Description

Rotary frame assembly and flexible wire delivery system comprising the same TECHNICAL FIELD

[0001] The present invention relates to a flexible wire delivery system for delivering a flexible wire, in particular to a rotary frame assembly of the flexible wire delivery system. The flexible wire delivery system is particularly used for delivering a flexible wire, such as a flexible endoscope insertion tube in the medical field, or other flexible wires in other fields. BACKGROUND

[0002] Delivery of flexible wires plays an important role in many industries and application scenarios, such as delivery of cable wires, delivery of optical fiber wires, delivery of robot cables, etc. There are also many application scenarios of flexible wire delivery in medical devices, for example, cardiovascular guide wires, which are very thin and flexible metal or composite wires, play a guiding role in cardiovascular intervention treatment, and help doctors guide other instruments (such as catheters, stents, etc.) to reach the target lesion position in the patient's vascular system through the delivery of cardiovascular guide wires.

[0003] Delivery of flexible wires also has applications in the field of flexible endoscopes. Endoscopes can enter the human body through natural orifices of the human body, small incisions formed by surgery, etc., and doctors can see the situation in the internal cavity of the human body through the endoscope, for example, to check the situation in the human body, help doctors perform surgery, etc. The insertion tube of the flexible endoscope is flexible (or soft), which can pass through the curved passageway in the human body to reach the target position. The traditional endoscope insertion tube is manually inserted into the natural cavity of the human body by the doctor, and while pushing the endoscope insertion tube forward into the human body, the doctor can also rotate the endoscope insertion tube, so that the endoscope can pass through the tortuous passageway and reach the desired position.

[0004] In order to facilitate the doctor to remotely control the insertion of the endoscope insertion tube, endoscope delivery robots have begun to be popularized in endoscopic surgery. The existing endoscope robots mainly hold the endoscope insertion tube at one end by a robot arm, and then deliver the endoscope insertion tube into the human body by moving the robot arm forward and backward.

[0005] The existing endoscope delivery robot exhibits some technical problems in use. For example, in the existing endoscope delivery robot, the endoscope insertion tube needs to be rotated while being pushed forward into the human body, and the endoscope delivery robot also needs to include a rotating mechanism, such as a rotating frame, on which the delivery device for delivering the endoscope insertion tube is installed, so as to realize rotation of the endoscope insertion tube. In such a structure, the rotation center line of the rotating mechanism needs to be collinear with the axis of the endoscope insertion tube, and therefore a sterile plug is provided between the rotating mechanism and the endoscope insertion tube to prevent the rotating mechanism from contaminating the endoscope insertion tube. However, in the process of installing the sterile plug, the edge of the sterile plug still has a risk of being contaminated, which in turn causes the endoscope insertion tube to be contaminated.

[0006] Moreover, when the endoscope delivery and rotating mechanism is installed, a bacteria-proof cover needs to be provided between the reusable device and, for example, the disposable consumables. The structure of the existing endoscope delivery robot makes the installation of the bacteria-proof cover complicated, and requires good operation skills of the operator to prevent contamination of the human body entering component such as the endoscope insertion tube during the installation process.

[0007] Therefore, in the field, there is a need to improve the existing flexible wire delivery system. SUMMARY

[0008] The present application is made to solve the problems of the prior art described above. The purpose of the present application is to provide a rotating frame with an improved structure and a flexible wire delivery system using the same, which allows the bacteria-proof cover to be easily provided to ensure the sterile state of the components such as the flexible wire.

[0009] The rotating frame assembly of the present application is used to rotate the flexible wire delivery device, which comprises a rotating frame body connected with the flexible wire delivery device and a driving device connected with the rotating frame body. The rotating frame body is arranged to be able to rotate around the rotation axis under the driving of the driving device, and the rotating frame assembly is arranged such that the driving device and the rotating frame body do not interfere with the rotation axis during rotation of the rotating body.

[0010] The rotation axis of the rotating frame assembly is a virtual axis, because the driving device and the rotating frame body do not interfere with the rotation axis during the rotation of the rotating frame body. This structure can be achieved, for example, by spacing the rotating frame body and the driving device from the rotation axis around which the rotating frame body rotates. In addition, when the flexible wire material conveying system is installed on the rotating frame assembly, the longitudinal axis of the flexible wire material needs to be aligned with the virtual rotation axis. In this way, the components of the rotating frame assembly do not interfere with the flexible wire material, which means that the sterile isolation between the rotating frame assembly and the flexible wire material can be achieved simply by covering the rotating frame assembly with a sterile cover, without the need for a complex sterile plug as in the prior art.

[0011] In a specific structure, the rotating frame body includes an arc-shaped component, which includes a circular arc surface on which the driving device acts to drive the rotating frame body to rotate. The rotation axis is located on the side of the rotating frame body opposite the circular arc surface and passes through the center of the circular arc surface. In this structure, the rotation axis of the arc-shaped component is outside the arc-shaped component, thereby ensuring that the arc-shaped component does not interfere with the rotation axis during rotation.

[0012] Optionally, the driving device includes a first motor and a transmission mechanism connected between the first motor and the circular arc surface of the rotating frame body.

