To facilitate the observation of lesions, a locking device is installed at the rear end of the endoscope. In actual use, the distal end of the endoscope is inserted into the human body through a minimally invasive incision. After the distal end of the endoscope is adjusted to the appropriate position, the lens is then fixed at a certain angle. The locking device at the rear end of the endoscope controls the movement of the bendable section and adjusts the observation angle of the distal end of the endoscope to directly view the lesion at the relevant site. Therefore, the endoscope locking device is an important module in actual surgical procedures, playing a crucial role in enabling the observation of lesions.

[0040] The first embodiment of the present invention will be described in detail below with reference to Figures 1A to 7. The advantage of this embodiment is that it can provide a continuous and stable operation feel and has high adjustment reliability.

[0041] As shown in FIG. 1A, the left side of FIG. 1A is the first end of the locking device 10, i.e., the rotating wheel module 100 end, and the right side of FIG. 1A is the second end of the locking device 10, i.e., the brake module 100 end. Ki3 00 end, and in this figure, due to the viewing angle, Ki drive The operating module 500 is not shown and can be understood with reference to FIG. 1B and the subsequent schematic diagrams. Ki drive 2A is a structural schematic diagram of the locking device 10 in FIG. 1A at a different viewing angle, i.e., the brake Ki3 2A is a structural schematic diagram at a viewing angle with the 00 edge pointing out of the plane of the paper, and in this drawing, the locking device 10 is in an unlocked state. FIG. 3 is a structural schematic diagram of the left side of the locking device 10 in FIG. 2A, and FIG. 4 is a structural schematic diagram of the planar structure of the locking device 10 in FIG. 2A.

[0042] 1A and 1B, the locking device 10 includes a wheel module 100, a brake module 101, and a brake module 102. Ki3 00 and Bree Ki drive The actuator includes a module or component called a moving module 500.

[0043] The layout of the above components will be roughly explained. The rotating wheel module 100 is located at the first end (left side of FIG. 1A) of the locking device 10. Ki3 00 is located at the second end of the locking device 10 (right side in FIG. 1A) and Ki drive The actuating module 500 is similarly located at the second end of the locking device 10 (right side in FIG. 1A) and Ki3 It is installed at one end of the 00. Ki drive The moving module 500 is braked by fasteners 510. Ki3 00 and further Ki3 00 can be given a boost.

[0044] In this embodiment, the locking device 10 further includes a module called a handle. Although this module is not shown in the drawings of this application, those skilled in the art can easily understand the use of this module as it is a necessary module during the operation of the endoscope. The handle is actually the main body of the locking device 10 and provides a positioning base for each of the other components. The handle is actually the handle in the overall structure of the endoscope, and is generally designed as two interlocking covers that can be removed according to the need for assembly and repair. In this embodiment, the handle is a hollow circular shell made of plastic material, and includes the rotating wheel module 100, the brake Ki3 00, and in this embodiment, the modules related to the aircraft and the locking device 10 are mainly the first clamping post and the second clamping post, and the first clamping post and the second clamping post are used to brake the locking device 10 into the aircraft. Ki3 Achieve a fixed value of 00.

[0045] Next, the rotating wheel module 100 will be introduced, which includes a first rotating wheel module 110, a second rotating wheel module 130 and an isolation sheet 150.

[0046] Each component will be introduced in detail below.

[0047] The rotating wheel module 100 includes a first rotating wheel module 110, a second rotating wheel module 130 and an isolation sheet 150, the first rotating wheel module 110 includes a first rotating wheel 111, a first rotating shaft 113 and a first traction disc 115, and the second rotating wheel module 130 includes a second rotating wheel 131, a second rotating shaft 133 and a second traction disc 135.

[0048] The first rotating wheel 111 is connected to a first end of the first rotating shaft 113 and serves as an operating handle installed on the first rotating shaft 113. In this embodiment, the first rotating wheel 111 is installed at the first end of the first rotating shaft 113 (left side of FIG. 1A), the first traction disc 115 is installed at the other end of the first rotating shaft 113, i.e., the second end of the first rotating shaft 113 (right side of FIG. 1A), the second rotating wheel 131 is connected to a first end of the second rotating shaft 133, and the second rotating shaft 133 is coaxial with the first rotating shaft 113. In this embodiment, the most feasible arrangement is that the second rotating shaft 133 is fitted onto the outer circumferential surface of the first rotating shaft 113 to achieve the coaxiality, and the second traction disc 135 is installed at a position near the second end of the second rotating shaft 133. As can be seen from the figure, the second traction disc 135 is located closer to the first end than the first traction disc 115 (to the right in FIG. 1A ). The first rotating wheel 111 is located closer to the first end than the second rotating wheel 131. The first rotating wheel 111 has a protrusion extending to its second end, and the second rotating wheel 131 has a corresponding groove. The protrusion fits into the groove, thereby shortening the axial installation dimensions of the first rotating wheel 111 and the second rotating wheel 131. Of course, the coaxial arrangement of the first rotating shaft 113 and the second rotating shaft 133 may be completely different, such as an arrangement in which the first and second rotating shafts face each other. While such an arrangement would clearly distinguish the overall layout of the locking mechanism from this embodiment, the principles involved remain essentially the same.

[0049] After introducing the structure and connection relationship of each of the rotating shafts and rotating wheels, the structure of the traction disc will be introduced. Since the second traction disc 135 has a structure similar to that of the first traction disc 115, the structure of the second traction disc 135 can be explained by referring to the description of the first traction disc 115, and the explanation will be omitted here.

