The screw thread that hollow bore sighting device one end is equipped with is straight screw thread.
It is described limit sheath be weldingly fixed on hollow bore sighting device be equipped with screw thread one end, this avoid single-piece at
Product screw thread and step surface back chipping are incomplete, and being directed at it and limiting sheath end face can not achieve face face with surface of steel plate and come into full contact with.
The clear size of opening of the hollow bore sighting device is Φ 2.4mm- Φ 2.8mm, can establish screw way for 2.7mm drill bit
Guiding role is provided.
The straight screw thread is the nonstandard screw thread that outer diameter is Φ 5.3mm, can realize screw thread locking with cooperating with bone plate
Purpose, avoid loosening when bending.
The limit sheath end face is all plane, it is therefore an objective to allow itself and surface of steel plate to realize that face face comes into full contact with, hold it
By most of load, avoid causing with bone plate screw thread stress with bone plate deformed threads.
The anti-skid chequer of the hollow bore sighting device is straight knurling, and the pitch of straight knurling is 0.6 mm.
To avoid bending machine and steel plate from being engaged tension, the spanner preformed hole perpendicular to through-bore axis, the spanner is pre-
Boxing out is Φ 4.5mm straight hole.
The spanner preformed hole is perpendicular to the Φ 4.5mm straight hole of through-bore axis.
The beneficial effect of the utility model hollow bore sighting device is: provided by the utility model is a kind of orthopaedics with bone plate
Bending machine, primarily directed to the steel-plate bending machine with bone plate.Wherein screw thread is the nonstandard screw thread of Φ 5.3mm, can with bone plate
Screw thread effectively locks;Limit sheath end face can come into full contact with with plate surface, carry most of load, avoid screw thread directly by
Power leads to that locking effect is not achieved with bone plate thread failure;It is impaired that surface of steel plate is avoided simultaneously, ensure that the accurate of steel plate
Bending.With the hollow design of bone plate bending machine, the function that the instrument is aimed at as bit bore is realized, has been reached multi-functional
Property.
