Abstract

The invention discloses a guide wire super-selective balloon catheter by which a guide direction can be regulated. According to the technical scheme, a main body of the balloon catheter is a tubular body; two balloons are fixedly arranged on the outer wall surface of the tubular body; the balloons are eccentric bag bodies which are non-axial with the central axis of the tubular body, and the two balloons are different in eccentric direction; and two filling cavities, which communicate with the two balloons, are additionally formed in the tubular body. Compared with the prior technologies, the balloon catheter disclosed by the invention has the beneficial effects that the direction of a guide wire can be effectively and rapidly regulated to the entrance of a designated pipeline, so as to facilitate entry of the guide wire; therefore, an operation time is shortened and a guide wire super-selective success rate is improved.

Description

The super ductus bursae of choosing shuttles of seal wire

Technical field

The present invention relates to field of surgical, particularly a kind of super ductus bursae of choosing shuttles of seal wire.

Background technology

Biliary tract is clinical common disease, and the treatment of conventional biliary tract biases toward surgical operation.In recent years, Along with diseases such as the development of endoscopic technic, a lot of calculus of bile duct, bile duct benign and malignant stenosis, can be through scope Retrograde cholangiopancreatography (ERCP) is treated.Endoscopic Treatment biliary tract mainly includes three aspects: 1. The taking-up of calculus of bile duct；2. release the obstructive jaundice caused by biliary tract or pancreas tumor；3, biliary benign is released Narrow biliary tract stenosis as caused by Medicinal Biliary Tract Injury etc..So-called endoscopic stone extraction technique is general by basket or gas Capsule takes stone.Releasing the obstructive jaundice caused by biliary tract or pancreas tumor under so-called scope is exactly seal wire choosing under scope Selecting property inserts stenosis of common bile duct section, and seal wire, by after narrow section, inserts biliary tract prosthesis drain under seal wire guides Bile releases and blocks.Releasing placement for benign biliary tract stricture is exactly seal wire by after narrow section, under seal wire guides with Dilatable bougie expands narrow bile duct step by step, it is possible to dilating sacculus expands narrow bile duct, thus it is narrow to release biliary tract Narrow.But there is the situation of selective catheterizaiton difficulty clinically, i.e. seal wire enters non-targeted tract, especially repeatedly It is that eccentric position is positioned at for narrow lacuna, or for hilar bile duct stricture, seal wire enters target cavity repeatedly A tract beyond road.Problems with can be produced the most undoubtedly: 1. operating time extends；2. reduce successfully Rate；3. increase the chance of postoperative infection.

Summary of the invention

It is an object of the invention to: the super ductus bursae of choosing shuttles of seal wire of channeling direction can be adjusted.

The present invention is achieved through the following technical solutions: its main body is a body, on the outer side surface of body Being installed with two sacculus, described sacculus is and body axis out-of-alignment bias utricule, and two sacculus Eccentric direction is different, body is additionally provided with 2 respectively with the full chamber of Liang Ge sacculus UNICOM.

Before relatively for technology, the invention have the benefit that and can efficiently and effectively the direction of seal wire be adjusted Whole arriving specifies entrance, facilitates seal wire to enter, decreases the time of operation, improves the super merit of hanking of seal wire Rate.

Label declaration: 1 body, 11 axis, 2 sacculus.

Detailed description of the invention

Illustrate below in conjunction with the accompanying drawings the present invention is elaborated:

As shown in Figure 1: its main body is body 1, the outer side surface of body is installed with two sacculus 2, Described sacculus is and body 1 axis 11 out-of-alignment bias utricule, and the eccentric direction of two sacculus is different, Body is additionally provided with 2 respectively with the full chamber of Liang Ge sacculus UNICOM.The structure in full chamber is existing routine Technology, therefore omit in the accompanying drawings.

Wherein, it is preferred on the contrary with the eccentric direction of two sacculus.Can be best judge the direction that conduit tilts.

In general, two sacculus are respectively positioned on body on the outer side surface of front end, two sacculus spacing 1cm to 2cm.

Body is four cavity configurations, fills chamber, guidewire lumen and injecting cavity including two sacculus.

Body arranges sacculus, and sacculus UNICOM fills chamber, is the technology of existing comparative maturity, such as, exists Carrying out when taking stone operation of calculus of bile duct, be used for taking stone takes stone foley's tube, manufacture view not spy Not difficult place, the application is with the distinctive points of prior art maximum, and have employed two sacculus, sacculus is equal Done eccentric design, and the main purpose of sacculus not be used for taking stone, and be used to guiding tube head end towards. Its operation principle is as follows:

As Figure 2-3: as a example by practical operation, in operation process, complete the main nipple of duodenum deep After intubating, when the head end of seal wire arrives narrow section bile duct or left and right common hepatic duct intersection, need seal wire side to the left Or side to the right enters Target pipe and generally has the composition of fortune, if the seal wire that makes repeated attempts fails to enter target tube Road, so time need to insert the tail end of seal wire from the guidewire lumen of the present invention, and insert through seal wire always until The body leading section of the present invention flushes with seal wire substantially.Afterwards, according to the direction of target tract, the need to Conduit head end inclined left side, second sacculus being pointed to body leading section is inflated, it is ensured that conduit is overall Offset to the left, now body together with seal wire closer to left side；If needing conduit head end inclined right side, need First sacculus being pointed to body leading section is inflated so that body first half offsets to the right.If mesh Mark pipeline is left common hepatic duct, can inflate two sacculus, this time simultaneously, arise that between two sacculus Body (porch of Target pipe) to the right there occurs inclination (bending), and the front end of body is the most straight Connect the porch towards Target pipe, so that seal wire can enter left common hepatic duct smoothly.

Focusing on here: 2 sacculus can allow body generation curving, and if only one of which sacculus, Body only can overall offset, and the front end of body is the most also directed towards front, rather than to the left or to the right.

Additionally it is also devised with radiopaque Marking ring structure, with the position of clear and definite foley's tube.

Although the present invention uses specific embodiment and alternative thereof illustrate the present invention and illustrate, but should Work as understanding, all can implement without departing from the variations and modifications in the scope of the present invention.Therefore, Being to be understood that in addition to being limited by appended claims and condition of equivalent thereof, the present invention is not by all senses On restriction.
