Abstract
Description
Technical Field
[0001] The present disclosure relates to medical devices, and particularly to a controllable bending optical fiber structure and a laser treatment system. Background Art
[0002] Ureteroscopic lithotripsy treats upper urinary tract stones through the natural urinary cavity of the human body, with the characteristics of minimally invasive, safe and effective. It has become the preferred treatment method for kidney stones with a diameter of less than 2 cm. At the same time, it is paired with a laser energy platform and has become a sharp tool and treatment "gold standard" for ureteroscopic lithotripsy. Subdivided from the design and application characteristics: rigid ureteroscopes are suitable for treating middle and lower ureteral stones; flexible ureteroscopes are more suitable for treating upper ureteral and kidney stones.
[0003] During ureteral laser lithotripsy surgery, the current minimum size that a flexible ureteroscope can achieve is 9.6 Fr. Therefore, the situation where the operation fails due to the flexible ureteroscope being unable to pass through the three narrow segments of the ureter to reach the stone site occurs from time to time. The existing traditional technology is to use a guide wire, an auxiliary catheter or a dilator to assist in passing through the narrow segment.
[0004] However, each of the above three has its own disadvantages: the outer diameter difference between the guide wire and the visible catheter or ureteroscope is too large, and the actual surgical success rate is low; the end face of the auxiliary catheter is relatively hard, which is likely to cause secondary ureteral injury; the cost of an independent dilator is relatively high, the operation is complex, and the dilator passing through the inner cavity of the visible catheter or ureteroscope may further increase its overall diameter.

Detailed implementation manners
[0030] It should be understood that the exemplary embodiments described herein should be considered only as descriptive and not for the purpose of limitation. The description of the features or aspects in each exemplary embodiment should generally be considered applicable to similar features or aspects in other exemplary embodiments.
[0031] In the prior art, the flexible ureteroscopes prepared are all equipped with snake bones or similar structures, which will greatly increase the manufacturing difficulty and production cost. Therefore, the present disclosure provides a controllable bending optical fiber structure to solve the above problems.
[0032] Specifically, as Figures 1-4 shown, the present disclosure provides a controllable bending optical fiber structure, including: a laser optical fiber 110, a traction wire, a first sensor wire harness 120, a lens assembly 150, and a sleeve assembly. The sleeve assembly is sleeved outside the laser optical fiber 110, the traction wire, and the first sensor wire harness 120, and the lens assembly 150 is arranged at the front end of the sleeve assembly and is connected to the first sensor wire harness 120, wherein the traction wire is used to drive the sleeve assembly to bend so as to drive the laser optical fiber 110 to bend.
[0033] For easy understanding, the present disclosure marks the first direction M in Figure 1 and Figure 3 , and the first direction M is the direction from the back to the front.
[0034] It should be noted that the sleeve assembly can be a single-layer sleeve or a multi-layer sleeve. In some embodiments, the sleeve assembly includes a sleeve body and a helical tube, and the mounting member is a rigid structure, wherein the sleeve body is a flexible structure. Specifically, the sleeve body includes a first sleeve 140 and a second sleeve 160, and the first sleeve 140 and the second sleeve 160 are flexible structures and can be bent under the action of the traction wire.
[0035] The controllable-bending optical fiber structure of the present disclosure does not adopt a snake bone or a similar structure. Only the sleeve assembly is sleeved outside the laser optical fiber 110, the traction wire, and the first sensor wire harness 120 to protect the laser optical fiber 110, the traction wire, and the first sensor wire harness 120, so that the production cost of the controllable-bending optical fiber structure of the present disclosure is reduced and its size is small. More specifically, the outer diameter of the sleeve assembly is 2-3.2 mm.
[0036] Optionally, as Figure 2 , Figure 5 and Figure 6 shown, the controllable-bending optical fiber structure includes a first traction wire 131 and a second traction wire 132. The front end of the first traction wire 131 is connected to one side of the front end of the sleeve assembly, and the front end of the second traction wire 132 is connected to the other side of the front end of the sleeve assembly. In addition, the controllable-bending optical fiber structure further includes a third traction wire 133 and a fourth traction wire 134. The front end of the third traction wire 133 is connected to the upper side of the front end of the sleeve assembly, and the front end of the fourth traction wire 134 is connected to the lower side of the front end of the sleeve assembly, wherein the front end of the first traction wire 131 is connected to the left side of the front end of the sleeve assembly, and the front end of the second traction wire 132 is connected to the right side of the front end of the sleeve assembly.
