Detachment and replacement method for a laparoscopic tube for an oximetry probe

A method comprising:

• forming housing comprising a first structure and a second structure, wherein providing the housing is reusable and is configured for use with a plurality of first laparoscopic element elements that is disposable;
• forming a first opening at an end of the first structure, wherein the first opening comprises a through hole;
• positioning in the first structure a processor, a memory coupled to the processor, and a light engine coupled to the processor, coupling the second structure to the first structure by coupling a second opening of the second structure to the first opening of the first structure, wherein the second opening comprises a through hole through which at least a portion of the first structure is inserted through;
• coupling a first optical conductor through the through holes of the first and second openings to the light engine and a first optical interface;
• forming laparoscopic element, removably couplable to the second structure of the housing, comprising a third structure, a fourth structure, and a second optical conductor;
• forming a third opening in the third structure at a first end of the first laparoscopic element;
• forming a fourth opening in the third structure oppositely located from the third opening;
• coupling an interior surface of the third structure over an outside surface of the second structure through the third opening forming a mated connection coupling when the laparoscopic element is removably coupled to the second structure of the housing;
• positioning a sensor head at a second end of the fourth structure that is oppositely located from a first end of the fourth structure;
• optically coupling the second optical conductor to the first optical conductor in an interior space of the third structure when the laparoscopic element is removably coupled to the second structure of the housing;
• coupling the second optical conductor through an interior space of the fourth structure to the sensor head;
• positioning a printed circuit board (PCB) in the second structure;
• coupling a photodetector to a surface of the PCB and to the processor via the PCB;
• optically coupling a third optical conductor to the photodetector in the second structure;
• positioning a fourth optical conductor in the laparoscopic element;
• coupling the fourth optical conductor through the laparoscopic element to the sensor second head;
• and coupling the fourth optical conductor though the laparoscopic element to third optical conductor when the housing and laparoscopic element are removably coupled, wherein at least a portion of the first structure is inserted through the through hole of the second opening of the second structure.
