DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0035] An embodiment of the present utility model discloses a docking device for interventional treatment, in particular, a docking device that can assist medical personnel in conveniently completing the operation of passing a guide wire 100 through a balloon catheter 200, thereby saving medical personnel time and effort when performing the operation of passing a guide wire 100 through a balloon catheter 200.

[0036] like Figure 1 As shown in FIG, it shows the general structure of the exemplary docking device disclosed in this embodiment. Figure 1 In the dock shown, the dock may include a positioning assembly 10 and a guide assembly 20 .

[0037] In this embodiment, the positioning assembly 10 is used to position the balloon catheter 200 so that the balloon catheter 200 can remain stationary when the guide wire 100 is passed through the balloon catheter 200. The balloon catheter 200 has a head end and a tail end.

[0038] In order to simplify the process of positioning the balloon catheter 200 as much as possible, Figure 1 As shown, the positioning assembly 10 may include a positioning platform 11. The positioning platform 11 may have a generally rectangular structure and may be provided with a positioning groove 12 that matches the shape of the balloon catheter 200. The positioning groove 12 may be provided on the top of the positioning platform 11.

[0039] Thus, when the balloon catheter 200 needs to be positioned, refer to Figure 5 As shown, the balloon catheter 200 only needs to be inserted into the positioning groove 12 on the positioning platform 11 to achieve temporary fixation of the balloon catheter 200. Of course, when the guidewire 100 is subsequently passed through the balloon catheter 200, the medical staff can also appropriately press the balloon catheter 200 inserted into the positioning groove 12 to ensure that the balloon catheter 200 does not move during the process of the guidewire 100 passing through the balloon catheter 200.

[0040] In this embodiment, the guide assembly 20 can be disposed beside the positioning assembly 10. The function of the guide assembly 20 is to allow the guide wire 100 to move along its own axial direction, so as to guide the guide wire 100 from the tail end of the balloon catheter 200 into the balloon catheter 200 and out of the head end of the balloon catheter 200.

[0041] Specifically, combined Figure 1 and Figure 2 As shown in the figure, the guide assembly 20 may include two guide rollers 21. The two guide rollers 21 are arranged relative to each other so as to form a Figure 2 The guide channel s shown is for the guide wire 100 to pass through, and the outer wall of the guide wire 100 passing through the guide channel s contacts the outer walls of the two guide rollers 21. The tail end of the balloon catheter 200 positioned on the positioning platform 11 of the positioning assembly 10 is aligned with the guide channel s.

[0042] Furthermore, the two guide rollers 21 are configured to rotate in opposite directions to apply a force to the guide wire 100 passing through the guide channel s, forcing the guide wire 100 to move toward the direction where the balloon catheter 200 is located.

[0043] It is understandable that, based on the above arrangement, when medical personnel need to operate the guide wire 100 through the balloon catheter 200, they can first insert the balloon catheter 200 as follows: Figure 5 The guide wire 100 is inserted into the positioning groove 12 of the positioning platform 11 in the manner shown to achieve temporary fixation of the balloon catheter 200. Subsequently, the medical staff passes the end of the guide wire 100 through the guide channel s between the two guide rollers 21. On this basis, the two guide rollers 21 are moved in opposite directions. Since the outer wall of the guide wire 100 contacts the outer walls of the two guide rollers 21, and the guide channel s is aligned with the tail end of the balloon catheter 200, the guide wire 100 can move in the direction of the balloon catheter 200 under the action of the friction force provided by the two guide rollers 21, and enter the balloon catheter 200 from the tail end of the balloon catheter 200. After that, it is only necessary to let the two guide rollers 21 continue to rotate, so that the guide wire 100 entering the balloon catheter 200 can be moved as shown in FIG. Figure 5 The guide wire 100 is passed through the tip of the balloon catheter 200 in the manner shown, thus completing the operation of passing the guide wire 100 through the balloon catheter 200 .

