Abstract
Description

For example, pulmonary interventional surgery using surgical robots combined with flexible catheters has become an increasingly popular treatment method.

Obviously, the described embodiments are part of the embodiments of the present application, not all of them.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the embodiments of the present application.

[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 structural diagram 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] To address the technical problems of the prior art, the present invention provides a catheter support device 100, comprising 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 disposed opposite each other. The main body 10 is capable of telescoping from the first end 101 to the second end 102. The main body 10 defines a support channel extending from the first end 101 to the second end 102. The support device 100 supports 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] Combine Figure 1 and Figure 2 , see Figure 3 One way to use the support device 100 is to use it in conjunction with a catheter drive device 200, a catheter control box 300, and an external fixture 400 to form a support system. The catheter control box 300 and the external fixture 400 are respectively disposed at opposite ends of the catheter drive device 200, and the support device 100 is disposed between the catheter control box 300 and the external fixture 400. The catheter drive device 200 can drive the catheter control box 300 to reciprocate toward the external fixture 400.
[0087] The catheter control box 300 includes a third quick connector 50 for mating with the first quick connector 20. The third quick connector 50 is also used to connect to the catheter 500. The third quick connector 50 is docked with the first quick connector 20, allowing the catheter 500 to 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 embodiments of the present application, the catheter 500 includes, but is not limited to, medical endoscopes, surgical catheters 500, navigation scopes, sheaths, and other medical hoses that can be used to enter the body cavities of humans and animals. In the embodiments of the present application, the catheter 500 is used as an example for illustration, not as a specific limitation, and this does not constitute a disadvantageous limitation of the present application.
[0088] The external fixing member 400 includes a fourth quick connector 60 for mating with the second quick connector 30. The fourth quick connector 60 is docked with the second quick connector 30. The external fixing member 400 includes, but is not limited to, securing the patient's endotracheal tube, thereby facilitating the catheter 500's entry into the lungs or other cavities of the human body.
[0089] The catheter drive device 200 is connected to the robotic 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 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 (such as 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, making it easier for the user to operate the catheter 500 and more convenient to adjust the posture of the catheter 500, meeting more operational freedom and adapting to surgical procedures, and can effectively reduce patient trauma while shortening the operation time.
[0091] The catheter support device 100 provided in an embodiment of the present application is further described in detail below.
[0092] Continue to see Figure 1 and Figure 2 In some feasible embodiments of the present application, one feasible way for 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 through the 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 low maintenance costs.
[0093] Furthermore, to increase the portability of the support device 100, the scissor-type telescopic mechanism 11 includes a plurality of scissor-type rods 114, at least some of which have a hollow structure 1141. The materials used to manufacture the support device 100 include, but are not limited to, PC (Polycarbonate) material. PC material has the characteristics of being lightweight, having a high-strength elastic modulus, high impact strength, excellent fatigue resistance, good heat and cold resistance, excellent dimensional stability, and good processing properties. At the same time, the hollow structure 1141 provided on the scissor-type rods 114 can effectively reduce material usage and costs while ensuring structural strength, and can effectively reduce the weight of the support device 100, thereby improving the overall portability of the support device 100.
[0094] Furthermore, to provide balanced support for 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. The central symmetry line passes through multiple, spaced-apart intersections, which serve as central intersections 112. A rotation axis 111, corresponding to central intersection 112, serves as a support rotation axis 113. The support rotation axis 113 has a support through-hole 1131, and the multiple support through-holes 1131 form a support channel. The support rotation axis 113 is positioned in the middle of the main body 10, so that when the catheter 500 is within the support channel, it is also positioned in the middle of the main body 10. With this arrangement, even if the support device 100 changes its angle, it does not affect its support function for the catheter 500, ensuring that the catheter 500 is consistently and effectively supported.
[0095] Furthermore, in some feasible embodiments of the present application, the support rotating shaft 113 is rotatably connected to the two sets of scissor-type telescopic mechanisms 11. During the pushing and retracting process of the catheter 500, since the catheter 500 is a flexible tube, due to certain factors, such as the catheter 500 being too soft, improper operation by the user, resistance at the end of the catheter 500, etc., the catheter 500 may still be deformed. If the support rotating shaft 113 cannot be fine-tuned accordingly, the catheter 500 may bend. 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 guiding the catheter 500 back to the normal pushing track to prevent the catheter 500 from further bending.
