The control system 1-1 selects one point of the medical plate 1 as an original point of a plane coordinate system, establishes the plane coordinate system according to the positions of the groups of piezoelectric bodies 2-11, and gives the groups of piezoelectric bodies 2-11 plane coordinates;
when a patient lies on the medical plate 1, the patient with different body types generates downward pressure on the piezoelectric bodies 2-11 in different positions, the piezoelectric bodies 2-11 generate current, the control system 1-1 draws the body type outline of the patient according to the coordinate position of the piezoelectric bodies 2-11 transmitting the current, the generated body type outline is marked in a plane coordinate system, the control system 1-1 controls the jacking machine 2-15 which is not subjected to pressure and is arranged on the first layer outside the body type outline according to body type outline data, and the control system 2-11 enables the clamping rails 2-12 in the plurality of groups to form a limiting ring outside the patient under the lifting of the jacking machine 2-15.
The working principle of the invention is as follows:
under the condition that does not use this local anesthesia device, card rail subassembly 2 and guide assembly 3 all are located U type mounting groove, and when using, the up end that medical board 1 was stretched out to card rail subassembly 2's partial structure, and simultaneously, card rail subassembly 2 also takes out guide assembly 3 from U type mounting groove.
When a patient lies on the medical treatment plate 1, the patient generates pressure on the piezoelectric bodies 2-11, so that the piezoelectric bodies 2-11 are deformed, thereby causing the piezo-electric body 2-11 to generate an electric current, so that the control system 1-1 in the medical board 1 can position the piezo-electric body 2-11 generating the electric current, so that the control system 1-1 traces the body contour data of the patient according to the coordinates of the piezoelectric bodies 2-11 generating the current, meanwhile, the control system 1-1 controls the camera to collect images, the control system 1-1 processes the images transmitted by the camera, analyzing the body contour of the patient in the image, superposing the body contour analyzed by the image and the body contour formed by the piezoelectric bodies 2-11, and carrying out error processing on the superposed body contour so as to calculate the correct body contour of the patient.
The control system 1-1 controls the non-pressure jacking machine 2-15 on the first layer outside the body contour according to the body contour data, so that the jacking machine 2-15 pushes the clamping rails 2-12 out of the medical plate 1 through the steering box 2-14 and the base 2-13.
The control system 1-1 controls the lifters 2-37 to push the push plates 2-31 and the bearing plates 2-21 out of the medical plate 1 according to the rising height of the clamping rails 1-1, so that the upper end faces of the push plates 2-31 are horizontal to the upper end faces of the bases 2-13, the control system 1-1 controls the distance adjusting motors 2-35 to work according to the positions of the raised clamping rails 2-12 (the clamping rails 2-12 closest to the push plates 2-31), the distance adjusting motors 2-35 adjust the distance between the two groups of bearing plates 2-21 through the screw rods 2-36 and the guide rails 2-32, and the positions of the bearing plates 2-21 correspond to the positions of the clamping rails 2-12.
After the carrying plate 2-21 is in place, the control system 1-1 controls the propulsion motor 2-34, so that the carrying plate 2-21 moves to the clamping rail 2-12 under the action of the propulsion motor 2-34 and the propulsion gear 2-33.
When the bearing plate 2-21 moves towards the clamping rail 2-12, the connecting plate 2-26 on the bearing plate 2-21 is firstly inserted into the J-shaped end of the clamping rail 2-12, after the bearing plate 2-21 moves to the clamping rail 2-12, the bearing motor 2-23 starts to work, the moving gear 2-24 is meshed with the gear rack on the clamping rail 2-12, the bearing plate 2-21 moves on the clamping rail 2-12, the camera continuously collects images of things in the front direction in the moving process of the bearing plate 2-21, and the image content is transmitted to a control system 1-1, and the control system 1-1 adjusts the direction of the clamping rail 2-12 in the advancing direction of the bearing plate 2-21 according to the image content, so that the bearing plate 2-21 can smoothly move to the next clamping rail 2-12.
After the bearing plate 2-21 moves to the position of the patient for the operation, the control system 1-1 enables the bearing motor 2-23 to stop working, so that the bearing motor 2-23 locks the position of the bearing plate 2-21, and the bearing plate 2-21 is prevented from driving the positioning plate 3-1 to shake.
After the positioning plate 3-1 moves in place, the medical staff draws out a plurality of groups of clamping rails 2-12 which do not influence the movement of the bearing plate 2-21 and carries out clamping connection, so that the clamping rails 2-12 and the bandage fix the patient.
The control system 1-1 controls the guide motor according to the position to be anesthetized, the guide motor adjusts the orientation of the guide ring 3-12, the orientation of the guide ring 3-12 corresponds to the position to be anesthetized, a medical worker pulls the top plate 3-3 on the positioning plate 3-1 open to expose the guide ring 3-12 in the visual field of the medical worker, the medical worker installs the injector on the guide ring 3-12, after the installation, the control system 1-1 controls the lifting height of the jacking machine 2-15 to continuously lower the height of the injector, and after the injector reaches the height capable of injecting (after the injection height is acquired by a camera, the control system 1-1 calculates and the medical worker operates), the jacking machine 2-15 stops working under the control of the control system 1-1, therefore, medical staff can inject anesthetic, the control system 1-1 controls the guide motor to adjust the guide ring 3-12 for multiple times according to injection times and angles required, the jacking machine 2-15 rises to a certain height after injection is completed, then the medical staff can fold the top plate 3-3 without drawing out the injector, the top plate 3-3 forms a desktop for placing medical articles, after the top plate 3-3 is folded, the positioning plate 3-1 moves to a proper position under the driving of the bearing plate 2-21, and after surgery is completed, all parts are reset under the control of the control system 1-1.
