Description

Technical Field

[0001] This utility model relates to the field of surgical microscope technology, and more specifically, to a surgical microscope spectral ratio switching device. Background Technology

[0002] Surgical microscope 3D imaging systems utilize a beam-splitting component added to the parallel optical path of the surgical microscope to distribute a portion of the light from the eyepiece's optical path to the 3D imaging optical path. The advantage of this approach is that it retains the eyepiece while acquiring a 3D image, allowing for the choice between performing surgical procedures under the eyepiece or observing the 3D image. The disadvantage is that the limited light energy acquired by the 3D imaging system restricts the quality of the 3D image, such as depth of field and noise level.

[0003] Therefore, some surgical microscopes directly replace the eyepiece with a 3D imaging system, so that all light is used for 3D imaging, thereby obtaining images with relatively large depth of field and relatively low noise. However, this mode of performing surgical operations can only be done by observing 3D images, which loses the possibility of using the eyepiece for observation and confirmation at any time.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-7 As shown, this embodiment provides a surgical microscope beam splitting ratio switching device, including: a rotating component 10, a reflecting mirror 20 and a beam splitter 30. The rotating component 10 is rotatably connected to the microscope and has a connecting part 11 located inside the microscope. The reflecting mirror 20 is fixedly connected to the rotating part, and the beam splitter 30 is fixedly connected to the rotating part. The beam splitting surface of the beam splitter 30 and the reflecting surface of the reflecting mirror 20 are located on the same plane. The rotating component 10 rotates to drive the reflecting mirror 20 and the beam splitter 30 to rotate, thereby selectively allowing light to pass through the beam splitter 30 into the eyepiece assembly and the 3D imaging assembly, or selectively allowing light to pass through the reflecting mirror 20 into the 3D imaging assembly.

[0031] In some embodiments, the rotating member 10 is rotatably connected to the microscope, and the rotating member 10 has a connecting portion 11 located inside the microscope. The reflecting mirror 20 and the beam splitter 30 are both fixedly connected to the rotating portion of the rotating member 10, and the beam splitting surface of the beam splitter 30 and the reflecting surface of the reflecting mirror 20 are on the same plane. By rotating the rotating member 10, the reflecting mirror 20 and the beam splitter 30 can be driven to rotate synchronously, thereby achieving selective distribution of light. Specifically, light can be selectively allowed to pass through the beam splitter 30 into the eyepiece assembly and the 3D imaging assembly, or light can be selectively allowed to pass through the reflecting mirror 20 into only the 3D imaging assembly.

[0032] In this application, medical personnel can selectively use the reflector 20 or the beam splitter 30 by controlling the rotation of the rotating component 10 during surgery. For example, when the eyepiece assembly needs to be used, the medical personnel can control the rotation of the rotating component 10 to allow light to pass through the beam splitter 30. The beam splitter 30 can distribute the light, allowing most of the light to enter the eyepiece assembly and a small portion of the light to enter the 3D imaging assembly. At this time, the medical personnel can use the eyepiece assembly to clearly observe the surgical site, so that they can confirm the surgical site at any time or perform fine operations. Of course, when the 3D imaging assembly needs to be used, the medical personnel can control the rotation of the rotating component 10 to allow light to pass through the reflector 20. The reflector 20 reflects the light so that all the light enters the 3D imaging assembly, thereby enabling the 3D imaging assembly to obtain images with a large depth of field and low noise. This allows the medical personnel to obtain as much information about the surgical site as possible, helping them to observe the surgical site more clearly and improve the accuracy of the surgery.

[0033] It should be noted that the reflector 20 can be a right-angle prism with total internal reflection, a plane reflector 20, or other reflective elements, etc., without limitation; the beam splitter 30 can be a beam splitter prism with a specific ratio, such as 80:20, 75:25, 70:30, etc., without limitation, as long as the light entering the eyepiece assembly after being processed by the beam splitter 30 is greater than the light entering the 3D image assembly.

[0034] For example, when the beam splitting ratio of the beam splitter is 80:20, and the medical staff controls the rotating part 10 to rotate and make the light pass through the beam splitter, a beam splitting mode in which 80% of the light goes to the eyepiece assembly and 20% of the light goes to the 3D imaging assembly can be achieved. When the medical staff controls the rotating part 10 to rotate and make the light pass through the right-angle prism, 100% of the light goes to the 3D imaging assembly can be achieved.

