Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an endoscope operating part. Furthermore, this utility model also relates to an endoscope including the aforementioned endoscope operating part. Background Technology

[0002] Endoscopes, as medical devices used for imaging examinations and treatments inside the human body, have a wide range of applications in clinical medicine.

[0003] An endoscope includes an operating section and an insertion section. The insertion section includes a bending section. Currently, in related technologies, the operating section includes a manual knob. The manual knob is connected to a steel wire rope via a mechanical transmission mechanism. The end of the steel wire rope away from the operating section is connected to the bending section, so that by operating the manual knob, the bending section is driven to bend via the steel wire rope.

[0004] However, in this type of structure, the bending angle of the bending part is adjusted entirely by manually turning the knob. When the angle of the bending part is not suitable, the manual knob needs to be repeatedly adjusted to fine-tune the position of the bending part, resulting in low adjustment efficiency.

[0005] Therefore, how to improve the efficiency of adjusting the angle of the curved part of the endoscope is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an endoscope operating part that can improve the efficiency of adjusting the angle of the curved part of the endoscope.

[0007] Another objective of this invention is to provide an endoscope including the aforementioned endoscope operating section, which has high efficiency in adjusting the angle of its curved section.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An endoscope operating unit includes:

[0010] Operating part body;

[0011] A drive mechanism is located within the operating part and is connected to a traction member, which is used to connect to the curved part of the endoscope.

[0012] A joystick assembly is provided on the operating part body and has a joystick cap exposed outside the operating part body;

[0013] The controller is connected to both the rocker assembly and the drive mechanism to control the drive mechanism to move according to the movement of the rocker assembly when the rocker cap is operated, so that the drive mechanism drives the curved part to bend through the traction member.

[0014] Optionally, the drive mechanism includes two output shafts located at the ends of the drive mechanism, and the two output shafts are respectively connected to the traction member. The two output shafts are synchronously linked and extend in opposite directions.

[0015] Optionally, the drive mechanism includes:

[0016] The power unit is used to output rotary motion;

[0017] The lead screw shaft is connected to the power assembly;

[0018] A lead screw nut is threadedly connected to the lead screw shaft, and both output shafts are connected to the same lead screw nut.

[0019] Optionally, the drive mechanism is equipped with a position sensor for detecting the position of the lead screw nut. The position sensor is connected to the controller to provide feedback control for the power assembly.

[0020] Optionally, the number of driving mechanisms is two, the two driving mechanisms are stacked along a first direction, and the output shafts at the same end of the two driving mechanisms are staggered along a second direction, the second direction is perpendicular to the first direction, and both the first direction and the second direction are perpendicular to the axial direction of the output shaft.

[0021] Optionally, the operating part body is provided with a fixed pulley, the fixed pulley is located at one end of the driving mechanism, and the traction member located at the same end of the driving mechanism as the fixed pulley is wound around the fixed pulley.

[0022] Optionally, the operating unit body is provided with an emergency window, and the emergency window is provided with a removable emergency cover. The emergency window corresponds to the towing member so that the towing member can be cut through the emergency window.

[0023] Optionally, the operating unit body includes:

[0024] The bottom shell, the drive mechanism and the controller are both located on the bottom shell;

[0025] The top cover is detachably connected to the bottom shell, and the rocker assembly is located on the top cover.

[0026] Optionally, the upper cover and the bottom shell, as well as the rocker cap and the upper cover, are sealed together.

[0027] An endoscope comprising any one of the above-mentioned endoscope operating parts.

[0028] The endoscope operating section provided by this utility model has the following beneficial effects:

[0029] In use, the user moves the rocker cap to allow the controller to obtain the motion information of the rocker assembly. Based on this information, the controller sends a control command to the drive mechanism, causing it to move and drive the traction component. This causes the traction component to pull the curved part of the endoscope to bend. When the curved part reaches the desired position, the user stops moving the rocker cap. At this point, the drive mechanism stops working and enters a self-locking state, ensuring that the position of the traction component no longer changes and thus locking the curved part in the target position.

