when the blood vessel plug scraping device is used, the supporting frame (9) bears the inner side wall of a blood vessel of a patient, the piezoelectric ceramic wafer (2) drives the sealing sleeve (1) to vibrate axially, the sliding block (10) slides in the sliding groove (16), the sliding block (10) drives the driving gear (12-1) to reciprocate, the driving gear (12-1) and the sealing sleeve (1) generate reciprocating displacement, the two are connected through the connecting rod (12-2), the driving gear (12-1) is driven to rotate through the connecting rod (12-2), the driving gear (12-1) drives the end face gear (12-3) to rotate, the fixing sleeve rotates, the scraping plate (11) is driven to rotate around the outer side of the sealing sleeve (1), and plug adhesion objects in the blood vessel are scraped.
5. The built-in ultrasonic transducer for reducing blood pressure and blood vessel thrombosis according to claim 1, wherein the sliding groove (16) is internally and fixedly provided with the elastic air bag (14), the elastic air bag (14) is arranged at one side of the sliding block (10) far away from the scraper (11), when the sliding block (10) is in a static state, the elastic air bags (14) at two sides respectively prop against the sliding blocks (10) at two sides, and further when the sliding block (10) starts to slide in the sliding groove (16), the elastic air bags (14) are always kept to prop against the sliding block (10), so that the elastic air bags (14) give the initial inertial kinetic energy of the reciprocating motion to the sliding block (10).
6. The built-in ultrasonic transducer for reducing blood pressure and blood vessel thrombus as claimed in claim 1, wherein the side of the scraper (11) perpendicular to the outer side wall of the sealing sleeve (1) is edged.
7. The working principle of the built-in ultrasonic transducer for reducing blood pressure and blood vessel thrombosis as claimed in claim 1 is as follows: during use, the inflating hose (7) is clamped on the connecting seat (5) through the clamping piece, then the sealing sleeve (1) is placed into a embolism blood vessel of a patient, then the piezoelectric ceramic wafer (2) is electrified through the electrode wire (3) to vibrate, and then the piezoelectric ceramic wafer (2) drives the sealing sleeve (1) to vibrate, so that the embolism blood vessel of the patient is dredged; when the sealing sleeve (1) is placed, the air pump (8) is used for inflating the inflatable hose (7), so that the inflatable hose (7) is expanded and tightened, the inflatable hose (7) serves as a support, the sealing sleeve (1) is plugged into a embolism blood vessel of a patient, and meanwhile, the expanded inflatable hose (7) serves as a support, and the specific position of the sealing sleeve (1) is adjusted; when putting patient's embolism blood vessel in during operation in big envelope (1), seal cover (1) is connected through between fixing base (4) and connecting seat (5), and when seal cover (1) takes place rotatoryly, rotate through the axle of being connected between fixing base (4) and connecting seat (5) and fall when putting seal cover (1) in patient's embolism blood vessel, support frame (9) bear on patient's the blood vessel inside wall, drive seal cover (1) vibration along with piezoceramics wafer (2), take place vibration displacement between its seal cover (1) and support frame (9), and then it is rotatory to drive solid fixed ring (17) through driving piece (12), and then solid fixed ring (17) drive scraper blade (11) rotate around the outside of seal cover (1), and then strike off the coagulum on the blood vessel inside wall of embolism through scraper blade (11).
