Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical devices, and in particular, relates to a minimally invasive fixing device and a shrapnel assembly suitable for the correction of a concealed penis. BACKGROUND

[0002] A concealed penis is a common clinical urological and andrological disease. Patients have normal anatomical penis length and function, but due to excessive skin and subcutaneous fat layer, loose or defective support structure, most or all of the penis body is hidden in the abdominal subcutaneous tissue, scrotum or pubic fat pad, resulting in a phenomenon of shortening or even complete non-exposure of the penis in appearance. This condition not only affects the psychological health of patients, but also affects normal sexual function and urination function, especially in children and adolescents.

[0003] Current correction surgery methods for concealed penis mainly include penis root fascia fixation and penis body reconstruction. Among them, penis root fixation is the core step in the correction of concealed penis, and its basic principle is to anchor the fascia tissue at the root of the penis to the deep and solid anatomical structure (such as the prepubic fat, pubic periosteum), thereby establishing a stable tissue traction force to prevent the penis from being "swallowed" or retracted by the subcutaneous tissue again. Through this method, the penis body can be effectively pulled out and restored to normal appearance and function.

[0004] However, the existing penis root fascia fixation usually requires a circumcision incision of the penis foreskin and separation "out of the package" to the root of the penis, which requires a large range of skin peeling, and after exposing the deep fascia tissue, the traditional suture needle is used to complete the suture fixation of the skin at the root of the penis and the deep tissue. Although this traditional surgical method is effective, it also has the following significant shortcomings:

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

[0006] 2. High operation risk: The traditional suture needle or puncture needle cannot stably control the puncture depth and direction, and it is easy to pierce the non-target fascia layer during the operation process, and even may injure the important blood vessels, nerves and other deep tissues behind the pubic bone, which has certain surgical risks.

[0007] 3. Inaccurate positioning: The existing technology generally lacks a standardized puncture depth and position control device, and the puncture operation depends on the personal experience of the doctor, which may lead to unsatisfactory fascia fixation due to different puncture depths or position deviations, affecting the postoperative correction effect.

[0008] 4. Fixation instability: using simple suture anchoring method, fascia fixation effect is limited by suture tension and ligation strength, lack of additional structure to assist fixation, there is a risk of postoperative suture loosening or fixation displacement.

[0009] 5. Insufficient hemostasis control: during the puncture process, the inner cavity of the puncture needle may form a blood overflow channel, 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 micro-invasive fixation device and surgical method that is structurally reasonable, easy to operate, stable in fixation, and high in safety. In particular, for mild to moderate concealed penis patients who are not suitable for traditional open surgery, there is a greater need for a technical solution that can achieve fascia anchoring through minimally invasive puncture, to reduce surgical trauma, speed up postoperative recovery, and improve surgical safety and consistency. SUMMARY

[0011] Technical problems to be solved

[0012] To solve the problems in the related art, the present application provides a traditional general anesthesia concealed penis correction surgery, which realizes local anesthesia under the condition of super micro incision, rapid concealed penis correction, avoids the large surgical trauma and high cost of traditional general anesthesia surgery, significantly shortens the correction time, significantly reduces the surgical complications, and realizes a local anesthesia, super micro-invasive, rapid correction, more safe non-surgical method for concealed penis, especially for mild concealed penis patients.

[0013] Technical solutions

[0014] To solve the above technical problems, the present application discloses a micro-invasive fixation device suitable for concealed penis correction, which is a non-surgical correction device, comprising a puncture needle with an internal cavity, a shrapnel assembly implantable in the human body and a medical suture.

[0015] The shrapnel push rod for pushing the shrapnel assembly out of the puncture needle is arranged in the pipe body of the puncture needle.

[0016] The shrapnel assembly is arranged in the puncture tip of the puncture needle in a curved shape and automatically opens after being pushed out by the shrapnel push rod.

[0017] One end of the medical suture is fixedly connected with the shrapnel assembly, and the other end is threaded out along the length direction of the puncture needle through the pipe body end of the puncture needle.

