Abstract
The utility model provides a disposable coupler whose optical fiber terminal is connected with the fiber output end of a treating device. The coupler is composed of a fixing chamber, an end cover and a disposable optical fiber needle head; a radial direction optical fiber retaining clip whose middle part is provided with a through hole and a conical surface through hole clipping sleeve are arranged in the optical fiber fixing chamber; the end surface of the optical fiber retaining clip is provided with a pressure spring which is contacted with the end cover of the coupler and fixes optical fiber at axial direction. The relevant position of the end cover, the fixing chamber and the disposable optical fiber needle head is provided with the through hole which is used for making the optical fiber pass through. A section of disposable optical fiber is fixed in the disposable optical fiber needle head; one end of the needle head is inserted and connected with the optical fiber fixing chamber; the other end is connected with operational terminal. The optical fiber coupler which adopts the utility model can effectively prevent the cross infection of hematogenous diseases, having the advantages of convenient replacement, safety and sanitation.
Description
The utility model relates to a kind of fibre-optic terminus coupling mechanism and belongs to the Medical Devices accessory.
At present, constantly enlarge in fibre-optic range of application medically, directly the fibre-optic terminus of the phototherapy apparatus of general tissue of contact human body and blood is in clinical practice, but its fibre-optic terminus all is the optical fiber syringe needle as intravascular irradiation that uses repeatedly through sterilization so far, laser surgey " cutter " etc., though can reach the sterilization purpose through cleaning and sterilizing, the potential danger that blood borne disease is propagated still exists, especially grass-roots unit, danger is bigger.
It is a kind of for disposable fibre-optic terminus coupling device that the purpose of this utility model is to provide, to make disposable with the fibre-optic terminus that tissue or blood contact, fiber-optic output by coupling mechanism of the present utility model and therapeutic equipment couples together, farthest reduce the light quantum loss at fiber splices place, be convenient to again change and use.
The technical solution of the utility model is to realize like this, the fibre-optic terminus coupling mechanism is by optical fiber lock chamber (4), end cap (3) and disposable optical fiber syringe needle (10) are formed, and have the radially optical fiber geometrical clamp (6) of through hole to be connected stage clip (5) with conical surface through hole cutting ferrule (7) optical fiber geometrical clamp (6) end face in the middle of being provided with in the optical fiber lock chamber and contact with axial restraint optical fiber with coupling mechanism end cap (3); At end cap, the hole is opened so that optical fiber passes through in lock chamber and disposable optical fiber syringe needle relevant position.Fixed fiber of coupling mechanism equipment output end (1) and the disposable optical fiber of terminal (12) surface of contact relevant position have water filling micropore (9), inject pure water during use to reduce the refraction loss of light.
The fibre-optic terminus coupling mechanism of employing technical solutions of the utility model can be avoided the cross-infection of germ effectively, can reduce numerous and diverse work of cleaning and sterilizing again, only disposable optical fiber syringe needle need be seated on the coupling mechanism during use to get final product, and it is convenient to change, safety and sanitation.Be particularly useful for connecting disposable optical fiber syringe needle, optical fiber scalpel, operational terminals such as fibre opic endoscope.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
