Abstract
The utility model relates to a delivering device which places an artificial tube cavity or a supporting rack in a tube cavity, belonging to a medical device. The device is mainly composed of a sheath and a pushing rod, wherein, the pushing rod is positioned in the sheath; the inner wall of the sheath is matched with the outer wall of the pushing rod; the pushing rod can be pushed in the sheath; a mark line which is impermeable to X-rays is arranged in the axial direction on the rod wall of the pushing rod. The utility model, which has a directional prompt, ensures accurate positioning and improves curative effect.
Description
This utility model is a kind of artificial tube chamber or support to be positioned over the intraluminal device of sending into, and belongs to a kind of medical apparatus and instruments.
At present,, often need insert support or artificial tube chamber, make to keep normally unobstructed in the tube chamber, the effect of playing treatment or alleviating patient's misery at diseased region treating some pipeline diseased region, especially tumors, due to illness becoming narrow or damaged in the duct chamber that causes.And putting into of artificial tube chamber or support often needs to send into device as instrument, and artificial tube chamber or support are sent into.The existing device of sending into generally comprises and sends into device sheath and push rod two parts, push rod cooperates with the sheath of sending into device, as syringe-like, usually artificial tube chamber or support are pressed on the front end of sending into the device sheath, push rod is positioned at thereafter, and device to be sent into pushes predetermined position in the tube chamber, can artificial tube chamber or support be sent in sheath by push rod, artificial tube chamber or support are opened at predetermined position, fit tightly with tube wall.Though this process can make support locate at intraluminal axial direction, but position in a circumferential direction can't be determined, especially send into distance than long time, in sending into process, send into device in always angled variation of circumferencial direction, promptly make support that certain rotation is arranged, this is for centrosymmetric support, as cylindrical artificial tube chamber or support, the variation of this angle is unimportant, but for asymmetrical artificial tube chamber or support, the anglec of rotation of artificial tube chamber of control or support is vital in sending into process, and existingly send into the intensity of variation that device can not be judged angle, thereby can't revise.
The purpose of this utility model is that a kind of intracavity stent of design is sent into device, and it is rational in infrastructure, can show and judge the windup-degree in the process of sending into, and makes to put into support or artificial tube chamber accurate positioning.
The designed intracavity stent of this utility model is sent into device and is made of sheath and push rod, and push rod is positioned at sheath, and the inwall of sheath cooperates with the outer wall of push rod, and push rod can be passed in sheath, has the mark line of X-ray opaque on the axis direction of the bar wall upper edge of push rod.
The designed intracavity stent of this utility model send in the device on the push rod with mark line be attached at the bar wall appearance of push rod or embed in the bar wall or and be machined in one with the bar wall.
The push rod that the designed intracavity stent of this utility model is sent into device has the hole of axis direction, so that put into guide wire or conduit.
The designed intracavity stent of this utility model is sent into device, and to send into the device use identical with existing intracavity stent when using, but because it has mark line, therefore direction-free symmetric cylindrical artificial tube chamber or support not only can be pushed, the artificial tube chamber or the support that have the direction sent into to require of asymmetry can also be pushed.When artificial tube chamber that the direction requirement is arranged that pushes asymmetry or support, push in tube chamber by the X-ray irradiation, because mark line is an X-ray opaque, therefore can obviously see the position at mark line place, when sending into device and twist, mark line can demonstrate it and depart from predetermined direction, and can in time adjust and send into device this moment, makes it to get back on the predetermined direction.When arrival is scheduled to put the tube chamber place of artificial tube chamber or support, keep the angle in the precalculated position of asymmetric artificial tube chamber or support not change like this, after artificial tube chamber or support placement, can reach predetermined requirement, to reach optimum therapeuticing effect.
The advantage that the designed intracavity stent of this utility model is sent into device is:
1. simple in structure, have the directivity prompting, be easy to control the placement direction of sending into artificial tube chamber or support;
2. guidance quality is strong, and easy operating improves therapeutic effect, avoids the change of placement direction and the adverse consequences that causes.
The designed intracavity stent of this utility model is sent into device and is applicable to that mainly a propelling movement symmetric figure or an end are the artificial tube chamber or the support of asymmetry.
Fig. 1 is the structure chart that the designed intracavity stent of this utility model is sent into device.
Fig. 2 is the structure chart that the designed another kind of intracavity stent of this utility model is sent into device.
Structure and the embodiment of in conjunction with specific embodiments the designed intracavity stent of this utility model being sent into device with reference to the accompanying drawings is described further below.
Embodiment 1
Intracavity stent is as shown in Figure 1 sent into device, mainly is made of sheath 1 and push rod 2, be embedded with the mark line 3 of the dotted line shape of axis direction at the outer wall of push rod 2, and mark line 3 is an X-ray opaque, and push rod 2 is positioned at sheath 1, and push rod 2 can be slided in sheath 1.When using, an end is had the artificial tube chamber of direction or support be compressed in end in the sheath 1, push rod 2 forward propelling movement ends are positioned at thereafter.Pusher is sent in tube chamber in the process, because tube chamber may be very long, therefore has the rotation of certain angle at the process of propelling movement mesotheca 1, and can be observed mark line 3 by x-ray fluoroscopy this moment departing from of respective angles, can artificially in time adjust the angle of sending into device.When sending into device and reach the precalculated position, its position is with desired to send into the position consistent, push rod 2 is passed forward, the artificial tube chamber or the support of sheath 1 front end are pushed out in the tube chamber, its angle just with matching of requiring, tube chamber fits tightly in artificial tube chamber or support and the body, plays best therapeutic effect.This intracavity stent is sent into device and is easy to direction control, and symmetric or asymmetrical artificial tube chamber or support all can be sent into, and sends into device with existing intracavity stent and operates identical, easy to use.
Intracavity stent is as shown in Figure 2 sent into device, with the structural similarity of embodiment 1, mainly is made of sheath 1 and push rod 2, and push rod 2 is positioned at sheath, and different is the surface that mark line 3 is attached at push rod 2, is the tinsel of an X-ray opaque.The hole 4 that has axis direction at the center of push rod 2.The intracavity stent of this structure is sent into utensil occupation mode and the advantage identical with embodiment 1, and because it has hole 4, therefore can put into conduit 5 by hole 4, is more conducive to intracavity stent and sends into device and inwardly push.
Claims (3)
1. an intracavity stent is sent into device, is made of sheath and push rod, and push rod is positioned at sheath, and the inwall of sheath cooperates with the outer wall of push rod, and push rod can be passed in sheath, it is characterized in that: the mark line that has X-ray opaque on the axis direction of the bar wall upper edge of push rod.
2. intracavity stent according to claim 1 is sent into device, and its feature also is: on the push rod with mark line be attached at the bar wall appearance of push rod or embed in the bar wall or and be machined in one with the bar wall.
