Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, specifically to a handle locking structure for an endoscope. Background Technology

[0002] In clinical treatment, when an endoscope is inserted into the human body for observation, examination and treatment, such as when treating the pharynx and bronchi, the tip of the flexible endoscope can be bent to observe the internal condition of the pharynx and bronchi in different directions.

[0003] According to patent publication number "CN219720629U", the endoscope angle adjustment locking mechanism and endoscope include: a handle body, a reel, and a locking member. The outer circumferential surface of the reel is provided with a plurality of first locking teeth, and the reel is rotatably connected to the handle body. The locking member is provided with second locking teeth, and the locking member is movably connected to the handle body.

[0004] This patent achieves locking of the thread reels. Existing endoscopes are used by adjusting the direction of the endoscope with a handle, and then locking the position after adjustment. However, most existing locking structures use toothed grooves and limiting teeth. But when adjusting the endoscope, two handles are required. When locking at the same time, the limiting teeth on the two threads may be misaligned. Simultaneous locking may also cause the direction of the endoscope to change, thus making it impossible to obtain an image at the desired position. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a handle locking structure for endoscopes, which solves the problem that the direction of the endoscope may change when locking the two lines using existing handle locking structures for endoscopes.

[0007] The locking mechanism includes a mounting plate, which is fixedly connected to the top of the inner wall of the housing. Two rotating shafts are rotatably connected to the front of the mounting plate, and gears are fixedly connected to the surfaces of the two rotating shafts. The two gears mesh and drive each other. A clamping rod is fixedly connected to one end of each rotating shaft in front of the gear.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The endoscope's handle locking structure provides a technical solution:

[0023] The first embodiment includes an outer shell 1 and an endoscope 2. An adjustment component 3 is provided inside the outer shell 1, and a locking mechanism 5 for locking the position of the adjustment component 3 is provided inside the outer shell 1.

[0024] The locking mechanism 5 includes a mounting plate, which is fixedly connected to the top of the inner wall of the outer shell 1. Two rotating shafts are rotatably connected to the front of the mounting plate, and gears 51 are fixedly connected to the surfaces of the two rotating shafts. The two gears 51 mesh and drive each other. A clamping rod 52 is fixedly connected to one end of each rotating shaft in front of the gears 51. A U-shaped groove 53 is opened at the other end of each clamping rod 52. Guide grooves 54 are opened on the front and back of the left clamping rod 52. A sliding rod 55 is slidably connected to the right side of the outer shell 1, and a fan-shaped block 56 is fixedly connected to the top and bottom of the sliding rod 55. Two guide rods 58 are fixedly connected to the surface of the sliding rod 55 inside the outer shell 1, and the two guide rods 58 are respectively located inside the two guide grooves 54. A cam handle 57 is rotatably connected to one end of the sliding rod 55 on the right side of the outer shell 1.

[0025] After the endoscope 2 has been adjusted in direction, the two spools can be quickly locked by rotating the cam handle 57 in the locking mechanism 5. There is no need to worry about misalignment when locking, thus avoiding any change in the direction of the endoscope 2 during locking and improving the reliability of the device during use.

[0026] The second embodiment differs from the first embodiment in that the adjustment component 3 includes an outer shaft 31, which is rotatably connected to the front of the outer shell 1 and extends into the interior of the outer shell 1. A first thread pulley 32 is fixedly connected to the surface of the outer shaft 31 inside the outer shell 1, and an inner shaft 33 is rotatably connected to the inner surface of the outer shaft 31. The inner shaft 33 passes through the outer shaft 31 and extends to a second thread pulley 34 fixedly connected to one end behind the outer shaft 31. A first handle 35 is mounted on the front end of both the outer shaft 31 and the inner shaft 33 via a mounting component 4. The first handle 35 connected to the outer shaft 31 is also mounted via the mounting component 4.

[0027] The mounting assembly 4 includes a pressure plate 41. Two L-shaped rods 42 are fixedly connected to the back of the pressure plate 41. The front of the first handle 35 has two circular grooves, and the back of the inner wall of each of the two circular grooves is fixedly connected to a limit spring 43. The end face of the inner shaft 33 has two L-shaped grooves 44 that cooperate with the L-shaped rods 42. The inside of the inner shaft 33 has an arc groove 45, and the L-shaped groove 44 and the arc groove 45 are connected.

[0028] The handle is installed using the installation component 4, which is convenient and quick, allowing for rapid replacement of the handle if it is damaged or severely worn.

[0029] In use, the two first handles 35 are rotated to adjust the direction of the endoscope 2. After adjustment, the cam handle 57 is rotated. The rotation of the cam handle 57 causes the slide rod 55 to move to the outside of the outer shell 1. The movement of the slide rod 55 causes the left clamping rod 52 to rotate through the guide rod 58. The rotation of the left clamping rod 52 drives the gear 51 to rotate. The rotation of the left gear 51 then transmits power to the right gear 51. At this time, the two clamping rods 52 approach each other and clamp onto the outer surfaces of the first thread pulley 32 and the second thread pulley 34, thereby locking them. In addition, when it is necessary to disassemble the first handle 35, the pressure plate 41 is rotated to align the pressure plate 41 with the L-shaped groove 44. At this time, the pressure plate 41 can be removed. After the pressure plate 41 is removed, the first handle 35 can be removed.
