[0019] A headrest frame is connected to the side wall of the central frame.

[0020] A method for using an ultrasonic medical assisted simulation detection device comprises the following steps:

[0021] S1. The patient lies on the bed with his head placed on the headrest. Due to the change in the gravity of the head, the headrest moves downward to drive the center frame to move downward synchronously, and the center frame drives the hinged plates on both sides to rotate inward relative to each other. Since the clamping plates are provided with inclined grooves, the hinged plates slide in the inclined grooves through the guide blocks when rotating, so that the two clamping plates are pressed inward and contact the patient's head.

[0022] S2, then the rubber plate on the side wall of the clamping plate contacts the patient's head, the rubber plate moves backward under the force, the end of the rubber plate squeezes the inclined plate, the inclined surface of the inclined plate is set outward, so that the inclined plate moves backward under the pressure, driving the push rod to move forward, and the telescopic lever on the push rod starts to move forward. Since the connection between the telescopic lever and the push rod is telescopic, and the other end of the telescopic lever is not telescopic, the rotation of the telescopic lever can push the friction block out of the sliding groove, and the friction block fits tightly with the inclined groove, so that the guide block cannot move. At this time, the two clamping plates cannot move, so that the clamping plates are locked to the patient's head;

[0023] S3, then, the staff starts the servo motor, and the servo motor drives the outer sleeve rod to rotate. Due to the threaded matching arrangement between the outer sleeve rod and the external threaded rod, the rotation of the outer sleeve rod pushes the external threaded rod forward, and the external threaded rod drives the detection head forward through the connecting frame. At this time, the connecting frame will synchronously push the sliding bin forward, and the spring telescopic rod in the inner wall of the sliding bin slides in the first guide groove;

[0024] When the spring telescopic rod passes the half distance of the first guide groove, the spring telescopic rod pushes the transmission rod to rotate, and the transmission rod synchronously drives the push rod to rotate, and the push rod then drives the toggle rod of the I-shaped structure to rotate, and the front end of the toggle rod is connected with the wedge block in the slot on the outer wall of the toggle plate, and the wedge block is pushed out of the toggle plate, and the toggle plate loses the restriction, and when the toggle rod rotates, the tension spring can be pulled apart, so that when the toggle plate contacts the restriction, the toggle plate is reset by the tension spring and rotates in the same direction, and at this time, the toggle plate drives the transmission plate to rotate through the metal plate;

[0025] S4. With the rotation of the transmission disk, the liquid storage bin at the left end of the transmission disk rotates clockwise along the transmission disk, so that the liquid storage bin gradually moves to a position flush with the detection head. At this time, the nozzle in the liquid storage bin contacts the block, and the nozzle moves backward as a whole. At this time, since the liquid cavity is full of liquid and a sealing block is inserted in the liquid inlet, the liquid inlet is not connected to the liquid storage bin. When the nozzle moves backward, the connecting column in the nozzle is squeezed forward by the liquid, and the connecting column is connected to the liquid outlet groove, so that the liquid is squeezed out through the nozzle and ejected onto the detection head;

[0026] Then the sliding bin continues to move forward, and when it passes the remaining half of the first guide groove, the V-shaped structure is adopted, so that the transmission rod can be pushed to rotate in the opposite direction, so that the liquid storage bin can be driven to reverse again, so that the liquid storage bin is reset, and then the sliding bin enters the extension groove from the first guide groove, so that the detection head at this time protrudes out of the detection box and contacts the patient's head skin for detection;

[0027] S5. Finally, when the detection is completed, the outer sleeve rod is driven in the reverse direction by the servo motor. The outer sleeve rod rotates in the reverse direction and drives the detection head to be retracted inward through the external threaded rod. At this time, along with the retraction of the detection head, the sliding bin enters the second guide groove from the extension groove. The second guide groove is arranged opposite to the first guide groove, so that the transmission rod rotates in the reverse direction and the cleaning barrel is rotated to the lowest end. The plug-in block on the side wall of the cleaning barrel is inserted into the connecting frame, so that the connecting frame can drive the cleaning barrel to move backward when the detection head is reset backward;

