Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an ultrasonic diagnostic and therapeutic device and a driver for an ultrasonic diagnostic and therapeutic device. Background Art

[0002] For medical devices such as ultrasonic diagnostic and therapeutic devices, they usually include a probe and a driver, and the driver can control the rotation of the probe.

[0003] The outside of the probe is often provided with a probe connector. The driver includes a bracket and a power source. The power source is located inside the bracket. The probe connector and the bracket are detachably connected. When the probe connector and the bracket are connected, the power source and the probe are connected, and the power source can control the rotation of the probe.

[0004] In the prior art, to ensure the reliable connection between the probe and the power source, a detection device for detecting the end face position of the probe connector is provided inside the bracket. The detection device is often arranged at a position where the probe and the power source can just be connected. When the detection device detects that the end face of the probe connector is in a specific position, although the power source and the probe are indeed connected at this time, there is still a certain distance that the probe connector can move relative to the bracket. At this time, the connection between the probe connector and the bracket is not reliable, which will increase the probability of accidents.

[0005] In summary, how to ensure the reliable connection between the probe connector and the driver is a technical problem that those skilled in the art need to consider. Summary of the Invention

[0006] The purpose of the present invention is to provide an ultrasonic diagnostic and therapeutic device and a driver for an ultrasonic diagnostic and therapeutic device, which can accurately obtain the in-place states of the probe connector and the driver, and further ensure the reliable connection between the probe connector and the driver.

[0007] To achieve the above purpose, an embodiment of the present invention provides a driver for an ultrasonic diagnostic and therapeutic device, including a bracket in a ring shape for the end of the probe connector to be inserted. The bracket has a chute through which a convex portion of the probe connector can pass. A locking device and a trigger switch are arranged in the chute. When the convex portion moves to the locking position in the chute, the locking device limits the convex portion at the locking position, and the trigger switch sends out a probe-in-place signal.

[0008] Optionally, the locking device and the trigger switch are arranged in sequence along the direction from the inlet end to the termination end of the chute.

[0009] Optionally, the chute includes a docking groove and a locking groove. The docking groove extends axially from the end face of the bracket, and the locking groove communicates with the docking groove and extends circumferentially. The locking device and the trigger switch are located in the locking groove.

[0010] Optionally, the locking device includes an elastic retaining arm extending from the circumferential outer side of the bracket into the sliding groove. The elastic retaining arm is provided with a protrusion towards the circumferential inner side of the bracket. The protrusion can push the elastic retaining arm to deform so as to enter or disengage from the locking position.

[0011] Optionally, the elastic retaining arm is connected to a substrate, and the substrate is fixedly arranged on the circumferential outer part of the bracket; the circuit board is connected to the trigger switch, and the substrate is connected with a pressing plate for pressing and attaching the circuit board to the circumferential outer part of the bracket.

[0012] Optionally, the substrate is connected with a fixing plate. The pressing plate, the locking device and the fixing plate are arranged on the same side of the substrate, and the pressing plate is arranged between the elastic retaining arm and the fixing plate.

[0013] Optionally, there is a bending angle between the substrate and the fixing plate.

[0014] Optionally, the trigger switch includes a dial for the protrusion to abut against and a switch body connected to the dial.

[0015] Optionally, the end of the termination of the sliding groove has a through hole or a blind hole capable of accommodating the switch body.

[0016] An ultrasonic diagnosis and treatment device provided by an embodiment of the present invention further includes a probe connector having a protrusion, and further includes a driver as described above for connecting to the probe connector.

[0017] Compared with the above background art, the driver for an ultrasonic diagnosis and treatment device provided by an embodiment of the present invention includes a bracket having a sliding groove, and a locking device and a trigger switch are arranged in the sliding groove.

[0018] Regarding the connection process of the driver and the probe connector, it can be generally summarized as follows: Insert the end of the probe connector into the bracket, and the protrusion of the probe connector moves along the sliding groove. When the protrusion slides to the locking position of the sliding groove, the locking device limits the protrusion at the locking position, and the trigger switch sends out a signal that the probe is in place, that is, the relative position of the probe connector and the bracket is fixed, and the connection between the probe connector and the driver is reliable.