[0013] In addition, the rotating frame body is provided with an arc-shaped slot that extends through the rotating frame body, and the arc of the arc-shaped slot is consistent with the arc of the circular arc surface. The rotating frame assembly further includes a first bearing member disposed in the arc-shaped slot to guide the radial positioning of the rotating frame body.

[0014] Additionally, the rotating frame assembly further includes a second bearing member disposed on the arc-shaped surface and cooperating with the first bearing member to guide the radial positioning of the rotating frame body.

[0015] The first bearing member and the second bearing member help to fix the radial position of the arc-shaped component and ensure that the arc-shaped component rotates strictly around the rotation axis. The first bearing member disposed in the arc-shaped slot is preferably formed of metal to be able to withstand a larger pressure. The second bearing member on the circular arc surface can be made of plastic to reduce the overall manufacturing cost of the device, as it withstands less pressure.

[0016] Regarding the specific structure of the transmission mechanism, in one example, a rack is formed on the circular arc surface, and the transmission mechanism includes at least one gear that engages with the rack and is directly or indirectly driven by the first motor.

[0017] Optionally, the at least one gear includes a first gear and a second gear, the first gear is connected to the output shaft of the first motor, and the second gear is engaged with the first gear and the rack respectively.

[0018] The present application also provides a flexible wire conveying system, which includes a flexible wire conveying device configured to linearly convey the flexible wire along the direction of the longitudinal axis of the flexible wire. The flexible wire conveying system also includes the rotating frame assembly as described above, wherein the rotating frame body of the rotating frame assembly is fixedly connected to the flexible wire conveying device, and the rotation axis of the rotating frame body coincides with the longitudinal axis of the flexible wire.

[0019] Optionally, the flexible wire conveying device includes a conveying seat assembly and a conveying disc assembly, the conveying seat assembly and the conveying disc assembly are installed together, and the rotating frame assembly is fixedly connected to the conveying seat assembly. Further optionally, the flexible wire conveying system also includes a bacteria-proof cover capable of covering the conveying seat assembly and the rotating frame assembly.

[0020] As can be seen from the above structure, the conveying disc assembly is relatively fixedly connected to the rotating frame assembly through the conveying seat assembly. Before the conveying disc assembly is connected, the rotating frame assembly and the conveying seat assembly can be simply covered with the bacteria-proof cover without affecting the operation of connecting the conveying disc assembly to the conveying seat assembly.

[0021] In some application scenarios, for example, in the case where the flexible wire to be conveyed is an endoscope insertion tube, the flexible wire conveying system also includes a breathing assembly. The conveying seat assembly further includes a breathing assembly connecting portion for connecting with the breathing assembly.

[0022] In a specific optional structure, the conveying disc assembly includes a conveying mechanism. The conveying mechanism includes a clamping conveying part in which a wire passage is formed for the flexible wire to pass through, and a compression limiting part including a pressing plate that presses a portion of the clamping rotating part from one side of the wire passage, so that the size of the portion of the wire passage corresponding to the compression limiting part is smaller than the size of the remaining portion of the wire passage, to generate a friction fit between the clamping conveying part and the flexible wire.

[0023] More specifically, the clamping conveying part includes a first rotating disc and a second rotating disc fixed to each other with a gap therebetween, the gap forming a portion of the wire passage; and wherein the first rotating disc includes a hub portion and a plurality of fingers extending radially outward from the hub portion, and the pressing plate presses on a portion of the fingers on the side of the first rotating disc facing away from the second rotating disc, so that the corresponding fingers are deformed towards the second rotating disc.

[0024] To increase the clamping of the flexible wire and prevent the flexible wire from slipping in the clamping conveying part during conveying, at least one of the following structures can be provided: a first friction enhancer is provided on the surface of the side of the first turntable facing the second turntable, and / or a second friction enhancer is provided on the surface of the side of the second turntable facing the first turntable.

[0025] In a specific embodiment, at least one of the first friction enhancer and the second friction enhancer is made of a silica gel material. Alternatively or additionally, at least one of the first friction enhancer and the second friction enhancer is formed with at least one of a textured portion and a concave-convex portion.

[0026] Optionally, the top of the housing is formed with an opening, and the opening is formed with a notched portion on two sides arranged opposite in the running direction of the flexible wire, and in the installed state, the notched portion is aligned with the gap, so that the notched portion and the gap cooperate to form a wire passage.

[0027] Optionally, a compression limiting part is installed on the housing and closes the opening, and when the compression limiting part is installed on the housing to close the opening, the pressing plate is pressed on the side of the first turntable facing away from the second turntable.

[0028] Optionally, the compression limiting part and the housing are connected together through a snap structure. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0058] For the purpose of facilitating the understanding of the present application, the detailed description of the embodiments of the rotating frame and the flexible wire conveying system including the rotating frame will be given below with reference to the accompanying drawings. It should be understood that the preferred embodiments shown in the drawings should not be construed as limiting the scope of the present application. Those skilled in the art can make various modifications, variations, equivalent replacements to the embodiments shown in the drawings on the basis of the present application, and the technical features described in the different embodiments below can be combined with each other arbitrarily without contradiction, which all fall within the scope of the present application.