[0037] In some alternative embodiments, the bendable optical fiber structure includes a first rotating member and a second rotating member. By rotating the first rotating member to pull or relax the first traction wire 131 and the second traction wire 132, the bendable optical fiber structure is driven to bend left or right; by rotating the second rotating member to pull or relax the third traction wire 133 and the fourth traction wire 134, the bendable optical fiber structure is driven to bend up or down. More specifically, the bendable optical fiber structure further includes a handle 200. The handle 200 includes a housing 210 and a bending adjustment assembly 220. The bending adjustment assembly 220 is disposed on the housing 210 and the bending adjustment assembly 220 includes a first swing arm knob 230, a second swing arm knob 240 and a knob box 250. The first rotating member 260 and the second rotating member are disposed in the rotating box. The first rotating member 260 is connected to the first swing arm knob 230, and the second rotating member is connected to the second swing arm knob 240. The traction wires include a first traction wire 131, a second traction wire 132, a third traction wire 133 and a fourth traction wire 134. The rear ends of the first traction wire 131 and the second traction wire 132 are connected to both sides of the first rotating member 260, and the front ends of the first traction wire 131 and the second traction wire 132 are respectively fixed to the left and right sides of the first sleeve 140. Therefore, after the first swing arm knob 230 rotates, it can drive the first rotating member 260 to rotate and drive one of the first traction wire 131 and the second traction wire 132 to relax, and the other to tighten, thereby driving the front end of the first sleeve 140 to bend left or right, and further driving the laser optical fiber 110 to bend and the orientation of the lens assembly 150 to change. Similarly, the rear ends of the third traction wire 133 and the fourth traction wire 134 are connected to both sides of the second rotating member, and the front ends of the third traction wire 133 and the fourth traction wire 134 are respectively fixed to the upper and lower sides of the first sleeve 140. Therefore, after the second swing arm knob 240 rotates, it can drive the second rotating member to rotate and drive one of the third traction wire 133 and the fourth traction wire 134 to relax, and the other to tighten, thereby driving the rear end of the first sleeve 140 to bend up or down.
[0038] In addition, as Figure 7As shown, the housing 210 is formed with an inlet 211 and a wire harness outlet 212. Among them, the inlet of the housing 210 is for the rear end of the steerable optical fiber structure to enter therein, and the wire harness outlet is mainly for the illumination optical fiber 190, the first sensor wire harness 120, and the second sensor wire harness 170 to come out of the housing 210. After the illumination optical fiber 190 comes out of the wire harness outlet, it will be connected to a light source to provide illumination for the steerable optical fiber structure. After the first sensor wire harness 120 comes out of the wire harness outlet, it will be connected to an image processor. The image information collected by the lens 151 on the lens assembly 150 is transmitted to the image processor through the first sensor wire harness, and after being processed by the image processor, it is presented on the display screen. After the second sensor wire harness 170 comes out of the wire harness outlet, it is connected to the control component 380 to transmit the temperature information and pressure information obtained by the temperature and pressure sensor 152 to the control component.
[0039] Meanwhile, the housing 210 is formed with an optical fiber outlet, and the rear end of the laser optical fiber 110 can come out of the optical fiber outlet to be connected to a laser treatment machine. The laser emitted by the laser treatment machine can reach the front of the steerable optical fiber structure through the laser optical fiber 110 and crush the stone located in front of the steerable optical fiber.
[0040] In order to facilitate the delivery of the perfusion fluid into the infusion tube 180 of the patient to reduce the temperature of the tissue near the laser treatment site and clean the lens 151, in some alternative embodiments, the steerable optical fiber structure includes an infusion tube 180 that penetrates the sleeve assembly, and the perfusion fluid can flow out of the infusion tube 180.
[0041] Optionally, the steerable optical fiber structure includes a temperature and pressure sensor 152. The temperature and pressure sensor 152 is located at the front end of the sleeve assembly, and the second sensor wire harness penetrates the sleeve assembly back and forth to be connected to the temperature and pressure sensor 152.
[0042] Optionally, the lens assembly 150 includes a lens 151 and a mounting member 153. The lens 151 is mounted on the mounting member 153 and is located on the front end face 1531 of the mounting member. The temperature and pressure sensor 152 is located on the side face 1532 of the mounting member. The mounting member 153 is mounted in front of the sleeve assembly.
