Description

Technical Field

[0001] This utility model relates to an ultrasonic therapy device, and more specifically, to an operating handle for an ultrasonic therapy device. Background Technology

[0002] An ultrasonic therapy device consists of a main body and an operating handle. The ultrasonic wave plate in the operating handle outputs ultrasonic energy to achieve the therapeutic purpose. The contact area between the operating handle and the skin is relatively large, especially the blade-shaped handle, which has a contact area of ​​40*60mm. However, the actual treatment area is very small, mainly because the ultrasonic energy output by the ultrasonic wave plate is micro-focused, and after acting on the subcutaneous tissue, it only forms a single focal point. Therefore, the actual treatment area of ​​a single ultrasonic treatment is this focal point and the surrounding skin tissue within a certain area.

[0003] In practical use, when the treatment area is large or curved, it is necessary to continuously and manually move the blade handle. Multiple movements are required to create multiple treatment focal points (including adjacent skin tissue) to barely form a single treatment surface that meets clinical needs. However, due to manual operation, the distance between treatment points in clinical use is often insufficient to form a complete treatment path within the target treatment surface. This often results in incomplete treatment within the treatment area or treatment extending beyond the treatment area, leading to inaccurate treatment results and poor treatment outcomes. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0027] See Figures 1-11 This utility model discloses an operating handle for an ultrasonic therapy device, comprising a handle body 1 and an ultrasonic transducer 5. A horizontal axis drive assembly 3 is installed in the handle body 1, which drives the ultrasonic transducer 5 to move axially back and forth. An angle drive assembly 4 is installed at the drive end of the horizontal axis drive assembly 3, which drives the ultrasonic transducer 5 to rotate. The ultrasonic transducer 5 is mounted on the angle drive assembly 4. A sound-transmitting membrane 2 is provided on one side of the handle body 1, which contacts the treatment surface. The ultrasonic transducer 5 faces the sound-transmitting membrane 2, so that the treatment focus generated by the ultrasonic transducer 5 can be transmitted through the sound-transmitting membrane 2 and irradiated onto the treatment area. Both the horizontal axis drive assembly 3 and the angle drive assembly 4 are electrically connected to the main body, thereby controlling the horizontal axis drive assembly 3 and the angle drive assembly 4 to drive the ultrasonic transducer 5 to move according to the required treatment path.

[0028] The operating handle of this invention can drive the ultrasonic plate 5 to move within the operating handle through the horizontal axis drive component 3 and the angle drive component 4, thereby making it movable relative to the treatment surface. By controlling its movement path within the treatment surface, the ultrasonic plate 5 can treat the points that need to be treated within the treatment surface without continuously moving the handle, thus solving the problem of inaccurate treatment area and poor treatment effect caused by the need to move the handle after treating each point in the prior art.

[0029] In this embodiment, the horizontal axis drive assembly 3 specifically includes a first motor 31, a long-shaft screw 32, a guide rail 34, and a slider 33. The first motor 31 is installed in the handle body 1. The long-shaft screw 32 is installed on the output shaft of the first motor 31. The end of the long-shaft screw 32 away from the first motor 31 is connected to the handle body 1 via a bearing 35 to improve the stability of the long-shaft screw 32 installation. The guide rail 34 is installed in the handle body 1 and is slidably connected to the slider 33, thereby preventing the slider 33 from rotating with the long-shaft screw 32. The slider 33 is threadedly connected to the long-shaft screw 32, and an angle drive assembly 4 is installed below the slider 33. The first motor 31 drives the angle drive assembly 4, on which the ultrasonic transducer 5 is mounted, to move along the long-shaft screw 32, i.e., the X-axis, thereby realizing the axial back-and-forth movement of the ultrasonic transducer 5.

