DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0022] Embodiment 1:

[0023] like Figure 1-4 As shown, the utility model is an auxiliary fixation device for medical robot surgery, including a fixing plate 7, a movable block 6 is slidably connected inside the fixing plate 7, a rotating shaft 1 is rotatably connected inside the movable block 6, a limiting gear 11 and a lower fixing member 19 are respectively sleeved on the outer side of the rotating shaft 1, a mounting block 14 is fixedly installed on the front surface of the movable block 6, a manual adjustment bolt 13 is threaded inside the mounting block 14, and one end of the manual adjustment bolt 13 is rotatably connected to a clamping block 12 engaged with the limiting gear 11.

[0024] like Figure 2 As shown, a fixing block 10 is symmetrically fixedly installed on one side of the fixing plate 7 , and a fixing hole 15 is opened on the upper surface of each fixing block 10 , so as to facilitate fixing the device by means of bolts through the fixing hole 15 .

[0025] During implementation, the lower fixing member 19 and the movable block 6 are rotatably connected by a rotating shaft 1, and a limit gear 11 is installed on the outer side of the rotating shaft 1. By rotating the hand-adjusting bolt 13, the clamping block 12 rotatably connected thereto is engaged with the limit gear 11, so that the lower fixing member 19 and the upper fixing member 3 rotated at a certain angle can be fixed, thereby solving the technical problem that the auxiliary fixing components used in the auxiliary fixing device for medical robot surgery are inconvenient to adjust according to needs after installation and fixation, resulting in poor adaptability and reduced practicality.

[0026] Embodiment 2:

[0027] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: the upper surface of the lower fixing member 19 is hinged with an upper fixing member 3, and a buckle 2 is commonly provided on one side of the upper fixing member 3 and the lower fixing member 19, and arc grooves 5 are provided on the opposite surfaces of the upper fixing member 3 and the lower fixing member 19, and an airbag 4 is commonly fixedly installed on the inner sides of the two arc grooves 5, and the mounting block 14 is L-shaped. The tooth gap of the limiting gear 11 is 0.14mm, which improves the sensitivity of the engagement between the clamping block 12 and the limiting gear 11. A screw rod 17 is screwed inside the movable block 6, and one end of the screw rod 17 is rotatably connected to the fixed plate 7, and the other end of the screw rod 17 passes through the fixed plate 7 and is fixedly connected to the knob 8, and rolling grooves 9 are provided on the upper and lower surfaces of the inner cavity of the fixed plate 7, and a receiving groove 18 is provided on the upper and lower surfaces of the movable block 6, and a ball 16 rollingly connected to the rolling groove 9 is provided inside the receiving groove 18.

[0028] During implementation, by rotating the knob 8, the screw rod 17 connected to it is driven to rotate, so as to control the outer movable block 6 to drive the lower fixing part 19 to move forward and backward, which is convenient for patients of different heights. In addition, the movable block 6 and the fixed plate 7 are movably connected by the receiving groove 18, the ball 16 and the rolling groove 9, so as to avoid friction and improve the smoothness of adjustment.

[0029] When installing the technical solution, the fixing plate 7 is fixed on the operating table by bolts through the fixing holes 15, so that the device is fixed. When the front and rear positions of the upper fixing member 3 and the lower fixing member 19 need to be adjusted, the knob 8 is turned to drive the screw rod 17 connected thereto to rotate, and the outer movable block 6 drives the lower fixing member 19 to move forward and backward. At this time, the ball 16 rolls inside the rolling groove 9 to avoid friction. When in use, the patient's ankle is placed inside the upper fixing member 3 and the lower fixing member 19, and the airbag 4 is filled with a certain amount of gas to protect the ankle. When the angle of the upper fixing member 3 and the lower fixing member 19 needs to be adjusted, the hand-adjusting bolt 13 is first turned to separate the block 12 connected thereto from the limit gear 11, and then the lower fixing member 19 is rotated to a certain angle with the rotating shaft 1 as the center, and finally the hand-adjusting bolt 13 is turned again to make the block 12 connected thereto engage with the limit gear 11, so that the upper fixing member 3 and the lower fixing member 19 after the angle adjustment are fixed.
