A telescopic transmission assembly includes first and second stage rods, and first and second stage casings. The second stage rod is of a hollow structure having inner and outer surfaces and a through hole, the outer surface being provided with external threads, and the inner surface being devoid of threads. The first stage rod is disposed in the through hole to drive the second stage rod to rotate synchronously. The first and second stage rods are telescopically expandable or contractible relative to each other along an axial direction. The second stage casing sleeves over the first stage casing. The first and second stage casings have respectively first and second transmission nuts. The second and first stage rods are in a screw-thread fit with the first and second transmission nuts, respectively. The second stage rod is positioned with the first transmission nut in the axial direction in a rotatable manner.

A cable adjustment mechanism for connecting a cable assembly comprising a cable to a bracket, the mechanism comprising: a connecting bushing having a bracket connector for attaching to the bracket, a first body interior for receiving the cable there though, and a cable connector for attaching to the a mechanism body of the cable assembly; the mechanism body having a second body interior for receiving the cable there though, a first end, and a second end for receiving the connecting bushing, the first end opposed to the second end, the second body interior defining an adjustment axis; a spacing member having one end for coupling to a cable body of the cable assembly and another end for coupling with the mechanism body at the first end, the another end opposed to the one end, the spacing member having a third body interior for receiving the cable there through; and a lock for retaining a selected relative position on the mechanism body along the adjustment axis in order to retain a resultant separation distance between the connecting bushing and the cable body; wherein the selected relative position is determined by adjusting a position of the coupling of the one end with respect to the first end along the adjustment axis prior to locking the selected relative position by the lock.

A Bowden cable coupling for releasably coupling a first Bowden cable to a second Bowden cable is configured and operable to transmit mechanical forces from an activation element to a functional element. The Bowden cable coupling has a first coupling unit which is connected to the first Bowden cable, a second coupling unit which is connected to the second Bowden cable, and a coupling sleeve for connecting the first coupling unit and the second coupling unit together, wherein the first coupling unit and the coupling sleeve are releasably connected to one another by way of a bayonet closure.

An anti-buckling device for an interventional device assembly includes a telescoping tube having a proximal end and a distal end, the proximal end of the telescoping tube being coupled to a first hub of an interventional device assembly, and a distal retainer coupled to the distal end of the telescoping tube, the distal retainer being configured to releasably couple to a distal hub attachment at a distal end of the first hub in a first configuration and releasably couple to a second hub of the interventional device assembly positioned distal to the first hub in a second configuration.

An anti-buckling device for an interventional device assembly includes a telescoping tube having a plurality of concentric telescopically axially extendable and collapsible tube segments, the plurality of tube segments including an outermost tube segment and one or more inner tube segments. Each of the one or more inner tube segments comprises a first tube section having a first outer diameter and a second tube section having a second outer diameter.

An interventional device assembly includes a first hub positioned along a drive table, the first hub having a proximal end and a distal end, an interventional device coupled to the first hub and extending distally therefrom, and a telescoping tube having a proximal end and a distal end. The proximal end of the telescoping tube is secured within an interior of the first hub between the proximal end of the first hub and the distal end of the first hub. The distal end of the telescoping tube is configured to secure to a second hub positioned along the drive table or a distal attachment coupled to the drive table. At least a portion of the interventional device extends through the telescoping tube.

An anti-buckling device for an interventional device assembly, includes a telescoping tube having a plurality of concentric telescopically axially extendable and collapsible tube segments each with a proximal end and a distal end. One or more of the plurality of tube segments includes an inner diameter reducing feature configured to reduce an unsupported free length of an interventional device of the interventional device assembly when the interventional device extends through the telescoping tube, the inner diameter reducing feature attached to the distal end of its associated tube segment having a through hole configured to receive the interventional device therethrough.

An anti-buckling device for an interventional device assembly includes a telescoping tube having a plurality of concentric telescopically axially extendable and collapsible tube segments each having a proximal end and a distal end, the plurality of tube segments having an innermost tube segment and one or more outer tube segments, the innermost tube segment being configured to couple to a hub of an interventional device assembly, the telescoping tube being configured to extend distally from the hub. Each of the one or more outer tube segments is coupled to a cap at its proximal end, the cap having a through hole configured to receive an interventional device of the interventional device assembly therethrough and an outer diameter greater than an outer diameter of the outer tube segment to which the cap is coupled.

An assembly for adjusting a cable that includes a locking sleeve and an adapter that is connected to the cable. The adapter includes male and female-threaded portions that are coupled together. The locking sleeve is configured to be displaced between engagement and disengagement positions. When in the engagement position, securing devices of the male and female-threaded portions engage inner sections of the locking sleeve in a manner that prevents the male and female-threaded portions from being rotated relative to each other, thereby preventing a change in the length of the adapter so as to prevent an adjustment of the cable. When the cable is to be adjusted, the locking sleeve is displaced to disengagement position such that the securing device of either the male or female-threaded portion is disengaged from the locking sleeve, thereby allowing rotation of the male or female-threaded portions relative to each other.
