Get foreign matter supplementary gasbag

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to an auxiliary air bag for taking foreign matters.

Background

With the development of modern medical technology, the condition of disease, which originally cannot be directly acquired from the disease cause and the disease focus condition, can be inspected on a patient with low or no influence through the existing medical equipment, and the actual condition of the corresponding part in the body of the patient can be accurately acquired. The endoscopic retrograde cholangiopancreatography is a modern medical intervention treatment means, and particularly relates to a technology for inserting a duodenoscope to a descending part of duodenum, finding a duodenal papilla, inserting a contrast catheter into a biopsy pipeline to an opening part of the papilla, and performing x-ray radiography after injecting a contrast agent so as to display a cholangiopancreatography. Because ERCP does not need to be operated, the trauma is small, the operation time is short, the complication is less than that of the surgical operation, the hospitalization time is greatly shortened, and the ERCP is popular with patients. ERCP has achieved great clinical results in a few decades, and has become an important treatment means for pancreatic and biliary diseases today.

Among them, the common one in ERCP is an endoscopic device, which integrates conventional optical, ergonomic, precision mechanical, modern electronics, mathematics, and software into one detecting instrument. A tubular structure with image sensor, optical lens, light source illumination, mechanical device, etc., which can enter the stomach through the mouth or enter the body through other natural orifices. The endoscope tip also has an externally operable jaw that can be extended and rotated within a range and held by the control tip to perform biopsy sampling or foreign body removal. When some foreign matters with larger volume are blocked and treated, the foreign matters are directly clamped and dragged through the existing endoscope forceps, so that the inner wall of the digestive tract is scratched by the sharp part of the endoscope forceps easily, and the more serious problem is caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a protective air bag structure, which expands the digestive tract by different air bag structures arranged outside an endoscope and wraps foreign matters so that the foreign matters are not contacted with the inner wall of the digestive tract as far as possible in the dragging process, thereby achieving the protective effect.

The technical scheme adopted by the utility model is as follows:

in a first aspect, the utility model provides a foreign body taking auxiliary air bag, which is used for expanding and wrapping when a clamp on an endoscope clamps a foreign body, and comprises an expanding air bag and a protecting air bag which are sleeved on the outer wall of the endoscope, wherein the expanding air bag and the protecting air bag supply (or exhaust) air from the outside through pipelines.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Example 1:

the present embodiment discloses a foreign body removal assisting balloon which is used in endoscopic 1 examination and operation of the digestive tract to protect the digestive tract by expanding at a specific position. The foreign body object in the embodiment is mainly stones staying in the digestive tract or in the digestive gland, and can also be used for objects that are accidentally swallowed and choked by bones. Such objects typically have relatively sharp protrusions, which are stuck in a location and cannot be moved further because they are deposited by material or a narrow channel, and the location and other information are determined by external fluoroscopy or direct viewing of the endoscope 1 and then treated by the endoscope 1.

The inner diameter related in the embodiment is mainly a tubular structure, the end part of the inner diameter is at least provided with a camera, a jaw 4 extending opening and a lamp cap, a real-time picture is obtained through the lamp cap and the camera, the jaw 4 is in a wire pulling control mode, the end part of the jaw is always kept in an open state after extending, and the jaw can be clamped after an external operation end acts, so that the effect of dragging foreign matters can be achieved.

The air-bag in this embodiment is a separate structure, as shown in fig. 1-5, which is a one-piece structure having two separate air-bags: an expanding balloon 2 and a protecting balloon 3. Both balloons have a fastening portion which is not malleable and is fastened to a sleeve by means of glue. The sleeve is made of soft extensible material, a plurality of elastic ring bodies are arranged in the sleeve, and the inner diameter of the sleeve is smaller than the outer size of the endoscope 1 under the condition of not being subjected to external force. And the inner wall of the sleeve can be provided with viscose, although the structure is a disposable air bag structure, the inner wall of the sleeve needs to be stably connected with the end part of the endoscope 1, and the stability can be improved by coating the viscose inside the sleeve when the sleeve is sleeved.

Further, the dilatation balloon 2 and the protection balloon 3 have separate chambers, but supply air through the same trachea. The tube is independently arranged outside the endoscope 1 and can be fixed in a winding or gluing way. The air pump is connected with the outside of the trachea, and when the endoscope 1 reaches the corresponding position, the air pump is controlled to expand.

