Detailed Description

The following detailed description of specific embodiments of the invention refers to the accompanying drawings.

As shown in fig. 1, 2, 3, 4, 5, and 6, a hemostatic nail cartridge beneficial to limiting used in a prepuce cutting stapler according to an embodiment of the present invention includes an annular body 1, a circle of cartridge body 2 penetrating up and down for passing suturing nails is disposed on the annular body 1, a limiting step 5 is disposed on the periphery of the annular body 1, the annular body 1 on the upper portion of the limiting step 5 is an insertion section 6 for loading into the stapler, and the limiting step 5 is used for limiting by abutting against the end of the housing of the stapler.

When the hemostatic stapler is used, suturing nails are stored in the bin body 2, the hemostatic nail bin is installed at the lower end of the anastomat shell, the inserting section 6 is inserted into the anastomat shell, and the limiting step 5 is used for abutting against the end part of the anastomat shell; the operator supports the glans penis against the lower end of the nail supporting seat of the glans penis cover sample, the foreskin is turned upwards to wrap the nail supporting seat of the glans penis cover sample, a columnar connecting bridge at the upper part of the nail supporting seat of the glans penis cover sample penetrates through a positioning hole in the center of the anastomat and penetrates out from the upper end, and threads and a screw part at the top end of the connecting bridge are screwed tightly, so that the nail supporting seat of the glans penis cover sample and the nail bin are mutually close to clamp the fores. Pressing the operating handle, the nail ring that pushes away in the anastomat and annular cutting knife remove to propping nail seat direction, and a plurality of ejector pads on the nail ring that pushes away insert a plurality of storehouse bodies 2 on the hemostasis nail storehouse, and the ejector pad can promote the suturing nail in the storehouse body 2 to propping the nail seat propelling movement, and the suturing nail pierces through the foreskin tissue, and the contact is propped the nail groove on the nail seat and is bent the shaping. The setting of spacing step 5 on the annular body 1 is for the structure in the anastomat shell of original whole packing into, can effectively guarantee the good and reliable spacing of hemostasis nail storehouse, and knob nut closes the dynamics of soon in addition more big, and the foreskin is pressed tighter, and it is more firm that the sewing nail bending shaping is more firm, and blood vessel can be pressed the nail tighter by the card in the tissue, and hemostatic effect is better.

As a modified embodiment, one end of the bin body 2 is provided with a limit cavity 3 which is used for being matched with a hemostatic pressure plate.

As shown in figures 2, 3 and 4, when in use, the hemostatic pressing plate is stored at the position of the limiting cavity 3 and is driven to be pushed out together to be nailed on foreskin tissues when the suturing nail is pushed out. Due to the arrangement of the limiting steps 5, the rotary force of the knob nut can ensure that the structure of the suturing nail combined hemostasis pressing plate can maximize the clamping pressure and the compression force of the blood vessel in the foreskin, the compression area of the hemostasis pressing plate on the foreskin tissue is increased, and the hemostasis effect is improved. The structure among the prior art, because nail storehouse may be passed not hard up, can't guarantee to increase and set up similar hemostasis clamp plate after, sew up the nail and can also reliably form the card and press the blood vessel, also can reduce hemostasis clamp plate compression strength, influence hemostasis effect, increase the risk of bleeding.

As a modified embodiment, a pressing wide edge 4 is formed between the adjacent limiting cavities 3, and the size of the pressing wide edge 4 is larger than the diameter of the suturing nail.

As shown in fig. 2, 3 and 4, the hemostatic pressing plate adopts a structure matched with the limiting cavity 3, the edges at two sides of the hemostatic pressing plate correspondingly press the wide edge 4, and the blood vessel in the wrapper often runs in a tortuous manner to the circumcision edge, so that after the anastomat finishes the fixation of the hemostatic pressing plate, the blood vessel which is not fixed and closed between two suturing nails runs between the two hemostatic pressing plates in a tortuous manner, the smaller the gap between the two hemostatic pressing plates is, the larger the area covered by the hemostatic pressing plate is, and the higher the possibility that a certain section or multiple sections of the blood vessel which is missed and is pressed by the hemostatic pressing plate is. After the route of the foreskin edge small blood vessel is dissected and analyzed, a tester selects different sizes to test, the gaps among the hemostatic press plates are set to be several standard sizes of 1.2mm, 1.1mm, 1.0mm and the like, and the hemostatic press plates at least on one side can press a certain section of the foreskin blood vessel. And when the diameter is larger than 1.2mm, the possibility that the blood vessel needs to be obviously twisted to be pressed is high, the larger the gap between the two hemostatic pressing plates is, the higher the probability of pressure leakage is, and the higher the bleeding probability is. Therefore, the gap between the compression wide edge 4, namely the correspondingly assembled hemostatic press plate, can be set to be less than or equal to 1.2mm so as to achieve clinically acceptable hemostatic effect. As shown in fig. 5, compared with the prior art in which only suturing nails are used for suturing, the width range of the adjacent hemostatic pressing plates can perform compression hemostasis on one or more sections of blood vessels on the tortuous path of the blood vessel, thereby greatly increasing the blood flow blocking points and improving the hemostasis probability. Even in the case that the broken ends of the blood vessel between the staples are missed and opened, the blood will not bleed because a certain segment at the proximal end of the blood vessel is pressed by the hemostatic pressure plate. In addition, under the condition that the penis is erected, because the blood vessels are pressed more tightly by the hemostatic pressing plate and the erected cavernous body tissue of the penis, the retraction is prevented, and the postoperative hematoma is avoided.

