Description
Technical Field
The utility model relates to a driving mechanism and a hand tool of an ultrasonic therapeutic apparatus comprising the driving mechanism.
Background
High Intensity Focused Ultrasound (HIFU) therapy is a non-invasive treatment technique, and the principle thereof is to convert input electric power into mechanical power (i.e., ultrasonic waves) by using an ultrasonic transducer and output the mechanical power, then focus the output ultrasonic waves and apply the focused ultrasonic waves to a region to be treated of human tissue, and form high temperature in the region to be treated by using the thermal effect of the ultrasonic waves in the focused region, thereby treating the region to be treated.
Since the region to be treated generally has a relatively large area, and the area of the focus region where the energy density can achieve the treatment effect is generally relatively small, when the whole region to be treated is treated, the region to be treated needs to be divided into a plurality of discontinuous unit regions similar to the focus region, and each unit region needs to be treated separately. In view of the above, the existing high intensity focused ultrasound treatment apparatus generally comprises an ultrasound transducer, and a driving mechanism, wherein the driving mechanism can be used for driving the ultrasound transducer to move so as to respectively treat each unit area.
However, in the above-mentioned conventional focused ultrasound treatment apparatus, since the stroke of the driving mechanism may not be accurately detected and confirmed, the ultrasonic transducer may not be accurately moved to a desired unit region or may not be timely moved away from a unit region that has been treated, and thus, the treatment effect on the region to be treated may be poor. Therefore, it is necessary to provide a driving mechanism capable of detecting the stroke to drive the ultrasonic transducer to move.
Disclosure of Invention
The present invention has been made in view of the above-described conventional circumstances, and an object thereof is to provide a drive mechanism capable of detecting a stroke, and a hand piece of an ultrasonic treatment apparatus including the drive mechanism.

In the utility model, the driving mechanism comprises a rotating motor with a rotor and an output shaft, the output shaft moves along a straight line under the driving of the rotor, and when the light blocking sheet rotates along with the rotor, the rotation number of the light blocking sheet can be calculated according to the times that the first receiving part receives the optical signals emitted by the first emitting part, so that the stroke of the output shaft is calculated, and therefore, the stroke of the output shaft can be detected through the driving mechanism.
In the drive mechanism according to the present invention, the rotation of the rotor by a predetermined angle may correspond to the output shaft traveling a predetermined distance. Thus, stroke detection can be facilitated.
In addition, in the drive mechanism according to the present invention, optionally, the light-blocking sheet has a disk shape and has at least one light-transmitting hole arranged in a circumferential direction.
In addition, in the driving mechanism according to the present invention, optionally, the at least one light transmitting hole is uniformly distributed along a circumferential direction of the light blocking sheet. Thus, the stroke detection can be facilitated.
In addition, in the driving mechanism according to the present invention, optionally, the first emitting portion emits light in a direction parallel to a central axis of the light-blocking sheet, and a distance of each light-transmitting hole from the central axis of the light-blocking sheet is equal to a distance of the light emitted by the emitting portion from the central axis of the light-blocking sheet.
In the driving mechanism according to the present invention, when the light-transmitting hole is rotated to a position between the first emitting portion and the first receiving portion, the light emitted from the first emitting portion may be transmitted to the first receiving portion through the light-transmitting hole.
In addition, the driving mechanism according to the present invention may further include a second optical sensor having a second emitting portion and a second receiving portion, wherein the second emitting portion and the second receiving portion are respectively provided on opposite sides of the output shaft, and the light emitted from the second emitting portion is blocked by the output shaft when the output shaft is located at the initial position. In this case, whether the output shaft is located at the initial position can be sensed by the second optical sensor.
Another aspect of the present invention provides a hand piece of an ultrasonic treatment apparatus, which includes the driving mechanism of the first aspect of the present invention and an ultrasonic transducer, wherein an output shaft of the driving mechanism abuts against the ultrasonic transducer and drives the ultrasonic transducer to move. In this case, the driving mechanism can drive the ultrasonic transducer to move, and the stroke of the ultrasonic transducer is detected, so that the ultrasonic transducer can accurately move to a desired unit area and timely leave the unit area which is treated, and therefore, the treatment effect of the ultrasonic treatment apparatus on the area to be treated can be improved.

In the following description, the same components are denoted by the same reference numerals, and redundant description thereof is omitted. The drawings are schematic and the ratio of the dimensions of the components and the shapes of the components may be different from the actual ones.

