Description
Technical field
This utility model relates to interventional medical device or equipment, refers in particular to a kind of guiding wire with identification function, and specifically, a kind of have the guiding wire that mark inserts official jargon length function.
Background technology
Interventional therapy utilizes the medical imaging equipments such as X-ray examination, CT location, B-mode ultrasonic apparatus to lead, special conduit or apparatus (intervention equipment) are arrived at diseased region in body through the natural pipeline of human body artery, vein, digestive system, biliary tract or postoperative drainage pipe, morbid state is diagnosed and topical therapeutic.Interventional therapy Applied Digital technology, expands the visual field of doctor, by conduit and seal wire, extends the both hands of doctor.Its otch (point of puncture), only has grain of rice size, need not cut tissue, just can treat manyly cannot to treat in the past, or must operative treatment, or the disease that medical treatment curative effect is not good enough, as tumor, and hemangioma, various hemorrhage etc.
Guiding wire is a kind of conventional intervention equipment.Current, guiding wire adopts stainless steel silk, stainless steel spring and plastics seal wire usually, and surface is coated with PTFE and hydrophilic coating.Enter tube chamber and be commonly referred to as head end (complete herewith anticipate) herein to one end that lesions position plays therapeutical effect, the other end, one end that namely operative doctor hands operates in vitro is commonly referred to as tail end (complete herewith anticipate) herein.Utilize X-ray to develop during operation and observe information and the pathological changes situation that guiding wire enters the concrete position of human body under the cooperation of conduit.In operation process, owing to can not sentence from (particularly plastics seal wire) guiding wire the length (degree of depth namely in head end insertosome) known in guiding wire insertosome directly rapidly, operative doctor can only observe by X-ray development the situation that guiding wire enters the concrete position of human body, so, operative doctor both necessary moment concern hands, to the operation of guiding wire, must observe X-ray development the moment, easy discrete surgical doctor attention again, increase operating time, even increase operation risk.
Therefore, a kind of guiding wire with mark insertion tube intracavity length function of market demand, operative doctor, while concern hands is to guiding wire operation, directly can be sentenced rapidly knowledge guiding wire and insert intraluminal length from guiding wire.Cause operative doctor visual cognitive ability, operating time shortens, and operation risk reduces, and operative doctor working strength also can alleviate.
Summary of the invention
This utility model technical issues that need to address overcome to sentence from guiding wire the deficiency that knowledge guiding wire inserts intraluminal length, operative doctor can only enter human body concrete position situation by X-ray development observation guiding wire directly rapidly at present, a kind of guiding wire with identification function is provided, by this guiding wire, operative doctor can directly rapid from guiding wire sentence know guiding wire insert intraluminal length.
For this reason, this utility model takes following technical proposals:
A kind of guiding wire with identification function, comprise head end section, middle part and tail end section, the head end of guiding wire is one end that guiding wire enters that tube chamber plays therapeutical effect, the tail end of guiding wire refers to operative doctor one end at people's manipulation in vitro guiding wire, described head end section is one section that comprises head end, and described tail end section is one section that comprises tail end; Be described middle part between described head end section and described tail end section; Described tail end section is shaped with the colour coding identification section of mark guiding wire insertion tube cavity length, and colour coding identification section comprises multiple colour coding subsegment, the continuous Boulez of multiple described colour coding subsegment, and their length is identical and color is different.
Preferably, described tail end section comprises tail end section main body and described colour coding identification section, and described colour coding identification section is produced on the appearance of described tail end section main body.
Preferably, described head end section comprises head end section skin and seal wire inner core, and seal wire inner core is wrapped in head end section skin; Described tail end section main body, described middle part and described head end section skin are shaped to entirety.
Preferably, multiple described colour coding subsegment external diameter is consistent.
Preferably, one or more compositions in described tail end section main body, described middle part and described head end section skin polyurethane polyurethane, thermoplastic elastomer (TPE) TPE, polyamide, polyetheramine and fluoro-containing plastic makes, form soft flexible layer, avoid scratch lumen wall or cause significant discomfort sense to patient.
Preferably, described seal wire inner core stainless steel spring or nickel-titanium alloy material make.
Preferably, the outer surface of head end section, described middle part and tail end section three is coated with hydrophilic coating, fluoropolymer coating or PTFE coating, to reduce frictional force, improves smoothness and safety.
Described colour coding subsegment represents certain intubating length, and forms the colour coding of unified easy memory.
The head end forming device of described guiding wire is definite shape.
The beneficial effects of the utility model are:
One, described tail end section is shaped with colour coding identification section, and colour coding identification section comprises multiple colour coding subsegment, the continuous Boulez of multiple described colour coding subsegment, and their length is identical and color is different.Different color segment represents different intubating lengths, operative doctor can directly rapid from guiding wire sentence know guiding wire insert intraluminal length, again need not observe X-ray development the moment, cause operative doctor visual cognitive ability, operating time shortens, operation risk reduces, and operative doctor working strength also can alleviate.
Its two, head end section adopt soft flexible material and rigid elastic balance alloy material combination, the skin of guiding wire and seal wire inner core ensure that guiding wire smoothness, rigidity, turn round control property and safety.
Its three, outermost hydrophilic coating makes seal wire superslide, has the stronger ability of passing through distortion complex lesions position.
