Definitions

  • the disclosure relates to a multi-part adjustable head plate for an operating table according to the preamble of claim 1.
  • a patient is placed on an operating table in a supine, prone or side position. His head can be supported by a head plate attached to the operating table.
  • an anesthetist has to overstretch the head of the patient positioned in a supine position for the purpose of intubation. This can be achieved by folding down the top plate. In order to position the patient's head as gently as possible, the anesthetist should support the head in the neck area with one hand, while he unlocks, angularly and securely fixes the head plate with his free hand.
  • adjustable head plates are required that can be adjusted without vibrations and safely locked. It is also advantageous for positions in prone and side positions if the surgeon or nurse, also referred to below as the user, can support the patient's head while he adjusts the inclination of the head plate with one hand and then fixes it.
  • the document US 6 594 839 B1 describes a conventional multi-part adjustable headstock for an operating table.
  • Adjustable head plates are known from the prior art, which have a joint blockage implemented on one side for the existing joint arrangement of the head plate.
  • manually releasable gas springs are often used with single-jointed head plates, which can be operated either on both sides or centrally from the distal end of the head plate.
  • the use of gas springs compensates for the weight of the top plate, so that no significant manual force is required to pivot the top plate with one hand.
  • such solutions are not known for two-part head plates. Due to the size of the gas springs, head plates are mainly made with gas springs attached to one side, which has a negative impact on the rigidity of the head plates under load.
  • Joint locking mechanisms on both sides are used to increase the stability of multi-part head plates.
  • head plates with four-jointed joints each of which has three rotational joints and a sliding joint with a joint blocking mechanism.
  • two four-bar joints are used, whereby a sliding joint is blocked by a gas spring, while the sliding joint is locked on the opposite side of the head plate by a spindle with a lockable spindle nut.
  • FIG. 1 Such a head plate is shown in the product brochure "OR TABLES - Components and accessories" from Trumpf, No. 1469198, 11/2007 on page 7.
  • This previously known two-hinged head plate 1 ' comprises a first rotary joint 2', which is used to set up and lower a first head plate segment (frame 7 ') relative to the lying surface of an operating table 4', while a second rotary joint 3 'rotates a second head plate segment (carrier plate 8') ) relative to the first head plate segment 7 '.
  • This head plate can be coupled to further segments of an operating table 4 'by means of two single clamps 10' with claws 9 '.
  • a single actuating element in the form of a toggle 5' is provided, which is attached centrally to the outer edge region of the frame 7 '.
  • the joints 2 ', 3' of the two axes of rotation A ', B' have a form-fitting lock that is unlocked by cables (not shown).
  • the active release of the joints can thus be controlled synchronously by actuating a Bowden cable via the toggle 5 '. It is important that bending forces on the Bowden cable core are avoided and that only pure tensile forces are transmitted in order to prevent premature breakage.
  • the Bowden cable of the previously known head plate 1 is spring-supported and enables an active disengagement, but no engagement, of locking elements.
  • Such a configuration of the unlocking mechanism is structurally quite complex and not torsion-proof. In addition, it requires an increased expenditure of force due to the increased friction and leverage, as well as complex assembly and adjustment.
  • Sensitive positioning of the patient's head is therefore only possible to a limited extent during an operation by a single user. To make this possible, it is common for one person to lift the patient's head while another person operates the head plate and brings it into the desired position.
  • the head plate 1 ' which is already known from the prior art, is pivoted, the user runs the risk of jamming his hands between the frame 7', the carrier plate 8 'and a lateral standard rail 6'.
  • the disclosure is therefore based on the object of specifying a multi-part adjustable head plate for fastening to an operating table, with which the setting of the desired position of the head plate segments can be safely and conveniently handled by a single user.
  • the actuating device can be arranged on the headrest segment. Furthermore, starting from the headrest segment, the coupling device can run from the actuating device to the second joint arrangement and, in the unlocked state, assume a position such that the headrest segment can pivot in any angular position with respect to the erecting segment.
