First Claim
Patent Images
1. A cannula retaining device, comprising:
- a substantially flat base including a cylindrical hollow sleeve about a central axis, through which a cannula means can be inserted; and
clamp means registering in the hollow sleeve and including compressible means having a cannula receiving clamp aperture about the cannula axis, the clamp means further including engageable arm means extending perpendicularly to the axis for selectively compressing the compressible means.

Abstract
A cannula retaining device is disclosed in which a base includes a sleeve in the center thereof to provide a port for insertion of a cannula. A clamp including a compressible plug with an interior aperture that matches the diameter of the cannula is fitted into the base. The clamp includes a pair of laterally extending finger engageable arms which tighten the compressible plug on the cannula, thereby receiving the cannula while allowing adjustment, angulation and rotation.

15. A cannula retaining device for use in laparoscopic and other applications, comprising:
-
a body attachment member having a seating flange and an integral cylindrical sleeve extending outwardly therefrom about a desired axis, the member including sinuous means at the region of juncture of the sleeve to the flange, the sleeve further comprising an inner wall of predetermined dimensions; clamp means including a depending hollow cylinder mating within the inner wall of the sleeve, and a open upper locking loop integral therewith extending transversely relative to the axis, and having means for securing the loop at different compression positions with a varying diameter wall portion being defined thereby; and a cannula retainer of pliable material disposed within the wall portion of the clamp means, the retainer having a central vertical aperture sized to receive a cannula, whereby the axis, rotational and angular orientations of the cannula can be varied without weakening securement at the attachment member.

16. A device for enabling securement and manipulation of a cannula penetrating a body wall along a cannula axis, comprising:
-
a support member having a pad for adhesive attachment to the body area about the cannula penetration area, the support member including a flexible base and an upstanding sleeve about the penetration area; a clasp member having a compressible loop-shaped body comprising a wall defining a substantially circular arc segment and a pair of spaced-apart arms having end engagement means, the clasp member being resiliently deformable and compressible to different positions to diminish the arc segment, the clasp member further including a depending tubular sleeve member rotatable within a female sleeve member; and resiliently compressible cannula retainer means having a central aperture size to receive the cannula and fitting within the arc segment of the clasp member such that the cannula is retained when the arms are engaged at their ends, wherein one arm has an L-shaped terminal segment and teeth along the base of the L and the other arm has an offset end configured to engage in the teeth such that the clasp can be tightened/compressed to a desired degree by inward flexure at the arms and released by outward bending of a tip of the L-shaped segment.
