Description

Stomach foreign matter remove device

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a device for taking out foreign bodies in a stomach.

Background

The foreign body is taken out from the inside of the human body through a foreign body extractor, and the foreign body can be an object accidentally swallowed into the human body or a cutting object of the redundant tissue generated in the human body. The forceps are structured into two stitches, so that soft tissues in a foreign body or some soft foreign bodies with small volume or soft foreign bodies can be taken out easily only by clamping the foreign bodies, but the foreign bodies are very many in types and different in size, for example, the foreign bodies can be sharp, the foreign bodies are difficult to take out by using the forceps, and even if the foreign bodies can be taken out, the difficulty is quite high. And when the forceps clamp the foreign body to pass through the esophagus, the inner wall of the esophagus is possibly damaged, and secondary damage is brought to a patient. Adopt the stone basket of getting that hyperelastic memory alloy made also to be the foreign matter extractor commonly used except that foreign matter pincers or biopsy forceps, but the current stone basket of getting opens the range less, and is difficult for taking out to great foreign matter, and in addition, the space roll-off between the basket is followed easily to less foreign matter taking out in-process, and the foreign matter is picked up comparatively difficultly.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of the existing foreign body forceps or biopsy forceps and the stone-taking basket, the utility model discloses a device for taking out foreign bodies from the stomach, which has the advantages of large opening angle, soft material structure, no damage to soft tissues, suitability for taking out foreign bodies with different sizes, convenience in operation and the like.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a stomach foreign matter remove device, includes casing, inside sleeve, push-and-pull rod, balancing piece, elastic wire, diaphragm, inside sleeve is located in the middle of the casing, and one end is fixed bottom the casing, and the other end stretches out casing upper portion, inside the push-and-pull rod was located inside the inside sleeve, one end was fixed with the balancing piece, and the other end is equipped with the handle, the balancing piece overlaps outside the inside sleeve, can slide from top to bottom along inside sleeve outer wall under the push-and-pull rod drives, the balancing piece bottom is equipped with the fixed hook, elastic wire one end is connected on the fixed hook, casing bottom intermediate position is equipped with the receipts silk hole, the elastic wire other end passes the receipts silk hole, the outside at the elastic wire of diaphragm cladding.

Furthermore, the number of the elastic wires is 4-8, the elastic wires are arc-shaped in a natural state, the bottom of the elastic wires is provided with an anti-skid ball, and the anti-skid ball is provided with anti-skid stripes.

Further, the wire receiving hole is the same as the inner sleeve in size.

Furthermore, the thickness of the diaphragm is 0.5-1mm, and the width of the diaphragm is 1.5-2 times of the distance between two adjacent elastic wires 5.

The utility model discloses a device for taking out foreign matters in a stomach, which adopts a push-pull rod to connect a balance block, so that the balance block can slide up and down on the outer wall of an inner sleeve, and the balance block can stably drive an elastic wire fixed at the lower part of the balance block to enter and exit the inner sleeve along a wire collecting hole. Before using, the elastic wire draws in inside sleeve, after foreign matter remove device stretched into the stomach, push away the handle, the balancing piece slided downwards under the push-and-pull rod drives, the elastic wire that is fixed in the balancing piece bottom passes and receives a hole, resume original arc state under the elastic action, the elastic wire afterbody opens, snatch the foreign matter through anti-skidding ball and pull the handle after to, it is closed to receive elastic wire afterbody under the restriction of a hole, seal the foreign matter between the elastic wire, the diaphragm can prevent tiny foreign matter landing, can prevent simultaneously that sharp-pointed foreign matter from taking out in-process fish tail esophagus, conveniently thoroughly clear away the foreign matter.
