[0002] Optical coherence tomography (OCT) is an imaging technology that has developed rapidly in the past decade. It uses the basic principle of a weak coherent light interferometer to detect the backscattering signals of different depth layers of biological tissues. Through scanning, two-dimensional or three-dimensional structure images of biological tissues can be obtained.

[0003] As shown in the prior art, the catheter loading system in the intravascular optical coherence tomography diagnosis system includes a walking motor 1', a rotating motor 2', and a sliding group. The output end of the rotating motor 2' is provided with a fiber adapter 3', and the rotating motor 2' is arranged at the moving end of the sliding group. The walking motor 1' can drive the rotating motor 2' to move the fiber adapter 3' towards the fiber connector 4' and make the fiber connector 4' be inserted into the fiber adapter 3'. Figure 1 The working process is as follows: the walking motor 1' drives the rotating motor 2' to move, and at the same time, the rotating motor 2' drives the fiber adapter 3' to rotate. Through the cooperation of the walking motor 1' and the rotating motor 2', the fiber adapter 3' and the fiber connector 4' are inserted. This structure realizes the mutual insertion of the fiber connector 4' and the fiber adapter 3' through the cooperation of the walking motor 1' and the rotating motor 2'. However, the mechanical structure and electrical control of this structure are relatively complex, especially the requirement for electrical control is high, and the failure rate is high during use.

[0045] The OCT imaging device inserts the catheter 100 from the human body blood vessel to the coronary artery of the heart, and the end of the catheter 100 is provided with a lens. The high-speed rotation of the catheter 100 drives the lens to rotate to make the lens shoot the inside of the blood vessel, so as to understand whether there is an abnormality in the blood vessel.

[0046] As Figures 2-10As shown, the OCT catheter loading system comprises a catheter device 1, a driving device 2 and a mounting plate 3. Among them, the catheter device 1 comprises a first plug-in assembly 11, a fixing sleeve 12 and a fiber connector 13, the fixing sleeve 12 is arranged in the first plug-in assembly 11, and the fixing sleeve 12 can move in the first plug-in assembly 11, the fixing sleeve 12 has an initial position and a rotating position relative to the first plug-in assembly 11, when the first plug-in assembly 11 is located at the initial position of the fixing sleeve 12, the fixing sleeve 12 cannot rotate relative to the first plug-in assembly 11, and when the first plug-in assembly 11 is located at the rotating position of the fixing sleeve 12, the fixing sleeve 12 can rotate relative to the first plug-in assembly 11; the fiber connector 13 is fixedly arranged in the fixing sleeve 12, and the catheter 100 is plugged into the fiber connector 13. The driving device 2 comprises a fixed seat 21, a second plug-in assembly 22, a fiber adapter 23 and a driving assembly 24, the fixed seat 21 is fixedly arranged on the mounting plate 3, the second plug-in assembly 22 is arranged on the fixed seat 21, the fiber adapter 23 is arranged in the fixed seat 21 through a fixing piece 25, the output end of the driving assembly 24 is fixedly connected with the fixing piece 25, and the fixing piece 25 can be driven to rotate relative to the fixed seat 21; when the catheter device 1 and the driving device 2 are loaded, after the fiber connector 13 is plugged into the fiber adapter 23 to the position, the second plug-in assembly 22 can push the first plug-in assembly 11 to move from the initial position to the rotating position relative to the fixing sleeve 12, the driving assembly 24 drives the fixing piece 25 to drive the fiber adapter 23 to rotate, so that the fiber connector 13 drives the catheter 100 to rotate.

[0047] The fiber connector 3' in the prior art can rotate before and after loading, so when the fiber connector 3' is plugged into the fiber adapter 3', the rotating motor 2' and the walking motor 1' need to be matched to make the fiber adapter 3' plug into the fiber connector 4' in rotation.

