[0029] The present invention provides an anti-slip structure 100, which can be used to connect a first component and a second component, so that the first component and the second component can be used separately, and can also make the first component and the second component connected to each other for use, ensuring that the use of the first component and the second component is more flexible and diverse. Among them, the type and structure of the first component and the second component are not specifically limited, and the first component and the second component can be used in combination. Below, for the convenience of explanation, the anti-slip structure 100 is specifically described by taking the example of the first component being set as an oral choledochoscope and the second component being set as a duodenoscope, and other components can refer to the adaptive implementation.

[0030] Specifically, see Figure 1 and Figure 2 In this embodiment, the anti-slip structure 100 includes a first connecting portion 1 suitable for connecting with the first component, and a second connecting portion 2 suitable for connecting with the second component, wherein the first connecting portion 1 is suitable for cooperating with the first matching portion on the first component to form a clamp structure clamped on the outer peripheral side of the first component; the second component is detachably connected to the second connecting portion 2, and when the second component is installed on the second connecting portion 2, the second connecting portion 2 can provide a certain locking force on the second component to limit the second component from escaping from the second connecting portion 2.

[0031] In this embodiment, the first connecting portion 1 is suitable for connecting with the first component (such as an oral choledochoscope), and the second connecting portion 2 is suitable for connecting with the second component (such as a duodenoscope), so that the first component and the second component can be used in conjunction with each other, so that the relative positions between the two components are fixed, which facilitates the coordinated operation of the two components; moreover, the first connecting portion 1 can cooperate with the first matching portion on the first component to form a clamp structure, so as to be clamped on the outer peripheral side of the first component, so that the connection between the first connecting portion 1 and the first component is more stable and reliable; and the second component and the second connecting portion 2 are detachably connected. Then, the anti-slip structure 100 can be connected and fixed to the first component without disassembly, making the second component easy to assemble and disassemble, and the two components can be better used separately and in combination, and the usage is more flexible and diverse; and when the second component is installed on the second connecting part 2, a certain locking force can be provided on the second component through the second connecting part 2, so that the second component can be better maintained in a state fixed on the anti-slip structure 100, so that when in use, the second component is not easy to fall off from the anti-slip structure 100, and is more stable and safer during the treatment process.

[0032] It is understood that since the anti-slip structure 100 can connect and fix two components, when the two components need to be used separately, one of the components can be disassembled to fix the anti-slip component to the other component, avoiding the need to disassemble both components during disassembly, and then assembling them twice when they are used together again. Preferably, the anti-slip structure 100 can be connected and bound to the first component, making the second component easy to assemble and disassemble. To facilitate the disassembly and assembly of the second component, when the second component is fixed to the anti-slip structure 100, a certain locking force can be applied to the second component through the second connecting portion 2, ensuring a more reliable connection when the second component and the first component are used together. When the second component needs to be disassembled, a force greater than the locking force can be applied to the second component, so that the second component can be disengaged from the lock of the second connecting portion 2 for removal. It is understood that when disassembling the second component, it can be driven by a driving component or manually disassembled. Preferably, the second component is manually operated to remove and install the second component, making the structure simple and easy to operate.

[0033] It should be noted that the clamp structure is annular, and the first connecting portion 1 and the first matching portion are respectively arc-shaped, so as to together enclose a full-circle annular clamp structure. Therefore, preferably, at least a portion of the first component is cylindrical, and the clamp structure can be clamped onto the cylindrical section of the first component, thereby being fixed to the first component. For example, when the first component is configured as an oral choledochoscope, the clamp structure can be clamped onto the outside of the main body of the oral choledochoscope.

[0034] Specifically, the first fitting portion and the first connecting portion 1 can form a stop fit along the axial direction of the clamp structure to limit the relative movement of the anti-slip structure 100 and the first component along the axial direction of the clamp structure. The second connecting portion 2 is provided on the outside of the clamp structure, and the second component is suitable for moving along the axial direction of the clamp structure to be installed on or removed from the second connecting portion 2. The second connecting portion 2 can provide an axial force on the second component along the axial direction of the clamp structure to limit the second component from being dislodged from the second connecting portion 2. By limiting the anti-slip structure 100 to the first component along the axial direction of the clamp structure, the second component can be installed or disassembled on the anti-slip structure 100 along the axial direction of the clamp structure, so that the assembly and disassembly of the second component will not affect the relative position between the anti-slip structure 100 and the first component, thereby ensuring that the relative position between the first component and the second component is more accurate.

[0035] Preferably, combined Figure 1 and Figure 2As shown, the second connecting portion 2 includes a limiting groove 21 and a locking portion 22 provided on one side of the limiting groove 21. The limiting groove 21 extends along the axial direction of the clamp structure, and one end of the limiting groove 21 along the axial direction of the clamp structure is open. The locking portion 22 is located on the open side of the limiting groove 21. At least a portion of the second component is slidably provided in the limiting groove 21. The second component is mounted on the anti-slip structure 100 by sliding into the limiting groove 21 and removed from the anti-slip structure 100 by sliding out of the limiting groove 21. Furthermore, the locking portion 22 locks at least a portion of the second component in the limiting groove 21, so that when the second component is mounted on the anti-slip structure 100, the second component is not easily detached from the anti-slip structure 100, ensuring that the second component is more stable and less likely to become loose when the first and second components are used together.

