Integral type bone cement filling apparatuss with stirring and perfusion functional
Technical field
The present invention relates to medical instruments field and in particular to stirring and perfusion functional integral type bone cement filling apparatuss.
Background technology
It is often necessary to be irrigated to patient after by bone cement stirring in bone surgery, and the stirring of bone cement and filling
Note process is more complicated, needs doctor that the characteristic of bone cement is known, and can seize the opportunity exactly in operation, but due to
The self property of bone cement is determined, operating process only has short a few minutes, and stirring and perfusion link are all comparatively short, easily
The uneven situation of stirring occurs.
Additionally, whole operation process is in a hurry, the skill of doctor and degree of concentrating are required very high, and surgery situation
Again complicated and changeable, careless slightly may hold the bad best opportunity, bone cement have to be re-modulated, this adds increased patient's
Misery, and doctor also needs to experience once above-mentioned operating process again, and work load is well imagined;And re-modulate bone water
Mud also result in the waste of material.
Existing bone cement stirring mode is divided into two kinds, and one kind is manually to be stirred, and is held at one by artificial
Carried out with stirring rod in device, easily appearance stirring is uneven, and viscosity is not easily controlled, and affects stirring efficiency.Another
It is to need to coordinate motor to be stirred, need motor and the control chamber to motor control, and the vacuum equipment of evacuation, its knot
Structure is complicated, is not easy to use in operative site.
Content of the invention
Invention purpose be solve disadvantages described above, a kind of integral type bone cement filling apparatuss are provided, its be provided simultaneously with stirring and
