Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] As described in the background section, existing endoscope handles generally adopt a fixed shape design, which makes operation inconvenient. Operators cannot adjust their hand grip posture according to different application scenarios, thus affecting work efficiency.

[0026] Based on this, please refer to Figures 1-11The embodiments of the present invention provide an endoscope handle 100 and an endoscope 1000, which can effectively improve the aforementioned technical problems. Specifically, they enable rapid adjustment and locking of the handle, adapting to the operator's hand grip posture according to different application scenarios, thus improving operational flexibility and work efficiency, and allowing the endoscope 1000 to be flexibly applied to various work scenarios. The endoscope handle 100 and endoscope 1000 will be described in detail below.

[0027] Please refer to Figure 1 , Figure 1 This is a partial structural diagram of the endoscope 1000 provided in this embodiment, combined with... Figure 1 The endoscope 1000 includes an endoscope handle 100 and an insertion part 200, with the distal end of the endoscope handle 100 connected to the insertion part 200. As will be readily apparent to those skilled in the art, the distal end of the insertion part 200 also includes a curved portion and a pointed end portion. The insertion part 200 contains a traction wire that drives the curved portion to bend, and the pointed end portion has other structures such as a camera unit and a light source; these will not be elaborated upon in this embodiment.

[0028] Please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the first usage state of the endoscope handle 100 provided in this embodiment. Figure 3 This is a schematic diagram of the second usage state of the endoscope handle 100 provided in this embodiment, combined with... Figures 1-3 The endoscope handle 100 includes a first handle 10, a second handle 20, and a locking mechanism 30. One end of the second handle 20 is rotatably engaged with the first handle 10, and the other end of the second handle 20 is used to connect with the insertion part 200. The locking mechanism 30 is disposed at the rotatable engagement point between the first handle 10 and the second handle 20 and is used to lock and fix the first handle 10 and the second handle 20.

[0029] It is easy to understand that, Figure 2 The endoscope handle 100 shown can be understood as a handle in a vertical position, that is, the first handle 10 and the second handle 20 are set horizontally on the same horizontal line, which can be applied to scenarios where it is necessary to explore the internal structure. Figure 3 The endoscope handle 100 shown can be understood as a gun-style handle, that is, the first handle 10 and the second handle 20 are at a certain angle, which can be used to detect scenarios with complex internal structures. Of course, at this time, the operator can hold the first handle 10 more comfortably.

[0030] In other words, by rotating the first handle 10 and the second handle 20 together, and by locking the first handle 10 and the second handle 20 together with the locking mechanism 30, the endoscope handle 100 can be quickly adjusted and locked. The operator can adjust the hand position according to different application scenarios to adapt to the hand grip posture, thereby reducing the operator's workload, improving operational flexibility and work efficiency, and enabling the endoscope 1000 to be flexibly applied to a variety of work scenarios.

[0031] It should be noted that the "rotational fit" mentioned above can be a clearance fit between the shaft and the shaft hole. That is, a shaft is provided on one of the first handle 10 and the second handle 20, and a shaft hole is provided on the other, thereby allowing the first handle 10 and the second handle 20 to rotate relative to each other. Of course, a hinge can also be used to achieve a hinged fit between the first handle 10 and the second handle 20; rotation can also be achieved through the fit between the shaft and the rolling bearing; or a ball joint and a ball socket can be used to achieve universal rotation of the first handle 10 and the second handle 20.

[0032] Furthermore, in this embodiment, in addition to the rotational engagement of the first handle 10 and the second handle 20, the first handle 10 and the second handle 20 can also be detachably connected, that is, the first handle 10 and the second handle 20 can be detachably rotated together. This allows for easy disassembly and replacement of the first handle 10 and the second handle 20 with different sizes, enabling the use of different sized first handles 10 and second handles 20 together to further meet the usage requirements of different application scenarios and operators with different hand sizes, thereby further improving operational flexibility and work efficiency.

[0033] Meanwhile, during the use of the endoscope 1000, if either the first handle 10 or the second handle 20 becomes contaminated or damaged, only one of them needs to be replaced, which saves costs, improves utilization, and is more environmentally friendly. For example, in disposable medical endoscope applications, the first handle 10 can be used as a reusable component, while the second handle 20 can be used as a disposable component.

