Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more particularly to a control handle and a medical imaging system including the same. Background Technology
[0002] Medical imaging systems are often controlled via a joystick. Users adjust the device's position by moving the joystick, for example. However, the joystick can be accidentally activated, such as by a bump, which can also affect the device's movement and compromise safety. Utility Model Content
[0003] The purpose of this invention is to provide a control handle that helps to avoid control behavior caused by accidental activation.
[0004] Another objective of this invention is to provide a medical imaging system in which the control handle helps to avoid control behavior caused by accidental activation.
[0005] This utility model provides a control handle, which includes a core rod, a handle body, a pressure detection unit, and a touch detection unit. The handle body is wrapped around the outside of the core rod. The handle body includes a base and a mounting base detachably connected to the base. The base is movably sleeved on the core rod along its length and in the opposite direction. The pressure detection unit is disposed on the core rod. The handle body can move along its length until it presses against the pressure detection unit, thereby triggering the pressure detection unit to generate a signal. The touch detection unit is disposed on the mounting base. Touching the outer surface of the handle body can trigger the touch detection unit to generate a signal.
[0006] This control handle helps prevent control actions caused by accidental activation. Furthermore, since the mounting base is detachably connected to the base, the touch detection unit can be assembled with the mounting base first, and then with the base during manufacturing. This reduces the assembly difficulty of the control handle, improves assembly efficiency, and facilitates later maintenance.
[0007] In another illustrative embodiment of the control handle, the mounting base is tubular and fitted along its length onto the outside of the base. The handle body also includes a handle sleeve. The handle sleeve is fitted along its length onto the outside of the base and the mounting base. The mounting base has an attachment surface opposite to the inner surface of the handle sleeve. A touch detection unit is sheet-shaped and attached to the attachment surface. Touching the outer surface of the handle sleeve triggers the touch detection unit to generate a signal. This facilitates the assembly of the control handle.
[0008] In another illustrative embodiment of the control handle, the mounting base has a first protrusion and a second protrusion on the rear and front sides of the attachment surface along its length, respectively. The first and second protrusions extend from the attachment surface toward the inner surface of the handle sleeve and are interference-fitted with the inner surface of the handle sleeve to fix the relative position of the handle sleeve and the mounting base. The first and second protrusions facilitate the protection of the touch detection unit during assembly and use.
[0009] In another illustrative embodiment of the control handle, the control handle further includes a protective plate. The protective plate is disposed between the touch detection unit and the inner surface of the handle sleeve. This helps to reduce wear on the touch detection unit when the handle sleeve is fitted, and also helps to reduce the air gap between the touch detection unit and the inner surface of the handle sleeve, thereby improving the sensitivity of the sensor.
[0010] In another illustrative embodiment of the control handle, the control handle further includes a button unit. The button unit includes a push-button switch mounted on the base and a key shell embedded in the handle sleeve. Pressing the key shell triggers the push-button switch to generate a switching signal. The button unit facilitates the expansion of the control functions of the control handle.
[0011] In another illustrative embodiment of the control handle, the base includes a main body and several support ribs. The main body is cylindrical, extending along its length. The main body is movably fitted onto the core rod along its length and in the opposite direction. A mounting seat is fitted onto the rear end of the main body along its length. Several support ribs protrude from the circumferential outer surface of the main body and extend along its length. Several support ribs are located on the front side of the mounting seat along its length and can support the mounting seat in the opposite direction along its length. Several support ribs are arranged circumferentially around the main body. The base forms a receiving space between every two adjacent support ribs. A push-button switch is disposed in the receiving space. The support ribs are interference-fitted with the inner surface of the handle sleeve to fix the relative position of the handle sleeve and the base. This allows for a more compact overall product structure.
[0012] In another illustrative embodiment of the control handle, the rear end of the mounting base along its length has a through-cut in the opposite direction of the length. The touch detection unit includes a first flexible circuit board and a capacitive sensor disposed within the first flexible circuit board. The first flexible circuit board includes a first functional area, a second functional area, and a connection area. The first functional area is attached to an attachment surface. The capacitive sensor is disposed in the first functional area. The second functional area is attached to the inner surface of the mounting base. The control handle also includes a processing chip. The processing chip is mounted in the second functional area. The processing chip is connected to the capacitive sensor via circuitry on the first flexible circuit board. The connection area spans the through-cut and connects the first and second functional areas. This shortens the distance between the processing chip and the capacitive sensor, thus reducing signal interference.