[0030] The angle drive assembly 4 includes a second motor 41, a connecting rod 44, and a mounting bracket 45. The second motor 41 is mounted below the slider 33. A bracket 42 is mounted on the output shaft of the second motor 41. The bracket 42 is connected to the connecting rod 44 via a key structure 43. The mounting bracket 45 is mounted on the connecting rod 44, and the ultrasonic transducer 5 is mounted on the mounting bracket 45. Since the ultrasonic transducer 5 is fixedly mounted on the output shaft of the second motor 41, the driving action of the second motor 41 can drive the ultrasonic transducer 5 to rotate, thereby changing the irradiation position of the ultrasonic transducer 5 on the Y-axis. In this embodiment, the distance between the ultrasonic transducer 5 and the acoustic membrane 2 is 10 mm. Therefore, relative to the treatment surface, the rotation of the second motor 41 is equivalent to driving the treatment focus generated by the ultrasonic transducer 5 to move in the Y-axis direction of the treatment surface.

[0031] Preferably, a guide rod 46 is installed in the handle body 1, and the connecting rod 44 is a hollow rod. The guide rod 46 is inserted into the connecting rod 44 and forms a movable insertion with the connecting rod 44. The hollow connecting rod 44 and the guide rod 46 form a telescopic rod structure, which provides better support for the connecting rod 44 and improves the stability of the moving connecting rod 44.

[0032] In summary, the first motor 31 controls the movement of the ultrasonic plate 5 in the X-axis direction, while the second motor 41 controls the movement of the ultrasonic plate 5 in the Y-axis direction, which can realize the movement of the ultrasonic plate 5 at any position of the focal point within the treatment surface.

[0033] Because the first motor 31 has a long operating stroke and a relatively heavy load, in order to solve the problem of inaccurate positioning caused by the first motor 31 losing its step during rotation, an inertial measurement device 36 is installed on the output shaft of the first motor 31 in this embodiment to monitor whether the first motor 31 loses its step. When the first motor 31 loses its step, its inertia will change abruptly. After the control system in the main body detects this signal, it can compensate for the motor or return it to zero and start moving again to ensure its positional accuracy. Among these methods, compensating for the motor or returning it to zero and starting moving again are public technologies in the art, and this utility model does not improve upon them, so they will not be discussed further.

[0034] To ensure positioning accuracy, a code disk 47 is mounted on the bracket 42 in this embodiment, and a grating position detection device 48 is mounted on the slider 33. The code disk 47 extends into the monitoring end of the grating position detection device 48 to determine the initial angle of the output shaft of the second motor 41, thereby ensuring the accuracy of the next movement position. Similarly, the first motor 31 can also determine its initial position based on the grating position detection device 48 and the code disk 47 configured in the second motor 41.

[0035] In the specific implementation process, the main body sets the required treatment path according to the treatment surface. The specific method for setting the required treatment path is as follows: the treatment trajectory of the treatment surface is obtained, and the path is calibrated according to the treatment trajectory of the treatment surface based on the coordinate map of the acoustic membrane 2 to obtain the required treatment path. That is, the actual treatment trajectory is mapped onto the coordinate map, and the treatment path can be intuitively identified on the coordinate map to provide a movement path for subsequent ultrasound film 5 treatment. In this embodiment, the required treatment path includes a straight path, an arc path, a curved path, and a treatment path that includes all treatment points in the entire treatment surface. Figure 7 The diagram shown is a schematic of a straight path; as follows: Figure 8 and Figure 9 The diagrams shown are all schematic representations of arc-shaped paths; for example... Figure 10 The diagram shown is a schematic representation of the curved path; as follows: Figure 11 The diagram shows a treatment path that includes all treatment points in the entire treatment area. Each treatment point is marked using a sequential marking method, with the last treatment point being N.

[0036] The coordinate map of the acoustic membrane 2 is obtained as follows: the treatment diameter of the ultrasound patch in a single treatment is obtained, and the coordinate map within the range of the acoustic membrane 2 is constructed using the divisor between the area of ​​the acoustic membrane 2 and the treatment diameter. That is, the final constructed coordinate map is a planar coordinate system based on the XY axes, such as... Figure 5 As shown.

[0037] In this embodiment, the path calibration methods include sequential calibration, symmetrical calibration, and cyclic calibration. Only one of these methods needs to be used in the actual calibration process. Each calibration method is described in detail below.

[0038] The sequential labeling method involves marking treatment points sequentially on the coordinate map of the acoustic membrane 2 along the treatment trajectory of the treatment surface. That is, after mapping the treatment trajectory onto the coordinate map and determining the treatment point locations, the treatment points are marked sequentially to form a sequential sequence of treatment points, such as... Figure 7 As shown in the diagram. This method minimizes the movement distance of the ultrasound plate 5 each time, thereby reducing the movement time of the ultrasound plate 5 between treatment sessions and effectively shortening the overall treatment time. It can be applied to all types of treatment pathways.