  • the coupling device of the head plate can be rotatable about a first pivot point, which can be remote from the actuating device.
  • the position of the coupling device in the unlocked state can be such that the first pivot point lies on the pivot axis of the second joint arrangement.
  • the coupling device In the unlocked state, the coupling device can be aligned radially with respect to the pivot axis of the second joint arrangement.
  • the first unlocking mechanism can comprise a release element, which can be adjustably mounted between the first and the second joint arrangement and, for example, can be connected to the actuating device via the coupling device.
  • the coupling device can be rotatably articulated on the release element via the first pivot point.
  • the coupling device can convert a rotational movement of the actuating device into a translational movement of the release element for unlocking the first joint arrangement.
  • the release element can comprise a first end section associated with the first joint arrangement and a second end section associated with the second joint arrangement.
  • the first end section can be designed as a latching element.
  • the second end section can be connected to the coupling device via a swivel joint.
  • the unlocking device can have a second unlocking mechanism for unlocking the second joint arrangement.
  • the second unlocking mechanism can have complementary latching elements, one of which can be formed on the positioning segment and the other on the actuating device.
  • the latching element formed on the erecting segment can be in the form of a toothed arch, wherein the toothed arch can be arranged coaxially to the axis of rotation.
  • the unlocking device can furthermore have a locking device for locking the position of the actuating device in the locked state in order to prevent inadvertent actuation of the actuating device.
  • the locking device can be rotatably mounted in the actuating device and designed such that it can be switched between two discrete locking positions, namely a first locking position for locking the actuating device and a second locking position for releasing the actuating device.
  • the locking device can interact with a locking spring in order to selectively lock or release the actuating device.
  • the unlocking device can be designed so that both joint arrangements can be unlocked and locked again at the same time.
  • the unlocking device can be designed in such a way that the joint arrangements can be sequentially unlocked and locked again with it.
  • the actuation device can comprise two actuation elements, which can each be arranged on opposite sides of the headrest segment. It can additionally comprise a synchronization element, by means of which a movement of the one actuation element can be transmitted to the other actuation element.
  • the synchronization element of the present head plate can be designed as a switching tube.
  • the locking device can comprise a shift rod arranged coaxially in the shift tube.
  • the head plate according to the disclosure is characterized in that the actuating device for actuating the unlocking device is arranged in a particularly ergonomically favorable position on the second segment, namely the headrest segment.
  • the actuating device for actuating the unlocking device is arranged in a particularly ergonomically favorable position on the second segment, namely the headrest segment.
  • the unlocking mechanism must be implemented in such a way that it enables unlocking of the first joint arrangement without impairing the rotation of the second joint arrangement through its presence.
  • the present head plate thus offers an extremely user-friendly and simple structural design.
  • the unlocking mechanism according to the disclosure is bend-resistant and torsion-proof, structurally simple to implement and very reliable in its actuation.
  • the unlocking mechanism of the present head plate which can be both actively disengaged and actively engaged, is particularly advantageous here.
  • the unlocking mechanism of the present head plate can be designed both frictionally and positively.
  • the unlocking mechanism in such a way that the two top plate segments can be fixed in stages, in particular by means of a form fit.
  • the operating elements can be implemented on both sides of the head plate.
  • the control elements can be operated both with the right hand on one side of the head plate and with the left hand on the other side of the head plate. Accordingly, it is possible to change the operating hand from one side to the other.
  • the headstock operation is user-friendly for both right-handed and left-handed people.
  • Fig. 2 is a side view showing a multi-part head plate 1 according to the disclosure as an exemplary embodiment.
  • the head plate 1 serves to support the head of an operating table 30 (see Fig. 6 ) to support the lying patient during an operation.
  • the head plate 1 comprises a coupling arrangement 2 for coupling to the operating table and two head plate segments 3 and 4.
  • a first head plate segment is designed as a stand segment 3 for raising the head plate 1 and a second head plate segment as a head support segment 4 to support the patient's head.
