One end is connected through mounting hole with locating dowel；The spring nesting is arranged on slide-bar, between housing and the body of rod.
Relative to novel general surgery nail taking-out forcepses common in the art, the novel general surgery provided in the utility model
With core structure of the nail taking-out forcepses using built-in hold assembly, it is to avoid sharp hold assembly leakage, in operation to suffering from
The secondary injury that person causes；The fixation for passing through elastic shaft activity by using the movable design of elastic arm and housing, elastic arm
In the mounting groove of housing, in use, nail taking-out forcepses are directed at nail, housing is nested on nail, downslide sliding sleeve is sliding
Road will be moved by the conical head at the top of elastic arm to elastic arm bottom, so as to extrude the spring shaft of elastic arm, make four bullets
Property arm move inward simultaneously, the clamping limb of elastic arm bottom is arranged to stretching out inside taper sheath, by fixed clamp and four folders
Between gripping arm, nail can be extracted by rotating or moving up housing from knochenbruch；Gradually become by taper sheath and with length
The cooperation of the clamping limb of change, goes for the different nail of multiple diameter, with good versatility；By being provided with knife
The slide bar of head, can further take out, compared to the screw of exclusive use after housing is positioned to nail after beneficial to slide bar, nail is unscrewed
Cutter has accurate positioning, the good advantage of installation；By the way that cutter head and slide bar to be set to be detachably connected, it can change as needed
With different cutter heads, it is adaptable to different nails, versatility is improved.The novel general surgery of this new offer has with nail taking-out forcepses
Easy to use, accurate positioning, security is good, use the small advantage of painful.
