Description

Technical Field

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

[0002] With the development of modern 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 fixed at a certain angle. To facilitate observation of lesions, a locking mechanism is installed on the endoscope. The movement of the flexible part is controlled by the locking device at the rear of the endoscope, 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 devices. The present invention also provides a locking device.

[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, a support member, and a body; The first rotating wheel is connected to the first end of the first rotating shaft, and the second end of the first rotating shaft is provided with a first traction disc; the support member is disposed in the body of the locking device, the main body of the support member is a support frame, and the first rotating shaft is supported by the support frame; by the swing of the support frame, the first rotating shaft is driven to swing, and the first rotating shaft is subjected to different degrees of compression by a specially designed force structure due to being in different swing positions, thereby giving the first rotating shaft different degrees of clamping force, so that the rotation of the first rotating shaft obtains the required damping; the rotation of the first rotating shaft is used to adjust the first traction disc, and the first traction wire is adjusted through the first traction disc, thereby adjusting the observation angle of the endoscope in the first dimension.

[0007] In one embodiment of this application, the locking device further includes a support drive member, which provides a control position for the swinging of the support member. The support member has a positioning shaft intersecting the axis of the first rotating shaft. The support drive member can control the swinging of the support frame around the positioning shaft. The force structure specifically includes: different degrees of interference between the support frame and the body when the support frame swings to different positions, and the support frame having elastic deformation characteristics. The interference relationship causes the support frame to be compressed to different degrees at different swinging positions, and the support frame undergoes elastic deformation. Thus, the first rotating shaft obtains different degrees of clamping force through the support frame.

[0008] In one embodiment of this application, the support frame is C-shaped in cross-section perpendicular to the first axis of rotation, and the opening of the C-shape provides elastic deformation space for the support frame.

[0009] In one embodiment of this application, the joint of the C-shaped cross section is provided with a gap to increase the space for elastic deformation.

[0010] In one embodiment of this application, a radially extending protrusion is provided on the support frame, and the end of the protrusion is engaged with the support drive member to transmit the force provided by the support drive member to the support frame.

[0011] In one embodiment of this application, the support drive includes a slider. The operating part of the slider is disposed on the outer surface of the body. The portion of the slider located inside the body includes a wedge-shaped surface that engages with the protrusion of the support frame. The slider is slidable along a slider guide rail disposed on the body. During the sliding process, a force that causes the support to rotate is transmitted to the support through the wedge-shaped surface and the protrusion of the support frame.

[0012] In one embodiment of this application, the positioning shaft includes a first end and a second end symmetrically arranged on both sides of the support frame, the axis provided by which is perpendicular to the first rotating shaft, and the ends of the first end and the second end are rotatably pivotally connected to the support position provided in the body.

[0013] In one embodiment of this application, the support frame swings to different positions and forms different degrees of interference with the body. The interference is achieved by an interference surface disposed on the body and located within the body. The interference surface is disposed at a position near the first end of the positioning shaft. When the support member rotates to a set angle, the interference surface provides a compressive force to the support frame through a compressive surface located on one side of the support frame, thereby compressing the support frame. By setting the shape and position of the interference surface, the support frame swings to different positions and forms different degrees of interference with the interference surface.

[0014] In one embodiment of this application, a limiting surface is provided at the position where the body and the second end of the positioning shaft are joined, and the side of the support frame near the second end of the positioning shaft has an abutment surface that cooperates with the extrusion force.

[0015] In one embodiment of this application, the locking device further includes: a second rotating wheel and a second rotating shaft; the second rotating wheel is connected to the first end of the second rotating shaft, and the first rotating shaft and the second rotating shaft are coaxial, with the second rotating shaft sleeved on the outer circumferential surface of the first rotating shaft; a second traction disc is provided at the second end of the second rotating shaft; the second rotating shaft is also supported by the support frame, and when the support frame is swung, the second rotating shaft and the second traction disc sway accordingly; while the first rotating shaft obtains different degrees of clamping force, the second rotating shaft also obtains different degrees of clamping force through the support frame, so that the rotation of the second rotating shaft obtains the required damping; the rotation of the second rotating shaft is used to adjust the second traction disc, and the second traction wire is adjusted through the second traction disc, thereby adjusting the observation angle of the endoscope in the second dimension, which is in a different directional dimension from the first dimension.

[0016] In one embodiment of this application, the support frame includes a first support frame and a second support frame, wherein the first support frame is used to provide different degrees of clamping force to the first rotating shaft; and the second support frame is used to provide different degrees of clamping force to the second rotating shaft.

[0017] In one embodiment of this application, the second end of the first rotating shaft is fitted with and supported by the first brake hole provided on the body. The size of the first brake hole allows the first rotating shaft to have a swinging space therein. The specially provided force structure is specifically the aperture of the first brake hole that varies in the swinging direction. This varying aperture causes the first rotating shaft to be compressed to different degrees at different swinging positions located in the first brake hole.

[0018] In one embodiment of this application, the first brake hole is specifically an elastic locking hole obtained by cutting the machine body housing. When the second end of the first rotating shaft enters the elastic locking hole, the elastic locking hole will be opened, and the reaction force of the elastic locking hole will cause the first rotating shaft to be squeezed.

[0019] In one embodiment of this application, the first brake hole further includes an expansion joint disposed on the housing, the expansion joint being located at the end of the elastic locking hole.

[0020] In one embodiment of this application, the support member further has a positioning shaft that intersects perpendicularly with the axis of the first rotating shaft. The positioning shaft is disposed at both ends of the support frame and is rotatably connected to the body.

[0021] In one embodiment of this application, the support frame is C-shaped in general, and the C-shaped support frame is disposed in the body of the machine.

[0022] In one embodiment of this application, the locking device further includes: a second rotating wheel and a second rotating shaft; the second rotating wheel is connected to the first end of the second rotating shaft; a second traction disc is disposed near the second end of the second rotating shaft; the second rotating shaft is disposed on the outer circumferential surface of the first rotating shaft, and a second braking hole is provided at the junction of the first end of the second rotating shaft and the machine body on the machine body; the first rotating shaft and the second rotating shaft pass through the machine body housing through the second braking hole on the machine body; the second braking hole and the first braking hole together provide support for the first rotating shaft and the second rotating shaft; the support frame of the support member simultaneously provides floating support for the second rotating shaft and the second traction disc; while the first rotating shaft swings, the second rotating shaft swings with the first rotating shaft; the second braking hole has a diameter that varies in the swing direction, and this varying diameter causes the second rotating shaft to be compressed to different degrees at different swing positions located at the second braking hole; 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, which is in a different directional dimension from the first dimension.

