Description

Technical Field

[0001] This invention belongs to the field of medical devices, and specifically relates to a minimally invasive fixation device and spring assembly suitable for the correction of concealed penis. Background Technology

[0002] Concealed penis, also known as buried penis or impaled penis, is a common urological condition in men. Although the patient has a anatomically normal penis length and function, due to excessively thick skin or subcutaneous fat, or loose or defective supporting structures, most or all of the penile shaft is hidden under the abdominal skin, in the scrotum, or in the pubic fat pad, resulting in a shortened or even completely concealed penis. This condition affects not only the patient's mental health but also normal sexual and urinary functions, and its incidence is particularly high in children and adolescents.

[0003] Current surgical methods for correcting concealed penis mainly include penile root fascia fixation and penile shaft reconstruction. Penile root fixation is the core step in concealed penis correction surgery. Its basic principle is to suture and anchor the fascia tissue at the base of the penis to deep, strong anatomical structures (such as prepubic fat and pubic periosteum), thereby establishing stable tissue traction and preventing the penis from being "swallowed" or retracted by subcutaneous tissue again. This method effectively pulls the penile shaft outward, restoring normal appearance and function.

[0004] However, current penile root fascia fixation surgery typically requires a circular incision in the foreskin, followed by dissection and "unsheathing" to the base of the penis. This necessitates extensive skin dissection to expose the deep fascia tissue before using traditional sutures to fix the skin and deep tissue at the base of the penis. While this traditional surgical method is effective, it also has the following significant drawbacks:

[0005] 1. Large trauma and slow recovery: Due to the need for large-area skin incision and extensive tissue dissection, the surgical wound is large, postoperative swelling is obvious, and the recovery period is long, which increases the cost of hospitalization and nursing care. It is especially unsuitable for mild to moderate patients or outpatient minimally invasive scenarios.

[0006] 2. High operational risk: Traditional suture needles or puncture needles cannot stably control the puncture depth and direction, and are prone to puncturing non-target fascia layers during the operation, and may even accidentally injure important blood vessels, nerves and other deep tissues behind the pubic bone, which poses certain surgical risks.

[0007] 3. Inaccurate positioning: Current technologies generally lack standardized puncture depth and position control devices. Puncture operation relies on the doctor's personal experience, which can easily lead to unsatisfactory fascia fixation effect due to inconsistent puncture depth or position deviation, affecting the postoperative correction effect.

[0008] 4. Unstable fixation: The fascia fixation effect is limited by the suture tension and ligation strength when using simple suture anchoring. The lack of additional structures to assist fixation poses a risk of suture loosening or fixation displacement after surgery.

[0009] 5. Inadequate hemostasis control: During the puncture, a blood extravasation channel may form inside the puncture needle, increasing the risk of intraoperative contamination, infection, and tissue bleeding, especially in areas with rich blood supply in the fascia layer.

[0010] Therefore, in the field of concealed penis correction, there is an urgent need for a minimally invasive fixation device and surgical method that is structurally sound, easy to operate, provides stable fixation, and is highly safe. Especially for patients with mild to moderate concealed penis who are unsuitable for traditional open surgery, a technical solution that can achieve fascial anchoring through minimally invasive puncture is needed to reduce surgical trauma, accelerate postoperative recovery, and improve surgical safety and consistency of results. Summary of the Invention

[0011] Technical problems to be solved

[0012] To address the problems in related technologies, this invention provides a method that can replace traditional general anesthesia for concealed penis correction surgery. It achieves rapid concealed penis correction under local anesthesia with an ultra-small incision, avoiding the large surgical trauma and high cost of traditional general anesthesia surgery, significantly shortening the correction time, and significantly reducing surgical complications. It realizes a safer non-surgical method for concealed penis, especially for patients with mild concealed penis, using local anesthesia, minimally invasive techniques, and rapid correction.

[0013] Technical solution

[0014] To solve the above-mentioned technical problems, the present invention discloses a minimally invasive fixation device suitable for the correction of concealed penis. It is a non-surgical correction device, including a hollow puncture needle, a spring assembly that can be implanted into the human body, and medical sutures.

[0015] The tube of the puncture needle is provided with a spring push rod that can push the spring assembly out of the puncture needle;

[0016] The spring assembly is curved and located inside the puncture tip of the puncture needle, and automatically opens after being pushed out by the spring push rod;

[0017] One end of the medical suture is fixedly connected to the spring assembly, and the other end passes through the end of the tube of the puncture needle along the length of the puncture needle.

