Abstract

The present utility model belongs to medical instrument, in particular to an endoscope foreign body protector, which is characterized in that a protecting capsule bag, an outer coating catheter, an impelling catheter and a diastolic godet are included. One end of the diastolic godet runs through the impelling catheter and then interwines the wrapping of bottom port of the protecting capsule bag. The other end is connected with the hand hold of the diastolic godet. One end of the impelling catheter is connected fixedly with the protecting capsule bag and the other end connected with the impelling hand hold is broken through the outer coating catheter. The beneficial effect of the utility model is that the protecting device can encapsulate foreign body unusing the annular contraction effect of cardiac or shrinkage phyarynx muscle, and it is no need to worry the happening of foreign body abscission due to the clip looseness or spondylolisthesis of foreign body clamp when the operated endoscope exiting. The adapted expandable protecting device first shrinks to come into upper digestive tract and then takes the foreign body out with the endoscope safely. The utility model is more effective specially to take the foreign body with condyloma edge.

Description

Endoscope's foreign body protector

Technical field

This utility model belongs to medical apparatus and instruments, relates in particular to a kind of endoscope foreign body protector.

Background technology

The upper digestive tract foreign body is clinical common disease, and taking out external through endoscope's safety is the first-selected Therapeutic Method of clinician.Adopted foreign body forceps under the endoscope, snare, foreign body basket to take out foreign body, these methods are only applicable to that volume is little, the foreign body of no sharp edges in the past.The method that adopts the protection valve to help foreign body forceps to get special foreign body is arranged recently.For example: there be the report of a piece of writing about " using the foreign body protector to get the special foreign body of upper digestive tract through scope " " Tianjin medicine " magazine first phase in 2000.This device is owing to need utilize cardia or buccopharyngeal muscle circular contraction effect, and protector could wrap up foreign body, endoscopically withdraw from that idol in the process has since foreign body forceps hold that folder becomes flexible or foreign body takes place and comes off midway in slippage.Therefore be necessary to develop a kind of controllable operating, need not to utilize cardia or buccopharyngeal muscle ring-type to shrink, promptly expandable protector, and can shrink inlet, endoscopically safety is taken out foreign body.

The utility model content

Main purpose of the present utility model is to overcome above-mentioned technological deficiency, and a kind of endoscope foreign body protector is provided, and adopts expandable protector, shrinks earlier to enter upper digestive tract, and endoscopically safety is taken out foreign body; Particularly taking out has the foreign body of sharp edges more effective.

For realizing the purpose of this utility model; the technical scheme that adopts is; a kind of endoscope foreign body protector; it is characterized in that: mainly contain protection capsule bag, overcoat conduit, propulsion bulb, diastole seal wire; described diastole seal wire one end passes propulsion bulb and ring and is through in the bound edge that protection capsule bag goes to the bottom mouthful; the other end is connected with diastole seal wire handle, and propulsion bulb one end and protection capsule bag are affixed, and its other end is connected in the overcoat conduit and with the propulsion bulb handle.

Mouthful size of going to the bottom of described protection capsule bag should be greater than endoscope diameter.

The beneficial effects of the utility model are that this protector needn't utilize cardia or buccopharyngeal muscle circular contraction effect; foreign body can be wrapped up, in the time of also needn't worrying to operate endoscopically withdraw from the process can take place since foreign body forceps hold that folder becomes flexible or slippage makes foreign body obscission midway.Adopt expandable protector, contraction earlier enters upper digestive tract, and endoscopically safety is taken out foreign body; Particularly taking out has the foreign body of sharp edges more effective.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1, endoscope shown in Figure 2 foreign body protector are made up of protection capsule bag 7, diastole seal wire 2, propulsion bulb 4 and overcoat conduit 5.The upper base mouth 6 of protection capsule bag 7 is penetrated with endoscope's insertion tube 9, diastole seal wire 2 one ends pass propulsion bulb 4 and ring and are through protection capsule bag 7 and go to the bottom in mouthfuls 8 the bound edge, the other end is connected with diastole seal wire handle 1, the contraction-diastole of pulling handle 1 may command protection capsule bag 7 inlets 8; Propulsion bulb 4 one ends and protection capsule bag 7 are affixed, and its other end is connected in overcoat conduit 5 and with propulsion bulb handle 3, can adjust and protect capsule bag 7 to move forward and backward along endoscope distal end portion.Be installed in the endoscope before the foreign body protector operation shown in Figure 3.Foreign body protector shown in Figure 4 is followed endoscope and is entered and search out foreign body in the body, sends into foreign body forceps, snare or foreign body basket through the pincers road and holds the folder foreign body.Handle diastole seal wire handle, 1 and propulsion bulb handle 2, open gradually and progressively advance protection capsule bag 7, parcel has been held the foreign body of clamping, shrinks protection capsule bag inlet 8 then, and the endoscopically taking foreign body withdraws from external.Protection capsule bag 7 can be made by anti-cutting woven or rubber, and diastole seal wire handle 1 and propulsion bulb handle 3 can be made endoscopic biopsy jaw type sample handle, also can make simple style action bars.Protection capsule bag bottom opening is designed to walk endoscope, and promptly propulsion bulb can drive and protect the capsule bag to move forward and backward along endoscope distal end portion, and the overcoat conduit 5 of protector and endoscope are parallel fixing, follow the mirror body and freely control protector.Protector is followed endoscope and is entered in the body cavity, at first holds the folder foreign body by foreign body forceps, snare or foreign body basket; Handle diastole seal wire handle 1 and propulsion bulb handle 2 then, protection capsule bag inlet 8 is opened, advance protection capsule bag 7 parcel endoscope distal ends to be held the foreign body of folder simultaneously; Handle diastole seal wire handle 1 vesicula contractilles bag inlet 8 at last, follow endoscope and foreign body is taken out external.The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.

Claims

1. endoscope's foreign body protector; it is characterized in that: mainly contain protection capsule bag, overcoat conduit, propulsion bulb, diastole seal wire; described diastole seal wire one end passes propulsion bulb and ring and is through in the bound edge that protection capsule bag goes to the bottom mouthful; the other end is connected with diastole seal wire handle; propulsion bulb one end and protection capsule bag are affixed, and its other end is connected in the overcoat conduit and with the propulsion bulb handle.
