BODY SUPPORT DEVICE FOR SURGERY

Abstract

The present application discloses a body support device for surgery with a dynamic support for the torso. This device stimulates the adoption of a more natural posture and provides the dissipation of the load placed on the bone and muscle structures in the spinal column through the combination of the torso support (1) to the posterior support (13). The posterior support (13) consists of the systematization of the human vertebral column, comprising a set of segments (13) chained and aligned by the passage of an elastic medium (14) therein, controlled by the user's action. Thus, this technology allows for minimizing surgeon's physical fatigue resulting from a prolonged posture in surgery.

DESCRIPTION OF EMBODIMENTS

[0092] Referring to the drawings, herein are described an optional embodiment in more detail, which however is not intended to limit the scope of the present application. The embodiment refers to the use of the body support device in ophthalmological surgeries in operating room.

[0093] The present technology discloses one torso support (1) which is placed on the surgeon's torso, allowing freedom of movement of the upper limbs. The shape of torso support (1) is designed from scanning the surgeon's back and corresponds, approximately, to a prosthesis for the user's back which provides precise attaching and correction of postural habits shown to cause pain and muscle fatigue.

[0094] In the base of the torso support (1) there is a covered semi-hard surface, as well as the part of the attachment system to the torso support (1) that makes it possible to attach the posterior support (13). The semi-hard surface is divided in two parts and distinguishes the dorsal and lumbar regions, which are subsequently united by an elastomeric band attachment. This flexible joint allows controlled flexion and rotation movements while providing a stable support of the dorsal and lumbar regions, as illustrated in FIG. 11.

[0095] The posterior support (13) is comprised by a set of chained, perforated segments (13). The segments (13) are aligned by their format and they include an elastic medium (14) in their interior, the tension of which is controlled by an engine (15) placed in the seat support (4), located below the seat (3). The force exercised by the engine (15), and respective tension, is sustained in the posterior support (13) and controlled by the surgeon through the pressure from the surgeon's lower limbs on the tensioner pedal (19) located in the base (11). To increase the posterior support (13) tension, press the tensioner pedal (19) with the plus sign; to decrease the tension, press the tensioner pedal (19) with the minus sign. To attach or release the torso support (1) from the posterior support (13), the surgeon will press, using the lower limbs, the attach/release pedal (10) once. The device has a safety switch (9) and a remote control that can be used by a surgeon's assistant if the circumstances prevent the surgeon from making the adjustment. The safety switch (9) must be pressed when activation of any of the features available on the device is intended.

[0096] The posterior support (13) is attached to the seat support (4), the top of the actuators, the engine (15), the shaft (5), the lever (16) and the support actuator (6).

[0097] The device has a base structure (11) around which the weight of the various components that constitute it is distributed. Positioned in the centre of the base (11) is a hydraulic suspension (7) with the objective of relieving the pressure exercised on the actuators. Positioned on top of the hydraulic suspension (7) is the actuator support (6) which, in addition to supporting the linear actuator B (18), is one of the parts of the locking system between the base (11) and the seat support (4). The base (11) is also divided into two areas: the first which relies on the main linear actuator A (17) and the second where the battery (8) will be housed. This set, the hydraulic suspension (7), the linear actuator A (17) and the linear actuator B (18), are installed between the base (11) and the seat support (4) and are protected by a sleeve (20) in the connection between the seat (3) base and the fairing A (21) and fairing B (22). The device also comprises at the base (11), a caster set (12) that allows to move the device in the horizontal plane.

Modes of Use

[0098] The device has two operating modes: the attached mode and the unattached mode.

[0099] In the attached mode, the surgeon is, imperatively, seated on the device and the torso support (1) is attached to the posterior support (13). In this mode, the user has a tensioner pedal (19) on the device's base that allows them to adjust the tension maintained by posterior support (13), relieving the surgeon of the effect of gravity. The attachment of the torso support (1) to the posterior support (13) is provided by a magnetic mechanism on the surface of the torso support (1) and the posterior support (13), activated by the passage of electricity in posterior support's biggest surface (13). Even when attached, the surgeon maintains near normal movements, being allowed moderate flexion, lateral extension and rotation. When the surgery is complete, the surgeon can release himself from the posterior support (13) by activating the safety switch and then pressing the attach/release pedal (10).

[0100] In the detached mode, the torso support (1) attached to the surgeon is not attached to the posterior support (13), allowing the user to move their upper body freely and to stand up from the device. Also in this mode, it is possible to use the posterior support (13) as a support surface, to sit back and rest, in the same way as using a common body support.

[0101] The present embodiment is naturally not in any way restricted to the embodiments described herein and a person of ordinary skill in the art can provide many modification possibilities thereof without departing from the general idea, as defined in the claims. The preferred embodiments described above are of course combinable with one another. The following claims further define preferred embodiments.
