Design of semi-open prosthetic socket with constant force for lower limb.

Background: Prosthetic socket is a key component of the prosthesis for clinical application; its performance directly affects the adaptation of the residual limb to the prosthetic socket. There are long-term and short-term volume fluctuation of the residual limb. The volume fluctuation of the residual limb will lead to the pressure mismatch at the interface of the residual limb and the prosthetic socket, which will cause a series of skin and fit problems.

Current development and clinical applications of artificial anal sphincter.

Introduction: Fecal incontinence is a common chronic disease, which not only brings inconvenience to the lives of patients, but also causes great psychological harm to patients. Artificial anal sphincter is an innovative method that may treat fecal incontinence, and now has been clinically applied.

Areas Covered: This article will review recent developments in mechanisms and clinical applications of artificial anal sphincter.

Experimental assessment of a novel artificial anal sphincter with shape memory alloy.

Background: Fecal incontinence caused by sphincter dysfunction is a difficult medical problem that has not been fully resolved. The artificial anal sphincter provides a new therapeutic strategy for fecal incontinence. In order to solve the biomechanical compatibility problem between the artificial anal sphincter and intestinal tissue in clinical application, a design of constant force artificial anal sphincter was assessed in this paper.

Design of lower limb prosthetic sockets: a review.

Introduction: The prosthetic socket is the connecting part between the stump and the prosthesis, which is the important basis for the function of the prosthesis. The current prosthetic socket is difficult in meeting the needs of amputees current, which is the main reason for amputees abandoning their prostheses. This paper reviews the design and use of prosthetic sockets for lower limb.
