Description

Technical Field

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

[0002] Endoscopes, a vital tool in modern medicine, are widely used in various examinations and surgical procedures. They penetrate the body through natural orifices or tiny incisions, enabling various examinations and minimally invasive procedures. Endoscopes consist of an operating unit and an insertion unit. The latter, which penetrates the body, uses its camera system to capture images, providing doctors with clear and accurate visual information.

[0003] In addition, some endoscopes are equipped with a forceps elevator, which can change the direction of diagnostic and treatment instruments inserted through the forceps channel, such as biopsy forceps, lithotripsy baskets, and incisors. Taking an ultrasound endoscope equipped with a forceps elevator as an example, during operation, the doctor only needs to turn the forceps elevator knob on the operating part to control the direction of the diagnostic and treatment instrument extending from the forceps channel, so that it appears accurately in the ideal position in the endoscope's field of view, greatly facilitating endoscopic diagnosis and treatment.

[0004] Currently, the forceps elevator knob is connected to the forceps elevator via an operating wire, which is enclosed by a cannula fixed to the insertion portion. Rotating the forceps elevator knob causes the operating wire to move back and forth within the cannula, generating pulling and pushing forces to raise or lower the forceps elevator. However, when the operating wire is moved by the forceps elevator knob, accurate control of the forceps elevator cannot be achieved, resulting in the inability of the forceps elevator to accurately perform the lifting operation. Summary of the Invention

[0046] Understandably, when operating an endoscope's forceps elevator, the operator typically rotates the elevator knob, causing the operating wire to move back and forth within the cannula, generating tension and thrust, thereby raising or lowering the forceps elevator. However, current methods of operating the operating wire, driven by the elevator knob, do not allow for accurate control of the forceps elevator, resulting in the inability to accurately perform the lifting operation.

[0047] To this end, the present application provides a clamp lifting device control device 100, such as Figures 1 to 3 shown. Figure 1 This is a schematic diagram of a forceps lifting device control device 100 according to an embodiment of the present application, viewed from one angle. Figure 2 for Figure 1 The exploded view of the forceps lifting device control device 100 is shown. Figure 3 for Figure 1The schematic diagram of the forceps elevator control device 100 shown is viewed from another angle. The forceps elevator control device 100 is applied to the operating portion of an endoscope. The forceps elevator control device 100 can stably output linear motion to achieve accurate control of the forceps elevator. At the same time, the overall structure is compact in size, which is conducive to the miniaturization design of the operating portion.

[0048] To better illustrate the specific structure of the forceps elevator control device 100, we will first briefly introduce the structure of the endoscope. In this application, the endoscope includes an operating portion and an insertion portion. The operating portion is connected to the proximal end of the insertion portion. The insertion portion includes at least a forceps elevator, which is located at the distal end of the insertion portion. The operating portion includes an operating handle and the forceps elevator control device 100 in this application. The forceps elevator control device 100 is located on the operating handle and can be connected to the forceps elevator to control its movement.

[0049] After the distal end of the insertion portion enters the patient's body, it can move along the human body cavity so that the distal end of the insertion portion reaches the lesion site. When a forceps elevator is needed during surgery, the doctor operates the forceps elevator control device 100, and then the forceps elevator control device 100 can control the movement of the forceps elevator so that the forceps elevator can be raised or lowered. At the same time, the forceps elevator control device 100 can also control the angle at which the forceps elevator is raised so that the forceps elevator can meet the surgical requirements after being raised.

[0050] It should be noted that this application only describes the structure of the forceps elevator control device 100, and other parts of the endoscope are not shown. The proximal end of the insertion portion refers to the end of the insertion portion that is closer to the doctor and away from the patient, and the distal end refers to the end of the insertion portion that is away from the doctor and closer to the patient. The direction of the line connecting the proximal and distal ends is the axial direction, and this proximal and distal end also apply to other components of the endoscope, which will not be described in detail later. The following describes the structure of the forceps elevator control device 100 of one embodiment.

[0051] See also Figures 1 to 3 In one embodiment, the forceps lifter control device 100 includes a screwing mechanism 110, a rotating mechanism 120, and a sliding mechanism 130. The rotating mechanism 120 includes a rotating component 121 and an output component 122. The rotating component 121 is provided on the screwing mechanism 110 and can rotate with the screwing mechanism 110. The output component 122 is movably provided on the rotating component 121. The sliding mechanism 130 is connected to the output component 122 at its proximal end and to the forceps lifter at its distal end. The sliding mechanism 130 can output linear motion along with the output component 122. The screwing mechanism 110 drives the rotating component 121 to rotate. When the rotating component 121 rotates, it can drive the output component 122 to move, so that the output component 122 drives the sliding mechanism 130 to drive the forceps lifter to move.

