Bridget Martinez and Donald Mario Robert Harker

CROSS REFERENCE

[0001] This application claims the benefit for priority purposes of U.S. Provisional Patent Application Serial No. 63/441,604, titled “CIRCUMCISION PROTECTION SYSTEM”, filed on January 27, 2023. This provisional application is incorporated herein by reference in its entirety.

BACKGROUND

[0002] Medical procedures on a penis include penis enlargement, circumcision, implantation in a penis, fix a bent penis (penile plication), fix penis fracture, vasectomy, vasectomy reversal, prostate biopsy, urolift, transurethral needle ablation, prostate procedures such as transurethral resection of the prostate (TURP) and transurethral incision of the prostate (TUIP), central line placement, and orchiopexy.

[0003] Circumcision of newborn males is common at least in the United States. A risk in these medical procedures, and particularly circumcision, is unintentionally injuring the patient such as nicking or cutting a femoral artery.

[0004] Accordingly, there is a need for an apparatus and a method that provides protection for a patient during a medical procedure on or proximate to a penis. Documents of interest are CN 202682170; CN21096269, US6580011, and US Publication No. 2012/0220912. SUMMARY

[0005] The present invention is directed to a system that provides protection to a patient during a medical procedure such as circumcision, the system comprising an apparatus and a method for using the apparatus.

[0006] The protection apparatus comprises a body, preferably a mesh, having an outer perimeter and a circular or oval opening therethrough, the opening having an edge. The opening is sized to comfortably fit a penis, and preferably has a diameter of from about 1 to about 1.5 inch. The outer perimeter has a diameter of from about 6 to about 10 inches. Preferably the mesh is made of wires about 0.5 to about 1.5 millimeters in diameter. The wires of the mesh are sufficiently close together that a scalpel pushed with a force of 20 Newtons cannot penetrate the mesh. Typically, the mesh is sufficiently flexible that the mesh can be doubled on itself.

[0007] Preferably the opening and the perimeter are both circular.

[0008] Preferably the edges of the opening and the perimeter are sufficiently smooth to not injure or irritate a patient during circumcision. However, for rough edges, a covering can be on the perimeter of the body, or the edge of the opening, or both.

[0009] In a method according to the present invention, the following steps can be performed:

[0010] (a) selecting an apparatus comprising a body having an opening therethrough, the opening being at or near the center of the body;

[0011] (b) placing the selected apparatus over the patient’s penis with the penis projecting through the opening and with the mesh proximate to the patient’s skin; and [0012] (c) after step (b) circumcising the projecting penis.

[0013] Stated another way, the apparatus is useful during a medical procedure proximate to or involving a penis and comprises a flexible body having an outer perimeter with an opening therethrough, the opening having a diameter of from about 0.2 to about 1.5 inch.

The outer perimeter of the body has a diameter of at least about 6 inches. The body is sufficiently strong that a No. 10 scalpel pushed with a force of 10 Newtons, preferably with a force of 20 Newtons, more preferably with a force of 15 Newtons, cannot penetrate the body. Since medical procedures can involve a needle, preferably the body is sufficiently strong that a 28 gauge needle pushed with a force of 10 Newtons cannot penetrate the body, and more preferably 28 gauge needle pushed with a force of 20 Newtons cannot penetrate the body, and most preferably the body is sufficiently strong that a 28 gauge needle pushed with a force of 15 Newtons cannot penetrate the body. It is desirable that the body is sufficiently strong that both the scalpel and needle, cannot penetrate, although it can be sufficient that the body resists such a force for either the scalpel or needle.

Size opening can depend on a particular application. Generally the opening is sufficient large that an infant penis having a circumference of 0.5 inch can project through the opening. The opening is typically centrally or near centrally located in the body. Preferably the body is a mesh. The mesh can have an aperture size of from about 0.02 mm to about .2 mm, and preferably a maximum of about 0. 16 mm. The mesh can be formed of wires having a di ameter of from about 0.02 mm to about 0. 15 mm, and preferably a maximum of about 0.12 mm. The mesh can be made of stainless steel with square shaped apertures of about 0.14 mm per side, a wire diameter of about 0.112 mm, 100 mesh per inch and open area between wires of about 30%, and a weight of about 0.6 Kg per square meter.

[0014] In a typical medical procedure on a patient the following steps are performed: [0015] A. select an apparatus comprising a flexible body having an opening therethrough sized at a minimum that an infant penis having a circumference of 0.5 inch can project through the opening;

[0016] B. placing the select apparatus over the patient’s penis with the penis projecting through the opening and with the body proximate to the patient’s skin; and

[0017] C. after step B performing the medical procedure such as a circumcision.

[0018] These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings, wherein:

[0019] Fig. l is a top plan view of an apparatus according to the present invention;

[0020] Fig. 2 is a top plan view of an apparatus according to the present invention that includes a covering on the periphery of the mesh and the edge of the penis opening; and;

[0021] Fig. 3 is a schematic view showing use of an apparatus according to the present invention.

DESCRIPTION

[0022] With regard to Fig. 1 an apparatus 10 useful during circumcision comprises a body 12, which can also be referred to as a substrate, having an outer perimeter 14 and an opening 16 therethrough. Preferably the opening is centrally located; thus, the apparatus is doughnut-shaped .

[0023] The perimeter has a diameter of at least about 6 inches, and typically from about 6 to about 10 inches to provide adequate coverage in the method described below. The opening 16 can be centrally located, but also be off center such as near centrally located.

