Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application provides an operating handle, which is applied to an endoscope main unit. The operating handle facilitates medical personnel in examining affected areas using the endoscope. Specifically, medical personnel can hold the operating handle and insert the endoscope into the patient's nasal cavity or gastrointestinal tract, etc. Then, by moving the operating handle and pressing the buttons on it, the endoscope can capture images of the specific condition of the affected area, thereby facilitating precise treatment of the patient.

[0032] In some embodiments, reference is made to Figure 1 The operating handle 100 includes a mounting housing 200, a button unit 300, and a grip 400. Both the button unit 300 and the grip 400 are located in the mounting housing 200. The button unit 300 can perform different functions, such as taking a picture, switching light source modes, zooming in, or freezing. The grip 400 facilitates operation by medical personnel.

[0033] In some embodiments, reference is made to Figure 2 The mounting housing 200 includes a housing 10, and the button unit 300 includes a button module 20. The housing 10 is located at the farthest end of the mounting housing 200, and the button module 20 is disposed on the housing 10.

[0034] See Figure 3 The outer casing 10 is provided with a pressing part 30, a portion of which is located outside the outer casing 10, and another portion of which is located inside the outer casing 10. The outer casing 10 encloses a receiving space 11, and the interior of the outer casing 10 refers to the space within the receiving space 11. The pressing part 30 and the button module 20 cooperate to form a button unit 300.

[0035] refer to Figure 3 and Figure 4 The button module 20 includes a button 21, a flexible circuit board 22, and a support member 40. The button 21 is disposed on the surface of the flexible circuit board 22, and the side of the flexible circuit board 22 facing away from the button 21 is fixed to the support member 40. The button module 20 is disposed inside the housing 10, and the support member 40 is fixedly connected to the housing 10. The button 21 and the pressing part 30 are opposite to each other. There can be multiple buttons 21 and pressing parts 30. Multiple means two or more. In this embodiment, there are four buttons 21 and four pressing parts 30. In other embodiments, there can be two, three, five, or six buttons 21 and three pressing parts 30, etc.

[0036] When medical staff use the operating handle 100, they can apply force to the pressing part 30 with their fingers. After the pressing part 30 is pressed, it abuts against the button 21, causing a signal change in the button 21. This signal change is transmitted to the controller via the flexible circuit board 22, and the controller can control the corresponding devices to perform corresponding operations. For example, when medical staff operate the pressing part 30 to perform the magnification function, the button 21 to perform the magnification function will generate a signal change. This signal change is transmitted to the controller via the flexible circuit board 22, and the controller controls the endoscope to perform the magnification action.

[0037] In related technologies, button 21 needs to be built inside the pressing part 30. Then, one end of the signal wire extends into the pressing part 30 and is electrically connected to button 21, while the other end of the signal wire extends out of the pressing part 30 and is connected to the circuit board. This structure has a large number of signal wires and is complex, making disassembly very difficult during later maintenance.

[0038] In this application, button 21 is fixed to flexible circuit board 22, which in turn is fixed to support member 40. When assembling the operating handle 100, button 21, flexible circuit board 22, and support member 40 are integrated into a button module 20, which is then installed entirely inside the housing 10. That is, in this application, button 21 can be assembled onto flexible circuit board 22 outside the housing 10, and flexible circuit board 22 can be assembled onto support member 40 outside the housing 10. The external operating space is very large, thus greatly reducing assembly difficulty. The internal accommodating space 11 of housing 10 is relatively large, providing ample operating space when installing button module 20 inside the housing 10, allowing operators to quickly install button module 20 inside the housing 10. When button 21 needs repair, button module 20 can be easily removed from housing 10. Therefore, in this application, the assembly process is simple, disassembly and repair are convenient, and the cost of processing and repairing the operating handle 100 is reduced.

[0039] In some embodiments, reference is made to Figure 3 and Figure 4 The flexible circuit board 22 may include multiple flexible portions 23, and each flexible portion 23 may be provided with one or more buttons 21. In this embodiment, each flexible portion 23 may be provided with one button 21, and there may also be multiple pressing portions 30, with each pressing portion 30 corresponding to one of the multiple flexible portions 23.

[0040] In some specific implementation methods, refer to Figure 3 and Figure 4 The inner surfaces of the outer casing 10, adjacent or opposite, may be provided with pressing parts 30, and the outer surfaces of the support member 40, adjacent or opposite, may be provided with flexible parts 23.