[0050] As shown in Figure 5, Figure 5 is a structural schematic diagram of the first traction disc 115 in the locking device 10. The figure also shows the first rotating shaft 113 connected to the first traction disc 115. Hereinafter, the specific structure of the first traction disc 115 will be described in detail with reference to Figure 5, and Figure 1A can also be referenced at the same time.

[0051] The first traction disc 115 is installed at the second end of the first rotating shaft 113, and the first traction disc 115 has a position for fixing the first traction sled 1153, and the first rotating wheel 111 controls the rotation of the first rotating shaft 113 to move the first traction disc 115 to rotate, and the rotation of the first traction disc 115 adjusts the extension distance of the first traction sled 1153, and the first traction sled 1153 can pull the lens of the endoscope, thereby adjusting the observation angle of the endoscope in the first dimension and making it an appropriate angle.

[0052] As shown in FIG. 5 , the first traction disc 115 includes a first traction disc groove 1151 , a first traction sled 1153 , a first traction hole 1155 and a first traction disc center hole 1157 .

[0053] The first traction disc 115 has a hollow disc structure, a first traction disc groove 1151 located on the outer circumferential surface of the first traction disc 115, a first traction sled 1153 enters the first traction disc 115 through the first traction disc groove 1151, and a symmetrical bidirectional first traction hole 1155 is provided on the circumferential surface of the first traction disc 115, which is used to receive and retract the first traction sled 1153. A first traction disc center hole 1157 is provided at the disc center position of the first traction disc 115, which is fitted and fixed on the first rotating shaft 113. This structure attaches the first traction disc 115 to the second end of the first rotating shaft 113.

[0054] One end of the first traction sled 1153 is fixed to the first traction disc 115 and can be inserted into the first traction disc groove 1151. By rotating the first traction disc 115, the extension and retraction of the first traction sled 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 sled 1153 in the first dimension, thereby adjusting its extension distance. As a possible configuration, in this embodiment, the first traction sled 1153 is composed of two traction sleds, and the observation angle in the first dimension is in the vertical direction. The two traction sleds of the first traction sled 1153 respectively control the observation angle in the vertical direction of the endoscope. In this embodiment, the configuration and control dimension of the first traction sled 1153 are merely schematic, and other possible configurations and control forms for the traction sled are not excluded.

[0055] The second traction disc 135 has a similar structure to the first traction disc 115, except that it is installed at a position closer to the second end of the second rotation shaft 133. The second traction disc 135 is used to fix the second traction sled, and the configuration of the second traction sled is the same as that of the first traction sled 1153. By rotating the second traction disc 135, the extension and retraction of the second traction sled can be adjusted, thereby adjusting the observation angle of the endoscope in the second dimension, for example, the observation angle in the left-right direction of the endoscope. Specifically, the rotation of the second traction disc 135 can control the extension and retraction of the second traction sled in the second dimension, thereby adjusting its extension distance.

[0056] In this embodiment, the first traction sled 1153 and the second traction sled are both embedded in the endoscope catheter, and the two ends of each traction sled are positioned at the bending end and the traction disk end of the endoscope catheter, respectively, with one end connected to the corresponding traction disk and the other end fixed within the catheter. Generally, when one end of a traction sled is pulled by the corresponding traction disk, when the traction disk rotates, the flexibility of the catheter will cause the bendable part of the catheter distal end to rotate through the traction sled, and further cause the lens end of the endoscope to rotate in a certain dimension (first or second), allowing the endoscope lens to be deflected at a certain angle and changing the viewing angle.

[0066] Next, Bree Ki drive To introduce and facilitate understanding of the operating module 500, reference may be made to the schematic in FIG. 1B and to FIG. 2A.

[0067] As shown in Figure 1B, Ki-Drive The module 500 includes a fastener 510 and a gripper 530 .

[0068] The fastener 510 is Kihon The frame structure of the body 310 is installed Ki-open The fastener 510 is located at the position of the opening 315. Kihon The brake is installed in a through hole in the body 310 and fastened by a fastener 510. First member 311 and brakes Second member 313 is connected, and a gripper 530 is provided at one end of the fastener 510, and the gripper 530 extends outside the shell of the locking device 10 body and is used by the operator of the locking device 10 to rotate the fastener 510. In a specific embodiment, the gripper 530 is a knob, and has a predetermined length in a radial direction perpendicular to the first rotation axis 113 of the knob that is significantly longer than the radius of the first rotation wheel 111. By rotating the knob, the fastener 510 is rotated, and the fastener 510 is braked. Kihon The blade rotates within the through-hole in the body 310. Ki3The biasing force applied to the brake can be adjusted. Ki3 00 changes the clamping force applied to the first rotating shaft 113 and the first traction disc 115 to bring the rotation damping of the first rotating shaft 113 into a first predetermined damping range, that is, to provide the damping required for the rotation of the first rotating shaft 113. Here, the first predetermined damping range is not specifically limited in the embodiments of the present application, and can be adaptively adjusted according to the actual usage conditions of the locking device 10.

[0069] For ease of understanding, we will now introduce in detail the fastener 510. The fastener 510 includes two implementations, which will be introduced below.

[0070] A first implementation of fastener 510 includes a stud 511 , an upper nut 513 and a lower nut 515 .

