Abstract
Abstract A speculum with an upper spatula and a lower spatula interacting therewith, which spatulas each comprise a spatula part intended for vaginal introduction and a handle part extending essentially perpendicularly thereupon. One handle part surrounds the other handle part in such a way that the two handle parts are displaceable only longitudinally in relation to each other for moving the spatula parts towards and away from each other and the surrounded handle part has at its end facing away from the spatula a longitudinally extending slot for accommodating an arresting body which is adapted, by being introduced into the slot, to effecting an expansion of the surrounded handle part in order to prevent any movements of said surrounded handle part in relation to the surrounding handle part.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A speculum with an upper spatula (1) and a lower spatula (2) interacting therewith, which spatulas each comprise a spatula part (3 and 4, respectively,) intended for vaginal introduction and a handle part (5 and 6, respectively,) exTending essentially perpendicularly thereupon, which handle parts (5,6) are engagingly connected with each other in such a way that they are mutually displaceable in their longitudinal direction for moving the spatula parts (3,4) towards and away from each other, characterized in that the one handle part (6) surrounds the other handle part (5) in such a way that the two handle parts (5,6) are displaceable only longitudinally in relation to each other, in addition to which the surrounded handle part (5), at its end facing away from the spatula (3), has a longitudinally extending slot (8) for accommodating an arresting body (11) which is adapted, by being introduced into the slot (8), to effecting an expansion of the surrounded handle part (6).
Claim 2
Dependent Claim
159 words
A speculum with an upper spatula (1) and a lower spatula (2) interacting therewith, which spatulas each comprise a spatula part (3 and 4, respectively,) intended for vaginal introduction and a handle part (5 and 6, respectively,) exTending essentially perpendicularly thereupon, which handle parts (5,6) are engagingly connected with each other in such a way that they are mutually displaceable in their longitudinal direction for moving the spatula parts (3,4) towards and away from each other, characterized in that the one handle part (6) surrounds the other handle part (5) in such a way that the two handle parts (5,6) are displaceable only longitudinally in relation to each other, in addition to which the surrounded handle part (5), at its end facing away from the spatula (3), has a longitudinally extending slot (8) for accommodating an arresting body (11) which is adapted, by being introduced into the slot (8), to effecting an expansion of the surrounded handle part (6).
Claim 3
Dependent Claim
93 words
A speculum as claimed in claim 1, characterized in that each of the handle parts (5,6) has an essentially U-shaped cross section and in that the edge parts on the surrounding handle part (6) have radially inwardly extending parts (7), so that the edge parts on the surrounded handle part (5) rest loosely against the inside of the inwardly extending parts (7) on the surrounding handle part (6), and in that the slot (8) serving to accommodate the arresting body (11) is constructed between these edge parts on the surrounded handle part (5).
Claim 4
Dependent Claim
63 words
A speculum as claimed in claim 1 or 2, characterized in that in the surrounded handle part (5), in the area of the slot (8), a groove (15) has been constructed for accommodating the arresting body (11) which is displaceable in the longitudinal direction of handle parts (5,6), which arresting body (11) has a projecting part (13) which extends into the slot (8).
Claim 5
Dependent Claim
45 words
A speculum as claimed in claim 3, characterized in that the slot (8) has at least one expanded part in which the width of the slot (8) is larger than or equal to the diameter of the part (13) projecting from the arresting body (11).
