Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device and auxiliary system for a remote ultrasound diagnostic instrument. Background Technology

[0002] In the current medical context, medical experts are scarce, while patients are scattered across the country, often separated by long distances. Under the current circumstances, diagnosis can only be carried out through long-distance meetings between patients or experts, or through remote video. Long-distance meetings are inefficient and cause significant strain on patients or experts, while remote video has extremely high limitations. For example, when ultrasound diagnosis is required, it is difficult for experts to adjust the ultrasound probe in real time to obtain information about the lesion from different angles. Therefore, it is difficult to achieve remote ultrasound diagnosis under current technology. Furthermore, existing button and knob devices are difficult to synchronize in remote diagnostic systems. When the expert adjusts the device, the patient's device needs to be adjusted synchronously. Conversely, when the patient's assistant doctor adjusts the device, the expert's device also needs to be adjusted synchronously. Otherwise, it is easy to cause confusion due to asynchronous settings. Existing buttons, knobs, and other devices cannot meet the above requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a device for a remote ultrasound diagnostic instrument to solve the problem of inconsistent settings that easily occur during remote diagnosis, and to propose an auxiliary system for a remote ultrasound diagnostic instrument to enable experts to perform remote ultrasound diagnosis on patients.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a control device for a remote ultrasound diagnostic instrument, comprising an outer frame, a dual-function button passing through the outer frame, and a lifting trigger disposed inside the outer frame. The dual-function button is sleeved and installed on the upper end of the lifting trigger, and the dual-function button can rotate relative to the lifting trigger. When the dual-function button moves axially, it can drive the lifting trigger to move axially synchronously. It also includes a first support seat fixedly disposed on the inner wall of the outer frame, and the lifting trigger's lifting limit is disposed inside the first support seat. The lifting trigger has a self-locking function after being pressed, and the lifting action of the lifting trigger realizes the on / off control of the button function; the lifting trigger... The lower end of the component is connected and fixed with an electromagnet. Below the electromagnet is an electromagnet unit for magnetically driving the electromagnet. Through the cooperation of the electromagnet and the electromagnet unit, the pressing force on the lifting trigger can be simulated. The outer ring tooth is fixedly provided on the outside of the dual-function button. A cylindrical gear is meshed on the outside of the outer ring tooth. When the dual-function button moves axially, it will drive the outer ring tooth to slide along the axial direction of the cylindrical gear. During the process, the outer ring tooth and the cylindrical gear always remain meshed. The end of the cylindrical gear is connected in sequence with a rotation angle sensor and a servo motor. The rotation angle sensor monitors the rotation angle of the dual-function button and actively controls the rotation of the dual-function button.

[0005] The surface of the lifting trigger is provided with a self-locking groove, and a U-shaped lock is oscillatingly mounted on the first support seat. One end of the U-shaped lock is inserted into the self-locking groove. By cooperating with the self-locking groove, the lifting trigger can be self-locked when pressed once and unlocked when pressed again.

[0006] A synchronous shaft is fixedly installed at the bottom of the lifting trigger, and the electromagnet is connected and fixed to the lifting trigger through the synchronous shaft.

[0007] A pressing spring is provided below the electronic disk, and the pressing spring applies an upward pushing force to the electronic disk.

[0008] The upper part of the dual-function button is provided with a pre-locking pressure plate that can be raised and lowered. The lower part of the pre-locking pressure plate is fixedly provided with a positioning center column. The outer surface of the positioning center column is fixedly provided with a protruding ring near the bottom. The dual-function button has a cavity inside, and a limiting ring platform is fixedly provided on the inner wall of the cavity. The positioning center column is limited and inserted through the limiting ring platform. The protruding ring is located below the limiting ring platform to limit the upward movement height of the pre-locking pressure plate. The bottom of the positioning center column is embedded with a rolling extrusion ball.

[0009] A cross plate is fixedly installed in the internal cavity of the dual-function button, and a square rod is inserted through the cross plate. The square rod has a rectangular cross-section, so that the square rod can only move up and down relative to the cross plate, but cannot rotate.