[0071] The stud 511 is the main body of the fastener 510, and the brake Kihon The stud 511 is provided with at least two threads of opposite rotational directions on the outer circumferential surface thereof, and is installed through a through hole in the body 310. An upper nut 513 and a lower nut 515 are further installed to couple with the stud 511, where the upper nut 513 is a brake. Ki-open The upper end of the opening 3151 is fixed to the upper side of the opening, and the lower nut 515 is Ki-open The upper nut 513 and the first segment of the stud 511 form a first screw pair, and the lower nut 515 and the second segment of the stud 511 form a second screw pair. The first screw pair and the second screw pair have opposite screw rotation directions, and by rotating the stud 511, the brake Ki3 The first screw pair and the second screw pair have different screw rotation directions, so when the stud 511 rotates in one direction, the upper nut 513 and the lower nut 515 move in the axial direction of the stud 511 in the direction in which they approach each other, or vice versa. Kihon Body 310 Brake Ki-openThe mouth 315 provides a grip on the first rotating shaft 113 and the second rotating shaft 133, increasing or decreasing the damping experienced by the rotating shafts.

[0072] In this embodiment, as another possible implementation, Kihon An internal thread is provided at the opening position of the frame structure of the body 310, which is coupled with the stud 511 in the through-hole, and the upper end opening 3151 of the brake opening and the first segment of the stud 511 are coupled (threaded) to form a third threaded joint, which is used to connect the brake Ki-open The lower end of the opening 3153 and the second segment of the stud 511 are connected (threaded) to form a fourth screw pair, and the third screw pair and the fourth screw pair have opposite screw rotation directions. When the stud 511 rotates, the surface thread of the stud 511 is broken. Ki-open Upper end of mouth 3151, Bra Ki-open The lower end of the mouth is connected to the mouth 3153, and Ki3 00, and the biasing principle is similar to the above-mentioned form using a nut.

[0073] By using the above two types of realization, when the endoscope is operated, the gripping portion 530 is rotated to move the stud 511 so as to rotate synchronously, thereby realizing the screwing operation of the stud 511 with the upper nut 513 and the lower nut 515 (first type of realization), or the screwing operation of the stud 511 with the brake Ki-open Upper end of mouth 3151, Bra Ki-open The screwing operation with the lower end opening 3153 of the opening (the second type of realization) is realized, and furthermore, the brake Kihon The biasing force applied to the body 310 is adjusted. Kihon The body 310 is a frame structure with a brake that opens it up and down. Ki-open The first rotary shaft 113 and the second rotary shaft 133 have a groove 315, and the outer circumferential surface of the first rotary shaft 113 and the second rotary shaft 133 are provided with a blade. Kihon The body 310 holds the above-mentioned brake. Kihon By adjusting the biasing force applied to the body 310, KihonBy changing the clamping force applied to the first rotating shaft 113 and the second rotating shaft 133 of the body 310, the rotational damping of the first rotating shaft 113 can be set within a first predetermined damping range, and the rotational damping of the second rotating shaft 133 can be set within a second predetermined damping range, thereby providing the necessary 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 when in an intermediate position between the unlocked and locked states. Here, the second predetermined damping range is not specifically limited in this application and can be adaptively adjusted according to the actual usage situation of the locking device 10. The first predetermined damping range may be the same as or different from the second predetermined damping range.

[0074] The operation process of the locking device 10 will be described in detail below in conjunction with FIGS. 2A, 4 and 7. FIG.

[0075] FIG. 2A shows a schematic diagram of the locking device 10 when it is in an unlocked state, FIG. 4 shows the process of switching the locking device 10 from the unlocked state to the locked state (FIG. 4 is a plan view corresponding to the locking device in FIG. 2A), and FIG. 7 shows a schematic diagram of the locking device 10 when it is in a locked state.

[0076] 2A and 7 show the locking device 10 in FIG. 1A rotated clockwise, and then the second end of the locking device 10, i.e., the brake Ki3 2A, 4, and 7, the operation of the locking device 10 will be briefly described, with emphasis on the process of switching between the locked state and the unlocked state.

[0077] When it is necessary to lock the endoscope locking device 10, by rotating the knob of the gripping portion 530 counterclockwise by a certain angle (from position B to position A as shown in FIG. 4), the knob of the gripping portion 530 moves the stud 511 to rotate counterclockwise, and a first screw pair is formed between the upper nut 513 and the first segment of the stud 511, and a second screw pair is formed between the lower nut 515 and the second segment of the stud 511. The first screw pair and the second screw pair have opposite screw rotation directions. Therefore, when the stud 511 rotates counterclockwise, the surface threads of the stud 511 screw into the upper nut 513 and the lower nut 515, and the upper nut 513 and the lower nut 515 move in the axial direction of the stud 511 toward each other, and the upper nut 513 and the lower nut 515 break. Kihon Since the brake is fixed to the inner surface of the through hole of the body 310, Ki-open The opening of the opening 315 is gradually reduced, and the break of the frame structure is Kihon The clamping force applied by the body 310 to the first rotary shaft 113 and the second rotary shaft 133 gradually increases, and the damping of the rotation of the first rotary shaft 113 and the second rotary shaft 133 gradually increases, causing the first rotary shaft 213 and the second rotary shaft 233 to gradually stop rotating due to the damping effect, and the first traction disc groove 2151 and the second traction disc groove 2351 stop the retraction and winding of the retraction threads in the left-right and up-down directions, so that the retraction lengths of the retraction threads in the up-down and left-right directions within the catheter are fixed, and the locking device 10 enters a locked state, i.e., the angle and direction of the endoscope lens are locked. Referring to Figures 2A and 7, the above process is the process of changing from Figure 2A to Figure 7, and the brake First member 311, brake Second member When 313 is in the position shown in FIG. 2A, the break formed between them Ki-open The opening 315 is large, and the break formed between them when they are in the position shown in FIG. Ki-open It can be seen that the mouth 315 is small.