It is worth to say that the trachea itself connects the two balloons, and the maximum outer diameter of the dilatation balloon 2 is larger than the maximum outer diameter of the protection balloon 3 under the same air pressure by setting conditions of different balloon positions, orientations of the dilatation material, and thicknesses of the dilatation material.

The protective balloon 3 in this embodiment has a conical configuration, and it can be seen that the balloon is divided into two parts, which fit completely against the surface of the endoscope 1 when not expanded, and which, in addition to having an inextensible anchoring portion at its base and a ring-shaped portion at its top, has a low extensibility. Two larger sectors are arranged between the annular part and the fixed part, wherein the ductility of materials of the inner and outer sectors are the same, and the fabric amount of the inner sector is less than that of the outer sector, so that the protective airbag 3 can expand obliquely after gas injection.

The soft material originally attached to the surface of the endoscope 1 has a good storage effect, and can move towards the designated direction after being expanded, so that the phenomenon that the soft material firstly contacts the inner wall of the alimentary canal during expansion to block and influence the expansion towards the predetermined direction is avoided. But in actual operation, the adjustment is carried out according to actual conditions. If the inserted digestive tract itself is narrow, even if the dilatation balloon 2 is already in contact with the digestive tract before the protection balloon 3, there may be a case where the surface of the digestive tract is in contact with the surface of the digestive tract as the protection balloon 3 is continuously stretched. At this time, if the protection airbag 3 is folded, the endoscope 1 can be dragged to reciprocate properly to pull out the folded part, and then air supply is continued, so that the corresponding problems can be solved.

It should be noted that the two balloons shown in the figures are attached to the surface of the endoscope 1 in the non-inflated state, and it is defined in the above that the two balloons have the same fixing portions, and the fixing portions are oriented in the same direction, so that the expansion of the protective balloon 3 is oriented in a direction in which the oblique jaws 4 can extend, and the difference in the inner and outer expansion is achieved by the difference in the material extension length.

In addition, the figures do not show the foreign matter and the actual digestive tract, and the forceps 4 in the figures is in an over-extended state, so that the foreign matter can enter the protective air bag 3 when the foreign matter is clamped again.

Example 2:

the present embodiment also discloses a foreign matter fetching auxiliary airbag, which is different from embodiment 1 in that the two-part airbag structure included in the present embodiment has different arrangement modes, specifically as follows:

this embodiment includes two separate bladder configurations: an expanding balloon 2 and a protecting balloon 3. Each air bag is provided with an independent fixing part and an expansion part, wherein the fixing parts of the two air bags are of annular hard plate structures, and included angles are formed between the fixing parts and the expansion parts, and the included angles range from 30 degrees to 60 degrees. The two fixing parts are fixed on the same fixing ring and form an integrated structure with the fixing ring.

The inner part of the fixing ring is provided with a soft anti-slip material, and the inner diameter of the structure is smaller than the outer diameter of the end part of the endoscope 1, so that the fixing ring can have certain surface pressure when being sleeved on the end part of the endoscope 1 and can realize a stable fixing effect by matching with the soft anti-slip material.

Different from the embodiment 1, the two air cushions in the embodiment do not need to be provided with special materials and structures, because the orientations of the fixing parts are different, the expansion directions are different when the endoscope 1 is inflated, the expansion air bag 2 directly expands outwards in the direction perpendicular to the axis of the endoscope 1, and the protection air bag 3 can expand towards one side of the clamp 4 and wrap corresponding foreign matters.

Further, the two air bags are provided with independent chambers which are communicated by two pipelines for air supply. Different from embodiment 1, the effect that inflation control can be better respectively is through control the inflation volume for expansion gasbag 2 can expand the alimentary canal in corresponding region to certain width completely, then makes protection gasbag 3 expand again, and the inflation volume only need satisfy with the partial parcel of foreign matter direction of advance can.

The present invention is not limited to the above-described alternative embodiments, and various other forms of products can be obtained by anyone in light of the present invention. The above detailed description should not be taken as limiting the scope of the utility model, which is defined in the claims, and which the description is intended to be interpreted accordingly.
