[0001] This invention relates generally to the technical field of medical devices, and more specifically to an endoscope adapter and an endoscope assembly having the same. Background Technology

[0002] Endoscopes are typically mounted on an endoscope adapter during use. However, because existing endoscope adapters lack a braking mechanism, the endoscope can rotate freely when the adapter is in handheld mode, which is inconvenient for medical staff to operate.

[0003] Therefore, there is a need to provide an endoscope adapter and an endoscope assembly having the same to at least partially solve the above problems. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the present invention provides an endoscope adapter for mounting an endoscope, the endoscope adapter comprising:

[0006] Adapter body;

[0007] An endoscope fixing component is located inside the adapter body and is used to fix it to the endoscope.

[0008] An adapter drive component, located within the adapter body, is drively connected to the endoscope fixation component, enabling the endoscope fixation component to rotate relative to the adapter body around its central axis, thereby rotating the endoscope. The adapter drive component is provided with a stop portion; and

[0009] A braking device connected to the adapter body, the braking device having a brake block corresponding to the stop portion, the brake block being movable between a position engaged with and disengaged from the stop portion.

[0010] Optionally, the stop portion is configured as a recessed structure that extends from the upper surface and / or circumferential surface of the adapter drive member into the body of the adapter drive member.

[0011] Optionally, the stop is provided circumferentially along the adapter transmission member.

[0012] Optionally, the stop includes:

[0013] The bottom wall parallel to the radial direction of the adapter transmission member; and

[0014] Two sidewalls connected to the bottom wall, wherein the sidewalls are perpendicular to the bottom wall, or the angle between the sidewalls and the bottom wall is greater than 90 degrees.

[0015] Optionally, the stop portion is configured as an arcuate surface that is recessed downward from the upper surface of the adapter transmission member.

[0016] Optionally, the braking device further includes a connecting pin and an elastic element. The connecting pin is movably connected to the adapter body along the axial direction of the adapter transmission member. The brake block is connected to the connecting pin. The elastic element is installed inside the adapter body and connected to the connecting pin. The elastic element is used to drive the connecting pin to move along the axial direction of the adapter transmission member, so that the brake block moves to a position where it engages with the stop portion.

[0017] Optionally, the bottom of the adapter body is provided with a connecting pin hole, the lower end of the connecting pin that engages with the stop portion extends through the connecting pin hole and protrudes from the lower surface of the adapter body, and the connecting pin that is disengaged from the stop portion does not protrude from the lower surface.

[0018] Optionally, the endoscope adapter further includes a drive wheel coaxially disposed with the adapter transmission member, and the endoscope fixing member includes a first transmission wheel meshing with the drive wheel.

[0019] Optionally, the endoscope fixing component further includes a second transmission wheel coaxially arranged with the first transmission wheel, and the endoscope adapter further includes a driven wheel meshing with the second transmission wheel, the driven wheel being used to connect an angle detection device.

[0020] The present invention also provides an endoscope assembly comprising an endoscope and the aforementioned endoscope adapter, wherein the endoscope is detachably connected to the endoscope adapter.

[0021] According to the endoscope adapter of the present invention, an adapter body is provided for mounting an endoscope, and an endoscope fixing member and an adapter transmission member are rotatably connected within the adapter body. The endoscope fixing member is fixedly connected to the endoscope and their axes coincide, and the endoscope fixing member is drivenly connected to the adapter transmission member. Thus, the angle position of the endoscope can be adjusted by rotating the adapter transmission member. Furthermore, a stop portion is provided on the adapter transmission member, and a braking device is provided on the adapter body. Specifically, the braking device has a brake block arranged corresponding to the stop portion, and the brake block can move between a position engaged with the stop portion and a position disengaged from the stop portion. When the brake block is engaged with the stop portion, the brake block can restrict the rotation of the adapter transmission member, thereby achieving the purpose of restricting the rotation of the endoscope. When the brake block is disengaged from the stop portion, the brake block avoids the rotation of the adapter transmission member, allowing the endoscope to be rotated. By adopting the above scheme, the state of the braking device can be adjusted as needed, thereby achieving different purposes of allowing endoscope rotation and restricting endoscope rotation. Especially when using the handheld endoscope adapter, adjusting the endoscope to a state of restricted rotation makes it easier for medical staff to operate the endoscope and helps improve operational accuracy.