[0059] The terms used to express the orientation, such as "top", "upper", "lower", used in the following disclosure are based on the orientation of the rotating frame and the flexible wire conveying system in the actual use state.

[0060] Fig. 1 shows an exemplary overall perspective view of the flexible wire conveying system 10 of the present application. Fig. 2 shows a sectional view of the flexible wire conveying system 10 of Fig. 1.

[0061] As shown in Figs. 1 and 2, the flexible wire conveying system 10 includes a flexible wire conveying device, which includes a conveying reel assembly 100 and a conveying seat assembly 40, and a flexible wire, such as an endoscope insertion tube 20, can be continuously and linearly conveyed by the conveying reel assembly 100 of the flexible wire conveying device into the human body. It should be understood that the present application takes the endoscope insertion tube as an example of the flexible wire, and the flexible wire described in the present application can also be other cables or pipes, such as a cable wire, an optical fiber wire, a medical guide wire, etc.

[0062] The flexible wire conveying system 10 further includes a rotating frame assembly 30, which is connected to the flexible wire conveying device, for example, to the conveying seat assembly 40 of the flexible wire device in the structure shown in the drawings, and is capable of driving the flexible wire conveying device to rotate about a rotation axis X. The rotation axis X is preferably consistent with the longitudinal axis of the endoscope insertion tube 20.

[0063] The flexible wire conveying system 10 further includes a breathing assembly 50, which is connected to the flexible wire conveying device, for example, to the conveying seat assembly 40. The endoscope insertion tube 20 conveyed via the conveying reel assembly 100 can pass through the breathing assembly 50 and then enter the human body. The breathing assembly 50 is included, for example, in the flexible wire conveying system 10 used in the case of an endoscope. In this case, the endoscope insertion tube 20 enters the oral cavity of the human body, and in this process, the user can hold the catheter at the distal end of the breathing assembly 50 in the mouth to breathe.

[0064] The specific structure of each component of the flexible wire conveying system 10 and the connection mode therebetween will be described in detail below.

[0065] <Flexible wire conveying device>

[0066] The flexible wire conveying device of the flexible wire conveying system 10 of the present application includes a conveying disc assembly 100 and a conveying seat assembly 40. A perspective view of the conveying disc assembly 100 of the flexible wire conveying device is shown in FIG. 3, which is in the form of a rotary chuck mechanism. The conveying disc assembly 100 includes a housing 111 and a limiting cover 112 mounted on the top of the housing 111. A clamping conveying member 113 is rotatably mounted in the housing 111, as shown in FIG. 4.

[0067] In the preferred structure shown in the drawings, the housing 111 is formed by two half-housings cooperating with each other, so that it is convenient to mount the clamping conveying member 113 and other components therein, or to disassemble the conveying disc assembly 100. Of course, the housing 111 can also be integrally formed as a one-piece structure, which is also within the scope of the present application.

[0068] FIG. 5 shows a perspective view of the clamping conveying member 113 provided in the housing 111 of the conveying disc assembly 100, which includes a first chuck 120 and a second chuck 130 fixed together with an overlap, and has a gap between the first chuck 120 and the second chuck 130. The endoscope hose 20 conveyed by the conveying disc assembly 100 can be accommodated in the gap.

[0069] The preferred specific structure of the first chuck 120 and the second chuck 130 will be described below in conjunction with FIGS. 6 and 7.

[0070] FIG. 6 shows a perspective view of the first chuck 120, in which the side of the first chuck 120 facing the second chuck 130 is shown. The first chuck 120 has a hub portion 121 and a plurality of fingers 122 extending radially outward from the hub portion 121, so as to have a radial shape. The fingers 122 have one end connected to the hub portion 121 and the other end as a free end, so that the fingers 122 are formed in the form of a cantilever. In this way, when a force is applied to the fingers 122, for example, a pressing force is applied at or near the free end of the fingers 122, the fingers 122 can be elastically deformed. At least part of the fingers 122 in the first chuck 120 is made of an elastically deformable material, such as an elastic plastic such as thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), thermoplastic polyolefin (TPO), an elastic metal such as steel, and the like.

[0071] Preferably, a first friction enhancer 123 is provided on the surface of the second chuck 130 facing the first chuck 120, and the first friction enhancer 123 covers at least a portion of the fingers 122. Preferably, the portion of the fingers 122 near the free ends thereof is covered with the first friction enhancer 123, and this portion of the fingers 122 is also the portion that will contact the endoscope tube 20 during the process of straightly conveying the endoscope tube 20.

[0072] FIG. 7 shows a perspective view of the second chuck 130, and the side of the second chuck 130 facing the first chuck 120 is shown. A cylindrical portion 131 is formed at the center hub of the second chuck 130, and the cylindrical portion 131 can accommodate a rotating shaft mechanism for clamping the conveying member 113, the specific structure of which will be described below. Correspondingly, as shown in FIG. 6, a central hole 124 is formed at the hub 121 of the first chuck 120. When the first chuck 120 and the second chuck 130 are fixedly installed together, the cylindrical portion 131 can extend into and pass through the central hole 124.