[0013] In another illustrative embodiment of the control handle, the front end of the core rod along its length is used to connect to the control panel. The rear end of the core rod along its length is located within the handle body and connected to the press detection unit. The core rod has a channel extending along its length. The control handle also includes a set of wires passing through the channel. The set of wires connects the press detection unit and the touch detection unit. This facilitates wiring.
[0014] In another illustrative embodiment of the control handle, the pressure detection unit includes a micro switch. The handle sleeve is closed at its rear end along its length. The handle body presses against the micro switch through the end wall of the rear end of the handle sleeve along its length, thereby triggering the micro switch to generate a signal. This facilitates a compact overall structure.
[0015] In another illustrative embodiment of the control handle, the control handle further includes a compression spring sleeved on the core rod. The compression spring can push the handle body to move relative to the core rod in the opposite direction along its length through an elastic restoring force. This allows the handle body to automatically return to its original position when not pressed.
[0016] This invention also provides a medical imaging system, which includes a control panel and the aforementioned control handle. The front end of the core rod along its length is pivotally connected to the control panel. The control handle of this medical imaging system helps to avoid control actions caused by accidental activation. Furthermore, since the mounting base is detachably connected to the base, the touch detection unit can be assembled with the mounting base first, and then with the base during manufacturing. This reduces the assembly difficulty of the control handle, improves assembly efficiency, and facilitates later maintenance.
[0017] In another illustrative embodiment of the medical imaging system, the medical imaging system is a C-arm X-ray imaging system. Attached Figure Description

[0062] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.
[0063] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.
[0064] In this document, terms such as "first" and "second" do not indicate their importance or order, but are only used to distinguish them to facilitate the description of the document.
[0065] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.
[0066] Figure 1 A perspective view illustrating one embodiment of the control handle. Figure 2 and Figure 3 for Figure 1 An exploded view of the control handle is shown. Figure 4 for Figure 1The diagram shows a partial cross-sectional view of a control handle. This control handle, for example, is part of a medical imaging system used to control equipment within the system, such as a C-arm X-ray imaging device. Examples include, but are not limited to, a digital subtraction angiography (DSA) machine or a mobile C-arm X-ray imaging device. The control handle can also be used to operate other medical devices. When applied to a medical imaging system, the control handle is, for example, pivotally mounted on the system's control panel, allowing the user to control the equipment by pivoting the handle. During use, the pivoting action received by the control handle may originate from normal human operation or from accidental triggering.
[0067] like Figures 1 to 4 As shown, the control handle 100 includes a core rod 10, a handle body 20, a press detection unit 60, and a touch detection unit 70. In use, the handle body 20 is held by the user.
[0068] like Figure 1 As shown, the handle body 20 is wrapped around the outside of the core rod 10. Figure 2 and Figure 3 As shown, the handle body 20 includes a handle sleeve 50, a base 30, and a mounting base 40. The base 30 is movably fitted onto the core rod 10 along its length L and in the opposite direction of the length L. The mounting base 40 is detachably connected to the base 30. The handle sleeve 50 is fitted onto the outside of the base 30 and the mounting base 40 along its length L. The handle body 20 is capable of moving as a whole relative to the core rod 10 along its length L and in the opposite direction of the length L.
[0069] like Figures 2 to 4 As shown, the pressure detection unit 60 is disposed on the core rod 10. Figure 5 for Figure 4 The diagram shows the changing states of the control handle. (See diagram for example.) Figure 4 and Figure 5 As shown, the handle body 20 can be extended along the length direction L by... Figure 4 Move to the position shown Figure 5 The location shown is in Figure 5 The handle body 20 at the indicated position presses against the press detection unit 60, thereby triggering the press detection unit 60 to generate a signal.
[0070] Specifically, in this illustrative embodiment, the press detection unit 60 includes a micro switch 61. For example... Figure 4 and Figure 5 As shown, the rear end of the handle sleeve 50 along the length direction L (i.e. Figure 4 and Figure 5The upper end of the handle sleeve 50 is closed. The handle body 20 presses against the micro switch 61 through a protrusion on the end wall of the rear end of the handle sleeve 50 along the length direction L, thereby triggering the micro switch 61 to generate a signal. This structure is relatively compact. In this illustrative embodiment, the pressure detection unit 60 is provided with two micro switches 61, but it is not limited to this. In other illustrative embodiments, the number of micro switches 61 in the pressure detection unit 60 can be adjusted as needed, or the micro switches can be replaced with other pressure detection mechanisms.
