Abstract
Embodiments of the present disclosure relate to cannula insertion systems for inserting a plurality of cannulas into a target tissue.
Claims15
A cannula insertion system, comprising:
- a housing comprising a proximal end and a distal end, the distal end of the housing comprising an opening;
- a plurality of shafts disposed within the housing, each of the plurality of shafts comprising a proximal end and a distal end;
- and
- a blade disposed at the distal end of each of the plurality of shafts, wherein:
- each of the plurality of shafts is configured to axially translate between a retracted position and an extended position;
- the blade at the distal end of each of the plurality of shafts extends beyond the opening of the housing when the respective shaft of the plurality of shafts is in the extended position;
- and
- the distal end of each of the plurality of shafts is further configured to support a cannula around the blade.

A cannula insertion system, comprising:
- a housing comprising a proximal end and a distal end, the distal end of the housing comprising an opening;
- a first shaft disposed within the housing, the first shaft comprising a proximal end and a distal end;
- a blade disposed at the distal end of the first shaft;
- a plurality of second shafts disposed within the housing, each of the plurality of shafts comprising a proximal end and a distal end;
- and
- a plurality of compartments formed in the housing, each of the plurality of compartments configured to retain a cannula, wherein:
- the first shaft is configured to axially translate between a retracted position and an extended position;
- the blade at the distal end of the first shaft extends beyond the opening of the housing when the first shaft is in the extended position;
- each of the plurality of second shafts is configured to axially translate to an activated position;
- and
- in the activated position, each of the plurality of second shafts is configured to release the cannula from a respective compartment of the plurality of compartments for loading the cannula onto the blade at the distal end of the first shaft.

A cannula insertion system, comprising:
- a housing comprising a proximal end and a distal end;
- a shaft disposed within the housing, the shaft comprising a proximal end and a distal end;
- a blade disposed at the distal end of the shaft;
- and
- a cylinder disposed at the distal end of the housing, the cylinder comprising a plurality of compartments, wherein:
- each of the plurality of compartments is configured to retain a cannula;
- the cylinder is configured to rotate about an axis and to a plurality of rotational positions;
- one of the plurality of compartments is aligned with the shaft in each of the plurality of rotation positions of the cylinder;
- the shaft is configured to axially translate between a retracted position and an extended position;
- and
- in the extended position, the shaft is configured to extend through the one of the plurality of compartments aligned with the shaft for loading and inserting the cannula.