[0034] It should be noted that, to achieve a detachable rotatable connection between the first handle 10 and the second handle 20, a pin and pin hole connection can be used. Specifically, a pin is provided on one of the first handle 10 and the second handle 20, and a pin hole is provided on the other. The installation and removal of the first handle 10 and the second handle 20 are achieved by inserting and removing the pin and pin hole. Alternatively, the aforementioned connection between the rotating shaft and the rolling bearing can also achieve quick release; that is, the bearing cover can be removed first, and then the rotating shaft and the rolling bearing can be separated.

[0035] Please continue to combine Figure 2 and Figure 3In this embodiment, the endoscope handle 100 also includes an adjustment mechanism 40, which is located at the rotational engagement point between the first handle 10 and the second handle 20 and is spaced apart from the locking mechanism 30. The adjustment mechanism 40 is used to connect with the traction wire.

[0036] By connecting the adjustment mechanism 40 to the traction wire of the endoscope 1000, the bending angle of the curved portion at the distal end of the insertion part 200 can also be adjusted, making it more convenient for the operator to operate the endoscope 1000. In other words, during use, the operator can hold the first handle 10 with one hand, first loosen the first handle 10 and the second handle 20 using the locking mechanism 30, adjust them to a suitable gripping and detection position, and then lock the first handle 10 and the second handle 20 using the locking mechanism 30. Then, during use, the operator can adjust the bending angle of the curved portion by operating the adjustment mechanism 40 with their fingers. Since both the adjustment mechanism 40 and the locking mechanism 30 are located at the rotational engagement point of the first handle 10 and the second handle 20, it is more convenient for the operator to use, further improving work efficiency.

[0037] Please refer to Figure 4 and Figure 5 , Figure 4 This is a first-view assembly diagram of the rotating housing 12 and the ball-head housing 22 provided in this embodiment. Figure 5 This is a partially exploded view of the endoscope handle 100 provided in this embodiment, combined with... Figures 2-5 The first handle 10 includes a first gripping housing 11, a rotating housing 12 and a first rotating part 13 connected in sequence, and the second handle 20 includes a second gripping housing 21, a ball head housing 22 and a first bracket 23.

[0038] Specifically, one end of the second gripping housing 21 is connected to the ball head housing 22, and the other end of the second gripping housing 21 is used to connect to the insertion part 200. The first bracket 23 is disposed inside the ball head housing 22, and a connecting shaft 24 is provided on the side of the first bracket 23 near the locking mechanism 30. The connecting shaft 24 passes through the ball head housing 22. The first rotating part 13 is disposed on one side of the ball head housing 22 and is rotatably engaged with the connecting shaft 24. The end of the rotating housing 12 near the first rotating part 13 is slidably engaged with the end face of the ball head housing 22. The locking mechanism 30 is disposed at the rotatable engagement point between the first rotating part 13 and the connecting shaft 24, and is used to lock and fix the first rotating part 13 and the ball head housing 22.

[0039] It is understandable that by setting up the first grip shell 11 and the second grip shell 21, it is convenient for the operator to grip and operate; by setting up the first rotating part 13 to rotate and cooperate with the connecting shaft 24 on the first bracket 23, the rotational stability of the first handle 10 and the second handle 20 can be improved; at the same time, by sliding and cooperating with the spherical end face of the ball head shell 22 at one end of the rotating shell 12, the smoothness of the rotation of the first handle 10 and the second handle 20 can be ensured, thereby further improving the stable rotation of both.

[0040] Please refer to Figure 6 , Figure 6 This is a second-view assembly diagram of the rotating housing 12 and the ball-head housing 22 provided in this embodiment, combined with... Figure 2 , Figure 5 and Figure 6 To further improve the rotational stability of the first handle 10 and the second handle 20, the first handle 10 also includes a second rotating part 14. The second rotating part 14 is connected to one end of the rotating housing 12 near the ball head housing 22. The second rotating part 14 is spaced apart from the first rotating part 13, and the second rotating part 14 rotates with the side of the ball head housing 22. The first rotating part 13 and the second rotating part 14 are located on opposite sides of the ball head housing 22.

