In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0043] See also Figures 1 to 18 As shown, according to an embodiment of the present application, an endoscope is provided, and the endoscope includes a handle assembly. The handle assembly includes a handle body 10, a light guide bundle 20, and a heat insulation sleeve 30. It should be noted that the handle assembly in this embodiment can be used in addition to an endoscope, and can also be used in other devices connected to the light guide bundle 20.
[0044] Among them, a first joint 11 is provided at one end of the main body. A second joint 21 adapted to the first joint 11 is provided on the light guide beam 20, the first joint 11 is connected to the second joint 21, and the heat insulation sleeve 30 is sleeved on the outer periphery of the first joint 11 and the second joint 21. The heat insulation sleeve 30 has a state of covering the outer periphery of the first joint 11 and / or the second joint 21, and a state of exposing the first joint 11 and / or the second joint 21. In this embodiment, the first joint 11 is a metal female head, and the second joint 21 is a metal male head adapted to the metal female head.
[0045] It should be noted that: "the insulation sleeve 30 is in a state of covering the periphery of the first joint 11 and / or the second joint 21" means one of the three states that the insulation sleeve 30 covers the periphery of the first joint 11, the insulation sleeve 30 covers the periphery of the second joint 21, and the insulation sleeve 30 covers the periphery of the first joint 11 and the periphery of the second joint 21; similarly, "the insulation sleeve 30 has a state of exposing the first joint 11 and / or the second joint 21" means one of the three states that the insulation sleeve 30 has a state of exposing the first joint 11, the insulation sleeve 30 has a state of exposing the second joint 21, and the insulation sleeve 30 has a state of exposing both the first joint 11 and the second joint 21.
[0046] Specifically, an optical fiber is arranged in the light guide bundle 20. When the optical fiber is connected to the first joint 11 of the handle body 10 through the second joint 21, a large amount of heat energy will be generated at the first joint 11 and the second joint 21, so that the temperature at the first joint 11 and the second joint 21 is too high, and the operator is easily burned after contact. In this embodiment, a heat insulation sleeve 30 is also arranged on the handle assembly. The heat insulation sleeve 30 is sleeved on the outer periphery of the first joint 11 and the second joint 21. The heat insulation sleeve 30 has a state of covering the outer periphery of the first joint 11 and / or the second joint 21, and a state of exposing the first joint 11 and / or the second joint 21. The heat insulation sleeve 30 has a certain heat insulation capacity, and when the heat insulation sleeve 30 is covered on the outer periphery of the first joint 11 and the second joint 21, the first joint 11 and the second joint 21 with higher temperature can be isolated from the outside world, thereby preventing the operator from directly contacting the first joint 11 or the second joint 21 when using the endoscope, thereby preventing the operator from being burned.
[0047] In some embodiments, the heat insulating sleeve 30 is a silicone sleeve. On the one hand, the silicone sleeve has high temperature resistance, which can prevent the first joint 11 and the second joint 21 from being burned by excessive temperature; on the other hand, the silicone sleeve has a low thermal conductivity and good heat insulation performance, so it can slow down the transfer of heat from the first joint 11 and the second joint 21 to the external environment of the silicone sleeve. In other embodiments, the heat insulating sleeve 30 can also be a high temperature resistant plastic sleeve, such as a polypropylene plastic sleeve or a polytetrafluoroethylene plastic sleeve.
[0048] Furthermore, a limiting groove 111 is provided on one of the outer peripheral side wall surface of the first joint 11 and the inner wall surface of the heat insulation sleeve 30 close to the first joint 11 , and a limiting protrusion 301 adapted to the limiting groove 111 is provided on the other of the two.
[0049] In a specific embodiment, as shown in the attached Figure 2 As shown, the inner wall surface of the heat insulation sleeve 30 near the first joint 11 is provided with a limiting protrusion 301, and the outer peripheral side wall surface of the first joint 11 is provided with a limiting groove 111. Figure 3As shown, the heat-insulating sleeve 30 is firstly sleeved on the light-guiding beam 20, and then the first joint 11 and the second joint 21 are connected, and then the heat-insulating sleeve 30 is pushed to the periphery of the first joint 11 and the second joint 21, and the limiting protrusion 301 on the heat-insulating sleeve 30 is pressed against the limiting groove 111 on the peripheral side wall of the first joint 11, so as to limit the heat-insulating sleeve 30. In this embodiment, a plurality of limiting grooves 111 are provided, and the plurality of limiting grooves 111 are arranged at intervals along the radial direction of the first joint 11, and a plurality of limiting protrusions 301 are also provided, and the plurality of limiting protrusions 301 are arranged at intervals along the radial direction of the heat-insulating sleeve 30, and correspond one by one to the plurality of limiting grooves 111. In addition, in this embodiment, the limiting protrusion 301 is an arc-shaped protrusion, and the limiting groove 111 is an arc-shaped groove, so as to reduce the wear of the limiting protrusion 301 when it cooperates with the limiting groove 111.
