Abstract
The utility model relates to a medical surgical instrument, more specifically to a puncturing surgical instrument. A gap blocking device for puncture cannulas is composed of an air bag and an aerating valve, wherein the aerating valve (3) is communicated with an air cavity (7) of the air bag. The utility model is characterized in that the air bag is in the shape of a hollow cylinder, the diameter of a hollow cavity (6) in the air bag is corresponding to the diameter of the puncture cannulas, and the air cavity (7) is arranged between the outer wall (2) of the air bag, and the inner wall (8) of the air bag. An annular side skirt (4) and nipples (5) are arranged on the outer wall (8) of the air bag, and the nipples (5) are hemispherical solid projections and are irregularly arranged. The utility model has the characteristics of simple structure and convenient use, and effectively seals gaps on the periphery of the puncture cannulas, so that injected CO2 can be prevented from escaping, and the gas injecting quantity or operation sutures does not need to be increased.
Description
Technical field
This utility model relates to a kind of medical surgical instrument, relates to a kind of puncture operating theater instruments specifically.
Background technology
Minimally invasive surgery has become the development main flow of surgery in recent years, and little otch, low-wound are the common targets of pursuing of surgeon and patient.According to the physical optics image-forming principle, certain distance (focal length) must be arranged between eyepiece and the object, it also is like this performing an operation with the lacuna mirror.But organize gappedly for making, just must artificially use CO
2Gas fills up a lacuna, the not tight phenomenon of puncture casing periphery seal often occurs in surgical operation, CO
2Gas is easily overflowed from puncture casing gap location on every side, like this CO
2Gas has reduced, and the interstice that is directed at operative site reduces, and the influence operation is normally carried out.At present, clinical two kinds of methods of general employing that address this problem:, reach requirements of operation, the gas (CO that misses like this by improving per minute gas injection rate (L) 1, by quick insufflation
2) can be replenished very soon, but this is a kind of waste after all.2, close puncture casing peripheral clearance by the operation stitching method, but waste time and energy, and bad sealing.
Summary of the invention
At above-mentioned deficiency, this utility model purpose is to provide a kind of puncture casing gap stopper simple in structure, easy to use, and it seals close puncture casing peripheral clearance effectively, prevents the CO that injects
2Gas evolution need not to improve gas injection rate or operation stitching.
To achieve these goals, the technical solution of the utility model is: puncture casing gap stopper, it is made up of air bag, charging valve, charging valve 3 communicates with the air chamber 7 of air bag, it is characterized in that air bag is a hollow cylinder, the diameter of air bag internal cavity 6 is corresponding with the puncture casing diameter, is air chamber 7 between gasbag ektexine 2 and the air bag inwall 8.
Described gasbag ektexine 8 is provided with side skirt 4, is annular.
Described side skirt 4 is 2.
Described gasbag ektexine 8 is provided with nipple 5, for the solid projection of hemispherical, becomes irregular layout.
Described nipple 5 is 12.
Described air bag, internal diameter are 10mm, and external diameter is 15mm, and side skirt 4 diameters are 17mm, and nipple 5 diameters are 2mm, and nipple 5 projecting heights are 1mm.
Described air bag, internal diameter are 12mm, and external diameter is 18mm, and side skirt 4 diameters are 20mm, and nipple 5 diameters are 2mm, and nipple 5 projecting heights are 1mm.
Described bag material is silica gel or PVC material.
This utility model is owing to adopt said structure, and charging valve 3 is given air chamber 7 inflations of air bag, makes its outside expansion, eliminates the gap of puncture casing periphery, thereby has prevented CO
2Gas evolution can carry out operation smoothly; Side skirt 4 is set, so that become feeler to be deep in the gap of organizing muscle; The solid projection nipple 5 of 12 hemisphericals of irregular distribution with to organizing sidewall to play the side direction pressurization, plays fixation.The utlity model has characteristics simple in structure, easy to use.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, puncture casing gap stopper, it is made up of air bag, charging valve, charging valve 3 communicates with the air chamber 7 of air bag, air bag is a hollow cylinder, and the diameter of air bag internal cavity 6 is corresponding with the puncture casing diameter, is air chamber 7 between gasbag ektexine 2 and the air bag inwall 8.Described gasbag ektexine 8 is provided with side skirt 4, is annular, and side skirt 4 is for being 2, between the two side skirts 4 at a distance of 2cm.Described gasbag ektexine 8 is provided with nipple 5, is the solid projection of hemispherical, and nipple 5 is 12, becomes irregular layout.
Described air bag, internal diameter are 10mm, and external diameter is 15mm, and side skirt 4 diameters are 17mm, and nipple 5 diameters are 2mm, and nipple 5 projecting heights are 1mm.
Described air bag, internal diameter are 12mm, and external diameter is 18mm, and side skirt 4 diameters are 20mm, and nipple 5 diameters are 2mm, and nipple 5 projecting heights are 1mm.
Described bag material is silica gel or PVC material.Points for attention:
1, material: can select the material of harmless, anti-certain pressures (8bti) such as silica gel, PVC for use, and require transparent, high temperature resistant.
2, profile: interior diameter is that 10mm or two kinds of specifications of 12mm are to satisfy the needs of different Trocar.Wherein the sealing part at two ends can narrow slightly 1mm with sealing inner face gap (flexible slightly getting final product).
External diameter is corresponding 15mm or 18mm, and external diameter is actual to be the diameter of air bag.Its length is only short than puncture casing, is 6cm.About general inflation 15ml.
3, fixing: in the operative process, the apparatus of mirror need pass in and out repeatedly, requires firm being fixed in the interstice of this apparatus energy, and two annular side skirts, 4 diameters are 17mm or 20mm.
