Detailed implementation manners

[0026] The present utility model will be further described below with reference to the drawings.

[0027] Referring to Figures 1-7 As shown, the flexible ureteroscope sheath fixing device of this embodiment includes a first fixture 1, a standing frame 2, a supporting cantilever 3, a second fixture 4, and a detachable fixator 5. In this embodiment, there are three detachable fixators 5.

[0028] In this embodiment, the detachable fixator 5 includes a fixing cylinder 51 and a fixing screw 52. The outer contour of the radial cross-section of the fixing cylinder 51 is a regular hexagon, and two fixing screws 52 spaced along the axis of the fixing cylinder 51 are threadedly connected to three non-adjacent sides of the fixing cylinder 51.

[0029] In this embodiment, the first fixture 1 is used for clamping with the operating table. The first fixture 1 specifically includes a fixing frame 11 and a threaded abutting assembly 12. The fixing frame 11 is provided with a clamping groove 111 penetrating through the front side, the rear side, and the lower side, that is, the fixing frame 11 has an inverted U-shaped structure. The upper end of the fixing frame 11 is fixedly connected with a first connecting column 112 connected to the fixing cylinder 51.

[0030] In this embodiment, the threaded abutting assembly 12 is threadedly connected to one of the side plates of the fixing frame 11 and extends into the clamping groove 111. Specifically, the threaded abutting assembly 12 includes a first threaded rod 121, a first handle 122, and an abutting block 123. The first threaded rod 121 horizontally penetrates through one of the side plates of the fixing frame 11 and is threadedly connected thereto. The first handle 122 is fixedly connected to the outer end of the first threaded rod 121, and the abutting block 123 is fixedly connected to the inner end of the first threaded rod 121.

[0031] When clamping with the operating bed, the clamping groove 111 of the fixing frame 11 is buckled on the bed frame, and then the first handle 122 is rotated to drive the first threaded rod 121 by the first handle 122 to drive the abutting block 123 to move toward the bed frame until the abutting block 123 abuts tightly against the bed frame. In this way, the abutting block 123 and the fixing frame 11 can be clamped on the bed frame, and thus the first fixture 1 is clamped on the bed frame.

[0032] In this embodiment, there are three groups of threaded abutting assemblies 12, and the three groups of threaded abutting assemblies 12 are distributed in an isosceles triangle on the side of the fixing frame 11. Such a setting can abut against the bed frame through the three threaded abutting assemblies 12 to improve the clamping stability.

[0033] In this embodiment, the vertical frame 2 is fixedly connected to the first fixture 1 through a detachable fixer 5. Specifically, the vertical frame 2 is a round rod structure that can be inserted into the fixing cylinder 51. The vertical frame 2 is made of a rigid material, preferably hard plastic or stainless steel. When the vertical frame 2 is fixed to the first fixture 1, the fixing cylinder 51 of one of the detachable fixers 5 is sleeved on the first connecting column 112, and then the lower end of the vertical frame 2 is inserted into the fixing cylinder 51. After that, the first connecting column 112 and the vertical frame 2 are fastened respectively by three fixing screws 52 in the upper and lower layers. In this way, the vertical frame 2 is fixed to the first fixture 1 together.

[0034] In this embodiment, the support cantilever 3 is fixedly connected to the upper end of the vertical frame 2 through a detachable fixer 5. Specifically, the shapes of both ends of the support cantilever 3 match the shape of the fixing cylinder 51. The support cantilever 3 is a bendable and adjustable metal support hose, such as a common gooseneck tube. When the support cantilever 3 is fixed to the vertical frame 2, the fixing cylinder 51 of one of the detachable fixers 5 is sleeved on the outer side of the upper end of the vertical frame 2, and then one end of the support cantilever 3 is inserted into the fixing cylinder 51. After that, the support cantilever 3 and the vertical frame 2 are fastened respectively by three fixing screws 52 in the upper and lower layers. In this way, the support cantilever 3 is fixed to the vertical frame 2 together.

[0035] In this embodiment, the second fixture 4 is fixed to the end of the support cantilever 3 through a detachable fixator 5. The second fixture 4 is used to clamp the flexible ureteroscope sheath. The second fixture 4 specifically includes a housing 41, a second threaded rod 42, clamping blocks 43, and a second handle 44. A second connecting column 411 connected to the fixing cylinder 51 is fixedly connected to the upper end of the housing 41. The second threaded rod 42 horizontally penetrates the housing 41 and is rotatably connected to the housing 41. External threads are provided on both the left and right sides of the second threaded rod 42, and the two sections of external threads have opposite thread directions. The two clamping blocks 43 are respectively threadedly connected to the two sections of external threads and are slidably connected to the housing 41. The sliding direction of the clamping blocks 43 is parallel to the axial direction of the second threaded rod 42. There are two second handles 44, and the two second handles 44 are respectively fixedly connected to the two outer ends of the second threaded rod 42.

[0036] When fixing the flexible ureteroscope sheath, first reverse-rotate the second handle 44 to reverse-rotate the second threaded rod 42 to drive the two clamping blocks 43 to move away from each other. After the distance between the two clamping blocks 43 is greater than the diameter of the flexible ureteroscope sheath, place the flexible ureteroscope sheath between the two clamping blocks 43. Then, rotate the second handle 44 forward to drive the two clamping blocks 43 to move closer to each other until the flexible ureteroscope sheath is clamped, thus clamping the flexible ureteroscope sheath.

[0037] It is worth mentioning that V-shaped clamping grooves 431 are provided on the opposite sides of the two clamping blocks 43 in this embodiment. Such a setting can clamp the flexible ureteroscope sheath through four faces to stably fix the flexible ureteroscope sheath. In addition, a flexible soft pad can be provided inside the V-shaped clamping groove 431 to protect the flexible ureteroscope sheath while increasing the friction coefficient.

[0038] During use, the first fixture 1 is clamped on the bed frame, and the vertical frame 2 faces upward so that the support cantilever 3 and the second fixture 4 are at a high position. The support cantilever 3 can be bent at any angle so that the second fixture 4 is at any angle. The support cantilever 3 can also adjust the vertical position and horizontal position of the second fixture 4. The second fixture 4 is used to clamp the flexible ureteroscope sheath, so that the flexible ureteroscope sheath can be supported, replacing the doctor to hold the flexible ureteroscope sheath. This can reduce the operation difficulty of the operation, reduce the probability of misoperation, and thus improve the operation quality.