[0019] The beneficial effects of the above driver mainly include the following aspects:

[0020] First, considering that the trigger switch is fixed relative to the sliding groove, the trigger switch is used to feedback in real time whether the protruding part is in the locking position of the sliding groove. Only when the protruding part is located in the locking position of the sliding groove, the trigger switch will be triggered, and then the trigger switch emits a probe-in-place signal. In this way, the setting method of only detecting the end face position of the probe connector in the prior art is abandoned. In this article, once the protruding part leaves the locking position of the sliding groove, the untriggered trigger switch will not emit a probe-in-place signal. Although the current driver and the probe connector may still remain connected, at this time, it can be detected that the driver and the probe connector are in a state where they may be disconnected, thereby reducing the probability of accidents.

[0021] Second, as can be seen from the above, since the trigger switch is set at the locking position in the sliding groove, during the connection process of the driver and the probe connector, the protruding part will never come into contact with the trigger switch until the moment when the protruding part moves to the locking position, the trigger switch will be triggered. The setting of the trigger switch will not hinder the sliding process of the protruding part in the sliding groove, and the connection process of the driver is convenient and reliable.

[0022] Third, by using the locking device to limit the position of the protruding part, it is possible to further prevent the protruding part from leaving the locking position, thereby ensuring the relative position of the probe connector and the bracket is fixed, and realizing the reliable connection between the probe connector and the driver. It can be seen that when the protruding part moves to the locking position, two different actions will be triggered. The first is that the locking device limits the position of the protruding part, and the second is that the trigger switch emits a probe-in-place signal. That is, on the premise of accurately knowing the in-place state of the probe connector and the driver through the probe-in-place signal, it is also possible to ensure the reliable connection between the probe connector and the driver, so as to improve the reliability of the ultrasonic diagnostic and therapeutic equipment.

[0023] The embodiment of the present invention also provides an ultrasonic diagnostic and therapeutic equipment including the above-mentioned driver. The beneficial effects can be referred to the above, and will not be elaborated here. Description of the Drawings

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] To enable those skilled in the art of this technical field to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] A driver 100 for an ultrasonic diagnostic and therapeutic device provided by an embodiment of the present invention is referred to the attached drawings of the specification Figure 1 to Figure 8 . The driver 100 includes a bracket 1. The bracket 1 is annular, and the end of the probe connector 4 can be inserted into the bracket 1.

[0042] The bracket 1 has a chute 10. The chute 10 can be spiral. The inlet end of the chute 10 is located on the end face of the bracket 1, that is, the inlet end of the chute 10 is open.

[0043] A convex portion 41 is provided on the outer periphery of the probe connector 4. When the probe connector 4 is inserted into the bracket 1, the convex portion 41 enters the chute 10 from the inlet end of the chute 10, and the convex portion 41 can move in the chute 10.

[0044] A locking device 32 and a trigger switch 21 are provided in the chute 10. When the convex portion 41 moves to the locking position of the chute 10, the locking device 32 limits the convex portion 41 at the locking position, and the trigger switch 21 emits a probe-in-place signal. At this time, it indicates that the relative positions of the probe connector 4 and the bracket 1 are fixed, that is, the connection between the probe connector 4 and the driver 100 is reliable.

[0045] Regarding the locking position in the chute 10, it should refer to the position where the probe connector 4 and the bracket 1 are connected in place, that is, the position where the convex portion 41 and the chute 10 are connected in place. When the convex portion 41 is at the locking position of the chute 10, the probe connector 4 and the bracket 1 are connected in place. Among them, the locking position can be located at the termination end of the chute 10, or can be set at other positions of the chute 10 according to actual needs.

[0046] When the probe-in-place signal is emitted, the display interface of the ultrasonic diagnostic and therapeutic device can display the information of the probe connection to the operator; when the convex portion 41 leaves the locking position of the chute 10, the trigger switch 21 stops emitting the probe-in-place signal, and the display interface displays the information that the probe is not connected to the operator.

