Abstract
The utility model relates to vascular intervention equipment, in particular to a sacculus expanding canal. The sacculus expanding canal comprises an external canal, an internal canal and a guide screw, wherein at least two sections of sacculus bodies which are coaxial with the guide screw are arranged on the external canal; and the two ends of the sacculus bodies have ladder-shaped structures. A plurality of sacculus bodies are arranged to expand a plurality of narrow parts of the same blood vessel at the same time, so that the discomfort of a patient caused by repeated canal insertion is avoided; and the two ends of the sacculus bodies have the ladder-shaped structures to expand the same section of the blood vessel at the same time, so that the damage to the blood vessel caused by the overexpansion of the two ends is avoided and the risk of a failed surgery is effectively reduced.
Description
Technical field
This utility model relates to a kind of blood vessel and gets involved equipment, relates in particular to a kind of sacculus dilating catheter.
Background technology
Get involved in the blood vessel or the medical skill that treatment technology is the internal medicine method lieu of surgery used always is hindered by Wicresoft.Often will use sacculus dilating catheter in vascular interventional treatment, existing sacculus dilating catheter only is provided with a sacculus body, once can only expand one section narrow blood vessel during use.In case when the patient's blood vessel narrow location was between a few sections adjacent regions of same blood vessel, the sacculus dilating catheter that generally uses can't once be finished dilation therapy now, must the gradation expansion, bring more misery to patient.In addition, existing sacculus body mostly is the spindle of neutral straight, two end topers greatly, and this structure in use, normally two ends expansion is earlier opened, and certain depression appears in the centre, opens for expanding in the middle of making, need continue as sacculus body inflation, cause blood vessel injury because of the two ends overdistension easily like this.
Summary of the invention
At the problems referred to above, this utility model provides that a kind of energy is disposable to be expanded the multistage narrow blood vessel, and can avoid the sacculus dilating catheter of the blood vessel injury that overdistension causes.
Sacculus dilating catheter described in the utility model comprises outer catheter, inner catheter and seal wire, and described outer catheter is provided with at least two sections and the co-axial sacculus body of seal wire, and described sacculus body two ends are the notch cuttype structure.
For helping foley's tube fast moving in blood vessel, the outer surface of described sacculus body and outer catheter is provided with hydrophilic coating.
Accurately navigate to the narrow blood vessel place for ease of the sacculus body, be provided with the ring that develops with sacculus body correspondence position on the described inner catheter.
Further, the notch cuttype structure of described sacculus body is made of a plurality of flat section and awl sections.
Further, described flat section is circular arc with the intersegmental changeover portion that is connected of awl.Arc-shaped structure can guarantee the flatness of conduit, has improved the ride-through capability of conduit.
This utility model is provided with multistage sacculus body, can strut the many places narrow blood vessel of same blood vessel simultaneously, avoid bringing sense of discomfort to patient because of repeatedly inserting conduit, in addition, sacculus body two ends are set to stepped, can expand dress synchronously to same section blood vessel, prevent that the two ends overdistension from causing blood vessel injury, effectively reduces the risk of operative failure.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram of sacculus body;
Among the figure, 1, outer catheter, 2, the sacculus body, 3, the ring that develops, 4, inner catheter, 5, seal wire, 6, connect changeover portion, 7, flat section, 8, the awl section.
The specific embodiment
A kind of sacculus dilating catheter as shown in the figure, comprises outer catheter 1, inner catheter 4 and seal wire 5, and described outer catheter 1 is provided with at least two sections and seal wire 5 co-axial sacculus bodies 2.Be provided with the ring 3 that develops with sacculus body 2 correspondence positions on the described inner catheter 4, the length of the ring 3 that develops is identical with the length of sacculus body 2.Each sacculus body 2 all is by 7 and three sections awl sections of four sections flat sections, 8 notch cuttype structures that constitute, and what flat section 7 and 8 of awl sections were provided with circular arc is connected changeover portion 6.The outer surface of sacculus body 2 and outer catheter 1 is covered with hydrophilic coating.
During use, can select the sacculus dilating catheter of corresponding hop count and corresponding spacing according to the operation needs, with the conduit percutaneous intravasation that shrinks in advance, under the guiding of medical imaging device, make the sacculus body arrive the narrow blood vessel position by the ring that develops, inflation or topping up body make the sacculus body expand piecemeal, thereby strut the narrow blood vessel in many places.
