Fiber choledochoscope is mainly composed of fiber choledochoscope body and cold light source. The body is connected to the light source with the help of a connector, forming a set of fully functional fiber choledochoscope inspection and treatment system.

[0003] The choledochoscope uses optical fiber to collect and transmit images, and the end face of the optical fiber receives the image illuminated by a cold light source. During processing, the end face of the optical fiber needs to be polished to eliminate factors such as unevenness, cracks, contamination and oxidation on the end face, thereby improving the efficiency and quality of signal transmission.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0023] Choledochoscope, also known as bile duct endoscope, can enter the bile duct lumen for direct observation and operation, and is an important means of examination and treatment of biliary system diseases. Fiber choledochoscope is mainly composed of fiber choledochoscope body and cold light source. The body is connected to the light source with the help of a connector, forming a set of fully functional fiber choledochoscope inspection and treatment system.

[0024] The choledochoscope realizes image acquisition and transmission through optical fiber, and the end face of the optical fiber receives the image illuminated by the cold light source. During processing, the end face of the optical fiber needs to be polished to eliminate factors such as unevenness, cracks, contamination and oxidation of the end face, thereby improving the efficiency and quality of signal transmission. The present application provides a tooling device for polishing the end face of the optical fiber at the tail end of the choledochoscope to solve the problem of manual hand-held polishing in the current light end face polishing, limited accuracy and stability, and low work efficiency.

[0025] The specific structure of the tooling device for polishing the optical fiber end face at the tail end of a choledochoscope provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1 As shown, the present application provides a tooling device for polishing the end face of an optical fiber at the tail end of a choledochoscope, comprising a bracket 1, a choledochoscope fixing seat 2, an adjustment track seat 3 and a coupling tube clamping seat 4;

[0027] The two sides of the bracket 1 are symmetrically provided with slide rails 5, the slide rails 5 are slidably connected with sliders 51, the sliders 51 are fixedly connected with adapter plates 52 away from and parallel to the sides of the slide rails 5, and one end of the adapter plate 52 away from the slider 5 is fixedly connected to the choledochoscope fixing seat 2; the top of the slide rail 5 is provided with a spring fixing block 61, and a tension spring 6 is provided between the spring fixing block 61 and the adapter plate 52;

[0028] One end of the choledochoscope fixing seat 2 away from the bracket 1 is fixedly connected to the adjustment track seat 3, and the adjustment track seat 3 includes two symmetrically arranged adjustment plates 31, and the adjustment plates 31 are provided with adjustment tracks 32. Pins 41 are movably connected on both sides of the coupling tube clamping seat 4, and the pins 41 are clamped with the adjustment tracks 32; the pins 41 slide along the adjustment tracks 32 to achieve a 90° flip of the coupling tube clamping seat 4; the top surface of the coupling tube clamping seat 4 is provided with a first fixing groove 42 and a fixing clip 43, and the fixing clip 43 is rotatably connected to the coupling tube clamping seat 4 to fix the coupling tube at the tail end of the choledochoscope.

[0029] When in use, the tooling device provided in the embodiment of the present application is fixed on the workbench through the bracket 1, and the choledochoscope coupling tube is fixed on the coupling tube clamping seat 4 through the cooperation of the first fixing groove 42 and the fixing clamp 43, and is firmly fixed to avoid displacement or shaking of the coupling tube during the grinding process, thereby ensuring the quality and effect of grinding. The coupling tube clamping seat 4 is clamped by the pin 41 adjusting track 32, and the pin 41 cooperates with the adjusting track seat 3 to realize the 90° flipping of the coupling tube clamping seat 4. The adjusting track 32 provides a precise path for the flipping of the coupling tube clamping seat 4, ensuring the accuracy and stability of the flipping angle. After the coupling tube clamping seat 4 is flipped, the optical fiber end face in the coupling tube is vertically downward and connected to the grinding mechanism of the optical fiber grinder, which is convenient for grinding. The choledochoscope fixing seat 2 realizes vertical position adjustment by cooperating with the slide rails 5, the slider 51 and the adapter plate 52 symmetrically arranged on both sides, so that the optical fiber end face in the coupling tube at the tail end of the choledochoscope and the grinding mechanism of the optical fiber grinder maintain a reasonable pressure. Specifically, the spring fixing block 61 is fixed on the top of the slide rail 51, the spring fixing block 61 is connected to one end of the tension spring 6, the other end of the tension spring 6 is connected to the adapter plate 52, the slider 51, the adapter plate 52, the choledochoscope fixing seat 2, the adjustment track seat 3 and the coupling tube clamping seat 4 are connected together, and continuously pressed on the surface of the grinding mechanism of the optical fiber grinder under the action of gravity to achieve the grinding of the optical fiber end face, wherein the tension spring 6 provides a pulling force opposite to the direction of gravity to offset part of the gravity to ensure that the end face of the optical fiber tail is in sliding contact with the surface of the grinding mechanism to avoid the grinding mechanism from being stuck or the end face of the optical fiber tail being broken due to excessive gravity. The device achieves efficient and precise grinding of the optical fiber end face at the tail end of the choledochoscope by stably fixing the choledochoscope and accurately adjusting its position, thereby improving the grinding quality and ease of operation.

