[0002] An endoscope is a diagnostic instrument consisting of an endoscope body and a camera assembly. It is one of the important surgical instruments in minimally invasive surgery. An endoscope adapter is an imaging conversion component that connects the endoscope body and the camera assembly.

[0003] An endoscope adapter includes a fixed base and a gripper assembly. The fixed base is connected to a camera assembly. The gripper assembly has an open state and a closed state. When the gripper assembly is in the closed state, it can clamp the endoscope body so that the camera assembly can be used in conjunction with the endoscope body.

[0046] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] An endoscope is a diagnostic instrument consisting of an endoscope body and a camera assembly. It is one of the important surgical instruments in minimally invasive surgery. An endoscope adapter is an imaging transition component that connects the endoscope body and the camera assembly. During endoscopy, the surgeon inserts the endoscope body into the patient's abdominal cavity, bringing it to the location of the lesion. The endoscope body then transmits the image of the lesion to the camera assembly, allowing the surgeon to observe the lesion in real time. The endoscope body includes an objective lens, image transmission element, eyepiece, and illumination element.

[0049] An endoscope adapter includes a mounting base and a gripper assembly. The mounting base is connected to a camera assembly. The gripper assembly has a clamping state and a retracted state. When the gripper assembly is in the retracted state, it clamps the endoscope body, allowing the camera assembly to work with the endoscope body and ensuring that the input light from the camera assembly and the output light from the endoscope body are coaxial. When the gripper assembly is in the open state, it releases the endoscope body, allowing the camera assembly to be detached from the endoscope body.

[0050] However, the gripper assembly in the aforementioned endoscope adapter has poor stability, which poses a risk that the endoscope body may fall out of the gripper during use, resulting in low safety of the endoscope adapter.

[0051] This application provides an endoscope adapter and an endoscope, which can solve the problems existing in the above-mentioned related technologies.

[0052] Figure 1 This is an exploded structural diagram of an endoscope adapter 10 provided in an embodiment of this application. Figure 2 yes Figure 1The schematic diagram of the gripper assembly 12 and locking assembly 13 in the endoscope adapter 10 shown is provided below. Figure 1 and Figure 2 The endoscope adapter 10 may include a fixed base 11, a gripper assembly 12, and a locking assembly 13.

[0053] The fixed base 11 may have a first through hole C1, which can be used to assemble a preset component, which may include a camera assembly.

[0054] The gripper assembly 12 can be located on the side of the fixed base 11 away from the camera assembly. The gripper assembly 12 can include multiple grippers 121, which are arranged circumferentially along the first through hole C1. The gripper assembly 12 can be in an open state or a closed state. The multiple grippers 121 can all be strip-shaped and can be evenly arranged circumferentially along the first through hole C1. When the gripper assembly 12 moves from the open state to the closed state, one end of the gripper 121 can move towards the axis L1 of the first through hole C1, so that the multiple grippers 121 can contact and clamp the endoscope body, thereby holding the endoscope body in the endoscope adapter 10.

[0055] like Figure 2 As shown, the locking assembly 13 may include a locking ring 131 and a limiting protrusion 132. The locking ring 131 can be sleeved on the fixed base 11. The limiting protrusion 132 is located inside the locking ring 131 and is connected to the locking ring 131. The gripper assembly 12 may be located inside the locking ring 131.

[0056] Figure 3 This is a schematic diagram illustrating the structure of a limiting protrusion 132 located at the first position m1, as shown in an embodiment of this application. Figure 4 This is a schematic diagram illustrating the structure of a limiting protrusion 132 located at the second position m2, as shown in an embodiment of this application. Please refer to it. Figure 3 and Figure 4 The limiting protrusion 132 can mate with the locking ring 131 to allow the limiting protrusion 132 to move between a first position m1 and a second position m2. For example... Figure 3 As shown, when the gripper assembly 12 is in the tightened state and the limiting protrusion 132 is in the first position m1, the limiting protrusion 132 can abut against the side of at least one gripper 121 near the locking ring 131. In this way, the limiting protrusion 132 can apply a force to the gripper 121 toward the axis L1 of the first through hole C1, thereby enabling the gripper assembly 12 to remain in the locked state. That is, the locking assembly 13 can lock the gripper assembly 12 in the tightened state, which can improve the stability of the gripper assembly 12 when it is in the tightened state, thereby reducing the risk of the endoscope body falling out of the gripper assembly 12.

