Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a locking device for adjusting an endoscope and a locking device; this application also relates to an endoscope using the above-mentioned locking device. Background Technology

[0002] With the development of modern medical technology, the advancement of medical techniques, and the popularization of advanced medical equipment, endoscopic equipment is being used more and more widely in routine medical surgeries.

[0003] Endoscopic devices, as commonly used medical instruments, mainly consist of a traction wire, a flexible part, a light source, and a lens. In practical applications, the endoscope's tip is inserted into the body through a minimally invasive incision. After adjusting the tip to a suitable position, the endoscope is usually fixed at a certain angle. To facilitate observation of lesions, a locking device is installed on the endoscope. This locking device at the rear of the endoscope allows for movement control of the flexible part, thereby adjusting the observation angle of the tip and directly visualizing lesions. The endoscope locking device, as a crucial component in actual surgical procedures, plays a vital role in achieving observation of lesions.

[0004] In existing endoscope locking devices, a locking handwheel is typically used to adjust the lens. However, this method suffers from problems such as insufficient stability, low precision, and inflexible bending angle when manipulating the lens during operation. Therefore, how to provide a locking device for endoscope adjustment that improves the angular flexibility and stability of the endoscope lens during operation has become a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides a locking device for endoscope adjustment to solve the problems of insufficient operational stability, low precision, and inflexible bending angle of existing endoscope locking structures. The present invention also provides a locking device and an endoscope using the above-described locking device for endoscope adjustment.

[0006] According to an embodiment of this application, a locking device for endoscope adjustment is provided, comprising: a first rotating wheel, a first rotating shaft, and a braking element;

[0007] The first rotating wheel is connected to the first end of the first rotating shaft; a first traction disc is provided on the first rotating shaft; the braking element is used to provide desired damping for the rotation of the first rotating shaft, and the rotation of the first traction disc is used to adjust the first traction wire, thereby adjusting the observation angle of the endoscope in the first dimension.

[0008] In one possible implementation, the system further includes a body and a brake drive, the brake drive including a first brake assembly drive, the brake including a first brake assembly;

[0009] The first traction disc is located at the middle of the first rotating shaft, and the second end of the first rotating shaft is located inside the machine body;

[0010] The first braking assembly has a third rotating shaft disposed within the first rotating shaft. The third rotating shaft rotates independently of the rotation of the first rotating shaft. A brake disc is connected to the second end of the third rotating shaft. The brake disc is disposed in a brake hole on one side of the machine body. A tongue extending spirally along the circumference is disposed on the inner diameter of the brake hole. A wedge-shaped surface is disposed on the end face of the brake disc. The wedge-shaped surface cooperates with the tongue disposed in the brake hole and can enter the gap between the tongue and the inner diameter surface of the brake hole.

[0011] The first brake assembly drive is disposed at the first end of the third rotating shaft. By manipulating the first brake assembly drive, the rotation angle of the brake disc can be adjusted by means of the third rotating shaft. By the wedge-shaped surface on the brake disc being in contact with or not in contact with the tongue, and the degree of contact, different degrees of compression can be applied to the first rotating shaft by the tongue, thereby achieving the desired damping for the rotation of the first rotating shaft.

[0012] In one possible implementation, the wedge-shaped surface has different inner diameter dimensions along the circumferential direction, and the tongue that mates with the wedge-shaped surface is disposed along the inner diameter surface of the brake hole. The tongue has the same or different thicknesses along the circumferential direction, and when the wedge-shaped surface and the tongue are in contact, different degrees of compression in the direction of the first rotation axis can be obtained at different contact positions.

[0013] In one possible implementation, the wedge-shaped surfaces are provided in multiple locations and are arranged around the circumferential surface of the brake disc; the multiple wedge-shaped surfaces are evenly or unevenly arranged on the circumference.

[0014] In one possible implementation, the first braking component drive is a knob positioned on the end face of the first rotating wheel. By manipulating the knob, the third rotating shaft rotates in tandem with the knob, adjusting the rotation angle between the brake disc and the first rotating shaft, thereby adjusting whether the wedge-shaped surface on the brake disc is in contact with or not in contact with the tongue, and the degree of contact.

A second traction disc is provided at the second end of the second rotating shaft. The second rotating shaft has a portion that extends out of the housing of the locking device.

[0017] The second braking component is a tensioning plate with a cantilever beam structure. The tensioning plate is positioned on the outer surface of the housing of the locking device body and is arranged around the portion of the second rotating shaft that extends out of the housing.

[0018] The second braking drive component radially compresses the tensioning plate, causing it to contract radially. This causes the inner diameter surface of the tensioning plate to conform to the outer circumferential surface of the second rotating shaft, thereby applying frictional force to the second rotating shaft. By varying degrees of compression, the tightness of the fit between the inner diameter surface of the tensioning plate and the outer circumferential surface of the second rotating shaft can be adjusted, thus applying different frictional forces to the second rotating shaft. The rotation of the second traction disc adjusts the second traction wire, thereby adjusting the observation angle of the endoscope in a second dimension, which is in a different directional dimension from the first dimension.

[0019] In one possible implementation, the second brake drive includes a cam disposed on the outer surface of the housing of the body, which can apply different degrees of compression to the tension plate by rotating the cam to different angles.

In this embodiment, as a most likely arrangement, the coaxiality is achieved by the second rotating shaft 133 being sleeved on the outer circumferential surface of the first rotating shaft 113, and the second rotating shaft 133 can rotate independently of the rotation of the first rotating shaft 113; the second traction disc 135 is fixedly located at the second end of the second rotating shaft 133. As can be seen from the figure, the second traction disc 135 is located at the first end relative to the first traction disc 115 (…). Figure 3 (Right side) Position. Furthermore, the first rotating wheel 111 is located closer to the first end of the second rotating wheel 131, and the first rotating wheel 111 is provided with a boss extending towards the second end, while the second rotating wheel 131 is provided with a corresponding groove, allowing the boss to embed into the groove, thereby shortening the axial installation dimensions of the first rotating wheel 111 and the second rotating wheel 131. Of course, the coaxial arrangement of the first rotating shaft 113 and the second rotating shaft 133 can also be achieved in other ways, such as arranging them opposite each other from both ends. If this arrangement is adopted, the layout of the entire locking device will be significantly different from this embodiment, but its principle is not fundamentally different.

[0106] After introducing the structure and connection relationship of each shaft and wheel, the structure of each traction disc will be introduced next. In the locking device 10 of this application, the structure of the first traction disc 115 and the second traction disc 135 are similar. For ease of understanding, the structure of the first traction disc 115 will be used as an example for detailed explanation.

