Referring to fig. 3, the present invention also provides a method 200 for using a bone bed preparation apparatus for joint fusion, comprising the steps of:

s101: placing the support frame 22 to a proper horizontal position according to the bone part of the patient needing to be punched, judging whether the rotating rod 12 can be inserted into the bone part of the patient needing to be punched in the downward moving process, if not, rotating the lantern ring 21, and adjusting the position of the cylinder 10 until the bone part of the patient needing to be punched in the downward moving process of the rotating rod 12 is determined; if so, the collar 21 is kept still;

the inner surface wall of the lantern ring 21 is provided with threads, the outer surface wall of the cylinder body 10 is also provided with threads, the lantern ring 21 is sleeved on the outer surface wall of the cylinder body 10, the lantern ring 21 is in threaded connection with the cylinder body 10, the support frame 22 can support the cylinder body 10, if the rotating rod 12 moves downwards after testing, and cannot be inserted into a bone part of a patient needing to be punched, the lantern ring 21 can be rotated, and as the lantern ring 21 is in threaded connection with the cylinder body 10, the cylinder body 10 can move towards the bone part of the patient needing to be punched along with the rotation of the lantern ring 21 until the handle 17 is pressed, and the rotation of the lantern ring 21 is stopped when the rotating rod 12 moves downwards and can be inserted into the bone part of the patient needing to be punched; if the rotating rod 12 moves downwards through testing, when the bone part of the patient needing punching can be inserted, the lantern ring 21 does not need to be rotated.

S102: adjusting the position of the rotating rod 12 according to the infrared ray emitted by the infrared emitter 122 through the infrared channel 121 until the infrared round point is located at the required punching position;

the infrared ray emitted by the infrared emitter 122 can be emitted along the axis direction through the infrared channel 121, and when the infrared ray is emitted to the body of the patient, a red dot is embodied, which is the axis point of the rotating rod 12, and the medical staff can move and adjust the supporting component 20 according to the situation, so that the red dot is located at the position where the patient needs to punch.

S103: start driving piece 11 to with vertical decurrent power effect on handle 17, utilize the downstream dwang 12 punches to the position that the skeleton need punch, observes simultaneously scale marking 161 or display screen, control the degree of depth that dwang 12 punched accomplishes and punches.

Wherein, after the position of punching of dwang 12 is confirmed, can start driving piece 11, driving piece 11 drives dwang 12 rotates, through pressing handle 17, and then connecting rod 16 supports and holds baffle 15, baffle 15 supports and holds driving piece 11, the vertical downstream of driving piece 11, elastic component 14 atress compression, simultaneously the vertical downstream of dwang 12 for the pivoted the lower extreme contact patient of dwang 12 needs the skeleton position of punching, and then punches, the depth of punching is decided according to the dynamics of pressing handle 17 with the hand, and medical personnel accessible observation is not before punching the numerical value on the scale mark 161 on the connecting rod 16 that indicates arrow 101 end instruction to and observe the in-process of punching, the numerical value on the scale mark 161 on the connecting rod 16 that indicates arrow 101 end instruction, therefore, the punching depth can be accurately controlled, and meanwhile, medical staff can check the descending height of the driving piece 11 detected by the position sensor by observing the display screen, so that the punching depth can be accurately controlled.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
