Embodiment Construction

[0045] In the following description, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. The figures here are not necessarily drawn to scale, but merely show corresponding features schematically.

[0046] It should be noted here that the features and components described below can be combined with one another, regardless of whether they have been described in connection with a single embodiment or not. The combination of features in the various embodiments is only used to illustrate the basic structure and working method of the claimed device.

[0047] like figure 1As shown in , an operating table 1 includes a patient support surface 2 , a support column 3 and a foot 4 . For performing orthopedic surgery, a telescopic beam 10 can be used, by means of which the leg of the patient P can be fixed in a desired position. To this end, on the beam portion 12 of the telescopic beam 10 a movable strut 14 can be mounted, whic...

Abstract

Self-locking spindle traction mechanism (16) for use in surgical interventions, with a longitudinal axis (L), comprising: - an operating end (11); - a connecting end for connecting a surgical accessory; - a threaded spindle drive (17) with a) a spindle (32) having an external thread; and b) a spindle nut (31), which is seated on the spindle (32) and has an internal thread which engages with the external thread; - a slide (22), which can be moved along the longitudinal axis by a relative rotation between the spindle and the spindle nut; - a driving device (20), which is located at the operatingand (11) and is intended for rotationally driving the threaded spindle drive; and - a gear mechanism (30), which is arranged between the driving device (20) and the threaded spindle drive (17), wherein the gear mechanism is designed for stepping up the speed of the rotational movement of the driving device (20) and delivering it to the threaded spindle drive (17).

Description

technical field [0001] The present disclosure relates to a pull screw assembly that may be used on an operating table, for example, in a telescoping beam. Background technique [0002] Such telescopic beams generally comprise a beam part on which a support for the patient's foot is movably mounted by means of movable struts or the like with a pull-screw assembly connected in between. After securing the strut, it may be desirable for some surgical applications to move the support and the patient's foot further in the direction of the longitudinal axis of the patient's leg by means of the pull screw assembly, for example to pull the patient's hip joint. Usually, this linear adjustment movement is realized by pulling the lead screw drive of the lead screw assembly, and the user can operate the lead screw drive through a hand crank. At this time, a relatively high axial force acts on the pulling screw assembly, and it is important to maintain the once-adjusted axial position of...