The utility model relates to a drive mechanism capable of detecting a stroke. The drive mechanism according to the present invention may also be referred to as an actuator, a propulsion mechanism, or the like, but it should be understood that the above-mentioned names are for the drive device capable of stroke detection according to the present embodiment, and should not be construed as limiting.
It should be noted that, in the present invention, the terms of orientation or relative terms of orientation such as "one side", "opposite side", "upward", "downward", "upper surface", "lower surface", and the like are used with reference to the general operational attitude, and should not be construed as limiting.
Hereinafter, the drive mechanism 10 according to the present invention will be described with reference to the drawings.
Fig. 1 is a schematic diagram showing a drive mechanism 10 according to an example of the present invention. Fig. 2 is a schematic sectional view showing a drive mechanism 10 according to an example of the present invention. Note that, in fig. 2, parts of members and lines (for example, a housing) that may cause a shield are omitted in order to more clearly show the internal structure of the drive mechanism 10.
In the present embodiment, the drive mechanism 10 may include a rotary electric machine 11, and an output shaft 12 (see fig. 1). The rotary electric machine 11 may have a rotor 111 (see fig. 2) that rotates in operation. The output shaft 12 may be coupled to the rotor 111 and moved in a straight line (e.g., in a direction of D1 or D2 as shown in fig. 2) by the driving action of the rotor 111. In some examples, the rotary electric machine 11 may be coupled to the rotor 111 by a coupling 112.
In some examples, output shaft 12 may be driven to travel a predetermined distance along a straight line when rotor 111 is rotated a predetermined angle. In other words, the rotation of the rotor 111 by a predetermined angle may correspond to the output shaft 12 traveling a predetermined distance. Thus, the stroke detection can be facilitated. For example, when the rotor 111 rotates one turn (360 degrees), the output shaft 12 may travel 0.1cm along a straight line. The present embodiment is not limited to this, and may be provided as needed.
In some examples, the output shaft 12 may be a lead screw (e.g., a ball screw), and the rotor 111 may be a lead screw nut that is fitted around the lead screw. Thereby, the rotary motion of the lead screw nut can be converted into the linear motion of the lead screw.
Fig. 3 is a schematic diagram showing the light-blocking sheet 13 according to the example of the present invention.
In some examples, the drive mechanism 10 may include a light barrier 13 (see fig. 2 and 3). The light blocking sheet 13 may be coupled to the rotor 111 and rotate with the rotor 111. Specifically, the light blocking sheet 13 may be sleeved on the outer circumference of the rotor 111, and when the rotor 111 rotates by a predetermined angle, the light blocking sheet 13 also rotates by the predetermined angle along with the rotor 111. For example, when the rotor 111 rotates one turn (360 degrees), the light-blocking sheet 13 may also rotate one turn (360 degrees). In some examples, the light blocking sheet 13 may have a through hole 132 for passing the rotor 111 so as to be fitted around the outer circumference of the rotor 111 (see fig. 3).
In some examples, the drive mechanism 10 may include a first light sensor 14 (see fig. 2). The first photosensor 14 may have a first emitting portion 141 and a first receiving portion 142 (see fig. 2) respectively disposed at opposite sides of the light-blocking sheet 13. The first transmitting part 141 may transmit an optical signal toward the first receiving part 142. The first receiving part 142 may receive the optical signal emitted by the first emitting part 141. In fig. 2, an arrow schematically represents an optical signal emitted by the first emitting part 141 toward the first receiving part 142.
In some examples, at least a portion of the light barrier 13 is opaque. In this case, when the light-impermeable portion of the light-blocking sheet 13 is rotated to a position between the first emitting portion 141 and the first receiving portion 142, the light signal emitted from the first emitting portion 141 can be blocked, and at this time, the stroke of the output shaft 12 can be estimated by estimating the number of rotations of the light-blocking sheet 13 based on the number of times the first receiving portion 142 receives the light signal emitted from the first emitting portion 141, and the stroke of the output shaft 12 can be detected by the driving mechanism 10.
In some examples, the light-blocking sheet 13 may have a disk shape, and the light-blocking sheet 13 may have at least one light transmission hole 131 (see fig. 2 and 3) arranged along a circumferential direction. For example, in the example shown in fig. 3, the light-blocking sheet 13 may have 4 light-transmitting holes 131 (i.e., light-transmitting holes 131a, light-transmitting holes 131b, light-transmitting holes 131c, and light-transmitting holes 131 d). In this case, during operation, when the first receiving portion 142 receives the optical signal emitted by the first emitting portion 141 4 times, it means that the light blocking sheet 13 rotates by one turn, that is, the rotor 111 rotates by one turn, so that the stroke of the output shaft 12 can be estimated. The accuracy of detecting the stroke can be advantageously improved by providing the plurality of light transmission holes 131.
