Abstract
The invention discloses a laparoscope approach taking clamp provided with a skin lifting mechanism. The laparoscope approach taking clamp comprises a puncture sheath and a tube core arranged at the center of the puncture sheath. The puncture sheath at the bottom end of the tube core is provided with a safety calibration mechanism assembled with the puncture sheath in a threaded mode. The skin lifting mechanism for upwards pulling the skin around the puncture sheath is arranged on the safety calibration mechanism. The safety calibration mechanism is arranged at the bottom end of the puncture sheath, so that the screwing-in depth is fixed each time when a medical worker uses the approach taking clamp, and the medical worker timely stops screwing-in operation to prevent the phenomenon of abdominal organ puncture when feeling abrupt pressure change. In addition, the skin around the puncture sheath can be reliably sucked up to facilitate the operation performed by the medical worker and reduce the operating difficulty before puncture operation is performed.
Description
Technical field
The present invention relates to technical field of medical instruments, what particularly use in a kind of laparoscopic surgery gets an outpost of the tax office.
Background technology
Laparoscopic surgery be clinical medicine common one of surgically, the first step of laparoscopic surgery is abdomen wall puncture, and this step adopts peritoneoscope to get an outpost of the tax office and assisted, and be generally blind and wear, this is also the difficult point of abdomen wall puncture.Carrying out in abdomen wall puncture process at present, the operation of an outpost of the tax office got by peritoneoscope, regardless of new hand or experienced medical personnel, all judges that whether puncture is successful according to " breaking through sense ", namely judged by the sudden change of pressure in piercing process.But, the change of pressure should not be experienced for new hand, and for experienced medical personnel, although pressure change can be experienced in time, but need to use larger arm strength owing to using to get when an outpost of the tax office enters stomach wall, once wear out stomach wall, need to stop firmly in time, therefore also can exist because puncture is firmly excessive, have little time when experiencing breakthrough sense to stop firmly in time, and cause getting the malpractice generation that Intraabdominal internal organs and blood vessel are poked by an outpost of the tax office.In addition, before puncture procedure carries out, medical personnel need with two towel forceps gripping point of puncture both sides skins, in skin gripping process, at least need two medical personnel's compounding practices, a people carries skin, and another people carries opposite side skin, make great strength will get an outpost of the tax office with hands again and protrude into skin, operated by two people is wasted time and energy, and not easily holds dynamics and feel, and may occur towel forceps avulsion, cause larger cut and damage on skin, bring misery to patient.Therefore the safety how improved in abdomen wall puncture process is significant.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind ofly can have safety protection function, can lift the skin near point of puncture on puncture procedure forward direction and prevent the peritoneoscope of skin injury with getting an outpost of the tax office.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
A kind of peritoneoscope with skin extraction mechanism is with getting an outpost of the tax office, its structure as shown in Figure 1, comprise puncture sheath 1, tube core 2, handheld board 7, safe correcting mechanism 4 and skin extraction mechanism 8, tube core 2 is arranged on puncture sheath 1 center, can puncture to skin under external force; Handheld board 7 is fitted in the top of puncture sheath 1, facilitates medical personnel's hands to hold; Safe correcting mechanism 4 is arranged on the puncture sheath of tube core bottom, for controlling the amount of travel of medical personnel's puncture, plays calibration function; Skin extraction organization establishes on safe correcting mechanism, for upwards stretch puncture sheath around skin.
In the present invention, safe correcting mechanism is cylinder locating piece, the center of cylinder locating piece is provided through the through hole of puncture sheath, and the inwall of cylinder locating piece through hole is provided with female thread, and the outer wall of puncture sheath 1 bottom is provided with the external screw thread 5 be equipped with mutually with the through hole of cylinder locating piece.
Skin extraction mechanism 8 comprises flat cross bar 81, slide block 82, connecting rod 83 and some suckers 84.Flat cross bar 81 is horizontally disposed with on the locating piece of safe correcting mechanism, and the both ends of flat cross bar 81 are respectively by montant 811 connection sliding block 82 be fixedly connected with, and connecting rod 83 is fixedly connected on slide block 82 bottom, and connecting rod 83 connects a sucker 84 respectively by multiple branch again.The bottom of montant 811 is slidably arranged in slide block 82, and the side of slide block is provided with through hole, and on montant, the position of corresponding through hole arranges some pin-and-holes from top to bottom, between montant and slide block by through through hole and the alignment pin 85 inserting pin-and-hole locate, as shown in Figure 2.Certainly, in actual application, the two above skin extraction mechanisms of cover can also be symmetrical arranged.
When the present invention uses, the bottom face of cylinder locating piece is adjacent to patient skin, then by the skin of each sucker suction near point of puncture, then upwards lifts slide block, after skin tensioning, located by alignment pin, just can carry out abdomen wall puncture operation.In operating process, the vertical dynamics directly applied on skin can be converted to the revolving force in rotary course, the step pitch of being advanced by tube core shortens a puncture sheath circumference, stop the time of reaction in the moment of prick skin therefore to medical personnel, effectively prevent and get the generation of an outpost of the tax office to abdominal visceral browser and blood vessel injury phenomenon.
Experiencing the change of pressure when to wear out skin in tube core bottom for making medical personnel significantly, in the present embodiment, between handheld board 7 and tube core top, being provided with spring 3.Carry out in piercing process medical personnel, spring along with the continuous compression screwed, when tube core prick skin, tube core enters abdominal cavity fast, spring loses the resistance of skin and abrupt release, makes medical personnel obviously can experience the change of pressure, and stops puncture procedure.
For further intuitively reminding medical personnel's tube core bottom to wear out skin, the present invention is also provided with alarm module in handheld board, sends alarm signal for tube core when wearing out skin, reminds in time to medical personnel.In the present embodiment, the structure of alarm module as shown in Figure 3, comprises single-chip microcomputer, circuits for triggering, buzzer 6 and pressure transducer, and buzzer 6 is arranged on the outer wall of puncture sheath; Pressure transducer is arranged on handheld board center, and corresponding with the top of spring, for the change of sensed pressure; The outfan of pressure transducer connects the input of single-chip microcomputer, and for the pressure information of perception is transferred to single-chip microcomputer, the change of single-chip microcomputer to pressure signal is analyzed; The outfan of single-chip microcomputer connects the input of circuits for triggering, when single-chip microcomputer analyze pressure diminish suddenly in the process progressively increased time, send triggering and conducting signal to circuits for triggering; Circuits for triggering connect buzzer loop, and buzzer warning, plays timely reminding effect to medical personnel.
