[0084] Figure 1 This is a schematic diagram of the structure of the support device provided in the embodiment of the present application. Figure 2 This is a schematic diagram of the structure of the support device at another angle provided in the embodiment of the present application, such as Figure 1 and Figure 2 As shown:

[0085] In order to solve the technical problems in the prior art, the embodiment of the present application provides a catheter support device 100, including: a main body 10, a first quick connector 20 and a second quick connector 30. The main body 10 includes a first end 101 and a second end 102 arranged opposite to each other, and the main body 10 can be telescopic along the direction from the first end 101 to the second end 102. The main body 10 has a support channel, and the support channel extends along the direction from the first end 101 to the second end 102. The support device 100 can support the catheter 500 through the support channel. The first quick connector 20 is connected to the first end 101 and communicates with the support channel. The second quick connector 30 is connected to the second end 102 and communicates with the support channel.

[0086] Combination Figure 1 and Figure 2 , see Figure 3 One use of the support device 100 is that the support device 100 can be used together with the catheter driving device 200, the catheter control box 300 and the external fixing member 400 to form a support system. The catheter control box 300 and the external fixing member 400 are respectively arranged at opposite ends of the catheter driving device 200, and the support device 100 is arranged between the catheter control box 300 and the external fixing member 400. The catheter driving device 200 can drive the catheter control box 300 to reciprocate in the direction where the external fixing member 400 is located.

[0087] The catheter control box 300 has a third quick connector 50 for connecting with the first quick connector 20, and the third quick connector 50 is also used to connect with the catheter 500. The third quick connector 50 is docked with the first quick connector 20, and the catheter 500 can enter the support channel through the first quick connector 20 and extend from the second quick connector 30. The support device 100 supports the catheter 500 through the support channel. It should be noted that in the embodiment of the present application, the catheter 500 includes but is not limited to medical hoses such as medical endoscopes, surgical catheters 500, navigation scopes, sheaths, etc. that can be used to enter the body cavity of the human body or animal. In the embodiment of the present application, the catheter 500 is used as an example for explanation, but it is not a specific limitation, and this is not an unfavorable limitation to the present application.

[0088] The external fixing member 400 has a fourth quick connector 60 for connecting with the second quick connector 30, and the fourth quick connector 60 is connected to the second quick connector 30. The external fixing member 400 includes but is not limited to being fixed to the patient's endotracheal cannula, so that the catheter 500 can more easily enter the inner cavity of the human lung.

[0089] The catheter drive device 200 is connected to the mechanical arm of the surgical robot. When the catheter 500 needs to be pushed into the human body, such as into the lungs. The catheter drive device 200 drives the catheter control box 300 to move in the direction of the external fixing member 400. The catheter control box 300 drives the catheter 500 to move, so that the catheter 500 gradually enters the human body through the nasal cavity or the oral cavity. As the catheter 500 enters, the main body 10 of the support device 100 performs a compression action to provide real-time support for the catheter 500 and effectively prevent the catheter 500 from bending. When the catheter 500 needs to be withdrawn from the human body, it can also be pulled back by the catheter drive device 200. As the catheter 500 is withdrawn, the main body 10 of the support device 100 performs an extension action to provide real-time support for the catheter 500 and effectively prevent the catheter 500 from bending.

[0090] The technical solution provided in the embodiment of the present application can provide effective and good support for the catheter 500 (for example, a medical endoscope) through the support device 100. During the pushing and withdrawing process of the catheter 500, the support device 100 can be extended and retracted accordingly, effectively preventing the catheter 500 from bending, allowing the user to operate the catheter 500 more easily and adjust the posture of the catheter 500 more, meeting more operational freedom and adapting surgical procedures, and can effectively reduce patient trauma while shortening the operation time.

[0091] The catheter support device 100 provided in the embodiment of the present application is further described in detail below.