[0024] In Fig. 1 the perimeter 14 is shown as being circular, but the apparatus is useful with any shaped perimeter such as rectangular, polygonal, oval and triangular.

[0025] The opening 16 is sized to fit an infant’s penis projecting through the opening 16. An infant’s penis is typically 0.5 inch in circumference. A preferred diameter for the opening is from about 1 to about 1.5 inch.

[0026] Although it is preferred that the opening 16 be circular, it can be in other shapes such as oval or triangular. When referring to the “diameter” of the opening 16 when it is not circular, reference is being made to the shortest distance across the opening. Thus, if an opening is oval in shape, then the term “diameter” refers to the small diameter of the oval. Stated in another way, the opening 16 in all versions needs to be sufficiently large that the infant’s penis can extend therethrough without difficulty.

[0027] The body 12 is formed from a material that is flexible and not irritating against a patient’s body, sufficiently resistant to penetration that a scalpel or needle pushed with a force of 10 Newtons, preferably 20 Newtons, and more preferably 50 Newtons, cannot penetrate the body, and sterilizable, such as by an autoclave. Stated another way, the body is not to be puncturable by a needle or scissors and scalpel when the medical professional uses a reasonable amount of force, which typically is at least 20 Newtons, and usually 50 Newtons, during the procedure so an accidental slip of blade or needle or scissors during a circumcision procedure does not occur. So there is no penetration by a force of 10 Newtons or less, preferably 20 Newtons or less, and more preferably no penetration by a force of 50 Newtons or less. Of course, the body can be designed that forces even higher than 50 Newtons do not result in penetration.

To determine if a material is suitable by testing with a scalpel, this can be determined by using a scalpel normally used by a surgeon, namely a number 10 scalpel according to ASTM F1790/F1790M-15 effective the date of filing of this application. To determine if a material is suitable with a needle typically used by a surgeon, that is determined with a 28 gauge needle according to ASTM F2878-19 effective the date of filing of this application. So, the forces stated above are determine with a number 10 scalpel and 28 gauge needle utilizing these ASTM tests. The material preferably satisfies these tests for both a needle and scalpel, but in some instances, depending on the medical procedure, the material needs to be satisfactory for just the needle or the scalpel.

[0028] Preferably the material is a mesh, and more particularly stainless-steel mesh such as a mesh available under the brand name Labalpha, particularly stainless steel 304, smooth finish, 100 mesh, aperture of about 0.14 millimeter, and a wire diameter of about 0.11 millimeter. This mesh resisted penetration by a force in excess of 130 Newtons.

[0029] Other materials that can be suitable include plastics such as plastic polymers including, polycarbonate, polypropylene, polyethylene, polyvinylchloride, acrylonitrile butadiene styrene, polystyrene, polyethylene terephthalate glycol, and polymethyl methacrylate. Preferably the material used is medical grade.

[0030] A suitable mesh is made of stainless steel 316 with a squared shaped apertures of 0. 14 mm per side and wire diameter of 0.112 mm, circular with a diameter of about 9 inches and a circular central aperture of about 1.5 inches in diameter. There are 100 mesh per inch, namely 100 vertical wires and 100 horizontal wires per square inch, with an open area (between wires) of about 30% and a weight of about 63 Kg per square meter. It is available from TSWN (Taiwan Special Wire Netting Co., Ltd. located in Taiwan) under part number 316 100x0.11x10”.

[0031] With reference to Fig. 2 an alternate version of an apparatus 20 according to the present invention is shown. The apparatus of Fig. 2 is an adaptation of the apparatus 10 of Fig. 1. The version of Fig. 2 is adapted for situations where the periphery 14 of the body of Fig. 1 is not sufficiently smooth to avoid injury or irritation to a patient during circumcision. Accordingly, a covering 22 can be provided on the periphery 14 of the body. Likewise, a covering 24 can be placed on the edge 26 on the central opening.

[0032] The dimensions that are given for the diameter of the opening 16 are based on inclusion of the covering so that in Fig. 2 the diameter is shown by double arrow 28. Likewise, the diameter of the apparatus of about 6 to about 10 inches includes the covering

22.

[0033] Either or both coverings 22 or 24 can be used. The coverings 22 and 24 are preferably formed of a durable material such as medical grade silicone, polyethylene, polyvinylchloride, polypropylene, or Kevlar. The coverings can be formed as separate pieces that are attached to the body such as by epoxy adhesive or crimping. Alternatively, the covering can be applied as a coating, such as a spray-on coating that hardens in place.

[0034] With reference to Fig. 3, circumcision is conducted as normal, but with the addition of the safety apparatus 10. As shown schematically in Fig. 3, an infant 32 is laid on his back and a sterile drape 34 is placed over the infant covering the abdominal area, including the femoral arteries. The apparatus 10 is placed over the drape proximate to the infant’s skin with the infant’s penis 36 projecting through the opening 16. Generally the apparatus is placed against the sterile drape. A conventional circumcision is then performed on the projected penis. Circumcision is typically performed by placing a clamp on the penis. Typical clamps used are the Gomco clamp, the Plastibell device, and the Mogen clamp. The clamp or ring is attached to the penis and then the medical professional clips off excess foreskin.

[0035] Although the apparatus and method are particularly useful with infants, they can be used on a male of any age. Also there may be applications for a female such as central line placement.
