Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a locking device for adjusting an endoscope, an endoscope, and a locking device. Background Technology

[0002] With the reform of the national medical system, the advancement of medical technology, 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 an endoscope locking device 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 invention provides a locking device for endoscope adjustment, addressing the problems of insufficient operational stability, low precision, and inflexible bending angles in existing endoscope locking devices. This invention also provides an endoscope. Furthermore, this invention provides a locking device.

[0006] According to an embodiment of the present invention, a locking device for endoscope adjustment is provided, comprising: a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc drive assembly;

[0008] In one possible implementation, the locking device for endoscope adjustment includes a second rotating wheel and a second rotating shaft; the second rotating wheel is connected to a first end of the second rotating shaft, and the second rotating shaft and the first rotating shaft are coaxial; a second traction disc is provided at a second end of the second rotating shaft, and a brake disc is located on at least one side of the second traction disc relative to the first traction disc; adjusting the brake disc so that it fits against at least one side of the first traction disc, and adjusting the tightness of the fit, also adjusts the fit and tightness of the fit between the brake disc and the second traction disc relative to at least one side of the first traction disc, thereby providing desired damping for the rotation of the second rotating shaft; the second traction disc adjusts the second traction wire of the endoscope by rotating itself, and the second traction wire controls the observation angle of the endoscope in a second dimension, which is in a different directional dimension from the first dimension.

[0010] In one possible implementation, the locking device for endoscope adjustment further includes a brake disc comprising a brake disc body having a wedge-shaped body and a support portion extending from the brake disc body. A positioning hole is provided at one end of the support portion away from the brake disc body, and the positioning hole is rotatably fitted onto a fixing post of the housing of the locking device. By adjusting the angle at which the brake disc swings around the fixing post, the tightness of the fit between the brake disc body and at least one side of the first traction disc and the second traction disc relative to at least one side of the first traction disc can be adjusted.

[0011] In one possible implementation, the locking device for endoscope adjustment further includes an elongated hole on the outer peripheral surface of the brake disc;

[0012] The brake disc drive assembly includes a drive member coaxially arranged with the first rotating shaft. The drive member also has a cantilever connected to the drive member body and extending radially to one side. An axially extending cantilever column is disposed on the cantilever, and the cantilever column is inserted into an elongated hole provided on the brake disc. When the drive member rotates, the cantilever column slides in the elongated hole, thereby driving the brake disc to swing around the fixed column, thereby adjusting the angle of the brake disc swinging around the fixed column.

[0013] In one possible implementation, the locking device for endoscope adjustment further includes a lever having a length significantly larger than the diameter of the drive member, one end of the lever being fixedly connected to the drive member, and the other end extending radially and providing an operating surface for easy manipulation; by manipulating the lever, the drive member can be rotated.

[0015] In one possible implementation, the locking device for endoscope adjustment further includes a spacer plate disposed between at least one side of the first traction disc and at least one side of the second traction disc relative to the first traction disc.

[0016] In one possible implementation, the locking device for endoscope adjustment further includes a brake disc and a brake disc drive assembly divided into two groups, which respectively provide the damping to the first rotating shaft and the second rotating shaft.

[0017] The present invention also provides an endoscope having a locking device for adjustment; the locking device includes a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc drive assembly;

[0019] The first traction disc adjusts the first traction wire of the endoscope by rotating itself, thereby adjusting the observation angle of the endoscope in the first dimension; through this adjustment and in combination with the damping provided by the brake disc, the endoscope can be rotated to and remain at the required observation angle in the first dimension as needed.

[0020] In one possible implementation, the endoscope further includes a second rotary wheel and a second rotating shaft; the second rotary wheel is connected to the first end of the second rotating shaft, and the second rotating shaft and the first rotating shaft are coaxial; a second traction disc is provided at the end of the second rotating shaft, and a brake disc is located on at least one side of the second traction disc relative to the first traction disc; adjusting the brake disc so that it fits against at least one side of the first traction disc, and adjusting the tightness of the fit, also adjusts the fit and tightness of the brake disc against at least one side of the second traction disc relative to the first traction disc, thereby providing desired damping for the rotation of the second rotating shaft;

[0021] The second traction disc adjusts the second traction wire of the endoscope by rotating itself, thereby controlling the observation angle of the endoscope in the second dimension. Through this adjustment and in combination with the damping provided by the brake disc, the endoscope can be rotated to and remain at the required observation angle in the second dimension as needed. The second dimension is in a different directional dimension from the first dimension.