[0043] More specifically, the laser optical fiber 110 penetrates the sleeve assembly and extends in front of the mounting member 153 to better emit the laser. In addition, the water delivery pipe also penetrates the mounting member 153, so that the perfusion fluid is ejected from the front end of the steerable optical fiber structure.
[0044] In addition, the present disclosure also provides a laser treatment system, including a laser treatment machine and a controllable bending optical fiber structure. The laser treatment machine is connected to a laser optical fiber 110 to provide laser for the laser optical fiber 110. When crushing a ureteral calculus, the laser treatment machine can be connected to the laser optical fiber 110, and then the laser treatment machine is started to emit laser, and the laser reaches the surface of the calculus through the laser optical fiber 110 to crush the calculus.
[0045] Optionally, the controllable bending optical fiber structure can be used in combination with an outer sheath tube 400. Specifically, the outer sheath tube 400 is sleeved on the middle part of the controllable bending optical fiber structure, and the outer sheath tube 400 is formed with an outer sheath tube channel 410. As Figure 8 shown, the outer sheath tube channel 410 is formed with a first opening 420, a second opening 430 and a third opening 440. The first opening 420 is located at the front end of the outer sheath tube 400, the second opening 430 is located at the rear end of the outer sheath tube 400, and the controllable bending optical fiber structure enters from the second opening 430 and passes through the outer sheath tube channel 410, and finally extends out from the first opening 420.
[0046] In addition, there is a gap between the controllable bending optical fiber structure and the outer sheath tube channel 410 to form a suction channel, and the suction channel can be connected to a suction assembly to suck out the perfusion fluid in the patient's body. Specifically, the suction channel communicates with the third opening 440, and the suction assembly can be placed at the third opening 440.
[0047] When using the controllable bending optical fiber structure of the present disclosure, first, a light source is connected to an illumination optical fiber 190 to facilitate illuminating the internal structure of the body. Secondly, the front end of the controllable bending optical fiber structure can be gradually inserted into the patient's body, and after passing through the bladder, it reaches the patient's ureter. The position of the calculus in the ureter is observed through a lens 151 on a lens assembly 150, and the front end of a first sleeve 140 is bent by operating a handle 200, thereby driving the front end of a laser optical fiber 110 located in the first sleeve 140 to bend. At this time, the sleeve assembly, an infusion tube 180 and the illumination optical fiber 190 will also bend. Then, perfusion fluid is input into the infusion tube 180, so that the perfusion fluid is transported to the lesion area while cleaning the lens 151 at the front end of the controllable bending optical fiber structure. At the same time, the laser treatment machine is started, and the laser is emitted from the laser treatment machine and shoots along the laser optical fiber 110 to the calculus to crush the calculus. The crushed calculus gradually flows out from the bladder through the backflow of the perfusion fluid (at this time, the outer sheath tube 400 should be present in the patient's body to facilitate the backflow of the perfusion fluid).
[0048] Among them, the perfusion fluid generally refers to the liquid injected in medical surgeries or scientific research experiments to maintain the activity, cleanliness of organs, tissues or cells, or for specific treatment purposes. In the present disclosure, the perfusion fluid can be physiological saline, glucose solution or mannitol solution, which is mainly used to flush and clean the surgical area to make the surgical field clear, prevent thermal damage caused by laser, and the small particles after lithotripsy can be assisted to be discharged out of the body through the flow of physiological saline.
[0049] The present disclosure provides a method for preparing a controllable bending optical fiber structure, as Figure 10 shown, including:
[0050] Step S100: Draw a laser optical fiber and move the laser optical fiber;
[0051] Step S200: Move the first sensor wire harness and the traction wire so that the first sensor wire harness, the traction wire and the laser optical fiber move together;
[0052] Step S300: During the process of the first sensor wire harness, the traction wire and the laser optical fiber moving together, sleuth a first sleeve outside the first sensor wire harness, the traction wire and the laser optical fiber to form an inner layer part.
[0053] Step S400: Set a lens assembly in front of the first sleeve during the movement of the inner layer part, wherein the lens assembly is connected to the first sensor wire harness.
[0054] Step S500: During the process of the inner layer part and the lens assembly moving together, sleuth a second sleeve outside the inner layer part and the lens assembly.