[0057] like Figure 4As shown, when the gripper assembly 12 is in the open state and the limiting protrusion 132 is in the second position m2, the limiting protrusion 132 separates from the gripper 121, so that the endoscope body and the endoscope adapter 10 can be disassembled and separated, and the limiting protrusion 132 can avoid affecting the gripper assembly 12 in the open state.

[0058] In summary, this application provides an endoscope adapter, including a fixed base, a gripper assembly, and a locking assembly. The gripper assembly has an open state or a closed state. The limiting protrusion in the locking assembly can move between a first position and a second position. When the gripper assembly is in the closed state and the limiting protrusion is in the first position, the limiting protrusion can abut against the side of at least one gripper near the locking ring. Thus, the locking assembly can lock the gripper assembly in the closed state, improving the stability of the gripper assembly in the closed state. This reduces the risk of the endoscope body dislodging from the gripper assembly during endoscope use, solving the problem of low safety in related technologies and achieving the effect of improving the safety of the endoscope adapter.

[0059] Optionally, in this embodiment, the endoscope adapter 10 serves as a device for connecting the endoscope body and the camera assembly. The gripper assembly 12 may include three grippers 121, i.e., the endoscope adapter 10 in this embodiment is a three-jaw gripping endoscope adapter 10, which makes the endoscope adapter 10 easy to operate and reliable in gripping. The number of limiting protrusions 132 can also be the same as the number of grippers 121, which can be three, to improve the stability of the locking assembly 13. Alternatively, the number of limiting protrusions 132 can be two, four, or more. This embodiment does not limit the number of these protrusions.

[0060] Figure 5 This is a schematic diagram of the structure of a locking assembly 13 and a fixing base 11 provided in an embodiment of this application. Please refer to... Figure 5 , Figure 5 A schematic diagram showing the locking assembly 13 and the fixed base 11 separately, and a schematic diagram showing the locking assembly 13 and the fixed base 11 connected together, are provided. In some alternative embodiments, the fixed base 11 may include an annular base body 111 and a first connecting portion 112. The base body 111 has an annular groove 1111 recessed toward the axis L1 of the first through hole C1. The annular groove 1111 includes a first groove wall k1 and a second groove wall k2, with the first groove wall k1 located on the side of the second groove wall k2 closer to the gripper assembly 12. The first connecting portion 112 is located inside the annular base body 111, and the first through hole C1 may be located on the first connecting portion 112. The first connecting portion 112 may be threadedly connected to the camera assembly.

[0061] Optionally, such as Figure 5As shown, the limiting protrusion 132 can be fixedly connected to the locking ring 131. The locking ring 131 is rotatably connected to the fixed base 11, and the locking ring 131 can rotate about the axis L1 of the first through hole C1. The second groove wall k2 of the fixed base 11 has a limiting step k21. The locking ring 131 can be sleeved on the outside of the limiting step k21, and there is a rotation gap between the locking ring 131 and the limiting step k21. When the locking ring 131 is rotated, the locking ring 131 can rotate around the limiting step k21, which can prevent the rotation trajectory of the locking ring 131 from deviating.

[0062] When the locking ring 131 rotates around the axis L1 of the first through hole C1 in the first direction f1, the locking ring 131 can drive the limiting protrusion 132 to move from the first position to the second position to lock the gripper assembly 12.

[0063] When the locking ring 131 rotates around the axis L1 of the first through hole C1 in the second direction f2, the locking ring 131 can drive the limiting protrusion 132 to move from the second position to the first position, so as to release the locking assembly 13 from locking the gripper assembly 12, wherein the first direction f1 and the second direction f2 are opposite.