[0052] The screwing mechanism 110 is the operating drive member of the forceps lifter control device 100. The screwing mechanism 110 is located at the proximal end of the rotating mechanism 120 and is connected to the rotating mechanism 120. The rotating mechanism 120 can rotate synchronously with the screwing mechanism 110, and the rotating mechanism 120 can output corresponding motion. The output end of the rotating mechanism 120 is connected to the sliding mechanism 130, and the sliding mechanism 130 is also connected to the forceps lifter. The sliding mechanism 130 is arranged along the direction of the line connecting the proximal end and the distal end. In this way, the sliding mechanism 130 can output linear motion along the direction of the line connecting the proximal end and the distal end, thereby controlling the movement of the forceps lifter at the distal end. When the rotating mechanism 120 rotates, it can drive the sliding mechanism 130 to output linear motion, thereby enabling the sliding mechanism 130 to control the movement of the forceps lifter so that the forceps lifter is lifted or flattened.

[0053] Specifically, the rotating mechanism 120 includes a rotating component 121 and an output component 122. The rotating component 121 is disposed on the screwing mechanism 110 and can rotate synchronously with the screwing mechanism 110. The output component 122 is movably disposed on the rotating component 121 and is further connected to the sliding mechanism 130. Because the sliding mechanism 130 can only output sliding motion, when the screwing mechanism 110 drives the rotating component 121 to rotate, the sliding mechanism 130 can limit the rotation of the output component 122, so that the output component 122 can only perform linear motion. In addition, when the output component 122 performs linear motion, it can drive the forceps lifter to move. Here, the forceps lifter movement refers to raising or lowering the forceps lifter.

[0054] In this application, Figure 1 The up, down, left, right, clockwise and counterclockwise directions shown in FIG. 1 illustrate the movement of the sliding mechanism 130 and the rotating mechanism 120. The rotating member 121 can rotate clockwise or counterclockwise around the central axis along with the screwing mechanism 110. Figure 1 As shown, the sliding mechanism 130 can be Figure 1 The sliding mechanism 130 performs linear motion (movement) in the left and right directions as shown, thereby driving the forceps lifter to move. When the sliding mechanism 130 outputs linear motion to the right, it can generate a pulling force to drive the forceps lifter to perform a lifting action. When the sliding mechanism 130 outputs linear motion to the left, it can generate a thrust to drive the forceps lifter to perform a flattening action.

[0055] like Figure 1 As shown, when the rotating component 121 rotates in a clockwise or counterclockwise direction, it can drive the output component 122 thereon to move synchronously, but the output component 122 is connected to the sliding mechanism 130, and the sliding mechanism 130 can only output movement along the left and right directions. Therefore, when the rotating component 121 rotates, the output component 122 can only make linear motion along the left and right directions in the same straight line direction, so as to drive the sliding mechanism 130 to make linear motion along the left and right directions, so that the sliding mechanism 130 controls the action of the forceps lifter.

[0056] Moreover, when the screwing mechanism 110 is in the initial position, the forceps lifter is flat, and at this time, the output component 122 is located at the extreme position on the left side of the rotating component 121. Figure 1 When rotating in the counterclockwise direction shown, the rotating component 121 can drive the output component 122 to move linearly to the right, and then the output component 122 can drive the sliding mechanism 130 to move linearly to the right to drive the lifting forceps to perform the lifting action. Figure 1 When rotating in the clockwise direction as shown, the rotating component 121 can drive the output component 122 to move linearly to the left, and then the output component 122 can drive the sliding mechanism 130 to move linearly to the left to drive the forceps lifter to perform a flattening action.

[0057] When the forceps lifter control device 100 of the present application is used to control the forceps lifter to perform the lifting action, the doctor follows Figure 1 The screwing mechanism 110 is turned upward to the left in the direction shown. At this time, the screwing mechanism 110 can drive the rotating component 121 to rotate in the direction shown. Figure 1 When the rotating part 121 rotates counterclockwise as shown, it can drive the output part 122 to move. In addition, the position limit of the sliding mechanism 130 enables the output part 122 to drive the sliding mechanism 130 to move linearly to the right, and then the sliding mechanism 130 controls the forceps lifting device to perform the forceps lifting action. Conversely, when the screwing mechanism 110 is pushed down to the right, the screwing mechanism 110 drives the rotating part 121 to move in a straight line. Figure 1 If the rotation direction is clockwise, the rotating component 121 can drive the sliding mechanism 130 to move linearly to the left through the output component 122 to control the forceps lifting device to be leveled.