[0030] In other words, the endoscope operating unit incorporates a rocker assembly, controller, and drive mechanism. The drive mechanism moves the traction component to adjust the bending section, enabling continuous adjustment of the bending angle. Furthermore, the bending section can be locked at any time, resulting in high positional accuracy, ease of use, and improved adjustment efficiency.

[0031] The endoscope provided by this utility model includes the aforementioned endoscope operating part and has the same beneficial effects as the aforementioned endoscope operating part. Attached Figure Description

[0047] 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 scope of protection of the present utility model.

[0048] The core of this invention is to provide an endoscope operating unit that improves the efficiency of adjusting the angle of the endoscope's curved section. Another core aspect of this invention is to provide an endoscope including the aforementioned endoscope operating unit, which has high efficiency in adjusting the angle of its curved section.

[0049] Please combine Figure 1 , Figure 2 and Figure 3This utility model provides an endoscope operating unit, including an operating unit body 1, a drive mechanism 2, a rocker assembly 4, and a controller 5. The drive mechanism 2 is located inside the operating unit body 1 and is connected to a traction member 3, which is used to connect the curved part of the endoscope. The rocker assembly 4 is located in the operating unit body 1 and has a rocker cap 41 exposed outside the operating unit body 1. The controller 5 is connected to the rocker assembly 4 and the drive mechanism 2 respectively, so that when the rocker cap 41 is operated, the drive mechanism 2 is controlled to move according to the movement of the rocker assembly 4, so that the drive mechanism 2 drives the curved part to bend through the traction member 3.

[0050] In use, the user moves the rocker cap 41 to enable the controller 5 to obtain the motion information of the rocker assembly 4. Based on the motion information of the rocker assembly 4, the controller 5 sends a control command to the drive mechanism 2, causing the drive mechanism 2 to move and drive the traction member 3 to move. This causes the traction member 3 to pull the curved part of the endoscope to bend. When the curved part reaches the appropriate position, the user can stop moving the rocker cap 41. At this time, the drive mechanism 2 stops working and is in a self-locking state, so that the position of the traction member 3 no longer changes, thus ensuring that the curved part is locked in the target position.

[0051] In other words, this utility model embodiment applies the rocker assembly 4, controller 5 and drive mechanism 2 to the endoscope operating part. The drive mechanism 2 drives the traction member 3 to move, thereby realizing the adjustment of the bending part. The bending angle of the bending part can be continuously adjusted, and the bending part can be locked at any time, resulting in high positional accuracy of the bending part, convenient use, and improved adjustment efficiency of the bending part.

[0052] It should be noted that the present invention does not limit the specific structure of the joystick assembly 4 or the interaction between the joystick assembly 4 and the controller 5. Those skilled in the art can refer to relevant technologies, such as the relatively mature game controllers in the prior art.

[0053] In addition, this embodiment does not limit the specific structure of the drive mechanism 2, as long as the drive mechanism 2 can drive the traction member 3 to move under the control of the controller 5.

[0054] Please refer to Figure 4 and Figure 5 In order to save space, in some embodiments, the drive mechanism 2 includes two output shafts 21, both of which are located at the ends of the drive mechanism 2, and the two output shafts 21 are respectively connected to the traction member 3. The two output shafts 21 are synchronously linked and extend and retract in opposite directions.

[0055] In other words, the drive mechanism 2 in this embodiment is a dual-output shaft drive mechanism 2. For ease of description below, as follows: Figure 4As shown, the two output shafts 21 of a drive mechanism 2 are referred to as the first output shaft 211 and the second output shaft 212, respectively. The traction member 3 connected to the first output shaft 211 is referred to as the first traction member 31, and the traction member 3 connected to the second output shaft 212 is referred to as the second traction member 32. Since the two output shafts 21 are synchronously linked and extend and retract in opposite directions, that is, when the first output shaft 211 extends, the second output shaft 212 retracts, and when the first output shaft 211 retracts, the second output shaft 212 extends. Thus, when the first output shaft 211 extends, the second output shaft 212 retracts. When shaft 212 retracts, the second traction member 32 drives the curved portion of the endoscope to bend in the first direction. At this time, the first traction member 31 moves together with the curved portion bending in the first direction to avoid interference with the bending portion bending in the first direction. When the first output shaft 211 retracts and the second output shaft 212 extends, the first traction member 31 drives the curved portion of the endoscope to bend in the second direction. At this time, the second traction member 32 moves together with the curved portion bending in the second direction to avoid interference with the bending portion bending in the second direction. The second direction is opposite to the first direction. It can be seen that by using dual output shafts, one drive mechanism 2 can realize the bending of the curved portion in two opposite directions. The drive mechanism 2 has a compact structure and occupies little space, which greatly solves the problem of limited space and difficult layout of the endoscope operating part.

