Definitions
- coronary arteries are known to play an important role in supplying oxygen and nutrients to the heart muscle.
- the population with many coronary artery disease is increasing due to irregular eating habits or stress.
- the catheter only performs a function of emitting the light transmitted from the optical coherence tomography apparatus, and it may be difficult to generate and emit the light by itself. Therefore, conventionally, a fixed optical coherence tomography apparatus and a catheter are connected using a rotary joint or the like. However, according to the prior art, various lines are provided around the motor provided for rotation of the catheter, and various problems such as vibration and noise may occur.
- the present disclosure is intended to provide an optical coupling device having a rotational coupling structure, which has been devised in response to the above-described background art.
- FIG. 1 is a front view for explaining an example of an optical coupling device according to some embodiments of the present disclosure.
- FIG. 3 is a view showing a detailed view of FIG. 2 for explaining an example of an optical coupling device according to some embodiments of the present disclosure.
- FIG 8 is a front view for explaining an example of a fiber connector according to some embodiments of the present disclosure.
- the fixing unit 100 may include a first optical path 141 having an optical end pointing in a downstream direction.
- the downstream direction may be a direction toward a downstream rotational light path (catheter).
- the first optical path 141 having an optical end may be a static signal path (a non-rotating signal path) transmitted from the optical coherence tomography apparatus.
- a first bearing 250 and a second bearing 260 allowing the rotor 211 of the motor 210 to rotate are provided. can be provided.
- the first side surface 1100 may provide a first optical junction 150 .
- the first optical junction 150 may be an optical junction between the fixed light source 140 and the second optical path 270 .
- the fiber connector body 331 may form the outer shape of the fiber connector 330 .
- the fiber connector body 331 may be formed in a hollow pipe shape. In this case, a portion of the rotor 211 of the motor 210 may be inserted into the fiber connector body 331 .
- the present invention is not limited thereto.
- the fiber connector 330 may include a pair of fingers 336 .
- the pair of fingers 336 may fix the downstream rotational light path (not shown) or separate the downstream rotational light path according to a position at which a pin (not shown) is positioned in the slot 334 .
- the second weight part 3422 provided at one end of the second coupling part 3423 is coupled to the first finger ( 3361) may exist in the location direction.
- the weight may be concentrated on the second weight part 3422 of the second counter weight 342 .
- the centrifugal force of the second weight part 3422 may be generated in a direction opposite to the centrifugal force of the second finger 3362 generated as the rotating part 200 rotates.
- the second weight part 3422 may have a predetermined weight to generate a centrifugal force greater than the magnitude of the centrifugal force of the second finger 3362 .
