Description

Foreign matter extractor

Technical Field

The utility model relates to a foreign matter extractor.

Background

The department of otorhinolaryngology is mainly used for diagnosing and treating diseases related to ears, nose and throat.

We often can meet the patient that the foreign matter got into the auditory canal at the in-process of receiving a doctor, to this type of patient, traditional processing mode adopts a tweezers to carry out the centre gripping, but when the centre gripping through tweezers, need apply great clamping force, often can lead to the foreign matter to deviate from, need a lot of centre gripping just can accomplish and get the thing to in actual operation, tweezers have the pointed end, very probably cause the damage of auditory canal.

Based on the problems, the foreign body extractor capable of avoiding damage of the auditory canal and effectively clamping the foreign body is designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a foreign matter extractor that can avoid the damage of duct, simultaneously can effective centre gripping foreign matter is provided.

The utility model discloses a realize through following technical scheme:

a foreign body extractor comprises a probe tube which is in a cone-shaped structure, the diameter of the probe tube is gradually reduced towards the left side, a hand-held tube is processed at the right end of the probing tube, the hand-held tube and the probing tube are of an integrated structure, a movable rod is inserted in the probing pipe, a clamping piece is arranged on the left side of the movable rod, the clamping piece is provided with two claw parts, a clamping opening for clamping foreign matters is formed between the two claw parts, a tapered clamping end is arranged on the inner side of the claw part, a slope-shaped stress surface is formed on the outer side of the claw part, an annular acting ring is arranged on the inner wall of the probing pipe, when the movable rod moves to the right side, the acting ring acts on the stress surface, the distance between the two claw parts is reduced, and the right end of the movable rod extends to the outside of the handheld pipe.

Preferably, the outer wall of the hand-held tube is provided with an annular groove which is convenient to hold, and a knurled part is processed in the annular groove.

Preferably, the right end of the movable rod extends outwards to the outside of the handheld tube to form a handle, a spring is sleeved on the movable rod, the spring acts between the handheld tube and the handle, and under the action of the spring, the movable rod moves towards the right side to drive the two claw parts to move to the inner side of the probing tube; the effect of above-mentioned structure lies in, when we are through two claw portions centre gripping foreign matter, can draw in the local income of the foreign matter of centre gripping to exploring intraductal through the resilience of spring, directly outwards pull out handheld pipe this moment can.

Preferably, the left end of the claw part is rounded.

Preferably, the wire diameter of the spring is 0.4 mm-0.8 mm.

The utility model has the advantages that: adopt in exploring the pipe and insert to the duct in this product, can avoid and the duct between sharp-pointed contact, avoid causing the damage of duct, can realize the centre gripping of foreign matter through two claw portions to after the centre gripping, can retract to exploring intraductal, when taking out, the foreign matter can be taken out once, and the operation is comparatively simple, and comparatively safe, be fit for using widely.