[0058] The forceps lifter control device 100 of the above embodiment uses a rotating component 121 and an output component 122 to transmit and connect the screwing mechanism 110 and the sliding mechanism 130, so as to convert the rotational motion of the screwing mechanism 110 into linear motion, so that the sliding mechanism 130 can stably output linear motion and thus control the movement of the forceps lifter, thereby achieving accurate control of the forceps lifter and meeting the operational needs of medical personnel. At the same time, the screwing mechanism 110 cooperates with the rotating component 121 and the output component 122 to cause the sliding mechanism 130 to output linear motion to control the movement of the forceps lifter, which can make the overall structural size of the forceps lifter control device 100 compact, which is conducive to the miniaturization design of the operating part.

[0059] See also Figure 2In one embodiment, the screwing mechanism 110 includes a knob housing 111, a forceps lifting knob 112, and a connecting shaft 113. The forceps lifting knob 112 is connected to the connecting shaft 113. The knob housing 111 is provided to cover the forceps lifting knob 112 and can drive the forceps lifting knob 112 to drive the connecting shaft 113 to rotate axially. The connecting shaft 113 is also connected to the rotating component 121. The connecting shaft 113 is the rotating shaft of the screwing mechanism 110. The connecting shaft 113 extends axially and is connected to the rotating component 121. The knob housing 111 is the operating housing of the screwing mechanism 110. The forceps lifting knob 112 is disposed in the knob housing 111 and is fixed to the connecting shaft 113.

[0060] When the doctor operates the knob housing 111, the knob housing 111 drives the connecting shaft 113 to rotate via the forceps lifting knob 112, which in turn drives the rotating component 121 to rotate. It is worth noting that the structural form of the knob housing 111 is generally not limited, as long as the knob housing 111 facilitates the doctor's operation. Optionally, the knob housing 111 has a protrusion to facilitate the doctor's grip.

[0061] See also Figures 1 to 3 In one embodiment, the forceps lifting device control device 100 also includes a forceps lifting frame 140, the screwing mechanism 110 is arranged on the first surface 141 of the forceps lifting frame 140, the rotating component 121 and the sliding mechanism 130 are arranged on the second surface 142 of the forceps lifting frame 140, and the connecting shaft 113 of the screwing mechanism 110 can rotatably pass through the forceps lifting frame 140 to connect to the rotating component 121.

[0062] In this embodiment, the forceps lifting frame 140 serves as a support, supporting the various components of the forceps lifting device control device 100. The forceps lifting frame 140 is also fixedly mounted to the operating handle. Of course, in other embodiments of the present application, the operating housing of the operating portion can also be used to support the various components of the forceps lifting device control device 100. This application only uses the forceps lifting frame 140 to support the various components of the forceps lifting device control device 100 as an example for description.

[0063] The forceps lifting frame 140 has a first surface 141 and a second surface 142 that oppose each other. The screwing mechanism 110 is rotatably mounted on the first surface 141 of the forceps lifting frame 140, and the rotating component 121 is rotatably mounted on the second surface 142 of the forceps lifting frame 140. The connecting shaft 113 of the screwing mechanism 110 passes through the forceps lifting frame 140 and is connected to the rotating component 121, thereby driving the rotating component 121 to rotate relative to the forceps lifting frame 140. The sliding mechanism 130 is slidably mounted on the second surface 142 of the forceps lifting frame 140 and is disposed on the same side as the rotating component 121. When the rotating component 121 rotates, the sliding mechanism 130 is driven by the output component 122 to perform linear motion relative to the forceps lifting frame 140.

[0064] For example, the forceps lifting frame 140 is disc-shaped. Optionally, the edge of the forceps lifting frame 140 has a fixing hole, through which a screw or the like passes to secure the forceps lifting frame 140 to the operating housing. Of course, in other embodiments of the present application, the forceps lifting frame 140 can also be plate-shaped or in other shapes, as long as it can support the various components of the forceps lifting device control device 100.