[0107] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the first traction disc 115 in the locking device 10. The figure also shows the first rotating shaft 113 connected to the first traction disc 115. The following is in conjunction with... Figure 5 For a detailed description of the specific structure of the first traction disc 115, please also refer to... Figure 1 .

[0108] The first traction disc 115 is located at the middle of the first rotating shaft 113; the first traction disc 115 has a position for fixing the first traction wire 1153. By rotating the first traction disc 115, the extension distance of the first traction wire 1153 can be adjusted, and the first traction wire 1153 can pull the endoscope lens, so that the endoscope is at a suitable angle in the dimension controlled by the first traction wire 1153.

[0109] according to Figure 5As shown, the first traction disc 115 includes: a first traction disc groove 1151; a first traction wire 1153; a first traction hole 1155; and a first traction disc center hole 1157.

[0110] The first traction disc 115 is a hollow disc structure. The first traction disc groove 1151 is located on the outer circumferential surface of the first traction disc 115. The first traction wire 1153 enters the first traction disc 115 through the first traction disc groove 1151. The circumferential surface of the first traction disc 115 is provided with symmetrical bidirectional first traction holes 1155. The symmetrical first traction holes 1155 are used for the intake and release of the first traction wire 1153. The center position of the first traction disc 115 is provided with a first traction disc center hole 1157, which is fitted and fixed with the first rotating shaft 113. Through this structure, the first traction disc 115 is installed at the second end of the first rotating shaft 113.

[0111] One end of the first traction wire 1153 is fixed to the first traction disc 115 and can be inserted into the groove 1151 of the first traction disc. By rotating the first traction disc 115, the extension and retraction of the first traction wire 1153 can be adjusted, thereby adjusting the observation angle of the endoscope in the first dimension. Specifically, the rotation of the first traction disc 115 can control the winding and retraction of the first traction wire 1153 in the first dimension, thereby adjusting its extension distance. As a possible arrangement, in this embodiment, the first traction wire 1153 consists of two traction lines. The observation angle in the first dimension is in the vertical direction. The two traction lines of the first traction wire 1153 each independently control the observation angle of the endoscope in the vertical direction. In this embodiment, the composition and control dimension of the first traction wire 1153 described above are only an illustration, and other possible compositions and control methods for the first traction wire 1153 are not excluded.

[0112] The second traction disc 135 has a structure similar to the first traction disc 115, which will not be described in detail in this embodiment. In this embodiment, the second traction disc 135 rotates following the second rotating shaft 133. Since a second traction wire is fixed on the second traction disc 135, and the composition of the second traction wire is similar to that of the first traction wire 1153 described above, the rotation of the second traction disc 135 can adjust the extension and retraction of the second traction wire, thereby adjusting the observation angle of the endoscope in the second dimension, for example, the observation angle of the endoscope in the left-right direction; specifically, the rotation of the second traction disc 135 can control the winding and retraction of the second traction wire, thereby adjusting its extension distance. The second dimension is in a different directional dimension from the first dimension.

[0113] In this embodiment, the first traction wire 1153 and the second traction wire are both embedded in the endoscope's catheter. The two ends of each traction wire are respectively positioned at the curved end and the traction disc end of the endoscope catheter. One end is connected to the corresponding traction disc, and the other end is fixed in the catheter. Generally, after one end of a traction wire is pulled by the corresponding traction disc, when the traction disc rotates, due to the flexibility of the catheter, the traction wire drives the rotation of the flexible part at the distal end of the catheter, thereby causing the endoscope lens to rotate in a certain dimension (first or second), so that the endoscope lens can deflect at a certain angle and change the observation angle.

[0114] The above content introduced the rotary wheel assembly 100. Next, we will introduce the brake component 300 and the brake drive component 500. Since the two are closely related, there is some overlap in the introduction process.

[0115] The braking component 300 includes: a first braking assembly 310; and a second braking component 330.

[0116] The brake drive 500 includes: a first brake assembly drive 510; and a second brake drive 530.

[0117] In the locking device 10 of this application, the first braking component 310 works in conjunction with the first braking component drive 510, and the second braking component 330 works in conjunction with the second braking component drive 530, thereby realizing the individual braking of the first rotating shaft 113 and the second rotating shaft 133. Since the braking methods of the first rotating shaft 113 and the second rotating shaft 133 are significantly different, they will be described separately in the following sections based on their individual braking methods.

[0118] The first braking assembly 310 and the first braking assembly drive 510 are described below.

[0119] The first braking assembly 310 in the braking component 300 includes: a third rotating shaft 311; a brake disc 313; a wedge-shaped surface 3131; and a rotating shaft through hole 3133.

[0120] The first braking assembly 310 has a third rotating shaft 311 disposed within the first rotating shaft 113 (the third rotating shaft 311 can rotate independently of the rotation of the first rotating shaft 113), and a brake disc 313 connected to the second end of the third rotating shaft 311. The brake disc 313 is fitted into a brake hole 720 on one side of the handle (body) 700. A circumferential wedge-shaped surface 3131 is provided on the end face of the brake disc 313. The wedge-shaped surface 3131 is used to cooperate with the tongue 721 in the brake hole 720.

[0121] Please refer to Figure 6 The indication, Figure 6This is a schematic diagram of the brake disc 313, which also shows the third rotating shaft 311. In this embodiment, as a specific implementation, a rotating shaft through hole 3133 is provided at the center of the end face of the brake disc 313. The rotating shaft through hole 3133 is used to fix the brake disc 313 to the second end of the third rotating shaft 311, and the brake disc 313 can rotate with the rotation of the third rotating shaft 311. The brake disc 313 is disposed in the brake hole 720 of the handle 700 body, and the inner surface of the brake hole 720 of the handle (body) 700 is a rough surface, which can provide a large frictional force for the rotation of the brake disc 313, so that after the brake disc 313 rotates to a certain extent, the rotation of the first rotating shaft 113 cannot be stopped. The brake disc 313 is rotated at this rotation angle; multiple wedge-shaped surfaces 3131 are provided on the end face of the brake disc 313 and are arranged around the circumference of the brake disc 313; the multiple wedge-shaped surfaces 3131 are evenly arranged on the circumference, and the wedge-shaped surfaces 3131 have different radial dimensions along the circumference, so that when the wedge-shaped surfaces 3131 are in contact with the tongue 721, the wedge-shaped surfaces 3131 can enter the gap between the tongue 721 and the inner diameter surface of the brake hole 720; by applying different degrees of compression to the first rotating shaft 113 through the tongue 721, the desired damping for the rotation of the first rotating shaft 113 is achieved.