[0028] Following the movement of the cleaning cylinder, the moving block in the cleaning cylinder is pressed against the limiting block, so that the moving block is forced to slide backward on the power rod. Since the moving block and the power rod are connected by a threaded structure, the backward movement of the moving block can push the power rod to rotate, and the power rod drives the cleaning plate to wipe and clean the detection head until the sliding bin is completely moved out of the second guide groove, and the cleaning cylinder is reset by following the rotation of the transmission disk again.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the present invention, by providing the first guide groove and the second guide groove, the control member can be continuously pushed to rotate back and forth, so that the detection head contacts the nozzle and the cleaning plate respectively, and the coupling agent is sprayed and cleaned, which is convenient for automatic operation.

[0031] In the present invention, by setting the control part, the liquid storage bin and the cleaning cylinder can be stably rotated back and forth by 90 degrees to cooperate with the detection head for use.

[0032] In the present invention, by setting the headrest frame, when the patient lies on the hospital bed, the head is pressed down, and the clamping plates on both sides can be controlled to position the patient's head, thereby avoiding affecting the detection accuracy.

[0067] A headrest frame 413 is connected to the side wall of the center frame 42. Through the force applied to the headrest frame 413, the two clamping plates 49 are controlled to clamp the patient's head and adapt to the heads of different patients. The fixed-point locking is convenient for locking the patient's head.

[0068] In this embodiment, Figures 1 to 16 As shown, a method for using an ultrasonic medical assisted simulation detection device comprises the following steps:

[0069] S1. The patient lies on the bed 1 with his head placed on the headrest frame 413. Due to the change in the gravity of the head, the headrest frame 413 moves downward to drive the center frame 42 to move downward synchronously. The center frame 42 drives the hinge plates 43 on both sides to rotate inwards relative to each other. Since the clamping plate 49 is provided with an inclined groove 410, the hinge plate 43 slides in the inclined groove 410 through the guide block 44 when rotating, so that the two clamping plates 49 are pressed inwards to contact with the patient's head.

[0070] S2, then the rubber plate 412 on the side wall of the clamping plate 49 contacts the patient's head, and the rubber plate 412 is forced to move backward, and the end of the rubber plate 412 squeezes the inclined plate 411, and the inclined surface of the inclined plate 411 is set outward, so that the inclined plate 411 is pressed to move backward, driving the push rod 47 to move forward, and the telescopic lever on the push rod 47 starts to move forward. Since the connection between the telescopic lever 48 and the push rod 47 is telescopic, and the other end of the telescopic lever 48 is not telescopic, the rotation of the telescopic lever can push the friction block 46 to move out of the sliding groove 45, and the friction block 46 is tightly fitted with the inclined groove 410, so that the guide block 44 cannot move. At this time, the two clamping plates 49 cannot move, so that the clamping plates 49 are locked to the patient's head;

[0071] S3, then, the staff starts the servo motor, and the servo motor drives the outer rod 32 to rotate. Due to the threaded matching arrangement between the outer rod 32 and the externally threaded rod 33, the rotation of the outer rod 32 pushes the externally threaded rod 33 to move forward, and the externally threaded rod 33 drives the detection head 35 to move forward through the connecting frame 34. At this time, the connecting frame 34 will synchronously push the sliding bin 310 to move forward, and the spring telescopic rod 311 in the inner wall of the sliding bin 310 slides in the first guide groove 37;

[0072] When the spring telescopic rod 311 passes through the half distance of the first guide groove 37, the spring telescopic rod 311 pushes the transmission rod 36 to rotate, and the transmission rod 36 synchronously drives the push rod 312 to rotate, and the push rod 312 drives the toggle rod 3143 of the I-shaped structure to rotate, and the front end of the toggle rod 3143 is connected with the wedge block 3146 in the slot on the outer wall of the toggle plate 3142, and the wedge block 3146 is pushed out of the toggle plate 3142, and the toggle plate 3142 loses its restriction. When the toggle rod 3143 rotates, the tension spring 3145 can be pulled apart, so that when the toggle plate 3142 contacts the restriction, the toggle plate 3142 is reset by the tension spring 3145 to rotate in the same direction, and at this time, the toggle plate 3142 drives the transmission plate 3147 to rotate through the metal plate;

