Description

Technical Field

[0001] The utility model relates to the field of precision instruments, in particular to a surgical microscope lens stabilizing mechanism and a surgical microscope. Background Art

[0002] A microscope is a precision instrument with a wide range of applications in biology. Microscopes are generally divided into optical microscopes and electron microscopes. Optical microscopes are commonly seen in the dental industry. One of the most important performance characteristics of a microscope is its imaging effect. In daily use by doctors, it is inevitable that the surgical microscope will be moved or bumped, causing the screen to shake, affecting the screen display and the doctor's observation efficiency.

[0003] The inventors have found that the surgical microscopes in the prior art have at least the following disadvantages:

[0004] 1. When the doctor moves the surgical microscope or accidentally bumps into it, the image of the microscope will shake significantly, and it takes a long time for the microscope to stabilize from the shaking, which is not conducive to observation;

[0005] 2. Due to the different selection of lens modules, the overall weight of the lens part is also inconsistent. When using different lens modules, it is difficult to ensure the balance of the lens assembly and the stability of the field of view. Doctors need to adjust it manually, which is time-consuming and labor-intensive, and reduces the doctor's operating efficiency. Utility Model Content

[0006] The utility model aims to provide a surgical microscope lens stabilization mechanism and a surgical microscope, which can shorten the shaking time of the lens assembly, and the lens assembly can quickly stabilize and be easy to use; at the same time, it can adapt to the selection of different lens modules, shorten the time required for adjusting the lens assembly, and improve surgical efficiency.

[0007] The embodiment of the utility model is achieved as follows:

[0008] In a first aspect, the utility model provides a surgical microscope lens stabilization mechanism, comprising:

[0009] A balance arm assembly and a lens assembly, wherein the balance arm assembly is provided with at least one rotating joint, wherein the rotating joint comprises a first connecting arm, a second connecting arm and a gyro motor, wherein the first connecting arm and the second connecting arm are rotatably matched, the housing of the gyro motor is mounted on the first connecting arm, and the rotating shaft of the gyro motor is mounted on the second connecting arm; and the lens assembly is connected to the first connecting arm or the second connecting arm.

[0011] Based on the above scheme, by setting up an installation chamber, the gyro motor is embedded in the installation chamber. The gyro motor and the first connecting arm are compactly combined and small in size, which is conducive to the miniaturization and lightweight design of the surgical microscope. Since the overall structure is small in size and occupies little space, the probability of collision during use is small, and the operation is more convenient.

[0012] In an optional embodiment, at least a portion of the hole segment of the assembly hole is set as a non-circular hole segment, the cross-sectional outer contour of at least a portion of the shaft segment of the rotating shaft is set as a non-circular hole segment, and the shaft segment with a non-circular cross-sectional contour of the rotating shaft is plugged into the non-circular hole segment of the assembly hole.

[0013] Based on the above scheme, after the rotating shaft of the gyro motor is inserted into the assembly hole, the rotating shaft of the gyro motor and the assembly hole realize circumferential limitation, and the rotating shaft of the gyro motor can drive the second connecting arm to rotate, thereby automatically adjusting the angle of the first connecting arm and the second connecting arm, which is flexible to use.

[0014] In an optional embodiment, there are multiple rotational joints, and the rotation axes of at least two of the multiple rotational joints have an included angle.

[0015] Based on the above solution, by providing a plurality of rotating joints, and the rotating axes of at least two rotating joints have an angle, when the lens assembly moves, the adjustable range is wider, and the use is more flexible and convenient.

[0016] In an optional embodiment, the surgical microscope lens stabilization mechanism further includes a control panel, wherein the control panel is mounted on the lens assembly, the control panel is communicatively connected to the gyro motor, and the control panel is used to adjust the working state of the gyro motor.

[0017] Based on the above scheme, by setting up a control panel, when it is necessary to adjust the working state of the gyro motor, for example, by driving the corresponding rotating joint to rotate through the gyro motor to adjust the angle, or when it is necessary to lock the gyro motor, the control panel can be directly operated, which is convenient to operate.