[0048] Before the catheter device 1 and the driving device 2 are loaded, the first plug-in assembly 11 is located at the initial position of the fixing sleeve 12, the fixing sleeve 12 does not rotate relative to the first plug-in assembly 11, that is, the position of the fiber connector 13 is fixed, when the catheter device 1 and the driving device 2 are loaded, the driving assembly 24 stops rotating, the fiber connector 13 and the fiber adapter 23 are aligned and plugged into each other, after the fiber connector 13 is plugged into the fiber adapter 23 to the position, the second plug-in assembly 22 pushes the first plug-in assembly 11 to move from the initial position to the rotating position relative to the fixing sleeve 12, so that the driving assembly 24 drives the fiber adapter 23 to rotate, and then the fiber connector 13 drives the catheter 100 to rotate, so that the plugging work of the fiber connector 13 and the fiber adapter 23 can be completed manually, the structure design is ingenious, the use is convenient, and the failure rate is reduced.

[0049] Specifically, refer to Figures 3-4The first plug-in assembly 11 comprises a plug-in handle 111 and a plug-in end sleeve 112, the plug-in handle 111 is fixedly connected with the plug-in end sleeve 112, the plug-in end sleeve 112 is provided with a through cavity, the fixing sleeve 12 is movably arranged in the through cavity, the fixing sleeve 12 has an initial position and a rotating position relative to the plug-in end sleeve 112, and the second plug-in assembly 22 can push the plug-in end sleeve 112 to move from the initial position to the rotating position relative to the fixing sleeve 12. The plug-in handle 111 is arranged to make the operation more convenient.

[0050] In the embodiment, the plug-in handle 111 is inserted into the through cavity of the plug-in end sleeve 112, the insertion end of the plug-in handle 111 is a circular ring structure, and the outer wall of the insertion end is provided with a barb 1111, the two sides of the barb 1111 are provided with cutouts to facilitate deformation when the barb 1111 is extruded, the plug-in end sleeve 112 is provided with a first through hole 1125 on the inner wall of the through cavity, when the insertion end is inserted into the through cavity, the inner wall of the through cavity extrudes the barb 1111, when the barb 1111 is opposite to the first through hole 1125, the barb 1111 is reset and clamped into the first through hole 1125, so that the plug-in handle 111 is clamped with the plug-in end sleeve 112. The barb 1111 and the first through hole 1125 are arranged one by one, and two barbs 1111 are arranged respectively in two first through holes 1125 to make the structure more stable.

[0051] In order to make the plug-in handle 111 and the plug-in end sleeve 112 more convenient when being plugged in, the plug-in end sleeve 112 is provided with a first ear-shaped part 1127, the first ear-shaped part 1127 is provided with a limiting groove, the plug-in handle 111 is provided with a second ear-shaped part 1113 matched with the limiting groove, when the second ear-shaped part 1113 is embedded in the limiting groove when the plug-in handle 111 and the plug-in end sleeve 112 are plugged in, the barb 1111 can be clamped in the first through hole 1125.

[0052] More specifically, the plug-in end sleeve 112 is provided with a first limiting strip 1121 on the inner wall of the through cavity along the axis direction of the through cavity, the fixing sleeve 12 is provided with a first outer ring table 121 close to one end of the fiber connector 13, the first outer ring table 121 is provided with a notch 1211, and the first limiting strip 1121 can be embedded in the notch 1211. When the fixing sleeve 12 is installed in the through cavity, the plug-in end sleeve 112 is located at the initial position relative to the fixing sleeve 12, the first limiting strip 1121 is limited in the notch 1211; when the plug-in end sleeve 112 moves to the rotating position relative to the fixing sleeve 12, the plug-in end sleeve 112 moves relative to the fixing sleeve 12 to make the first limiting strip 1121 move out of the notch 1211, that is, the first outer ring table 121 does not interfere with the first limiting strip 1121 when the fixing sleeve 12 rotates relative to the plug-in end sleeve 112.

