Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings: an in-tube longitudinal wave thrombolytic device as shown in fig. 1 and 2 is provided with a base 12, a pushing motor 9 and a syringe 13.
The base 12 is used as a receiving seat for the injector 13 and the pushing motor 9, and also plays a role in guiding and fixing injection pushing of the injector so as to realize independent automatic operation of the equipment.
The base 12 is provided with a linear guide groove 11, the linear guide groove 11 is embedded with the bottom of a syringe seat 10 capable of moving along the linear guide groove, and the syringe seat is used for limiting the movement of the syringe to do linear movement only within a limited range. The syringe seat 10 is provided with a syringe groove parallel to the linear guide groove 11, and the syringe 2 of the injector 13 is partially embedded in the syringe groove. The needle cylinder groove can be a through hole for limiting the freedom degree of the needle cylinder, so that the needle cylinder can only move along the axial direction, and also can be a blind hole with one end closed, and the needle cylinder is fixedly embedded in the needle cylinder groove. The syringe seat can move along the linear guide groove, and when the syringe groove is a through hole, the syringe 2 embedded in the syringe seat can independently move along the same direction.
The straight guide groove 11 is penetrated through the front end of the base 12, so that the syringe seat 10 and the transducer seat 7 can slide out from the front end of the straight guide groove 11 for maintenance and replacement.
The syringe is embedded with a matched syringe piston cylinder 3, and the syringe 2 and the piston cylinder 3 are respectively provided with a syringe handle 4 and a tail 5 which are radially protruded at the tail end. The diameter of the needle cylinder handle is larger than the inner diameter of the needle cylinder groove, the needle cylinder is limited to move forward and cannot exceed the needle cylinder seat, and the tail fin is convenient to fix with the transducer seat. In order to reduce the sliding resistance between the syringe and the piston cylinder, the syringe 2 or the piston cylinder 3 of the injector 13 is made of polytetrafluoroethylene, so that the conditions of heat generation, desquamation or movement obstacle and the like can be avoided, and the movement obstacle can cause abrupt pressure change in the catheter and should be avoided as much as possible.
As shown in fig. 2, when the syringe slot is a through hole, the top of the syringe seat 10 is provided with a split joint 18 along the direction parallel to the linear guide slot 11, the split joint separates the syringe seat to two sides into two parts with split top, and the two parts can be buckled or attracted into a whole through magnetic materials at the split joint to form a complete syringe slot, or can be taken out and replaced conveniently after being separated.

The transducer seat 7 is internally provided with a transducer, one side of the transducer seat 7 facing the injector is provided with a lock catch 6 for fixedly connecting the tail fin 5 of the injector piston cylinder and enabling the tail fin 5 to be clung to a transduction piece of the transducer, or the transduction piece is fixedly connected with the tail fin through a rigid medium; when the transduction piece is electrified to work, longitudinal waves are conducted to liquid in the syringe 2 along the tail wing 5 and the piston cylinder 3 of the injector, and then are conducted into the embedded catheter along a straight line through the catheter 1 connected with the front end of the syringe, so that thrombus formed in the catheter cavity is cleared.
A push rod 8 is fixed or integrally arranged on the opposite side of the transducer seat 7 and the lock catch 6, and the push rod 8 is arranged in parallel with the linear guide groove 11. The pushing motor 9 is arranged on the push rod side of the transducer seat 7, when the pushing motor is a rotating motor, the push rod is connected with an output shaft of the rotating motor through a thread pair, and rotation of the rotating motor is converted into linear motion through the thread pair to push the push rod to move forwards.

When the thrombus in the catheter is completely blocked, the transducer vibrates in situ, the negative pressure state in the needle cylinder is maintained, the transducer seat is moved 2-3 mm away from the direction of the injector during starting, then the transducer is started, the transducer piece vibrates to generate longitudinal waves which can be ultrasonic waves or sound waves, the vibration impacts the thrombus in the wall of the catheter, and the thrombus is forced to be broken and fall off. A limiting block 21 is fixedly arranged on the top surface of a base 12 with the thickness of 2-4 mm behind the original position of the energy converter seat 7, and is used for starting after the energy converter seat 7 moves to the limiting block 21 when thrombus in a catheter completely blocks the catheter, so that negative pressure is generated in a syringe, in the operation process, reverse displacement and pressure difference which is formed after resetting are repeatedly generated between the syringe and a piston of the syringe and is regularly changed in negative pressure-return-to-zero-negative pressure are generated, longitudinal waves are generated, and the thrombus is impacted to break and fall off.
When the catheter is partially blocked, the piston cylinder is slowly pushed in, and the thrombolytic medicine is pushed in at the same time of longitudinal wave thrombolysis.
