Description

Lengthen screw-type metal bone needle

Technical field

This utility model relates to technical field of medical instruments, and particularly one lengthens screw-type metal bone needle.

Background technology

Existing metal bone needle is in the majority with the design of polished rod type, and the thread head of screw-type design is also shorter, and the elasticity completely by spicule self in art completes fixing.

Summary of the invention

The purpose of this utility model is the defect overcoming prior art existence, provides a kind of structure simple, easy to operate, provides larger hold, greatly strengthen the lengthening screw-type metal bone needle of fixed effect in fixing.

The technical scheme realizing this utility model object is: a kind of lengthening screw-type metal bone needle, has spicule body; Described spicule body head has screw thread; The needle point of described spicule body is Rhizoma Sparganii tip, and the nearly needle tip of spicule body has spherical fixture.

Described in technique scheme, spherical fixture has screw thread to needle point section.

After adopting technique scheme, this utility model has following positive effect:

(1) this utility model spicule head end increases threaded area, provides larger hold, greatly strengthen fixed effect in fixing.

(2) the nearly needle tip of spicule body of the present utility model has spherical fixture, can be more stable fix.
