Abstract
The utility model relates to a medical pulmonary artery constrictive rack which decreases pulmonary artery pressure, avoids unnecessary pulmonary artery ring thoracotomy, reduces operation risk, prevents influence on later operation and has convenient use and high reliability. The utility model is a hollow funnel-like rack with framework made of memory alloy material, comprising a cylinder part and a funnel part. The cylinder part is covered with film outside, wherein the external surface of the film has barb structure with tip toward exit, so as to increase the resistance with pulmonary artery intima and prevent rack from sliding off. The inner of the funnel part is coated with film to block blood.
Description
One, technical field:
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of medical coarctation of pulmonary artery support.
Two, background technology:
At present, some heart disease need be gone pulmonic ring and be contracted art to reduce pulmonary artery pressure, and for post-operative is prepared, this operation needs to open under the general anesthesia breast to be carried out, and surgical injury is big, and tissue adhesion brings inconvenience to post-operative.Still do not have both at home and abroad at present a kind ofly can reduce pulmonary artery pressure, avoid carrying out the contract apparatus of art of unnecessary pulmonic ring.
Three, utility model content:
This utility model is in order to solve the weak point in the above-mentioned background technology, a kind of medical coarctation of pulmonary artery support is provided, it can reduce pulmonary artery pressure, avoid carrying out the unnecessary breast pulmonic ring art of drawing back one's hand of opening, thereby minimizing operation risk, avoided influence that post-operative is caused, and easy to use, the reliability height.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of medical coarctation of pulmonary artery support, its special character is: described support is the funnel-form support of hollow, and can freely stretch.
The skeleton of above-mentioned support adopts memory alloy material to make.
Above-mentioned funnel-form support comprises cylindrical portion and infundibulum, and wherein the porch is a cylindrical portion, and the exit is an infundibulum.
The outside overlay film of above-mentioned cylindrical portion.
The inner overlay film of above-mentioned infundibulum.
The outer surface of the outside overlay film of above-mentioned cylindrical portion has the reversed acanthoid structure, and is most advanced and sophisticated towards Way out.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
This utility model can reduce PBF, reduces pulmonary artery pressure, can avoid unnecessary open chest surgery, thereby reduces operation risk, has avoided influence that post-operative is caused, and easy to use, the reliability height.
Four, description of drawings:
Fig. 1 is the structural representation of this utility model deployed condition;
Fig. 2 is the internal structure sketch map of this utility model deployed condition;
Fig. 3 is the structural representation of this utility model contraction state.
Five, the specific embodiment:
Referring to Fig. 1, Fig. 2, this utility model is the funnel-form support of hollow, adopts memory alloy material to do skeleton, comprises cylindrical portion 1 and infundibulum 2, and 3 places that wherein enter the mouth are cylindrical portion, and exporting 4 places is infundibulum.Cylindrical portion 1 outside overlay film, the outer surface of film has the reversed acanthoid structure, and is most advanced and sophisticated towards outlet 4 directions, with intermembranous resistance in increase and the pulmonary artery, prevents the support slippage.Infundibulum 2 inner overlay films are to stop blood flow.Referring to Fig. 3, Figure 3 shows that the structural representation of support contraction state.Memorial alloy refresh memory in the time of 37 ℃ is deployed condition.In addition, stent size can have different model according to patient's pulmonary artery size.
During real work, when support is laid support casing is placed on outside the conduit, the support overcoat is with trocar sheath, conduit is inserted pulmonary artery through femoral vein or other large vein, determine that through radiography the position retreats except that trocar sheath, support is launched under body temperature, be close to and be fixed in the pulmonary artery.Also can assist stent open by support inner catheter air bag expansion.Pull out conduit.Like this, PBF must flow out through 2 outlets of narrow infundibulum, reaches the minimizing PBF, reduces the purpose of pulmonary artery pressure.
Claims (6)
1, a kind of medical coarctation of pulmonary artery support, it is characterized in that: described support is the funnel-form support of hollow, and can freely stretch.
2, medical coarctation of pulmonary artery support according to claim 1 is characterized in that: the skeleton of described support adopts memory alloy material to make.
3, medical coarctation of pulmonary artery support according to claim 2 is characterized in that: described funnel-form support comprises cylindrical portion (1) and infundibulum (2), and wherein inlet (3) locates to be cylindrical portion (1), and outlet (4) locates to be infundibulum (2).
