Operating platform for percutaneous coronary artery stent implantation

Abstract

The invention relates to an operating platform for percutaneous coronary artery stent implantation, which consists of a tainted blood tank, a cotton gauze tank, a sundries tank, a near-end thread-guiding clip, a far-end thread-guiding clip, a trapezoidal opening and a tainted blood tank cover plate.

Description

technical field [0001] The invention relates to a medical device, in particular to an operating platform for surgery. technical background [0002] With the aging of the global population, PCI (percutaneous coronary stent implantation) operations are increasing year by year, and now there are about 2 million PCI operations worldwide. [0003] In PCI surgery, when exchanging balloons or stents, although the doctor concentrates on grasping the guide wire, almost every time the balloon or stent is exchanged, the guide wire may be moved outward, allowing the guide wire to exit from the coronary artery. In severe stenosis or coronary artery dissection, it may be impossible to re-enter the coronary artery due to the prolapse of the guide wire or aggravate the coronary artery dissection, resulting in surgical failure. The inward movement of the guide wire may lead to coronary perforation. In mild cases, the operation will be terminated, and in severe cases, cardiac tamponade will ...

Problems solved by technology

[0003] In PCI surgery, when exchanging balloons or stents, although the doctor concentrates on grasping the guide wire, almost every time the balloon or stent is exchanged, the guide wire may be moved outward, allowing the guide wire to exit from the coronary artery. In case of severe stenosis or coronary artery dissection, it may be impossible to re-enter the coronary artery due to the prolapse of the guide wire or aggravate the coronary artery dissection, resulting in surgical failure

The inward movement of the guide wire may lead to coronary perforation. In mild cases, the operation will be terminated, and in severe cases, cardiac tamponade will be life-threatening. The incidence of coronary perforation caused by the guide wire in PCI surgery is about 0.5%. After the superhard guide wire passes through the lesion, the soft guide wire is often replaced to prevent coronary perforation. When more than two guide wires are used in PCI surgery, there is often confusion because the tail of the guide wire is not marked. Which blood vessel needs re-fluoroscopy to be clear, increasing the dose of radiation for doctors and patients. During PCI surgery, the operator and assistants need to fix the guide wire. At least 2 people are needed to complete the operation, and the items on the operating table are messy and there is no collection of dirty blood. During the operation, dirty blood overflowed and often splashed on the operator, and also polluted the operator's gloves, Y-shaped connectors, three-way three-way, ring handle syringes, etc., resulting in difficult operation and even mistakes. It is necessary to constantly wipe gloves and Y-shaped connectors, three-way three-way and ring handle syringes, which brings inconvenience to the operation process