[0122] In this embodiment, the second end of the third rotating shaft 311 ( Figure 3 The second end of the first rotating shaft 113 is disposed in the gap between the right side and the wedge surface 3131. During the process of the wedge surface 3131 fitting the tongue 721 of the brake hole 720, the wedge surface 3131 can wedge into the gap between the tongue 721 and the inner diameter surface of the brake hole 720. Depending on the wedge depth, different degrees of compression can be applied to the first rotating shaft 113 through the tongue 721, thereby providing the desired damping to the first rotating shaft 113.

[0123] The first braking component drive 510 includes a knob 511.

[0124] refer to Figure 3 As illustrated in the diagram, the first braking assembly drive 510 is essentially a knob 511, which is located at the first end of the third rotating shaft 311. Figure 3(Left side), and positioned on the end face of the first rotating wheel 111. By rotating the knob 311, the third rotating shaft 311 is driven to rotate synchronously. The brake disc 313 at the second end of the third rotating shaft 311 follows the rotation of the third rotating shaft 311, thereby adjusting the rotation angle between the brake disc 313 and the first rotating shaft 113. This allows for adjustment of whether the wedge-shaped surface 3131 on the brake disc 313 is in contact with or not in contact with the tongue 721 in the brake hole 720, as well as the degree of contact. This allows the tongue 721 to apply different sizes of pressure to the first rotating shaft 113, providing the desired damping for the rotation of the first rotating shaft 113.

[0125] Next, we will introduce the second braking component 330 and the second braking component drive component 530.

[0126] The second brake member 330 is disposed on the part of the second rotating shaft 133 that extends out of the housing of the handle 700 of the locking device 10. The second brake member drive member 530 is disposed on at least one side of the second brake member 330 via the positioning shaft 710 on the handle 700. By swinging the second brake member drive member 530, radial compression of the second brake member 330 can be achieved, thereby applying frictional force to the second rotating shaft 133.

[0127] The second braking component 330 includes a tensioning plate 331.

[0128] The second brake drive member 530 includes: a cam 531; and an operating handle 533.

[0129] For easier understanding, please refer to Figure 7 The indication, Figure 7 This is a schematic diagram of the structure of the second braking component 330 and the second braking component drive component 530;

[0130] The second braking component 330 is essentially a tensioning plate 331 with a cantilever beam structure. In this embodiment, the tensioning plate 331 is specifically annular, and a notch is provided on the annular tensioning plate 331. The tensioning plate 331 is positioned on the outer surface of the housing of the handle 700 of the locking device 10, and is arranged around the portion of the second rotating shaft 133 that extends out of the housing. By radially pressing the tensioning plate 331, the tensioning plate 331 is radially contracted, thereby causing the inner diameter surface of the tensioning plate 331 to fit against the outer circumferential surface of the second rotating shaft 133, thus applying frictional force to the second rotating shaft 133. By applying different degrees of pressure, the tightness of the fit between the inner diameter surface of the tensioning plate 331 and the outer circumferential surface of the second rotating shaft 133 can be adjusted, thereby applying different frictional forces to the second rotating shaft 133.

[0131] The second brake drive component 530 includes a cam 531 disposed on the outer surface of the housing of the handle 700, and an operating handle 533 connected to the cam 531. The operating handle 533 has a length significantly larger than the radius of the handle 700. By manipulating the operating handle 533, the cam 531 is rotated to different angles, thereby applying different degrees of compression to the tension plate 331. Through different degrees of compression, the tightness of the fit between the inner diameter surface of the tension plate 331 and the outer peripheral surface of the second rotating shaft 133 can be adjusted, thereby applying different frictional forces to the second rotating shaft 133. A positioning device can also be provided for the operating handle 533 to position it in a desired location, thereby positioning the cam 531 at a desired angle and maintaining the degree of compression applied to the tension plate 331. Specifically, the operating handle 533 can be positioned close to the housing of the handle 700 with a set of gears that cooperate with each other. When the gears are engaged, the movement of the operating handle 533 is limited, thereby positioning the cam 531 in the desired position. When the gears are disengaged, the operating handle 533 can swing freely, and the cam 531 swings with the operating handle 533.

[0132] When the endoscope is in operation, to brake the first rotating shaft 113, the knob 511 is rotated, causing the third rotating shaft 311 to rotate. The rotation of the third rotating shaft 311 then rotates the brake disc 313, thereby adjusting the rotation angle between the brake disc 313 and the first rotating shaft 113. By adjusting the contact between the wedge-shaped surface 3131 on the brake disc 313 and the tongue 721 within the brake hole 720, and the degree of contact, different degrees of pressure can be applied to the first rotating shaft 113 via the tongue 721, thus providing the desired damping for the rotation of the first rotating shaft 113. The rotation of the first traction disc 115 is used to adjust the first traction wire 1153, thereby adjusting the endoscope. In the first dimension of observation; regarding the braking of the second rotating shaft 133, by manipulating the operating handle 533, the cam 530 connected to the operating handle 533 is rotated to different angles and positioned at the required angle. The cam 530 at different angles achieves different degrees of compression on the tension plate 331 of the cantilever beam structure, thereby adjusting the tightness of the fit between the inner diameter surface of the tension plate 331 and the outer peripheral surface of the second rotating shaft 133. The adjustment of the tightness of the fit applies different frictional forces to the second rotating shaft 133. The rotation of the second traction disc 135 adjusts the second traction wire 1353, thereby adjusting the observation angle of the endoscope in the second dimension, which is in a different directional dimension from the first dimension.

[0133] The independent adjustment of the observation angle of the endoscope in the first and second dimensions is achieved by braking the first rotating shaft 133 and the second rotating shaft 133 separately. Generally, the locking device 10 can have an unlocked state and a locked state, and can provide different degrees of damping in the middle position between the two.

[0134] The following details the operation of the locking device 10, focusing on the switching between locking and unlocking.

[0135] When the endoscope locking device 10 needs to be locked in the first dimension, the knob 511 is rotated clockwise (or counterclockwise, depending on the actual application scenario), causing the third rotating shaft 311 to rotate clockwise. The rotation of the third rotating shaft 311 synchronously drives the brake disc 313 to rotate, thereby increasing the rotation angle between the brake disc 313 and the first rotating shaft 113. This causes the wedge-shaped surface 3131 on the brake disc 313 to adhere to the tongue 721 within the brake hole 720. Furthermore, as the rotation angle increases, the degree of adhesion between the wedge-shaped surface 3131 and the tongue 721 deepens. The gap between the tongue 721 and the inner diameter surface of the brake hole 720 is deepened, thereby gradually increasing the pressure applied to the first rotating shaft 113 by the tongue 721. The pressure acts as a damper for the rotation of the first rotating shaft 113, hindering the rotation of the first rotating shaft 113 until it can no longer rotate. The first traction disc 115 is locked in its rotational position, thereby locking the locking device 10 in the first dimension. The vertical traction length of the first traction wire 1153 associated with the first traction disc 115 in the endoscope guide tube is fixed, thus achieving locking of the endoscope lens in the first dimension.

