Description

Technical Field

[0001] The utility model relates to the technical field of imaging instruments, in particular to an optical coherence tomography imaging instrument probe. Background Art

[0002] Optical coherence tomography is an emerging optical imaging technology. The output light of a broadband light source is divided into two parts after entering the interferometer. One part reaches the sample arm through the interferometer, and the other part reaches the reference arm. The light reaching the sample arm returns to the interferometer along the original path after being scattered by the sample, and the light reaching the reference arm returns to the interferometer along the original path after being reflected by the reference reflector. Therefore, an imaging probe is required to assist the use of optical coherence tomography.

[0003] For example, in a single-spectrometer multi-beam optical coherence tomography imager with Chinese patent application number CN201921533528.X, N light beams emitted by N broadband light sources enter the corresponding three-port circulators respectively, and the light beams output from the output port of the three-port circulator are output to the interference spectrometer through the first fiber array, and are divided into sample light and reference light, which enter the sample arm and the reference arm respectively. The light reaching the sample arm returns to the interference spectrometer along the original path after being scattered by the sample; similarly, the light reaching the reference arm returns to the interference spectrometer along the original path after being reflected by the reference reflector. After interference in the interference spectrometer, the light signals returned from the sample arm and the reference arm enter the spectrometer through the first fiber array, another output port of the three-port circulator, and the second fiber array respectively. The spectrometer converts the interference light signals into electrical signals; the image acquisition device is used to collect electrical signals in the spectrometer. It has the following technical defects:

[0004] When the optical coherence tomography probe is used for imaging detection, the optical coherence tomography probe is exposed to the outside due to the lack of a device for protecting and storing the optical coherence tomography probe, which may easily cause the optical coherence tomography probe to be damaged under the action of external forces. Utility Model Content

[0005] In order to solve the problem raised in the above background technology that when an optical coherence tomography probe is used for imaging detection, the optical coherence tomography probe lacks a device for protecting and storing the optical coherence tomography probe, which may cause the optical coherence tomography probe to be exposed to the outside, thereby easily causing the optical coherence tomography probe to be damaged under the action of external force, the utility model provides the following technical solutions:

[0006] The optical coherence tomography probe comprises an imaging probe body connected to the optical coherence tomography for imaging detection, a storage tube for protecting and storing the imaging probe body is arranged at the bottom end of the imaging probe body, and a storage device for storing the imaging probe body in the storage tube is arranged in the tube cavity of the storage tube.

[0007] The storage device includes a connecting component for fixedly connecting to the imager probe body, a driving component for driving the imager probe body on the connecting component to be stored in the storage tube is provided on the side wall of the connecting component, and a connecting tube for protecting the power cord of the imager probe body is provided at the bottom end of the connecting component.

[0008] Furthermore, the connecting assembly includes a fixing rod fixedly mounted at the bottom end of the imaging device probe body for sliding in a storage tube, a limiting plate fixedly mounted at the bottom end of the fixing rod for preventing the fixing rod from escaping from the storage tube, a spring for resetting the fixing rod is mounted on the rod body of the fixing rod, and the spring is located in the storage tube.

[0009] Furthermore, the driving assembly includes a connecting block fixedly mounted on a side wall of the limiting plate, and an operating plate for driving the limiting plate to move up and down is fixedly mounted on the front end of the connecting block.

[0010] Furthermore, the imaging device probe body comprises a connection block fixedly mounted on the top end of a fixing rod, and a probe for imaging detection is arranged at the front end of the connection block.

[0011] Furthermore, a storage groove for limiting the limiting plate is opened in the tube cavity of the storage tube, a sliding groove for allowing the connecting block to move up and down is opened on the tube wall of the storage tube, and a limiting groove for locking the connecting block is arranged on the right side of the sliding groove, and the groove width of the limiting groove is the same as the groove width of the sliding groove, so that when the driving component drives the probe on the connecting component to be stored in the storage tube, the probe can be fixed by the snap connection between the limiting groove and the connecting block to prevent the probe from moving out of the tube cavity of the storage tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By providing a storage tube and a storage device, when storing the unused imaging device probe body, the limiting plate on the connecting block can be driven by the operating panel to move downward along the storage tube, so that the probe on the connecting block on the top of the fixed rod can be driven to be stored in the storage tube until the connecting block is moved to the bottom end of the slide groove, and then the operating panel is rotated to drive the connecting block to rotate in the limiting groove, and the connecting block is restricted, so that the imaging device probe body can be stored in the storage tube to prevent the probe from being damaged due to external force.

The tube cavity of the storage tube 200 is provided with a storage device 300 for storing the imaging probe body 100 in the storage tube 200.

[0025] The imaging probe body 100 includes a connecting block 101 fixedly mounted on the top of a fixing rod 311, and the cross section of the connecting block 101 is triangular, so that the imaging probe body 100 can be quickly stored in the storage tube 200 through the storage device 300 for protection, so as to prevent the imaging probe body 100 from being exposed to the outside and damaged when not in use; a probe 102 for imaging detection is provided at the front end of the connecting block 101, so that imaging detection can be performed using the probe 102.

[0026] A receiving groove 203 for limiting the limiting plate 312 is provided in the tube cavity of the storage tube 200, and the cross-section of the receiving groove 203 is a joint groove to prevent the connecting component 310 from moving out of the storage tube 200; a sliding groove 201 for the connecting block 321 to move up and down is provided on the tube wall of the storage tube 200, and the sliding groove 201 runs through the tube body of the storage tube 200 to facilitate the up and down movement of the driving component 320, and a limiting groove 202 for locking the connecting block 321 is provided on the right side of the sliding groove 201, and the groove width of the limiting groove 202 is the same as the groove width of the sliding groove 201, so that when the driving component 320 drives the probe 102 on the connecting component 310 to be stored in the storage tube 200, the probe 102 can be fixed by the clamping connection between the limiting groove 202 and the connecting block 321 to prevent the probe 102 from moving out of the tube cavity of the storage tube 200.

[0027] The storage device 300 includes a connecting component 310 for fixedly connecting to the imaging probe body 100, a driving component 320 for driving the imaging probe body 100 on the connecting component 310 to be stored in the storage tube 200 is provided on the side wall of the connecting component 310, and a connecting tube 330 for protecting the power cord of the imaging probe body 100 is provided at the bottom end of the connecting component 310.
