Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a microscope imaging device used in ophthalmic surgery. Background Art

[0002] Imaging is the imaging technology of biological samples. According to the size of the sample, it can be roughly divided into tissue imaging and cell molecular microscopy. These generally require optical technology to be developed in conjunction with the characteristics of biological samples. A few will use wave properties other than light, such as nuclear magnetic resonance, ultrasound, etc.

[0003] At present, when ophthalmologists are undergoing ophthalmic surgery, they generally use electron microscopes to observe the patient's eyes to assist doctors in observing the patient's eyes during surgery. However, there are still some inconveniences when using conventional electron microscopes to observe the patient's glasses: 1. At present, when using electron microscopes to operate on patients, there is often no device to mark the eyes, so when doctors operate on patients, they often need to observe the lesion area of ​​the patient's eyes at all times. During the long operation, it is easy to cause fatigue to the doctor, resulting in safety hazards during the operation; 2. When performing surgery on a patient, the electron microscope currently used is not equipped with a device to hold the patient's eyelids open, which causes certain inconveniences when performing surgery on the patient.

[0016] In the present invention, the patient who needs to undergo surgery is first transferred to the operating table, and the electron microscope is moved to the area where the patient's eye is to be operated on by adjusting the vertical electric guide rail, the horizontal electric guide rail and the arc-shaped electric guide rail respectively. Then, the position of the electron microscope is finely adjusted by rotating the support plate so that the electron microscope can accurately correspond to the patient's eye. Then, the handle can be pushed to drive the fixing bolt to rotate. At this time, under the threaded transmission action of the threaded support rod, the second rubber ring can be driven to approach the first rubber ring until the second rubber ring is tightly fitted with the first rubber ring, so that the threaded support rod can be adjusted. The support rod is stably braked, so that the angle set by the electron microscope can be limited. After the two eyelid stretching plates are sterilized in advance, the insertion rod can be inserted into the clamping ring. Then, the positioning screw can be twisted to insert one end of the positioning screw into the positioning groove to connect with the insertion rod, and the first connecting frame is laterally slidably connected to the supporting ring through the first slide plate. The positions of the two eyelid stretching plates can be adjusted by moving the first connecting frame according to actual needs, and after the adjustment is completed, the first clamping rod can be released, and the first tension spring in a stressed state can drive the first clamping rod to be inserted downward The gooseneck tube is inserted into the corresponding card slot, so that the first connecting frame can be limited, and the gooseneck tube itself has plasticity, so it can be easily bent, so that the positions of the two eyelid stretching plates can be adjusted, so that the two eyelid stretching plates can be aligned with the patient's eyes, and then the two threaded plates are driven away from each other by rotating the bidirectional screw, so that the two eyelid stretching plates can be driven away from each other, so that the patient's eyelids can be stretched open, so that the doctor can perform surgery on the patient's eyes. At the same time, the position of the laser pen can be adjusted by moving the second connecting frame horizontally, and at this time, it can be adjusted according to the patient's eye. The position of the laser pen is adjusted by the position, and after the position adjustment of the laser pen is completed, the second clamping rod can be released, and the second tension spring in a stressed state can pull the second clamping rod downward to make the second clamping rod and the corresponding clamping slot be clamped, and then the pull plate is pulled longitudinally to drive the adjustment rack to move longitudinally. At this time, under the meshing transmission action with the gear rack, the gear rack can be driven to rotate. When the gear rack rotates, the angle of the laser pen can be adjusted, so that the light emitted by the laser pen can be aimed at the affected part in the patient's eye, so that the surgical position can be marked. Please refer to the attached Figure 1, because multiple laser ray pens are designed, the laser ray pens can not only irradiate the patient's site, but also irradiate the incision entry position of the eyeball surgery, specifically: plan the surgical incision entry position of the eyeball in advance, and then use the corresponding laser ray pen to irradiate the corresponding surgical incision position. During the operation, the doctor can perform high-precision surgery according to the irradiated laser position, thereby improving the success rate of the operation. After the angle position of the laser ray pen is adjusted, the gear frame can be braked under the cooperation of the static friction force between the outer friction ring and the inner friction ring, thereby braking the laser ray pen. In the technical solution, the position of the electron microscope is adjusted by moving the adjustment plate horizontally, which can drive the connecting plate and the connecting cover to rotate, and can slide between the connecting plate and the connecting cover. After the position of the adjustment plate is adjusted, the first magnet and the second magnet can be attracted to each other, thereby limiting the connection plate, and further limiting the electron microscope through the adjustment plate. When the position of the electron microscope is adjusted, it is convenient to observe the left eye or the right eye of the patient, thereby facilitating surgery on both eyes of the patient.

