Description

Technical Field

[0001] This invention relates to the field of male reproductive external health care and correction medical devices, IPC classification number: A61F5 / 00, specifically a wearable physical pressure retraction foreskin retraction device, belonging to Class I passive urological surface care auxiliary medical devices. It is suitable for men with physiological phimosis, secondary phimosis, and obese men with perineal pubic fat accumulation, abdominal fat hypertrophy causing penile concealment, and passive foreskin bulging. This product is available in multiple specifications. The basic model has a central through-hole diameter of 40mm and a uniform standard height of 20mm for the central columnar protrusion. Mass-produced models are available to suit all age groups, including models for teenagers and adults, with progressively larger central through-hole diameters of 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm, to match users with different penile base outer diameters. Background Technology

[0002] Currently available and mass-produced external devices for foreskin retraction mostly adopt a standard circular closed-loop structure, resulting in severe structural homogenization and a lack of overall design. This leads to inherent industry deficiencies in fit and wearing stability. Considering clinical use and long-term home use, the specific pain points of existing technologies are as follows: 1. Conventional standard circular closed-loop retraction rings have poor force balance, and the ring fits only to the coronal sulcus of the penis. The force is distributed laterally when worn, and it is very easy to slip, deviate, or fall off during daily walking and limb activities. It cannot effectively limit and fix the foreskin and has extremely poor retraction stability. 2. There is no standard for the wall thickness of conventional anti-reverse rings on the market. The wall thickness varies, and long-term contact with the coronal sulcus causes continuous local compression of the soft tissue of the coronal sulcus, which can easily lead to poor local blood circulation and cause discomfort such as swelling of the glans penis, local tenderness, and subcutaneous hematoma. 3. Low-end mass-produced adhesive components are made of industrial-grade recycled silicone and plastic materials, which have poor biocompatibility. Staphylococcus aureus, fungi and other pathogenic bacteria on the skin surface are easy to grow at the contact points. Long-term contact with the groin and private skin can easily induce skin redness, itching and contact dermatitis. 4. Traditional foreskin rings mostly adopt a solid closed-loop silicone one-piece structure, while split products use hard buckles for splicing and assembly. The buckles have high hardness and sharp edges, which rub against the delicate skin of the private parts, causing a strong stinging and discomfort. The uneven gaps in the splicing assembly make it easy to hide smegma, sweat and dirt, which are difficult to clean and disinfect, resulting in extremely poor hygiene. 5. The most common clinical radical treatment is circumcision, which is an invasive procedure with multiple medical risks, including intraoperative wound bleeding, postoperative wound infection, severe pain during recovery, scar hyperplasia, poor postoperative appearance, and long healing period. At the same time, most users have a fear of surgery and psychological resistance, and are unwilling to accept invasive surgical intervention. 6. Existing compression products have a single aperture specification, which cannot be graded to adapt to the different sizes of adolescent small-diameter penises and adult large-diameter penises, resulting in poor universality and low fit. Summary of the Invention

[0003] 3.1 The technical problem to be solved by the present invention 1. To address the shortcomings of circumcision surgery, such as invasiveness, postoperative discomfort, user psychological resistance, and the inability to retain foreskin tissue as a backup material for skin grafting, a purely external, non-invasive wearable device is provided; 2. Overcomes the problems of traditional circular compression rings, such as single-point compression of the coronal sulcus, easy slippage, poor hygiene, and skin irritation caused by the material; 3. Suitable for people with thick perineal and pubic fat and penile concealment and bulging, solving the pain points of conventional retraction rings that lack perineal support points and cannot stably retract the foreskin; 4. Replaces manual retraction of the foreskin, enabling all-day, hands-free fixation and extending the duration of glans exposure; 5. Gently reduces the sensitivity of the glans mucosa through purely physical friction, avoiding the drug side effects of topical delay creams; 6. Provides a short-term trial transition device for users who are hesitant about surgery, effectively keeping the foreskin cavity ventilated and dry, and helping to reduce the frequency of recurrence of superficial balanitis. 3.2 Core Innovative Technical Solution of this Invention

Novelty Enhancement: Unlike the traditional single-ring limiting structure of the coronal sulcus, this invention consists of two independent components working together: a silicone retraction main body and a four-point adjustable traction strap assembly. The silicone main body adopts an original triangular shield-shaped biomimetic base and a central coaxial hollowed-out protrusion integrated structure. Relying on the large area of ​​soft tissue in the perineum for adhesion and force, and with the matching four-point symmetrical straps for multi-directional traction, the force is concentrated on the penile base, pubic fat layer, and superficial suspensory ligament of the penis, locking the foreskin from the root. This is an industry-unique root traction retraction mechanical structure.