  • the head plate 1 comprises two joint arrangements 5, 6, each with an axis of rotation A and B (see the two crosses in FIG Fig. 2 ) that are spaced from each other. While the erecting segment 3 is pivotably connected to the coupling arrangement 2 about the axis of rotation A via the first joint arrangement 5, the headrest segment 4 can be pivoted about the axis of rotation B of the second joint arrangement 6 relative to the erecting segment 3.
  • the headrest segment 4 comprises an actuating device 23 which will be described in detail later (see FIG Fig. 6 ), a z. B. padded head support plate 10, two lateral slide rails 8 (in Fig. 2-5 only one is shown) and a mounting rail 9 positioned at the end for attaching accessories, such as, for. B. a control unit, a hose holder for ventilation hoses or an IV stand.
  • the coupling arrangement 2 has two pivot joints 11 for fastening, for example, to each end of a side rail of an operating table 30 (see FIG Fig. 6-10 and 13th ).
  • the pivot joints 11 may each have a right-angled profile that is "L-shaped" in cross-section.
  • the coupling arrangement 2 can comprise two connection sections 7 oriented perpendicularly relative to the patient support surface and two essentially horizontally designed pivot joints 11.
  • Fig. 3-5 show further side views of the head plate 1 according to the disclosure in different angular positions of the head plate segments 3 and 4.
  • the present head plate 1 enables an adjustment of the erect segment in the angular ranges ⁇ 1 and ⁇ 2 via a first degree of freedom of rotation of the erecting segment 3 about the axis of rotation A and, via a second degree of freedom of rotation of the headrest segment 4 around the axis of rotation B, an adjustment of the headrest segment in the angular range ⁇ , in each case can be set in stages.
  • the installation segment 3 can be from an unadjusted starting position of the head plate 1, the height and orientation of which in the coupled state correspond to the height and orientation of the patient support surface ( Fig. 2 ), set up by the angle of inclination ⁇ 1 or lowered by the angle of inclination ⁇ 2 ( Fig. 3 and 4th ).
  • the head plate 1 can be adjusted by the angle of rotation ⁇ by pivoting the head support segment 4 about the axis of rotation B of the second joint arrangement 6 relative to the erecting segment 3.
  • the head plate 1 has the advantage that the patient can be positioned to the side during an operation without any problems.
  • the patient's head - depending on the shoulder width - is positioned a few centimeters above the body support surface on the headrest segment 4 in order to achieve optimal relief for the head and shoulder muscles, which corresponds to a stepped positioning of the head.
  • Fig. 6-8 show the internal structure of the head plate 1 mounted on the operating table 30 Fig. 2-5 . It should be noted that the two top plate segments 3, 4, the joint arrangements 5, 6, and the actuating and locking devices 18, 19, 22 are mirror-symmetrical with respect to a plane running longitudinally through the center of the top plate 1. For the sake of clarity, the Fig. 6-8 only components of a single head plate side are shown.
  • an unlocking device 24 for unlocking the two joint arrangements 5, 6.
  • This comprises an actuating device 23 attached to the headrest segment 4, which is used to actuate the unlocking device 24 by a user, a first unlocking mechanism 25 for unlocking the first joint arrangement 5 and a second unlocking mechanism 31 for unlocking the second joint arrangement 6.
  • the actuating device 23 comprises on each head plate side an actuating element in the form of an actuating sleeve 19 and a switching plate 18 rigidly connected to it, as well as a synchronization element in the form of a switching tube 17, each switching plate 18 together with the actuating sleeve 19 being pivotably mounted about the longitudinal axis C of the switching tube 17 .
  • the switching tube 17 connects the actuation sleeve 19 on the left side of the head plate with an actuation sleeve 19 on the right side of the head plate (see Fig. 11 , 12th ).
  • Each switch plate 18 is located on a side of the actuating sleeve 19 facing the patient's head and is designed in such a way that it has latching elements (not shown) at one end which engage in a receiving element 16 located in the second joint arrangement 6 in the radial direction of this joint arrangement 6 .