As a modified embodiment, the distance between the adjacent pressing broad sides 4 is more than or equal to 0.2 mm. The foreskin under the hemostasis clamp plate is relatively more fixed, and the elasticity is relatively poor, and the skin elasticity that the penis is erect leans on the skin extensibility between the hemostasis clamp plate, and the skin tissue between the hemostasis clamp plate is more, and elasticity is better after the operation, and the painful edema of penis erection is less, but the risk of bleeding is higher, otherwise foreskin skin tissue between the hemostasis clamp plate is less, though the hemostatic effect is better, elasticity can descend after the operation, forms the card pressure to the glans penis after the operation easily, forms pain, edema or even narrow ring. Through clinical experiments, the spacing of more than or equal to 0.2mm is set to keep the good elasticity of the prepuce of the penis on the basis of achieving the good hemostatic effect, so that the adverse consequences are avoided.

As an improved specific implementation mode, the bin body 2 is positioned in the middle of the projection position of the limit cavity 3.

As shown in fig. 3 and 5, in this embodiment, the suturing nail is nailed in the middle of the hemostatic pressing plate, so that the two wings of the hemostatic pressing plate with the suturing nail as the center are uniformly stressed, the contact with the foreskin and the penis is more stable, the compression on the blood vessel is tighter, and the hemostatic effect is better.

As a modified embodiment, the bin body 2 is positioned at the inner side of the projection position of the limit cavity 3.

As shown in fig. 1 and 2, under this embodiment, the suturing nail is nailed at the inner side part of the hemostatic pressing plate, guarantee that the hemostatic pressing plate is inboard to carry out stable compression to the foreskin tissue, the hemostatic pressing plate is close to the nail frame part of the suturing nail of the outer side wing and can also rely on the cooperation of the penis cavernosum tissue of force conduction effect and erection by the structural strength, oppress the blood vessel running between the two wings, better hemostatic effect can also be played, because the nail frame part of the suturing nail of the inclined to the inner side is closer to the operation incision, cause the unbalance of the two wings atress of the hemostatic pressing plate, when the penis is erect, can use the suture nail frame as the lever, there is a thrust and prying effect to the outer side wing of the hemostatic pressing plate, make the suturing nail more easily cut from.

As an improved specific implementation mode, the number of the bin body 2 and the limiting cavities 3 is one-to-one, so that one suturing nail corresponds to one hemostatic pressing plate for suturing.

As shown in figures 2 and 3, the limiting cavities 3 which are in one-to-one correspondence are arranged to be matched with the bin body 2, and the penis has good extensibility due to the gaps between the whole circle of suturing nails and the hemostatic pressing plate when the penis is erected, so that the prepuce can keep good elasticity, a patient does not have the feeling of being clamped and pressed easily during erection, and the comfort is improved.

As an improved specific implementation mode, one limiting cavity 3 is arranged corresponding to a plurality of cabin bodies 2, and a plurality of suturing nails are nailed corresponding to one hemostasis pressing plate.

As shown in fig. 4, in order to provide the embodiment with two limiting cavities 3, more than two limiting cavities 3 which are uniformly arranged may be suitably provided as required; after adopting above-mentioned structure, the area of single hemostasis clamp plate has been increased, a plurality of suture nails are followed closely on same hemostasis clamp plate, the inner edge forms a long arc hemostasis clamp plate, the hemostasis by compression region between the outer plate in the foreskin has been increased, because the foreskin is more big than the dorsal part and the ventral side of blood vessel distribution at the penis, the postoperative probability of bleeding of this department is great, this embodiment is with long curved hemostasis clamp plate nail oppression in above-mentioned position, can guarantee to the furthest that the blood vessel is oppressed steadily, hemostatic effect has been improved. And the tissue between two or more hemostatic press plates keeps certain extensibility and elasticity when the penis is erect, so that the penis is not painful to be pressed. The embodiment has certain advantages in hemostasis for the cases that the blood vessels of the foreskin of the penis are large and many cases. In addition, when the suturing nail sequentially falls off from the foreskin, the hemostatic pressing plate which is separated and falls off firstly can generate the lever prying-like effect on the suturing nail which does not fall off, so that the falling off of the residual suturing nail is accelerated, and the nail-falling-off time is shortened.

As a modified embodiment, the limiting cavity 3 is in a quadrilateral or fan shape, and the side edges of the limiting cavity are integrally formed with the pressing wide edge 4.

As shown in fig. 2, 3 and 4, the regular shape of the quadrangle is selected to facilitate the processing and assembling of the limiting cavity 3 and the hemostatic pressure plate matched with the limiting cavity.

As a modified embodiment, the limiting cavity 3 is rounded from edge to edge.

As shown in fig. 2, 3 and 4, the rounded angle is convenient for processing the spacing cavity 3 and the hemostatic press plate adapted to the spacing cavity 3, and is beneficial to the mutual installation of the hemostatic press plate and the spacing cavity 3, and after the matched hemostatic press plate is correspondingly provided with the rounded angle, the complications such as the cutting injury of the foreskin tissue caused by the sharp angle and the pain, bleeding and infection caused by the sharp angle are avoided.

As a modified embodiment, all the bin bodies 2 and all the limiting cavities 3 are uniformly arranged on the annular body 1.

As shown in fig. 1, 2 and 3, the hemostatic press plates are uniformly arranged, that is, the distance between the hemostatic press plates is the same, so that the compression probability of the hemostatic press plates on the foreskin blood vessel with missed pins is ensured to be kept in a uniform and stable state. The arrangement of the whole circle of the limiting cavity is uniform, so that the time for falling of the hemostatic plates of all parts after the operation together with the suturing nail is equivalent, and the attractiveness of healing of the incision is also ensured.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
