Abstract

An apparatus for applying a vacuum during a surgical procedure can include a vacuum pump assembly having a port, a first housing, a second housing, a first silencer or tubular magnet and a second silencer. The first housing can define a first cavity receiving the vacuum pump assembly therein. A portion of the first housing can be formed by a portion of the port. The second housing can define a second cavity receiving the first housing therein. A portion of the second housing can be formed by a second portion of the port. The first silencer or tubular magnet can be coupled to the first housing and can have a longitudinal extent along a longitudinal axis. The first silencer or tubular magnet can extend from the first housing within the second cavity. The second silencer can be coupled to the second housing and can have a longitudinal extent along a longitudinal axis. The second silencer can extend from the second housing within second cavity.

First claim

The claimed invention is:

1. An apparatus for applying a vacuum during a surgical procedure, the apparatus comprising:
a vacuum pump assembly including a port;
a first housing defining a first cavity receiving the vacuum pump assembly therein, a portion of the first housing formed by a portion of the port;
a second housing defining a second cavity receiving the first housing therein, wherein a portion of the second housing is formed by a second portion of the port;
a first silencer or a tubular magnet coupled to the first housing and having a longitudinal extent along a longitudinal axis, wherein the first silencer or tubular magnet is screwed into a first aperture in the first housing with a first threaded section located at a first longitudinal end portion, wherein the first silencer or tubular magnet extends from the first housing within the second cavity along the longitudinal axis, and wherein the first silencer or tubular magnet is contacted only at the first longitudinal end portion thereof; and
a second silencer coupled to the second housing and having a longitudinal extent along a longitudinal axis, wherein the second silencer is screwed into a second aperture in the second housing with a second threaded section located at a second longitudinal end portion, wherein the second silencer extends from the second housing toward the first silencer or tubular magnet within the second cavity, and wherein the second silencer is contacted only at the second longitudinal end portion thereof.

2. The apparatus of claim 1 , wherein first housing and the second housing are each configured as a box enclosure and are each formed of a same polymer material.

3. The apparatus of claim 1 , further comprising a plurality of mounts configured to couple the first housing to the second housing, wherein the plurality of mounts are positioned on a first side of the first housing and on a second opposing side of the first housing.

4. The apparatus of claim 1 , wherein the longitudinal axis of the first silencer is oriented substantially transverse to the longitudinal axis of the second silencer.

5. The apparatus of claim 4 , wherein the first silencer or tubular magnet is offset a distance from the second silencer in a direction that is substantially transverse to the longitudinal axis of the first silencer or tubular magnet and the longitudinal axis of the second silencer, and wherein the offset is such that the longitudinal axis of the first silencer or tubular magnet does not intersect with the longitudinal axis of the second silencer.

6. The apparatus of claim 1 , wherein the second silencer comprises a plurality of silencers.

7. A system for use during a surgical procedure, the system comprising:
a vacuum pump assembly;
a first housing defining a first cavity configured to receive the vacuum pump assembly therein;
a second housing defining a second cavity configured to receive the first housing therein;
a first silencer or tubular magnet configured to couple to the first housing and having a longitudinal extent along a longitudinal axis, wherein the first silencer or tubular magnet is screwed into a first aperture in the first housing with a first threaded section located at a first longitudinal end portion, wherein the first silencer or tubular magnet when coupled to the first housing extends outward from the first housing within the second cavity along the longitudinal axis, and wherein the first silencer or tubular magnet is contacted only at the first longitudinal end portion thereof; and
a second silencer configured to couple to the second housing and having a longitudinal extent along a longitudinal axis, wherein the second silencer is screwed into a second aperture in the second housing with a second threaded section located at a second longitudinal end portion, wherein the second silencer, when coupled to the second housing, extends inward from the second housing toward the first silencer or tubular magnet within the second cavity, wherein the second silencer is contacted only at the second longitudinal end portion thereof, and wherein the longitudinal axis of the first silencer or tubular magnet is substantially transverse to the longitudinal axis of the second silencer when the first silencer or tubular magnet is coupled to the first housing and the second silencer is coupled to the second housing.

8. The system of claim 7 , wherein a port of the vacuum pump assembly forms portions of or are integrated with the first housing and the second housing.

9. The system of claim 7 , further comprising a plurality of mounts configured to couple the first housing to the second housing, wherein the plurality of mounts are positioned on a first side of the first housing and on a second opposing side of the first housing.

10. The system of claim 7 , wherein the second silencer is offset a distance from the first silencer or tubular magnet in a direction that is substantially transverse to the longitudinal extent of the first silencer or the tubular magnet and the longitudinal extent of the second silencer, and wherein the offset is such that the longitudinal axis of the first silencer or tubular magnet does not intersect with the longitudinal axis of the second silencer.

11. The system of claim 7 , wherein at least the second silencer comprises a plurality of silencers.

12. The system of claim 7 , wherein first housing and the second housing are each configured as a box enclosure and are each formed of a same polymer material.

13. A method for reducing noise during a surgical procedure, the noise resulting from operation of a vacuum pump, the method comprising: positioning an assembly including the vacuum pump within a surgical suite, the assembly comprising: a first housing having a cavity receiving the vacuum pump; a first silencer or tubular magnet mounted to the first housing only at a first end portion thereof, a second housing having a second cavity receiving the first housing, wherein the first housing is mounted within the second housing by a plurality of mounts configured to couple the first housing to the second housing, wherein the plurality of mounts are positioned on a first side of the first housing and on a second opposing side of the first housing; and a second silencer mounted to the second housing only at a second end portion thereof and extending with a longitudinal axis positioned substantially transverse to a longitudinal axis of the first silencer or the tubular magnet, wherein the second silencer extends from the second end portion toward the first silencer; wherein the first silencer or tubular magnet is contacted only at the first end portion and the second silencer is contacted only at the second end portion such that the first silencer or tubular magnet and the second silencer freely extend within the second cavity.

14. The method of claim 13 , further comprising passing air through an inlet of the vacuum pump that forms portions of the first housing and the second housing as the first housing and the second housing are molded around the inlet.

15. The method of claim 13 , wherein the second silencer is offset a distance from the first silencer or tubular magnet in a direction that is substantially transverse to a longitudinal extent of the first silencer or tubular magnet and the longitudinal extent of the second silencer.

16. The method of claim 13 , wherein the second silencer comprises a plurality of silencers.
