Abstract

Abstract A probe and suction device for use during surgery is disclosed. The device includes an elongated tubular handle adapted for connection to a source of suction and a separable elongated tubular probe and suction member. It includes a suction regulating orifice in the handle and is characterized by a positive snap-on rotatable connection between the handle and the probe and suction member. The digital end of the probe and suction member is blunted to avoid tissue damage.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 203 words
A surgical probe and suction device comprising: (A) an elongated tubular handle having a central longitudinal passage and means at one end for connection to a vacuum source, (B) a suction regulating orifice in said handle communicating with said central passage, (C) a separable elongated tubular probe and suction member connected to the opposite end of said handle and having an open passage therethrough, (D) a positive snap-on rotatable connection between said handle and probe and suction member, said connection comprising: (1) a tapered male connection member extending from the probe or the handle having a central passage therethrough, (2) an annular groove around said male connection member spaced from the end thereof, (3) a mating female connection member adapted to receive and engage said male connection member extending from the other of said probe or handle and comprising: (a) an annular ring having a plurality of parallel resilient finger members closely and uniformly spaced apart about a central passage, and (b) an inwardly directed lip at the ends of each of said finger members adapted to engage the annular groove around said male connection member, and (E) a blunted distal end on said probe and suction member surrounding the open passage therein.
Claim 2
Dependent Claim 203 words
A surgical probe and suction device comprising: (A) an elongated tubular handle having a central longitudinal passage and means at one end for connection to a vacuum source, (B) a suction regulating orifice in said handle communicating with said central passage, (C) a separable elongated tubular probe and suction member connected to the opposite end of said handle and having an open passage therethrough, (D) a positive snap-on rotatable connection between said handle and probe and suction member, said connection comprising: (1) a tapered male connection member extending from the probe or the handle having a central passage therethrough, (2) an annular groove around said male connection member spaced from the end thereof, (3) a mating female connection member adapted to receive and engage said male connection member extending from the other of said probe or handle and comprising: (a) an annular ring having a plurality of parallel resilient finger members closely and uniformly spaced apart about a central passage, and (b) an inwardly directed lip at the ends of each of said finger members adapted to engage the annular groove around said male connection member, and (E) a blunted distal end on said probe and suction member surrounding the open passage therein.
