Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to an endoscope device and an endoscope. Background Art

[0002] With the advancement of science and technology, endoscopes are increasingly used in modern minimally invasive surgeries. They can be inserted into the stomach or other natural orifices through the mouth. The endoscope's tip is used to extend into the human body. By manipulating the tip in various directions, it can inspect ducts or body cavities. The tip's optical system captures images of the corresponding area, enabling observation, photography, and diagnosis.

[0003] In actual use, the endoscope mainly performs operations such as bending angles and controlling the lifting forceps by stretching the wire rope through the handle. The wire rope is constantly subjected to tensile pressure and the influence of aging, and will undergo certain plastic deformation, causing the length of the wire rope to continue to lengthen, which ultimately affects the normal operation of the endoscope.

[0004] In the related art, a patent document with the announcement number CN209377529U proposes a lifting clamp mechanism for an endoscope and an adjustable wire rope. Although the tension of the endoscope's wire rope can be adjusted based on the selective matching connection between the first adjustment groove and the plurality of second adjustment holes on the slider body, the tension of the wire rope can usually only be adjusted during the assembly process or before leaving the factory. During the use of the endoscope, if the wire rope becomes loose, the endoscope can only be returned to the factory for disassembly, and then the wire rope pre-tightening adjustment can be performed. This is not only time-consuming and labor-intensive, but also increases the user's cost of use, affecting the user experience of the endoscope. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1-6 An endoscopic device and an endoscope according to the present invention are described.

[0035] like Figure 1 and Figure 3As shown, this embodiment provides an endoscope device, including: a rotating joint 3, a movable joint 4, an adjusting component 5 and a locking structure; one end of the rotating joint 3 is used to be rotatably connected to the transmission part 2 of the endoscope; the rotating joint 3 and the movable joint 4 constitute a screw connection structure, and the end of the movable joint 4 away from the transmission part 2 is used to be connected to one end of the wire rope 13; the adjusting component 5 is used to drive the movable joint 4 to move along the axial direction of the wire rope 13; when the locking structure is in an unlocked state, the locking structure is separated from the rotating joint 3, and when the locking structure is in a locked state, the locking structure is connected to the rotating joint 3 to prevent the rotating joint 3 from rotating relative to the transmission part 2.

[0036] Specifically, this embodiment comprises a rotating joint 3, a movable joint 4, an adjustment component 5, and a locking structure. On the one hand, by operating the adjustment component 5, the relative movement of the rotating joint 3 and the movable joint 4 along the axial direction of the wire rope can be conveniently controlled. On the other hand, after the relative positions of the rotating joint 3 and the movable joint 4 are adjusted, the locking structure can be used to control the rotating joint 3 and the movable joint 4 to remain relatively stationary. In this way, the present invention can conveniently adjust the tension of the endoscope's wire rope according to usage requirements without having to return the endoscope to the factory for disassembly, thereby improving the user experience.

[0037] It should be pointed out here that this embodiment can control the state of the locking structure alone, or connect the locking structure with the adjustment component 5. When the adjustment component 5 drives the movable section 4 to move, the state of the locking structure is also controlled in linkage to improve the convenience of operation.

[0038] like Figure 1 and Figure 3 As shown, the transmission unit 2, the rotating joint 3, the movable joint 4, and the wire rope 13 shown in this embodiment are arranged in sequence along the axial direction of the wire rope 13. The transmission unit 2 is specifically an endoscope chain or an adapter provided at one end of the chain. The transmission unit 2 shown in this embodiment can be connected to one end of the rotating joint 3 via a ball joint, so that the rotating joint 3 can rotate relative to the transmission unit 2 along the central axis of the wire rope 13.

[0039] At the same time, the rotating joint 3 shown in this embodiment is cylindrical, the moving joint 4 is rod-shaped, and part of the structure of the moving joint 4 is located inside the rotating joint 3 and forms a screw connection structure with the rotating joint 3.

[0040] Specifically, the rotating joint 3 shown in this embodiment is equivalent to a screw nut, and the moving joint 4 is equivalent to a screw. The internal thread on the inner wall surface of the rotating joint 3 is connected to the external thread on the side wall of the moving joint 4 to form a screw connection structure.

[0041] In this way, when the locking structure is in the unlocked state, since the locking structure is separated from the rotating joint 3, when the adjusting component 5 drives the movable joint 4 to move along the axial direction of the wire rope, the rotating joint 3 will rotate at the original position relative to the transmission part 2 of the endoscope, and the relative position of the rotating joint 3 and the movable joint 4 along the axial direction of the wire rope will change; and when the locking structure is in the locked state, since the locking structure is connected to the rotating joint 3, the freedom of rotation of the rotating joint 3 relative to the transmission part 2 is restricted, and at this time, an axial force is applied to the movable joint 4, and the rotating joint 3 and the movable joint 4 will remain relatively stationary.

