Abstract

The utility model discloses a bronchial foreign body front plugging type kagitori clamp which consists of a extraction steam turbine tube (1), a hand-held handle (2). The right side of the extraction steam turbine tube's (1) front orifice is fixedly arranged with a front jaw (4), the front jaw's (4) right wall is pasted with an elastic chamber (5), the middle part and the bottom part of the front jaw (4) are respectively fixed with a middle drawing wire (6) and a bottom drawing wire (7), the elastic chamber's (5) bottom part is connected with a gas filled tube (8), a plate strip (11) is inserted into the left side of the extraction steam turbine tube's (1) lumen, the plate strip's (11) front end is fixedly arranged with a rear jaw (13) which can be screwed out. The bronchial foreign body front plugging type kagitori clamp can keep being at one axis when inserted into a trachea by making the front jaw and the rear jaw move through the drawing wires, can clamp or kagitori from the front, rear side of a foreign body, or can shore up in the foreign body cavity and fixedly draw out the foreign body when used to clamp the foreign body, thus the utility model has a flexible clamping according to different foreign bodies, is uneasy to slip, the foreign body particles which are clamped to crush cannot enter the bronchus, thus the use is more safe.

Description

Stifled formula hooks up pincers before the foreign body in bronchus

Technical field

This utility model relates to a kind of medical apparatus and instruments, and stifled formula hooks up pincers before particularly a kind of foreign body in bronchus.

Background technology

Stopping up foreign body in trachea and the bronchus is commonly encountered diseases, and particularly the child is more common.The foreign body kind of stopping up is a lot, and shape differs, and soft or hard degree difference causes certain difficulty for the taking-up foreign body.Operating forceps gripping foreign body commonly used clinically during with operating forceps gripping foreign body, puts in operating forceps in the bronchus in the trachea lens barrel, after observing foreign body by tracheascope, with the mirror chamber gripping foreign body of operating forceps by tracheascope.In operation, existing weak point is: the one, for smooth and foreign body hard, be not easy to clamp, because the clamp mouth forward, in clamping process, folded foreign body is easily to front slide, if chucking power is excessive,, also may press from both sides broken for hard and crisp foreign body, press from both sides the tiny foreign particles in broken back and also can enter in the tiny bronchus, make taking-up difficulty more; The 2nd, for plastics loudspeaker class foreign body,, when the child blows and plays, suck easily as balloon plastics loudspeaker, skin doll type toy plastics loudspeaker etc., this type of foreign body easily and bronchial wall be close to, often seamless, operating forceps is difficult for gripping; The 3rd, after chela opens, because of outside subtended angle is arranged, thus be difficult between foreign body and tracheal wall, inserting, and stab tracheal wall easily.

Summary of the invention

The purpose of this utility model is to provide a kind of above the deficiencies in the prior art that overcome, can from the inside and outside both direction gripping of foreign body or hook up and prevent foreign body to front slide and before being difficult for stabbing the foreign body in bronchus of tracheal wall stifled formula hook up pincers.

For reaching above purpose, the technical scheme that this utility model adopted is: stifled formula hooks up pincers before this foreign body in bronchus, by extraction tube, hand holding handle constitutes, it is characterized in that fixing fore paw by rotating pin on the right side of the extraction tube front end mouth of pipe, pasting elastic bag on the right side wall of fore paw, fix stringy upper end, middle part at the middle part of fore paw, fix stringy upper end, bottom in the bottom of fore paw, the tube chamber of extraction tube is all passed in stringy lower end, middle part and stringy lower end, bottom, stretch out from the rear end mouth of pipe of extraction tube, middle part wire drawing by the pulling fore paw, fore paw is outwards screwed out, with axially having a certain degree of extraction tube, as plumbness, bottom wire drawing by the pulling fore paw, can make fore paw parallel with the axis of extraction tube, be convenient to insert in the slit between foreign body and the tracheal wall, connect gas tube in the bottom of elastic bag, gas tube passes the tube chamber of extraction tube, stretch out from the rear end mouth of pipe of extraction tube, connect inflatable ball in the outer end of gas tube, elastic bag is located at the outside of fore paw, interleaving fashionable from the slit between foreign body and the tracheal wall, can avoid stabbing tracheal wall, simultaneously, shaking property expansion by the Artificial Control elastic bag, slit between foreign body and the tracheal wall is strengthened gradually, the front side that fore paw is inserted into foreign body progressively, on the extraction tube sidewall of fore paw back-out direction, establish axial slide, a stripe board is inserted in the left side in the extraction tube tube chamber, leading section in stripe board is fixed rear solid end by rotational pin, fix an arc flexure strip in the left side of rear solid end, when rear solid end and stripe board all are in the tube chamber of extraction tube, rear solid end is not outwards upset under the constraint of extraction tube tube chamber, before, rear solid end all is in the axis parastate with extraction tube, can insert this moment from the tracheascope intracavity, after the insertion, insert fore paw the slit between foreign body and tracheal wall, after fore paw was inserted foreign body, the middle part wire drawing of pulling fore paw, fore paw is screwed out left, become and the vertical state of extraction tube, simultaneously, elastic bag is inflated, make the trachea chamber shutoff of elastic bag, prevent that foreign body from sliding, or prevent that the broken back of foreign body folder particle from falling into bronchioles the foreign body front end, promote stripe board again, rear solid end is entered in the axial slide, after rear solid end enters in the axial slide, under the effect of arc flexure strip, rear solid end overturns outside axial slide, become 70-80 degree angle with stripe board, form clamp port thereby make between fore paw and the rear solid end, then, continue to promote forward stripe board, before making, rear solid end is before foreign body, rear side clamps foreign body, and spur the middle part wire drawing of fore paw this moment again, and drive extraction tube simultaneously, foreign body can take out, if the horn-like foreign body of plastics is taken out, fore paw can be stretched in the plastics horn chamber middle part wire drawing of pulling fore paw in horn mouth, fore paw is rotated, horizontal being stuck in the plastics horn chamber continued the middle part wire drawing of pulling fore paw, and the horn-like foreign body of plastics is proposed.This utility model is also implemented by following measure: described rear solid end is fixed on by rotational pin in the front end prong of stripe board, and rear solid end is from the length of one section to the rear solid end rear end of rotational pin, so that rear solid end is when producing, keeps 70-85 degree angle to be advisable with the axis of extraction tube; The middle part wire drawing and the rear end wire drawing of described fore paw are finer wire, and diameter is 0.5mm.

The beneficial effects of the utility model are: because forward and backward pawl is movable, to the trachea interpolation time, can keep on an axis, so insert in the trachea easily, and forward and backward pawl can or hook up or prop up fixedly from the foreign body intracavity and pull from the forward and backward side gripping of foreign body, so it is flexible to different foreign body grippings, simultaneously also be not easy to make the foreign body slippage, press from both sides broken foreign particles and also be not easy to enter bronchus, use safer.
