Description

Alimentary canal foreign matter remove device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a alimentary canal foreign matter remove device.

Background

Foreign bodies in the stomach are common urgent diseases in internal medicine. Generally, the foreign body is smooth, spherical or flat, and it is not easy to take out the foreign body smoothly through an endoscope in a limited space of the digestive tract, which may take a lot of time and surgical treatment if necessary, thereby increasing the risk and pain of the patient.

With the development of endoscope technology, part of foreign bodies in the alimentary canal can be taken out by using a foreign body clamp or a snare under the guidance of a laryngoscope and a gastroscope, but the existing technology is still difficult to handle for some specially-shaped foreign bodies, and the problem of difficult taking out exists; for some foreign bodies with sharp one end or two ends, the foreign bodies are easy to scratch the esophagus or the throat when taken out; for the corrosive foreign matters inside, the damage of the object in the grabbing process can cause secondary damage to the digestive tract.

Therefore, it is necessary to design a device suitable for taking out foreign matters of different shapes and materials, so as to shorten the time for taking out the foreign matters, relieve the pain of patients and reduce the damage of the foreign matters to the digestive tract.

Disclosure of Invention

In order to solve the deficiencies in the prior art, the utility model aims to provide a alimentary canal foreign matter remove device, the device can take out the foreign matter of different shapes smoothly, takes out the in-process and forms the parcel to the foreign matter, avoids the damage of foreign matter, avoids foreign matter fish tail alimentary canal, alleviates patient's misery.

The utility model provides a technical scheme that its technical problem adopted does:

the device for taking out the foreign matters in the digestive tract comprises an operating mechanism, a clamp rod, a protective cover and a clamping mechanism which are sequentially arranged, wherein the operating mechanism comprises a control handle, a pull ring and a guide rope, the pull ring is arranged on the control handle, the upper end of the guide rope penetrates through an installation hole in the control handle and is installed on the pull ring, and the other end of the guide rope penetrates through an inner cavity of the clamp rod and is connected with the pull rod positioned in the cavity of the clamp rod; the protective cover is connected with the front end of the clamp rod; the forceps taking mechanism comprises four foreign body forceps, connecting rods and springs, the foreign body forceps are hinged through the connecting pieces, included angles between the four foreign body forceps are 90 degrees, the foreign body forceps are connected with the outer body wall of the pull rod through the connecting rods, and the two opposite connecting rods are connected through the springs. In the foreign body forceps taking process, the pull rod is pushed forwards, the connecting rod gradually extends out, the spring expands to drive the foreign body forceps to open, the forceps taking of the foreign bodies is carried out, when the forceps taking is carried out, the four foreign body forceps can clamp the foreign bodies from four directions, the pull rod is pulled, the connecting rod retracts into the cavity of the forceps rod, the spring is compressed, the two opposite foreign body forceps are folded, the foreign bodies are clamped, the four foreign body forceps are taken from the four directions, the spherical and irregular foreign bodies can be smoothly clamped, and the forceps taking time is shortened; the pull rod is continuously pulled after the forceps are taken out, so that the foreign body forceps are completely fallen into the protective cover, the foreign bodies can be prevented from falling outwards, the foreign bodies can be wrapped, and the alimentary canal can be prevented from being scratched by the foreign bodies.

Furthermore, a through hole matched with the pull rod is formed in the front end face of the clamp rod, symmetrical blind holes are formed in the side surface body wall of the front end of the clamp rod, and a sliding block which penetrates through the blind holes and is in sliding connection with the blind holes is arranged on the pull rod. The blind hole and the sliding block can limit the moving direction of the pull rod, so that the movement of the pull rod in the left and right directions is avoided, and the clamping process is smoother.

Further, when the slide block moves to the foremost end, the connecting rod extends out of the clamp rod, and the foreign matter clamp extends out of the protective cover; when the slide block moves to the rearmost end, the foreign matter pliers are all arranged in the protective cover. The length of blind hole is the mobilizable scope of slider, and the blind hole plays spacing effect to the slider, injects the maximum distance of the backward pulling of foreign matter pincers when guaranteeing that foreign matter pincers can all expose the safety cover, guarantees to take out inside the in-process foreign matter pincers fall on the safety cover.

Furthermore, the front end of the foreign body forceps is a right triangle, and the bottom of the hypotenuse of the right triangle and the upper end face of the foreign body forceps form an inwards-concave arc-shaped groove. The structure of right angled triangle can make things convenient for the clamp of getting the foreign matter, and the foreign matter after getting can fall in the arc wall along triangle-shaped's hypotenuse, and the arc wall can form the protection to the foreign matter when blockking the foreign matter, avoids the foreign matter because of the space is too little broken, ensures the integrality of foreign matter.

Furthermore, the side surface of the protective cover is an inwards concave arc-shaped groove. The safety cover can wrap up the foreign matter, avoids the dysmorphism foreign matter to scrape and hinders the alimentary canal, also can avoid the foreign matter to fall outside once more taking out the in-process simultaneously.

Compared with the prior art, the invention has the beneficial effects that: the device is got to the foreign matter from four directions pincers, and consequently the pincers that can be quick get spherical, irregularly shaped foreign matter, reduce the foreign matter and take out the time, alleviate patient's misery, get the foreign matter at pincers after, the foreign matter falls in the arc wall of foreign matter pincers, avoids damaging and falls outward, and the foreign matter pincers are stretched to the safety cover afterwards, get up the foreign matter parcel, avoid the in-process fish tail that takes out to the alimentary canal.
