Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of intravascular calcified plaque or calcification ring ultrasonic grinding dress
It sets.
Background technique
Percutaneous transluminal coronary angioplasty (PTCA) is coronary atherosclerotic heart disease (coronary heart disease) blood vessel again
The critical treatment method of change, but it is located at stem portion, opening portion, bifurcated as narrow to the coronary artery anatomy damage of complicated form
The treatment success for the lesions such as portion, total occlusion, longer side tubular, calcification or hard fibre, sacculus cannot be expanded, and caliber is narrow
Rate is low, and operation difficulty is big, complication is more, big using difficulty especially in the patient of Type B and c-type coronary artery pathological changes.
Turnery art (PTCRA) is using compressed air as power in percutaneous coronary, and driving surface is embedded with diamond crystals
Bistrique high speed rotation, after conduit is sent into coronary artery chamber, alternative grinds off hard, calcification atheromatous plaque in vascular wall,
Smooth lumen of vessels to be rebuild, narrow coronary flow imaging is made, PTCRA clinic is mainly used for the patient of PTCA art application difficult,
As inner membrance hard fibre, patch calcification, arterial wall itself have diverticulum sample recess to change；At vascular bending position, bifurcation, open
Oral area position and LM stenosis；Tubulose and it is dispersed in segmental stricture etc..Especially c-type is damaged, and the application effect of PTCRA is preferable.
In addition, narrow, the PTCA postoperative restenosis of expanding plasty failure can also be treated with PTCRA to the coronary artery of recent fully closed plug.
The shortcomings that 3.2 prior art
PTCRA operation in easily occur coronary blood flow be obstructed, blood vessel acute embolic, arrhythmia cordis, endangium tearing or wear
Hole etc. is unexpected.The postoperative generally existing site of puncture bleeding of PTCRA, subcutaneous hematoma, acute and subacute stent thrombosis, low blood pressure, defecation
The adverse reactions such as difficulty, pain, shock.
Because of the limitation of hard calcification ring, common non-compliance sacculus is often difficult to effectively pre- coronary calcification lesion
Expand, is difficult to success high pressure resistant sacculus.Coronary calcification increases sacculus rupture, coronary artery tearing, perforates and without multiple
The operation risks such as stream.It causes stent expansion bad, bad expanding effect afterwards, " dog bone " expansion effect often occurs.
Therefore, severe calcification lesion is adequately pre-processed particularly significant.The PCI guide of U.S. AHA in 2011, by severe calcification and
Fibrosis lesion turnery art recommends evidence as II a class.Pretreatment of the Cutting balloon as height calcification lesion can get good
Effect.But turnery art or Cutting balloon angioplasty is used alone, the calcification ring of many thickness can not be made to be broken.
Turnery art is the conduit of the turnery head using head end with miniature diamond grains, is ground with the high speed of 15~18r/min
The ingredient of hard in patch is ground, it is small to soft vessel wall damage.But at present clinically workable turnery area of bed be 1.25~
The full-size of 2.75mm, Discussion on Chinese Listed are 1.75mm, and it is insufficient to have turnery for biggish lumen.When turnery head selects
Excessive, size and when vessel diameter ratio > 0.8, acute vascular complications obviously increase.Therefore, for thicker superficial calcification
The effect of ring, turnery mainly polishes to the hard calcified tubercle on its surface, calcification ring can not be thoroughly rubbed, to soft spot
Block does not also act on.
Summary of the invention
In conclusion in order to overcome the deficiencies of the prior art, technical problem to be solved by the invention is to provide a kind of blood vessels
Interior calcified plaque or calcification ring ultrasonic grinding device.
The technical scheme to solve the above technical problems is that a kind of intravascular calcified plaque or calcification ring ultrasonic wave are ground
Mill apparatus, including supersonic generator, guiding catheter, grinding conduit, grinding seal wire and grinding rod；The guiding catheter is inserted in
The inside of patient's femoral artery sheath, the grinding conduit are in the inside of the guiding catheter, and the grinding rod passes through described grind
The position at angiosteosis spot or calcification ring is reached after mill conduit；
It is external that one end of the grinding seal wire be in patient, and the other end passes through energy converter company after passing through the grinding conduit
Connect the grinding rod；The delivery outlet of the supersonic generator connects the grinding seal wire and is in the external end of patient and sending
Ultrasonic wave makes calcified plaque or calcification ring in the grinding rod vibro-grinding narrow blood vessel.
The beneficial effects of the present invention are: the apparatus structure is simple, performance is stable, convenient for operation.Can have using the present invention
Effect reduces postoperative complication, eliminates traditional turnery device and generates influence of the deviation to processing in turnery, improves grinding efficiency.
Based on the above technical solution, the present invention can also be improved as follows:
Further, corresponding to be equipped at the external position of patient on the grinding seal wire drives the grinding rod along described
The propeller that seal wire is moved forward and backward, corresponds to be additionally provided at the external position of patient and grind in the grinding rod on the grinding seal wire
The brake of the position of the fixed grinding seal wire during mill.
Wherein, above-mentioned propeller and the equal Xiang Boke International Medical trade (Shanghai) Co., Ltd. of brake are commercially available, and two
Person's existing product.
The beneficial effects of adopting the above-mentioned further technical scheme are as follows: it is realized by propeller and grinding rod is pushed into narrow disease
The proximal end of change is fixed positioning when stick to be ground is pushed to desired position by brake.
Further, the forward outer surface of the grinding rod is uniformly embedded with several diamond grains for grinding.
The beneficial effects of adopting the above-mentioned further technical scheme are as follows: intravascular grinding art is used grinds with small diamond grains
Frotton, selectively dispels the arteriosclerosis plaque of fibrosis or calcification according to " difference grinding " principle, and flexible blood
Tubing vibration at high speed grinding rod by when can nature flick, i.e., grinding rod does not grind flexible tissue and normal blood vessels
Wall.
Further, the side wall of the grinding conduit is equipped with to the fill orifice that medication in art is perfused inside it.
It further, further include foot-operated control panel；The foot-operated control panel connects the power switch of the supersonic generator
And the opening and closing of the supersonic generator are controlled by foot-operated triggering.
Beneficial effect using above-mentioned further scheme is: the opening and closing of supersonic generator is controlled, to control grinding
The vibro-grinding of stick and stopping are ground.
Further, the front of the supersonic generator is equipped with the display screen of the frequency for the ultrasonic wave that display currently occurs,
The regulating key for adjusting the frequency of the ultrasonic wave occurred is additionally provided in the front of the supersonic generator.
Beneficial effect using above-mentioned further scheme is: grasping current preceding supersonic generator according to the actual situation and occurs
Ultrasonic wave frequency, and the frequency of the ultrasonic wave occurred in due course by regulating key.
