The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. "beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1 to 3, a laparoscopic extractor according to a preferred embodiment of the present invention includes a base 100, a flexible tube 600, a first elastic strip 200, a second elastic strip 300, an extraction bag 400, and a tightening rope 500; the flexible tube 600 has a first opening 610 and a second opening 620; one end of the first elastic strip 200 is mounted on the base 100 and the other end thereof penetrates into the flexible tube 600 through the first opening 610; a first friction force is formed between the first elastic strip 200 and the flexible tube 600; one end of the second elastic strip 300 is mounted on the base 100 and the other end thereof penetrates into the flexible tube 600 through the second opening 620; a second friction force is formed between the second elastic strip 300 and the flexible tube 600; the bag 400 has a bag mouth 410; a first sliding seat 700 and a second sliding seat 800 are arranged on the edge of the bag opening 410, the first elastic strip 200 is arranged on the first sliding seat 700 in a sliding manner, and the second elastic strip 300 is arranged on the second sliding seat 800 in a sliding manner; a tightening rope 500 is mounted on the bag 400 and is used for tightening the bag opening 410; the tightening rope 500 is in a ring shape, and a connection end 510 detachably connected to the first elastic strip 200 is formed on the tightening rope 500.
In this embodiment, when in use, the object-taking bag 400 is inserted into the body through the hole site opened on the body, wherein the first elastic strip 200 and the second elastic strip 300 are extruded and deformed by the hole site, so that the opened object-taking bag 400 can enter into the body through the hole site.
After the tissue to be taken out is loaded into the fetching bag 400, force is applied to the base 100 to pull out the fetching bag 400 outwards, and in the pulling-out process, the first friction force and the second friction force are gradually increased, so that the moving trends of the flexible tube 600 and the first elastic strip 200 and the second elastic strip 300 are gradually increased until one of the first friction force and the second friction force is converted from static friction force to dynamic friction force, so that one of the first elastic strip 200 and the second elastic strip 300 is separated from the flexible tube 600, and at the moment, the friction force between the other of the first elastic strip 200 and the second elastic strip 300 and the flexible tube 600 is suddenly reduced and can be connected together through the friction force of the sudden reduction; then, the first elastic strip 200 and the second elastic strip 300 are no longer limited by the flexible tube 600 and can slide out of the first sliding base 700 and the second sliding base 800 respectively, and the flexible tube 600 slides out together with the first elastic strip 200 or the second elastic strip 300; then, the tightening string 500 is tightened so that the mouth 410 of the bag 400 is tightened and the tissues contained in the bag 400 do not fall.
In this embodiment, the first elastic strip 200 and the second elastic strip 300 can open the object-fetching bag 400 in vivo, so as to facilitate the tissue to be fetched; the first elastic strip 200 and the second elastic strip 300 can be detachably connected through the flexible tube 600 and can be taken out to cancel the opening of the fetching bag 400; meanwhile, the arrangement of the tightening rope 500 enables the bag mouth 410 of the bag 400 to be tightened after being separated from the first elastic strip 200 and the second elastic strip 300; therefore, the extractor of the laparoscope of the embodiment does not need to be limited to be used when the operation is about to be finished, and can be used in any process of the operation without occupying the operation volume and the risk of diffusion.
It should be noted that although the flexible tube 600 may fall off from the first elastic strip 200 and the second elastic strip 300 at the same time, so that the flexible tube 600 loses support and falls off in the body, thereby causing an operation accident, after the flexible tube 600 is separated from one of the first elastic strip 200 and the second elastic strip 300, the friction force with the other of the first elastic strip 200 and the second elastic strip 300 can be instantly reduced by a small value, so that the probability that the flexible tube 600 falls off from the first elastic strip 200 and the second elastic strip 300 at the same time is small, and even if the flexible tube 600 falls off, an operator can know whether the flexible tube 600 falls off through whether the flexible tube 600 is connected to the first elastic strip 200 and the second elastic strip 300, thereby taking measures and treatment rapidly.
Further, a sheet body 210 is arranged on the first elastic strip 200 between the bag 400 and the base 100; the sheet body 210 is provided with a through hole 211, and the connecting end 510 penetrates through the through hole 211 and is bonded on the sheet body 210. In this embodiment, the connecting end 510 of the tightening rope 500 is bonded to the sheet body 210, so that the first elastic strip 200 can synchronously drive the tightening rope 500 to tighten when sliding out; after tightening, the applied force to the first elastic strip 200 suddenly increases, breaking the bond at the connecting end 510, leaving the tightened tightening cord 500 in the body.
Preferably, the connecting end 510 is broken or cut after the sheet 210 slides out of the body, so that the connecting end 510 outside the body can be directly pulled when the object fetching bag 400 is taken out, and the operation is convenient.
Further, the first slider 700 is a first strap forming a first hole with the edge of the bag opening 410, and the second slider 800 is a second strap enclosing a second hole with the edge of the bag opening 410. In this embodiment, the first strap and the second strap are both made of flexible materials and are suitable for being disposed at the edge of the bag opening 410 of the object-taking bag 400.
Further, the diameter of the first hole is larger than that of the flexible tube 600, and the diameter of the second hole is larger than that of the flexible tube 600, so that the flexible tube 600 can smoothly slide out of the first slide carriage 700 or the second slide carriage 800.
Further, the number of the first belt body is plural, and the number of the second belt body is plural, so as to provide good fixing action for the first elastic strip 200 and the second elastic strip 300, respectively.
Further, the flexible tube 600 is located on a side edge of the bag opening 410 away from the base 100. On the one hand, the first elastic strip 200 and the second elastic strip 300 can better open the bag 400, and on the other hand, the outward pulling acting force applied to the first elastic strip 200 and the second elastic strip 300 can better form a first friction force and a second friction force as reaction forces, so that the first friction force and the second friction force can be rapidly improved, and the flexible tube 600 and the first elastic strip 200 or the second elastic strip 300 fall off.
Further, the first elastic strip 200, the second elastic strip 300 and the base 100 are fixedly connected, so that the base 100 can stably drive the first elastic strip 200 and the second elastic strip 300 to apply an acting force when being far away from the bag 400.
Further, the flexible tube 600 is a rubber tube.
In the description of the present specification, reference to the description of "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention.