[0092] Continue to see Figure 1 and Figure 2 In some achievable embodiments of the present application, one achievable manner of the main body 10 of the support device 100 is that the main body 10 includes two sets of symmetrically arranged scissor-type telescopic mechanisms 11, and the two sets of scissor-type telescopic mechanisms 11 are rotatably connected via a rotating shaft 111 at the corresponding intersection. The support channel is located between the two sets of scissor-type telescopic mechanisms 11. While being able to realize the telescopic function, the scissor-type telescopic mechanism 11 also has the advantages of simple structure, low failure rate, easy manufacturing, installation and maintenance. Moreover, the scissor-type telescopic mechanism 11 has a large telescopic range, which can ensure effective support for the catheter 500 under long strokes. In addition, the scissor-type telescopic mechanism 11 has a relatively high load-bearing capacity, a long service life, is not prone to wear and fatigue damage, and has a low maintenance cost.

[0093] Furthermore, in order to increase the portability of the support device 100, the scissor-type telescopic mechanism 11 includes a plurality of scissor-type rods 114, and at least part of the scissor-type rods 114 has a hollow structure 1141. The material of the support device 100 includes but is not limited to PC (Polycarbonate) material, which has the characteristics of lightness, high-strength elastic coefficient, high impact strength, good fatigue resistance, good heat resistance and cold resistance, excellent dimensional stability and good processing performance. At the same time, the hollow structure 1141 is provided on the scissor-type rods 114, which can effectively reduce the amount of materials and reduce costs while ensuring the structural strength, and can effectively reduce the weight of the support device 100 and improve the overall portability of the support device 100.

[0094] Furthermore, in order to provide a balanced supporting force to the catheter 500, the scissor-type telescopic mechanism 11 has a central symmetry line extending from the first end 101 to the second end 102, and the central symmetry line passes through a plurality of spaced intersections as the central intersection 112. The rotation axis 111 corresponding to the central intersection 112 is the support rotation axis 113, and the support rotation axis 113 has a support through hole 1131, and the plurality of support through holes 1131 form a support channel. The support rotation axis 113 is arranged in the middle position of the main body 10, so that when the catheter 500 is in the support channel, it is also in the middle position of the main body 10 accordingly. Under this arrangement, even if the support device 100 changes its angle, it will not affect the support function of the support device 100 for the catheter 500, so that the catheter 500 can be well and effectively supported.

[0095] Further, in some achievable embodiments of the present application, the support rotating shaft 113 is rotatably connected to the two sets of scissor-type telescopic mechanisms 11 respectively. During the process of pushing and withdrawing the catheter 500, since the catheter 500 is a flexible tube, due to certain factors, such as the catheter 500 is too soft, the user's improper operation, and the end of the catheter 500 is subjected to resistance, the catheter 500 may still be deformed. If the support rotating shaft 113 cannot be fine-tuned accordingly, the catheter 500 may be bent. In the embodiment of the present application, the support rotating shaft 113 is rotatably arranged. When the catheter 500 is likely to be deformed and tends to be deformed, the support rotating shaft 113 will deflect accordingly to offset the stress of the deformation of the catheter 500, while continuing to provide support for the deformed catheter 500, and can guide the catheter 500 back to the normal pushing track to avoid further bending of the catheter 500.

[0096] In order to better prevent the possibility and tendency of deformation of the catheter 500, a damping structure is arranged between the support rotating shaft 113 and at least one of the two groups of scissors-type telescopic mechanisms 11. While ensuring that the support rotating shaft 113 can rotate, the randomness of rotation of the support rotating shaft 113 is reduced, thereby better supporting the catheter 500.

[0097] Furthermore, combined with Figure 1 and Figure 2 , see Figure 4 In order to make it easier for the catheter 500 to enter the support channel, in some feasible embodiments of the present application, the projection structure of the support rotating shaft 113 is an ellipse along the direction from one set of scissor-type telescopic mechanisms 11 to another set of scissor-type telescopic mechanisms 11. When the main body 10 is in a compressed state, the support through holes 1131 on the multiple support rotating shafts 113 can be automatically aligned concentrically. When no catheter 500 enters the support channel, that is, the support device 100 is not used, and the catheter 500 does not enter the support through hole 1131 of the support rotating shaft 113, the movement, placement, storage, etc. of the support device 100 may cause each support rotating shaft 113 to rotate to a different direction, resulting in each support through hole 1131 not being concentrically aligned. When used next time, it will be very troublesome and time-consuming to assemble the catheter 500. In the embodiment of the present application, based on the structural setting of the support rotating shaft 113, after the main body 10 is compressed, the length of the entire support device 100 becomes shorter, and at the same time, the support through holes 1131 on the multiple support rotating shafts 113 are automatically concentrically aligned, which can facilitate the insertion of the catheter 500, making the assembly between the catheter 500 and the support device 100 more convenient and effectively reducing the assembly time.

