Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, specifically to an endoscope lens tip and an endoscope. Background Technology

[0002] ERCP (Endoscopic Retrograde Cholangiopancreatography) is a procedure used to diagnose and treat pancreatic and biliary problems. During ERCP, a papillary scalpel and an endoscope are used together. The papillary scalpel is inserted into the patient's body through the endoscope's forceps cannula and then lifted to the target position using the endoscope's lifter, thereby making an incision in the duodenal papilla for subsequent treatment.

[0003] The tip of the nipple cutter can release a high-frequency current to cut the duodenal papilla. Since the forceps are usually made of metal, if the insulation layer of the tip is damaged or if the operation is improper, the tip can become electrified when it comes into contact with the forceps, affecting the safety of the endoscope. Therefore, the endoscope tip is usually equipped with an insulating cap and an insulating ring to isolate the metal tip from the patient's cavity tissue. The insulating ring is located at the base of the metal tip and provides radial restraint.

[0004] When using ethylene oxide or low-temperature plasma to sterilize endoscopes, the performance of the insulating ring may be affected. Therefore, the insulating ring needs to be replaced regularly to ensure the safety of the endoscope. Alternatively, when it is necessary to replace components installed in the metal tip mount, the insulating ring must first be removed to release its radial constraint on the metal tip mount. However, the current procedure for replacing the insulating ring is cumbersome and difficult, which greatly affects the maintenance efficiency of the endoscope tip. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, an endoscope lens tip is provided, the technical solution of which is as follows.

[0006] The endoscope tip includes a headstock and an insulating ring. The headstock has a proximal end. The insulating ring is fitted around the outer periphery of the proximal end and has a first connecting portion and a second connecting portion arranged circumferentially opposite each other, the first connecting portion and the second connecting portion being detachably connected.

[0007] In this invention, when the first connecting part and the second connecting part are connected at the end of the endoscope, the insulating ring can be fitted onto the outer side of the proximal end. When the insulating ring needs to be replaced, the first connecting part and the second connecting part can be separated, allowing the insulating ring to be directly removed along the radial direction of the endcap. This effectively simplifies the installation and removal steps of the insulating ring, reduces the difficulty of replacing the insulating ring, improves the efficiency and convenience of replacing the insulating ring, and thus enhances the maintenance efficiency of the endoscope end.

[0008] For example, the insulating ring includes two or more parts that are connected end to end in the circumferential direction, and two adjacent parts are detachably connected by a first connecting part and a second connecting part.

[0009] For example, the first connecting portion has a first abutting surface, and the second connecting portion has a second abutting surface. One of the first and second abutting surfaces has a protrusion, and the other has a recess that matches the protrusion. When the first and second connecting portions are circumferentially joined, the protrusion is inserted into the recess, and the first abutting surface abuts against other portions of the second abutting surface circumferentially.

[0010] For example, when the protrusion is inserted into the recess, the protrusion and the recess are in an interference fit.

[0011] For example, a first adhesive is filled between the first abutting surface and the second abutting surface, and the first adhesive has the characteristic of being prone to failure after heating.

[0012] For example, a second adhesive is filled between the inner wall and the proximal end of the insulating ring, the second adhesive having the property of being prone to failure upon heating.

[0013] For example, the radial depth of the groove gradually increases along the direction from the proximal end to the distal end.

[0014] For example, the grooves are respectively offset from the first connecting portion and the second connecting portion in the circumferential direction.

[0015] For example, the head end seat also has a mounting portion extending from the proximal end to the distal end, and one or more stepped surfaces are formed at the connection between the proximal end and the mounting portion, and a portion of the distal edge of the insulating ring abuts against one or more stepped surfaces axially; the groove is circumferentially offset from one or more stepped surfaces.

[0016] For example, the mounting portion includes a first mounting portion and a second mounting portion disposed opposite to each other, and the endoscope lens end portion also includes a camera assembly; the camera assembly is mounted on the first mounting portion, and the groove is located on the same side of the second mounting portion.