[0136] When the endoscope locking device 10 needs to be unlocked in the first dimension, the knob 511 is rotated counterclockwise (or clockwise), causing the third rotating shaft 311 to rotate counterclockwise. The rotation of the third rotating shaft 311 synchronously drives the brake disc 313 to rotate, thereby reducing the rotation angle between the brake disc 313 and the first rotating shaft 113. This causes the depth of the wedge-shaped surface 3131 on the brake disc 313 against the tongue 721 to gradually decrease, eventually reaching a non-adhesive state. The wedge-shaped surface 3131 then breaks free from the gap between the tongue 721 and the inner diameter surface of the brake hole 720, thus allowing... The pressure applied by the tongue 721 towards the first rotating shaft 113 gradually decreases until it disappears (the pressure disappears when the wedge surface 3131 and the tongue 721 change from a fitted state to a non-fitted state). The locking device 10 disengages from the locked state in the first dimension and enters the unlocked state. The first traction disc 115 can rotate flexibly with the operator's operation of the first rotating wheel 111. The first traction wire 1153 associated with the first traction disc 115 can be flexibly wound and unwound under the traction of the first rotating wheel 111, thereby allowing the angle of the endoscope lens to be flexibly adjusted in the first dimension.

[0137] Between the locked and unlocked positions of the locking device 10 in the first dimension, the first rotating shaft 113 can be in different damping states by operating the control knob 511, thereby obtaining different tightness of the adjustment wheel according to the need to rotate the first rotating wheel 111. In this way, when adjusting the endoscope, it can be set to a suitable state as needed. When unlocked, the endoscope lens angle can be freely adjusted through the first rotating wheel 111. When locked, the endoscope is fixed in a fixed state and the lens angle will not change. If it is in the damping state between the two, it will provide the operator with the tactile feel of turning the wheel, thereby making it easy to operate.

[0138] When the endoscope locking device 10 needs to be locked in the second dimension, the operating handle 533 is operated clockwise, causing the cam 530 connected to the operating handle 533 to rotate clockwise to different angles. During the clockwise rotation, the cam 530 exerts increasing pressure on the tension plate 331. Since the tension plate 331 is a cantilever beam structure with different inner diameters along the circumference, during the compression of the tension plate 331 by the cam 530, the tension plate 331 begins to move inward along the radial direction of the second rotating shaft 133, thereby achieving the inner diameter surface of the tension plate 331 aligning with the second rotating shaft 133. The outer peripheral surface changes from a separated state to a fitted state, and the tightness of the fit gradually increases. This increased tightness of the fit increases the frictional force applied to the second rotating shaft 133. The cam 531 is positioned at the position with greater friction by the positioning device on the operating handle 533. Under the action of the frictional force, the second traction disc 135 is locked in its rotational position, thereby locking the locking device 10 in the second dimension. The lateral traction length of the second traction wire 1353 associated with the second traction disc 135 in the endoscope guide tube is fixed, thus locking the endoscope lens in the second dimension.

[0139] When the endoscope locking device 10 needs to be unlocked in the second dimension, the operating handle 533 is operated counterclockwise, causing the cam 530 connected to the operating handle 533 to rotate counterclockwise to different angles. During the counterclockwise rotation, the pressure of the cam 530 on the tension plate 331 gradually decreases, and the tightness of the fit between the inner diameter surface of the tension plate 331 and the outer peripheral surface of the second rotating shaft 133 gradually decreases. As a result, the friction force loaded on the second rotating shaft 133 gradually decreases until it disappears (the inner diameter surface of the tension plate 331 and the outer peripheral surface of the second rotating shaft 133 change from a fitted state to a separated state). The locking device 10 disengages from the locked state in the second dimension and enters the unlocked state. The second traction disc 135 can rotate flexibly with the operator's operation of the second rotating wheel 131. The second traction wire 1353 associated with the second traction disc 135 can be flexibly wound and unwound under the traction of the second rotating wheel 131, thereby allowing the endoscope lens to be flexibly adjusted in the second dimension.

[0140] In the locking and unlocking positions of the locking device 10 in the second dimension, the second rotating shaft 133 can be in different damping states by operating the operating handle 533, thereby obtaining different tightness of the adjustment wheel according to the need to rotate the second rotating wheel 131. In this way, when adjusting the endoscope, it can be set to a suitable state as needed. When unlocked, the endoscope lens angle can be freely adjusted by the second rotating wheel 131. When locked, the endoscope is fixed in a fixed state and the lens angle will not change. If it is in the damping state between the two, it will provide the operator with the desired feel for turning the wheel, thus making it easy to operate.

[0141] The locking device 10 of this application can bend and fix the distal curved part of the endoscope at any angle when the locking device 10 is working, and can also make individual adjustments to the observation angle of the endoscope lens in the first and second dimensions, thereby achieving the angular flexibility and stability of the endoscope lens during endoscopy and improving the efficiency of the operation.

[0142] The first embodiment described above is a preferred embodiment, and obviously, other variations are possible based on its basic principle. For example, the rotary wheel assembly 100 includes a first rotary wheel assembly 110, meaning the locking device 10 can only adjust the angle of the endoscope in one dimension. Of course, there are other possible variations. For example, the first rotary wheel 111 and the second rotary wheel 131, as mentioned above, are in opposite positions, rather than being at the same end as in this embodiment.

[0143] The second embodiment of this application provides another locking device for endoscope adjustment. The advantage of this embodiment is that the locking device has high flexibility in switching between locked and unlocked states and good adjustability.

[0144] The following is in conjunction with the appendix Figure 8 - Appendix Figure 12 The second embodiment of this application will be described in detail.

[0145] like Figure 8 The diagram shown is a cross-sectional view of the locking device 810 for endoscope adjustment provided in this embodiment; wherein, Figure 8 The top is the first end of the locking device 810, that is, one end of the first rotating wheel assembly 8100; Figure 8 Below is the second end of the locking device 810, which is close to the body (handle). The brake 8300 is mounted on the body (handle). In this figure, the locking device 810 is in an unlocked state. Figure 9 for Figure 8 A schematic diagram of the overall structure of the locking device 810 in the unlocked state. Figure 10 for Figure 8A schematic diagram of the overall structure of the locking device 810 in the locked state.

[0146] like Figure 8 As shown, the locking device 810 includes the following components or parts: a first rotating wheel assembly 8100; a brake 8300; a swing assembly 8500; and a handle 8700.