[0018] It should be understood that the position of the control panel can be set as needed, as long as it can be operated by the operator. The control panel can be set as a key panel or a touch panel.

[0019] In an optional embodiment, the surgical microscope lens stabilization mechanism further includes a handle, and the handle is mounted on the lens assembly.

[0020] Based on the above solution, when adjusting the position of the lens assembly, the handle is held, which is not easy to slip, and the operation is time-saving and labor-saving.

[0026] Based on the above solution, the position of the lens assembly can be adjusted by adjusting the positions of the column, the first cross arm and the second cross arm, and the lens assembly can be used more flexibly.

[0027] In an optional embodiment, a brakeable walking wheel set is provided on the base.

[0028] Based on the above solution, the walking wheel group is convenient to move on the ground, and after moving to the set position, the walking wheel group is locked, and the walking wheel group achieves stable support. When operating the lens assembly, the base is not easy to move, and the operation is convenient.

[0029] The beneficial effects of the embodiments of the utility model are:

[0030] In summary, the surgical microscope lens stabilization mechanism provided in this embodiment, by setting a balance arm assembly, when the lens assembly shakes due to misoperation or collision during use, the balance arm assembly can stabilize the lens assembly, so that the lens assembly quickly stabilizes from a shaking state, thereby improving the operating efficiency. Specifically, when the lens assembly shakes, the torque generated by the shaking is transmitted to the gyroscope motor. The gyroscope is an instrument for measuring the angular velocity of rotation, which includes a rotor and a sensing device. When the rotor rotates, the sensing device generates a signal, and the rotation of the object can be judged by this signal. After the lens assembly is installed, the gyro motor installed between the first connecting arm and the second connecting arm will detect the relative rotation of the first connecting arm and the second connecting arm and convert it into an electrical signal to feed back to the circuit board that controls the gyro motor. Therefore, during the movement or shaking of the lens assembly, the first connecting arm and the second connecting arm will rotate, and the torque generated by the rotation is transmitted to the gyro motor. The rotor rotates relative to the sensing device, and the sensing device generates an electrical signal after sensing the rotation of the rotor. The circuit board can process the received electrical signal to make the gyro motor move in the opposite direction for compensation, thereby achieving rapid stabilization of the lens assembly. In this way, when the doctor moves the surgical microscope or accidentally bumps into it, the imaging picture of the microscope can stabilize more quickly, thereby improving operating efficiency.

[0031] At the same time, when different lens modules are selected, the angle of the lens assembly is positioned by the gyro motor. The gyro motor can realize automatic adjustment of the angle of the lens assembly, which can always ensure the balance of the lens assembly and the stability of the field of view. There is no need to manually adjust the damping and balance, thereby improving the doctor's operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In the prior art, the lens assembly 200 achieves angle adjustment through multiple mechanical joints. During the use of the surgical microscope, when the lens assembly 200 is disturbed by external factors and causes the mechanical joints to rotate, the image obtained by the lens assembly 200 shakes, and it needs to rely on its own structure to achieve stability, which takes a long time and results in low operating efficiency.

[0045] In view of this, the designer provides a surgical microscope lens stabilization mechanism, which can shorten the time required for the lens assembly 200 to stabilize from shaking, improve operating efficiency, and at the same time, when replacing lens modules of different weights, the angle can be quickly adjusted.

[0046] Please combine Figure 1 and Figure 2 In this embodiment, the surgical microscope lens stabilization mechanism includes a balance arm assembly 100 and a lens assembly 200. The balance arm assembly 100 is provided with at least one rotating joint 110. The rotating joint 110 includes a first connecting arm 111, a second connecting arm 112 and a gyro motor 113. The first connecting arm 111 and the second connecting arm 112 are rotatably matched. The housing of the gyro motor 113 is installed on the first connecting arm 111, and the rotating shaft of the gyro motor 113 is installed on the second connecting arm 112; the lens assembly 200 is connected to the first connecting arm 111 or the second connecting arm 112.

