Description

Technical Field

[0001] This invention belongs to the field of medical device assembly technology, and is particularly related to a cystoscope assembly device. Background Technology

[0002] A cystoscope, also known as a cystoscope endoscope, is a medical device used to examine and treat problems inside the bladder, diagnose bladder-related diseases, and perform treatments and surgeries. Existing cystoscopes include reusable cystoscopes and disposable cystoscopes, such as… Figure 1 As shown, a disposable cystoscope mainly includes a sheath body and an adjustment dial, flexible sheath, image connector, laser power connector, and water injection connector integrated within the sheath body. Currently, the various components inside the sheath body are usually assembled manually. During manual assembly, the flexible sheath and water injection connector must be picked up by hand and aligned with the inside of the sheath body. Although the assembler wears sterilized gloves during the assembly process, the gloves may become contaminated if not changed promptly or if the assembler comes into contact with other contaminated items. This contamination can then affect the flexible sheath and water injection connector. Since the flexible sheath needs to be inserted into the urethra and the water injection connector needs to be connected to the infusion device during cystoscopy, contamination of either could lead to urethral infection in the patient during the examination. Therefore, it is necessary to improve the assembly process by providing an assembly device that eliminates the need for the assembler to come into contact with the flexible sheath and water injection connector during the assembly of the disposable cystoscope. Summary of the Invention

[0003] To address the aforementioned deficiencies in the prior art, this application provides a cystoscope assembly device. Using this device to assemble a cystoscope eliminates the need for assembly personnel to contact the flexible sheath and water injection connector, thus preventing contamination of both.

[0004] To achieve the above objectives, the present invention employs the following techniques:

[0005] A cystoscope assembly device, comprising:

[0006] A pair of push plates, each having multiple first receiving slots arrayed along its length on its inner side for securing the outer shell of the cystoscope, and a pair of first pushing mechanisms vertically provided on the outer side of the pair of push plates.

[0007] The suspension mechanism includes a long strip-shaped support block and multiple sets of snap-fit ​​components. The support block is movably mounted on one side of a vertical plate. The top of the support block has multiple arc-shaped grooves arranged along its length, penetrating both sides of the support block, for accommodating the cystoscope's rotating shaft. The length of the arc-shaped grooves matches the distance between the cystoscope's adjustment dial and handwheel. Each set of snap-fit ​​components includes two arc-shaped snap-fit ​​housings, used to snap the cystoscope's image connector and laser power connector, respectively. Each snap-fit ​​housing has a vertically connected pull rod on its outer side. The pull rods pass vertically through the vertical plate and are connected to the same connecting plate. A second pushing mechanism is provided between the connecting plate and the vertical plate. Each snap-fit ​​housing has a push rod parallel to the pull rod. One end of the push rod is connected to one side of the vertical plate. When the cystoscope's outer shell is snapped into the first accommodating groove of a push plate near the snap-fit ​​component, the portion of the outer shell forming the second cavity on the cystoscope is symmetrical to the multiple sets of snap-fit ​​components. When the telescopic end of the second pushing mechanism is fully extended, the push rod passes through the inner side of the snap-fit ​​housing.

[0008] The linear mechanism, located above the suspension mechanism, is used to drive the suspension mechanism to move along the length of the push plate.

[0009] Furthermore, one side of the support block is connected to a sliding sleeve via a connecting block. The sliding sleeve is slidably connected to the vertical plate in the vertical direction. The connecting block is connected to a lifting mechanism.

[0010] Furthermore, the lifting mechanism includes a connecting rod, with both ends of the connecting rod hinged to the connecting block and the pull rod respectively via two hinge seats. When the telescopic end of the second pushing mechanism is fully retracted and the outer casing is locked in the first receiving groove, the side of the connecting rod near the vertical plate has a preset angle with the vertical plate, and the bottom height of the arc groove matches the bottom height of the connecting hole on the outer casing of the cystoscope. When the telescopic end of the second pushing mechanism is fully extended, the angle between the side of the connecting rod near the vertical plate and the vertical plate decreases, and the support block moves downward a preset distance.

[0011] Furthermore, the linear mechanism includes a slide rail and a T-shaped slider. A T-shaped groove is formed on the slide rail along its length direction. The T-shaped slider is slidably connected in the T-shaped groove. The bottom of the T-shaped slider is connected to the top of the vertical plate. A strip-shaped through groove is formed on the top of the slide rail along its length direction. A push block is provided in the strip-shaped through groove. The bottom of the push block is connected to the T-shaped slider. A cylinder is provided on the top of the slide rail. The telescopic end of the cylinder is connected to the push block. The telescopic movement direction of the telescopic end of the cylinder is parallel to the length direction of the push plate.