[0044] It can be seen that the interventional treatment docking device disclosed in this embodiment, by providing a positioning component 10 for positioning the balloon catheter 200 and a guide component 20 for guiding the guide wire 100 through the balloon catheter 200, can assist medical personnel in conveniently completing the operation of passing the guide wire 100 through the balloon catheter 200, thereby enabling medical personnel to complete the operation of passing the guide wire 100 through the balloon catheter 200 more time-saving and labor-saving.

[0045] Combine Figure 2As shown, the outer wall of each guide roller 21 can be provided with an arcuate groove 211 adapted to fit the guide wire 100. The arcuate groove 211 on a single guide roller 21 extends along the circumference of the guide roller 21 and then closes. In this case, the outer wall of the guide wire 100 passing through the guide channel s contacts the walls of the arcuate grooves 211 of both guide rollers 21. This helps increase the contact area between the guide wire 100 passing through the guide channel s and the two guide rollers 21, thereby increasing the friction acting on the guide wire 100.

[0046] At the same time, an anti-slip structure may be provided on the guide roller 21 to contact the guide wire 100 passing through the guide channel s, thereby further increasing the frictional force acting on the guide wire 100. The anti-slip structure may be an anti-slip pad, anti-slip protrusion, or anti-slip groove provided on the outer wall of the guide roller 21. Furthermore, if the outer wall of the guide roller 21 is provided with an arcuate groove 211, the anti-slip structure may be provided on the wall of the arcuate groove 211 that is intended to contact the guide wire 100.

[0047] In order to enable the two guide rollers 21 to rotate in opposite directions, Figure 2 As shown, the guide assembly 20 further includes two drive motors 22. The two drive motors 22 are respectively connected to the two guide rollers 21 so as to drive the two guide rollers 21 to rotate. Each drive motor 22 can be located below the corresponding guide roller 21.

[0048] At the same time, the guide assembly 20 may also include protective shells 23 corresponding to the two drive motors 22. The two drive motors 22 are respectively installed in the two protective shells 23. In this way, the protective shells 23 can provide protection for the drive motors 22, which is beneficial to improving the service life of the drive motors 22 and helping to optimize the structural design of the guide assembly 20. The output shaft of the drive motor 22 located in the protective shell 23 can pass through the top of the corresponding protective shell 23 and be connected to the corresponding guide roller 21, and the output shaft of the drive motor 22 and the protective shell 23 are rotationally matched.

[0049] Combine Figure 1 As shown, the guide assembly 20 may also include a control box 24 and a control switch 25. The control box 24 houses a controller (not shown), and both drive motors 22 and the control switch 25 are communicatively connected to the controller. This facilitates medical personnel operating the control switch 25 to control the operation of the two drive motors 22.

[0050] Considering that the medical staff needs to remove the balloon catheter 200 together with the guide wire 100 after completing the operation of passing the guide wire 100 through the balloon catheter 200, however, since the guide wire 100 is clamped between the two guide rollers 21 when the operation of passing the guide wire 100 through the balloon catheter 200 is being performed, it is difficult to directly remove the guide wire 100 from between the two guide rollers 21.

[0051] To this end, combined Figure 1 As shown in the content, the docking device disclosed in this embodiment may also include a drive assembly 30, which is configured to drive the two guide rollers 21 to move closer to or away from each other. It can be understood that through the setting of the drive assembly 30, after completing the operation of passing the guide wire 100 through the balloon catheter 200, it is only necessary to use the drive assembly 30 to drive the two guide rollers 21 away from each other to increase the distance between the two guide rollers 21, and the guide wire 100 can be easily removed from between the two guide rollers 21; conversely, it is only necessary to use the drive assembly 30 to drive the two guide rollers 21 closer to each other until the guide channel s formed between the two guide rollers 21 is adapted to the guide wire 100, and the docking device can be used again to complete the operation of passing the guide wire 100 through the balloon catheter 200.

