[0002] This disclosure claims priority to Chinese patent application No. 202323529236.8, filed on December 22, 2023, entitled "Endoscope", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of manipulation mechanism technology, and in particular to endoscopes. Background Technology

[0004] An endoscope is a device used to explore the inside of cavities or orifices. With the development of medical technology, flexible endoscopes are widely used for the examination and treatment of diseases in cavities or tubes that open naturally in the body.

[0005] The endoscope includes an operating handle, a bending section, a lens, a positioning mechanism, and a tubing assembly. The operating handle includes a plate-shaped component and a bending operation component disposed on the plate-shaped component. The plate-shaped component is indirectly connected to the proximal end of the bending section, the distal end of which houses the lens. The bending operation component of the operating handle is used to manipulate the bending section to adjust the lens's field of view. The tubing assembly includes a branch tubing component, a flexible tubing component, and a connecting portion. The branch tubing component is disposed on the positioning mechanism, which is connected to the plate-shaped component. The branch tubing component is connected to the flexible tubing component via the connecting portion, and the flexible tubing component is disposed on the operating handle.

[0006] The connection structure of an endoscope is complex and precise, and the assembly space is compact and small. After installation or during use, the connection between some parts of the endoscope, such as the connecting part or the plate-shaped part and the positioning mechanism, may become loose. Utility Model Content

[0007] Therefore, it is necessary to provide an endoscope to address the issue of loose connection structures.

[0008] This disclosure provides an endoscope including a manipulator, a positioning mechanism, a rigid tube component, a flexible tube component, and a connecting portion. The manipulator includes a plate-shaped component. The positioning mechanism is connected to the distal end of the plate-shaped component. The rigid tube component is positionally connected to the plate-shaped component via the positioning mechanism. The flexible tube component is disposed at the plate-shaped component. The connecting portion connects the rigid tube component and the flexible tube component, and is fixedly connected to the plate-shaped component.

[0009] In the endoscope provided in this embodiment, the connecting part is fixedly connected to the plate-shaped component, thereby enabling a firm and reliable connection between the rigid tube component and the flexible tube component, preventing the rigid tube component and the flexible tube component from loosening, leaking, or detaching due to the use of the endoscope.

[0010] In some embodiments, the connection is welded to or bonded to the plate-shaped component.

[0011] This design, using welding or bonding, increases the contact area between the connecting part and the plate-shaped component, thereby improving the strength and reliability of the connection between the connecting part and the plate-shaped component.

[0012] In some embodiments, the endoscope further includes a bending section, an insertion tube component, and a branch tube component. The proximal end of the bending section is connected to a plate-like component. The branch tube component and the rigid tube component are respectively connected to the proximal end of the insertion tube component, which is disposed in the positioning mechanism. The plate-like component has clearance space for the corresponding connection portion. The operating mechanism further includes a bending operation component, which is disposed on both sides of the plate-like component along the thickness direction, and is used to control the bending of the bending section.

[0013] With this configuration, the bending operation component achieves control on one side of the plate-shaped component along the thickness direction, effectively utilizing the limited assembly space; since the connecting part is fixed to the plate-shaped component and located on the other side of the plate-shaped component along the thickness direction, the hose is prevented from being affected by the operation of the bending operation component.

[0014] In some embodiments, the distal end of the plate-shaped member includes two mating portions. A positioning mechanism is fitted onto the two mating portions and onto the rigid tube member. A branch tube member extends from the inside of the positioning mechanism to the outside of the positioning mechanism and protrudes from the positioning mechanism. The rigid tube member penetrates the plate-shaped member along its thickness direction. The rigid tube member is located between the two mating portions.

[0015] This configuration, with the positioning mechanism connected to the branch tube assembly, facilitates the entry of instrument and fluid channels into the positioning mechanism via the branch tube assembly. The positioning mechanism is connected to the plate-shaped component via a mating part, and the rigid tube component penetrates the plate-shaped component and is located between the two mating parts, which facilitates the relative positioning of the positioning mechanism and the plate-shaped component.

[0016] In some embodiments, the distal end of the plate-shaped component includes two fitting portions that are fitted and fixedly connected to the positioning mechanism.

[0017] With this configuration, the fitting part is fixedly connected to the positioning mechanism, thereby ensuring a firm and reliable connection between the plate-shaped component and the positioning mechanism. This prevents relative movement between the plate-shaped component and the positioning mechanism due to the use of the endoscope, which could increase the control error of the bending operation component on the bending part.