[0078] When it is necessary to unlock the endoscope locking device 10, the knob of the gripping portion 530 is rotated clockwise by a certain angle (from position A to position B as shown in FIG. 4), whereby the gripping portion 530 moves the stud 511 in a rotational manner, and the surface threads of the stud 511 are screwed into the upper nut 513 and the lower nut 515, causing the upper nut 513 and the lower nut 515 to move in the direction away from each other along the axial direction of the stud 511, and the brake is released. Ki-open The opening of the opening 315 gradually increases, and the break of the frame structure Kihon The clamping force applied to the first and second rotary shafts 113 and 133 of the body 310 gradually decreases, and the damping of the rotation of the first and second rotary shafts 113 and 133 gradually decreases and disappears. The first and second rotary shafts 213 and 233 increase their rotation as the damping gradually decreases. When the damping disappears, the locking device 10 disengages from the locked state and enters the unlocked state. At this time, the first and second traction discs 215 and 235 can be flexibly rotated in response to the operator's manipulation of the first and second rotary wheels 211 and 231. The traction threads associated with the traction discs can be flexibly wound and retracted by the traction of the traction discs, thereby flexibly adjusting the angle of the endoscope lens. Referring to FIGS. 2A and 7, the above process is a transition from FIG. 7 to FIG. 2A. When in the position of FIG. 7, the brake First member 311 and brakes Second member The break formed between 313 Ki-open The opening 315 is small, and the break formed between them when they are in the position of FIG. 2A Ki-open It can be seen that mouth 315 is large.

[0079] Between the locked and unlocked positions, the grip 530 can be operated to position it between A and B, putting the locking device 10 into different damping states, thereby achieving different degrees of tightening for the rotating wheel adjustment according to the rotation needs of the rotating wheel. The locking device 10 allows the endoscope to be set to the appropriate state as needed when adjusting it. When unlocked, the rotating wheel allows the lens angle of the endoscope to be freely adjusted, and when locked, the endoscope is fixed and the lens angle does not change. Being in a damping state between the two positions provides the operator with the necessary feel for turning the rotating wheel, making it easier to operate.

[0080] As with the first embodiment, as a preferred embodiment, there may obviously be other variations on its basic principle. For example, the rotating wheel module 100 may include only the first rotating wheel module, i.e., the locking device 10 may adjust the angle of the endoscope in only one dimension. Of course, there are several other possible variations. For example, the first rotating wheel 111 and the second rotating wheel 131 described above may be located at opposite positions, rather than at the same end as in this embodiment.

[0081] Corresponding to the first embodiment described above, a second embodiment of the present application provides a locking device, and the purpose of providing this embodiment is to extend the principle of the first embodiment to other possible applications without limiting it to endoscopes.

[0082] The structure and operation process will be described below with reference to Figures 8 to 10, and Figures 1A to 7 in the first embodiment can also be referenced. In this embodiment, to facilitate understanding, parts having the same functions as those in the first embodiment are given the same names as far as possible. Although the first and second embodiments share common novelties, there are still significant differences. Therefore, the description of this embodiment will be based on the names provided in this embodiment and does not necessarily correspond to those of the first embodiment.

[0083] The locking device 10' is generally applied to detection scenes, and in combination with the process described in Example 1, the first traction disc 115 and the second traction disc 135 in the rotating wheel module 100 are replaced with a first function disc 115' and a second function disc 135' to realize various possible adjustment functions. It should be understood that the structures of the first function disc 115' and the second function disc 135' need to be structurally adjusted according to the function and application scene of the locking device 10'. This embodiment does not specifically limit the scope of the present invention.

[0084] The locking device 10' includes a first rotating wheel 111, a first rotating shaft 113, and a brake. Ki3 00, Bre Ki drive The system includes a motion module 500.

[0085] The first rotating wheel 111 is connected to a first end of the first rotating shaft 113, and a first functional disk 115' is installed at a position closer to the second end of the first rotating shaft 113. The first rotating wheel 111 controls the rotation of the first rotating shaft 113 and can move the first functional disk 115' to rotate. The rotation of the first functional disk 115' adjusts the first traction sled 1153, thereby adjusting the observation angle of the endoscope in a first dimension.

[0086] Bree Ki3 00 is a frame structure that holds the peripheral surface of the first rotating shaft 113 or the first functional disc 115', and the frame structure has a brake that opens it up and down. Ki-open It has a mouth 315 .

[0087] Bree Ki drive The moving module 500 has a fastener 510, which is a brake. Ki-open The brake is installed at one end of the opening 315 and fastened by a fastener 510. Ki3 The biasing force applied to the brake can be adjusted. Ki3 By changing the clamping force applied to the first rotating shaft 113 and the first functional disc 115' by 00, the rotational damping of the first rotating shaft 113 is brought within a first predetermined damping range, that is, the damping required for the rotation of the first rotating shaft 113 is provided.

[0088] The locking device 10' provided in the second embodiment may further include other necessary structures, such as a detection device and a display device for combining with the locking device. It should be understood that the operation process of the locking device in this embodiment is similar to that of the first embodiment, so please refer to the first embodiment and the description of this embodiment will be omitted. It should be emphasized that Figures 8 to 10 appear to have the same structure as Figures 1A, 2A, and 5 in the first embodiment, and merely illustrate that the components in the second embodiment have the same function as the components in the first embodiment, but this does not necessarily mean that the structures are the same. It should be understood that the components having the same function in the second embodiment and the first embodiment may have the same or different structures.

[0089] A third embodiment of the present application provides a locking device for use with another endoscope.

