Specific embodiment
As shown in Fig. 1, a kind of novel aspirate thrombi conduit, including support 12, support 12 be Y type female Luer, one
End is pump orifice 10, and one end is injection port 11, and the other end is working hole 9；9 external connection of working hole is used to push the outer tube of conduit
7, injection port 11 connects the inner tube 4 for injecting drug, and pump orifice 10 connects the supervisor 5 for extracting thrombus out；The supervisor 5 is passed through
It wears inside outer tube 7, inner tube 4 is inside supervisor 5；Described 5 one end apart from remote branch of a clan seat 12 of being responsible for is equipped with concave suction ball 3,
It is responsible for 5 perimeter surfaces and is equipped with support ball 6, support hollow in ball 6 and connect with inner tube 4, supervisor 5 and band are extended in 4 working end of inner tube
There is the injection block 2 of injection orifice 21 to connect, injection block 2 is metal block；3 inner surface of suction ball is equipped with several equally distributed pumpings
Sucker 31；2 front end of injection block is equipped with guide line 1.
The course of work of the invention is as follows:
Doctor, by the way that at human vas one, under blood vessel display 16, injection block 2 is metal block, can clearly be reflected with conduit
Image and location information are sent to controller 14 by catheter position, blood vessel display 16, and controller 14 controls intelligent machine arm 15,
Follow conduit mobile, outer tube 7 arrives at vascular lesion (thrombi) under the guide of guide line 1, and outer tube 7 is extracted out, and injection block 2 is stretched
Out, ultrasonic wave is opened, injection block 2 starts microseismic activity, and under negative pressure, suction ball 3 will not deform, and keep original shape, aspirates ball 3
Start to aspirate the thrombi got off by vibration, thrombi enters supervisor 5 by suction hole 31, some thrombis are larger, from level to level
Diaphragm 8 can be gradually disengaged big thrombi, and thrombi is made to become smaller, and prevent thrombi blocking supervisor 5, influence pumping efficiency.In addition, this
Invention is equipped with pressure sensor 13 in diaphragm 8, and supervisor 5 is hollow bimetallic tube, and the conducting wire of pressure sensor 13 passes through supervisor's 5
Hollow space is connect with external controller 14, and pressure sensor 13 passes through thrombi the pressure of diaphragm 8, passes to controller
14, when thrombi is larger, the pressure of generation is big, is easy obstruction conduit 17；When thrombi is smaller, pressure is smaller.By supervising in real time
The value of measuring pressure sensor, be capable of indirect gain thrombus number and size, thus controller adjust blood vessel display 16 on
Ultrasonic power changes 2 vibration frequency of injection block to change the size of thrombi and improves the efficiency of aspirate thrombi.Meanwhile
Under positive pressure, thrombolysis medical fluid enters in support ball 6, and support ball 6 props up blood vessel, and thrombolysis medical fluid is into inner tube 4 is crossed, from injection block 2
Injection orifice 21 enters at thrombi, and starting thrombus block makes thrombi faster under physical shock and chemicals, more thorough
Bottom falls off, and high efficiency is completed to remove thrombi.
Further, 5 inner wall perimeter surfaces of supervisor are equipped with several diaphragms 8, are gradually disengaged massive, prevent blocking supervisor 5.
Further, support 12 is molded by polycarbonate, and making material is from a wealth of sources, and production cost is low.
Further, inner tube 4 can be mono-layer tube, or multilayer pipe can inject different types of Thrombolytic Drugs simultaneously
Agent.
Further, 7 surface of outer tube is coated with coating, and the coating is superslide coating, silicone coating or anticoagulant coatings, prevents
People is damaged, safety is improved.
Further, pressure sensor 13 is equipped in diaphragm 8, pressure sensor 13 passes through supervisor 5 and external controller 14
Connection, reflects catheter interior pressure condition at any time, convenient for adjusting.
Further, the supervisor 5 is bimetallic tube, for the connection between controller 14 and pressure sensor 13.
Further, the system of novel aspirate thrombi conduit, system include novel aspirate thrombi conduit, 15 and of intelligent machine arm
Controller 14, described 15 one end of intelligent machine arm are equipped with the blood vessel display 16 with supersonic generator；The controller 14
The pressure sensor 13 being electrically connected on diaphragm 8, controller 14 are electrically connected intelligent machine arm 15, and the blood vessel display 16 will scheme
Picture and location information are sent to controller 14, and controller 14 controls intelligent machine arm 14 and follows conduit mobile；Open ultrasonic wave, note
It penetrates block 2 and starts microseismic activity；Pressure sensor 13 is equipped in the diaphragm 8, pressure sensor 13 is thrombi by diaphragm 8
Pressure passes to controller 14, and controller 14 adjusts ultrasonic power, changes the vibration frequency of injection block 2.
Intelligent machine arm 15 is controlled with conduit movement, tune different according to the pressure of pressure sensor 13 by controller 14
Save the ultrasonic frequency on blood vessel display 16.Blood vessel display with supersonic generator refers to, aobvious in original blood vessel