[0017] For example, the outer wall of the second mounting portion is recessed inward to form a notch, and the proximal end of the notch extends to the proximal end. The insulating ring is formed with a clearance opening corresponding to the notch, and a groove is provided on the base end side of the clearance opening.

[0018] For example, the endoscope also includes a head cap fitted over the head end seat, the proximal end of the insulating ring extending outward in its radial direction to form an abutment portion, and when the head cap is fitted over the head end seat, the inner wall of the head cap is press-fitted with at least a portion of the outer wall of the insulating ring, and the head cap abuts against the abutment portion.

[0019] According to another aspect of the present invention, an endoscope is also provided, including an endoscope lens end as described above.

[0020] The endoscope of this utility model includes the endoscope lens end as described above. Since the endoscope lens end has the beneficial effects described above, the endoscope including the endoscope lens end as described above must also have the beneficial effects described above.

[0021] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0034] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein. Based on the embodiments of this utility model described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this utility model.

[0035] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0036] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0037] In existing endoscopes, the curved section at the end cap can cause the headstock to swing, aligning the camera, illumination window, and water / air nozzles within the headstock towards the target area. An insulating ring is integrally fitted at the connection between the headstock and the curved section. Replacing the insulating ring requires first disconnecting the headstock from the curved section and then removing the insulating ring axially from the headstock. However, the connection structure between the headstock and the curved section is complex, and many components penetrate both, making the disassembly and assembly process cumbersome. Furthermore, the integrally formed insulating ring is difficult to disassemble; even with destructive removal, the lack of a point of force for destructive removal on the insulating ring makes quick and convenient replacement impossible.

[0038] Based on this, one embodiment of the present invention provides an endoscope lens tip that effectively reduces the difficulty and convenience of replacing the insulating ring. Therefore, whether replacement is required due to insulating ring failure or failure of internal components of the headstock, no disassembly or reassembly of the headstock and the bent portion is necessary, greatly improving the maintenance efficiency of the endoscope lens tip. The following will describe in detail an endoscope lens tip according to an embodiment of the present invention with reference to the accompanying drawings.

[0039] like Figures 1 to 3 As shown, the endoscope tip includes a headstock 1 and an insulating ring 2. The headstock 1 has a proximal end portion 11. The insulating ring 2 is sleeved on the outer periphery of the proximal end portion 11. The insulating ring 2 has a first connecting portion 21 and a second connecting portion 22 arranged circumferentially opposite each other, and the first connecting portion 21 and the second connecting portion 22 are detachably connected.

[0040] The headstock 1 can be a metal part, on which a camera assembly 7, an illumination window, a water and air nozzle, an instrument channel, and a lifting clamp can be installed to realize the main functions of the endoscope, such as image transmission, illumination, water and air supply, instrument extension, and changing the direction of instrument extension.

[0041] The proximal end 11 of the headpiece 1 described above can be represented as the end of the headpiece 1 closest to the operator of the endoscope. It is understood that, unless otherwise specified, the distal end or head end in this document refers to the end away from the operator of the endoscope along the length axis of the endoscope, while the proximal end or base end refers to the end closest to the operator of the endoscope.

[0042] The insulating ring 2 can be made of insulating materials, such as plastic or rubber, and this application does not specifically limit it.

[0043] Detachable connections may include adhesive connections, plug-in connections, or snap-fit ​​connections, etc., and this application does not specifically limit them. The first connecting part 21 and the second connecting part 22 are connected by a detachable connection, which can greatly facilitate the connection or separation between the first connecting part 21 and the second connecting part 22.

[0044] The first connecting portion 21 and the second connecting portion 22 described above can be arranged in pairs along the circumferential direction. When each pair of the first connecting portion 21 and the second connecting portion 22 is connected, the insulating ring 2 can be firmly fixed to the proximal end 11 of the head end seat 1. When the first connecting portion 21 and the second connecting portion 22 are separated, a notch can be formed in the circumferential direction of the insulating ring 2, so that the insulating ring 2 can be easily removed through the notch. Of course, the insulating ring 2 can also be pulled to destructively remove it.

