Technical Field

[0001] The utility model relates to a medical device, in particular to an internal positioning fixator for a circumcision stapler. Background Art

[0002] The existing foreskin fixing devices include an internal positioning fixator and an external positioning fixator. The internal positioning fixator and the external positioning fixator cooperate with each other to position and fix the position of the foreskin to be cut, and then a circumcision stapler is installed for cutting and suturing. However, the structural design of the existing internal positioning fixator is inconvenient for operation, and the control of the inner plate of the foreskin cutting is not ideal, often resulting in too much retention of the inner plate of the foreskin, obvious postoperative edema, and affecting the clinical use and surgical effect. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an internal positioning fixator for a circumcision stapler. By improving the structure of the internal positioning fixator, a relatively reasonable and accurate cutting position of the inner plate of the foreskin is limited after positioning, and the operation convenience and surgical quality are improved.

[0004] The utility model adopts the following technical solutions: An internal positioning fixator for a circumcision stapler includes an annular body. The inner side of the annular body is hollow for sleeving the glans penis, and the outer side is used to cooperate with the external positioning fixator to position the foreskin.

[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , 2 , 3, 4, and 5 are specific embodiments of the auxiliary internal positioning fixer of the foreskin stapler of the utility model, which includes an annular body 1. The inner side of the annular body 1 is hollow for sleeve-mounting the glans penis, and the outer side is used for positioning the foreskin in cooperation with the external positioning fixer. The height of the annular body 1 is less than or equal to 15 mm.

[0021] When the utility model is in use, the whole annular body 1 is placed into the foreskin cavity, and then sleeved onto the glans penis until reaching the coronal sulcus. Then, the outer positioning fixator is used to hoop the inner and outer plates of the foreskin from the outside. The inner and outer plates of the foreskin are evenly clamped and limited. By flipping the foreskin, the position of the coronal sulcus can be observed directly. Taking the coronal sulcus as a mark, the positions of the inner plate of the foreskin and the frenulum that need to be cut are accurately adjusted directly under visual inspection. Then, the position of the outer plate that needs to be cut is adjusted, so that the inner and outer plates are in good concentric alignment. After that, the locking structure on the outer positioning fixator is used to complete the final locking for fixation. The height of the annular body 1 is designed to be less than or equal to 15 mm. The limitation of its height can avoid the inner plate being too long and affecting the appearance.

[0022] As a specific improved embodiment, the height of the annular body 1 is less than or equal to 10 mm.

[0023] Furthermore, for the selection of reducing the height of the annular body 1, in some patients with micropenis, especially children, the height of the annular body 1 is limited to less than or equal to 10 mm, which can avoid the corresponding inner plate being too long and affecting the appearance.

[0024] As a specific improved embodiment, the height of the annular body 1 is greater than or equal to 1 mm.

[0025] The minimum height of the annular body 1 is further limited to ensure the structural strength of the annular body 1 and at the same time ensure that the annular body 1 can effectively clamp and limit the position of the foreskin when cooperating with the outer positioning fixator.

[0026] As a specific improved embodiment, a detachable operation handle 2 is further provided on the upper part of the annular body 1. The operation handle 2 has a connection point 3 connected to the upper part of the annular body 1, and when an external force is applied, it is separated from the annular body 1 at the connection point 3.

[0027] As Figure 2 shown, through the setting of the operation handle 2, it is convenient for the operator to hold the handle for operation, making the operation more convenient. After completing the required operation, the annular body 1 and the operation handle 2 can be separated by destroying the structure of the connection point 3, which will not affect the subsequent installation of the foreskin stapler. The connection point 3 can be a breakable dotted or point structure for applying force between the annular body 1 and the operation handle 2, a column and hole structure for applying force to insert and pull out, etc.

[0028] As a specific improved embodiment, the outer edge of the annular body 1 has an outer protruding surface 11 that cooperates with the outer positioning fixator.

[0029] As Figure 4 、 5 shown, in the above embodiments, by setting the outer protruding surface 11, a folded surface structure is formed. When cooperating with the outer positioning fixator, the foreskin is folded and clamped for limiting, thereby improving the fixing effect.

[0030] As a specific embodiment of the improvement, the outer edge of the annular body 1 has a concave surface 12 that cooperates with the outer positioning fixture.

[0031] As Figure 4 , 5 shown, in the above embodiment, by setting the concave surface 12, a folded surface structure is formed. When cooperating with the outer positioning fixture, a folded clamping limit is formed on the prepuce, thereby improving the fixing effect. As an optimization, the protruding surface 11 and the concave surface 12 can be continuously arranged in cooperation, thereby forming a multi-segment folded structure to improve the limiting and fixing effect on the prepuce.

[0032] As a specific embodiment of the improvement, the outer edge of the annular body 1 has a plurality of fixing protrusions 13 that are circumferentially spaced apart.

[0033] As Figure 1 shown, when in use, the plurality of spaced fixing protrusions 13 form a local clamping limit on the prepuce at the position in the entire circumferential direction, increasing the local pressure and fixing effect, effectively avoiding the rotation and displacement of the prepuce. And because it is only a local point pressure, after the outer positioning fixture is removed, the blood supply around will quickly compensate for its local clamping ischemia state, and will not cause tissue necrosis. Thus, on the basis of achieving better limiting and fixing, no damage is caused to the prepuce tissue.

[0034] As a specific embodiment of the improvement, a nail plate 14 is further provided on the upper part of the annular body 1. A circle of nail grooves 15 is provided on the nail plate 14. The inner side of the upper part of the annular body 1 extends upward to form a cover body 16. The lower part of the cover body 16 is open for accommodating the glans penis.

[0035] As Figure 5 shown, in this embodiment, the cover body 16 is formed by extending upward from the upper part of the annular body 1. The glans penis is accommodated through a closed bell-shaped structure. The prepuce is turned outwards beyond the annular body 1 and the cover body 16. The outer side of the annular body 1 is positioned with the prepuce by the outer positioning fixture. A circle of nail grooves 15 on the nail plate 14 is used to correspond to the annular knife and suture nails on the prepuce stapler, participating in the cutting and suturing of the prepuce. This embodiment integrally sets the positioning and cutting stapler structures, simplifying the operation process.

[0036] As a specific embodiment of the improvement, the lower part of the outer edge of the annular body 1 extends outwards to form an arc-shaped step 17 or has an L-shaped cross-section.

[0037] As Figure 1 , 2, as shown in FIGS. 3, the arc-shaped step 17 or the step structure extending outward in an L shape is used to cooperate with the outer positioning fixator to press the foreskin for limiting. The foreskin can be attached to the arc-shaped step 17 or the step structure by virtue of its flexibility, and wraps the arc-shaped step 17 or the step structure from bottom to top and outward. When the inner and outer positioning fixators are assembled, the platforms on the inner positioning fixator and the outer positioning fixator are in the same plane (as Figure 3 shown), so that when placing the foreskin stapler, the ineffective folding distance of the foreskin is reduced, making the foreskin cutting more accurate and the inner plate resection more thorough.

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