[0049] 30: Sterile adapter Detailed Implementation

[0050] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the invention.

[0051] To fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0052] This invention provides an endoscope assembly. For example... Figures 1 to 5 ,as well as Figures 8 to 10 As shown, the endoscope assembly includes an endoscope 10 and an endoscope adapter 100, which are detachably connected to facilitate the replacement of the endoscope 10. Typically, during use, the endoscope assembly is also detachably connected to an instrument manipulator 20 via a sterile adapter 30, thereby providing power from the instrument manipulator 20 to drive the endoscope adapter 100 to rotate the endoscope 10. The sterile adapter 30 serves to create a sterile isolation between the instrument manipulator 20 and the endoscope adapter 100.

[0053] The present invention provides an endoscope adapter 100 that, after the endoscope assembly is separated from the sterile adapter 30 and the instrument manipulator 20, and when a medical staff member holds the endoscope adapter 100 to use the endoscope 10, prevents the endoscope 10 from rotating freely relative to the endoscope adapter 100, thereby facilitating the operation of the medical staff member.

[0054] The endoscope adapter 100 according to this embodiment includes an adapter body 110, an endoscope fixing member 160, an adapter transmission member 140, and a braking device 150. The adapter body 110 has a rotatable endoscope mounting base 130, which has a mounting hole for inserting an endoscope 10. After the endoscope 10 is installed on the endoscope mounting base 130, the endoscope 10 and the endoscope mounting base 130 cannot rotate relative to each other.

[0055] An endoscope holder 160 is rotatably disposed within the adapter body 110. The endoscope holder 160 is fixedly connected to the endoscope mounting base 130, and the axis of rotation of the endoscope holder 160 coincides with the axis of the endoscope mounting base 130. An adapter transmission member 140 is rotatably connected to the adapter body 110 and is drively connected to the endoscope holder 160. A stop portion 1411 is provided on the adapter transmission member 140. A braking device 150 is connected to the adapter body 110. The braking device 150 has a brake block 151 arranged corresponding to the stop portion 1411. The brake block 151 is movable between engaging and disengaging from the stop portion 1411.

[0056] According to the endoscope adapter 100 of the present invention, an endoscope 10 is mounted on an adapter body 110. An endoscope fixing member 160 and an adapter transmission member 140 are rotatably mounted within the adapter body 110. The endoscope fixing member 160 is fixedly connected to the endoscope 10 and their axes coincide, and the endoscope fixing member 160 is drively connected to the adapter transmission member 140. Thus, the angular position of the endoscope 10 can be adjusted by rotating the adapter transmission member 140. Furthermore, a stop portion 1411 is provided on the adapter transmission member 140, and a braking device 150 is provided in the adapter body 110. Specifically, the braking device 150 has a brake block 151 arranged corresponding to the stop portion 1411, and the brake block 151 can move between a position engaged with the stop portion 1411 and a position disengaged from the stop portion 1411. When the brake block 151 engages with the stop 1411, the brake block 151 restricts the rotation of the adapter transmission member 140, thereby limiting the rotation of the endoscope 10. When the brake block 151 disengages from the stop 1411, the brake block 151 avoids the rotation of the adapter transmission member 140, allowing the endoscope 10 to rotate.

[0057] By adopting the above scheme, the state of the braking device 150 can be adjusted as needed, thereby achieving different purposes of allowing the endoscope 10 to rotate and restricting the rotation of the endoscope 10. For example, when the endoscope 10 is not installed on the instrument driver, it ensures that the initial position of the endoscope 10 will not change arbitrarily, which helps to calibrate the endoscope 10 after it is installed on the instrument driver, or when the endoscope 10 is removed from the instrument driver, it ensures that the endoscope 10 will not rotate arbitrarily, thus avoiding accidents.

[0058] The endoscope 10 described above includes an endoscope body 11 and an endoscope tube 12. To facilitate a detailed description of the endoscope adapter 100 of the present invention, the following description will be made with reference to the orientation of the endoscope body 11 with its axis parallel to the vertical direction and the endoscope tube 12 located at the lower part of the endoscope body 11. (See attached document.) Figures 1 to 10 .