[0022] The present invention also provides a locking device, including a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc drive assembly;

[0023] The first rotating wheel is connected to the first end of the first rotating shaft; a first functional disc is provided at the second end of the first rotating shaft; the brake disc is provided on at least one side of the first functional disc, and the brake disc can be adjusted by the brake disc drive assembly to make the brake disc fit against at least one side of the first functional disc, and the tightness of the fit can be adjusted, thereby providing the desired damping for the rotation of the first rotating shaft.

[0025] In one possible implementation, the brake disc in the locking device includes a wedge-shaped brake disc body and a support portion extending from the brake disc body. A positioning hole is provided at one end of the support portion away from the brake disc body, and this positioning hole is rotatably fitted onto a fixing post of the housing of the locking device. By adjusting the angle at which the brake disc swings around the fixing post, the tightness of the fit between the brake disc body and at least one side of the first functional disc and at least one side of the second functional disc relative to the first traction disc can be adjusted.

[0026] In one possible implementation, in the locking device, at least one side of the first functional disc and at least one side of the second functional disc relative to the first traction disc are disposed opposite each other, with a predetermined gap between them; adjusting the brake disc can adjust the depth to which the brake disc body, which is a wedge, is inserted into the gap, thereby making the brake disc fit with at least one side of the first functional disc and at least one side of the second functional disc relative to the first traction disc, and adjusting the tightness of the fit.

[0027] This invention provides a locking device for adjusting an endoscope. The locking device includes a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc drive assembly. The first rotating wheel is connected to a first end of the first rotating shaft. A first traction disc is disposed at a second end of the first rotating shaft. The brake disc is disposed on at least one side of the first traction disc. The brake disc drive assembly allows adjustment of the brake disc, enabling it to engage with at least one side of the first traction disc, and the tightness of the engagement can be adjusted, thereby providing desired damping for the rotation of the first rotating shaft. Because the brake disc drive assembly provides controllable damping on at least one side of the first traction disc on the first rotating shaft, the distal curved portion of the endoscope can be bent and fixed at any angle during operation of the locking device. This ultimately achieves angular flexibility and stability of the endoscope lens during endoscopic operation, improving surgical efficiency. Attached Figure Description

[0060] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0061] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0063] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0064] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0065] In related technologies, the locking device of the endoscope usually uses a locking handwheel to adjust the lens. However, during operation, there are many problems such as insufficient stability, low precision, and inflexible bending angle when operating the lens. In view of this, this application provides a locking device for endoscope adjustment, comprising a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc drive assembly. The first rotating wheel is connected to a first end of the first rotating shaft; a first traction disc is disposed at a second end of the first rotating shaft; the brake disc is disposed on at least one side of the first traction disc, and the brake disc drive assembly can adjust the brake disc to fit against at least one side of the first traction disc, and the tightness of the fit can be adjusted, thereby providing the desired damping for the rotation of the first rotating shaft; the first traction disc adjusts the first traction wire of the endoscope by rotating itself. By adjusting the damping of the first rotating shaft, the first rotating shaft, under different magnitudes of frictional force, realizes the control of the first traction wire by the first traction disc, thereby realizing the adjustment of the angle and position of the traction wire on the endoscope lens. This is beneficial for the bending and fixing of the distal curved part of the endoscope at any angle, ultimately achieving the angular flexibility and stability of the endoscope lens during endoscope operation, and improving the efficiency of the surgery.

[0066] The following describes several alternative implementations of this disclosure with reference to the accompanying drawings. Those skilled in the art should understand that the following implementations are merely illustrative and not an exhaustive list. Based on these implementations, those skilled in the art may replace, splice, or combine certain features or examples, and these should still be considered as the disclosure content of this disclosure.

[0067] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The first embodiment of this application is described in detail.