[0096] In order to better prevent the possibility and tendency of deformation of the catheter 500, a damping structure is set 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 the rotation of the support rotating shaft 113 is reduced, thereby better providing support for the catheter 500.
[0097] Further, 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 along the direction from one set of scissors-type telescopic mechanisms 11 to another set of scissors-type telescopic mechanisms 11 is elliptical. 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-holes 1131 of the support rotating shaft 113, the movement, placement, storage, etc. of the support device 100 may cause the various support rotating shafts 113 to rotate in different directions, resulting in the various support through-holes 1131 not being concentrically aligned. When used next time, it will be very troublesome to assemble the catheter 500, which is a waste of time. 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 achievable 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, a achievable 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 along 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 Arrow A in the figure swings along with the supporting rotating shaft 113 connected thereto, and simultaneously, the first quick connector 20 can also rotate relative to the supporting rotating shaft 113 connected thereto in the direction of arrow B. By changing the angle and posture of the first quick connector 20 itself, the first quick connector 20 can be easily connected to the external device at different angles and positions, for example, the first quick connector 20 can be quickly connected to the third quick connector 50 on the catheter control box 300.
[0099] Combine 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 along 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 Arrow C in FIG. 1 swings along with the supporting rotating shaft 113 to which it is connected. Simultaneously, the second quick connector 30 can also rotate relative to the supporting rotating shaft 113 to which it is connected in the direction of arrow D. By changing the angle and posture of the second quick connector 30, the second quick connector 30 can be easily connected to the external device at different angles and positions, for example, 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 feasible embodiments of the present application, one feasible implementation of the first quick connector 20 is that the first quick connector 20 includes a first straight section 21 and a first conical section 22. The first conical section 22 is connected to the first straight section 21 via the large end, and the first conical section 22 is connected to the first end 101 via the small end. The first straight section 21 is provided with a first quick-insert locking structure 211 and an anti-fool structure 212. The first quick connector 20 can further provide support for the conduit 500 through the first straight section 21 and provide a certain length of connection travel for the third quick connector 50 to ensure connection stability. The first quick connector 20 can further guide the conduit 500 into the support channel through the first conical section 22, facilitating assembly between the support device 100 and the conduit 500 and improving 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 preventing the catheter 500 from bending.
[0102] Continue to see Figure 4One possible implementation of the first quick-insert locking structure 211 and the foolproofing structure 212 is that the first quick-insert locking structure 211 includes a locking hole extending circumferentially along the first straight cylindrical section 21. The foolproofing structure 212 includes a foolproofing groove extending axially along the first straight cylindrical section 21 and protruding from the inner wall toward the outer wall of the first straight cylindrical section 21. Accordingly, to cooperate with the first quick-insert locking structure 211 and the foolproofing structure 212, the third quick connector 50 is provided with a locking protrusion that cooperates with the locking hole. After the third quick connector 50 extends the locking protrusion into the first quick connector 20 through the foolproofing 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. The connection between the locking hole and the locking protrusion ensures a secure connection between the first quick connector 20 and the third quick connector 50.
[0103] Continue to combine Figure 1 and Figure 2 , see Figure 5 and Figure 6 In some feasible embodiments of the present application, one feasible implementation of the second quick connector 30 is that the second quick connector 30 includes a second straight section 31 and a second tapered section 32, wherein the second tapered section 32 is connected to the second straight section 31 via the large end, and the second tapered section 32 is connected to the second end 102 via 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 more conveniently extend the catheter 500 out of the support channel. The second quick connector 30 can further guide the catheter 500 out of the support channel through the second tapered 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, prevent detachment during movement, ensure the stability of the entire support system, and thus ensure that the catheter 500 can accurately move along the 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 cylinder 3111 and a latch assembly 3112 disposed on a side wall of the plug-in cylinder 3111. The second quick-insert locking structure 311 is disposed at an end of the second straight cylinder section 31 facing away from the second conical cylinder section 32 through the plug-in cylinder 3111. The latch assembly 3112 can partially extend into the plug-in cylinder 3111. Accordingly, to cooperate with the plug-in cylinder 3111 and the latch assembly 3112, the fourth quick connector 60 is provided with a latch hole 601 for use with the latch assembly 3112. When the fourth quick connector 60 extends into the plug-in cylinder 3111, the fourth quick connector 60 can drive the latch assembly 3112 to cooperate with the latch hole 601 to perform a locking action, thereby completing the docking of the second quick connector 30 and the fourth quick connector 60.