[0059] Furthermore, the stop portion 1411 is constructed as a recessed structure. This recessed structure can be formed by recessing from the upper surface of the adapter drive member 140 into its body, or from the circumferential surface of the adapter drive member 140 into its body, or from both the upper and circumferential surfaces of the adapter drive member 140 into its body. The purpose is simply to prevent rotation of the adapter drive member 140 when engaged with the brake block 151, and to allow rotation of the adapter drive member 140 when disengaged from the brake block 151.

[0060] Specifically, see Figure 2 , Figure 6 ,as well as Figures 7 to 9 The stop portion 1411 is arranged circumferentially along the adapter transmission member 140, and can be arranged at intervals or continuously. Its purpose is to facilitate locking the angular position of the endoscope 10 by the braking device 150 when the endoscope 10 is rotated to the corresponding angular position. Therefore, to achieve this purpose, it is preferable that the stop portion 1411 is arranged at equal intervals along the circumference of the adapter transmission member 140 to accurately position the angular position of the endoscope 10.

[0061] In addition, see Figures 2 to 9 The braking device 150 also includes a connecting pin 153 and an elastic element 152. The connecting pin 153 is movably connected to the adapter body 110 along the axial direction of the adapter transmission member 140, wherein the axial direction is arranged vertically. The brake block 151 is connected to the connecting pin 153. The elastic element 152 is installed inside the adapter body 110 and connected to the connecting pin 153. The elastic element 152 is used to drive the connecting pin 153 to move downward along the axial direction of the adapter transmission member 140, so that the brake block 151 approaches and engages with the stop portion 1411 (e.g., ...). Figure 3 As shown), if an external force is applied to the lower end of the connecting pin 153 to move it upward until the brake block 151 disengages from the stop part 1411, the rotation restriction of the brake device 150 on the adapter transmission member 140 can be released (e.g., Figure 4 (As shown).

[0062] See Figures 1 to 9 The aforementioned adapter body 110 includes an adapter housing 111 located at the top and an adapter base 112 detachably mounted at the bottom of the adapter housing 111. The adapter housing 111 has a split structure (e.g., Figure 8(As shown). The top wall 113 of the adapter housing 111 has a housing opening 114 for mounting the endoscope mounting base 130. The adapter base 112 has a base opening 116 for the endoscope tube 12 to pass through. The endoscope tube 12 passes through the housing opening 114 and the base opening 116 from top to bottom and extends downward below the adapter base 112.

[0063] The adapter base 112 has a downwardly recessed base recess 115. A mounting member 117 is bolted into the base recess 115. The mounting member 117 is a mounting plate or mounting bracket. The mounting member 117 has a through hole for the endoscope tube 12 to pass through. The endoscope 10 is inserted into and fixed to the endoscope mounting base 130. The lower periphery of the endoscope mounting base 130 is rotatably connected to the mounting member 117 or the adapter base 112 via bearings. The bottom of the endoscope mounting base 130 is bolted to a second drive wheel 162, which is fixedly connected to a first drive wheel 161. The endoscope tube 12 passes sequentially through the shaft holes of the first drive wheel 161 and the second drive wheel 162. The control drive component 141 is coaxially and rotatably assembled with the drive wheel 120 at the lower part of the mounting component 117. The driven drive component 142 and the driven wheel 170 are coaxially and rotatably assembled with the lower part of the mounting component 117. The bottom of the base recess 115 has a control drive component mounting hole for adapting to the control drive component 141 and a driven drive component mounting hole for adapting to the driven drive component 142. A connecting pin hole 118 is provided on the adapter base 112.

[0064] Normally, when the endoscope adapter 100 is connected to the instrument manipulator 20, the adapter drive 140 is allowed to rotate by the instrument manipulator 20, and when the endoscope adapter 100 is disengaged from the instrument manipulator 20 and switched to handheld use, the rotation of the adapter drive 140 is restricted. For this, see [reference needed]. Figures 2 to 5 ,as well as Figure 9 According to the endoscope adapter 100 of the present invention, the bottom of the adapter body 110 is provided with a connecting pin 153 hole 118. When the brake block 151 is engaged with the stop part 1411, the lower end of the connecting pin 153 extends through the connecting pin 153 hole 118 and protrudes from the lower surface of the adapter body 110. When the brake block 151 is disengaged from the stop part 1411, the connecting pin 153 does not protrude from the lower surface.