[0068] like Figure 1 The diagram shown is a cross-sectional view of the locking device 10 for an endoscope provided in this embodiment; wherein, Figure 1 The left side is the second end of the locking device 10, that is, one end of the brake disc 300; Figure 1 The right side is the first end of the locking device 10, that is, the end where the rotating wheel assembly 100 is provided; in this figure, the locking device is in a locked state. Figure 2 for Figure 1 A schematic diagram of the locking device 10 in the unlocked state. Figure 3 for Figure 1 A schematic diagram of the locking device 10 in the locked state. Figure 2 , 3 All Figure 1 The diagram shows the structure of the locking device 10 rotating counterclockwise so that the second end of the locking device 10, i.e., the brake disc 300, faces outward from the paper.

[0069] like Figure 1 As shown, the locking device 10 includes the following components or parts: a rotating wheel assembly 100; a brake disc 300; a brake disc drive assembly 500; and a handle 700.

[0070] The arrangement of the above-mentioned components can be roughly described as follows: the brake disc 300 is located at the second end of the locking device 10 ( Figure 1 (Left side), the brake disc drive assembly 500 is located in the middle of the locking device 10 ( Figure 1 (middle), the rotating wheel assembly 100 is located at the first end of the locking device 10 ( Figure 1 On the right side, the wheel assembly 100 contacts the brake disc 300 via a first traction disc 115 and a second traction disc 135. The brake disc 300 is positioned between at least one side (e.g., a first side) of the first traction disc 115 and at least one side (e.g., a second side) of the second traction disc 135 relative to the first traction disc. The brake disc 300 is connected to the brake disc drive assembly 500 via a drive member 510. Under the action of the brake disc drive assembly 500, the tightness of the contact between the brake disc 300 and the side of the traction disc can be adjusted, thereby providing the desired damping for the rotation of the wheel assembly 100.

[0071] The handle 700 is actually the body of the locking device 10, 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, and its specific structure will be explained later.

[0072] The rotating wheel assembly 100 includes: a first rotating wheel assembly 110; a second rotating wheel assembly 130; a separator 150; and an elastomer 170.

[0073] The following details each component or part.

[0074] The rotating wheel assembly 100 includes a first rotating wheel assembly 110, a second rotating wheel assembly 130, an isolation plate 150, and an elastomer 170. The first rotating wheel assembly 110 includes a first rotating wheel 111, a first rotating shaft 113, and a first traction disc 115. The second rotating wheel assembly 130 includes a second rotating wheel 131, a second rotating shaft 133, and a second traction disc 135. The elastomer 170 can be a soft rubber pad, a disc spring, a compression spring, or other elastic parts; this embodiment does not impose a specific limitation.

[0075] The first rotating wheel 111 is connected to the first end of the first rotating shaft 113, serving as an operating handle mounted on the first rotating shaft 113. In this embodiment, the first rotating wheel 111 is located at the first end of the first rotating shaft 113. Figure 1 (Right side); the first traction disc 115 is located at the other end of the first rotating shaft 113, that is, the second end of the first rotating shaft 113. Figure 1 (Left side); the second rotating wheel 131 is connected to the first end of the second rotating shaft 133, and the second rotating shaft 133 and the first rotating shaft 113 are coaxial. In this embodiment, as the 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; the second traction disc 135 is 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 1 At the right side position, a spacer 150 is provided between the first traction disc 115 and the second traction disc 135. An elastic body 170 is provided on the surface of the first traction disc 115 (first side) and the second traction disc 135 (second side) that are in contact with the brake disc 300. The elastic body 170 can be used to contact and compress with the brake disc body 310. In addition, 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 to the second end, while the second rotating wheel 131 is provided with a corresponding groove, so that the boss is embedded in the groove, thereby shortening the axial installation size 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 adopted in other different ways. For example, they can be arranged opposite each other from both ends. If this arrangement is adopted, the layout of the entire locking device is significantly different from that of this embodiment, but its principle is not fundamentally different.

[0076] Please see Figure 6 The first traction disc 115 has a fixed position for the first traction wire 1153. By rotating the first traction disc 115, the extension distance of the first traction wire 1153 can be adjusted. The first traction wire 1153 can also pull the endoscope lens, so that the endoscope is at a suitable angle in the dimension controlled by the first traction wire 1153. Figure 6 A structural diagram of the first traction disc 115 is shown. The diagram also shows a first rotating shaft 113 connected to the first traction disc 115. The following is combined with... Figure 6 For a detailed description of the specific structure of the first traction disc 115, please refer to [reference needed]. Figure 1 .