  • This locks the rotation of the headrest segment 4 around the B axis ( Fig. 6 ).
  • each receiving element 16 consists of a circular-arc-shaped, toothed area 20 which is each formed on an arm a 1 , a 2 of the erecting segment 3.
  • the latching elements of the switching plate 18 are designed in such a way that they engage in the corresponding latching recesses in the toothed area 20 of the receiving element 16 in a plane perpendicular to the axes of rotation B and C.
  • the two receiving elements 16 with the toothed area or tooth arch 20 and the latching elements of the two switching plates 18 form the second unlocking mechanism 31.
  • the first unlocking mechanism 25 mechanically couples the actuating device 23 to the first joint arrangement 5.
  • it has an elongated release element 13 and an adjustable coupling device 15, with the function of a coupling rod, on both mirror-symmetrical sides of the head plate 1.
  • Each Release element 13 is movably mounted in a guide of arm a 1 , a 2 of erecting segment 3 between the two joint arrangements 5, 6 and is connected to a switching plate 18 of actuating device 23 via coupling device 15.
  • the coupling device 15 is designed as a rigid member, such as a sheet metal or a rod.
  • each coupling device 15 extends from the actuating device 23 to the second joint arrangement 6. Release element 13 is articulated.
  • each coupling device 15 extends obliquely between a switching plate 18 and a release element 13.
  • the first pivot point P is radially offset with respect to the axis of rotation B of the second joint arrangement 6. In particular, the first pivot point P is offset radially inward in the direction of the coupling arrangement 2 with respect to the axis of rotation B.
  • each release element 13 is designed as a fork-shaped tooth piece, which is spring-assisted (H) in engagement with a toothed arch 12 mounted in the first joint arrangement 5. Furthermore, the dental arches 12 are rigidly connected to the coupling arrangement 2. The first joint arrangement 5 is thus locked.
  • Each release element 13 comprises a first end section 13.1 associated with the first joint arrangement 5, and a second end section 13.1 associated with the second joint arrangement 6 associated end section 13.3, as well as a main body 13.2 which extends between the two end sections 13.1, 13.3 and is, for example, angled.
  • the first end section 13.1 forms an engaging head provided with teeth.
  • the coupling devices or tension plates 15 are located in the in Fig. 8 shown unlocked state in an unlocked position. In this position, the first pivot point P lies on the pivot axis B of the second joint arrangement 6.
  • the unlocking device 24 further comprises a locking device 22 for locking the rotation of the actuating device 23 about the axis of rotation C.
  • the locking device 22 is rotatably mounted in the actuating sleeves 19 and is designed so that it can be switched between a lower and an upper discrete locking position. This prevents the joint arrangements 5, 6 from being unintentionally unlocked.
  • the operation of the locking device 22 is in the Fig. 9 and 10 and is described below.
  • the locking device 22 presses a locking spring 26 on each side of the head plate 1 under a hinge plate G, which is part of the headrest segment 4.
  • the locking spring 26 is deformed in the elastic range, similar to a leaf spring. Since the locking spring 26 is non-rotatably connected to a wall of the actuating sleeve 19, the pivoting of the actuating device 23 can be blocked.
  • the locking device 22 has first spring receptacles 22.1. In these, the locking springs 26 sit in the lower latching position, where they under the hinge plate G are jammed. Furthermore, the locking device 22 has second spring receptacles 22.2. In these, the locking springs 26 are in the upper detent position, where they are relaxed.
  • the spring receptacles 22.1 and 22.2 are designed, for example, as concave depressions. In particular, the release receptacle 22.2 is a larger recess than the locking receptacle 22.1
  • one hand grips one of the rod-shaped slide rails 8 at the side.
  • the user can unlock the locking device 22 with one finger and release the rotation of the actuating device 23 about the C-axis ( Fig. 7 ).
  • the user grabs the adjacent actuating sleeve 19 with the same hand and swivels it around the axis of rotation C relative to the positioning segment 3.