[0050] Furthermore, an anti-scalding sleeve 40 is provided on the outer periphery of one end of the first joint 11 close to the handle body 10 . During actual processing or assembly, the heat insulating sleeve 30 may abut against the anti-scalding sleeve 40 , or may be integrally formed with the anti-scalding sleeve 40 .
[0051] Specifically, since the first joint 11 is connected to the handle body 10, when the temperature of the first joint 11 is too high, the excessively high temperature may cause the temperature of the end of the first joint 11 close to the handle body 10 to be too high, and eventually cause the operator to be burned when accidentally touched. Therefore, in this embodiment, an anti-scalding sleeve 40 is sleeved on the outer periphery of the end of the first joint 11 close to the handle body 10, thereby isolating the temperature on the first joint 11. In some embodiments, such as the attached Figure 1 and attached Figure 4 As shown, the heat insulating sleeve 30 and the anti-scalding sleeve 40 are separately provided, and the heat insulating sleeve 30 abuts against the anti-scalding sleeve 40 after assembly, so as to better isolate the heat on the first joint 11 and the second joint 21. In other embodiments, for example, Figure 7 and attached Fig.10 As shown, the heat insulation sleeve 30 and the anti-scalding sleeve 40 are integrally formed, and the heat insulation sleeve 30 and the anti-scalding sleeve 40 can usually be integrally injection molded. In this embodiment, the anti-scalding sleeve 40 is usually a silicone sleeve, and the anti-scalding sleeve 40 can also be a polypropylene plastic sleeve or a polytetrafluoroethylene plastic sleeve.
[0052] In a specific embodiment, as shown in the attached Figure 4 To Attachment Figure 6 As shown, the insulation sleeve 30 is connected to the second joint 21 by interference fit, and the end of the insulation sleeve 30 close to the light guide beam 20 has a first state that covers the outer periphery of the first joint 11 and abuts against the anti-scalding sleeve 40, and a second state that is folded by external force to expose the first joint 11.
[0053] Specifically, during assembly, the heat insulating sleeve 30 is first turned over to put the heat insulating sleeve 30 in the second state, and the second joint 21 is connected to the first joint 11; then the heat insulating sleeve 30 is restored to cover the first joint 11. The handle assembly of this embodiment has a simple structure and is easy to assemble. In addition, in this embodiment, a convex point 302 is provided on the inner side wall of the heat insulating sleeve 30 near the second joint 21, so that the heat insulating sleeve 30 can be interference-fitted on the second joint 21.
[0054] Furthermore, when the heat insulating sleeve 30 abuts against the anti-scalding sleeve 40 , at least one first opening 303 is provided on the heat insulating sleeve 30 , and the first opening 303 extends from the end surface of the heat insulating sleeve 30 close to the handle body 10 along a side close to the light guide beam 20 .
[0055] In this embodiment, the first opening 303 is more suitable for folding the heat insulation sleeve 30. In a specific embodiment, as shown in the attached Figure 4 As shown, the heat insulating sleeve 30 is provided with a first opening 303, and the operator can fold the heat insulating sleeve 30 through the first opening 303; in another specific embodiment, the heat insulating sleeve 30 is provided with two first openings 303, and the two first openings 303 are symmetrically arranged along the radial direction of the heat insulating sleeve 30. In this embodiment, the operator only needs to pull the heat insulating sleeve 30 apart to put the heat insulating sleeve 30 in the second state. Of course, the first openings 303 can also be set to three, four or more than four, but the first openings 303 have a certain width. If too many first openings 303 are set, the heat insulating effect of the heat insulating sleeve 30 will be reduced. In this application, it is preferred to set the first openings 303 to one or two.
[0056] As attached Fig.10 As shown, in this embodiment, the insulation sleeve 30 and the anti-scalding sleeve 40 are integrally formed, and the end of the insulation sleeve 30 away from the handle body 10 has a third state of covering the outer periphery of the second joint 21 and a fourth state of being folded by external force to expose the second joint 21.
[0057] Specifically, in this embodiment, the heat insulation sleeve 30 and the anti-scalding sleeve 40 are integrally molded by silicone injection molding. When the light guide beam 20 and the handle body 10 are assembled, as shown in the attached Fig.12 As shown, first, the second joint 21 is exposed when the heat insulation sleeve 30 is folded, then the first joint 11 is connected to the second joint 21, and finally the heat insulation sleeve 30 is restored so that the heat insulation sleeve 30 covers the outer periphery of the second joint 21 to complete the assembly. The structure of this embodiment is also relatively simple and easy to assemble.
[0058] Similarly, when the heat insulating sleeve 30 and the anti-scalding sleeve 40 are integrally formed, at least one second opening 304 is provided on the heat insulating sleeve 30. The second opening 304 extends from the end surface of the heat insulating sleeve 30 close to the light guide beam 20 along the side close to the handle body 10. The second opening 304 facilitates the operator to fold or restore the heat insulating sleeve 30. The second opening 304 can also be set to two, three or more. Preferably, as shown in the attached Fig.13 As shown, two second openings 304 are provided.
