Abstract
The utility model relates to a medical composite guide wire, which comprises a sleeve provided with an infilling body inside, wherein, the filling forms of the infilling body including short cylinder set and sphericity- or polyhedron-shaped particles. When short cylinder filling form is adopted, each set of short cylinder infilling bodies are provided with central ostioles inside, while the outer brims are provided with slots; the front portion and the end portion of the rubber sleeve are respectively provided with ostioles; the material of the infilling body can be hard rubber, stainless steel, magnetic steel, plastics or other similar materials. The above arrangement makes the medical composite guide wire have stronger rigidity along the axial direction, thereby being capable to bend under the limit of human body intracavity during being led into the human body intracavity without being easily twisted; meanwhile, with less strong lateral rigidity, the guide wire is uneasy to injure human body and can reduce discomfort, thereby bringing great convenience to lead-in operation of medical care personnel.
Description
Technical field
This utility model relates to a kind of medical compound seal wire that uses in medical inspection and therapeutic process.
Background technology
Usually need to carry out import operation in the tube chamber at present in medical diagnosis and therapeutic process, there is the problem of convenient, comfortable and secure context in existing method.Need cavity (as nasal cavity, urethra etc.) is carried out import operation in clinical practice, present known seal wire is generally made with the material that plastics, metal or vulcanie etc. have certain elasticity, hardness and intensity.Because the crooked situation complexity of cavity, therefore often requiring seal wire to have less lateral thrust rigidity could allow the patient feel comfortably cool, also can reduce damage to the cavity inner wall mucosa, simultaneously because the friction and the extruding of cavity inner wall and seal wire, if seal wire rigidity in the axial direction is not enough, then import operation can compare difficulty, even can cause seal wire crooked winding in cavity.Therefore require seal wire to have higher rigidity or hardness in the axial direction, has less lateral rigidity simultaneously, and present known seal wire all is difficult to possess simultaneously less lateral rigidity and bigger axial rigidity in selection and structure design, therefore has open defect at convenient, comfortable and secure context.
Summary of the invention
In order to overcome in present medical inspection and the therapeutic process in the tube chamber the employed seal wire of import operation, when providing a kind of the operation, this utility model can alleviate patient's medical compound seal wire painful and that bring convenience for medical personnel's import operation in deficiency convenient, comfortable and that secure context exists.
In order to solve the problems of the technologies described above, this utility model has adopted a kind of medical compound seal wire, comprises sleeve pipe, is provided with obturator in the described sleeve pipe.Described obturator is filled with the form of one group of short cylinder or is filled with sphere or the particulate form of polyhedron.When filling, in every group of short cylinder obturator, be provided with central small hole, and on its outer rim, be provided with groove with the short cylinder form.Be respectively equipped with aperture at gum sleeve head and afterbody.The material of obturator can be hard rubber, rustless steel, magnet steel or plastics.
This utility model has brought following beneficial effect: the elasticity tension of this medical compound seal wire middle sleeve cooperates with the supporting role of obturator makes seal wire that bigger rigidity be arranged in the axial direction, can only be under human intracavity's constraint when in the human intracavity, importing crooked and be difficult for curling, has simultaneously less lateral rigidity again, easy damaged human body and alleviate the discomfort of human body brings great convenience for medical personnel's import operation.The central small hole of short cylindrical and the groove on the outer rim can be conveniently the circulation of disinfectant solution or sterilization gas during to compound seal wire sterilization, and the gap of polyhedron or spheroidal particle obturator also can be conveniently the circulation of disinfectant solution or sterilization gas during to compound seal wire sterilization.The circulation of disinfectant solution or sterilization gas when in addition, the aperture of sleeve pipe head and afterbody also can conveniently be sterilized to compound seal wire.

The specific embodiment
In first embodiment of this utility model shown in Figure 1, sleeve pipe 1 adopts medical grade rubber to make, and the obturator 2 of being filled in the sleeve pipe 1 is one group of short cylinder, is provided with central small hole in the short cylinder, is provided with groove on its outer rim.Head and afterbody at sleeve pipe 1 are respectively equipped with aperture 3 and 4.The circulation of disinfectant solution or sterilization gas when the central small hole of short cylindrical and the groove on the outer rim can conveniently be sterilized to compound seal wire.The circulation of disinfectant solution or sterilization gas when the aperture of sleeve pipe head and afterbody can conveniently be sterilized to compound seal wire.
In second embodiment of this utility model shown in Figure 2, sleeve pipe 1 adopts medical grade rubber to make, and the obturator 2 of being filled in the sleeve pipe 1 is one group of sphere or polyhedron granule.Head and afterbody at sleeve pipe 1 are respectively equipped with aperture 3 and 4.The circulation of disinfectant solution or sterilization gas when can conveniently sterilize to compound seal wire in the gap of polyhedron or spheroidal particle obturator.The circulation of disinfectant solution or sterilization gas when the aperture of sleeve pipe head and afterbody can conveniently be sterilized to compound seal wire.
In above-mentioned two embodiment, the material of obturator 2 can be hard rubber, rustless steel, magnet steel or plastics.
In sleeve pipe 1, pack into and make behind the obturator 2 sleeve pipe form pretension, the two ends of closed casing 1 then, the elasticity tension of sleeve pipe 1 cooperates with the supporting role of obturator 2 makes guide rod that bigger rigidity be arranged in the axial direction, can only be under human intracavity's constraint when in the human intracavity, importing crooked and be difficult for curling (referring to Fig. 5), has simultaneously less lateral rigidity again, easy damaged human body not, thus the discomfort of human body alleviated to a certain extent.
