Abstract
Description
[0001] This invention is a divisional application of application number 202011634819.5, filed on December 31, 2020, entitled "A Surgical Microscope Device". Technical Field
[0002] This invention relates to the field of microscopy, and more particularly to a surgical microscope apparatus. Background Technology
[0003] When a dentist uses a surgical microscope to examine a patient's teeth, the patient is lying down. The dentist will observe the teeth from multiple angles, such as the left and right sides, as needed. However, existing surgical microscopes have the following design flaws: 1. Each time the dentist examines teeth at different angles, the microscope position needs to be changed, resulting in multiple changes in the dentist's observation posture; 2. Although existing technology allows for multi-angle observation through multi-angle microscope adjustments, when the dentist moves horizontally to one side of the patient, the microscope also rotates, changing its position and causing the target area to be outside the objective lens's observation range. The dentist needs to readjust the microscope, resulting in limited flexibility in adjustment and a poor viewing experience; 3. When operating on the patient's head, the dentist needs to lean forward to observe through the eyepiece, and the handle is close to the dentist's body, requiring a significant arm bend when holding the handle, which can easily lead to dentist fatigue and a poor overall experience.
[0004] Therefore, it is necessary to provide a new technical solution. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0023] like Figures 1 to 5 As shown, the surgical microscope of the present invention includes a support 1, a first rotating arm 2, a microscope body 3, a first rotating assembly 10, a second rotating assembly 220, a third rotating assembly 324, a first locking knob 16, a second locking knob 212, and a third locking knob 322. One end of the first rotating arm 2 is rotatably connected to the support 1, and the other end of the first rotating arm 2 is connected to the microscope body 3. The first rotating arm 2 rotates about its central axis, driving the microscope body 3 to rotate. The axis 4 of the first rotating arm's rotation is coaxial with the principal optical axis 5 of the microscope body 3. In another embodiment, the axis 4 of the first rotating arm's rotation is substantially coaxial with the principal optical axis 5 of the microscope body 3.
[0024] like Figures 6 to 8As shown, the first rotating arm 2 includes a first cylindrical structure 21 and a second cylindrical structure 22 connected to the first cylindrical structure 21. One end of the first cylindrical structure 21 has an opening, and the other end of the first cylindrical structure 21 is integrally connected to the second cylindrical structure 22. The rotation axis of the first rotating assembly is coaxial with the central axis of the first cylindrical structure 21. The central axis of the first cylindrical structure 21 is perpendicular to the central axis of the second cylindrical structure 22, and the central axis of the first cylindrical structure 21 is coaxial with the central axis of the first rotating arm 2. When the first cylindrical structure 21 is rotated, the operator's field of vision remains unchanged, only the angle of vision changes. In one embodiment, the axis 4 of the rotation axis of the first rotating arm is vertically arranged, and the principal optical axis 5 of the lens body 3 is nearly coaxial with the axis 4 of the rotation axis of the first rotating arm, meaning that the principal optical axis 5 is parallel to but does not coincide with the axis of the rotation axis of the first rotating arm, and the distance between the principal optical axis 5 of the lens body and the axis of the rotation axis of the first rotating arm is greater than 0 and less than or equal to 30 mm. In another embodiment, the principal optical axis 5 of the mirror body 3 is approximately coaxial with the axis of rotation of the first rotating arm, meaning that the principal optical axis 5 intersects the axis of rotation of the first rotating arm, and the angle between the principal optical axis 5 of the mirror body and the axis of rotation of the first rotating arm is greater than 0° and less than or equal to 10°. When the distance between the principal optical axis 5 of the mirror body and the axis of rotation of the first rotating arm is greater than 0 and less than or equal to 30mm, or when the angle between the principal optical axis 5 of the mirror body and the axis of rotation of the first rotating arm is greater than 0° and less than or equal to 10°, the operator's field of view changes when rotating the first rotating arm, but this does not affect the observation effect.
