Description

Technical Field

[0001] This utility model belongs to the technical field of circumcision device structure design, and particularly relates to an inner and outer ring assembly of a circumcision device. Background Technology

[0002] The inner and outer ring components of the foreskin ligator primarily serve as the positioning and ligating structure during foreskin ligation surgery. They assist in positioning the ligation coil and utilize the inner ring in conjunction with the coil to complete the ligation. The specific steps are as follows: the foreskin structure is widened using surgical forceps or other positioning tools. Then, the inner and outer ring components are placed on the glans penis to insert the rings. Once in place, the foreskin is pulled to the cylindrical mounting part for fixation. Finally, the elastic coil is used to secure it to the outer ring, and the foreskin is removed using the outer ring for positioning, ensuring a smooth excision surface.

[0003] The current inner ring has a sleeve-type structure, which can meet the needs of most surgical scenarios. However, in actual operation, when the patient's foreskin is too short or the foreskin tension is poor, the space after expansion will be small, and the inner and outer ring structures cannot be smoothly aligned. If brute force is used, it will cause pain to the patient. If it cannot be properly aligned, it will affect the alignment of the inner and outer rings, resulting in an uneven incision or failure to be properly ligated. Utility Model Content

[0004] The purpose of this utility model is to provide an inner and outer ring assembly for a foreskin ligator that facilitates ring placement and solves the problem of difficulty and inconvenience in ring placement when the foreskin is too short.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A foreskin ligator inner and outer ring assembly includes an inner ring 1 and an outer ring 2;

[0007] The inner ring 1 includes a cylindrical mounting part 10, a spoon-shaped limiting part 11 located at the top of the cylindrical mounting part 10, an annular locking part 12 located at the top of the spoon-shaped limiting part 11, and two support plate surfaces 13 located at the top of the annular locking part 12.

[0008] The spoon-shaped limiting part 11 is formed by vertically cutting a cup-shaped rotating structure, and the cut-out portion accounts for 50% to 70% of the entire cup-shaped structure; the cut-out portion forms the pressure outlet 11a;

[0017] In a further improvement or preferred embodiment of the aforementioned foreskin bandage inner and outer ring components, the upper edge of the outer ring 2 is provided with a clearance slot 2a for avoiding the frenulum.

[0018] In a further improved or preferred embodiment of the aforementioned inner and outer ring components of the foreskin ligator, the outer ring 2 is an inwardly concave arc-shaped ring structure, the outer wall surface of the support plate 13 is an arc-shaped structure, and the arc radius of the outer wall surface of the support plate 13 is not less than the arc radius of the outer ring 2.

[0026] The present invention will be described in detail below with reference to specific embodiments.

[0027] This utility model relates to an inner and outer ring assembly of a foreskin ligation device, which is mainly used to deal with situations where the foreskin is short or has insufficient expandability, ensuring that the patient can successfully complete the ligation and positioning in such situations.

[0028] Compared to the traditional cylindrical direct-connection method, the inner and outer ring structure of this utility model adopts a spoon-shaped connection structure. During use, a single-sided insertion method can be used. First, one side of the inner and outer rings is inserted into the ligation area, and then the foreskin is pulled to cover the other side for connection. The spoon-shaped structure ensures smooth single-sided insertion and forms a pressure outlet to avoid friction damage to the glans penis during insertion. The pressure outlet also allows for direct confirmation of whether the insertion depth or state meets the surgical requirements. Furthermore, to address the issue of the foreskin being unable to be pulled to the cylindrical installation part 10 for positioning and clamping when the foreskin is too short, a ring-shaped locking part 12 has been added compared to the existing inner and outer ring structure to achieve locking and fixation in this situation.

[0029] like Figure 1 , Figure 2 As shown, the main components of the inner and outer ring assembly of the foreskin banding device of this utility model include an inner ring 1 and an outer ring 2.

[0030] The inner ring 1 includes a cylindrical mounting part 10, a spoon-shaped limiting part 11 located at the top of the cylindrical mounting part 10, an annular locking part 12 located at the top of the spoon-shaped limiting part 11, and two support plate surfaces 13 located at the top of the annular locking part 12.