[0018] In some embodiments, the plate-shaped component further includes a plate body and a wedge. The plate body has a guide groove, and the wedge is disposed in the guide groove. The bottom of the guide groove is inclined relative to the connecting portion, so that the wedge abuts against the connecting portion and the plate-shaped component.

[0019] With this configuration, the bottom of the guide groove is inclined relative to the connecting part, which helps the wedge block to tightly abut against the connecting part using the guide groove, thus increasing the connection strength between the wedge block and the connecting part.

[0020] In some embodiments, the connector is configured to be rotatably connected to a rigid tube component. The connector has a snap-fit ​​groove, at least one sidewall of which is constrained by the sidewall of a wedge.

[0021] With this configuration, the sidewall of the wedge can engage with the locking groove of the connector to lock the connector in place, preventing the rigid pipe component from loosening or detaching from the connector due to rotation.

[0022] In some embodiments, the connecting part is fixedly connected to the wedge, and the plate-shaped component is fixedly connected to the wedge.

[0023] With this configuration, the connecting part is fixedly connected to the plate-shaped component by a wedge, thereby ensuring a firm and reliable connection between the rigid tube component and the flexible tube component, preventing the rigid tube component and the flexible tube component from loosening, leaking, or coming loose due to the use of the endoscope.

[0024] This disclosure also provides an endoscope including a manipulator, a positioning mechanism, and a tubing assembly. The manipulator includes a plate-like component. The positioning mechanism is fixedly connected to the distal end of the plate-like component. The tubing assembly is positionally connected to the plate-like component via the positioning mechanism.

[0025] The endoscope provided in this embodiment includes an operating mechanism for operating the endoscope and a positioning mechanism for positioning the plate-shaped component relative to the tubing assembly.

[0026] In some embodiments, the positioning mechanism is welded to or bonded to the distal end of the plate-like component.

[0027] This configuration allows for a secure and reliable connection between the plate-shaped components and the positioning mechanism via welding or bonding, preventing them from becoming loose due to the use of the endoscope.

[0028] In some embodiments, the distal end of the plate-shaped component includes two fitting portions that are fitted and fixedly connected to the positioning mechanism.

[0029] With this configuration, the two fitting parts are fixedly connected to the positioning mechanism, thereby ensuring a firm and reliable connection between the plate-shaped component and the positioning mechanism. This prevents relative movement between the plate-shaped component and the positioning mechanism due to the use of the endoscope, which could increase the control error of the bending operation component on the bending part.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0045] refer to Figure 1 , Figure 1 The structure of an endoscope 100 according to an embodiment of this disclosure is shown. This disclosure relates to the technical field of manipulation mechanisms 1.

[0046] For the endoscope 100, the two ends of its components along the insertion direction, those facing the insertion side can be called the distal end, and those facing the operation side can be called the proximal end.

[0047] The endoscope 100 provided in this embodiment includes a manipulation mechanism 1, a positioning mechanism 2, a rigid tube component 31, a flexible tube component 32, and a connecting part 33.

[0048] The operating mechanism 1 includes a plate-shaped component 10. Exemplarily, the plate-shaped component 10 is generally rectangular in shape.

[0049] The positioning mechanism 2 is connected to the operating mechanism 1, specifically, the positioning mechanism 2 is connected to the plate-shaped member 10. The positioning mechanism 2 is connected to the distal end 12 of the plate-shaped member 10. The positioning mechanism 2 may be located on the distal side of the operating mechanism 1, or it may be at least partially nested in the distal end 12. Exemplarily, the positioning mechanism 2 is cylindrical in shape.

[0050] The rigid tube component 31 is positioned and connected to the plate-shaped component 10 via the positioning mechanism 2. The rigid tube component 31 can be connected to the positioning mechanism 2, and its position along the insertion direction can be positioned to a certain extent by the positioning mechanism 2. A portion of the rigid tube component 31 can extend into the plate-shaped component 10.

[0051] The flexible hose component 32 is located at the plate-shaped component 10.

[0052] The proximal end of the connecting portion 33 connects to the distal end of the flexible hose component 32, and the distal end of the connecting portion 33 connects to the proximal end of the rigid tube component 31. The connecting portion 33 is used to connect the rigid tube component 31 and the flexible hose component 32. The rigid tube component 31 and the flexible hose component 32 can be connected to convey, for example, liquid. The connecting portion 33 is fixedly connected to the plate-shaped component 10. Figure 1 As shown, the side of the plate-shaped component 10 where the connecting part 33 is provided can be referred to as the upper side.

