Below in conjunction with specification drawings and specific embodiments, this utility model is illustrated.
Detailed description of the invention
See Fig. 1, manual thrombus suction catheter of the present utility model comprises the coaxial suction control piece 3 connected successively, conduit 2 and suction joint 1, described suction joint 1 can carry out coaxial rotation relative to conduit 2, because original suction joint is all the structure being similar to " the Pen nib place shaft of a writing brush " opening, only can have suction force to a direction, so suction joint 1 of the present utility model is while rotation, the invariant position of conduit 2, so both ensure that suction path was smooth and easy, the change of aspirating angle can also be carried out at Ink vessel transfusing, meet the pumping requirement of different thrombosis positions,
Structure due to blood vessel is columniform body, concrete, the angle that suction joint 1 carries out coaxial rotation relative to conduit 2 is 360 °, can carry out extracting without dead angle to the thrombosis of endovascular any position, not only facilitate operator, the rehabilitation tool for patient is very helpful;
See Fig. 2 and Fig. 4, suction joint 1 is connected with conduit 2 is movable, suction joint 1 is the body of one end with the irregular oval oral area of bias, similar arranges mouth in the nib of the pen shaft of a writing brush, the suction joint of such setting is when entering the blood vessel of patient, resistive drag force is strong, simultaneously under the drive of guiding seal wire, guidance quality might as well, in order to the control of carrying out suction joint 1 rotation that can be artificially autonomous, the outer tube wall of suction joint 1 is wound with and controls seal wire 102, control one end end winding support of seal wire 102 on the outer tube wall of suction joint 1, the other end controlling seal wire 102 stretches out outside patient body along conduit 2, by the strength of doctor's hand, control seal wire 102 is made to carry out seesawing of straight line along the axis of conduit 2, carry out coaxial circumference with regard to suction joint 1 can be driven to rotate,
The mode of traditional use thrombus suction catheter first an elongated guiding seal wire is goed deep into Ink vessel transfusing, after arrival needs the position of aspirate thrombi, be set in the guiding seal wire intravasation of on guiding seal wire and edge by end of conduit being overlapped the transparent plastic sleeve had again, structure of the present utility model is, conduit 2 outer wall arranges guiding seal wire positioning pipe 201 vertically, suction joint 1 and conduit 2 can be inducted into Ink vessel transfusing through seal wire positioning pipe 201 by guiding seal wire during use, and controlling to be connected with the first spring 101 between the fixed connection point of seal wire 102 and suction joint 1 and guiding seal wire positioning pipe 201, only need when operating like this to pull to controlling seal wire 102 control just realizing rotating suction joint 1, when not needing to rotate, unclamp the pulling force of hand, original position is automatically replied under the pulling of the first spring 102, convenient control,
In order to realize good control effects, guiding seal wire positioning pipe 201 is across the junction of suction joint 1 with conduit 2, first spring 101 is crossed strip, and connect the first spring 101 suction joint 1 on site with leading the site on seal wire positioning pipe 201 on the same straight line perpendicular to conduit 2 axis, and rubber membrane 2010 is set at the mouth of pipe of guiding seal wire positioning pipe 201, like this when the seal wire that leads is through guiding seal wire positioning pipe 201, passed again by the rubber membrane 2010 punctured above, guiding seal wire frictional force is not only given in the setting of rubber membrane 2010, be convenient to fix, and the guiding seal wire positioning pipe wrapped up can not damage to blood vessel,
See Fig. 3 and Fig. 5, in order to better control of aspirating endovascular thrombosis, suction control piece of the present utility model comprises syringe adapter and spring button 301, spring button 301 is embedded on the sidewall of syringe adapter, syringe adapter and conduit 2 inner chamber and aspirate joint 1 inner space, by mounting of syringe on syringe adapter, to conduit suction force, thus endovascular thrombosis can be extracted out along conduit;
In order to avoid controlling the injury of seal wire 102 when catheter lumen or Ink vessel transfusing activity to blood vessel, conduit 1 wall is axially embedded with along catheter wall and controls guidewire lumen 202, control seal wire 102 to be connected with spring button 3 through controlling guidewire lumen 202, spring button 3 comprises button 3010 and the second spring 3011 under being arranged on button 3010, controls seal wire 102 and also can move relative to button 3010 through button 3010;
When not carrying out the control of aspirating joint rotation, button 3010 blocks the connected space controlling guidewire lumen 202, controls seal wire 102 and can not move under the constraint of button 3010; When needing the control carrying out aspirating joint rotation, the space controlling guidewire lumen 202 exposes by pressing button 3010, control seal wire 102 can be moved freely, after suction joint 1 turns to the position of needs, release button 3010 just can carry out aspirating the locked of joint 1 turned position, uses very convenient; Meanwhile, arrange bracelet 103 controlling the outer end that seal wire 102 stretches out spring button 3, the setting of bracelet 103 can not only carry out controlling the observation whether seal wire 102 resets, and facilitates hand to control it simultaneously.
See Fig. 6, a kind of to realize suction joint 1 be clamping with the movable structure be connected of conduit 2, by the cocked bead of conduit 1 mouth of pipe and the scrobicular ring on suction joint 2, and both realizations clamping, but suction joint 1 can not be hindered to carry out circumferential rotating relative to conduit 2.