[0056] It should be noted that the two output shafts 21 can be located at the same end of the drive mechanism 2, or they can be located at opposite ends of the drive mechanism 2. Considering the convenience of driving the two output shafts 21, in some embodiments, the two output shafts 21 are located at opposite ends of the drive mechanism 2.

[0057] like Figure 5 As shown, in order to facilitate the movement of the two output shafts 21, in some embodiments, the drive mechanism 2 includes a power assembly 22, a lead screw shaft 23 and a lead screw nut 24. The power assembly 22 is used to output rotational motion, the lead screw shaft 23 is connected to the power assembly 22, the lead screw nut 24 is threadedly connected to the lead screw shaft 23, and the two output shafts 21 are connected to the same lead screw nut 24.

[0058] In other words, this embodiment utilizes the power component 22 to drive the lead screw shaft 23 to rotate. When the lead screw shaft 23 rotates, under the constraint of the output shaft 21 and the housing of the drive mechanism 2, the lead screw nut 24 moves along the lead screw shaft 23. Since both output shafts 21 are connected to the same lead screw nut 24, when the lead screw nut 24 moves, one output shaft 21 extends, and the other output shaft 21 retracts. It can be understood that in this case, the two output shafts 21 are located at both ends of the drive mechanism 2, making them dual-output shafts at both ends. It can be seen that the drive mechanism 2 has a simple structure and is easy to implement. Moreover, the way the two output shafts 21 are connected to the same lead screw nut 24 makes the overall structure more compact, and the overall size of the drive mechanism 2 is small.

[0059] It should be noted that this embodiment does not limit the specific structure of the power component 22, as long as the power component 22 can output rotational motion. Figure 5 As shown, in some embodiments, the power assembly 22 includes a motor 221 and a reducer 222 connected to the motor 221, with the lead screw 23 connected to the reducer 222. That is, in this embodiment, the reducer 222 slows down the rotational motion output by the motor 221, ensuring the lead screw 23 has a suitable speed and thus guaranteeing motion stability. Please refer to [further details omitted]. Figure 5 In some embodiments, the lead screw shaft 23 is connected to the reducer 222 via a synchronous belt drive mechanism 25. The synchronous belt drive mechanism 25 includes a main synchronous pulley 251, a driven synchronous pulley 252, and a synchronous belt 253. The main synchronous pulley 251 is connected to the reducer 222, and the driven synchronous pulley 252 is connected to the lead screw shaft 23. The synchronous belt 253 is wound around the main synchronous pulley 251 and the driven synchronous pulley 252. This facilitates a reasonable layout of the relative positions of the lead screw shaft 23 and the reducer 222, and allows the lead screw shaft 23 to be arranged parallel to the motor 221 and the reducer 222. This saves space along the length of the lead screw shaft 23 in the drive mechanism 2, making the overall structural dimensions of the drive mechanism 2 more reasonable.

[0060] It should be noted that the above embodiments do not limit the specific structure of the motor 221. In some embodiments, the motor 221 is a coreless motor 221.

[0061] In addition, in order to achieve precise control of the drive mechanism 2, such as Figure 5 As shown, in some embodiments, the drive mechanism 2 is provided with a position sensor 26, which is used to detect the position of the lead screw nut 24. The position sensor 26 is connected to the controller 5 to provide feedback control for the power assembly 22.

