Detailed Description

The present invention will be described in detail with reference to fig. 1, and the exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The utility model provides an anti-leakage puncture suction sleeve, which comprises a hollow tube 2 with the front end capable of penetrating into the tumor along with a puncture suction device 1, wherein the puncture suction device is sleeved in the inner cavity of the hollow tube, and the hollow tube adopts a transparent plastic tube, thereby avoiding influencing the surgical field; the front end of the puncture needle is designed into a wedge shape, so that the puncture needle can be conveniently and better wrapped to better enter the interior of a tumor, and the risk of cyst fluid extravasation at the moment of puncture is reduced; the inner cavity of the hollow tube is slightly larger than the diameter of the puncture aspirator, so that the puncture aspirator can freely move in the inner cavity, and the interference with the hollow tube is avoided; the front end of the hollow tube is provided with a front balloon 3 and a rear balloon 4 which are inflated to clamp and seal a puncture needle 5 of the puncture aspirator to penetrate into a puncture hole of a tumor, so that a sac liquid in the tumor is prevented from permeating into an abdominal cavity from the puncture hole in the puncture process, and the chance of iatrogenic rupture is reduced.

Specifically, the rear balloon is inflated to abut against the outer surface of the tumor so as to adjust the depth of the front end of the hollow tube penetrating into the tumor, and the front balloon extends into the tumor. When the front end of the hollow tube penetrates into the tumor through the puncture, the front balloon is not inflated, so that the front end of the hollow tube can enter the tumor; the tumor capsule wall is collapsed after the capsule liquid in the tumor is sucked out by the puncture aspirator, and the inflated front balloon can expand the interior of the tumor on one hand, so that the puncture needle is very favorable for wider and more accurate operation, and the surgical field of view is excellent; on the other hand, the tight rear saccule is matched to clamp the sac wall around the puncture, so that the leakage prevention of the sac liquid is realized.

In the implementation process, the front and rear balloons are in contact slowly and are abutted tightly with each other along with continuous inflation of the front and rear balloons, and due to deformation of the two balloons, the abutting force of the two balloon walls far away from the puncture port is possibly larger, so that the abutting force of the two balloon walls near the puncture port is reduced, therefore, the scheme is designed, namely, an anti-leakage balloon 6 is arranged on the hollow tube between the front balloon and the rear balloon, and the anti-leakage balloon can block the puncture port after being inflated. When the anti-leakage air bag is not inflated, one part of the anti-leakage air bag penetrates into the tumor along with the front end of the hollow tube, and the other part of the anti-leakage air bag is remained outside the tumor, so that the anti-leakage air bag after being inflated has a good anti-leakage effect. The anti-seepage air bag is in a cone shape with small front end diameter and large rear end diameter after being inflated, so that the purpose of blocking the puncture hole is achieved, the cone-shaped anti-seepage air bag takes the hollow pipe as a rotating center, the processing is convenient, the gradually enlarged diameter of the cone-shaped anti-seepage air bag can be better adapted to the puncture hole, and a better anti-seepage effect is achieved. In practice, a portion of the front and rear balloons may be disposed on the outer wall of the anti-leakage balloon such that the front and rear balloons are in close proximity; a certain space can be reserved between the front balloon and the rear balloon, and the space is provided with an anti-leakage air bag.

The utility model discloses a hollow tube rear end is located the belly operation mouth outside and is equipped with protection air bag 7, and it can cover the belly operation mouth, prevents that the puncture aspirator from following the utility model discloses a when withdrawing from in the puncture aspiration cover, probably remaining bag liquid drips on the belly outer wall, guarantees that bag liquid can not follow belly operation mouth and flow in the abdominal cavity to further reduce the ruptured chance of iatrogenic source. The protection air bag still has the location the utility model discloses the effect of puncture suction cover guarantees that puncture suction cover fixes on abdominal operation mouth. As another mode, the rear end of the hollow tube is provided with a protective film which can cover the abdominal operation opening, and the protective film can also cover the abdominal operation opening and prevent the sac liquid from dripping on the left and right of the outer wall of the abdomen. The mode of adopting the protection film is simpler. Preferably, the anti-leakage air bag, the protective air bag, the front air bag and the rear air bag are inflated or exhausted by adopting the independent air pipes 8 arranged on the pipe wall of the hollow pipe, so that the size of the air bag is convenient to adjust, and the adaptability is stronger. In the implementation process, two adjacent annular saccules, namely a front saccule and a rear saccule, are arranged at a position about 0.5cm away from the end face of the front end of the hollow tube, and the two saccules are positioned at two sides of the puncture hole, namely, the puncture hole is clamped, so that the puncture suction sleeve can be stably positioned on a tumor on one hand, and the puncture hole is conveniently sealed on the other hand. An anti-leakage air bag is arranged between the two air bags, so that when the puncture aspirator exits from the surface of the tumor, the bag liquid in the tumor can be prevented from flowing out from the puncture opening along the front end of the hollow tube, and the operation part is prevented from being polluted.

The use method of the anti-leakage puncture suction sleeve of the utility model is described in detail as follows:

before puncture, the anti-leakage air bag, the front air bag and the rear air bag are not inflated, the puncture aspirator is sleeved into the hollow tube of the utility model, and the length of the sleeve is preferably the puncture needle only exposing the front end of the puncture aspirator; then the puncture aspirator and the puncture suction sleeve penetrate into the tumor together, the penetration depth is about 1.5cm, then the balloon is inflated backwards through the trachea, and the balloon is tightly attached to the outer surface of the tumor, so that the penetration depth of the front end of the hollow tube can be conveniently adjusted; then the front saccule is inflated, so that the puncture suction sleeve of the utility model is fixed on the tumor and the puncture hole is sealed; then the anti-leakage air bag is inflated to block the puncture hole, and the puncture hole is further sealed. In the operation process, because the front balloon and the rear balloon press the tumor capsule wall, when the puncture needle changes the direction and moves forwards and backwards for suction, the capsule liquid in the tumor is prevented from seeping out from the puncture opening. After the puncture is finished, the air in the front balloon is discharged firstly, then the air in the back balloon and the air in the anti-leakage balloon are discharged respectively, and finally the hollow tube is withdrawn from the puncture opening and the abdominal operation opening. In the implementation process, as the cyst fluid in the tumor is sucked away, the tension of the tumor is reduced, the cyst wall of the tumor collapses and is easy to deform, when the puncture suction sleeve of the utility model is withdrawn, after the front balloon and the rear balloon are exhausted, the puncture suction sleeve is not withdrawn from the tumor firstly, but the titanium clip, the forceps clip or the wire sleeve is used for clipping or tying the tumor capsule wall around the puncture hole, the collapsed capsule wall covers the front end of the hollow tube, because the titanium clip, the forceps clip or the ligation clip tightly clamps, the cyst fluid can not leak from the puncture, then the tumor and the puncture suction sleeve are moved into the abdominal puncture TROCA, then the puncture suction sleeve is rapidly withdrawn from the TROCA, and finally withdrawn from the abdominal operation port, thereby greatly reducing the cyst fluid brought into the abdominal cavity or polluting the abdominal puncture port, through the puncture suction sleeve of the utility model, the tumor-free effect of the open abdomen operation can be achieved or even exceeded.

The above embodiments are provided only for the purpose of illustration, and not for the purpose of limitation, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention.