[0041] In one specific implementation, refer to Figure 5 The outer casing 10 is generally a rectangular frame with an opening on one side. The inner wall surface of the outer casing 10 includes a first inner surface 12, a second inner surface 13 and a third inner surface 14. The first inner surface 12 and the second inner surface 13 are arranged opposite each other along the length direction of the outer casing 10. The third inner surface 14 is connected between the first inner surface 12 and the second inner surface 13. The third inner surface 14 and the opening of the outer casing 10 are opposite each other along the height direction of the outer casing 10.

[0042] It is understood that the inner wall surface of the outer casing 10 also includes a fourth inner surface 15 and a fifth inner surface 16, which are arranged opposite to each other along the width direction of the outer casing 10.

[0043] refer to Figure 6 The support member 40 is generally rectangular in shape. The support member 40 includes a first outer surface 41, a second outer surface 42 and a third outer surface 43. The first outer surface 41 and the second outer surface 42 are arranged back to back along the length direction of the support member 40, and the third outer surface 43 is connected between the first outer surface 41 and the second outer surface 42.

[0044] It is understood that the support member 40 also includes a fourth outer surface 44, a fifth outer surface 45, and a sixth outer surface 46. The fourth outer surface 44 and the fifth outer surface 45 are arranged back to back along the width direction of the support member 40, and the third outer surface 43 and the sixth outer surface 46 are arranged back to back along the thickness direction of the support member 40. The sixth outer surface 46 is located at the opening of the outer casing 10.

[0045] In some embodiments, the support member 40 may be an integrally formed component, with the first outer surface 41 to the sixth outer surface 46 located on the integrally formed support member 40.

[0046] In other embodiments, reference is made to Figure 3 and Figure 4 The support member 40 includes a first support portion 410 and a second support portion 420, which are separately disposed. The first support portion 410 is generally rectangular in shape, and the second support portion 420 is generally rectangular in shape. The first outer surface 41, the third outer surface 43, the fourth outer surface 44, the fifth outer surface 45, and the sixth outer surface 46 are all disposed on the first support portion 410. The second outer surface is disposed on the second support portion 420.

[0047] The first support portion 410 also includes a seventh outer surface 411, which is disposed back to back with the first outer surface 41. The second support portion 420 also includes an eighth outer surface 421, which is located on the side of the second support portion 420 that is away from the first support portion 410, and the eighth outer surface 421 is located on the side of the second support portion 420 that faces the first support portion 410, and the eighth outer surface 421 is opposite to the first outer surface 41.

[0048] refer to Figure 7 The flexible circuit board 22 extends along the length of the outer shell 10. The flexible circuit board 22 includes four flexible parts 23, each of which is provided with a button 21.

[0049] When the button module 20 is installed in the receiving space 11 of the housing 10, the first outer surface 41, the second outer surface 42, and the third outer surface 43 are respectively opposite to the first inner surface 12, the second inner surface 13, and the third inner surface 14. At least two of the first inner surface 12, the second inner surface 13, and the third inner surface 14 have corresponding pressing portions 30, and at least two of the first outer surface 41, the second outer surface 42, and the third outer surface 43 have corresponding flexible portions 23.

[0050] For example, the first inner surface 12 corresponds to two pressing parts 30, the second inner surface 13 corresponds to one pressing part 30, and the third inner surface 14 corresponds to one pressing part 30. Correspondingly, the first outer surface 41 corresponds to two flexible parts 23, the second outer surface 42 corresponds to one flexible part 23, and the third outer surface 43 corresponds to one flexible part 23. The four buttons 21 and the four pressing parts 30 correspond one-to-one.

[0051] Optionally, the flexible circuit board 22 may extend along the width direction of the housing 10. The flexible circuit board 22 includes a plurality of flexible parts 23 connected sequentially along the width direction of the housing 10. The plurality of flexible parts 23 may be fixed sequentially to the fourth outer surface 44, the third outer surface 43 and the fifth outer surface 45.

[0052] By providing flexible parts 23 on different outer surfaces of the support member 40 and pressing parts 30 on different inner surfaces of the housing 10, a larger number of pressing parts 30 and buttons 21 can be provided in a limited space, which not only satisfies the function of the operating handle 100, but also improves the structural compactness of the operating handle 100.