[0039] The symmetry calibration method involves obtaining all treatment points from the coordinate graph of the acoustic membrane 2 based on the treatment trajectory of the treatment surface, and then sequentially marking the treatment points located at both ends of the treatment trajectory on the coordinate graph. For example... Figure 8 As shown, points on both sides of the treatment path mapped on the coordinate graph are used as symmetrical points and marked sequentially. Taking the endpoints of the treatment path as an example, after the ultrasound plate 5 treats the first treatment point, the output of the ultrasound plate 5 is turned off. Then, the motor moves the plate to the other endpoint as the second treatment point along a straight line between the two points, thus treating all treatment points. This method can effectively balance the treatment at various locations on the treatment surface, providing patients with a better therapeutic experience. It is generally applied to straight or curved paths.

[0040] The cyclic calibration method involves obtaining all treatment points from the coordinate map of the acoustic membrane 2 based on the treatment trajectory of the treatment surface. The number of treatment points is odd. The treatment point located in the middle of the treatment trajectory on the coordinate map is taken as the initial treatment point. Then, the treatment points on both sides of the initial treatment point are marked sequentially, and the marked points are used as the necessary points on the moving path of the ultrasonic plate 5. Specifically, this method is the opposite of the symmetrical calibration method. It starts marking points from the outer ends of the middle of the treatment path, while ensuring that the ultrasonic plate 5 moves along the trajectory of the treatment path. This setup requires the ultrasonic plate 5 to move without stopping, allowing it to re-irradiate points already treated on the path when moving between two treatment points, thus consolidating the treatment effect of the treated points. Figure 9 As shown, the initial treatment point is taken as the first treatment point. Points are marked from the left side, with the point to the left of the initial treatment point designated as the second treatment point, and the point to the right as the third treatment point, and so on. When the ultrasound plate 5 needs to move from the second treatment point to the third treatment point, it must pass through the first treatment point. This method is generally used in straight or curved paths.

[0041] The above confirms the treatment method. The specific treatment aspects will be explained below.

[0042] like Figure 5 The diagram illustrates the treatment method for a planar treatment surface. Assume the treatment surface dimensions of the ultrasound patch 5 are length X and width Y, and assume the diameter of the subcutaneous tissue treated after a single ultrasound treatment is D, including the treatment focal point and surrounding skin tissue, as shown below. Figure 6 The single treatment area is shown in the diagram. The center point of the single treatment area is the treatment point. The number of ultrasound waves that can be used in the X direction on the treatment surface is an integer of X ÷ D, yielding the value X. x This value represents the maximum number of ultrasound treatments in a single session along the X-axis of the treatment surface. Using the midpoint of this number as zero, extending left and right and multiplying by the treatment diameter D yields...X -2 X -1 Data consisting of X0, X1, X2..., with a total of X... x Similarly, in the Y direction, we can derive...Y -2 Y -1 Data including Y0, Y1, Y2..., this data contains a total of Y... y These two sets of data are written into the control program to construct a coordinate graph.

[0043] Initially, the ultrasonic transducer 5 is aligned with the center of the treatment surface, corresponding to X0 and Y0 in the data. The treatment area, i.e., the treatment surface, is then converted into coordinate information for each treatment point. Simultaneously, a suitable method is selected to calibrate the treatment path based on the treatment trajectory. The motor is driven by a drive circuit, causing the ultrasonic transducer 5 to move / rotate to the initial coordinate position, i.e., the first treatment point, thus initiating one ultrasonic treatment. After treatment, it moves to the next treatment point, and so on, until all treatment points are treated.

[0044] If the treatment trajectory is curved, since it is difficult to accurately locate the midpoint of a curve, one end of the curve can be aligned with the corner point of the treatment surface, and then the final treatment path can be marked according to the treatment trajectory. Move / rotate the ultrasound plate 5 to the initial coordinate position, start one ultrasound treatment, and then move to the next treatment point until all treatment points are completed.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
