Abstract
Abstract A medical instrument particularly designed for manipulating and positioning the human uterus during a laparoscoptomy. The device is generally similar to the conventional Simms cervical tenaculum and includes a generally cup-shaped member whose end wall is connected to a source of vacuum through a tube or the like. Within the member is a conical element to which a plurality of different size tips may be releasably connected. The instrument is inserted through the vaginal passage and the cone placed against the cervical os, and the vacuum in the cup member causes the uterus to adhere to the cone. The tip, which is now in the uterus, and which is connected to the rigid tube, may be manipulated by corresponding movement of the tube.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
93 words
A device of the character described comprising a member having an end wall, a continuous side wall extending axially outwardly from the periphery of said end wall, an element extending axially from a central portion of said end wall and spaced radially inwardly from said side wall to define a continuous space therebetween, a tip extending axially from said element, a rigid tube connected to said end wall and extending in a contra direction to said side wall, and means defining a passage placing said tube and said continuous space in flow communication.
Claim 2
Independent Claim
93 words
A device of the character described comprising a member having an end wall, a continuous side wall extending axially outwardly from the periphery of said end wall, an element extending axially from a central portion of said end wall and spaced radially inwardly from said side wall to define a continuous space therebetween, a tip extending axially from said element, a rigid tube connected to said end wall and extending in a contra direction to said side wall, and means defining a passage placing said tube and said continuous space in flow communication.
Claim 3
Dependent Claim
26 words
A device as set forth in claim 1, in which said tip is releasably connected to said element whereby tips of different sizes may be used.
Claim 4
Dependent Claim
19 words
A device as set forth in claim 1, in which said tip is curved along the axial extent thereof.
Claim 5
Dependent Claim
33 words
A device as Set forth in claim 1 in which said element has a distal end wall disposed in a transaxial direction and generally coterminous with the distal end of said side wall.
Claim 6
Dependent Claim
25 words
A device as set forth in claim 4 in which said element is of generally frusto-conical configuration with its maximum dimension adjacent said end wall.
Claim 7
Dependent Claim
16 words
A device as set forth in claim 1 in which said passage extends through said element.
Claim 8
Dependent Claim
38 words
A device as set forth in claim 4 in which said element has a tapped hole extending to the end wall thereof, and said tip is provided with a threaded end portion releasably engageable with said tapped hole.
Claim 9
Dependent Claim
26 words
A device as set forth in claim 1 in which said tube is provided with a manually engageable orienting plate axially spaced from said end wall.
Claim 10
Dependent Claim
44 words
A device as set forth in claim 8 in which said tip is curved along its axial extent, and releasably connected to said element, and in which said plate is disposed in a predetermined angular orientation with respect to the curvature of said tip.