[0042] Therefore, after the relative positions of the rotating joint 3 and the moving joint 4 are adjusted, the tightness of the steel wire rope is finally adjusted based on the locking effect of the locking structure.

[0043] like Figure 1 and Figure 3 As shown, the movable joint 4 shown in this embodiment moves along the first direction, and the adjusting component 5 moves along the second direction. The first direction is distributed along the axial direction of the wire rope 13, and the first direction and the second direction form a preset angle. The movable joint 4 is provided with an action surface 10 at one end away from the transmission part 2. The end of the adjusting component 5 along the second direction has a first state separated from the action surface 10 and a second state in contact with the action surface 10.

[0044] Specifically, in order to facilitate the movement of the movable section 4 along the axial direction of the wire rope by the adjustment component 5, the first direction can be set to Figure 1 or Figure 3 The horizontal direction shown, the second direction is Figure 1 or Figure 3 The vertical direction shown is such that the angle between the first direction and the second direction is 90°. In this embodiment, the active surface 10 of the movable joint 4 can be set at an acute angle to the axial direction of the wire rope, so that when the adjustment component 5 moves in the second direction, it drives the movable joint 4 to move in the first direction. The active surface 10 can be a single plane or arc surface, or a conical surface extending along the circumference of the movable joint 4, without specific limitation.

[0045] In this way, when the adjusting component 5 is in the first state, since one end of the adjusting component 5 is separated from the active surface 10 of the moving section 4, the adjusting component 5 cannot apply a force to the moving section 4. When the adjusting component 5 moves along the second direction, one end of the adjusting component 5 can gradually contact the active surface 10 of the moving section 4, and as the adjusting component 5 continues to move, the moving section 4 can move along the first direction under the drive of the adjusting component 5.

[0046] Of course, the second direction shown in this embodiment is not limited to Figure 1 or Figure 3In the vertical direction shown, for example, in this embodiment, the adjusting component 5 can also be arranged at a certain inclination angle relative to the vertical direction. As long as it is convenient for the adjusting component 5 to apply a force to the action surface 10 of the movable section 4 to realize the solution of driving the movable section 4 to move axially along the wire rope, the design requirements are met.

[0047] like Figure 1 and Figure 3 As shown, the rotating joint 3 and the movable joint 4 shown in this embodiment are arranged in the shell 1; a mounting groove 8 is provided on the shell wall of the shell 1; the adjusting component 5 is movably arranged in the mounting groove 8 along the second direction, and the other end of the adjusting component 5 along the second direction is located in the mounting groove 8.

[0048] Here, the housing 1 shown in this embodiment is specifically the outer shell of the endoscope handle. By positioning the other end of the adjustment member 5 within the mounting groove 8, the other end of the adjustment member 5 does not protrude beyond the notch of the mounting groove 8. This prevents the operator from accidentally triggering the adjustment member 5 while operating the endoscope, thereby preventing the normal operation of the endoscope from being affected. Furthermore, the arrangement of the adjustment member 5 in this embodiment ensures a seal between the adjustment member 5 and the mounting groove 8 on the housing 1.

[0049] According to the operation mode of the adjusting component 5 , this embodiment specifically illustrates the movement control of the adjusting component 5 along the second direction in combination with the following two embodiments.

[0050] In one embodiment, Figure 1 and Figure 2 As shown, the adjusting component 5 shown in this embodiment includes a pressing component; the pressing component includes a pressing input head 511, a connecting rod 512 and a pressing action head 513; the pressing input head 511, the connecting rod 512 and the pressing action head 513 are connected in sequence; the pressing input head 511 is located in the mounting groove 8, the connecting rod 512 can movably pass through the bottom of the mounting groove 8, and the pressing action head 513 is located in the shell 1 and can contact or separate from the action surface 10.

[0051] Thus, in this embodiment, by performing a pressing operation on the pressing input head 511 of the pressing component, the pressing component can be conveniently controlled to move downward, so that the pressing action head 513 of the pressing component contacts the action surface 10 of the movable joint 4. Correspondingly, in this embodiment, by controlling the pressing input head 511 to move upward, the pressing action head 513 can be separated from the action surface 10 of the movable joint 4.

[0052] Here, in order to facilitate the automatic separation of the pressing action head 513 and the action surface 10 of the moving joint 4, this embodiment may further provide an elastic member 9 between the pressing input head 511 and the bottom of the installation groove 8. The elastic member 9 is preferably a spring.