[0064] Figure 6 This is a schematic diagram of another endoscope adapter 10 provided in this application embodiment. Please refer to it. Figure 6 Optionally, the endoscope adapter 10 may further include a first elastic element 14, which may be located between the locking assembly 13 and the fixed base 11. The first elastic element 14 may be connected to the locking ring 131 and the fixed base 11 respectively. The first elastic element 14 is in a stretched state to apply a contraction force along the first direction f1 to the locking ring 131, thereby keeping the locking assembly 13 in a locked state, that is, the limiting protrusion 132 in the locking assembly 13 is held in a first position abutting against the gripper 121. If an external force with a contraction force greater than that of the first elastic element 14 rotates the locking ring 131 in the second direction f2, the locking ring 131 can drive the limiting protrusion 132 to move from the first position to the second position. At this time, the gripper assembly 12 can move from a tightened state to an open state to facilitate the installation or removal of the endoscope body. When the external force is removed, the locking ring 131 rotates in the first direction f1 under the contraction force of the first elastic member 14, and drives the limiting protrusion 132 to the first position. At this time, the gripper assembly 12 is in a tightened state, so as to lock the gripper assembly 12.

[0065] In this embodiment, the limiting protrusion 132 can be made to abut against at least one claw in the claw assembly by the contraction force of the first elastic member 14, thereby locking the claw assembly in a tightened state. This can improve the stability of the locking assembly 13 in locking the claw assembly and prevent the limiting protrusion 132 from separating from the claw after the locking ring 131 is touched by the outside when the claw assembly is in the tightened state.

[0066] Figure 7 yes Figure 6 The schematic diagram shown below illustrates the structure of a locking assembly 13, a first elastic element 14, and a fixing base 11 in the endoscope adapter 10. Please refer to the diagram. Figure 7 Optionally, the first elastic element 14 may include a first spring 141, the length direction of which is parallel to the circumferential direction of the locking ring 131. This allows the contraction force exerted by the first spring 141 on the locking ring 131 to be in the same direction as the locking ring 131, thereby improving the utilization efficiency of the contraction force on the first spring 141. The elastic force value of the first spring 141 can be in the range of 8N to 10N, and the first spring 141 can be a compression spring or a tension spring.

[0067] For example, such as Figure 7 As shown, the fixed base 11 also includes a second connecting portion 113, which is fixedly connected to the base body 111. Both the first spring 141 and the first connecting portion 112 are located in the annular groove 1111. The second connecting portion 113 can be a first pin, and the first groove wall k1 of the annular groove 1111 can have a first pin hole k11, in which the first pin can be fitted. The locking assembly 13 may also include a third connecting portion 133, which is located inside the locking ring 131 and fixedly connected to it. The third connecting portion 133 can be a columnar structure.

[0068] The two ends of the first spring 141 can be connected to the second connecting part 113 and the third connecting part 133 respectively, so as to limit the relative movement of the locking assembly 13 and the fixed base 11 within a certain elastic range, and keep the limiting protrusion 132 in contact with the claw 121.

[0069] In this embodiment of the application, the first spring 141 is located in the annular groove 1111 of the fixed base 11. The annular groove 1111 can protect the first spring 141 and prevent the first spring 141 from being affected by other structures.

[0070] Optionally, Figure 8 This is a schematic diagram of the structure of a locking ring 131 provided in an embodiment of this application. Please refer to it. Figure 8The outer wall of the locking ring 131 has a plurality of spaced-apart prismatic protrusions 1311. These plurality of prismatic protrusions 1311 can increase the friction on the outer wall of the locking ring 131, making it easier for the user to rotate the locking ring 131 along the first direction f1 or the second direction f2.

[0071] In one exemplary implementation, such as Figure 7 As shown, the outer wall of the locking ring 131 may also have a silkscreened indicator 1314, which may include an unlocking mark and a locking mark, and can be used to indicate whether the locking component 13 is currently in a first position or a second position, that is, to indicate whether the locking component 13 is in a locked state or an unlocked state. The endoscope adapter 10 may also include a first fixing knob, which can be fixedly connected to the outer wall of the locking ring 131 so that the locking ring 131 can be rotated by rotating the first fixing knob.

[0072] Figure 9 This is a schematic diagram of another endoscope adapter 10 provided in this application embodiment. Please refer to it. Figure 9 Optionally, the endoscope adapter 10 also includes a guide ring 15, which can be sleeved on the fixed base 11 and is located on the side of the gripper assembly 12 away from the fixed base 11. The guide ring 15 may have a plurality of first strip-shaped through holes 151, which are distributed circumferentially along the guide ring 15. The first strip-shaped through hole 151 has a first hole end 151a and a second hole end 151b, with the first hole end 151a located on the side of the second hole end 151b closer to the center of the guide ring 15.

