Problems solved by technology

The fourth kind of prosthetic wrist can electrically drive the wrist to rotate, and can realize quick change. The structure of the parts is complicated, and there is a non-detachable structure, which is not convenient for the maintenance of the prosthetic wrist.
[0007] (1) Most electric prosthetic wrists do not have quick-change function
[0008] (2) The non-detachable structural design makes the maintenance of the prosthetic wrist difficult
[0009] (3) Wrist self-locking reliability is poor

Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] The prosthetic electric wrist rotation device is composed of a first-level mechanical transmission mechanism, a second-level mechanical transmission mechanism and an electrical slip ring mechanism; such as figure 1As shown, the drive motor 11 of the first-stage mechanical transmission mechanism is placed in the first-stage transmission casing 2, the center hole of the small end bracket 10 of the disc spring is sleeved on the neck of the output end of the motor 11, and the small end bracket of the disc spring 10 The flat end face is abutted against the end face of the output end of the motor 11, the central hole of the disc spring big end bracket 8 is coaxial with the central hole of the disc spring small end bracket 10, and the end face of the disc spring big end bracket 8 with multiple grooves is in line with the disc spring. The end faces of the small end bracke...

Abstract

The invention discloses an artificial limb electric wrist rotating device. The electric wrist rotating device comprises a first-stage transmission mechanism, a second-stage transmission mechanism and an electric slip ring mechanism, the first-stage transmission mechanism is a friction planetary transmission mechanism, the second-stage transmission mechanism is a two-stage gear planetary transmission mechanism, and the electric slip ring mechanism can realize quick connection and separation of the electric wrist rotating device and the prosthetic hand connection interface; and an eccentric shaft and a push rod mechanism of the second-stage transmission mechanism have reliable mechanical self-locking capability. The artificial limb electric rotating wrist is of a detachable structure and has the advantages of being simple in structure, reliable in work and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation equipment, in particular to a prosthetic electric wrist rotation device. Background technique [0002] The prosthetic hand is installed at the artificial wrist interface at the end of the forearm cavity of the disabled residual limb to realize some functions of the human hand. The prosthetic wrist products have various structural forms: the first is the fixed wrist, which does not have the rotational movement of the wrist, but only provides the connection interface between the prosthetic hand and the wrist, which is generally a fixed screw connection; The second type is an artificial rotating wrist, which can be twisted with a healthy hand to make a rotating movement, and the limited stop plate limits its rotation range; the third type is an electric wrist but does not have a quick-change function. The wrist has a motor and a deceleration mechanism, with a brush and a slip ring, and the rota...
