Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a forceps elevator control device and an endoscope. Background Art

[0002] An endoscope primarily consists of a connection unit, an operating unit, and an insertion unit. For example, in an ultrasound endoscope equipped with a forceps elevator, the user simply turns a knob on the operating unit to control the direction in which the instrument extends from the forceps opening, placing it in an ideal position within the endoscope's field of view, facilitating endoscopic diagnosis and treatment procedures.

[0003] Specifically, the knob is connected to the forceps lifter through a crank slider mechanism and an operating wire. When the user rotates the knob, the operating wire can be driven to move back and forth, thereby achieving the lifting or flattening of the forceps lifter.

[0004] However, the existing crank slider mechanism is usually provided with a slider and a slide rail. The slider is connected to the operating wire of the forceps lifter and moves along the slide rail. This design needs to ensure the extension length of the slide rail, so it takes up more space, which makes it difficult to further reduce the overall size of the forceps lifter control device. For modern medical equipment that pursues compactness and lightness, this is an urgent problem to be solved. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the slide rail length of the existing forceps lifter control device is relatively long, which makes it difficult to further reduce the size of the forceps lifter control device, thereby providing a forceps lifter control device and an endoscope.

[0023] Furthermore, the mounting seat includes a main body and an ear plate; the ear plate is connected to the bottom of the main body, and a plug hole is provided on the ear plate. On a projection surface perpendicular to the axis of the main body, the plug hole is located outside the main body, and a fixing part can pass through the plug hole and different positions on the limit block to fix the limit block to the ear plate.

[0024] Furthermore, the mounting seat also includes an extension plate, a first end of the extension plate is connected to the main body, and a second end is connected to the ear plate. In the radial direction of the main body, the second end of the extension plate protrudes from the main body.

Compared with the prior art in which the operating wire is moved forward and backward along the sleeve by relying on the cooperation of the slider and the longer slide rail, the forceps lifting device control device can be smaller in size and more compact in structure, and can better meet the requirements of modern medical equipment for being small and light.

[0028] 2. The control device for the lifting forceps provided by the present invention has a guide column protruding from the second end of the connecting rod toward the swinging mechanism, a guide hole is provided on the swinging mechanism, and the guide column is slidably installed in the guide hole; or, a guide hole is provided on the second end of the connecting rod, and the swinging mechanism has a guide column protruding toward the second end of the connecting rod, and the guide column is slidably installed in the guide hole. In this way, the sliding between the connecting rod and the swinging mechanism can be made smoother, and ultimately the forward and backward movement of the operating wire along the sleeve can be made smoother.

[0029] 3. The control device for the lifting forceps provided by the present invention has a supporting curved surface protruding from one side of the swing mechanism toward the sleeve, which is suitable for supporting the sleeve and the operating wire to prevent the sleeve and the operating wire from bending due to a small curvature radius, thereby preventing the sleeve and the operating wire from causing excessive friction or damage between the sleeve and the operating wire, thereby ultimately ensuring the smooth movement of the operating wire back and forth along the sleeve.

[0030] 4. The clamp lifter control device provided by the present invention also includes a first limiting structure and a second limiting structure; the first limiting structure limits the crank to a first limit position, and the second limiting structure limits the crank to a second limit position. The first limit position is different from the second limit position. In this way, it can effectively avoid damage to the clamp lifter, operating wire, sleeve and other structures due to exceeding the movement range of the clamp lifter, which not only improves safety, but also extends the life of the clamp lifter control device and the clamp lifter.

[0031] 5. The clamp lifter control device provided by the present invention has a clearance groove on the mounting seat, and the crank part protrudes into the clearance groove. The first limiting structure is a limiting surface on the side wall of the clearance groove.