[0090] Hereinafter, the third embodiment of the present invention will be described in detail in conjunction with Figures 11 to 16. This embodiment has essentially the same principle as the first and second embodiments, that is, both are installed on at least one side of the outer circumferential surface of the rotating shaft (first rotating shaft and / or second rotating shaft) or the traction disc (or functional disc). Tabu By adjusting the rake, the desired damping of the rotation of the shaft is provided. Ki In a specific implementation, the third embodiment adopts a different structure, the advantage of which is that it is more simple in structure.

[0091] As shown in FIG. 11, it is a schematic cross-sectional view of the locking device 210 used in the endoscope provided in this embodiment, where the left side of FIG. 11 is the second end of the locking device 210, that is, the blade. Ki 211 is the first end of the locking device 210, i.e., the rotating wheel module 2100 end, and in this figure, the locking device 210 is in a locked state. FIG. 12 is a structural schematic diagram of the locking device 210 in FIG. 11 in an unlocked state. FIG. 13 is a structural schematic diagram of the locking device 210 in FIG. 11 in a locked state. Both FIGS. 12 and 13 show the second end of the locking device 210, i.e., the brake, after the locking device 210 in FIG. 11 has rotated counterclockwise. Ki 2 This is a schematic diagram of the structure at a viewing angle with the 300 edge facing out of the page.

[0092] As shown in FIG. 11, the locking device 210 includes a rotating wheel module 2100, a brake module 2101, and a brake module 2102. Ki 2 300, Brae Ki drive The actuator includes a moving module 2500 and a handle 2700 .

[0093] The arrangement of the above components can be roughly explained as follows: Ki 2 300 is disposed near the second end of the locking device 210 (left side in FIG. 11), and Ki drive The moving module 2500 is located at approximately the middle of the locking device 210 (the middle of FIG. 11), and the wheel module 2100 is located at the first end of the locking device 210 (the right side of FIG. 11). Ki 2 300 and Brake Ki drive The brake drive module 2500 is connected by a drive member body 2510. Ki 2 300 provides rotational damping to the rotating wheel module 2100.

[0094] In this embodiment, the handle 2700 is actually the main body of the locking device 210 and provides a positioning base for each of the other components. It is called a handle because it is actually the handle in the overall structure of the endoscope, and its specific structure will be described later.

[0095] The rotating wheel module 2100 includes a first rotating wheel module 2110 , a second rotating wheel module 2130 , an isolation sheet 2150 and an O-shaped seal ring 2170 .

[0096] Each component will be introduced in detail below.

[0097] The rotating wheel module 2100 includes a first rotating wheel module 2110, a second rotating wheel module 2130, an isolation sheet 2150 and an O-shaped seal ring 2170, the first rotating wheel module 2110 includes a first rotating wheel 2111, a first rotating shaft 2113 and a first traction disk 2115, and the second rotating wheel module 2130 includes a second rotating wheel 2131, a second rotating shaft 2133 and a second traction disk 2135.

[0098] The first rotating wheel 2111 is connected to a first end of the first rotating shaft 2113 and serves as an operating handle installed on the first rotating shaft 2113. In this embodiment, the first rotating wheel 2111 is installed at the first end of the first rotating shaft 2113 (the right side in FIG. 11), the first traction disc 2115 is installed at the other end of the first rotating shaft 2113, i.e., the second end of the first rotating shaft 2113 (the left side in FIG. 11), the second rotating wheel 2131 is connected to a first end of the second rotating shaft 2133, and the second rotating shaft 2133 is coaxial with the first rotating shaft 2113. In this embodiment, the most feasible arrangement is that the second rotating shaft 2133 is fitted onto the outer circumferential surface of the first rotating shaft 2113 to achieve the coaxiality, and the second traction disc 2135 is installed at a position near the second end of the second rotating shaft 2133. As can be seen from the figure, the second traction disc 2135 is installed at a position further toward the first end (to the right in FIG. 11) than the first traction disc 2115. Also, O-shaped seal rings 2170 are fitted to the first rotation shaft 2130, and the O-shaped seal rings 2170 are arranged in two groups, with two in each group and adjacent to each other, where the O-shaped seal ring 2170-1 of the first group is located close to the first traction disc 2115 and further toward the second end (to the left in FIG. 11) than the first rotation shaft 2113, and the O-shaped seal ring 2170-2 of the second group is located close to the first traction disc 2115. 11 ), the first rotating wheel 2111 is located close to the second rotating shaft 2135 and closer to the first end than the second rotating wheel 2133, and the first rotating wheel 2111 is located closer to the first end than the second rotating wheel 2131, and the first rotating wheel 2111 is provided with a protrusion extending to the second end, and the second rotating wheel 2131 is provided with a corresponding groove, and the protrusion fits into the groove, thereby shortening the axial installation dimensions of the first rotating wheel 2111 and the second rotating wheel 2131. Naturally, the coaxial arrangement of the first rotating shaft 2113 and the second rotating shaft 2133 can be completely different, for example, they can be arranged opposite each other from both ends. If such an arrangement is adopted, the layout of the entire locking device will be clearly different from that of this embodiment, but the principle will not be essentially different.

[0099] Referring to FIG. 16, the first traction disk 2115 has a position for fixing the first traction sled 21153, and by rotating the first traction disk 2115, the extension distance of the first traction sled 21153 can be adjusted, and the first traction sled 21153 can pull the lens of the endoscope, thereby causing the endoscope to be at an appropriate angle in a dimension controlled by the first traction sled 21153.