[0052] In which case, when each guide roller 21 is transmission-connected to a corresponding drive motor 22 , and the drive motor 22 is installed in a corresponding protective shell 23 , the drive assembly 30 may be constructed in, but is not limited to, the following manner.

[0053] Combine Figures 2 to 4 As shown in the figure, the driving assembly 30 may include a rotatable driving shaft 31 and two moving parts 32 corresponding to the protective shell 23. The driving shaft 31 extends along the arrangement direction of the two guide rollers 21, and the outer wall of the driving shaft 31 is provided with a Figure 4 The first external thread section and the second external thread section are shown with opposite thread directions. The drive shaft 31 can be arranged below the two protective shells 23.

[0054] The two moving members 32 are configured to be able to slide along the arrangement direction of the two guide rollers 21. One of the moving members 32 is threadedly connected to the first external thread section on the drive shaft 31 and connected to one of the protective shells 23, and the other moving member 32 is threadedly connected to the second external thread section on the drive shaft 31 and connected to the other protective shell 23.

[0055] In this way, when the drive shaft 31 rotates, based on the principle of thread transmission, the two moving parts 32 will drive the corresponding protective shell 23 to move along the axial direction of the drive shaft 31, and then drive the corresponding drive motor 22 and the guide roller 21 to move synchronously through the protective shell 23. Since the thread directions of the first thread segment and the second thread segment are opposite, when the drive shaft 31 rotates, the two moving parts 32 will move in opposite directions, thereby achieving the purpose of making the two guide rollers 21 approach or move away from each other through the rotation of the drive shaft 31.

[0056] In order to enable the two moving members 32 to slide along the arrangement direction of the two guide rollers 21, as shown in FIG. Figure 2 or Figure 4 As shown, the drive assembly 30 may further include a guide post 33. The guide post 33 may be disposed below the drive shaft 31 and parallel to the drive shaft 31, and the guide post 33 simultaneously passes through the two moving members 32 and slidably cooperates with the two moving members 32.

[0057] Furthermore, the drive assembly 30 may further include a knob 34. The knob 34 is coaxially arranged at one end of the drive shaft 31 so that medical personnel can operate the knob 34 to rotate the drive shaft 31.

[0058] Combine Figure 2 and Figure 3 As shown in the figure, the drive assembly 30 may further include a mounting shell 35. The drive shaft 31 and components such as the guide column 33 may be arranged in the mounting shell 35, so as to provide protection for the drive shaft 31, the guide column 33 and other components through the mounting shell 35, and optimize the structural design of the drive assembly 30. One end of the drive shaft 31 may extend outside the mounting shell 35 and be connected to the knob 34. A clearance opening 351 adapted to the two moving parts 32 may be provided at the top of the mounting shell 35, so that the two moving parts 32 can pass through the clearance opening 351 and be connected to the corresponding protective shell 23.

[0059] Combine Figure 1 As shown, the docking device disclosed in this embodiment may further include a base 40 that is generally rectangular. The positioning assembly 10, the guide assembly 20, and the drive assembly 30 are all integrated on the base 40. For example, the positioning platform 11 in the positioning assembly 10 can be fixed to the base 40 via support columns 13, the control box 24 in the guide assembly 20 can be arranged in the space below the positioning platform 11, the control switch 25 can be arranged next to the control box 24, and the mounting housing 35 in the drive assembly 30 can be directly arranged on the base 40, thereby achieving reasonable utilization of limited space.

[0060] It is understandable that by integrating the positioning assembly 10, the guide assembly 20 and the drive assembly 30 on the base 40, it is helpful for medical staff to place the entire docking device on a horizontal surface for use. Figure 2 The suction cup 50 shown is used so that when the docking device is placed on a horizontal surface, the suction cup 50 can be used to absorb and fix the entire docking device on the horizontal surface, thereby improving the stability of the docking device when in use.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