On a projection surface perpendicular to the axis of the main body, the plug hole is located outside the main body, and a fixing part can pass through the plug hole and different positions on the limit block to fix the limit block to the ear plate. In this way, on the one hand, the main body will not interfere with the fixing part, thereby facilitating the fixed connection between the limit block and the ear plate; on the other hand, while ensuring that the limit block has multiple connection positions, the weight of the mounting base can be reduced, thereby reducing the discomfort caused by the user operating the endoscope for a long time.

[0034] 8. The control device for the lifting clamp provided by the present invention, the mounting seat also includes an extension plate, the first end of the extension plate is connected to the main body, and the second end is connected to the ear plate, and the second end of the extension plate protrudes from the main body in the radial direction of the main body.

[0045] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] like Figures 1 to 4 As shown, the present invention provides an endoscope, comprising an operating portion, a connecting portion, and an insertion portion connected in sequence. The operating portion is connected to the insertion portion and is used to control the insertion portion. The operating portion is provided with a forceps lifter control device. The end of the insertion portion is provided with a forceps lifter, and an operating wire 6 in the forceps lifter control device is connected to the forceps lifter. The endoscope can be an electronic endoscope (including an upper gastrointestinal tract endoscope, a lower gastrointestinal tract endoscope), an ultrasonic endoscope, an ultrasonic bronchoscope, or other endoscopic products.

[0050] The forceps lifting device control device includes a mounting base 1, a knob 2, a crank 3, a connecting rod 4, a swing mechanism 5, an operating wire 6, a sleeve 7, and a limit block 8. The crank 3, the connecting rod 4, the swing mechanism 5, the operating wire 6, the sleeve 7, and the limit block 8 are located on the same side of the mounting base 1.

[0051] Knob 2 is rotatably mounted on mounting base 1 and protrudes from the operating unit housing for easy manual operation. Specifically, the rotating shaft of knob 2 passes through the other side of mounting base 1 and is fixedly connected to crank 3, serving as a driving mechanism for rotating crank 3. Of course, the driving mechanism can also be a rotary handle, a screwdriver, or a small motor.

[0052] The first end of the connecting rod 4 is hinged to the crank 3 , and the second end is connected to the swing mechanism 5 .

[0053] Swing mechanism 5 is rotatably mounted on mounting base 1. Rotation of knob 2 drives crank 3, which in turn drives swing mechanism 5 through connecting rod 4. Simultaneously, the second end of connecting rod 4 telescopes linearly relative to swing mechanism 5. A wire passageway, open at both ends, is formed within swing mechanism 5 to allow the operating wire 6 to pass through.

[0054] The sleeve 7 is a hose. One end of the sleeve 7 is fixedly connected to an end of the swing mechanism 5 away from the connecting rod 4.

[0055] One end of the operating wire 6 is fixedly connected to the second end of the connecting rod 4, and the other end passes through the wire channel and the sleeve 7 to connect to the forceps elevator (not shown). When the connecting rod 4 moves linearly relative to the swing mechanism 5, it drives the operating wire 6 to move back and forth in a straight line relative to the sleeve 7, thereby raising or lowering the forceps elevator.

[0056] In this embodiment, the second end of the connecting rod 4 protrudes toward the swing mechanism 5 to form a guide column 41 (such as Figure 4 As shown), a guide hole 51 is correspondingly provided on the swing mechanism 5 (as shown Figure 4 As shown), the guide column 41 is installed in the guide hole 51 along a straight line sliding manner, so that the sliding between the connecting rod 4 and the swing mechanism 5 is smoother, and ultimately the forward and backward movement of the operating wire 6 along the sleeve 7 is smoother.

[0057] In other embodiments, the guide hole 51 is opened on the second end of the connecting rod 4 , and the guide post 41 is provided on the swing mechanism 5 .

[0058] In this embodiment, the connecting rod 4 includes a first connecting rod 42 and a second connecting rod 43 that are fixedly connected together, and the connection position of the first connecting rod 42 and the second connecting rod 43 is adjustable to facilitate debugging and assembling the forceps lifting control device.

