Description

Technical Field

[0002] The inner and outer ring components of the circumcision device are primarily used as positioning mechanisms during circumcision surgery, assisting in the positioning of the circumcision coil. The inner ring, in conjunction with the circumcision coil, completes the circumcision. The specific steps involved using surgical forceps and other positioning tools to stretch the foreskin, then placing the inner and outer ring components over the glans penis. Once in place, the foreskin is pulled to the cylindrical mounting portion for securement. Finally, the elastic coil is placed over the outer ring, and the outer ring is used to position the foreskin for resection, ensuring a smooth end surface.

[0003] The current inner ring is a sleeve-type structure, which can meet the needs of most of the above-mentioned surgical scenarios.

[0031] The present invention is described in detail below with reference to specific embodiments.

[0032] The present invention relates to an inner and outer ring assembly of a foreskin ligation device, which is mainly used to deal with the situation where some foreskins are short or have insufficient expansibility, ensuring that patients can successfully complete ligation docking and positioning in this situation.

[0033] Compared to the traditional cylindrical straight-on docking method, the inner and outer ring structures of the present invention adopt a spoon-shaped docking structure. During use, a unilateral incision method can be adopted, first inserting one side of the inner and outer ring into the ligation area, and then pulling the foreskin to cover and achieve the other side of the incision. The spoon-shaped structure ensures smooth unilateral incision and forms a pressure outlet to prevent friction damage to the glans penis during the incision process. The pressure outlet can also be used to visually confirm whether the incision depth or state meets the surgical requirements. At the same time, to solve the problem that the foreskin cannot be pulled to the cylindrical mounting portion 10 for positioning and clamping when the foreskin is too short, an annular locking portion 12 is newly added compared to the existing inner and outer ring structure to achieve locking and fixation in this situation.

[0034] like Figure 1 、 Figure 2 As shown, the main components of the inner and outer ring components of the foreskin ligation device of the present invention include an inner ring 1 and an outer ring 2;

[0035] The inner ring 1 includes a cylindrical mounting portion 10, a spoon-shaped limiting portion 11 located at the top of the cylindrical mounting portion 10, an annular locking portion 12 located at the top of the spoon-shaped limiting portion 11, and two supporting plate surfaces 13 located at the top of the annular locking portion 12;

[0036] The cylindrical mounting portion 10 is mainly used to cooperate with a fixing device such as a coil clamp to position and lock the foreskin pulled to this position under normal circumstances, so as to facilitate the elastic coil to be wrapped around the outer ring 2. The outer ring 2 is located on the inner side of the foreskin. The spoon-shaped limiting portion 11 is used for positioning and alignment while protecting the penile tissue. The support plate surface 13 is used to position and support the outer ring 2 to ensure that the relative positions of the inner and outer rings remain stable during the operation.

[0037] In order to meet the needs of the aforementioned specific scenarios and to realize a unilateral advanced surgical operation method, the spoon-shaped limiting portion 11 in the present invention is formed by vertically cutting the current cup-shaped rotating structure, and the cut-out portion on its side accounts for 50% to 70% of the entire cup-shaped structure; the cut portion forms a pressure outlet 11a; to ensure that during the unidirectional enucleation process, the tissue is directly exposed through the pressure outlet, preventing the existing structure from being squeezed and rubbed on the tissue by the inner wall of the limiting portion on the opposite side. The traditional structure does not have a pressure outlet.

[0038] At the same time, in order to meet the fixation requirements of a shorter foreskin, an annular locking portion 12 is provided in the present invention. The outer wall of the annular locking portion 12 is provided with an annular locking groove 12a so that the foreskin can be locked by using a device such as a tying rope. The upper and lower side walls of the annular locking groove 12a are protruding in phase to form a limiting ring 12b to prevent the tying rope from loosening or the foreskin from sliding, thereby ensuring the smooth and stable progress of the ligation operation.

[0039] Two support plate surfaces 13 are symmetrically arranged on the top of the annular locking portion 12 and extend upward; the support plate surfaces 13 are used to position and support the outer ring to ensure the relative position relationship between the inner and outer rings, wherein the outer ring 2 is sleeved on the two support plate surfaces 13.

[0040] The upper edge size of the spoon-shaped limiting portion 11 matches the annular locking portion 12 , and the lower edge size matches the cylindrical mounting portion 10 .

[0041] In order to ensure a smooth wearing process and reduce stimulation to the patient's tissue, in this embodiment, the inner surfaces of the support plate surface 13, the annular locking portion 12, and the spoon-shaped limiting portion 11 form smooth arc-shaped surfaces.

[0042] According to the actual application scenario and the statistical requirements of the corresponding process of the ligation surgery, as the preferred solution, the height of the spoon-shaped limiter 11 is preferably set to 4-12mm, and the inner diameter of the outer ring is 9-40mm. Specifically, the following optimized configuration parameters can be adopted:

[0043] Inner diameter of outer ring 2: 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 37mm, 38mm, 39mm, 40mm; and the larger the inner diameter of outer ring 2, the greater the height of the spoon-shaped limit portion 11;

[0044] As a preferred parameter, the height of the spoon-shaped limiting portion 11 area can be set to: 4.32mm, 7.15mm, 10.07mm, 12.86mm.

[0045] In particular, in order to facilitate the tying and avoid the tying coil head from getting stuck, an air-avoiding notch 2a for avoiding the coil lacing is provided at the upper edge of the outer ring 2 .

[0046] In particular, to prevent the inner ring from adhering to the foreskin tissue during later removal and to reduce the patient's pain, the inner ring is made of POM (polyoxymethylene resin);

[0047] In particular, for ease of use, the outer ring 2 is an inwardly concave arc-shaped ring structure, the outer wall of the support plate surface 13 is an arc-shaped structure, and the arc radius of the outer wall of the support plate surface 13 is not less than the arc radius of the outer ring 2.

[0048] Its specific use includes the following steps:

[0049] Step A: Put the outer ring 2 on the support plate surface 13 to connect the inner and outer rings;

[0050] Step B: Use a clamping tool to expand the foreskin and push the inner and outer rings to connect with the tissue. If the foreskin is short, use a unilateral incision method to first put one side of the foreskin on the inner and outer rings, then operate the other side until both sides are put on. Use a fixing device to fix the foreskin to the cylindrical mounting portion 10 or the annular locking portion 12 on the inner ring;

[0051] Step C: After the position is determined, use the ligation coil to complete the ligation, withdraw the inner ring, and perform other surgical operations.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
