Background technology
The patient of common Great Vascular Injury in clinical position, iatrogenic injury, large artery trunks false aneurysm etc. in enclosed mass art.In operation, often run into the problems such as injured blood vessel exposes and anthemorrhagic difficulty, and intraoperative hemorrhage is more, even therefore seriously jeopardize patient's life.In treatment, generally need the nearly section far away of free damage tremulous pulse, blocking-up could be repaired operations such as sewing up blood vessel after controlling, especially rely on patient's operation skill and operant level in inferior process.Can use in some cases the near-end of the auxiliary blocking-up damage of single saccule conduit (comprise sacculus get bolt conduit, sacculus dilating catheter etc.) tremulous pulse to be beneficial to operation, but these catheter-balloons can not meet completely stop blooding needs or use cost higher.In addition, using these single saccule conduits to carry out intracavity when blocking-up can only interruption artery near-end blood flow, can not meet operation needs completely cutting while processing arteria iliacofemoralis section false aneurysm, and existing also have related invention to create appearance.
CN 203090200 U as open in Chinese patent, a kind of novel dual balloon catheter is disclosed, comprise hollow conduit body, sacculus I and sacculus II, the inwall of described hollow conduit body is provided with two passages that are respectively used to inject to sacculus I and sacculus II the medium that makes its expansion, on the hollow conduit body between described sacculus I and sacculus II, is provided with opening B.
Foregoing invention adopts its complex operation of two-chamber control sacculus order air inlet, and sacculus is shaped as that spherical contact less barrier effect with blood vessel poor, and seam, without its maintenance weak effect of blocked valve, is applied in unfavorable Rhizoma Atractylodis Macrocephalae.
Utility model content
Adopt two-chamber control ball valve its complex operation of air inlet (liquid) respectively in order to solve existing pair of sacculus blood vessel blocking conduit, sacculus is shaped as that spherical contact less barrier effect with blood vessel poor, without blocked valve, it keeps the shortcoming of weak effect to seam, and this utility model provides a kind of two sacculus blood vessel blocking conduit.
This utility model solves the technical scheme that its technical problem adopts: the two sacculus blood vessel blocking conduits of described one, comprise resilient bladder, conduit, polymeric block, blocked valve, described conduit is provided with guidewire lumen and liquid guiding cavity, guidewire lumen is communicated with catheter tip surface, catheter tip is connected with polymeric block, conduit is bifurcated in polymeric block, guidewire lumen with enter fiber tube and be communicated with, liquid guiding cavity is communicated with feed tube, the first resilient bladder has been linked in sequence on conduit, the second resilient bladder, the first resilient bladder is near catheter tip, conduit between the second sacculus and polymeric block is provided with the pod apertures of connecting tube surface and guidewire lumen, it is characterized in that, the described feed liquor mouth of pipe is provided with blocked valve, liquid guiding cavity is communicated with the first sacculus by the first side opening, liquid guiding cavity is communicated with the second sacculus by the second side opening, the first side opening aperture is different from the second side opening aperture, described pod apertures is inclined on conduit, pod apertures is in the opening deflection polymeric block direction of catheter surface, pod apertures is in the opening deflection catheter tip of guidewire lumen.
Further, described the first sacculus and the second sacculus are cylindric, and length of balloon is 2: 1 or 3: 2 with full rear maximum gauge ratio.
Further, described the first sacculus and the second balloon surface are provided with annular projection.
Further, described liquid guiding cavity is arranged in conduit one side.
Further, the liquid guiding cavity of described catheter section is crescent shape.
Further, described the first side opening aperture and the second side opening aperture ratio are 1: 2 or 2: 1.
The beneficial effects of the utility model are: adopt two-chamber sequential control to avoid hypertonia between sacculus to cause barrier effect poor, also reduce operating procedure and avoid multi-cavity air inlet (liquid) simultaneously, it is better that balloon surface annular projection avoids blood to be accumulated between sacculus and blood vessel barrier effect, and feed tube is provided with blocked valve and can effectively keeps balloon pressure simple to operate.
