Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic medical instruments, and more specifically to a U-shaped confocal microscope contact cap. Background Art

[0002] As a special living cytology detection technology, in vivo confocal microscopy uses laser as light source and has the advantages of high resolution (1μm) and high definition. Through continuous confocal scanning, it can clearly obtain images of tissues and cells in various layers of living bodies, and can accurately locate the depth of pathogens of infectious diseases and observe the tissues around pathogens. It is one of the important research methods for in-depth exploration of the pathological mechanism of diseases from the cellular level in clinical practice. It is now widely used in the examination of cornea, conjunctiva, meibomian glands and other ocular surfaces. Its unique intuitive and clear characteristics make it widely used in the diagnosis and severity assessment of various eye diseases. Because it can be non-invasively examined on patients, it has ended the situation in which pathological biopsies were required for patients in order to make a clear diagnosis, reducing the damage caused to patients by the examination.

[0003] Blepharitis, also known as "red eye rim", "rotten eye rim" or "rotten eye circles", is characterized by redness, erosion, eyelash loss, dirty eyelashes, etc., which cause patients' eyes to itch, burn, itchy, and repeatedly develop "styes" (commonly known as styes, medically known as blepharitis) and other discomforts, affecting up to 37%-47% of ophthalmological patients. The eyelid margin is the free edge of the eyelid (commonly known as the eyelid), which is the junction of the eyelid skin and the palpebral conjunctiva. Its structure includes: eyelash follicles, meibomian glands, sweat glands, blood vessels, etc. At present, there is no special inspection method for the eyelid margin in clinical practice. Due to its unique advantages, in vivo confocal laser microscopy has become a favorable choice for eyelid margin inspection. However, the current confocal laser microscope and contact cap are still limited in the process of eyelid observation. The contact cap used in the existing confocal laser microscope is a frustum-shaped one. This design provides a larger inspection surface, which is conducive to the inspection of larger areas of ocular surface tissues such as the cornea, conjunctiva, and meibomian glands. However, the current contact cap has great difficulty in checking the eyelid margin because the eyelid margin is long, soft and difficult to shape, and its contact area is relatively small and difficult to fix.

[0004] Therefore, it is particularly important to utilize the existing confocal laser microscope and improve its applicable inspection range. Currently, there is an urgent need for a confocal laser microscope contact cap to expand the inspection range of eye-related organs and avoid the discomfort and risks caused by pathological examinations. Utility Model Content

[0005] The utility model aims to overcome at least one defect of the above-mentioned prior art and provides a U-shaped confocal microscope contact cap for solving the problem that the long eyelid is not easy to fix, which leads to inconvenience in confocal laser microscope examination and high technical difficulty for operators.

[0006] The technical solution adopted by the utility model is a U-shaped confocal microscope contact cap, including a truncated cone-shaped contact head, the upper bottom surface of the contact head is a contact surface, and the contact surface is provided with an eyelid contact groove; a cavity is provided inside the contact head and opens toward the lower bottom surface of the contact head, and the bottom of the contact head is connected to a mounting portion.

[0007] The mounting portion is used to connect the U-shaped confocal microscope contact cap with the confocal laser microscope. The contact surface is in close contact with the patient's eye skin. The eyelid contact groove is used to fix the patient's eyelid. The U-shaped confocal microscope contact cap is fixed on the confocal laser microscope, and then the patient's eyelid margin is placed in the eyelid contact groove to fix the patient's eyelid, thereby preventing the patient from blinking or moving unconsciously during the examination so that the examination position is changed, which is more conducive to clear imaging of the confocal laser microscope, bringing a non-invasive, more comfortable, and repeated examination experience to the patient, which is conducive to more accurate diagnosis and treatment.

[0008] Furthermore, two ends of the eyelid contact groove penetrate the side surface of the contact head, and the eyelid contact groove is a strip-shaped groove with a curved side wall and a flat bottom, and the flat surface is the detection surface.

