Problems solved by technology

[0002] The steel needle is one of the necessary medical devices in the orthopedic external fixator. At present, the traditional steel needle has a single structure and a smooth surface. During the use of the steel needle, it cannot form a good biological seal with the patient's percutaneous soft tissue, such as Inadequate care can easily cause the patient's skin to grow downward and form a pouch, thereby increasing the probability of needle loosening and needle tract infection, which not only affects the patient's treatment effect, but also affects the patient's recovery progress. In view of the above defects, the implementation It is Necessary to Innovate the Design of the Steel Pin Part of the Orthopedic External Fixator

Abstract

The invention discloses a steel needle of an orthopedic external fixator, which comprises a bone nail, an elliptical column, a groove, an air cushion, a connecting column, an air bag, a pressing bar, a waist-shaped hole, and a rotating bar. The orthopedic external fixator steel needle has ingenious structure, powerful function, and simple operation. By using this device, the percutaneous soft tissue part of the patient can grow into the groove in the future, preventing the skin from growing downward to form a pocket, thereby effectively reducing The probability of steel needle loosening and needle tract infection not only ensures the treatment effect of the patient, but also ensures the progress of the patient's recovery.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a steel needle of an orthopedic external fixator. Background technique [0002] The steel needle is one of the necessary medical devices in the orthopedic external fixator. At present, the traditional steel needle has a single structure and a smooth surface. During the use of the steel needle, it cannot form a good biological seal with the patient's percutaneous soft tissue, such as Inadequate care can easily cause the patient's skin to grow downward and form a pouch, thereby increasing the probability of needle loosening and needle tract infection, which not only affects the patient's treatment effect, but also affects the patient's recovery progress. In view of the above defects, the implementation It is necessary to innovate the design of the steel needle part of the orthopedic external fixator. Contents of the invention [0003] The technical problem to be solved by the ...