[0059] Specifically, the first connecting rod 42 is T-shaped, and the second connecting rod 43 is L-shaped. After the first connecting rod 42 and the second connecting rod 43 are fixed together, a U-shaped opening is formed on the side facing the crank 3. The first connecting rod 42 is provided with a first elongated hole 421 (such as Figure 2 As shown in FIG, the first elongated hole 421 extends along the length of the first connecting rod 42. The second connecting rod 43 is provided with a plurality of spaced mounting holes (not shown), and fasteners pass through the first elongated hole 421 and the mounting holes to secure the first connecting rod 42 and the second connecting rod 43 together.

[0060] In this embodiment, a support curved surface 52 (such as Figure 2(as shown). In this embodiment, the support curved surface 52 is a cylindrical surface, coaxially arranged with the rotation axis of the swing mechanism 5. In other embodiments, the support curved surface 52 may also have other shapes. The support curved surface 52 provides support for the operating wire 6 and the sleeve 7, preventing the sleeve 7 and the operating wire 6 from bending due to a small curvature radius, which could lead to excessive friction or damage between the sleeve 7 and the operating wire 6. Ultimately, this ensures smooth forward and backward movement of the operating wire 6 along the sleeve 7.

[0061] The crank 3 includes a first limit position for rotating in a first direction (clockwise in this embodiment) and a second limit position for rotating in a second direction (counterclockwise in this embodiment).

[0062] The clamp lifting device control device also includes a first limiting structure and a second limiting structure. The first limiting structure limits the crank 3 to a first limit position (the first limit position is as shown in FIG. Figure 1 and Figure 2 As shown), the second limiting structure limits the crank 3 to the second limit position (the second limit position is as shown in FIG. Figure 3 and Figure 4 As shown), the first extreme position is different from the second extreme position.

[0063] In this embodiment, a recess 11 is provided on the mounting base 1 (eg Figure 1 and Figure 3 As shown), the crank 3 partially protrudes into the clearance groove 11, and the first limiting structure is the limiting surface 13 on the side wall of the clearance groove 11 (as shown Figure 1 and Figure 3 As shown), compared with the design in which the first limiting structure protrudes from the surface of the mounting seat 1, it can save installation space to a certain extent and make the structure of the forceps lifting device control device more compact.

[0064] In this embodiment, the second limiting structure is a limiting block 8. The limiting block 8 is a long strip structure, and is independently formed from the mounting base 1. Specifically, the limiting block 8 protrudes from the surface of the mounting base 1, and one end is fixed to the mounting base 1. Figure 3 and Figure 4 As shown, the other end limits the crank 3 at the second limit position. In addition, in the length direction of the limit block 8, the connection position of the limit block 8 and the mounting seat 1 is adjustable.

[0065] Specifically, if Figure 3 and Figure 4 As shown, the mounting base 1 includes a disc-shaped main body 10 , an extension plate 12 , and an ear plate 14 .

[0066] The extension plate 12 is integrally formed with the main body 10. In other embodiments, the extension plate 12 and the main body 10 are separately formed and connected together. The thickness of the extension plate 12 is less than that of the main body 10. This helps reduce the weight of the mounting base 1 and reduces the discomfort caused by prolonged endoscope operation.

[0067] The ear plate 14 is fixedly connected to the end of the extension plate 12 away from the main body 10. The ear plate 14 and the extension plate 12 form an L-shaped structure. The provision of the extension plate 12 can increase the gap between the ear plate 14 and the main body 10 in the radial direction of the main body 10, thereby providing a larger connection position adjustment space for the limit block 8. Figure 4 From the perspective of the main body 10, the ear plate 14 extends obliquely to the upper left instead of extending to the lower left, which can reduce the radial size of the mounting base 1 in the main body 10. The ear plate 14 protrudes from the surface of the main body 10. Two spaced-apart plug-in holes (not shown) are provided on the ear plate 14. The two plug-in holes correspond to two fixing members 15. The two fixing members 15 can better fix the limit block 8 to the ear plate 14. A limit pin 141 is provided between the two plug-in holes for auxiliary limiting of the limit block 8. In the projection direction parallel to the axis of the main body 10, the plug-in hole falls outside the main body 10. In this way, the main body 10 will not interfere with the fixing member 15, thereby facilitating the fixed connection between the limit block 8 and the ear plate 14. On the other hand, it can reduce the weight of the mounting base 1 and reduce the discomfort caused by the user operating the endoscope for a long time. Of course, only one plug-in hole can be provided on the ear plate 14.

