[0045] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings. The same reference numerals in each figure represent components with the same structure or similar structures but the same functions. The nouns and pronouns for people in this patent application are not limited to specific genders.
[0046] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.
[0047] In this article, "first", "second", etc. do not indicate their importance or order, but are only used to indicate the difference between each other for the convenience of document description.
[0048] In order to make the drawings concise, each figure only schematically shows the parts related to the utility model, which do not represent the actual structure of the product.
[0049] Figure 1 The present invention is a structural schematic diagram of an exemplary implementation of a joystick for medical equipment. Figure 2 For along Figure 1 Cross-sectional view of II-II. Figure 3 For along Figure 1 The cross-sectional view of III-III in the figure. Figures 1 to 3 As shown in FIG. 1 , the operating handle of the medical device includes a handle body 10 and a sensor unit 30. In this exemplary embodiment, the sensor unit 30 is disposed in the handle body 10. Figure 1 Not visible in.
[0050] like Figure 1 and Figure 2As shown, the handle body 10 is in the shape of a hollow column and a sensing area 11 is arranged on the surface. The sensing area 11 is arranged on the outer surface of the handle body 10. The sensing unit 30 is arranged on the inner surface of the handle body 10. The sensing unit 30 is used to detect the situation that the sensing area 11 is touched, and is used to detect the situation that the sensing area 11 is pressed. Specifically, the sensing unit 30 can, for example, generate a touch detection signal when the sensing area 11 is touched by the user, and can generate a press detection signal when the sensing area 11 is pressed by the user. More specifically, the sensing unit 30 includes, for example, a capacitive sensor and a pressure sensor. The capacitive sensor is used to detect the situation that the sensing area 11 is touched, and it can, for example, generate a touch detection signal when the sensing area 11 is touched. The pressure sensor is used to detect the situation that the sensing area 11 is pressed, and it can, for example, generate a press detection signal when the sensing area 11 is pressed.
[0051] In this way, when the user's hand is holding the sensing area 11 of the handle body 10, a touch detection signal and a press detection signal can be generated. If a foreign object accidentally touches the handle body 10, only a press detection signal may be generated, but no touch detection signal. If water is attached to the outer surface of the handle body 10, only a touch detection signal may be generated, but no press detection signal may be generated.
[0052] When judging, for example, when both the touch detection signal and the press detection signal are generated, the operation behavior can be judged as a normal operation of the person, and when only the touch detection signal, only the press detection signal, or neither the touch detection signal nor the press detection signal are generated, the operation behavior can be judged as not a normal operation of the person. This can make the judgment result more accurate.
[0053] In addition, when judging, for example, the corresponding pressure value can be further calculated according to the pressure detection signal, and whether it is normal pressing or accidental pressing can be judged according to the size or change trend of the pressure value. Furthermore, while detecting whether it is triggered by a real person, it can also detect whether it is a human false trigger. This can make the judgment result more accurate.
[0054] Thereby, the operating handle of the medical device of the present exemplary embodiment is prevented from being accidentally triggered and is easy to operate.
[0055] In this illustrative embodiment, the handle body 10 is in the shape of a hollow column. Here, the handle body 10 is in the shape of a hollow column, which refers to the approximate shape of the handle body 10. The sensing area 11 is disposed on the outer surface of the handle body 10. The sensor unit 30 is disposed on the inner surface of the handle body 10. Specifically, the sensor unit 30 is connected to the inner surface of the handle body 10 by bonding, for example, but not limited thereto. Such a structure is conducive to maintaining the integrity of the outer surface of the handle body 10, so that it has better sealing performance, and is convenient for assembling the handle body 10 and the sensor unit 30.
[0056] like Figures 1 to 3 As shown, in the exemplary embodiment, the outer surface of the handle body 10 has a top surface 12 and four side surfaces 14. The top surface 12 is located at one end (i.e. Figure 1 and Figure 2 The four side surfaces 14 are distributed along the circumference of the handle body 10. Each side surface 14 and the top surface 12 is provided with a sensing area 11.