[0077] Figure 6 As 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.

[0078] The first traction disc 115 has 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.

[0079] 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.

[0080] Similar to the first traction disc, the second traction disc 135 has a similar structure, the difference being that it is positioned at the second end of the second rotating shaft 133. This second traction disc 135 is used to fix the second traction wire. By rotating the second traction disc 135, the extension and retraction of the second traction wire can be adjusted, thereby adjusting the observation angle of the endoscope in the second dimension. Specifically, the rotation of the second traction disc 135 can control the winding and retraction of the second traction wire in the second dimension, thereby adjusting its extension distance. The traction wire is embedded in the endoscope's guide tube. The two ends of the traction wire are respectively positioned at the curved end of the endoscope guide tube and the end of the traction disc. One end is connected to the traction disc, and the other end is fixed in the guide tube. Generally, after one end of a traction wire is pulled by the traction disc, when the traction disc rotates, due to the flexibility of the guide tube, the traction wire drives the rotation of the flexible portion at the distal end of the guide tube, thereby causing the endoscope lens to rotate in a certain dimension (up and down, or left and right), allowing the endoscope lens to deflect at a certain angle and change the observation angle.

[0081] The following describes the brake disc 300 and the brake disc drive assembly 500; since the two are closely related, there is some overlap in the content of the description.

[0082] The brake disc 300 includes: a brake disc body 310; a support portion 330; an elongated hole 350; and a positioning hole 370.

[0083] The brake disc drive assembly 500 includes: a drive member 510 and a lever 530. The drive member 510 is located at the second end of the brake disc drive assembly 500. Figure 1 The lever 530 is located at the first end of the brake disc drive assembly 500 (middle to left). Figure 1 (Middle to right), the lower end of the lever 530 is fixedly connected to the outer peripheral surface of the drive body 515 in the drive member 510. The lever 530 has a length that is significantly larger than the diameter of the drive member 510, and the upper end of the lever 530 extends out in the radial direction. Figure 1 The upper end provides an operating surface for easy manipulation. A detailed description of the structure of the drive element 510 will follow after the description of the structure of the brake disc 300.

[0084] The handle 700, named as such because it serves as the handle of an endoscope, functions in this application as the body providing the positioning base. The handle 700 is generally designed as two interlocking covers that can be disassembled for assembly and repair needs. For the endoscope locking device of this application, the main structure provided by the body is the fixing post 710. In this embodiment, the handle 700 is a hollow cylindrical shell made of plastic, and the fixing post 710 is located on the inner surface of the handle 700 shell, providing an installation position for the brake disc 300. In this embodiment, the fixing post 710 is a solid plastic cylinder, and the brake disc 300 is rotatably mounted on the fixing post 710 through its positioning hole 370, thereby achieving rotatable installation positioning.

[0085] Figure 4 A structural diagram of the brake disc 300 is shown below. (The following is in conjunction with...) Figure 4 For a detailed introduction to the brake disc 300, please refer to [link / reference]. Figure 1 , Figure 2 .

[0086] As previously described, the brake disc 300 includes: a brake disc body 310; a support portion 330; an elongated hole 350; and a positioning hole 370.

[0087] The brake disc 300 is disposed on at least one side of the first traction disc 115, such as the first side, and on at least one side of the second traction disc 135 relative to the first traction disc 115, such as the second side. The brake disc 300 is generally "L-shaped", including a wedge-shaped brake disc body 310 and a support portion 330 extending from the brake disc body 310. The wedge-shaped brake disc body 310 is convenient to fit against the first side of the first traction disc 115 and the second side of the second traction disc 135, which are disposed opposite to each other. An elastic body 170 is provided on the contact surface of the brake disc 300 with the first side of the first traction disc 115 and the second side of the second traction disc 135. By adjusting the brake disc 300, the depth of the brake disc body 310 as a wedge-shaped body inserted into the gap can be adjusted, thereby making it fit against the first side of the first traction disc 115 and the second side of the second traction disc 135, and adjusting the tightness of the fit. This prevents the first traction disc 115 and the second traction disc 135 from rotating, thus braking the first rotating shaft 113 and the second rotating shaft 133. The brake disc 300 has an "L-shaped" wedge block with an extended support portion 330. A positioning hole 370 is provided at the end of the support portion 330 away from the main body. This positioning hole 370 is rotatably fitted onto the fixing post 710 of the locking device housing, allowing the brake disc 300 to swing about the fixed axis of the positioning hole 370. An elongated hole 350 is provided along the extending direction of the support portion 330 on the brake disc 300, allowing the cantilever column 519 to slide within the elongated hole 350. This embodiment selects the current technical solution; obviously, although this embodiment adopts the above technical solution, it does not exclude the use of other specific settings according to different operational requirements.

