Uterus OCT catheter and uterus OCT equipment with pull-back function

A uterus OCT equipment with pull-back function, comprising a pull-back device, and a catheter body;

• the catheter body comprises an outer sleeve, an OCT imaging catheter and a Luer connector;
• the outer sleeve is sleeved on the OCT imaging catheter;
• and the Luer connector is used for fixedly connecting the outer sleeve and the OCT imaging catheter;
• the pull-back device comprises a first housing, a driving connector, a fixing sleeve and a catheter fixing tube;
• a first end of the catheter fixing tube is fixed to the driving connector;
• the driving connector is fixedly connected to the fixing sleeve;
• the driving connector and the fixing sleeve are installed inside the first housing;
• and the catheter fixing tube passes through the fixing sleeve and the first housing in sequence, a second end of the catheter fixing tube is fixedly inserted into the Luer connector;
• the driving connector connects a rotary driver and a linear driver, the rotary driver is configured to drive the driving connector to rotate, so the catheter body is driven to rotate around an axis of the catheter body;
• the liner driver is configured to drive the driving connector to move, so the catheter body is driven to reciprocate in an axial direction of the catheter body.
