Abstract
The utility model discloses a laparoscopic puncture device, which comprises a puncture needle and a puncture needle sheath. The puncture needle sheath comprises a tubular needle sheath body and a needle sheath handle arranged at the end of the needle sheath body, the outer surface of the needle sheath body is covered by an airbag, the puncture needle sheath is also provided with an air guide tube communicated with the airbag, and the air guide tube is provided with the air valve. When the laparoscopic puncture device is arranged in a preset position, the airbag is inflated via the air valve, the airbag on the two sides of the skin and subcutaneous tissues can be expanded into a dumbbell shape, the laparoscopic puncture device can be firmly fixed on the skin and subcutaneous tissues, and the problems that surgical tools cannot be opened and the pressure inside the surgical cavity leaks as a result of sliding of the puncture needle sheath and the like can be avoided. The airbag contacted with the skin and subcutaneous tissues can be tightly contacted with the skin and subcutaneous tissues under air pressure, the sealing effects can be achieved, and the leakage of pressure gas in the surgical cavity can be avoided effectively.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of chamber mirror perforator.
Background technology
The mirror technology section's every field that is out at present in chamber all has very widely and to use, and the chamber mirror just is not applied in intraperitoneal, outside the abdominal cavity, is widely used, like retroperitoneum mirror, newborn chamber mirror, thoracoscope etc. yet.
Chamber mirror technology is to utilize the perforator chamber of will performing the operation to be connected with extraneous, and the structure of perforator comprises puncture needle and the puncture sheath that is coated at puncture needle, and the sheath that punctures is provided with inlet channel.After perforator thrusts the operation chamber, it is expanded,, be convenient to the hands art to obtain spacious surgical field of view through the inflation in the operation chamber of puncture sheath; Operating theater instruments undergos surgery from puncture sheath entering operation chamber simultaneously.
Mostly its puncture sheath outer surface of present perforator is bright finish or has one section annular anti-slip tank that after perforator got into the operation chamber from skin, the outer wall skidproof effect of bright finish or annular anti-slip tank was all relatively poor; Operation tool moves around; The sheath that can cause puncturing moves around, and especially newborn chamber mirror is artificially performed the operation the chamber apart from epidermis thin (anti-slip tank is inoperative basically), and the puncture sheath moves around more easily; The sheath that causes like this puncturing is loosening easily, and puncture orifice enlarges.Can bring two kinds of unfavorable results after the loosening and puncture orifice of puncture sheath enlarges: 1, the puncture sheath is loosening, and after the puncture sheath was crossed dark entering operation chamber, causing the ultrasound knife cutter head to be stayed in the puncture sheath can't open, and has a strong impact on operation technique, influence operation precision and progress.2, puncture orifice enlarges cause performing the operation chamber and the external world and communicates, and the gas of big pressure overflows from puncture sheath external surface peripheral in the operation chamber, and the cavity pressure that causes performing the operation is not enough, and the operation chamber dwindles, and influence surgical field of view, and severe patient causes performing the operation and can't carry out.
Therefore need improve perforator of the prior art, to overcome its defective.
The utility model content
In view of this; The purpose of this utility model provides a kind of chamber mirror perforator; Its sheath outer surface that punctures is provided with anti-skid structure, and the puncture sheath is secure fixation on the wall of operation chamber, and chamber gas leakage causes the problems such as the chamber dwindles of performing the operation thereby the operation tool that elimination causes because of the slip of operation chamber can't be opened, perform the operation.
This utility model chamber mirror perforator; Comprise puncture needle and puncture stylophore, the puncture stylophore comprises tubulose needle scabbard body and the stylophore handle that is arranged at the needle scabbard body end, is coated with air bag on the outer surface of needle scabbard body; Also be provided with the airway that is communicated with air bag on the puncture stylophore, airway is provided with air valve.
Further, said air valve is fixed on the stylophore handle.
The beneficial effect of this utility model: this utility model chamber mirror perforator; Through on the puncture stylophore, air bag being set, after chamber mirror perforator is inserted the precalculated position, in air bag, inflate through air valve; The air bag that is positioned at skin and subcutaneous tissue two side portions swells; Air bag becomes dumbbell shaped, and what chamber mirror perforator can be firm is fixed on skin and the subcutaneous tissue, the operation tool that the causes problems such as cavity pressure gas leakage of can't opening and perform the operation thereby the stylophore of can avoiding puncturing slides; Closely contact with skin and subcutaneous tissue under gas pressure with the air bag of skin and subcutaneous tissue contact portion, play sealing function, pressed gas is revealed in the chamber that can effectively prevent to perform the operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further described.
Fig. 1 is the structural representation of this utility model chamber mirror perforator.
The specific embodiment
Fig. 1 is the structural representation of this utility model chamber mirror perforator.
As shown in the figure; Present embodiment chamber mirror perforator; Comprise puncture needle 1 and puncture stylophore, the puncture stylophore comprises tubulose needle scabbard body 2 and the stylophore handle 3 that is arranged at the needle scabbard body end, is coated with air bag 4 on the outer surface of needle scabbard body 2; Also be provided with the airway 5 that is communicated with air bag 4 on the puncture stylophore, airway 5 is provided with air valve 6.
After chamber mirror perforator is inserted the precalculated position; Inflate in air bag 4 through air valve 6; The air bag that is positioned at skin and subcutaneous tissue two side portions swells; Air bag becomes dumbbell shaped, and what chamber mirror perforator can be firm is fixed on skin and the subcutaneous tissue, the operation tool that the causes problems such as cavity pressure gas leakage of can't opening and perform the operation thereby the stylophore of can avoiding puncturing slides; Closely contact with skin and subcutaneous tissue under gas pressure with the air bag of skin and subcutaneous tissue contact portion, play sealing function, pressed gas is revealed in the chamber that can effectively prevent to perform the operation, and guarantees that the operation intracavity visual field is broad.
In the present embodiment, said air valve 6 is fixed on the stylophore handle 3, and compact overall structure is convenient to make; Certainly if on the needle scabbard body 2 enough spaces are arranged, air valve 6 also can be arranged on the needle scabbard body 2.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