[0147] The arrangement of the above-mentioned components can be roughly described as follows: the first rotating wheel assembly 100 is located at the first end of the locking device 810 ( Figure 8 Above), the swing assembly 8500 is located in the middle of the locking device 810. Figure 8 (middle), the braking element 8300 is located in a separated manner at the second end of the locking device 810 ( Figure 8 (Lower left), the braking element 8300 is arranged on one side of the outer peripheral surface of the first traction disc 8150, which is a component of the first rotating wheel assembly 8100, and is located on one side of the swing direction of the first rotating wheel assembly 8100; by operating the first rotating wheel assembly 8100 in a swing manner, under the action of the swing component 8500, the braking element 8300 can be attracted or separated from the outer peripheral surface of the first traction disc 8150 in the first rotating wheel assembly 8100; when the braking element 8300 is attracted to the first traction disc 8150, it can provide the desired damping for the rotation of the first rotating wheel assembly 8100.

[0148] In this embodiment, the handle 8700 is actually the body of the locking device 810, providing a positioning basis for other components. It is called a handle because it serves as a handle in the overall structure of the endoscope. Its specific structure will be described later.

[0149] The locking device 810 for endoscope adjustment further includes: a second rotating wheel assembly 8200; the second rotating wheel assembly 8200 includes: a second rotating wheel 8210, a second rotating shaft 8230, and a second traction disc 8250.

[0150] The following is in conjunction with the appendix Figure 8 A detailed introduction to each component.

[0151] The first wheel assembly 8100 includes a first wheel 8110, a first shaft 8130, and a first traction disc 8150; the second wheel assembly 8200 includes a second wheel 8210, a second shaft 8230, and a second traction disc 8250.

[0152] The first rotating wheel 8110 is connected to the first end of the first rotating shaft 8130. In this embodiment, the first rotating wheel 8110 is fixedly connected to the first end of the first rotating shaft 8130, serving as an operating handle on the first rotating shaft 8130. In this embodiment, the first rotating wheel 8110 is fixedly disposed at the first end of the first rotating shaft 8130. Figure 8 Above); the first traction disc 8150 is located at the other end of the first rotating shaft 8130, that is, the second end of the first rotating shaft 8130 (above); Figure 8 Below); the second rotating wheel 8210 is connected to the first end of the second rotating shaft 8230. In this embodiment, the second rotating wheel 8210 is fixedly connected to the first end of the second rotating shaft 8230, and the second rotating shaft 8230 and the first rotating shaft 8130 are coaxial. In this embodiment, as a most likely arrangement, the coaxiality is achieved by the second rotating shaft 8230 being sleeved on the outer circumferential surface of the first rotating shaft 8130; the second traction disc 8250 is disposed near the first end of the second rotating shaft 8230. As can be seen from the figure, the second traction disc 8250 is disposed near the first end relative to the first traction disc 8150. Figure 8 (Above). Furthermore, the first rotating wheel 8110 is located closer to the first end of the second rotating wheel 8210, and the first rotating wheel 8110 has a boss extending towards the second end, while the second rotating wheel 8210 has a corresponding groove, allowing the boss to embed into the groove, thereby shortening the axial installation dimensions of the first rotating wheel 8110 and the second rotating wheel 8210. Of course, the coaxial arrangement of the first rotating shaft 8130 and the second rotating shaft 8230 can also be achieved in other ways, such as arranging them opposite each other from both ends. If this arrangement is adopted, the layout of the entire locking device will be significantly different from this embodiment, but its principle is not fundamentally different.

[0153] In this embodiment, the structures of the first traction disc 8150 and the second traction disc 8250 are the same as those of the first traction disc 115 and the second traction disc 135 in the first embodiment described above. This embodiment will not repeat the details. Please refer to the detailed description in the first embodiment for more information.

[0154] The following describes the braking component 8300 and the swing assembly 8500; due to their close relationship, there is some overlap in the description. Please refer to... Figure 8 You can also refer to Figure 9 The illustration.

[0155] The braking component 8300 includes: a braking component body 8310; and a braking component adsorption part 8330.

[0156] The swing assembly 8500 includes: a swing shaft 8510; a swing disk 8530; and a support 8550. The swing shaft 8510 is coaxial with the first rotating shaft 8130 and the second rotating shaft 8230. In this embodiment, as a most likely arrangement, the coaxiality is achieved by the first rotating shaft 8130 and the second rotating shaft 8230 being sleeved on the outer circumferential surface of the swing shaft 8510. The swing shaft 8510 is a hollow swing shaft. The first rotating wheel assembly 8100, the second rotating wheel assembly 8200, and the swing disk 8530 are connected to the machine body via the swing shaft 8510, and are connected to it in a swinging manner. The swing disk 8530 is sleeved on the outer circumferential surface of the first rotating shaft 8130, and the swing disk 8530 is arranged at the gap position between the axial direction of the first traction disk 8150 and the second traction disk 8250. Figure 8 (In the middle), through the swing of the swing shaft 8510, the first rotating wheel assembly 8100 and the second rotating wheel assembly 8200 swing synchronously. The swing shaft 8510 can simultaneously limit the swing range of the first rotating wheel assembly 8100 and the second rotating wheel assembly 8200. The detailed description of the structure of the swing disk 8530 will be introduced after the structure of the brake 8300 is introduced. It should be noted here that the swing shaft 8510 can actually be a virtual axis of the swing disk 8530, that is, the swing disk 8530 itself provides support for the second rotating shaft 8230 from the outer peripheral surface, and the central axis of the swing disk 8530 (the actual central axis is hollow) is used as the swing shaft 8510. The axial end of the swing shaft 8510 is also connected to the support 8550 ( Figure 8 Below, the support 8550 provides a mounting base for the axial ends of the swing shaft 8510, swing disk 8530, first rotating wheel assembly 8100, and second rotating wheel assembly 8200, thus supporting these components; the bottom surface of the support 8550 has a gap with the machine body, allowing the components supported above it to have a certain swing range. In an embodiment of this application, as one possible approach, the support 8550 is a disk with the same radius as the second traction disk 8250, and its second end ( Figure 8 A cutting surface is provided at the bottom (near one end of the machine body), and the gap between the cutting surface and the machine body can limit the swing range of the first rotating wheel assembly 8100.

[0157] Combination Figure 12As illustrated, to achieve the swing, connecting rods 8537 are respectively connected to both sides of the swing disk body 8531. The lower end of the connecting rod 8537 is provided with a pivot hole 8538. The pivot shaft 8539 is connected to the pivot seat 8720 through a clearance fit with the pivot hole 8538. The pivot seat 8720 is fixed to the handle 8700 body. In this way, the pivot seats 8720 located on both sides of the support seat 8550 support the swing assembly 8500 through the connecting rods 8537, so that the swing assembly 8500 can swing about the pivot shaft 8539 as the rotation axis. Its swing range is limited by the gap between the support seat 8550 and the handle 8700 body.