[0047] In addition, after the trigger switch 21 emits the probe-in-place signal, the ultrasonic diagnostic and therapeutic device can also perform subsequent actions according to the probe-in-place signal. In addition to the above-mentioned display interface displaying corresponding information to the operator, actions such as controlling the rotation of the probe can also be performed; if the probe-in-place signal is not emitted by the trigger switch 21, actions such as probe rotation cannot be performed, so as to ensure the safety during use.

[0048] It can be seen that by using the trigger switch 21, it is possible to feedback whether the convex portion 41 is in the locking position of the sliding groove 10, and thus it is possible to timely know whether the probe connector 4 and the bracket 1 are connected in place, that is, it is possible to timely determine whether the probe connector 4 is in the in-position state.

[0049] Refer to the attached instructions Figure 5 As shown, the locking device 32 and the trigger switch 21 can be sequentially arranged along the direction from the inlet end of the sliding groove 10 to the termination end of the sliding groove 10.

[0050] During the connection process of the probe connector 4 and the bracket 1, that is, during the movement of the convex portion 41 from the inlet end to the termination end of the sliding groove 10, the convex portion 41 first passes through the locking device 32 and then reaches the locking position. When the convex portion 41 reaches the locking position, the trigger switch 21 issues a probe in-position signal, and the locking device 32 confines the convex portion 41 at the locking position.

[0051] For the specific setting method of the sliding groove 10, reference can also be made to the attached instructions Figure 1 and the attached Figure 3 to the attached Figure 8 , the sliding groove 10 includes a docking groove 11 and a locking groove 12. The docking groove 11 and the locking groove 12 are communicated with each other. The docking groove 11 extends axially along the end face of the bracket 1, and the locking groove 12 extends circumferentially along the bracket 1.

[0052] The docking groove 11 extends from the end face of the bracket 1, and one end of the docking groove 11 located at the end face of the bracket 1 is open, that is, the inlet end of the sliding groove 10. The inlet end of the sliding groove 10 can be set to be open, that is, one end of the docking groove 11 located at the end face of the bracket 1 is set to be open, so as to facilitate the convex portion 41 to extend into the docking groove 11.

[0053] The convex portion 41 enters the docking groove 11 from the inlet end of the sliding groove 10. When the convex portion 41 moves to the end of the docking groove 11, the probe connector 4 rotates relative to the bracket 1, so that the convex portion 41 moves from the docking groove 11 to the locking groove 12.

[0054] Among them, the docking groove 11 is not limited to being parallel to the axis of the bracket 1. While the docking groove 11 extends axially along the bracket 1, it can also have a certain angle with the axis of the bracket 1; taking the orientation shown in the attached instructions Figure 1 as an example, the docking groove 11 shown in the attached Figure 1 is parallel to the axis of the bracket 1. At this time, the docking groove 11 is vertical. If the docking groove 11 is inclined, the docking groove 11 and the axis of the bracket 1 are not parallel, but at this time, it can still be considered that the docking groove 11 extends axially along the bracket 1.

[0055] An arc groove may be provided at the connection between the docking groove 11 and the locking groove 12 to avoid stress concentration, thereby improving the structural reliability of the bracket 1. At the same time, the arc groove can also reduce the wear on the protrusion 41. The protrusion 41 can move smoothly from the docking groove 11 to the locking groove 12, making the connection process more convenient.

[0056] For the slide slot 10 including the docking slot 11 and the locking slot 12 , the trigger switch 21 and the locking device 32 should be arranged in the locking slot 12 , and the locking position should also be located in the locking slot 12 .

[0057] During the process of connecting the probe connector 4 and the bracket 1, the protrusion 41 can reach the locking position only after the protrusion 41 moves to the locking groove 12, that is, after the probe connector 4 rotates relative to the bracket 1, thereby limiting the position of the protrusion 41 and sending a probe in place signal.

[0058] It can be seen that the trigger switch 21 and the locking device 32 are arranged at the terminal end of the slide groove 10 as much as possible, and the extension directions of the docking groove 11 and the locking groove 12 are different, so as to ensure the reliable connection between the probe connector 4 and the bracket 1 to the greatest extent.