[0088] In this embodiment, optionally, the brake disc 300 is disposed on at least one side of the first side of the first traction disc 115. By adjusting the degree to which the brake disc body 310 abuts against the first side of the first traction disc 115, the fit between the brake disc body 310 and the first side of the first traction disc 115 will be tighter, thereby providing damping for the rotation of the first rotating shaft 113.

[0089] In this embodiment, optionally, the first side of the first traction disc 115 and the second side of the second traction disc 135 can be arranged opposite each other, with a set gap between them; the brake disc body 310 is a wedge-shaped block, and the depth of the wedge-shaped block of the brake disc body 310 inserted into the gap is adjusted. Due to the shape characteristics of the wedge-shaped block of the brake disc body 310, the brake disc body 310 achieves contact and compression with the elastic bodies 170 on both sides. As the insertion depth of the brake disc body 310 in the gap increases, the thickness of the brake disc body 310 at the contact position with the gap of the wedge-shaped block continuously increases, making it fit more tightly with the first side of the first traction disc 115 and the second side of the second traction disc 135, forming compression, thereby providing damping for the rotation of the first rotating shaft 113 and the second rotating shaft 133.

[0090] The above are merely some possible implementations of the brake disc 300. In practice, a wraparound brake disc 300 with multiple contact surfaces could also be considered, fitting against multiple sides of the first traction disc 115 and the second traction disc 135 to achieve the braking effect. Those skilled in the art can design based on the inspiration from the above-disclosed embodiments and in conjunction with their technical knowledge in the field.

[0091] Figure 5 A structural diagram of the drive member 510, which is a component of the brake disc drive assembly 500, is shown below. Figure 5 For a detailed description of the specific structure of the drive unit 510, please refer to [link / reference]. Figure 1 .

[0092] Figure 5 As shown, the driving component 510 includes: an outer edge platform 511; a hollow hole 513; a body 515; a cantilever 517; and a cantilever column 519.

[0093] The driving component body 515 is a hollow tube located at the lower end of the driving component 510. The driving component body 515 has a hollow driving component hole 513, through which it is fitted onto the outer diameter surface of the second rotating shaft 133. Symmetrical driving component outer edge platforms 511 are provided on the outer circumferential surface of the driving component body 515, which are fixed to the lower end of the lever 530. By moving the lever 530, the driving component 510 can be rotated. The front end of the driving component body 515 (… Figure 5 A cantilever 517 is fixed along the vertical direction on the left side, and the upper front end of the cantilever 517 ( Figure 5A cantilever column 519 is fixed on the upper left side. The cantilever column 519 is inserted into the elongated hole 350 on the brake disc 300. By driving the lever 530 to swing, the driving member 510 is rotated, thereby causing the cantilever column 519 to slide within the elongated hole 350.

[0094] When the endoscope is in operation, by moving the lever 530, the drive member 510 is driven to rotate synchronously. The cantilever column 519 on the drive member 510 then slides within the elongated hole 350. Driven by the cantilever column 519, the brake disc 300 swings around the positioning hole 370, thereby allowing the brake disc 300 to contact and compress with the elastic body 170. This adjusts the tightness of the fit with one side of the first traction disc 115 and one side of the second traction disc 135, thus providing the desired damping for the rotation of the first rotating shaft 113 and the second rotating shaft 133. Generally, the locking device 10 can have an unlocked state and a locked state, and can provide different degrees of damping in between.

