Description

Bronchoscope auxiliary examination tool

Technical Field

The utility model belongs to the field of bronchus, and relates to a bronchoscope auxiliary examination tool.

Background

The bronchoscope is suitable for observing pathological changes of lung lobes, segments and subsegments of bronchus, biopsy sampling, bacteriology and cytology examination, and can be used for photographing, teaching and dynamic recording in cooperation with a TV system. The bronchoscope is attached with a biopsy sampling mechanism, can help to discover early lesions, can carry out in vivo and vitro surgical operations such as polyp removal and the like, and is a good precision instrument for the research of bronchial and lung diseases, postoperative examination and the like.

Currently, a fiberoptic bronchoscope generally includes an operating portion, a light guide connecting portion, and an insertion tube, the operating portion having an eyepiece portion thereon, the operating portion and the light guide connecting portion being connected through a light guide hose, the insertion tube being connected to the operating portion at one end, the insertion tube being a bent portion at a front end at the other end. When the novel throat inserting tube is used, a patient needs to lie down, the head of the patient needs to be lifted backwards as much as possible, so that the throat channel is smooth, the inserting tube is convenient to insert, the discomfort of the patient is enhanced by the aid of the operation mode, the patient cannot necessarily do the action aiming at the patients with neck injuries, follow-up work is difficult to complete smoothly, and therefore related structures are necessary to be improved and innovated.

Disclosure of Invention

The utility model aims to provide a bronchoscope auxiliary examination tool aiming at the problems in the prior art, the examination tool is suitable for special patients, discomfort of the patients is reduced, and the problems that the existing bronchoscope is inconvenient for the patients with neck injuries to use, the discomfort of the patients is strong and the like are solved.

The purpose of the utility model can be realized by the following technical scheme: bronchoscope appurtenance, including the body, body one end is the link, and the other end is crooked end, its characterized in that, the cover is equipped with the guide on the body, set up in the guide and wear to establish the passageway, wear to establish the passageway and run through the guide both ends, the guide is in can follow body endwise slip on the body, it keeps off the edge to have on the body, keep off along the restriction guide one direction motion, it has the fillet to have the holding surface and the L shape holding surface corner that the cross-section is L shape on the guide.

In the inspection tool, the connection end of the pipe body is connected to the operation portion. The effect of guide is to make the body form the bending and stretch into the angle, and human throat department has an obvious corner, and when the body stretched into, in order to can smoothly stretch into, just need the patient with the head back to certain angle, this is extremely unfavorable for the injured patient of neck. Through the guide design, make patient can form the turning in throat department under the condition of the head of pitching less or not, make stretching into that the body can be convenient fast, the guide links to each other with the body, insert to relevant position along the body during use, the patient opens one's mouth when inserting, but operating personnel direct observation throat corner, with the guide arrange the corner in can, keep off along being the downstream in order to restrict the guide, prevent that the guide from breaking away from the body. The L-shaped supporting surface acts on the corresponding position of the throat to form a clamping structure, and the fillet structural design accords with the real structure of a human body, so that the guide piece can be smoothly attached and stably fixed.

Among the supplementary inspection tool of foretell bronchoscope, inspection tool still includes a spacing section of thick bamboo, but spacing section of thick bamboo cover is located on the body and is slided, spacing section of thick bamboo is including the spacing portion of radial extension and the interlock portion that is used for the interlock, interlock portion and spacing portion link to each other.

The limiting cylinder is used for opening the mouth part to prevent a patient from directly biting the tube body, the limiting part is positioned outside the mouth and can prevent the limiting cylinder from entering the mouth, the patient bites the biting part, and the tube body can be freely retracted and pulled.

In the bronchoscope auxiliary inspection tool, the limiting cylinder is further provided with a flaring portion, one end of the flaring portion is connected with the occlusion portion, and the end of the flaring portion is flared towards the other end.

The flaring portion is used for preventing the limiting barrel from falling out easily to form a limiting effect, and meanwhile, the flaring structure facilitates the direction change of the pipe body in the process of penetrating and setting, so that more spaces are provided for movement of the pipe fitting.

In the bronchoscope auxiliary examination tool, the minimum inner diameter of the limiting cylinder is larger than the inner diameter of the penetrating channel.

Namely, a larger gap is arranged between the limiting cylinder and the tube body, so that the limiting cylinder does not block the motion of the tube body.

In the bronchoscope auxiliary examination tool, the tube body and the guide piece are made of the same material.

The guide is a disposable tool.

In the bronchoscope auxiliary examination tool, the limiting cylinder is made of plastic.

The limiting cylinder is a disposable tool and is generally made of polyethylene materials.

Compared with the prior art, the bronchoscope auxiliary examination tool has the following advantages:

1. this bronchoscope appurtenance passes through the guide design, makes patient can form the turning in throat department under the condition of the head of raising little or not raising the head, makes the body can be fast convenient stretch into.

2. The L-shaped supporting surface acts on the corresponding position of the throat to form a clamping structure, and the fillet structural design accords with the real structure of a human body, so that the guide piece can be smoothly attached and stably fixed.

3. This bronchoscope appurtenance passes through a spacing section of thick bamboo design, realizes that patient props the mouth, prevents that patient from biting the body.