[0053] In order to guide the insertion of the fixing sleeve 12 into the through cavity, a second limiting strip 1122 is arranged on the inner wall of the through cavity, and the second limiting strip 1122 is arranged side by side and spaced apart from the first limiting strip 1121. When the fixing sleeve 12 is installed in the through cavity, the notch 1211 of the first outer ring table 121 is first limited to the second limiting strip 1122, and the fixing sleeve 12 is pushed to slide along the guiding direction of the second limiting strip 1122, so as to ensure the accurate position of the fixing sleeve 12 and the plug-in end sleeve 112. When the plug-in end sleeve 112 moves to the rotating position relative to the fixing sleeve 12, the first outer ring table 121 is located between the first limiting strip 1121 and the second limiting strip 1122.

[0054] In order to facilitate the limiting of the fixing sleeve 12 and the plug-in end sleeve 112, the plug-in end sleeve 112 is provided with an inner ring table 1123 on the inner wall of the through cavity. When the plug-in end sleeve 112 is located at the initial position relative to the fixing sleeve 12, the first outer ring table 121 abuts against the inner ring table 1123. This structure can realize the initial position limitation of the fixing sleeve 12 and the plug-in end sleeve 112 when the fixing sleeve 12 is inserted into the through cavity until the first outer ring table 121 abuts against the inner ring table 1123.

[0055] The other end of the fixing sleeve 12 away from the first outer ring table 121 is provided with a second outer ring table 122. When the catheter device 1 is unloaded from the driving device 2, the plug-in handle 111 is pulled to drive the plug-in end sleeve 112 to move. When the second outer ring table abuts against the plug-in handle 111, the plug-in handle 111 is continuously pulled to drive the plug-in handle 111 to move away from the driving device 2, so that the optical fiber connector 13 is separated from the optical fiber adapter 23.

[0056] Specifically, the plug-in handle 111 is provided with a sliding cavity 1112, and the opposite sides of the second outer ring table 122 are provided as parallel planes, forming a long strip-shaped second outer ring table 122. The port of the sliding cavity 1112 is provided with a long strip-shaped opening matched with the long strip-shaped second outer ring table 122. After the second outer ring table 122 enters the sliding cavity 1112 through the long strip-shaped opening and rotates, the second outer ring table 122 can be clamped with the long strip-shaped opening.

[0057] Referring to Figures 5-6, the second plug-in assembly 22 comprises a plug-in seat 221, a sliding sleeve 222, a compression spring 223 and a fixed end sleeve 224, the plug-in seat 221 is fixedly arranged on the fixed seat 21, the plug-in seat 221 is provided with a stepped through groove, the sliding sleeve 222 is slidingly arranged in the stepped through groove, the fixed end sleeve 224 is fixedly arranged on the plug-in seat 221, the compression spring 223 is sleeved on the sliding sleeve 222 and abuts against the sliding sleeve 222 and the fixed end sleeve 224 respectively, and the sliding sleeve 222 abuts against the stepped surface of the stepped through groove under the action force of the compression spring 223. When the catheter device 1 is loaded with the driving device 2, the plug-in handle 111 is manually pushed to make the plug-in end sleeve 112 abut against the sliding sleeve 222 and move away from the plug-in end sleeve 112 against the action force of the compression spring 223, when the optical fiber connector 13 and the optical fiber adapter 23 are plugged into place, the plug-in handle 111 is released, the sliding sleeve 222 pushes the plug-in end sleeve 112 to move backward under the action force of the compression spring 223, at this time, the optical fiber connector 13 and the optical fiber adapter 23 have been plugged and locked, therefore, the fixed sleeve 12 will not move, the sliding sleeve 222 pushes the plug-in end sleeve 112 to move to a rotating position relative to the fixed sleeve 12 and abut against the stepped surface. The structure realizes that the sliding sleeve 222 automatically pushes the plug-in end sleeve 112 to move relative to the fixed sleeve 12 after the optical fiber connector 13 and the optical fiber adapter 23 are plugged into place, and the structure is simple and convenient to use.