[0010] An upper support plate is fixedly installed at the upper end of the square rod. The compression ball is in compression contact with the upper support plate. A spring piece is fixedly installed on the cross plate. The spring piece applies an upward elastic thrust to the upper support plate. The elastic force provided by the spring piece is less than the elastic force provided by the pressing spring. A movable locking disc is fixedly installed at the lower end of the square rod. A matching locking groove is opened on the upper surface of the lifting trigger. When the movable locking disc moves down, it will be locked into the matching locking groove, so that the square rod and the lifting trigger cannot rotate relative to each other.

[0011] A second support seat is also fixedly installed on the inner wall of the outer frame, and the rotation angle sensor is fixedly installed in the second support seat; a friction ring is fixedly installed at the end of the cylindrical gear, and a damping pneumatic bladder is installed inside the second support seat. By changing the air pressure in the damping pneumatic bladder, the contact pressure between the damping pneumatic bladder and the friction ring is changed, thereby changing the rotational resistance of the cylindrical gear.

[0012] The second support seat has an active column cavity and an internal air passage. The end of the active column cavity is connected to the damping pneumatic bladder through the internal air passage. A piston column is provided in the active column cavity, and a return spring is provided on one side of the piston column. Through the elastic support of the return spring, the piston column tends to move outward, thereby reducing the gas pressure in the damping pneumatic bladder. A pushing protrusion is fixedly provided on the surface of the lifting trigger. When the lifting trigger is in the rising state, the pushing protrusion is in contact with the piston column, which increases the gas pressure in the damping pneumatic bladder. When the lifting trigger is in the falling state, the pushing protrusion is not in contact with the piston column, and the gas pressure in the damping pneumatic bladder decreases.

[0013] An auxiliary system for a remote ultrasound diagnostic instrument includes a control device, an expert terminal, and a patient terminal; The expert terminal operates on a mannequin, while the patient terminal operates on a real patient. The expert terminal and the patient terminal are composed of the same modules, both including a slide rail base module, a robotic arm module, a probe clip module, an ultrasound diagnostic instrument host module, and a remote system workstation; The probe clamp module is used to clamp and fix the ultrasonic probe. The probe clamp module is installed on the robotic arm module. The robotic arm module can actively control the movement of the ultrasonic probe, and can also passively detect the amount of movement based on the movement of the ultrasonic probe, so that the robotic arm module at the expert end and the robotic arm module at the patient end move synchronously. During remote diagnosis, the expert is at the expert end and performs ultrasound diagnosis on the mannequin. The expert moves the ultrasound probe at the expert end, causing the robotic arm module at the expert end to passively detect the amount of movement and send the data to the patient end. The robotic arm module at the patient end moves synchronously. When the ultrasound probe driven by the robotic arm module at the patient end comes into contact with the patient, the robotic arm module at the patient end feeds back the resistance data to the robotic arm module at the expert end, causing the robotic arm module at the expert end to generate corresponding resistance. The slide rail base module enables the robotic arm module to adjust its position along the height of the mannequin or real patient, with the slide rail base modules at the expert end and the patient end moving synchronously. The control device is installed on the main module of the ultrasound diagnostic instrument and is used to adjust the parameters of the main module of the ultrasound diagnostic instrument. The control device can perform pressing and rotating operations, and when the control device on the expert end performs a pressing or rotating operation, the control device on the patient end can automatically synchronize the operation. The remote system workstation at the expert end and the remote system workstation at the patient end are connected via network communication; The ultrasound diagnostic instrument's main unit module, robotic arm module, and slide rail base module all achieve synchronous information transmission between the expert and patient ends through a remote system workstation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The control device in this invention can simultaneously perform button and knob operation control and has a self-automatic action function. When applied in a remote diagnostic system, it can synchronize the operation settings of both ends. When one end performs a pressing or rotating operation, the other end can actively and spontaneously synchronize the pressing or rotating operation, avoiding the problem of confusion in the setting information of the two diagnostic devices.