[0047] Based on the above, the working principles of the balance arm assembly 100 and the lens assembly 200 provided in this embodiment are as follows:

[0048] A gyroscope is an instrument for measuring the angular velocity of rotation, which includes a rotor and a sensing device. When the rotor rotates, the sensing device generates a signal, and the rotation of the object can be determined by the signal. The rotor of the gyroscope is integrated with the rotating shaft of the motor, and the sensing device is installed on the housing of the motor, forming a gyroscope motor 113. When the lens assembly 200 shakes, the torque generated by the shaking is transmitted to the gyro motor 113. After the lens assembly 200 is installed, the gyro motor 113 installed between the first connecting arm 111 and the second connecting arm 112 will detect the relative rotation of the first connecting arm 111 and the second connecting arm 112 and convert it into an electrical signal to feed back to the circuit board 130 that controls the gyro motor 113. Therefore, during the movement or shaking of the lens assembly 200, the first connecting arm 111 and the second connecting arm 112 will rotate, and the torque generated by the rotation is transmitted to the gyro motor 113. The rotor rotates relative to the sensing device, and the sensing device generates an electrical signal after sensing the rotation of the rotor. The circuit board 130 can process the received electrical signal to make the gyro motor 113 move in the opposite direction for compensation, thereby achieving rapid stabilization of the lens assembly 200. In this way, when the doctor moves the surgical microscope or accidentally hits it, the imaging picture of the microscope can be stabilized more quickly, thereby improving operating efficiency.

[0049] At the same time, when different lens modules are selected, the angle of the lens assembly 200 is positioned by the gyro motor 113. The gyro motor 113 can realize automatic adjustment of the angle of the lens assembly 200, and can always ensure the balance and field of view of the lens assembly 200. There is no need to manually adjust the damping and balance, thereby improving the doctor's operating efficiency.

[0050] It should be understood that the gyro motor 113 is an existing well-known electronic product. In order to avoid repeated description, the detailed structure and working principle of the gyro motor 113 are not elaborated in detail in this application.

[0051] The following embodiments illustrate the details of the surgical microscope lens stabilization mechanism provided in the present application by way of examples.

[0052] Please combine Figure 1 In this embodiment, optionally, the surgical microscope lens stabilization mechanism includes a balance arm assembly 100, a lens assembly 200, a control panel 300 and a handle 400. The lens assembly 200 is connected to the support mechanism 500 of the surgical microscope through the balance arm assembly 100, the control panel 300 is connected to the balance arm assembly 100 for communication and can adjust the motion state of the balance arm assembly 100, and the handle 400 is installed on the lens assembly 200. The control panel 300 can be installed on the handle 400, or installed at other locations.

[0053] Please combine Figure 2Optionally, the lens assembly 200 balance arm assembly 100 includes two rotating joints 110 and a C-arm 120 connecting the two rotating joints 110. Specifically, the first connecting arm 111 of the first rotating joint 110 is connected to one end of the C-arm 120, and the two can be set as an integrated structure, and the first connecting arm 111 of the second rotating joint 110 is connected to the other end of the C-arm 120, and the two can be set as an integrated structure. The rotation axis of the first rotating joint 110 and the rotation axis of the second rotating joint 110 are perpendicular to each other. The second connecting arm 112 of the first rotating joint 110 is used to connect to the support mechanism 500 of the surgical microscope, and the second connecting arm 112 of the second rotating joint 110 is connected to the lens assembly 200.

