Abstract
The invention discloses a kind of metal bone needle of orthopaedics, especially a kind of blunt nosed metal bone needle.The metal bone needle includes tail portion, bar portion and the threaded portion and head of integral structure, be structurally characterized in that the head be it is blunt nosed, threaded portion and head are equipped with cutting edge, and chip space is equipped at cutting edge, and bar portion is equipped with several spaced antiskid grooves.The present invention have the advantages that head be it is blunt nosed, soft tissue can be protected very well.
Description
Technical field
The present invention relates to a kind of metal bone needle of orthopaedics, especially a kind of blunt nosed metal bone needle.
Background technique
Metal bone needle part implantation human body in the reduction of the fracture carries out drawing or playing in bone surgery interior fixed work
With.The head of existing metal bone needle is tip, is easy to cause to damage to soft tissue when being inserted into bone and flesh, be unsuitable to apply to hard
Cortex bone or the region that fracture occurred in the past.
Summary of the invention
It is metal blunt nosed, that soft tissue can be protected very well technical problem to be solved by the invention is to provide a kind of head
Spicule.
Technical solution used by the present invention solves the above problems is: the metal bone needle includes the tail portion of integral structure, bar
Portion and threaded portion and head, be structurally characterized in that the head be it is blunt nosed, threaded portion and head are equipped with cutting edge, at cutting edge
Equipped with chip space, bar portion is equipped with several spaced antiskid grooves.
Screw thread on threaded portion of the present invention is single-screw screw thread, and the tooth bottom of screw thread is in arc line shaped.
Screw thread on threaded portion of the present invention is double helix screw thread, and the tooth bottom of screw thread is linear；And threaded portion is straight
Diameter is gradually reduced from bar portion toward cephalad direction.
A planar slot is provided on tail portion of the present invention.
Compared with the prior art, the present invention has the following beneficial effects: the head of the 1, metal bone needle be it is blunt nosed, when use
Soft tissue can be protected well, the region fractured was occurred suitable for hard cortex bone or in the past, and be can be used for pelvic
The fixation of position；2, the arc line shaped of Bottom of Thread designs on threaded portion, increases the contact area between spicule and bone, passes through reduction
Radial cortex tension and so that stress is had optimal distribution in bone, since stress distribution has, so reducing to bone skin
The danger of matter damage can effectively improve the fixed anchoring of spicule, make spicule be suitble to Preserving time in vivo and avoid generating pine
It is dynamic；3, the straight design of Bottom of Thread and double helix Design of Screw Thread on threaded portion, bone chip can be from the teeth of double helix screw thread
Bottom discharge, to improve the cutting power of screw thread.

Specific embodiment
Embodiment 1:
Referring to figures 1-3, the present embodiment includes tail portion 1, bar portion 2 and the threaded portion 3 and head 4 of integral structure.Head 4 is blunt
Head, threaded portion 3 and head 4 are equipped with cutting edge 5, are symmetrically opened at cutting edge 5 there are two chip space 8, bar portion 2 is equipped with several
Spaced antiskid groove 6 is provided with a planar slot 9 on tail portion 1.Screw thread on threaded portion 3 is single-screw screw thread, screw thread
Tooth bottom 7 is in arc line shaped.
The present embodiment is used for cortex bone, in use, first being drilled with bone drill, then installs fixed metal bone needle.Chip space 8 is used
Biggish heat dissipation area is provided in the bone chips for excluding to generate when the cutting of cutting edge 5 and for heat dissipation, antiskid groove 6 is for preventing
It is sliding.The arc line shaped design of Bottom of Thread 7, increases the contact area of spicule and bone on threaded portion 3, by reducing radial cortex
Tension and so that stress is had optimal distribution in bone, since stress distribution has, thus reduce to cortical bone damage
Danger can effectively improve the fixed anchoring of spicule.
Embodiment 2:
- Fig. 6 referring to fig. 4, the present embodiment include tail portion 1, bar portion 2 and the threaded portion 3 and head 4 of integral structure, and head 4 is blunt
Head, threaded portion 3 and head 4 are equipped with cutting edge 5, and bar portion 2 is equipped with several spaced antiskid grooves 6, opens on tail portion 1
There is a planar slot 9.Screw thread on threaded portion 3 is double helix screw thread, and the tooth bottom 7 of screw thread is linear；And the diameter of threaded portion 3
It is gradually reduced from bar portion 2 toward 4 direction of head.
The present embodiment is used for cancellous bone, and application method is identical as embodiment 1.Chip space 8 is for excluding the cutting of cutting edge 5
When the bone chips that generate and provide biggish heat dissipation area for heat dissipation, antiskid groove 6 is for anti-skidding.Thread on threaded portion 3
The straight design and double helix Design of Screw Thread at bottom 7, bone chip can be discharged from the tooth bottom 7 of double helix screw thread, to improve
The cutting power of screw thread.