[0018] Furthermore, the spring assembly is a sheet-like high-resilience elastic material, including a bend portion and wingspan portions disposed on both sides of the bend portion, the wingspan portions being arranged symmetrically about the central axis of the bend portion;

[0019] The bend in the corner is provided with a central hole for connecting the medical suture;

[0020] The compressed spring assembly is elongated, with the corner portion partially fitting the wingspan portion.

[0021] Furthermore, the wing section has a side hole at its end; when the spring assembly is deployed, the central hole and the left and right side holes form an equilateral triangle distribution; the medical sutures pass through the central hole and the left and right side holes one by one.

[0022] Furthermore, a scale is provided on the outer end face of the puncture needle along its length; the 0 mark of the scale is located at the tip of the puncture needle.

[0023] The 3.5–4.5 cm section of the scale has markings that distinguish it from other scale sections.

[0024] Furthermore, the 5cm section of the scale is equipped with a warning sign.

[0025] Furthermore, the puncture needle has a short-beveled round tip with a bevel length of 1–3 mm and a needle tip angle of 15–25°.

[0026] Furthermore, at the end of the puncture needle tube, along the length of the puncture needle tube, a spring-loaded push rod limiting groove is provided.

[0027] Furthermore, the direction closer to the end of the puncture needle is the starting end of the spring push rod limiting groove, and the direction closer to the tip of the puncture needle is the ending end of the spring push rod limiting groove.

[0028] In the circumferential direction of the puncture needle, a spring push rod fixing groove is provided on one side of the starting end of the spring push rod limiting slide groove.

[0029] Furthermore, a hemostatic washer is fixedly provided at the front end of the spring push rod, and the hemostatic washer is in contact with the inner wall of the puncture needle. The hemostatic washer is provided with a suture outlet, and the suture passes through a dedicated "Y"-shaped anti-backflow port.

[0030] The present invention also discloses a spring sheet assembly for the correction of concealed penis. The spring sheet assembly is a sheet-like high-resilience elastic material, including a folded portion and wings disposed on both sides of the folded portion. The wings are arranged symmetrically about the central axis of the folded portion.

[0031] The bend in the angled portion is provided with a central hole, and the end of the wing portion is provided with a side hole; when the spring assembly is deployed, the central hole and the left and right side holes form an equilateral triangle distribution.

[0032] The compressed spring assembly is elongated, with the corner portion partially fitting the wingspan portion.

[0033] Beneficial effects

[0034] The present invention has the following beneficial effects:

[0035] 1. The present invention provides a minimally invasive fixation device suitable for the correction of concealed penis, which has many technical advantages such as compact structure, simple operation, strong anchoring stability and efficient and safe suture guidance design. By bending and retracting the spring assembly into the tip of the puncture needle and then pushing it out using the spring pusher, implantation and anchoring can be completed through a single puncture path, significantly simplifying the traditional general anesthesia procedure and shortening the operation time and complexity. After being pushed out by the spring pusher, the spring assembly automatically opens due to its own elastic recovery force, without the need for additional manual unfolding or adjustment. It can form a reliable and balanced anchoring effect in the fascia layer or pubic periosteum, effectively resisting tissue retraction and improving the persistence and stability of postoperative fixation. At the same time, one end of the medical suture is fixedly connected to the spring assembly, and the other end passes through the end of the tube along the length of the puncture needle, forming a complete integrated puncture and suture guidance path. This avoids the cumbersome steps of separate suture threading or auxiliary guidance required in traditional surgery, reduces the risk of intraoperative infection and suture misalignment, and allows the doctor to directly tighten the suture for fixation, improving the overall surgical efficiency and minimal invasiveness.

[0036] 2. The spring assembly automatically deploys to form an equilateral triangle stable structure, enhancing fascial fixation: By designing a spring assembly including a folded section and wingspan, combined with an equilateral triangle layout formed by a central hole and side holes, the spring assembly can automatically and elastically deploy when the spring pusher pushes out the puncture needle. The equilateral triangle structure utilizes the high resilience of elastic materials (such as nickel-titanium alloy) to achieve reliable deployment, and the chamfered or protruding edges of the wingspan enhance the positioning effect, effectively improving the anchoring stability on the fascia or periosteum, thereby achieving a long-lasting outward traction fixation effect at the base of the penis.

[0037] 3. Precise and controllable puncture depth and fascial anchoring: This invention achieves highly precise control over the puncture path and depth by setting a precise scale on the outer wall of the puncture needle, with distinguishing markings in the 3.5–4.5 cm range and a warning marking at 5 cm. Combined with the short, beveled, rounded tip design of the puncture needle 1, this ensures highly precise control over the puncture path and depth. This structural design ensures that the spring assembly 3 can be accurately deployed in the prepubic fat layer or pubic periosteum, effectively avoiding the risks of accidentally penetrating too deep into tissues, and improving the safety and repeatability of fascial layer anchoring.

