Additional features, which alone or in combination with any other feature(s), including those listed above and those listed in the claims, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the invention as presently perceived.
The detailed description particularly refers to the accompanying figures in which:
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.
In performance of various procedures, whether surgical, treatment, diagnosis, or otherwise, providing desirable access to a patient's body areas can be beneficial. For example, in performing surgical procedures, providing surgical access to surgical sites on a patient's body can promote favorable surgical conditions and can increase the opportunity for successful results. Patient support devices can assist in suitably positioning the patient's body in various manners to provide a surgical team with preferred and/or appropriate access to particular surgical sites.
Patient support devices can include patient support tops which are supported above the floor by support structures. Such support structures can provide enhanced maneuverability to assist in positioning the patient's body by permitting selective movement of the patient support top. The safety concerns related to positioning a patient's body can impose complex and/or multi-step processes onto the positioning devices. Ease of operating the positioning devices can reduce user strain, reduce time in positioning, and reduce impact to the patient in obtaining various patient body positions.

The tower bases 12 each illustratively include a connection rod 16 connected with the support top 14 by a connection assembly 18. Non-limiting examples of acceptable connection bars and connection (coupler) assemblies are disclosed in U.S. Patent Application Publication No. 2013/0269710 to Hight et al., (for example, shaft 112 may form the connection rod 16), the contents of which are hereby incorporated by reference in their entirety, and at least including the descriptions and figures related to yoke brackets and motion couplers and related features disclosed therein. In some embodiments, the patient support top 14 may be connected with the connection rod 16 in any suitable manner. In the illustrative embodiment, the connection rods 16 are illustratively arranged for controlled rotation about the axis 15 to provide rotation to the support top 14. Although generally shown as horizontal, the axis 15 may be selectively inclined by operation of the elevator towers and/or the connection assemblies 18 to adjust the height of their respective connection with the patient support top 14.
The patient support top 14 is illustratively embodied as a flat platform including a rail frame 20 having a deck that is covered with support padding 22. The support top 14 is embodied as adapted for support of a patient in the supine position, including padding 22 arranged accordingly, but in some embodiments, may be adapted for support of a patient in any suitable position. The patient support top 14 is selectively connected with the connection rod 16 of each tower base 12 via the respective connection assembly 18 and is positionable for selective angling and rotation about axis 15.
In the illustrative embodiment as shown in
In the illustrative embodiment, the longitudinal angle can also be referred to as the Trendelenburg angle, which can include negative Trendelenburg angle. One suitable example of a patient support having adjustable Trendelenburg angle is disclosed within U.S. Provisional Patent Application No. 62/636,563, the contents of which are hereby incorporated by reference, in their entirety, and including at least those portions related to adjustable patient support. In some embodiments, the patient supports of the present disclosure may include additional adjustments features including but without limitation, adjustment of flip rotation, height, tilt, level, leg drop, any other feature disclosed within U.S. Provisional Patent Application No. 62/636,563, and/or any other suitable adjustment, for example but without limitation, the patient support 10 of the present disclosure may be arranged for flip rotation about its axis 15, as disclosed within U.S. Provisional Patent Application No. 62/636,563.

The longitudinal angle of the support top 14 about the defined pivot point 25e is adjustable within the range of angles φe. The lateral location of the pivot point 25e along the support top 14 is also indicated on the support top 14 by 27e as discussed in additional detail below. By arranging the pivot point 25 to be spaced apart from the support top 14, a particular location of the patient's body can be closely targeted as the pivot point assignment location, for example, a point on the occupying patient's body desired for surgical access which itself is spaced apart from the surface 28 of the support top 14. During adjustment of the longitudinal angle of the support top 14, the portion of the patient's body at the defined pivot point 25e can be maintained mostly stationary to assist appropriate access to the point of the patient's body. In some embodiments, the longitudinal position of the support top 13 can be shifted, for example, by articulation and/or translation of the connection assemblies 18 and/or rods 16, to arc about the pivot point 25e, more particularly, the rods 16 may be telescopic to allow horizontal shifting of the support top 14 to provide additional focusing on defined pivot point locations off-set from the support top 14.
As shown in
The lateral location of the pivot point 25f along the support top 14 is indicated on the support top 14 by 27f Accordingly, the lateral and vertical location of the pivot point can be assigned as desired by the user to accommodate customized surgical access during longitudinal angle adjustment. In the illustrative embodiment, the distance d defining the spacing of the defined pivot point 25 above the surface 28 can be predetermined (and adjusted) by the user. The indications 27 on the support top 14 can indicate the point of interaction for the user to engage as an input to assign the location of the pivot point 25 and/or as an indication of the current location of the pivot point 25 as discussed in additional detail herein.

