Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an arm support frame for ophthalmic fundus laser and an operating method thereof. Background Art

[0002] During ophthalmic treatment, especially 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 fix the contact lens for a long time to stabilize the patient's eyeball. This operating environment places high demands on the doctor's physical fitness and operating stability. However, the existing arm support equipment still has many shortcomings in meeting these requirements, which are mainly reflected in the following aspects:

[0003] Most arm supports on the market currently use a fixed structure, which makes it difficult for doctors to adjust the angle and height of the arm support during laser operation. Since the support position is fixed, doctors need to frequently fine-tune the arm posture during operation, which increases the difficulty and fatigue of doctors. In the long run, it is inevitable that they will suffer from shoulder and neck pain, induce and aggravate cervical spondylosis, etc. If doctors need to change the support position, they usually need to manually loosen or replace the fixed parts, which is not only time-consuming, but also easily interrupts the operation process, affecting the efficiency and effect of the laser.

[0004] Traditional arm support devices often cause trouble to doctors due to lack of comfort during long-term use. Existing devices often use hard materials to directly support the doctor's arm, which lacks comfort design. When the doctor needs to maintain a static posture for a long time during laser operation, the fixed hard support will exert continuous pressure on the arm, causing local tenderness or discomfort. This not only affects the doctor's concentration, but may also cause hand fatigue, thereby affecting the accuracy and safety of the laser.

[0005] In delicate ophthalmic operations, doctors often need to have high flexibility. However, most existing arm supports lack fine-tuning functions and can only provide a fixed support angle and position. This makes it impossible for doctors to accurately adjust the arm position according to actual conditions during the operation, affecting the flexibility of the operation. At the same time, due to the lack of an effective adjustment mechanism, doctors may need to rely on their own arm strength to adjust their posture when making fine adjustments, which invisibly increases the difficulty of the operation.

[0006] Some existing arm supports are usually designed to be bulky in order to improve stability. Although this design can provide relatively stable support to a certain extent, due to the bulkiness of the device, doctors need to spend more time and energy in the preparation and adjustment process before laser operation. If the height or angle of the support needs to be adjusted quickly during the operation, it is often difficult to adjust and cause inconvenience in operation. In addition, the support is large in size, taking up more space on the operating table, and also increasing the difficulty of cleaning and maintenance.

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

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

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