Steel wire separation fixator for gastrointestinal endoscope maintenance and application method thereof

Abstract

The invention discloses a steel wire separation fixator for gastrointestinal endoscope maintenance and an application method thereof. The fixator comprises an inner core, a barrier unit, a support unit and a limiting unit; four corresponding placing tanks are formed in the peripheral surface of the inner core; a mounting groove is formed in the middle part of the left end surface of the inner core; four corresponding first clamping grooves are formed in the edge part of the left end surface of the inner core; the first clamping grooves communicate with the placing tanks and the mounting groove; steel wires are fixed through the first clamping grooves; the barrier unit is mounted in the mounting groove; the barrier unit is used for obstructing the support unit; the support unit is mounted at the left end of the inner core; the steel wires are ejected up through the support unit; the limiting unit comprises slide grooves, slide blocks and connecting rings; and four corresponding slide grooves are formed in the right end of the peripheral surface of the inner core. The fixator can guarantee no knotting condition of four steel wires after pullout of the inner core, and can maintain positioning.

Description

technical field [0001] The invention relates to the technical field of medical maintenance, in particular to a wire separation fixer for gastroenteroscope maintenance and a method for using the same. Background technique [0002] Gastroenteroscope is a flexible tube slightly thicker than a ballpoint pen (about 100cm long), with a miniature camera installed at the front end, which can directly transmit the images of the upper gastrointestinal tract, esophagus, stomach, and duodenum to the TV screen. The endoscope needs to be repaired during long-term use. After the repair is completed, the inner core with four steel wires needs to be inserted into the gastroenteroscope. The existing technology generally adopts a long and thin stainless steel with four grooves. , inserted from one end, the four steel wires will naturally enter the groove and come out at the other end, but because there is only simple slender stainless steel, it is difficult to keep the four steel wires in posi...

Problems solved by technology

[0002] Gastroenteroscope is a flexible tube slightly thicker than a ballpoint pen (about 100cm long), with a miniature camera installed at the front end, which can directly transmit the images of the upper gastrointestinal tract, esophagus, stomach, and duodenum to the TV screen. The endoscope needs to be repaired during long-term use. After the repair is completed, the inner core with four steel wires needs to be inserted into the gastroenteroscope. The existing technology generally adopts a long and thin stainless steel with four grooves. , inserted from one end, the four steel wires will naturally enter the groove and come out at the other end, but because there is only simple slender stainless steel, it is difficult to keep the four steel wires in position after the slender stainless steel is pulled out, and some Sometimes the four steel wires will be knotted. After the above situation occurs, the steel wires need to be pulled out again, which greatly wastes time.