[0098] In some practicable embodiments of the present application, in order to facilitate the connection between the support device 100 and an external device, such as facilitating the connection with the catheter control box 300 and the external fixing member 400. One practicable arrangement of the first quick connector 20 and the second quick connector 30 is to combine Figure 1 and Figure 2 , see Figure 4 The first quick connector 20 is connected to the support rotation shaft 113 located on the first end 101. The first quick connector 20 can move with the support rotation shaft 113. At the same time, the first quick connector 20 can also rotate relative to the support rotation shaft 113 along the circumferential direction of the first quick connector 20. Figure 4 The arrow A in the figure swings along with the supporting rotating shaft 113 connected thereto, and the first quick connector 20 can also rotate along the direction of the arrow B relative to the supporting rotating shaft 113 connected thereto. By changing the angle and posture of the first quick connector 20 itself, the first quick connector 20 can be docked with the external device docked therewith at different angles and positions, such as facilitating the quick connection between the first quick connector 20 and the third quick connector 50 on the catheter control box 300.

[0099] Combination Figure 1 and Figure 2 , see Figure 5 The second quick connector 30 is connected to the support rotation shaft 113 located on the second end 102. The second quick connector 30 can move with the support rotation shaft 113. At the same time, the second quick connector 30 can also rotate relative to the support rotation shaft 113 along the circumferential direction of the second quick connector 30. Figure 5 The arrow C in the figure swings along with the supporting rotating shaft 113 connected thereto, and the second quick connector 30 can also rotate along the direction of the arrow D relative to the supporting rotating shaft 113 connected thereto. By changing the angle and posture of the second quick connector 30 itself, the second quick connector 30 can be docked with the external device docked therewith at different angles and positions, such as facilitating the quick connection between the second quick connector 30 and the fourth quick connector 60 on the external fixing member 400.

[0100] Continue to combine Figure 1 and Figure 2 , see Figure 4 In some achievable embodiments of the present application, one achievable manner of the first quick connector 20 is that the first quick connector 20 includes a first straight cylinder section 21 and a first conical cylinder section 22, the first conical cylinder section 22 is connected to the first straight cylinder section 21 through the large mouth end, and the first conical cylinder section 22 is connected to the first end 101 through the small mouth end. A first quick-insert locking structure 211 and a foolproof structure 212 are provided on the first straight cylinder section 21. The first quick connector 20 can further provide support for the catheter 500 through the first straight cylinder section 21, and provide a certain length of connection stroke for the third quick connector 50 to ensure connection stability. The first quick connector 20 can further guide the catheter 500 into the support channel through the first conical cylinder section 22, which facilitates the assembly between the support device 100 and the catheter 500 and improves the assembly efficiency.

[0101] The foolproof structure 212 can improve the connection accuracy between the first quick connector 20 and the third quick connector 50, and the first quick-insert locking structure 211 can make the connection between the first quick connector 20 and the third quick connector 50 more stable, avoiding separation during movement, ensuring the stability of the entire support system, and thus avoiding the occurrence of bending of the catheter 500.

[0102] Continue to see Figure 4One possible implementation of the first quick-insert locking structure 211 and the fool-proofing structure 212 is that the first quick-insert locking structure 211 includes a locking hole extending along the circumferential direction of the first straight tube section 21. The fool-proofing structure 212 includes a fool-proofing groove extending along the axial direction of the first straight tube section 21 and protruding from the inner wall of the first straight tube section 21 to the outer wall. Accordingly, in order to cooperate with the first quick-insert locking structure 211 and the fool-proofing structure 212, a locking protrusion used in conjunction with the locking hole is provided on the third quick connector 50. After the third quick connector 50 extends the locking protrusion into the first quick connector 20 through the fool-proofing groove, the first quick connector 20 and / or the third quick connector 50 are rotated to complete the docking of the first quick connector 20 and the third quick connector 50. Through the connection between the locking hole and the locking protrusion, the first quick connector 20 and the third quick connector 50 can be firmly connected.