[0095] The following are key references Figure 2 , Figure 3 The working process of the locking device 10 is described in detail.

[0096] Figure 2 It shows Figure 1 A schematic diagram of the locking device 10 in the unlocked state. Figure 3 It shows Figure 1 A schematic diagram of the locking device 10 in the locked state. Figure 2 , 3 All Figure 1 The diagram below shows the structure of the locking device 10 rotated counterclockwise, so that the second end of the locking device 10, i.e., the brake disc 300, faces out of the paper. (Refer to the following...) Figures 1 to 3 This section briefly describes the working process of the locking device 10, focusing on the operation process of switching between the locked and unlocked states.

[0097] When it is necessary to lock the endoscope locking device 10, the lever 530 is rotated clockwise along the handle 700 by a certain angle (e.g., ...). Figure 2(As shown from position A to position B), the lever 530 drives the drive member 510 to rotate around the second rotating shaft 133, and simultaneously drives the cantilever column 519 on the drive member 510 to slide within the elongated hole 350, causing the brake disc 300 to rotate clockwise around the positioning hole 370. This causes the brake disc 300 to contact and compress with the elastic body 170, achieving contact and compression with the first side of the first traction disc 115 and the second side of the second traction disc 135, thereby generating rotational resistance with the first rotating shaft 113 and the second rotating shaft 133. Furthermore, due to the... The brake disc body 310 is wedge-shaped, so that the deeper it penetrates into the gap between the first side of the first traction disc 115 and the second side of the second traction disc 135, the tighter its fit with these sides becomes. This continues until the first and second rotating shafts 113 and 133 cannot rotate due to resistance, and the first and second traction discs 115 and 135 are locked in their rotational positions by friction. At this point, the locking device enters a locked state, and the traction length of the traction wire associated with the traction discs in the vertical and horizontal directions within the endoscope guide tube is fixed, thus achieving endoscope lens angle locking. Please refer to... Figure 2 , Figure 3 The above process is Figure 2 Change to Figure 3 The process shows that the brake disc 300 is... Figure 2 When positioned, it did not contact the first side of the first traction disc 115. Figure 3 When in position, it contacts one side of the first traction disc 115; from this perspective, the second traction disc 135 is obscured, but its actual change is the same.

[0098] When it is necessary to unlock the endoscope locking device 10, the lever 530 is rotated counterclockwise along the handle 700 by a certain angle (e.g., ...). Figure 3(As shown from position B to position A), the lever 530 drives the drive member 510 to rotate around the second rotating shaft 133, and simultaneously drives the cantilever column 519 on the drive member 510 to slide within the elongated hole 350, causing the brake disc 300 to rotate counterclockwise around the positioning hole 370, thereby causing the brake disc 300 to separate from the elastic body 170, realizing separation from the first side of the first traction disc 115 and the second side of the second traction disc 135, thus eliminating friction with the first traction disc 115 and the second traction disc 135. The friction loaded on the first traction disc 115 and the second traction disc 135 gradually decreases until it disappears (the friction disappears after the brake disc 300 separates from the first side of the first traction disc 115 and the second side of the second traction disc 135). In this way, the locking device disengages from the above-mentioned locked state and enters the above-mentioned unlocked state. At this time, the first traction disc 115 and the second traction disc 135 can rotate flexibly according to the operator's operation of the first rotating wheel 111 and the second rotating wheel 131; the traction wire associated with the traction discs can be flexibly wound and unwound under the traction of the traction discs, thereby allowing the angle of the endoscope lens to be flexibly adjusted. Please refer to... Figure 2 , Figure 3 The above process is from Figure 3 Change to Figure 2 The process shows that the brake disc 300 is... Figure 3 When positioned, it contacts one side of the first traction disc 115. Figure 2 When in position, it does not contact the first side of the first traction disc 115; from this perspective, the second traction disc 135 is obscured, but its actual change is the same.

[0099] Between the locked and unlocked positions, the lever 530 can be operated to be positioned between A and B, placing the locking device in different damping states. This allows for varying degrees of adjustment of the rotating wheel's tightness as needed. This locking device enables the endoscope to be set to an appropriate state during adjustment. When unlocked, the endoscope lens angle can be freely adjusted via the rotating wheel; when locked, the endoscope is fixed, and the lens angle remains unchanged. The damping state, between these two, provides the operator with the desired feel for turning the rotating wheel, facilitating operation.