[0044] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0045] Surgical background: When implementing a minimally invasive fixation device suitable for concealed penis correction, the puncture should preferably be performed from the skin at the upper edge of the pubic bone or the base of the penis. The puncture path should avoid damaging important blood vessels, nerve tissues and the urethra as much as possible. It is preferable to perform the puncture vertically or at a slight angle from the epidermis towards the periosteum of the pubic bone to ensure safety and effectiveness.

[0046] The penile tissues, in order, include the epidermis, subcutaneous fat layer, superficial fascia layer, deep fascia layer, Buck's fascia layer, and pubic periosteum.

[0047] During concealed penis correction surgery, the spring assembly 3 is implanted primarily below the prepubic fat or above the pubic periosteum to ensure stability. The puncture depth is controlled within the range of 3.5–4.5 cm to reach and fix it to the prepubic fat or pubic periosteum, avoiding excessive puncture depth that could affect surgical safety.

[0048] Example 1

[0049] A minimally invasive fixation device suitable for the correction of concealed penis includes: a hollow puncture needle 1, an implantable spring assembly 3, a medical suture 5, and a spring push rod 2.

[0050] The puncture needle 1 has a spring pusher 2 inside its tube, which can push the spring assembly 3 out of the puncture needle 1. The spring assembly 3 is curved and located inside the puncture tip 11 of the puncture needle 1, in a compressed state. After being pushed by the spring pusher 2, the spring assembly 3 automatically opens. One end of the medical suture 5 is fixedly connected to the spring assembly 3, and the other end passes through the end of the tube of the puncture needle 1 along its length.

[0051] Example 2

[0052] 1. Spring assembly structure: such as Figure 1 – Figure 5 As shown, the spring assembly 3 includes a folded portion 31 and a wingspan portion 32. The wingspan portion 32 is located on both sides of the folded portion 31 and is arranged symmetrically about the central axis of the folded portion 31.

[0053] The bend of the angled portion 31 has a central hole 310, and the end of the wing portion 32 has a side hole 320. The central hole 310 and the side holes 320 are used to connect the medical suture 5. When the spring assembly 3 is unfolded, the central hole 310 and the left and right side holes 320 form an equilateral triangle to enhance the stability of the fascial anchoring.

[0054] The spring assembly 3 is elongated in the compressed state, with the corner portion 31 and the wingspan portion 32 partially fitting together, allowing it to be smoothly inserted into the puncture needle 1.

[0055] Preferably, the edges of the wingspan 32 are provided with smooth chamfers. More preferably, to enhance the positioning effect of the wingspan 32, protrusions can be added to the edges of the wingspan 32 to increase friction.

[0056] Preferably, the spring assembly 3 is a sheet-like high-resilience elastic material, such as a medical nickel-titanium alloy or stainless steel spring.

[0057] Preferably, to illustrate the specific shape of the spring assembly 3 in this embodiment, please refer to... Figure 6 Method. For example... Figure 6 As shown in a, this shrapnel is formed by folding a long strip. Specifically, it is folded along the dotted line 6a, and then along... Figure 6 b is formed by folding the dotted line. Figure 6 c represents the folded state of the puncture needle 1. The dashed line in 6a represents the fold line of a slanted strip. Figure 6 The dashed line b is an axially symmetric fold line.

[0058] 2. Puncture needle structure: A scale is provided on the outer end face of the puncture needle 1 along its length. The 0-degree mark is located at the puncture tip 11. The 3.5–4.5 cm section has markings that are different from other marks to indicate the depth of the target fascia layer. The 5 cm section of the scale has a warning mark to remind the operator to avoid excessive puncture.

[0059] Preferably, the puncture tip 11 of the puncture needle 1 is a short bevel round tip with a bevel length of 1–3 mm and a needle tip angle of 15–25°, which facilitates smooth puncture and reduces tissue damage.

[0060] Preferably, on the inner wall of the puncture tip 11, along the front of both ends of the spring assembly 3, there are blocking blocks 110 for the spring assembly 3 to slide out automatically.