[0012] Furthermore, the upper part of the first receiving groove matches the shape of the outer shell portion forming the first cavity on the cystoscope. When the outer shell of the cystoscope is engaged in the first receiving groove, the outer shell portion forming the second cavity on the cystoscope is outside the first receiving groove and protrudes from the top of the push plate. The lower part of the first receiving groove matches the shape of the outer shell portion forming the upper part of the third cavity on the cystoscope. When the outer shell of the cystoscope is engaged in the first receiving groove, the bottom of the outer shell of the cystoscope protrudes from the bottom of the push plate.

[0013] Furthermore, each of the push plates is equipped with a support bar below it. On the side of the support bar facing the vertical plate, multiple second receiving grooves are arranged in an array along its length. The shape of the second receiving groove matches the shape of the lower part of the outer shell forming the third cavity on the cystoscope. Both support bars are slidably connected to a pair of first guide rods. The length direction of the first guide rods is perpendicular to the push plate. The first guide rods are fixed between the pair of support plates. Each end of the bottom of the push plate is provided with a vertical push post. Each end of the top of the support bar is provided with a first strip groove. The push post is located in the first strip groove, and the length direction of the first strip groove is perpendicular to the push plate. When the outer shell of the cystoscope is in the second receiving groove and the push post abuts against the end of the first strip groove away from the vertical plate, the outer shell of the cystoscope is outside the first receiving groove. When the outer shell of the cystoscope is in the second receiving groove and the push post abuts against the end of the first strip groove near the vertical plate, the outer shell of the cystoscope is in the first receiving groove.

[0014] Furthermore, one of the support bars is hinged at both ends to one end of each of the two fixed rods. The hinge axis of the fixed rods is vertical. A spring is provided between the fixed rods and the support bar. A rectangular protrusion is vertically provided on the side of the fixed rod near the support bar. The two sides of the rectangular protrusion away from the fixed rod have rounded corners. Both ends of the other support bar have interconnected fixed grooves and second strip grooves. The fixed groove and the second strip groove are connected to the first strip groove. The second strip groove is located on the side of the fixed groove near the vertical plate. The top height of the second strip groove is lower than the top height of the fixed groove, and the bottom height of the second strip groove is higher than the bottom height of the fixed groove. When the two push plates drive the outer shell to close, the rectangular protrusion is in the fixed groove. A push block is provided in the second strip groove. The side of the push block near the fixed groove has an inclined surface. The end of the inclined surface facing the second strip groove is inclined towards the fixed groove. The push block is connected to the push column on the same side and is used to push the protrusion in the fixed groove outward.

[0015] Furthermore, a pair of first pushing mechanisms are fixed to a pair of support plates, and a pair of second guide rods are provided between the support plates. A pair of push plates are slidably connected to the pair of second guide rods.

[0016] Furthermore, a pair of arc-shaped clips are provided axially on the inner side of the snap-fit ​​housing for snapping the cystoscope's image connector and laser power connector.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. When assembling a cystoscope using this device, the assembler only needs to fix the outer shell, image connector, laser power connector, and adjustment dial. The assembler does not need to come into contact with the flexible sheath and water injection connector, which can avoid contamination of the two components during the assembly process.

