All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the embodiment 1, as shown in fig. 1 and 2, the circular foreign body extractor comprises 3 pulling belts 1 made of natural rubber or silica gel and 3 pushing rods 3 made of metal, wherein the pulling belt 1 in the middle is connected with the pulling belts 1 on two sides through a connecting belt 2 made of natural rubber, so that the whole has certain crimping property, the pulling belt 1 is close to the inner end, namely, one side of the end which needs to be deep into the body is provided with an air bag structure 1.1, the air bag structure 1.1 is realized by making the same side part of the pulling belt 1 thinner, namely, under the same pressure condition, the air bag structure 1.1 is firstly expanded under the pressure, and then an acting point is formed on the inner side of the foreign body; the outer side end of the traction belt 1 is provided with a hollow conduit structure (not shown in the figure), the hollow conduit is communicated with the air sac structure 1.1, and the hollow conduit is used for injecting liquid or gas into the air sac structure 1.1 through the hollow conduit on one hand, and is used for inserting a push rod 3 in the operation process on the other hand, so that the traction belt 1 is assisted to smoothly enter a human body.

Embodiment 2, as shown in fig. 2 and fig. 3, the circular foreign body extractor comprises 6 traction belts 1 made of natural rubber or silica gel and 6 pushing rods 3 made of metal, wherein the traction belts 1 in the middle are connected with the traction belts 1 on two sides through connecting belts 2 made of natural rubber, so that the whole is provided with certain crimping property, the traction belts 1 arranged at two ends are crimped and then are extruded by the side walls of anorectum when in use, and a certain centripetal force is kept, so that the later-stage airbag structure 1.1 can be extruded towards the center after being expanded. The traction belt 1 is close to the inner end, namely, one side of the end which needs to be penetrated into the body is provided with an air bag structure 1.1, the air bag structure 1.1 is realized by making the same side part of the traction belt 1 thinner, namely, under the same pressure condition, the air bag structure 1.1 is firstly inflated under the action of pressure, and then the air bag structure 1.1 is used for forming an acting point on the inner side of a foreign body; the outer side end of the traction belt 1 is provided with a hollow catheter (not shown in the figure), the hollow catheter is communicated with the air bag structure 1.1, and the hollow catheter is used for inserting a push rod 3 in the operation process to assist the traction belt 1 to smoothly enter a human body. The middle part of the traction belt 1 is also provided with an inflation tube 5, one end of the inflation tube 5 is connected to the side wall of the middle part of the traction belt 1 and communicated with the hollow conduit, and the other end is provided with a sealing end cover 6. The inflation tube 5 is used for injecting liquid or gas into the air bag structure 1.1, and the sealing end cover 6 is covered to realize sealing after the liquid and gas injection is completed. The liquid or gas injection is more convenient, and simultaneously after the end of the traction belt 1 is deep, the outer side is fastened, and because the setting position of the inflation tube 5 is closer to the air bag structure 1.1, the inflation amount is smaller, and the air bag structure 1.1 is easier to expand.

Illustratively, the inner end of the pulling strip 1 is rounded, forming a rounded end 1.2, thereby making it easier for the pulling strip 1 to be inserted.

The connecting belt 2 is of a hollow structure, and the traction belt 1 and the traction belt 2 are communicated through a hollow conduit, so that the operation of filling gas or liquid is more convenient, and the inflation filling of the air bag structure 1.1 can be completed only through an externally connected inflation tube 5 or the outer side end of the traction belt 1.

Illustratively, the circular foreign matter extractor further comprises a suction cup device comprising a conical suction cup 7 and a vacuum pump, the conical suction cup 7 being connected to the vacuum pump by a connecting tube hose. In the use process, the round foreign matters 4 are pushed in by the traction belt 1 and the like, after the air inflation is completed, the conical sucker 7 of the sucker device stretches into the cylindrical structure formed by the traction belt 1, then after the conical sucker 7 is close to the round foreign matters 4, the vacuum pump is started, the suction force is given to the round foreign matters 4 through the conical sucker 7, the outer side end of the traction belt 1 and the outer side guide pipe of the conical sucker 7 are pulled, and then the round foreign matters 4 are taken out under the cooperation of the conical sucker 7.

Illustratively, the circular foreign body extractor further comprises a clip, and the outer side end of the traction belt 1 is clamped by the clip, so that the operation is more convenient.

The device comprises a working principle and a working process, wherein in the use process, circular foreign matter extractors with different numbers of traction belts are selected according to the required sizes, then a push rod 3 is inserted along the outer end of the traction belt, then the traction belt 1 is curled to form a cylinder shape, the cylinder shape stretches into the anorectal of a human body, and a circular end and an air bag structure 1.1 stretch into the inner measuring end of the circular foreign matter 4 along the edge of the circular foreign matter 4 under the assistance of the push rod 3. Taking out the push rod 3, measuring water injection in the traction belt 1 through the outer side end of the traction belt 1 or the air inflation pipe 5, knotting the outer side of the traction belt 1 after injection is completed, or clamping by a clip to prevent leakage, injecting water through the air inflation pipe 5, sealing the traction belt 1, injecting water, and covering a sealing end cover 6 after injection is completed. If the circular foreign matter 4 is tightly clamped, the conical suction cup 7 is required to extend into the center of the curled traction belt 1, the vacuum pump is started after the conical suction cup 7 butts against the circular foreign matter 4, so that the conical suction cup 7 is adsorbed on the circular foreign matter, then the traction belt 1 and the outer side end of the conical suction cup 7 are pulled, the air bag structure 1.1 is expanded under the action of pressure after water injection or air injection, and therefore the limit is formed at the inner side end of the circular foreign matter 4, and the expansion is at least 3 and the two parts are at the inner side end of the circular foreign matter 4, so that in the external pulling process, the anorectal extrusion is received, the circular foreign matter 4 is extruded to the center completely, and then a strong outward pushing and pulling force is given to the circular foreign matter 4, and meanwhile, the circular foreign matter 4 is smoothly taken out under the traction force of the conical suction cup 7. Simple structure, low manufacturing cost and little harm to human body.

In addition, the application is not only suitable for circular foreign matter 1, to foreign matter simultaneously, also accessible extension connecting band 2 back, directly wraps up foreign matter inboard end and lateral wall after the extension through connecting band 2, then draws outward and accomplishes the foreign matter and take out, and this technical scheme also should belong to the protection scope of this application.