[0057] like Figure 2 and Figure 3 As shown, the sensing unit 30 includes five sensing components 31. The five sensing components 31 are arranged on the inner surface of the handle body 10. Specifically, the sensing components 31 are connected to the inner surface of the handle body 10 by bonding, for example, but not limited thereto. Each sensing component 31 corresponds to a sensing area 11 of a side surface 14 or a sensing area 11 of a top surface 12. Each sensing component 31 is used to detect the situation that its corresponding sensing area 11 is touched, and it can, for example, generate a corresponding touch detection signal when its corresponding sensing area 11 is touched. Each sensing component 31 is also used to detect the situation that its corresponding sensing area 11 is pressed, and it can, for example, generate a corresponding press detection signal when its corresponding sensing area 11 is pressed. When judging, for example, when two or more sensing components 31 generate touch detection signals and press detection signals, it is judged that the operation behavior belongs to the normal operation of the person, which can make the judgment result more accurate and help to further prevent the operating handle from being accidentally triggered.
[0058] In this exemplary embodiment, the outer surface of the handle body 10 has four side surfaces 14, and each two adjacent side surfaces 14 are perpendicular to each other. Figure 1 As shown, this makes the upper half of the handle body 10 close to a square column. The purpose of this arrangement is that when the user holds the handle body 10, the fingers are more inclined to stick to the side 14, that is, the user has a greater probability of contacting the sensing area 11, and the force is also easily concentrated in the sensing area 11. This is conducive to improving the sensitivity of the sensing. However, it is not limited to this. In other exemplary embodiments, the number and distribution of the side surfaces can be set as needed, and the side surfaces can be flat or curved, and the curved surface can facilitate hand grip.
[0059] In other exemplary embodiments, the number of sensor components 31 included in the sensor unit 30 can be adjusted as needed, and the number of sensor components 31 corresponding to the same sensing area 11 can be multiple, and these sensor components 31 can be arranged in an array, for example.
[0060] Figure 4 for Figure 1 The structure diagram of the sensor unit of the joystick is shown in FIG. Figure 4Specifically, each sensing component 31 includes, for example, a capacitive sensor 33 and a pressure sensor 34. The capacitive sensor 33 is used to detect when the sensing area 11 is touched, and can generate a touch detection signal when the sensing area 11 is touched. The pressure sensor 34 is used to detect when the sensing area 11 is pressed, and can generate a press detection signal when the sensing area 11 is pressed.
[0061] Combination Figure 3 and Figure 4 In this exemplary embodiment, the front side of the capacitive sensor 33 is attached to the inner surface of the handle body 10. The pressure sensor 34 is stacked on the back side of the capacitive sensor 33. This helps to expand the sensing range of the capacitive sensor 33 and the pressure sensor 34. Figure 4 As shown, in this exemplary embodiment, the front surface of the capacitive sensor 33 is also covered with a covering layer 37, and the capacitive sensor 33 is attached to the inner surface of the handle body 10 through the covering layer 37. The covering layer 37 has a protective effect on the capacitive sensor 33, and it may also have adhesion, for example. However, it is not limited to this, and in other exemplary embodiments, the covering layer 37 may not be provided.
[0062] like Figure 4 As shown, further, in the exemplary embodiment, each sensing assembly 31 further includes a pressure transmission plate 35 disposed between the pressure sensor 34 and the capacitive sensor 33. The pressure transmission plate 35 is used to transmit pressure through its rigidity. The pressure transmission plate 35 is, for example, a thin steel plate. This helps to improve the sensitivity of the pressure sensor.
[0063] like Figures 2 to 4 As shown, in the schematic embodiment, the sensing unit 30 also includes an inner core 32. The inner core 32 is inserted into the inner cavity 16 of the handle body 10. The sensing component 31 is bonded to the inner core 32 and attached to the inner surface of the handle body 10. This helps to improve the stability of the structure. In addition, during the manufacturing process of the operating handle, the sensing component 31 can be first bonded to the inner core 32, and then the inner core 32 can be inserted into the handle body 10 so that the sensing component 31 is attached to the inner surface of the handle body 10, which can facilitate the manufacturing of the operating handle. When the operating handle is used, the inner core 32 may also be used to provide other functions such as direction control and buttons. In other schematic embodiments, the inner core 32 may not be provided.