[0017] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0018] Beneficial effects: In the present invention, the support mechanism is provided, and the electron microscope can be rotatably supported by connecting the threaded support rod and the support plate, so that when the electron microscope is used to photograph the patient's eyeball, the angle of the electron microscope can be adjusted, so that the adjusted angle of the electron microscope can correspond to the position of the patient's eyeball, and the adjustment plate and the slide rail are slidably connected, so that the position of the electron microscope can be conveniently adjusted, so that the left eye or the right eye of the patient can be photographed, so that good convenience can be provided when performing surgery on the patient; In the present invention, the eyelid stretching mechanism is provided, after the two eyelid stretching plates are sterilized in advance, the insertion rod can be inserted into the clamping ring, and then the positioning screw can be twisted to insert one end of the positioning screw into the positioning groove to achieve connection with the insertion rod, and the first connecting frame is laterally slidably connected with the supporting ring through the first slide plate, and the positions of the two eyelid stretching plates can be adjusted by moving the first connecting frame according to actual needs, and after the adjustment is completed, the first clamping rod is released, and the first tension spring in a stressed state can drive the first clamping rod to be inserted downward into the corresponding clamping groove, so that the first connecting frame can be limited, and the gooseneck tube itself has plasticity, so it can be conveniently bent, so that the positions of the two eyelid stretching plates can be adjusted, so that the two eyelid stretching plates can be aligned with the patient's eyes, and then the two eyelid stretching plates can be moved away from each other by operating the threaded assembly, so that the patient's eyelids can be stretched, so that it is convenient for doctors to perform surgery on the patient's eyes; In the present invention, the position of the laser pen can be adjusted by horizontally moving the second connecting frame through the setting of the marking mechanism. At this time, the position of the laser pen can be adjusted according to the position of the patient's eye, and after the position of the laser pen is adjusted, the second clamping rod can be released, and the second tension spring in a stressed state can pull the second clamping rod to move downward, so that the second clamping rod is clamped with the corresponding clamping slot, and then the position of the laser pen can be adjusted by operating the rotating component, so that the light emitted by the laser pen can be aimed at the affected part in the patient's eye, thereby marking the surgical position.

[0019] In actual use, the present invention can be used to photograph the patient's eyes with an electron microscope to assist doctors in performing surgery on patients, thereby facilitating the opening of the patient's eyelids and marking the affected area of ​​the patient's eyeball. Figure 1 Because of the design of multiple laser pens, the laser pens can not only irradiate the patient's area, but also irradiate the entry position of the incision for eye surgery. Specifically: plan the entry position of the surgical incision into the eye in advance, and then use the corresponding laser pens to irradiate the corresponding surgical incision position. During the operation, the doctor can perform high-precision surgery based on the irradiated laser position, which improves the success rate of the operation and provides good convenience for the doctor.