[0071] like Figures 2 to 4 As shown, the touch detection unit 70 is disposed on the mounting base 40. The outer surface of the touch handle body 20 can trigger the touch detection unit 70 to generate a signal. For distinction, we refer to the signal generated by the touch detection unit 70 as the touch detection signal and the signal generated by the press detection unit 60 as the press detection signal.
[0072] In this way, a press detection signal is generated when the user presses the handle body 20 along its length L; a touch detection signal is generated when the user touches the outer surface of the handle body 20. During the judgment process, for example, if either a press or touch detection signal is generated, the operation is determined to be a normal operation by the user, rather than an accidental touch. In this case, the operation is valid, meaning control of the device can be achieved. If neither a press nor touch detection signal is generated, the operation is determined to be an accidental touch. In this case, the operation is invalid, meaning control of the device cannot be achieved. This helps to avoid control actions caused by accidental touches. Furthermore, this design also caters to the habits of different users; for example, some users prefer to press the handle body 20, while others prefer to touch its outer surface, thereby improving the usability of the control handle.
[0073] Of course, in making this judgment, for example, if both pressure and touch detection signals are generated simultaneously, the operation can be determined to be a normal operation by the user, rather than an accidental trigger; if neither pressure nor touch detection signals are generated simultaneously, the operation can be determined to be an accidental trigger. This helps to further avoid control actions caused by accidental triggers. The above judgment can be achieved, for example, through the control device of the medical imaging system or a control component independent of the medical imaging system.
[0074] Furthermore, since the mounting base 40 is detachably connected to the base 30, the touch detection unit 70 can be assembled with the mounting base 40 and then with the base 30 during processing. This helps reduce the assembly difficulty of the control handle, improves assembly efficiency, and facilitates later maintenance.
[0075] Figure 6 This is an exploded view of the base and assembly. (See attached image.) Figure 6As shown, in the schematic embodiment, the mounting base 40 is tubular and fits onto the outer side of the base 30 along its length L. The mounting base 40 has an attachment surface 43 opposite to the inner surface of the handle sleeve 50. Figure 3 and Figure 4 As shown, the touch detection unit 70 is sheet-shaped and attached to the attachment surface 43. The outer surface of the touch handle sleeve 50 can trigger the touch detection unit 70 to generate a signal. It is understood that, depending on assembly requirements, an appropriate distance can be maintained between the inner surface of the handle sleeve 50 and the touch detection unit 70; this distance should meet the requirements for detection sensitivity. During handle assembly, for example, the touch detection unit 70 is first attached to the attachment surface 43 of the mounting base 40, then the mounting base 40 with the touch detection unit 70 attached is installed on the base 30, and finally the handle sleeve 50 is fitted. This facilitates the assembly of the handle.
[0076] like Figure 3 and Figure 4 As shown, in the illustrative embodiment, the mounting base 40 has a first protruding edge 41 and a second protruding edge 42 respectively provided on the rear and front sides of the attachment surface 43 along the length direction L. In this illustrative embodiment, in order to meet the requirements of cooperation with other structures, the second protruding edge 42 is divided into multiple segments, but it is not limited to this. In other illustrative embodiments, the second protruding edge 42 can also be continuous. Figure 4 and Figure 5 As shown, the first protrusion 41 and the second protrusion 42 protrude from the attachment surface 43 toward the inner surface of the handle sleeve 50 and are interference-fitted with the inner surface of the handle sleeve 50 to fix the relative position of the handle sleeve 50 and the mounting base 40. The first protrusion 41 and the second protrusion 42 are provided to protect the touch detection unit 70 during assembly and use.
[0077] like Figures 2 to 4 As shown in the illustrative embodiment, the control handle also includes a protective sheet 81. The protective sheet 81 is disposed between the inner surfaces of the touch detection unit 70 and the handle sleeve 50. This helps to reduce wear on the touch detection unit 70 when the handle sleeve 50 is fitted, and also helps to reduce the air gap between the touch detection unit 70 and the inner surface of the handle sleeve 50, thereby improving the sensitivity of the sensor.