[0025] Continue reading Figures 1 to 5 , Figure 1 and Figure 2 The arrow shown indicates the direction of rotation of the first rotating arm. Figure 3 and Figure 5 The middle arrows indicate the direction of rotation of the microscope body driven by the first rotating arm. In this invention, the axis 4 of the first rotating arm 2's rotation shaft is coaxial with the main optical axis 5 of the lens. Thus, when the first rotating arm 2 rotates, the field of view of the lens 223 only changes angle, not position. This eliminates the need for repeated adjustments to the microscope's focal length when changing the lens 223's angle, significantly improving work efficiency. Furthermore, this invention employs high-precision composite bearings 13 and needle roller bearings 14, ensuring high coaxiality during rotation adjustments, minimal image jitter, and smooth rotational adjustment.
[0026] like Figure 7 and Figure 8As shown, the first rotating assembly 10 includes a connecting rod seat 11, a connecting shaft 211, a combined bearing 13, a needle roller bearing 14, a first clamp 15, and a first locking knob 16. The connecting rod seat 11 is fixedly connected to the bracket 1. The connecting rod seat 11 has an inner cavity and a through hole communicating with the inner cavity, through which the first locking knob 16 passes. A boss 12 is formed on the inner cavity wall, and the through hole is opened on one side of the connecting rod seat 11. The connecting shaft 211 is accommodated in the inner cavity, and both ends of the connecting shaft 211 extend out of the inner cavity. One end of the connecting shaft 211 is fixedly connected to the first rotating arm 2 through an opening, and the other end of the connecting shaft 211 has a bearing groove (not shown) near the outer end. The needle roller bearing 14 is sleeved on the connecting shaft 211 and fixed in the inner cavity, and the needle roller bearing 14 is near one end of the connecting shaft 211. The combined bearing 13 is sleeved on the connecting shaft 211 and fixed in the inner cavity, and the combined bearing is located outside the bearing groove. The first clamp 15 is sleeved on the connecting shaft 211, and the first clamp 15 is located between the needle roller bearing 14 and the combined bearing 13. The first clamp 15 is located at the through hole and is close to the combined bearing 13. A receiving groove is formed between the first clamp 15 and the needle roller bearing 14, and the boss 12 is engaged in the receiving groove; the boss 12 can prevent the first clamp 15 from moving on the connecting shaft 211.
[0027] The first locking knob 16 is a damping knob. It is configured to engage or disengage from the first clamp 15 via a locking rod 19 from the outside of the connecting rod seat to lock or unlock the first rotating arm. The connecting shaft 211 is configured to rotate about the central axis of the first cylindrical structure 21 within the combined bearing 13 and the needle roller bearing 14. The connecting shaft 211 drives the mirror body 3 to rotate. When rotation of the connecting shaft 211 is prevented, the locking rod of the first locking knob 16 engages with the first clamp 15, locking the connecting shaft 211. The first rotating assembly 10 also includes a threaded ring 18, which is fixedly sleeved on the other end of the connecting shaft 211 and is close to the combined bearing 13.
[0028] In existing technology, when the first locking knob locks the connecting shaft via the locking rod, the locking rod directly abuts against the connecting shaft. This results in dents at the contact point between the connecting shaft and the locking rod of the first locking knob, leading to an unstable lock. Therefore, this invention provides a first clamp 15 fitted onto the connecting shaft 211. When the first locking knob locks the connecting shaft via the locking rod, the locking rod directly abuts against the first clamp 15, causing the first clamp 15 to grip the connecting shaft 211 tightly, making the lock more secure and preventing damage to the connecting shaft. This improves rotational accuracy and extends the microscope's lifespan. The first rotating assembly of this invention uses a high-precision composite bearing 13 and a needle roller bearing 14. This ensures high coaxiality between the axis of the first rotating assembly and the main optical axis of the lens during rotation adjustment, resulting in minimal microscope image jitter and smooth rotational adjustment.
[0029] like Figures 6 to 9 As shown, the mirror body 3 includes a second rotating arm 31 and a mirror body 32. One end of the second rotating arm 31 is rotatably connected to the other end of the first rotating arm 2. Specifically, one end of the second rotating arm 31 is rotatably connected to one end of the second cylindrical structure 22, and the other end of the second rotating arm 31 is fixedly connected to the mirror body 32. The second rotating arm 31 is configured to swing about the central axis of the second cylindrical structure 22 as the pivot, and the second rotating arm 31 drives the mirror body 32 to swing for the first time.