[0035] It is worth mentioning that when the reflector 20 is a right-angle prism with total internal reflection and the beam splitter 30 can be a beam splitter with a specific ratio, the inclined surface (reflecting surface) of the right-angle prism and the light-dispersing film surface (light-splitting surface) of the beam splitter are coplanar.

[0036] According to the surgical microscope beam splitting ratio switching device of this utility model, the rotating component 10 can be rotated to allow medical staff to selectively use the reflecting mirror 20 or the beam splitter 30. When using the beam splitter 30, medical staff can use the eyepiece assembly to observe the surgical site. When using the reflecting mirror 20, medical staff can use the 3D imaging assembly to observe the surgical site. That is, during surgery, medical staff can control the rotation of the rotating component 10 to effectively observe the surgical site using either the eyepiece assembly or the 3D imaging assembly, thereby improving the convenience of observing the surgical site and thus improving the convenience of surgery.

[0037] According to some embodiments of the present invention, the surgical microscope beam splitting ratio switching device further includes a housing 40, which has a receiving cavity suitable for accommodating the reflector 20 and the beam splitter 30. The top wall of the housing 40 is provided with an eyepiece hole 41 communicating with the receiving cavity. The projection of the eyepiece hole 41 in the microscope height direction is located in the reflector 20 or the beam splitter 30. The side wall of the housing 40 is provided with an image hole 42 communicating with the receiving cavity. The projection of the image hole 42 in the length direction of the housing 40 is located in the reflector 20 or the beam splitter 30. The rotating member 10 is rotatably connected to the housing 40.

[0038] In some embodiments, the housing 40 is connected to the microscope. The housing 40 has an internal cavity for housing the reflector 20 and the beam splitter 30. The housing 40 provides a stable installation environment for the reflector 20 and the beam splitter 30, protecting them from interference and damage from the external environment. The eyepiece aperture 41 is located on the top wall of the housing 40 and communicates with the cavity. The eyepiece assembly is located on the top of the housing 40. The projection of the eyepiece aperture 41 in the microscope height direction is located inside the beam splitter 30. Thus, after the light is processed by the beam splitter 30, it can enter the eyepiece assembly through the eyepiece aperture 41 for medical personnel to observe the surgical site.

[0039] The image aperture 42 is located on the side wall of the housing 40 and is also connected to the receiving cavity. The projection of the image aperture 42 in the length direction of the housing 40 is located in the reflector 20 or the beam splitter 30, which ensures that the light processed by the reflector 20 or the beam splitter 30 can enter the 3D image component through the image aperture 42 to realize the acquisition and display of 3D images.

[0040] The rotating component 10 is rotatably connected to the housing 40. The connecting part 11 of the rotating component 10 is located inside the housing 40 and is connected to the reflector 20 and the beam splitter 30 respectively. The rotation of the rotating component 10 can drive the connecting part 11 to rotate, and the rotation of the connecting part 11 can drive the reflector 20 and the beam splitter 30 to rotate, so that medical staff can selectively use the reflector 20 or the beam splitter 30.

[0041] It should be noted that there are two eyepiece holes 41. The projection of the two eyepiece holes 41 in the height direction of the microscope is located in the reflecting mirror 20 or the beam splitter 30. This ensures that the dual-channel optical paths of the left and right eyes of the surgical microscope always pass through the same piece of optical glass, which is beneficial to ensure the optical consistency of the dual-channel optical paths of the left and right eyes of the microscope by controlling the optical processing tolerance.

[0042] According to some embodiments of the present invention, the rotating member 10 rotates and has a first position and a second position. In the first position, light is suitable to enter the eyepiece hole 41 and the image hole 42 through the beam splitter 30. In the second position, light enters the image hole 42 through the reflector 20.

[0043] Understandably, medical personnel can control the rotation of the rotating component 10 to switch between a first position and a second position. In the first position, the microscope is only used with the beam splitter 30. At this time, light can pass through the beam splitter 30, and under the processing of the beam splitter 30, most of the light can enter the eyepiece assembly through the eyepiece hole 41, and a small part of the light can enter the 3D imaging assembly through the image hole 42. In the second position, the microscope is only used with the reflecting mirror 20. At this time, the light passes through the reflecting mirror 20, and the reflecting mirror 20 reflects all the light and causes all the light to enter the 3D imaging assembly through the image hole 42.

