Cervix stabilizing device

1 . A method of using a cervix stabilizing device, the method comprising:

holding a handle of the cervix stabilizing device in a single hand, the cervix stabilizing device comprising:

the handle comprising a handle body, the handle comprising:

a compartment within the handle body;

a plunger comprising a stopper that forms a seal against an inner wall of the compartment; and

an actuation assembly comprising a scroll wheel operatively connected to the plunger and extending outward from a sidewall of the handle body, the scroll wheel configured to be manually rotated relative to the sidewall of the handle body to retract the stopper within the compartment to increase a volume in the compartment distal of the stopper, which is used to generate a negative pressure in the compartment when the cervix stabilizing device is in use;

wherein the scroll wheel and a worm gear are on an axle extending in a longitudinal direction of the plunger, and the worm gear is configured to drive a middle wheel directly engaged with a straight gear of the plunger to retract the stopper and generate the negative pressure; and

a shaft connected to a distal end of the handle body and having a lumen extending therethrough that is in communication with the compartment such that negative pressure is increased in the lumen due to the negative pressure in the compartment; and

a cervical interface on a distal end of the shaft configured to generate a seal against cervical tissue using the negative pressure in the lumen;

placing the cervical interface on cervical tissue using the single hand;

actuating the actuation assembly with the single hand with the cervical interface sealed against the cervical tissue thereby generating the negative pressure in the compartment.

2 . The method of claim 1 further comprising releasing the negative pressure from the compartment using a pressure release button by actuating the pressure release button using the single hand.

3 . The method of claim 2 , wherein the pressure release button having a closed position configured to seal a hole through the sidewall that is in communication with the compartment and an open position that opens the hole through the sidewall.

4 . The method of claim 3 , wherein a position of the scroll wheel defines a front of the handle and the pressure release button is on a side of the handle.

5 . The method of claim 2 , wherein the pressure release button comprises a lever having a user end that extends from a pivot location of the pressure release button toward a proximal end of the handle.

6 . The method of claim 1 , further comprising rotating the scroll wheel with the single hand to retract the stopper.

7 . The method of claim 1 further comprising disassembling the shaft from the handle body and the cervical interface from the shaft for a cleaning operation.

8 . A cervix stabilizing device, comprising:

a handle comprising a handle body, the handle comprising:

a compartment within the handle body;

a plunger comprising a stopper that forms a seal against an inner wall of the compartment; and

an actuation assembly comprising a scroll wheel operatively connected to the plunger and extending outward from a sidewall of the handle body, the scroll wheel configured to be manually rotated relative to the sidewall of the handle body to retract the stopper within the compartment to increase a volume in the compartment distal of the stopper, which is used to generate a negative pressure in the compartment when the cervix stabilizing device is in use; and

wherein the scroll wheel and a worm gear are on an axle extending in a longitudinal direction of the plunger, and the worm gear is configured to drive a middle wheel directly engaged with a straight gear of the plunger to retract the stopper and generate the negative pressure; and

a shaft connected to a distal end of the handle body and having a lumen extending therethrough that is in communication with the compartment such that negative pressure is increased in the lumen due to the negative pressure in the compartment.

9 . The cervix stabilizing device of claim 8 further comprising a pressure release button having a closed position configured to seal a hole through the sidewall that is in communication with the compartment and an open position that opens the hole through the sidewall.

10 . The cervix stabilizing device of claim 9 , wherein a position of the scroll wheel defines a front of the handle and the pressure release button is on a side of the handle.

11 . The cervix stabilizing device of claim 9 , wherein the pressure release button comprises a lever having a user end that extends from a pivot location of the pressure release button toward a proximal end of the handle.

12 . The cervix stabilizing device of claim 8 further comprising a stop carried by the straight gear that is configured to prevent movement of the plunger relative to the middle wheel in a proximal direction.