[0030] like Figure 9 As shown, the second rotating assembly 220 is housed within the second cylindrical structure 22. The second rotating assembly 220 includes a balance shaft 221, a bearing 22, a worm gear 223, a worm 224, and a coil spring 225 that can provide restoring force.
[0031] One end of the balance shaft 221 is fixedly connected to one end of the second rotating arm 31, and the axial direction of the balance shaft 221 is coaxial with the central axis of the second cylindrical structure 22. Bearings 22 are respectively sleeved on both ends of the balance shaft 221. The inner side of the coil spring 225 is fixedly sleeved on the balance shaft 221, and the outer side of the coil spring 225 is fixedly connected to the worm gear 223. The worm gear 223 is sleeved on the balance shaft 221 and located outside the coil spring 225. The worm 224 meshes with the worm gear 223 for transmission. Rotating the worm 224 causes the worm gear 223 to rotate around the balance shaft 221 with the central axis as its axis. The worm gear 223 causes the outer side of the coil spring 225 to rotate to adjust the torque of the coil spring 225. The balance shaft 221 is configured to rotate, thereby driving the second connecting arm 31 to rotate. When the balance shaft 221 rotates, it drives the second connecting arm 31 to rotate, causing the lens body 32 to swing in a first manner, generating a first torque. Simultaneously, the balance shaft 221 causes the inner side of the coil spring 225 to reverse, causing the coil spring 225 to be subjected to force and generate a second torque. The second torque is opposite in direction to the first torque, thus counteracting the first torque. The second rotating arm 31 of this invention swings back and forth at 40° around the central axis of the balance shaft 221. To balance the torque generated by the lens 323, a coil spring 225 is added to the balance shaft 221 to balance the torque generated by the swing of the lens 323. This allows the user to swing the lens 323 more easily without having to exert force to counteract the torque generated by the swing of the lens 323. When the user adds accessories that change the center of gravity of the lens, the torque of the coil spring 225 can be changed through a worm gear mechanism to rebalance the new lens weight. The second locking knob 212 is disposed on the first rotating arm 2. The second locking knob 212 is configured to lock the rotation of the second rotating arm 31 and release the lock of the second rotating arm 31.
[0032] The mirror body 32 includes an eyepiece observation assembly 321, a third rotation assembly 324, and a lens 323.
[0033] like Figure 10 and Figure 11As shown, the third rotating assembly 324 includes a fixed base 3223, a rotating base 3241, a connecting base 3242, a pressure ring 3224, and a second clamp 3222. The other end of the second rotating arm 31 is fixed to the upper side of the fixed base 3223. Along the horizontal observation direction of the eyepiece, the eyepiece observation assembly 321, the fixed base 3223, and the rotating base 3241 are rotatably connected in sequence. The pressure ring 3224 is fitted inside the fixed base 3223, and the second clamp 3222 is fitted outside the pressure ring 3224. The connecting base 3242 is fixedly connected to the lower side of the rotating base 3241, and the lens 323 is fixedly connected to the connecting base 3242. The central axis of the fixed base 3223 is aligned with the horizontal observation direction of the eyepiece. The principal optical axis of the lens 323 is coaxial with the axis of rotation of the first rotating arm 2. The rotating base 3241 is configured to perform a second swing around the central axis of the fixed base 3223, thereby driving the lens 323 to perform a second swing. The third locking knob 322 is disposed on the fixed base 3223 and is configured to lock or unlock the rotating base 3241 by contacting or moving away from the second clamp 3222. The third rotating assembly 324 also includes a decorative cover 3244 and a pentaprism 3243. The pentaprism is located inside the rotating base, and the decorative cover covers the top of the rotating base.
[0034] It should be noted that in this invention, the first clamp 15, the second clamp 3222 and the third clamp 226 are based on the same principle and have the same or similar structure, and will not be described in detail here.
[0035] The fixing base 3223 of the third rotating component 324 of the present invention is connected to the eyepiece observation component 321 in the horizontal direction, which increases the horizontal operating space and distance. In a more reasonable ergonomic posture, the doctor can complete the operation without leaning forward. As shown in Figure 13, in the horizontal observation direction of the eyepiece, the horizontal distance between the central axis of the first cylindrical structure and the observation point of the eyepiece is 180mm-300mm. Preferably, the horizontal distance between the central axis of the first cylindrical structure and the observation point of the eyepiece is 260mm.
