Abstract
A retractable intraosseous access system configured to transition between an active state and one of a folded state or a retracted state. In the folded state, the access assembly can be pivoted relative to the driver to collapse the access assembly against a handle. In the retracted state, the access assembly is slidably received within a housing of the driver. Advantageously, the retractably intraosseous access system can provide an “all-in-one” design that does not require assembling separate components. Further the retractably intraosseous access system can provide a compact outer profile requiring reduced storage space.
Claims21
A foldable intraosseous access system for accessing a medullary cavity, comprising:
- a driver including a housing extending along a longitudinal axis, and a grip extending along a grip axis angled relative to the longitudinal axis, the housing including a drive train;
- a single access assembly pivotably coupled to the housing between a folded state and an active state, the single access assembly including a needle defining a lumen, the needle extending parallel to the longitudinal axis in the active state and at an angle to the longitudinal axis in the folded state, the single access assembly further including an obturator disposed within the lumen of the needle, the drive train configured to provide rotational motion to the single access assembly in the active state to drill the needle of the single access assembly through a bone cortex;
- and
- a cradle mechanism including a first cradle slidably engaged to a second cradle, the cradle mechanism configured to retain a cam between the first cradle and the second cradle in one or more resting states to maintain the access assembly in one of the folded state or the active state.
A foldable intraosseous access system for accessing a medullary cavity, comprising:
- a driver including a housing extending along a longitudinal axis, and a grip extending along a grip axis angled relative to the longitudinal axis, the housing including a drive train;
- and
- a single access assembly pivotably coupled to the housing between a folded state and an active state, the single access assembly including a needle defining a lumen, the needle extending parallel to the longitudinal axis in the active state and at an angle to the longitudinal axis in the folded state, the single access assembly further including an obturator disposed within the lumen of the needle, the drive train configured to provide rotational motion to the single access assembly in the active state to drill the needle of the single access assembly through a bone cortex;
- and
- a socket mechanism including a socket having a socket recess disposed on a distal surface, the socket recess configured to engage a surface of a cam to retain the cam in one or more resting states and to maintain the access assembly in one of the folded state or the active state.
A retractable intraosseous access system for accessing a medullary cavity, comprising:
- a driver including a housing extending along a longitudinal axis, and a grip extending along a grip axis angled relative to the longitudinal axis, the housing including a drive train;
- a single access assembly slidably engaged with the housing between a retracted state and an active state, the single access assembly including a needle defining a lumen, the needle extending parallel to the longitudinal axis in the active state, the needle disposed in the housing in the retracted state, the single access assembly further including an obturator disposed within the lumen of the needle, the drive train configured to provide rotational motion to the single access assembly in the active state to drill the needle of the single access assembly through a bone cortex.
A method of accessing a medullary cavity, comprising:
- providing an intraosseous access system including a housing extending along a longitudinal axis, and an access assembly coupled to the housing, the access assembly including a needle;
- pivoting the access assembly from a retracted state, where the needle extends at an angle relative to the longitudinal axis, to an active state, where the needle extends parallel to longitudinal axis;
- and
- activating a drive train to rotate the needle about the longitudinal axis.
A method of accessing a medullary cavity, comprising:
- providing an intraosseous access system including a housing extending along a longitudinal axis, and an access assembly slidably engaged with the housing, the access assembly including a needle;
- sliding the access assembly along the longitudinal axis from a retracted state, in which the needle is disposed within the housing, to an active state, in which the needle extends from a distal end of the housing;
- and
- activating a drive train to rotate the needle about the longitudinal axis.