[0078] like Figure 2 and Figure 4As shown in the illustrative embodiment, the control handle also includes a button unit 90. The button unit 90 includes a push-button switch 91 mounted on the base 30 and a key shell 92 embedded in the handle sleeve 50. Pressing the key shell 92 triggers the push-button switch 91 to generate a switching signal. The push-button switch 91 may be a microswitch, but is not limited to this. The key shell 92, for example, is inserted into the handle sleeve 50 and is made of an elastically deformable material. In other illustrative embodiments, the number and distribution of the push-button switches 91 and key shells 92 can be adjusted as needed. The button unit 90 facilitates the expansion of the control functions of the control handle.
[0079] like Figure 2 and Figure 3 As shown, the button unit 90 may also include a second flexible circuit board 93 attached to the surface of the base 30. The button switch 91 is connected to the second flexible circuit board 93, and is electrically connected to other electrical components through the circuitry in the second flexible circuit board 93. This allows for a more compact overall structure.
[0080] like Figure 6 As shown, in the illustrative embodiment, the base 30 includes a main body 31 and four supporting ribs 32. Figure 6 Only three supporting ribs 32 are visible in the middle. The main body 31 is columnar, extending along the length direction L. The main body 31 is movably fitted onto the core rod 10 along the length direction L and in the opposite direction of the length direction L. The mounting base 40 is fitted onto the rear end of the main body 31 along the length direction L (i.e., Figure 6 (The upper end of the middle). Four support ribs 32 protrude from the circumferential outer surface of the main body 31 and extend along the length direction L. The four support ribs 32 are located on the front side of the mounting base 40 along the length direction L and can support the mounting base 40 in the opposite direction of the length direction L. The four support ribs 32 are arranged around the main body 31 circumferentially. The base 30 forms a receiving space R between each pair of adjacent support ribs 32. Figure 4 As shown, the push-button switch 91 is disposed in the receiving space R. The support rib 32 is interference-fitted with the inner surface of the handle sleeve 50 to fix the relative position of the handle sleeve 50 and the base 30. This allows for a more compact overall structure of the product.
[0081] like Figure 3 As shown, in the schematic embodiment, the rear end of the mounting base 40 along the length direction L is provided with a cutout 44 that extends in the opposite direction of the length direction L. Figure 7 The deployed state of the touch detection unit is displayed. For example... Figure 7 As shown, the touch detection unit 70 includes a first flexible circuit board 71 and five capacitive sensors 72 disposed within the first flexible circuit board 71. The outer surface of the touch handle body 20 can trigger the capacitive sensors 72 to generate signals. This facilitates assembly and saves space.
[0082] like Figure 7 As shown, the first flexible circuit board 71 includes a first functional area 711, a second functional area 712, and a connection area 713. The first functional area 711 is attached to the attachment surface 43. A capacitive sensor 72 is disposed in the first functional area 711. The second functional area 712 is attached to the inner surface of the mounting base 40. The operating handle also includes a processing chip 82. The processing chip 82 is mounted in the second functional area 712. The processing chip 82 is connected to the capacitive sensor 72 via the circuitry of the first flexible circuit board 71. The processing chip 82 can, for example, be used to process the signal generated by the capacitive sensor 72. The connection area 713 spans the cutout 44 and connects the first functional area 711 and the second functional area 712. This shortens the distance between the processing chip and the capacitive sensor, which helps reduce signal interference. The capacitive sensor 72 is, for example, a rounded-end rectangular shape, which makes the electric field distribution more uniform and helps improve sensing stability.
[0083] The layout of the capacitive sensor 72 is designed, for example, according to the shape of the handle sleeve 50. Figure 8 This is a top view of the handle sleeve; specifically, in this illustrative embodiment, as shown... Figure 8 As shown, the circumferential outer surface of the handle sleeve 50 includes four continuously arranged operating surfaces 51 along its circumference. The four operating surfaces 51 are opposite to each other in pairs. For ease of understanding, Figure 8 Adjacent operating surfaces 51 are separated by dotted lines. The handle sleeve 50 has raised ridges between adjacent operating surfaces 51, allowing the user to easily determine the position of each operating surface 51 by touch during blind operation. Each operating surface 51 is equipped with, for example, an independent capacitive sensor 72 or a group of capacitive sensors 72, to generate a signal when the corresponding operating surface 51 is touched.
