In some embodiments, the ophthalmoscope of the surgical microscope is provided independently of the surgical microscope. When the operation microscope is switched from the anterior segment mode to the posterior segment mode, a lens needs to be added on the operation microscope to change the focusing plane, and a group of lenses needs to be added for adjusting the focal distance. Therefore, with this surgical microscope, when the posterior segment mode of the eye is enabled during surgery, an operator is required to manually install the ophthalmoscope in the field into the main observation optical path of the surgical microscope; when the anterior segment mode is started in the operation process, the operator needs to remove the ophthalmoscope from the main observation light path of the operation microscope so as to perform the operation. The operation microscope is very troublesome to operate when the operation microscope is switched between the anterior segment mode and the posterior segment mode, and the defect is more obvious particularly in a clinical operation scene.

The disclosed embodiment provides an improved ophthalmoscope module, which can connect the ophthalmoscope of a surgical microscope and the ophthalmoscope module of the surgical microscope through a connecting piece. The improved ophthalmoscope module is used in an operating microscope, and if an eye posterior segment mode is required in the operating process, the ophthalmoscope is unfolded through the connecting piece and moved into a main observation light path of the operating microscope; similarly, if the eye anterior segment mode is required to be switched in the operation process, the ophthalmoscope is moved out of the main observation light path of the operation microscope through the connecting piece and is stored. The operation microscope is very convenient to operate when the operation microscope is switched between the anterior segment mode and the posterior segment mode, and the advantage is more prominent particularly in a clinical operation scene.

As shown in fig. 1 to 4, the present embodiment provides an eyeglasses module, comprising a focusing assembly 1, a connecting member 2 and an eyeglasses 3, wherein the connecting member 2 is slidably connected to the focusing assembly 1 along a first direction; the ophthalmoscope 3 is connected with the connecting piece 2; the connecting piece 2 slides relative to the focusing assembly 1 along a first direction to an unfolded state enabling the ophthalmoscope 3 to be far away from the focusing assembly 1 and a retracted state enabling the ophthalmoscope 3 to be close to the focusing assembly 1; in the accommodated state, the ophthalmoscope 3 is fastened to the focusing assembly 1.

In the embodiment of the present disclosure, by providing the connecting member 2, the ophthalmoscope 3 of the operation microscope and the ophthalmoscope module of the operation microscope can be connected together, and by simply operating the connecting member 2, the ophthalmoscope 3 of the operation microscope can be conveniently and rapidly placed in the storage state and the expansion state. When the ophthalmoscope 3 is placed in the unfolding state, the ophthalmoscope 3 is located the position of keeping away from the focusing assembly 1, and when the ophthalmoscope 3 is placed in the accommodating state, the ophthalmoscope 3 is located the position close to the focusing assembly 1 and is buckled in the focusing assembly 1.

Illustratively, as shown in FIG. 1, the attachment member 2 is slidably coupled to the focus assembly 1 in a first direction, and the ophthalmoscope 3 is coupled to the attachment member 2. During the use, operating personnel only need operation connecting piece 2 to remove along first direction, can realize the conversion of 3 states of ophthalmoscope, and the operation is more convenient. Meanwhile, the ophthalmoscope 3 placed in the storage state can be buckled on the focusing assembly 1, so that the occupation of the operation space by the ophthalmoscope 3 and the connecting piece 2 in the storage state can be reduced as much as possible, and the operation is more favorably developed. In addition, if the ophthalmoscope 3 is connected with the focusing assembly 1 by the hinge, dead angles exist in the disinfection link of the ophthalmoscope module, and the sterile state of the ophthalmoscope module in the operation cannot be ensured, so that the operation safety is low. And the ophthalmoscope 3 replaces hinged joint with the focusing assembly 1 through the connecting piece 2 in a sliding connection manner, so that the use of hinges can be reduced, dead angles of the ophthalmoscope module can be reduced or even eliminated in a disinfection link, the sterility of the ophthalmoscope module in an operation can be effectively ensured, and the operation safety can be improved.

In the present disclosed embodiment, the first direction may be a direction inclined rearward and upward (rearward and upward) and a direction inclined forward and downward (forward and downward) with respect to the focus adjustment assembly 1 as shown in fig. 1. By arranging the first direction obliquely, the size of the ophthalmoscope module is advantageously reduced. Further, in order to realize the limit of the adjustment of the connecting piece 2 relative to the focusing assembly 1 along the first direction, an upper limit and a lower limit may be provided on the connecting piece 2 or the focusing assembly 1. For example, two limits, an upper limit and a lower limit, may be provided on the connecting member 2. Alternatively, for example, two limits, an upper limit and a lower limit, may be provided on the focus adjustment assembly 1. Through setting up spacing and lower spacing, in the use, the user need not further manual regulation connecting piece 2's position, can be accurate with connecting piece 2 spacing in preset position. Namely, the upper limit and the lower limit are arranged, so that the adjustment is more convenient and faster, and the positioning is more accurate.