[0158] The handle 8700, named as such because it is the handle of an endoscope, is equivalent to the body providing the positioning base in this application. The handle 8700 is generally designed as two interlocking covers that can be disassembled according to assembly and repair needs. For the endoscope locking device of this application, the relevant structures provided by the body are mainly the fixing post 8710 and the pivot seat 8720; the pivot seat 8720 is fixed on the body and is used to provide a support base for the swing disk 8530 to swing.

[0159] In this embodiment, the handle 8700 is a hollow cylindrical shell made of plastic. The fixing post 8710 is located on the inner surface of the handle 8700 shell. The fixing post 8710 is separately disposed on the side opposite to the location of the brake member 8300. The fixing post 8710 can attract and separate from the protruding part 8535 of the swing disk, so that when the locking device 810 does not need to be locked, it can obtain a working position where the first rotating shaft 8130 and the second rotating shaft 8230 can rotate freely by leaning against the fixing post 8710. In this embodiment, as one of the most likely implementations, the fixing post 8710 is a rectangular thin plate with magnetism. The second end of the rectangular thin plate 8710 is fixed to the body (i.e., the inner surface of the handle 8700), and its first end achieves attraction and separation from the protruding part 8535 of the swing disk. At this first end position, a magnetic attraction surface or a surface that can be attracted by a magnetic object can be provided.

[0160] Figure 11 A structural diagram of the brake element 8300 is shown below. (The following is in conjunction with...) Figure 11 For a detailed introduction to the brake component 8300, please refer to [link / reference]. Figure 8 , Figure 9 .

[0161] As previously described, the braking component 8300 includes: a braking component body 8310; and a braking component adsorption part 8330.

[0162] The brake element 8300 is separately disposed on one side of the swing direction of the first rotating wheel assembly 8100. The brake disc body 8310 has a wedge-shaped structure, with the surface facing the first rotating wheel assembly 8100 being an inclined surface. This facilitates contact with the inclined outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250. The end of the brake element body 8310 is provided with a brake element adsorption part 8330, which can adsorb the outer peripheral surfaces 8150 and 8250 of the first and second traction discs. The adsorption principle is most likely magnetic adsorption, but other adsorption methods are also possible, such as using a surface with Velcro. The adsorption surface of the brake element adsorption part 8330 is an inclined surface. When the brake element 8300 is in contact with the outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250... During adsorption, the inclined surface allows the brake element 8300 to have a set adsorption area when it is attached to the outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250. In this embodiment, the outer peripheral surfaces of the first traction disc and the second traction disc are both made of magnetically adsorbable metal material, and the brake adsorption part 8330 is a magnetic body. When the first rotating wheel 8110 and the second rotating wheel 8210 are swung, the first traction disc 8150, the second traction disc 8250, and the swing disc 8530 can swing under the drive of the swing shaft 8510. When the first traction disc 8150 and the second traction disc 8250 swing to a certain angle, the brake element 8300 can magnetically adsorb the first traction disc 8150 and the second traction disc 8250, thereby providing damping for the rotation of the first rotating shaft 8130 and the second rotating shaft 8230.

[0163] Figure 12 The following is a structural diagram of the oscillating disk 8530. Figure 12 For a detailed explanation of the specific structure of the oscillating disk 8530, please refer to [link / reference]. Figure 8 .

[0164] like Figure 12 As shown, the swing disk 8530 includes: a swing disk body 8531; a swing disk center hole 8533; a swing disk protrusion 8535; a connecting rod 8537; a pivot hole 8538; and a pivot shaft 8539 (please refer to...). Figure 8 ).

[0165] To better understand, let's first introduce the swing shaft 8510 and the swing disk 8530. The swing shaft 8510 is the central axis of the swing disk 8530 (see reference). Figure 8In the axial direction, the swing disk 8530 is positioned at the axial gap between the first traction disk 8150 and the second traction disk 8250. In the embodiments of this application, as one of the most likely arrangements, the swing disk 8530 clamps the first rotating shaft 8130 from the outside. Through the connecting rod 8537 connected to the swing disk 8530, the swing assembly 8500 can swing around the pivot shaft 8539, thereby causing the entire first rotating wheel assembly 8100 and the second rotating wheel assembly 8200 to swing as a whole. The swing disk body 8531 is a hollow disc with a central hole 8533 inside, through which the swing disk 8530 can externally clamp the first rotating shaft 8130. A swing disk protrusion 8535 is provided on the outer circumferential surface of the swing disk body 8531, positioned opposite the fixing post 8710. The swing disk protrusion 8535 is made of a material with an adsorption effect, capable of adsorbing onto the fixing post 8710. A connecting rod 8537 is also provided on the outer circumferential surface of the swing disk body 8531. The connecting rod 8537 and the swing shaft 8510 are both perpendicular to the surface of the handle 8700 body. One end of the connecting rod 8537 is provided with a pivot hole 8538, and a pivot shaft 8539 is fitted into the pivot hole 8538 with clearance. The pivot shaft 8539 is connected to the pivot seat 8720 of the handle 8700 body. The swing mechanism 8500 can be swung through the pivot shaft 8539, and the first rotating wheel assembly 8100 and the second rotating wheel assembly 8200 swing accordingly. Moreover, under the constraint of the support seat 8550, its swing range is limited to a certain angle range.

[0166] In this embodiment of the application, as one of the most likely arrangements, the swing disk 8530, the first traction disk 8150, and the second traction disk 8250 are disks with similar radii. The connecting rods 8537 are symmetrically arranged on the outer circumferential surface of the swing disk body 8531. The protrusion of the swing disk 8535 is a component containing magnetic material, which can be attracted to the metal fixing column 8710.

[0167] When the endoscope is in operation, the first rotating wheel 8110, the second rotating wheel 8210, and the swing shaft 8510 are oscillated by moving them, thereby causing the first rotating wheel assembly 8100 and the second rotating wheel assembly 8200 to oscillate. During the oscillation, the adsorption part 8330 of the brake element adheres to and separates from the outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250, thereby providing damping for the rotation of the first rotating shaft 8130 and the second rotating shaft 8230. Specifically, when the oscillation reaches the outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250... When the outer peripheral surface is adsorbed (the protrusion 8535 of the swing disk separates from the fixed post 8710), the adsorption force of the brake adsorption part 8330 can provide damping for the rotation of the first rotating shaft 8130 and the second rotating shaft 8230; when the swing disk protrusion 8535 adsorbs the fixed post 8710 (the brake adsorption part 8330 separates from the outer peripheral surface of the first traction disk 8150 and the outer peripheral surface of the second traction disk 8250), the fixed post 8710 can create a stable adjustment state for the entire first rotating wheel assembly 8100, second rotating wheel assembly 8200, and swing assembly 8500. The above adsorption effect can also simultaneously adsorb and position the main body of the locking device 810 composed of the swing mechanism 8500, the first rotating wheel assembly 8100, and the second rotating wheel assembly 8200, so that the locking device 810 is in a stable unlocked state and a locked state.

