A novel method of second stage labor assistance at least includes: providing a flexible cord member at least having at a first end, a first securing article, and at least having at a second end, a second securing article; coupling the first securing article to at least one upper extremity of an expectant mother; coupling the second securing article to at least one upper extremity of a person assisting (“assistant”) the expectant mother with child birth, the assistant at least serving as an anchor; and the expectant mother pulling on the flexible cord member away from the assistant to supplement the contractions of the expectant mother's abdominal and pelvic floor muscles, and at least partially inducing the movement of a baby down the birthing canal.

A multipurpose retractor is disclosed for use in surgical operations. The retractor can also be used as a speculum. The retractor is made from metal plates, springs, strings, hinges, rods and a worm gear system. The retractor can expand from having a very small diameter to a very large diameter. And at the same time it can produce substantial force or pressure to keep any orifice, birth canal, surgical incision open steadily and stably. The retractor can be easily collapsed after use within seconds using a worm gear system. The worm gear system provides considerable mechanical advantage and allows for the contraction of the retractor with little applied force by the hand. It also allows for control of the retractor to remain in a certain diameter size. A locking mechanism applied to the gear system prevents the retractor from unfolding and therefore the retractor remains stable. The spring system provides the retractor to open completely with great force and remain open.

A birthing glove exposes portions of the finger and thumb, which may be covered by a regular surgical glove.

A cuff extends from the trank for covering at least a portion of the practitioner's forearm and an inflatable bladder is disposed over the inner wall of the trank adjacent to the back of the hand for inflation in order to expand behind the exposed fingers and thumb of the practitioner in order to dilate the birth canal and provide access to the head of the infant.

A device for assisting childbirth, preferably made of separate sheets of loosely knitted polypropylene loops. Each sheet has a control end, an opposite mouth end, and a pair of insertion arms attached to the edges of the sheets. The insertion arms of each sheet slidingly engage one another. Thus, one sheet may be inserted between the fetal head and the birth canal wall until it is properly placed about the fetal head. The second sheet can then engage the first sheet, sliding into position around the fetal head as well, thereby forming an elongated gripping member completely encircling the fetal head. A drawstring may be provided to assist in initiating traction. Thereafter, pulling on the gripping member will cause the loops to lengthen longitudinally and compress in their transverse dimension, causing the circumference of the gripping member to decrease and thereby grip the fetal head.