[0055] Step S600: Monitor the positions of the first sensor wire harness, the traction wire and the laser optical fiber to control the positions of the wire harness, the traction wire and the laser optical fiber to be arranged according to a preset position during the process of moving together.
[0056] First of all, the inner layer part includes a first sleeve 140, a first sensor wire harness 120, a traction wire and a laser optical fiber 110. The material of the first sleeve 140 is a polymer material with a small friction coefficient, such as commonly used polytetrafluoroethylene, etc. The first sensor wire harness 120 is used to connect with a sensor to transmit signals for the sensor. The traction wire is used to guide the bending of the controllable bending optical fiber structure. Specifically, the controllable bending optical fiber structure includes at least two traction wires, and the two traction wires are respectively located on both sides. By pulling the traction wire on one side to relax the traction wire on the other side, the purpose of bending the controllable bending optical fiber structure is achieved. The laser optical fiber 110 is used to connect with a device that emits laser to emit laser.
[0057] The above solution forms a first sleeve 140 outside the first sensor harness 120, the traction wire and the laser optical fiber 110 by extrusion to protect the first sensor harness 120, the traction wire and the laser optical fiber 110 from being damaged. For details, please refer to Figure 5 .
[0058] In addition, during the manufacturing process, the laser optical fiber 110 is drawn by an optical fiber machine, and the laser optical fiber 110 is clamped and conveyed by at least two conveyor belts. At the same time, the traction wire and the first sensor harness 120 are clamped and conveyed by other conveyor belts, and it is ensured that the moving speed of the laser optical fiber 110 is the same as that of the traction wire and the first sensor harness 120, and the traction wire, the first sensor harness 120 and the laser optical fiber 110 remain parallel to each other during the movement. It should be noted that the position of the laser optical fiber 110 may be different from that of the traction wire and the first sensor harness 120. For example, the front end of the laser optical fiber 110 is located about 10 cm in front of the traction wire and the first sensor harness 120.
[0059] Secondly, as Figure 11 shown, the preparation method of the present disclosure further includes step S610 and step S620. Among them, in step 610, before the first sleeve 140 is sleeved outside the traction wire, the first sensor harness 120 and the laser optical fiber 110, the monitoring device 370 (such as an infrared device) can be used to monitor whether the positions of the traction wire, the first sensor harness 120 and the laser optical fiber 110 are arranged according to the preset positions. For example, the traction wire and the first sensor harness 120 move side by side, and the front end of the laser optical fiber 110 is 10 cm in front of the traction wire and the first sensor harness 120. Once it is found that the positions of the traction wire, the first sensor harness 120 and the laser optical fiber 110 are not arranged according to the preset positions, the moving speed of the conveyor belt 320 can be adjusted so that the three are arranged according to the preset positions.
[0060] Step S620 is that after the first sleeve 140 is sleeved on the traction wire, the first sensor harness 120 and the laser optical fiber 110, the monitoring device 370 (such as an infrared device) can also be used to monitor the positions of the traction wire, the first sensor harness 120 and the laser optical fiber 110.
[0061] Specifically, multiple infrared devices can emit multiple infrared rays that form a horizontal and vertical cross-shaped network. According to the triggered infrared rays, the horizontal and vertical coordinates of the triggered position can be obtained to confirm the items passing through (such as the traction wire, the first sensor harness 120 and the laser optical fiber 110). Then, the infrared device is connected to the control device, and the time difference of the item passing through can be analyzed, and then the distance difference of the item can be inferred.
[0062] After setting the first sleeve 140, etc., a lens assembly 150 can be provided in front of the inner layer portion. Specifically, the first sleeve 140 is connected to the traction wire, the first sensor wire harness 120, and the laser optical fiber 110, and the front end of the laser optical fiber 110 is located in front of the first sleeve 140, the traction wire, and the first sensor wire harness 120. Therefore, driving the laser optical fiber 110 by the robotic arm 330 can drive the first sleeve 140, the traction wire, and the first sensor wire harness 120, causing the entire inner layer structure to move forward. During the forward movement of the entire inner layer structure, the lens assembly 150 is assembled by the robotic arm 330 and the dispensing machine 340, so that the lens assembly 150 is located in front of the first sleeve 140 and the wire harness interface of the first sensor wire harness 120 is connected to the lens assembly 150. Therefore, the information obtained by the lens assembly 150 will be transmitted to the outside through the first sensor wire harness 120. It should be noted that the laser optical fiber needs to protrude forward from the lens assembly 150 to facilitate the emission of laser light.
