Abstract
Methods and apparatus for treating bones, including, in one or more embodiments, a device for delivering a bone filler material comprising: a housing having a throughbore; a plunger comprising a shaft having external threads, wherein the plunger is configured for advancement through the throughbore of the housing; and a threaded receiving member configured to releasably engage the plunger. Methods for removing an instrument from a vertebral body comprising applying ultrasonic energy to the instrument, wherein a distal end of the instrument is disposed in a cavity in the vertebral body, wherein the cavity contains a filler material; and removing the instrument from the vertebral body.
Claims20
A device for delivering a bone filler material comprising:
- a housing including a body having a throughbore and an upper chamber that intersects the throughbore;
- a plunger comprising a shaft having external threads, wherein the plunger is configured for advancement through the throughbore of the housing;
- a receiving member disposed in the upper chamber and configured to releasably engage the plunger;
- and
- an actuator rod assembly including an actuator rod and an actuator spring, the actuator rod extending from the upper chamber and the actuator spring disposed over the actuator rod which is configured to engage the receiving member,
- wherein the receiving member is configured to translate within the upper chamber from an engaged position where the receiving member engages the plunger to a disengaged position where the receiving member is not engaged with the plunger.
A device for delivering a bone filler material comprising:
- a housing including a throughbore;
- a plunger comprising a shaft having external threads, wherein the plunger is configured for advancement through the throughbore of the housing;
- and
- a threaded receiving member disposed in the housing and configured to releasably engage the plunger, wherein the threaded receiving member comprises a body having a bore, wherein the bore comprises a first threaded portion, a first smooth portion opposite the first threaded portion, a second threaded portion, and a second smooth portion opposite the second threaded portion, wherein a spring biases the first and second threaded portions into engagement with the plunger during the step of advancing the plunger into the throughbore, and wherein disengaging the threaded receiving member comprises rotating the body about a fulcrum to disengage the first and second threaded portions from the plunger such that the first and second smooth portions allow axial translation of the plunger.
A device for delivering a bone filler material comprising:
- a housing including a body having a throughbore and a chamber that intersects the throughbore;
- a plunger configured for advancement through the throughbore of the housing;
- a lower receiving member disposed in the chamber and configured to releasably engage the plunger, wherein a spring biases the lower receiving member into engagement with the plunger;
- and
- an actuator configured to engage the lower receiving member when the actuator is depressed and applies pressure to the spring.