[0023] This application embodiment also provides a locking device, including: a first rotating wheel, a first rotating shaft, a support member, and a body; the first rotating wheel is connected to a first end of the first rotating shaft, and a first functional disk is provided at the second end of the first rotating shaft; the support member is disposed in the body of the locking device, the main body of the support member being a support frame, and the first rotating shaft is supported by the support frame; by swinging the support frame, the first rotating shaft is driven to swing, and the first rotating shaft is subjected to different degrees of compression by a specially designed force structure due to being in different swinging positions, thereby giving the first rotating shaft different degrees of clamping force, and giving the rotation of the first rotating shaft the required damping; the rotation of the first rotating shaft is used to rotate the first functional disk, and the required adjustment function is achieved by rotating the first functional disk.

[0024] The locking device for endoscope adjustment provided in this application includes a first rotating wheel, a first rotating shaft, a support member, and a body. The first rotating wheel is connected to the first end of the first rotating shaft, and a first traction disc is provided at the second end of the first rotating shaft. The support member is located inside the locking device, and the main body of the support member is a support frame, which supports the first rotating shaft. By swinging the support frame, the first rotating shaft is driven to swing, and the first rotating shaft is subjected to different degrees of compression by a specially designed force structure due to its different swing positions. This results in the first rotating shaft obtaining different degrees of clamping force, and the rotation of the first rotating shaft obtaining the required damping. Thus, when the locking device is working, the curved part of the distal end of the endoscope can be bent and fixed at any angle, ultimately achieving angular flexibility and stability of the endoscope lens during endoscope operation, and improving the efficiency of the surgery.

[0025] In one preferred embodiment of this application, the locking device further includes a support drive member, which provides a control position for the swinging of the support member. The support member has a positioning shaft intersecting the axis of the first rotating shaft. The support drive member can control the swinging of the support frame around the positioning shaft. The force-bearing structure specifically includes: different degrees of interference between the support frame and the machine body when the support frame swings to different positions; and the support frame having elastic deformation characteristics. The interference causes the support frame to be subjected to different degrees of compression at different swinging positions, resulting in elastic deformation of the support frame. This, in turn, allows the first rotating shaft to obtain different degrees of clamping force through the support frame. This preferred embodiment features a simple structure, convenient one-handed operation for the user, and continuous adjustment of the compressive force borne by the support frame.

[0026] In a second preferred embodiment of this application, the second end of the first rotating shaft is fitted into and supported by a first brake hole provided on the body. The size of the first brake hole allows the first rotating shaft to have room to swing within it. The force structure specially provided in this embodiment is specifically the aperture of the first brake hole that varies in the swing direction. This varying aperture causes the first rotating shaft to be compressed to different degrees at different swing positions located in the first brake hole. The second end of the first rotating shaft bears different radial pressures at different support positions in the brake hole, thereby providing corresponding damping for the rotation of the first rotating shaft. The locking device in this preferred embodiment has the characteristics of high flexibility and good adjustability in switching between locked and unlocked states. Attached Figure Description

[0034] In existing endoscopes, locking handwheels are typically used to adjust the endoscope lens. However, this process suffers from several problems, including insufficient stability, low positioning accuracy, and inflexible bending angles when operating the lens.

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.

[0037] The basic scheme of this application described above will be further explained below through two possible specific implementation schemes. The core difference between the two specific implementation schemes lies in the different implementation methods used for the force structure. The first specific implementation scheme includes the first embodiment and the second embodiment; the second specific implementation scheme includes the third embodiment and the fourth embodiment.

[0038] The following is in conjunction with the appendix Figure 1 - Appendix Figure 14 The first embodiment of this application is described in detail below. The advantages of this embodiment are its simple structure, ease of one-handed operation by the user, and ability to continuously adjust the compressive force borne by the support frame.

[0039] like Figure 1 The diagram shown is a cross-sectional view of the locking device 10 for endoscope adjustment provided in this embodiment; wherein, Figure 1 The left side is the first end of the locking device 10, that is, one end of the rotating wheel assembly 100; Figure 1 The right side shows the second end of the locking device 10; the view in this figure does not show the support drive member 500, so please refer to [the image]. Figure 2 The indication, Figure 2 for Figure 1 The diagram shows the structure of the locking device 10 rotating counterclockwise, causing some components of the support drive member 500 to face out of the paper.

[0040] like Figure 1 , Figure 2 As shown, the locking device 10 includes the following components or parts: a rotating wheel assembly 100; a support member 300; a support drive member 500; and a body 700.

[0041] The arrangement of the above-mentioned components can be roughly described as follows: the rotating wheel assembly 100 is located at the first end of the locking device 10 ( Figure 1 (Left side), the support member 300 is located in the middle position of the locking device 10 ( Figure 1 In the middle), the rotating wheel assembly 100 is supported within the elastically deformable support frame of the support member 300, which is disposed within the housing of the body 700 and can achieve fixed-axis rotation; the body 700 provides an assembly base for other components of the locking device 10, and the rotating wheel assembly 100, the support member 300, and the support drive member 500 are assembled onto the housing of the body 700, wherein the drive body 510 (sliding button 510) of the support drive member 500 is disposed on the outer surface of the housing of the body 700 (see reference). Figure 2 (Illustrative diagram) Some components of the support drive 500 are combined with the support frame of the support 300, so that the user can apply a corresponding force to the support frame through the support drive 500 via the slide button 510, so that the locking device 10 can be locked and released. The specific structure and working process will be described later.

[0042] The force provided by the support drive member 500 can control the support member 300 to rotate on a fixed axis within the housing of the body 700. The rotating wheel assembly 100 rotates accordingly. When the support frame of the support member 300 swings to different positions within the body 700, different degrees of interference are formed between the outer surfaces on both sides of the support frame and the inner surface of the body 700. Consequently, the support frame of the support member 300 is compressed by the housing of the body 700. Since the support frame of the support member 300 itself has elastic deformation characteristics, it can provide different degrees of clamping force to the rotating wheel assembly 100, so that the rotation of the rotating wheel assembly 100 obtains the required damping, thereby achieving the locking or unlocking of the locking device 10.

[0043] In this embodiment, the force-bearing structure specifically refers to the different degrees of interference between the support frame of the support member 300 and the body 700 when the support frame swings to different positions, and the elastic deformation characteristics of the support frame. This interference causes the support frame to be compressed to different degrees at different swing positions, resulting in elastic deformation of the support frame. Since this force-bearing structure serves as a functional limitation for the interference relationship and elastic deformation characteristics, no corresponding component is provided in the locking device.

[0044] The following sections will describe in detail the rotary wheel assembly 100, the support component 300, the support drive component 500, and the body 700.

[0045] The rotary wheel assembly 100 includes: a first rotary wheel assembly 110; and a second rotary wheel assembly 130.

