Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an orthopedic table, and more particularly to an orthopedic table having a movable upper body support and a sacral support.

The performance of modern orthopedic procedures requires a support or table that meets several needs for the patient on whom the procedure is to be performed. This table must allow hospital personnel to transfer the patient from the stretcher to the table in a manner that requires as little physical stress as possible on the patient's body. The table should facilitate quick, convenient, and accurate placement of the patient's body onto the table. The table must be such that hospital personnel can reposition the patient's body relative to the table with as little physical stress as possible on the patient's body. The table must allow the plastic surgeon unrestricted access to the parts of the patient's body on which the plastic surgery procedure is being performed. The table allows the image magnification device to be placed closest to all parts of the patient's body, allowing the orthopedic surgeon to examine the part of the patient's body on which the procedure is performed, regardless of the type of procedure performed. It must be something that does that.

A conventional orthopedic table consists of a support for the patient's upper body, a base for supporting the upper body support at a distance from the floor, and an abductor extending from the base for supporting and positioning the patient's legs. Has a bar. Typically, the abduction bar is rotatably mounted on the base and has foot supports that are fastened to the bar. The foot support can be moved along the abduction bar to accommodate patients of different sizes.
The upper body support of a conventional orthopedic table is fixed to the base and cannot be moved relative to the base. Additionally, the base of a conventional orthopedic table typically includes an upper body support housing a control device for tilting the upper body support or a portion thereof to facilitate performance of a given orthopedic procedure. It has a lower housing.

Due to the fixed position of the upper body support relative to the part of the table base in contact with the floor and the control housing and the proximity of the housing to the upper body support, several problems arise. The image magnifying device must be placed close to the body part to be examined - usually both above and below, and the control housing and base of a conventional table accommodate such a device in the area below the upper body support. The area of the patient's body that can be examined with the image magnification device is not restricted because it prevents the placement of the image. Further, the control housing and base often prevent the orthopedic surgeon from assuming the most favorable position relative to the patient's body to perform the orthopedic procedure. Often, the control housing and base prevent the operator from positioning the stretcher supporting the patient adjacent to the upper body support, thus allowing the operator to manipulate the patient through distance and risk of trauma to the patient's body. I have to move it. Additionally, due to the fixed position of the end of the abductor bar attached to the base relative to the upper body support, depending on the orthopedic procedure being performed, the upper body support or the abductor bar may obstruct the orthopedic surgeon during performance of the procedure. Also, since the position of the abductor bar relative to the upper body support cannot be changed, positioning of the patient relative to the abductor bar for bilateral procedures must be accomplished by moving the patient in the upper body support. , which may cause trauma to the patient's body.

Therefore, there is a need for an orthopedic table that provides greater access to the area of the patient's body on which orthopedic procedures are being performed than is the case with conventional orthopedic tables. Additionally, there is a need for an orthopedic table that minimizes the risk of trauma to the patient's body when the patient is transferred from the stretcher to the table and during orthopedic procedures.

The present invention provides an improved orthopedic table for supporting a patient in a desired position. This table consists of a support for the patient's upper body, a base that supports the upper body support at a certain distance from the floor, a member that is attached to the base and supports the patient's legs, and a member that supports the patient's legs supported by the base. It consists of a model that has a support part for the sacrum. A feature of the invention is that the sacral support is adapted to move relative to the upper body support in a direction parallel to the plane of the upper body support away from the base or the point of attachment of the leg support to the base. That's true. In a preferred embodiment of the invention, the sacral support is rigidly attached to or integrally formed with the upper body support.

The upper body support and the sacral support can thus be moved away from the table base and the leg supports, thus solving the problems experienced in the use of conventional orthopedic tables mentioned above. . Since the upper body support can be positioned relative to the table base, the present invention provides
To provide an orthopedic table that can be included within a control housing device for limiting tilting of an upper body support comprising a design that is less limited by size requirements than by functional requirements. . Additionally, the present invention provides an orthopedic table that does not require hospital personnel to move the patient's upper body relative to the upper body support when the patient's upper body must be positioned horizontally relative to the lower body. provide.

Preferred embodiments will be described in detail below with reference to the accompanying drawings.

0 through bearings 110 and 104, respectively, to move upper body support 36 relative to table 10. The upper body support 36 can be positioned in three positions: a central position where the longitudinal axis of the upper body support 36 is substantially common to the centerline 122 of the table 10; 2 off center placed to the side or the other side
It can be fixed in one of two positions.
The upper body support 36 is fixed in a central position when the stop pin 116 is placed within the opening 120 of the lock bar 74. The upper body support 36 is fixed in an off-center position when the stop pin 116 is placed in either opening 98. Spring 84 is a compression spring and locks bar 74 against pin 116.
Depending on the position of the lower surface 124 of the lock bar 74,
The lock bar 74 is biased toward a position in which the stop pin 116 contacts the stop pin 116 or the stop pin 116 is disposed within the opening 98 or 120.

If the lock bar 74 is positioned such that the pin 116 is located in the opening 98 or 120, the relative position of the body support 36 will change only when one actuator 46 is pulled toward the circumference of the body support 36. can be changed. Such movement of the actuator 46 causes the member 54 to pull the sliding member 60 in the direction of movement of the actuator 46, causing the pin 90 to engage the cam slot 94.
by applying a force to lift the locking bar 74 toward the underside 48 of the upper body support 36 and removing the pin 116 from within the opening 98 or 120. Then, the upper body support section 36 is moved horizontally to a desired position. To once again secure the upper body support 36, the stop pin 116 is aligned with the aperture 98 or 120, thereby causing the spring 84 to engage the lower surface 48 of the upper body support 36.
Push the lock bar 74 away from the opening 98.
Alternatively, the upper body support 36 must be moved horizontally until the stop pin 116 can be placed within the stop pin 120. At that point, the upper body support 36 cannot be moved further until the actuating portion 46 is moved toward the circumference of the upper body support 36 .