[0100] 16 shows a structural diagram of the first traction disc 2115. The figure also shows a first rotating shaft 2113 connected to the first traction disc 2115. The specific structure of the first traction disc 2115 will be described in detail below in conjunction with FIG. 16, and reference can also be made to FIG. 11.

[0101] As shown in FIG. 16, the first traction disc 2115 includes a first traction disc groove 21151, a first traction sled 21153, a first traction hole 21155 and a first traction disc center hole 21157.

[0102] The first traction disc 2115 has a hollow disc structure, a first traction disc groove 21151 located on the outer circumferential surface of the first traction disc 2115, a first traction sled 21153 enters the first traction disc 2115 through the first traction disc groove 21151, and a symmetrical bidirectional first traction hole 21155 is provided on the circumferential surface of the first traction disc 2115, which is used to receive and retract the first traction sled 21153. A first traction disc center hole 21157 is provided at the disc center position of the first traction disc 2115, which is fitted and fixed on the first rotating shaft 2113. This structure attaches the first traction disc 2115 to the second end of the first rotating shaft 2113.

[0103] One end of the first traction sled 21153 is fixed to the first traction disc 2115 and can be immersed in the first traction disc groove 21151. The extension and retraction of the first traction sled 21153 can be adjusted by rotating the first traction disc 2115, thereby adjusting the observation angle of the endoscope in the first dimension; specifically, the rotation of the first traction disc 2115 can control the winding and retraction of the first traction sled 21153 in the first dimension, thereby adjusting its extension distance.

[0104] The second traction disc 2135 has a similar structure to the first traction disc, except that it is located closer to the second end of the second rotation shaft 2133. The second traction disc 2135 is used to fix the second traction sled, and by rotating the second traction disc 2135, the extension and retraction of the second traction sled can be adjusted, thereby adjusting the observation angle of the endoscope in the second dimension; specifically, the rotation of the second traction disc 2135 can control the winding and retraction of the second traction sled in the second dimension, thereby adjusting its extension distance. The traction sled is embedded in the endoscopic catheter, and its two ends are respectively positioned at the curved end and the traction disk end of the endoscopic catheter, with one end connected to the traction disk and the other end fixed within the catheter. Generally, one end of a traction sled is pulled by the traction disk, and when the traction disk rotates, the flexibility of the catheter causes the bendable part of the catheter's distal end to rotate via the traction sled, which in turn causes the lens end of the endoscope to rotate in a certain dimension (up and down or left and right), allowing the lens of the endoscope to be deflected at a certain angle and changing the viewing angle.

[0105] An isolation sheet 2150 is installed in the axial gap between the first traction disc 2115 and the second traction disc 2135 to isolate them.

The structure of the drive member 2510 will be referred to as the brake mechanism hereinafter. Ki 2 We will introduce it in detail after introducing the structure of the 300.

[0108] The handle 2700 is named after the handle of an endoscope, and corresponds to the body that provides the positioning base in this application. The handle 2700 is generally designed with two interlocking covers that can be removed as needed for assembly and repair.

In this embodiment, the handle 2700 is a hollow circular shell made of plastic material, and the fixing post 2710 is located on the inner surface of the handle 2700 shell and supports the brake. Ki 2 300, in this embodiment, the fixed post 2710 is a solid plastic cylinder, and the brake 2300 is rotatably fitted to the fixed post 2710 by its positioning hole 2370, thereby obtaining a rotatable mounting position.

[0109] Figure 14 shows the brake Ki 2 The structural diagram of the brake 300 is shown below. Ki 2 300 in detail, please refer to FIG. 11 and FIG.

[0110] As mentioned above, Ki 2 300 is a brake Kihon Body 2310, Bra Ki-depressed It includes a groove 2330 , an arc-shaped through hole 2350 and a positioning hole 2370 .

[0111] Bree Ki 2 300 is an arc plate structure in this embodiment, Ki 2 300 is installed on at least one side of the outer circumferential surface of the first rotating shaft 2113, Kihon Brake at the bottom of the body 2310 Ki-depressed The groove 2330 is installed and the brake Ki-depressed The inner surface of the groove 2330 is in contact with the outer circumferential surface of the first rotating shaft 2130 and / or the outer circumferential surface of the second rotating shaft 2140. Ki 2 300 bonding surface, Ki-depressed The inner surface of the groove 2330 is provided with surface grooves that increase frictional force so that it can be easily attached to the outer surface of the first rotating shaft 2113 and / or the second rotating shaft 2133. Ki-depressed The groove 2330 and the first rotating shaft 2113 and the second rotating shaft 2133 are in contact with each other via an O-shaped seal ring 2170, and the brake Ki-depressed The surface grain in the groove 2330 is Kihon By moving the body 2310, the O-shaped seal ring 2170 is pressed, and the rotation of the first rotating shaft 2113 and the second rotating shaft 2133 can be stopped. Kihon A positioning hole 2370 is provided at one end of the arcuate surface of the body 2310, and the positioning hole 2370 is rotatably fitted to a fixed post 2710 of the handle 2700, and the brake Kihon The body 2310 rotates around the positioning hole 2370 to swing around the fixed axis. KihonAn arc-shaped through-hole 2350 is provided on the arc surface of the body 2310, and the arm column 2519 is inserted into the arc-shaped through-hole 2350 and can slide within the arc-shaped through-hole 2350. Kihon As shown in FIG. 14, the bodies 2310 are each a first brake. Kihon Body 2310-1 and second brake Kihon The body 2310-2 is configured as two arc plates placed in parallel in front and behind.

