Area of Science:

Medical Devices
Hematology
Surgical Instruments

Background:

Traditional bone marrow aspiration needles, such as Salah and Klima, have design limitations.
These 1930s-era needles lack ergonomic features, hindering operator grip and maneuverability during sternal puncture.

Purpose of the Study:

To design and evaluate a novel sternal aspiration needle that overcomes the limitations of existing instruments.
To enhance operator comfort, grip, and control during bone marrow aspiration procedures.

Main Methods:

A new sternal aspiration needle was designed with a larger profile and improved handle features.
The design incorporates a domed stilette handle for operator comfort and a large T-bar handle for enhanced grip and control.

Main Results:

The redesigned needle offers a larger size for a better fit in the operator's hand.
Improved maneuverability and precise control during sternal puncture are achieved through the ergonomic handle design.

Conclusions:

The newly designed sternal aspiration needle effectively addresses the ergonomic and functional shortcomings of older models.
This improved instrument enhances the safety and efficiency of bone marrow aspiration procedures.