[0009] The detection surface fits the eyelid margin of the patient. The two ends of the eyelid contact groove penetrate the side of the contact head, which reduces the contact and pressure on the non-affected part of the patient's eye, relieves the patient's pain, and improves the comfort of the examination. The shape of the eyelid contact groove is convenient for completely fitting the patient's eyelid, which is conducive to full observation. The detection surface is a laser positioning area, which is used for positioning and detection. The position of the patient's eyelid can be accurately located through the detection surface, thereby improving the efficiency of the inspection.

[0010] Furthermore, the detection surface is a strip-shaped area parallel to the contact surface and located at the center of the contact surface.

[0011] Furthermore, the width of the detection surface is 1.5-2 mm.

[0012] This width can be adapted to the general eyelid width, allowing for complete observation of the patient's eyelids.

[0013] Furthermore, the width of the eyelid contact groove is 3-4 mm, and the depth is 3-4 mm; the wall thickness between the detection surface and the cavity is 0.5-0.7 mm, and the wall thickness between the rest of the outer surface of the contact head and the cavity is 0.75-0.85 mm.

[0014] The eyelid contact groove can provide sufficient accommodation space, deeply fit the patient's eyelid, and improve the accuracy of the examination result.

[0015] Furthermore, the contact surface and the edge of the eyelid contact groove are in a rounded transition.

[0016] Rounded corner transitions help protect patients, avoid compression or trauma caused by sharp edges, and reduce patient discomfort.

[0017] Furthermore, the mounting portion is a hollow cylindrical structure having the same radius as the bottom surface of the contact head.

[0018] The structure of the mounting portion can be well matched with the confocal laser microscope, so that the U-shaped confocal microscope contact cap is sleeved on the confocal laser microscope. Preferably, the contact head and the mounting portion are integrally formed.

[0019] Furthermore, the bottom end of the mounting portion extends outward to form a protruding annular hand-held portion.

[0020] The annular hand-held portion makes it easy for medical personnel to take the U-shaped confocal microscope contact cap without touching other parts, is convenient for installation and removal, and is beneficial to preventing contamination of the contact head surface and infection during use.

[0021] Furthermore, the radius of the contact surface is 6-7 mm, and the radius of the bottom surface of the contact head is 25-26 mm; the thickness of the annular hand-held portion of the mounting portion is 0.85-0.95 mm, and the thickness of the remaining parts of the mounting portion is 0.75-0.85 mm.

[0022] Furthermore, the U-shaped confocal microscope contact cap is made of polycarbonate, which has a high light transmittance and can clearly observe the structure of each layer of the patient's eyelid in conjunction with a confocal laser microscope, achieving a better inspection effect.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] The eyelid contact groove of the utility model fits the long eyelid, which plays a role in fixing the eyelid conveniently, quickly and stably, preventing unconscious blinking or movement during the examination so as to change the examination position, and is more conducive to clear imaging of the confocal laser microscope, bringing patients a non-invasive, more comfortable and repeated examination experience, which is conducive to more accurate diagnosis and treatment;

[0025] The two ends of the eyelid contact groove pass through the side of the contact head, which reduces the contact and pressure on the non-affected parts of the patient's eyes, alleviates the patient's pain, improves the comfort of the examination, and has good application prospects; the detection surface facilitates the determination of the position of the patient's eyelid during the examination, ensures the accuracy of the observation position, and cooperates with the confocal laser microscope to clearly observe the patient's eyelid, achieving better inspection results.

[0030] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, this embodiment is a U-shaped confocal microscope contact cap, including a truncated cone-shaped contact head 100, the upper bottom surface of the contact head 100 is a contact surface 110, and the contact surface 110 is provided with an eyelid contact groove 120; a cavity is provided inside the contact head 100 and is open toward the lower bottom surface of the contact head 100, and a mounting portion 200 is connected to the bottom of the contact head 100. The mounting portion 200 is used to connect the U-shaped confocal microscope contact cap with the confocal laser microscope. The contact surface 110 is in close contact with the eye. The eyelid contact groove 120 is used to fix the patient's eyelid. The U-shaped confocal microscope contact cap is fixed on the confocal laser microscope, and then the patient's eyelid margin is placed in the eyelid contact groove 120, so that the patient's eyelid is fixed, and the unconscious blinking or movement during the examination process is prevented to change the examination position, which is more conducive to the clear imaging of the confocal laser microscope, and brings a non-invasive, more comfortable, and repeated examination experience to the patient, which is conducive to more accurate diagnosis and treatment. The wall thickness between the contact surface 110 and the cavity is 0.5-0.7 mm.