[0018] Further, the shrapnel assembly is a sheet-shaped high-recovery elastic material, which includes an angle part and wing spread parts arranged on both sides of the angle part, and the wing spread parts are symmetrically arranged with the central axis of the angle part.

[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 application has the following advantages:

[0035] 1. The present application provides a minimally invasive fixation device suitable for correction of concealed penis, which has the advantages of compact structure, simple operation, strong anchoring stability, and efficient and safe suture guiding design. By bending the spring sheet assembly into the puncture tip of the puncture needle and pushing it out with the spring sheet push rod, the implantation and anchoring operation is completed in a single puncture path, significantly simplifying the traditional general anesthesia operation steps and shortening the operation time and complexity. After the spring sheet assembly is pushed out by the spring sheet push rod, it automatically expands by its own elastic restoring force without the need for additional manual expansion or adjustment, and can form a reliable and balanced anchoring effect at the fascia layer or pubic periosteum position, effectively resisting tissue retraction force and improving the continuity and stability of postoperative fixation effect. At the same time, one end of the medical suture is fixedly connected to the spring sheet assembly, and the other end is pulled out from the end of the tube body along the length direction of the puncture needle, forming an integrated path for puncture and suture guiding, avoiding the cumbersome steps of additional threading or auxiliary guiding in traditional surgery, reducing the risk of intraoperative infection and suture misplacement, and facilitating the surgeon to directly tighten the suture for fixation operation, improving the overall surgical efficiency and minimally invasive nature.

[0036] 2. The spring sheet assembly automatically expands to form an equilateral triangular stable structure, enhancing the fascia fixation effect: by designing a spring sheet assembly containing an angle part and a wing spread part, and combining the center hole and side hole to form an equilateral triangular layout, when the spring sheet push rod pushes it out of the puncture needle, the spring sheet assembly can automatically expand elastically. The equilateral triangular structure utilizes the high recovery characteristics of elastic materials (such as nickel-titanium alloy) to achieve reliable expansion, and the chamfer or protrusion on the edge of the wing spread part enhances the positioning effect, effectively improving the anchoring stability on the fascia layer or periosteum layer, thereby achieving a lasting outward traction fixation effect at the root of the penis.

[0037] 3. Precise and controllable puncture depth and fascia anchoring positioning: the present application sets an accurate scale on the outer wall of the puncture needle, and sets a distinguishing mark at the 3.5-4.5 cm segment, with a warning mark at 5 cm, combined with the short bevel round tip design of the puncture needle 1, making the puncture path and depth control highly accurate. This structural design ensures that the spring sheet assembly 3 can be accurately deployed at the pubic fat layer or pubic periosteum layer, effectively avoiding the risk of misentry into deep tissue, and improving the safety and repeatability of fascia layer anchoring.

[0044] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0045] Surgical background description: when the minimally invasive fixing device suitable for correction of a concealed penis is implemented, puncture should be preferentially performed at the suprapubic edge or the skin at the root of the penis, and the puncture path should avoid damaging important blood vessels, nerve tissues and the urethra as much as possible, and the puncture is preferably performed vertically or with a slight inclination angle from the epidermis to the pubic periosteum, to ensure safety and effectiveness.

[0046] Regarding the tissues of the penis, they include, in sequence, the epidermis, the subcutaneous fat layer, the superficial fascia layer, the deep fascia layer, the Buck fascia layer and the pubic periosteum.

[0047] When the correction surgery of a concealed penis is performed, the implantation of the spring sheet assembly 3 is mainly below the pubic fat or above the pubic periosteum, to ensure stability. The puncture depth is controlled in the interval of 3.5-4.5 cm, so that the pubic fat or the pubic periosteum can be touched and fixed, to avoid affecting the safety of the surgery due to excessive puncture depth.

[0048] Embodiment one

[0049] A minimally invasive fixing device suitable for correction of a concealed penis comprises a puncture needle 1 with an internal cavity, a spring sheet assembly 3 implantable in a human body, a medical suture 5 and a spring sheet push rod 2.

