Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: an ophthalmic head - fixing and protecting device under a slit - lamp, comprising a base 1, a slit - lamp body 2 and a microscope 3 fixed on the base 1, and further comprising: two bottom fixing seats 4, support columns 5, outer rods 7, forehead abutting rods 8, connecting pieces 9, elastic bands 10 and head placement seats 11;

[0027] Two bottom fixing seats 4 are fixedly arranged at the bottom end of the base 1 and are located on one side of the patient; a support column 5 is vertically arranged at the top end of the bottom fixing seat 4; a head placement seat 11 is fixedly arranged at the top end of the support column 5; an outer rod 7 is fixedly arranged at the edge position of the top end of the head placement seat 11 and is coaxial with the support column 5; a forehead abutting rod 8 is fixed on the head placement seat 11 through two struts, the forehead abutting rod 8 is arc-shaped, the two struts are located inside the outer rod 7, and there is a gap between the two struts and the outer rod 7; a connecting piece 9 is sleeved on the outer wall of the outer rod 7 in a movable and detachable manner; an elastic band 10 is connected between the two connecting pieces 9, and the elastic band 10 is used to be arranged at the rear side of the patient's head.

[0028] In the ophthalmic slit lamp treatment head fixing and protecting device provided by the present application, the fixing effect of the patient's head during the examination and treatment process is ensured. Among them, the bottom fixing seat 4 is installed at the bottom end of the base 1, providing a stable support point for the whole device. The support column 5 is vertically installed on the bottom fixing seat 4 and extends upward to support the head placement seat 11, ensuring that the height of the head placement seat 11 is appropriate for the placement of the patient's head. The head placement seat 11 is located at the top end of the support column 5, providing a direct support platform for the patient's head. The outer rod 7 is coaxially fixed with the support column 5 at the top end of the head placement seat 11, increasing the stability of the device. Through its position and design, the connecting piece 9 provides an area for placement and movement, and at the same time enables the connecting piece 9 to be detached from the outer rod 7. When not in use, the whole connecting piece 9 and the elastic band 10 can be disassembled, or one side of the connecting piece 9 can be disassembled, so that all the connecting pieces 9 and the elastic band 10 can be hung together, without affecting the use of patients who do not need to fix their heads. The elastic band 10 is connected between the two connecting pieces 9, surrounds the rear side of the patient's head, provides the necessary fixing force, and prevents the head from moving unconsciously during the examination or treatment process.

[0029] When the patient is in place, the head placement seat 11 supports the patient's head, and the outer rod 7 and the forehead abutting rod 8 act together on the patient's forehead to provide a stable support point. The combination of the connecting piece 9 and the elastic band 10 surrounds the rear side of the patient's head, and the tightness of the band can be adjusted as needed to adapt to the head sizes of different patients, ensuring that the head remains stable during the whole examination or treatment process. It effectively solves the problem of interruption of examination or treatment caused by the movement of the patient's head, reduces the time for the microscope 3 to refocus, reduces the operation difficulty, and at the same time avoids the secondary injury that may be caused to the eyes due to head movement, improving the safety of diagnosis and treatment and the practicability of the slit lamp.

[0030] In some examples, furthermore, an adjusting screw column 6 is further provided on the outer wall of at least one support column 5. The adjusting screw column 6 is used to adjust the height position of the head placement seat 11. The structure of the adjusting screw column 6 in this example is a common configuration of this device, and its adjusting function can also be applied to this device. The detailed working process and structural principle can all refer to the adjusting screw column 6 in the prior art, so it will not be elaborated too much in this example.

[0031] In some examples, furthermore, the outer rod 7 is further provided with: a column body 71, a rounded corner portion 72, a flat portion 73, and a plurality of grooves 74. The column body 71 is the main part of the outer rod 7 and is located above the two end portions of the head placement seat 11; the rounded corner portion 72 is opened at the top edge portion of the column body 71; the flat portion 73 is arranged on the outer wall of the column body 71 in the vertical direction; the plurality of grooves 74 are equidistantly opened on the wall surface of the flat portion 73 in the vertical direction.

[0032] In this example, the column body 71 on the outer rod 7 is the main part of the outer rod 7. The rounded corner portion 72 opened at the top can make the connecting member 9 more smoothly sleeved on the outside of the column body 71 after being disassembled, facilitating the installation and disassembly of the connecting member 9 and reducing the damage to the inner wall of the connecting member 9; the setting of the flat portion 73 makes the outer wall of the column body 71 not an incomplete circular cross-section outer wall. Therefore, after the connecting member 9 is sleeved on the outer wall of the column body 71, the ability of the connecting member 9 to rotate on the column body 71 can be restricted by changing the shape of the connecting member 9, so that the connecting member 9 can only perform vertical lifting and lowering movements on the outer wall of the column body 71 to cope with different contact positions at the rear side of the brains of different patients, thereby achieving a better fixing effect. The setting of the grooves 74 is used to cooperate with the connecting member 9, so that the connecting member 9 will not easily move around on the column body 71, and a moving force is required to make the connecting member 9 move vertically, reducing the influence of gravity on the connecting member 9 and the elastic band 10.

[0033] In some examples, furthermore, the connecting member 9 includes: a sleeve 91, a limiting block 92, and a plurality of elastic pieces 93. The sleeve 91 can be detachably sleeved on the outer wall of the outer rod 7; the sleeve 91 can also be detached and separated from the outer rod 7, and the outer wall of the sleeve 91 is fixedly connected to the end of the elastic band 10; the limiting block 92 is fixedly arranged on the inner wall of the sleeve 91 and is correspondingly clamped with the position of the flat portion 73; the plurality of elastic pieces 93 are arranged on the inner wall of the limiting block 92. The elastic pieces 93 have an elastic protrusion that can be stretched and contracted, and the elastic protrusion can be clamped in the grooves 74. The middle part of the outer wall of the sleeve 91 is a winding outer wall 94, and the winding outer wall 94 is used to wind up the excess length of the elastic band 10. Shielding pieces are arranged at both ends of the winding outer wall 94.

[0034] In this example, the kit 91 serves as the main body part of the connecting member 9. A through hole is provided in the middle of the kit 91. Through the through hole, the kit 91 can be sleeved on the outer wall of the outer rod 7. After the kit 91 is sleeved on the outer rod 7, the position of the limiting seat provided on the inner side of the kit 91 corresponds to the position of the flat part 73 provided on the column body 71. The limiting seat also has an inner wall with a flat surface, and this flat inner wall fits against the flat part 73 on the column body 71 to restrict the rotation of the kit 91 around the column body 71, avoiding the automatic release of the kit 91 when the elastic band 10 with extra length is wound around the winding outer wall 94. Therefore, by restricting the rotation ability of the kit 91 and winding the elastic band 10 with extra length around the winding outer wall 94, the length and elastic effect of the elastic band 10 can be flexibly adjusted. Above the inside of the limiting seat, an elastic piece 93 is also provided, and the elastic piece 93 can be snapped into the groove 74 to enhance the ability of the kit 91 to stay on the outer wall of the column body 71 at a specified height.

[0035] In some examples, further, the distance between two adjacent elastic protrusions is the same as the distance between two adjacent grooves 74, so that multiple elastic protrusions within the same kit 91 can be snapped into multiple grooves 74 simultaneously, and a stronger staying effect can be achieved at any height on the outer wall of the column body 71, avoiding the influence of the movement of the patient's head on the position of the kit 91.
