Definitions

  • the present invention relates to an addition or "add-on" to the standard surgical operating table. It represents a reusable module which is attached to the upper third of the operating table in order to achieve a fast and secure "beach chair positioning" for shoulder surgeries.
  • the technical problem to be solved is the "setting of a patient into a "beach chair positioning” for surgical procedures.
  • the "beach chair positioning” is a commonly used positioning for shoulder arthroplasty, arthroscopy and other surgical procedures around the shoulder joint.
  • the "beach chair position” is usually achieved by transitioning the operating table according to a "beach chair", which means that the patient is sitting upright with the back of the table flexed at 70° to 80°, the legs flexed at 30°.
  • the shoulder area of the side which is being operated upon is left free without support. In order to liberate the shoulder, one part of the operating table around the shoulder area is taken away, the part for the support of the opposite shoulder is left in place. Further, the parts of the table that support the head are also removed.
  • the head is then secured with an add on head piece which is located on a central rod which is then connected to the operating table.
  • the head is secured with straps onto that head piece, because the piece only offers support of the head from the back.
  • US 5,275,176 A discloses a shoulder arthroscopy attachment for use with a surgical table wherein the attachment may be attached to a seat section of the table in place of an articulated leg section.
  • the attachment includes a lumbar support assembly for supporting the lumbar portion of a patient's back, and a headrest assembly including an upper back support and a headrest.
  • the upper back support is adjustable in a lateral direction whereby either of a patient's shoulders may be exposed for an operation while supporting the opposite shoulder on the upper back support.
  • the headrest is adjustable relative to a frame for the headrest assembly whereby the head of a patient may be accommodated at a variety of positions.
  • This invention relates to an entire surgical operating table particularly adapted for shoulder arthroscopy. It has modular parts that can be removed, which include the shoulder area. In the shoulder area, the right and left parts can be removed, leaving a free access to the shoulder, however a central part is always remaining. This part does not allow the entire shoulder region to be free. On top of the shoulder part, there is a central part for the head. There is no included support for the patient's head or for the body such as a strap or safety belt.
  • US 2001/032364 A1 (HILL ROM SERVICES INC [US] ) relates to a surgical table having an articulated leg section with accessory attachment rails on opposite sides thereof.
  • This invention concerns a shoulder surgery attachment for the surgical table which includes a chair back assembly having a base on one end thereof and a cooperating second connector at each of its sides.

  • the chair module puts the patient in a sitting position.
  • the module is attached to the side rails with a clamp.
  • the chair module itself has two central rods. Onto the rods a part for the back support is attached, two shoulder support parts and at the top the rod which holds the head holding part. Each shoulder support can be removed separately. There is no included support for the patient onto the module such as a strap or safety belt.
  • US 2006/103226 A1 discloses a shoulder chair releasably attachable to a table including rails each mounted to the table via spacers.
  • the shoulder chair has a back portion and side plate assemblies extending from opposing sides of the back portion.
  • Each side plate assembly includes at least an inner side plate with forward and rearward slots which receive the rail spacers of the table therein.
  • This chair is comprised of a back portion and side plate assemblies extending from opposing sides of the back portion. Each side plate assembly is attached to the back plate and can be removed.
  • the head support On the upper part of the back plate there is a rod that holds the head support.
  • the head support is rather rigid, in order to allow adapting to all patients and there is no fixation strap for the head.
  • the central back portion is bulky and covers parts of the shoulder blade, even when the side portions are removed.
  • US 5,926,876 A discloses a device for adapting a surgical operating table such that the upper torso of the patient can be raised in order to place the patient in a seated position, the device further providing the means of exposing or supporting a side of said patient's upper torso and limbs.
  • the device contains a continuously adjustable positioning mechanism, and corresponding actuator for said mechanism, in a way that a user can rapidly and conveniently put a patient in the desired position, from a supine posture to a fully seated position. Additionally, the device does not render the surgical table permanently modified, as the process of modification is reversible by means of a simple attachment mechanism.
  • the device uses a back support section hingedly connected to a base frame, this base frame providing the attachment support to the surgical table.
  • Side support panels are either moved out of the way on the patient's operative side or left in place to provide support to the unaffected side. Two embodiments are described that differ solely in the way the back support surface is implemented.
  • This invention relates to a shoulder surgery attachment for the surgical table which consists of a chair back assembly. It can be used to put the patient into a sitting position up to 80° of flexion. It has a base plate and a rod that allows for the fixation on the operating table. It includes a back part that is also used for positioning of the head, and two side parts. Each side part can be removed. There is no module which secures the head or a safety strap or belt to hold the patient.
  • US 2009/307845 A1 discloses a shoulder surgery attachment for a surgical table having an articulated leg section with accessory attachment rails on opposite sides.
  • An upright chair back assembly is supported at its base or bottom end thereof for attachment to the accessory attachment rails and the chair back assembly includes a headrest assembly positioned above a back support.