[0059] For the specific setting method of the locking device 32, please refer to the attached manual. Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 8 The locking device 32 includes an elastic blocking arm 320 provided with a protrusion 321. The elastic blocking arm 320 extends from the circumferential outer side of the bracket 1 into the slide groove 10, and the protrusion 321 is provided on the circumferential inner side of the elastic blocking arm 320 toward the bracket 1.

[0060] The elastic blocking arm 320 and the protrusion 321 may be an integral structure, for example, they may be made by stamping or the like, and the protrusion 321 may be in an arc shape.

[0061] When the protrusion 41 of the probe connector 4 moves to the locking position of the slide groove 10, the protrusion 41 will first be blocked by the protrusion 321. At this time, the protrusion 41 needs a larger thrust to push the elastic blocking arm 320 and the protrusion 321, that is, the protrusion 41 lifts the protrusion 321 to a position where it does not hinder the movement of the protrusion 41. The elastic blocking arm 320 will produce a certain elastic deformation upward, and then the protrusion 41 continues to move until the protrusion 41 reaches the locking position of the slide groove 10.

[0062] When the protrusion 321 is not pushed by the protrusion 41, the elastic blocking arm 320 and the protrusion 321 will return to the initial position under the action of the elastic force. At this time, the protrusion 321 and the protrusion 41 are in contact with each other, thereby preventing the protrusion 41 from escaping from the locking position of the slide groove 10.

[0063] When it is necessary to disconnect the connection between the bracket 1 and the probe connector 4, conversely to the above process, the protrusion 41 first pushes the elastic stop arm 320 and the protrusion 321. The elastic stop arm 320 and the protrusion 321 are lifted upward so that the protrusion 41 is disengaged from the locking position. Then, the protrusion 41 can move toward the inlet end direction of the chute 10 and finally move out of the chute 10.

[0064] It can be seen that when the protrusion 41 is in the locking position, the protrusion 41 fits against the protrusion 321. The protrusion 41 is blocked by the protrusion 321, and the protrusion 321 plays a limiting role on the protrusion 41 to fix the protrusion 41 in the locking position, so as to ensure that the position of the protrusion 41 is fixed reliably.

[0065] Meanwhile, during the process of connecting the bracket 1 and the probe connector 4, when the protrusion 41 reaches the locking position of the chute 10, the protrusion 321 returns to the initial position under the action of the elastic force. The protrusion 321 impacts the protrusion 41, generating a certain impact force. This impact force is feedback to the probe connector 4, that is, feedback the feeling of being connected in place, so that the operator can clearly know that the current connection between the bracket 1 and the probe connector 4 is in place.

[0066] Of course, for the specific setting method of the locking device 32, the position limitation of the protrusion 41 can also be realized by using the magnetic adsorption method.

[0067] For example, the locking device 32 can be specifically a first adsorption component arranged at the locking position, and a second adsorption component is arranged on one side of the protrusion 41 facing the locking position. The first adsorption component and the second adsorption component can adsorb each other.

[0068] The first adsorption component can be specifically an N - pole magnet, and the second adsorption component can be specifically an S - pole magnet. When the protrusion 41 is in the locking position, there is an adsorption force between the first adsorption component and the second adsorption component to limit the protrusion 41 at the locking position of the chute 10.

[0069] In addition, the above - mentioned first adsorption component and second adsorption component can also be other components outside the locking device 32. That is, on the premise that the elastic stop arm 320 is provided on the driver 100, the first adsorption component and the second adsorption component are also provided to further ensure the relative position fixation between the bracket 1 and the protrusion 41.

[0070] Refer to the attached Figure 1 and attached Figure 2 As shown, a base plate 30 is fixedly connected to the circumferential outside of the bracket 1. The base plate 30 is connected to the elastic stop arm 320. The base plate 30 and the elastic stop arm 320 can be integrally formed and processed by using a metal plate or an injection - molded part.

[0071] Combined with the attached Figure 4 and attachedFigure 7 On the surface of the bracket 1, a plane 17 can also be provided, and the substrate 30 is attached to the plane 17. Since the positions of the substrate 30 and the bracket 1 are fixed, the elastic retaining arm 320 can be fixed relative to the bracket 1.

