Hand supporting plate for assisting ultrasonic examination

Abstract

The invention relates to the technical field of medical auxiliary instruments, and provides a hand supporting plate for assisting ultrasonic examination. The hand supporting plate comprises a hand-shaped supporting plate, wherein finger supports and a palm support are arranged on the hand-shaped supporting plate. The hand supporting plate overcomes the defects in the prior art, is reasonable in design, and solves the problems that in the existing ultrasonic examination process, fingers cannot complete the movement action by themselves, observation of an affected part is limited, and subsequent treatment is not facilitated. According to the hand supporting plate, the fingers are controlled to move through a gear mechanism, and secondary injuries caused by too large curvature are avoided; a shaft sleeve structure is matched with the gear mechanism to move, the fingers are not prone to being shielded when examined, and subsequent treatment is facilitated; the bending direction of the fingers can be controlled upwards or downwards according to the palm through a gravity sensing area, and accidental injuries are avoided; the finger supports are arranged in a finger-like structure, and bending and stretching are flexible; the movement of the finger supports can be controlled in a remote control mode, and use is convenient; the hand supporting plate can be used by the left hand and the right hand, and the cost is saved; and the hand supporting plate supports the hands of a patient stably in a supporting mode, the contact pain of the affected part is reduced, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a hand support for ultrasonic inspection assistance. Background technique [0002] In the past, the most common method of hand ultrasound examination was to let the patient place his hand directly on the examination area. When the doctor used the examination equipment to examine the diseased area, the doctor would ask the patient to lift his finger or move his hand to facilitate the examination. Generally, the thumb is not easy Block or be blocked. [0003] However, 1. Patients undergoing hand examination usually suffer from fractures, bone marrow edema, tendon injury, nerve injury, joint capsule injury, etc., and cannot complete activities by themselves. If external force is used rashly, it is easy to cause secondary injury to the affected area; [0004] 2. When the affected part of the patient is in the middle finger, especially for the injured part of the ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary hand support for ultrasonic examination, which overcomes the deficiencies of the prior art and has a reasonable design. Tendon injury, nerve injury, joint capsule injury and other problems make it impossible to complete activities on your own. If you use external force rashly, it will easily cause secondary injury to the affected area. If there is no flexible support body, the observation of tendons and joints is obviously limited, and the inspection imaging is unclear and incomplete, which is not conducive to the problem of follow-up treatment; the present invention arranges a gear mechanism on the hand-shaped support plate, the first gear and the second gear The meshing transmission of the two gears can slowly control the movement of the finger parts, avoiding secondary damage to the patient's hand caused by excessive bending; by setting the shaft sleeve structure to cooperate with the gear mechanism to move, the electromagnet is energized and contacts the transmission shaft, and the corresponding finger rest follows the transmission. The axis moves to do bending movement; the electromagnet is not energized and has no contact with the transmission shaft, and the corresponding finger rest has no movement; the affected part of the finger can be passively flexed and stretched in a suitable position to observe the tendon, joint, and ligament damage. The inspection image is clear and complete. It is beneficial to follow-up treatment; by setting the gravity sensing area, when the patient's palm is up, there is no gravity induction, and the gear mechanism controls the finger rest to bend upward; when the patient's palm is down, there is no gravity induction, and the gear mechanism controls the finger rest to bend downward, avoiding Accidental injury to the patient; the finger rest imitates the structure of the finger, and the pulley joint is formed between the two knuckles, which can be flexed and stretched between the knuckles, and the knuckles can be controlled flexibly; by setting a wireless signal receiving module, the motor can receive the signal from the external remote control device. The remote control signal realizes the remote control of the movement of the finger rest, which is convenient to use; the hinge between the palm rest and the forearm rest can be adjusted according to the use of left and right hands, and one device can be used for multiple purposes, saving costs; Painful to touch, good usability