[0015] The control device of the present invention, through the cooperation of a pre-locking pressure plate and a moving lock plate, can greatly reduce interference with the rotation angle when performing a pressing operation. This temporarily locks the rotation function during the pressing operation, reducing the risk of changes in the rotation angle of the knob due to hand shaking during the pressing process.

[0016] The control device of the present invention, through the combination of a second support seat, a damping pneumatic bladder and a pushing protrusion, can dynamically change the rotational resistance of the dual-function button. When the dual-function button is fully extended, the rotational damping of the dual-function button is increased to reduce the risk of accidental changes in rotation angle caused by accidental contact. When the dual-function button is in the retracted state, the probability of accidental contact is low. At this time, the rotational damping of the dual-function button is reduced, which makes it easier to rotate and adjust when holding the button with a small amount of force.

[0017] The auxiliary system of the remote ultrasound diagnostic instrument of this invention can synchronize the operation of the expert end and the patient end, so that the expert can realize remote ultrasound diagnosis of the patient by using the fuzzy positioning of the dummy model and the feedback resistance of the robotic arm module.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 10 This invention provides a technical solution: a control device for a remote ultrasound diagnostic instrument, comprising an outer frame 1, a dual-function button 2 passing through the outer frame 1, and a lifting trigger 3 disposed inside the outer frame 1. The dual-function button 2 is sleeved and installed on the upper end of the lifting trigger 3, and the dual-function button 2 can rotate relative to the lifting trigger 3. When the dual-function button 2 moves axially, it can drive the lifting trigger 3 to move axially synchronously. Figure 8 As shown, a bearing 212 is installed between the dual-function button 2 and the lifting trigger 3. The bearing 212 reduces the rotational resistance of the dual-function button 2 relative to the lifting trigger 3 and improves the rotational life of the dual-function button 2.

[0031] It also includes a first support seat 4 fixedly mounted on the inner wall of the outer frame 1, and a lifting trigger 3 with a lifting limit set inside the first support seat 4. The lifting trigger 3 has a self-locking function after being pressed, and the lifting action of the lifting trigger 3 realizes the on / off control of the button function, such as... Figure 9As shown, a conductive post 401 is embedded and fixed through the lifting trigger 3. The lifting trigger 3 is made of insulating material, while the conductive post 401 is made of metal conductor. A contact post 402 is inserted and installed on the surface of the first support base 4. There are two sets of contact posts 402, which are symmetrically distributed on both sides of the conductive post 401. When the lifting trigger 3 is pressed, the conductive post 401 will move down and contact the contact post 402, so that the two sets of contact posts 402 are interconnected, thereby realizing the connection of the switch function. When the lifting trigger 3 is pressed again, after unlocking and moving up to reset, the conductive post 401 will be offset from the contact post 402, thereby realizing the closing of the switch function.

[0032] The end of the contact post 402 is provided with a pressure-holding spring 403. The pressure-holding spring 403 is fixed to the outer surface of the first support base 4 by screws. The pressure-holding spring 403 applies elastic force, causing the contact post 402 to have a tendency to move towards the side where the conduction insert 401 is located. A button pin 404 is welded to the outside of the pressure-holding spring 403. The button pin 404 is used to connect the device wire.

[0033] The lower end of the lifting trigger 3 is connected and fixed with an electric disk 5. Below the electric disk 5 is an electromagnet unit 6 for magnetically driving the electric disk 5. Through the cooperation of the electric disk 5 and the electromagnet unit 6, the pressing force on the lifting trigger 3 can be simulated. The dual-function button 2 is externally fixed with an outer ring tooth 7, and a cylindrical gear 8 is externally meshed with the outer ring tooth 7. When the dual-function button 2 moves axially, it will drive the outer ring tooth 7 to slide along the axial direction of the cylindrical gear 8. During the process, the outer ring tooth 7 and the cylindrical gear 8 always remain meshed. The end of the cylindrical gear 8 is sequentially connected to a rotation angle sensor 9 and a servo motor 10. The rotation angle sensor 9 monitors the rotation angle of the dual-function button 2 and actively controls the rotation of the dual-function button 2.