[0062] It is understandable that the position of the lead screw nut 24 reflects the position of the two output shafts 21, and the position of the two output shafts 21 determines the bending angle of the bent part. Therefore, in this embodiment, the position sensor 26 is used to detect the position of the lead screw nut 24, and the detection signal of the position sensor 26 is sent to the controller 5 to realize feedback control of the power component 22, that is, to realize closed-loop control of the drive mechanism 2, so as to achieve high position accuracy of the output shaft 21 and more precise adjustment of the bending angle of the bent part.

[0063] It should be noted that this embodiment does not limit the specific structure and detection principle of the position sensor 26, as long as the position sensor 26 can detect the position of the lead screw nut 24. In some embodiments, the position sensor 26 is an absolute position sensor 26, that is, the position sensor 26 is used to obtain the absolute position of the lead screw nut 24, and will not lose the position information of the lead screw nut 24 after power failure, without the need for zeroing. In addition, in some embodiments, the position sensor 26 is a linear capacitive grating sensor. Linear capacitive grating sensors have a simple structure, low power consumption, and high resolution.

[0064] In addition, in some embodiments, the drive mechanism 2 is a miniature servo electric cylinder with shafts at both ends. The miniature servo electric cylinder is small in size, high in precision, and has a high power density, and can achieve servo control with precision at any position within the stroke range.

[0065] Furthermore, to facilitate the fixing of the drive mechanism 2 and the operating unit body 1, such as... Figure 4 As shown, in some embodiments, the endoscope operating unit further includes a fixing seat 27, which is fixed to the operating unit body 1. For example, the fixing seat 27 is fixedly connected to the operating unit body 1 by a first fastener. The drive mechanism 2 is installed on the fixing seat 27. For example, the drive mechanism 2 is connected to the fixing seat 27 by a second fastener 28, thereby realizing the fixation of the drive mechanism 2 on the operating unit body 1.

[0066] In addition, the above embodiments do not limit the connection method between the output shaft 21 and the traction member 3, as long as the connection between the output shaft 21 and the traction member 3 can be achieved.

[0067] Please continue to refer to this. Figure 4 In some embodiments, the output shaft 21 is connected to the traction member 3 via a first fixing member 7. It is understood that the first fixing member 7 is provided with connection interfaces for connecting the output shaft 21 and the traction member 3. The connection between the output shaft 21 and the traction member 3 is achieved by connecting the output shaft 21 and the traction member 3 to the first fixing member 7, making the connection convenient and easy to implement. This embodiment does not limit the specific structure of the first fixing member 7, as long as it can be connected to both the output shaft 21 and the traction member 3.

[0068] In addition, to facilitate adjustment of the bending angle in all four directions (up, down, left, and right) of the curved section, please combine... Figure 4 , Figure 6 and Figure 7 In some embodiments, there are two drive mechanisms 2, which are stacked along a first direction. The output shafts 21 at the same end of the two drive mechanisms 2 are staggered along a second direction, which is perpendicular to the first direction. Both the first and second directions are perpendicular to the axial direction of the output shafts 21.

[0069] It is understandable that if a single drive mechanism 2 has two output shafts 21, then two drive mechanisms 2 have four output shafts 21, and the four output shafts 21 are respectively connected to the traction member 3, such as... Figure 4 As shown, the traction members 3 connected to the two output shafts 21 of one drive mechanism 2 are respectively called the first traction member 31 and the second traction member 32, and the traction members 3 connected to the two output shafts 21 of another drive mechanism 2 are respectively called the third traction member 33 and the fourth traction member 34. This allows for adjustment of the curved portion in four directions, with each direction being opposite to the previous one. For example, the first traction member 31 and the second traction member 32 adjust the left-right direction of the curved portion, while the third traction member 33 and the fourth traction member 34 adjust the up-down direction. Therefore, this scheme facilitates adjustment of the bending angle of the curved portion in all four directions. Furthermore, as... Figure 6 As shown, the two drive mechanisms 2 are stacked along the first direction, resulting in a compact structural layout. Figure 4 and Figure 7 As shown, the output shafts 21 at the same end of the two drive mechanisms 2 are staggered along the second direction, which makes it convenient for the output shafts 21 at the same end of the two drive mechanisms 2 to be connected to the corresponding traction components 3 respectively, and the structural layout is more reasonable.

