Abstract
The utility model provides an endoscope puncture set comprising a puncture needle and a puncture sheath. The puncture sheath comprises a tubular sheath body and a sheath handle arranged on the end portion of the tubular sheath body, two annular grooves are formed in the surface of the tubular sheath body at intervals, elastic expansion air bags are arranged in the annular grooves or an elastic expansion membrane covers openings of the annular grooves so that sealed spaces can be formed in the annular grooves, the tubular sheath body is provided with a valve, an airway tube is arranged in the wall of the tubular sheath body, and the elastic expansion air bags or the annular grooves are connected with the valve through the airway tube. When the endoscope puncture set is arranged in a preset position, air is inflated in the elastic expansion air bags or the annular grooves so that the endoscope puncture set can be fixed to human skin or subcutaneous tissue, and the puncture sheath is prevented from falling off. The endoscope puncture set solves the problem that due to sliding and falling off of the puncture sheath, an operation is interrupted and even passively opened, and meanwhile pressure gas in an operation cavity is prevented from leaking due to the fact that the elastic expansion air bags or the elastic expansion membrane is in tight contact with the skin and the subcutaneous tissue.

Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of chamber mirror perforator, and the sheath that makes to puncture is fixed on the wall of operation chamber, has avoided affecting the carrying out of operation because the puncture sheath moves around.
The utility model discloses a kind of chamber mirror perforator, comprise puncture needle and puncture sheath, the puncture sheath comprises the tubular sheath body and is arranged at the sheath handle of tubular sheath end of body, described tubular sheath surface is interval with 2 annular grooves, in described annular groove, be provided with the elastic expansion air bag, described tubular sheath body is provided with valve near sheath handle one end, is provided with airway in described tubular sheath body tube wall, and described elastic expansion air bag is connected with valve by airway.
Further, described valve quantity is 2, and with one of them elastic expansion air bag, is connected respectively.
Further, between described 2 annular grooves, spacing distance is 0.5～2cm.
Further, described annular groove cross sectional shape be in rectangle or circular arc any one.
As realizing the second technical scheme of the present utility model, a kind of chamber mirror perforator, comprise puncture needle and puncture sheath, the puncture sheath comprises the tubular sheath body and is arranged at the sheath handle of tubular sheath end of body, described tubular sheath surface is interval with 2 annular grooves, described annular groove opening is covered with elastomeric film and makes in annular groove to form confined space, described tubular sheath body is provided with valve near sheath handle one end, in described tubular sheath body tube wall, be provided with airway, described annular groove is connected with valve by airway.
Further, described valve quantity is 2, and with one of them annular groove, is connected respectively.
Further, between described 2 annular grooves, spacing distance is 0.5～2cm.
Further, described annular groove cross sectional shape be in rectangle or circular arc any one.
The beneficial effects of the utility model are: this utility model chamber mirror perforator, by the elastic expansion air bag arranged on the puncture sheath or the annular groove that is covered with elastomeric film, after chamber mirror perforator is placed into precalculated position, by valve to the elastic expansion air bag or be covered with in the annular groove of elastomeric film and inflate, the elastic expansion air bag or the elastomeric film that are positioned at skin and subcutaneous tissue two side portions swell into dumbbell shaped, chamber mirror perforator can be stable be fixed on abdominal wall, chest wall, on the skin and subcutaneous tissue of wall of urinary bladder, the operation process caused is interrupted thereby the sheath of can avoiding puncturing slides, even passive open surgery problem, with the elastic expansion air bag of skin and subcutaneous tissue contact portion or elastomeric film under gas pressure with skin and subcutaneous tissue close contact, play sealing function, in the chamber that can effectively prevent from performing the operation, pressed gas is revealed.
