[0028] The utility model provides a circumcision suture device, which solves the problem of poor closure of U-pins in the existing solution, and makes the U-pins close more neatly, avoids the situation of skewed pin feet, and ensures the blood vessel closure effect.

[0029] See also Figures 1 to 3 A circumcision suture device according to an embodiment of the present invention includes a glans cover 1, a staple cartridge 2, a U staple top body 3 and a U staple 4, and also includes a connecting rod, a handle, a spring, a knob, etc., for example Figure 6 As shown, this type of circumcision suture device is a prior art, and the components not described in detail in this article can all use the existing solutions. One of the main improvements of the utility model is that the glans hood 1 is provided with a circle of nail anvil grooves 5 on the upper surface close to the outside, and each nail anvil groove 5 is in the shape of a strip, corresponding to a U nail 4, and the bottom surface of the groove near the two ends of the strip gradually increases in depth and gradually decreases in width from the two ends to the middle, and the narrowest part of the width of the bottom surface of the groove matches the width of the nail foot of the U nail 4 (slightly larger than the width of the nail foot); the longitudinal section profile of each nail anvil groove 5 is two connected half-teardrop shapes (such as Figure 3 As shown), and the connection is a half-teardrop-shaped wider end; the cross-sectional profile of each nail anvil groove 5 is two connected teardrop-shaped (as shown Figure 2As shown, it has a wide end and a narrow end with a smooth transition in between, and the narrower end is in the shape of a teardrop at the connection point. The present design adopts this type of anvil groove 5 shape, which can better play a guiding role. The two ends of the anvil groove 5 are relatively wide (not too wide), and its width can allow a certain position error of the nail feet of the U nail 4; as the U nail 4 is nailed in and deformed, the nail feet are restricted to a more ideal position, that is, the U nail is sutured vertically to avoid skewing, and the two nail feet are flush with each other and basically coincide with the projection of the nail beam of the U nail 4, so that the blood vessel can be accurately closed and the neatness of the suture line can be ensured. The end of the nail foot can be optionally bent in the direction of the nail beam to further suture, such as Figure 3 As shown, accordingly, the middle part of the nail anvil groove 5 has a protrusion to provide guidance for the bending of the end of the nail leg; the semi-teardrop-shaped curved surface formed avoids the situation where the nail leg needs to continue to bend and deform to a large extent immediately after contacting the nail anvil groove 5, which helps to provide a better U-nail guiding deformation effect.

[0030] The glans hood 1 is a bell-shaped hood, and a connecting rod 6 is connected to the outer side of the top end of the glans hood 1, for example, in an integral manner, and the other end of the connecting rod 6 has an external thread for threaded connection with a knob. A guide cylinder 7 is provided inside the circumcision suture device, and the guide cylinder 7 is, for example, fixedly arranged with the U-nail top body 3, or arranged on other components. In short, the guide cylinder 7 is located at the central axis position of the circumcision suture device, and the connecting rod 6 is matched and inserted into the guide cylinder 7, and the connecting rod 6 can move axially inside the guide cylinder 7. One or more radial ribs 8 are fixedly arranged on the outer side of the connecting rod 6, and the guide cylinder 7 has a guide groove plate 9 at one end close to the glans hood 1, and a guide groove matching one radial rib 8 is formed between the two guide groove plates 9. The radial ribs 8 and the guide grooves are one or more groups, preferably multiple groups evenly distributed circumferentially. As Figure 1 As shown, the radial length of the radial rib 8 (the height of the radial rib 8 protruding from the connecting rod 6) is preferably as large as possible, so as to provide more accurate circumferential positioning; the axial length of the radial rib 8 (or the distance between the radial rib 8 and the side of the glans hood 1 away from the glans hood 1) is preferably as large as possible, so that the radial rib 8 always slides in the guide groove during the whole process from assembly to circumcision suturing. In this way, the position correspondence between the nail anvil groove 5 (glans hood 1) and the U nail 4 (other parts outside the glans hood 1) can be further ensured to be accurate, and the suture position of the U nail 4 can be prevented from deviating from the expected / exceeding the allowable error due to shaking, force, etc. during use.

[0031] In a more preferred embodiment, please refer to Figure 1There are multiple radial ribs 8 evenly distributed in the circumferential direction, and a groove is formed between the radial ribs 8 and the glans hood 1 for tightening and fixing the end of the foreskin B. During the operation, the patient's glans is first placed in the glans hood 1, and the foreskin B is put outside the glans hood 1. Then the end of the foreskin B is fixed in place by tying wire Z or other means to avoid movement of the foreskin B before and during cutting, which may lead to unsatisfactory cutting lines and suture lines. This solution utilizes a larger radial rib 8 structure to form a groove for tying and positioning the foreskin B between the radial ribs 8 and the glans hood 1, so as to facilitate more stable tightening and avoid the foreskin from falling out of the tying position and the failure of tying and positioning during use. Figure 1 In the illustrated embodiment, the side of the radial rib 8 close to the glans hood 1 is a bevel, and the foreskin binding position is on the connecting rod 6 between the radial rib 8 and the glans hood 1, which is generally in a bobbin-shaped structure. It is conceivable that in other embodiments, the radial rib 8 can be optionally extended to the glans hood 1, and the groove of the foreskin binding position is the intersection of the outer side of the glans hood 1 and the radial rib 8, which can also be suitable for the case where the foreskin length is relatively short.