[0053] In the endoscope 100 provided in this embodiment, when the plate-shaped component 10 moves, the connecting portion 33 moves together with the plate-shaped component 10, while the connecting portion 33 itself remains fixed and does not change. The proximal end of the rigid tube component 31 and the distal end of the flexible tube component 32 do not move relative to each other at the connecting portion 33, ensuring a secure and reliable connection between the rigid tube component 31 and the flexible tube component 32, preventing loosening, leakage, or detachment of the rigid tube component 31 and the flexible tube component 32 due to the use of the endoscope 100.

[0054] For example, the distal end of the rigid tube component 31 extends into the positioning mechanism 2, and the flexible tube component 32 is located on the upper side of the plate-shaped component 10.

[0055] For example, the connecting portion 33 is a nut. The proximal end of the rigid tube component 31 is provided with an external thread that mates with the internal thread of the connecting portion 33. The distal end of the flexible tube component 32 is provided with an external thread that mates with the internal thread of the connecting portion 33. The internal thread at the distal end of the connecting portion 33 engages with the external thread at the proximal end of the rigid tube component 31. The internal thread at the proximal end of the connecting portion 33 engages with the external thread at the distal end of the flexible tube component 32. The nut is easy to assemble and can absorb positional deviations between the rigid tube component 31 and the flexible tube component 32. After being fixedly connected to the plate-shaped component 10, the nut will not rotate relative to the rigid tube component 31 and the flexible tube component 32, thereby ensuring reliable connection.

[0056] refer to Figure 3 For example, the aperture of the proximal end of the connecting portion 33 is smaller than the aperture of the distal end of the connecting portion 33. This arrangement facilitates the mating connection between the hose component 32 and the proximal end of the connecting portion 33, and prevents the hose component 32 from detaching from the connecting portion 33.

[0057] In some embodiments, the connecting portion 33 is welded to the plate-shaped component 10. Welding increases the contact area between the connecting portion 33 and the plate-shaped component 10, and improves the strength and reliability of the connection between the connecting portion 33 and the plate-shaped component 10.

[0058] In some embodiments, the connecting portion 33 is bonded to the plate-shaped member 10. Using an adhesive bonding method increases the connection area between the connecting portion 33 and the plate-shaped member 10, making it easier to manufacture and improving the strength and reliability of the connection between the connecting portion 33 and the plate-shaped member 10.

[0059] refer to Figure 2 and Figure 3 In some embodiments, the endoscope 100 further includes a curved portion 6 ( Figure 9 The insertion tube component 35 and the branch tube component 34 are included. The proximal end of the bending section 6 can be indirectly connected to the plate-shaped component 10, and the operating mechanism 1 is used to operate the bending of the bending section 6.

[0060] The insertion tube component 35 is inserted into the positioning mechanism 2. The proximal end of the insertion tube component 35 has a forked opening that connects to the distal end of the branch tube component 34 and the distal end of the rigid tube component 31 respectively.

[0061] The plate-shaped component 10 is provided with a clearance space. Exemplarily, the clearance space is a rectangular groove that penetrates the plate body 11 of the plate-shaped component 10 along the thickness direction of the plate-shaped component 10. The clearance space is used to avoid the rigid tube component 31, so that the rigid tube component 31 can pass through the plate body 11.

[0062] The bending operation member 101 is connected to the lower side of the plate-shaped member 10, and the connecting portion 33 is connected to the upper side of the plate-shaped member 10. The bending operation member 101 is used to control the bending of the bending portion 6, for example, by means of a pull rope (not shown). Since the bending operation member 101 is on one side of the plate-shaped member 10 along the thickness direction, while the connecting portion 33 is fixed to the plate-shaped member 10 and located on the other side of the plate-shaped member 10 along the thickness direction, the connecting portion 33 connecting the rigid tube member 31 and the flexible tube member 32 moves with the plate-shaped member 10 without being affected by the bending operation member 101.

[0063] Refer again Figure 1 In some embodiments, the distal end 12 of the plate-shaped member 10 includes two mating portions 122. A positioning mechanism 2 is fitted onto the two mating portions 122 and onto the rigid tube member 31. A branch tube member 34 extends from the inside of the positioning mechanism 2 to the outside of the positioning mechanism 2 and protrudes from the positioning mechanism 2. The rigid tube member 31 penetrates the plate-shaped member 10 along its thickness direction. The rigid tube member 31 is located between the two mating portions 122.