[0046] The following details each component. Please refer to the provided text for easier understanding. Figure 3 , Figure 4 The illustration; Figure 3 for Figure 1 A partially enlarged structural diagram of the locking device 10 (for ease of observation). Figure 3 (This is a diagram showing the hidden 700-unit configuration). Figure 4 To and Figure 3 Corresponding cross-sectional structural diagram.

[0047] The wheel assembly 100 includes a first wheel assembly 110 and a second wheel assembly 130. The first wheel assembly 110 includes a first wheel 111, a first shaft 113, and a first traction disc 115; the second wheel assembly 130 includes a second wheel 131, a second shaft 133, and a second traction disc 135.

[0048] like Figure 3 , Figure 4 As shown, in this embodiment, 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; the first traction disc 115 is mounted at the other end of the first rotating shaft 113, i.e., the second end of the first rotating shaft 113. Figure 3 (Right 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 3(Right side) Position. In addition, the first rotating wheel 111 is located closer to the first end of 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 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 will be significantly different from that of this embodiment, but the principle is not fundamentally different.

[0049] To facilitate understanding, the structure of the first traction disc 115 in the wheel assembly 100 will be described in detail below.

[0050] 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.

[0051] Please refer to Figure 5 The indication, Figure 5 for Figure 1 A schematic diagram of the structure of the first traction disc 115 of the locking device 10 is shown in the figure; the figure also shows the first rotating shaft 113 connected to the first traction disc 115.

[0052] The following combination Figure 5 For a detailed description of the specific structure of the first traction disc 115, please refer to [reference needed]. Figure 1 , Figure 3 , Figure 4 .

[0053] Please see Figure 5 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 first dimension controlled by the first traction wire 1153.

[0054] In this embodiment, 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 bidirectional 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 for fitting and fixing with the first rotating shaft 113. The first traction disc 115 is installed at the second end of the first rotating shaft 113 through this structure.

[0055] 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, and the observation angle in the first dimension is specifically 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 described above are only an illustration, and other possible compositions and control methods for the traction wire are not excluded.

[0056] Similar to the first traction disc, the second traction disc 135 has a similar structure, the difference being that it is positioned near the second end of the second rotating shaft 133. This second traction disc 135 is used to fix the second traction wire, and the composition of the second traction wire is similar to that of the first 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, 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 in the second dimension, thereby adjusting its extension distance.

[0057] In the locking device 10 of this application, each of the above-mentioned traction wires is embedded in the endoscope's conduit. The two ends of the traction wire are respectively positioned at the curved end of the endoscope conduit and the traction disc end. One end is connected to the traction disc, and the other end is fixed in the conduit. 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 conduit, the traction wire drives the rotation of the flexible part at the distal end of the conduit, thereby causing the endoscope lens to rotate in a certain dimension (up and down, or left and right), so that the endoscope lens can deflect at a certain angle and change the observation angle.

[0058] The following describes the support component 300, the support drive component 500, and the body 700; since the three are closely related, there is some overlap in the content of the description.

[0059] The support member 300 includes: a support member body 310; and a positioning shaft 330.

[0060] Figure 6 This is a schematic diagram of the structure of the support member 300 in the locking device 10; Figure 7 for Figure 6 A structural schematic diagram of the support member 300 from another perspective; Figure 8for Figure 7 The following is a top view diagram of the supporting components; for reference only. Figure 6 , Figure 7 , Figure 8 The illustrations are provided for reference. Figure 1 .

[0061] The support body 310 is an integral support frame, which can undergo corresponding elastic deformation when subjected to compressive force; the first rotating shaft 113 and the second rotating shaft 133 are supported by the support frame of the support body 310; in this embodiment, as a specific implementation, the support body 310 surrounds the outer peripheral surfaces of the first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135. Figure 1 (Middle to right), so that the first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135 as a whole can swing with the swing of the support frame of the support body 310; when the support frame of the support body 310 swings to different positions, different degrees of interference are formed between the outer surfaces of the two sides of the support frame and the inner surface of the body 700, so that the support frame of the support body 310 is subjected to different compressive forces at different swing positions. Furthermore, through the elastic force generated by the elastic deformation of the support frame, different degrees of clamping force are provided to the first rotating shaft 113 and the second rotating shaft 133, so that the rotation of the first rotating shaft 113 and the second rotating shaft 133 obtains the required damping. It should be noted that the clamping force on the first rotating shaft 113 and the second rotating shaft 133, in this embodiment, also acts on the first traction disc 115 and the second traction disc 135, jointly achieving a damping effect. In other embodiments, it may act directly on the first traction disc 115 and the second traction disc 135; or it may act directly on the first traction disc 115 and the second rotating shaft 133, or directly on the second traction disc 135 and the first rotating shaft 113. In short, the above two sets of action positions—the first set: the first rotating shaft 113 and the first traction disc 115, and the second set: the second rotating shaft 133 and the second traction disc 135—can be arbitrarily paired. However, even if it acts on the first traction disc 115 or the second traction disc 135, the clamping force ultimately acts on the rotating shaft through the aforementioned traction discs. Therefore, providing clamping force on the first rotating shaft 113 and the second traction disc 133 is used here as a unified way to describe the above various situations.

[0062] The positioning shaft 330 is symmetrically arranged on the outer surface of the support frame of the support body 310 and embedded in the inner surface of the body 700, intersecting with the axis of the first rotating shaft 113; the positioning shaft 330 provides a movable basis for the fixed-axis rotation of the support frame of the support body 310 within the body 700.

[0063] The following details the support body 310 and the positioning shaft 330.

[0064] The support body 310 includes: a compression surface 311; a protrusion 312; a strip slit 313; abutment surface 314; a first support frame 315; a second support frame 316; and an opening 317.

[0065] The positioning shaft 330 includes: a first end 331 of the positioning shaft; and a second end 333 of the positioning shaft.

[0066] Figure 6 This is a schematic diagram of the support member 300 in the locking device 10. Due to the viewing angle, not all components of the support member body 310 are shown in this figure; Figure 6 As shown, the support frame of the support body 310 is composed of a first support frame 315 and a second support frame 316. In this embodiment, the first support frame 315 is disposed on the outer peripheral surface of the first rotating shaft 113 and the first traction disc 115, supporting the first rotating shaft 113 and the first traction disc 115; the second support frame 316 is disposed on the outer peripheral surface of the second rotating shaft 133 and the second traction disc 135, supporting the second rotating shaft 133 and the second traction disc 135; the first support frame 315 and the second support frame 316 are C-shaped in cross-section perpendicular to the first rotating shaft 113 (see reference). Figure 7 (Illustration in the diagram) The opening 317 of the C-shaped support frame provides space for elastic deformation of the support frame. At the opposite end of the opening 317 on the C-shaped support frame, at the junction of the first support frame 315 and the second support frame 316, a strip-shaped slot 313 is provided to increase the elastic deformation characteristics. The strip-shaped slot 313 and the opening 317 provide deformation space for the elastic deformation of the support frame structure of the support body 310. A protruding protrusion 312 is also provided on the support frame of the support body 310. The distal end of the protrusion 312 is combined with the support drive member 500 to receive the force provided by the support drive member 500 to the support frame. One side of the support frame is provided with a compression surface 311 that contacts the inner surface of the body 700 (see reference). Figure 8(Illustration of the diagram), and an abutment surface 314 disposed on the other side, wherein the compression surface 311 is used to press the compression surface 311 on one side of the inner surface of the body 700 against the compression surface 311 on the other side of the support frame when the support frame is rotated to a set angle, thereby subjecting the support frame to a compressive force; the abutment surface 314 is used to cooperate with the rotation of the support frame so that the compressive force generated when it is rotated to a set angle can fully act on the support frame and deform it due to being abutted at the opposite end of the force-bearing surface.