[0103] Continue to combine Figure 1 and Figure 2 , see Figure 5 and Figure 6 In some achievable embodiments of the present application, one achievable manner of the second quick connector 30 is that the second quick connector 30 includes a second straight section 31 and a second conical section 32, the second conical section 32 is connected to the second straight section 31 through the large end, and the second conical section 32 is connected to the second end 102 through the small end. A second quick-insert locking structure 311 is provided on the second straight section 31. The second quick connector 30 can further provide support for the catheter 500 through the second straight section 31, and it is more convenient for the catheter 500 to extend out of the support channel. The second quick connector 30 can further guide the catheter 500 to extend out of the support channel through the second conical section 32. The second quick-insert locking structure 311 can make the connection between the second quick connector 30 and the fourth quick connector 60 more stable, avoid separation during movement, ensure the stability of the entire support system, and further ensure that the catheter 500 can accurately move along a predetermined direction.

[0104] Continue to see Figure 5 and 6 One possible implementation of the second quick-insert locking structure 311 is that the second quick-insert locking structure 311 includes a plug-in barrel 3111 and a latch assembly 3112 disposed on the side wall of the plug-in barrel 3111, and the second quick-insert locking structure 311 is disposed at one end of the second straight barrel section 31 facing away from the second conical barrel section 32 through the plug-in barrel 3111. The latch assembly 3112 can partially extend into the plug-in barrel 3111. Accordingly, in order to cooperate with the plug-in barrel 3111 and the latch assembly 3112, a latch hole 601 used in cooperation with the latch assembly 3112 is provided on the fourth quick connector 60. When the fourth quick connector 60 extends into the plug-in barrel 3111, the fourth quick connector 60 can drive the latch assembly 3112 to cooperate with the latch hole 601 to perform a locking action, that is, the second quick connector 30 and the fourth quick connector 60 are connected.

[0105] See also Figure 6 and 7 In order to further improve the connection accuracy between the second quick connector 30 and the fourth quick connector 60, a first positioning plane 3113 is provided on the inner wall of the plug cylinder 3111 corresponding to the latch assembly 3112, and a second positioning plane 603 is provided on the side of the fourth quick connector 60 facing the latch assembly 3112. The first positioning plane 3113 and the second positioning plane 603 can improve the connection accuracy and prevent the second quick connector 30 and the fourth quick connector 60 from rotating in the circumferential direction, thereby making the connection between the second quick connector 30 and the fourth quick connector 60 more stable, preventing them from being separated during movement, and ensuring the stability of the entire support system.

[0106] Continue to see Figure 6 In some achievable embodiments of the present application, one achievable manner of the latch assembly 3112 is that the latch assembly 3112 includes a latch seat 3114, a latch rod (not shown in the figure) and an elastic member (not shown in the figure). The latch seat 3114 is fixedly disposed on the plug-in barrel 3111. The latch rod is movably connected to the latch seat 3114 and can partially extend into the plug-in barrel 3111. The elastic member is disposed in the latch seat 3114 and is respectively connected to the latch seat 3114 and the latch rod. When the fourth quick connector 60 does not extend into the plug-in barrel 3111, under the action of the elastic member, a portion of the latch rod extends into the plug-in barrel 3111, and a certain gap exists between the end of the latch rod and the inner wall of the plug-in barrel 3111. When the fourth quick connector 60 is inserted into the plug-in barrel 3111, the fourth quick connector 60 can be inserted into the above-mentioned gap, and as the fourth quick connector 60 is inserted, the fourth quick connector 60 pushes up the latch rod, thereby driving the latch rod to move out of the latch seat 3114, and the elastic member is deformed to provide a rebound preload force for the latch rod. The fourth quick connector 60 continues to move into the plug-in barrel 3111, and when it moves to the position corresponding to the latch hole 601 and the latch rod, under the action of the elastic member, the latch rod partially rebounds into the plug-in barrel 3111 and the latch hole 601, completing the locking action between the fourth quick connector 60 and the latch assembly 3112, and completing the docking of the second quick connector 30 and the fourth quick connector 60.

