In addition, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0029] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the terms "mount", "connect", "connection" should be understood in broad sense, for example, it can be fixed connection, also can be detachable connection, or integrally connected, it can be direct connection, also can be indirect connection through intermediate medium, it can be the communication inside two elements, the above-mentioned terms in the utility model can be understood according to specific circumstances by the ordinary skill in the art.

[0030] 3D image technology has wide application in the medical field, for example, 3D high-definition laparoscope technology is a very important surgical auxiliary means, which provides three-dimensional surgical field of view, so that the doctor can more accurately judge the anatomical structure, thereby improving the accuracy and safety of the operation, and in the operation process, the doctor needs to switch repeatedly between 3D visual mode and ordinary visual mode, and the process of the doctor switching the visual field cannot be finely operated by hand, and needs to frequently ask for help from the assistant, and it also needs a long time for the doctor to ask for help from the assistant to the assistant to complete the lens changing process, which leads to the incoherent operation of the doctor, not only affects the operation efficiency, but also increases the operation risk.

[0031] In the prior art, there is a pair of glasses capable of switching visual mode, but the glasses in the prior art need the user to lift the outer lens with hands when switching the visual mode, and the hand needs to complete complex and precise operation in the process, for the operation process with high sterility requirement, the doctor cannot touch the glasses with hands, therefore, the doctor cannot switch the visual mode by himself.

[0032] Therefore, the utility model embodiment designs a kind of surgical 3D glasses 100 capable of quickly switching visual mode, which can conveniently switch visual mode to 3D mode, and also can one-key switch visual mode back to ordinary mode, the switching process between two visual modes is rapid, switching operation is convenient and simple, and the doctor can complete it by himself, which can greatly improve the operation fluency while meeting the sterility requirement, improve the operation efficiency, and reduce the operation risk.

[0033] The surgical 3D glasses 100 capable of quickly switching visual mode according to the utility model embodiment are described below with reference to the accompanying drawings.

[0034] As shown in Figures 1-2 According to the utility model embodiment, the surgical 3D glasses 100 capable of quickly switching visual mode include a frame assembly 1 and a switching lens frame 2.

[0035] The frame assembly 1 includes lens legs 11 and a main lens frame 12 connected to each other, and the surgical 3D glasses can be hung stably above the doctor's ear by means of the lens legs 11, so that the main lens frame 12 can be stably and accurately placed in front of the doctor's eyes.

[0036] The main mirror frame 12 is provided with a first lens mounting position 121, which can be mounted with myopic lenses, piano lenses or hyperopic lenses, etc. Doctors can personalize the lenses according to their own needs to ensure a clear field of view in the ordinary vision mode. This design is especially convenient for doctors who already wear glasses. At the same time, the lenses installed in the first lens mounting position 121 can also play a protective role, effectively preventing the patient's body fluids from splashing into the doctor's eyes. Of course, the first lens mounting position 121 can also be selected not to install lenses to enhance the universality of the glasses.

[0037] In some embodiments, the lenses installed at the first lens mounting position 121 can be conveniently removed, and different doctors can install lenses suitable for themselves before the operation, so that a pair of surgical 3D glasses can be used by different doctors.

[0038] The switching mirror frame 2 is provided with a second lens mounting position 21 for mounting a second lens, which is usually a 3D lens.

[0039] The switching mirror frame 2 can rotate between a first position and a second position. When the switching mirror frame 2 is in the first position, it covers the front surface of the main mirror frame 12. At this time, if the second lens is a 3D lens, the doctor wearing the surgical 3D glasses 100 can obtain clear 3D visual effect, that is, the surgical 3D glasses 100 enter the 3D vision mode.

[0040] When the switching mirror frame 2 is rotated to the second position, the switching mirror frame 2 is in an upwardly turned state, and the position of the switching mirror frame 2 does not affect the doctor's normal vision and reserves enough angle for the subsequent doctor to rotate the switching mirror frame 2 back to the first position. At this time, the surgical 3D glasses 100 are in the ordinary vision mode.