[0067] The positioning shaft 330 consists of a first positioning shaft 331 and a second positioning shaft 333 symmetrically arranged on both sides of the support frame. The axis it provides is perpendicular to the first rotating shaft 113. The ends of the first positioning shaft 331 and the second positioning shaft 333 are both pivotally connected to the body 700 in a rotatable manner.

[0068] After introducing the structure of the support component 300, the main body 700 will be introduced next for easier understanding.

[0069] The body 700 is named after its function as a handle of the endoscope. It is called a handle because it serves as a handle in the overall structure of the endoscope. In this application, it is equivalent to a body that provides a positioning base. The body 700 is generally designed as two interlocking covers that can be disassembled according to assembly and repair needs. The body 700 is also used to form different degrees of interference with the support body 310.

[0070] The body 700 includes: a support position 710; a sliding guide rail 730; an interference surface 750; a limiting surface 770; and a rotating shaft through hole 790.

[0071] The support position 710 includes: a first support position 711; and a second support position 713.

[0072] Figure 9 for Figure 1 A schematic diagram of the internal structure of one side of the locking device of the machine body 700. Figure 10 for Figure 9 A schematic diagram of the internal structure of the organism from another perspective; in which... Figure 9 This is a schematic diagram viewed from the bottom of the endoscope. Figure 10 This is a schematic diagram showing the view from the top (spherical handle) of the endoscope body; Figure 11 for Figure 1 A schematic diagram of the external structure of the body 700 in the locking device; see below for reference. Figure 9 , Figure 10 , Figure 11 The illustrations are provided for reference. Figure 1 .

[0073] like Figure 9 As shown, the body 700 is a hollow cylindrical shell, the interior of which provides movable space for the support frame of the support body 310. The inner surface of the body is provided with support positions 710, interference surfaces 750, and limiting surfaces 770; the support position 710 consists of a first support position 711 ( Figure 9 Above), second support level 713 ( Figure 9 The first support position 711 and the second support position 713 are arranged opposite to each other on the inner surface of the hollow circular shell of the body 700, and are used to provide a positioning basis for the first frame 315 and the second support frame 316 in the support member 300; the interference surface 750 is located near the first end 331 of the positioning shaft, and the limiting surface 770 is located at the position where it engages with the second end 333 of the positioning shaft. Figure 10 (below); through the interference surface 750 and the limiting surface 770, when the support member 300 rotates to a set angle, the interference surface 750 presses the compression surface 311 located on one side of the support frame, and the limiting surface 770 provides abutment surface to the other side of the support frame, thereby cooperating with the interference surface 750 to make the support frame of the support member 300 subject to compression force, and when the support frame rotates to any angle, it can self-lock with the body 700. Without external force intervention, the support frame will not slip with the body 700 due to its own elasticity.

[0074] The interference surface 750 has a gradually changing irregular shape, so that the degree of interference between it and the compression surface 311 of the support frame of the support body 310 changes with the rotation angle, thereby allowing the support frame to withstand different compression forces at different rotation angles.

[0075] like Figure 9 , Figure 11 As shown, the body 700 also includes a sliding guide rail 730 obtained by cutting the housing of the body 700 on the surface of the body 700. Figure 11 (middle) and the shaft through hole 790 ( Figure 9 (middle); wherein, the slide rail 730 is used to define the movement path of the drive body 510 (slide) in the support drive 500, and the pivot through hole 790 is used to provide a foundation for the first pivot 113 and the second pivot 133 to pass through one side of the body 700 and float within the housing of the body 700.

[0076] The following section will detail the support drive component 500.

[0077] Figure 12 This is a structural schematic diagram of the support drive component 500 in the locking device 10. Figure 13 for Figure 12A schematic diagram of the supporting drive component from another perspective; wherein, Figure 12 To and Figure 2 The left view corresponding to the support drive component 500 in the middle; Figure 13 To and Figure 12 The corresponding left view; combined with the following Figure 12 and Figure 13 A detailed introduction to the support drive component 500 is provided.

[0078] The support drive component 500 includes: a drive component body 510; and a wedge-shaped surface 511.

[0079] The drive body 510 is a slider. The operating part of the slider is located on the outer surface of the body 700. The part of the slider located inside the body 700 includes a wedge-shaped surface 511 that engages with the protrusion 312 of the support frame. The slider can slide along the slider guide rail 730 provided on the body 700. During the sliding process, the deformation of the wedge-shaped surface 511 and the force provided to the support member 300 through the protrusion 312 of the support frame cause the support member 300 to rotate.

[0080] Having introduced the various components of the locking device 10, the working process of the locking device 10 will now be described.

[0081] When the endoscope is in operation, by sliding the slider of the drive body 510, the force exerted on the slider, through the engagement of the wedge-shaped surface 511 on the drive body 510 and the protrusion 312 on the support body 310, controls the support frame of the support body 310 to rotate around the axis provided by the positioning shaft 330. The first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135 move together with the support frame. When the support frame of the support body 310 swings to different positions, different degrees of interference are formed between the compression surface 311 on the support frame and the interference surface on the inner surface of the body 700. The abutment surface 314 on the support frame and the limiting surface 770 on the inner surface of the body ensure the stability of the above interference relationship. The presence of this force causes the aforementioned support frame to be compressed. Because the support frame has strip-shaped slots 313 and openings 317, it possesses elastic deformation characteristics. Under the combined action of the compression force and the elastic deformation characteristics of the support frame, the support frame provides varying degrees of clamping force to the first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135 as a whole. This provides the necessary damping for the rotation of the first rotating shaft 113 and the second rotating shaft 133. The rotation of the first rotating shaft 113 is used to adjust the first traction wire 1153, thereby adjusting the endoscope's observation angle in the first dimension. The rotation of the second rotating shaft 133 is used to adjust the second traction wire, thereby adjusting the endoscope's observation angle in the second dimension, which is a different directional dimension from the first dimension. Generally, the locking device 10 can have an unlocked state and a locked state, and can provide different degrees of damping in between.