[0073] Preferably, a second friction enhancer 132 is provided on the surface of the second chuck 130 facing the first chuck 120, and the second friction enhancer 132 is preferably provided on the outer periphery of the second chuck 130, and the position of the second friction enhancer 132 corresponds to the position of the first friction enhancer 123 on the fingers 122 of the first chuck 120. In this way, when the endoscope tube 20 is conveyed, the fingers 122 and the second friction enhancer 132 can contact the endoscope tube 20 from both sides of the endoscope tube 20, thereby increasing the friction at the positions where the first chuck 120 and the second chuck 130 contact the endoscope tube 20.

[0074] Preferably, the first friction enhancer 123 and the second friction enhancer 132 are made of, for example, a silicone material, which helps to increase the friction between the first chuck 120 and the second chuck 130 and the endoscope tube 20. At the same time, silicone is a relatively soft material, and the use of silicone can avoid or at least significantly reduce damage to the endoscope tube 20 when the first chuck 120 and the second chuck 130 contact the endoscope tube 20.

[0075] As an additional or alternative solution, the first friction enhancer 123 and the second friction enhancer 132 can also include structures or patterns that can increase the friction, such as including textured portions, concave-convex portions, and the like.

[0076] Preferably, a plurality of partition ribs 133 are formed on the second chuck 130, preferably on the inner side with respect to the second friction-enhancing member 132. Also, when the first chuck 120 and the second chuck 130 are assembled together, the partition ribs 133 enter the gaps between the adjacent two fingers 122 on the first chuck 120. By providing the partition ribs 133, it is possible to prevent the adjacent two fingers 122 from colliding with each other during the conveying of the endoscope tube 20.

[0077] In addition, the partition ribs 133 also function to support the endoscope insertion tube 20 during the conveying of the endoscope insertion tube 20. In other words, during the conveying, the endoscope insertion tube 20 is supported on the side of the partition ribs 133 facing the radial outer side of the second chuck 130, and is conveyed forward under the action of the clamping force on both sides.

[0078] The fixed connection between the first chuck 120 and the second chuck 130 can be achieved in various ways. For example, in the exemplary structure shown in Figs. 6 and 7, the fixed connection is achieved by the mating structure between the mounting protrusion 125 on the first chuck 120 and the mounting hole 134 on the second chuck 130. As an additional or alternative solution, the fixed connection can also be achieved by a screw that is screwed into the first screw hole 126 on the first chuck 120 and the second screw hole 135 on the second chuck 130.

[0079] In addition to the structure shown in the figures, the first chuck 120 and the second chuck 130 can also be fixedly connected together by other known structures. For example, by a snap-fit structure, a threaded connection structure, etc.

[0080] Referring to Fig. 8, the assembled housing 111 and the clamping and conveying member 113 are shown. The top of the housing 111 includes an opening, and both sides of the opening are provided with a bayonet portion 114, which is formed, for example, by opening a notch portion on the edge of the opening on the top of the housing 111. The bayonet portion 114 is aligned with the gap between the first chuck 120 and the second chuck 130 of the clamping and conveying member 113 in the conveying direction of the endoscope tube 20, thereby forming a wire passage for conveying the endoscope tube 20.

[0081] A limiting cover 112 is mounted on the top of the housing 111 to close the opening on the top of the housing 111. Figs. 9a-10 show the specific structure of the limiting cover 112.

[0082] As shown in Fig. 9a, the position-limiting cover 112 includes a top wall 115 and two side walls 116 on both sides of the top wall 115. A presser 141 extending downward is arranged inside the top wall 115. The presser 141 shown in Fig. 9a is specifically in the form of a press plate arranged to extend substantially parallel to the side walls 116. When the position-limiting cover 112 is installed on the housing 111, the presser 141 can be in contact with the fingers 122 of the first chuck 120, specifically with the side surface of the fingers 122 facing away from the second chuck 130, and exerts a pressing force on the fingers 122 in the direction of the second chuck 130.

[0083] Preferably, the presser 141 is made to have a thickness smaller at both sides than in the middle part, and a slope or arc-shaped structure is formed between the two sides and the middle part, as can be seen from Fig. 11. Such a structure can help to smoothly guide the fingers 122 of the first chuck 120 to the thicker part of the presser 141. Specifically, during the rotation of the clamping and conveying member 113, the fingers 122 of the first chuck 120 first contact the thinner sides of the presser 141, and then are guided to the thicker middle part under the action of the slope or arc-shaped structure between the sides and the middle part, thereby pressing the fingers 122 to deform toward the endoscope tube 20, and the gradually deformed fingers 122 cooperate with the second chuck 130 to gradually press the endoscope insertion tube 20. When the endoscope insertion tube 20 is pressed, it is conveyed forward under the action of the pressing force. With the rotation of the first chuck 120 and the second chuck 130, the fingers 122 previously pressed and deformed by the presser 141 will successively come out of contact with the presser 141 and recover their original shape, thereby relaxing the pressing on the corresponding part of the endoscope insertion tube 20. At the same time, the subsequent fingers 122 will enter the position cooperating with the presser 141, thereby pressing the subsequent part of the endoscope insertion tube 20.