[0107] When the second quick connector 30 needs to be separated from the fourth quick connector 60, the latch rod can be moved, such as by pulling the latch rod open by hand, so that the latch rod moves relatively and moves out of the plug-in tube 3111 and the latch hole 601. At this time, the fourth quick connector 60 can be moved out of the plug-in tube 3111, and the second quick connector 30 and the fourth quick connector 60 can be separated.

[0108] Furthermore, one possible implementation of the latch rod is that the latch rod includes a rod body (not shown) and a rod cap 3115, the rod cap 3115 is disposed at one end of the rod body, the rod body can partially pass through the latch seat 3114 and extend into the plug barrel 3111, and the rod cap 3115 is limited to the end of the latch seat 3114 facing away from the plug barrel 3111. The rod cap 3115 can limit the displacement of the rod body, and it is also convenient for the user to release the locking state of the latch assembly 3112 through the rod cap 3115.

[0109] To further ensure the locking stability of the latch assembly 3112, a first concave-convex positioning structure 3116 is provided on the side of the rod cap 3115 facing the latch seat 3114, and a second concave-convex positioning structure 3117 used in conjunction with the first concave-convex positioning structure 3116 is provided on the side of the latch seat 3114 facing the rod cap 3115. When the latch assembly 3112 is in a locked state, the concave-convex parts of the first concave-convex positioning structure 3116 and the second concave-convex positioning structure 3117 can mesh with each other, which can prevent the latch rod from rotating at will and ensure the stability of the latch rod. At the same time, when releasing the locking state of the latch assembly 3112, after pulling out the latch rod, the latch rod can be rotated so that the first concave-convex positioning structure 3116 is in contact with the convex part of the second concave-convex positioning structure. At this time, the elastic member is deformed to provide a rebound pre-tightening force for the latch rod, and the latch rod will not rebound into the plug-in barrel 3111, which can facilitate the fourth quick connector 60 to extend into the plug-in barrel 3111. After the fourth quick connector 60 is extended into the plug-in barrel 3111, the latch rod is rotated to remove the external force, so that under the action of the elastic member, the latch rod partially rebounds into the plug-in barrel 3111 and the latch hole 601, completing the locking action between the fourth quick connector 60 and the latch assembly 3112, and completing the docking of the second quick connector 30 and the fourth quick connector 60.

[0110] Combination Figure 1 and Figure 2 , continue to see Figure 5 and Figure 6 In some achievable embodiments of the present application, the support device 100 further includes a tube orifice seal 40 for sealing the tube orifice of the catheter 500, and the tube orifice seal 40 is disposed on the second end 102. In an application scenario of the support device 100, after the catheter 500 is inserted into the lungs, the tube orifice seal 40 can be used to seal the tube orifice of the catheter 500 to prevent oxygen or anesthetic gas in the lungs from escaping through the catheter 500.

[0111] One possible implementation of the orifice seal 40 is that the orifice seal 40 includes a main body ring 41 and a sealing arm 42. The main body ring 41 is connected to the second end 102 and communicates with the support channel through the inner ring of the main body ring 41. One end of the sealing arm 42 is connected to the main body ring 41, and the other end has a sealing plug 421. The sealing arm 42 can be folded back so that the sealing plug 421 moves to the main body ring 41 to seal the orifice of the catheter 500. When the catheter 500 completes the action of extending into the inner cavity (such as the lungs), the orifice exposed to the outside allows the inner cavity to communicate with the external environment. At this time, the sealing arm 42 can be folded back so that the sealing plug 421 moves to the orifice of the catheter 500 and plugs into the orifice to achieve sealing of the catheter 500. The material of the orifice seal 40 includes but is not limited to soft rubber material, such as rubber material, silicone material, etc., and the structure of the sealing plug 421 includes but is not limited to a conical plug.