[0105] See also Figure 6 and 7 To further enhance the connection precision between the second quick connector 30 and the fourth quick connector 60, a first positioning flat 3113 is provided on the inner wall of the plug barrel 3111, corresponding to the latch assembly 3112. A second positioning flat 603 is provided on the side of the fourth quick connector 60 facing the latch assembly 3112. The first and second positioning flats 3113 and 603 not only enhance connection precision but also prevent circumferential rotation between the second and fourth quick connectors 30 and 60, thereby further stabilizing the connection and preventing disengagement during movement, thereby ensuring the stability of the entire support system.
[0106] Continue to see Figure 6 In some feasible embodiments of the present application, one feasible way of implementing 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 arranged on the plug-in tube 3111. The latch rod is movably connected to the latch seat 3114 and can partially extend into the plug-in tube 3111. The elastic member is arranged in the latch seat 3114 and is respectively connected to the latch seat 3114 and the latch rod. When the fourth quick connector 60 is not extended into the plug-in tube 3111, under the action of the elastic member, part of the latch rod extends into the plug-in tube 3111, and there is a certain gap between the end of the latch rod and the inner wall of the plug-in tube 3111. When the fourth quick connector 60 is inserted into the plug barrel 3111, it can be inserted into the aforementioned gap. As the fourth quick connector 60 is inserted, it lifts the latch rod, thereby driving the latch rod out of the latch seat 3114. At this point, the elastic member deforms, providing a rebound preload force on the latch rod. The fourth quick connector 60 continues to move into the plug barrel 3111. When it reaches the position where the latch hole 601 aligns with the latch rod, the elastic member causes the latch rod to partially rebound into the plug 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 between the second quick connector 30 and the fourth quick connector 60.
[0107] When the second quick connector 30 and the fourth quick connector 60 need to be separated, the latch rod can be moved, for example, by manually pulling the latch rod, so that the latch rod moves relative to the insertion barrel 3111 and the latch hole 601. At this time, the fourth quick connector 60 can be removed from the insertion barrel 3111, and the second quick connector 30 and the fourth quick connector 60 can be separated.
[0108] Furthermore, one possible implementation of the latch lever is as follows: the latch lever 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 insertion tube 3111. The rod cap 3115 is restrained at the end of the latch seat 3114 facing away from the insertion tube 3111. The rod cap 3115 limits the displacement of the rod body and also facilitates the user to release the locked state of the latch assembly 3112 by using the rod cap 3115.
[0109] To further ensure the locking stability of latch assembly 3112, a first concave-convex positioning structure 3116 is provided on the side of rod cap 3115 facing latch seat 3114, and a second concave-convex positioning structure 3117 is provided on the side of latch seat 3114 facing rod cap 3115, which cooperates with first concave-convex positioning structure 3116. When latch assembly 3112 is locked, the concave and convex portions of first concave-convex positioning structure 3116 and second concave-convex positioning structure 3117 engage with each other, preventing the latch rod from rotating freely and ensuring its stability. At the same time, to release the locked 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 aligns with the raised portion of the second concave-convex positioning structure. At this time, the elastic member deforms to provide a rebound preload force to the latch rod, and the latch rod will not rebound into the plug barrel 3111, facilitating the insertion of the fourth quick connector 60 into the plug barrel 3111. After the fourth quick connector 60 is inserted into the plug barrel 3111, the latch rod is rotated to remove the external force. Under the action of the elastic member, the latch rod partially rebounds into the plug 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 with the fourth quick connector 60.
[0110] Combine Figure 1 and Figure 2 , continue to see Figure 5 and Figure 6 In some possible embodiments of the present application, the support device 100 further includes a nozzle seal 40 for sealing the nozzle of the catheter 500. The nozzle seal 40 is disposed on the second end 102. In one application scenario of the support device 100, after the catheter 500 is inserted into the lungs, the nozzle seal 40 can be used to seal the nozzle 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 as follows: 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 to allow the sealing plug 421 to move to the main body ring 41 and seal the orifice of the catheter 500. After the catheter 500 is inserted into an internal cavity (such as the lungs), the exposed orifice allows the internal cavity to communicate with the external environment. At this time, the sealing arm 42 can be folded back to allow the sealing plug 421 to move to the orifice of the catheter 500 and plug into the orifice, thereby sealing the catheter 500. The material of the orifice seal 40 includes, but is not limited to, a soft rubber material such as rubber or silicone. The structure of the sealing plug 421 includes, but is not limited to, a tapered plug.
