Abstract
The utility model relates to a biliary stone extractor with a wire guiding slot. A net basket, an outer tube, a sheath tube, a front handle and a rear handle are sequentially arranged from the head to the tail of the biliary stone extractor; a soft pull rope which can slide freely and is connected with one end of the net basket is arranged in the outer tube; the other end of the soft pull rope is connected with a hard pull rope; one end of the hard pull rope is fixedly connected with the rear handle; a guide head is welded at the other end of the net basket; the surface of the guide head is provided with the wire guiding slot through which a zebra guide wire penetrates; and the width of the notch of the wire guiding slot is smaller than the diameter of the zebra guide wire. The zebra guide wire with a good lubricating effect in water is clamped in the stone extractor, and then the guide head, together with the zebra guide wire, slides to a position where a stone is required to be extracted, so the stone extractor is fast and convenient; and the wire guiding slot is obliquely formed on the lateral surface of the guide head, and the contact face between the zebra guide wire and the wire guiding slot can be increased, so that the stone extractor slides stably.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of biliary tract stone extraction device that has the seal wire groove.
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.
Traditional stone process of getting is the position that directly slowly arrives cholelithiasis with dislodger; Mainly refer to utilize the dislodger front target seeker be used for guide dislodger to arrive the place of working; But when intestinal is baroque in some bodies; This dislodger of the guiding of target seeker that only relies on will lose direction halfway, can't continue guiding and go down.
The utility model content
The technical problem that this utility model will solve is: overcome the deficiency of prior art, a kind of biliary tract stone extraction device that has the seal wire groove is provided, the target seeker that solves dislodger is guided inconvenience, is used incomplete defective.
This utility model solves the technical scheme that its technical problem adopted: a kind of biliary tract stone extraction device that has the seal wire groove; Be provided with basket, outer tube, protecting pipe, front hand grip and back handle by the end successively to afterbody; Be provided with the soft drawn rope that can be free to slide and be connected in the described outer tube with basket one end; The other end of said 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 the other end of described basket is welded with target seeker; Described target seeker surface offers and is used for the seal wire groove that the zebra seal wire passes, and the width of said seal wire groove notch is less than the diameter of zebra seal wire.
Furtherly, described seal wire groove is obliquely installed on the side surface of target seeker.
The beneficial effect of this utility model is: this utility model relates to a kind of biliary tract stone extraction device that has the seal wire groove; At first with the zebra seal wire through required place of getting stone; Then through on target seeker, offering a seal wire groove; With meeting zebra seal wire clip that glassware for drinking water has a good lubricant effect therein, then target seeker is just along with the zebra seal wire required place of getting stone of slipping together, and is efficient and convenient; The seal wire groove is obliquely installed on the side surface of target seeker, can increase the contact surface of zebra seal wire and seal wire groove, makes slip more stable.
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, front hand grip, 11, target seeker, 12, the seal wire groove.
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 biliary tract stone extraction device that have seal wire groove shown in Figure 2 like Fig. 1; Be provided with basket 1, outer tube 2, protecting pipe, front hand grip 3 and back handle by the end successively to afterbody; Be provided with the soft drawn rope that can be free to slide and be connected with basket 1 one ends in the outer tube 2, 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; The other end of basket 1 is welded with target seeker 11; Target seeker 11 surfaces offer and are used for the seal wire groove 12 that the zebra seal wire passes, and the width of seal wire groove 12 notches is less than the diameter of zebra seal wire, and seal wire groove 12 is obliquely installed on the side surface of target seeker 11.
At first the zebra seal wire is passed into the position of calculus in the biliary tract; Because lubricant effect is relatively good the zebra seal wire is met water in human body after; The zebra seal wire is passed the seal wire groove 12 on the target seeker 11; Then target seeker 11 just slowly slippage arrived the position at calculus place, just can begin patient is got 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.