In the embodiment of the present disclosure, the connecting member 2 may be disposed at the rear end of the focusing assembly 1 (i.e., the end far away from the main surgeon in the clinical operation scene) to reduce the influence of the connecting member 2 on the focusing assembly 1. In the present disclosed embodiment, in the case where the ophthalmoscope 3 is placed in the accommodated state, the upper limit work is performed for limiting the attachment 2 to a position located at the upper rear of the focus adjustment assembly 1 as shown in fig. 5. In the case where the ophthalmoscope 3 is placed in the unfolded state, the lower limit works to limit the link 2 to a position located forwardly and downwardly of the focusing assembly 1 as shown in fig. 6 to 8.

In this embodiment, the connection member 2 includes a first connection rod 21, an axis of the first connection rod 21 extends in a first direction, and the first connection rod 21 is provided with a sliding end 211 and a first connection end 212. The sliding end 211 is arranged for realizing the sliding connection of the connecting piece 2 and the focusing assembly 1. By providing the first connection end 212, a connection to the ophthalmoscope 3 is made. For example, the upper limit and the lower limit may be both disposed on the first connecting rod 21, and in the sliding process of the first connecting rod 21, the limit is realized by abutting against the focusing assembly 1.

In this embodiment, as shown in fig. 2 and 3, a sliding hole 11 is disposed on a side surface of the focusing assembly 1, which is slidably connected to the connecting member 2, an axis of the sliding hole 11 extends along the first direction, and the sliding end 211 is slidably disposed in the sliding hole 11. Adjustment of the ophthalmoscope 3 in the first direction is achieved during sliding of the sliding end 211 along the sliding aperture 11. In an embodiment of the present disclosure, the first connecting rod 21 may be a single connecting rod (hereinafter referred to as a single connecting rod), and the single connecting rod may be slidably inserted into one or more sliding holes 11 arranged along the first direction (i.e., one or more sliding holes with coincident axes), so as to ensure smooth and smooth sliding. Alternatively, in other embodiments of the present disclosure, as shown in fig. 2, the first connecting rod 21 may also be two connecting rods (hereinafter referred to as a double connecting rod) or more connecting rods (hereinafter referred to as a multi-connecting rod) arranged in parallel, and each of the connecting rods may be slidably inserted into one or more sliding holes 11 arranged along the first direction (i.e., one or more sliding holes with coincident axes), so as to ensure smooth sliding.

In the disclosed embodiments, the ophthalmoscope module can be further modified to meet the corresponding disinfection requirements, taking into account the need for a sterile environment for the surgical procedure. Illustratively, to enable the ophthalmoscope module to better adapt to the disinfection environment, the inner wall of the slide hole 11 is provided with a guide groove 111 extending axially along the slide hole. Through setting up guiding gutter 111 for the residual liquid after the disinfection can flow out through guiding gutter 111, is favorable to the drying after the disinfection of ophthalmoscope module, can avoid secondary pollution on the one hand effectively, and on the other hand can also avoid remaining the corruption of liquid to equipment effectively. Further, the inner wall of the slide hole 11 may be provided with one or more flow guide grooves 111, and the flow guide grooves 111 are uniformly arranged along the circumferential direction of the slide hole 11 at intervals, so that the flow guide effect on the residual disinfectant can be improved.

In the embodiment of the present disclosure, in order to provide the sliding hole 11, one or more mounting protrusions 12 may be disposed on the focusing assembly 1, and the sliding hole 11 is disposed on each of the one or more mounting protrusions 12. In some embodiments, in the case that the first connecting rod 21 is a single connecting rod, only one mounting protrusion 12 may be disposed on the focusing assembly 1, a sliding hole 11 may be formed on the mounting protrusion 12, and the first connecting rod 21 is slidably disposed through the sliding hole 11. Or, in some embodiments, when the first connecting rod 21 is a single connecting rod, the focusing assembly 1 may also be provided with a plurality of mounting protrusions 12 arranged along the first direction, the mounting protrusions 12 are provided with sliding holes 11 whose axes are coincident and extend along the first direction, and the first connecting rod 21 is slidably disposed through the sliding holes 11. Similarly, in other embodiments, in the case that the first connecting rod 21 is a double connecting rod, two rows of mounting protrusions 12 corresponding to the double connecting rods may be provided, each row of mounting protrusions 12 may include one or more mounting protrusions 12 arranged along the first direction, and the mounting protrusions 12 are provided with sliding holes 11 having axes coinciding with each other and extending along the first direction, so that the corresponding connecting rods are slidably connected therein. In the disclosed embodiment, the mounting protrusions 12 in the same row of mounting protrusions 12 may be spaced apart along the first direction. This arrangement makes it possible to more stably install the first connecting rod 21, and to ensure the thoroughness of sterilization by disposing the plurality of installation protrusions 12 at intervals.