[0112] Further, see Figure 5 and Figure 6 In order to facilitate the sealing action of the nozzle seal 40, one arrangement of the nozzle seal 40 is that the nozzle seal 40 is connected to the support rotating shaft 113 located on the second end 102 through the main body ring 41, and the nozzle seal 40 and the second quick connector 30 are respectively arranged on opposite sides of the same support rotating shaft 113. The nozzle seal 40 can move along the support rotating shaft 113, and at the same time, the nozzle seal 40 can also rotate relative to the support rotating shaft 113 along the circumferential direction of the main body ring 41. The nozzle 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 at the same time, the nozzle seal 40 can also rotate relative to the supporting rotating shaft 113 connected thereto along the direction of the arrow D. 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] Furthermore, in some feasible embodiments of the present application, the nozzle 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 nozzle 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 also 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 through 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] The support system further includes a catheter drive device 200, a catheter control box 300, and an external fixture 400. The catheter control box 300 is drivingly connected to the catheter drive device 200. The catheter control box 300 has a third quick connector 50 for mating with the first quick connector 20. The third quick connector 50 is also used to connect to the catheter 500. The external fixture 400 is disposed on the catheter drive device 200 and has a fourth quick connector 60 for mating with the second quick connector 30. The catheter 500 can enter the support channel through the first quick connector 20 and extend from the second quick connector 30. The catheter drive device 200 can drive the catheter control box 300 to reciprocate toward the external fixture 400, thereby driving the catheter 500 to move and the main body 10 to extend and retract.
[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 manual control by a user.
[0117] In one embodiment of the support system, the catheter control box 300 and the external fixture 400 are positioned at opposite ends of the catheter drive device 200, with the support device 100 positioned between them. The catheter drive device 200 can drive the catheter control box 300 to reciprocate toward the external fixture 400. The catheter control box 300 includes a third quick connector 50 for mating with the first quick connector 20. The third quick connector 50 is also configured to connect to the catheter 500. The third quick connector 50 interfaces with the first quick connector 20, allowing the catheter 500 to 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 includes a fourth quick connector 60 for mating with the second quick connector 30. The fourth quick connector 60 is docked with the second quick connector 30. The external fixing member 400 includes, but is not limited to, securing the patient's endotracheal tube, thereby facilitating the catheter 500's entry into the lungs or other cavities of the human body.
[0119] Taking the example of inserting the catheter 500 into the lungs, when the catheter 500 needs to be inserted into the human lungs, the catheter drive device 200 drives the catheter control box 300 to move toward the direction of the external fixing member 400. The catheter control box 300 drives the catheter 500 to move, causing the catheter 500 to gradually enter the human body through the nasal cavity or oral cavity. As the catheter 500 enters the human body, the main body 10 of the support device 100 compresses 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, the catheter drive device 200 can also be used to pull it back. As the catheter 500 is withdrawn, the main body 10 of the support device 100 extends to provide real-time support for the catheter 500 and effectively prevent the catheter 500 from bending. This makes it easier for the user to operate the catheter 500 and adjust the catheter 500's posture, meeting greater operational freedom and adapting to surgical procedures. This can effectively reduce patient trauma while shortening surgical time.
[0120] See also Figure 4 In some feasible embodiments of the present application, the first quick connector 20 is provided with a locking hole and an anti-muck groove. The anti-muck groove improves the connection accuracy between the first quick connector 20 and the third quick connector 50. The locking hole further stabilizes the connection between the first quick connector 20 and the third quick connector 50, preventing disengagement during movement, ensuring the stability of the entire support system, and thus preventing the catheter 500 from bending. To cooperate with the locking hole and anti-muck groove, the third quick connector 50 is provided with a locking protrusion that cooperates with the locking hole. After the third quick connector 50 extends the locking protrusion into the first quick connector 20 through the anti-muck groove, the first quick connector 20 and / or the third quick connector 50 are rotated to complete the connection between the first quick connector 20 and the third quick connector 50. The connection between the locking hole and the locking protrusion ensures a stable connection between the first quick connector 20 and the third quick connector 50.