[0065] It is worth noting that the structural form of the rotating component 121 is not limited in principle, as long as it can convert the rotation of the screwing mechanism 110 into the linear motion of the driving output component 122. Figures 1 to 3 In one embodiment, the rotating component 121 is a connecting rod. That is, the rotating component 121 is a connecting rod structure, and the motion of the screwing mechanism 110 is transmitted to the output component 122 via the rotating component 121 in the form of a connecting rod structure. Of course, in other embodiments of the present application, the rotating component 121 may also be fan-shaped, plate-shaped, or other components capable of converting the rotational motion of the screwing mechanism 110 into linear motion of the output component 122.

[0066] See also Figures 1 to 5 In one embodiment, the rotating component 121 has an arc-shaped rotating groove 1211 , and the output component 122 is movably disposed in the rotating groove 1211 . Figure 4 for Figure 2 The partial cross-sectional view of the forceps lifting control device 100 is shown in the initial position. Figure 5 for Figure 2 The output component 122 is located behind the arc-shaped rotation groove 1211. When the rotation component 121 rotates, it can push the output component 122 to move synchronously through the inner wall of the rotation groove 1211, so that the output component 122 can drive the sliding mechanism 130 to move linearly.

[0067] When the forceps lifting device control device 100 is in the initial position, Figure 4 As shown, the rotating component 121 is located at the bottom, and the output component 122 is located at the leftmost end of the rotating groove 1211. Figure 5 As shown, the forceps lifting device control device 100 performs the forceps lifting action, the rotating component 121 rotates clockwise to the top, and the rotating component 121 slides along the output component 122 through the rotating slot 1211, so that the output component 122 is located at the rightmost end of the rotating slot 1211.

[0068] Optionally, the radius of the rotating groove 1211 gradually increases along the direction in which the rotating component 121 drives the sliding mechanism 130 to perform the pliers lifting action. Figure 1Thus, when the rotating member 121 rotates counterclockwise, the inner wall of the rotating groove 1211 can gradually push the output member 122 to move linearly to the right, causing the sliding mechanism 130 to move to the right.

[0069] Moreover, when the rotating component 121 rotates counterclockwise to move the output component 122 from one end of the rotating groove 1211 to the other end, the output component 122 can drive the sliding mechanism 130 to move to the right to the extreme position, that is, the forceps lifter is lifted to the extreme position, that is, the movement stroke of the output component 122 in the rotating groove 1211 corresponds to the linear movement stroke of the sliding mechanism 130, so as to ensure the accuracy of the forceps lifting control.

[0070] Optionally, the rotation groove 1211 extends through the rotating component 121 along the axial direction of the connecting shaft 113. This ensures the stability of the output component 122 as it moves along the rotation groove 1211. Of course, in other embodiments of the present application, the rotation groove 1211 may also be a blind groove. That is, the dimension of the rotation groove 1211 along the connecting shaft 113 is smaller than the dimension of the rotating component 121 along the connecting shaft 113.

[0071] See also Figures 1 to 6 In one embodiment, the rotating component 121 includes a connecting body 1212 and a rotating body 1213. One end of the connecting body 1212 is disposed on the screwing mechanism 110, and the other end of the connecting body 1212 is connected to the rotating body 1213. The connecting body 1212 can drive the rotating body 1213 to rotate along with the screwing mechanism 110, and the rotating groove 1211 is disposed on the rotating body 1213. Figure 6 for Figure 1 FIG. 1 is a schematic diagram of a rotating component 121 in a forceps lifting control device 100 .

[0072] One end of the connecting body 1212 is attached to the connecting shaft 113. The connecting body 1212 extends radially. The rotating body 1213 is disposed at the end of the connecting body 1212 away from the connecting shaft 113. The rotating body 1213 is provided with an arc-shaped rotating groove 1211. Thus, the connecting body 1212 and the rotating body 1213 form a cantilevered rotating link structure. When the screwing mechanism 110 rotates, the connecting body 1212 drives the rotating body 1213 to rotate synchronously, thereby driving the sliding mechanism 130 to move linearly.

[0073] Optionally, the connecting body 1212 and the rotating body 1213 are integrally formed. This ensures the structural strength of the connection between the connecting body 1212 and the rotating body 1213, allowing the connecting body 1212 to stably drive the rotating body 1213 to rotate. Of course, in other embodiments of the present application, the connecting body 1212 and the rotating body 1213 may also be fixedly connected using screws, adhesives, or other methods, as long as the reliability of the connection between the two is guaranteed.

