Owing to adopting the version of gun body, have only to during operation be anchored to trigger just, easy to operate; Owing to the tubular body portion of gun body adopts the form of reducing, suturing nail is ejected cylinder and plays spacing effect, not only can simplify the structure in gun body, but also ensure that the stability of work; Due to being specifically designed and the coordinating of Horizontal limiting plate in gun body of trigger drive mechanism, making operation more laborsaving, it is more accurate that suturing nail ejects the displacement that cylinder moves, thus improve the success rate peritomized and sew up; Owing to slide block and hollow push rod adopt removable card dress form, facilitate the installation of parts.
Owing to being additionally arranged safety fastener, and safety fastener being designed, so that operating safer and convenient, having fully demonstrated the design concept of hommization.
Due to coordinating of strip locating slot and strip positioning convex, it is ensured that the anvil pocket in annular anvil is corresponding with suturing nail.
Due to anvil pocket, adopting the structure to recessed arcwall face, the nail tip of suturing nail can progressively be drawn in by inflection after touching the arcwall face of anvil pocket, thus improve the success rate of stitching; It addition, annular edge bearing is made up of PC material, after the foreskin on glans penis seat is carried out ring cutting by cylinder-shaped cutter, the blade of cylinder-shaped cutter contacts with annular edge bearing, without damaging blade.
Owing to improving property of adjusting knob is designed, when hands touches adjusting knob, not only good hand touch, but also facilitate adjustment.
Helping de-plate owing to being additionally arranged rivet nut, thus adding the contact area of nail beam and human body skin, thus effectively prevent the skin of the human body situation by nail beam parcel, contributing to coming off of rivet nut.
Owing to being outer expanding shape by two angular outer inclines of shaft-like nail, inwardly bending in the process of skin can be penetrated in anti-non-magnetic shim angle, and the cut formation the top of the horn in angle outside the end at two shaft-like nail angles, make one inclined-plane of formation outside the end at shaft-like nail angle, when shaft-like nail angle touches the arcuate groove on nail anvil, just having an inside thrust, so that extend out two shaft-like nails angularly interior bendings, this design substantially increases the success rate of suture operation.
Owing to all turnings being designed as the form of arc chord angle, in order to avoid hindering skin, make suturing nail more safe and reliable.
It addition, it is emphasized that nail beam and rivet nut help the size of de-plate, be the optimum data obtained through many experiments, if rivet nut helps de-board size too small, then can not play use, if excessive, then can affect sewing effect.
Owing to the other end of cylinder is provided with end cap, on described end cap and be centrally located the periphery of through hole and be evenly equipped with 4 fixing holes, described 4 fixing holes eject on 4 fixing posts in the necking end of cylinder in order to be fixed on described suturing nail, and said structure form makes the location and installation of cylinder-shaped cutter more accurate.
Owing to the inner side cutting edge angle of circular blade is 25 ��, the outside cutting edge angle of described circular blade is 15 ��, therefore has splendid ring cutting effect.