[0082] The following are key references Figure 14 The working process of the locking device 10 is described in detail. Figure 14 It shows Figure 1 A schematic diagram of the locking device 10 in the unlocked state.

[0083] Figure 14 The diagram below shows the structure of the locking device 10 with the second end, i.e., the support member 300, facing out of the plane of the paper. (Refer to the following...) Figure 14 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.

[0084] When it is necessary to lock the endoscope locking device 10, the slider is moved counterclockwise along the endoscope body 700 by a certain angle (e.g., Figure 14(As shown from position A to position B), the force provided by the drive body 510, under the deformation of the wedge-shaped surface 511 at this angle, causes the support frame of the support body 310 to rotate around the axis provided by the positioning shaft 330 until it reaches its maximum rotational limit. During this process, the contact area between the compression surface 311 on the support frame and the interference surface on the inner surface of the body 700 increases. Furthermore, due to the irregular design of the size and position of the interference surface 750, the compression of the interference surface 750 on the support frame continuously increases, ultimately forming a maximum interference relationship, so that the support frame is subjected to the maximum compressive force when it rotates to the maximum angle; at the same time, the abutment surface 314 on the support frame and the inner surface of the body... Stable contact is maintained between the limiting surfaces 770, ensuring the stable existence of the aforementioned compressive force. Under this maximum compressive force, the support frame itself, due to its elasticity, undergoes maximum compressive deformation of the strip 313 and opening 317 on its frame. This provides maximum clamping force to the first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135 as a whole, preventing the first rotating shaft 113 and the second rotating shaft 133 from rotating. The first traction disc 115 and the second traction disc 135 are locked in their rotational positions by this clamping force, and the locking device 10 enters the locked state. The traction length of the traction wires associated with the aforementioned traction discs in the vertical and horizontal directions within the endoscope guide tube is fixed, thus achieving endoscope lens angle locking. Of course, if complete clamping is not required, the required clamping force can be obtained by sliding the drive body 510 to a suitable position between A and B, and the first rotating shaft 113 and the second rotating shaft 133 will correspondingly obtain appropriate damping.

[0085] When it is necessary to unlock the endoscope locking device 10, the slider is moved clockwise along the endoscope body 700 by a certain angle (e.g., ...). Figure 14(As shown from position B to position A), the force provided by the drive body 510 causes the support frame of the support body 310 to rotate around the axis provided by the positioning shaft 330. As a result, the contact area between the compression surface 311 on the support frame and the interference surface of the inner surface of the body 700 gradually decreases until there is no contact area, thus eliminating the interference relationship and minimizing the compression force on the support frame. Due to the elasticity of the support frame itself, the compression deformation generated by the strip slit 313 and the opening 317 on the frame gradually decreases until it disappears. As a result, the clamping force on the first rotating shaft 113, the first traction disc 115, the second rotating shaft 133, and the second traction disc 135 gradually decreases until it disappears. The locking device 10 enters the above-mentioned unlocked state. The first traction disc 115 and the second traction disc 135 can rotate flexibly with the operator's operation of the first rotating wheel 111 and the second rotating wheel 131. The traction wire associated with the 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.

[0086] 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.

[0087] Corresponding to the first embodiment described above, the second embodiment of this application 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 being limited to endoscopes.

[0088] The following combination Figures 1-14 The structure and working process are described. 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 first and second embodiments share common innovations, 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.

[0089] 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.

[0090] The locking device 10' includes: a first rotating wheel 111, a first rotating shaft 113, a support member 300, and a body 700; The first rotating wheel 111 is connected to the first end of the first rotating shaft 113, and the second end of the first rotating shaft 113 is provided with a first function disk 115'; The support member 300 is disposed inside the body 700 of the locking device 10'. The main body of the support member 300 is a support frame, and the first rotating shaft 113 is supported by the support frame. The swing of the support frame causes the first rotating shaft 113 to swing, and the first rotating shaft 113 is subjected to different degrees of compression by the specially designed force structure due to its different swing positions, thereby giving the first rotating shaft 113 different degrees of clamping force and giving the rotation of the first rotating shaft 113 the required damping. Optionally, the locking device 10' further includes a support drive member 500, which provides a control position for the swing of the support member 300. The support member 300 has a positioning shaft 330 intersecting the axis of the first rotating shaft 113. The support drive member 500 can control the swing of the support frame with the positioning shaft 330 as the rotation axis. The force structure specifically includes: different degrees of interference relationship formed between the support frame and the body 700 when the support frame swings to different positions, and the support frame has elastic deformation characteristics. The interference relationship causes the support frame to be compressed to different degrees at different swing positions, and the support frame undergoes elastic deformation, thereby enabling the first rotating shaft to obtain different degrees of clamping force through the support frame.

[0091] The locking device 10' provided in the second embodiment described above may also include other necessary structures, such as detection equipment, display equipment, etc., for cooperating with the locking device. It should be understood that the working process of the locking device in this embodiment is similar to that in Embodiment 1; please refer to Embodiment 1 for details. Further elaboration is not required in this embodiment.

[0092] The third embodiment of this application provides another locking device for endoscope adjustment. The advantage of this embodiment is that the locking device in this implementation has high flexibility in switching between locked and unlocked states and good adjustability.

[0093] The locking device for endoscope adjustment provided in the third embodiment of this application includes: a first rotating wheel, a first rotating shaft, a support member, and a body; the first rotating wheel is connected to a first end of the first rotating shaft, and a first traction disc is provided at the second end of the first rotating shaft; the second end of the first rotating shaft is fitted into the body through a first braking hole provided on the body and is supported, the size of the first braking hole allows the first rotating shaft to have a swinging space therein; the support member is provided in the body of the locking device, the main body of the support member is a support frame, and the first rotating shaft is supported by the support frame; by swinging the support frame, the first rotating shaft is driven to swing, and the first rotating shaft is subjected to different degrees of compression by a specially designed force structure due to being in different swinging positions. The specially designed force structure is specifically the aperture of the first braking hole that varies in the swinging direction. This varying aperture causes the first rotating shaft to be subjected to different degrees of compression at different swinging positions located in the first braking hole, thereby giving the first rotating shaft different degrees of clamping force, and the rotation of the first rotating shaft obtains the required damping; the rotation of the first rotating shaft is used to rotate the first traction disc, and the first traction wire is adjusted through the first traction disc, thereby adjusting the observation angle of the endoscope in the first dimension.

[0094] The following is in conjunction with the appendix Figure 15 -Appendix Figure 22 The third embodiment of this application is described in detail.

