Abstract

The utility model relates to an endoscope multi-ring continuous ligator. The utility model is composed of a ligation tube, ligation rings, a single pull line and a pulling turn knob. The utility model is directly arranged at the front end of an endoscope, and is led into an esophagus by the endoscope. The circular and elastic ligation ring with a small nodule is changed to be in a spiral shape after expanding and processing. After the ligation ring is assembled on the ligation tube, the ligation ring can easily roll forward along the slope power of the outer side of the front half part of the ligation tube and can quickly slide when the ligation ring is pulled, and then, the ligation ring elastically retracts to be ligated at the root part of the varicose vein to finish the one-time ligation process. As the pulling turn knob rotates for a circle, one ligation ring is controlled to fall off. The endoscope multi-ring continuous ligator is operated visually, conveniently and quickly under the direct vision of the endoscope, so a patient feels a little pain and the work efficiency is improved. The utility model has the advantages of simple structure, and easy processing and production.

Description

The multi-ring continuous ligature carrier of scope

A kind of multi-ring continuous ligature carrier of scope that uses at direct view under endoscope belongs to medical apparatus and instruments.

Use imported product (as the speedbnnd five rings ligature carrier of boston, u.s.a Science and Technology Ltd. development) that esophageal variceal vein is carried out the direct view under endoscope ligation treatment, product structure is complicated, and draught line is more, and price is higher.Use home products (as the product of sky, Tianjin doctor's medical grade silicon rubber products factory development) to need to insert a thicker trocar sheath, patient is painful big, easily cause the injury of throat and epimere esophagus, simultaneously scope is wanted repeated multiple times to pass in and out esophagus and just can be finished ligation to several cirso-s, ligation continuously, so operation is more numerous and diverse, efficient is lower.

In view of the foregoing, the purpose of this invention is to provide a kind of intuitively easy in direct view under endoscope operation, the efficient height, simple in structure, be easy to processing, cheap, the multi-ring continuous ligature carrier of operation principle novelty.

The multi-ring continuous ligature carrier of scope is made of ligation pipe, ligation ring, draught line, traction knob.

The multi-ring continuous ligature carrier of scope directly is placed in the front end of scope, imports esophagus by scope, and is intuitively easy in the direct view under endoscope operation, can once finish the ligation to many esophageal variceal veins, and patient's misery is little, the efficient height.The ligation pipe first half outside is slope shape, can hold a plurality of ligation rings simultaneously, and be beneficial to the ligation ring when being subjected to drawing to ligation pipe nose motion.Ligation pipe latter half medial surface attaches an elastic rubber tube, so that ligation pipe and the reliable socket of scope front end are fixed.The ligation ring is the garden annular, and its transverse section is square or garden shape, and there is half a garden shape lesser tubercle to outer process the part.When this kind elasticity ligation ring is expanded from small to large via the taper dilator, owing to be subjected to the nodular inhibition of half garden shape, the ligation ring is not whole rolling or slip, but the flexible rubber ring that is in shape lesser tubercle both sides, half garden rolls forward separately, when being expanded to needed size, when being installed on ligation pipe first half lateral surface, the cushion rubber of ligation ring is the symmetry helical form and changes, thereby obtain the reverse elasticity rolling power opposite with installation direction, when the traction that is subjected to ligation pipe front end, ligation this moment circumpolar easily rolls forward along the slope gesture in the ligation pipe first half outside, and slippage rapidly, finishes the ligation process one time.Single draught line leading portion sequential scheduling is apart from the lesser tubercle or the garden pearl of arranging several (5-10) fixed-site, lesser tubercle or garden pearl are placed in the nearside of the ligation ring that has been assemblied on the ligation pipe successively, all the other line segments pass between the ligation ring inboard and the ligation pipe outside, again via ligation pipe front end, draw after by forward direction from its inboard.Single draught line back segment is drawn via the biopsy channel of scope, bolt lies on the central shaft of traction knob, when clockwise direction rotary knob forward, draught line just is wound on the central shaft, first lesser tubercle or the garden pearl of tractive draught line leading portion nearside, driving corresponding first ligation hoop ligation pipe front end rolls, in like manner, when continuous rotary knob tractive draught line, the lesser tubercle of its leading portion ordered arrangement or garden pearl drive corresponding ligation hoop ligation pipe front end successively and roll, and along the slope gesture in succession rapidly from the ligation pipe successively skid come off, the elastical retraction ligation is finished successive ligation action in the cirso-root that is mound, garden shape protuberance of being gone into ligation pipe first half inboard by vacuum suction.Knob whenever is rotated a week, and ligation ring of may command comes off, and can successively finish multiple spot (5-10) the ligation treatment action to many esophageal variceal veins successively.

Product according to above-mentioned principle manufacturing is compared with existing external multi-ring continuous ligature carrier, one owing to adopted novel tuberculous helical form ligation ring, thereby make the ligation ring on the ligation pipe, produce rolling effect forward, the simple slip effect of complete product different from the past, be easier to coming off of ligation ring, operation is more easily simple; Two owing to only use single draught line just can affect a plurality of ligation rings continuously, so structure is simpler, reduced the interference to the scope visual field; It is littler that three categories of etiologic factors list draught line takies the space of biopsy channel of scope, thus can farthest bring into play the biopsy channel function of scope, as vacuum suction, flushing etc.

Most preferred embodiment of the present invention is, several have a garden annular ligation ring (3) to half garden shape lesser tubercle (4) of outer process, and after divergence process, its cushion rubber presents spiral-shaped change, is assemblied on the ligation pipe (1).The ligation pipe first half outside is ramped shaped, and the latter half medial surface attaches an elastic rubber tube (2).Single draught line (5) leading portion sequential scheduling is apart from the little line joint or the garden pearl (6) of arranging several fixed-site, and respectively corresponding with it ligation ring contact cooperates, and its back segment is connected with the central shaft of traction knob (7).

The ligation pipe is processed by nontoxic hard transparent plastic, and ligation ring and elastic rubber tube are by the rubber manufacturing, and draught line is by nylon or the processing of powerful silk thread, and the traction knob is made of plastics.