[0168] The following are key references Figure 9 , Figure 10 The working process of the locking device 810 is described in detail.

[0169] Figure 9 It shows Figure 8 A schematic diagram of the locking device 810 in the unlocked state. Figure 10 It shows Figure 8 A schematic diagram of the locking device 810 in the locked state. See below for reference. Figures 8 to 10 This section briefly introduces the working process of the locking device 810, focusing on the operation process of switching between the locked and unlocked states.

[0170] When it is necessary to lock the endoscope locking device 810, force is applied by the first rotating wheel 8110 and the second rotating wheel 8210, causing the main body of the locking device 810 to rotate counterclockwise by a certain angle (e.g., Figure 9(Showing the movement from position A to position B), the first rotating wheel 8110 and the second rotating wheel 8210 drive the swing shaft 8510 to swing around the machine body, simultaneously driving the first traction disc 8150, the second traction disc 8250, and the swing disc 8530 to swing counterclockwise in sync. This causes the protruding part 8535 of the swing disc to separate from the fixed post 8710, and the outer peripheral surfaces of the first traction disc 8150 and the second traction disc 8250 to contact and adhere to the brake adsorption part 8330; when the brake adsorption part 8330 and the first traction disc 8510 contact the brake adsorption part 8530, the first traction disc 8510 will rotate counterclockwise. 150. When the second traction disc 8250 is engaged, the braking element 8300 provides damping for the rotation of the first rotating shaft 8130 and the second rotating shaft 8230. Due to this resistance, the first rotating shaft 8130 and the second rotating shaft 8230 cannot rotate, and the first traction disc 8150 and the second traction disc 8250 are locked in their respective rotational positions. The locking device enters a locked state, and the traction length of the traction wire associated with the traction disc in the vertical and horizontal directions within the endoscope guide tube is fixed, thus achieving endoscope lens angle locking. Please refer to... Figure 9 , Figure 10 The above process is Figure 9 Change to Figure 10 It can be seen that the braking component 8300 is... Figure 9 When positioned, it did not contact the first traction disc 8150 or the second traction disc 8250. Figure 10 When in position, it contacts the first traction disc 8150 and the second traction disc 8250.

[0171] When it is necessary to unlock the endoscope locking device 810, force is applied by the first rotating wheel 8110 and the second rotating wheel 8210, causing the main body of the locking device 810 to swing clockwise by a certain angle (e.g., Figure 10 (As shown from position B to position A), the first rotating wheel 8110 and the second rotating wheel 8210 drive the swing shaft 8510 to swing around the machine body, simultaneously driving the first traction disc 8150, the second traction disc 8250, and the swing disc 8530 to swing clockwise in sync. This causes the first traction disc 8150 and the second traction disc 8250 to separate from the brake 8300, and the protrusion 8535 of the swing disc contacts and adheres to the fixed post 8710. When the protrusion 8535 of the swing disc adheres to the fixed post 8710, the first rotating shaft 8130 and the second rotating shaft 8230 are in a rotatable free state. The locking device disengages from the above-mentioned locked state and enters the above-mentioned unlocked state. The first traction disc 8150 and the second traction disc 8250 can rotate flexibly with the operator's rotation operation of the first rotating wheel 8110 and the second rotating wheel 8210. The traction wire associated with the above-mentioned traction disc can be flexibly wound and unwound under the traction of the traction disc, thereby allowing the angle of the endoscope lens to be flexibly adjusted. Please refer to Figure 9 , Figure 10 The above process is from Figure 10 Change to Figure 9 It can be seen that the braking component 8300 is... Figure 10 When in position, it contacts the first traction disc 8150 and the second traction disc 8250, until... Figure 9 When in position, it does not contact the first traction disc 8150 or the second traction disc 8250.

[0172] The second embodiment described above is a preferred embodiment, and obviously, other variations are possible based on its fundamental principle. For example, the locking device 810 for endoscope adjustment includes a first rotating wheel assembly, meaning the locking device can only adjust the endoscope angle in one dimension. Of course, there are other possible variations. For example, the first rotating wheel 8110 and the second rotating wheel 8130, as mentioned earlier, are in opposite positions, rather than being at the same end as in this embodiment.

[0173] Corresponding to the second embodiment described above, the third embodiment of this application provides an endoscope, as shown in the attached drawing. Figure 13 Combined with the appendix Figure 8 - Appendix Figure 12 Explain its structure and working process.

[0174] In this embodiment, components with the same function as those in the second embodiment are named in the same way as possible to facilitate understanding; however, although the third embodiment and the second embodiment have common innovative points, there are still significant differences. Therefore, the description of this embodiment shall be based on the naming provided in this embodiment, and there is no need to force a correspondence with the second embodiment.

[0175] like Figure 13 The diagram shown is a schematic representation of the endoscope structure device 2 provided in this embodiment.

[0176] The following is in conjunction with the appendix Figure 13 The third embodiment of this application is described in detail.

[0177] like Figure 13 As shown, this is a schematic diagram of the cross-sectional structure of the endoscope 2 provided in this embodiment; wherein, Figure 13 The left side is the rear end of the endoscope, which is one end of the locking device 810 and the light source assembly 20. The rear end of the endoscope is the end that the operator holds during the actual surgical procedure. Figure 13 The right side of the endoscope structure is the front end, namely one end of the lens 70 and the flexible part 80. This front end of the endoscope is used for manipulation during surgery via the movement of the flexible part to visualize lesions in relevant areas. In this figure, the locking device 810 is in the unlocked state. In the following description, it will be... Figure 13 The left side is called the rear. Figure 13 The right side is referred to as the front.

[0178] like Figure 13 As shown, the endoscope structure device 2 includes: a locking device 810; a light source assembly 20; a traction wire 30; a suction tube 40; a flushing tube 50; an aviation connector 60; a lens 70; a flexible part 80; a catheter 90; and an 8700-handle.