[0095] like Figure 15 The diagram shown is a cross-sectional view of the locking device 210 for endoscope adjustment provided in this embodiment; wherein, Figure 15 The left side is the first end of the locking device 210, that is, the end where the rotating wheel assembly 2100 is located. Figure 15 The right side is the second end of the locking device 210; the support member 2300 is located in the middle of the locking device 210. Figure 15 (In the middle), some components of the rotating wheel assembly 2100 are disposed within the frame structure of the support member 2300; the body 2500 provides a positioning basis for the rotating wheel assembly 2100 and the support member 2300. Figure 16 for Figure 15 The diagram shows the structure of the locking device 210 rotating clockwise so that the second end of the locking device 210, i.e. the end of the rotating wheel assembly 2100, faces outward from the paper. Figure 17 for Figure 15 The diagram shows the structure of the locking device 210 rotating counterclockwise so that the first end of the locking device 210, i.e. the first end of the rotating wheel assembly 2100, faces outward from the paper.

[0096] like Figure 15 As shown, the locking device 210 includes the following components or parts: a rotating wheel assembly 2100; a support member 2300; and a body 2500.

[0097] The arrangement of the above-mentioned components can be roughly described as follows: the rotating wheel assembly 2100 is located at the first end of the locking device 210 ( Figure 15 (Left side); the support member 2300 is located in the middle position of the locking device 210 ( Figure 15 The support member 2300 is a frame structure, located in the middle of the machine body 2500, and is used to float and support the rotating wheel assembly 2100. Specifically, some components of the rotating wheel assembly 2100 are floated within the support frame of the support member 2300, and the end (second end) of the first rotating shaft included in the rotating wheel assembly 2100 is fitted into the first brake hole of the machine body 2500. This first brake hole is a specially designed force-bearing structure. By operating the support member 2300, the support frame of the support member 2300 is rotated, thereby driving... The first shaft of the rotating wheel assembly 2100 within the support frame of the moving support member 2300 swings; through the swing of the first shaft of the rotating wheel assembly 2100, the position of the second end of the first shaft of the rotating wheel assembly 2100 in the first brake hole on the body 2500 changes. Since the first brake hole on the body 2500 has a varying aperture in the swing direction, it can subject the first shaft of the rotating wheel assembly 2100 to different degrees of compression at different swing positions in the first brake hole, thereby providing the desired damping for the rotation of the rotating wheel assembly 2100.

[0098] In this embodiment, the body 2500 is actually the handle of the locking device 210, which is used to provide a positioning base for the rotary wheel assembly 2100 and the support member 2300. It is called a handle because it is a handle in the overall structure of the endoscope. Its specific structure will be described later.

[0099] The following section introduces the 2100 rotary assembly. For easier understanding, please refer to [link / reference needed]. Figure 18 and Figure 19 The illustration; Figure 18 A partial structural diagram showing the locking device 210 hidden behind the body 2500; Figure 19 for Figure 18 The corresponding cross-sectional structural diagram.

[0100] The rotary wheel assembly 2100 includes: a first rotary wheel assembly 2110; and a second rotary wheel assembly 2130.

[0101] The following is a detailed introduction to each component.

[0102] The wheel assembly 2100 includes a first wheel assembly 2110 and a second wheel assembly 2130; the first wheel assembly 2110 includes a first wheel 2111, a first shaft 2113, and a first traction disc 2115; the second wheel assembly 2130 includes a second wheel 2131, a second shaft 2133, and a second traction disc 2135.

[0103] The first rotating wheel 2111 is connected to the first end of the first rotating shaft 2113, serving as an operating handle mounted on the first rotating shaft 2113; the first traction disc 2115 is located in the middle of the first rotating shaft 2113. Figure 18 In the middle), the first rotating shaft 2113 passes through the frame structure of the support member 2300, and its end, that is, the second end of the first rotating shaft 2113 ( Figure 18 The first brake hole 2510 of the body 2500 is fitted into the right side of the first brake hole 2510. This first brake hole 2510, as a specially designed force-bearing structure, has a diameter that varies in the swing direction. This varying diameter causes the first rotating shaft 2113 to be compressed to different degrees at different swing positions within the first brake hole 2510. The second rotating wheel 2131 is connected to the first end of the second rotating shaft 2133, and the second rotating shaft 2133 and the first rotating shaft 2113 are coaxial. The first end of the second rotating shaft 2133 is fitted into the second brake hole 2530 on the body 2500. In this embodiment, as a most likely arrangement, the coaxiality is achieved by the second rotating shaft 2133 being sleeved on the outer circumferential surface of the first rotating shaft 2113. The second traction disc 2135 is located at the middle position of the second rotating shaft 2133. Figure 18 (Middle). As can be seen from the figure, the second traction disc 2135 is positioned further back than the first traction disc 2115. Furthermore, the first rotating wheel 2111 is positioned further back than the second rotating wheel 2131. Of course, the coaxial arrangement of the first rotating shaft 2113 and the second rotating shaft 2133 can also be achieved in other ways, such as arranging them opposite each other from both ends. If this arrangement is adopted, the overall layout of the locking device will be significantly different from this embodiment, but its principle remains essentially the same.

[0104] After introducing the above-mentioned shafts and wheels, the structure of the traction disc will be introduced next. Since the second traction disc 2135 has the same structure as the first traction disc 2115, and the first traction disc 2115 has the same structure and function as the first traction disc 115 in the first embodiment of this application, the structure of the first traction disc 2115 and the second traction disc 2135 in this embodiment can be referred to the description of the first traction disc 115 in the first embodiment, and will not be repeated in this embodiment.

[0105] The following describes the support component 2300 and the body 2500; since the two are closely related, there is some overlap in the content of the description.

[0106] The support member 2300 includes: a support member body 2310; a first support portion 2311; a second support portion 2313; a notch 2315; a control member 2330; and a positioning shaft 2350.

[0107] The body 2500 includes: a first brake hole 2510; an elastic locking hole 2511; a U-shaped expansion joint 2513; a support hole 2515; a hole gap 2517; and a second brake hole 2530.

[0108] The body 2500, also referred to as the handle, serves as the handle of the endoscope as a whole. In this application, the body 2500 provides the positioning basis for the entire locking device 210.

[0109] The body 2500 is generally designed as two interlocking covers that can be disassembled according to assembly and repair needs. For the endoscope locking device 210 of this application, the relevant structure provided by the body 2500 is mainly the first brake hole 2510 and the second brake hole 2530. In this embodiment, the body 2500 is a hollow cylindrical shell made of plastic. The first brake hole 2510 is located on the surface of the body 2500 shell. The second end of the first rotating shaft 2113 is fitted into the first brake hole 2510. The first brake hole 2510 is an irregularly shaped hole with a special contour. On the one hand, it supports the first rotating shaft 2113, and on the other hand, it provides space for the swing of the first rotating shaft 2113 and achieves the effect of applying elastic force to the first rotating shaft 2113. Specifically, the first brake hole 2510, as a specially designed force-bearing structure, has a diameter that varies in the swing direction of the first rotating shaft 2113. When the second end of the first rotating shaft 2113 is in different support positions in the first brake hole 2510, it is subjected to different degrees of compression due to the change in the diameter of the first brake hole 2510, thereby bearing different radial pressures. It can also be understood that the first brake hole 2510 can apply elastic force to the first rotating shaft 2113 radially. Through the above structure, the rotation of the first rotating shaft 2113 obtains corresponding damping.