[0041] It should be noted that in this embodiment, the adjustment mechanism 40 is located at the rotational engagement point between the second rotating part 14 and the ball head housing 22, which can avoid interference between the adjustment mechanism 40 and the locking mechanism 30, and facilitate the adjustment and locking operations of the operator.

[0042] Please refer to Figure 7 , Figure 7 This is a partial structural cross-sectional view of the endoscope handle 100 provided in this embodiment, combined with... Figure 4 , Figure 5 and Figure 7 Specifically, the locking mechanism 30 includes a locking ring 31 and a locking nut 32. The locking ring 31 is disposed on one side of the ball head housing 22 and is located between the first rotating part 13 and the first bracket 23. The connecting shaft 24 passes through the locking ring 31 and is threadedly connected to the locking nut 32. The locking nut 32 is located on the side of the first rotating part 13 away from the locking ring 31, and the locking nut 32 is used to press and lock the first rotating part 13 and the locking ring 31 together or to separate and unlock them when the first rotating part 13 rotates relative to the connecting shaft 24.

[0043] It should be noted that the first rotating part 13 has a certain degree of elasticity. During the locking operation, by rotating the locking nut 32, the first rotating part 13 can be squeezed, causing it to undergo a certain elastic deformation and move towards the locking ring 31, thereby pressing and locking the first rotating part 13 and the locking ring 31 together. Of course, when it is necessary to unlock, by rotating the locking nut 32 in the opposite direction, the first rotating part 13 can return to its initial state under the action of its own elasticity and separate from the locking ring 31 to unlock, making the operation convenient and quick.

[0044] Further, please refer to Figure 8 , Figure 8 This is a partial structural diagram of the first handle 10 provided in this embodiment, combined with... Figure 5 and Figure 8 The locking ring 31 has a plurality of first teeth 311 on the side near the first rotating part 13, and the plurality of first teeth 311 are arranged sequentially along the circumference of the locking ring 31; the first rotating part 13 has a plurality of second teeth 133 on the side near the locking ring 31, and the plurality of second teeth 133 are arranged sequentially along the circumference of the first rotating part 13; the first teeth 311 are used to engage with the second teeth 133.

[0045] In other words, by setting the first tooth 311 and the second tooth 133 on the side where the locking ring 31 and the first rotating part 13 are close to each other, it can restrict the circumferential rotation of the locking ring 31 and the first rotating part 13, and also restrict the circumferential separation of the locking ring 31 and the first rotating part 13, thus achieving the effect of preventing disengagement and further improving the stability of rotation and locking.

[0046] Please combine Figures 5-7 Specifically, the second handle 20 also includes a third bracket 26, which is disposed inside the ball head housing 22 and located on the side of the first bracket 23 away from the connecting shaft 24. The adjustment mechanism 40 includes an adjustment handle 41, a rotating shaft 42, an adjustment hub 43, and a bushing 44. The rotating shaft 42 passes through the third bracket 26 and the ball head housing 22. The adjustment hub 43 and the adjustment handle 41 are respectively connected to the two ends of the rotating shaft 42, and the adjustment hub 43 is located on the side of the third bracket 26 closer to the first bracket 23. The adjustment hub 43 is used to connect with the traction wire. The adjustment handle 41 is located on the outside of the ball head housing 22, and the bushing 44 is sleeved on the rotating shaft 42. The second rotating part 14 is rotatably engaged with the bushing 44 and is located between the adjustment handle 41 and the outer wall of the ball head housing 22.

[0047] It is easy to understand that when the operator moves the adjustment handle 41, the adjustment hub 43 can be rotated via the rotating shaft 42, thereby driving the traction wire to move and adjusting the bending angle of the bending section. Furthermore, the rotational engagement between the second rotating part 14 and the bushing 44 ensures that the movement of the rotating shaft 42 is not affected during the rotation of the first handle 10 and the second handle 20, thus ensuring the accuracy of the bending adjustment.