[0033] The two ends of the eyelid contact groove 120 pass through the side of the contact head 100. The eyelid contact groove 120 is a strip-shaped groove with an arc-shaped side wall and a flat bottom. The flat surface is the detection surface 121. The detection surface 121 fits the eyelid margin of the patient. The two ends of the eyelid contact groove 120 pass through the side of the contact head 100, which reduces the contact and pressure on the non-affected part of the patient's eye, alleviates the patient's pain, and improves the comfort of the examination. The shape of the eyelid contact groove 120 is convenient for fully fitting the patient's eyelid, which is conducive to full observation. The detection surface 121 is a laser positioning area used for positioning and detection. The position of the patient's eyelid can be accurately located through the detection surface 121, thereby improving the inspection efficiency.

[0034] The width of the eyelid contact groove 120 is 3 to 4 mm, and the depth is 3 to 4 mm. The eyelid contact groove 120 can provide sufficient accommodation space, deeply fit the patient's eyelid, and improve the accuracy of the inspection result. The detection surface 121 is a strip area parallel to the contact surface 110 and located in the center of the contact surface 110. The width of the detection surface 121 is 1.5 to 2 mm. This width can adapt to the general eyelid width, and the patient's eyelid can be fully observed.

[0035] like Figure 1 As shown, the contact surface 110 and the edge of the eyelid contact groove 120 are rounded. The rounded transition is beneficial to protecting the patient, avoiding compression or trauma caused by sharp edges, and alleviating the patient's discomfort.

[0036] like Figure 1 and 3 As shown, the mounting portion 200 is a hollow cylindrical structure with the same radius as the bottom surface of the contact head 100. The structure of the mounting portion 200 can cooperate well with the confocal laser microscope, so that the U-shaped confocal microscope contact cap can be mounted on the confocal laser microscope. The bottom end of the mounting portion 200 extends outward to form a protruding annular hand-held portion 210. The annular hand-held portion 210 is convenient for medical staff to take the U-shaped confocal microscope contact cap without touching other parts, which is convenient for installation and disassembly, and is conducive to preventing contamination of the surface of the contact head 100 and infection during use. A fastening structure, such as a threaded structure, can be provided on the inner side of the mounting portion 200, which can stably fix the U-shaped confocal microscope contact cap on the confocal laser microscope to prevent it from falling off, and also ensure that the installation position of the U-shaped confocal microscope contact cap is accurate and improves installation efficiency.

[0037] like Figure 1 As shown, the radius of the contact surface 110 is 6-7 mm, and the radius of the bottom surface of the contact head 100 is 25-26 mm. Figure 3As shown, the wall thickness between the detection surface 121 and the cavity is 0.6 mm, and the wall thickness between the remaining parts of the outer surface of the contact head 100 and the cavity, except for the detection surface 121, is 0.8 mm. The thickness of the annular hand-held portion 210 is 0.9 mm, and the thickness of the remaining parts of the mounting portion 200, except for the annular hand-held portion 210, is 0.8 mm. The height of the contact head 100 is 9 mm, and the height of the mounting portion 200 is 6 mm.

[0038] The contact head 100 and the mounting portion 200 are integrally formed. The U-shaped confocal microscope contact cap is made of polycarbonate, which is transparent as a whole, easy to transmit light, improve the brightness of the image obtained by the microscope, and facilitate observation of the various layers of the patient's eyelid structure; it is also convenient to observe from the outside whether the U-shaped confocal microscope contact cap is correctly installed and whether there are contaminants.