[0045] In the endoscope lens of this invention, when the first connecting part 21 and the second connecting part 22 are connected, the insulating ring 2 can be fitted onto the outside of the proximal end 11. When the insulating ring 2 needs to be replaced, the first connecting part 21 and the second connecting part 22 can be separated, allowing the insulating ring 2 to be directly removed along the radial direction of the headstock 1. Thus, the insulating ring 2 can be separated from the headstock 1 without performing the disassembly and assembly operation between the headstock 1 and the bent part 9 (described later), effectively simplifying the disassembly and assembly steps of the insulating ring 2, reducing the difficulty of replacing the insulating ring 2, and improving the maintenance efficiency of the endoscope lens.

[0046] In some embodiments, the insulating ring 2 may include two or more parts, which are connected end to end in the circumferential direction, and adjacent parts are detachably connected by a first connecting part 21 and a second connecting part 22.

[0047] For example, such as Figure 3 , Figures 5 to 7 As shown, the insulating ring 2 can have two parts, and the ends of the two parts can be formed with corresponding first connecting parts 21 and second connecting parts 22. Through the connection between the two pairs of first connecting parts 21 and second connecting parts 22, the two parts can be enclosed to form an annular insulating ring 2.

[0048] In the above embodiments, the insulating ring 2 can be formed by two or more parts enclosing each other. In this way, the difficulty and time of disassembling and assembling the insulating ring 2 can be significantly reduced by splicing, thus improving the convenience of disassembling and assembling the insulating ring 2.

[0049] In some embodiments, such as Figure 5 and Figure 6 As shown, the first connecting portion 21 has a first abutting surface 211, and the second connecting portion 22 has a second abutting surface 221. One of the first abutting surface 211 and the second abutting surface 221 is provided with a protrusion 4, and the other of the first abutting surface 211 and the second abutting surface 221 is provided with a recess 5 that matches the protrusion 4. When the first connecting portion 21 and the second connecting portion 22 are joined circumferentially, the protrusion 4 is inserted into the recess 5, and the first abutting surface 211 abuts against the other parts of the second abutting surface 221 circumferentially.

[0050] The first abutting surface 211 can be specifically represented as the wall surface of the first connecting portion 21 facing the second connecting portion 22. Similarly, the second abutting surface 221 can be specifically represented as the wall surface of the second connecting portion 22 facing the first connecting portion 21.

[0051] The number of protrusions 4 and recesses 5 can be multiple, and this application does not specifically limit this. For example, the number of protrusions 4 and recesses 5 can be one, two, or three, respectively. Figure 6 As shown, there are three convex parts 4 and three concave parts 5.

[0052] The shape of the protrusion 4 can be cylindrical, square, or triangular, etc., and the shape of the concave part 5 can be adapted to the shape of the protrusion 4. This application does not make specific limitations in this regard.

[0053] In the above embodiment, the insertion connection between the protrusion 4 and the recess 5 not only ensures the stability and reliability of the connection between the first connecting part 21 and the second connecting part 22, but also facilitates the connection or separation of the first connecting part 21 and the second connecting part 22, further improving the efficiency and convenience of replacing the insulating ring 2. Furthermore, when the first connecting part 21 and the second connecting part 22 are circumferentially mated, the first abutting surface 211 can abut against other parts of the second abutting surface 221 circumferentially, allowing surface contact to be formed between the first connecting part 21 and the second connecting part 22, thereby effectively ensuring the stability of the connection between the two.

[0054] In some embodiments, when the protrusion 4 is inserted into the recess 5, the protrusion 4 and the recess 5 are in an interference fit.

[0055] In the above embodiment, the interference fit between the protrusion 4 and the recess 5 allows the first connecting portion 21 and the second connecting portion 22 to fit tightly together, ensuring the strength and stability of the connection between them. Furthermore, the interference fit eliminates the need for additional fasteners (such as bolts, screws, etc.), effectively reducing the manufacturing and assembly costs of the insulating ring 2.