[0048] Furthermore, by setting the adjusting hub 43 on the side of the third bracket 26 close to the first bracket 23, on the one hand, the internal space of the ball head housing 22 can be fully utilized, the overall volume of the handle can be reduced, the miniaturization design requirement can be met, and costs can be saved; on the other hand, it can also facilitate the connection between the adjusting hub 43 and the traction wire, and avoid interference between the rotating shaft 42 and the traction wire during the rotation process, thereby affecting the normal traction movement of the traction wire.

[0049] It should be noted that in this embodiment, the first bracket 23 and the third bracket 26 are fixedly connected, and the rotating shaft 42 and the connecting shaft 24 are coaxially arranged, which enables the locking mechanism 30 and the adjusting mechanism 40 to form a whole, improves the connection stability, and ensures the rotational stability of the first handle 10 and the second handle 20, thereby improving the overall structural strength and operational reliability of the endoscope handle 100.

[0050] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of the ball-head housing 22 provided in this embodiment, combined with... Figure 4 , Figure 5 and Figure 9 The ball head housing 22 has a first mounting hole 221 on one side. The second handle 20 also includes a first sealing plate 25, which is detachably connected to one side of the ball head housing 22 and is used to seal the first mounting hole 221. The connecting shaft 24 passes through the first sealing plate 25. The first rotating part 13 is located on the side of the first sealing plate 25 near the locking nut 32. The side of the first sealing plate 25 near the first rotating part 13 has a fixing groove 251, and the locking ring 31 is disposed in the fixing groove 251.

[0051] By providing a first mounting hole 221 and using a first sealing plate 25 to detachably connect to the ball head housing 22 to seal the first mounting hole 221, the first bracket 23 and the adjustment mechanism 40 can be easily installed and removed, improving installation and removal efficiency and facilitating later maintenance and replacement of parts. Simultaneously, by placing the locking ring 31 within the fixing groove 251, the locking ring 31 can also be easily installed and removed. Furthermore, the fixing groove 251 restricts the rotation of the locking ring 31, improving its installation stability and facilitating locking with the first rotating part 13.

[0052] Similarly, for easy installation and disassembly of the adjustment mechanism 40, please refer to... Figure 5 , Figure 6 and Figure 9 The ball head housing 22 has a second mounting hole 222 on the opposite side, that is, the second mounting hole 222 is opposite to the first mounting hole 221; the second handle 20 also includes a second sealing plate 27, which is detachably connected to the other side of the ball head housing 22 and is used to seal the second mounting hole 222; the rotating shaft 42 and the bushing 44 both pass through the second sealing plate 27, and the second rotating part 14 is located on the side of the second sealing plate 27 away from the third bracket 26.

[0053] Furthermore, in order to improve the sealing effect of the first mounting hole 221 and the second mounting hole 222, the endoscope handle 100 also includes a first sealing ring and a second sealing ring (not shown in the figure). The first sealing ring is disposed between the first sealing plate 25 and the inner wall of the ball head housing 22, and the second sealing ring is disposed between the second sealing plate 27 and the inner wall of the ball head housing 22.

[0054] In addition, in this embodiment, the endoscope handle 100 also includes a first side cover 61 and a second side cover 62. The first side cover 61 and the second side cover 62 are located on opposite sides of the ball head housing 22 and are respectively disposed corresponding to the first sealing plate 25 and the second sealing plate 27. The first side cover 61 is located between the locking nut 32 and the first sealing plate 25 and is used to cover at least a portion of the first rotating part 13. The second side cover 62 is located between the adjusting handle 41 and the second sealing plate 27 and is used to cover at least a portion of the second rotating part 14.

[0055] By setting the first side cover 61 and the second side cover 62, on the one hand, it can play a role in sealing and isolating the adjustment handle 41 to a certain extent, ensuring the rotation stability of the first rotating part 13 and the second rotating part 14; on the other hand, it can also make the endoscope handle 100 more beautiful, neat, dustproof and dirtproof.

