[0048] Example 3, please refer to the attached Fig.10 The present invention provides a technical solution: a positioning method for an orthopedic door-type nail, comprising the following steps:

[0049] Step 1: First, the patient lies flat on the bed, and the restraint belt is passed around the patient's hands and legs and plugged into the inner wall of the plug sleeve, and then the patient's hands and legs are fixed by the A adsorption block and the B adsorption block;

[0050] Step 2: Next, start the A stepper motor, which drives the A threaded rod to rotate. The A threaded rod can drive the support assembly to move while rotating. At this time, the support assembly drives the lateral adjustment assembly and the drilling assembly to move to the position where the patient needs to nail;

[0051] Step 3: Then adjust the position of the drilling assembly through the lateral adjustment assembly, adjust the drilling assembly to the top of the nailing position, and then start the A hydraulic rod and the drive motor at the same time, and drive the A gear, B gear and C gear to rotate synchronously through the drive motor. The rotation of the B gear and the C gear can also drive the drilling column to rotate. The A hydraulic rod drives the drilling column to move down to drill holes. After the drilling is completed, start the A stepper motor to reverse and drive the support assembly away from the nailing position of the patient;

[0052] Step 4: Then start the B stepper motor to drive the B threaded rod to rotate. The B threaded rod rotates and drives the door-type nail fixing structure to move to the punching position. The position of the door-type nail assembly is adjusted by starting the drive motor to place the door-type nail on the top of the placement plate.

[0053] Step 5. Finally, move the damping shaft to move the toggle plate from the horizontal angle to the vertical angle, start the B hydraulic rod to drive the positioning plate to move downward, and the B hydraulic rod moves downward to drive the positioning plate to move downward. The positioning plate can also drive the door-type nails to move downward while moving downward. Start the micro motor to drive the two-way threaded rod to rotate, and drive the placement plate to move to the opposite side. The placement plate locks the door-type nails to fix the position of the door-type nails.

[0054] In this embodiment, stepper motor A 51 and stepper motor B 52 serve as power sources for moving the positioning structure 3 and the door-type nail fixing structure 4. Reversing stepper motor A 51 and stepper motor B 52 can drive the positioning structure 3 and the door-type nail fixing structure 4 to move above the lying bed 1.

[0055] The driving structure 5 includes an A stepper motor 51 , a B stepper motor 52 , an A threaded rod 53 and a B threaded rod 54 . The output end of the A stepper motor 51 is fixedly connected to one end of the A threaded rod 53 , and the output end of the B stepper motor 52 is fixedly connected to one end of the B threaded rod 54 .

[0056] In this embodiment, the restraint structure 2 is used to fix the position of the patient. After the patient lies flat on the reclining bed 1, the restraint belt 21 is wrapped around the patient's hands and legs and then the restraint belt 21 is passed through the connector sleeve 24.

The adsorption block B 23 is installed on the top of the plug-in sleeve 24, and the adsorption block A 22 is installed on the top of the restraint belt 21.

[0058] Specifically, stepper motor A 51 and stepper motor B 52 are used as power sources for moving the positioning structure 3 and the door-type nail fixing structure 4. The forward and reverse rotation of stepper motor A 51 and stepper motor B 52 can drive threaded rod A 53 and threaded rod B 54 to rotate forward and reversely. The rotation of threaded rod A 53 and threaded rod B 54 can drive the positioning structure 3 and the door-type nail fixing structure 4 to move. When the positioning structure 3 and the door-type fixing structure move, the position can be adjusted on the top of the reclining bed 1, and the position of the X-axis and Y-axis can be adjusted subsequently in cooperation with the lateral adjustment component 32 and the relative adjustment structure 43.

[0059] Working principle:

[0060] The first step is to firstly lie flat on the reclining bed 1, and pass the restraint belt 21 around the patient's hands and legs and plug into the inner wall of the plug sleeve 24, and then fix the patient's hands and legs through the A adsorption block 22 and the B adsorption block 23. Secondly, start the A stepper motor 51, and the A stepper motor 51 drives the A threaded rod 53 to rotate. The A threaded rod 53 can drive the support assembly 31 to move while rotating. At this time, the support assembly 31 drives the lateral adjustment assembly 32 and the drilling assembly 33 to move, and move to the position where the patient needs to nail, and then adjust the position of the drilling assembly 33 through the lateral adjustment assembly 32, and adjust the drilling assembly 33 to the top of the position where nailing is required, and then start the A stepper motor 51 at the same time. The A hydraulic rod 332 and the driving motor 335 are driven, and the A gear 337, the B gear 338 and the C gear 339 are driven to rotate synchronously through the driving motor 335. The B gear 338 and the C gear 339 can drive the drilling column 336 to rotate while rotating. The A hydraulic rod 332 drives the drilling column 336 to move downward to punch holes. After the punching is completed, the A stepping motor 51 is started to reverse and drive the support assembly 31 away from the patient's nailing position. Then, the B stepping motor 52 is started to drive the B threaded rod 54 to rotate. The B threaded rod 54 can be driven to move the door-type nail fixing structure 4 to the punching position while rotating. The position of the door-type nail assembly 44 is adjusted by starting the driving motor 431, and the door-type nail is placed on the top of the placement plate 445.

[0061] The second step, finally, move the damping shaft 441 to move the moving plate 442 from the horizontal angle to the vertical angle, start the B hydraulic rod 443 to drive the positioning plate 444 to move downward, the B hydraulic rod 443 moves downward to drive the positioning plate 444 to move downward, and the positioning plate 444 can drive the door-shaped nail to move downward while moving downward, start the micro motor to drive the two-way threaded rod to rotate, and drive the placement plate 445 to move to the opposite side, and the placement plate 445 drives and locks the door-shaped nail to fix the position of the door-shaped nail. At this point, the entire work process ends.
