Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Can automatically stop the laparoscope that is selected into operation with getting an an outpost of the tax office, comprise puncture sheath 1 and puncture core 2, puncture core 2 is arranged on puncture sheath 1 center, can puncture to skin under external force. Puncture is provided with automatic prevention mechanism on sheath 1, enters behind abdominal cavity when the head end of puncture sheath 1 punctures stomach wall, automatically stops mechanism to be excited to stop puncture sheath 1 and the core 2 that punctures to continue to enter abdominal cavity.
The structure of the present embodiment as shown in Figure 1, stops mechanism to comprise safe correcting mechanism 4 and detent mechanism 8 automatically, and the top of puncture sheath 1 is provided with handheld board 7, facilitates medical personnel hand-held; Safe correcting mechanism 4 is arranged on the puncture sheath of puncture core bottom, for controlling the amount of travel of medical personnel's puncture, plays calibration function; Detent mechanism is arranged on safe correcting mechanism, for clamping puncture sheath in the time puncturing core prick skin, prevents from continuing the Intraabdominal internal organs of penetration damage.
In the utility model, safe correcting mechanism is cylinder locating piece, the center of cylinder locating piece is provided with the through hole through puncture sheath, on the inwall of cylinder locating piece through hole, is provided with internal thread, on the outer wall of puncture sheath 1 bottom, is provided with the external screw thread 5 being equipped with mutually with the through hole of cylinder locating piece.
The structure of detent mechanism 8 as shown in Figure 2, comprises pressure sensor, single-chip microcomputer, circuits for triggering, electromagnet 83 and magnetic fixture block 81, between magnet 83 and magnetic fixture block 81, connects by back-moving spring 82. The inwall of cylinder locating piece offers the groove of radial symmetric, and magnet 83, back-moving spring 82 and magnetic fixture block 81 are arranged in the groove of cylinder locating piece, and wherein electromagnet is inlaid on the inner sidewall of cylinder locating piece groove, and magnetic fixture block is positioned at groove outer end. In the present embodiment, for ensureing that magnetic fixture block firmly locks puncture sheath, the end face that magnetic fixture block contact with puncture sheath is set to the puncture arcuate structure of sheath outer wall of coupling, as shown in Figures 2 and 3.
Pressure sensor, single-chip microcomputer and circuits for triggering are connected successively, form control circuit, and electromagnet is connected in circuits for triggering; Control circuit be used for controlling electromagnet whether electric generation magnetic attraction. When in the process of normal screw-in, the charged generation magnetic force of electromagnet is adsorbed on magnetic fixture block in groove, and compression reseting spring; In the time of puncture core prick skin, pressure jump, Single-chip Controlling circuits for triggering disconnect the circuit of electromagnet, electromagnet dead electricity loses magnetism, and magnetic fixture block ejects to puncture sheath under the effect of back-moving spring, and two magnetic fixture blocks are held puncture sheath tightly, as shown in Figure 3, the sheath that makes to puncture cannot screw in operation, thereby has effectively stoped the continuation of puncture procedure, prevents the generation of Liao Qu an outpost of the tax office to abdominal visceral browser and injury of blood vessel phenomenon.
When the utility model uses, the bottom face of cylinder locating piece is adjacent to patient skin, just can carries out abdomen wall puncture operation. In operating process, the vertical dynamics directly applying on skin can be converted to the revolving force in rotary course, the step pitch that puncture core is advanced has shortened a puncture sheath circumference, has shortened travel distance; Add detent mechanism and eject locking puncture sheath in the moment of prick skin, can effectively prevent from getting the generation of an outpost of the tax office to abdominal visceral browser and injury of blood vessel phenomenon.
For making medical personnel experience significantly the variation of pressure while wearing out skin in puncture core bottom, in the present embodiment, between core top, be provided with compression spring 3 in handheld board 7 with puncturing. Carry out in piercing process medical personnel, compression spring is along with the continuous compression screwing, in the time of puncture core prick skin, puncture core enters abdominal cavity fast, compression spring loses the resistance of skin and abrupt release makes medical personnel can obviously experience the variation of pressure, and stops puncture procedure.
For further intuitively reminding medical personnel that skin is worn out in the core bottom of puncturing, the utility model is also provided with buzzer 6 on puncture sheath outer wall, the core that is used for puncturing sends alarm signal by circuits for triggering control buzzer in the time wearing out skin, in time medical personnel is reminded.