[0056] Combination Figure 5 and Figure 8 In this embodiment, the first rotating part 13 has a first rotating hole 131, the second rotating part 14 has a second rotating hole 141, the connecting shaft 24 passes through the first transmission hole, and the bushing 44 passes through the second rotating hole 141. This arrangement facilitates the rotational engagement of the first handle 10 and the second handle 20, and also facilitates their disassembly and installation.

[0057] To further facilitate the disassembly and installation of the first handle 10 and the second handle 20, in this embodiment, the first rotating part 13 is further provided with a first notch 132, which communicates with the first rotating hole 131; the second rotating part 14 is further provided with a second notch 142, which communicates with the second rotating hole 141.

[0060] Please refer to Figure 10 and Figure 11 , Figure 10 This is an exploded view of the first handle 10 provided in this embodiment. Figure 11 This is a partial structural diagram of the endoscope handle 100 provided in this embodiment, combined with... Figure 8 , Figure 10 and Figure 11 The rotating housing 12 has an opening 121 at one end near the ball head housing 22. One end of the ball head housing 22 passes through the opening 121 and together with the rotating housing 12, forms a receiving cavity 122. The endoscope handle 100 also includes a signal connector 51 and a wire 52 connected thereto. Both the signal connector 51 and the wire 52 are housed within the receiving cavity 122. One end of the signal connector 51 passes through the ball head housing 22 and is used for electrical connection with the camera unit and light source inside the insertion part 200.

[0061] Specifically in this embodiment, the signal connector 51 is a waterproof connector, including a male connector and a female connector that can be separated from each other. The male connector is connected to the rotating housing 12 through the wire 52. The female connector is installed on the ball head housing 22. One end of the female connector that matches and connects with the male connector is exposed outside the ball head housing 22, and the other end of the female connector is wrapped inside the ball head housing 22 and is electrically connected to the camera unit and the light source through the wire.

[0062] In other words, the camera unit and the light source can be electrically connected to the signal connector 51 by passing wires sequentially through the insertion part 200, the second grip housing 21, and the ball head housing 22, and then the relevant signals can be transmitted through the wire 52. In this embodiment, by rotating the housing 12 and the ball head housing 22 to form a receiving cavity 122, the signal connector 51, wires 52, and other components located in the receiving cavity 122 can be waterproofed and dustproofed, meeting the requirements for sealing, protection, and disinfection of components located inside the endoscope handle 100.

[0063] Combination Figure 7 and Figure 9 To facilitate the installation of the signal connector 51, the ball head housing 22 is also provided with a third mounting hole 225, through which the signal connector 51 passes.

[0065] It is easy to understand that by setting up the second bracket 15, the installation of the control circuit board can be facilitated; at the same time, by electrically connecting the control circuit board to the wire 52, the control processing of signals transmitted from the camera unit and the light source can be realized.

[0066] Furthermore, in this embodiment, the endoscope handle 100 also includes an electrical plug 53, which is located at the end of the first gripping housing 11 away from the rotating housing 12, and is electrically connected to the control circuit board. By providing the electrical plug 53, it is convenient to connect to external devices (image processor, display, etc.) to display the images acquired by the camera unit.

[0067] It should be noted that in some other embodiments, wireless transmission can also be used to transmit signals to external devices. Specifically, the endoscope handle 100 may also include a wireless transmission module, which is disposed inside the first grip housing 11 and electrically connected to the control circuit board for wireless communication with external devices, thereby improving the portability of the endoscope 1000 and making it more convenient for operators to use.

[0068] Furthermore, in this embodiment, the endoscope handle 100 also includes a control button 54. The control button 54 is located at one end of the rotating housing 12 near the ball head housing 22, and is electrically connected to the control circuit board. It is readily understood that by placing the control button 54 on the rotating housing 12, when using the endoscope handle 100, the operator can hold the first grip housing 11 with one hand, then operate the adjustment handle 41 with their thumb and the control button 54 with their index finger, thus meeting ergonomic requirements and improving work efficiency.

[0069] Specifically, in this embodiment, the control button 54 is arranged opposite to the adjustment handle 41, that is, the control button 54 is located on the side of the rotating housing 12 away from the adjustment handle 41, which can be adapted to the position of the operator's index finger, further improving the ease of operation and work efficiency.