[0056] In some embodiments, a first adhesive (not shown) is filled between the first abutting surface 211 and the second abutting surface 221. The first adhesive has the characteristic of being prone to failure after heating.

[0057] Because there may be errors between individual parts of the insulating ring 2 during the processing, there may be gaps between the first abutting surface 211 and the second abutting surface 221 when they abut. The first adhesive can not only firmly bond the first abutting surface 211 and the second abutting surface 221, but also fill the gaps between the first abutting surface 211 and the second abutting surface 221.

[0058] Furthermore, the first adhesive is prone to failure upon heating. Therefore, when it is necessary to separate the first connecting part 21 and the second connecting part 22, a heating device can be used to heat the first adhesive, causing it to overheat in a short time and resulting in adhesive failure. The heating device can be a heat gun, etc., and this application does not specifically limit it.

[0059] In the above embodiments, when the first connecting portion 21 and the second connecting portion 22 are in a connected state, the first adhesive can be located between the first abutting surface 211 and the second abutting surface 221 to fill the gap between the first connecting portion 21 and the second connecting portion 22, thereby further improving the firmness of the connection between the first connecting portion 21 and the second connecting portion 22. Furthermore, it can also avoid the possibility of cleaning dead zones in the insulating ring 2, effectively improving the safety of using the insulating ring 2. When it is necessary to remove the insulating ring 2, the first adhesive can be heated to deactivate it, thereby facilitating the removal of the insulating ring 2.

[0060] In some embodiments, a second adhesive (not shown) is filled between the inner wall of the insulating ring 2 and the proximal end 11. The second adhesive has the property of being prone to failure upon heating.

[0061] Because there may be errors in the processing of the head end seat 1 and the insulating ring 2, there will be gaps when the insulating ring 2 is fitted onto the outer periphery of the proximal end 11. The second adhesive can not only firmly bond the insulating ring 2 and the proximal end 11, but also fill the gap between the inner wall of the insulating ring 2 and the proximal end 11.

[0062] When it is necessary to separate the insulating ring 2 and the proximal end 11, a heating device can be used to heat the second adhesive, causing it to overheat in a short time, thereby leading to adhesive failure. The heating device can be a heat gun, etc., and this application does not specifically limit it.

[0063] In the above embodiment, when the insulating ring 2 is fitted onto the outer periphery of the proximal end 11, the second adhesive can be located between the inner wall of the insulating ring 2 and the proximal end 11 to fill the gap between the insulating ring 2 and the proximal end 11, thereby improving the firmness of the connection between the insulating ring 2 and the proximal end 11. Furthermore, it avoids the possibility of cleaning dead zones at the end of the endoscope, effectively improving the safety of using the endoscope. When it is necessary to disassemble the insulating ring 2, the second adhesive can be heated to dissolve it, thus facilitating the disassembly of the insulating ring 2.

[0064] In some embodiments, such as Figure 7 As shown, a groove 6 extending to the distal end of the insulating ring 2 is formed on the inner wall of the insulating ring 2, and a second adhesive is filled between the groove 6 and the outer wall of the proximal end 11.

[0065] The distal end of the insulating ring 2 can be specifically defined as the end of the insulating ring 2 away from the operator of the endoscope. The groove 6 can extend to the distal end of the insulating ring 2 to form an opening at the distal end of the insulating ring, which serves as a point of force application for disassembling the insulating ring 2.

[0066] When it is necessary to replace the insulating ring 2, a heating device can be used to heat the second adhesive in the groove 6, causing it to overheat in a short time and resulting in adhesive failure. At this point, after removing the second adhesive from the groove 6, a mechanical tool can be inserted into the groove 6 from the distal end and the insulating ring 2 can be removed by prying. The heating device can be a heat gun, etc., and this application does not specifically limit its use.

[0067] In the above embodiment, the groove 6 can be filled with a second adhesive, which ensures the firmness and tightness between the insulating ring 2 and the proximal end 11. Furthermore, when it is necessary to remove the insulating ring 2, the second adhesive in the groove 6 can be locally heated and cleaned, and then a mechanical tool can be used to extend into the groove 6 from the distal end to remove the insulating ring 2. This allows for easier application of force to the insulating ring 2, significantly improving the convenience of replacing the insulating ring 2.

