[0008] A mainframe is arranged above the support seat, and the mainframe is electrically connected to the ultrasonic probe and the display. Four of the fixed column, movable column, universal wheel, threaded rod and turbine are arranged, and are divided into a group of two. Two of the turbines mesh with the same worm. A fixing mechanism is arranged above the support seat, and the fixing mechanism is used to fix the mainframe. The transmission mechanism includes a gear arranged on the worm, and the worm is rotatably mounted on the fixed column, and the gear is fixedly mounted on the worm. Two gears are arranged, and the two gears are connected through gear belt transmission, and one of the gears is fixedly mounted with a rotating handle.

[0036] By driving the transmission mechanism, the two worms 7 rotate and drive the turbine 6 and the threaded rod 5 to rotate, so that the movable column 3 and the universal wheel 4 move into the fixed column 2, and the fixed column 2 contacts the ground for support;

[0037] A main unit 8 is arranged above the support seat 1, and the main unit 8 is electrically connected to the ultrasonic probe 9 and the display 10. Four fixed columns 2, movable columns 3, universal wheels 4, threaded rods 5, and turbines 6 are each arranged, and two are divided into a group, and two turbines 6 mesh with the same worm 7. A fixing mechanism is arranged above the support seat 1, and the fixing mechanism is used to fix the main unit 8. The transmission mechanism includes a gear 11 arranged on the worm 7, and the worm 7 is rotatably mounted on the fixed column 2. The gear 11 is fixedly mounted on the worm 7. Two gears 11 are arranged, and the two gears 11 are connected through a gear belt 12 for transmission, and one of the gears 11 is fixedly mounted with a rotating handle 13.

[0038] In one embodiment, for the above-mentioned fixing mechanism, the fixing mechanism is provided with four groups, two of which are grouped together, and the parts and installation methods are the same, two racks 17 mesh with the first gear 19, the first gear 19 is rotatably installed inside the fixing base 14, two first gears 19 are provided, and the two first gears 19 are fixedly installed.

[0039] In one embodiment, for the host 8 , the host 8 is disposed above the fixing seat 14 , one end of the data cable 20 is fixedly mounted on the host 8 , and the other end of the data cable 20 is fixedly mounted with the ultrasonic probe 9 .

[0040] In one embodiment, for the above-mentioned display 10 , the display 10 is rotated on the host 8 .

[0041] The working principle of an elastic ultrasonic imaging image processing device proposed in the present invention is that when using the present invention, the device is first moved to a suitable position by means of a universal wheel 4, and then the two worm gears 7 are driven to rotate by a transmission mechanism, thereby driving the turbine 6 to rotate, and then driving the threaded rod 5 to rotate, thereby driving the movable column 3 to rise or fall along the inside of the fixed column 2, thereby facilitating the adjustment of the fixing mechanism, the main unit 8, the ultrasonic probe 9 and the display 10 to a suitable height, making it convenient for medical staff to operate and more convenient to use.

[0042] It is worth noting that after the use of the device, it is moved to the designated position, and then the two worm gears 7 are driven to rotate through the transmission mechanism, thereby driving the turbine 6 to rotate, and then driving the threaded rod 5 to rotate, thereby driving the movable column 3 and the universal wheel 4 to move toward the inside of the fixed column 2, and then the universal wheel 4 can be put into the inside of the fixed column 2. At this time, the fixed column 2 is in contact with the ground, thereby forming a supporting effect, preventing the device from moving when not in use due to the universal wheel 4 not being locked, thereby causing damage to the device.

[0043] Finally, the medical staff converts the received sound wave signal into an electrical signal through the ultrasound probe 9 and transmits it to the host 8 for processing, and then converts it into image data and presents it as an elastic ultrasound image on the display 10.

[0044] The working principle of the elastic ultrasonic imaging image processing device proposed by the present invention is that the host 8 can be quickly disassembled and installed through the fixing mechanism, so that the host 8 can be easily repaired and replaced.

[0045] The working principle of an elastic ultrasonic imaging image processing device proposed in the present invention is to rotate the handle 13 to drive the gear 11 to rotate, and then drive another gear 11 to rotate through the gear belt 12, thereby driving the two worm gears 7 to rotate at the same time, thereby adjusting the fixing mechanism, the main unit 8, the ultrasonic probe 9 and the display 10 to a suitable height, which is convenient for medical staff to operate and more convenient to use.

[0046] The working principle of an elastic ultrasonic imaging image processing device proposed in the present invention is that the operator moves the clamping plate 16 toward the edge of the fixed seat 14, and the compression spring 15 undergoes elastic deformation and maintains a certain tension, thereby driving the rack 17 to move along the inside of the connecting piece 18, and then driving the first gear 19 to rotate, so that the two first gears 19 rotate at the same time, and then the four clamping plates 16 move toward the edge of the fixed seat 14 at the same time, so as to facilitate the removal of the main unit 8 for replacement or maintenance.

[0047] It is worth noting that when installing the host 8, the above operation is repeated first, and then the host 8 is placed above the fixing seat 14, and then the clamping plate 16 is loosened, and the reaction force of the compression spring 15 is used to drive the four clamping plates 16 to move toward the center of the fixing seat 14 at the same time, so that the host 8 can be fixed.

[0048] The working principle of the elastic ultrasound imaging image processing device proposed by the present invention is that medical staff converts the received sound wave signal into an electrical signal through the ultrasound probe 9, transmits it to the host 8 for processing, and then converts it into image data and presents it as an elastic ultrasound image on the display 10.