[0084] In the structure of the present application, it can be ensured that at least one finger 122 is always in cooperation with the presser 141 and presses the endoscope insertion tube 20 during the conveying process, so that the endoscope insertion tube 20 can be continuously conveyed forward.

[0085] The limit cap 112 can be mounted to the housing 111 in various ways. For example, in the exemplary structure shown in FIG. 9b, a catch 142 is provided on the limit cap 112, which can cooperate with a catch groove 117 on the top of the housing 111. In addition, a catch operating mechanism is also provided in the limit cap 112 for each catch 142. As shown in FIG. 10, a hole is formed in each side wall 116, in which a catch button 143 is provided. The catch button 143 can be integrally formed with the catch 142, or the catch button 143 and the catch 142 are separately formed and connected together. A first spring 144 is provided on the catch button 143, which is arranged to bias the catch button 143 outwardly of the limit cap 112. When the limit cap 112 is placed on the top of the housing 111, the top edge of the housing 111 comes into contact with the catch 142, pressing the catch 142 so that it deforms inwardly of the limit cap 112. As the catch 142 travels downwardly and reaches the position of the catch groove 117, the force acting on the catch 142 disappears, and the catch 142 returns to its original shape and cooperates with the catch groove 117. Moreover, the biasing action of the first spring 144 on the catch button 143 causes the catch 142 connected with the catch button 143 to also be biased to the position of cooperation with the catch groove 117. In this way, the cooperation between the catch 142 and the catch groove 117 fixes the limit cap 112 in place.

[0086] When it is necessary to remove the limit cap 112 from the housing 111, the catch button 143 can be pressed to move inwardly of the limit cap 112 against the spring force of the first spring 144, and the catch 142 connected with the catch button 143 also moves inwardly of the limit cap 112, disengaging from the cooperation with the catch groove 117. In this way, the operator can easily remove the limit cap 112 from the housing 111.

[0087] Returning to FIG. 9a, it can be seen that a limit rib 145 is also formed on the inner side surface of the top wall 115. When the limit cap 112 is mounted to the housing 111, the limit rib 145 is aligned with the gap between the first chuck 120 and the second chuck 130, thereby defining the top of the wire passage for conveying the endoscope hose 20. In this way, the limit rib 145 cooperates with the first chuck 120 and the second chuck 130 to retain the endoscope hose 20 in the wire passage, ensuring the continuous conveying of the endoscope hose 20.

[0088] The connection structure between the transport disc assembly 100 and the transport seat assembly 40 will be described below in connection with Figs. 12a-14b. As can be seen from Fig. 12a, a plurality of transport disc buckles 152 are provided on the side of the transport disc assembly 100 facing the transport seat assembly 40. Correspondingly, as shown in Fig. 12c, a corresponding number of transport seat buckling grooves 151 are formed on the corresponding side of the transport seat assembly 40. When the transport disc assembly 100 is mounted on the transport seat assembly 40, the transport disc buckles 152 are fitted into the transport seat buckling grooves 151, and then by rotating the transport disc assembly 100 relative to the transport seat assembly 40, the transport disc buckles 152 are buckled into the transport seat buckling grooves 151, thereby achieving the fixation of the transport disc assembly 100 on the transport seat assembly 40.

[0089] A plurality of transport seat spring posts 153 are also provided on the transport seat assembly 40, which exert an outwardly lifting force on the transport disc assembly 100 when the transport disc assembly 100 is mounted on the transport seat assembly 40, further improving the reliability of the fixed fit between the transport seat buckling grooves 151 and the transport disc buckles 152.

[0090] A transport disc rotating shaft 157 is also provided on the transport disc assembly 100. The structure of the transport disc rotating shaft 157 is more clearly shown in the cross-sectional view of Fig. 12b. One end of the transport disc rotating shaft 157 is accommodated in the cylindrical portion 131 of the second chuck 130, and the other end extends out of the housing 111. Preferably, a second spring 158 is provided on the end accommodated in the cylindrical portion 131, which biases the transport disc rotating shaft 157 towards the position extending out of the housing 111.

[0091] A motor connecting shaft 156 is correspondingly provided on the transport seat assembly 40, which is connected to the output shaft of the motor 41 (see Fig. 13) as shown in Figs. 12c and 13. Furthermore, a receiving hole is formed in the center of the motor connecting shaft 156, into which the transport disc rotating shaft 157 of the transport disc assembly 100 can be inserted. When the transport disc assembly 100 is mounted on the transport seat assembly 40, the transport disc rotating shaft 157 is inserted into the motor connecting shaft 156. In this way, when the motor 41 is operated, it drives the motor connecting shaft 156 to rotate, which in turn drives the transport disc rotating shaft 157 to rotate, and the rotation of the transport disc rotating shaft 157 causes the clamping transport member 113 to rotate.