[0050] The spring sheet push rod 2 is arranged in the pipe body of the puncture needle 1, and the spring sheet push rod 2 can push the spring sheet assembly 3 out of the puncture needle 1. The spring sheet assembly 3 is arranged in the puncture tip 11 of the puncture needle 1 in a curved shape and is in a compressed state. After being pushed by the spring sheet push rod 2, the spring sheet assembly 3 automatically expands. One end of the medical suture 5 is fixedly connected to the spring sheet assembly 3, and the other end of the medical suture 5 is arranged along the length direction of the puncture needle 1 and is arranged to pass out of the pipe body of the puncture needle 1.

[0051] Embodiment 2

[0052] 1. The structure of the spring sheet assembly: as shown in Figure 1 Figure 5 The spring sheet assembly 3 includes the corner portion 31 and the wing portion 32. The wing portion 32 is arranged symmetrically with the central axis of the corner portion 31.

[0053] The corner portion 31 is provided with a central hole 310, and the wing portion 32 is provided with a side hole 320. The central hole 310 and the side hole 320 are used to connect the medical suture 5. When the spring sheet 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 fascia anchoring.

[0054] The spring sheet assembly 3 is in a long strip shape in a compressed state, and the corner portion 31 and the wing portion 32 are partially attached, so that they can be smoothly loaded into the puncture needle 1.

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

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

[0057] Preferably, to illustrate the specific shape of the spring sheet assembly 3 in this embodiment, the Figure 6 method can be referred to. As shown in Figure 6 a, the spring sheet is folded from a long strip. The specific folding method is to fold along the 6a dashed line, and then fold along the Figure 6 b dashed line. Figure 6 c is the folded state in the puncture needle 1. Among them, the 6a dashed line is the folding line of the inclined long strip; Figure 6 the b dashed line is the axisymmetric folding line.

[0058] 2. The structure of the puncture needle: a scale is provided on the outer end surface of the puncture needle 1 along the length direction. The 0 scale section is located at the puncture tip 11, and the 3.5-4.5 cm section is provided with a mark different from other scale sections, which is used to indicate the depth of the target fascia layer. The 5 cm section of the scale is provided with a warning mark to prompt the operator to avoid deep puncture.

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

[0060] Preferably, on the inner wall of the puncture tip 11, blocking blocks 110 for automatically sliding out the spring sheet assembly 3 are respectively arranged in front of both ends of the spring sheet assembly 3.

[0061] ​3. Spring-loaded push rod structure: such as Figures 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] In the clinical use of the product, the puncture needle upper limiting device or visual assistance (such as B-ultrasound) should be used to control the puncture depth in the range of 3.5-4.5 cm, and the safety and anchoring force are balanced best. And the spring sheet is deployed in the deep fascia, which can maximize the avoidance of touch, tenderness and sexual life interference. The scar tissue after operation further strengthens the fixation and forms "tissue self-healing fit".

[0071] Specifically, the puncture depth needs to be accurately controlled according to the external scale of the puncture needle 1: the 0 scale section of the puncture needle 1 is the starting point of the puncture tip, and the puncture depth is preferably controlled in the 3.5-4.5 cm interval. This area is provided with a special mark section, indicating that the target fascia layer has been reached, such as the prepubic fat layer or the pubic periosteum. A warning mark is marked at a depth of more than 5 cm, and further advancement should be avoided to prevent injury to deep structures.

[0072] The release position of the spring sheet assembly 3 should be located on the surface of the prepubic fat layer or the pubic periosteum, and be fully unfolded to form an equilateral triangular anchor structure with the wing spread part 32 and the folded corner part 31, so as to realize the stable fixation of the spring sheet assembly 3 to the fascia layer by tensioning the medical suture 5.

[0073] This fixation mode aims to ensure the continuity and stability of the outward traction force of the penile root, prevent concealed penile retraction, and at the same time, ensure minimally invasive and easy operation.

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

[0075] (1) Vertical puncture scheme from the superior pubic margin: suitable for minimally invasive fixation device for correction of concealed penis, including puncture needle 1, spring sheet push rod 2, spring sheet assembly 3 and medical suture 5. This scheme adopts a vertical downward puncture path from the middle part of the superior pubic margin:

[0076] Operation steps:

[0077] SA1. In the supine position of the patient, determine the puncture point at the middle line of the superior pubic margin.