In some examples, the number of the light transmission holes 131 may be set according to actual conditions. For example, the light-blocking sheet 13 may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 light-transmitting holes 131.
In some examples, the at least one light transmission hole 131 on the light-blocking sheet 13 may be uniformly distributed along a circumferential direction of the light-blocking sheet 13 (see fig. 3). In this case, the stroke detection can be facilitated.
In some examples, the first emitting portion 141 may emit light in a direction parallel to a central axis of the light-blocking sheet 13, and a distance of each light transmission hole 131 from the central axis of the light-blocking sheet 13 is equal to a distance of the light emitted by the emitting portion from the central axis of the light-blocking sheet 13. In this case, when the light-transmitting hole 131 is rotated to a position between the first emitting portion 141 and the first receiving portion 142, the light emitted from the first emitting portion 141 can be transmitted to the first receiving portion 142 through the light-transmitting hole 131.
Fig. 4A is a schematic diagram showing the output shaft 12 in an initial position according to an example of the present invention. Fig. 4B is a schematic diagram showing that the output shaft 12 according to the example of the present invention is not located at the initial position.
In some examples, the drive mechanism 10 may further include a second light sensor 15 (see fig. 4A). The second light sensor 15 may have a second emitting portion 151 and a second receiving portion 152 (see fig. 4A) respectively disposed on opposite sides of the output shaft 12. The second transmitting part 151 may transmit an optical signal toward the second receiving part 152. The second receiving part 152 may receive the optical signal emitted by the second emitting part 151. In fig. 4A and 4B, arrows schematically represent optical signals emitted by the second emitting portion 151 toward the second receiving portion 152.
In some examples, the output shaft 12 may be in an initial position (see fig. 4A). As shown in fig. 4A, when the output shaft 12 is located at the initial position, the light emitted by the second emitting portion 151 may be blocked by the output shaft 12; as shown in fig. 4B, when the output shaft 12 is not located at the initial position, the second receiving portion 152 may receive the optical signal emitted by the second emitting portion 151. In this case, whether the output shaft 12 is located at the initial position can be sensed by the second optical sensor 15. That is, the drive mechanism 10 can also detect the return of the output shaft 12.
Another aspect of the utility model relates to a hand piece for an ultrasonic treatment apparatus. In the present invention, the hand tool of the ultrasonic therapeutic apparatus may be simply referred to as a hand tool. Hereinafter, the hand piece of the ultrasonic treatment apparatus according to the present invention will be described with reference to the drawings.
Fig. 5 is an overall schematic view showing the hand tool 1 of the ultrasonic treatment apparatus according to the example of the present invention.
In this embodiment, the handpiece 1 may include the drive mechanism 10 according to the first aspect of the present invention, and an ultrasonic transducer 20 (see fig. 5). The ultrasonic transducer 20 can convert the input electric power into mechanical power (i.e., ultrasonic waves) and output the mechanical power, then focus and apply the output ultrasonic waves to the region to be treated of the human tissue, and treat the region to be treated by using the thermal effect of the ultrasonic waves at the focused region to form high temperature at the region to be treated.
In some examples, output shaft 12 of drive mechanism 10 may abut ultrasound transducer 20 and drive ultrasound transducer 20 in motion. In this case, the driving mechanism 10 can drive the ultrasonic transducer 20 to move, and the stroke detection of the output shaft 12 is equivalent to the stroke detection of the ultrasonic transducer 20, so that the ultrasonic transducer 20 can accurately move to a desired unit region in the region to be treated and timely leave the treated unit region, thereby being beneficial to improving the treatment effect of the hand piece 1 of the ultrasonic treatment apparatus on the region to be treated.
In some examples, the ultrasonic transducer 20 may be removably coupled (e.g., by snap-fit) to the drive mechanism 10. In this case, the ultrasonic transducer 20 can be easily attached and detached.
In some examples, as described above, the drive mechanism 10 may also perform a reset detection of the output shaft 12. When it is applied to the handpiece 1 of an ultrasonic treatment apparatus, the ultrasonic transducer 20 can also be reset-detected by the drive mechanism 10. Thus, treatment of the area to be treated can be facilitated.
While the utility model has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the utility model in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the utility model, and such modifications and variations are within the scope of the utility model.