[0121] Further, see Figure 5 and Figure 6 The second quick connector 30 is provided with a plug-in barrel 3111 and a latch 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 for use with the latch assembly 3112. When the fourth quick connector 60 is inserted into the insertion barrel 3111, the fourth quick connector 60 drives the latch assembly 3112 to engage the latch hole 601 for locking. The insertion barrel 3111 and latch assembly 3112 further secure the connection between the second quick connector 30 and the fourth quick connector 60, preventing disengagement during movement and ensuring the stability of the entire support system, thereby ensuring that the catheter 500 can accurately move in the intended direction.
[0122] Continue to see Figure 7 To enable the fourth quick connector 60 to more smoothly drive the latch assembly 3112 to lock, in one feasible embodiment, a guide ramp 602 is provided on the end of the fourth quick connector 60 facing the second quick connector 30. When the fourth quick connector 60 is not inserted into the insertion barrel 3111, the elastic member acts to partially insert the latch rod into the insertion barrel 3111, leaving a gap between the end of the latch rod and the inner wall of the insertion barrel 3111. When the fourth quick connector 60 is inserted into the insertion barrel 3111, the fourth quick connector 60 first enters the gap through the narrower portion of the guide ramp 602. As the fourth quick connector 60 is inserted, the guide ramp 602 gradually lifts the latch rod, thereby driving the latch rod out of the latch seat 3114. At this time, the elastic member deforms, providing a rebound preload force on the latch rod. The fourth quick connector 60 continues to move into the plug barrel 3111. When it moves to the position where the latch hole 601 corresponds to the latch rod, the elastic member causes the latch rod to partially rebound into the plug 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 between the second quick connector 30 and the fourth quick connector 60.
[0123] Furthermore, to further enhance the connection precision between the second quick connector 30 and the fourth quick connector 60, a first positioning flat 3113 is provided on the inner wall of the plug barrel 3111 corresponding to the latch assembly 3112, and a second positioning flat 603 is provided on the side of the fourth quick connector 60 facing the latch assembly 3112. The first and second positioning flats 3113 and 603 not only enhance connection precision but also prevent circumferential rotation between the second quick connector 30 and the fourth quick connector 60, thereby further stabilizing the connection and preventing disengagement during movement, thereby 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 feasible embodiments of the present application, the external fixing member 400 is further provided with a clamping claw 61 and a fixing arm 62. The clamping claw 61 is connected to the fourth quick connector 60 and the fixing arm 62 respectively. 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, thereby making it easier for the catheter 500 to enter the human body's lungs and other internal cavities. The clamping space 611 can be well adapted to the outer contour of the endotracheal tube. The clamping claw 61 can quickly complete the disassembly and assembly between the external fixing member 400 and the endotracheal tube without the need for additional disassembly and assembly tools and disassembly accessories. 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 engaging claw 61, and the other end is connected to the fixing head 622. The fixing head 622 is connected to the catheter drive device 200. The fixing head 622 secures the external fixing member 400 to the drive unit 70. The arm rod 621 also provides support for the engaging claw 61 and the fourth quick connector 60, ensuring that the external fixing member 400 is relatively fixed in position. Furthermore, the external fixing member 400 provides support for the support device 100 via 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 non-rotating structure of the fixing head 622 ensures the relative position of the external fixing member 400 is stable, preventing relative displacement such as rotation, thereby ensuring the stability of the support device 100 and the entire support system, and further ensuring that the catheter 500 can accurately move along the predetermined direction.
[0127] Combine Figure 3 , see Figure 9 In some possible embodiments of the present application, one possible implementation of the catheter drive device 200 is as follows: the catheter drive device 200 includes a drive unit 70 and a guide rail frame 71. The drive unit 70 is disposed on the guide rail frame 71, connected to the catheter control box 300, and capable of driving the catheter control box 300 to move along the guide rail frame 71. The guide rail frame 71 has a fixing slot 711 at one end away from the drive unit 70, and the guide rail frame 71 is connected to the external fixing member 400 via the fixing slot 711. The drive unit 70 includes a motor and a transmission assembly. The motor can be operated by a control device or manually controlled by a user. The drive unit 70 can drive the catheter control box 300 to move along the guide rail frame 71, such as forward or backward along the extension direction of the guide rail frame 71. The guide rail frame 71 can ensure smoother movement of the catheter control box 300.
[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, making it easier for the user to operate the catheter 500 and more convenient to adjust the posture of the catheter 500, meeting more operational freedom and adapting surgical procedures, and can effectively reduce patient trauma while shortening the operation time.
