[0042] like Figure 2 and Fig.10 As shown, the embodiment of the utility model discloses a docking device for docking an instrument docking port 320 of an instrument 300 with a guide tube 800 of a flexible endoscope. The docking device includes a fixing seat 200 , an adapter 500 and an instrument docking member 100 .

[0043] The instrument 300 is detachably connected to the fixing seat 200. The adapter 500 is slidably matched with the fixing seat 200 in a preset direction. The instrument docking member 100 includes a guide tube installation cavity 110 for accommodating the guide tube 800 passing therethrough and an instrument docking groove 120 connected to the guide tube installation cavity 110. Figure 7 When the instrument docking member 100 moves relative to the instrument 300 in a preset direction and a preset distance, the instrument docking groove 120 docks with the instrument docking port 320 of the instrument 300 in place.

[0044] When in use, the instrument docking member 100 is connected to the adapter 500, and then the instrument 300 is installed on the fixing seat 200, and the adapter 500 is moved so that the adapter 500 slides along a preset direction and a preset distance, so that the instrument docking groove 120 and the instrument docking interface 320 of the instrument 300 are docked in place, and the guide tube 800 of the flexible endoscope is installed in the guide tube installation cavity 110, so that the instrument docking interface 320 and the guide tube 800 of the flexible endoscope can be docked, and subsequent related surgical operations can be performed after the docking is completed. It should be noted that the instrument docking member 100 is a disposable consumable, which can avoid contamination of the instrument 300 and reduce the risk of cross infection.

[0045] It should be noted that the instrument 300 includes an instrument docking port 320, which is used to dock with the guide tube 800 of the flexible endoscope. The instrument 300 has a height direction, a length direction and a width direction, and the docking device has a height direction, a length direction and a width direction. When the instrument 300 is installed on the fixing seat 200, the height direction, the length direction and the width direction of the instrument 300 correspond to the height direction, the length direction and the width direction of the docking device.

[0046] The preset direction described above can be understood as any direction. Specifically, the preset direction is the height direction, length direction and width direction of the docking device. The preset direction in the figure is the height direction. Of course, the figure is only exemplary and does not constitute a limiting meaning. The concept of the utility model is to first fix the instrument 300 and the fixing seat 200, or the instrument docking member 100 and the fixing seat 200, and then adjust the instrument 300 or the instrument docking member 100 according to the preset direction to complete the docking of the instrument docking groove 120 with the instrument docking port 320 of the instrument 300.

[0047] The instrument 300 and the fixing seat 200 are detachably connected, for example, they can be connected by a fixing member or by a snap connection, and the specific connection method is not limited. The instrument docking member 100 and the adapter 500 are detachably connected, specifically, they can be connected by a snap connection or by a connecting member, and the specific connection method is not limited.

[0048] In the docking device disclosed in the embodiment of the utility model, the instrument 300 is detachably connected to the fixing seat 200, and the instrument docking member 100 is driven by the adapter 500 to move along the fixing seat 200 in a preset direction, and other directions are limited. After moving a preset distance, the instrument docking groove 120 and the instrument docking interface 320 of the instrument 300 are docked in place, which can realize the rapid docking of the instrument docking interface 320 and the guide tube 800 of the flexible endoscope, which can improve work efficiency, save manpower, and reduce the work intensity of medical staff. At the same time, the docking device disclosed in the embodiment of the utility model has few accessories, simple structure, convenient installation, simple operation, and reliable performance.

[0049] like Figure 1 and Figure 5 As shown, in order to improve the firmness of the docking between the instrument 300 and the instrument docking member 100 and prevent the instrument docking interface 320 from moving, in some specific embodiments, the instrument docking member 100 includes an anti-detachment spring sheet 130, which cooperates with the instrument docking groove 120 to limit the instrument docking interface 320.

[0050] like Figure 5As shown, one end of the anti-dropping spring sheet 130 is connected to the main body of the instrument docking member 100, and the other end of the anti-dropping spring sheet 130 is suspended and is engaged with the instrument docking port 320 when the instrument docking port 320 is located in the instrument docking slot 120, as shown in FIG. Figure 1 As shown. The elastic deformation of the anti-detachment spring sheet 130 can be achieved by axially pressing and contacting the instrument docking interface 320 with the anti-detachment spring sheet 130, and the instrument docking interface 320 is clamped by means of its elastic deformation. This prevents the instrument 300 from accidentally falling off, making the docking of the instrument channel docking interface 320 and the guide tube 800 of the flexible endoscope during the surgical operation safer and more reliable. In addition, the design of the anti-detachment spring sheet 130 preventing the instrument docking interface 320 from detaching by means of deformation can ensure that it is not damaged during the disassembly and assembly process of the instrument 300, and can extend the service life of the instrument docking piece 100.