[0044] According to some embodiments of the present invention, a rotating hole is provided on one side wall of the housing 40 in the width direction, and two opposing limiting holes are provided on the inner peripheral wall of the rotating hole. The rotating member 10 is rotatably disposed in the rotating hole, and two opposing limiting blocks 12 are provided on the outer peripheral wall of the rotating member 10. The two limiting blocks 12 can be selectively received in the two limiting holes to fix the rotating member 10 in a first position or a second position.

[0045] It is understood that the rotating part 10 is rotatably disposed in the rotating hole. When the rotating part 10 rotates to the point where the two limiting blocks 12 are respectively aligned with the two limiting holes, the two limiting blocks 12 are respectively housed in the two limiting holes. The inner peripheral wall of the limiting hole can restrict the outer peripheral wall of the limiting block 12, thereby preventing the rotating part 10 from rotating accidentally relative to the housing 40, thus ensuring that medical personnel can stably use the reflector 20 or the beam splitter 30.

[0046] It is worth mentioning that the inner peripheral wall of the rotating hole is provided with two opposing limiting holes, that is, the line connecting the centers of the two limiting holes passes through the center of the rotating hole. When using the beam splitter 30 or the reflector 20, the rotating member 10 needs to rotate by 180° (the beam splitting surface of the beam splitter 30 and the reflecting surface of the reflector 20 are located on the same plane, so that when it is necessary to select the use of the beam splitter 30 or the reflector 20, the rotating member 10 needs to rotate 180°). Thus, through the above arrangement, each time the rotating member 10 rotates 180°, the two limiting blocks 12 can be respectively accommodated in the two limiting holes.

[0047] According to some embodiments of the present invention, the rotating member 10 is provided with two movable grooves extending radially, and a reset member 13 is provided in each of the two movable grooves. Two limiting blocks 12 are respectively connected to the two reset members 13. The limiting blocks 12 can be selectively received in the movable grooves or protrude from the movable grooves. The reset members 13 are adapted to drive the limiting blocks 12 to protrude from the movable grooves.

[0048] In some embodiments, the inner peripheral wall of the movable groove can restrict at least a portion of the outer peripheral wall of the limiting block 12, so that the limiting block 12 can move stably along the extension direction of the movable groove, thereby allowing the limiting block 12 to move stably along the radial direction of the rotating member 10 and be received in the movable groove or protrude from the movable groove.

[0049] A reset member 13 is provided in the movable groove. When the rotating member 10 rotates and the limiting block 12 is not aligned with the limiting groove, the inner peripheral wall of the rotating hole presses against the limiting block 12 and causes the limiting block 12 to press against the reset member 13, so that the limiting block 12 can be accommodated in the movable groove. When the limiting block 12 is aligned with the limiting groove, the reset force of the reset member 13 drives the limiting block 12 to move and protrude out of the movable groove. At this time, part of the limiting block 12 can be accommodated in the limiting groove, thereby fixing the relative position of the rotating member 10 and the housing 40, so that medical staff can stably use the reflector 20 or the beam splitter 30.

[0050] It is worth mentioning that, since the reset component 13 drives the limiting block 12 to protrude out of the movable groove, when the rotating component 10 rotates to the position of the limiting hole, the limiting block 12 will automatically spring into the limiting hole due to the action of the reset component 13, producing a clear "click" sound and a change in resistance. Medical staff can clearly perceive whether the rotating component 10 has reached the designated position through hearing and touch, which provides a good operating feel and improves the accuracy and convenience of operation.

[0051] According to some embodiments of the present invention, the two side walls of the limiting groove in the circumferential direction are respectively inclined to form a first guide surface, and the two side walls of the limiting block 12 in the circumferential direction are respectively inclined to form a second guide surface 121. The first guide surface is adapted to cooperate with the second guide surface 121.

[0052] It is understandable that when the limiting block 12 is housed in the limiting groove and the rotation of the rotating member 10 needs to be controlled, the first guide surface and the second guide surface 121 can cooperate with each other, so that the limiting block 12 can be moved more easily and housed in the movable groove. Thus, the rotation of the rotating member 10 is made more convenient through the above-mentioned arrangement, thereby improving the convenience of switching the rotating member 10 between the first position and the second position.