[0064] In this configuration, the positioning mechanism 2 is connected to the branch tube component 34, which provides an instrument passage, ensuring that the instrument enters the positioning mechanism 2 through the branch tube component 34. The positioning mechanism 2 achieves radial upper limit positioning with the plate-shaped component 10 through the mating part 122. The rigid tube component 31 penetrates the plate-shaped component 10 and is located between the two mating parts 122, which facilitates the assembly of the rigid tube component 31 and the connecting part 33, and also facilitates the relative positioning of the positioning mechanism 2 and the plate-shaped component 10.

[0065] Exemplarily, two mating portions 122 are distributed on both sides of the plate-shaped member 10 in a left-right direction. The two mating portions 122 are detachably connected to the positioning mechanism 2. Exemplarily, the two mating portions 122 are disposed on the upper side of the plate-shaped member 10. The mating portions 122 have a certain width along the circumference of the positioning mechanism 2, and the mating portions 122 are stably fitted with the positioning mechanism 2, and the mating portions 122 are suitable for being locked with screws.

[0066] For example, the rigid tube component 31 passes through the clearance space from the underside of the plate-shaped component 10, is located on the upper side of the plate-shaped component 10, and is situated between the two mating portions 122.

[0067] For example, a connecting portion is provided between the inner and outer sides of the positioning mechanism 2, and the branch pipe component 34 extends out of the positioning mechanism 2 from the connecting portion of the positioning mechanism 2.

[0068] Refer again Figure 1In some embodiments, the distal end 12 of the plate-shaped component 10 includes two fitting portions 121, which are fitted and fixedly connected to the positioning mechanism 2. The fitting portions 121 are fixedly connected to the positioning mechanism 2, thereby enabling a firm and reliable connection between the plate-shaped component 10 and the positioning mechanism 2. This avoids the problem that relative movement between the plate-shaped component 10 and the positioning mechanism 2 due to the use of the endoscope 100 would cause an increase in the control error of the bending operation component 101 on the bending portion 6.

[0069] Exemplarily, two fitting portions 121 are distributed on both sides of the plate-shaped member 10 in a left-right direction. Exemplarily, the fitting portions 121 extend along the length direction of the plate-shaped member 10. The fitting portions 121 are disposed parallel to the plate-shaped member 10 and fixed to the outer side of the plate-shaped member 10.

[0070] For example, the distal end of the fitting part 121 is provided with a fitting groove, and the positioning mechanism 2 is engaged with the fitting groove of the fitting part 121.

[0071] refer to Figures 4 to 7 In some embodiments, the plate-shaped component 10 further includes a plate body 11 and a wedge 13. The plate body 11 has a guide groove 111, and the wedge 13 is disposed in the guide groove 111. The bottom of the guide groove 111 is inclined relative to the connecting portion 33, so that the wedge 13 abuts against the connecting portion 33 and the plate-shaped component 10. Exemplarily, the connecting portion 33 is inclined relative to the plate body 11. The inclination of the bottom of the guide groove 111 relative to the connecting portion 33 facilitates the abutment of the wedge 13 against the guide groove 111 and the connecting portion 33, and helps to increase the tightness and friction between the wedge 13 and the connecting portion 33.

[0072] In another embodiment, a guide groove 111 is provided at the position corresponding to the connecting part 33 on the plate 11, and the inclination direction of the bottom of the guide groove 111 is the same as the inclination direction of the connecting part 33. A part of the wedge 13 extends into the guide groove 111 and abuts against the guide groove 111, and another part of the wedge 13 protrudes from the upper side of the plate 11 and abuts against the connecting part 33.

[0073] For example, the included angle between the two wedge faces of the wedge 13 is substantially the same as the included angle between the bottom of the guide groove 111 and the side of the connecting portion 33. In other embodiments, the thickness of the wedge 13 is uniform, and the degree of inclination is such that the wedge 13 abuts against the connecting portion 33.

[0074] refer to Figures 4 to 8 In some embodiments, the connector 33 is configured to be rotatably connected to the rigid tube member 31. The connector 33 has a snap-fit ​​groove 331, at least one sidewall of which is constrained by the sidewall of the wedge 13.

[0075] With this configuration, the side wall of the wedge 13 can engage with the snap-fit ​​groove 331 of the connecting part 33 to lock the connecting part 33, preventing the connecting part 33 from rotating and causing the rigid pipe component 31 and the flexible pipe component 32 to loosen or detach.

[0076] refer to Figure 7 The connecting part 33 is provided with multiple snap-fit ​​grooves 331 along its circumference, which not only helps to rotate the connecting part 33, but also allows a corresponding snap-fit ​​groove 331 to engage with the wedge block 13 based on the actual rotation position of the connecting part 33.

