Abstract
The utility model relates to a novel coronary artery secular dilation catheter which comprises a far-end inner tube, and the furthest end of the far-end inner tube is connected with a section of end tube with developing performance, wherein the end tube with developing performance is a soft elastic end tube which is made of developing materials or processed after adding developing materials. The novel coronary artery secular dilation catheter has the structure that the end tube with developing performance is arranged on the furthest end of the far-end inner tube, which ensures that doctors inspect the entering position of the top end of the catheter inside a blood vessel; particularly, when the propulsion is blocked, the doctor can directly see the blocking state of the end head of the top end, and then the doctor can do corresponding adjustment to ensure that the catheter have admirable passing ability so as to reduce the operation risk. The utility model is simple and smart, and has strong practicability.
Description
Technical field
This utility model relates to a kind of coronary artery sacculus dilating catheter, and it belongs to disposable medical instrument, the intervention balloon dilatation when being mainly used in the treatment coronary stricture.
Background technology
The coronary artery sacculus dilating catheter of the present world and domestic use, its top end pipe is common non-development material and makes.In use, the doctor can't know that catheter tip is in the accurate position in the human body artery pipe, also can't know concrete reason when occurring advancing when being obstructed, and makes operating difficulty increase, and increases the risk of operation.There is not contraction elasticity because of common conduit end pipe in addition, cause conduit well not wrap on guiding wire, thereby formed a tangible step with guiding wire, when conduit need be by the narrow especially pathological changes of some arterial, the step of end pipe can be blocked by narrow position and can not pass through, and has further strengthened the risk of operation.
Summary of the invention
The purpose of this utility model is intended to overcome the concrete in-position that can not indicate catheter tip of above-mentioned existing conduit, and be difficult for deficiency by special narrow pathological changes position, a kind of conduit is provided, make the doctor in use can clearly know the concrete in-position of catheter tip, and can be easy to by special narrow pathological changes.
The technical scheme that realizes above-mentioned purpose is: a kind of novel coronary artery sacculus dilating catheter, comprise pipe in the far-end, and in far-end, be connected with the end pipe of a bit of tool development on the distal-most end of pipe.
The end pipe of described tool development is by developing material or is added with the elastic end pipe of soft belt that the developing material post-treatment becomes.
The end pipe of described tool development is the metal end pipe, and the metal end pipe is fixedlyed connected with the distal-most end of pipe in the far-end.
Described fixedly connected be to be threaded.
The end pipe of described tool development is made up of metal end pipe and nonmetal elastic tip pipe, and nonmetal elastic tip pipe is the extension of the distal-most end of pipe in the far-end, and the metal end pipe is fixedlyed connected with nonmetal elastic tip pipe.
The female thread of metal end pipe is connected with the external screw thread of nonmetal elastic tip pipe.
Its internal diameter size of the end pipe of described tool development is designed to have matched in clearance closely with the fit tolerance of the external diameter of guiding wire, or the interference fits of pine.
Adopt technique scheme, (development is meant do not have penetrance when carrying out various x-ray fluoroscopy, because the existence of this material and shading by connecting a bit of end pipe with tool development on the distal-most end of pipe in distal end of catheter.), conduit after order improves produces following beneficial technical effects: (1) doctor is when operation, end pipe by the tool development, make the doctor can observe catheter tip in endovascular in-position, particularly when advancing the Shi Nengling doctor that is obstructed to see the situation of being obstructed of termination, top intuitively, and corresponding adjustment, make conduit have splendid trafficability characteristic, and reduce operation risk.(2) because the top increases by one section resilient end pipe of softness, make conduit by pathological changes the time end pipe can hard-pressed bale on guiding wire, make the step between itself and guiding wire very little, easier by extremely narrow lesion locations.This utility model is simple, ingenious, practical.
The drawing explanation
Fig. 1 is a kind of structural representation of novel coronary artery sacculus dilating catheter.
Fig. 2 is the structure for amplifying sketch map at the novel coronary artery sacculus dilating catheter of Fig. 1 left end position.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2, a kind of novel coronary artery sacculus dilating catheter, it is mainly by the needle stand 1 of the band quick change screw thread of near-end, the stress tube 2 that is connecting a band lubricant coating, the far-end outer tube 3 that on the far-end of stress tube 2, is connecting a band dilating sacculus 5, in far-end outer tube 3, be equipped with in the far-end that passes dilating sacculus 5 and manage 4, on far-end outer tube 3, have an otch 7, the proximal port of pipe 4 and otch 7 are for being tightly connected in the far-end, gas leakage when being used to prevent dilating sacculus 5 expanded, the distal end of pipe 4 is connected with the end pipe 6 of one section tool development in far-end, the end pipe 6 of tool development is the soft belt elastic tip pipe that is processed into by developing material, guiding wire penetrates from otch 7 manages in 4 in the far-end, the internal diameter size of the end pipe 6 of tool development is designed to have matched in clearance closely with the fit tolerance of the external diameter of guiding wire, or the interference fits of pine.
As required, the end pipe of tool development also can be by being added with the elastic end pipe of soft belt that the developing material post-treatment becomes.Thereby the end pipe can be the nonmetal end pipe of metal end pipe or tool development.
The end pipe of tool development is the metal end pipe, the distal-most end of pipe in metal end pipe and the far-end is threaded or adopts alternate manner to fixedly connected.
The end pipe of tool development also can be mixed by metal end pipe and nonmetal elastic tip pipe, nonmetal elastic tip pipe can adopt the extension of the distal-most end of pipe in the far-end, and the female thread of metal end pipe is connected with the external screw thread of nonmetal elastic tip pipe or adopts alternate manner fixedly connected.