[0063] Next, during the movement of the inner layer portion together with the lens assembly 150, the second sleeve 160 is sleeved outside the inner layer portion and the lens assembly 150. It should be noted that the installation method of the second sleeve 160 will be described in the subsequent specification.
[0064] In some alternative embodiments, during the movement of the first sensor wire harness 120, the traction wire, and the laser optical fiber 110 together, extrusion molding is performed to sleeve the first sleeve 140 generated by extrusion molding outside the first sensor wire harness 120, the traction wire, and the laser optical fiber 110; the extrusion speed is adjusted according to the moving speed of the first sensor wire harness 120, the traction wire, and the laser optical fiber 110 to ensure that the extrusion speed of the plastic is consistent with the moving speed of the first sensor wire harness 120, the traction wire, and the laser optical fiber 110.
[0065] Specifically, an existing extrusion molding device for tetrafluoroethylene can be used to form the first sleeve 140 outside the first sensor wire harness 120, the traction wire, and the laser optical fiber 110. However, the extrusion speed of the extrusion molding device needs to be controlled so that the extrusion speed of the plastic is consistent with the moving speed of the first sensor wire harness 120, the traction wire, and the laser optical fiber 110. More specifically, the laser optical fiber 110 can be first inserted into the extrusion molding device for a certain distance, and then extrusion molding can be started so that the front end of the laser optical fiber 110 is located in front of the first sleeve 140. After extrusion molding, it will wrap the laser optical fiber 110, the first sensor wire harness 120, and the traction wire.
[0066] It should be noted that the extrusion molding device is signal-connected to the control component 380, and the extrusion molding device is controlled by the control component 380. Of course, in some embodiments, the extrusion molding device itself may have a control structure to control the extrusion speed of its own extrusion molding device. The extrusion molding device may be an extruder. For example, in some embodiments, the first sleeve 140 is formed by the first extruder 350, and the second sleeve 160 is formed by the second extruder 360.
[0067] In some other alternative embodiments, instead of forming the first sleeve 140 by extrusion, the first sensor harness 120, the traction wire, and the laser optical fiber 110 are bonded together during the process of moving together, and the first sleeve 140 is sleeved outside the first sensor harness 120, the traction wire, and the laser optical fiber 110. Specifically, first, the first sensor harness 120, the traction wire, and the laser optical fiber 110 are connected together by the robotic arm 330 and the dispensing machine 340, and then the combination of the first sensor harness 120, the traction wire, and the laser optical fiber 110 coated with glue on the outside is inserted into the first sleeve 140 to form a bond with the first sleeve 140.
[0068] After the installation of the lens assembly 150 is completed, the second sleeve 160 can be sleeved on the inner layer structure to wrap the inner layer structure.
[0069] In addition, in steps S100 to S600, the first sensor harness, the traction wire, and the laser optical fiber are always moving, and the drawing of the laser optical fiber is maintained during the movement of the laser optical fiber. The purpose of this setting is to ensure the coherence between each step. For example, when the drawing of the laser optical fiber is completed, it will be sent into the first extruder together with the first sensor harness and the traction wire for extrusion to form the first sleeve on its outer side. Moreover, when the laser optical fiber is gradually sent into the first extruder, the subsequent laser optical fiber is also continuously drawn out to ensure that the laser optical fiber is continuous throughout the production.
[0070] Optionally, it includes step S110 of moving the second sensor wire harness 170 so that the first sensor wire harness 120, the second sensor wire harness 170, the traction wire and the laser optical fiber 110 move together. In addition, it also includes step S210 of sleeving the first sleeve 140 outside the first sensor wire harness 120, the second sensor wire harness 170, the traction wire and the laser optical fiber 110 to form an inner layer part during the process of their joint movement; a temperature and pressure sensor 152 is arranged in front of the first sleeve 140 during the movement of the inner layer part, and the temperature and pressure sensor 152 is connected to the second sensor wire harness 170. In this way, the controllable bending optical fiber structure is provided with the functions of temperature measurement and pressure measurement. Specifically, the temperature and pressure sensor 152 includes a temperature measurement sensor and / or a pressure measurement sensor. For example, a temperature measurement sensor with a thermistor and a pressure measurement sensor with a piezoresistor can be arranged for measurement.