  • One object of the present invention is to provide a reusable shoulder surgery add-on module adapted to be reversibly attached to the upper third of a standard surgical operating table to achieve a beach chair positioning of a patient for left or right shoulder surgery, the module being a single unit comprising 3 interconnected elements, namely a first, a second and a third element:
  • the present invention provides a fast and safe positioning of the patient for shoulder surgeries.
  • Another object of the present invention is to provide an unimpaired possibility to perform X-ray imaging of the shoulder during operating procedures because the shoulder area is free.
  • An "operating table”, sometimes called “operating room table”, is the table on which the patient lies during a surgical operation. This surgical equipment is usually found inside the surgery room of a hospital.
  • An operating table system is basically made up of three components: an operating table column, the tabletop and the transporter. Modern operating table systems are available as both stationary and mobile units. There are a wide range of table tops that can be used for both general surgery and for specialist disciplines. Mobile operating tables, however, tend to be equipped with a specific discipline in mind.
  • the base, column and tabletop form a unit.
  • the table column for a stationary operating table system is firmly anchored to the floor, the additional necessary medical devices can easily be brought to the operating area and positioned.
  • These devices include, for example, x-ray equipment, which can easily be slid under the tabletop.
  • the system offers improved leg space since disruptive foot geometry is no longer present.
  • Additional elements can be adapted to the operating table. This flexibility is very important since it enables the table to be adapted to suit the relevant patient or the surgical discipline.
  • the advantage of the mobile operating table is that the position of the table can be changed within the operating room. However, the foot of the table limits the leg space available to the surgical team.
  • the individual segments of the tabletop are adjustable and can be easily removed and replaced. They also permit x-rays and conduct electricity.
  • the head section is removable and can have a variety of attachable head rests.
  • the most common surgical position is Sitting: also known as Fowler's position, the patient in this position is sitting at a 90-degree angle. The knees are slightly flexed and the feet are placed against a padded foot board. This position is ideal for neurosurgery, facial operations, and some shoulder surgeries.
  • the “beach chair positioning” is a commonly used positioning for shoulder arthroplasty, arthroscopy and other surgical procedures around the shoulder joint.
  • the “beach chair position” is usually achieved by transitioning the operating table according to a “beach chair”, which means that the patient is sitting upright with the back of the table flexed at 70° to 80°, the legs flexed at 30°.
  • This "beach chair position” is an intermediate position between a sitting and supine position.
  • One object of the present invention is to provide a reusable shoulder surgery add-on module (13) adapted to be reversibly attached to the upper third of a standard surgical operating table (7) to achieve a beach chair positioning of a patient for left or right shoulder surgery, the module being a single unit comprising 3 interconnected elements, namely a first, a second and a third element:
  • the first element (19) further comprises a cassette for an integrated safety belt (5) located on one side of one end cap (11) and a locking mechanism for the safety belt (15) located at the opposite side of the other end cap (11).
  • the integrated safety belt (5) and the locking mechanism for the safety belt (15) are mounted at the opposite side of the end caps (11) intended to be in contact with the side rails of the operating table (7).
  • the head support element (1) comprises a helmet (16) with a flippable or pivotable visor type mean (17) to fixate the forehead of the patient.
  • the helmet (16) is garnished with a cushion material (18).
  • the cushion material (18) is a memory foam.
  • the helmet (16) is surrounded by an adjustable waist cage comprising adjustable means (not represented).
  • the adjustable means for the cage is a knob (not represented) for tightening the helmet.
  • the cage is like a bicycle helmet cage.
  • the main thing of the head support element (1) is its simplicity and the visor (17) that can be pulled up and down, so it is easy in handling and requires only a few steps and not many people holding the head and adjusting the head support element (1) as it is done now with the standard operating tables.
  • the head support element (1) comprises a helmet (16) with moveable side supports, in other words patches, for adjusting the patient's head, see figures 16 to 18 .
  • the side supports are loose. This allows placing the head inside. Them, the handwheel is turned and consequently the side supports move closer to the head until the head is safely supported. To open it up again, the locking mechanism is released, and the side support elements move aside, then the head can be released and taken out of the head support element.
  • At least the second element (2) consists in a radiolucent material.
  • the tubular rod (3) also consists in a radiolucent material.
  • the free bottoms of the two end caps (11a, 1 1b) also representing the clamp system for the attachment of the first element (19) to the side rails of the operating table (7) comprise a clamp mechanism (21).
  • a locking knob (20) for the head support element (1) is also encompassed.
  • the shoulder surgery add-on module (13) of the invention is a stable, light weighted product with radiolucent properties for X-ray and a safety belt system (5, 6, 15), said module is compatible for fixation on all standard operating tables (see figures 2 , 5 , 13 and 14 ).
  • the shoulder surgery add-on module (3) of the present invention is less complicated in handling because it is one single module, meaning shoulder and head and belt in one piece to be attached onto the side rails of the operating table (7).
  • one of the main advantages is the shoulder supporting element (2) with the displaceable shoulder support element, for instance flippable or pivotable locking mechanism or sliding and locking mechanism.
  • Another advantage is the integrated safety belt for the body as well as the integrated fixation of the head (1) with a visor type strap (17) and helmet (16).
  • the prior art only discloses either a head rest or a complicated assembly with a strap. Also, most of the disclosures of the prior art do not allow the shoulder which is being operated on completely free but there remains a central back support that can interfere with x-rays for example.
  • One advantage of the present invention is to provide a single unit, simple, easy to handle module for "beach chair positioning" in shoulder surgery in the form of an add-on to the standard operating table (7).
  • This single unit module can be securely attached to the standard side rails which are located on both sides of the operating table (7).
  • the shoulder surgery add-on module (13) the end caps (11) of the first element (19) are slid onto the rails on both sides of the upper third of the operating table (7).
  • the current invention is one single unit module which is composed of three main parts or elements.
  • the first element (19) or bottom element is the base element or shaft with the fixation mechanism for the attachment to the side rails of the operating table (7).
  • the shaft consists in a rod in square shape (14) forming a "fork” or “U” like shape and a tubular rod (3) for supporting the two other elements (see figures 2, 3 , 5 , 6 , 12 , 13 and 14 ).
  • the second element or middle shoulder support element (2) being a displaceable element for supporting of the shoulder and shoulder blade area, the displacement, preferably from left to right or vice versa, being for instance a flip with rotation around the rod or a slide relative to the rod.
