Beneficial effect of the present invention:
Owing to adopting the version of rifle body, only need during operation to be anchored to trigger just, easy to operate; Tubular body portion due to rifle body adopts the form of reducing, ejects cylinder and plays spacing effect, not only can simplify the structure in rifle body, but also ensure that the stability of work suturing nail; Due to the special design of trigger drive mechanism and coordinating of Horizontal limiting plate in rifle body, make operation more laborsaving, the displacement that suturing nail ejects cylinder movement is more accurate, thus improves the success rate peritomized and sew up; Removable clamp form because slide block and hollow push rod adopt, facilitate the installation of parts.
Owing to having set up safety fastener, and safety fastener is designed, thus make operation safer and convenient, fully demonstrated the design concept of hommization.
Due to coordinating of strip locating slot and strip positioning convex, guarantee that the nail anvil groove in annular anvil is corresponding with suturing nail.
Due to nail anvil groove, adopt the structure to recessed arcwall face, progressively can draw in by inflection after the nail tip of suturing nail touches the arcwall face of nail anvil groove, thus improve the success rate of stitching; In addition, annular edge bearing is made up of PC material, and after cylinder-shaped cutter carries out ring cutting to the foreskin on glans penis seat, the blade of cylinder-shaped cutter contacts with annular edge bearing, and can not damage blade.
Owing to carrying out improvement design to adjusting knob, when hands touches adjusting knob, not only good hand touch, but also facilitate adjustment.
Help de-plate owing to having set up rivet nut, thus add the contact area of nail beam and human body skin, thus the situation that nail beam wraps up by the skin that effectively prevent human body, contribute to coming off of rivet nut.
Owing to being outer expanding shape by two shaft-like nail angle outer inclines, inside 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 the angle outside the end at two shaft-like nail angles, make to form an inclined-plane outside the end at shaft-like nail angle, when shaft-like nail angle touches the arcuate groove on nail anvil, just have an inside thrust, thus make bending in two shaft-like nail angles extending out, this design substantially increases the success rate of suture operation.
Owing to all turnings to be all designed to the form of arc chord angle, in order to avoid hinder skin, make suturing nail more safe and reliable.
In addition, it is emphasized that nail beam and rivet nut help the size of de-plate, be through many experiments and the optimum data that obtains, if rivet nut helps de-board size too small, then can not play use, if excessive, then can affect sewing effect.