[0068] A second elongated hole 81 is formed at the bottom end of the stopper 8. The fixing member 15 (which may be a screw, pin, bolt, etc.) passes through the second elongated hole 81 and the plug hole to fix the stopper 8 to the ear plate 14. In other embodiments, the second elongated hole 81 is replaced by a plurality of bolt holes arranged at intervals.

[0069] When the connection position of the stopper 8 and the lug plate 14 needs to be adjusted, the position of the second elongated hole 81 on the stopper 8 relative to the insertion hole along the length direction of the second elongated hole 81 is simply adjusted. Once the target position of the stopper 8 is determined, the stopper 8 is fixed to the lug plate 14 again using the fixing member 15.

[0070] In other embodiments, the first limiting structure is a crank stopper protruding from the surface of the mounting seat 1; the second limiting structure is another crank stopper protruding from the surface of the mounting seat 1 with a smaller length, which can be a protruding structure such as a pin.

[0071] When assembling the forceps lifting control device, first rotate the crank 3 so that the crank 3 is against the limit surface 13 on the mounting seat 1 and the crank 3 reaches the first limit position. At this time, adjust the relative positions of the first connecting rod 42 and the second connecting rod 43 so that the relative positions of the connecting rod 4 and the swing mechanism 5, as well as the relative positions of the operating wire 6 and the sleeve 7 are appropriate, so that the forceps lifting device is in a fully lifted (or flat) state. At this time, fix the first connecting rod 42 and the second connecting rod 43; then rotate the crank 3 in the opposite direction so that the crank 3 is away from the limit surface 13 until the forceps lifting device is in a completely flat (or lifted) state and the crank 3 reaches the second limit position. At this time, adjust the position of the connection between the limit block 8 and the mounting seat 1 so that the limit block 8 is against the crank 3. At this time, fix the limit block 8 to the mounting seat 1 to complete the adjustment and assembly of the forceps lifting control device.

[0072] The forceps lifting control device of the present invention has a connecting rod 4 that can perform telescopic movement in a straight line relative to the swinging mechanism 5. In this way, the rotation of the knob 2 and the crank 3 can be converted into a straight line forward and backward movement of the operating wire 6 connected to the connecting rod 4 relative to the sleeve 7. Compared with the prior art in which the rotation of the knob 2 is converted into a straight line forward and backward movement of the operating wire 6 relative to the sleeve 7 by means of the cooperation of the slider and the longer slide rail, the space required for the forceps lifting control device is significantly reduced, the structure is more compact, and it can better meet the requirements of modern medical equipment for being small and light.

[0073] The forceps lifter control device in the present invention is equipped with a first limiting structure and a second limiting structure, which can effectively prevent damage to the forceps lifter, operating wire 6, sleeve 7 and other structures due to exceeding the movement range of the forceps lifter, which not only improves safety, but also extends the life of the forceps lifter control device and the forceps lifter.

[0074] The connecting rod 4 in the clamp lifter control device of the present invention is designed to be a split first connecting rod 42 and a second connecting rod 43, and the limit block 8 and the mounting seat 1 are also assembled together after being separately formed. Such a design is conducive to debugging the clamp lifter control device, so that the clamp lifter control device can perform precise limit adjustment according to the stroke of each clamp lifter, and the adaptability performance is greatly improved.

[0075] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