[0064] Figure 5 and Figure 6 A second exemplary embodiment of a joystick for a medical device is described. Figure 5 This is a cross-sectional view of the joystick, with the cutting direction being Figure 1 Same as in Ⅱ-Ⅱ, Figure 6 FIG. 3 is a schematic diagram of the structure of the sensor unit 30 of the operating handle. Figure 1The same or similar parts of the operating handle shown are not repeated here, and the difference lies in the sensor component 31.
[0065] like Figure 5 and Figure 6 As shown, in this exemplary embodiment, the capacitive sensor 33 and the pressure sensor 34 of each sensor assembly 31 are not arranged in an overlapping manner, but are respectively bonded to the inner core 32 and attached to the inner surface of the handle body 10 through the covering layer 37. Compared with the overlapping arrangement, this is conducive to improving the sensitivity of the pressure sensor 34. It can be understood that since the capacitive sensor 33 and the pressure sensor 34 are arranged in a non-overlapping manner in this exemplary embodiment, there is no need to set the pressure transmission plate 35.
[0066] Figure 7 The third exemplary embodiment of the operating handle of the medical device is shown in the cross-sectional view, and the cutting direction is the same as that of the operating handle of the medical device. Figure 1 The operating handle of this exemplary embodiment is the same as Figure 1 The illustrated joystick differs in that the sensor unit 30 .
[0067] like Figure 7 As shown, in this exemplary embodiment, the sensing unit 30 includes a capacitive sensor 33 and a pressure sensor 34. The capacitive sensor 33 is a conductive coating attached to the inner surface of the handle body 10. The conductive coating is, for example, an antimony tin oxide thin film coating, which, for example, covers the entire inner surface of the handle body 10. The pressure sensor 34 is attached to the capacitive sensor 33. This helps to reduce costs.
[0068] Figure 8 2 is a cross-sectional view for illustrating a fourth exemplary embodiment of a manipulation handle of a medical device, wherein the cutting direction is the same as that of Figure 1 The operating handle of this exemplary embodiment is the same as Figure 7 The differences between the joysticks shown are described below.
[0069] like Figure 8 As shown, in this exemplary embodiment, the sensing unit 30 further includes a pressure transmission rod 36. One end of the pressure transmission rod 36 is inserted into the inner cavity of the handle body 10. The pressure sensor 34 is not attached to the capacitive sensor 33, but is disposed at the other end of the pressure transmission rod 36. The pressure transmission rod 36 can transmit the pressure received by the sensing area 11 to the end where the pressure sensor 34 is disposed, and then generate a press detection signal by squeezing the pressure sensor 34 with an external component, such as a handle seat 40 connected to the handle body 10 through the pressure transmission rod 36. In this way, the sensitivity of force detection is improved through the lever effect.
[0070] Fig. 9A cross-sectional view of a fifth exemplary embodiment of a manipulation handle for a medical device, wherein the cutting direction is the same as Figure 1 The joystick of this exemplary embodiment is the same as Figure 1 The same or similar parts of the joysticks shown are not described in detail here, and the differences are described as follows.
[0071] like Fig. 9 As shown, in the present exemplary embodiment, the operating handle further includes a photoelectric proximity sensor 38 and a temperature sensor 39. The photoelectric proximity sensor 38 is disposed on the handle body 10, and is used to detect the situation where a person or an object approaches the sensing area 11. For example, it can generate a proximity detection signal when a person or an object approaches the sensing area 11. The temperature sensor 39 is disposed on the handle body 10, and is used to detect the temperature of the sensing area 11. In this way, the accuracy of judgment can be improved by using multiple sensing methods. For example, when a touch detection signal, a press detection signal, and a proximity detection signal are generated at the same time and the temperature of the detected sensing area 11 exceeds a set threshold, it can be judged that the operation behavior belongs to a normal operation of a person. In other exemplary embodiments, the operating handle may also include one of the photoelectric proximity sensor 38 and the temperature sensor 39. It should be noted that, Fig. 9 The positions of the photoelectric proximity sensor 38 and the temperature sensor 39 are only schematically shown, and their positions can be adjusted as needed in different embodiments, for example, they can also be set on the inner surface of the handle body 10.
[0072] The utility model also provides a medical device, which in one exemplary embodiment comprises the above-mentioned operating handle. The medical device is beneficial to preventing the operating handle from being accidentally triggered and is easy to operate.