[0053] When the support member 40 is a one-piece molded component, all four flexible parts 23 are fixed to the one-piece molded support member 40. When the support member 40 includes a first support part 410 and a second support part 420 that are separately arranged, a portion of the flexible parts are disposed in the first support part 410, and another portion of the flexible parts are disposed in the second support part 420. For example, the first outer surface 41 of the first support part 410 corresponds to two flexible parts 23, and the third outer surface 43 of the first support part 410 corresponds to one flexible part 23. The second outer surface 42 of the second support part 420 corresponds to one flexible part 23.

[0054] In some embodiments, reference is made to Figure 4 and Figure 7The flexible part 23 is provided with a positioning hole 24 and a positioning post 25; the positioning post 25 passes through the positioning hole 24 and is fixed to the support member 40. The positioning post 25 and the positioning hole 24 cooperate to position the flexible part 23 on the support member 40, preventing the position of the flexible part 23 from deviating. The flexible part 23 can be bonded to the support member 40 with adhesive.

[0055] In some embodiments, reference is made to Figure 3 The operating handle 100 also includes a fixing member 50, and the support member 40 is fixed to the housing 10 by the fixing member 50. Fixing the support member 40 to the housing 10 by the fixing member 50 can increase the ease of assembly.

[0056] In some embodiments, reference is made to Figure 3 The fixing member 50 includes a first fixing part 51 and two second fixing parts 52, which are respectively fixed to opposite ends of the first fixing part 51. The fixing member 50 may be plate-shaped and extends along the width direction of the support member 40. The side surface of the fixing member 50 facing away from the opening of the housing 10 contacts the sixth outer surface 46 of the support member 40, which can reduce the space occupied by the fixing member 50 and increase the structural compactness of the operating handle 100.

[0057] Specifically, the two second fixing parts 52 are located on both sides of the support member 40 along the width direction, and each second fixing part 52 extends along the opening of the outer shell 10 toward the third inner surface 14 of the outer shell 10 and is fixed to the outer shell 10, thereby fixing the support member 40.

[0058] The fixing member 50 is disposed at the receiving space 11, and the support member 40 is disposed in the gap between the first fixing part 51 and the inner wall surface of the outer shell 10; specifically, the support member 40 is disposed between the first fixing part 51 and the third inner surface 14 of the outer shell 10, and two second fixing parts 52 are respectively fixed to the outer shell 10. By fixing the support member 40 to the outer shell 10 through the two second fixing parts 52, the stability of the support member 40 can be increased.

[0059] In some embodiments, reference is made to Figure 6 The support member 40 has through holes 47 on both sides. Specifically, the two through holes 47 are arranged at intervals along the width direction of the support member 40. One through hole 47 penetrates the second outer surface 42, the fourth outer surface 44 and the sixth outer surface 46, and the other through hole 47 penetrates the second outer surface 42, the fifth outer surface 45 and the sixth outer surface 46.

[0060] refer to Figure 5Two connecting protrusions 17 are provided on the inner wall surface of the outer casing 10; the two connecting protrusions 17 extend into the two through holes 47 respectively. Specifically, the two connecting protrusions 17 are arranged at intervals along the width direction of the outer casing 10, and both connecting protrusions 17 protrude from the third inner surface 14. Two second fixing parts 52 extend into the two through holes 47 respectively, and the two second fixing parts 52 are fixedly connected to the two connecting protrusions 17 respectively.

[0061] Both the connecting protrusion 17 and the second fixing part 52 can be cylindrical. The through hole 47 can be circular. Both the connecting protrusion 17 and the second fixing part 52 extend into the through hole 47 and are coaxial. Both the connecting protrusion 17 and the second fixing part 52 are provided with threaded holes, allowing a bolt to be inserted into the threaded holes for a threaded connection. Optionally, the connecting protrusion 17 and the second fixing part 52 can also be fixed by a snap-fit ​​and slot structure. For example, the connecting protrusion 17 has a snap-fit ​​and the second fixing part 52 has a slot, or the connecting protrusion 17 has a slot and the second fixing part 52 has a snap-fit, with the snap-fit ​​engaging in the slot to securely connect the connecting protrusion 17 and the second fixing part 52.

[0062] In some embodiments, reference is made to Figure 6 The support member 40 also has a receiving groove 48, which is recessed into the sixth outer surface 46 and communicates with two through holes 47. The fixing member 50 is located in the receiving groove 48, which can improve the structural compactness of the operating handle 100. The middle part of the receiving groove 48 narrows to form two limiting walls 482, which respectively contact the two sides of the first fixing part 51 to limit the fixing member 50. The two sides of the receiving groove 48 are wider, which facilitates the fixing member 50 to extend into the receiving groove 48.