[0022] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0024] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] In the embodiments of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0026] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present invention. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0027] Example 1: Reference Figure 1-7 , an imaging device, including a main body of the device consisting of a vertical electric guide rail 1, a horizontal electric guide rail 2 is firmly installed on the vertical electric guide rail 1, and an arc-shaped electric guide rail 3 is further installed on the horizontal electric guide rail 2. The end of the arc-shaped electric guide rail 3 is fixedly connected to a mounting rod 4. On this basis, we have added the following key components: like Figure 3 and Figure 4As shown, the electron microscope 20 is installed at the bottom of the mounting rod 4 through the support mechanism thereon. The support mechanism is constructed in detail as follows: the fixing frame 5 is fixed to the bottom end of the mounting rod 4, and a threaded support rod 6 is rotatably connected to the inner wall of one side of the fixing frame 5. A support plate 7 is fixedly sleeved on the threaded support rod 6, and a slide rail 12 is fixed on one side of the support plate 7. On the slide rail 12, we slidably connect the adjustment plate 13, and fix the electron microscope 20 on one side of the adjustment plate 13. In order to facilitate the doctor's observation, we fix the support frame 19 on the top of the adjustment plate 13, and the two electronic limit mirror observation ports 21 are firmly mounted on the support frame 19, so that the doctor can directly observe the image taken by the electron microscope 20 through the electronic limit mirror observation ports 21. One end of the threaded support rod 6 penetrates the fixing frame 5 and extends to the outside thereof, and a brake assembly is connected there. The brake assembly includes a first rubber ring 8 fixedly mounted on one side of the fixing frame 5, and the threaded support rod 6 penetrates the first rubber ring 8, and a fixing bolt 9 located on the outside of the fixing frame 5 is provided on the threaded sleeve. A second rubber ring 10 is fixed to one side of the fixing bolt 9, and the second rubber ring 10 can be in active frictional contact with the first rubber ring 8. A handle 11 is also fixed to the fixing bolt 9. When we need to adjust and fix the angle of the electron microscope 20, we only need to rotate the fixing bolt 9 through the handle 11, and the second rubber ring 10 will approach the first rubber ring 8 under the action of the threaded transmission until the two are tightly fitted, thereby braking the threaded support rod 6, thereby fixing the angle of the electron microscope 20.

[0028] In order to enhance the stability of the electron microscope 20, as Figure 3 and Figure 4 As shown, we have rotatably connected the connection cover 14 on the top of the support plate 7, and the inner walls on both sides of the connection cover 14 are provided with sliding holes, and the connection plate 15 is slidably connected inside. One side of the connection plate 15 extends to the top of the adjustment plate 13 and is rotatably connected to the adjustment plate 13, and the other side is fixed with a limit plate 16, and the limit plate 16 passes through the sliding hole and extends to both sides of the connection cover 14. On one side of the limit plate 16, we symmetrically fixedly installed the first magnet 17 located on both sides of the connection cover 14, and the second magnet 18 is fixed on both sides of the connection cover 14, and the first magnet 17 and the second magnet 18 can attract each other. In this way, when the adjustment plate 13 drives the electron microscope 20 to move to the desired position, the first magnet 17 and the second magnet 18 will automatically attract each other to further fix the position of the electron microscope 20.

[0029] In addition, if Figure 3 As shown, we also fixedly set a support ring 22 on the electron microscope 20, the top of the support ring 22 is provided with a first annular groove 23, the side is provided with a second annular groove 25, and the top is provided with a plurality of slots 24 at equal intervals. These designs are all for the subsequent connection and fixing of the eyelid opening mechanism and the marking mechanism.

[0030] like Figure 5 and Figure 7 As shown, the eyelid stretching mechanism is composed of two eyelid stretching plates 38, which are used to support the upper and lower eyelids of the patient respectively. The two eyelid stretching plates 38 are connected to the support ring 22 through an adjustment component. The specific structure of the adjustment component is as follows: in the first annular groove 23 and the second annular groove 25, we slidably connect the first slide plate 26, one side of the first slide plate 26 extends to the outside of the support ring 22 and is fixed with a first connecting frame 27. A gooseneck tube 30 is fixed to the bottom of the first connecting frame 27, and a plug rod 31 is fixed to the bottom end of the gooseneck tube 30. In addition, we also have a mounting plate 32, a clamping ring 33 is fixed on the top, and a positioning screw 34 is threadedly connected on one side of the inner wall of the clamping ring 33. The bottom end of the plug rod 31 can extend into the clamping ring 33 and be clamped with the inner wall of the clamping ring 33. At the same time, a positioning groove 35 is also opened at the bottom of one side of the plug rod 31, and one end of the positioning screw 34 can extend into the positioning groove 35 and be clamped with its inner wall. A mounting frame 36 is fixed on one side of the mounting plate 32, and a threaded assembly is installed in the mounting frame 36, which is connected to the two eyelid opening plates 38. The top of the first connecting frame 27 also extends to the top of the support ring 22, and is fixed with a first arc-shaped slide 44, the bottom of which extends into the first annular groove 23 and is slidably connected to the inner wall of the first annular groove 23. On the top inner wall of the first connecting frame 27, we have penetrated and slidably connected the first clamping rod 28, which can be movably clamped with multiple clamping grooves 24, and a first tension spring 29 located above the first connecting frame 27 is also sleeved thereon. The top and bottom ends of the first tension spring 29 are fixedly connected to the top of the first clamping rod 28 and the top of the first connecting frame 27, respectively. When in use, the insertion rod 31 is inserted into the clamp ring 33, and the positioning screw 34 is twisted so that one end is inserted into the positioning groove 35 to achieve connection with the insertion rod 31. Then, the positions of the two eyelid stretching plates 38 are adjusted by moving the first connecting frame 27. After the adjustment is completed, the first clamping rod 28 is released, and the first tension spring 29 drives the first clamping rod 28 to be inserted downward into the corresponding clamping slot 24 to limit the first connecting frame 27. Since the gooseneck tube 30 is plastic, it can be easily bent so that the two eyelid stretching plates 38 are aligned with the patient's eyes. Afterwards, the two eyelid stretching plates 38 are moved away from each other by operating the threaded assembly (specifically, rotating the bidirectional screw 39 to drive the two threaded plates 37 away from each other), thereby stretching the patient's eyelids.