[0030] In some embodiments, a second fixing groove 21 is provided on the top surface of the choledochoscope fixing seat 2, and the second fixing groove 21 and the first fixing groove 42 are located in the same vertical plane. The second fixing groove 21 is used to fix the choledochoscope, and cooperates with the first fixing groove 42 to make the coupling tube more stable when fixed and not easy to shake, thereby improving the precision and safety of grinding.

[0031] Reference Figure 2 As shown, in some embodiments, a plurality of first threaded holes 54 are provided on the side of the slide rail 5, and a through hole 511 is provided on the side of the slider 51. Bolts pass through the through hole 511 and are threadedly connected with the first threaded hole 54 to fix the slider 51. This design allows the position of the slider 51 on the slide rail 5 to be accurately fixed, ensuring the stability of the choledochoscope during the grinding process and improving the grinding accuracy. It should be noted that when the slider 51 is fixed, the pressure between the end face of the optical fiber tail and the surface of the grinding mechanism should be within a reasonable range, otherwise, it does not need to be fixed, and it can be adjusted in real time by the tension spring during the grinding process.

[0032] Reference Figure 3 Shown and Figure 4 As shown, in some embodiments, a positioning block 62 and a locking screw 63 are also included; the positioning block 62 is fixedly connected to the adapter plate 52, the positioning block 62 is provided with a second positioning hole 621, the spring fixing block 61 is provided with a first positioning hole 611, and the locking screw 63 passes through the first positioning hole 611 and the second positioning hole 621 in sequence and is fixed in conjunction with the matching nut. The coordinated use of the positioning block 62 and the locking screw 63 further ensures the position stability of the choledochoscope fixing seat 2 on the slide rail 5, prevents its accidental movement during the grinding process, and improves the reliability of the grinding. It should be noted that when the position of the slider is locked, the pressure between the end face of the optical fiber tail and the surface of the grinding mechanism should be within a reasonable range, otherwise, it does not need to be fixed, and it can be adjusted in real time by the tension spring during the grinding process.

[0033] In some embodiments, a bracket fixing seat 11 is further included, and the bracket fixing seat 11 is fixedly connected to the bottom surface of the bracket 1, and the bracket 1 is provided with a plurality of second threaded holes 111. The design of the bracket fixing seat 11 enables the entire tooling device to be stably placed on the workbench, and the second threaded holes 111 allow the bracket 1 to be tightly fixed to the workbench by bolts, thereby improving the stability of the device.

[0034] In some embodiments, the end surface of the adjustment track seat 3 is a U-shaped structure, the bottom surface of the U-shaped structure is fixedly connected to the choledochoscope fixing seat 2, and the two parallel surfaces of the U-shaped structure are adjustment plates 31. Compared with separately setting two adjustment plates 31 to be connected to the choledochoscope fixing seat 2 respectively, the adjustment track seat 3 with a U-shaped structure makes the connection more secure.

[0035] In some embodiments, the slide rail 5 is provided with a plurality of third threaded holes 53 on the side perpendicular to the first threaded hole 54, and the plurality of third threaded holes 53 are arranged vertically and equidistantly from top to bottom; the spring fixing block 61 is provided with a mounting hole 612, and the bolt passes through the mounting hole 612 and is threadedly connected with the third threaded hole 53. The third threaded hole 53 cooperates with the mounting hole 612 to adjust the position of the spring fixing block 61, thereby adjusting the tension of the tension spring 6 on the choledochoscope fixing seat 2, the adjusting rail seat 3, the coupling tube clamping seat 4 and other components, further ensuring the reasonable contact between the end face of the optical fiber tail and the surface of the grinding structure of the optical fiber grinder, and ensuring the grinding quality.

[0036] According to the above technical features, the method of using the tooling device for polishing the end face of the optical fiber at the tail end of the choledochoscope provided by the present application in an actual application scenario is:

[0037] When in use, one end of the choledochoscope is manually placed into the second fixing groove 21 on the top surface of the choledochoscope fixing seat 2, the choledochoscope coupling tube is placed in the first fixing groove 42 of the coupling tube clamping seat 4, the fixing clamp 43 is opened to fix the coupling tube, and the coupling tube clamping seat 4 is pushed to move along the adjustment track 32 on the adjustment track seat 3, so that it slides from one end of the adjustment track 32 to the other end. At this time, the coupling tube clamping seat 4 is 90° with the choledochoscope body. At this time, the tail end face of the optical fiber is vertically downward, and due to the gravity of the choledochoscope fixing seat 2, the adjustment track seat 3 and the coupling tube clamping seat 4, the tail end face of the optical fiber is continuously pressed on the grinding surface of the optical fiber grinder, and the tension spring 6 provides an upward pulling force, so that the pressure between the tail end face of the optical fiber and the grinding surface is within a reasonable range, thereby ensuring the grinding quality of the tail end face of the optical fiber.

[0038] In summary, the tooling device provided by the present application realizes efficient and precise grinding of the optical fiber end face at the tail end of the choledochoscope, improves the grinding quality and operation convenience, and provides strong support for the maintenance and repair of the choledochoscope. It solves the problem that the current manual hand-held grinding of the optical fiber end face of the choledochoscope leads to low work efficiency and unreliable quality.