[0084] During the judgment process, for example, if the capacitive sensors 72 corresponding to both opposite operating surfaces 51 generate touch detection signals, the operation is judged to be a normal operation by the user. In this way, the user can make the operation valid by pinching the opposite operating surfaces 51 with their fingers, thereby improving operability. The above judgment can be achieved, for example, through the control device of the medical imaging system or a control component independent of the medical imaging system.
[0085] like Figure 8 As shown in the illustrative embodiment, two opposing operating surfaces 51 are planar, while the other two opposing operating surfaces 51 are curved. This allows users to easily distinguish between different operating surfaces by touch during blind operation, thereby improving ease of use.
[0086] In other illustrative embodiments, the shape of the outer surface of the handle sleeve 50 can be adjusted as needed, and the number and layout of the capacitive sensors 72 can also be adjusted as needed.
[0087] like Figure 4 As shown, in the illustrative embodiment, the front end of the core rod 10 along the length direction L (i.e. Figure 4 The lower end of the core rod 10 is used to connect to the control panel. The rear end of the core rod 10 along its length L (i.e., Figure 4 The upper end of the core rod 10 is located within the handle body 20 and connected to the press detection unit 60. The core rod 10 has a channel 11 extending along the length direction L. The operating handle also includes a set of wires 83 passing through the channel 11. One end of these wires 83 is connected to the press detection unit 60, the touch detection unit 70, and the button unit 90. In this illustrative embodiment, these wires 83 are indirectly connected to the touch detection unit 70 and the button unit 90, for example, by connecting the first flexible circuit board 71 and the second flexible circuit board 93. This facilitates wiring.
[0088] In an illustrative embodiment, the control handle is provided with an LED light, for example, inside the key case 92 or the base 30, and the light emitted by the LED light can be seen by the user through the key case 92 or the base 30. One end of the wire 83 is also connected to the LED light, for example.
[0089] like Figure 4 and Figure 5 As shown in the illustrative embodiment, the operating handle also includes a compression spring 84 sleeved on the core rod 10. The upper end of the compression spring 84 abuts against the handle body 20, and the lower end abuts against an annular washer fixed on the core rod 10. The compression spring 84 can push the handle body 20 to move relative to the core rod 10 in the opposite direction of its length L through elastic restoring force. This facilitates the automatic reset of the handle body when it is not pressed.
[0090] Figure 9 This is a schematic diagram illustrating one embodiment of a medical imaging system. Figure 9 As shown, the medical imaging system includes a medical imaging device 300, a control panel 200, and Figure 1 The operating handle 100 is shown. The front end of the core rod 10 along the length direction L (i.e. Figure 1 The lower end of the core rod 10 is swayably connected to the control panel 200. Specifically, the front end of the core rod 10 along the length direction L has, for example, a spherical structure and forms a spherical pair with the control panel 200 to achieve a rotatable connection, but is not limited thereto.
[0091] The medical imaging device 300 is, for example, a C-arm X-ray imaging device, such as a digital subtraction angiography (DSA) machine. In other illustrative embodiments, it may also be a mobile C-arm X-ray imaging device, but is not limited thereto. It is readily understood that when the medical imaging device 300 is a C-arm X-ray imaging device, the medical imaging system is a C-arm X-ray imaging system. The control handle 100 is used, for example, to control the medical imaging device 300, or to control other devices within the medical imaging system, such as a medical bed, a monitor, etc. During use, the user can control the medical imaging device 300 or other devices, for example, by swinging the control handle 100 relative to the control panel 200. In other illustrative embodiments, the number of control handles 100 can be adjusted as needed. The control handles of this medical imaging system help avoid control actions caused by accidental touches. Furthermore, since the mounting base 40 is detachably connected to the base 30, the touch detection unit 70 can be assembled with the mounting base 40 and then with the base 30 during manufacturing. This reduces the assembly difficulty of the control handle, improves assembly efficiency, and facilitates later maintenance.
[0092] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0093] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent implementation schemes or modifications made without departing from the spirit of the present utility model, such as combinations, divisions or repetitions of features, should be included within the scope of protection of the present utility model.
