used to provide elastic restoring force when the first connector 311 moves toward the handle 2.

[0076] It should be noted that the second connector 322 is telescopically coupled with the first connector 311, and the elastic element 33 is positioned between the first connector 311 and the second connector 322. The elastic element 33 provides elastic restoring force when the first connector 311 moves toward the handle 2. Thus, during patient treatment, the treatment head 1 first contacts the patient's skin, and then the handle 2 continues to move closer to the patient's skin. At this time, the second connector 322 and the first connector 311 shorten, and together with the first connector 311, they compress the elastic element 33, causing the elastic element 33 to deform and store energy. When the treatment head 1 moves away from the area to be treated (within the telescopic range of the movable connector 3), the first connector 311 can extend outward under the action of the elastic restoring force provided by the elastic element 33, ensuring that the treatment head 1 always maintains complete contact with the patient's skin.

[0077] When the treatment head 1 treats the patient's uneven areas, the first connector 311 will extend or retract autonomously during the movement of the treatment head 1, so that the treatment head 1 always maintains complete contact with the patient's skin.

[0078] In a specific application, namely in an ultrasonic therapy device, the elastic element 33 enables the treatment head 1 to make micro-movements in the direction of the transducer emitting surface.

[0079] Furthermore, the second connector 322 has a movable cavity 312 for the first connector 311 to extend into;

[0080] The first connector 311 has a first limiting protrusion on the periphery of the end away from the treatment head 1;

[0081] The inner wall of the second connector 322 at the end away from the handle 2 is provided with a second limiting protrusion that restricts the passage of the first limiting protrusion;

[0082] One end of the elastic element 33 abuts against the end of the first slider 31 away from the handle 2, and the other end of the elastic element 33 abuts against the end of the second slider 32 away from the treatment head 1.

[0083] It should be noted that the second connector 322 can be provided with a movable cavity 312 for the first connector 311 to extend into, so as to realize the telescopic connection between the second connector 322 and the first connector 311. Alternatively, the first connector 311 can be provided with a movable cavity 312 for the second connector 322 to extend into, so as to realize the telescopic connection between the second connector 322 and the first connector 311. Those skilled in the art can choose according to their needs.

[0084] By providing a first limiting protrusion on the periphery of the end of the first connector 311 away from the treatment head 1, and providing a second limiting protrusion on the inner wall of the end of the second connector 322 away from the handle 2 to restrict the passage of the first limiting protrusion, the first connector 311 and the second connector 322 can be prevented from separating by the cooperation of the first limiting protrusion and the second limiting protrusion after the first connector 311 is inserted into the movable cavity 312 of the second connector 322.

[0085] Furthermore, the first connector 311 is a cylindrical body, and the second connector 322 is a cylindrical structure formed by multiple spring flaps;

[0086] Alternatively, the second connector 322 may be a cylindrical body, and the first connector 311 may be a cylindrical structure formed by multiple spring flaps.

[0087] It should be noted that this application may configure the first connector 311 as a cylindrical body and the second connector 322 as a cylindrical structure formed by multiple spring flaps, or the second connector 322 may be configured as a cylindrical body and the first connector 311 as a cylindrical structure formed by multiple spring flaps. Those skilled in the art may choose according to their needs.

[0088] It should also be noted that when the first connecting member 311 is a cylindrical body and the second connecting member 322 is a cylindrical structure formed by multiple spring flaps, the first limiting protrusion can be a limiting member with an annular structure; when the second connecting member 322 is a cylindrical body and the first connecting member 311 is a cylindrical structure formed by multiple spring flaps, the second limiting protrusion can be a limiting member with an annular structure.

[0089] It is worth noting that the first connector 311 and the second connector 322 can also be set as cylindrical structures. In order to ensure that the first connector 311 can extend into the movable cavity 312 of the second connector 322, and to ensure that the first limiting protrusion and the second limiting protrusion cooperate to prevent the first connector 311 from separating from the second connector 322, the first protrusion and the second protrusion can be set as linear protrusion structures with a preset distance. However, the preset distance must be greater than the length of the linear protrusion structure so that the first connector 311 can extend into the movable cavity 312 of the second connector 322.

[0090] Specifically, the extension range of the treatment head 1 along the normal direction of the plane containing the end face of the connecting end of the handle 2 is within 2mm.