[0073] The gripper assembly 12 also includes a plurality of first connecting shafts 122, which are fixedly connected to the first end 121a of the gripper 121, and the first connecting shaft 122 is at least partially located in the first strip-shaped through hole 151. The first connecting shaft 122 is movable between the first hole end 151a and the second hole end 151b of the first strip-shaped through hole 151, and the second end 121b of the gripper 121 is rotatably connected to the fixed base 11.

[0074] The guide ring 15 can rotate around the axis L1 of the first through hole C1 to drive the first connecting shaft 122 to move in the first strip-shaped through hole 151, thereby driving the first end 121a of the gripper 121 to move along the axis L1 close to the first through hole C1 or along the axis L1 away from the first through hole C1, so that the gripper assembly 12 is in an open state or a tight state.

[0075] In this embodiment, the number of first strip-shaped through holes 151 and the number of first connecting shafts 122 can be the same as the number of grippers 121, and the multiple first strip-shaped through holes 151 can be evenly distributed along the circumference of the guide ring 15.

[0076] Specifically, Figure 10 This is a schematic diagram of the gripper assembly 12 in a tightened state according to an embodiment of this application. Figure 11 This is a schematic diagram of a gripper assembly 12 in an open state according to an embodiment of this application. When the first connecting shaft 122 is located at the first hole end 151a of the first strip-shaped through hole 151, the gripper assembly 12 is in a tightened state. When the first connecting shaft 122 is located at the second hole end 151b of the first strip-shaped through hole 151, the gripper assembly 12 is in an open state.

[0077] Figure 12 yes Figure 9 The schematic diagram shown below illustrates the structure of a guide ring 15, a gripper assembly 12, and a fixing base 11 in the endoscope adapter 10. Please refer to... Figure 12 Optionally, the gripper assembly 12 further includes a plurality of second connecting shafts 123. The first groove wall k1 of the annular groove 1111 of the fixed base 11 has a plurality of second through holes k12, which are evenly distributed on the first groove wall k1. The second connecting shafts 123 are fixedly connected to the second end 121b of the gripper 121, and the second connecting shafts 123 are at least partially located in the second through holes k12.

[0078] The guide ring 15 rotates around the axis of the first through hole C1, causing the first connecting shaft 122 to slide in the strip-shaped through hole, and the second connecting shaft 123 to rotate in the second through hole k12, so as to drive the second end 121b of the gripper 121 to move in a direction close to the center of the first through hole C1, or in a direction away from the center of the first through hole C1.

[0079] When the guide ring 15 rotates around the axis L1 of the first through hole C1, it drives the first connecting shaft 122 to move in the first strip-shaped through hole 151, and the second connecting shaft 123 to rotate in the second through hole k12. This causes the first end 121a of the gripper 121 to move along the axis close to the first through hole C1, or along the axis L1 away from the first through hole C1, so that the gripper assembly 12 is in an open or closed state. For example, the gripper 121 can be arc-shaped, and the number of grippers 121 in the gripper assembly 12 is 3, and the number of second through holes k12 is also 3. When the gripper assembly 12 is in the closed state, a three-point clamping state is formed.

[0080] Optionally, the guide ring 15 may include a first ring 152 and an extension 153. A plurality of first strip-shaped through holes 151 may be located on the first ring 152. The extension 153 is connected to the outer edge of the first ring 152 and is located on the side of the first ring 152 near the fixed base 11. The extension 153 can be fitted onto the outer side of the first groove wall k1 of the annular groove 1111 of the fixed base 11, and a rotation gap is left between the extension 153 and the first groove wall k1. When the guide ring 15 is rotated, the guide ring 15 can rotate around the first groove wall k1 of the fixed base 11, which can prevent the rotation trajectory of the guide ring 15 from deviating.

[0081] The gripper assembly 12 can be located inside the extension 153, that is, the gripper assembly 12 can be located in the space enclosed by the guide ring 15 and the first groove wall k1 of the fixed base 11. In this way, the guide ring 15 and the fixed base 11 can protect the first gripper assembly 12, which can prevent the gripper assembly from being loosened by external force and ensure the stability of the structure.

