Description

A kind of medical dilating sacculus

Technical field

The present invention relates to medical apparatus and instruments technical field, more particularly to a kind of medical dilating sacculus.

Background technology

Interventional medical device is medical device technology emerging in recent years, and it is on the bed reduced to patient, raising disease Very important effect is played in terms of therapeutic effect.For example, apply in the various intraluminal insertion type balloon expandable devices of human body The narrow and small tube chamber support of human body can be reached into the purpose for the treatment of greatly as dilation support, but existing balloon expandable device Active section is the tubular body of even thickness, in the interventional therapy operation of long and narrow lesion, with the appearance of overlength support, conveying branch The length of balloon of frame is also continuously increased, and the diameter of tube chamber constantly diminishes, if using the sacculus of normal structure, near-end expands in operation Terminate to perform the operation when opening just, then distal end may have been subjected to powder and expand, and distal end tube chamber is damaged, and it is narrow again Post operation easily occur It is narrow；If distal dilation just when terminate to perform the operation, near-end may not expanded fully, support completely it is adherent, easily cause blood Bolt even occlusion, and when enter narrow and small tube chamber using existing sacculus, often balloon portion is difficult to support pipe Chamber, influence the progress of operation.

The content of the invention

To overcome disadvantages mentioned above, it is an object of the invention to provide a kind of medical dilating sacculus, existing sacculus can solve the problem that Can not release the deficiency of taper lumen stenotic lesion, at the same can support column tube chamber, ensure the quality of operation.

In order to reach object above, the technical solution adopted by the present invention is：A kind of medical dilating sacculus, including push pipe, Inner tube and distensible sacculus, the sacculus are arranged on the distal end of the push pipe, and said inner tube is arranged in the push pipe And running through the sacculus, the push pipe is in hollow structure, and the near-end of the push pipe is provided with connector, and the sacculus is remote to be pushed away The one end and said inner tube for sending pipe are welded, and the sacculus welds close to one end of push pipe with the push rod, and the sacculus exists Shape after inflation is tapered, rectangular laminated structure during the sacculus unaerated, and can fold, and easily enters lesion pipe Chamber.

Further, the first opening and the second opening are offered on the connector, seal wire penetrates from the described first opening Passed by the front end sky of said inner tube, while the second opening is passage, for being ventilated to the sacculus, makes balloon expandable, The gas ensured into sacculus will not be revealed, and the effect of balloon expandable is effectively ensured, and both are independent of each other, and cooperate.

Further, integrally formed Y-valve is provided between first opening, the second opening and connector, for strengthening The intensity of medical dilating sacculus.

Further, the push pipe is connected close to one end of the connector with said inner tube by connecting tube, described One end of connecting tube is welded with said inner tube, and the other end of the connecting tube is set on the push pipe, the connecting tube One end is arranged in the connector, and the other end is arranged in protection pipe, and the protection pipe is integrally formed with connector, the guarantor Pillar can effectively spread the pressure of balloon expandable inner tube, increase resistance to pressure.

Further, the port of first opening and the second opening is equipped with female Luer.

Further, the length of the sacculus is 5-100mm, a diameter of 1-20cm of the sacculus after expansion, after expansion The sacculus proximal part diameter it is bigger 0.5-5cm than the diameter of distal end.

Further, the sacculus is made of nylon.

A kind of medical dilating sacculus provided by the invention, sacculus are inflated by pushing pipe, and sacculus is supportted to expansion state, ball It is tapered after capsule expansion, support conveying is carried out, taper sacculus is capable of the lumen of support column lesion, anti-sliding stop/movement, can solved Certainly existing sacculus can not release the deficiency of taper lumen stenotic lesion；After the sacculus is evacuated, sacculus returns back to folded state, Effectively improve the simplicity of operation.