[0092] Preferably, the conveying disc rotating shaft 157 has a non-circular cross section, such as a triangular cross section as shown in the figure. Correspondingly, the hole in the motor connecting shaft 156 has a cross section shape matching that of the conveying disc rotating shaft 157, such as also a triangular cross section. In addition to the triangular cross section shown in the figure, the conveying disc rotating shaft 157 and the hole in the motor connecting shaft 156 can also have other non-circular shapes, such as a rectangular shape, a polygonal shape, etc. In this way, the motor connecting shaft 156 can effectively transmit the torque from the motor to the conveying disc rotating shaft 157, thereby driving the clamping conveying component 113 to rotate.

[0093] The conveying seat assembly 40 is further provided with a limiting shaft 154, and the conveying seat spring post 153 is connected with or integrally formed with a limiting shaft button 161. The limiting shaft button 161 is provided with a third spring 162, which biases the limiting shaft button 161 and the limiting shaft 154 outward from the conveying seat assembly 40.

[0094] Correspondingly, the conveying disc assembly 100 is provided with a limiting hole 155. During the installation of the conveying disc assembly 100 to the conveying seat assembly 40, when the conveying disc assembly 100 is rotated relative to the conveying seat assembly 40 to a position where the conveying disc buckle 152 is fitted into the conveying seat slot 151, the limiting shaft 154 will be extended and fitted into the limiting hole 155 under the action of the third spring 162. In this way, after installation, the rotation of the conveying disc assembly 100 relative to the conveying seat assembly 40 can be prevented, thereby preventing the conveying disc assembly 100 and the conveying seat assembly 40 from being accidentally detached.

[0095] When it is necessary to detach the conveying disc assembly 100 from the conveying seat assembly 40, the operator can push the limiting shaft button 161 against the elastic force of the third spring 162, so that the limiting shaft 154 is detached from the limiting hole 155. At this time, the operator can rotate the conveying disc assembly 100 in a direction opposite to the direction of installing the conveying disc assembly 100, to a position where the conveying disc buckle 152 is detached from the conveying seat slot 151, so that the conveying disc assembly 100 can be removed from the conveying seat assembly 40.

[0096] Further, the flexible wire conveying device is further provided with an identification device. Specifically, as shown in FIG. 14a, a first Hall induction plate 163 is arranged on the side of the conveying seat assembly 40 facing the conveying disc assembly 100, and a first induction magnet 164 is arranged on the conveying disc assembly 100. During the connection of the conveying disc assembly 100 and the conveying seat assembly 40, if the first Hall induction plate 163 senses the first induction magnet 164, it indicates that the conveying disc assembly 100 and the conveying seat assembly 40 are connected in place with the correct relative position. Alternatively, the first induction magnet 164 can be arranged, for example, on the inner surface of the half shell of the housing 111 adjacent to the conveying seat assembly 40.

[0097] In addition, a second sensing magnet 165 can also be provided on the limiting cover 112, as shown in FIG. 14b. When the limiting cover 112 is installed on the housing 111 of the conveying disc assembly 100, and the conveying disc assembly 100 is connected to the conveying seat assembly 40, the first Hall sensing plate 163 can detect the second sensing magnet 165, thereby determining that the limiting cover 112 is correctly installed in place.

[0098] Returning to FIG. 14a, optionally, an RFID chip 166 can also be provided in the housing 111, and an RFID antenna 167 can be provided on the side of the conveying seat assembly 40 facing the conveying disc assembly 100. The RFID chip 166 can record information of the conveying disc assembly 100, and the RFID antenna 167 can read the information recorded in the RFID chip 166 and transmit the information to an operator, such as to a control panel (not shown) of the flexible wire conveying system 10, etc.

[0099] Returning to FIG. 12c, it is shown that the conveying seat assembly 40 is formed with a rotating frame connecting portion 410 and a breathing assembly connecting portion 420. Through the rotating frame connecting portion 410, the conveying seat assembly 40, and further the flexible wire conveying device, can be fixedly connected to the rotating frame assembly 30. Through the breathing assembly connecting portion 420, the conveying seat assembly 40 and the breathing assembly 50 can be fixedly connected together. The specific structures of the rotating frame assembly 30 and the breathing assembly 50 will be described in detail below.

[0100] <Rotating frame assembly>

[0101] FIGS. 15a to 17 show exemplary specific structures of the rotating frame assembly 30 of the flexible wire conveying system 10.

[0102] FIG. 15a shows a perspective view of the rotating frame assembly 30, and FIG. 15b shows a sectional view of the rotating frame assembly 30 taken along line A-A in FIG. 15a. The rotating frame assembly 30 includes a rotating frame body 310 and a transmission mechanism 320 for driving the rotating frame body 310 to rotate. The rotating frame assembly 30 further includes a rotating frame housing 330, which accommodates the transmission mechanism 320 and can partially accommodate the rotating frame body 310. A mechanical arm connecting portion 331 is further provided on the rotating frame body 310 for connecting with a mechanical arm (not shown) of the flexible wire conveying system 10.

[0103] FIGS. 16a and 16b show two other perspective views of the rotating frame assembly 30, in which the rotating frame housing 330 is removed to more clearly show the structures and mutual connections and positional relationships of the components in the rotating frame assembly 30.