[0071] The laser optical fiber 110 prepared by the present disclosure includes an illumination optical fiber 190. Specifically, the illumination optical fiber 190 is used to provide light so that the lens assembly 150 can still clearly see the internal structure of the human body after entering the human body. More specifically, the drawn illumination optical fiber 190 will move together with the first sensor wire harness 120, the second sensor wire harness 170, the traction wire and the laser optical fiber 110, and the first sleeve 140 will be sleeved outside the first sensor wire harness 120, the second sensor wire harness 170, the traction wire, the laser optical fiber 110 and the illumination optical fiber 190 during the joint movement to form an inner layer part. At this time, the inner layer part includes the first sensor wire harness 120, the second sensor wire harness 170, the traction wire, the laser optical fiber 110 and the illumination optical fiber 190. Optionally, a protective sleeve 191 can be sleeved outside the illumination optical fiber 190.
[0072] In addition, the inner layer part may also include an infusion tube 180, and the infusion tube 180 only needs to move together with the laser optical fiber 110 to be sleeved by the first sleeve 140. The purpose of setting the infusion tube 180 is as follows: First, when the laser of the laser optical fiber 110 acts on the calculus, it will bring high temperature, and the infusion tube 180 is set to reduce the body temperature; Second, the crushed calculus is taken out through the perfusion fluid of the infusion tube 180; Third, the front end of the controllable bending optical fiber structure is cleaned through the perfusion fluid of the infusion tube 180 to prevent the front-end lens 151 from being blocked and ensure a clear view field of the surgical area.
[0073] Optionally, the rear ends of the first sensor wire harness 120, the traction wire and the laser optical fiber 110 protrude from the first sleeve 140 and the second sleeve 160 and are located behind the first sleeve 140 and the second sleeve 160. The purpose of the above design is to install the rear ends of the first sensor wire harness 120 and the traction wire on the control handle 200.
[0074] Optionally, before the lens assembly 150 is disposed in front of the first sleeve 140 during the movement of the inner layer portion, a coiled tube 141 is disposed in front of the first sleeve 140 such that the coiled tube 141 is located between the first sleeve 140 and the lens assembly 150. The second sleeve 160 should be sleeved outside the coiled tube to prevent the coiled tube from being exposed.
[0075] Optionally, the controllable bending optical fiber structure includes an illumination optical fiber 190 and a second sensor wire harness 170, and the second sensor wire harness 170 and the illumination optical fiber 190 are located inside the first sleeve 140.
[0076] More specifically, the front end of the laser optical fiber 110 protrudes 10 cm from the front end of the illumination optical fiber 190, and the front end of the illumination optical fiber 190 is arranged side by side with the front end of the infusion tube 180 and the front end of the traction wire. The front end of the illumination optical fiber 190 protrudes 0.5 cm from the front ends of the first sensor wire harness 120 and the second sensor wire harness 170, that is, the front end of the laser optical fiber 110 protrudes 10.5 cm from the front ends of the first sensor wire harness 120 and the second sensor wire harness 170.
[0077] The first sleeve 140 is arranged side by side with the first sensor wire harness 120 and the second sensor wire harness 170. That is, the front end of the illumination optical fiber 190, the front end of the infusion tube 180, and the front end of the traction wire protrude from the first sleeve 140. The front end of the second sleeve 160 is located in front of the first sleeve 140 and is connected to the lens assembly 150.
[0078] In addition, a coiled tube 141 is provided between the front end of the first sleeve and the lens assembly 150. The coiled tube 141 mainly provides a certain hardness and support force for the controllable bending optical fiber structure to prevent the front end of the controllable bending optical fiber structure from being completely deformed when bent.
[0079] The coiled tube 141 can be a hollow tube made of metal or non-metal material and cut with grooves, specifically as Figure 9 shown. The shape of the groove can be one or a combination of a water droplet shape, a bullet shape, a waist-shaped hole, a circular shape, a spiral shape, etc. The density of the proximal end, the middle section, and the distal end is different, and the shapes can be the same or different. Moreover, the coiled tube can have a certain elasticity to facilitate the reset of the controllable bending optical fiber structure.