[0112] Further, see Figure 5 and Figure 6 In order to facilitate the sealing action of the pipe mouth seal 40, one arrangement of the pipe mouth seal 40 is that the pipe mouth seal 40 is connected to the support rotating shaft 113 located on the second end 102 through the main body ring 41, and the pipe mouth seal 40 and the second quick connector 30 are arranged on opposite sides of the same support rotating shaft 113. The pipe mouth seal 40 can move with the support rotating shaft 113, and the pipe mouth seal 40 can also rotate relative to the support rotating shaft 113 along the circumferential direction of the main body ring 41. The pipe mouth seal 40 can move along the support rotating shaft 113. Figure 5 The arrow C in the figure swings along with the supporting rotating shaft 113 connected thereto, and the nozzle seal 40 can also rotate along the direction of the arrow D relative to the supporting rotating shaft 113 connected thereto, and by changing the angle of the nozzle seal 40 itself, the nozzle seal 40 can seal the catheter 500 at different angles and positions.

[0113] Further, in some achievable embodiments of the present application, the tube mouth seal 40 also includes a positioning arm 43. One end of the positioning arm 43 is connected to the main body ring 41, and the other end has a positioning ring 431. The positioning arm 43 can be folded back to move the positioning ring 431 to the main body ring 41 to position the tube mouth end of the catheter 500. After the catheter 500 completes the action of extending into the inner cavity (such as the lungs), the portion of the catheter 500 exposed to the outside needs to reduce displacement to avoid displacement of the portion of the catheter 500 in the inner cavity. In order to further stabilize the relative position of the catheter 500, the catheter 500 can be fixed by the positioning ring 431 to reduce the random displacement of the external portion of the catheter 500 to ensure the smooth progress of the operation.

[0114] Based on the supporting device 100 provided in the above embodiment of the present application, see Figure 3Accordingly, an embodiment of the present application further provides a support system for a catheter 500, comprising: a support device 100 as described in the above embodiment, wherein the support device 100 can be implemented by the implementation method of the support device 100 in the above embodiment, and related technical features can be referenced and borrowed from each other.

[0115] Furthermore, the support system further includes: a catheter drive device 200, a catheter control box 300 and an external fixing member 400. The catheter control box 300 is drivingly connected to the catheter drive device 200, and the catheter control box 300 has a third quick connector 50 for connecting with the first quick connector 20, and the third quick connector 50 is also used to connect with the catheter 500. The external fixing member 400 is arranged on the catheter drive device 200, and the external fixing member 400 has a fourth quick connector 60 for connecting with the second quick connector 30. Among them, the catheter 500 can enter the support channel through the first quick connector 20 and extend from the second quick connector 30, and the catheter drive device 200 can drive the catheter control box 300 to reciprocate in the direction of the external fixing member 400, so as to drive the catheter 500 to move and drive the main body 10 to perform telescopic action.

[0116] In the embodiment of the present application, the support system includes but is not limited to being used in conjunction with a surgical robot. The support system is assembled on the robotic arm of the surgical robot through a catheter drive device 200, and the catheter drive device 200 can be operated by a control device or manually controlled by a user.

[0117] One use of the support system is that the catheter control box 300 and the external fixing member 400 are respectively arranged at opposite ends of the catheter driving device 200, and the support device 100 is arranged between the catheter control box 300 and the external fixing member 400. The catheter driving device 200 can drive the catheter control box 300 to reciprocate in the direction of the external fixing member 400. The catheter control box 300 has a third quick connector 50 for connecting with the first quick connector 20, and the third quick connector 50 is also used to connect with the catheter 500. The third quick connector 50 is connected to the first quick connector 20, and the catheter 500 can enter the support channel through the first quick connector 20 and extend from the second quick connector 30. The support device 100 supports the catheter 500 through the support channel.

[0118] The external fixing member 400 has a fourth quick connector 60 for connecting with the second quick connector 30, and the fourth quick connector 60 is connected to the second quick connector 30. The external fixing member 400 includes but is not limited to being fixed to the patient's endotracheal cannula, so that the catheter 500 can more easily enter the inner cavity of the human lung.