[0032] As a supplementary note, Figure 1 As shown, the outer side of the guide cylinder 7 may be provided with an annular plate extending therefrom, so as to vertically fix and connect the guide groove plate 9; or Figure 6 As shown, the outer side of the guide groove plate 9 is fixedly connected to the inner wall of the U nail top body 3.

[0033] See also Figure 4 In some preferred embodiments, the pins of adjacent U-nails 4 are connected by a strip-shaped elastic connecting gasket 10. The elastic connecting gasket 10 is, for example, a curved or bent strip, and is provided with holes for the U-nails 4 to penetrate at least near the two ends. The elastic connecting gasket 10 is made of an elastic and non-irritating material such as silicone. Accordingly, in addition to the structure for accommodating the U-nails 4, the nail magazine 2 also has a structure for accommodating the elastic connecting gasket 10, so that the elastic connecting gasket 10 can be ejected together with the U-nails 4. In this solution, the U-nails 4 are connected by the elastic connecting gasket 10, which helps to prevent the U-nails 4 from sinking into the foreskin and avoid the difficulty of subsequent nail removal; and this elastic connecting gasket 10, which is only located between the U-nails 4, can be elastically deformed with the expansion and contraction of the foreskin to avoid causing discomfort to the patient.

[0034] More preferably, the glans hood 1 is provided with a circle of continuous or discontinuous nail foot gaskets 11 at the position of the nail anvil groove 5. In the state after suturing, the nail foot gaskets 11 and the elastic connecting gaskets 10 are clamped on both sides of the foreskin. After suturing, the gaps between the U nails 4 will be clamped by two layers of gaskets, which is helpful for closing the blood vessels when the blood vessels are just in the gaps between the U nails 4, or it is easy to find such unclosed blood vessels and then perform artificial suturing. In addition, the nail foot gaskets 11 can also prevent the nail foot parts from directly contacting and sinking into the foreskin, making it difficult to remove the nails. For example Figure 5 The structure shown is a discontinuously arranged nail foot gasket 11. It should be noted that it is only a schematic diagram. The specific shape and size of the nail foot gasket 11 can be adjusted according to the specific situation. It is preferably in line with the shape of the nail anvil groove 5. The nail foot gasket 11 can also be preset with a hole for the U nail 4 to penetrate. In some other embodiments, the nail foot gasket 11 is a ring-shaped gasket.

[0035] See also Figure 1 Preferably, the U nail top body 3 has a U nail positioning groove 12 that contacts the nail beam of the U nail 4 in a matching manner, thereby better limiting the position of the U nail 4 and further ensuring that the U nail 4 can be nailed in ideally and vertically.

[0036] See also Figure 1 , Figure 2 Preferably, at least one air vent 13 is provided on the glans cover 1, which can play a role in ventilation and regulating air pressure during the process of placing the glans in and removing it from the glans cover 1, thereby improving the convenience of operation and comfort of use.

[0037] The glans cap 1 is provided with a circular knife groove 14 at the inner side of the nail anvil groove 5, and the U nail top body 3 is fixedly or detachably provided with a circular cutting knife 15 at the inner side, and the circular cutting knife 15 matches the circular knife groove 14. The circular cutting knife 15 is preferably detachably connected by, for example, plugging or snapping, so as to facilitate replacement. Figure 1 (Simple illustration only), before suturing, the outer side of the circumcision knife 15 fits with the nail magazine 2, the blade of the circumcision knife 15 is located on the outer side, and the end of the circumcision knife 15 does not exceed the end of the nail magazine 2. In other words, before firing, the circumcision knife 15 and the inner side of the nail magazine 2 are in smooth transition, and then in the process of pre-tightening by the knob at the rear end (relatively moving the glans hood 1 to the left), the smooth transition surface can flatten the foreskin B cut, further ensuring the neatness of the cutting line and the suture line. During the circumcision suturing, the U nail top body 3 will move relatively to the right, and the U nail 4 and the circumcision knife 15 will move accordingly; wherein the position relationship satisfies: when the U nail top body 3 moves to the extreme position, the U nail 4 completes the deformation and closure, and the end blade of the circumcision knife 15 is located in the annular knife groove 14, thereby ensuring that the circumcision is complete and thorough. Preferably, a soft circumcision knife pad is embedded in the annular knife groove 14 to further ensure the cutting effect.

[0038] In summary, the circumcision suture device of the present invention can better guide the U-nail, make the deformation of the U-nail more ideal and avoid skewing, so as to accurately close the blood vessels and ensure the neatness of the suture line, which is helpful to improve the success rate and effect of the circumcision operation.
