Abstract
The utility model discloses an automatic gas injection pneumoperitoneum needle for puncture, which comprises a needle tube and a needle bed, and is characterized in that the needle bed is connected with the gas outlet of a breather valve; the gas inlet of the breather valve is connected with a communication rubber tube of a carbon dioxide gas injection machine; a sliding tapered needle head is arranged at the lower end in the needle tube; a gas passage is arranged along the axle center of the sliding tapered needle head; a gas injection hole communicated with the gas passage is formed in a tapered point side wall of the sliding tapered needle head; a sealing film is arranged on a tapered point outer wall of the sliding tapered needle head; and the lower opening of the sealing film is fixed on the sliding tapered needle head through a snap ring. As the automatic gas injection pneumoperitoneum needle is provided with a device capable of injecting gas automatically after an abdominal wall is punctured, the operation is convenient, time-saving and labor-saving, the puncture reaction is sensitive, and hurt of an intestinal canal is avoided; as the needle head is pushed through gas pressure, the puncture speed is easy to be controlled uniformly; and as a circular rubber sucker is arranged at the front end of the needle tube, the needle tube is easy to be controlled stably during puncture, and the operation quality can be improved.
Description
Technical field
This utility model relates to a kind of improvement of pneumoperitoneum pin, specifically a kind ofly penetrates automatic gas injection pneumoperitoneum pin, is applicable to the abdominal cavity Minimally Invasive Surgery.
Background technology
At present, in the hospital clinical, all advocate under peritoneoscope for intestinal, stomach, gallbladder and to do Minimally Invasive Surgery, before performing an operation, need earlier between stomach wall and intestinal tube, to inject CO with the pneumoperitoneum pin stomach wall that punctures
2Gas makes intestinal tube leave stomach wall, just can under laparoscopically observation, undergo surgery.Used pneumoperitoneum pin comprises needle tubing, needle stand and switch mostly at present, and needle tubing is fixed on the lower end of needle stand, and the front end of needle tubing is the syringe needle that connects as one, and switch is fixed on the middle part of needle stand, establishes the gas injection interface in the upper end of needle stand, and is connected with syringe.During use, when adding with hands when pressing to abdomen wall puncture, if penetrate stomach wall, the water pressure in the syringe reduces suddenly, just the water in the syringe flows into intraperitoneal, expression has penetrated stomach wall, pulls up syringe immediately, again with CO
2The gas tube of gas implanter is connected on the gas injection interface, injects CO
2Gas makes intestinal tube break away from stomach wall.The deficiency of this pneumoperitoneum pin is: the one, because water filling and injection CO
2Gas is lock out operation, repeatedly plug, so inconvenient operation wastes time and energy, in the plug process, the easy shaking needle body damages stomach wall or intestinal tube, causes unnecessary misery to the patient; The 2nd, owing to confirm that through the variation in water pressure of injecting puncture puts in place, so, when puncture puts in place, just below stomach wall, injected a certain amount of water, and these water are not easy to extract out, so there is certain influence in the visual field of operation; The 3rd, because puncture is the manual pressure inserting needle, so puncture speed is difficult to even control, and also relevant with operator's experience.
Summary of the invention
The purpose of this utility model is to provide a kind of and directly confirms that through the variation of air pressure puncture puts, also injects automatically CO in place
2Gas penetrate automatic gas injection pneumoperitoneum pin.
In order to reach above purpose; The technical scheme that this utility model adopted is: this penetrates automatic gas injection pneumoperitoneum pin, comprises needle tubing and needle stand, and the upper end of needle tubing is fixedly connected with needle stand; It is characterized in that: described needle stand is connected with the gas outlet of breather valve; At the fixing upper handle of the upside of breather valve, the axis of handle and the axis of needle tubing point-blank, the air inlet of breather valve and CO
2The connection sebific duct of gas implanter connects; Lower end in the described needle tubing is provided with the slip tapered needle; Axle center along the slip tapered needle is provided with gas passage; On the awl point sidewall of slip tapered needle, be provided with the injecting hole that is connected with gas passage; On the awl point outer wall of slip tapered needle, be provided with the envelope film, the end opening of envelope film is fixed on the slip tapered needle through snap ring, and the envelope film is attached on the injecting hole on the slip tapered needle sidewall.
This utility model is also implemented through following measure: the fixing ring-shaped rubber sucker of going up in the lower end of described needle tubing.
The overall diameter of described slip tapered needle is identical with the interior diameter of needle tubing; On the sidewall of the upper end of slip tapered needle, be provided with guide runner; On the inwall of needle tubing, be provided with axial slide, the guide runner on the slip tapered needle is stuck in the axial slide on the needle interior wall.
The card of described breather valve is provided with the pressure indicating graduation, through rotating the turning knob of breather valve, adjustment puncture pressure and gas injection pressure.
The beneficial effect of this utility model is: compare with the pneumoperitoneum pin of present use; Penetrate and begin the device inflated automatically owing to be provided with stomach wall, no longer adopt the conversion of gas injection after the first water filling, so simple in structure, easy to operate, time saving and energy saving; Penetrate simultaneously and be quick on the draw, can not injure intestinal tube; Because syringe needle is to lean on air pressure propulsive, so the control of puncture speed easy and uniform; Because the front end at needle tubing is provided with the ring-shaped rubber sucker, so the stable easily control of needle tubing when puncture can improve the operation quality.
Description of drawings
Fig. 1 analyses and observe enlarged diagram for the axis of no-feathering of this utility model to office;
Fig. 2 looks up enlarged diagram for the slip tapered needle of this utility model.
Among the figure: 1, needle tubing; 2, needle stand; 3, breather valve; 4, hands handle; 5, air inlet; 6, be communicated with sebific duct; 7, guide runner; 8, slip tapered needle; 9, injecting hole; 10, gas passage; 11, envelope film; 12, snap ring; 13, ring-shaped rubber sucker; 14, axial slide.
The specific embodiment
Make this utility model with reference to Fig. 1, Fig. 2.This penetrates automatic gas injection pneumoperitoneum pin; Comprise needle tubing 1 and needle stand 2; The upper end of needle tubing 1 is fixedly connected with needle stand 2, it is characterized in that: described needle stand 2 is connected with the gas outlet of breather valve 3, at the fixing upper handle 4 of the upside of breather valve 3; The axis of the axis of handle 4 and needle tubing 1 point-blank, the air inlet 5 and the CO of breather valve 3
2The connection sebific duct 6 of gas implanter connects; Lower end in the described needle tubing 1 is provided with slip tapered needle 8; Axle center along slip tapered needle 8 is provided with gas passage 10; On the awl point sidewall of slip tapered needle 8, be provided with the injecting hole 9 that is connected with gas passage 10; On the awl point outer wall of slip tapered needle 8, be provided with envelope film 11, the end opening of envelope film 11 is fixed on the slip tapered needle 8 through snap ring 12, and envelope film 11 is attached on the injecting hole 9 on slip tapered needle 8 sidewalls.
This utility model is also implemented through following measure: the fixing ring-shaped rubber sucker 13 of going up in the lower end of described needle tubing 1, the end opening that makes needle tubing 1 through ring-shaped rubber sucker 13 is along being positioned on the stomach wall of site of puncture.