[0070] Of course, in other embodiments, the number of drive mechanisms 2 can also be other numbers. For example, the number of drive mechanisms 2 can be one or at least three, depending on the number of bending directions required by the bending part.

[0071] Additionally, when the orientation of the output shaft 21 is opposite to the direction of the bent portion, in order to facilitate the smooth movement of the traction member 3, such as... Figure 4 As shown, in some embodiments, the operating part body 1 is provided with a fixed pulley 6, which is located at one end of the drive mechanism 2, and the traction member 3, which is located at the same end of the drive mechanism 2 as the fixed pulley 6, is wound around the fixed pulley 6.

[0072] In other words, this embodiment uses a fixed pulley 6 to guide and change the direction of the traction member 3, making it easier for the traction member 3 to connect with the output shaft 21 and the curved part respectively, while ensuring that the movement of the traction member 3 is smoother.

[0073] It should be noted that this embodiment does not limit the installation method of the fixed pulley 6, as long as the installation of the fixed pulley 6 can be achieved. For example... Figure 4 and Figure 6As shown, in some embodiments, the endoscope operating unit further includes a rotating shaft fixing plate 61 connected to the operating unit body 1 and a rotating shaft 62 connected to the rotating shaft fixing plate 61. At least one fixed pulley 6 is rotatably sleeved on the rotating shaft 62, and the rotating shaft 62 is connected to a shaft retaining ring 63 to axially limit the fixed pulley 6. It is understood that the number of fixed pulleys 6 is the same as the number of output shafts 21 whose orientation and bending portion are not on the same side, so as to realize the reversal of the traction member 3 through the fixed pulleys 6. In addition, when the number of fixed pulleys 6 is at least two, two or more fixed pulleys 6 are installed on the same rotating shaft 62, which can save installation parts and make the structure more compact.

[0074] Furthermore, in some embodiments, the traction member 3 includes a first traction segment and a second traction segment, which are connected by a second fixing member. The first traction segment is wound around the fixed pulley 6, and its diameter is larger than that of the second traction segment. That is, the traction member 3 includes a first traction segment and a second traction segment with different diameters, such that the diameter of the first traction segment wound around the fixed pulley 6 is larger than the diameter of the second traction segment not wound around the fixed pulley 6. In other words, the portion of the traction member 3 wound around the fixed pulley 6 (i.e., the first traction segment) is thicker. This makes the strength of the first traction segment greater than that of the second traction segment. During use, the first traction segment continuously rotates around the fixed pulley 6, which can reduce wear on the first traction segment and extend its service life. It should be noted that the specific structure of the second fixing member is not limited in this embodiment, as long as it can achieve the connection of the first traction segment and the second traction segment with different diameters. Of course, in other embodiments, the first traction segment and the second traction segment with different diameters can also be an integral structure or fixedly connected together by other means (such as heat fusion).

[0075] In addition, to prevent the drive mechanism 2 from self-locking and the bent part from being in a non-free state in the event of a malfunction in the drive mechanism 2 or the controller 5, such as... Figure 8 and Figure 9 As shown, in some embodiments, the operating unit body 1 is provided with an emergency window 111, and the emergency window 111 is provided with a removable emergency cover 112. The emergency window 111 corresponds to the traction member 3 so that the traction member 3 can be cut through the emergency window 111.

[0076] In other words, this embodiment has an emergency window 111 on the main body 1 of the operating unit. Under normal circumstances, the emergency cover 112 is placed on the emergency window 111 to close it. However, in abnormal circumstances, that is, when the drive mechanism 2 or the controller 5 malfunctions, the drive mechanism 2 locks itself, causing the curved part to be in a non-free state. If the above situation occurs during the examination of the patient, the insertion part of the endoscope will not be able to be smoothly removed from the patient's body. At this time, the operator can open the emergency cover 112 and cut the traction member 3 at the emergency window 111 in time, thereby releasing the tension of the traction member 3 on the curved part, so that the curved part is in a free state, making it convenient to remove the insertion part from the patient's body in time.