[0019] 2. During the separation of the push plate, a pair of support bars can provide support for the bottom of the outer shell, preventing the assembled cystoscope from falling due to its own weight, which facilitates the subsequent transfer of the cystoscope. Furthermore, the push plate can continue to drive the support bars to separate, making it easier to remove the assembled cystoscope. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0036] This application provides a cystoscope assembly device for mounting a disposable cystoscope, such as... Figure 1As shown, the disposable cystoscope includes a sheath body and an adjustment dial 106, a flexible sheath 108, an image connector 105, a laser power connector 104, and a water inlet connector 107 integrated within the sheath body. Adjustment wires 1061 are provided on both sides of the flexible sheath 108. One end of each adjustment wire 1061 extends out of the flexible sheath 108 and connects to the top of the adjustment dial 106. Rotating the adjustment dial 106 pulls the adjustment wires 1061, thereby controlling the direction of the other end of the flexible sheath 108. The other end of the flexible sheath 108 is outside the sheath body and contains a camera, a water inlet outlet, and a laser head. The water inlet outlet is connected to the water inlet connector 107 via a water outlet line, the camera is connected to the image connector 105 via an information transmission line, and the laser head is connected to the laser connector via a power line. The power line passes through the middle of the water inlet connector 107 and enters the flexible sheath 108. The sheath body includes a pair of symmetrically arranged outer shells 1, which are interlocked. A cylindrical first cavity 102 is formed in the upper part of each outer shell 1. A connecting hole 1021 and a through hole 1022 are respectively provided in the upper part of each outer shell 1. The first cavity 102 is used to accommodate an adjusting turntable 106. A rotating shaft 1063 is coaxially inserted through the adjusting turntable 106. One end of the rotating shaft 1063 is rotatably connected to the connecting hole 1021, and the other end is connected to a handwheel 1064. The handwheel 1064 protrudes from the through hole 1022 to facilitate control of the rotation of the adjusting turntable 106. Two arc-shaped second cavities 103 are formed at the top of the first cavity 102 and communicate with it. Each cavity 102 has a pair of snap-fit ​​pieces 1031 for snapping the image connector 105 and the laser power connector 104. The bottom of the first cavity 102 has a tapered cavity 101 with a diameter that gradually decreases downward. The tapered cavity 101 has a pair of first fixing parts 1011 with rectangular slots and a second fixing part 1012 with an arc-shaped slot. A pair of rectangular locking blocks 1062 are symmetrically slidably connected to a pair of adjusting wires 1061. The rectangular locking blocks 1062 are locked in the first fixing parts 1011. The water injection connector 107 is located directly above the flexible sheath 108. The water injection connector 107 is spindle-shaped and is snapped in the second fixing part 1012 by the arc-shaped snap-fit ​​parts 1072 provided on its periphery.

[0037] like Figures 2-8 As shown, a cystoscope assembly device includes: a push plate 2, a suspension mechanism 3, a linear mechanism 4, etc.

[0038] Specifically, there is a pair of push plates 2. Each push plate 2 has multiple first receiving slots 201 arrayed along its length on its inner side for securing the outer shell 1 of the cystoscope. A pair of first pushing mechanisms 202 are vertically arranged on the outer sides of the pair of push plates 2 for driving the pair of push plates 2 to move in opposite directions. The suspension mechanism 3 includes a long strip-shaped support block 305 and multiple sets of locking components. The support block 305 is movably positioned on one side of a vertical plate 303. Multiple arc-shaped slots 3051 are arrayed along the length of the top of the support block 305, penetrating both sides of the support block 305. The diameter of the arc-shaped slots 3051 matches the diameter of the rotating shaft 1063 on the adjusting turntable 106 in the cystoscope, for accommodating the rotating shaft 1063. The length of the arc-shaped slots 3051 matches the distance between the adjusting turntable 106 and the handwheel 1064 on the rotating shaft 1063. Each set of locking components... Each component includes two arc-shaped snap-fit ​​housings 301, which are used to snap the image connector 105 and the laser power connector 104 in the cystoscope, respectively. Each snap-fit ​​housing 301 has a pull rod 302 vertically connected to its outer side. The pull rod 302 passes vertically through the vertical plate 303 and is connected to the same connecting plate 309. A second pushing mechanism 304 is provided between the connecting plate 309 and the vertical plate 303. Each snap-fit ​​housing 301 has a push rod 307 parallel to the pull rod 302. One end of the push rod 307 is connected to one side of the vertical plate 303. When the outer shell 1 of the cystoscope is snapped into the first receiving groove 201 of the push plate 2 near the snap-fit ​​assembly, the part of the outer shell 1 forming the second cavity 103 on the cystoscope is symmetrical with the multiple sets of snap-fit ​​assemblies. When the telescopic end of the second pushing mechanism 304 is fully extended, the push rod 307 passes through the inner side of the snap-fit ​​housing 301.