[0065] In practical implementation, after the endoscope adapter 100 is assembled and connected to the instrument manipulator 20 via the sterile adapter 30, refer to... Figure 10The lower end of the connecting pin 153 can be retracted into the hole 118 of the connecting pin 153 by abutting against the corresponding part of the upper surface of the sterile adapter 30, thereby disengaging the brake block 151 from the stop part 1411, thereby releasing the rotation restriction on the adapter transmission member 140, and then the endoscope 10 can be rotated by the instrument manipulator 20 to adjust the angle position of the endoscope 10.

[0066] As a structure of the stop part 1411 provided by the present invention, see [reference]. Figure 6 The stop portion 1411 includes a bottom wall parallel to the radial direction of the adapter transmission member 140, and two side walls 1412 connected to the bottom wall, wherein the side walls 1412 are perpendicular to the bottom wall, or the angle between the side walls 1412 and the bottom wall is greater than 90 degrees. The structure of this stop portion 1411 is close to a U-shaped groove structure, the length direction of the U-shaped groove is consistent with the radial direction of the adapter transmission member 140, and the U-shaped groove extends along its length direction to the circumferential outer surface of the adapter transmission member 140.

[0067] When the angle between the side wall 1412 and the bottom wall is 90 degrees, after the brake block 151 is engaged between the two side walls 1412, the cooperation between the brake block 151 and the side wall 1412 can reliably restrict the rotation of the adapter. To release this restriction, it is usually necessary to use external force to move the brake block 151 out of the stop part 1411. This embodiment is suitable for using the brake device 150 to achieve the purpose of completely stopping the adapter.

[0068] When the angle between the side wall 1412 and the bottom wall is greater than 90 degrees, the side wall 1412 can form a wedge-shaped abutment with the brake block 151. When the adapter drive 140 is driven to rotate, although the brake block 151 will generate some resistance to the adapter drive 140, if the rotational torque of the adapter drive 140 is sufficient, the side wall 1412 can overcome the elastic force of the elastic member 152 by abutting against the brake block 151 until the brake block 151 moves upward to the protruding surface between two adjacent stops, so that the brake block 151 temporarily disengages from the stops, allowing the adapter to rotate at a certain angle. This implementation is suitable for application scenarios that do not require complete stopping, that is, when the adapter drive 140 stops rotating, the adapter drive 140 can be locked in position. When the adapter drive 140 is driven by a drive source or when an external force is applied, the adapter drive 140 can be allowed to rotate, but it will be subject to some resistance during the rotation of the adapter. In other words, the brake block 151 and the stop portion constitute the damping structure of the adapter transmission 140 along the rotation direction.

[0069] As another structure of the stop 1411 provided by the present invention, see [reference]. Figures 7 to 9The stop portion 1411 is constructed as an arc-shaped surface 1413 recessed downward from the upper surface of the adapter drive member 140. When the stop portion 1411 is composed of an arc-shaped surface 1413, its function is similar to that in the embodiment described above, where the angle between the sidewall 1412 and the bottom wall is greater than 90 degrees. The difference lies in the smooth transition of the arc-shaped surface 1413, which allows the resistance experienced by the adapter drive member 140 to change uniformly during rotation, and also reduces mechanical noise during the rotation of the adapter drive member 140. Furthermore, the arc-shaped surface 1413 can be replaced by other forms of wavy, uneven surfaces, as long as it maintains the current angular position of the endoscope 10 when no external force is applied and the adapter drive member 140 is stopped from being driven.

[0070] In the prior art, the rotational movement of the endoscope 10 is achieved through one or more drive sources. When the endoscope 10 is rotated using a single drive source, the torque is insufficient, resulting in a large current, increasing the load on the drive source, and shortening the service life of the instrument manipulator 20.

[0071] To stably drive the rotation of the endoscope 10, which is heavier than the instrument manipulator 20, multiple drive sources are typically used to increase the torque. However, the scheme of using multiple drive sources to achieve the rotational movement of the endoscope 10 usually requires precise control to achieve coordinated rotation and increase torque, which is complex to implement effectively and is prone to risks.

