The invention aims to at least solve one of the technical problems in the prior art, and provides a method for replacing a sheath tube, which avoids the use of a stiffened guide wire as a support for replacing the sheath tube, avoids the phenomena of dislocation, loop striking and the like of the stiffened guide wire, and improves the replacement efficiency of the sheath tube.
The technical scheme adopted by the invention for solving the technical problems is as follows: a method of replacing a sheath, comprising the steps of: placing a guide wire, a catheter and a sheath tube into a blood vessel, so that the guide wire is sleeved in the catheter, and the catheter is sleeved in the sheath tube;
removing the sheath tube and the horn mouth of the catheter;
a new sheath tube core which can be sleeved on the catheter is replaced in the new sheath tube to be replaced;
extending the new sheath and the new sheath core along the catheter into the blood vessel;
the new sheath core is removed to leave the new sheath in the vessel.
The technical scheme at least has the following advantages or beneficial effects: this application need not change the stiffening seal wire and guide the sheath pipe of treating the change as the support, but change a new sheath pipe core that can adapt to the pipe external diameter to the pipe is for supporting to guide new sheath pipe and new sheath pipe core to put into, and the step of changing the stiffening seal wire has been saved to the centre, makes the whole step of changing simpler, has avoided the use of stiffening seal wire, so also can not appear the dislocation, beat the emergence of phenomenons such as tong "pan", improve sheath pipe and change efficiency.
Further as an improvement of the technical scheme of the invention, the inner diameter of the replaced new sheath core in the new sheath to be replaced is larger than or equal to the outer diameter of the catheter.
As a further improvement of the technical scheme of the invention, the bell mouth of the conduit is detachably connected with the conduit.
As further improvement of the technical scheme of the invention, the bell mouth of the conduit is connected with the conduit through a buckle or a thread.
As a further improvement of the present invention, the outer diameter of the guidewire is 0.035 inches.
As a further improvement in the present invention, the inner diameter of the catheter is 0.035 inches.
Drawings
The invention will be further described with reference to the accompanying drawings in which:
FIG. 1 is a schematic view of the structure of a catheter in one embodiment of the invention.
Detailed Description
Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
In the present invention, if directions (up, down, left, right, front, and rear) are described, it is only for convenience of describing the technical solution of the present invention, and it is not intended or implied that the technical features referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, it is not to be construed as limiting the present invention.
In the invention, the meaning of "a plurality" is one or more, the meaning of "a plurality" is more than two, and the terms of "more than", "less than", "more than" and the like are understood to exclude the number; the terms "above", "below", "within" and the like are understood to include the instant numbers. In the description of the present invention, if there is description of "first" and "second" only for the purpose of distinguishing technical features, it is not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the precedence of the indicated technical features.
In the present invention, unless otherwise specifically limited, the terms "disposed," "mounted," "connected," and the like are to be understood in a broad sense, and for example, may be directly connected or indirectly connected through an intermediate; can be fixedly connected, can also be detachably connected and can also be integrally formed; may be mechanically coupled, may be electrically coupled or may be capable of communicating with each other; either as communication within the two elements or as an interactive relationship of the two elements. The specific meaning of the above-mentioned words in the present invention can be reasonably determined by those skilled in the art in combination with the detailed contents of the technical solutions.
Referring to fig. 1, a conventional sheath insertion method includes: firstly, a puncture needle is used for puncturing skin to enter a blood vessel, then a guide wire is arranged in the puncture needle in a penetrating mode, so that the guide wire enters the blood vessel, the puncture needle is removed, a sheath tube and a sheath tube core are sleeved together in vitro, the sheath tube and the sheath tube core are arranged in the blood vessel in a penetrating mode along the guide wire, finally the sheath tube core is removed, the sheath tube is left in the blood vessel, the establishment of a channel is completed, the catheter 2 is operated before the sheath tube is replaced, the catheter 2 is arranged outside the guide wire in a sleeved mode, and the catheter 2 is arranged in the sheath tube in a sleeved mode.
When the sheath needs to be replaced: the stiffened guide wire is removed at first, then the catheter 2 is removed, the sheath tube and the sheath tube core which need to be replaced are sleeved together outside the body, then the sheath tube and the sheath tube core are put together along the stiffened guide wire, and finally the sheath tube core is removed, so that the newly replaced sheath tube is left in the blood vessel.
In order to solve the technical problem, the invention provides a method for replacing a sheath, wherein the steps of placing a guide wire, a catheter 2 and a sheath into a blood vessel are the same as the steps, and the step of replacing the sheath is as follows: firstly, the bell mouth 1 of the sheath tube and the catheter is removed, a new sheath tube core which can be sleeved on the catheter 2 is replaced in a new sheath tube to be replaced, then the new sheath tube and the new sheath tube core stretch into the blood vessel along the catheter 2, and finally the new sheath tube core is removed, so that the new sheath tube is left in the blood vessel, therefore, the stiffened guide wire does not need to be replaced as a support to guide the new sheath tube to be replaced, but a new sheath tube core which can adapt to the outer diameter of the catheter 2 is replaced, the catheter 2 is used as a support to guide the new sheath tube and the new sheath tube core to be placed, the step of replacing the stiffened guide wire is omitted in the middle, the whole replacing step is simpler, the sheath tube replacing efficiency is improved, the phenomena of dislocation, loop beating and the like in the stiffened guide wire replacing process are avoided, and the sheath tube can be successfully replaced.
In some embodiments, the inner diameter of the replaced sheath core in the new sheath to be replaced is larger than the outer diameter of the catheter 2, so that the new sheath can be adapted to the catheter 2 conveniently, and the new sheath can be better adapted to the catheter 2.
In the present invention, the inner diameter of the replaced sheath core in the new sheath to be replaced is equal to the outer diameter of the catheter 2, and the catheter 2 has certain elasticity, so that the two sheaths are matched more tightly.
In the present invention, the guidewire has an outer diameter of 0.035 inches and the catheter 2 has an inner diameter of 0.035 inches, and the guidewire is capable of passing through the catheter 2.
The horn mouth 1 and the pipe 2 of pipe can be dismantled and be connected, make things convenient for the horn mouth 1 of pipe to dismantle like this, and is specific, can be the buckle connection between the horn mouth 1 of pipe and the pipe 2, also can be threaded connection etc..
Of course, the present invention is not limited to the above embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
