Abstract

The utility model discloses an optical fiber transmission probe assembly for a medical instrument. The optical fiber transmission probe assembly comprises an optical fiber probe body (6), a connecting head (4) and a lead wire (5), wherein the lead wire (5) is connected with the optical fiber probe body and the connecting head, and is a metal spiral wire; a wire core of the lead wire consists of a reinforcing rib (1) and six optical fibers (2); the cross section of the reinforcing rib is a hexagon, and a circular arc-shaped recess is formed in each edge of the hexagon; the cross section of the reinforcing rib is provided with six circular arc-shaped recesses; the six optical fibers are circumferentially distributed on the periphery of the reinforcing rib at equal intervals; a section of outer wall of each optical fiber is positioned in the corresponding circular arc-shaped recess; every two adjacent optical fibers are tangent; the periphery of the wire core are sleeved with a plurality of rubber fastening rings (3) at equal intervals in the length direction of the wire core; the interval between two adjacent rubber fastening rings of the wire core is 50 mm. The optical fiber transmission probe assembly for the medical instrument is high in reliability, strong in bending resistance and high in anti-interference capacity.

Description

A kind of for medical apparatus and instruments fiber-optic transfer probe assembly

Technical field

This utility model relates to a kind of for medical apparatus and instruments fiber-optic transfer probe assembly.

Background technology

The existing optical fiber probe that leads, the very large problem existing is that optical fiber can not get good protection, easily bending, easily fracture, optical fiber can not well be located in conducting wire, easily makes optical signal occur deviation in transmission, and therefore measurement result is inaccurate, therefore, be necessary to design a kind of novel for medical apparatus and instruments fiber-optic transfer probe assembly.

Utility model content

Technical problem to be solved in the utility model is to provide one for medical apparatus and instruments fiber-optic transfer probe assembly, and it is high that this is used for medical apparatus and instruments fiber-optic transfer probe assembly reliability, and bend resistance and capacity of resisting disturbance are strong.

The technical solution of utility model is as follows:

A kind of for medical apparatus and instruments fiber-optic transfer probe assembly, comprise fibre-optical probe body (6), union joint (4) and be connected the conducting wire (5) of fibre-optical probe body and union joint; In fibre-optical probe body, be integrated with light source and Fibre Optical Sensor;

Described conducting wire adopts wire spiral, and the core of conducting wire is made up of reinforcement (1) and 6 optical fiber (2); The cross section of reinforcement is the hexagon that each sideband has circular arc depressed part, and the cross section of reinforcement has 6 circular arc depressed parts; 6 optical fiber are equidistantly circumferentially distributed in the periphery of reinforcement, and 6 optical fiber all have one section of outer wall to lay respectively in 6 described circular arc depressed parts, and every two adjacent optical fiber are tangent; The periphery of core is equidistantly set with multiple rubber tight loops (3) along the length direction of core, between adjacent core rubber tight loop, is spaced apart 50mm.

Beneficial effect:

Of the present utility model for medical apparatus and instruments fiber-optic transfer probe assembly, its reinforcement adopting has feature lightweight and that intensity is high, can not be bent by effective guarantee optical fiber, in addition, reinforcement be circumferentially with 6 circular arc depressed parts and 6 optical fiber adaptations, prevent that optical fiber from circumferentially moving, for optical fiber provides better location, thereby ensure that optical signal transmission is stable and reliable; The rubber tight loop of spaced set ties core, prevents between optical fiber and optical fiber, and between optical fiber and reinforcement, larger relative displacement occurs, and has better fixing and locating effect than the crust parcel core with common.In addition, wire spiral can provide good protective effect to the core of conducting wire, and therefore this easy to implement for medical apparatus and instruments fiber-optic transfer probe assembly, reliability is high, and bend resistance and capacity of resisting disturbance are strong.
