Description

Technical Field

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

[0002] 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 the position of the foreskin to be cut, so as to facilitate the installation of the circumcision stapler relative to the glans penis and the foreskin, and accurately determine the position of the foreskin to be cut. However, when the existing external positioning fixator is used, it will cause excessive folding of the inner plate of the foreskin between the internal and external fixators, increasing the path, resulting in excessive retention of the inner plate, stubborn postoperative edema, and affecting the appearance. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an external positioning fixator for a circumcision stapler. By designing the structure of the external positioning fixator, while ensuring the cooperation with the internal positioning fixator to position the foreskin, the folding path of the inner plate of the foreskin is reduced, the inner plate of the foreskin is cut more thoroughly, and the postoperative edema is less.

[0004] The utility model adopts the following technical solutions: an external positioning fixator for a circumcision stapler, including an annular body. The annular body is opened or closed through an opening, and when closed, it encloses the outside of the internal positioning fixator to cooperate with the limit of the foreskin. The annular body includes an upper wall and a bottom wall arranged from top to bottom. The cross-sections of the upper wall and the bottom wall are L-shaped, so that the inner side of the annular body encloses a lower section with a smaller size and an upper section with a larger size.

[0005] As an improvement, the annular body is an integral ring, and it is opened or closed by deforming the opening.

[0006] As an improvement, the annular body has several arc segments, and the arc segments are connected through a hinge structure and the opening is opened or closed by rotating at the hinge structure.

[0007] As an improvement, a plurality of fixing points are distributed at intervals along the circumferential direction on the inner wall surface of the upper wall.

[0008] As an improvement, the height of the upper wall is less than or equal to 20 mm.

[0009] As an improvement, the height of the upper wall is greater than 5 mm.

[0010] As an improvement, a removable blocking piece is arranged at the upper end of the inner wall surface of the upper wall. The blocking piece temporarily limits the size of the upper end of the inner wall surface of the upper wall and restores the open state above the upper wall after being removed.

[0011] Advantages of the present utility model: Through the structural design of the annular body, the bottom wall can well form a structural limit for the inner positioning fixator at the lower part, the upper wall cooperates with the inner positioning fixator to engage and position the foreskin, and the upper part can directly insert the housing of the foreskin stapler for installation operation, reducing the folding path of the inner foreskin plate, more thorough resection of the inner foreskin plate, and less postoperative edema.

[0016] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0017] As Figure 1 、 2 、3, and 4 show, which are specific embodiments of the outer positioning fixator for assisting the foreskin stapler of the present utility model. This embodiment includes an annular body 1. The annular body 1 is opened or closed through an opening, and when closed, it encloses the outside of the inner positioning fixator to cooperate and limit the foreskin. The annular body 1 includes an upper wall 11 and a bottom wall 12 arranged from top to bottom. The cross-sections of the upper wall 11 and the bottom wall 12 are L-shaped, so that the inner side of the annular body 1 encloses a lower section with a smaller size and an upper section with a larger size.

[0018] When the utility model is in use, the whole inner positioning fixator is placed into the foreskin cavity, and the glans penis is sleeved until reaching the coronal sulcus. Then, the annular body 1 is used to hoop the inner and outer plates of the foreskin from the outside. Specifically, during implementation, the bottom wall 12 contacts the structure of the inner positioning fixator from the lower part upwards to find the position. The upper wall 11 of the bottom wall 12 cooperates with the inner positioning fixator to evenly distribute and clamp and limit the inner and outer plates of the foreskin. By flipping the foreskin, the position of the coronal sulcus can be clearly observed. 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 under direct vision. Then, the position of the outer plate that needs to be cut is adjusted, completing a good alignment of the inner and outer plates in a concentric circle pattern. After that, the locking structure on the outer positioning fixator is closed to complete the final locking and fixation. The cross-sections of the upper wall 11 and the bottom wall 12 are L-shaped, and the overall enclosed annular structure forms a structural block at the lower part to limit the inner positioning fixator, and the upper part is in an open state. The housing of the foreskin stapler can be directly inserted from the upper space, so as to complete the cutting and suturing of the foreskin on the premise of ensuring the accurate positioning position of the foreskin, and reduce the card position path of the inner plate of the foreskin, making the resection more thorough and ensuring the surgical quality.