[0041] During the operation, the doctor often needs to frequently switch between the two vision modes according to the operation process. However, if the doctor purely relies on manual driving to rotate the switching mirror frame 2 from the first position to the second position, the operation process will be very complicated. Because the switching mirror frame 2 and the 3D lens thereon are parallel to the doctor's face and the lens on the main mirror frame 12, the doctor needs to apply force to the side of the switching mirror frame 2 facing away from the face from the side facing the face. This requires the doctor to either apply force to the switching mirror frame 2 at the edge thereof by means of friction or to stretch the fingers between the switching mirror frame 2 and the main mirror frame 12 to apply force outwardly. In this process, the doctor also needs to hold the main mirror frame 12 to prevent it from following the switching mirror frame 2 to turn upward and causing the glasses to fall off the face. Such a complicated and delicate operation is difficult to complete without the aid of hands.

[0042] To solve this problem, the application embodiment ingeniously designs a torsion spring 4 between the switching mirror frame 2 and the main mirror frame 12. The torsion spring 4 can provide the required force for the switching mirror frame 2 to rotate from the first position to the second position. The doctor only needs to easily release the locking between the switching mirror frame 2 and the frame assembly 1, and the switching mirror frame 2 will automatically rotate to the second position. The separation process of the switching mirror frame 2 and the main mirror frame 12 does not need to be fine, which provides convenience for the doctor to use the shoulder, elbow and other parts to switch the visual mode.

[0043] Specifically, the switching mirror frame 2 is hinged to the upper edge of the main mirror frame 12 through a rotating shaft. In this way, when the switching mirror frame 2 is separated from the main mirror frame 12, it can be flipped up to the front side of the doctor's forehead, which does not affect the normal operation of the doctor and does not interfere with the face.

[0044] The rotating shaft is provided with an axially extending torsion spring 4, the first end of which is fixed on the main mirror frame 12, and the second end is fixed on the switching mirror frame 2, so that the switching mirror frame 2 has a tendency to automatically rebound to the second position between the first position covering the front surface of the main mirror frame 12 and the second position of flipping up. Therefore, the torsion spring 4 can provide a restoring force for the switching mirror frame 2, so that it automatically rotates to the second position without external force, realizing the separation of the main mirror frame 12 and the switching mirror frame 2.

[0045] Therefore, without the doctor applying force by himself, the switching mirror frame 2 can move to the second position by itself, simplifying the operation of the doctor and improving the visual switching efficiency.

[0046] Among them, the frame assembly 1 is provided with a locking piece 5, and the switching mirror frame 2 is provided with a matching piece 7. When the switching mirror frame 2 rotates to the first position, the matching piece 7 will be locked by the locking piece 5, so that the switching mirror frame 2 can overcome the elastic force exerted by the torsion spring 4, and be fixed in the first position, so that the surgical 3D glasses remain in the 3D visual mode. When the doctor needs to switch from the normal visual mode to the 3D visual mode, he only needs to push the switching mirror frame 2 towards the face with his arm or with the help of external objects. After being pushed to the first position, the switching mirror frame 2 will be automatically locked by the locking piece 5, which is simple and convenient for the doctor to complete by himself.

[0047] The locking piece 5 is provided with an unlocking button 6, and pressing the unlocking button 6 can unlock the locking piece 5. At the same time when the locking piece 5 is unlocked, the switching mirror frame 2 will rotate to the second position under the elastic force exerted by the torsion spring 4. The doctor only needs to press the unlocking button 6 once, and the surgical 3D glasses can be switched to the normal visual mode. The operation of pressing the unlocking button 6 does not need to use hands, but only needs to use the shoulder, elbow or even touch the unlocking with the help of external objects, which greatly simplifies the operation and enables the doctor to complete the mode switching independently.

[0048] The operation of mode switching of the surgical 3D glasses 100 with the visual mode capable of being quickly switched is simple, fine operation is not required, a doctor can complete mode switching by using a shoulder, an elbow and the like, assistance is not required, surgical efficiency is effectively improved, and surgical risk is reduced.

[0049] The first lens and the second lens both need to adopt a material with high light transmission, scratch resistance, lightness and wear resistance to ensure visual effect.

[0050] The cooperation relationship between the locking part 5 and the cooperation part 7 needs to meet two conditions, the first condition is that the locking part 5 should release the locking of the cooperation part 7 after the unlocking button 6 is pressed, and the second condition is that the locking part 5 should automatically cooperate with the cooperation part 7 to fix the cooperation part 7 and the switching lens frame 2 connected with the cooperation part 7 when the switching lens frame 2 is rotated to the first position.

[0051] In some embodiments, the locking part 5 cooperates with the cooperation part 7 through a mechanical structure thereon to realize the fixing of the cooperation part 7 and the switching lens frame 2 connected with the cooperation part 7.

