Definitions

  • the Protective Circumcision Device The Protective Circumcision Device
  • This invention relates to a set of disposable surgical tools for circumcision.
  • the foreskin is a continuation of skin from the shaft of the penis, forming a fold that covers the glans penis and the urethral meatus.
  • the inner foreskin and the outer foreskin are continuous with each other and also freely mobile with respect to each other.
  • the foreskin is attached to the glans by the frenulum, which acts like a bridge between the glans and the inner skin of the foreskin fold.
  • the frenulum is highly vascular and carries some of the blood supply to the glans.
  • the inner foreskin and glans require regular cleaning to ensure adequate penile hygiene, as they contain glands that secrete an oily substance called smegma. There is a potential for these secretions to accumulate between the inner foreskin and glans, forming a potential environment for proliferation of naturally found bacteria on the skin, resulting in a bad smell.
  • Difficulties in maintaining good penile hygiene may contribute to the risk of infection among uncircumcised men.
  • Circumcision is the most common surgical procedure, and it involves the use of many instruments.
  • the device has a proximal end, a distal end, an inner recess, and an outer surface.
  • the inner recess opens from the proximal end and is designed to receive the glans of a penis.
  • the foreskin is pulled over the outer surface until it reaches a predetermined indicator, which provides a visual guide to the level of circumcision.
  • One of the device’s limitations is that it requires the frenulum to be cut as a preliminary step before the circumcision procedure.
  • Another disadvantage of this device is that it necessitates two personnel to perform the circumcision procedure: one to pull the prepuce skin and the other to counteract by pushing the device.
  • This device has another shortcoming in that it does not respect the normal inclination of the glans over the shaft.
  • P. M. Fenton describes a circumcision device that uses the circular edge of the bell-shaped member to cut and promote hemostasis.
  • the device s bellshaped member is painted with a pressure-sensitive and heat-resistant adhesive to withstand high temperatures and pressure from repeated sterilization.
  • the device has some limitations: it is reusable and does not respect the normal anatomical inclination of the glans of the penis on the shafts. Additionally, premature cutting may occur before adequate compression of the skin of the prepuce, resulting in bleeding.
  • US Patent No. 119,180 by Goldstein et al. describes another circumcision clamp that consists of a plate, a metallic bell, an arm, and a nut.
  • the compression of the prepuce is achieved by applying pressure between the bell and plate.
  • the pressure is sustained for a while to achieve hemostasis before excision.
  • This clamp has some shortcomings. One of them is that the bell is separate from the clamp, which makes it possible to use the wrong size bell with the wrong size clamp. Another shortcoming is that if the crushing action of the clamp is released prematurely, bleeding will occur, and suturing will be needed. This makes the device unsuitable for anyone with a bleeding tendency.
  • WO 2011/007358 A2 describes a circumcision device that includes an inner ring with a circumferential groove, at least one capturing ring, and a hollow cylinder. First, the inner ring is fitted on the posterior end of the hollow cylinder, and the assembled inner ring, together with the hollow cylinder, is slid under the foreskin over the glans.
  • the capturing ring is then placed over the foreskin, tightly fitting into the circumferential groove of the inner ring, thereby compressing the foreskin along the circumferential groove and restricting blood supply to the foreskin at the compressed site.
  • the hollow cylinder is then removed, leaving the inner ring and the capturing ring on the penis.
  • This circumcision device does not have a feature that allows for holding and extending the foreskin during the circumcision procedure. It is almost impossible to keep the retractable foreskin in a static position to enable the correct placement of the capturing ring on the circumcision line.
  • Another shortcoming is device displacement, which occurs when the device slips off the foreskin due to erection, manipulation, or improper placement. This can cause incomplete circumcision or the application of compression in the wrong place (as in the glans) and may require surgical completion.
  • the objective of the invention is to provide an easy-to-use and reliable tool that produces a clean circumcision.
  • the tool is designed to be easy to practice with, and it is intended to make the process of circumcision more accessible and less intimidating for both patients and practitioners.
  • Another objective of the invention is to enable the performance of circumcision with visual protection of the glans penis.
  • Another objective of the present invention is to apply clamping pressure on a desired circumferential area of the prepuce, allowing for a good bloodless circumcision.