[0019] As an improved specific implementation manner, the annular body 1 is an integral ring, and its opening is opened or closed through deformation.

[0020] This implementation manner is not shown in the drawings. In this implementation manner, the annular body 1 can be made of a deformable material. There is an opening in the overall ring. The opening is opened by expanding the overall ring to hoop the outside of the foreskin, and then the opening is locked by closing. It cooperates with the inner positioning fixator to position the foreskin. The integrally arranged structure can reduce parts and costs and reduce the assembly difficulty.

[0021] As an improved specific implementation manner, the annular body 1 has several arc segments, and the arc segments are connected by a hinge structure and the opening is opened or closed by rotating at the hinge structure.

[0022] As Figure 1 shown, it is the structure of the annular body 1 with two arcs. The two arcs are rotatably connected by a hinge structure, and the opening is opened or closed through the hinge structure, so as to better adjust the size of the opening; according to needs, a structure with multiple arcs can be further set, and the arcs are connected by a hinge structure. Compared with the structure with two arcs, the structure with multiple arcs can make it more convenient for single-handed assembly operation when the outer positioning fixator positions the inner positioning fixator from the outside.

[0023] As an improved specific implementation manner, a plurality of fixed points 2 are distributed at intervals along the circumferential direction on the inner wall surface of the upper wall 11.

[0024] As Figure 3As shown, several fixed points 2 are used to clamp and limit the local foreskin, which can avoid rotational displacement of the inner and outer plates of the foreskin and fix it more securely. In addition, since only the pressure is applied to the local points, after the annular body 1 is removed, the surrounding blood supply will quickly make up for the local compression and ischemia state, so as not to cause tissue necrosis, thereby achieving better limiting fixation without causing damage to the foreskin tissue.

[0025] As an improved specific implementation manner, the height of the upper wall 11 is less than or equal to 20 mm.

[0026] like Figure 2 As shown, the height of the upper wall 11 is designed to be less than or equal to 20 mm. The height limit design avoids blocking the field of vision and affecting the operation when the inner and outer plates of the foreskin are adjusted.

[0027] As an improved specific implementation manner, the height of the upper wall 11 is greater than 5 mm.

[0028] The minimum height of the upper wall 11 is further limited, and while ensuring the structural strength of the upper wall 11, it is ensured that when the upper wall 11 cooperates with the internal positioning fixture, it has an effective height structure to clamp and limit the position of the foreskin, and at the same time prevent the internal positioning fixture from sliding out of the upper wall 11 from above when adjusting the foreskin.

[0029] As an improved specific implementation, a removable blocking piece 3 is provided at the upper end of the inner wall surface of the upper wall 11, which temporarily limits the size of the upper end of the inner wall surface of the upper wall 11 and restores the upper open state of the upper wall 11 after removal.

[0030] like Figure 4 As shown, the blocking sheet 3 forms a temporary blocking structure in a circle, which is used to limit the inner positioning fixture upward to improve the convenience of positioning and debugging the inner positioning fixture, and prevent the inner positioning fixture from slipping out of the opening of the upper wall 11 of the outer positioning fixture during adjustment. After the adjustment and positioning of the foreskin is completed, the blocking sheet 3 can be removed to open the space above without affecting the insertion and installation of the foreskin stapler from above. The connection between the blocking sheet 3 and the inner wall surface of the upper wall 11 can be set as a dotted line or point structure that can be broken by force, a column or hole structure that can be plugged and pulled out by force, etc.; or the blocking sheet 3 can be a separate multi-segment type, arranged at intervals on the entire circumference and removed separately.

[0031] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
