Trans-oral surgery device comprising a blade with a distal scaffold and a support adjustable through tendons

A method of performing trans-oral laser surgery, comprising:

• providing a trans-oral surgery device comprising:
• a scaffold insertable into a vicinity of a larynx or hypopharynx of a subject;
• a support arranged for holding a flexible optical fiber for delivering light to the subject, wherein the support is housed within the scaffold;
• a plurality of tendons connected to the support and slidably anchoring the support to the scaffold, whereby the tendons are adjustable to move the support relative to the scaffold, and
• wherein each of the tendons connects the support to the scaffold along a different direction respective to each of the other tendons, such that each of the tendons is adjustable to move the support in a different direction relative to the scaffold respective to each of the other tendons, and
• wherein the plurality of the tendons slidably anchoring the support to the scaffold comprises a first set of the tendons connected to the support toward a front end of the support, and a second set of the tendons connected to the support toward a rear end of the support, and wherein the first set of the tendons and the second set of the tendons directly contact the scaffold;
• and
• a blade having a front end and a rear end, wherein the scaffold is provided at the front end of the blade, and the blade is non-straight;
• inserting the scaffold into the subject using the blade to hold and support the scaffold;
• and
• operating the tendons to position and orient the support relative to the scaffold, to direct laser light emitted from an optical fiber held by the support to perform trans-oral laser surgery on the hypopharynx or larynx tissues of the subject.
