Universal Micro Rotary Object Holder

Abstract

Provided is a universal trace rotary holding device. The lower end of a handle is fixedly connected with one end of a locating pull rod; the locating pull rod is sleeved with a set of gear rings which are meshed; the outer gear ring is fixedly connected with the lower end of the handle; the inner gear ring is fixedly connected with the upper end of a clamp; a return spring is arranged inside the inner gear ring; the locating pull rod is sleeved with the return spring; the inner gear ring is movably connected with the end of the locating pull rod; the clamp is a fork-shaped structure; a locking ring is arranged on one side of the clamp; a pin shaft at one end of the locking ring is inserted on fork teeth of one side of the clamp. The holding device can help a patient with the poor hand fine function hold objects, the directions of the held objects can be adjusted at will, the requirement for changing the object holding directions by forward rotating and backward rotating of the front arms of the patient is met, operation is convenient, cost is low, the structure is ingenious, and the requirements for daily holding activities of patients who only have a certain grabbing capacity but are poor in fine function caused by cerebral apoplexy, cerebral trauma, spinal cord injury, upper limb nerve injury, hand injury and the like or disabilities with the forward rotating and backward rotating function of the front arms are met.

Description

technical field [0001] The invention relates to a power-assisted object holder, specifically a universal micro-rotating object holder used by patients with weak hands to assist in grasping objects in daily life, especially suitable for stroke, traumatic brain injury, spinal cord injury, upper limb peripheral Nerve injury, hand trauma, etc. have certain grasping ability, but poor fine function or dysfunction of forearm pronation and supination. Background technique [0002] With the development of the biological-psychological-social medical model, people gradually pay attention to the quality of life. However, for stroke, traumatic brain injury, spinal cord injury, upper limb peripheral nerve injury, hand trauma, etc., it only has a certain grasping ability. Poor function or dysfunction of forearm pronation and supination not only affects the patient's own function, but also directly affects the patient's daily life activities and quality of life. For example, the patient ca...

Problems solved by technology

[0002] With the development of the biological-psychological-social medical model, people gradually pay attention to the quality of life. However, for stroke, traumatic brain injury, spinal cord injury, upper limb peripheral nerve injury, hand trauma, etc., it only has a certain grasping ability. Those with poor function or forearm pronation and supination dysfunction not only affect the patient's own function, but also directly affect the patient's daily life activities and quality of life

For example, the patient cannot hold the tableware stably due to poor hand fine function, or cannot control the direction of eating well during the eating process, which greatly affects the daily life of the patient.

Temporary or permanent inability to perform fine movements of the hands not only brings a lot of trouble to the patients themselves but also to their families, which is a major problem that plagues patients and their families
