Description

DESCRIPTION

SUPPORT UNIT DESIGNED FOR SURGEONS

This invention relates to a support unit designed to support the arms of surgeons during a surgery that operate with the technique of laparoscopy.

Today, during the surgeries with the technique of laparoscopy, surgeons need to keep their arms at a certain position, and to move their arms/hands very carefully and elevated while watching the images on the monitor obtained through camera. As keeping the arms at a elevated and static position causes surgeons to become tired in a short while, this, in turn, leads to tiredness and distraction, and this increases risks of the surgical operation. Furthermore, under current practices, surgeon's ability to move the arms/hands elevated on a vertical and horizontal axis or to rotate them on the same level depends on his own control capability and experience, therefore different troubles are likely to occur in case of a slightest slip. Today, a support unit designed to support the arms of surgeons during a surgery that operates with the technique of laparoscopy does not exist. Nor are there auxiliary mechanisms to help the surgeons to move their arms/hands on a vertical and horizontal axis or to rotate.

The product that is the subject matter of invention supports the arms of surgeons during a surgery, prevents tiredness and distraction during a surgical operation, and provides the surgeons with the most convenient operation environment. Providing a surgeon with the most convenient operation environment increases the success rate of a surgical operation. As the product that is the subject matter of invention enables surgeons to move their arms/hands supported in an elevated position and the risk of error is minimised.

The product that is the subject matter of this invention facilitates the surgeon's work during a surgical operation, and enables successful completion of a surgical operation despite too much work load. The product that is the subject matter of invention is shown in the enclosed figures;

The invention is composed of a sitting unit (2) onto the wheeled platform (1), two arm support units (3) and motion activating pedals (4) that control the vertical movement of arm support units (3). Arm support units (3) are, in turn, composed of two-phase telescopic column (5), and an armrest body (8) connected onto the column (5) with the help of a connection cover (polyamide cover) (6) and a fixing plate (7). There is a motion shaft (9) inside the telescopic column (5), and the telescopic column (5) consequently the armrest body (8) moves upwards and downwards on the perpendicular axis triggered by the telescopic column (5). A connection cover (polyamide cover) (6) is equipped onto telescopic cover (5), and a fixing plate (7) is placed on this cover. The fixing plate

(7) is equipped with a slide casing (slide wagon) (10). The slide (1 1), which is placed under the armrest body (8) passes through the slide casing (10), connecting the armrest body (8) and the telescopic cover (5). As the slide (11) is capable of moving back and forth inside the slide casing (10), the armrest body

(8) is capable of moving back and forth on the telescopic cover (5). There is a gradual motion layer (12) that has a graded structure on the lower side of the armrest body (8). The back and forth motion positioning pin (13) is, however, on the side of the slide casing (10). The gradual motion layer ( 2) both slows down and cascades the back and forth motion velocity of the armrest body (8) thanks to back and forth motion positioning pin ( 3). This enables the surgeon to control back and forth motion of the arms during a surgery. There is a bearing case (14) inside the fixing plate (7). The bearing spindle (15) that passes through the connection cover (6) is connected to the bearing (16) placed in the case. The fixing plate (7) rotates around itself with the help of this bearing (16). The armrest body (8), which is connected to the fixing plate (7) rotates around itself as the fixing plate (7) is capable of rotating. A limiting case (17) has been graven on the upper surface of the connection cover so that the rotating velocity of the armrest body (8) is limited and cascaded with a motion limiting plate (18) has been placed inside the case. The motion limiting plate (18) has an graded surface structure, and is fixed into the limiting case thanks to bolts that pass the fixing holes (19) on the edges thereof. There is an rotation angle limiting pin (20) on the lower surface of the fixing plate (7). While the fixing plate (7) moves to rotate to the left and to the right, the rotation angle limiting pin (20) moves with an angle on the motion limiting plate (18), ensuring that the motion is slow and cascaded, and the rotation ends on the edges of the limiting case. In this way, the armrest body (8), which is connected to the fixing plate (7) limits the rotating motion during the surgery, and facilitates the surgical operation for the surgeon.

The invention vertical movement is controlled through the motion shafts (9) that have been placed on the left and right hand sides as indicated above, inside the telescopic column (5) on the armrest support units (3), activated with the help of the pedals (4). The pedals (4) have been positioned to correspond the surgeon's feet on the platform (1). The pedal (4) is composed of a cantilevered foot plate (21) that is articulated from below, with upward motion switch (22) and downward motion switch (23). When the surgeon puts his feet onto the foot plate (21) and applies pressure on the rear of it (the heel), the upper toe of his feet contacts the upward motion switch (22) of the motion pedal (4), thus the telescopic column (5) and the armrest body (8) moves upwards through the motion shaft (9) inside the telescopic column (5) equipped on the relevant armrest support units (3). When the surgeon applies pressure onto front (toe) of the foot plate (21), the foot plate (21) contacts the downward motion part (23) of the motion pedal (4), and the motion shaft (9) inside the telescopic column (5) within the relevant arm support units (3), and consequently the telescopic column (5) and the armrest body (8) move downwards.

The armrest cushion (24) where the surgeon places his arm on the armrest body (8) is connected to the arm connection plate (25), and can be put on and removed with the help of the arm connection plate (25). Armrest cushion (24) can be replaced in case of hygiene and in case of wear and tear due to usage in the course of time.

The sitting unit (2) available on the invention is composed of a sitting body column (26), and the sitting body (27), which is connected to the sitting body column (26). The motion of the sitting body column (26) on the vertical axis is enabled by gas springs (28) inside of it, and is controlled by the control handle (29) that extends outwards. A slide canal (30) has been opened on the upper side of the sitting body column (26) inside the sitting unit (2); and the slide ( 1) that is on the lower side of the sitting body (27) passes to the slide canal (30), enabling interconnection of the sitting body (27) and sitting body column (26) . The slide (11) is capable of moving back and forth inside the slide canal (30), therefore the sitting body (27) is capable of moving back and forth. As the surgeon can adjust his position on a vertical and perpendicular axis of the sitting body (27) before and during the surgery, it is ensured that the surgeon is seated in the best position at the sitting body (27) during the surgery. In case of surgical operations performed by the technique of laparoscopy ( or similar), the invention enables the surgeon to adjust the most convenient working position, enabling him to move freely during the surgical operation, as this will affect the success rate of the surgical operation positively, the invention is not only facilitating for the surgeon but also advantageous for the patients.