  • Another objective of the present invention is to provide a clean wound at the circumcised site without the need for dressing to be applied to it.
  • Another objective of the present invention is to provide a simple, easy, and fast-to-Learn tool for performers, making it suitable for rural and remote areas with a deficiency of trained personnel.
  • Another objective of the invention is to provide an innovative instrument that preserves and retains the frenulum, which is the bleeding point during a circumcision operation.
  • the invention provides another object with an angled clamping part that helps the performer to anatomically align the Circumcision scar with the shaft of the penis, taking into account the anatomical position of the glans with a mild inclination on the shafts of the penis.
  • Another objective of the present invention is to keep the cut ends of the circumcised Skin opposed together over the inner part of the device and stay in this Condition until healing with lesser Chance of formation of constriction ring to the glans after removal of the device.
  • Another objective of the device that it is made of plastic or similar materials, which are cost- effective to produce. It is sterilized and packaged in sterile packaging for single-use and disposal purposes.
  • the protective circumcision device consists of three members that co-function together to perform circumcision: the protective tube (A), the clamping cage (B), and the traction nut cap (C), as shown in FIG. 1 in pre-engagement status.
  • the protective tube (A) which is a hollow tube with two opened ends (1) and (2); the proximal end has a conical shape (6) concerning the fact that the anterior side length is shorter than the posterior side length.
  • the proximal part of the protective tube (6) has a circumferential marginal flange (9) that appears in the side view as a circumferential angled flange.
  • the body of the protective angled tube (5) has at least two circumferential constrictions (5") on the surface of the tube.
  • the distal part of the protective tube (3) has a circumferential threaded external surface (3").
  • the distal threaded part (3) has a longitudinal cut (7) at the diameter of the tube, which is limited to the distal part and does not extend to the body (5) and divides the distal part into two equal parts.
  • the proximal conical-angled part (6) of the protective tube has a small downward extension from the body of the tube at the anterior sector of the circumference (10) below the circumference marginal flange (9).
  • the downward extension (10) smoothly decreases in length beyond the flange until it disappears. It is limited to the anterior half sector of the proximal end circumference and has a groove with a curved apex (11) located at the center,
  • the protective angled tube has four inside projections (12) at the junction of the proximal conical part (6) and the body of the tube (5), which are connected to form a central circle to prevent proximal migration of the device.
  • FIG. 7 and 8 it shows the clamping cage (B) of the invention, which includes two circular plates (13) and (14) connected by two or three arms (17).
  • the two circular plates have two center openings, the distal opening (15) and the proximal opening (16).
  • the anterior connecting arm is shorter than the posterior arms.
  • the proximal circular plate (14) is angled in comparison to the distal circular plate (13).
  • the connecting arms have at least two constrictions (18).
  • the distance between the two circular plates at the back (posterior) half of the clamping cage is equal to the distance between the two flanges on the back (posterior half) of the protective tube.
  • the diameter of the opening at the center of the proximal circular plate (16) of the clamping cage is greater than the diameter of the conical part (6) of the protective tube but less than the diameter of the external circumferential flange (9).
  • the distal circular plate has a recess or notch (20) that faces the inside of the circular plate at the back (posterior) half of the circumference of the plate.
  • the anterior connecting arm is located in the center of the front (anterior) half of the clamping cage.
  • There is a small indicator (19) of the anterior direction of the device located at the center of the anterior half circumference of the distal circular plate, in line with the anterior connecting arm.
  • FIG. 10 shows the traction nut cap (C) that is circular and open on two sides (22) and (23).
  • the traction nut cap has inside threads (24) and holes (25) in half of its width. Each hole has a facing hole and is located on a plane that represents the diameter of the nut circle.
  • FIG. 15, 16, and 17 it shows the three members of the invention in engagement status, with the locker rod (26) being fired into the coupled holes (25) in the traction nut cap (C) and through the cut (7) in the protective tube (A).
  • a tying aid which is a half-circular rod with a small hole at the end of one side.
  • the thread can be attached through the hole and used to tie a ligature at the constriction around the stretched prepuce over the protective angled tube.
  • Tight engagement of the cap will provide upward movement of the protective tube, which results in constricting the prepuce between the proximal circumferential flange (9) of the protective tube and the proximal circular plate (14) of the clamping cage.