[0179] The light source assembly 20 and the locking device 810 are both embedded in the handle 8700. The handle 8700 is used by the operator to hold the endoscope. The light source assembly 20 provides illumination for the lens 70 during observation. The handle 700 is located at the rear end of the endoscope 2. Figure 13 (Left side), the flexible part 80 and the lens 70 are located at the front end of the endoscope 2 ( Figure 13 (Right side), the two are connected to each other via a catheter 90. During minimally invasive surgery, typically, the tip of the endoscope 2 is positioned... Figure 13 In its unlocked state, the catheter 90 is pushed along the patient's cavity to the surgical site. The catheter 90 internally encloses a locking device 810 connected to the traction wire 30 of the lens 70. This enclosure is not a tight wrap, but rather provides a dedicated channel for each traction wire, with a suitable radial dimension. The catheter 90 itself is made of a flexible material, allowing it to adapt to the patient's curved cavities. The flexible portion 80 adjusts the observation angle of the lens 70 at the lesion site. The handle 8700 is controlled by the surgeon, who can externally manipulate the locking device 810 using a rotating assembly, thereby enabling observation of the lesion site inside the patient's body from different angles.

[0180] The endoscope structure 2 can achieve arbitrary angle bending of the flexible traction wire 30 through the locking device 810. The locking device 810 adjusts the length of the first traction wire in the first traction disc 8150, thereby achieving angle adjustment of the lens 70 in a fixed position in the first dimension. For a detailed process of adjusting the locking and unlocking working states of the locking device 810 using the rotating wheel assembly, please refer to Embodiment 2, which will not be elaborated further here.

[0181] Figure 13 front end ( Figure 13 The upper right corner also shows the suction tube 40, the flushing tube 50, and the aviation connector 60, which work in conjunction with the lens 70. The suction tube 40 and the flushing tube 50 are used to remove obstructions from the viewing area of ​​the lens 70, ensuring a clear field of view and facilitating direct visualization of lesions in relevant areas. The aviation connector 60 is used to connect the required wires.

[0182] Corresponding to the first embodiment described above, the fourth embodiment of this application also provides a locking device; the purpose of providing this embodiment is to extend the principle of the first embodiment to other possible applications, rather than limiting it to endoscopes. Of course, the principle of the second embodiment can also be extended to the application where needed; this embodiment is only provided as an illustration.

[0183] The following combination Figures 1-7 The structure and working process are explained. In this embodiment, components with the same function as those in the first embodiment are named in the same way as possible for ease of understanding; however, although the fourth embodiment and the first embodiment share common innovative points, there are still significant differences. Therefore, the description of this embodiment shall be based on the naming provided in this embodiment, and there is no need to force a correspondence with the first embodiment.

[0184] The locking device 10' is typically used in testing scenarios. Referring to the process described in Embodiment 1, the first traction disc 115 and the second traction disc 135 in the rotating wheel assembly 100 are replaced with a first functional disc 115' and a second functional disc 135' to enable various possible adjustment functions. It should be understood that the structure of the first functional disc 115' and the second functional disc 135' can be adjusted according to the function and application scenario requirements of the locking device 10'. This embodiment does not impose specific limitations.

[0185] The locking device 10' includes: a first rotating wheel 111, a first rotating shaft 113, and a brake 300; the first rotating wheel 111 is connected to the first end of the first rotating shaft 113; a first function disk 115' is provided on the first rotating shaft 113; the brake 300 is used to provide desired damping for the rotation of the first rotating shaft 113, and the rotation of the first function disk 115' is used to realize a set adjustment function, such as adjusting the first traction wire mentioned in the previous embodiment, or it can realize other adjustment functions, such as the rotation of the first function disk 115' itself can realize the adjustment function of a certain device, such as the focal length of a microscope; here, the specific adjustment function is not limited.

[0186] In one possible implementation, the locking device 10' further includes: a body and a brake drive, the brake drive including a first brake assembly drive, the brake including a first brake assembly; the first function disk is disposed at the middle position of the first rotating shaft, and the second end of the first rotating shaft is disposed in the body;

[0187] The first braking assembly has a third rotating shaft disposed within the first rotating shaft. The third rotating shaft rotates independently of the rotation of the first rotating shaft. A brake disc is connected to the second end of the third rotating shaft. The brake disc is disposed in a brake hole on one side of the machine body. A tongue extending spirally along the circumference is disposed on the inner diameter of the brake hole. A wedge-shaped surface is disposed on the end face of the brake disc. The wedge-shaped surface cooperates with the tongue disposed in the brake hole and can enter the gap between the tongue and the inner diameter surface of the brake hole.

[0188] The first brake assembly drive is disposed at the first end of the third rotating shaft. By manipulating the first brake assembly drive, the rotation angle of the brake disc can be adjusted by means of the third rotating shaft. By the wedge-shaped surface on the brake disc being in contact with or not in contact with the tongue, and the degree of contact, different degrees of compression can be applied to the first rotating shaft by the tongue, thereby achieving the desired damping for the rotation of the first rotating shaft.

[0189] In one possible implementation, the locking device 10' further includes: a second rotating wheel, a second rotating shaft, a second braking element, and a second braking element drive element;

[0190] The second rotating wheel is connected to the first end of the second rotating shaft, and the first and second rotating shafts are coaxial. The second rotating shaft is sleeved on the outer circumferential surface of the first rotating shaft, and the second rotating shaft rotates independently of the rotation of the first rotating shaft. A second functional disk is provided at the second end of the second rotating shaft. The second rotating shaft has a portion extending out of the housing of the locking device. The second braking element is a tensioning plate with a cantilever beam structure. The tensioning plate is positioned on the outer surface of the housing of the locking device and is arranged around the portion of the second rotating shaft extending out of the housing.

[0191] The second braking drive component radially compresses the tensioning plate, causing it to contract radially. This causes the inner diameter surface of the tensioning plate to adhere to the outer circumferential surface of the second rotating shaft, thereby applying frictional force to the second rotating shaft. By varying degrees of compression, the tightness of the fit between the inner diameter surface of the tensioning plate and the outer circumferential surface of the second rotating shaft can be adjusted, thus applying different frictional forces to the second rotating shaft. The rotation of the second functional disk adjusts the second traction wire, thereby adjusting the observation angle of the endoscope in a second dimension, which is in a different directional dimension from the first dimension.

[0192] In one possible implementation, the locking device 10' further includes: a swing assembly; the first rotating wheel, the first rotating shaft, and the first functional disk form a whole first rotating wheel assembly, the first rotating wheel assembly is connected to the machine body through a swing shaft provided by the swing assembly, and can swing, the swing assembly can limit the swing range of the first rotating wheel assembly; the brake is separately disposed on one side of the swing direction of the first rotating wheel assembly; by swinging the first rotating wheel assembly, the brake can be attracted and separated from the outer peripheral surface of the first functional disk, and when the brake is attracted to the first functional disk, the brake can provide damping for the rotation of the first rotating shaft.