[0072] A circuit board 2 is provided outside the bracket 1. The trigger switch 21 is connected to the circuit board 2. On the surface of the bracket 1, an installation surface 15 can also be provided, and the circuit board 2 is placed on the installation surface 15. The installation surface 15 can also be provided with positioning posts 18, and the circuit board 2 is provided with positioning holes that cooperate with the positioning posts 18. When the positioning posts 18 extend into the positioning holes, the relative positions of the circuit board 2 and the circuit board 2 are fixed.

[0073] The substrate 30 is connected to a pressing plate 31. The pressing plate 31 should be able to withstand a certain amount of elastic deformation and can specifically be made of metal or plastic. Taking the orientation shown in the attached drawings of the specification as an example, the pressing plate 31 presses above the circuit board 2. The pressing plate 31 always has a tendency to move downward, so that the part of the circuit board 2 where the trigger switch 21 is not provided is in contact with the installation surface 15, and the trigger switch 21 is located in the sliding groove 10. Figure 1 As shown in the attached drawings of the specification, the substrate 30, the pressing plate 31, and the locking device 32 can be regarded as partial structures of the elastic piece 3. The pressing plate 31 and the elastic retaining arm 320 are connected by the substrate 30. The substrate 30 can also be connected to a fixing plate 33. On the surface of the bracket 1, a fixing surface 16 is provided, and the fixing plate 33 is connected to the fixing surface 16.

[0074] Combined with the attached drawings of the specification Figure 2 As shown, the substrate 30, the pressing plate 31, and the locking device 32 can be regarded as partial structures of the elastic piece 3. The pressing plate 31 and the elastic retaining arm 320 are connected by the substrate 30. The substrate 30 can also be connected to a fixing plate 33. On the surface of the bracket 1, a fixing surface 16 is provided, and the fixing plate 33 is connected to the fixing surface 16.

[0075] The elastic piece 3 can be integrally formed and made by processing methods such as stamping and cutting to ensure the overall structure of the elastic piece 3 is stable and reliable. There can be a certain bending angle between the substrate 30 and the fixing plate 33, so the plane 17 and the fixing surface 16 of the bracket 1 should also be at an angle, so that the substrate 30 fits with the plane 17 and the fixing plate 33 fits with the fixing surface 16.

[0076] The advantage of this setting is that the height space of the bracket 1 can be fully utilized, avoiding excessive occupation of the surface area of the bracket 1 by the elastic piece 3, and the contact surfaces between the elastic piece 3 and the bracket 1 are located at different orientations, which helps to improve the connection reliability between the two.

[0077] The fixing plate 33 can also be provided with mounting holes 331, and the fixing surface 16 is provided with assembly holes coaxial with the mounting holes 331. Fasteners such as bolts can be used to pass through the mounting holes 331 and the assembly holes to fix the fixing plate 33 to the fixing surface 16. In addition, based on the fact that the substrate 30 fits with the plane 17, this can ensure the most reliable installation of the elastic piece 3 and the bracket 1 to enable the pressing plate 31 and the elastic retaining arm 320 to respectively achieve the above different technical effects.

[0078] More preferably, as shown in the attached drawings of the specificationFigure 2 As shown, the pressing plate 31, the elastic retaining arm 320, and the fixing plate 33 are all connected to one side of the substrate 30, and the pressing plate 31 is disposed between the elastic retaining arm 320 and the fixing plate 33.

[0079] In this way, the substrate 30 and the fixing plate 33, as the connecting parts of the elastic piece 3 and the bracket 1, can be disposed at a position away from the locking groove 12, so that the structure of the elastic piece 3 is reasonable and reliable; at the same time, the substrate 30 can also effectively withstand the acting forces exerted by the pressing plate 31 and the elastic retaining arm 320 from the protruding portion 41, avoiding large displacements of the pressing plate 31 and the elastic retaining arm 320 due to the acting force of the protruding portion 41, and further ensuring the reliable use of the driver 100.

[0080] In addition to installing the trigger switch 21 on the circuit board 2 described above, fasteners such as bolts in the prior art can also be used to install the trigger switch 21 in the locking groove 12. In addition, the trigger switch 21 can also be directly fixed in the locking groove 12 by means of pasting or the like.