[0036] Further, combined with Figure 2 and Figure 3 As shown, the locking portion 22 includes an elastic hook 221 provided on the open side of the limiting groove 21. The hook portion of the elastic hook 221 is provided close to the limiting groove 21 so as to be suitable for abutting and fixing the second matching portion on the second component within the limiting groove 21. When the second component is disassembled, the deformation of the elastic hook 221 makes disassembly more labor-saving and more convenient. The elastic hook 221 restricts the second matching portion, which, on the one hand, can ensure a reliable connection between the second component and the anti-slip structure 100, and on the other hand, makes the disassembly of the second component more convenient. Preferably, the cross section of the limiting groove 21 is T-shaped, and the second matching portion includes a snap-fitting boss. The cross section of the snap-fitting boss is also T-shaped, so that after the snap-fitting boss is clamped in the limiting groove 21, it is not easy to rotate in the circumferential direction, thereby ensuring a better connection effect.

[0037] For the first connecting portion 1, combined Figure 2 and Figure 3 As shown, the first connecting portion 1 includes a first clamping plate 11, and a mounting portion 12 and a clamping portion 13 provided at both ends of the first clamping plate 11 along the circumference of the clamp structure. The first clamping plate 11 is arranged in an arc shape so as to be disposed together with the first mating portion around the outer circumference of the first component. The mounting portion 12 and the clamping portion 13 are respectively adapted to connect with both ends of the first mating portion. The mounting portion 12 and the clamping portion 13 allow the first clamping plate 11 to be connected and fixed to the first mating portion, providing a relatively secure connection and allowing for disassembly for maintenance.

[0038] Preferably, if Figure 3As shown in , the mounting portion 12 includes a first clamping hole 121 provided on the first clamping plate 11, and the first clamping hole 121 can be used to clamp with the buckle on the first matching portion; the clamping portion 13 includes a clamping protrusion 131 provided on the first clamping plate 11, and the clamping protrusion 131 is used to clamp into the second clamping hole on the first matching portion, and at least partially protrudes from the second clamping hole for easy disassembly. The locking portion 22 is provided on the outer annular surface of the first clamping plate 11 and is located between the first clamping hole 121 and the clamping protrusion 131, making the structure more compact and occupying less space. The limiting groove 21 is provided on the outer annular surface of the first clamping plate 11 and is located at one end of the locking portion 22 along the axial direction of the clamp structure, ensuring that the second component has sufficient space for assembly and disassembly.

[0039] Moreover, a plurality of limiting ribs are protruding from the inner side wall of the limiting groove 21, and each of the limiting ribs is extended along the axial direction of the clamp structure to be suitable for abutting against the outer peripheral side of the second matching part, so that when the second matching part is accommodated in the limiting groove 21, it is not easy to shake and is more stable.

[0040] The present invention also provides an endoscope, which includes an endoscope body and a matching structure provided on the endoscope body, wherein the matching structure is suitable for matching and connecting with the first connecting part 1 and / or the second connecting part 2 of the anti-detachment structure 100, so that the endoscope can not only be used alone, but also can be used in combination with other components.

[0041] In one embodiment, the endoscope body includes a first main body structure, and the mating structure includes a first mating portion provided on the first main body structure. The first mating portion is adapted to be mated and connected with the first connecting portion 1 of the anti-slip structure 100 to form a clamp structure disposed around the outer periphery of the endoscope body. The anti-slip structure 100 is connected and fixed to the outer periphery of the first main body structure, so that it can be connected to other components through the anti-slip structure 100, allowing the endoscope to be better used in conjunction with different other endoscopes or components.

[0042] Specifically, the first matching part includes a second clamping plate, which is arranged in an arc shape and is suitable for being arranged together with the first clamping plate 11 of the first connecting part 1 on the outer peripheral side of the first main structure. The second clamping plate is provided with a buckle at one end along its circumference, and a second clamping hole is provided at the other end along its circumference. The buckle is suitable for being snap-fitted with the first clamping hole 121 on the anti-slip structure 100, and the second clamping hole is suitable for being snap-fitted with the clamping protrusion 131 on the anti-slip structure 100, so that the formed clamp structure can be tightly clamped on the outer peripheral side of the first main structure.

[0043] In another embodiment, the endoscope body includes a second main body structure, and the matching structure includes a second matching portion provided on the second main body structure, and the second matching portion is suitable for being detachably connected to the second connecting portion 2 of the anti-slip structure 100, and the second connecting portion 2 can provide a certain locking force on the second matching portion to connect and fix the second main body structure and the anti-slip structure 100, so that the second main body structure can be connected to the anti-slip structure 100, so that the second main body structure can be better used alone, and can be used in conjunction with other components.

[0044] Preferably, the second mating portion includes a snap-fitting boss protruding from the outside of the second main body structure, the snap-fitting boss is suitable for being accommodated in the limiting groove 21 on the anti-slip structure 100, and the locking portion 22 on the anti-slip structure 100 abuts against one side of the snap-fitting boss, and the locking portion 22 abuts against the snap-fitting boss to limit the snap-fitting boss in the limiting groove 21, thereby connecting and fixing the second main body structure and the anti-slip structure 100.

[0045] In another embodiment, the endoscope body may include a first main body structure and a second main body structure, and the first main body structure and the second main body structure are connected by the anti-detachment structure 100, so that the relative position between the first main body structure and the second main body structure is fixed, so that the first main body structure and the second main body structure can be better used in combination.

[0046] Preferably, the first main structure can be set as an oral choledochoscope, and the second main structure can be set as a duodenoscope. The oral choledochoscope and the duodenoscope are connected and fixed by the anti-detachment structure 100. During relevant gastroenterology surgeries, the operation is more convenient, and the endoscopes are not easy to loosen and fall off, which is more conducive to the operation of the instrument and improves the surgical effect.