[0074] See also Figures 1 to 5 In one embodiment, the sliding mechanism 130 includes a push rod 131, a sliding guide rail 132, and an operating rope 133. The push rod 131 is movably mounted on the sliding guide rail 132. The push rod 131 is connected to the output component 122. The proximal end of the operating rope 133 is connected to the push rod 131, and the distal end of the operating rope 133 is connected to the forceps lifter. The push rod 131 is a component at the output end of the sliding mechanism 130, and the sliding guide rail 132 is a guide component. The push rod 131 and the sliding guide rail 132 are movably engaged, and the push rod 131 can move linearly along the sliding guide rail 132. The operating rope 133 connects the proximal end of the forceps lifter and the push rod 131.

[0075] The push rod 131 is slidably mounted on a sliding guide rail 132, which is fixed to the forceps lifting frame 140. The proximal end of the operating rope 133 is mounted in the push rod 131, and the distal end of the operating rope 133 is connected to the forceps lifting device. When the rotating component 121 rotates, the rotating groove 1211 can move along the output component 122. At the same time, due to the limiting effect of the sliding mechanism 130, the output component 122 can perform linear motion as the rotating component 121 rotates. When the output component 122 performs linear motion, it can drive the push rod 131 to perform linear motion to the right or left along the sliding guide rail 132. Then, the push rod 131 can pull or push the operating rope 133 to control the forceps lifting device to be raised or lowered.

[0076] Optionally, the operating rope 133 is a steel wire rope to achieve accurate control of the forceps lifter. Optionally, the sliding guide rail 132 has a slide groove, and the push rod 131 can be slidably disposed in the slide groove and extend through the slide groove. Of course, in other embodiments of the present application, the sliding guide rail 132 and the push rod 131 can also be in the form of a slide rail and a slider, or other structural forms that can achieve sliding fit.

[0077] See also Figure 1 、 Figure 4 and Figure 5In one embodiment, the sliding rail 132 has a movable channel 1321 extending through the sliding rail 132 in the direction of movement of the push rod 131. The distal end of the operating cable 133 extends through the movable channel 1321 to connect to the forceps lifter. In other words, the movable channel 1321 extends through the sliding rail. After the push rod 131 is mounted on the sliding rail 132, the distal end of the operating cable 133 extends through the movable channel 1321. When the push rod 131 moves linearly along the sliding rail 132, the movable channel 1321 guides the movement of the operating cable 133, further ensuring the accuracy of the forceps lifter.

[0078] Optionally, the second surface 142 of the forceps lifting frame 140 has a mounting groove 143, and the sliding guide rail 132 is at least partially located in the mounting groove 143. After the sliding guide rail 132 is installed in the mounting groove 143 of the forceps lifting frame 140, it can ensure that the sliding guide rail 132 is securely fixed to the forceps lifting frame 140. At the same time, it can also reduce the height of the sliding guide rail 132 protruding from the forceps lifting frame 140, thereby reducing the size of the forceps lifting device control device 100 along the connecting axis 113. Optionally, the sliding guide rail 132 is fixed to the forceps lifting frame 140 by screws or the like.

[0079] Optionally, the rotating mechanism 120 further includes a stopper 123, which is disposed on the connecting shaft 113 and located on the side of the rotating component 121. The stopper 123 is used to limit the axial position of the rotating component 121 in the connecting shaft 113, thereby preventing the rotating component 121 from axially separating from the connecting shaft 113. Optionally, the fixing member is a retaining spring. Of course, in other embodiments of the present application, the rotating component 121 can also be fixed to the connecting shaft 113 by means of a key connection or other means.

[0080] See also Figures 1 to 5 In one embodiment, the output component 122 includes a pusher 1221 and an adapter 1222. The pusher 1221 is movably disposed in the rotation slot 1211, and the adapter 1222 is disposed in the push rod 131. The pusher 1221 is rotatably connected to the adapter 1222. When the rotating component 121 rotates, the pusher 131 can be driven to move linearly via the pusher 1221 and the adapter 1222. When the rotating component 121 drives the pusher 1221 through the rotation slot 1211, the pusher 1221 can rotate relative to the adapter 1222 to adjust the position of the pusher 1221 relative to the adapter 1222, thereby preventing the pusher 1221 and the adapter 1222 from becoming stuck. The adapter 1222 also facilitates the connection between the pusher 1221 and the push rod 131.