[0110] In this embodiment, as a specific implementation, the first braking hole 2510 serves as a force-bearing structure, specifically an irregularly shaped hole, including... Figure 16 The elastic locking hole 2511 and the U-shaped expansion joint 2513 shown in the figure Figure 16 (Top left), also includes the support hole 2515 on the right side, which is blocked by the first pivot 2113 (top left). Figure 16 (Top right); Reference Figure 16As illustrated in the diagram, the elastic locking hole 2511 is obtained by cutting the housing of the machine body 2500, and it has a hole diameter that varies in the swing direction of the first rotating shaft 2113. Figure 16 The support hole 2515 on the right side is obscured and not shown. The elastic locking hole 2511 on the left side includes a hole body capable of accommodating the first rotating shaft 2113, and a hole slit 2517 cut along the contour of the outer diameter of the hole. Through this cutting form, when the first rotating shaft 2113 swings to the left half of the first braking hole 2510 (elastic locking hole 2511), although the hole diameter provided by the elastic locking hole 2511 is relatively small, it will be squeezed open. The elastic deformation of the elastic locking hole 2511 generates elastic force, causing the first rotating shaft 2113 to bear radial pressure. Conversely, the support hole 2515 on the right side ( Figure 16 (The part that is obscured and not shown) has a relatively larger diameter. Figure 16 In the support hole 2515, the second end of the first rotating shaft 2113 is housed. When the first rotating shaft 2113 swings to this position, it will not experience significant radial pressure, but will only be supported. In addition, a U-shaped expansion joint 2513 is provided at the left end of the elastic locking hole 2511 in the swing direction. This expansion joint 2513 is also obtained by cutting the housing of the machine body 2500, which can increase the opening space of the elastic locking hole 2511. In summary, at the position of the elastic locking hole 2511, the first rotating shaft 2113 applies an elastic force to the first rotating shaft 2113 by means of the hole gap 2517 on its edge and the expansion and contraction of the expansion joint 2513. In this embodiment, the second end of the first rotating shaft 2113 is fitted into the elastic locking hole 2511 or supported in the support hole 2515. The second end of the first rotating shaft 2113 is located at different positions in the first braking hole 2510. The first braking hole 2510 applies different radial pressures to the second end of the first rotating shaft 2113, thereby obtaining corresponding damping for the rotation of the first rotating shaft 2113.

[0111] The second brake hole 2530 is also located on the surface of the housing 2500, and is disposed opposite to the first brake hole 2510 on the surface of the housing 2500; Reference Figure 17 The illustration in the image. Figure 17 for Figure 15 The diagram shows the structure of the locking device 210 rotated counterclockwise, with the first end of the locking device 210, i.e., the head end of the rotating wheel assembly 2100, facing outwards from the paper. For ease of observation, the first rotating wheel 2111 and the second rotating wheel 2131 are hidden in this diagram.

[0112] In this embodiment, the structure of the second brake hole 2530 is similar to that of the first brake hole 2510. The difference is that the first rotating shaft 2113 and the second rotating shaft 2133 pass through the second brake hole 2530 into the housing of the body 2500. The second brake hole 2530 is used to support or fit the first end of the second rotating shaft 2133 and provide space for the swing of the second rotating shaft 2133. The second brake hole 2530 has a diameter that varies in the swing direction of the second rotating shaft 2133 (the second rotating shaft 2133 swings synchronously with the first rotating shaft 2113) and has an elastic force applied radially to the second rotating shaft 2133. When the second end of the second rotating shaft 2133 is in different support positions in the second brake hole 2530, it bears different radial pressures, thereby providing corresponding damping for the rotation of the second rotating shaft 2133.

[0113] Figure 21 A structural diagram of the support member 2300 is shown below. Figure 21 For a detailed description of the support component 2300, please refer to [link / reference]. Figure 15 , Figure 22 . Figure 22 for Figure 21 Side view of the support member 2300.

[0114] As mentioned above, the support member 2300 includes: a support member body 2310; a first support portion 2311; a second support portion 2313; a notch 2315; a control member 2330; and a positioning shaft 2350.

[0115] The support body 2310 is a frame structure (hereinafter referred to as the support frame) to facilitate the overall floating support of the first rotating shaft 2113, the second rotating shaft 2133, the first traction disc 2115, and the second traction disc 2135 within the support frame of the support body 2310. A control component 2330 is connected to one side of the support frame of the support body 2310, extending out of the body 2500 to provide a surface for easy operation and gripping. On the other side of the support frame of the support body 2310 (the side opposite to the control component 2330), a component embedded within the body 2500 is also provided. The positioning shaft 2350, which intersects the axis of the first rotating shaft 2113, has a rotatable support connection structure at its end with the fitting part inside the body 2500. By rotating the control component 2330, the support frame of the support body 2310 can be rotated, causing the first rotating shaft 2113 and the second rotating shaft 2133 to swing. Through the swinging of the first rotating shaft 2113 and the second rotating shaft 2133, the position of the second end of the first rotating shaft 2113 in the first brake hole 2510 changes; the position of the first end of the second rotating shaft 2133 in the second brake hole 2530 changes.

[0116] In this embodiment, as a specific implementation, the support body 2310 is composed of a first support portion 2311 and a second support portion 2313; the first rotating shaft 2113 and the first traction disc 2115 are integrally floatingly disposed in the first support portion 2311; the second rotating shaft 2133 and the second traction disc 2135 are integrally floatingly disposed in the second support portion 2313; the support body 2310 is a C-shaped support frame structure, and a notch 2315 is provided on the C-shaped support frame, the notch 2315 being connected to the U-shaped expansion joint 2513. The configuration provides a swingable base for the first rotating shaft 2113, the second rotating shaft 2133, the first traction disc 2115, and the second traction disc 2135 as a whole. The C-shaped support frame is set inside the body 2500, with a control component 2330 at one end, which serves as an operating handle on the body 2500. The other end of the C-shaped support frame of the support body 2310 is provided with a positioning shaft 2350, which is fitted into the inner surface of the body 2500 shell, providing a rotatable base for the support body 2310.

