Detailed Description
The following describes the embodiments of the present invention in detail with reference to the drawings.
The invention is shown in fig. 1-2, which comprises a specimen bag, wherein the specimen bag is composed of an inner layer steel wire net bag 3 and an outer layer bag body 2, the outer wall of the steel wire net bag is attached to the inner wall of the bag body, the upper edge of the steel wire net bag is inwards or outwards rolled to form an annular opening, the upper edge of the bag body is inwards rolled and wrapped on the periphery of the annular opening of the steel wire net bag to form an opening of the specimen bag, a steel wire rope 1 extending out of the bag body is penetrated in the hollow in the annular opening of the steel wire net bag, a groove 4 is arranged between the bottom of the steel wire net bag and the inner bottom surface of the bag body, an attraction pipeline 5 is arranged on the outer side wall of the bag body, the lower opening of the attraction pipeline penetrates through the bottom of the bag body and is communicated with the groove, and the upper part of the attraction pipeline is arranged on the outer wall of the upper part of the bag body.
The two ends of the steel wire rope 1 extend out of the bag body, one end of the steel wire rope is an extension end, and the other end of the steel wire rope is wound on the extension end close to the outer side of the bag body.
The periphery of the extending end of the steel wire rope 1 is sleeved with a guide pipe 6, and the upper opening of the suction pipeline penetrates through the guide pipe and the extending end of the steel wire rope and is connected together.
The outer diameter of the catheter 6 is 1cm.
The bag body 2 is in the shape of a spindle with the height of the highest part in the vertical direction being larger than the length of the longest part in the horizontal direction.
The steel wire net bag 3 is in a spindle shape with the height being greater than the length and the bottom and the mouth being horizontal, and the mesh of the steel wire net bag is in a diamond shape with the height being greater than the length.
The bag body 2 is of a bag structure made of rubber, and the outer wall of the bag body is a smooth surface.
The steel wire net bag 3 is a net bag body made of a vascular guide wire.
When the annular opening of the steel wire net bag 3 is in a closed state, the included angle between the two corresponding side edges of the top is 15-30 degrees, and the included angle between the two corresponding side edges of the bottom is 15-30 degrees.
The maximum stretching outer diameter of the specimen bag at the transverse longest point is 5cm; the sum of the transverse longest point of the specimen bag in the contracted state and the outer diameter of the suction pipeline is less than or equal to 1cm.
The outer diameter of the suction pipe 5 is 3mm.
When the invention is used, the extension end of the steel wire rope is pulled to force the extension direction of the extension end of the steel wire rope, so that the opening part of the specimen bag is in a contracted state, then the extractor of the invention is downwards placed in the poking clamping hole at the wound, then the extension end of the steel wire rope is pushed to the other end of the steel wire rope, so that the opening part of the specimen bag is in an open state, and the specimen to be extracted is placed in the extractor of the invention, and because the invention aims at the stomach (cancer), the large omentum, the colon (cancer), the rectum (cancer), the small intestine, the gall bladder, the pancreas and the gall bladder under the laparoscopic surgery, the specimen is large in volume, so that the extractor of the invention is stretched in transverse dimension, and at the moment, the extractor of the invention is upwards lifted, when the upper enhancement of the extractor reaches the height of the extractor, the height of the extractor is fully unfolded, at the moment, the steel wire net bag is in a spindle shape with the height larger than the length and the bottom and the mouth part being horizontal, the mesh of the steel wire net bag is in a diamond shape with the height larger than the length, the bag body is in a spindle shape with the height at the highest vertical position larger than the length at the longest transverse position, the opening part of the specimen bag is contracted, the blood vessel guide wire of the steel wire net bag also can enable a specimen to be transversely extruded, so that the transverse diameter of the specimen is reduced, the specimen extraction incision can be directly reduced, liquid in the specimen extraction incision can flow downwards into the groove, and the liquid flowing into the groove is sucked away by the suction pipe, so that the specimen is not damaged, and the specimen is not polluted.
The invention ensures the integrity of the specimen as much as possible, is more beneficial to detection, especially tumor specimen, is completely wrapped in the invention and does not pollute the abdominal cavity, in order to avoid the transverse widening of the steel wire net bag, the acute angles of the top and the bottom are 15-30 degrees in the closed state in the design, the middle part of the steel wire net bag is outwards projected, the steel wire net bag is made of vascular guide wires, the steel wire net bag cannot be subjected to severe transverse change when the specimen is filled, the specimen can be well contained in the steel wire net bag due to the design that the middle part is outwards projected, the opening of the steel wire net bag is contracted so as to enable the specimen to slide towards the upper end and the lower end, and the annular opening of the steel wire net bag is tightened so as not to cause the transverse dimension of the steel wire net bag to be projected. When the steel wire net bag is vertically stretched and deformed, the transverse deformation is reduced, so that the steel wire net bag filled with the specimen is easier to take out from the small incision. The lower opening of the suction pipeline is communicated with the groove through the bottom of the bag body, and when the opening of the specimen bag is not completely closed, the specimen can block the opening of the specimen bag, and the liquid is positioned in the groove at the bottom of the bag body, so that a better suction effect can be achieved.
Compared with the prior art, the extractor has the following advantages:
(1) Fully wrapping the specimen, and avoiding the specimen pollution;
(2) The sample volume can be compressed as much as possible, and the sample taking out incision can be indirectly reduced;
(3) The specimen can be stretched, the transverse diameter of the specimen is reduced, and the specimen taking out incision can be directly reduced;
(4) The extractor can be used for laparoscopic surgery (stomach/cancer, omentum, colon/cancer, rectum/cancer, small intestine, gall bladder, pancreas and gall bladder) specimens with wide application range.
The invention is mainly characterized by being used for the sample taking-out link after laparoscopic surgery, being simple and convenient to assemble and take and easy to operate, being capable of reducing the incision for taking out the surgical sample as much as possible and being more suitable for the full-cavity endoscopic surgery.