[0059] In addition, when the first opening 303 or the second opening 304 is provided on the insulation sleeve 30, the external air can contact the first joint 11 and the second joint 21 through the first opening 303 or the second opening 304, thereby taking away part of the heat on the first joint 11 and the second joint 21, thereby improving the heat dissipation effect of the first joint 11 and the second joint 21.
[0060] Furthermore, the insulation sleeve 30 is arranged on the periphery of the first joint 11, and the insulation sleeve 30 reciprocates in the direction from the handle body 10 to the light guide beam 20, and the insulation sleeve 30 has a fifth state in which it moves in the direction close to the light guide beam 20 and covers the second joint 21, and a sixth state in which it moves in the direction close to the handle body 10 to expose the second joint 21.
[0061] Specifically, when assembling the handle body 10 and the light guide beam 20, first operate the insulation sleeve 30 to move in a direction close to the handle body 10 and expose the second joint 21, then connect the first joint 11 with the second joint 21, and then operate the insulation sleeve 30 to move in a direction close to the light guide beam 20 so that the insulation sleeve 30 covers the outer periphery of the second joint 21.
[0062] In this embodiment, the insulation sleeve 30 is disposed on the periphery of the first joint 11. Of course, in other embodiments, the insulation sleeve 30 can be disposed on the periphery of the second joint 21; similarly, the insulation sleeve 30 can reciprocate along the direction from the handle body 10 to the light guide beam 20. When the insulation sleeve 30 moves in the direction close to the handle body 10, the insulation sleeve 30 can cover the periphery of the first joint 11. When the insulation sleeve 30 moves in the direction close to the light guide beam 20, the insulation sleeve 30 will gradually move away from the first joint 11 and eventually expose the first joint 11.
[0063] In one embodiment, as shown in the attached Figure 7 To Attachment Fig. 9 As shown, the insulation sleeve 30 includes a flexible telescopic section 31 and a covering section 32. The flexible telescopic section 31 is fixedly sleeved on the outer periphery of the first joint 11, and the covering section 32 is connected to a side of the flexible telescopic section 31 close to the light guide beam 20. The flexible telescopic section 31 is subjected to external force to switch the covering section 32 between the fifth state and the sixth state.
[0064] Specifically, the flexible telescopic section 31 and the anti-scalding sleeve 40 are integrally formed. When assembling the light guide beam 20 and the handle body 10, the flexible telescopic section 31 is first operated to retract so that the covering section 32 is separated from the second joint 21. At this time, the second joint 21 is exposed, and then the second joint 21 is connected to the first joint 11. Then, the flexible telescopic section 31 is operated to recover so that the covering section 32 covers the outer periphery of the second joint 21. It is worth mentioning that in this embodiment, when the flexible telescopic section 31 is retracted, the flexible contraction section and the side of the covering section 32 close to the light guide beam 20 are on the same plane. In addition, in some embodiments, the side of the covering section 32 close to the light guide beam 20 is not in contact with the light guide beam 20 or the second joint 21, so there is a certain gap between the covering section 32 and the second joint 21, and air can take away the heat from the second joint 21 through the gap, thereby improving the heat dissipation effect of the first joint 11 and the second joint 21.
[0065] In one embodiment, as shown in the attached Fig.16 To Attachment Fig.18 As shown, the heat insulating sleeve 30 includes a fixing seat 33 and a shell 34. The fixing seat 33 is fixedly sleeved on the outer periphery of the first joint 11. A slide groove 331 is provided on the fixing seat 33. The shell 34 is slidably connected to the slide groove 331, and the shell 34 slides on the slide groove 331 to switch the shell 34 between the fifth state and the sixth state.
[0066] Specifically, when assembling the handle assembly, first slide the outer shell 34 in a direction close to the handle body 10, and fix the outer shell 34 so that the second joint 21 is exposed, then connect the first joint 11 with the second joint 21, and finally operate the outer shell 34 to slide in a direction close to the light guide beam 20 so that the outer shell 34 covers the outer periphery of the second joint 21.
[0067] In a specific embodiment, a spring 35 is disposed in the slide groove 331, and a protruding section 341 extending into the slide groove 331 is disposed on the housing 34. The protruding section 341 abuts against the spring 35. When the first joint 11 and the second joint 21 need to be assembled, the operator applies force to the housing 34 so that the housing 34 slides in a direction close to the handle body 10. At this time, the protruding section 341 applies force to the spring 35 so that the spring 35 is compressed. After the first joint 11 and the second joint 21 are connected, the external force applied to the housing 34 is removed. At this time, the spring 35 applies elastic force to the protruding section 341 in order to restore, so that the housing 34 slides in a direction close to the light guide beam 20, and finally the housing 34 covers the outer periphery of the second joint 21.
[0068] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0069] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
[0070] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