[0063] In some embodiments, reference is made to Figure 3 and Figure 8 The first fixing part 51 is provided with a first connecting hole 53, which penetrates the first fixing part 51 along the thickness direction of the fixing member 50. The support member 40 is provided with a second connecting hole 481 on the side facing the first fixing part 51, and the second connecting hole 481 is recessed in the bottom surface of the receiving groove 48. The operating handle 100 also includes a connector (not shown), which is fixed in the first connecting hole 53 and the second connecting hole 481. Using the connector, the support member 40 and the fixing member 50 can be fixedly connected. Specifically, the first connecting hole 53 and the second connecting hole 481 can be threaded holes, and the connector can be a bolt. The connector can be screwed into the first connecting hole 53 and the second connecting hole 481 to increase the reliability of the support member 40.

[0064] In some embodiments, reference is made to Figure 6The support member 40 is provided with guide grooves 49. Specifically, there can be four guide grooves 49, which are located at the four corners of the support member 40. Two guide grooves 49 are recessed in the fourth outer surface 44 and penetrate the third outer surface 43 and the sixth outer surface 46. The other two guide grooves 49 are recessed in the fifth outer surface 45 and penetrate the third outer surface 43 and the sixth outer surface 46.

[0065] refer to Figure 5 The inner wall surface of the outer casing 10 is provided with guide members 18. Specifically, there are four guide members 18, all of which protrude from the third inner surface 14 of the outer casing 10. When the support member 40 is installed inside the outer casing 10, the guide members 18 extend into the guide groove 49 and slide within the guide groove 49.

[0066] The guide 18 and guide groove 49 work together to make it easier to install the support 40 onto the housing 10, thus improving assembly convenience.

[0067] In some embodiments, reference is made to Figure 5 and Figure 6 A support column 19 protrudes from the inner wall of the outer casing 10. The support column 19 and the guide member 18 are fixedly connected, and the height of the support column 19 is less than the height of the guide column. (Reference) Figure 6 The outer surface of the support member 40 is recessed with a support groove 491, which is connected to the guide groove 49. The depth of the support groove 491 is less than the depth of the guide groove 49. The support post 19 extends into the support groove 491 and abuts against the bottom surface of the support groove 491, thereby creating a gap between the inner wall of the outer casing 10 and the outer surface of the support member 40. This gap is used to accommodate the flexible circuit board 22 and the button 21, preventing the flexible circuit board 22 and the button 21 from being squeezed and failing. In addition, the support post 19 and the guide post are fixedly connected, and the support groove 491 and the guide groove 49 are connected, which saves space and improves the structural compactness of the operating handle 100.

[0068] In some embodiments, reference is made to Figure 8 The pressing part 30 includes a resilient keycap 31, a mounting bracket 32, and a push rod 33. The mounting bracket 32 ​​is fixed to the resilient keycap 31, and the push rod 33 is embedded in the mounting bracket 32, with one end of the push rod 33 protruding from the mounting bracket 32. The outer casing 10 is provided with a mounting hole 101 and a stepped surface 102. The mounting hole 101 penetrates the outer wall surface and the inner wall surface of the outer casing 10, and the stepped surface 102 is located within the mounting hole 101. Specifically, the mounting hole 101 may include a first hole and a second hole, the inner diameter of the first hole being larger than the inner diameter of the second hole, and the stepped surface 102 being formed between the first hole and the second hole.

[0069] The pressing part 30 is disposed in the mounting hole 101, and the elastic keycap 31 abuts against the stepped surface 102; one end of the push rod 33 extends into the interior of the housing 10 and is opposite to the key 21; the elastic keycap 31 can drive the push rod 33 to move relative to the mounting bracket 32, so that the push rod 33 contacts or moves away from the key 21. The pressing part 30 has a simple structure and responds quickly.

[0070] The elastic keycap 31 can be made of rubber. When a medical staff member presses the elastic keycap 31, the keycap 31 undergoes elastic deformation, causing the push rod 33 to move closer to the button 21. When the push rod 33 comes into contact with the button 21, the signal of the button 21 changes. This signal change is transmitted to the controller via the flexible circuit board 22, and the controller uses this signal to control the endoscope to perform corresponding operations. When the medical staff member releases the elastic keycap 31, the elastic keycap 31 returns to its original position, causing the push rod 33 to move away from the button 21, thus returning the push rod 33 to its original position.