[0061] 3. Spring-loaded push rod structure: such as Figure 2-4 As shown, a spring-loaded push rod limiting groove 12 is provided along the length of the end of the puncture needle 1 tube. The direction closer to the end of the puncture needle 1 is the starting end of the spring-loaded push rod limiting groove 12, and the direction closer to the tip of the puncture needle 1 is the ending end of the spring-loaded push rod limiting groove 12. In the circumferential direction of the puncture needle 1, a spring-loaded push rod fixing groove 121 is provided on one side of the starting end of the spring-loaded push rod limiting groove 12, which is used to position and fix the spring-loaded push rod 2 during use.

[0062] Preferably, the spring push rod fixing groove 121 and the spring push rod limiting slide groove 12 are separated by a partition 122, wherein the partition 122 is in point contact with the puncture needle 1. By simply rotating the spring push rod 2, the flange 22 of the spring push rod 2 can be twisted off the partition 122, causing the flange 22 to slide into the spring push rod limiting slide groove 12, thereby releasing the locking of the spring push rod 2. More preferably, the length of the limiting slide groove 12 is less than 2 cm.

[0063] More preferably, to enhance the grip of the puncture needle 1 and the spring push rod 2, a widened tail section 13 and a pressing end 23 may be provided at the tail sections of the puncture needle 1 and the spring push rod 2, respectively.

[0064] 4. Hemostatic structures: such as Figure 1 As shown, a hemostatic washer 21 is fixedly mounted at the front end of the spring push rod 2. The hemostatic washer 21 fits against the inner wall of the puncture needle 1, and a suture outlet is provided on the hemostatic washer 21. The suture outlet adopts a "Y"-shaped anti-backflow structure, which facilitates the passage of the suture 5 and effectively prevents blood from flowing back along the puncture needle 1.

[0065] This invention integrates the spring pusher and the puncture needle into a single pushing system with a limiting groove and a fixing groove structure. This allows the operator to safely and controllably release the spring assembly after reaching a preset depth, and the pushing stroke is controlled by the length of the limiting groove. Furthermore, a hemostatic washer is provided at the front end of the spring pusher, and an anti-backflow suture outlet design is incorporated, which effectively seals the puncture channel during operation, reducing the risk of intraoperative bleeding and infection, and achieving the requirements for minimally invasive and safe fixation procedures.

[0066] Example 3

[0067] In this embodiment, based on the design in Embodiment 1, the spring assembly 3 is a sheet-like high-recovery elastic material, which can be circular or elliptical, and is folded in a semi-circular or semi-elliptical shape at the puncture tip 11.

[0068] Preferably, the outer periphery of the spring assembly 3 has multiple smooth anchoring teeth or barbed protrusions.

[0069] Example 4

[0070] When using this product clinically, the puncture depth should be controlled within the range of 3.5–4.5 cm using an upper limit device for the puncture needle or visual assistance (such as ultrasound) to achieve the best balance between safety and anchoring force. Furthermore, the spring clips are deployed in the deep fascia, minimizing tactile discomfort, tenderness, and interference with sexual activity. Post-operatively, the scar tissue is further reinforced and fixed, forming a "tissue self-healing adherence."

[0071] Specifically, the puncture depth needs to be precisely controlled according to the external scale of the puncture needle 1: taking the 0 mark of the puncture needle 1 as the starting point of the puncture tip, the puncture depth is preferably controlled within the range of 3.5–4.5 cm. This area is marked with special markings to indicate that the target fascial layer, such as the prepubic fat layer or pubic periosteum, has been reached. A warning mark is indicated at depths exceeding 5 cm; further advancement should be avoided to prevent accidental damage to deeper structures.

[0072] The release position of the spring assembly 3 should be located on the surface of the prepubic fat layer or the periosteum of the pubic bone, and fully extended so that its wingspan 32 and the folded part 31 form an equilateral triangle anchoring structure. The spring assembly 3 can be stably fixed to the fascia layer by tightening the medical suture 5.

[0073] This fixation method aims to ensure the continuity and stability of the outward traction force at the base of the penis, preventing the retraction of the concealed penis, while also taking into account minimal invasiveness and ease of operation.

[0074] In conjunction with the above embodiments, this device can perform the following operations:

[0075] (1) Vertical puncture approach from the upper edge of the pubic bone: This is a minimally invasive fixation device suitable for the correction of concealed penis, including a puncture needle 1, a spring pusher 2, a spring assembly 3, and medical sutures 5. This approach uses a vertical downward puncture path from the midline of the upper edge of the pubic bone.

[0076] Operating steps:

[0077] SA1. With the patient in a supine position, determine the puncture point at the midline of the upper border of the pubis.

