Abstract
The utility model provides a rotary cut guiding tube in blood vessel cavity, which belongs to the technical field of medical appliance devices, the structure of the guiding tube is characterized in that one end of a guiding tube is connected on one interface of an operational four-way tube, the other end of the guiding tube is provided with a sampling storage, the sampling storage is a hollow tubular structure, one side of the sampling storage is opened with a gap, a rotary cutter is arranged in the sampling storage, the rotary cutter is connected with a driving rod, an air sac is arranged on the sampling storage, the top end of the sampling storage is provided with a guiding steel wire, a driving guiding wire is arranged in the guiding tube, one end of the driving guiding wire is connected with the driving rod, the other end is traversed outside the operational four-way tube and is connected with a rotating device in a motor, a blade pushing rod is arranged on the rotating device, and the other two interfaces of the four-way tube are respectively connected with a washing tube and an air sack charging port. The rotary cut guiding tube can allow the guiding tube to smoothly pass and reach the diseased portion, which reduces the perforation danger, and the guiding tube is suitable for coronary artery and peripheral blood vessel atheromatous plaque removal.
Description
Technical field
This utility model relates to technical field of medical instruments, atherectomy catheter in specifically a kind of lumen of vessels.
Background technology
General, the interventional therapy technology is used for the treatment of cardiovascular disease and uses very extensive in modernized clinical treatment.Laser angioplasty is also very general in practice and application clinically, this art is to utilize optical fibers laser can be transmitted the diseased region of a blood vessel, by thermal degradation or the photochemical reaction of laser to target tissue and gruel type speckle, rapid vaporization target material, to obtain revascularization, this art is applied to coronary artery and peripheral blood vessel can solve a lot of clinical insoluble problems.But there are some serious and be difficult to overcome problems in it: when executing art, damage the contiguous tissue of vaporization speckle easily, and its transmission system instability, vaporization calcified plaque DeGrain also causes vascular puncture easily, and other severe complications can occur.This is in clinical safety operation is used, and some complicated state of an illness has directly limited the application and the effect of above-mentioned art, at this moment has to and begins the in addition R and D of the mechanical means of the angioplasty of classics in medical circle.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and atherectomy catheter in a kind of lumen of vessels is provided.
The technical solution of the utility model realizes in the following manner, atherectomy catheter in this lumen of vessels, its structure is that conduit one end is connected on the interface of operation four-way pipe, the conduit other end is provided with the sampling memorizer, the sampling memorizer is a hollow tubular structures, sampling memorizer one side offers breach, be provided with the rotary-cut cutter in the sampling memorizer, the rotary-cut cutter is connected with drive rod, a side relative with breach is provided with air bag on the sampling memorizer, the top of sampling memorizer is provided with the guiding steel wire, be provided with the driving seal wire in the conduit, drive seal wire one end and be connected with drive rod, the other end passes the interface relative with catheter interface of operating four-way pipe and is connected with rot in being arranged on motor, rot is provided with the blade catch bar, and two interfaces in addition of operation four-way pipe connect syringe pipe and air bag inflation inlet respectively.
Syringe pipe is provided with the flushing liquor valve.
Be connected with the minimum gas syringe on the airbag aeration mouth.
The beneficial effect that this utility model is compared with prior art produced is:
In this lumen of vessels the setting of the guiding steel wire of atherectomy catheter with guarantee conduit smoothly by and arrive at diseased region, keep conduit coaxial with blood vessel, it is dangerous to reduce perforation, can be used for the excision of coronary artery and peripheral blood vessel atherosclerotic plaque, to highly narrow, entirely shut, that calcification, off-centre, pathological changes are long etc. is all applicable.