[0117] When the endoscope is working, rotating the control component 2330 causes the C-shaped support frame of the support body 2310 to rotate. The first rotating shaft 2113, the first traction disc 2115, the second rotating shaft 2133, and the second traction disc 2135, all located within the support frame of the support body 2310, swing accordingly. During the swinging of the first rotating shaft 2113 and the second rotating shaft 2133, the position of the second end of the first rotating shaft 2113 in the first brake hole 2510 changes, and the first end of the second rotating shaft 2133... The position of the end in the second brake hole 2530 changes. The first brake hole 2510 and the second brake hole 2530 both have a diameter that changes in the swing direction and have an elastic force applied radially to each rotating shaft. Each rotating shaft is in a different support position in the first brake hole 2510 and the second brake hole 2530, and thus bears different radial pressures, thereby obtaining corresponding damping for the rotation of the first rotating shaft 2113 and the second rotating shaft 2133. Generally, the locking device 210 can have a non-locked state and a locked state.

[0118] The following are key references Figure 20 The working process of the locking device 210 is described in detail.

[0119] Figure 20 It shows Figure 15 A schematic diagram of the locking device 210 in the locked state. Figure 20 for Figure 15The diagram below shows the structure of the locking device 210 rotated clockwise so that the second end of the locking device 210, i.e., the first brake hole 2510, faces outwards from the paper. (Refer to the following...) Figure 20 This section briefly describes the working process of the locking device 210, focusing on the operation process of switching between the locked and unlocked states.

[0120] When the endoscope locking device 210 needs to be locked, the control component 2330 is rotated by a certain angle, which drives the support body 2310 to rotate, and at the same time drives the first rotating shaft 2113, the second rotating shaft 2133, the first traction plate 2115, and the second traction plate 2135 to swing as a whole by a certain angle; when the second end of the first rotating shaft 2113 swings to the end of the elastic locking hole 2511 with a smaller diameter, this end is provided with a U-shaped expansion joint 2513 and a hole gap 2517 ( Figure 20 (Left side position) Although the aperture provided by the elastic locking hole 2511 is relatively small, it will be squeezed open. The elastic force generated by its opening causes the first rotating shaft 2113 to bear a large radial pressure. The second end of the first rotating shaft 2113 is difficult to rotate at this position, or even cannot rotate. Correspondingly, the second rotating shaft 2133 also swings to one end of the elastic locking hole of the second braking hole 2530. The first end of the second rotating shaft 2133 is also subjected to a large radial pressure at this position. The first end of the second rotating shaft 2133 is difficult to rotate or cannot rotate at this position. The first traction disc 2115 and the second traction disc 2135 are locked in their respective positions, the locking device 210 enters the locked state, and the traction length of the traction wire related to the traction disc in the vertical and horizontal directions in the endoscope guide tube is fixed, that is, the angle of the endoscope lens is locked.

[0121] When it is necessary to unlock the endoscope locking device 210, the control component 2330 is rotated by a certain angle, which drives the support body 2310 to rotate, and at the same time drives the first rotating shaft 2113, the second rotating shaft 2133, the first traction plate 2115, and the second traction plate 2135 to swing as a whole by a certain angle; when the second end of the first rotating shaft 2113 swings to one end of the support hole 2515, the ( Figure 20The support hole 2515 at the right-side position has a larger diameter, resulting in very little radial pressure on the second end of the first rotating shaft 2113, providing only support. The second end of the first rotating shaft 2113 can rotate freely at this position. Correspondingly, the second rotating shaft 2133 also swings to one end of the support hole of the second brake hole 2530. At this position, the hole diameter is larger, resulting in very little radial pressure on the first end of the second rotating shaft 2133, allowing it to rotate freely as well. At these positions, the first traction disc 2115 and the second traction disc 2135 can rotate flexibly with the operator's manipulation of the first rotating wheel 2111 and the second rotating wheel 2131. The traction wire associated with the traction discs can be flexibly wound and unwound under their traction, allowing for flexible adjustment of the endoscope lens angle. Please refer to [reference needed]. Figure 20 It can be seen that the second end of the first rotating shaft 2113 is... Figure 20 When positioned, it is located inside the support hole 2515. Due to the obstruction of the line of sight by the first rotating shaft 2113, the support hole 2515 cannot be seen directly.

[0122] The third embodiment described above is a preferred embodiment, and obviously, other variations are possible based on its fundamental principle. For example, the rotary wheel assembly 2100 includes a first rotary wheel assembly 2110, meaning the locking device 210 can only adjust the endoscope angle in one dimension. Of course, there are other possible variations. For example, the first rotary wheel 2111 and the second rotary wheel 2131, as mentioned earlier, are in opposite positions, rather than being at the same end as in this embodiment.

[0123] Corresponding to the third embodiment described above, the fourth embodiment of this application provides another locking device.

[0124] The following combination Figures 15-22 The structure and working process are described. In this embodiment, components with the same function as those in the third embodiment described above are named in the same way as possible for ease of understanding; however, although the third and fourth embodiments 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 third embodiment.

[0125] The locking device 210' is typically used in testing scenarios. Referring to the process described in Embodiment 3, the first traction disc 2115 in the rotating wheel assembly 2100 is replaced with a first functional disc 2115' to enable various possible adjustments. It should be understood that the structure of the first functional disc 2115' can be adjusted according to the function and application scenario of the locking device 210'. This embodiment does not impose specific limitations.

[0126] The locking device 210' includes a first rotating wheel 2111, a first rotating shaft 2113, a support member 2300, and a body 2500; The first rotating wheel 2111 is connected to the first end of the first rotating shaft 2113, and the first rotating shaft 2113 is provided with a first function disk 2115'; the support member 2300 is disposed in the body 2500 of the locking device 210', the main body of the support member 2300 is a support frame, and the first rotating shaft 2113 is supported by the support frame; The swinging of the support frame causes the first rotating shaft 2113 to swing, and the first rotating shaft 2113 is subjected to different degrees of compression by the specially designed force structure due to its different swinging positions, thereby giving the first rotating shaft 2113 different degrees of clamping force and giving the rotation of the first rotating shaft 2113 the required damping; the rotation of the first rotating shaft 2113 is used to rotate the first function disk 2115', and the first traction wire is adjusted through the first function disk 2115', thereby adjusting the observation angle of the endoscope in the first dimension.

[0127] Optionally, the second end of the first rotating shaft 2113 is fitted into and supported by the body 2500 through a first brake hole 2510 provided on the body 2500. The size of the first brake hole 2510 allows the first rotating shaft 2113 to have a swinging space therein. The specially provided force structure is specifically the aperture of the first brake hole 2510 that varies in the swinging direction. This varying aperture causes the first rotating shaft 2113 to be compressed to different degrees at different swinging positions located in the first brake hole 2510.

[0128] The locking device 210' provided in the fourth embodiment described above may also include other necessary structures, such as detection equipment and display equipment for cooperating with the locking device. It should be understood that the working process of the locking device in this embodiment is similar to that in Embodiment 3; please refer to Embodiment 3 for further details.