[0034] The surface of the lifting trigger 3 is provided with a self-locking groove 301, and a U-shaped lock 302 is oscillatingly arranged on the first support seat 4. One end of the U-shaped lock 302 is inserted into the self-locking groove 301. By cooperating with the self-locking groove 301, the lifting trigger 3 can be self-locked when pressed once and unlocked when pressed again.

[0035] A synchronous shaft 303 is fixedly installed at the bottom of the lifting trigger 3, and the electric disk 5 is connected and fixed to the lifting trigger 3 through the synchronous shaft 303.

[0036] A pressing spring 601 is provided below the magnetic disk 5. The pressing spring 601 applies an upward pushing force to the magnetic disk 5, such as... Figure 5As shown, a spring positioning cylinder 501 is fixedly provided on the lower surface of the magnetic disk 5. The spring positioning cylinder 501 is inserted into the pressing spring 601 and is used to position and stabilize the pressing spring 601.

[0037] The upper part of the dual-function button 2 is provided with a pre-locking pressure plate 201 that can be raised and lowered. The lower part of the pre-locking pressure plate 201 is fixedly provided with a positioning center post 202. The outer surface of the positioning center post 202 is fixedly provided with a protruding ring 203 near the bottom. The internal cavity of the dual-function button 2 is provided with a limiting ring platform 204 fixedly provided on the inner wall of the cavity. The positioning center post 202 is limited to pass through the limiting ring platform 204. The protruding ring 203 is located below the limiting ring platform 204, limiting the upward movement height of the pre-locking pressure plate 201. The bottom of the positioning center post 202 is embedded with a rolling extrusion ball 205.

[0038] A cross plate 206 is fixedly installed in the internal cavity of the dual-function button 2. A square rod 207 is inserted through the cross plate 206. The square rod 207 has a rectangular cross section, so that the square rod 207 can only move up and down relative to the cross plate 206, but cannot rotate.

[0039] An upper support plate 208 is fixedly installed at the upper end of the square rod 207. The extrusion ball 205 is in extrusion contact with the upper support plate 208. A spring piece 209 is fixedly installed on the cross plate 206. The spring piece 209 applies an upward elastic thrust to the upper support plate 208. The elastic force provided by the spring piece 209 is less than the elastic force provided by the compression spring 601; A movable locking disc 210 is fixedly installed at the lower end of the square rod 207. A matching locking groove 211 is opened on the upper surface of the lifting trigger 3. When the movable locking disc 210 moves down, it will be locked into the matching locking groove 211, so that the square rod 207 and the lifting trigger 3 cannot rotate relative to each other.

[0040] A second support seat 101 is also fixedly installed on the inner wall of the outer frame 1, and the rotation angle sensor 9 is fixedly installed in the second support seat 101; A friction ring 102 is fixedly provided at the end of the cylindrical gear 8, and a damping pneumatic bladder 103 is provided inside the second support seat 101. By changing the air pressure in the damping pneumatic bladder 103, the contact pressure between the damping pneumatic bladder 103 and the friction ring 102 is changed, thereby changing the rotational resistance of the cylindrical gear 8.

[0041] The second support seat 101 has an active column cavity 104 and an internal air passage 105. The end of the active column cavity 104 is connected to the damping pneumatic bladder 103 through the internal air passage 105. A piston column 106 is provided in the active column cavity 104, and a return spring 107 is provided on one side of the piston column 106. Through the elastic support of the return spring 107, the piston column 106 tends to move outward, thereby driving the gas pressure in the damping pneumatic bladder 103 to decrease. The surface of the lifting trigger 3 is fixedly provided with a pushing protrusion 108. When the lifting trigger 3 is in the rising state, the pushing protrusion 108 is pressed and contacted with the piston column 106, which increases the gas pressure in the damping pneumatic bladder 103. When the lifting trigger 3 is in the falling state, the pushing protrusion 108 is not in contact with the piston column 106, and the gas pressure in the damping pneumatic bladder 103 decreases.