[0073] S4. With the rotation of the transmission disk 3147, the liquid storage bin 3149 at the left end of the transmission disk 3147 rotates clockwise along the transmission disk 3147, so that the liquid storage bin 3149 gradually moves to a position flush with the detection head 35. At this time, the nozzle 31413 in the liquid storage bin 3149 contacts the block, and the nozzle 31413 moves backward as a whole. At this time, since the liquid cavity 31410 is full of liquid and the sealing block 31411 is inserted in the liquid inlet, the liquid inlet is not connected with the liquid storage bin 3149. When the nozzle 31413 moves backward, the connecting column 31415 in the nozzle 31413 is squeezed forward by the liquid, and the connecting column 31415 is connected with the liquid outlet groove, so that the liquid is squeezed out through the nozzle 31413 and ejected onto the detection head 35;

[0074] Then the sliding chamber 310 continues to move forward, and when it passes the remaining half of the first guide groove 37, the V-shaped structure is adopted, so that the transmission rod 36 can be pushed to rotate in the opposite direction, so that the liquid storage chamber 3149 can be driven to reverse again, so that the liquid storage chamber 3149 is reset, and then the sliding chamber 310 enters the extension groove 38 from the first guide groove 37, so that the detection head 35 at this time protrudes out of the detection box 31 and contacts the patient's head skin for detection;

[0075] S5. Finally, when the detection is completed, the outer sleeve rod 32 is driven in the reverse direction by the servo motor. The outer sleeve rod 32 rotates in the reverse direction and drives the detection head 35 to be retracted inward through the external threaded rod 33. At this time, along with the retraction of the detection head 35, the sliding bin 310 enters the second guide groove 39 from the extension groove 38. The second guide groove 39 is arranged opposite to the first guide groove 37, so that the transmission rod 36 rotates in the reverse direction, and the cleaning cylinder 31416 is rotated to the lowest end. The plug-in block on the side wall of the cleaning cylinder 31416 is inserted into the connecting frame 34, so that the connecting frame 34 can drive the cleaning cylinder 31416 to move backward when the detection head 35 is reset backward;

[0076] Following the movement of the cleaning cylinder 31416, the moving block 31418 in the cleaning cylinder 31416 is pressed against the limiting block 31421, so that the moving block 31418 is forced to slide backward on the power rod 31417. Since the moving block 31418 and the power rod 31417 are connected by a threaded structure, the backward movement of the moving block 31418 can push the power rod 31417 to rotate, and the power rod 31417 drives the cleaning plate 31419 to wipe and clean the detection head 35 until the sliding bin 310 is completely moved out of the second guide groove 39, and the cleaning cylinder 31416 again follows the transmission disk 3147 to rotate and reset.