[0031] The present application can be used in the field of medical device technology, and can also be used in other fields applicable to the present application.

[0032] Example 2: Reference Figure 8 and Fig. 9, improved on the basis of the first embodiment: a microscope imaging device for ophthalmic surgery, which is applied to the field of medical device technology, the marking mechanism includes a mounting assembly connected to the support ring 22, the marking mechanism is set to multiple, and the assembly is connected to a laser ray pen 47 for irradiating and marking the diseased part in the patient's eyeball. The mounting assembly is specifically constructed as follows: in the second annular groove 25, we slidably connect the second slide plate 40, one side of the second slide plate 40 extends to the outside of the support ring 22 and is fixed with a second connecting frame 41. The bottom of the second connecting frame 41 is provided with a connecting groove, and a rotating member is installed inside, one side of the member extends into the second connecting frame 41 and is connected to the laser ray pen 47, and the other side extends to one side of the second connecting frame 41 and is connected to one side of the second connecting frame 41. The top of the second connecting frame 41 extends to the top of the support ring 22, and is fixed with a second arc-shaped slide bar 53, the bottom of the second arc-shaped slide bar 53 extends into the first annular groove 23 and is slidably connected to the inner wall of the first annular groove 23. On the top inner wall of the second connecting frame 41, we have slidably connected the second clamping rod 42. The bottom end of the second clamping rod 42 can be movably clamped with a plurality of clamping slots 24, and a second tension spring 43 is sleeved thereon and is located above the second connecting frame 41. The top and bottom ends of the second tension spring 43 are fixedly connected to the top of the second clamping rod 42 and the top of the second connecting frame 41, respectively. When in use, the position of the laser ray pen 47 is adjusted by moving the second connecting frame 41 laterally. After the adjustment is completed, the second clamping rod 42 is released, and the second tension spring 43 will pull the second clamping rod 42 to move downward and clamp into the corresponding clamping slot 24. Afterwards, the angle of the laser ray pen 47 is adjusted by operating the rotating component (specifically, pulling the pull plate 50 longitudinally to drive the adjustment rack 49 to move longitudinally, and then driving the gear frame 46 to rotate) so that the light emitted by it is aimed at the affected area in the patient's eye to mark it. Please refer to the attached figure. Figure 1 , because there are multiple laser ray pens 47, the laser ray pen 47 can not only irradiate the patient's site, but also irradiate the position of the incision for eye surgery. Specifically, plan the position of the surgical incision entering the eyeball in advance, and then use the corresponding laser ray pen to irradiate the corresponding position of the surgical incision. During the operation, the doctor can perform high-precision surgery according to the irradiated laser position to improve the success rate of the operation. After the marking is completed, since the inner friction ring 51 is fixed on both sides of the gear frame 46, and the outer friction ring 52 is fixed on the inner wall of both sides of the connecting groove, one side of the inner friction ring 51 can extend into the corresponding outer friction ring 52 and rub with the inner wall of the outer friction ring 52, so the gear frame 46 can be braked, and then the position of the laser ray pen 47 can be fixed. The light intensity emitted by the laser ray pen 47 is Class 1 (Class I) laser: This is the safest type of laser, and its radiation level is considered harmless under normal operating conditions. Lasers of this level will not cause harm because their power is very low.