[0042] An auxiliary system for a remote ultrasound diagnostic instrument includes a control device, an expert terminal, and a patient terminal; The expert's end is used on mannequin models, while the patient's end is used on real patients; The expert and patient terminals have the same modules, including a slide rail base module, a robotic arm module, a probe clip module, an ultrasound diagnostic instrument main unit module, and a remote system workstation.

[0043] The slide rail base module consists of a slide rail with gears and a robotic arm mounting base mounted on the slide rail. The robotic arm mounting base can move along the slide rail and integrates a motion motor and a position detection module. The motion motor drives the robotic arm mounting base to move along the slide rail, and the position detection module monitors the position of the robotic arm mounting base relative to the slide rail in real time, thereby facilitating the synchronized operation of the slide rail base module at the expert end and the patient end. The robotic arm module is specifically set on the robotic arm mounting base.

[0044] The robotic arm module uses a six-axis robotic arm, with the expert and patient robotic arm modules moving completely synchronously. Therefore, when the expert's robotic arm module is moved by the expert, it can collect motion data and upload the joint angle and position information. At the same time, the patient's robotic arm module controls the movement of the ultrasound probe to reproduce its trajectory.

[0045] The probe clamp module is used to hold and fix the ultrasonic probe. The probe clamp module is installed on the robotic arm module. The probe clamp module is specifically composed of a matrix of pins. The pins are subjected to air pressure or spring force and have an elastic tendency to extend, which can hold and fix ultrasonic probes of different shapes.

[0046] The robotic arm module can actively control the movement of the ultrasound probe, and can also passively detect the amount of movement based on the movement of the ultrasound probe, so that the robotic arm module at the expert end and the robotic arm module at the patient end can move synchronously. During remote diagnosis, the expert, positioned at the expert's end, performs ultrasound diagnosis on a mannequin. The expert moves the ultrasound probe on their end, causing a robotic arm module on the expert's end to passively detect the movement and send the data to the patient's end. The robotic arm module on the patient's end moves synchronously. When the ultrasound probe driven by the patient's robotic arm module comes into contact with the patient, the patient's robotic arm module feeds back resistance data to the expert's robotic arm module, causing the expert's robotic arm module to generate corresponding resistance. Throughout this process, the mannequin is selected to have a size that closely approximates that of a real patient. The mannequin serves as a fuzzy positioning tool, assisting the expert in roughly determining the detection position of the ultrasound probe on the patient's end. For precise positioning, the expert uses the feedback resistance generated by the robotic arm module to determine the contact between the ultrasound probe and the patient, and adjusts the probe position based on the image.

[0047] The slide rail base module enables the robotic arm module to adjust its position along the height of the mannequin or real patient, with the slide rail base modules at the expert end and the patient end moving synchronously. The control device is installed on the main unit module of the ultrasound diagnostic instrument and is used to adjust the parameters of the main unit module, such as... Figure 2 As shown, the outer frame 1 of the control device has mounting holes 109. The control device of the present invention is installed on the main module of the ultrasound diagnostic instrument through mounting holes 109 and screws, and sets and controls the ultrasound diagnostic instrument. The control device can perform pressing and rotating operations, and when the expert end control device performs pressing or rotating operations, the patient end control device can automatically synchronize the operation. The remote system workstations at the expert and patient ends are connected via network communication. The remote system workstation consists of a PC host, monitor, image acquisition card, router, etc. The routers at the expert and patient ends transmit signals through a broadband dedicated line. Through the remote system workstations, the expert and patient ends can transmit images and audio, enabling real-time interaction between the expert and the patient.

[0048] The ultrasound diagnostic instrument's main unit module, robotic arm module, and slide rail base module all achieve synchronous information transmission between the expert and patient ends through a remote system workstation.

[0049] The control device in this invention, such as Figure 5As shown, during rotation, the dual-function button 2 is rotated. The outer ring gear 7 is integrally fixed with the dual-function button 2 and rotates synchronously. The outer ring gear 7 drives the cylindrical gear 8 to rotate. The rotation angle sensor 9 monitors the rotation angle information and outputs the rotation angle information to achieve rotation adjustment control. The remote diagnostic device at the other end controls the servo motor 10 based on the rotation angle information, causing the servo motor 10 to drive the cylindrical gear 8 to rotate actively. The cylindrical gear 8 then drives the outer ring gear 7 and the dual-function button 2 to rotate in the opposite direction, achieving synchronous rotation angles at both ends.

