Specific embodiment

Below in conjunction with accompanying drawing, and technical characteristic and advantage of other above-mentioned to this utility model are described in more detail.

A kind of anti-unexpected fire design of this utility model include power switch button, circuit board, battery unit, motor and Housing, the anti-unexpected fire design can be completed to fire, return and stopping action；

The power switch button, the circuit board, the battery unit, the motor are electrically connected, their quilts It is placed in the housing, the anti-unexpected fire design can prevent the device with anti-unexpected fire design from surprisingly firing, and make Operation object escapes injury；

The power switch button is used to turn on and off power supply, and during connection, the device with anti-unexpected fire design is just Often work, device during shut-off with anti-unexpected fire design does not work, and prevents unexpected percussion；

The circuit board can provide circuit, described electronic for the electric energy of the battery unit to be conveyed to by circuit Machine, realizes the anti-unexpected percussion function of device with anti-unexpected fire design；

The battery unit is used to provide electric energy for the motor, it is ensured that the motor can be transported under electrical condition Turn；

The motor is used to convert electrical energy into kinetic energy, drive the device with anti-unexpected fire design to advance or after Move back；

The housing is used for the power switch button, the circuit board, the battery unit, motor placement On the correct position of the housing.

Circuit board shown in Fig. 1 includes six switch SW1 to SW6, the switch of two electromagnetic relays K1A and K1B control, 7 resistance R1 to R7, PTC cartridge fuses, a LED1 lamp, foot 1 and foot 2 are turned on when switch SW1 to SW5 is not pressed, and are pressed When foot 1 and foot 3 turn on, switch SW6 does not have foot to turn on when not pressing, and foot 2 is turned on foot 3 when pressing, and foot 4 is turned on foot 5.

Anti- unexpected fire design fires process：

It is manually pressed by first switching SW1, touch switch SW2 also will be pressed therewith (needs several seconds clock switch SW2 quilts Press), when switching SW2 and not also being pressed, at this moment foot 1 and foot 2 are turned on switch SW2, electromagnetic relay K1A two ends and battery Unit B AT both positive and negative polarity connects, and electromagnetic relay K1A work produces electromagnetic force turns on foot 3 and foot 4, after several seconds, switchs SW2 quilts Press, then press power switch button, triggering Fig. 1 breaker in middle SW6 are pressed, after pressing switch SW4：Battery unit positive pole one Routing switch SW6, resistance R7, LED1, switch SW2, switch SW1 are connected with battery unit negative pole, and display lamp LED1 is bright, illustrates work Work starts, another routing switch SW5 (not pressing) of battery unit positive pole, motor, switch SW4, switch SW6, PTC cartridge fuse and Parallel resistance R1 to R6, switch SW2, switch SW1 are connected with battery unit negative pole, and motor is connected with battery unit both positive and negative polarity, When motor starts to start, prevent electric current excessive, cause firing action, parallel resistance and cartridge fuse are increased in circuit loop PTC, motor is rotated forward, but rotating speed is slow, and the device with the anti-unexpected fire design is advanced slowly, advance a small distance Afterwards, structure triggering SW3 is pressed, parallel resistance and cartridge fuse PTC short circuits, the dress with the anti-unexpected fire design Pace increase is put, moment fires away.

Anti- unexpected fire design Umklapp process：

If motor is stuck during the device with the anti-unexpected fire design advances, SW4 is unclamped, while touching SW5 is pressed, and at this moment display lamp is also bright, and motor reversion, the device with the anti-unexpected fire design is forced to return.

Anti- unexpected fire design stopped process：

If motor is stuck during the device with the anti-unexpected fire design advances, if always according to SW4, touching SW5 is pressed, and at this moment display lamp is bright, and motor is only connected with battery unit negative pole, and motor stops not turning.

Anti- unexpected percussion process：

When power switch button is unclamped, switch SW6 is not turned on, and presses switch SW1 to SW5, and display lamp does not work, because switch SW6 is not turned on, and motor circuit is cut off, and motor does not turn, and the device with the anti-unexpected fire design is motionless, will not fire Go out.

Opening or closing for power switch button, decides that whether the device with anti-unexpected fire design fires, on and off switch Button is the key element for preventing the device with anti-unexpected fire design from surprisingly firing.

Fig. 2 is the control unit structure chart of the anastomat with anti-unexpected fire design, the housing of anti-unexpected fire design In anastomat device body main body 354 in figure, power switch button is a circular shift knob 318, as shown in figure 3, manually Unscrew, prevent touching open, produce maloperation, with switch SW6 be connected, the on and off switch by open or close and switch SW6 synchronizations.

Anastomat fires process：

The hand-reset lid 351 in Fig. 4 is pressed, trigger switch SW1 is pressed, subsequently press the second reset switch 331, touched Send out switch SW2 to be pressed, circular shift knob 318 in manual unlocking Fig. 3, trigger switch SW6 is pressed, cocking 31, touches Send out percussion switch 315, and then trigger switch SW4 button 314, switch SW4 buttons 314 are pressed, motor via switch SW4, Switch SW6, PTC cartridge fuse and parallel resistance R1 to R6, switch SW2, switch SW1 loops, the rack of slow drive anastomat 232 travel forward, and the front groove of rack 232 promotes the arch section of contact chip 333, makes contact chip 333 connect with circuit board 317 Triggering SW3 buttons, switch SW3 is pressed, as shown in figure 5, anastomat is quickly fired away.

Anastomat stopped process：

If motor is stuck during anastomat advances, trigger 31 is unclamped, switch SW4 upsprings, presses first in Fig. 4 Reset switch 332, trigger switch SW5 button 316, switch SW5 is pressed, and motor shuts down, and anastomat is slack.

Anastomat Umklapp process：

If anastomat is stuck during advancing, motionless according to trigger 31, switch SW4 is pressed always, while pressing First reset switch 332 in Fig. 4, trigger switch SW5 button 316, as shown in fig. 6, switch SW5 is pressed, and motor reversion, kiss Clutch is forced to return.

The anti-unexpected percussion process of anastomat：

When circular shift knob 318 is turned off, even if all buttons of trigger switch SW1 to SW5, motor is slack, Anastomat cannot be fired.

Anastomat with anti-unexpected fire design can by a circular shift knob 318 control anastomat work with It is no, it is real to realize preventing unexpected percussion from occurring, make surgical object escape injury.

6. anti-unexpected fire design as claimed in claim 5, it is characterised in that the circuit board also includes that the 6th switchs, and presses Under the first switch, the second switch, it is described 3rd switch, it is described 4th switch, it is described 5th switch and the described 6th During switch, the motor does not turn；Press the first switch, the second switch, the 3rd switch, the 5th switch With the described 6th switch, when unclamping the 4th switch, the motor reversion.

7. anti-unexpected fire design as claimed in claim 6, it is characterised in that unclamp the 3rd switch, press first and open It is described electronic when at least one in pass, the second switch, the 3rd switch, the 4th switch and the 5th switch Machine does not turn, and prevents unexpected percussion from occurring.

8. anti-unexpected fire design as claimed in claim 6, it is characterised in that the anti-unexpected percussion switch is that a circle is opened Button is closed, is connected with the described 3rd switch, open or close the circular shift knob, the 3rd switch is beaten open or close therewith Close.

9. a kind of anastomat, it is characterised in that including arbitrary described anti-unexpected fire design in claim 1-8.