[0104] The first conveying seat connecting part 311 is formed on the rotating frame body 310 and is used to cooperate with the rotating frame connecting part 410 on the conveying seat assembly 40 shown in Fig. 12c to realize the fixed connection between the rotating frame assembly 30 and the conveying seat assembly 40. The rotating frame body 310 further comprises an arc-shaped part 312 which is connected together with or integrally formed with the first conveying seat connecting part 311. A rack 313 is formed on one side of the arc-shaped part 312.

[0105] The transmission mechanism 320 can be, for example, a gear train which comprises at least one gear. In the exemplary structure shown in Figs. 16a and 16b, the gear train which is the transmission mechanism 320 comprises two gears, a first gear 321 and a second gear 322. The rotating frame assembly 30 further comprises a second motor 323, and the rotation output by the second motor 323 can be transmitted to the arc-shaped part 312 through the transmission mechanism 320 to make the arc-shaped part 312 rotate. Specifically, the first gear 321 is connected with the output shaft of the second motor 323, one side of the second gear 322 is engaged with the first gear 321, and the other side is engaged with the rack 313. In this way, when the second motor 323 operates, the first gear 321 is driven to rotate, and the first gear 321 drives the arc-shaped part 312 to rotate around the rotation axis X passing through the center of the arc-shaped part 312 via the second gear 322 and the rack 313, which is more clearly shown in Fig. 1.

[0106] It can be understood in combination with Fig. 1 that the center of the arc-shaped part 312 is on the other side of the arc-shaped part 312 opposite to the side where the transmission mechanism 320 is located, and is spaced apart from the transmission mechanism 320 by a distance. In this way, when the rotating frame body 310 is driven to rotate, the transmission mechanism 320, especially the second motor 323, does not interfere with the rotation axis X. Therefore, for the rotating frame body 310, the rotation axis X is a virtual rotation axis. In this application, the rotation axis X of the rotating frame body 310 coincides with the longitudinal axis of the endoscope insertion tube 20, or in other words, coincides with the advancing path of the endoscope insertion tube 20.

[0107] Optionally, in the present application, the rotating frame assembly 30 can further comprise a support structure to maintain the radial position of the arc-shaped member 312. An exemplary structure of the support structure comprises at least one of a first bearing member 314 and a second bearing member 315. For example, in the structure shown in Figs. 16a and 16b, an arc-shaped slot 316 is formed through the arc-shaped member 312. At least one, for example two, first bearing members 314 are inserted into the arc-shaped slot 316. The two ends of the first bearing member 314 are fixed, for example, to the rotating frame housing 330, so that the first bearing member 314 remains stationary when the arc-shaped member 312 rotates, thereby serving to maintain the radial position of the arc-shaped member 312. The first bearing member 314 is preferably made of metal, so as to be able to withstand the relatively large pressure of the arc-shaped member 312.

[0108] Further, the rotating frame assembly 30 can further comprise at least one, for example two, second bearing members 315, which are carried on the arc surface of the arc-shaped member 312 where the rack 313 is formed. The second bearing members 315 can cooperate with the first bearing members 314 to ensure the radial position of the arc-shaped member 312. Since the pressure on the arc surface of the arc-shaped member 312 is relatively small, the second bearing members 315 can be made of plastic, for example, to reduce manufacturing cost.

[0109] Preferably, the rotating frame assembly 30 further comprises a position detecting member for detecting the rotation angle of the arc-shaped member 312, so as to prevent the arc-shaped member 312 from rotating excessively. The position detecting member comprises a second Hall sensor plate 342, which is fixed, for example, to the rotating frame housing 330. Correspondingly, a third sensing magnet 341 is provided on the arc-shaped member 312. During rotation of the arc-shaped member 312, if the second Hall sensor plate 342 detects the third sensing magnet 341, it indicates that the arc-shaped member 312 has reached its limit position and cannot continue to rotate in the same direction. At this time, the second motor 323 needs to be stopped or reversed, so as to stop or rotate the arc-shaped member 312 in the opposite direction.

[0110] Fig. 17 shows a cross-sectional view of the rotating frame assembly 30 taken along the line B-B in Fig. 15b. It is shown that a wear-resistant baffle 317 is optionally provided between the arc-shaped member 312 and the rotating frame housing 330, which can prevent or at least slow down the wear of the arc-shaped member 312 during rotation due to contact with the rotating frame housing 330, thereby prolonging its service life.

[0111] <Respiratory assembly>

[0112] FIG. 18 shows a perspective view of the breathing assembly 50. The breathing assembly 50 includes a breathing stand 510 and a breathing extension tube 520, which needs to be mounted to the breathing stand 510 before the surgery is performed.

[0113] The breathing extension tube 520 is formed with a flexible wire extension hole 521 via which the endoscope insertion tube 20 can extend through the breathing extension tube 520. The breathing stand 510 includes a breathing stand extension 511 which extends transversely, e.g. perpendicularly, to the extension direction of the endoscope insertion tube 20. The breathing extension tube 520 is mounted to one end of the breathing stand extension 511. A second delivery seat connecting portion 512 is formed on the other end of the breathing stand extension 511.

