Taking out the laparoscope: checking whether internal hemorrhage and organ injury are absent, taking out the imaging device, removing the cannula 11 after discharging gas in abdominal cavity, suturing the abdominal incision, covering with sterile gauze, and fixing with adhesive tape.
As shown in fig. 1 to 6, the present invention provides a laparoscope system comprising an imaging device 2 and a puncturing device 1; the puncture device 1 comprises a cannula 11 and a fixing device 12 arranged at one end of the cannula 11; the imaging device 2 comprises an insertion tube 21 and a holding device 22 arranged at one end of the insertion tube 21; further comprising:
the illumination device 3 comprises a first switch device 31, a second switch device 32 and a lamp 33, wherein the first switch device 31 and the second switch device 32 are both arranged on the fixing device 12, and the lamp 33 is embedded in one end, far away from the fixing device 12, of the sleeve 11;
a mirror holding device 4, wherein the mirror holding device 4 comprises a clamping device 44, and the mirror holding device 4 clamps the fixing device 12 through the clamping device 44 to conduct the first switch device 31;
the connecting device 5 is arranged on the holding device 22; the connecting device 5 is in contact with the second switching device 32 to make the second switching device 32 conductive;

With the laparoscope system of the present embodiment, after the laparoscope system is erected, the holding device 4 holds the fixing device 12 by the holding device 44 and makes the first switch device 31 conduct; the connection means 5 cause the second switching means 32 to conduct; when the control device 6 detects that the first switch device 31 and the second switch device 32 are turned on, it controls the lamp 33 to illuminate, so as to provide auxiliary illumination. Meanwhile, under the action of the mirror holding device 4, not only are both hands liberated, but also the mirror is not held manually, so that the stability is better, and the first switch device 31 can be enabled to be switched on conveniently and quickly.
In this embodiment, the first switching device 31 is turned on: the first switching means 31 form a path through which current can pass; similarly, the second switch device 32 is turned on: the second switching device 32 forms a path through which current can flow.

When only the second switch device 32 is detected to be conducted, if the control device 6 controls the lamp 33 to be turned on, it is not possible to ensure whether the holding device 44 is in place, and if the puncture device 1 shakes, the incision is damaged. Thus, the provision of the first and second switching devices 31 and 32 also serves to detect whether the image forming apparatus 2 is mounted in place and whether the holding device 44 is held in place.

When the moving member 313 is pressed by the clamping device 44, it gradually enters the accommodating groove structure 221 until the first electrode sheet 311 and the second electrode sheet 312 contact, and the circuit is conducted; at this time, the elastic limiting member 314 is in an elastic deformation state. When the clamping device 44 is separated from the fixing device 12, the restriction on the moving member 313 is released, and the elastic limiting member 314 restores the elastic deformation to drive the moving member 313 to reset.