[0036] As shown in Figures 12(a) to 14(b), when a doctor needs to tilt the microscope left and right to observe the patient's molars, the third rotating component 324 can tilt the lens 323 without changing the doctor's eye position, achieving the tilt within a left-right swing angle of ±23°. The tilting posture of the lens 323 can be locked by the third locking knob 322. In another embodiment, there is no limitation on the left-right tilting angle of the lens 323.
[0037] As shown in Figure 16(a), with the doctor's current observation position as the initial position, the first swing is the back-and-forth swing of the scope 32, and the second swing is the left-and-right swing of the lens 323. Figure 2 As shown in Figure 16, the angle between the main optical axis 5 of the back-and-forth swinging lens body 32 and the axis 4 of the first rotating arm 2 is 0-90°, and the angle between the main optical axis 5 of the left-and-right swinging lens 323 and the axis 4 of the first rotating arm 2 is 0-23°.
[0038] Please see Figure 15 Along a direction perpendicular to the horizontal observation direction of the eyepiece, beam splitters are connected to opposite sides of the mounting base 3223, and electronic components are connected to the beam splitters. The mounting base 3223 of the third rotating assembly 324 of this invention has built-in beam splitting systems on both sides, which increases the possibility of using auxiliary equipment and allows doctors to choose from a wider range of microscope accessories. These electronic devices include, but are not limited to, cameras and mobile phones.
[0039] Please refer to Figures 16(a) and 16(b). The movement process of the surgical microscope of the present invention is as follows: When the doctor observes the patient's teeth in the initial position shown in Figure 16(a), when it is necessary to change the observation angle, the doctor holds the handle 35 and rotates the first rotating arm 2. At this time, the microscope body 32 only rotates horizontally, and the field of view of the lens 323 does not change. There is no need to readjust the focus of the microscope. After rotating to the correct position, the first rotating arm 2 is fixed by tightening the first locking knob 16, which greatly improves the work efficiency and adjustment flexibility, while ensuring the rotation accuracy. When the doctor needs to adjust the front and back observation angles, loosen the second locking knob 212, and pull or push the microscope handle 35 forward. The balance shaft 221 in the second rotating assembly 220 rotates, causing the second rotating arm 31 to rotate. The second rotating arm 31 then causes the microscope body 32 to swing back and forth. When the microscope body 32 is rotated to the appropriate angle, the second locking knob 212 is used to lock it in place. When the doctor needs to adjust the left and right observation angles, loosen the third locking knob 322, and swing the microscope handle 35 left and right. The rotating seat 3241 in the third rotating assembly 324 rotates, causing the connecting seat 3242 to rotate. This causes the lens 323 to swing left and right. When the microscope body 323 is rotated to the appropriate angle, the third locking knob 322 is used to lock it in place. At this time, the eyepiece observation assembly 321 remains stationary, and the doctor does not need to change the position of their eyes.
[0040] Referring to Figure 16(b), the lens center of gravity B in Figure 16(b) is not on the main optical axis. As the position of the center of gravity changes with the addition of external accessories to the lens, the lens body is adjusted back and forth by the second rotating assembly. In order to make the operation more comfortable and flexible for the user when the lens swings back and forth, the present invention places the rotation center A of the second rotating arm on the vertical line of the lens center of gravity B, and the rotation center A is as close as possible to the position of the center of gravity B. This can obtain a pendulum effect in a horizontal state, that is, in the natural state, the lens is in a horizontal state. The closer the distance H between the lens center of gravity B and the rotation center A of the second rotating arm, the smaller the gravitational torque when the lens swings back and forth, and the less force the operator needs to rotate and adjust the angle of the lens, making the adjustment easy and flexible.
[0041] The present invention has the following beneficial effects: 1. The surgical microscope provided by the present invention has high operational flexibility. By designing the main optical axis of the microscope to be coaxial with the axis of rotation of the first rotating component, when the doctor moves horizontally in a seated position, the doctor holds the handle so that the microscope body only needs to rotate around the axis. At this time, the axes of the main optical axis and the axis of rotation of the first rotating component remain coaxial. The doctor can see the treatment area clearly from multiple angles without readjusting the microscope.
