The triode Q of level conducting or low level conducting, wherein when the triode Q be connected using high level, the first electric current is less than second
Electric current.
Specifically, the course of work and working principle of the puncture outfit circuit are as follows: infrared emission tube 1111 with reference to Fig. 4
Emit infrared signal in real time in puncture outfit puncture process, in the state that puncture outfit does not penetrate abdominal wall, infrared ray letter
It number is reflected by abdominal wall, infrared receiver tube 1112 then receives the infrared signal of stronger reflection, to generate stronger
Photoelectric current, i.e. the second electric current, divider resistance R0 then gets biggish pressure drop as a result, and D point voltage is smaller, because triode Q is high electricity
Flat turn-on transistor, D point voltage is lower than the threshold voltage of triode Q control terminal at this time, and triode Q is in an off state, by electricity
The circuit that source 14, the second protective resistance R2, prompt unit 13 and triode Q are formed is not turned on, and prompt unit 13, which is in, closes
State；After puncture outfit penetrates abdominal wall, the infrared signal that infrared emission tube 1111 emits is needed by longer-distance
The reflection of intra-abdominal organ, it is clear that the infrared signal for reflexing to infrared receiver tube 1112 is weaker, by infrared receiver tube
1112 receiving infrared-ray signals are less, and infrared receiver tube 1112 then generates weaker photoelectric current, i.e. the first electric current, divide as a result,
Piezoresistance R0 then gets lesser pressure drop, and D point voltage is larger, and be greater than triode Q control terminal threshold voltage, triode Q this
When it is in the conductive state, thus conducting by power supply 14, the second protective resistance R2, prompt unit 13 and triode Q form return
Road, prompt unit 13 are opened, and are carried out puncture outfit and are penetrated the information alert of abdominal wall state, doctor after receiving information alert,
Know that puncture outfit penetrates abdominal wall, then stop the operation puncturing to abdominal wall, thus assist doctor's judgement, stops puncturing in time,
Prevent from causing a deviation due to a lack of experience the case where leading to puncture too deep injury organ.
As shown in figure 4, indicator light can be used in prompt unit 13, doctor judges puncture outfit by the light on and off of viewing lamp
Whether abdominal wall is penetrated, such as when puncture outfit does not penetrate abdominal wall, indicator light is off-state, when puncture outfit penetrates abdominal wall
Afterwards, indicator light is lighted, to be prompted；Or using opposite prompting mode, i.e., in puncture process, indicator light is to be always on shape
State, after puncture outfit penetrates abdominal wall, indicator light extinguishes.Select andding set for indicator light can be according to actual puncture outfit structure
It is designed, such as LED light is set as the tail portion of indicator light or puncture outfit on puncture outfit, partially transparent structure can be used
It constitutes, the materials such as electroluminescent film is set in the transparent configuration, replace LED light as instruction.Optionally, prompt unit 13 is gone back
Buzzer can be increased or individually prompted using buzzer.
Fig. 5 is the cut-away section structural schematic diagram of another puncture outfit provided by the embodiment of the utility model, with reference to Fig. 5,
Puncturing state sensing unit further includes the second infrared tube 112, the extension in the sensing direction and puncturing lever of the second infrared tube 112
Direction intersection.By the way that two infrared tubes are arranged, distance sensing can be carried out to different directions, so that more efficiently sensing is worn
The puncture state for piercing device helps to improve the accuracy of puncture state judgement.
It include that puncture outfit penetrates abdominal wall state and puncture outfit and do not penetrate abdominal cavity wall-like during puncturing abdominal wall
State, puncture outfit penetrate abdominal wall state there is also crossing to penetrate abdominal wall state, and puncture outfit, which is crossed, in order to prevent penetrates abdominal wall, causes
The device that puncture outfit damages abdominal cavity is dirty, and the utility model embodiment additionally provides another working principle of the second infrared tube
And work-based logic, Fig. 6 are that the logic circuit of the first infrared tube and the second infrared tube provided by the embodiment of the utility model shows
It is intended to, is introduced below with reference to the course of work and working principle of the Fig. 5 and Fig. 6 to two infrared tubes, firstly, first is red
It is as follows to the circuit connecting mode of pipe 111 and the second infrared tube 112 outside, with reference to Fig. 6, the output end of the second infrared tube 112
The output end of the connection of NAND gate circuit input terminal, the output end of not circuit and the first infrared tube 111 is separately connected and door electricity

With reference to Fig. 7, specifically, the needle portion of puncturing lever enters abdominal cavity at this time, and first is infrared when puncture outfit just penetrates abdominal wall
Pipe is also at it is intraperitoneal, output be located at intraperitoneal electric signal, and the second infrared tube 112 because with the first infrared tube
111 have the distance of setting, and the second infrared tube 112 is still surrounded by abdominal wall at this time, and the output of the second infrared tube 112 is located at abdomen
Electric signal in cavity wall, the electric signal that corresponding each infrared tube is obtained in different conditions, can set positioned at intraperitoneal telecommunications
Number logically 1, the electric signal logically 0 in abdominal wall, at this point, the second infrared tube 112 connects not circuit,
Its signal for inputting AND gate circuit input terminal is 1, and the signal that the first infrared tube 111 inputs AND gate circuit input terminal is 1, this
When, AND gate circuit output end output 1 is prompted to control prompt unit, and doctor can stop puncture procedure according to the prompt；
When puncture outfit, which was in, penetrates state, the second infrared tube 112 and the first infrared tube 111 enter in abdominal cavity, and second is red
It is outside 1 to the signal that pipe 112 exports, after not circuit negates, the electric signal for inputting AND gate circuit is 0, electric with door at this time
Road output end then exports 0, and prompt unit does not work at this time, and doctor can be by prompt unit by opening to the state closed, judgement
Puncture outfit had been in the state of penetrating, and should stop puncturing in time, or puncture outfit of pulling back, and avoided puncture outfit injured patient's device dirty.
Puncture outfit still carries out the sensing of puncture state in unused state in order to prevent, and still carries out puncture shape
Construction of switch can be arranged in puncturing its circuit, for closing the power supply of power supply in state prompt.Unlike switch unit,