[0082] like Figure 9 As shown, the endoscope adapter 10 also includes a second elastic element 16, which is located between the guide ring 15 and the fixed base 11. The second elastic element 16 is connected to both the guide ring 15 and the fixed base 11. The second elastic element 16 is in a stretched state to apply a force to the guide ring 15 in the same direction as the second direction f2. This causes the guide ring 15 to keep the gripper assembly 12 in a tightened state.

[0083] If an external force greater than the contractile force of the second elastic element 16 rotates the guide ring 15 in the first direction f1, the guide ring 15 can drive the first connecting shaft 122 to move from the first hole end 151a to the second hole end 151b, thereby driving the first end 121a of the gripper 121 in the gripper assembly 12 to move in a direction away from the axis L1 of the first through hole C1. At this time, the gripper assembly 12 can move from the tightened state to the open state to facilitate the installation or removal of the endoscope body. When the external force is removed, the guide ring 15 rotates in the second direction f2 under the contractile force of the second elastic element 16, and drives the first connecting shaft 122 to move from the second hole end 151b to the first hole end 151a, so that the first connecting shaft 122 is located at the first hole end 151a, and the gripper assembly 12 remains in the tightened state, thus clamping the endoscope body.

[0084] For example, the second elastic element 16 can be a second spring, the length direction of which is parallel to the circumferential direction of the guide ring 15. The fixed base 11 also includes a fourth connecting part (not shown in the figure), which is fixedly connected to the base body 111. Both the second spring and the fourth connecting part are located in the annular groove 1111. The fourth connecting part 114 can be a second pin, and the first groove wall k1 of the annular groove 1111 can have a second pin hole, in which the second pin can be fitted. The guide ring 15 also includes a fifth connecting part 154, which is fixedly connected to the side of the extension 153 in the guide ring 15 near the fixed base 11. The two ends of the second spring can be connected to the fourth connecting part and the fifth connecting part 154 respectively to limit the relative movement between the guide ring 15 and the fixed base 11 within a certain elastic range, thus maintaining the tightened state of the gripper assembly 12.

[0085] The number of second pins can be two, and the number of second springs can also be two. In this embodiment, the number of second pins and second springs can also be one, three, or more, and this embodiment does not limit this. The second pins can be integrally formed with the base body 111 of the fixed base 11, which can improve the structural strength of the fixed base 11.

[0086] The size of the annular groove 1111 of the fixed base 11 can be larger than the outer diameter of the first spring 141 and the second spring, so that the first spring 141 and the second spring can deform and extend within the annular groove 1111. The elastic force of the second spring can be in the range of 8N to 10N, and the second spring can be a compression spring or a tension spring.

[0087] Optionally, Figure 13 This is a schematic diagram of the structure of an endoscope adapter 10 provided in an embodiment of this application. Figure 14 yes Figure 13 The diagram shows a cross-sectional view of the endoscope adapter 10 along the A1-A2 position. Figure 13 and Figure 14 To clearly illustrate the positional relationships of the various structures, an endoscope body 20 is also shown, at least a portion of which can contact the gripper assembly 12 of the endoscope adapter 10. A locking ring 131 is fitted onto the outside of the guide ring 15, and the gripper assembly 12 is located inside the guide ring 15.

[0088] As shown in Figure 15 Figure 15 This is a schematic diagram of the structure of a locking assembly 13, a guide ring 15, and a first toggle button 17 shown in an embodiment of this application. The guide ring 15 has a first notch 155, and a limiting protrusion 132 is at least partially located in the first notch 155, so that the limiting protrusion 132 can pass through the first notch 155 and abut against the jaws 121 in the first jaw assembly 12.

[0089] Optionally, such as Figure 15 As shown, the locking ring 131 may have a second notch 1312, and the endoscope adapter 10 also includes a first toggle knob 17, which is fixedly connected to the guide ring 15, and the first toggle knob 17 is at least partially located in the second notch 1312. Figure 12 As shown, the first toggle knob 17 can be located outside the extension 153 of the guide ring 15. The first toggle knob 17 can be bolted to the guide ring 15, and the first toggle knob 17 can drive the guide ring 15 to rotate relative to the fixed base 11. The first toggle knob 17 can include a knob body 171 and a knob baffle 172. The knob baffle 172 can be used to cover the second notch 1312, which can improve the sealing of the endoscope adapter 10.

