Description
Technical field
The utility model relates to interventional therapy operation medical appliance fields, and in particular to a kind of novel interposing catheter.
Background technique
Interventional therapy operation is by means of interposing catheter by vessel lumen, realizes the one of low wound diagnosing and treating to lesion
The emerging medical technology of kind.Compared with traditional medical technology, interventional therapy has the following advantages: easy to operate；Due to interventional therapy
Low-wound is avoided that and brings huge pain to patient；Because of its minimal invasive, moreover it is possible to reach the portion that routine operation cannot reach
Position；It is relatively low compared with routine operation treatment medical expense, thus widely patient and doctor are received.Present interventional therapeutic technique
Clinically it is widely used in cardio-cerebral angiography and narrow blood vessel plasty.Interposing catheter is the main of endovascular temporary embolization
One of instrument provides the transmission channel of other medical instruments and drug for interventional therapy.
Most common conduit is catheter coude and SIMMON conduit, and catheter coude is straight suitable for blood vessel, angle
Small blood vessel, SIMMON conduit is suitable for the biggish blood vessel of angle, but is meeting ox horn arcuate blood vessel and left side neck always moves
Arteries and veins and aorta situation at an acute angle, catheter coude are not available, and the tip SIMMON is too long, not easily molded, need experience very rich
Rich operator could complete, and cause inconvenient to use.
Utility model content
The purpose of the utility model is to provide a kind of novel interposing catheters, are meeting ox horn arcuate blood to solve existing conduit
The problem or inconvenient problem with use that pipe and left common carotid and aorta situation at an acute angle are not suitable for.
To achieve the above object, a kind of novel interposing catheter of the utility model adopts the following technical scheme that a kind of novel
Interposing catheter, including catheter body, catheter body include flat segments and the bending section for being set to flat segments front end, the bending section
Angle between flat segments is 30-60 °, and the length of bending section is 0.5-1.5cm, and the front end of bending section is provided with arc end
Portion.
The length of the bending section is 1cm.
Angle between the bending section and flat segments is 45 °.
On the catheter body inner wall along its length on be provided with wire drawing, before one end of wire drawing is connected to bending section
On the inner wall at end, the spin bath installed for wire drawing is provided on catheter body inner wall.
The spin bath is set in inner wall section opposite with bending angle on catheter body inner wall.
Be arranged on the inner wall of the catheter body there are two relatively extended arc suspended wall, two arc cantilevers and its
Internal catheter body inner wall section forms the spin bath.
There is gap, gap is less than the diameter of wire drawing between the end of arc cantilever described in two.
The utility model has the beneficial effects that the angle between bending section and flat segments is controlled between 30-60 °, and
The length of bending section is controlled in 0.5-1.5cm simultaneously so that the conduit can preferably use with ox horn arcuate blood vessel and
Left common carotid and aorta situation at an acute angle keep the guide function of conduit more prominent, avoid catheter coude and
SIMMON conduit is not easy the problem of forming in these cases, and above structure conduit can also preferably make new hand
With, it is upper quick-moving, with conveniently.The front end of bending section is provided with curved end, avoids when injecting contrast agent contrast agent to blood vessel
The impact of wall.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram one of one embodiment of novel interposing catheter of the utility model；
Fig. 2 is a kind of structural schematic diagram two of one embodiment of novel interposing catheter of the utility model；
Fig. 3 is the structural schematic diagram of the cross section of catheter body.
Specific embodiment
A kind of novel interposing catheter of the utility model, as shown in Figure 1-Figure 3, including catheter body, catheter body include
Flat segments 1 and the bending section 2 for being set to 1 front end of flat segments, the included angle A between bending section 2 and flat segments 1 are 30-60 °, this reality
Applying the angle in example between bending section and flat segments is 30 °.The length L of bending section is 0.5-1.5cm, bending section in the present embodiment
Length be 1cm.The front end of bending section 2 is provided with curved end 3.The conduit is preferably used and ox horn arcuate blood
Pipe and left common carotid and aorta situation at an acute angle keep the guide function of conduit more prominent, avoid singly curved lead
Pipe and SIMMON conduit are not easy the problem of forming in these cases, and above structure conduit can also be preferable for new hand
Use, it is upper quick-moving, with convenient.The front end of bending section is provided with curved end, avoids the contrast agent pair when injecting contrast agent
The impact of vascular wall.
On catheter body inner wall along its length on be provided with wire drawing 4, before one end of wire drawing 4 is connected to bending section 2
On the inner wall at end, the spin bath 5 installed for wire drawing is provided on catheter body inner wall.Spin bath 5 is set to catheter body inner wall
On face in the inner wall section opposite with bending angle.Relatively extended arc suspended wall there are two being arranged on the inner wall of catheter body
6, two arc cantilevers 6 and its internal catheter body inner wall section form the spin bath 5.Due to catheter body be it is soft,
And it is successively increased by front end to rear hardness, therefore the setting of wire drawing can change the bending angle of bending section when in use, mention
The smooth development of height operation convenient degree and intervention operation.There is gap, gap, which is less than, draws between the end of two arc cantilevers
The diameter of silk, prevents wire drawing by deviating from spin bath, and two arc cantilevers and catheter body are integrally formed, material be all it is soft,
Wire drawing can be filled in spin bath when installation.
In the other embodiments of the utility model, angle between bending section and flat segments can be 60 °, at this time can be with
It is not provided with wire drawing and spin bath；Angle between bending section and flat segments can be 45 °；The length of bending section can be 0.5cm；
The length of bending section can be 1.5cm.