[0068] In some embodiments, such as Figure 7 As shown, the radial depth of groove 6 gradually increases along the direction from the proximal end to the distal end.

[0069] In the above embodiment, the radial depth of the groove 6 can be gradually increased, so that a roughly V-shaped space can be formed between the bottom of the groove 6 and the outer wall surface of the near end 11, thereby making it easier for mechanical equipment (such as a flathead screwdriver) to be aligned and inserted into the groove 6, and thus better apply force to the insulating ring 2, further improving the convenience of replacing the insulating ring 2.

[0070] In some embodiments, such as Figure 3 , Figures 5 to 7 As shown, the groove 6 is circumferentially offset from the first connecting part 21 and the second connecting part 22.

[0071] In the above embodiment, the groove 6 can be at a certain distance from the first connecting part 21 and the second connecting part 22 in the circumferential direction, so as to avoid interference with the first connecting part 21 and the second connecting part 22, thereby ensuring the stability and firmness of the connection between the first connecting part 21 and the second connecting part 22.

[0072] In some embodiments, such as Figure 3 and Figure 4As shown, the head end seat 1 also has a mounting portion 12 extending from the proximal end 11 to the distal end. One or more stepped surfaces 13 are formed at the connection between the proximal end 11 and the mounting portion 12. A portion of the distal edge of the insulating ring 2 abuts against one or more stepped surfaces 13 in the axial direction. The groove 6 is circumferentially offset from one or more stepped surfaces 13.

[0073] The mounting portion 12 can be used to install devices such as camera assembly 7, lighting window, water vapor nozzle, lifting clamp and rotating arm 10. The radial dimension of the mounting portion 12 can be larger than the radial dimension of the proximal end portion 11, so that at least one stepped surface 13 can be formed at the connection between the proximal end portion 11 and the mounting portion 12. When the insulating ring 2 is fitted on the outside of the proximal end portion 11, the distal end of the insulating ring 2 can abut against the stepped surface 13 to prevent the insulating ring 2 from coming off the distal end of the head end seat 1.

[0074] The number of the above-mentioned grooves 6 can be multiple, and the multiple grooves 6 can be arranged in a ring along the outer wall of the near end 11. The grooves 6 can be circumferentially offset from at least one stepped surface 13.

[0075] In the above embodiments, a stable connection between the insulating ring 2 and the proximal end 11 can be achieved through at least one abutment surface 13, avoiding the situation where the insulating ring 2 and the headstock 1 detach when using the end of the endoscope, effectively improving the reliability of the endoscope end. Furthermore, the groove 6 can be circumferentially offset from one or more stepped surfaces 13, thereby avoiding interference with the stepped surfaces 13 when prying the groove 6 with mechanical tools, thus preventing any impact on the disassembly of the insulating ring 2 and effectively improving the ease of disassembling the insulating ring 2.

[0076] In some embodiments, such as Figure 2 As shown, the mounting part 12 includes a first mounting part 121 and a second mounting part 122 disposed opposite to each other, and the end of the endoscope lens also includes a camera assembly 7; the camera assembly 7 is mounted on the first mounting part 121, and the groove 6 is located on the same side of the second mounting part 122.

[0077] The first mounting part 121 and the second mounting part 122 can be arranged opposite to each other in the radial direction of the mounting part 12. The camera component 7 can be disposed on the first mounting part 121. The camera component 7 can be used to capture and collect images to ensure that the user can see continuous and dynamic images during operation, thereby making diagnosis and treatment more accurate.

[0078] In the above embodiment, the camera component 7 can be installed on the first mounting part 121, and the groove 6 can be located on the same side of the second mounting part 122. This allows the camera component 7 and the groove 6 to have a certain distance in the radial direction of the mounting part 12, so as to avoid affecting and damaging the camera component 7 when the second adhesive in the groove 6 is heated. This effectively improves the service life of the camera component 7, thereby reducing the frequency of replacing the insulating ring 2 and improving the service life and reliability of the endoscope lens end.

