Abstract
The utility model discloses a kind of abdominal cavity pipet pipe arrangement preventing from damaging omentum majus, described pipe arrangement is placed on the outside of abdominal cavity pipet, and pipe arrangement comprises pipe arrangement body, and whole pipe arrangement body is distributed with hole.The abdominal cavity pipet pipe arrangement preventing damage omentum majus provided by the utility model, be placed on the outside of suction catheter, whole pipe arrangement body is distributed with hole, guarantee when pipe arrangement far-end immerses Intraabdominal liquid, pipe arrangement near-end still has hole to be positioned on liquid level, air can be entered, the suction hole negative pressure suction force of pipe arrangement is reduced, even if there is omentum majus to press close to pipe arrangement hole, also can not be drawn onto in pipe arrangement because pressure is little, even if or be inhaled into, increase because vicious cycle can not occur negative pressure suction force, can not make omentum majus that comparatively major injury occurs.
Description
Technical field
This utility model relates to medical instruments field, particularly a kind of abdominal cavity pipet pipe arrangement preventing damage omentum majus.
Background technology
Existing abdominal cavity pipet has straight tube and bend pipe two kinds, and no matter any, its basic structure is all made up of interior pipe, outer tube, nut and joint.Interior pipe far-end only has a suction hole, and distal outer tube is provided with multiple suction hole, and near-end atresia, outer tube is socket-connected by nut and interior pipe.When using abdominal cavity pipet attraction abdominal cavity liquid, if all suction holes of outer tube are all immersed in below liquid level, when one of them or several cavity are close to omentum majus, because omentum majus is organized very soft, omentum majus can be caused to be adsorbed, fit in the suction hole of outer tube, now, owing to blocking one or several hole of outer tube when omentum majus, can because the minimizing of liquid hole can be attracted, the negative pressure suction force in remaining hole is increased, result makes omentum majus be inhaled into further, causes damage, even hemorrhage.If processed not in time, there will be vicious cycle, negative pressure suction force is larger, is easilier sucked by omentum majus, and hole more of omentum majus blocking, negative pressure suction force is larger, and result is easy to the damage causing omentum majus.Clinically, surgeon's solution to this problem is separated by inner and outer pipes, two handss hold outer tube and interior pipe respectively, distal outer tube is immersed in abdominal cavity liquid, immerse in outer lumen by the hole of distal outer tube, in outer tube, attract liquid with interior pipe simultaneously, once there is omentum majus to be inhaled into phenomenon, pipe in improving immediately, make to occur space between inner and outer pipes, air is entered, the negative pressure suction force of outer tube hole is reduced, make by the omentum majus that adsorbs unlikely be inhaled into more, by reducing the negative pressure suction force of outer tube hole, and timely mobile outer tube position, omentum majus is separated with outer tube, avoid further Greater Omentum Injury occurring, but this action need experience, bad control.
Utility model content
For overcoming the shortcomings and deficiencies of above-mentioned prior art, this utility model provides a kind of abdominal cavity pipet pipe arrangement preventing from damaging omentum majus.
The technical solution of the utility model is:
Prevent the abdominal cavity pipet pipe arrangement damaging omentum majus, described pipe arrangement is placed on the outside of abdominal cavity pipet, and pipe arrangement comprises pipe arrangement body, and whole pipe arrangement body is distributed with hole.
Preferably, described pipe arrangement inboard wall of tube body is provided with the projection that three proximally extend to far-end.
Preferably, the internal diameter of described pipe arrangement body 3.5-4.5mm larger than suction catheter external diameter.
Preferably, described three projections are 120 degree of distributions each other on pipe arrangement inboard wall of tube body.
Preferred further, the distal tip of described pipe arrangement body is circular arc.
The utility model has the advantages that: the abdominal cavity pipet pipe arrangement preventing from damaging omentum majus provided by the utility model, be placed on the outside of abdominal cavity pipet, whole pipe arrangement body is distributed with hole, guarantee when pipe arrangement far-end immerses Intraabdominal liquid, pipe arrangement near-end still has hole to be positioned on liquid level, air can be entered, the suction hole negative pressure suction force of pipe arrangement is reduced, even if there is omentum majus to press close to pipe arrangement hole, also can not be drawn onto in pipe arrangement because pressure is little, even if or be inhaled into, vicious cycle increases owing to can not occur negative pressure suction force, can not make omentum majus that comparatively major injury occurs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is the structural representation preventing the abdominal cavity pipet pipe arrangement damaging omentum majus described in the utility model.
Detailed description of the invention
On the basis of existing commercially available abdominal cavity pipet, this utility model designs a kind of abdominal cavity pipet pipe arrangement.As shown in Figure 1, what this utility model disclosed prevents the abdominal cavity pipet pipe arrangement damaging omentum majus, for being enclosed within the outside of abdominal cavity pipet, described pipe arrangement comprises pipe arrangement body 1, whole pipe arrangement body is distributed with hole 2, internal diameter 4 mms larger than abdominal cavity pipet external diameter of pipe arrangement body 1, the distal tip of described pipe arrangement body is circular arc, conveniently inserts abdominal cavity.The quantity of the hole 2 on pipe arrangement body is more, density is comparatively large, guarantees that, when pipe arrangement far-end immerses Intraabdominal liquid, pipe arrangement near-end still has hole to be positioned on liquid level, can enter air.Described pipe arrangement body 1 inwall is provided with the projection 3 that three proximally extend to far-end, guarantees that the inwall of pipe arrangement and the outer surface of abdominal cavity pipet keep uniform distance.Article three, projection 3 is 120 degree of distributions each other on pipe arrangement inboard wall of tube body.
When carrying out the attraction of intraperitoneal liquid, this utility model pipe arrangement is enclosed within abdominal cavity pipet, when this utility model far-end gos deep into intraperitoneal liquid, owing to also there being a lot of pipe arrangement hole on liquid level, air can enter, the suction hole negative pressure suction force of pipe arrangement is reduced, even if there is omentum majus to press close to outer tube hole, also can not be drawn onto in pipe arrangement because pressure is little, even if or be inhaled into, increase because vicious cycle can not occur negative pressure suction force, also can not make omentum majus that comparatively major injury occurs.This utility model pipe arrangement serves the effect of similar bamboo strainer, and by intra-abdominal organ, comprise omentum majus and be isolated in outside suction catheter, abdominal cavity liquid then can freely enter in pipe arrangement, is siphoned away by the vacuum suction hole of abdominal cavity pipet by far-end.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications done according to the spirit of this utility model main technical schemes, all should be encompassed within protection domain of the present utility model.
