SURGICAL RETRACTOR
Abstract
A surgical retractor includes an elongated body having a handle
portion, a retractor arm connected to the handle portion, a
retractor tip at an end of the retractor arm, and a suction
connector extending through a wall of the handle portion. An inner
retractor cavity extends within the retractor from the suction
connector to an opening at an outer surface of the retractor tip.
The suction connector can be selectively connected to an external
suction or vacuum device. The surgical retractor can be used to
hold and/or move tissues to expose a surgical field and to collect
blood, fluid, smoke, and/or surgical debris from a surgical
field.

Description
BACKGROUND
1. Field
[0001] The disclosure of the present patent application relates to
a surgical instrument, and particularly, to a surgical retractor
with suction for orthopedic surgery.
2. Description of the Related Art
[0002] Surgical retractors may be employed during a surgical
treatment to provide access and visualization of a surgical site.
Such retractors space apart and support tissue and/or other
anatomical structures to expose anatomical structures adjacent the
surgical site and/or provide a surgical pathway to the surgical
site.
[0003] In orthopedic surgeries, an orthopedic surgical retractor,
e.g., a cobb retractor, is typically used to retract, hold, and
reposition skin, muscle, and/or other tissue to expose a surgical
field. Retraction is generally accompanied by operation of a
separate suction device by an assistant. The suction device is used
to collect fluid, smoke, and/or surgical debris from the surgical
field.
[0004] Often times, operation of a surgical retractor and a
separate suction device can be cumbersome. Additionally, the
assistant operating the suction device can hamper free movement of
the operator and/or block the operator's view of the surgical
field.
[0005] Thus, a surgical retractor with suction solving the
aforementioned problems is desired.
SUMMARY
[0006] A surgical retractor includes a generally elongated or
cylindrical body having a handle portion, a retractor arm connected
to the handle portion, a retractor tip at an end of the retractor
arm, and a suction connector extending through a side of the handle
portion. An inner retractor cavity extends within the retractor
from the suction connector to an opening at an outer surface of the
retractor tip. The suction connector can be selectively connected
to an external suction or vacuum device. The surgical retractor can
be used to hold and/or move skin, muscle, and soft tissues to
expose a surgical field and to collect blood, fluid, smoke, and/or
surgical debris from the surgical field.
[0007] These and other features of the present disclosure will
become readily apparent upon further review of the following
specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] A surgical retractor or "cobb" retractor 10, according to
the present teachings, is a surgical instrument that can be used
during a surgical procedure to move or space apart skin, muscle,
and/or other tissue that block a surgical field. The surgical
retractor 10 is particularly useful for orthopedic surgical
procedures, such as spine, arthroplasty, and other orthopedic
surgeries.
[0017] As shown in FIGS. 1-7, the surgical retractor 10 includes a
generally elongated or cylindrical body having a handle portion 12,
a retractor arm 14 connected to the handle portion 12, a retractor
tip 17 at an end of the retractor arm 14, and a suction connector
16 extending through a side of the handle portion 12. An inner
retractor cavity 18 (FIGS. 4-5) extends within the retractor from
the suction connector 16 to an opening 20 at an outer surface of
the retractor tip 17. The suction connector 16 can be selectively
connected to an external suction or vacuum device. The surgical
retractor 10 can be used to hold and/or move skin, muscle, and soft
tissues to expose a surgical field and collect blood, fluid, smoke,
and/or surgical debris from a surgical field.
[0018] The retractor arm 14 can be generally linear or elongated. A
diameter of the retractor arm 14 can be tapered, e.g., the diameter
of the arm 14 proximate the handle portion 12 can be greater than
the diameter of the arm 14 proximate the retractor tip 17. The
handle portion 12 can have a larger diameter than the retractor arm
14. The suction connector 16 can extend normal to the handle
portion 12. For example, the suction connector 16 can extend from a
peripheral sidewall of the handle portion 12. The suction connector
16 can be disposed closer to the retractor arm 14 than the free end
of the handle portion 12. In this manner, the suction connector 16
does not compromise the surgical field, while being easily
accessible to the operator. The suction connector 16 can include
threads or ridges 22a, 22b to facilitate connection with an
external suction device.
[0019] The retractor tip 17 can include a generally flat, inner
surface 24a and a curved or convex outer surface 24b. The retractor
tip 17 can further include a wide, curved edge 19. The opening 20
defined in the outer surface 24b of the tip 17 extends to the inner
cavity 18. The opening 20 can be semi-circular. The inner cavity 18
can include a soft curve to connect the tip to the suction
connector 16. Preferably, the inner cavity 18 is devoid of sharp
angles or bends to prevent or minimize the occurrence of blockages
as materials are suctioned through the tube.
[0020] The retractor 10 can be formed from any suitable, surgical
grade material. For example, the retractor 10 can be formed from a
metal material, such as, stainless steel, titanium, or tungsten
carbide. Preferably, the metal material is corrosion resistant,
e.g., inox steel. The retractor 10 can be formed from a disposable
material, such as a disposable, plastic material. The retractor 10
can have any suitable dimensions, e.g., a length of about 24
centimeters. According to some embodiments, the retractor 10 can be
configured to have an adjustable length.
[0021] The retractor 10 can be used during a surgical procedure to
both retract tissue and collect debris from a surgery site.
Accordingly, use of the retractor 10 obviates the need for carrying
out these functions using two separate instruments, e.g., a
conventional retractor and a conventional suction device. As the
retractor 10 alone can perform functions which previously
necessitated the use of two separate instruments, an operator can
utilize cautery instruments to cut tissue with greater ease than
was previously possible. Further, an operator using the retractor
10 will not have to rely on the assistance of another individual to
operate a separate suction device.
[0022] It is to be understood that the surgical retractor with
suction for orthopedic surgery is not limited to the specific
embodiments described above, but encompasses any and all
embodiments within the scope of the generic language of the
following claims enabled by the embodiments described herein, or
otherwise shown in the drawings or described above in terms
sufficient to enable one of ordinary skill in the art to make and
use the claimed subject matter.