  • the resulting rotational movement of the switching plate 18 actuates the second unlocking mechanism 31 and thus unlocks the second joint arrangement 6.
  • this rotational movement is activated by means of the Coupling devices 15 converted into a translational longitudinal movement of the tooth pieces 13 in the erecting segment 3.
  • the coupling devices 15 exposed to the tensile force move from their locking positions to their unlocking positions, so that the connection point of the tooth pieces 13 with the coupling devices 15 (ie the first pivot point P) in the second joint arrangement 6 lies on the pivot axis B, and thus the pivoting of the headrest segment 4 with respect to the erecting segment 3 is possible in any angular position of the first joint arrangement 5.
  • Such a configuration of the present unlocking device 24 enables synchronous unlocking and locking of the two joint arrangements 5, 6.
  • the unlocking device 24 can be designed such that the joint arrangements 5, 6 can be sequentially unlocked and locked again with it.
  • the locking sequence of the two joint arrangements 5, 6 can be influenced by the shape of the adjustable coupling device 15.
  • the coupling device 15 can have an elongated hole at its second end facing the switching plate 18 (at the pivot point Q). At least one end of the elongated hole can form a stop for a connecting element of the switching plate 18 with the coupling device 15, the diameter of the connecting element corresponding to the width of the elongated hole.
  • the chronological sequence of the locking and unlocking of the joint arrangements 5, 6 can be controlled by means of different engagement paths of the form-fitting engagement elements of the two joint arrangements 5, 6.
  • the engagement paths can be determined, for example, by the length of the locking elements of the respective unlocking mechanism 25, 31, with the locking elements only being fully withdrawn from the opposing locking recesses 12, 20 leading to the unlocking of the respective joint arrangement 5 or 6.
  • the unlocking device 24 can be different than in the Figures 2-13 be constructed shown.
  • the actuating device 23 together with the locking device 22 can be positioned on the headrest segment 4 in such a way that it is not pivoted for the purpose of unlocking the two joint arrangements 5, 6, but is shifted either perpendicularly or parallel to the axes of rotation A and B.
  • a translational disengaging and engaging movement of the second unlocking mechanism 31 parallel to the axes of rotation A and B can be combined with a translational disengaging and engaging movement of the first unlocking mechanism 25 in a plane perpendicular to the rotational axes A and B.
  • both unlocking mechanisms 25, 31 can take place parallel to the axes of rotation A and B, for example.
  • the user can set the head plate 1 at an angle with the actuating hand.
  • the mechanism of the two joint arrangements 5, 6 locks automatically. This happens e.g. B. by the force of two return springs F (see Fig. 12 ).
  • the locking of the joint arrangements 5, 6 can for example take place with the aid of a spring (spring H).
  • the joint arrangements 5, 6 can be actively locked by the user by applying pressure. The user can then advantageously move the locking device 22 into the lower latching position with his thumb.
  • Such an unlocking mechanism ensures particularly user-friendly handling of the head plate 1 and excludes unintentional actuation of the unlocking device 24.

  • the locking device 22 comprises a switching rod 27 guided in the connecting tube 17 ( Fig. 13 ).
  • the shift rod 27 can have a round or a polygonal cross-section and thus, for example, be in the form of a tube or hexagon.
  • the shift rod 27 connects the two sides of the locking device 22 to one another. So if the locking device 22 is actuated on one side, the other side follows the movement of the actuated side after, because they over the Shift rod 27 is rotatably coupled to the actuated side.
  • the shift rod 27 is aligned coaxially to the axis of rotation C.
  • the actuating sleeves 19 are rigidly connected to one another via the connecting tube 17, which is coaxial to the axis of rotation C, so that the user can operate the top plate 1 either on one side or on both sides for the purpose of unlocking.
  • the present disclosure provides an unlocking device 24 which can be actuated synchronously from both lateral ends of the headrest segment 4, so that a safe and ergonomic adjustment of the head plate position is possible.