[0080] In addition, the present disclosure provides a device for preparing a controllable bending optical fiber structure, including: an optical fiber drawing machine 310, a moving device, a first sleeve device, a robotic arm 330, a dispensing machine 340, a second sleeve device, a monitoring device 370, and a control component 380. For details, see Figure 12。The optical fiber drawing machine 310 is used to draw the laser optical fiber 110. The moving device can drive the laser optical fiber 110, the first sensor wire harness 120, and the traction wire to move respectively. Specifically, the moving device includes several pairs of conveyor belts 320 and several robotic arms 330. More specifically, before the first sensor, the traction wire, and the laser optical fiber 110 are sleeved in the first sleeve 140, multiple pairs of conveyor belts (each pair of conveyor belts includes two conveyor belts) 320 can be used to clamp them respectively to drive their movement. After the first sensor, the traction wire, and the laser optical fiber 110 are externally sleeved with the first sleeve 140, the robotic arm 330 can be used to drive the laser optical fiber 110 to move so as to drive the first sensor, the traction wire, and the first sleeve 140 to move. The movement of other structures (such as the second sensor wire harness 170 and the infusion tube 180) can be selectively carried out by using the conveyor belt 320 or the robotic arm 330 according to the situation.
[0081] It should be noted that when using the conveyor belt 320 to drive an object to move, a pair of conveyor belts 320 are used to clamp the object and drive the object to move through the conveyor belt 320.
[0082] The first sleeve device is used to sleeve the first sleeve 140 outside the first sensor wire harness 120, the traction wire, and the laser optical fiber 110. Specifically, the first sleeve device can be the first extruder 350. The first extruder 350 is used to extrude on the first sensor wire harness 120, the traction wire, and the laser optical fiber 110 to form the first sleeve 140 sleeved on the first sensor wire harness 120, the traction wire, and the laser optical fiber 110. The robotic arm 330 and the dispensing machine 340 are used to install the lens assembly 150 before the first sleeve 140.
[0083] The second sleeve device is used to sleeve the second sleeve 160 outside the first sleeve 140. Specifically, the second sleeve device is the second extruder 360, which is used to extrude outside the first sleeve 140 to form the second sleeve 160.
[0084] The monitoring device 370 is used to monitor the moving speeds of the laser optical fiber 110, the first sensor wire harness 120, and the traction wire. Among them, the monitoring device 370 can be an infrared detection device or the like, which is a device capable of detecting the passing of an object.
[0085] The control component 380 is signal-connected to the optical fiber drawing machine 310, the moving device, the first extruder 350, the robotic arm 330, the dispensing machine 340, the second extruder 360, and the monitoring device 370 respectively. The control component 380 generally controls operations such as the optical fiber drawing machine 310, the moving device, the first extruder 350, the robotic arm 330, the dispensing machine 340, the second extruder 360, and the monitoring device 370, such as operations associated with display, data communication, and recording operations. The control component 380 can include one or more processors to execute instructions.
[0086] More specifically, when the positions of structures such as the first sensor harness 120, the traction wire, and the laser optical fiber 110 are not arranged at the preset positions, the control component 380 can control the moving device to adjust the moving speeds of the structures such as the first sensor harness 120, the traction wire, and the laser optical fiber 110, so that the structures are arranged at the preset positions.
[0087] Meanwhile, the control component 380 can control the extrusion speeds of the first extruder 350 and the second extruder 360, so that the extruders extrude at a predetermined speed to form the first sleeve 140 and the second sleeve 160.
[0088] The method for preparing the controllable-bend optical fiber structure of the present disclosure can produce a controllable-bend optical fiber structure with a lens 151. The controllable-bend optical fiber structure can observe the internal conditions of a patient through the lens assembly 150, and control the bending of the laser optical fiber 110 through the traction wire so that the laser can crush the stones in the patient's body. Meanwhile, an infusion tube is provided to supply perfusion fluid for cooling and cleaning the lens, ensuring the safety and efficiency of the entire operation.
[0089] Secondly, the preparation method can complete the assembly during the movement of component production, avoiding the low production efficiency caused by separate execution of each step. Specifically, after the laser optical fiber 110 is drawn, it is not necessary to place it on the turntable anymore. The user can directly adjust the transmission speeds of the first sensor harness 120 and the traction wire according to the drawing speed of the laser optical fiber 110, and keep the speeds of the three consistent to complete extrusion and then sleeve the first sleeve 140, greatly reducing the preparation time.