[0081] Optionally, the adapter 1222 and the push rod 131 are integrally formed. This ensures a reliable connection between the adapter 1222 and the push rod 131, allowing the adapter 1222 to accurately drive the push rod 131 in linear motion relative to the sliding guide rail 132. Of course, in other embodiments of the present application, the adapter 1222 and the push rod 131 may also be fixedly connected using threads or adhesive, as long as the reliability of the connection is guaranteed. Optionally, the adapter 1222 is a mounting housing or mounting bracket, etc.

[0082] Optionally, the pushing portion 1221 is cylindrical. Thus, when the rotating member 121 moves along the pushing portion 1221 through the rotating groove 1211, the pushing portion 1221 can rotate relative to the adapter 1222, thereby reducing friction between the pushing portion 1221 and the rotating groove 1211, thereby preventing jamming and ensuring smooth rotation of the rotating member 121. Of course, in other embodiments of the present application, the pushing portion 1221 can also be spherical or have a slider structure. Optionally, the pushing portion 1221 and the adapter 1222 are rotatably connected via a hinge shaft.

[0083] See also Figures 1 to 5 In one embodiment, the forceps lifting device control device 100 further includes a limiting mechanism 150, which is provided on the second surface 142 of the forceps lifting frame 140. The limiting mechanism 150 can abut the rotating part 121 after the rotating part 121 rotates to a preset angle to limit the rotation angle of the rotating part 121. The limiting mechanism 150 is fixedly provided on the second surface 142 of the forceps lifting frame 140, and the limiting mechanism 150 extends toward the rotating part 121. When the rotating part 121 rotates to a predetermined rotation angle, the rotating part 121 can abut the limiting mechanism 150, and the rotation angle of the rotating part 121 is limited by the limiting mechanism 150 to avoid excessive rotation of the rotating part 121, thereby avoiding excessive opening of the forceps lifting device, as long as the opening angle of the forceps lifting device can meet the use requirements.

[0084] It is worth noting that the fixed position of the limiting mechanism 150 on the forceps lifting frame 140 is pre-set, the rotation angle of the rotating component 121 is pre-set, the installation position of the limiting mechanism 150 on the forceps lifting frame 140 is determined according to the rotation angle of the rotating component 121, and then the limiting mechanism 150 is fixed to the forceps lifting frame 140. For different types of forceps lifting device control devices 100, the limiting mechanism 150 can be arranged at different positions of the forceps lifting frame 140 so that the rotating component 121 has different rotation angles to meet different forceps lifting control requirements.

[0085] See also Figures 1 to 5In one embodiment, the limiting mechanism 150 includes a limiting rod 151 and a fastener 152. The limiting rod 151 has a first end and a second end opposite to each other. The fastener 152 passes through the first end of the limiting rod 151 to fix the limiting rod 151 to the forceps lifting frame 140. The second end of the limiting rod 151 extends toward the rotating component 121 to limit the rotating component 121. The limiting rod 151 is arranged in an elongated strip shape. The limiting rod 151 has a first end and a second end opposite to each other. The first end of the limiting rod 151 is fixed to the forceps lifting frame 140 by the fastener 152, and the limiting rod 151 extends toward the rotating component 121. The second end of the limiting rod 151 is aligned with the rotating component 121. When the rotating component 121 rotates to a predetermined rotation angle, the second end of the limiting rod 151 can abut the rotating component 121 to limit the rotation angle of the rotating component 121, thereby preventing the rotating component 121 from excessive rotation.

[0086] In one embodiment, the limiting rod 151 includes a mounting section and a limiting section. The limiting section is provided on the mounting section. The mounting section is detachably provided on the lifting forceps frame 140. The limiting section extends toward the rotating component 121 and abuts against the rotating component 121 after the rotating component 121 rotates a preset angle. The mounting section is the first end of the limiting rod 151. The mounting section is used to fix the mounting section on the lifting forceps frame 140. The fastener 152 passes through the mounting section and is fixedly installed to the lifting forceps frame 140. The limiting section extends toward the direction of the rotating component 121. When the rotating component 121 rotates to a predetermined rotation angle, the limiting rod 151 abuts against the rotating component 121 through the limiting section to limit the rotation angle of the rotating component 121 to prevent the rotating component 121 from rotating excessively. Optionally, the mounting section and the limiting section are an integral structure.