[0071] In some embodiments, reference is made to Figure 9 The push rod 33 includes a first rod 34 and a second rod 35. One end of the first rod 34 extends into the mounting bracket 32, and the other end is embedded in the elastic keycap 31. One end of the second rod 35 extends into the mounting bracket 32, and the other end extends into the interior of the outer casing 10, opposite to the key 21. The end of the first rod 34 embedded in the elastic keycap 31 is spherical. The end of the first rod 34 facing the second rod 35 has a convex arc surface 36, and the end of the second rod 35 facing the first rod 34 also has a convex arc surface 36. The convex arc surfaces 36 of the first rod 34 and the second rod 35 abut against each other. The elastic keycap 31 can drive the first rod 34 to move relative to the mounting bracket 32, so that the first rod 34 drives the second rod 35 to contact or move away from the key 21.

[0072] When medical staff use an endoscope, the pressing parts 30 on the operating handle 100 are relatively far from their fingers. Therefore, it is necessary to improve the sensitivity of these pressing parts 30 to avoid difficulty in pressing them due to the distance. In this embodiment, both the first lever 34 and the second lever 35 are provided with convex arc surfaces 36, and the convex arc surfaces 36 of the two levers abut against each other. Regardless of the angle from which the medical staff applies force to the elastic keycap 31 to deform it, the elastic keycap 31 can drive the convex arc surface 36 of the first lever 34 to push against the convex arc surface 36 of the second lever 35, causing the second lever 35 to move closer to the button 21. This increases the sensitivity of the pressing parts 30 and reduces the difficulty of operation for medical staff.

[0073] In some embodiments, when the support member 40 is a one-piece molded component, the support member 40 can be fixed to the housing 10 using the aforementioned fastener 50. When the support member 40 includes a separately configured first support portion 410 and a second support portion 420, the first support portion 410 is fixed using the aforementioned fastener 50, while the second support portion 420 can be fixed using other structures.

[0074] Optionally, refer to Figure 3 , Figure 4 and Figure 5 The inner wall of the outer casing 10 is provided with a storage shell 103. For example, the storage shell 103 protrudes from the third inner surface 14 of the outer casing 10, and the storage shell 103 and the outer casing 10 can be integrally formed by injection molding. The second support part 420 is fixed inside the storage shell 103. At this time, the positional accuracy of the button 21 on the flexible part 23 on the second support part 420 and the pressing part 30 on the outer casing 10 is high, which can further improve the sensitivity of the pressing part 30.

[0075] The following details the reason why the pressing part 30 has high sensitivity when the second support part 420 is fixed by the housing 103:

[0076] The travel distance of the pressing part 30 is very small, typically 0.2mm. Therefore, the positional accuracy requirements for the pressing part 30 and the button 21 are very high. When fixed by the fastener 50, the fixing process is as follows: the button 21 is placed on the flexible part 23, then the flexible part 23 is placed on the support member 40, then the support member 40 is placed on the outer shell 10, and finally the fastener 50 is used to fix the support member 40 to the outer shell 10. In the above fixing structure, due to processing and assembly errors, the positional accuracy error between the button 21 and the pressing part 30 may be relatively large, potentially leading to a certain degree of reduction in the sensitivity of the pressing part 30.

[0077] For the pressing part 30 that is close to the medical staff's fingers, a certain degree of decrease in sensitivity may not affect the medical staff's operation. However, for the pressing part 30 that is farther away from the medical staff's fingers, a decrease in the positional accuracy of the button 21 and the pressing part 30 will lead to a certain degree of decrease in the sensitivity of the pressing part 30, which will seriously affect the medical staff's operation.

[0078] In this embodiment, the flexible part 23 corresponding to the pressing part 30, which is farther away from the medical staff's fingers, is fixed by the cooperation of the housing 103 and the second support part 420. Because the housing 103 and the outer shell 10 are integrally formed, compared with fixing by components such as the fastener 50, assembly errors are reduced, and the positional accuracy of the pressing part 30 and the button 21 can be guaranteed. In particular, for the pressing part 30, which is farther away from the medical staff's fingers, the improved positional accuracy can further enhance the sensitivity of the pressing part 30 and reduce the difficulty of operation for medical staff.