[0039] In actual use, a pair of outer shells 1 are respectively snapped into the first receiving grooves 201 of a pair of push plates 2, and the outer shell 1 with the through hole 1022 is placed in the first receiving groove 201 of a push plate 2 away from the support block 305. The support block 305 is controlled to move vertically until the bottom height of the arc groove 3051 is the same as the bottom height of the connection hole 1021 of the outer shell 1 of the cystoscope. Then, the suspension mechanism 3 is controlled to move through the linear mechanism 4 until the arc groove 3051 is aligned with the connection hole 1021. Next, the image connector 105 and the laser power connector 104 of the cystoscope are respectively snapped into the two snap-fit ​​shells 301, and the part of the rotating shaft 1063 near the handwheel 1064 is placed in the arc groove 3051, so that the adjusting turntable 106 and the handwheel 1064 abut against the two sides of the support block 305, thereby fixing the adjusting turntable 106, and making the axis of the rotating shaft 1063 the same as the axis of the connection hole 1021 and the through hole 1022. Because a pair of adjusting wires 1061 connected to the adjusting turntable 106 are symmetrically arranged and pass through the arc-shaped locking part 1072, when the adjusting turntable 106, the image connector 105, and the laser power connector 104 are fixed, and the water injection connector 107 is in a static, naturally drooping state, the pair of adjusting wires 1061 will be symmetrical with respect to the flexible sheath 108. The water injection connector 107 will also be in a suspended vertical state because the power line connected to the laser power connector 104 passes through it. At this time, the rectangular locking block 1062 and the arc-shaped locking part 1072 will be aligned with the first fixing part 1011 and the second fixing part 1012 at the same time, and the flexible sheath 108 will be aligned with the bottom of the conical cavity 101 at the same time, achieving preliminary alignment. After initial alignment, a first pushing mechanism 202 is controlled to move a push plate 2 near the support block 305 inward a preset distance, causing the rotating shaft 1063 to insert into the connecting hole 1021, and causing the image connector 105 and laser power connector 104 to be engaged in the second cavity 103 of the corresponding housing 1. Then, the telescopic end of the second pushing mechanism 304 is controlled to extend, causing the engaging housing 301 to disengage from the image connector 105 and laser power connector 104. During this process, the push rod 307 will restrict the image connector 105 and laser power connector 104. The connector 104 moves along with the snap-fit ​​housing 301. The image connector 105 and the laser power connector 104 will not be disengaged from the second cavity 103 of the cystoscope housing 1 due to the friction of the snap-fit ​​housing 301. Then, the support block 305 is controlled to move downward, causing the rotating shaft 1063 to disengage from the arc groove 3051. The linear mechanism 4 is controlled to drive the suspension mechanism 3 to move outside the coverage area of ​​the side of the push plate 2. Finally, another second pushing mechanism 304 is controlled to drive another push plate 2 to move inward until multiple pairs of housings 1 are snapped together, thus completing the installation. During the installation process, only manual contact with the housing 1, image connector 105, laser power connector 104, and adjusting turntable 106 is required. Assembly personnel do not need to contact the flexible sheath 108 and water injection connector 107, thus avoiding contamination of the two components during assembly.

[0040] For details, please refer to Figure 3 , Figure 4 The inner side of the housing 301 is provided with a pair of arc-shaped clips 3011 along the axial direction for attaching the cystoscope's image connector 105 and laser power connector 104. One side of the support block 305 is connected to a sliding sleeve 3031 via a connecting block 306. The sliding sleeve 3031 is slidably connected to the vertical plate 303 in the vertical direction. The connecting block 306 is connected to a lifting mechanism. For more details, see [link to relevant documentation]. Figure 4 , Figure 8 , Figure 9 The lifting mechanism includes a connecting rod 308. The two ends of the pull rod 302 are hinged to the connecting block 306 and the pull rod 302 respectively through two hinge seats. The pull rod 302 can be set to multiple. In this embodiment, the number of pull rods 302 is set to two to improve the stability of the support block 305 during the up and down movement. When the telescopic end of the second pushing mechanism 304 is fully retracted and the outer shell 1 is locked in the first receiving groove 201, the side of the connecting rod 308 near the vertical plate 303 has a preset angle with the vertical plate 303, and the bottom height of the arc groove 3051 matches the bottom height of the connecting hole 1021 on the outer shell 1 of the cystoscope. When the telescopic end of the second pushing mechanism 304 is fully extended, the angle between the side of the connecting rod 308 near the vertical plate 303 and the vertical plate 303 becomes smaller, and the support block 305 moves downward a preset distance. In this way, the second pushing mechanism 304 can drive the locking shell 301 to move horizontally and drive the support block 305 to move vertically to a preset position at the same time.

[0041] For details, please refer to Figure 5 , Figure 6 The linear mechanism 4 includes a slide rail 402 and a T-shaped slider 3032. A T-shaped groove is formed along the length of the slide rail 402, and the T-shaped slider 3032 is slidably connected within the T-shaped groove. The bottom of the T-shaped slider 3032 is connected to the top of the vertical plate 303. A strip-shaped through groove 4021 is formed along the length of the top of the slide rail 402, and a push block 403 is provided within the strip-shaped through groove 4021. The bottom of the push block 403 is connected to the T-shaped slider 3032. A cylinder 401 is provided at the top of the slide rail 402, and the telescopic end of the cylinder 401 is connected to the push block 403. The telescopic movement direction of the telescopic end of the cylinder 401 is parallel to the length direction of the push plate 2. When it is necessary to control the suspension mechanism 3 to move along the length direction of the push plate 2, the telescopic end of the cylinder 401 is controlled to push the T-shaped slider 3032 to move.