[0079] In some embodiments, such as Figure 3 and Figure 8 As shown, the outer wall of the second mounting portion 122 is recessed inward to form a notch 123, and the proximal end of the notch 123 extends to the proximal end 11. The insulating ring 2 is formed with a clearance opening 222 corresponding to the notch 123, and the groove 6 is provided on the base end side of the clearance opening 222.

[0080] A rotating arm 10 may be mounted on the second mounting portion 122 and accommodated within the recess 123. The rotating arm 10 can be used to control the rotation angle of the clamp lifter (lifting or lowering). One end of the rotating arm 10 is connected to a traction line passing through the proximal end portion 11, and the clamp lifter is rotated under the control of the traction line. The proximal end of the recess 123 extends to the proximal end portion 11, and the insulating ring 2 forms a clearance opening 222 corresponding to the recess 123. This avoids interference and influence on the movement of the rotating arm 10 by the outer wall of the second mounting portion 122 and the insulating ring 2 when the traction line drives the rotating arm 10 to rotate, thereby preventing the accuracy of the clamp lifter's movement from being affected.

[0081] The groove 6 can be set on the base end side of the clearance opening 222, so that the groove 6 can be processed at the same time as the clearance opening 222, effectively reducing the manufacturing difficulty of the insulating ring 2. In addition, the distal end side of the clearance opening 222 is the opening area of ​​the notch 123. By simply pushing the rotating arm 10 to the distal end side, a larger open area can be formed, which facilitates the insertion of mechanical tools into the groove 9 and the implementation of prying operations.

[0082] In the above embodiment, a notch 123 may be formed on the outer wall of the second mounting portion 122, and a clearance opening 222 corresponding to the notch 123 may be formed on the insulating ring 2. This prevents the rotating arm 10 and other devices installed in the mounting portion 12 from colliding with the mounting portion 12 and the insulating ring 2 during rotation, effectively ensuring the accuracy of the clamping device's movement and thus improving the reliability of the endoscope lens tip. The groove 6 is correspondingly provided on the base end side of the clearance opening 222, providing a larger operating space for mechanical work and facilitating the disassembly of the insulating ring 2.

[0083] In some embodiments, such as Figures 1 to 3As shown, the endoscope also includes a head cap 3 fitted over the head end seat 1. The proximal end of the insulating ring 2 extends outward along its radial direction to form an abutment portion 23. When the head cap 3 is fitted over the head end seat 1, the inner wall of the head cap 3 is press-fitted with at least a portion of the outer wall of the insulating ring 2, and the head cap 3 abuts against the abutment portion 23.

[0084] The head cap 3 can be made of non-metallic insulating material to cover and isolate the head base 1. When the head cap 3 is fitted onto the head base 1, the end of the head cap 3 closest to the operator can cover at least part of the insulating ring 2 for better protection.

[0085] The end of the insulating ring 2 closest to the operator can extend radially outward to form an abutment portion 23, which can axially limit the head cap 3.

[0086] In the above embodiments, when the end cap 3 is fitted over the end base 1, the inner wall of the end cap 3 can be press-fitted with at least a portion of the outer wall of the insulating ring 2. This ensures a secure connection between the end cap 3 and the insulating ring 2 without requiring additional connecting structures. Furthermore, the end cap 3 can abut against the abutment portion 23 to define the installation position of the end cap 3, preventing inaccurate positioning during installation and effectively ensuring the accuracy of the connection position between the end cap 3 and the insulating ring 2, thereby guaranteeing the reliability of the end of the endoscope.

[0087] According to another aspect of this utility model, such as Figure 9 As shown, an endoscope is also provided, including the endoscope lens end as described above.

[0088] The endoscope may also include an insertion section 8 and a bending section 9. The insertion section 8 may be elongated to allow it to enter the body through natural orifices or open incisions, such as the mouth or esophagus.