[0119] Taking the example of pushing the catheter 500 into the lungs, when the catheter 500 needs to be pushed into the human lungs, the catheter driving device 200 drives the catheter control box 300 to move in the direction of the external fixing member 400, and the catheter control box 300 drives the catheter 500 to move, so that the catheter 500 gradually enters the human body through the nasal cavity or the oral cavity. As the catheter 500 enters, the main body 10 of the support device 100 performs a compression action to provide real-time support for the catheter 500, effectively preventing the catheter 500 from bending. When the catheter 500 needs to be withdrawn from the human body, it can also be pulled back by the catheter driving device 200. As the catheter 500 is withdrawn, the main body 10 of the support device 100 performs an extension action to provide real-time support for the catheter 500, effectively preventing the catheter 500 from bending, making it easier for the user to operate the catheter 500, and more convenient to adjust the posture of the catheter 500, meeting more operating freedom and adapting to the surgical procedure requirements, and can effectively reduce patient trauma while shortening the operation time.

[0120] See also Figure 4 In some achievable embodiments of the present application, a locking hole and an anti-idiot groove are provided on the first quick connector 20. The anti-idiot groove can improve the connection accuracy between the first quick connector 20 and the third quick connector 50, and the locking hole can make the connection between the first quick connector 20 and the third quick connector 50 more stable, avoiding separation during movement, ensuring the stability of the entire support system, and thus avoiding the occurrence of bending of the catheter 500. In order to cooperate with the locking hole and the anti-idiot groove, the third quick connector 50 is provided with a locking protrusion used in conjunction with the locking hole. After the third quick connector 50 extends the locking protrusion into the first quick connector 20 through the anti-idiot groove, the first quick connector 20 and / or the third quick connector 50 are rotated to complete the docking of the first quick connector 20 and the third quick connector 50. Through the connection between the locking hole and the locking protrusion, the first quick connector 20 and the third quick connector 50 can be stably connected.

[0121] Further, see Figure 5 and Figure 6 The second quick connector 30 is provided with a plug-in barrel 3111 and a plug-in assembly 3112 disposed on the side wall of the plug-in barrel 3111. Figure 7 and Figure 8 The fourth quick connector 60 is provided with a latch hole 601 used in conjunction with the latch assembly 3112. When the fourth quick connector 60 is inserted into the plug-in barrel 3111, the fourth quick connector 60 can drive the latch assembly 3112 to lock in conjunction with the latch hole 601. The plug-in barrel 3111 and the latch assembly 3112 can make the connection between the second quick connector 30 and the fourth quick connector 60 more stable, avoid separation during movement, ensure the stability of the entire support system, and further ensure that the catheter 500 can accurately move along a predetermined direction.

[0122] Continue to see Figure 7 In order to enable the fourth quick connector 60 to more smoothly drive the latch assembly 3112 to perform a locking action, in an achievable embodiment, a guide slope 602 is provided on one end of the fourth quick connector 60 that faces the second quick connector 30. When the fourth quick connector 60 does not extend into the plug-in barrel 3111, under the action of the elastic member, part of the latch rod extends into the plug-in barrel 3111, and a certain gap exists between the end of the latch rod and the inner wall of the plug-in barrel 3111. When the fourth quick connector 60 extends into the plug-in barrel 3111, the fourth quick connector 60 first extends into the above gap through the narrower part of the guide slope 602, and as the fourth quick connector 60 extends, the fourth quick connector 60 gradually lifts the latch rod through the guide slope 602, thereby driving the latch rod to move out of the latch seat 3114, and at this time, the elastic member is deformed to provide a rebound preload force for the latch rod. The fourth quick connector 60 continues to move into the plug-in tube 3111. When it moves to the position where the latch hole 601 corresponds to the latch rod, the latch rod partially rebounds into the plug-in tube 3111 and the latch hole 601 under the action of the elastic member, completing the locking action between the fourth quick connector 60 and the latch assembly 3112, and completing the docking between the second quick connector 30 and the fourth quick connector 60.

