The multifunction surgical engine that provides by this utility model is in carrying out craniocerebral operations, and the flexible axle mode is holed, can be provided powerful motivation during milling the cranium brain, and high stably rotating speed can be provided when the micro machine mode is carried out rasion.Can be used as the operation power set of department of cerebral surgery, neurosurgery and orthopaedics.

This utility model has following accompanying drawing:

Fig. 1 is a schematic block circuit diagram of the present utility model;

Fig. 2 is the electrical schematic diagram of mill control circuit of the present utility model.

Among the figure: 1-on and off switch 2-single chip machine controlling circuit 3-three-phase alternating-current motor 4-foot switch seat 5-bores and mills control circuit 6-conversion control circuit 7-mill control circuit

With reference to the accompanying drawings embodiment of the present utility model is further described.Multi-functional as shown in Figure 1 craniocerebral operations engine, have on and off switch 1, mains transformer T1, single chip machine controlling circuit 2, three-phase alternating-current motor 3 (M1), in have foot switch SB1 and Lian Lian linear sliding potentiometer W1 foot switch seat 4, bore and mill control circuit 5, conversion control circuit 6 and mill control circuit 7.Also be provided with the straight position of foot switch SB2 and duplex potentiometer W2 in the foot switch seat 4, mains transformer T1 also is provided with second subprime winding T1-2.

Conversion control circuit is by the foot switch SB2 and the relay K 3 that are located in the foot switch seat, K4, K5, diode VD10 forms, the end of foot switch SB2 is connected with the rectifier power source output plus terminal that brill mills in the control circuit, the other end and relay K 3, K4, the power input of K5 parallel connection connects, the Chang Kaiduan of the normal switching contact K3-1 of relay K 3 and normal-closed end are serially connected with respectively and bore the light emitting diode HL3 mill in the control circuit and the end of HL1, the normally closed contact K4-1 of relay K 4 is connected in series with the end that brill mills the buzzing sheet HA in the control circuit, the end of potentiometer W1 in normally closed contact K4-2 and the foot switch seat be connected in series, and the normal opened contact K5-2 of relay K 5 is serially connected with between the outfan and resistance R 20 that grinds the three terminal regulator N1 in the control circuit.

The mill control circuit is by rectifier bridge QL, three terminal regulator N1, resistance R 20, R21, R25, capacitor C 19-C22, choke coil L, duplex linear sliding potentiometer W2 in diode VD6, VD7, VD9, the foot switch seat and dc micro-motor M2 form, the input of rectifier bridge QL is connected with the two ends of the second subprime winding T1-2 of mains transformer T1, the normal opened contact K5-2 of relay K 5 is serially connected with between the outfan and resistance R 20 of three terminal regulator N1, as shown in Figure 2.