[0042] 2. The surgical microscope provided by this invention combines three rotating structures, resulting in high flexibility: the microscope body swings back and forth with the rotation axis of the second rotating component, enabling diagnosis and treatment of the upper and lower positions of the oral cavity. At this time, only the position of the eyepiece needs to be adjusted up and down. Or, when the amplitude of the back and forth swing of the microscope body with the rotation axis of the second rotating component is small, the doctor only needs to make slight adjustments to his head. The doctor's eyes do not need to leave the eyepiece tube to observe, making the operation more flexible. At the same time, the doctor's sitting posture does not need to change. The microscope lens swings left and right with the rotation axis of the third rotating component, and the initial observation position of the eyepiece remains unchanged. The doctor's sitting posture does not need to change.
[0043] 3. The surgical microscope provided by this invention increases the horizontal operating space and distance, allowing doctors to complete operations without leaning forward in a more reasonable ergonomic posture.
[0044] 4. The surgical microscope provided by this invention uses a second rotating assembly to adjust the scope body back and forth. In order to make the operation more comfortable and flexible for the user when the lens swings back and forth, this invention places the rotation center A of the second rotating arm on the vertical line of the lens's center of gravity B, and the rotation center A is as close as possible to the center of gravity B. This achieves a pendulum effect in a horizontal state, meaning that the lens is horizontal in its natural state. The closer the distance H between the lens's center of gravity B and the rotation center A of the second rotating arm, the smaller the gravitational torque when the lens swings back and forth. The less force the operator needs to exert when rotating and adjusting the lens angle, the easier and more flexible the adjustment.
[0045] 5. The surgical microscope rotating device provided by the present invention has a first clamp fitted on the connecting shaft of the first rotating component. In the prior art, when the first locking knob locks the connecting shaft through the locking rod, the locking rod of the first locking knob directly abuts against the connecting shaft. This causes the locking rod of the first locking knob to directly contact the connecting shaft, resulting in a dent on the connecting shaft and thus a loose locking mechanism. Therefore, the present invention, by having the locking rod directly abut against the first clamp when the first locking knob locks the connecting shaft through the locking rod, makes the locking more secure and will not damage the connecting shaft, thereby improving the rotation accuracy and extending the life of the microscope.
[0046] 6. The surgical microscope rotation device provided by this invention adds a coil spring to the balance shaft to balance the torque generated by the lens. When the microscope body automatically falls back, the coil spring applies a counterforce to balance the falling force, causing the microscope body to fall slowly. This allows users to more easily rotate the lens without having to forcefully resist the torque generated by the lens's movement. It also reduces damage to parts and extends the service life by 5-10 years. When users add accessories that change the lens's center of gravity, the coil spring torque can be adjusted via a worm gear mechanism to rebalance the new lens weight.

In this embodiment, the surgical microscope differs from the previous embodiment in that the binocular observation component 421, the third rotation component, and the lens 423 rotate as a single unit. The microscope body 40 includes a second rotating arm 41 and a microscope body 42. The microscope body 42 includes an eyepiece observation component 421, a third rotation component 424, and a lens 423. The third rotation component 424 includes a rotating ring 4241, a pivot seat 4242, and a fixed seat 4243. Along the horizontal observation direction of the eyepiece, the eyepiece observation component 421, the fixed seat 4243, the rotating ring 4241, and the pivot seat 4242 are connected in sequence. One end of the second rotating arm 41 is rotatably connected to the first rotating arm 2, and the other end is fixed to the pivot seat 4242. The lens 423 is fixedly connected to the lower side of the rotating ring 4241, and the principal optical axis of the lens 423 is coaxial with the axis of rotation of the first rotating arm 2. In another embodiment, the main optical axis of the lens 423 is substantially coaxial with the axis of rotation of the first rotating arm 2.
[0048] Along the horizontal observation direction of the eyepiece, the central axis of the rotating ring 4241 and the central axis of the rotating shaft seat 4242 are coaxial. The rotating ring is configured to perform a third oscillation around the central axis of the rotating shaft seat, which drives the lens, the mounting base, and the eyepiece observation assembly to perform this third oscillation. Along a direction perpendicular to the horizontal observation direction of the eyepiece, beam splitters are connected to opposite sides of the mounting base. These beam splitters can be connected to electronic products, etc.