[0058] In order to enable the plug-in end sleeve 112 to not move in the axial direction thereof without manual external force, the plug-in end sleeve 112 is provided with a second through hole 1126 on the inner wall of the through cavity, and the plug-in seat 221 is provided with a clamping piece 225, when the plug-in end sleeve 112 is located at the rotating position relative to the fixed sleeve 12, the clamping piece 225 can be clamped in the second through hole 1126 to prevent the plug-in end sleeve 112 from moving when the fixed seat 21 rotates. Referring to Figures 4-5 The clamping piece 225 comprises a rotating rod, a rotating shaft and a spring, the rotating shaft is arranged on the plug-in seat 221, the rotating rod is rotationally arranged on the rotating shaft, the spring is clamped between the upper end of the rotating rod and the top end of the plug-in seat 221, and the lower end of the rotating rod can protrude into the stepped through groove under the action force of the spring, when the plug-in end sleeve 112 is inserted into the stepped through groove and the plug-in end sleeve 112 is located at the rotating position relative to the fixed sleeve 12 under the pushing of the sliding sleeve 222, the lower end of the rotating rod is inserted into the second through hole 1126 to prevent the plug-in end sleeve 112 from continuing to displace. In the embodiment, the clamping piece 225 and the second through hole 1126 are arranged one by one, and both are provided with two, the two clamping pieces 225 are clamped into the two second through holes 1126 respectively to make the structure more stable.

[0059] Now, the application will be further described in combination with Figures 7-9Detailed description of the loading process: when the catheter device 1 is loaded with the driving device 2, the plug handle 111 is held and pushed towards the fiber adapter 23, driving the fiber connector 13 to insert into the fiber adapter 23 but not plugged in place, the plug end sleeve 112 is in the initial position relative to the fixed sleeve 12, the sliding sleeve 222 abuts the stepped surface, refer to Figure 7 ; continue to push the plug handle 111 to make the fiber connector 13 fully inserted into the fiber adapter 23, the sliding sleeve 222 moves away from the stepped surface under the action of the plug end sleeve 112, refer to Figure 8 ; release the plug handle 111, the sliding sleeve 222 moves towards the stepped surface under the action of the compression spring 223 and pushes the plug end sleeve 112 to move relative to the fixed sleeve 12 to the rotating position, refer to Figure 9 ; the loading is completed.

[0060] The sliding sleeve 222 is provided with a limiting portion 2221, and the fixed end sleeve 224 is provided with a limiting sliding groove 2241, and the limiting portion 2221 is slidingly arranged in the limiting sliding groove 2241. This structure can prevent the sliding sleeve 222 from rotating, and the structure is more reasonable. Refer to Figure 6 , the limiting portion 2221 is provided with two limiting portions 2221, which are evenly distributed on the end of the sliding sleeve 222, and the limiting sliding groove 2241 is provided with two limiting sliding grooves 2241 which are evenly distributed on the inner side wall of the fixed end sleeve 224, and the two limiting portions 2221 are inserted into the two limiting sliding grooves 2241 respectively, so that the structure is more stable.

[0061] The first ear-shaped portion 1127 of the plug end sleeve 112 is provided with a plug boss 1124, and the plug seat 221 is provided with a plug groove 2211, and when the fiber connector 13 is plugged into the fiber adapter 23, the plug boss 1124 is plugged into the plug groove 2211. This structure can prevent the plug end sleeve 112 from rotating when the fixed sleeve 12 rotates, and can ensure the accurate plugging position of the fiber connector 13 and the fiber adapter 23. It can be understood that when the plug end sleeve 112 is in the initial position relative to the fixed sleeve 12, the position of the fiber connector 13 is fixed and unique, and the position of the output end of the driving assembly 24 is set to be the same each time the driving assembly 24 stops, so that the stopping position of the fiber adapter 23 is the same, therefore, when the fiber connector 13 is plugged into the fiber adapter 23, as long as the plug boss 1124 and the plug groove 2211 are opposite, the fiber connector 13 can be inserted into the fiber adapter 23.
