Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary equipment, in particular to an arm support frame for ophthalmic fundus laser and an operation method. BACKGROUND

[0002] In ophthalmic treatment operations, especially during fundus laser treatment, doctors need to maintain a specific posture for a long time to ensure the accuracy of laser operation. Usually, the doctor's left hand needs to be fixed in contact with the contact lens for a long time in order to stabilize the patient's eyeball. This operating environment puts high demands on the physical fitness and operation stability of the doctor. However, the existing arm support equipment still has many shortcomings in meeting these needs, mainly in the following aspects:

[0003] Most of the arm support frames on the market adopt a fixed structure, and the doctor cannot adjust the angle and height of the arm support during laser operation. Because the support position is fixed, the doctor needs to frequently fine-tune the arm posture during operation, which increases the difficulty and fatigue of the doctor's operation, and over time, it is inevitable to cause shoulder and neck pain, and induce and aggravate cervical spondylosis. If the doctor needs to change the support position, he usually needs to manually loosen or replace the fixed parts, which not only takes time, but also easily interrupts the operation process, affecting the efficiency and effect of the laser.

[0004] Traditional arm support equipment often causes discomfort to doctors due to lack of comfort in long-term use. Existing equipment often uses hard materials to directly support the doctor's arm, lacking comfort design. When the doctor needs to maintain a stationary posture for a long time during laser operation, the fixed hard support will exert continuous pressure on the arm, causing local pain or discomfort. This not only affects the doctor's concentration, but also can cause hand fatigue, thereby affecting the precision and safety of the laser.

[0005] In fine ophthalmic operations, the doctor's operation often needs to have high flexibility. However, most of the existing arm support frames lack fine-tuning functions and can only provide a fixed support angle and position. This makes it impossible for the doctor to accurately adjust the arm position during operation according to the actual situation, affecting the flexibility of the operation. At the same time, due to the lack of effective adjustment mechanism, the doctor may need to rely on his own arm strength to adjust the posture when fine-tuning, which increases the difficulty of the operation.

[0006] Some existing arm support frames are designed to be relatively bulky in order to improve stability. Although such designs can provide relatively stable support to a certain extent, the bulky device requires more time and effort for the doctor to prepare and adjust before laser operation. If the height or angle of the support frame needs to be adjusted quickly during the operation, it will be inconvenient due to the difficulty of adjustment. In addition, the large size of the support frame occupies more operating table space and increases the difficulty of cleaning and maintenance.

[0007] In ophthalmic diagnosis and treatment operations, different doctors may have different needs for support equipment, but most of the support equipment on the market has a single structure design and cannot meet the needs of different ophthalmic clinical diagnosis and treatment scenes. For example, some equipment is only suitable for specific types of ophthalmic surgery and operation, and cannot be adjusted modularly according to specific requirements. Such single design limits the applicability of the equipment in different surgeries and operations, resulting in the need for some doctors to use multiple devices in different surgeries and operations, which not only increases the cost of equipment, but also affects the overall efficiency of the surgery and operation.

[0008] In order to ensure the accuracy of surgery and operation, the doctor's arm needs to be kept stable during operation. However, the existing arm support frame lacks a reliable stability adjustment mechanism. For example, some devices may shake when adjusting the angle or height due to insecure fixation, affecting the stability of the support. In addition, there is a lack of effective buffer design in the support frame, and when the doctor makes a small adjustment, the stability of the support frame is difficult to guarantee, which may cause unnecessary displacement of the support frame during adjustment, affecting the operation accuracy of the surgery.

[0009] In summary, the arm support equipment for ophthalmic surgery and operation on the market has certain limitations in flexibility, comfort, fine adjustment ability, adjustment convenience, adaptability and stability. How to design an arm support frame that can provide stable support, flexible adjustment and comfortable support is a problem to be solved in the field of ophthalmic medical auxiliary equipment.

[0035] Example two

[0036] Based on the basis of example one, threaded holes 13 are opened at the central position of the top of sliding plate 9, screws that are matched with threaded holes 13 are screwed into the inner walls of threaded holes 13, limiting holes 14 that are equidistantly distributed are opened on the top outer wall of positioning frame 7, the inner wall profile of limiting holes 14 is matched with the outer wall profile of screws, the sliding plate 9 is fixed on the specified position on the top of positioning frame 7 by screwing the screws into the inner walls of limiting holes 14, the distance between adjacent limiting holes 14 is 2 cm, the length of positioning frame 7 is 40 cm, the distance between the two ends of the top of arc-shaped supporting sheet 11 is 10 cm, and the height of the three springs 6 is 2 cm.

[0037] Example three

[0038] Based on Embodiment 1, a sealing plug 5 is fixedly provided on the top outer wall of the pneumatic push rod 2, and an air sleeve 4 is fixedly provided at the bottom center of the support base 3. The inner wall of the air sleeve 4 and the inner wall of the sealing plug 5 are interference-fitted. The sealing plug 5, which slides through the inner wall of the air sleeve 4, forms a sealed space, which has a buffering effect and helps to improve the stability of the doctor's arm support. A sponge pad 12 is adhered to the top outer wall of the arc-shaped support plate 11. The sponge pad 12 helps to improve the comfort of the present invention.

[0039] Example 4

[0040] Based on Embodiment 1, two guide sleeves 16 are fixedly provided on the top outer wall of the positioning base plate 1. Vertically upward guide rods 17 are slidably connected to the inner walls of the two guide sleeves 16. The top end of the guide rod 17 is fixedly connected to the bottom outer wall of the support base 3. The guide sleeves 16 and guide rods 17 help to improve the stability of the pneumatic push rod 2 in the process of lifting the support base 3.

Before use, the sliding plate 9 slides on the inner wall of the guide rail 8 to adjust the position of the three arc-shaped support plates 11 at the top of the positioning frame 7. Adjusting the position of the arc-shaped support plates 11 facilitates adjustment of the support area for the doctor's arm, making it easier for the doctor to operate. Fine-tuning of the doctor's arm is also possible during this process. When adjusting the position of the touch mirror on the patient's eyeball, as the doctor's arm tilts forward or backward during the support process, the three arc-shaped support plates 11 on the positioning frame 7 are subjected to force, and the three springs 6 at the bottom of the positioning frame 7 are compressed. The three springs 6 are compressed to different degrees due to different forces, which can adjust the tilt angle of the positioning frame 7, making it convenient for the doctor's arm to make fine adjustments and facilitating the doctor's operation. After the position of the three arc-shaped support plates 11 is adjusted at the top outer wall support part of the positioning frame 7, the bolts are rotated into the inner wall of the threaded hole 13 and screwed into the inner wall of the limiting hole 14 to fix the arc-shaped support plates 11 at the designated position at the top of the positioning frame 7.

[0043] The foregoing merely illustrates some exemplary embodiments of the application, and no doubt numerous modifications and alterations thereto will be apparent to those skilled in the art. Accordingly, the above description is intended for purposes of illustration only and should not be construed as limiting the scope of the application.
