Telescopic support rod

An indexed telescoping support rod, comprising:

• a nesting tubular member comprising a longitudinal axis, a base, a top, and a plurality of parallel recess pairs opening to an internal cylindrical volume, the recess pairs disposed in an anterior column and a posterior column;
• a nested tubular member being frictionally slidably coupled to the nesting tubular member, the nested tubular member having a longitudinal axis, a base, and a top;
• a pawl operably coupled to the base of the nested tubular member, the pawl comprising a pair of outwardly biased, diametrically opposed arms, each arm comprising a ventral surface, a dorsal surface, a proximal end, a distal end, and a shelf formed in the dorsal surface thereof, wherein each recess pair is configured to receive and engage the distal end of each of the pawl arms and wherein the shelf is configured to support the base of the nested tubular member;
• a detent mechanism disposed apically on the nesting member;
• and
• an apically beveled circumferential groove disposed toward the base of the nested member, wherein the detent mechanism is configured to be received in and engage the apically beveled circumferential groove, thereby preventing the apical movement of the nested tubular member beyond a predetermined axial position of the apically beveled circumferential groove.

A method of selectibly modulating the length of an indexed telescoping support rod, the support rod comprising:

• (i) a nesting tubular member comprising a longitudinal axis, a base, a top, and a plurality of parallel recess pairs opening to an internal cylindrical volume, the recess pairs disposed in an anterior column and a posterior column;
• (ii) a nested tubular member being frictionally slidably coupled to the nesting tubular member, the nested tubular member having a longitudinal axis, a base, and a top;
• and
• (iii) a pawl operably coupled to the base of the nested tubular member, the pawl comprising a pair of outwardly biased, diametrically opposed arms, each arm comprising a ventral surface, a dorsal surface, a proximal end, a distal end, and a shelf formed in the dorsal surface thereof, wherein each recess pair is configured to receive and engage the distal end of each of the pawl arms and wherein the shelf is configured to support the base of the nested tubular member;
• wherein the distal end of each of the pawl arms is engaged in the recesses comprising:
• a. axially translating the nested tubular member relative to the nesting tubular member axially toward the apical end of the nesting member until the distal end of each of the pawl arms disengage from the anterior and posterior pair of recesses in the nesting tubular member;
• b. upon disengagement of the distal end of the pawl arms from the anterior and posterior pair of recesses in the nesting tubular member, radially translating the nested tubular member relative to the nesting tubular member between about 0.8 rad. and about 2.4 rad.;
• c. axially translating the nested tubular member relative to the nesting tubular member toward the apical end to lengthen the telescopic support rod, or toward the base to shorten the telescopic support rod to achieve a selectable length;
• and
• d. radially translating the nested tubular member relative to the nesting tubular member until the distal end of each of the pawl arms are engaged in the anterior and posterior pair of recesses in the nesting tubular member corresponding to the selectably modulated length.