[0078] SA2. Insert the puncture needle 1 vertically along the midline of the upper edge of the pubic bone, referring to the scale on the puncture needle 1, starting from the 0 mark, with a preferred insertion depth of 3.5–4.5 cm.

[0079] SA3. When the puncture depth reaches the 3.5–4.5 cm mark on the scale, it is determined that the needle tip has reached the periosteum of the pubic bone.

[0080] SA4. Push the spring push rod 2 to fully push the spring assembly 3 out of the puncture needle 1, so that it automatically unfolds into an equilateral triangle anchoring structure.

[0081] SA5. Ensure that the medical suture 5 passes smoothly through the end of the puncture needle 1, and then withdraw the puncture needle 1 and the spring push rod 2.

[0082] This approach is simple and intuitive, making it suitable for patients with shallow fascia layers, reducing the complexity of intraoperative procedures and facilitating postoperative recovery.

[0083] (2) Transverse puncture procedure from the base of the penis

[0084] This procedure employs a horizontal puncture path from the side of the penile root, combined with puncture needle 1, spring push rod 2, spring assembly 3, and medical suture 5.

[0085] The following steps are included:

[0086] SB1. Locate the puncture point on the side of the base of the penis, 2–3 cm from the midline of the penis.

[0087] SB2. Insert the puncture needle 1 horizontally, controlling the depth of the puncture needle 1 according to the scale, aiming for a depth of 3.5–4.5 cm.

[0088] SB3. When the puncture needle 1 reaches the fascia layer, push the spring push rod 2 to push out the spring assembly 3 and fully unfold it.

[0089] After the SB4. spring assembly 3 is deployed, the wingspan 32 is distributed on the left and right sides, forming an equilateral triangle fixed state.

[0090] SB5. Adjust the tension of the medical suture 5, remove the puncture needle 1 and the spring push rod 2, and complete the anchoring.

[0091] Features: Suitable for patients with thicker body fat, it bypasses some adipose tissue through a lateral approach to avoid interference from longitudinal manipulation, but the operation angle requires a high degree of precision and care must be taken to avoid vascular damage.

[0092] (3) Inclined puncture technique (approximately 30°–45°)

[0093] In some patients, to balance the operating space and the location of the fascia layer, an inclined puncture method can be used:

[0094] Operating steps:

[0095] SC1. Determine the puncture point at the upper edge of the pubic bone or the base of the penis.

[0096] SC2. Use puncture needle 1 to insert into the skin layer at an angle of about 30°–45°, toward the prepubic fat layer or pubic periosteum.

[0097] SC3. Refer to the external scale of the puncture needle 1 to ensure the puncture depth is in the 3.5–4.5 cm range, and avoid exceeding the 5 cm warning range.

[0098] SC4. Push the spring push rod 2 to push out the spring assembly 3 and unfold it into an equilateral triangle structure.

[0099] SC5. Adjust the position of the unfolded spring assembly 3 by pulling with medical suture 5 to ensure that it fits the fascia layer.

[0100] Features:

[0101] This approach minimizes interference with surface tissues while ensuring effective fixation, making it suitable for patients seeking minimally invasive cosmetic results.

[0102] Summary and explanation:

[0103] All three implementation methods use the puncture needle 1, spring push rod 2, spring assembly 3, and medical suture 5 as core components. The puncture depth is preferably controlled within the range of 3.5–4.5 cm, and precise positioning is achieved using a scale. After unfolding, the spring assembly 3 adopts an equilateral triangular layout, with the wingspan 32 and the folded corner 31 adhering to the fascia layer to ensure anchoring effect. The selection of the puncture path should be comprehensively evaluated based on the patient's body type, fat layer thickness, and the doctor's operating habits to achieve a safe, effective, and minimally invasive fixation procedure.

[0104] After the suture 5 is pulled out from the end of the puncture needle 1, the doctor manually tightens the suture 5. The tension of the suture 5 is used to connect and pull the skin surface layer with the fascia layer or periosteum layer, thereby increasing the exposed length of the penile root and achieving a fixation effect.

[0105] During the procedure, the doctor applies appropriate tension to the medical suture 5 based on the surgical needs and the patient's body shape, ensuring that the elastic component 3 fits tightly against the fascia layer and achieves the desired traction effect. After the suture 5 is tightened, its end is fixed at the skin exit point using conventional surgical ligation techniques, preferably using a subcutaneous knot to hide the suture knot under the skin, ensuring postoperative aesthetics and comfort. After the procedure, depending on whether the foreskin is still too long, a circumcision under local anesthesia can be performed to complete the correction of the concealed penis.

[0106] The preferred embodiments of the invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