[0112] Figure 15 shows the brake Ki drive 15 shows a structural diagram of a driving member 2510, which is a component of the moving module 2500. The specific structure of the driving member 2510 will be described in detail below in conjunction with FIG. 15, and FIG. 11 may also be referred to.

[0113] As shown in FIG. 15, the drive member 2510 includes a drive member outer edge platform 2511 , a drive member bore 2513 , a drive member body 2515 , an arm 2517 and an arm post 2519 .

[0114] The driving member body 2515 is a hollow tube located at the lower end of the driving member 2510. A driving member hollow hole 2513 is provided in the driving member body 2515. The driving member body 2515 is fitted onto the outer diameter surface of the second rotating shaft 2133 through the driving member hollow hole 2513. A driving member outer edge platform 2511 is provided symmetrically on the outer circumferential surface of the driving member body 2515. The driving member 2510 is fixed to the lower end of the shift lever 2530 via the driving member outer edge platform 2511. By shifting the shift lever 2530, the driving member 2510 can be moved to rotate. An arm 2517 is fixed to the tip (left side of FIG. 15) of the driving member body 2515 in the vertical direction, and an arm pillar 2519 is fixed to the upper tip of the arm 2517 (upper left side of FIG. 15). The arm pillar 2519 extends in the extension direction of the first rotating shaft 2113 and the second rotating shaft 2133, and supports the brake. Ki 2300, and by driving the swing of the shift lever 2530, the driving member 2510 is moved so as to rotate, and further the arm pillar 2519 is moved so as to slide within the arc-shaped through hole 2350.

[0115] When the endoscope is in operation, the shift lever 2530 is shifted to move the driving members 2510 so as to rotate synchronously, and the arm pillar 2519 slides within the arc-shaped through-hole 2350. Furthermore, the arm pillar 2519 moves along the arc-shaped through-hole 2350, driving the brake 2300 to swing around the positioning hole 2370, and the brake Ki 2 The O-shaped seal ring 2170 is pressed against the surface grooves on the inner surface of the brake groove 2330 in 300, and the brake Ki 2 This allows adjustment of the degree of tightness of the bond between 300 and the outer circumferential surface of the first rotating shaft 2113 and the outer circumferential surface of the second rotating shaft 2133, thereby providing desired damping to the first rotating shaft 2113 and the second rotating shaft 2133. Generally, by this adjustment, the locking device 210 can have an unlocked state and a locked state, and can provide different degrees of damping when in a position between the unlocked state and the locked state.

[0116] That's it, just a Ki 2 300, and in fact, it is an embracing brake with multiple contact surfaces. Ki It is also conceivable to use a brake pad to contact and bond the outer circumferential surface of the first rotating shaft 2130 and / or the outer circumferential surface of the second rotating shaft 2140 from multiple sides, thereby achieving a braking effect. Those skilled in the art will be able to design such a brake pad based on the technical knowledge in this field, taking inspiration from the embodiments disclosed above.

[0117] Hereinafter, the operation process of the locking device 210 will be described in detail mainly with reference to FIGS.

[0118] 12 is a schematic diagram of the locking device 210 in FIG. 11 in an unlocked state. FIG. 13 is a schematic diagram of the locking device 210 in FIG. 11 in a locked state. Both FIG. 12 and FIG. 13 show the locking device 210 in FIG. 11 after it has been rotated counterclockwise, and the second end of the locking device 210, i.e., the brake Ki 2 11 to 13, the operation process of the locking device 210 will be briefly described below, with emphasis on the operation process for switching between the locked state and the unlocked state.

[0119] When it is necessary to lock the endoscope locking device 210, the shift lever 2530 is rotated clockwise along the handle 2700 by a certain angle (from position A to position B as shown in FIG. 12), whereby the shift lever 2530 moves the driving member 2510 so as to rotate around the second rotation shaft 2133, and also drives the arm column 2519 of the driving member 2510 so as to slide within the arc-shaped through-hole 2350, thereby locking the brake. Ki 2 300 is rotated clockwise around the positioning hole 2370, and the brake Ki 2 Brae at 300 Ki-depressed The surface grooves on the groove 2330 cause the O-shaped sealing ring 2170 to press against at least one side of the outer periphery of the first rotary shaft 2113 and the second rotary shaft 2133, thereby contacting and pressing them together, thereby generating frictional force as the first rotary shaft 2113 and the second rotary shaft 2133 rotate. The frictional force stops the first rotary shaft 2113 and the second rotary shaft 2133 from rotating, and the first traction disc groove 21151 and the second traction disc groove 21351 stop the winding and retraction of the traction thread in the left-right and up-down directions. The traction length of the traction thread in the up-down and left-right directions within the catheter is fixed, and the locking device enters a locked state, thereby locking the angle and direction of the endoscope lens. Referring to Figures 12 and 13, the above process is the process of changing from Figure 12 to Figure 13, and the brake Ki-depressedIt can be seen that the groove 2330 does not contact the first rotation axis 2113 when in the position of Figure 12, but does contact the first rotation axis 2113 when in the position of Figure 13, and although the second rotation axis 2133 is blocked at that viewing angle, the actual change corresponds.