[0053] According to some embodiments of the present invention, the reflector 20 and the beam splitter 30 are connected to each other, and the reflector 20 and the beam splitter 30 are respectively bonded to the connecting part 11.

[0054] In some embodiments, the reflector 20 and the beam splitter 30 are not connected to each other, and the reflector 20 and the beam splitter 30 are respectively connected to the connecting part 11; in other embodiments, the reflector 20 and the beam splitter 30 are connected to each other. In this case, when connecting the reflector 20, the beam splitter 30 and the connecting part 11, it is possible to avoid sequentially gluing the reflector 20 and the beam splitter 30 to the connecting part 11, thereby improving the connection efficiency of the reflector 20, the beam splitter 30 and the connecting part 11, and thus improving the production efficiency of the surgical microscope beam splitting ratio switching device.

[0055] According to some embodiments of the present invention, the reflecting surface of the reflector 20 includes a reflecting area 21 and a connecting area 22. The reflecting area 21 is adapted to reflect light, and the connecting area 22 is adapted to be directly opposite to and connected to the beam splitter surface of the beam splitter 30.

[0056] In some embodiments, the beam-splitting surface of the beam splitter 30 is directly opposite to and connected to the connection area 22, thereby increasing the connection area between the beam splitter 30 and the reflector 20 and improving the connection stability between the beam splitter 30 and the reflector 20. At the same time, it can make the volume of the beam splitter 30 and the reflector 20 smaller after they are connected.

[0057] In some specific embodiments, the inclined surface of the right-angle prism is a reflective surface, which includes a reflective area 21 and a connecting area 22. The inclined surface of the beam-splitting prism is a beam-splitting surface, which is directly opposite and connected to the connecting area 22. This increases the connection area between the right-angle prism and the beam-splitting prism, thereby improving the connection stability. Moreover, the above arrangement also allows for a smaller overall volume after the right-angle prism and the beam-splitting prism are connected, enabling a smaller housing 40 and consequently a smaller overall size for the surgical microscope beam-splitting ratio switching device.

[0058] According to some embodiments of the present invention, the intersection of the reflective area 21 and the connecting area 22 is constructed as a connecting axis. The projection of the connecting axis in the width direction of the housing 40 is located within the rotating member 10. The vertices of the reflector 20 and the beam splitter 30 away from the connecting axis are both chamfered.

[0059] In some embodiments, the extension line of the connecting axis passes through the axis of the rotating member 10. Thus, by chamfering the vertices of the reflector 20 and the beam splitter 30 away from the connecting axis, the rotation radius of the component after the reflector 20 and the beam splitter 30 are connected is smaller, thereby making the fit between the component and the housing 40 more compact, and thus the volume of the housing 40 can be further reduced.

[0060] It should be noted that the vertices of both the reflector 20 and the beam splitter 30 away from the connecting axis are chamfered. This also prevents the components from having sharp corners, thus avoiding scratches to the assembly personnel when assembling the beam splitter switching device of the surgical microscope. At the same time, it can reduce stress concentration when the reflector 20 and / or the beam splitter 30 collide, reducing the risk of breakage of the reflector 20 and / or the beam splitter 30.

[0061] According to some embodiments of the present invention, the connecting part 11 is provided with a first snap-fit ​​part, and the reflector 20 and / or beam splitter 30 is provided with a second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part cooperate to connect the reflector 20 and / or beam splitter 30 to the connecting part 11.

[0062] In some embodiments, one of the first and second snap-fit ​​portions is configured as a snap-fit ​​block, and the other of the first and second snap-fit ​​portions is configured as a snap-fit ​​groove. The snap-fit ​​block is received in the snap-fit ​​groove to connect the reflector 20 and / or the beam splitter 30 to the connecting portion 11.

[0063] In other embodiments, the reflector 20 may have a second latching portion, and the connecting portion 11 may have a first latching portion corresponding to the second latching portion; alternatively, the beam splitter 30 may have a second latching portion, and the connecting portion 11 may have a first latching portion corresponding to the second latching portion; or both the reflector 20 and the beam splitter 30 may have second latching portions, and the connecting portion 11 may have two first latching portions, which correspond to the second latching portions on the reflector 20 and the beam splitter 30, respectively. No limitation is imposed here.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