[0100] In the above embodiments, in principle, the combination of the lever 530 and the drive member 510 forms a lever mechanism. Since the lever 530 is relatively long, equivalent to the long arm of a lever, the drive member 510 can be easily moved to drive the brake disc 300 to swing via its cantilever column 519. Conversely, the swinging of the brake disc 300 is difficult to drive the lever 530. Furthermore, the cantilever column 519 fits tightly with the elongated hole 350 of the brake disc 300, creating a certain friction between them. The lever 530 also provides a load to hinder its movement. Therefore, it is difficult for the brake disc 300 to move due to loosening. In other words, the above locking device has good locking characteristics. When the lever 530 is moved to any position, it can be suspended there without external force and will not easily loosen.

[0101] The first embodiment described above is a preferred embodiment, and obviously, other variations are possible based on its fundamental principle. For example, the rotary assembly 100 includes a first rotary 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 rotary wheel 111 and the second rotary wheel 131, as mentioned earlier, are in opposite positions, rather than being at the same end as in this embodiment.

[0102] In the above embodiments, a further preferred embodiment is that the locking device for endoscope adjustment can further divide the brake disc and brake disc drive assembly into two groups, providing the damping for the first rotating shaft and the second rotating shaft respectively, thereby enabling independent control and adjustment of the endoscope's observation angles in the first and second dimensions. The second dimension and the first dimension are located in different directional dimensions.

[0103] Among them, the brake disc 300 can be configured according to Figure 1 The brake disc is divided into two parts, one brake disc and the other brake disc, from top to bottom along the 150mm center line. (See reference) Figure 1 The locking device structure, the position and structure of the brake disc drive assembly are comparable. Figure 1 Brake disc drive assembly 500 ( Figure 1 (Right side), Brake disc drive assembly two can be located on the other side of brake disc drive assembly one. Figure 1(Left side); One brake disc is disposed on one side of the first traction disc, and the other brake disc is disposed on one side of the second traction disc; Brake disc drive assembly one can adjust the tightness of the contact between the brake disc and the first side of the first traction disc, thereby providing the desired damping to the first rotating shaft; 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. Brake disc drive assembly two can adjust the tightness of the contact between the brake disc and the second side of the second traction disc, thereby providing the desired damping to the second rotating shaft; the rotation of the second traction disc is used to adjust the second traction wire, thereby adjusting the observation angle of the endoscope in the second dimension.

[0104] The preferred embodiments described above enable the endoscope to independently adjust the observation angle in another dimension while ensuring that the observation angle in one dimension is determined.

[0105] The second embodiment of this application provides an endoscope, as shown in the attached drawing. Figure 7 Specifically, in conjunction with the appendix Figure 1 - Appendix Figure 6 The structure and working process are described. Components with the same function as those in the first embodiment described above are given the same names as much as possible for ease of understanding. It should be noted that although the first and second embodiments share common innovative points, they still have significant differences. Therefore, the description of this embodiment should follow the naming provided in this embodiment and should not be forcibly matched with the first embodiment.

The rear end of the endoscope is the end that the operator holds during the actual surgery. Figure 7 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 10 is in the unlocked state. In the following description, it will be... Figure 7 The left side is called the rear. Figure 7 The right side is referred to as the front.

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 7 (Left side), the flexible part 80 and the lens 70 are located at the front end of the endoscope 2 ( Figure 7 (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 7 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 10 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 700 is controlled by the surgeon, who can externally operate the locking device 10 using a lever 530, thereby enabling observation of the lesion site inside the patient's body from different angles.

[0110] The endoscope structure 2 can bend the flexible traction wire 30 at any angle via the locking device 10. The locking device 10 adjusts the extension length of the traction wire 30 in the first traction disc 115, thereby adjusting the angle of the lens 70 at a fixed position. For a detailed explanation of the process of adjusting the locking and unlocking states of the locking device 10 using the lever 530, please refer to Embodiment 1; further details are omitted here.

[0111] Figure 7 front end ( Figure 7 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.
