Self-adjusting pressure applicator
View Patent ↗A self adjusting pressure applicator that can be used to retain tissue without causing injury to the tissue and that allows for repositioning of the retained tissue. Such a device can be used in conjunction with a circumcision clamp or other surgical instrument to ensure accurate positioning of the tissue prior to surgical manipulation. When used with a circumcision clamp such a device can ensure accurate removal of the desired amount of tissue resulting in improved surgical outcomes.
1. A self-adjusting pressure applicator comprising:
a monolithic ring component having a position adjustor that delineates a lower shaft from an upper shaft and a contact surface at an end of the lower shaft opposing the position adjuster;
wherein the position adjustor comprises an upper half sphere having a larger diameter than an adjacent smaller diameter of a lower half sphere to form a shoulder;
wherein the upper half sphere being directly connected to the upper shaft;
wherein the lower half sphere being directly connected to the lower shaft; and
a monolithic foreskin holder having a contact surface and a pair of opposing arms having deflectable free ends opposing the contact surface of the monolithic foreskin holder;
wherein the pair of opposing arms automatically deflect outward as they move down the upper half sphere towards the lower half sphere and automatically retract inward as the pair of opposing arms move down the lower half sphere towards the contact surface of the monolithic ring component;
wherein the shoulder prevents inadvertent movement of the pair of opposing arms of the monolithic foreskin holder up to the upper shaft opposing the contact surface of the monolithic ring component;
wherein a spring back force is automatically generated by the pair of opposing arms in contact with the lower half sphere when a deflected gap between the free ends of the pair of opposing arms is greater than an initial gap to maintain a substantially constant circumference pressure force on to the tissue disposed between the contact surface of the monolithic ring component and the contact surface of the monolithic foreskin holder without the intervention of a user after a single axial sliding motion to position the pair of opposing arms in contact with the lower half sphere,
whereby tissue disposed between the contact surface of the monolithic ring component and the contact surface of the monolithic foreskin holder is retained without causing injury to the tissue.
2. The applicator according to claim 1 wherein the substantially constant circumference pressure force ranges from about 50 to about 200 grams.
3. The applicator according to claim 1 wherein the monolithic ring component further comprises a shaft having an outer diameter and the monolithic foreskin holder further comprises a hollow cylindrical sleeve having an inner diameter, wherein the hollow cylindrical sleeve inner diameter is greater than the shaft outer diameter such that the monolithic ring component and monolithic foreskin holder are slidably movable along the common centerline.
4. The applicator according to claim 3 wherein the sleeve further comprises an outer diameter having at least one circumferential projection to form a grasping member, whereby a frictional condition is created between the user's fingers and outer diameter to allow for easy slideable movement of the second component relative to the first component.
5. The applicator according to claim 1 wherein the monolithic foreskin holder further comprises an outer diameter having at least one circumferential projection to form a grasping member, whereby a frictional condition is created between the user's fingers and outer diameter to allow for easy of slideable movement of the foreskin holder relative to the monolithic ring component.
