Specific embodiment
Technical solution of the present invention is described in detail with reference to the accompanying drawing.
Embodiment 1, the present invention provides a kind of microtubulars, referring to fig. 2, including tube socket 11, pipe shaft 13 and ferrule 14, pipe
The preferably transparent engineering plastics with female Luer of seat are molded, and can be used for connecting with other products with female Luer
It connecing, it is preferable to use platinum i.e. platinum to make for ferrule, and described pipe shaft one end is connect with tube socket, and the other end is connect with ferrule,
It, which is connected, can be used the such as interference connection of existing mode, is integrally formed etc., and the diameter of pipe shaft head end is less than tail end (namely
Close to one end of tube socket) diameter, the mode that existing braided steel wire can be used makes, it is preferred that the pipe shaft is by head end
Diameter Gradual Change to tail end increases, and seamlessly transits the both ends of metal tube body, head end is preferably 1.2F diameter, and tail end is preferably
2.7F diameter pipe shaft, length are generally made as 140-150 centimetres, this grading structure make strength be easier to lead from tail portion transmission to
Head end, tail portion push is stronger, and in order to further increase the stability and tail portion motive force of push, referring to Fig. 3, the microtubular is also
Including diffusion-induced stress pipe 12, the diffusion-induced stress pipe sleeve is fixed on tube socket in the position of pipe shaft connecting with tube socket, described
The diameter of the head end of ferrule is less than the diameter of tail end, and the surface of the ferrule is provided with screw thread 15.
Microtubular provided by the invention, when encountering the lesion that calculus etc. is easily detected by conduit being hindered to move ahead, Ke Yitong
It crosses and rotates in the forward direction tube socket ferrule is made to pierce calculus by screw thread, it can be to rotate in the forward direction pipe again after counter-rotating tube socket when boring motionless
Seat so passes through pathological tissues, it can be seen that, microtubular passability provided by the invention is strong.
In addition, replacing rubber tip by using ferrule, and screw thread is set in ferrule, make head hardness it is high, can
Plasticity is strong, and in tube socket rotation, head is not easy to deform, fracture.
In addition, rubber tip is elastic due to having, it is easily deformed during use, so that itself and pipe shaft be made to connect
It connects insecure, squeezes seal wire when being easy to fall off, and deforming sometimes, seal wire is clamped, be easily detected by seal wire, use gold
Belong to head and solves the problems, such as this.
In the application, ferrule is preferably shuttle shape head, so that ferrule drills through lesion.
Existing microtubular, due to seal wire and interior wall friction when the hole inner wall perforating silk for perforating silk of rubber tip, because
This seal wire is not easily through for this purpose, applicant is provided with superslide coating, the superslide coating in the hole of the ferrule
Preferably PTFE (polytetrafluoroethylene (PTFE)) coating, in this way, reducing the friction of the inner wall in the hole of seal wire and ferrule, it is easier to perforate
Silk, naturally it is also possible to superslide coating be set in the pipe shaft of microtubular, the hole of the perforating silk of tube socket, in order to perforate silk.
Embodiment 2, the present invention also provides a kind of intravascular electric drill way system, including above-mentioned microtubular and motor,
The tube socket of the microtubular is connected to motor, and existing mode can be used in the connection of tube socket and motor, such as will by axle sleeve
Motor shaft connects the mode, it is preferable to use being detachably connected with tube socket, such as fixed and above-mentioned female Luer on motor shaft
The female Luer of cooperation can be equipped with a motor to multiple microtubulars in this way, and motor speed is generally limited to 0-200
Rev/min, it is powered by battery, it is preferable to use existing intelligent electric machines for motor, or use existing controller control motor
Positive and negative rotation, revolving speed etc. do not walk specific restriction herein.
Intravascular electric drill way system provided by the present application, setting motor cooperate above-mentioned microtubular structure, pass through motor generation
The dynamic push of substitute, using more convenient.
Above-described embodiment is the illustration invented, and it is special should not to describe limitation with the exemplary embodiments of specification and attached drawing
The protection scope of economic rights.
The preferred embodiments of the disclosure and embodiment are explained in detail above in conjunction with attached drawing, but it is of the invention