[0051] In order to fix the guiding tube 800 of the flexible endoscope, in some specific embodiments, such as Figure 7 As shown, the guide tube installation cavity 110 is stepped, or the guide tube installation cavity 110 is arranged in a tapered manner according to the docking direction. For the convenience of explanation, the end of the instrument docking member 100 where the guide tube installation cavity 110 is set is defined as the first end, and the end where the instrument docking groove 120 is set is defined as the second end, then the docking direction refers to the direction extending from the first end to the second end. In order to prevent the angle of the docking channel between the instrument docking interface 320 and the guide tube 800 of the flexible endoscope from being offset due to the deflection of the instrument docking interface 320, the instrument docking groove 320 is set as a rectangular groove. During the operation, the instrument 300 will move, and a circumferential moment will be generated during the movement. The setting of the rectangular groove can prevent the docking angle between the instrument docking interface 320 and the guide tube 800 of the flexible endoscope from being offset due to the action of the circumferential moment, and can improve the reliability and convenience of the operation.

[0052] In some specific embodiments, the adapter 500 is plugged into the instrument docking member 100, one of the adapter 500 and the instrument docking member 100 is provided with a plugging portion 510, and the other is provided with a plugging groove that matches the plugging portion 510, and a limited position protrusion 520 is provided on the plugging portion 510.

When in use, the plug-in portion 510 is inserted into the plug-in slot, and the two are fixed under the limit of the limit protrusion 520, and the plug-in connection method is convenient for assembly and disassembly.

[0053] In order to further ensure the firmness of the fixation between the instrument docking member 100 and the adapter 500, based on the above embodiment, a limiting groove 530 is provided on one of the adapter 500 and the instrument docking member 100, and a pressing buckle 140 matching the limiting groove 530 is provided on the other. Figure 8-Figure 10 As shown, the push buckle 140 is provided on the instrument docking member 100, and the limiting groove 530 is provided on the adapter 500. When in use, the plug-in portion 510 on the adapter 500 is inserted into the plug-in groove on the instrument docking member 100, and then the push buckle 140 is pressed so that the buckle of the push buckle 140 is snapped into the limiting groove 530 to achieve a fixed connection between the two. The design of the push buckle 140 can prevent the deviation of the instrument docking member 100 during use and can limit the position of the instrument docking member 100. In order to facilitate pressing, as shown in FIG. Figure 6 As shown, the shape of the pressing portion of the pressing buckle 140 is similar to the shape of a finger. This design is ergonomic and makes pressing more fitting, labor-saving and convenient to take when achieving a given function. At the same time, the design of the pressing buckle 140 can facilitate users to distinguish the installation positions of the device docking member 100 and the adapter 500 and the device docking port 320, thereby avoiding installation errors by users.

Specifically, the adapter 500 can be detachably connected to the slider 400 by bolts, and can also be connected by bonding. The specific connection method is not limited.

[0055] The device 300 can move when driven by the outside. In order to ensure the movement of the device 300, when the device 300 is installed on the fixed seat 200, the device 300 can slide in a preset direction relative to the fixed seat 200. Specifically, one of the device 300 and the fixed seat 200 is provided with a slide groove 220 extending along the preset direction, and the other is provided with a sliding member matching the slide groove 220. In some specific embodiments, such as Figure 2-Figure 4As shown, the slide groove 220 is arranged on the fixing seat 200, and the slide groove 220 is a U-shaped slide groove, and the sliding member is a boss 310, and is arranged on the instrument 300. When installing, the boss 310 of the instrument 300 is installed in the U-shaped slide groove, and the boss 310 and the U-shaped slide groove are slidably matched. The setting of the U-shaped slide groove can provide a guiding effect for the installation of the instrument 300, can prevent the instrument 300 from deflecting during the movement process, and can also limit the circumferential position of the instrument 300 to prevent the instrument 300 from rotating when moving along the preset direction, and can realize the rapid docking of the instrument docking interface 320 with the guide tube 800 of the flexible endoscope, ensure the reliability and stability of the docking of the instrument docking interface 320 with the guide tube 800 of the flexible endoscope, and make the operation more convenient and reliable.