[0090] Figure 16 This is a schematic diagram of another locking component 13 provided in an embodiment of this application. Figure 17 It is looking towards f3 along the third direction. Figure 16 Please refer to the structural schematic diagram of the locking assembly 13 shown. Figure 16 and Figure 17 The first direction f3 is parallel to the axis of the locking ring 131 in the locking assembly 13. In an optional embodiment, the endoscope adapter 10 may further include a second toggle knob 18. The locking ring 131 is fixedly connected to the fixed base. The locking ring 131 has a second strip-shaped through hole 1313. The extension direction of the length of the second strip-shaped through hole 1313 is parallel to the circumferential direction of the first through hole. The second toggle knob 18 passes through the second strip-shaped through hole 1313 and is fixedly connected to the limiting protrusion 132. The second toggle knob 18 is at least partially located on the outside of the locking ring 131.

[0091] The second toggle knob 18 is movable within the second through-hole 1313, allowing the limiting protrusion 132 to move between a first position and a second position. When the second toggle knob 18 moves the limiting protrusion 132 along a first direction within the second through-hole 1313, the limiting protrusion 132 moves from the first position to the second position. When the second toggle knob 18 moves the limiting protrusion 132 along a second direction within the second through-hole 1313, the limiting protrusion 132 moves from the second position to the first position; the first and second directions are opposite.

[0092] Optionally, such as Figure 9As shown, the endoscope adapter 10 also includes a top cover 19, which is located on the side of the gripper assembly 12 away from the fixed base 11, and is fixedly connected to the fixed base 11. The top cover 19 may have a second through hole C2, the axis L1 of which may coincide with the axis L1 of the first through hole C1. The second through hole C2 can be used to allow the endoscope lens to pass through the top cover 19 and engage with the gripper assembly.

[0093] The upper cover 19 may include an upper cover body 191, a block protrusion 192, and a second fixing knob 193. Both the block protrusion 192 and the second fixing knob 193 may be located on the outer side of the upper cover body 191 and fixedly connected to it. The upper cover body 191 may be sleeved on the outer side of the guide ring 15. The block protrusion 192 may be integrally formed with the upper cover body 191, and the second fixing knob 193 may be bolted to the upper cover body 191. The second fixing knob 193 has a preset distance between itself and the first toggle knob 17 in the circumferential direction of the first through hole C1. This allows the user to place two fingers on the second fixing knob 193 and the first toggle knob 17 respectively when rotating the guide ring 15. In this case, the second fixing knob 193 remains stationary, while the first toggle knob 17 moves toward the position of the second fixing knob 193. This enables the first toggle knob 17 to rotate the guide ring 15, reducing the operational difficulty during the rotation of the guide ring 15.

[0094] The second groove wall of the annular groove of the fixed base 11 may have multiple third through holes k22. The endoscope adapter 10 may also include multiple fixing bolts. The block protrusion 192 of the upper cover 19 may be connected to the third through hole k22 of the fixed base 11 through the fixing bolts to fix the upper cover 19 and the fixed base 11. In this way, the gripper assembly 12, the guide ring 15 and the locking assembly 13 may all be located between the upper cover 19 and the fixed base 11, and the gripper assembly 12, the guide ring 15, the locking assembly 13 and the fixed base 11 of the upper cover 19 have gaps in the direction parallel to the axis L1 of the first through hole C1 so that the gripper assembly 12, the guide ring 15 and the locking assembly 13 can move.

[0095] In summary, this application provides an endoscope adapter, including a fixed base, a gripper assembly, and a locking assembly. The gripper assembly has an open state or a closed state. The limiting protrusion in the locking assembly can move between a first position and a second position. When the gripper assembly is in the closed state and the limiting protrusion is in the first position, the limiting protrusion can abut against the side of at least one gripper near the locking ring. Thus, the locking assembly can lock the gripper assembly in the closed state, improving the stability of the gripper assembly in the closed state. This reduces the risk of the endoscope body dislodging from the gripper assembly during endoscope use, solving the problem of low safety in related technologies and achieving the effect of improving the safety of the endoscope adapter.