It should be understood that in the disclosed embodiment, the mounting projections 12 are spaced apart for thorough sterilization. However, the installation protrusions 12 are arranged at intervals, which may cause disinfectant to remain, so that the corresponding diversion trench 111 is further added when the sliding hole 11 is opened in the embodiment of the present disclosure, so as to facilitate the derivation of the remaining disinfectant.

The second connecting rod 22 is arranged, so that when the first connecting rod 21 is located at the position above the rear portion of the focusing assembly 1, the second connecting rod 22 can be rotated to enable the ophthalmoscope 3 to be further buckled at the bottom end of the focusing assembly 1, and therefore the occupation of the peripheral space when the ophthalmoscope 3 is placed in the accommodating state is further reduced.

In the embodiment of the disclosure, to connect the second connecting rod 22 and the first connecting rod 21, one of the rotating end 221 and the first connecting end 212 may be provided with a rotating shaft 2121, and the other may be provided with a sleeve 2211 sleeved outside the rotating shaft 2121, wherein the extending direction of the rotating shaft 2121 is perpendicular to the first direction. It is understood that, for example, the extending direction of the rotating shaft 2121 may be the left-right direction as shown in fig. 1. When the sleeve 2211 and the rotating shaft 2121 rotate relatively, the second connecting rod 22 can be driven to rotate relative to the first connecting rod 21, so that the position of the ophthalmoscope 3 can be changed. Illustratively, the first connection end 212 is provided with the rotation shaft 2121, and the rotation end 221 is provided with the sleeve 2211, in the case that the first connection rod 21 is a double connection rod, the sleeve 2211 is sandwiched between two connection rods of the first connection rod 21, so that the rotation end 221 can be effectively prevented from slipping off in the left-right direction.

In the disclosed embodiment, to facilitate the connection between the rotating end 221 and the first connecting end 212 to dry quickly after sterilization, the sleeve 2211 is provided with axial guiding grooves 2212 and/or radial guiding grooves 2213 communicated with the rotating shaft 2121. By providing the axial guiding groove 2212 and/or the radial guiding groove 2213, the residual disinfectant can be easily and rapidly discharged along the axial direction and/or the radial direction of the rotating shaft 2121, and the residual disinfectant at the connection position of the rotating end 221 and the first connecting end 212 is avoided.

In this embodiment, the arrangement of the axial guiding slot 2212 is similar to that of the guiding slot 111, and is not described herein again. It should be noted that, in the case that the sleeve 2211 is provided with the axial diversion groove 2212 communicated with the rotating shaft 2121, a drainage port communicated with the axial diversion groove 2212 may be correspondingly arranged at the first connection end 212 of the first connection rod 21, so that the liquid in the axial diversion groove 2212 can smoothly flow out.

Further, in the case where the sleeve 2211 is provided with the radial guide grooves 2213, the extension angle of the radial guide grooves 2213 in the circumferential direction of the sleeve 2211 is 10 ° to 180 °. It should be noted that, by setting the radial diversion grooves 2213 to different extension angles, different radial diversion effects can be achieved. Illustratively, the radial guide grooves 2213 at the two ends of the sleeve 2211 may extend along the circumferential direction of the sleeve 2211 by an angle of 10 °, so as to achieve a certain flow guiding effect and ensure the stability of the installation of the sleeve 2211. Illustratively, the radial guide grooves 2213 in the middle of the sleeve 2211 may extend at an angle of 180 ° in the circumferential direction of the sleeve 2211 to ensure a good radial guide effect, and the middle of the sleeve 2211 is provided with a plurality of radial guide grooves 2213 to perform radial guide more quickly and thoroughly.

