Abstract
The utility model relates to an anti-stuck device for taking calculuses from a biliary tract. A net basket, an outer tube, a front handle and a rear handle are sequentially arranged on the anti-stuck device from the end portion to the tail portion. The outer tube is connected with the front handle, a casing tube is arranged at the connecting position of the outer tube and the front handle, a soft cable which can slide freely is arranged in the outer tube and connected with the net basket, the other end of the soft cable is connected with a hard cable, and one end of the hard cable is fixedly connected with the rear handle. A guiding wire hole is arranged in the outer tube at the position of a tube opening of the casing tube, and a hard guiding wire can penetrates through the guiding wire hole. When a quite big calculus is stuck in the net basket, and the calculus cannot be broken and cannot be released from the net basket, a doctor can conveniently penetrate the hard guiding wire through the guiding wire hole, the hard guiding wire can reach the calculus from the outer tube, by means of the hard guiding wire, the calculus can be broken or pulled out from the net basket, and therefore the doctor can keep on taking the calculuses out.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of anti-stuck biliary tract stone extraction device.
Background technology
Usually, suffer from the patient of common bile duct, common hepatic duct, left and right sides hepatolith, clinical symptoms such as stomachache, the yellow cellulitis of obstructive and heating usually can occur.For being reluctant to operate or the patient of operation taboo, recurrence after operation, postcholecystectomy etc. being arranged, adopting therapeutic ERCP (promptly taking out treatment through duodenoscope row calculus of bile duct) is first-selection.The normal therapeutic device that adopts is the calculus of bile duct stone extraction basket, and the stone extraction basket pipe sheath that is made of plastics is installed with the tractive steel wire in it, and stone extraction basket handle that links to each other with the tractive steel wire and stone extraction basket formation.
Specifically getting the stone process is: through duodenoscope row retrograde cholangiography, understand position, size and the number of calculus, nipple cuts under the capable again duodenoscope, with stone extraction basket the extrahepatic bile ducts calculus is taken out then.This calculus of bile duct stone extraction basket can only be got the stone treatment to the less patient of calculus of bile duct; Function singleness; If it is bigger to run into patient's calculus, calculus but can not pull after basket put, and calculus is reined in broken again when wanting to abandon getting calculus; The stuck situation in basket of calculus occurs, come no small misery to patient easily.
The utility model content
The technical problem that this utility model will solve is: overcome the deficiency of prior art, a kind of anti-stuck biliary tract stone extraction device is provided, solve the doctor in getting some bigger calculus processes, the stuck phenomenon in basket of calculus occurs.
This utility model solves the technical scheme that its technical problem adopted: a kind of anti-stuck biliary tract stone extraction device; Be provided with basket, outer tube, front hand grip and back handle by the end successively to afterbody; Described outer tube is connected with front hand grip; The junction of said outer tube and front hand grip is provided with protecting pipe, is provided with the soft drawn rope that can be free to slide and be connected with basket in the described outer tube, and the other end of said soft drawn rope is connected with the hard draw rope; One end and the back handle of hard draw rope are fixedly connected, and are positioned to offer on the outer tube at protecting pipe mouth of pipe place to be used for the thread eye that stiff guide wire passes.
Furtherly, described thread eye aperture is provided with the port lid that makes the thread eye sealing.
Furtherly, the length of said protecting pipe is 1～10cm.
The beneficial effect of this utility model is: this utility model relates to a kind of anti-stuck biliary tract stone extraction device; On the outer tube that is positioned at protecting pipe mouth of pipe place, offer and be used for the thread eye that stiff guide wire passes, bigger calculus is stuck in basket when occurring, and calculus is reined in not broken when from basket, not discharging again; Can make things convenient for the doctor in thread eye, to penetrate stiff guide wire; Stiff guide wire arrives calculus from outer tube, through stiff guide wire calculus is smashed to pieces perhaps calculus is transferred to from basket, thereby let the doctor continue to get stone.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Wherein: 1, basket, 2, outer tube, 3, protecting pipe, 4, front hand grip, 21, thread eye, 22, port lid.
The specific embodiment
Combine accompanying drawing that this utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of this utility model in a schematic way, so it only shows the formation relevant with this utility model.
A kind of anti-stuck biliary tract stone extraction device shown in Figure 2 like Fig. 1; Be provided with basket 1, outer tube 2, front hand grip 4 and back handle by the end successively to afterbody, outer tube 2 is connected with front hand grip 4, and outer tube 2 is provided with protecting pipe 3 with the junction of front hand grip 4; Be provided with the soft drawn rope that can be free to slide and be connected in the outer tube 2 with basket 1; The other end of soft drawn rope is connected with the hard draw rope, and an end and the back handle of hard draw rope are fixedly connected, and is positioned to offer on the outer tube 2 at protecting pipe 3 mouth of pipe places to be used for the thread eye 21 that stiff guide wire passes; Thread eye 21 apertures are provided with the port lid 22 that makes thread eye 21 sealings, and the length of protecting pipe 3 is 10cm.
On the outer tube 2 that is positioned at protecting pipe 3 mouth of pipe places, offer and be used for the thread eye 21 that stiff guide wire passes; Bigger calculus is stuck in basket 1 when occurring; Calculus is reined in not broken when from basket 1, not discharging again, can make things convenient for the doctor in thread eye 21, to penetrate stiff guide wire, and stiff guide wire arrives calculus from outer tube 2; Through stiff guide wire calculus is smashed to pieces or calculus is transferred to from basket 1, thereby let the doctor continue to get stone.
With above-mentioned desirable embodiment according to this utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the description, must confirm its technical scope according to the claim scope.