[0053] In another embodiment, Figure 3 and Figure 4 As shown, the adjustment component 5 shown in this embodiment includes a knob component; the knob component includes a knob input head 521, a threaded rod 522 and a knob action head 523; the knob input head 521 is located in the mounting groove 8, the threaded rod 522 passes through the bottom of the mounting groove 8, and is threadedly connected to the bottom of the mounting groove 8, and the knob action head 523 is located in the shell 1 and can contact or separate from the action surface 10.

[0054] Thus, in this embodiment, by controlling the knob input head 521 to rotate in a first rotational direction, the knob component can be moved downward based on the threaded connection between the threaded rod 522 and the threaded hole at the bottom of the mounting slot 8, so that the knob action head 523 of the knob component contacts the action surface 10 of the movable section 4. Correspondingly, in this embodiment, by controlling the knob input head 521 to rotate in a second rotational direction, the knob action head 523 can be separated from the action surface 10 of the movable section 4. The first rotational direction and the second rotational direction are opposite in rotational direction.

[0055] It should be noted that in order to facilitate the application of force to the active surface 10 of the movable joint 4, the pressing head 513 of the pressing component and the knob head 523 of the knob component shown in this embodiment are preferably conical heads. Because the conical surface of the conical head can better fit the active surface 10 of the movable joint 4, the pressing component or the knob component can easily drive the movable joint 4 to move axially along the wire rope.

[0056] At the same time, in order to facilitate the control of the relative position between the rotating joint 3 and the movable joint 4, this embodiment can apply lubricating grease between the rotating joint 3 and the movable joint 4, and this embodiment can also apply lubricating grease between one end of the adjusting component 5 and the active surface 10 of the movable joint 4.

[0057] Preferably, in order to facilitate the control of the rotational freedom of the rotating joint 3 , this embodiment performs linkage control on the state of the locking structure based on the adjusting component 5 .

[0058] The locking structure shown in this embodiment is configured as a linkage arm 6 and a locking plate 7; one end of the linkage arm 6 is connected to the adjusting component 5; the other end of the linkage arm 6 is connected to the locking plate 7; a first tooth pattern is provided on the rotating joint 3, and a second tooth pattern is provided on the locking plate 7; when the adjusting component 5 is in the first state, the first tooth pattern is engaged with the second tooth pattern; when the adjusting component 5 is in the second state, the first tooth pattern is separated from the second tooth pattern.

[0059] Among them, when the rotating joint 3 is cylindrical and the moving joint 4 is rod-shaped, the first tooth pattern is circumferentially arranged on the outer wall of the rotating joint 3, the locking plate 7 extends circumferentially along the rotating joint 3, and the second tooth pattern is located on the side of the locking plate 7 facing the rotating joint 3.

[0060] like Figure 1 and Figure 2 As shown, when the adjusting component 5 is a pressing component, an opening is provided in the slot of the mounting slot 8 in this embodiment. After passing through the opening, one end of the linkage arm 6 extends into the mounting slot 8 and is located at the lower end of the pressing input head 511 of the pressing component.

[0061] Specifically, when the operator does not apply a downward pressing force to the pressing input head 511, the first tooth pattern is engaged with the second tooth pattern, so that the rotating joint 3 and the movable joint 4 cannot move relative to each other along the axial direction of the wire rope. When a downward force is applied to one end of the linkage arm 6 by the pressing input head 511, on the one hand, the first tooth pattern is separated from the second tooth pattern to release the restriction on the rotational freedom of the rotating joint 3. On the other hand, based on the downward movement of the pressing component, the pressing action head 513 of the pressing component applies the force on the action surface 10 of the movable joint 4, which can cause the movable joint 4 to shrink into the rotating joint 3 to tighten the wire rope. Accordingly, when the operator releases the pressing input head 511, based on the restoring force of the elastic component 9 shown in the above embodiment, the pressing component rises and resets, and the first tooth pattern is engaged with the second tooth pattern again to limit the rotational freedom of the rotating joint 3 and lock the relative position of the rotating joint 3 and the movable joint 4, thereby ultimately achieving the purpose of adjusting the tightness of the wire rope.

[0062] like Figure 3 and Figure 4 As shown, in the case where the adjustment component 5 is a knob component, this embodiment provides an opening at the notch of the mounting slot 8. After passing through the opening, one end of the linkage arm 6 extends into the mounting slot 8 and is located at the lower end of the knob input head 521 of the knob component. In this embodiment, an annular latch tongue can be provided at one end of the linkage arm 6, and an annular latch groove can be provided at the lower end of the knob input head 521, into which the annular latch tongue extends. In this way, linkage control can be applied to one end of the linkage arm 6 based on the knob input head 521 without affecting the rotation operation of the knob input head 521.