[0087] See also Figures 1 to 5 In one embodiment, the limiting rod 151 further has an adjustment hole 1511, through which the fastener 152 is fixed to the forceps lifting frame 140, and the limiting rod 151 can move along the fastener 152 through the adjustment hole 1511 to adjust the distance between the fastener 152 and the forceps lifting frame 140. The adjustment hole 1511 passes through the limiting rod 151, and the fastener 152 can pass through the adjustment hole 1511 and be installed to the forceps lifting frame 140 to fix the limiting rod 151 to the forceps lifting frame 140.

[0088] Moreover, after the fastener 152 is tightened, the fastener 152 can fix the limit rod 151 to the lifting clamp frame 140, and the limit rod 151 is fixed. When the fastener 152 is loosened, the limit rod 151 can move along the fastener 152 through the adjustment hole 1511, as shown in FIG. Figure 4 and Figure 5In the direction of the arrow shown, the limiting rod 151 is moved closer to or away from the rotating component 121 to adjust the distance between the limiting rod 151 and the rotating component 121, so that the rotating component 121 has different limit rotation angles.

[0089] In one embodiment, the adjustment hole 1511 is an oblong hole, an elliptical hole or a bar hole. In this way, the limiting rod 151 can pass through the adjustment hole 1511 along the fastener 152 Figure 4 and Figure 5 The adjusting hole 1511 is provided with a plurality of fasteners 152, each of which is arranged along the length of the adjusting hole 1511. In this way, the plurality of fasteners 152 can limit the position of the limiting rod 151, preventing the limiting rod 151 from rotating around the fasteners 152.

[0090] It is understandable that one end of the sliding guide rail 132 and the limiting rod 151 can be fixed to the forceps lifting frame 140, and the sliding guide rail 132 and the limiting rod 151 are supported and fixed by the forceps lifting frame 140. Of course, in another embodiment, the forceps lifting device control device 100 further includes a support frame 160, which at least partially surrounds the circumference of the forceps lifting frame 140, and the sliding guide rail 132 and the limiting rod 151 are fixed to the support frame 160.

[0091] That is, the support frame 160 is disposed outside the forceps lifting frame 140, and is used to support the forceps lifting frame 140. In addition, one end of the sliding guide rail 132 and the mounting section of the limit rod 151 are located on the support frame 160, and the sliding guide rail 132 and the limit rod 151 are supported and fixed by the support frame 160. Optionally, the support frame 160 has a recessed area for mounting the sliding guide rail 132 and the limit rod 151.

[0092] See also Figures 1 to 5 In one embodiment, the forceps lifting frame 140 has a clearance groove 144. The clearance groove 144 is recessed in the second surface 142 of the forceps lifting frame 140 and extends to the edge of the forceps lifting frame 140. The clearance groove 144 is a notch in the forceps lifting frame 140. When the forceps lifting device control device 100 is assembled with the operating part and the insertion part, the clearance groove 144 can avoid interference with other components.

[0093] The forceps lifting device control device 100 of the present application uses a rotating component 121 and an output component 122 to transmit and connect the screwing mechanism 110 and the sliding mechanism 130, so as to convert the rotational motion of the screwing mechanism 110 into the linear motion of the sliding mechanism 130, so that the sliding mechanism 130 can stably output the linear motion and thus control the movement of the forceps lifting device, thereby achieving accurate control of the forceps lifting device and meeting the operational needs of medical personnel. At the same time, the screwing mechanism 110, through the cooperation of the rotating component 121 and the output component 122, causes the sliding mechanism 130 to output the linear motion to control the movement of the forceps lifting device, which can make the overall structural size of the forceps lifting device control device 100 compact, which is conducive to the miniaturization design of the operating part.

[0094] The present application also provides an endoscope, comprising an operating portion and an insertion portion, wherein the operating portion is connected to the proximal end of the insertion portion, the operating portion at least comprises a forceps elevator control device 100 as in any of the above-mentioned embodiments, and the insertion portion at least comprises a forceps elevator, which is disposed at the distal end of the insertion portion. The forceps elevator control device 100 is disposed at the operating portion and connected to the forceps elevator, and the forceps elevator control device 100 is capable of controlling the forceps elevator to be lifted or laid flat. After the endoscope of the present application adopts the forceps elevator control device 100 of the above-mentioned embodiment, it can accurately control the forceps elevator to be lifted and laid flat to meet surgical needs.

[0095] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