[0031] The cylindrical mounting part 10 is mainly used to position and lock the foreskin pulled to this position in conjunction with a coil clamp or other fixing device under normal circumstances, so that the elastic coil can be wrapped around the outer ring 2. The outer ring 2 is located on the inner side of the foreskin. The spoon-shaped limiting part 11 is used for positioning and alignment, while protecting the penile tissue. The supporting plate 13 is used for positioning and supporting the outer ring 2, ensuring that the relative positions of the inner and outer rings remain stable during the operation.

[0032] To meet the needs of the aforementioned specific scenarios and achieve an advanced unilateral surgical procedure, the spoon-shaped limiting part 11 in this invention is formed by vertically cutting the current cup-shaped rotating structure, with the cutting and removing portion on its side accounting for 50% to 70% of the entire cup-shaped structure; the cutting portion forms a pressure outlet 11a; to ensure that during the unidirectional excision process, the tissue is directly exposed through the pressure outlet, preventing the pressure outlet from being generated by the squeezing friction of the inner wall of the limiting part on the opposite side of the existing structure.

[0033] To accommodate shorter foreskins, this invention includes an annular locking part 12. The outer wall of the annular locking part 12 has an annular locking groove 12a, which allows for locking of the foreskin using a rope or similar device. The upper and lower sidewalls of the annular locking groove 12a protrude to form a limiting ring 12b to prevent the rope from coming loose or the foreskin from slipping, thus ensuring the smooth and stable execution of the ligation procedure.

[0034] Two support plates 13 are symmetrically arranged on the top of the annular locking part 12 and extend upward; the support plates 13 are used to position and support the outer ring to ensure the relative positional relationship between the inner and outer rings, wherein the outer ring 2 is fitted on the two support plates 13.

[0035] The upper edge dimension of the spoon-shaped limiting part 11 matches the annular locking part 12, and the lower edge dimension matches the cylindrical mounting part 10.

[0036] To ensure a smooth fitting process and reduce irritation to the patient's tissues, in this embodiment, the inner surfaces of the support plate 13, the annular locking part 12, and the spoon-shaped limiting part 11 are formed into smooth arc-shaped curved surfaces.

[0037] Based on the actual application scenario, and by statistically analyzing the requirements of the corresponding process of the banding surgery, the preferred solution is that the height of the spoon-shaped limiting part 11 is preferably set to 4~12mm, and the inner diameter of the outer ring is 9~36mm.

[0038] Specifically, the following optimized configuration parameters can be adopted:

[0039] 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; and the larger the inner diameter of outer ring 2, the greater the height of the spoon-shaped limiting part 11 area;

[0040] As preferred parameters, the height of the spoon-shaped limiting part 11 area can be set to: 4.32mm, 7.15mm, 10.07mm, 12.86mm.

[0041] In particular, to facilitate tying and prevent the tying coil head from getting stuck, a clearance slot 2a is provided at the upper edge of the outer ring 2 to avoid the coil tie.

[0042] Specifically, for ease of use, the outer ring 2 is an inwardly concave arc-shaped ring structure, and the outer wall of the support plate 13 is an arc-shaped structure, and the arc radius of the outer wall of the support plate 13 is not less than the arc radius of the outer ring 2.

[0043] Its specific usage includes the following steps:

[0044] Step A: Place the outer ring 2 onto the support plate 13 to connect the inner and outer rings;

[0045] Step B: Use a clamping tool to expand the foreskin and push the inner and outer rings to connect with the tissue. When the foreskin is short, use a single-sided enlargement method. First, put one side of the foreskin on the inner and outer rings, and then operate on the other side until both sides are put on. Use a fixing device to fix the foreskin on the inner ring. Use the cylindrical mounting part 10 or the ring locking part 12.

[0046] Step C: After determining the location, use a ligation coil to complete the ligation, remove the inner ring, and perform other surgical procedures.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
