AUXILIARY APPARATUS FOR GYNECOLOGICAL SURGERY
Abstract
The apparatus comprises a pair of flexible side bands each
curved lengthwise and each having one end turned slightly outwardly
of the plane of curvature, the opposite end of each band having an
elongated slot therein and each band also having an elongated slot
at substantially its mid portion. A pair of arcuately curved
transverse members interconnect the two side bands, by means of
pivotal connections engaged in the respective slots. The mid
portion of each transverse member is elevated relative to the rest
of the member and mounts a clamp for adjustably receiving and
clamping the arm portion of a surgical retractor blade having a
blade portion at one end. The retractor blade arms may have
elongated slots therein or may have an elongated series of
apertures therethrough to receive screws or the like of the clamp.
Each side band has a respective helical spring extending therealong
in the length between the two slots and connected at each end to
the side band. Each transverse member has two of such helical
springs extending therealong and connected at each end thereto.
These springs serve to receive and hold the nippers for tissue
fixation and also repair threads. Each transverse member is further
formed with a pair of elongated slots, one on each side of the
clamping portion, whereby a great deal of flexibility is provided
for relative adjustment of the side bands and the transverse
members.

Description
FIELD AND SUMMARY OF THE INVENTION
The present invention refers to an auxiliary apparatus for
gynecological surgery, which has been designed with special care,
in order to offer better working conditions for the surgeon and his
assistant, with resulting advantages for the patient.
The apparatus in question is utilized for gynecological operations
in the vulvo-vaginal and supra-pubic region, permitting the
presentation of surgical periods and offering a complete comfort to
the surgeon and his assistants who, in operations without such
apparatus, often take uncomfortable and tiring positions.
In fact, the apparatus in question is designed to give a good
exposure of the surgical field, affording greater facilities in
operative periods of time, through the system of spiral springs,
fixing nippers and retractors. It may even dispense with the need
for two assistants (right and left), requiring only one assistant
for handling instruments.
For an understanding of the principles of the invention, reference
is made to the following description of a typical embodiment
thereof as illustrated in the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is an exploded perspective view of the invention
apparatus;
FIG. 2 is a perspective view of the assembled apparatus; and
FIGS. 3A, 3B, 3C and 3D are perspective views of surgical
retractors constructed for use with the apparatus of the
invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
According to the invention, the auxiliary apparatus for
gynecological surgery, which is the object of this invention, is
constituted of a frame formed by two flexible side blades 1, bent
lengthwise, with one of the ends thereof being slightly turned
outwards, each blade being formed, at its opposite end, with a
longitudinal slot 2 and, between its ends, with an intermediate
slot 3. Slots 2 and 3 are designed to receive threaded pins 4
arranged to be threadedly engaged by respective nuts.
The transverse members 6 are arcuately curved, and each transverse
member is formed with a pair of elongated slots 5 arranged to
receive a threaded pin 4. Intermediate its ends, each transverse
member 5 is provided with a clamping device, such as a fork 7
having a suitable pin associated therewith for adjustably clamping
the arm portion of a surgical retractor blade, such as the blade 8,
having a blade portion at one end. By virtue of the slots 2, 3 and
5 and threaded pins 4 with their associated nuts, side bands 1 and
transverse members 6 are adjustably pivotally interconnected to
each other, it being noted that one transverse member 6 extends
between the slotted ends of the side bands 1 and the other
transverse member 6 extends between intermediate portions of the
side bands 1, whereby the side bands and the transverse members are
pivotally and adjustably interconnected to form a frame defining a
central field having an adjustable opening.
On the other hand, on side blades 1 and transverse members or rods
6, there are provided helicoidal springs 9, which may have any
diameter or length. Each transverse member 6 has two springs 9
mounted thereon and secured thereto at opposite ends of each
spring, but each side band 1 has only one spring mounted thereon
and secured thereto at its opposite ends. However, the invention
apparatus is not limited to having two springs on each transverse
member and only one spring on each side band, as any other number
of springs may be used on the side bands and on the transverse
members. The springs 9 are intended to cooperate with the surgical
retractors 10 normally used in surgery (Allis, Kelly, Backaus,
Pozzi and others).
Furthermore, in order to be better utilized, the arm portions of
retractors 10 are formed with lengthwise slots 11 or a lengthwise
series of apertures 12, which extend almost throughout the length
of the arm portion.
Thus, the side blades or bands 1 are adjusted and spaced at the
upper part of the vaginal region and at the lower part under the
gluteus muscles. The surgical retractors 10 are mounted in the
clamping devices 7, and the vaginal valves and vaginal vesicals may
be secured to these clamping device or may be connected to the
springs 9.
The substantial advantage of the apparatus in question is that the
nippers for tissue fixation and the repair threads are caught up
between the spirals of the springs nearer to each of them and may,
therefore, even eliminate the requirement or need for assistant
physicians, with the operation being entrusted solely to the
surgeon and his assistant handling the instruments.
As seen from the foregoing, the auxiliary apparatus for
gynecological surgery of the invention represents a technological
improvement of great importance for the medical field.
While a specific embodiment of the invention has been shown and
described in detail to illustrate the application of the principles
of the invention, it will be understood that the invention may be
embodied otherwise without departing from such principles.