[0081] Regarding the specific structure of the trigger switch 21, a contact type or non-contact type switch can be adopted. Specifically, for the contact type trigger switch 21, when the protruding portion 41 is in the locked position in the locking groove 12, the protruding portion 41 touches the trigger switch 21, and the trigger switch 21 emits a probe-in-place signal. For the non-contact type trigger switch 21, when the protruding portion 41 is in the locked position in the locking groove 12, the trigger switch 21 can use light sensing elements such as infrared rays to detect the protruding portion 41, and then the trigger switch 21 emits a probe-in-place signal.

[0082] For the contact type trigger switch 21, referring to the attached Figure 5 description, the trigger switch 21 may include a switch body 210 and a dial 211. The switch body 210 and the dial 211 are connected. The dial 211 is used for the protruding portion 41 to abut against, and the switch body 210 is used for emitting a probe-in-place signal. The protruding portion 41 is located at a position where it can abut against the dial 211 to cause the switch body 210 to emit a probe-in-place signal, that is, the trigger position of the contact type trigger switch 21. Similarly, the non-contact switch such as a light sensing element also has a trigger position, which can be triggered when the protruding portion 41 falls within the sensing range.

[0083] Combined with the above, when the protruding portion 41 moves to the locked position of the locking groove 12, the protruding portion 41 and the dial 211 are in direct contact, and the switch body 210 can emit a probe-in-place signal; obviously, the dial 211 should be disposed at the locked position of the locking groove 12. When the protruding portion 41 is in the locked position, it will inevitably contact the dial 211 located at the locked position, thereby causing the switch body 210 to emit a probe-in-place signal.

[0084] When the convex part 41 reaches the locking position of the sliding groove 10, both the dial 211 and the protrusion 321 are attached to both sides of the convex part 41, that is, both the dial 211 and the protrusion 321 clamp the convex part 41 in the middle. And since the positions of both the dial 211 and the protrusion 321 are fixed, the convex part 41 is limited in both movement directions, thereby enhancing the position-limiting effect on the convex part 41.

[0085] Furthermore, for the trigger switch 21 including the switch body 210 and the dial 211, the specific structure of the sliding groove 10 can also be adaptively set.

[0086] Reference can be made to the appended Figure 3 to the appended Figure 8 , the end of the locking groove 12 facing away from the docking groove 11 has a through hole 13 or a blind hole 14. The appended Figure 3 to the appended Figure 5 shows the case where the locking groove 12 has a through hole 13. The appended Figure 6 to the appended Figure 8 shows the case where the locking groove 12 has a blind hole 14.

[0087] If the locking groove 12 has a blind hole 14, the trigger switch 21 can be placed in the blind hole 14. In this way, the blind hole 14 plays a supporting role for the trigger switch 21, thereby facilitating the installation of the trigger switch 21 and preventing the trigger switch 21 from falling to other positions. For the above-mentioned trigger switch 21 including the switch body 210 and the dial 211, the switch body 210 should be placed in the blind hole 14, while the dial 211 should be located outside the blind hole 14 for the convex part 41 to touch, as shown in the appended Figure 8 .

[0088] If the locking groove 12 has a through hole 13, the trigger switch 21 can be placed in the through hole 13, and the trigger switch 21 and the side wall of the through hole 13 can be fixed by fitting. In this way, space can be saved. For the above-mentioned trigger switch 21 including the switch body 210 and the dial 211, both the switch body 210 and the dial 211 should be placed in the blind hole 14 for the convex part 41 to touch, as shown in the appended Figure 5 .

[0089] Since the trigger switch 21 is located in the locking groove 12, it can be considered that at least part of the locking groove 12 is blocked by the circuit board 2, and based on the above-mentioned connection between the circuit board 2 and the mounting surface 15, the trigger switch 21 can be fixed relative to the position of the locking groove 12.

[0090] It can be seen that whether the locking groove 12 has a through hole 13 or a blind hole 14, since the trigger switch 21 is connected to the circuit board 2 and the position of the circuit board 2 and the mounting surface 15 is fixed, the position of the trigger switch 21 and the locking groove 12 can be ensured to be fixed.