[0078] SA2. Use the puncture needle 1 to penetrate vertically along the middle part of the superior pubic margin, and refer to the scale on the puncture needle 1, with the 0 scale section as the starting point, and the preferred penetration depth is 3.5-4.5 cm section.

[0079] SA3. When the puncture depth reaches the 3.5-4.5 cm section of the scale, it is judged that the needle tip has reached the surface of the pubic periosteum.

[0080] SA4. Push the spring sheet push rod 2 to completely push out the spring sheet assembly 3 from the puncture needle 1, so that it automatically unfolds to form an equilateral triangular anchor structure.

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

[0082] This scheme is simple in path and intuitive in operation angle, suitable for patients with shallow fascial layer, reduces the complexity of intraoperative operation, and facilitates postoperative recovery.

[0083] (2) Transverse puncture scheme from the root of the penis

[0084] This scheme adopts a horizontal puncture path from the lateral side of the root of the penis, combined with a puncture needle 1, a shell push rod 2, a shell assembly 3, and a medical suture 5:

[0085] The operation steps include:

[0086] SB1. Determine the puncture point on the lateral side of the root of the penis, 2-3 cm away from the midline of the penis.

[0087] SB2. Use the puncture needle 1 to penetrate in the horizontal direction, control the depth of the puncture needle 1, and reach the 3.5-4.5 cm section according to the scale.

[0088] SB3. When the puncture needle 1 reaches the fascial layer, push the shell push rod 2 to push out and fully expand the shell assembly 3.

[0089] SB4. After the shell assembly 3 is expanded, the wings 32 are distributed on both sides to form an equilateral triangle fixed state.

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

[0091] Features: Suitable for patients with thick body fat, bypassing part of the adipose tissue through a lateral path, avoiding interference caused by longitudinal operation, but the operation angle requirement is higher, and attention should be paid to avoid blood vessel injury.

[0092] (3) Inclined angle puncture scheme (about 30°-45°)

[0093] In some patients, in order to balance the operation space and fascial layer position, an inclined angle puncture method can be used:

[0094] Operation steps:

[0095] SC1. Determine the puncture point on the superior pubic margin or the root of the penis.

[0096] SC2. Use the puncture needle 1 to penetrate the skin layer at an angle of about 30°-45°, towards the pubic pre-fat layer or pubic periosteum.

[0097] SC3. Refer to the external scale of the puncture needle 1 to ensure that the puncture depth is 3.5-4.5 cm, avoiding exceeding the 5 cm warning section.

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

[0099] SC5. Pull the suture 5 to adjust the position of the expanded shell assembly 3, and ensure that it is attached to the fascia layer.

[0100] Features:

[0101] This scheme reduces the interference with the surface tissue under the premise of ensuring the fixing effect, and is suitable for patients who need minimally invasive cosmetic effect.

[0102] Summary:

After the shell assembly 3 is expanded, an equilateral triangle layout is adopted, the wing spread part 32 is attached to the fascia layer through the folded corner part 31, and the anchoring effect is ensured. The puncture path should be selected according to the patient's body type, fat layer thickness, and doctor's operation habit to achieve the purpose of safe, effective, and minimally invasive fixation.

[0104] After the suture 5 is pulled out from the end of the puncture needle 1, the doctor manually tightens the suture 5, and uses the tension of the suture 5 to connect and pull the skin surface and the fascia layer or periosteum layer, so as to increase the exposed length of the root of the penis and achieve the fixing effect.

[0105] Among them, the doctor applies appropriate tension to the medical suture 5 according to the operation needs and the patient's body characteristics, ensures that the shell assembly 3 is closely attached to the fascia layer, and realizes the expected traction effect. After the suture 5 is tightened, its end is fixed through conventional surgical ligation technology at the skin exit, and the subcutaneous knotting method is preferably used to hide the suture nodule under the skin, ensuring postoperative aesthetics and comfort. After the operation is completed, further local anesthesia circumcision can be performed according to whether the prepuce is still too long, to complete the entire concealed penis correction.