[0052] Specifically, referring to Figure 2 and Figure 3 , the locking part 5 adopts an elastic buckle mechanism 51, which includes a clamping groove 511 and a movable clamping tongue 512. The clamping tongue 512 is linked with the unlocking button 6 through a connecting rod 513 mechanism, when the unlocking button is pressed, the connecting rod 513 drives the clamping tongue 512 to exit the clamping groove 511, the cooperation part 7 loses the limiting of the clamping tongue 512, the locking is released, and the unlocking and separation of the locking part 5 to the cooperation part 7 are realized.

[0053] The locking part 5 further includes a reset spring, which can provide a reset force for the clamping tongue 512 to return to the clamping groove 511, after the locking part 5 is unlocked, the doctor removes the pressure on the unlocking button 6, and the clamping tongue 512 returns to the clamping groove 511 under the action of the reset force provided by the reset spring, so as to lock the cooperation part 7 again.

[0054] Specifically, the cooperation part 7 has a guide part, and the clamping tongue 512 is provided with a cooperation guide part, during the movement of the switching lens frame 2 to the first position, the guide part on the cooperation part 7 first contacts the cooperation guide part provided on the clamping tongue 512, during the movement of the switching lens frame 2 to the first position, the cooperation part 7 applies pressure to the clamping tongue 512 through the contact of the guide part and the cooperation guide part, drives the clamping tongue 512 to move out of the clamping groove 511, until the switching lens frame 2 moves to the first position, the cooperation part 7 completely enters the clamping groove 511, the cooperation between the cooperation guide part on the clamping tongue 512 and the guide part of the cooperation part 7 is no longer contacted, and the clamping tongue 512 returns to the clamping groove 511 under the action of the reset force of the reset spring to lock and limit the cooperation part 7.

[0055] The locking piece 5 adopts an elastic buckle mechanism 51, is convenient to assemble, and ensures the reliability of the locking piece 5.

[0056] In other embodiments, referring to Figure 1 , the locking piece 5 adopts an electromagnet 52, and the cooperating piece 7 adopts an iron sheet; in a normal state, the electromagnet 52 is powered to generate a magnetic attraction force to fixedly connect the iron sheet to the electromagnet 52; the unlocking button 6 is pressed to disconnect the circuit between the electromagnet 52 and the power supply, the magnetic force disappears, and automatic separation is realized. The locking piece 5 adopts the electromagnet 52, the corresponding speed is faster, and intelligent control can be realized.

[0057] According to an embodiment of the utility model, the surgical 3D glasses 100 further include a remote controller and a wireless control module; the wireless control module is integrated in the locking piece 5 and is used for receiving signals from the remote controller and controlling the locking piece 5 to be unlocked. Therefore, the doctor can press the unlocking button 6 on the remote controller in any way to control the remote controller to send signals to control the locking piece 5 to be unlocked, for example, stepping on the foot pedal, and the like, which is more convenient for the doctor to operate.

[0058] The remote controller can adopt a waterproof and anti-skid design, is equipped with a multi-band transmitting module, supports multi-band communication, and ensures signal stability in a complex electromagnetic environment of an operating room. The wireless control module is integrated inside the locking piece 5 of the frame assembly 1, contains a signal receiver, a microprocessor and a driving circuit, and the like, and can further add a vibration module in the remote controller to transmit an operation confirmation signal to the doctor, so that repeated triggering is avoided

[0059] For example, when the locking piece 5 is the electromagnet 52, the wireless control module can directly control a power supply circuit of the electromagnet 52, and immediately disconnects the circuit after receiving the signal.

[0060] For example, when the locking piece 5 is the elastic buckle mechanism 51, a micro linear motor can be added in the locking piece 5 as an execution mechanism, and the micro linear motor is controlled to operate by the wireless control module.

[0061] The remote controller can adopt multi-modal control, for example, the remote controller can be a foot pedal trigger, the doctor can send an unlocking signal by stepping on the foot pedal, and the remote controller can also be a voice receiver with a keyword recognition function, and sends an unlocking signal after receiving an unlocking instruction. The remote controller is used for remote control unlocking, which can be more convenient for the leading doctor to independently operate the surgical 3D glasses, and reduces the dependence on an assistant.