It should be noted that the first connecting rod 21 or the second connecting rod 22 is provided with an overturn limiting device, and the overturn limiting device is used for limiting the position of the second connecting rod 22 relative to the first connecting rod 21 when the ophthalmoscope 3 is placed in the unfolded state. It can be understood that, when the overturn limiting operation is performed, the position of the second connecting rod 22 relative to the first connecting rod 21 can be accurately positioned without further adjustment by an operator, which is beneficial to simplifying the operation of rapidly switching the ophthalmoscope 3 from the storage state to the unfolding state.

In the embodiment of the present disclosure, the ophthalmoscope 3 is detachably connected to the second connection end 222, and the ophthalmoscope 3 is detachably connected, so that the operator can conveniently replace different kinds of ophthalmoscopes 3 according to the difference of objects (such as children and adults) to be observed in the actual operation scene.

Further, in order to limit and fix the ophthalmoscope 3 in the accommodated state relative to the focusing assembly 1, one of the second connecting rod 22 and the focusing assembly 1 is provided with a first connecting piece 223, and the other is provided with a second connecting piece. The ophthalmoscope 3 is limited relative to the focusing assembly 1 in the accommodating state, so that the ophthalmoscope 3 in the accommodating state can not interfere with the use or movement of the focusing assembly 1; further fix through carrying out spacing ophthalmoscope 3 for the connection of ophthalmoscope 3 for focusing subassembly 1 is more reliable, and then makes focusing subassembly 1 more convenient in the use or removal process. Exemplarily, under the condition that the ophthalmoscope 3 is placed in the storage state, the first connecting member 223 can be matched with the second connecting member to enable the ophthalmoscope 3 to be buckled at the bottom of the focusing assembly 1 in the storage state, so that the second connecting rod 22 is limited and fixed relative to the focusing assembly 1, and further, the ophthalmoscope 3 is limited and fixed relative to the focusing assembly 1. In the embodiment of the present disclosure, the first connecting member 223 can be magnetically attracted to the second connecting member without a complex structure, and the connection and disconnection are both convenient and reliable.

In the embodiment of the present disclosure, in order to realize the limitation of the ophthalmoscope module sliding along the second direction relative to the main light path imaging illumination module 100, a front limitation and a rear limitation may be disposed on the ophthalmoscope module or the main light path imaging illumination module 100. For example, anterior and posterior limits may be provided on the ophthalmoscope module. Alternatively, for example, a front limit and a rear limit may be provided on the main light path imaging illumination module 100. The anterior limit is used to limit the position of the ophthalmoscope module at the anterior end (i.e., the end near the primary surgeon and patient during surgery) relative to the primary optical path imaging illumination module 100; the posterior limit serves to limit the position of the ophthalmoscope module at the posterior end (i.e., the end away from the primary surgeon and patient during surgery) relative to the primary light path imaging illumination module 100.

In the embodiment of the present disclosure, when the surgical microscope is in the anterior segment mode, the focusing assembly 1 and the ophthalmoscope 3 do not need to work, and as shown in fig. 5, the ophthalmoscope 3 in the ophthalmoscope module needs to be slid to the storage state through the connecting member 2, and at the same time, the ophthalmoscope module needs to be slid to the storage position away from the observation port 110.

In the embodiment of the present disclosure, in the case that the operating microscope is switched to the posterior segment mode, the focusing assembly 1 and the ophthalmoscope 3 need to work, as shown in fig. 5 to 8, the operator can pull down the first connecting rod 21 in the direction of the lower arrow in fig. 5, so that the connecting rod 2 is slid downward as a whole until the lower limit is reached. Meanwhile, when the first connecting rod 21 is pulled down, the first connecting piece 223 on the second connecting rod 22 is disconnected from the second connecting piece, and the second connecting rod 22 is turned downwards along the direction of the arrow below in fig. 6 under the action of gravity until the second connecting rod is turned to the turning limit operation, so that the ophthalmoscope module is placed in the unfolded state shown in fig. 7. Since the ophthalmoscope 3 and the focusing assembly 1 need to be moved into the main observation optical path of the main optical path imaging and illuminating module 100 in the posterior segment mode, the ophthalmoscope module needs to be slid forward along the direction of the lower arrow in fig. 7 until the ophthalmoscope module slides to the front limit position for working, so that the surgical microscope is placed in the posterior segment mode as shown in fig. 8. At this time, the doctor can perform operation observation through the observation port 110, the focusing assembly 1 and the ophthalmoscope 3 in sequence along the main observation optical path. When the ophthalmoscope module is not needed to be used, the operation process can be referred to, and the ophthalmoscope module can be stored in the state shown in fig. 5 according to the reverse order, which is not described again in the embodiment of the present disclosure.