[0077] It is evident that this endoscope operating unit not only provides operators with a convenient, fast, and comfortable operating experience, but also enables emergency handling in case of failure of the drive mechanism 2 or controller 5, making the endoscope operating unit safe and reliable while efficiently and accurately adjusting the bending angle of the bending section.

[0078] It should be noted that this embodiment does not limit the specific method of detaching the emergency cover 112, as long as it allows for detachable installation of the emergency cover 112. For example... Figure 8 and Figure 9 As shown, in some embodiments, the emergency cover 112 is connected to the operating unit body 1 by a hand-tightening screw 113. That is, when disassembling the emergency cover 112, it is only necessary to manually unscrew the hand-tightening screw 113, which is simple to operate.

[0079] It is understandable that, such as Figure 9 and Figure 10 As shown, there is always a traction component 3 at the emergency window 111, and there are no other structural components obstructing it, so that the traction component 3 can be cut.

[0080] In addition, this embodiment does not limit the specific number of emergency windows 111. For example, there may be one emergency window 111 or at least two, as long as the emergency windows 111 can cover all the traction components 3. That is, the number of emergency windows 111 must ensure that all traction components 3 can be cut off in an emergency.

[0081] In addition, such as Figure 1 As shown, in order to facilitate maintenance of the drive mechanism 2, controller 5 and traction component 3, in some embodiments, the operating unit body 1 includes a bottom shell 11 and an upper cover 12, the upper cover 12 and the bottom shell 11 are detachably connected, the drive mechanism 2 and controller 5 are both located on the bottom shell 11; the rocker assembly 4 is located on the upper cover 12.

[0082] In other words, by removing the top cover 12, the drive mechanism 2 and controller 5 can be exposed, which facilitates the disassembly, replacement and other maintenance of the drive mechanism 2, controller 5 and the cut-off traction component 3, thereby improving the convenience of after-sales maintenance.

[0083] Furthermore, in some embodiments, the upper cover 12 and the bottom shell 11, as well as the rocker arm cap 41 and the upper cover 12, are sealed together. That is to say, the endoscope operating unit provided in the above embodiments only needs to be sealed at the connection between the bottom shell 11 and the upper cover 12, and at the connection between the rocker arm assembly 4 and the upper cover 12. Compared with the traditional manual knob and mechanical transmission mechanism used in related technologies to drive the movement of the traction member 3, the waterproof structure of the endoscope operating unit is greatly simplified.

[0084] It should be noted that this embodiment does not limit the specific sealing method of the bottom shell 11 and the top cover 12, as well as the rocker assembly 4 and the top cover 12, as long as the sealing connection of the bottom shell 11 and the top cover 12, as well as the rocker assembly 4 and the top cover 12 can be achieved.

[0085] In some embodiments, a sealing element is provided at the connection between the bottom shell 11 and the top cover 12 to achieve a sealed connection between the bottom shell 11 and the top cover 12.

[0086] In other embodiments, the rocker cap 41 is in contact with or bonded to the upper cover 12, and the rocker cap 41 is pressed against the upper cover 12 by a clamping member, thereby achieving a sealed connection between the rocker cap 41 and the upper cover 12.

[0087] Please refer to Figure 11 In addition to the endoscope operating part mentioned above, this utility model also provides an endoscope including the endoscope operating part 10 disclosed in the above embodiments. For the structure of other parts of the endoscope, please refer to the prior art, which will not be repeated here.

[0088] The key point of this embodiment is that the endoscope includes the endoscope operating part disclosed in any of the above embodiments, and has the same beneficial effects as the endoscope operating part described above, which will not be repeated here.

[0089] like Figure 11 As shown, in some embodiments, the endoscope further includes an insertion portion 20 and a light guide portion 30, the insertion portion 20 including a curved portion.
