Advanced optimize the technical program, the cylindricality welding block lower face of nail taking out apparatus in orthopaedics, around cross protrusion
It is evenly arranged with reinforcement protrusion.
The beneficial effects of the invention are as follows：
1, in the technical program, the power of the power for pulling up nail and rotation nail is separated and is applied in different location, nail lock
Determine mechanism to be used for lifting locking nail, with cylindricality welding block to catching the cruciform vent of nail, with supersonic welder by cylindricality welding block
It is welded and fixed with nail, then detaches locking of bone nails mechanism, device entirety is detached from nail, nail upper end is welded with cylindricality at this time
Block welding is integrated, and uses spanner or interior hexagonal that can take out nail in this way.The benefit of ultrasonic bonding is weld interval
Short, welding temperature is almost room temperature, and weld strength is bigger, easy to operate.
2, drive nut can be adsorbed onto on welding bars by magnetizing head, when can prevent locking of bone nails mechanism from locking nail
Transition core wire mechanism deviates from out of truncated cone-shaped set or guide pipe, easy to use.
3, protrusion is reinforced in setting around cross protrusion, when cross protrusion is inserted into the cruciform vent of nail, reinforces
Protrusion is contacted with the upper surface of nail, is conducive to increase welding surface area in this way, cross protrusion is welded simultaneously with protrusion is reinforced
Onto nail.

Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figs. 1-3, nail taking out apparatus in orthopaedics includes locking of bone nails mechanism 1, transition core wire mechanism 2, ultrasonic welding machine
Structure 3；Locking of bone nails mechanism 1 includes the guide pipe 5 for being located at underlying truncated cone-shaped and covering 4, being located above；Outside truncated cone-shaped set 4
Wall is evenly arranged with anti-skid chequer in a circumferential direction；The upper end of truncated cone-shaped set 4 and 5 screw-thread fit of guide pipe；The lower end of guide pipe 5
There are two symmetrically arranged elastic anchor ear halfbodies 7 for connection；The lower end of each elasticity anchor ear halfbody 7 is respectively and fixedly provided with arc card 8；Two
A arc card 8 is inside truncated cone-shaped set 4；The circular diameter and truncated cone-shaped that two arc cards 8 surround in its natural state
The caliber for covering 4 lower ends is equal；Transition core wire mechanism 2 is located inside guide pipe 5；Transition core wire mechanism 2 includes the column positioned at lower end
Shape welding block 9, the drive nut 10 positioned at upper end and the hexagonal double-ended bolt 11 that is connected between cylindricality welding block 9 and drive nut 10；
The lower end of cylindricality welding block 9 is provided with cross protrusion 12；The top surface of drive nut 10 is provided with interior hexagonal screw hole 13；Drive nut
10 side is evenly arranged with anti-skid chequer in a circumferential direction；The outer diameter of drive nut 10, hexagonal double-ended bolt 11 and cylindricality welding block 9
The respectively less than internal diameter of guide pipe 5；Ultrasonic welding institution 3 includes the holder 6 for being mounted on 5 both sides of guide pipe, installs on the frame 6
The supersonic welder 14 at end, the cleaning cotton-padded covering 15 between holder 6 and supersonic welder 14；The supersonic welder 14
16 lower end of welding bars passes through cleaning cotton-padded covering 15 to extend in guide pipe 5 top for arriving at drive nut 10；Supersonic welder 14
16 lower end of welding bars is fixed with magnetizing head 17；9 lower face of cylindricality welding block, is evenly arranged with reinforcement around cross protrusion 12
Protrusion 18.
In the present embodiment, central principle is that transition core wire mechanism 2 is welded on nail by supersonic welder 14, is made
Cylindricality welding block 9 is integrally welded with nail, thus lengthens nail, and adds hexagonal double-ended bolt 11 and interior hexagonal screw hole,
Either rotation or lifting is all more convenient.
Transition core wire mechanism 2 in operation, is put into, drive nut 10 by the present embodiment in the lower end of cylindrical shroud 4 first
It is adsorbed onto on 16 magnetizing head 17 of welding bars, then gripping device is whole, and truncated cone-shaped set 4 is sleeved on the part that nail is exposed
On, then rotary round table shape covers 4, and two elastic anchor ear halfbodies 7 are mutually drawn close at this time, by nail banding.Then start ultrasonic wave
Welding machine 14, welding bars 16 push transition core wire mechanism 2, since elastic anchor ear halfbody 7 has locked nail, so pushing transition weldering