8. A method for using an ultrasonic medical assisted simulation detection device, using the ultrasonic medical assisted simulation detection device as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1. The patient lies on the hospital bed (1) with his head placed on the headrest frame (413). Due to the change in the gravity of the head, the headrest frame (413) moves downward, driving the center frame (42) to move downward synchronously. The center frame (42) drives the hinged plates (43) on both sides to rotate inward relative to each other. Since the clamping plate (49) is provided with an inclined groove (410), the hinged plate (43) slides in the inclined groove (410) through the guide block (44) when rotating, so that the two clamping plates (49) are pressed inward and contact with the patient's head. S2, then the rubber plate (412) on the side wall of the clamping plate (49) contacts the patient's head, the rubber plate (412) is forced to move backward, the end of the rubber plate (412) squeezes the inclined plate (411), and the inclined surface of the inclined plate (411) is set outward, so that the inclined plate (411) is pressed to move backward, driving the push rod (47) to move forward, and the telescopic lever on the push rod (47) starts to move forward. Since the connection between the telescopic lever (48) and the push rod (47) is telescopic, and the other end of the telescopic lever (48) is not telescopic, the rotation of the telescopic lever can push the friction block (46) out of the sliding groove (45), and the friction block (46) is tightly fitted with the inclined groove (410), so that the guide block (44) cannot move. At this time, the two clamping plates (49) cannot move, so that the clamping plates (49) are locked to the patient's head; S3, then, the staff starts the servo motor, and the servo motor drives the outer rod (32) to rotate. Due to the threaded matching arrangement between the outer rod (32) and the externally threaded rod (33), the rotation of the outer rod (32) pushes the externally threaded rod (33) to move forward, and the externally threaded rod (33) drives the detection head (35) to move forward through the connecting frame (34). At this time, the connecting frame (34) will synchronously push the sliding bin (310) to move forward, and the spring telescopic rod (311) in the inner wall of the sliding bin (310) slides in the first guide groove (37); When the spring telescopic rod (311) passes through the half distance of the first guide groove (37), the spring telescopic rod (311) pushes the transmission rod (36) to rotate, and the transmission rod (36) synchronously drives the push rod (312) to rotate, and the push rod (312) drives the toggle rod (3143) of the I-shaped structure to rotate, and the front end of the toggle rod (3143) is connected with the wedge block (3146) in the slot on the outer wall of the toggle plate (3142), and the wedge block (3146) is pushed out of the toggle plate (3142), and the toggle plate (3142) loses its restriction. When the toggle rod (3143) rotates, the tension spring (3145) can be pulled apart, so that when the toggle plate (3142) contacts the restriction, the toggle plate (3142) is reset by the tension spring (3145) and rotates in the same direction. At this time, the toggle plate (3142) drives the transmission plate (3147) to rotate through the metal plate; S4. With the rotation of the transmission disk (3147), the liquid storage bin (3149) at the left end of the transmission disk (3147) rotates clockwise along the transmission disk (3147), so that the liquid storage bin (3149) gradually moves to a position flush with the detection head (35). At this time, the nozzle (31413) in the liquid storage bin (3149) contacts the block, and the nozzle (31413) moves backward as a whole. At this time, since the liquid chamber (31410) is full of liquid and a sealing block (31411) is inserted into the liquid inlet, the liquid inlet and the liquid storage bin (3149) are not connected. When the nozzle (31413) moves backward, the connecting column (31415) in the nozzle (31413) is squeezed forward by the liquid, and the connecting column (31415) is connected to the liquid outlet groove, so that the liquid is squeezed out through the nozzle (31413) and ejected onto the detection head (35); Then, the sliding chamber (310) continues to move forward, and when it passes the remaining half of the first guide groove (37), due to the V-shaped structure, it can push the transmission rod (36) to rotate in the opposite direction, so that it can drive the liquid storage chamber (3149) to reverse again, so that the liquid storage chamber (3149) is reset, and then the sliding chamber (310) enters the extension groove (38) from the first guide groove (37), so that the detection head (35) at this time protrudes out of the detection box (31) and contacts the patient's head skin for detection; S5. Finally, when the detection is completed, the outer sleeve rod (32) is driven in the reverse direction by the servo motor. The outer sleeve rod (32) rotates in the reverse direction and drives the detection head (35) to be retracted inward through the external threaded rod (33). At this time, along with the retraction of the detection head (35), the sliding bin (310) enters the second guide groove (39) from the extension groove (38). The second guide groove (39) is arranged opposite to the first guide groove (37), so that the transmission rod (36) rotates in the reverse direction and rotates the cleaning cylinder (31416) to the lowest end. The plug-in block on the side wall of the cleaning cylinder (31416) is inserted into the connecting frame (34) so ​​that the connecting frame (34) can drive the cleaning cylinder (31416) to move backward when the detection head (35) is reset backward. Following the movement of the cleaning cylinder (31416), the moving block (31418) in the cleaning cylinder (31416) is pressed against the limiting block (31421), so that the moving block (31418) is forced to slide backward on the power rod (31417). Since the moving block (31418) and the power rod (31417) are connected by a threaded structure, the backward movement of the moving block (31418) can push the power rod (31417) to rotate, and the power rod (31417) drives the cleaning plate (31419) to wipe and clean the detection head (35) until the sliding bin (310) is completely moved out of the second guide groove (39), and the cleaning cylinder (31416) rotates again following the transmission disk (3147) to reset.