[0120] When it is necessary to unlock the locking device 210, the shift lever 2530 is rotated counterclockwise along the handlebar 2700 by a certain angle (from position B to position A as shown in FIG. 13), whereby the shift lever 2530 moves the driving member 2510 to rotate around the second rotating shaft 2133, and drives the arm pillar 2519 of the driving member 2510 to slide within the arc-shaped through-hole 2350, thereby causing the brake Ki 2 300 is rotated around the positioning hole 2370, and the brake Ki 2 Brae at 300 Ki-depressed When the surface grain on the groove 2330 is separated from the O-shaped seal ring 2170 and the frictional force applied to the first rotating shaft 2113 and the second rotating shaft 2133 is gradually reduced until it disappears, the locking device 210 is released from the locked state and enters the unlocked state. At this time, the first traction disc 2115 and the second traction disc 2135 can be flexibly rotated by the operator's operation on the first rotating wheel 2111 and the second rotating wheel 2131, and the traction threads associated with the traction discs can be flexibly wound in and out by the pulling of each traction disc, thereby flexibly adjusting the angle of the endoscope lens. Referring to Figures 12 and 13, the above process is a process of changing from Figure 13 to Figure 12, and the brake Ki-depressed It can be seen that the surface grain of the groove 2330 contacts the first rotation axis 2113 when in the position of Figure 13, but does not contact the first rotation axis 2113 when in the position of Figure 12, and although the second rotation axis 2133 is blocked at that viewing angle, the actual change corresponds.

[0121] Between the locked and unlocked positions, the shift lever 2530 can be operated to position it between A and B, placing the locking device in different damping states, thereby obtaining different tightening degrees of adjustment for the rotating wheel as needed. The locking device allows the operator to set it to the appropriate state as needed when adjusting the endoscope. When unlocked, the rotating wheel can be used to freely adjust the lens angle of the endoscope. When locked, the endoscope is fixed and the lens angle does not change. When in a damping state between the two, the operator can feel the required feel when turning the rotating wheel, making it easier to operate.

[0122] The principle of the above embodiment will be briefly explained below. The combination of the shift lever 2530 and the driving member 2510 forms a lever mechanism. The shift lever 2530 is long and corresponds to the long arm end of the lever. Therefore, by shifting the driving member 2510, the brake is driven via its arm pillar 2519. Ki 2 The 300 can be easily moved like a rocking motion, and conversely, the brake Ki 2 The swing of 300 makes it difficult to move the shift lever 2530, and the arm pillar 2519 Ki 2 300, and there is a large frictional force between them, and the shift lever 2530 is equivalent to providing a load that inhibits the movement of the brake. Ki 2 300 is not likely to move due to loosening, that is, the locking device has excellent locking properties, and once the shift lever 2530 is shifted to any of the pulled positions, it can be hung there in the absence of external force and will not easily loosen.

[0123] The first embodiment described above is a preferred embodiment, and obviously, there may be other variations on its basic principle. For example, the rotating wheel module 2100 may include only the first rotating wheel module, i.e., the locking device may adjust the angle of the endoscope in only one dimension. Of course, there are several other possible variations. For example, the first rotating wheel 2110 and the second rotating wheel 2120 mentioned above may be located at opposite positions, rather than at the same end as in this embodiment.

[0124] In the above embodiment, the locking device used in the endoscope further includes a brake. tree, Bree Ki drive The actuator modules are divided into two groups, each providing attenuation along a first rotation axis and a second rotation axis, and also allowing for individual control and adjustment of the observation angle in the first and second dimensions of the endoscope, the second dimension being in a different direction from the first dimension.

[0125] Here, Bre Ki 2 300 can be split from top to bottom along the position of the isolation sheet 2150 in FIG. 11, and the first break Ki Department and the second brace Ki Department The first brake is divided into two parts. Ki drive The position and structure of the brake drive module is similar to the brake drive module 2500 in FIG. 11 (right side of FIG. 11), and the second brake Ki drive The dynamic module is the first brake Ki drive The first brake can be located on the other side of the actuator module (left side in FIG. 11). Ki Department is installed on the outer peripheral surface of the first rotating shaft, and the second brake Ki Department is installed on the outer peripheral surface of the second rotating shaft, and the first brake Ki drive The dynamic module is the first brake Ki Department and a first brake driving module for adjusting the degree of tightness of the bond between the first brake and the outer peripheral surface of the first rotating shaft, thereby providing a desired damping to the first rotating shaft; rotation of the first traction disk is used to adjust the first traction sled, thereby adjusting the viewing angle of the endoscope in a first dimension; and the second brake driving module is used to adjust the second brake. Ki DepartmentThe degree of tightness of the bond between the second traction disk and the outer surface of the second rotating shaft can be adjusted to provide the desired damping for the second rotating shaft, and rotation of the second traction disk is used to adjust the second traction sled, thereby adjusting the viewing angle of the endoscope in the second dimension.

[0126] The preferred embodiment described above allows the endoscope to achieve independent adjustment of the viewing angle in one dimension while ensuring that the viewing angle in another dimension is determined.

[0127] The fourth embodiment of the present application provides an endoscope, the structure and operation of which will be described with reference to Figure 17, specifically in combination with Figures 11 to 16. To facilitate understanding, parts in this embodiment that have the same functions as those in the third embodiment will be given the same names as far as possible. Although the third and fourth embodiments share common novelties, there are still significant differences. Therefore, the description of this embodiment will be based on the names provided in this embodiment, and need not necessarily correspond to those of the third embodiment.

The catheter 90 itself is made of a flexible material, allowing it to adapt to the curved body cavity of the patient, and the bendable section 80 allows the lens 70 to adjust the observation angle at the lesion site. The handle 2700 is held and controlled by the surgical operator, and the surgical operator can use the shift lever 2530 to perform external control of the locking device 210 as needed, and further enable observation of the lesion site inside the patient's body from different angles.

[0133] Here, the endoscope 2 can bend the flexible traction sled 30 at any angle using the locking device 210, and the locking device 210 adjusts the extension length of the traction sled 30 to adjust the angle of the lens 70 at a fixed position.