[0123] Furthermore, in order to further improve the connection accuracy between the second quick connector 30 and the fourth quick connector 60, a first positioning plane 3113 is provided on the inner wall of the plug cylinder 3111 corresponding to the latch assembly 3112, and a second positioning plane 603 is provided on the side of the fourth quick connector 60 facing the latch assembly 3112. The first positioning plane 3113 and the second positioning plane 603 can improve the connection accuracy and prevent the second quick connector 30 and the fourth quick connector 60 from rotating in the circumferential direction, thereby making the connection between the second quick connector 30 and the fourth quick connector 60 more stable, preventing separation during movement, and ensuring the stability of the entire support system.

[0124] Continue to see Figure 7 and Figure 8 In order to better realize the fixing function of the external fixing member 400, in some achievable embodiments of the present application, the external fixing member 400 is also provided with a clamping claw 61 and a fixing arm 62. The clamping claw 61 is respectively connected to the fourth quick connector 60 and the fixing arm 62, and the clamping claw 61 includes at least two symmetrically arranged arc-shaped claws, and the two arc-shaped claws form a clamping space 611. The external fixing member 400 includes but is not limited to being used for fixing with the patient's endotracheal tube, so as to make it easier for the catheter 500 to enter the inner cavity such as the lungs of the human body. The clamping space 611 can be well adapted to the outer contour of the endotracheal tube, and the external fixing member 400 and the endotracheal tube can be quickly disassembled and assembled through the clamping claw 61, without the need for additional disassembly and assembly tools and disassembly and assembly accessories, and the disassembly and assembly process is simple and convenient.

[0125] The fixed arm 62 includes an arm rod 621 and a fixing head 622. One end of the arm rod 621 is connected to the clamping claw 61, and the other end is connected to the fixing head 622. The fixing head 622 is connected to the catheter driving device 200. The external fixing member 400 is fixed to the driving unit 70 through the fixing head 622, and the arm rod 621 provides support for the clamping claw 61 and the fourth quick connector 60 to ensure that the position of the external fixing member 400 is relatively fixed, so that the external fixing member 400 provides support for the supporting device 100 through the fourth quick connector 60.

[0126] Further, see Figure 8 The fixing head 622 is a non-rotating structure. The fixing head 622 includes but is not limited to a rectangular, triangular, polygonal, etc. The fixing head 622 with a non-rotating structure can ensure the relative position of the external fixing member 400 is stable, avoiding relative displacement such as rotation, thereby ensuring the stability of the support device 100 and the entire support system, and thereby ensuring that the catheter 500 can accurately move along a predetermined direction.

[0127] Combination Figure 3 , see Fig. 9 In some achievable embodiments of the present application, one achievable manner of the catheter driving device 200 is that the catheter driving device 200 includes a driving unit 70 and a guide rail frame 71. The driving unit 70 is disposed on the guide rail frame 71, and the driving unit 70 is connected to the catheter control box 300, and can drive the catheter control box 300 to move along the guide rail frame 71. The guide rail frame 71 has a fixing groove 711 at one end away from the driving unit 70, and the guide rail frame 71 is connected to the external fixing member 400 through the fixing groove 711. The driving unit 70 includes a motor and a transmission assembly, and the motor can be operated by a control device or manually controlled by a user. The driving unit 70 can drive the catheter control box 300 to move along the guide rail frame 71, such as moving forward or backward along the extension direction of the guide rail frame 71, and the guide rail frame 71 can make the movement of the catheter control box 300 more stable.

[0128] The fixing groove 711 on the guide rail frame 71 has the function of fixing the external fixing member 400 to ensure the relative position stability of the external fixing member 400. In some embodiments of the present application, the fixing head 622 is a non-rotating structure, and accordingly, the fixing groove 711 is a structure that matches the shape of the fixing head 622.

[0129] To sum up, the technical solution provided in the embodiment of the present application can provide effective and good support for the catheter 500 (medical endoscope) through the support device 100. During the pushing and withdrawal process of the catheter 500, the support device 100 can be extended and retracted accordingly, effectively preventing the catheter 500 from bending, allowing the user to operate the catheter 500 more easily and adjust the posture of the catheter 500 more, meeting more operating freedom and adapting surgical procedures, and can effectively reduce patient trauma while shortening the operation time.