[0062] The remote controller can also be held in the hand of the assistant, and the doctor does not need to arrange the assistant to come to the side of the doctor to perform lens replacement operation; the assistant can operate the lens state of the doctor at the original position of the assistant, and the demand of the doctor is responded more timely.

[0063] According to an embodiment of the utility model, referring to Figure 1 andFigure 2 The locking part 5 is arranged on the side of the temple 11 away from the main frame 12, so that the spatial layout of the surgical 3D glasses is more reasonable. The locking part 5 is arranged on the outer side of the temple 11 away from the main frame 12, effectively avoiding spatial interference with the facial contours of the doctor, such as the cheekbone and the temple. This layout keeps the inner side of the temple 11, that is, the side close to the face, smooth and curved, in line with the human facial engineering curve, and improves the wearing comfort. The matching part 7 is arranged at the end of the switching frame 2 close to the temple 11, and is clamped with the locking part 5 on the outer side of the temple 11, reducing the complexity of the matching process

[0064] Arranging the locking part 5 on the side of the temple 11 away from the main frame 12 also facilitates the operation of the doctor. The unlocking button 6 can be exposed on the outer side surface of the temple 11, so that the doctor can trigger it by lightly touching the side of the surgical 3D glasses 100 through the shoulder, elbow or a sterile rod or the like,

[0065] In some embodiments, the unlocking button trigger stroke should be more than 3mm to avoid accidental triggering. An outer silicone protective cover should be arranged on the unlocking button 6 to prevent liquid splashing from invading during surgery.

[0066] According to an embodiment of the present application, the pressing direction of the unlocking button 6 when pressed points to the head and face of the doctor. Therefore, when driving the unlocking button 6 to switch modes, the doctor only needs to apply force to the unlocking button 6, and the position of the surgical 3D glasses can be limited by the head and face of the doctor, and will not move away from the face of the doctor due to force.

[0067] In some embodiments, the doctor can place the head on the shoulder, so that the unlocking button 6 is located between the head and the shoulder, and the pressing drive of the unlocking button 6 can be achieved after the head and the shoulder are clamped. The pressing process will not affect the wearing effect of the surgical 3D glasses of the medical staff.

[0068] According to an embodiment of the present application, in the second position, the flip angle of the switching frame 2 is not less than 110 degrees and not more than 160 degrees. The flip angle of the switching frame 2 not less than 110 degrees can ensure that the switching frame 2 is completely separated from the plane of the main frame 12, avoiding cutting interference of the residual lens edge on the line of sight. The flip angle of the switching frame 2 not more than 160 degrees can prevent the switching frame from touching the overhead equipment of the doctor due to excessive flipping, and provide enough space for the doctor to drive the switching frame 2 back to the first position, while maintaining the center of gravity of the frame within the support range of the pivot

[0069] According to an embodiment of the present application, the main frame 12 is provided with a limiting protrusion, and in the second position, the surface on the side of the switching frame 2 away from the main frame 12 cooperates with the limiting protrusion.

[0070] The main mirror frame 12, the limiting protrusion and the switching mirror frame 2 can jointly form a triangular support structure, stably support the switching mirror frame 2 in the second position, and accurately limit the overturning angle of the switching mirror frame 2 at a preset angle, so as to ensure that the switching mirror frame 2 completely avoids the visual field area after being overturned and reserve sufficient space for subsequent return operation.

[0071] In some embodiments, the contact surface of the limiting protrusion and the switching mirror frame 2 can be designed with a protection structure, so that the switching mirror frame 2 can be in soft contact with the limiting protrusion after being turned to the second position, the damage caused by high-speed collision of the limiting protrusion and the switching mirror frame 2 is reduced, the friction loss of the contact surface is reduced, and the mechanical noise during operation is reduced.

[0072] According to an embodiment of the present application, the frame assembly 1 adopts a medical-grade titanium alloy frame, the titanium alloy material has low density and light weight, and wearing is more comfortable, the material surface is treated and can withstand high temperature and high pressure sterilization, meets the disinfection requirement, the titanium alloy material also has good corrosion resistance, avoids corrosion under long-time sweat contact, and also has non-magnetic properties, and can adapt to different surgical environments.

[0073] According to an embodiment of the present application, the first lens mounting position 121 is selectively mounted with a plane lens or a corrective lens, and the second lens mounting position 21 is mounted with a 3D lens, so that switching between the 3D mode and the ordinary myopia mirror mode can be realized.
