Bionic prosthetic mechanical foot

Abstract

The invention provides a bionic prosthetic mechanical foot. The bionic prosthetic mechanical foot comprises a leg fixing tube, a sticking chain, a hinged support A, a compression springs, a semicircular bracket and the like, and is characterized in that the leg fixing tube is a conical tube with a big upper opening and a small lower part; a semiarc groove is formed in the side surface of the tube; the sticking chain is mounted inside the semiarc groove; one end of the sticking chain is hinged to one end of the arc groove, and the other end of the sticking chain runs through a clamping buckle arranged at the other end of the arc groove; the bottom of the leg fixing tube is fixedly connected with a swing rod through two cylinders; the middle position of the swing rod is hinged to the upper end part of the hinged support A; the lower end of the hinged support A is fixed to a rectangular flat plate. Through arrangement of a connecting rod mechanism, the contact area between the mechanical foot and the ground surface can be increased, and the stability of the mechanical foot is enhanced; when a patient lifts up the mechanical foot, a front paw and a rear paw return to the state of 150-degree included angle under the actions of tension springs and toes are also lifted up to form an arch, so that walking of the patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bionic artificial limb mechanical foot. Background technique [0002] For some patients with amputations from the feet, the inability to walk normally will bring great inconvenience to their daily life. Most of the traditional prosthetics are integral structures, and the feet cannot be as flexible and convenient as human feet. The main reason is that The human foot is arched, and its toes have the ability to move and support, so we need a bionic mechanical foot to satisfy patients' desire for highly flexible prosthetics. Contents of the invention [0003] In view of the above problems, the present invention provides a bionic prosthetic mechanical foot. The present invention can make the mechanical foot swing left and right within a certain angle by setting a swing rod and a compression spring, which is beneficial to protect the patient's lower leg. By setting a linkag...
