The utility model discloses a sheath bottom sets up safe calibrating device puncturing for medical personnel when an outpost of the tax office is got in the use at every turn the degree of depth of screw in be constant amount, when experiencing pressure and change suddenly, can in time stop the screw in operation, prevent to poke the emergence of internal organs phenomenon in the abdominal cavity, the reliable assurance patient's safety.
Description
Technical field
The utility model relates to technical field of medical instruments, and what particularly in a kind of laparoscopic surgery, use gets an outpost of the tax office.
Background technology
Laparoscopic surgery is one of common operative Modality of clinical medicine, and the first step of laparoscopic surgery is abdomen wall puncture, and this step adopts laparoscope to get an outpost of the tax office and assisted, and is generally blind and wears, and this is also the difficult point of abdomen wall puncture. Carrying out in abdomen wall puncture process, laparoscope is got the operation of an outpost of the tax office at present, no matter new hand or experienced medical personnel all judge that according to " breakthrough is felt " whether successfully puncture, judges by the sudden change of pressure in piercing process. But, for new hand, should not experience the variation of pressure, and for experienced medical personnel, although can experience in time pressure changes, but because use is got when an outpost of the tax office enters stomach wall and need to be used larger arm strength, once wear out stomach wall, need to stop in time firmly, therefore also can exist because of puncture firmly excessive, experience and break through when sense and having little time to stop in time firmly, poke the malpractice of Intraabdominal internal organs and blood vessel and occur and cause getting an outpost of the tax office. Therefore how to improve security in abdomen wall puncture process significant.
Summary of the invention
The utility model technical issues that need to address are to provide a kind ofly can have safety protection function, can effectively prevent that laparoscope that abdomen wall puncture process Zhong Qu an outpost of the tax office occurs abdominal visceral browser and injury of blood vessel phenomenon is with getting an outpost of the tax office.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
Calibration formula laparoscope with getting an outpost of the tax office, comprises puncture sheath and is arranged on the tube core at puncture sheath center, on the outer wall of described puncture sheath bottom, is provided with external screw thread; On the puncture sheath of described tube core bottom, be provided with safe calibrating installation, safe calibrating installation is cylinder locating piece, the center of cylinder locating piece is provided with the through hole through puncture sheath, is provided with the internal thread being equipped with mutually with the sheath external screw thread that punctures on the inwall of cylinder locating piece through hole.
Above-mentioned calibration formula laparoscope, with getting an outpost of the tax office, is fitted with handheld board on the puncture sheath on described tube core top, between handheld board and tube core top, is provided with spring.
Above-mentioned calibration formula laparoscope, with getting an outpost of the tax office, is provided with the alarm module that sends alarm signal for tube core in the time wearing out skin in described handheld board; Described alarm module comprises single-chip microcomputer, circuits for triggering and is arranged on the pressure sensor of the corresponding spring in handheld board center, the output of pressure sensor connects the input of single-chip microcomputer, the output of single-chip microcomputer connects the input of circuits for triggering, and the output of circuits for triggering connects the buzzer being arranged on puncture sheath outer wall.
Owing to having adopted above technical scheme, the obtained technological progress of the utility model is as follows.
The utility model is by arranging safe calibrating installation in puncture sheath bottom, making medical personnel's each screw-in depth in the time that an outpost of the tax office is got in use is fixed amount, in the time experiencing sudden changes in pressure, can stop in time screwing in operation, effectively prevent the generation of abdomen wall puncture process Zhong Qu an outpost of the tax office to abdominal visceral browser and injury of blood vessel phenomenon, even if medical personnel's reaction has certain time delay, because the amount of travel of tube core is very little, screw in the degree of depth be also not enough to poke Intraabdominal internal organs, Reliable guarantee patient safety.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structured flowchart of alarm module described in the utility model.
Wherein: 1. puncture sheath, 2. tube core, 3. spring, 4. safe calibrating installation, 5. external screw thread, 6. buzzer, 7. handheld board.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of calibration formula laparoscope is with getting an outpost of the tax office, and its structure as shown in Figure 1, comprises puncture sheath 1, tube core 2, handheld board 7 and safe calibrating installation 4, and 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 hand-held; Safe calibrating installation 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.
In the utility model, safe calibrating installation 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.
When the utility model uses, the bottom face of cylinder locating piece is adjacent to patient skin, then takes handheld board, rotation puncture sheath, can carry 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 tube core is advanced has shortened a puncture sheath circumference, stop the time of reaction therefore to medical personnel in the moment of prick skin, effectively prevent the generation of Liao Qu an outpost of the tax office to abdominal visceral browser and injury of blood vessel phenomenon.
Experience significantly the variation of pressure when making medical personnel wear out skin in tube core bottom, in the present embodiment, between handheld board 7 and tube core top, be provided with spring 3. Carry out in piercing process medical personnel, spring is along with the continuous compression screwing, in the time of tube core prick skin, tube core enters abdominal cavity fast, 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's tube core bottom to wear out skin, the utility model is also provided with alarm module in handheld board, sends alarm signal for tube core in the time wearing out skin, in time medical personnel is reminded. In the present embodiment, the structure of alarm module as shown in Figure 2, comprises single-chip microcomputer, circuits for triggering, buzzer 6 and pressure sensor, and buzzer 6 is arranged on the outer wall of puncture sheath; Pressure sensor is arranged on handheld board center, and corresponding with the top of spring, for the variation of sensed pressure; The output of pressure sensor connects the input of single-chip microcomputer, and for the pressure information of perception is transferred to single-chip microcomputer, single-chip microcomputer is analyzed the variation of pressure signal; The output of single-chip microcomputer connects the input of circuits for triggering, in the time that single-chip microcomputer analyzes pressure and diminishes suddenly in the process progressively increasing, sends triggering and conducting signal to circuits for triggering; Circuits for triggering are connected buzzer loop, and buzzer warning, plays timely reminding effect to medical personnel.