The controller 44 is arranged in communication with the support top 14. The controller 44 communicates with the input 32 to receive user input of the desired location for the pivot point 25 and communicates with the indicator 30 to illuminate the portion of the indicator corresponding with the assigned pivot point location. Other portions 52 of the patient support 10 for adjusting the position of the support top 14 are represented as part of the support top 14 but may include features outside the support top 14, for example but without limitation, those sensors and actuators of the tower bases 12.
As shown in
Many complex surgical procedures, such as spine procedures, are performed on two-column table. Two-column tables may allow for the caregivers to manipulate the height of the patient platform, the tilt angle (left and right), and the Trendelenburg angle. Some tables may allow all three dimensions to be adjusted both before and during a procedure.
Spinal surgery can take place at any level along the spine, often in one or more major areas including the cervical, thoracic, and lumbar regions. As such, the surgical site of the patient varies dramatically with respect to the length of the table. For example, the surgical site for cervical procedures is closer to the head end of the table, whereas the surgical site for lumbar procedures is closer to the middle of the table. Most often, this variance in surgical site with respect to the table is of little or no consequence. However, if a surgeon is to perform an intra-operative Trendelenburg angle adjustment and the surgical site is not in the middle of the table, the Trendelenburg adjustment can result in an undesirable change in height of the surgical site. This is because the pivot point for trending the patient platform is fixed in the middle of the table (between the head and foot end). Consequently, a member of the clinical staff needs to perform a secondary height adjustment of the table to return the surgical site to the same height or a similarly desirable height with respect to the surgeon. Providing flexibility in assigning the pivot point for Trendelenburg angle adjustment can provide the surgeon the ability to intraoperatively set the pivot point for trending the patient, obviating the need for a secondary height adjustment. An indicator may be included to communicate the current location of the pivot point.
The present disclosure includes devices, systems, and method for patient platforms—for example, supine, prone, or lateral support tops—that include a soft potentiometer and a strip of individually addressable LEDs. The LEDs may run in parallel with the potentiometer in a channel that extending the length of the side rail of the patient platform. The profile of the channel can allow for predicate pads and top accessories to be attached the side rail. Additionally, the channel can allow the soft potentiometer to be activated by a finger press and the LEDs to be seen by the user. In some embodiments, a battery may provide power for the disclosed functions and may reside in the support top, and/or the top may connect to the power supply of the table, and/or may connect to a wall outlet and/or other power source. Communication between the support top and patient support may be wireless (e.g., Wifi, Bluetooth, nfc, etc.) and/or through a wired connection.
The devices, system, and methods within the present disclosure may include: 1) The user pressing and holding on the soft potentiometer located on the side rail of the patient platform for pre-defined amount of time (e.g., 2 seconds); 2) The new pivot point position being captured and relayed to the table via software and/or hardware; 3) The pivot point position being indicated to the user by an illuminated region of LEDs on the rail. Features of the present disclosure allow these elements to take place through a sterile drape so that the surgeon (and/or other caregiver) doesn't have to break the sterile field, i.e. the soft potentiometer can be activated when draped and the LEDs are bright enough to shine through the drape. The devices, systems, and methods of the present disclosure can provide the surgeon greater control over the position of the patient. Specifically, it can allow the surgeon to retain an optimal, ergonomic, surgical site position irrespective of Trendelenburg adjustments.
Although certain illustrative embodiments have been described in detail above, variations and modifications exist within the scope and spirit of this disclosure as described and as defined in the following claims.
The present application claims the benefit, under 35 U.S.C. § 119(e), of U.S. Provisional Application No. 62/724,728, filed Aug. 30, 2018, which is hereby incorporated by reference herein in its entirety.