[0063] Specifically, when the operator does not apply a rotational driving force to the knob input head 521, the first tooth pattern is engaged with the second tooth pattern, so that the rotating section 3 and the moving section 4 cannot move relative to each other along the axial direction of the wire rope. When a rotational driving force is applied to the knob input head 521, the knob component can be controlled to move downward to apply a downward force to one end of the linkage arm 6. On the one hand, the first tooth pattern is separated from the second tooth pattern, and the restriction on the rotational freedom of the rotating section 3 is released. On the other hand, based on the downward movement of the knob component, the knob component The force applied by the knob action head 523 to the action surface 10 of the movable joint 4 can cause the movable joint 4 to retract into the rotating joint 3 to tighten the wire rope; accordingly, when the operator applies a rotational driving force in the opposite direction to the knob input head 521, the knob component can be controlled to rise and reset. Under the linkage action of the knob input head 521, the locking plate 7 rises, and the first tooth pattern and the second tooth pattern engage again to limit the rotational freedom of the rotating joint 3 and lock the relative position of the rotating joint 3 and the movable joint 4, thereby achieving the purpose of adjusting the tightness of the wire rope.

[0064] like Figure 5 As shown, this embodiment also provides an endoscope device, including: a rotating joint 3, a movable joint 4, an adjusting component 5 and a locking structure; one end of the rotating joint 3 is used to be rotatably connected to the transmission part 2 of the endoscope; the rotating joint 3 and the movable joint 4 constitute a screw connection structure, and the end of the movable joint 4 away from the transmission part 2 is used to be connected to one end of the wire rope; the adjusting component 5 is used to drive the rotating joint 3 to rotate relative to the transmission part 2, so that the movable joint 4 can move along the axial direction of the wire rope; the locking structure is provided between the adjusting component 5 and the rotating joint 3, so as to realize the locking connection between the adjusting component 5 and the rotating joint 3 when the adjusting component 5 does not receive any rotation input.

[0065] Specifically, when adjusting the tightness of the wire rope, this embodiment drives the rotating joint 3 to rotate relative to the transmission part 2 through the adjusting component 5, and can adjust the relative position of the rotating joint 3 and the movable joint 4 along the axial direction of the wire rope. After the adjustment is completed, the locking connection between the adjusting component 5 and the rotating joint 3 based on the locking structure can limit the degree of freedom of the rotating joint 3, so that the rotating joint 3 and the movable joint 4 remain relatively stationary. In this way, the present invention can conveniently adjust the tightness of the wire rope of the endoscope according to usage requirements without returning the endoscope to the factory for disassembly, thereby improving the user experience.

[0066] The locking structure shown in this embodiment may be a clutch device between the adjusting component 5 and the rotating joint 3 .

[0067] like Figure 5 and Figure 6As shown, the adjustment component 5 shown in this embodiment includes a rotating component; the rotating component is provided with a first gear structure 11, and the rotating joint 3 is provided with a second gear structure 12; the first gear structure 11 and the second gear structure 12 are meshed and form a locking structure. Among them, the first gear structure 11 and the second gear structure 12 shown in this embodiment are preferably bevel gears.

[0068] Specifically, the rotating component shown in this embodiment includes a rotating input head 531, a connecting rod 532, and a rotating actuating head 533, with a first gear structure 11 disposed on the rotating actuating head 533. The rotating input head 531, the connecting rod 532, and the rotating actuating head 533 are sequentially connected. The rotating input head 531 is positioned within the mounting slot 8 shown in the above embodiment. The connecting rod 532 rotatably passes through the bottom of the mounting slot 8. The rotating actuating head 533 is positioned within the housing 1, such that the first gear structure 11 on the rotating actuating head 533 meshes with the second gear structure 12 at the other end of the rotating joint 3.

[0069] Thus, in this embodiment, when controlling the rotation of the rotating component, the first gear structure 11 and the second gear structure 12 drive the rotating joint 3 relative to the endoscope's transmission unit 2. Because the rotating joint 3 and the movable joint 4 form a screw connection, the movable joint 4 is driven to retract into the rotating joint 3, thereby tightening the wire rope. When the rotating component is released, the self-locking function of the first gear structure 11 and the second gear structure 12 when engaged prevents the rotating joint 3 and the movable joint 4 from moving relative to each other, thereby achieving the purpose of adjusting the tension of the wire rope.

[0070] Preferably, this embodiment further provides an endoscope, comprising: a housing 1; an endoscope wire rope pre-tensioning device as described in any one of the above items is provided in the housing 1.

[0071] Specifically, since the endoscope includes the endoscope wire rope pre-tensioning device shown in the above-mentioned embodiment, the specific structure of the endoscope wire rope pre-tensioning device refers to the above-mentioned embodiment. Since the endoscope adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
