Abstract

The utility model relates to a double-chamber balloon prostatic fovea plug which is a surgical operation apparatus suitable for prostate excision, comprising an air sac, a rubber cover and a double-cavity rubber tube. The double-cavity rubber tube is provided with an air inlet passage which is communicated with the air sac, and a physic liquor passage whose top is provided with a physic liquor outlet. The upper part of the air sac is provided with the rubber cover. After the operation of prostate excision, the air sac is positioned in a fovea and the rubber cover is positioned below the edge of the fovea. The utility model inflates the air sac via the air inlet passage and then injects the hemostasis physic liquor into the operation fovea via the physic liquor passage and the physic liquor outlet. The utility model has the advantages that fine haemostasis effect is received by using less haemostasis physic liquor.

Description

Double-chamber balloon prostatic fovea plug

This utility model relates to a kind of surgical instrument, is particularly useful for the surgical instrument of prostatectomy.

Prostatic hyperplasia is old frequently-occurring disease, needs operative treatment more.Prostate extirpation is a hemorrhagic operation, and reducing intraoperative hemorrhage is clinical for many years important subject.In the past, in prostate extirpation, once used the gauze ball filling gland nest that dips in other hemostasis medicinal liquid such as 10% formalin diluent or thrombin, but, the opening in nest chamber is open, the blood that the springs up medicinal liquid that often will stop blooding is constantly gone out the nest chamber, make it to bring into play the local hemostasis effect effectively, make doctor art open country when the nest edge is sewed up unclear.

The purpose of this utility model is to provide a kind of double-lumen air sac prostate nest plug in order to overcome above-mentioned weak point, place double-lumen air sac prostate nest plug in the nest behind prostatectomy, cover whole nest chamber, nest chamber and bladder separate, hemostasis medicinal liquid by this utility model utensil injection nest intracavity can not be overflowed from the nest mouth, expansible air bag impels the hemostasis medicinal liquid to contact wound surface in the whole nest equably, forms the pressure coating, thereby has brought into play the local hemostasis effect of medicine effectively; Expansible air bag has reduced the actual volume in nest chamber simultaneously, has saved the hemostasis chemical liquid consumption greatly; Because hemostasis has effectively been created art open country clearly for the doctor sews up the nest edge.

Description of the present utility model is as follows: double-lumen air sac prostate nest plug is made up of air bag, rubber lid, two-chamber rubber tube etc., the two-chamber rubber tube has air inlet rubber tube passage and medicinal liquid rubber tube passage, air inlet rubber tube passage and air bag intracavity inter-connection, the medicinal liquid rubber tube passes air bag central authorities, but do not communicate, medicine liquid outlet is arranged on the top of medicinal liquid rubber tube passage with the air bag inner chamber.The rubber lid is fixed on air bag top, and as air bag being likened to one " plug ", the rubber lid just looks like a gag.Place double-lumen air sac prostate nest plug in the postoperative nest of prostate, air bag is positioned at nest, and the rubber lid is positioned at nest edge below, seals the nest mouth as lid.Earlier with injection tube by air inlet rubber tube passage to airbag aeration, the aeration quantity of air bag is decided according to nest chamber size, the injection tube that reuse is equipped with the hemostasis medicinal liquid inject medicinal liquid that stops blooding by medicinal liquid rubber tube passage in nest, the hemostasis medicinal liquid is filled in the gap between air bag and nest wall, be unlikely excessive, thereby, make the hemostasis medicinal liquid give full play to the wound surface anastalsis.

Fig. 1 is the position view of double-lumen air sac prostate nest plug of the present utility model in the human body operation on prostate.1-urethra among the figure, 2-prostate postoperative nest chamber, 3-double-lumen air sac prostate nest plug.

Fig. 2 is a double-lumen air sac prostate nest plug cutaway view of the present utility model.4-medicinal liquid rubber tube passage among the figure, 5-air inlet rubber tube passage, 6-rubber lid, 7-air bag, 8-medicine liquid outlet.

Embodiment makes like this: double-lumen air sac prostate nest plug is made up of air bag (7), rubber lid (6), air inlet rubber tube passage (5), medicinal liquid rubber tube passage (4), medicine liquid outlet (8).Air inlet rubber tube passage (5) and air bag (7) intracavity inter-connection, air inlet rubber tube channel diameter is 2 millimeters, long 40 millimeters of air bag (7) two ends, the back diameter that expands can reach the 25-40 millimeter.The medicinal liquid rubber tube passes the central part of air bag (7), and its passage does not communicate with the air bag inner chamber.The diameter of medicinal liquid rubber tube passage (4) is 4 millimeters, has medicine liquid outlet (8) in its end.Medicine liquid outlet can be one, also can be two, 3 millimeters of outlet ∮.A rubber lid (6) is installed, 50 millimeters of rubber lid ∮, thick 1.5 millimeters on air bag (7) top.In extracing prostatic operation nest, place double-lumen air sac prostate nest plug, inflate to air bag (7) by air inlet rubber tube passage (5) with syringe cylinder earlier, 15 milliliters of the normal saline that will contain 2000-4000 unit's thrombin again inject in the nest by medicinal liquid rubber tube passage (4), medicine liquid outlet (8) with syringe cylinder, and it is full of in the gap between prostate nest wall and air bag.Earlier seam is pricked prostatic artery, sews up half-turn behind the prostate nest edge again, at this moment, extracts gas in the air bag out, allows air bag is flat extracts air bag out down again, and at this moment, half-turn before the nest edge is sewed up in all satisfied hemostasis in nest edge and nest chamber again, dwindles the nest mouth, finishes operation.

Advantage of the present utility model: in extracing operation on prostate, use Double-chamber balloon prostatic fovea plug of the present utility model, can use less hemostasis soup, reach the effect of quick-acting haemostatic powder, create clearly visual area for the doctor sews up the nest edge.