[0072] Therefore, according to the endoscope adapter 100 of the present invention, see... Figures 2 to 9 The endoscope adapter 100 also includes a drive wheel 120, which is rotatably connected to the adapter body 110. The endoscope fixing member 160 includes a first transmission wheel 161. When both the first transmission wheel 161 and the drive wheel 120 are spur gears, the first transmission wheel 161 is connected to the drive wheel 120 via gear meshing. The axis of the first transmission wheel 161 is parallel to the axis of the drive wheel 120, and the transmission ratio between the drive wheel 120 and the first transmission wheel 161 is less than 1, that is, the number of teeth on the drive wheel 120 is less than the number of teeth on the first transmission wheel 161. The adapter transmission member 140 includes a control transmission member 141, which is connected to the lower part of the drive wheel 120 and coaxially arranged with the drive wheel 120. A stop part 1411 is provided on the control transmission member 141. In specific implementations, the control transmission member 141 can be assembled and connected to the power output part of an external drive source to achieve power transmission. By adopting this preferred solution, precise control of the endoscope's 10-degree angle adjustment can be achieved, and the torque can be effectively improved, thereby reducing the load on the drive source and extending the service life of the drive source.

[0073] The structure of the first transmission wheel 161 and the drive wheel 120 is not limited to using spur gears. In addition, the transmission method between the first transmission wheel 161 and the drive wheel 120 is not limited to gear transmission, but can also be other transmission structures, such as chain transmission, belt transmission, etc.

[0074] When applying the aforementioned endoscope adapter 100 to automated or intelligent medical machines, more precise control of the endoscope's rotation angle is required during operation. For this, please refer to... Figures 2 to 5 , Figure 8 ,as well as Figure 9 According to the endoscope adapter 100 of the present invention, the endoscope adapter 100 further includes a driven wheel 170, which is rotatably connected to the adapter body 110. The endoscope fixing member 160 also includes a second transmission wheel 162 coaxially disposed on the upper part of the first transmission wheel 161. The axis of the second transmission wheel 162 is parallel to the axis of the driven wheel 170. When both the second transmission wheel 162 and the driven wheel 170 are spur gears, the second transmission wheel 162 is connected to the driven wheel 170 in a gear meshing manner. The adapter transmission member 140 also includes a driven transmission member 142 coaxially disposed on the lower part of the driven wheel 170. The driven transmission member 142 is used for an external angle detection device to detect the rotation angle or speed of the driven transmission member 142. By calculating and comparing the output speed with the input speed, the rotation angle error of the endoscope can be calibrated by software.

[0075] When the control transmission component 141 receives power input as a power input terminal, the endoscope 10 is driven to rotate. Simultaneously, the driven wheel 170 is driven to rotate via the second transmission wheel 162, which in turn drives the driven transmission component 142, which is coaxial with the driven wheel 170, to rotate. When an angle detection device is connected to the driven transmission component 142, the angle detection device can acquire the rotation angle information of the driven transmission component 142. The angle detection device is typically connected to the control device of the medical device. The control device receives the angle information from the angle detection device and analyzes it to determine the angular position of the endoscope 10. The obtained angular position information of the endoscope 10 can also be used as a basis for the next adjustment of the endoscope 10's angular position. When needed, the driven transmission component 142 can also be connected to a power source as a power input terminal. In this case, the control transmission component 141 acts as a driven component.

[0076] The structure of the second drive wheel 162 and the driven wheel 170 is not limited to spur gears. In addition, the transmission method between the second drive wheel 162 and the driven wheel 170 is not limited to gear transmission, but can also be other transmission structures, such as chain transmission, belt transmission, etc.

[0077] By employing the endoscope adapter 100 of the present invention, when the endoscope adapter 100 is held in hand, the endoscope 10 cannot rotate freely and remains in a relatively fixed position with the endoscope adapter 100. The rotation of the endoscope 10 can be achieved by a single drive source, simplifying control difficulty, reducing the risk of errors, and increasing torque by a gear module with a variable speed ratio, reducing the load on the drive source and extending the life of the power source.