[0042] For details, please refer to Figure 10 A pair of first pushing mechanisms 202 are fixed to the inner side of a pair of support plates 7. A pair of second guide rods 701 are provided between the support plates 7. A pair of push plates 2 are slidably connected to the pair of second guide rods 701 to improve the stability of the push plates 2 during movement.

[0043] For details, please refer to Figure 11 The upper part of the first receiving groove 201 matches the shape of the portion of the outer shell 1 forming the first cavity 102 on the cystoscope. When the outer shell 1 of the cystoscope is engaged in the first receiving groove 201, the portion of the outer shell 1 forming the second cavity 103 on the cystoscope is outside the first receiving groove 201 and protrudes from the top of the push plate 2. The lower part of the first receiving groove 201 matches the shape of the portion of the outer shell 1 at the upper part of the conical cavity 101 on the cystoscope. When the outer shell 1 of the cystoscope is engaged in the first receiving groove 201, the bottom of the outer shell 1 of the cystoscope protrudes from the bottom of the push plate 2. After multiple pairs of cystoscope outer shells 1 are closed and the cystoscope assembly is completed, the upper and lower parts of the outer shell 1 protruding from the push plate 2 can be fixed first. Then, a pair of push plates 2 are controlled to move outward to prevent the outer shell 1 from moving outward due to the friction of the push plate 2 during the outward movement of the push plate 2, which would cause the connection of the outer shell 1 to loosen.

[0044] Preferred options, please refer to Figures 10-13 Each push plate 2 has a support bar 5 below it. On the side of the support bar 5 facing the vertical plate 303, multiple second receiving grooves 501 are arrayed along its length. The shape of the second receiving grooves 501 matches the shape of the lower part of the outer shell 1 forming the conical cavity 101. Both support bars 5 are slidably connected to a pair of first guide rods 507. The length direction of the first guide rods 507 is perpendicular to the push plate 2. The first guide rods 507 are fixed between the pair of support plates 7. Each end of the bottom of the push plate 2 has a vertical pushing column 503. Each end of the top of the support bar 5 has a first strip groove 502. The pushing column 503 is located within the first strip groove 502, and the length direction of the first strip groove 502 is perpendicular to the push plate 2. When the outer shell 1 of the cystoscope is located within the second receiving groove 501, and the push... When the moving column 503 abuts against the end of the first strip groove 502 near the vertical plate 303, the outer shell 1 of the cystoscope is located inside the first receiving groove 201. The outer shell 1 can be fixed together by the receiving groove and the second receiving groove 501. When the outer shell 1 of the cystoscope is located inside the second receiving groove 501, and the pushing column 503 abuts against the end of the first strip groove 502 away from the vertical plate 303, the outer shell 1 of the cystoscope is located outside the first receiving groove 201. This ensures that when the push plate 2 moves outward to separate from the outer shell 1, the lower part of the outer shell 1 of the cystoscope is located inside the second receiving groove 501 and will not fall downward due to gravity. At this time, the assembled cystoscope is picked up, and then the second pushing mechanism 304 is controlled to continue to drive the push plate 2 to move outward. The pushing column 503 will push the support bar 5 to move outward, realizing the separation of the support bar 5.

[0045] For further optimization, please refer to Figure 14One of the support bars 5 has its two ends hinged to one end of each of the two fixed rods 6. The hinge axis of the fixed rods 6 is vertical. A spring 602 is provided between the fixed rods 6 and the support bar 5. A rectangular protrusion 601 is vertically provided on the side of the fixed rod 6 near the support bar 5. The two sides of the rectangular protrusion 601 away from the fixed rod 6 have rounded corners 6011. The other support bar 5 has a fixed groove 504 and a second strip groove 505 that are connected to each other at both ends. The fixed groove 504 and the second strip groove 505 are both connected to the first strip groove 502. The second strip groove 505 is located on the side of the fixed groove 504 near the vertical plate 303. The top height of the second strip groove 505 is lower than the top height of the fixed groove 504, and the bottom height of the second strip groove 505 is higher than the bottom height of the fixed groove 504. When the two push plates 2 drive the outer shell 1 to close, the rectangular protrusion 601 is in the fixed groove 504, which can... To prevent the outer shell 1 from being subjected to frictional force during the outward movement of the push plate 2, which would then exert an outward pushing force on the support bar 5 and cause the support bar 5 to also move outward and fail to provide support for the assembled cystoscope outer shell 1, a push block 506 is provided in each of the second strip grooves 505. The side of the push block 506 near the fixing groove 504 has an inclined surface 5061. The end of the inclined surface 5061 facing the second strip groove 505 is inclined towards the fixing groove 504. The push block 506 is connected to the push column 503 on the same side.