[0077] refer to Figure 8 For example, the width of the snap-fit ​​groove 331 corresponding to the wedge 13 is relatively large. The connecting portion 33 can be rotated to an angle that aligns the snap-fit ​​groove 331 with the wedge 13. At least one sidewall of the snap-fit ​​groove 331 is constrained by the sidewall of the wedge 13.

[0078] In some embodiments, the connecting part 33 is fixedly connected to the wedge block 13, and the plate-shaped member 10 is fixedly connected to the wedge block 13. The connecting part 33 is fixedly connected to the plate-shaped member 10 through the wedge block 13, thereby enabling a firm and reliable connection between the rigid tube member 31 and the flexible tube member 32, preventing the rigid tube member 31 and the flexible tube member 32 from loosening, leaking or detaching due to the use of the endoscope 100.

[0079] For example, the plate-shaped component 10 is welded to the wedge block 13. The snap-fit ​​groove 331 of the connecting portion 33 is welded to the two side walls of the wedge block 13.

[0080] For example, the plate-shaped component 10 is bonded to the wedge block 13. The snap-fit ​​groove 331 of the connecting portion 33 is bonded to the two side walls of the wedge block 13.

[0081] In other embodiments, the plate-shaped component 10 and the wedge block 13 may be welded to the connecting portion 33, respectively.

[0082] refer to Figure 6 For example, the endoscope 100 may include two wedges 13 and two locking grooves 331. The two locking grooves 331 are located on both sides of the connecting portion 33 in the left-right direction, and the two wedges 13 are inclined on both sides of the connecting portion 33 in the left-right direction. The two wedges 13 are respectively welded to the plate-shaped component 10, and each wedge 13 is welded to one locking groove 331. This arrangement can increase the stability of the welded structure and prevent the two wedges 13 from shaking; it also increases the operating space, making it easier to achieve a fixed connection; and it can also prevent the entire connecting portion 33 from shaking, preventing the risk of endoscope failure.

[0083] This disclosure also provides an endoscope 100, which includes a manipulation mechanism 1, a positioning mechanism 2, and a tubing assembly 3. The manipulation mechanism 1 includes a plate-shaped member 10 and is used to manipulate the tubing assembly 3. The positioning mechanism 2 is fixedly connected to the distal end 12 of the plate-shaped member 10. The tubing assembly 3 is positioned and connected to the plate-shaped member 10 via the positioning mechanism 2.

[0084] In the endoscope 100 provided in this embodiment, the positioning mechanism 2 positions the plate-shaped component 10 relative to the tubing assembly 3, and by being fixedly connected to the plate-shaped component 10, prevents it from moving relative to the plate-shaped component 10 due to the use of the endoscope 100.

[0085] Exemplarily, the actuating mechanism 1 includes a plate-shaped member 10. The plate-shaped member 10 is cuboid in shape. A positioning mechanism 2 is connected to the plate-shaped member 10, with the distal end 12 of the plate-shaped member 10 connected to the proximal end of the positioning mechanism 2. The positioning mechanism 2 is generally cylindrical in shape. The proximal end of a conduit assembly 3 is located on the plate-shaped member 10, and the conduit assembly 3 passes through the positioning mechanism 2.

[0086] In some embodiments, the positioning mechanism 2 is welded or bonded to the distal end 12 of the plate-like component 10. The welding or bonding method can securely and reliably connect the plate-like component 10 and the positioning mechanism 2, preventing the plate-like component 10 and the positioning mechanism 2 from becoming loose due to the use of the endoscope 100.

[0087] In some embodiments, the distal end 12 of the plate-shaped component 10 includes two fitting portions 121, which are fitted and fixedly connected to the positioning mechanism 2. By providing two fitting portions 121 fixedly connected to the positioning mechanism 2, the plate-shaped component 10 and the positioning mechanism 2 can be securely and reliably connected, preventing relative movement between the plate-shaped component 10 and the positioning mechanism 2 due to the use of the endoscope 100, and avoiding the bending operation component 101 from affecting the bending portion 6 ( Figure 9 The control error increases.

[0088] Exemplarily, the fitting portion 121 is parallel to the plate body 11. The positioning mechanism 2 has a radially slotted design. The fitting portion 121 can be fitted into the slot of the positioning mechanism 2 to limit the rotational position of the plate-shaped component 10 relative to the positioning mechanism 2. Exemplarily, before the positioning mechanism 2 is welded or bonded to the plate-shaped component 10 during the assembly of the endoscope 100, the positioning mechanism 2 can be connected to the mating portion 122 by screws. The fitting portion 121 and the mating portion 122 can form a T-shaped structure, resulting in high structural strength of the plate-shaped component 10.
