Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0047] like Figure 1-2 As shown, a prosthetic with an elbow device according to an embodiment of the present invention is an example of a full arm and shoulder prosthesis, which is suitable for being installed on the trunk 11 of the human body 1 from an amputation area to the scapula. In this embodiment, the human body 1 is taken as an example with a missing left arm and left shoulder, and the torso 11 has a shoulder 111 on the left side. The prosthesis 200 is an example of a left arm and s...

The invention discloses an artificial limb with an elbow joint device. The artificial limb comprises a connecting frame, a pivoting frame and a rotating frame, wherein the pivoting frame is rotatablyconnected to the connecting frame in a pivoted manner and is in pivoted rotation relative to the connecting frame around a first axis; the rotating frame is in sliding contact with the connecting frame; a driving mechanism is arranged between the pivoting frame and the rotating frame, and is used for driving the rotating frame to rotate relative to the pivoting frame around a second axis; and whenthe rotating frame rotates around the second axis, the rotating frame can be guided by the connecting frame to drive the pivoting frame to in pivoted rotation around the first axis through the driving mechanism, so that the rotating frame can rotate between a downward position facing downwards and a lifting position on one side of the connecting frame. The artificial limb disclosed by the invention has the beneficial effects that a toggle switch can be switched to different states to control the rotating frame of the elbow joint device to lift or fall, so that the using convenience can be added; a user can conveniently place foods in the mouth or view a cell phone; and besides, when a toggle rod is toggled to a releasing position, the inconvenience to the user when the rotating frame is hung in the air can be overcome.
Description
technical field [0001] The invention relates to the field of artificial limbs, in particular to an elbow joint device that can be rotated through control, and relates to a prosthetic limb with an elbow joint device. Background technique [0002] People with arm disabilities will install full-arm prostheses to replace the original function of the arm to reduce the inconvenience in daily life and work. [0003] Existing full-arm prostheses generally include an elbow joint, and an upper arm and a lower arm connected to the elbow joint. The elbow joint uses a motor as a power source, and drives the lower arm to rotate upwards or downwards through a transmission mechanism to pick up or place objects. For example, when taking food through the lower arm or taking a mobile phone to watch, the items taken by the lower arm usually have to be able to approach the user's face inward, so that the user can conveniently put the food in the mouth or Is to watch the phone. Therefore, the ...