[0054] It should be noted that the structure of each rotary joint 110 is set to be the same. In this embodiment, the structure of one rotary joint 110 is used as an example for description. Among them, the end of the first connecting arm 111 is provided with an installation chamber, and the installation chamber is provided with a circuit board 130. The housing of the gyro motor 113 is installed in the installation chamber and is electrically connected to the circuit board 130. The circuit board 130 is electrically connected to the control panel 300. The end of the second connecting arm 112 is provided with an assembly hole, which is a blind hole. At least part of the hole section of the assembly hole is set to a non-circular hole section, that is, the cross-sectional profile of at least part of the hole section of the assembly hole is non-circular. Correspondingly, the cross-sectional profile of at least part of the shaft section of the gyro motor 113 is set to be non-circular, so that after the first connecting arm 111 and the second connecting arm 112 are rotatably matched, the shaft of the gyro motor 113 is inserted into the assembly hole, and the shaft section with a non-circular cross-sectional profile of the shaft is plugged into the non-circular hole section of the assembly hole, and the shaft and the assembly hole are relatively fixed in the circumferential direction of the assembly hole, that is, the shaft will not rotate relative to the assembly hole. It should be understood that after the housing of the gyro motor 113 is plugged into the installation chamber, the housing of the gyro motor 113 and the first connecting arm 111 will not rotate relative to each other. In this way, by adjusting the gyro motor 113, the relative rotation of the first connecting arm 111 and the second connecting arm 112 can be controlled, and the angle of the first connecting arm 111 and the second connecting arm 112 can be adjusted.

[0055] Since the gyro motor 113 is electrically connected to the circuit board 130, and the circuit board 130 is electrically connected to the control panel 300, the operation state of the gyro motor 113 can be operated by manipulating the control panel 300, and the operation is convenient. For example, the gyro motor 113 can be driven by manipulating the control panel 300 to rotate the first connecting arm 111 relative to the second connecting arm 112, or when the surgical microscope stops working, the gyro motor 113 can be locked through the control panel 300, thereby locking the first connecting arm 111 and the second connecting arm 112, and the operation is convenient and quick.

[0056] In this embodiment, it should be noted that the number of the rotating joints 110 is not limited to two, and the number of the rotating joints 110 can be multiple and can be set as needed. In addition, when the number of rotating pipes is multiple, the rotation axes of at least two rotating joints 110 have a non-zero angle, the adjustment range is wide, and the lens assembly 200 is flexible to use.

[0057] When adjusting the state of the rotating joint 110 , it is achieved through the control panel 300 . The control panel 300 may be a touch type or a button type, etc., which is not limited in this embodiment.

[0058] The surgical microscope lens stabilization mechanism provided in this embodiment, by providing a rotating joint 110 with a gyro motor 113, can drive the lens assembly 200 to move in the opposite direction through the gyro motor 113 to compensate when the lens assembly 200 shakes, thereby achieving rapid stabilization of the lens assembly 200 and improving operating efficiency.

[0059] Please combine Figure 3 This embodiment also provides a surgical microscope, including a support mechanism 500 and a surgical microscope lens stabilization mechanism. The balance arm assembly 100 is connected to the support mechanism 500 to achieve rotatable cooperation between the lens assembly 200 and the support mechanism 500 through a rotating joint 110.

[0060] Optionally, the support mechanism 500 includes a base 510, a column 520, a first cross arm 530 and a second cross arm 540. The column 520 is rotatably mounted on the base 510, the first cross arm 530 is rotatably matched with the column 520, the second cross arm 540 is rotatably matched with the first cross arm 530, and the balance arm assembly 100 is rotatably matched with the second cross arm 540. A brakeable walking wheel set 550 is provided on the base 510.

[0061] Before using the lens assembly 200 , the relative positions of the column 520 , the first cross arm 530 , and the second cross arm 540 may be adjusted first, so as to facilitate adjustment of the position of the lens assembly 200 and facilitate subsequent use of the lens assembly 200 .

[0062] The surgical microscope provided in this embodiment has at least the following advantages:

[0063] 1. After the surgical microscope is moved or accidentally bumped, the microscope's image can be stabilized more quickly.

[0064] 2. When lens modules of different weights are selected, the balance and field of view of the lens assembly 200 can be always guaranteed, without the need to manually adjust the damping and balance, thereby improving the doctor's operating efficiency.

[0065] 3. The control panel 300 provided on the handle 400 enables the doctor to adjust the lens angle and lock it with one key more conveniently, without the need to tighten the knob, thus reducing the operation time.

[0066] 4. Lock the motor with one button when not in use, so it will not continue to work during idle time, which will increase the motor life and anti-shake effect.

[0067] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