[0114] With continued reference to FIGS. 19a and 19b, which schematically show the delivery seat assembly 40 and the breathing assembly 50 before they are connected together, it can be clearly seen from them the connection structure between the delivery seat assembly 40 and the breathing assembly 50.

[0115] As can be seen from FIGS. 19a and 19b, the breathing assembly connecting portion 420 of the delivery seat assembly 40 includes a knob 421 which can be formed with internal threads, for example. Correspondingly, the second delivery seat connecting portion 512 on the breathing stand 510 includes external threads which can mate with the internal threads of the knob 421, thereby achieving the interconnection between the transmission mechanism 320 and the second delivery seat connecting portion 512. Specifically, when connecting the delivery seat assembly 40 and the breathing assembly 50, the breathing assembly connecting portion 420 of the delivery seat assembly 40 is aligned with the second delivery seat connecting portion 512 of the breathing assembly 50, and then the knob 421 is rotated, e.g. in the clockwise direction, to mate with the external threads of the second delivery seat connecting portion 512, thereby completing the connection. When it is needed to dismount the breathing assembly 50, the knob 421 is rotated in the opposite direction, e.g. in the counterclockwise direction, to disengage the breathing assembly connecting portion 420 from the second delivery seat connecting portion 512, so that the breathing assembly 50 can be removed.

[0116] Further optionally, a connecting groove 422 is formed at the end of the breathing assembly connecting portion 420, and a connecting key 513 is formed on the second delivery seat connecting portion 512. When the breathing assembly connecting portion 420 is aligned with the second delivery seat connecting portion 512, the connecting key 513 can be inserted into the connecting groove 422, thereby helping to fix the relative position between the breathing assembly connecting portion 420 and the second delivery seat connecting portion 512.

[0117] The above describes a specific embodiment of the flexible wire delivery system 10 of the present application. The operation of the flexible wire delivery system 10 will be described below in connection with FIG. 1.

[0118] The rotating stand assembly 30 and the transport base assembly 40 can be connected together as reusable devices before the operation is performed. Then, the transport tray assembly 100 and the breathing assembly 50, which are consumables, are respectively mounted to the transport base assembly 40.

[0119] Before the transport tray assembly 100 and the breathing assembly 50 are mounted, the rotating stand assembly 30 and the transport base assembly 40 can be integrally covered with a germ shield, so that the transport tray assembly 100 and the breathing assembly 50 can be prevented from being contaminated by the rotating stand assembly 30 and the transport base assembly 40 when they are mounted.

[0120] After the mounting, the clamping and transporting member 113 in the transport tray assembly 100 is driven to rotate by operating the first motor 41 in the transport base assembly 40, so as to continuously linearly transport the endoscope insertion tube 20. At the same time of linearly transporting the endoscope insertion tube 20, the rotating stand body 310 is driven to rotate around the virtual rotation axis X, which is consistent with the longitudinal axis of the endoscope insertion tube 20 loaded on the transport tray assembly 100 and the breathing assembly 50, by operating the transmission mechanism 320 of the rotating stand assembly 30, so as to realize the rotation of the endoscope insertion tube 20 around its own longitudinal axis.

[0121] Through the above description of the operation of the flexible wire transporting system 10 and in combination with FIG. 1, it can be seen that the virtual rotation axis X of the rotating stand body 310 of the rotating stand assembly 30 is spaced apart from the rotating stand assembly 30 as a whole, so that the rotating stand assembly 30 does not interfere with the endoscope insertion tube 20. And the consumables such as the transport tray assembly 100 and the breathing assembly 50 are not interfered with by the rotating stand assembly 30 during the mounting, so that the germ shield plug provided between the rotating stand and the endoscope insertion tube in the prior art can be omitted.

[0122] In addition, according to the above structure, the rotating stand assembly 30 and the transport base assembly 40 can be integrally covered with a germ shield, and then the transport tray assembly 100 and the breathing assembly 50 can be simply connected to the transport base assembly 40 which has been covered with the germ shield by the operator.

[0123] The exemplary structure of the flexible wire transporting system 10 of the present application and the operation mode thereof are described above. Those skilled in the art can make obvious modifications and variations on the basis of the above structure.

[0124] For example, the transmission mechanism 320 can be a combination of a gear and a transmission wheel-belt structure, in which the transmission wheel is connected with the output shaft of the second motor 323, and the transmission wheel transmits its rotating motion to the gear through the belt.

[0125] For example, the first bearing member 314 and the second bearing member 315 for securing the radial positioning of the rotating frame body 310 can be provided only one, and the number of the first bearing member 314 and the second bearing member 315 can be provided as needed.

[0126] In addition, the above-described embodiments are described by taking the delivery endoscope insertion tube 20 as an example. Those skilled in the art can understand that the device disclosed in the present application is also applicable to deliver other flexible cables or pipes, such as cable wires, optical fiber wires, medical guide wires, etc.

[0127] The above and other modifications and variations are within the scope of the present application.