[0050] When performing the pressing operation, the finger will press on the pre-locking pressure plate 201, such as... Figure 5 and Figure 6 As shown, since the elastic force of the preset spring piece 209 is much smaller than that of the pressing spring 601, in the initial stage when the finger contacts and presses the pre-locking pressure plate 201, the pre-locking pressure plate 201 first pushes the upper support plate 208 and the square rod 207 and other structures downward through the compression ball 205. The position height of the lifting trigger 3 remains unchanged, and the moving lock plate 210 moves down and engages in the locking groove 211. The teeth of the moving lock plate 210 and the locking groove 211 mesh, locking the dual-function button 2 and the lifting trigger 3 so that they cannot rotate relative to each other. In the above process, when the finger pressing on the pre-locking pressure plate 201 rotates at an angle, since the positioning center column 202 is in contact with the upper support plate 208 through the compression ball 205, the friction is extremely small. When the finger rotates at an angle, the pre-locking pressure plate 201 rotates relative to the dual-function button 2 first, thus avoiding the dual-function button 2 from rotating relative to the lifting trigger 3 and causing an angle change before the dual-function button 2 and the lifting trigger 3 are locked.

[0051] After the dual-function button 2 and the lifting trigger 3 are locked, as the finger continues to press, the pre-locking pressure plate 201 moves down to its position, driving the dual-function button 2 to move down. The dual-function button 2 then drives the lifting trigger 3 to move down, as shown below. Figure 9 As shown, the conductive insert 401 makes conductive contact with the contact post 402, thereby turning on the switch.

[0052] like Figure 5 and Figure 10 As shown, the U-shaped lock 302 cooperates with the self-locking groove 301, so that the lifting trigger 3 is automatically locked in the lowering position when it is pressed, and unlocked and moved upward after being pressed again. The cooperation structure of the U-shaped lock 302 and the self-locking groove 301 is a common design of self-locking switches in the prior art.

[0053] The remote diagnostic device at the other end energizes the electromagnet unit 6, causing it to generate magnetic force that attracts the electromagnet disk 5 to move downward, thereby driving the lifting trigger 3 to move downward, thus simulating a press and keeping the control devices at both ends moving synchronously.

[0054] like Figure 5 and Figure 7 As shown, when the lifting trigger 3 is in the raised state and the dual-function button 2 is simultaneously fully extended upwards, the exposed area of ​​the dual-function button 2 is relatively large, making it easy to be accidentally touched and rotated. Figure 7 As shown, the present invention, through the setting of the pushing protrusion 108, compresses the piston column 106, causing the piston column 106 to move to the right. The gas in the active column cavity 104 enters the damping pneumatic bladder 103, causing the air pressure in the damping pneumatic bladder 103 to increase. The damping pneumatic bladder 103 expands slightly and comes into frictional contact with the friction ring 102, thereby increasing the rotational damping of the cylindrical gear 8, thereby increasing the rotational resistance of the dual-function button 2 and reducing the probability of accidental rotation.

[0055] When the lifting trigger 3 is in the lowered state and the dual-function button 2 is simultaneously in the lowered and retracted state, the exposed area of ​​the dual-function button 2 is small, making it less likely to be accidentally touched, and when rotating for adjustment, the hand can only hold it slightly. Figure 7 As shown, at this time, due to the downward movement of the lifting trigger 3, the pushing protrusion 108 moves downward and is misaligned with the piston column 106. The piston column 106 moves to the left under the elastic force of the return spring 107, and the gas pressure in the damping pneumatic bladder 103 decreases, thereby reducing the rotational damping of the cylindrical gear 8, which reduces the rotational resistance of the dual-function button 2. When the hand can only hold a small amount, the reduced rotational resistance of the dual-function button 2 makes it more convenient to use. The above structure makes the control device of the present invention feel better when rotating and can adapt to different extension and retraction states.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
