Abstract
A collar for a surgical access device includes an annular body laterally attachable to a cannula of the surgical access device. A spring is coupled to the annular body and movable between an uncompressed state and a compressed state. The spring is configured to manipulate the annular body between a first condition and a second condition to selectively fix the annular body at predetermined locations along the cannula or to laterally remove the annular body from the cannula while the cannula is supported within a patient's body.
Claims20
A surgical access system, comprising:
- a surgical access device including:
- a housing;
- and
- a cannula extending from the housing;
- and
- a collar including:
- an annular body laterally attachable to the cannula and including a first hook member and a second hook member;
- and
- a spring coupled to the annular body and including a first arm and a second arm, the first arm received within the first hook member, the second arm received within the second hook member, the first and second arms positioned to move the first and second hook members relative to one another as the spring moves between an uncompressed state and a compressed state, wherein movement of the first and second hook members moves the annular body between a first condition and a second condition to selectively fix the annular body at predetermined locations along the cannula or to laterally remove the annular body from the cannula while the cannula is supported within a patient's body.
A collar for a surgical access device, the collar comprising:
- an annular body laterally attachable to a cannula of the surgical access device, the annular body including opposed hook members;
- and
- a spring coupled to the annular body and including opposed arms received within the hook members, the opposed arms positioned to move the opposed hook members relative to one another as the spring moves between an uncompressed state and a compressed state, wherein movement of the opposed hook members moves the annular body between a first condition and a second condition to selectively fix the annular body at predetermined locations along the cannula or to laterally remove the annular body from the cannula while the cannula is supported within a patient's body.
