Drain inserter

Claim 2

A drain inserter for use in surgical operations for placement of a conventional tubular suction catheter of the type having perforations at or adjacent to one end thereof in a patient, said drain inserter comprising an elongate, relatively thin, body having a handle at one end and a longitudinal extension at the other or distal end thereof, said longitudinal extension being of sufficiently small cross sectional dimension to permit easy insertion thereof into one of said perforations whereby to attach the perforated end portion of said catheter releasably to said other end of said body, and retaining means adjacent to said handle adapted to receive and hold said catheter when the latter is stretched tautly between the said extension and said retaining means, said body being of a material that is easily flexible to permit insertion of the portion thereof remote from said handle through an incision and placement of the perforated end of said catheter at a desired location in the body of the patient, said retaining means being readily releasable thereafter from said catheter to permit withdrawal of said body through said incision independently of said catheter and consequential retraction of said extension from the perforation engaged thereby without disturbing the position and orientation of the catheter and particularly the perforated end thereof in said patient, said body being substantially half as wide as said handle at the juncture thereof with said handle, said body extending longitudinally from one half-portion only of said handle, said handle defining a transverse shoulder at the juncture thereof with said body, said shoulder being stepped back at the side edge of said handle laterally remote from said body, and said step being of the same size and shape as said longitudinal extension.

Claim 3

A drain inserter as defined by claim 1 wherein said body is tapered uniformly from said handle toward said longitudinal extension.

Claim 4

A drain inserter as defined by claim 2 wherein said body and said handle are of essentially thin sheet metal.

Claim 5

A drain inserter for use in surgical operations for placement of a conventional tubular suction catheter of the type having perforations at or adjacent to one end thereof in a patient, said drain inserter comprising an elongate, relatively thin, body having a handle at one end and a longitudinal extension at the other or distal end thereof, said longitudinal extension being of sufficiently small cross sectional dimension to permit easy insertion thereof into one of said perforations whereby to attach the perforated end portion of said catheter releasably to said other end of said body, and retaining means adjacent to said handle adapted to receive and hold said catheter when the latter is stretched tautly between the said extension and said retaining means, said body being of a material that is easily flexible to permit insertion of the portion thereof remote from said handle through an incision and placement of the perforated end of said catheter at a desired location in the body of the patient, said retaining means being readily releasable thereafter from said catheter to permit withdrawal of said body through said incision independently of said catheter and consequential retraction of said extension from the perforation engaged thereby without disturbing the position and orientation of the catheter and particularly the perforated end thereof in said patient, said longitudinal extension being disposed substantially medianly of said body and substantially flush with the top surface thereof, said body being provided in the top surface thereof with grooves extending longitudinally rearwardly from the forward end of the body and at opposite sides of said longitudinal extension, and said grooves defining a narrow ridge directly behind said extension for supporting the portion of the catheter adjacent to the perforation in which the extension is inserted, whereby to minimize the drag of said body against said catheter when said inserter is retracted to withdraw the extension from said perforation and to minimize any tendency of the retracting motion to disturb the positioned end of the catheter.

Claim 6

A drain inserter for use in surgical operations for placement of a conventional tubular suction catheter of the type having perforations at or adjacent to one end thereof in a patient, said drain inserter comprising an elongate, relatively thin, body having a handle at one end and a longitudinal extension at the other or distal end thereof, said longitudinal extension being of sufficiently small cross sectional dimension to permit easy insertion thereof into one of said perforations whereby to attach the perforated end portion of said catheter releasably to said other end of said body, and retaining means adjacent to said handle adapted to receive and hold said catheter when the latter is stretched tautly between the said extension and said retaining means, said body being of a material that is easily flexible to permit insertion of the portion thereof remote from said handle through an incision and placement of the perforated end of said catheter at a desired location in the body of the patient, said retaining means being readily releasable thereafter from said catheter to permit withdrawal of said body through said incision independently of said catheter and consequential retraction of said extension from the perforation engaged thereby without disturbing the position and orientation of the catheter and particularly the perforated end thereof in said patient, said longitudinal extension being disposed substantially medianly of said body and substantially flush with the top surface thereof, said body being provided in the top surface thereof with grooves extending longitudinally rearwardly from the forward end of the body and at opposite sides of said longitudinal extension, and said grooves defining a narrow ridge directly behind said extension for supporting the portion of the catheter adjacent to the perforation in which the extension is inserted, whereby to minimize the drag of said body against said catheter when said inserter is retracted to withdraw the extension from said perforation and to minimize any tendency of the retracting motion to disturb the positioned end of the catheter.
