As an embodiment of the present invention, referring to fig. 1-6, the pressed rotating mechanism includes a bearing 19 fixedly installed on the drill 4, two connecting plates 20 are symmetrically installed on an outer circumferential wall of the bearing 19, ends of the two connecting plates 20 away from each other are both slidably penetrated through an inner wall of the case 1, first contact electrodes 22 are installed on upper outer walls of the two connecting plates 20, two fixing plates 21 are symmetrically installed on outer walls of two sides of the case 1, second contact electrodes 23 are installed on lower outer walls of the two fixing plates 21, a slot 15 is formed at an upper end of the drill 4, two sliders 17 are symmetrically installed on an outer wall of the output shaft 3, two sliding slots 18 are symmetrically formed on an inner wall of the slot 15, the sliders 17 are slidably installed with the sliding slots 18, and a return spring 16 is connected between a bottom wall of the output shaft 3 and an inner bottom wall of the slot 15.

The drill 4 will be under the pressure of the skull when drilling the skull, the pressure makes the drill 4 slide upwards, thereby driving the bearing 19 to move upwards, the bearing 19 drives the two connecting plates 20 to move upwards, thereby making the two first contact electrodes 22 contact with the second contact electrodes 23 on the two fixing plates 21, forming a closed circuit, at this time, the push rod motor 45 and the step motor 2 start, when drilling is completed, the drill 4 loses the pressure function instantly, the drill 4 falls a short distance under the elastic force of the reset spring 16 and the gravity of the drill 4, so that the first contact electrode 22 and the second contact electrode 23 are separated, thereby breaking the circuit, the step motor 2 and the push rod motor 45 stop simultaneously, it is worth noting that the distance between the human brain and the skull is more than or equal to 0.5cm, it is necessary to control the elastic deformation of the reset spring 16 and the distance between the first contact electrode 22 and the second contact electrode 23 within the range of less than or equal to 0.5cm Therefore, the safety during drilling is improved, the quality of drilling is improved, the medical cost is reduced, the first contact electrode 22 is not movable, only the second contact electrode 23 can move, when the push rod motor 45 drives the lower part to descend, the first contact electrode 22 and the second contact electrode 23 always move together, the second contact electrode 23 is driven only when the drill bit 4 is pressed, and only the condition can trigger the switch.

As an embodiment of the invention, referring to fig. 2 and 7, two insertion rods 41 are symmetrically installed on the outer wall of the upper end of the sleeve 26, two mounting plates 40 are symmetrically installed on the outer walls of two sides of the box body 1, two mounting plates 40 are both provided with insertion holes matched with the insertion rods 41, the outer wall of the insertion rod 41 is provided with a limiting hole 42, two ends of the limiting hole 42 are both movably inserted with limiting blocks 43, and a limiting spring 44 is connected between the outer walls of two limiting blocks 43 close to one side.

Insert on the inserted bar 41 and establish the jack, during spacing 43 was advanced by the outer wall of mounting panel 40 and is pressed spacing hole 42, after the jack was all passed to spacing 43, spacing 43 popped out spacing hole 42 under spacing spring 44's elasticity effect, sleeve pipe 26 was installed and is finished this moment, when dismantling, in pressing spacing hole 42 with two spacing 43, pull-down sleeve pipe 26 for the inserted bar 41 with the jack separation can, made things convenient for the change to parts such as sleeve pipe 26, reduced medical cost.

The working principle is as follows: utilize push rod motor 45 to install on skull positioner, can carry out position control, it is worth noting that skull positioner is prior art, and push rod motor 45 is used for promoting step motor 2 and box 1 and removes, and step motor 2 is used for driving drill bit 4 and rotates.

Drill bit 4 can receive the pressure effect of skull when driling the skull, pressure effect makes drill bit 4 up slide, thereby drive bearing 19 and move up, bearing 19 drives two connecting plates 20 and shifts up, thereby make two first contact electrode 22 and two second contact electrode 23 on the fixed plate 21 contact, form closed circuit, push rod motor 45 and step motor 2 start this moment, when accomplishing the drilling, drill bit 4 loses pressure effect in the twinkling of an eye, drill bit 4 whereabouts a short segment distance under reset spring 16's elasticity and drill bit 4 self action of gravity, make first contact electrode 22 and second contact electrode 23 separate from each other, thereby make the circuit disconnection, step motor 2 and push rod motor 45 stop simultaneously, thereby the security when having improved drilling, thereby improve the quality of drilling, medical cost has also been reduced.

The output shaft 3 drives the first gear 9 to rotate when rotating, the first gear 9 drives the two second gears 10 to rotate, the two second gears 10 drive the two rotating rods 8 to rotate, the two rotating rods 8 respectively drive the two reciprocating lead screws 14 to rotate, the reciprocating lead screws 14 respectively generate thread transmission with the two threaded pipes 13 when rotating, the two threaded pipes 13 are driven to reciprocate through the thread transmission effect, so that the two linkage plates 12 and the piston rod 11 reciprocate once, when the piston rod 11 moves upwards, the air pressure in the piston cylinder 6 is reduced, physiological saline in the two water tanks 5 can enter the piston cylinder 6 through the water inlet pipe 24, and when the piston rod 11 moves downwards, the physiological saline in the piston cylinder 6 is pressed out from the water spray pipe 7, so that the purposes of flushing and cooling are realized, the intermittent flushing and cooling purposes are achieved, and the efficiency of flushing and cooling is improved, further improving the quality and efficiency of the operation, and being worth noting that the water inlet pipe 24 and the water spraying pipe 7 are both provided with one-way valves, so as to realize one-way water inlet and outlet.

The output shaft 3 drives the reciprocating push plate 29 to rotate, the reciprocating push plate 29 continuously pushes the two movable plates 31 when rotating, the movable plates 31 can drive the pressing plate 34 to move towards the inside of the installation box 28 when being pushed, the internal air bag 32 is compressed leisurely, the movable plates 31 help the reciprocating push plate 29 to reset when being separated from the movable plates 31 under the action of the elastic force of the spring rods 30, and therefore the purpose of reciprocating pushing is achieved, and further the air bag 32 is continuously compressed.

The gasbag 32 is when being compressed, inside air is discharged by air outlet nozzle 35, treat that the gasbag 32 loses the pressure recovery shape, air in the negative pressure groove 39 passes through intake pipe 36 and enters into the gasbag 32, atmospheric pressure in the negative pressure groove 39 reduces, can see through sponge 27 and draw the air from the external world, thereby reach the purpose in blood and the bone foam is inhaled into sponge 27 around, the blood can be deposited in collector tube 38, it is worth noting, all be equipped with the check valve on air outlet nozzle 35 and the intake pipe 36, thereby realize the one-way purpose of giving vent to anger of air outlet nozzle 35 and the one-way air inlet of intake pipe 36, thereby the efficiency of retrieving blood bone foam has been improved, the cleanliness factor around the drilling has been improved, thereby the quality and the efficiency of drilling have been improved.

Insert on the inserted bar 41 and establish the jack, during spacing 43 was advanced by the outer wall of mounting panel 40 and is pressed spacing hole 42, after the jack was all passed to spacing 43, spacing 43 popped out spacing hole 42 under spacing spring 44's elasticity effect, sleeve pipe 26 was installed and is finished this moment, when dismantling, in pressing spacing hole 42 with two spacing 43, pull-down sleeve pipe 26 for the inserted bar 41 with the jack separation can, made things convenient for the change to parts such as sleeve pipe 26, reduced medical cost.
