Description

Technical Field

[0001] The utility model belongs to the field of medical equipment technology, and in particular relates to a hand support frame used for upper limb adduction. Background Art

[0002] In some surgical operations that require microsurgery, doctors generally need to perform the operation for a long time and use a surgical microscope. The operation is complex and requires high precision. The surgeon needs to use both hands to operate the instrument during the operation, and the arm is always in a suspended state. The arm muscles are not supported and the arm is in a tense state for a long time, which is prone to fatigue and soreness, and seriously affects the accuracy of the operation. In view of this situation, an arm support is usually used to support the surgeon's arm. The existing arm support needs to be adjusted manually, which cannot meet the needs of adjustment at any time and requires the assistance of other people. Manual adjustment of the height may require medical staff to Using both hands to operate makes it impossible to perform other tasks at the same time, such as monitoring equipment or caring for patients, which reduces work efficiency. For occasions that require precise height adjustment, such as ophthalmic examinations or surgery, manual adjustment may not achieve the required accuracy, while electric control can provide more precise adjustment. In an emergency, the speed of manual height adjustment may not be as fast as electric adjustment, which may affect the timeliness of medical response. At the same time, the arm support plates and cushions of some existing arm supports are fixed. The arm support plates need to be replaced and maintained regularly. If they cannot be disassembled and replaced, it means that a large area needs to be disassembled when maintenance or replacement is required. This will increase the maintenance workload and reduce maintenance efficiency. If the cushion cannot be easily disassembled and replaced, it means that a large area needs to be cleaned and disinfected when maintenance or replacement is required, and the device cannot be used during this period. This will increase the maintenance workload and reduce maintenance efficiency.

[0003] In the publication number CN201609471 U, a hand support for upper limb adduction is disclosed, comprising a support frame, a roller is provided at the bottom of the support frame, a telescopic rod is provided on the support frame, and an arm support plate is fixed on the top of the telescopic rod; therefore, the hand support frame can be adjusted to a suitable height through the telescopic rod, and the doctor can place both arms on the arm support plate of the hand support frame to perform the operation. Since the hand support frame supports the arms, the fatigue of the doctor's arms is reduced, the stability of the arms is increased, the operation is convenient, and the high precision requirements of the operation are ensured. The utility model has a simple design, low cost, and significant use effect, and is convenient for accurate treatment of neurosurgeons.

[0004] However, the height of the above device needs to be adjusted manually, which cannot meet the need for adjustment at any time. Medical staff need to use both hands to operate it, so they cannot perform other tasks at the same time, such as monitoring equipment or caring for patients, thereby reducing work efficiency. At the same time, the arm support plate of the device is fixed on the lifting rod and cannot be disassembled and replaced, which means that when maintenance or replacement is required, the entire device needs to be replaced, which increases the cost of use. Therefore, in order to solve the above problems, a hand support frame for upper limb adduction is proposed. Utility Model Content

During the operation or treatment, medical staff can adjust the height directly through the foot pedal control without touching the hand support frame with their hands. This can reduce the burden on the hands and improve the efficiency of the operation. During the operation, it is very important to maintain a sterile environment. The foot pedal control can prevent medical staff from directly contacting the hand support frame, thereby reducing the possible risk of contamination. The foot pedal control can provide more precise height adjustment, ensuring that the patient's upper limbs are correctly placed in the most suitable position, which is conducive to the smooth progress of the operation. For medical staff who work for a long time, being able to adjust the height through the foot pedal can effectively reduce their labor intensity and avoid fatigue caused by frequent manual adjustment.

[0015] 2. The utility model is equipped with a supporting mechanism on the lifting mechanism, which can quickly adjust the arm rest according to different surgeries or the physical conditions of different users. During the operation, the doctor can easily adjust the inclination angle of the arm rest as needed to obtain the best surgical viewing angle and working space.