[0091] It should be noted that by setting the extension range of the treatment head 1 along the normal direction of the plane containing the end face of the connecting end of the handle 2 to within 2mm, the treatment head 1 can be finely adjusted in the Z direction. Thus, when the treatment head 1 moves to the depression of the patient's skin, the movable connecting piece 3 extends and drives the treatment head 1 away from the handle 2, so that the treatment head 1 makes complete contact with the patient's skin.

[0092] Furthermore, when the treatment head 1 swings in multiple directions, these multiple directions are parallel to the plane containing the end face of the connecting end of the handle 2;

[0093] When the treatment head swings, the angle between the axis of the treatment head and the normal direction of the plane containing the end face of the handle connection end is 0° to 10°.

[0094] It should be noted that the angle between the axis of the treatment head 1 and the normal direction of the plane containing the end face of the connecting end of the handle 2 is 0° to 10°. This allows for fine-tuning of the treatment head 1 in multiple directions. When facing treatment areas of different shapes, the treatment head 1 can rotate at a certain angle to ensure complete contact between the treatment head 1 and the patient's skin. At the same time, it can control the distribution range of the ultrasonic energy output by the treatment head. That is, the focal point of the ultrasonic energy output by the treatment head is only distributed within a certain depth range of the skin tissue to be treated, avoiding excessive swinging of the treatment head and outputting ultrasonic energy to non-treatment areas.

[0095] Traditional treatment heads typically have a fixed treatment depth. If a treatment head has a depth of 10mm and is placed directly against the skin tissue to be treated, the ultrasound energy output is focused 10mm below the treated skin tissue. If the treatment head is oscillated at a certain angle during treatment, the output ultrasound energy will fluctuate within a certain range below the treated skin tissue. For example, if a treatment head has a depth of 10mm and oscillates at an angle of 0°-60°, the output ultrasound energy will be distributed between 10*cos60° and 10*cos0° (5mm-10mm) below the treated skin tissue. Therefore, if the oscillation angle is too large, the output ultrasound energy may be distributed to non-treatment areas, affecting the treatment effect.

[0096] It is worth noting that, since the extension range of the movable connector 3 in this application is 2mm, and the angle between the axis of the treatment head 1 and the normal direction of the plane containing the end face of the connecting end of the handle 2 when the treatment head swings is 0° to 10°, the treatment head 1 in this application can only be finely adjusted, thereby effectively avoiding the problem of the treatment head 1 outputting ultrasonic energy to the non-treatment area due to excessive swing amplitude.

[0097] Specifically, the elastic element 33 is a spring;

[0098] The first connector 311 has a mounting groove for mounting the elastic element 33 at the end away from the treatment head 1.

[0099] It should be noted that a spring is a mechanical part that works by utilizing elasticity. It is mainly made of elastic materials (such as spring steel) and can deform under the action of external force, and return to its original shape after the external force is removed.

[0100] Springs come in a wide variety of types. Based on their shape, they can be mainly classified as helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0101] It is worth noting that the elastic element 33 in this application can be a spring, a sheet, or other components that can produce elastic deformation when compressed by external force. Those skilled in the art can choose according to their needs.

[0102] Furthermore, the first direction is perpendicular to the second direction.

[0103] It should be noted that the first and second directions are set as perpendicular, as shown in the reference. Figure 6The first direction is the X direction (including positive and negative directions), and the second direction is the Y direction (including positive and negative directions). Through the cooperation of the first slider 31 and the first slide groove 11, and the cooperation of the second slider 32 and the second slide groove 21, the treatment head 1 can swing left and right and back and forth relative to the handle 2. That is, in the treatment device, the first and second direction swings are radial to the transducer emitting surface of the ultrasonic treatment head, which further ensures complete contact between the treatment head 1 and the patient's skin and further ensures the ultrasonic energy transmission efficiency, avoiding treatment discomfort caused by reduced ultrasonic energy transmission efficiency.

[0104] Furthermore, the treatment handpiece also includes: pressure sensor 4;

[0105] The pressure sensor 4 is disposed on the second slider 32 and is located between the second slider 32 and the elastic member 33.

[0106] It should be noted that pressure sensor 4 is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to a certain rule; pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Based on different types of test pressure, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0107] Pressure sensors are one of the most commonly used sensors in industrial practice. They are widely used in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, power, shipbuilding, machine tools, pipelines and many other industries.

[0108] In this application, the pressure sensor 4 is disposed on the second slider 32 and located between the second slider 32 and the elastic member 33, so that the elastic restoring force of the spring can be detected by the pressure sensor 4, so as to avoid the treatment head 1 from excessively squeezing the patient's skin and causing discomfort to the patient.

[0109] It is worth noting that the pressure sensor 4 is connected to the handle 2 device or handheld terminal for communication. Medical staff can determine whether the treatment head 1 is in close contact with the patient's skin based on the values ​​detected by the pressure sensor 4.

[0110] Furthermore, the treatment handpiece also includes: a ring-shaped protective element 5;

[0111] The annular protective element 5 is fitted onto the movable connector 3, and both ends of the annular protective element 5 are connected to the handle 2 and the treatment head 1, respectively.

[0112] It should be noted that the annular protective part 5 is a flexible part. The annular protective part 5 is sleeved on the movable connecting part 3, and the two ends of the annular protective part 5 are respectively connected to the handle 2 and the treatment head 1. Thus, when the treatment head 1 swings or retracts relative to the handle 2, it can prevent external dust from entering the movable connecting part 3 and affecting the smoothness of the movement of the treatment head 1, effectively extending the service life of the treatment handpiece.

[0113] Specifically, the annular protective component 5 is a corrugated pipe.

[0114] It should be noted that the annular protective component 5 can be a corrugated pipe or an annular component made of other flexible materials (such as a leather sleeve, rubber sleeve, cloth sleeve, etc. with annular structure). Those skilled in the art can choose according to their needs.

[0115] It should also be noted that the corrugated pipe of this application is a tubular elastic element with transverse corrugations, mainly made of metal (such as stainless steel and carbon steel) and plastic. It is widely used in petrochemical, power, instrumentation, metallurgy and other industries, as well as in media transportation, mechanical equipment and other fields.

[0116] In this application, the corrugated tube can deform to a certain extent in accordance with the swing and / or extension of the treatment head 1. Therefore, it can keep both ends of the corrugated tube connected to the treatment head 1 and the handle 2 respectively. Thus, it can effectively prevent external dust from entering between the treatment head 1 and the handle 2 during the swing and / or extension of the treatment head 1. This can also prevent external dust from entering the movable connector 3 and affecting the smoothness of the swing and / or extension of the treatment head 1, thus effectively ensuring the service life of the treatment handpiece.

[0117] Based on the treatment handpiece provided in the above embodiments, this utility model embodiment also provides an ultrasonic therapy device, the ultrasonic therapy device comprising: a treatment handpiece;

[0118] The treatment handpiece includes: a treatment head 1, a handle 2, and a movable connector 3;

[0119] One end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 can swing in multiple directions and extend and retract along the normal direction of the plane where the end face of the connecting end of the handle 2 is located.

[0120] It should be noted that one end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 swings in multiple directions. When the treatment head 1 swings in multiple directions, there are at least two swing directions, namely, swinging back and forth or swinging left and right.

[0121] It should also be noted that, since one end of the movable connector 3 is connected to the connecting end of the handle 2 and the other end is connected to the treatment head 1, the treatment head 1 can extend and retract along the normal direction of the plane containing the end face of the connecting end of the handle 2. Thus, when treating a patient, the treatment head 1 first contacts the patient's skin, and then the handle 2 continues to move closer to the patient's skin. At this time, the movable connector 3 shortens. When the treatment head 1 moves away from the area to be treated (within the extension and retraction range of the movable connector 3), it can extend through the movable connector 3 to keep the treatment head 1 in complete contact with the patient's skin. When the treatment head 1 treats uneven areas of the patient, the movable connector 3 can extend or shorten during the movement of the treatment head 1 to ensure that the treatment head 1 always maintains complete contact with the patient's skin.

[0122] It is worth noting that the swing direction of the treatment head 1 in this application can be an even number (such as 2, 4, 8, etc.) or an odd number (such as 3, 5, 7, etc.), and those skilled in the art can choose according to their needs.

[0123] In this embodiment of the invention, one end of the movable connector 3 is connected to the connecting end of the handle 2, and the other end is connected to the treatment head 1, so that the treatment head 1 can swing in multiple directions and extend and retract along the normal direction of the plane containing the end face of the connecting end of the handle 2. With the treatment handpiece disclosed above, since the treatment head of this application can swing in multiple directions and extend and retract relative to the handle 2 through the movable connector 3, the treatment head 1 of this application can be dynamically adjusted according to the shape and depth of the patient's treatment area, thereby ensuring complete contact between the treatment head 1 and the patient's skin, ensuring the efficiency of ultrasonic energy transmission, avoiding treatment discomfort caused by reduced ultrasonic energy transmission efficiency, and effectively preventing the treatment head 1 from outputting ultrasonic energy to non-treatment areas.

[0124] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
