TROUBLESHOOTING GUIDE TruClear™ System
TruClear™ Hysteroscopic Tissue Removal System (control unit, footswitch, handpiece) and TruClear™ shavers Issue
Suggestion/Solution
Mode does not change via oscillate lock button
· Check handpiece cable is fully inserted into TruClear control unit · Check footswitch cable is connected properly · Make sure oscillate lock button on footswitch is being depressed adequately
Window lock – internal sheath jumps or rotates too fast
· Reseat the shaver into the handpiece · Remove handpiece cable from console. Turn off TruClear control unit.
™
™
Unplug from the wall and plug it back in. Turn unit on. Insert handpiece into control unit.
· If window lock is performed outside of patient, consider: Window lock – unable to see lines on the shaver
– Moving instrument away from the OR spot lights – Inserting shaver into scope and watching tip of shaver on video monitor to observe internal sheath rotation
· Consider performing window lock inside the uterine cavity No specimen in tissue trap at end of case
· Confirm handpiece suction is in the ON position · Make sure white handpiece tubing is connected to tissue trap · Check if tissue chunks visible in the suction tubing during tissue removal · Flush handpiece suction channel to ensure tissue flow · Ensure reprocessing is adequately brushing and cleaning channels
TruClear™ Elite Hysteroscopes Issue
Suggestion/Solution
Fluid leaking from scope
· Ensure white disposable seal (Reference #72205051) is on working channel · Check that the appropriate sheath o-ring is present · Ensure that all stopcock valves are tight
TruClear™ Operative 5C Hysteroscope
Fluid leaking from scope
· Ensure blue rubber seal (Reference #7205561) is on working channel · Check that the appropriate sheath o-ring is present inside the hysteroscope · Ensure that all stopcock valves are tight · Confirm that sheath is secure on scope
HysteroLux™ Fluid Management System Issue
Suggestion/Solution
Poor uterine distention
· Check inflow tubing for obstructions and/or kinks · Reposition hysteroscope to ensure that it is past the internal cervical os and is not touching the fundus · If SET PRESSURE is equal to INTRAUTERINE PRESSURE (IUP), consider increasing SET PRESSURE on pump · Consider closing or reducing outflow valve Inspect canister setup:
Tandem setup not flowing to next canister
Poor visualization
· Ensure suction source on system is securely connected and turned on · Confirm center vacuum port is attached to suction barb of lever suction or regulator suction · Ensure that tandem tubings are connected ONLY to tandem ports · Check that unused ports are closed · Ensure canister lids are secured and tight · Inspect canisters for cracks or holes · Ensure outflow and inflow valves on scope are fully open · Check that inflow and outflow tubings are not kinked · Outflow to gravity – ensure outflow tubing is placed under patient’s leg. If no return from outflow, reposition scope tip past internal os.
· Adjust focus on camera head
· Disengage camera from scope, clean optics on scope and camera · Increase SET PRESSURE on pump to increase flow rate No fluid flow after instrument recognition
· Ensure pump instrument recognition is complete and then "pump active" displays on screen · Reposition hysteroscope to ensure that it is past the internal cervical os and is not touching the fundus · Ensure fluid clamps are open on inflow tubing · Check that outflow valve is OPEN
Fluid deficit higher than anticipated by OR nursing team
· Verify scale was RESET after calibration · Ensure that ALL fluids are returning to scale · Avoid touching fluid bags to determine amount left in bag · Leave empty bags on hooks (one 3-liter bag weight = 80cc fluid) · Ensure canisters are NOT touching the legs of the roller base · Verify that tubings and/or power cords are not resting on top of the canisters Inspect canister setup:
Tandem setup not flowing to next canister
· Ensure suction source on system is securely connected and turned on · Confirm center vacuum port is attached to suction barb of lever suction or regulator suction · Ensure that tandem tubings are connected ONLY to tandem ports · Check that unused ports are closed · Ensure canister’s lids are secured and tight · Inspect canisters for cracks or holes
TruClear™ Elite and 5C Hysteroscopes – Set-up utilizing a pressure bag† Issue
Suggestion/Solution
Rapid outflow
Alter scope outflow by toggling outflow valve to 45 degrees to slow down outflow but still allow for continuous flow
No flow – uterine distention poor
· Ensure clamp on inflow tubing is open · Check for adequate pressure being applied from pressure bag/device · Ensure saline bag is not empty · Check inflow valve is in the OPEN position · Check for kinks in tubings · Ensure inflow tubing is connected and secure · Reposition hysteroscope to ensure that it is past the internal cervical OS and is not touching the fundus
Inadequate suction
· Check to make sure suction source is turned ON and produces adequate suction · Check canister lid and caps are secure and tight · Check filter is secure on center vacuum port · Inspect canisters for cracks or holes · Review all tubing connections to ensure properly attached and no kinks in tubings
Uterine distention collapses with tissue removal
Poor visualization
· Confirm suction level matches that of the suction requirement for the tissue shaver you are using as per the IFU
· Consider increasing pressure on pressure bag or increase height of pressure bag · Ensure shaver makes contact with tissue prior to and during tissue resection (footswitch engaged) · Ensure inflow and outflow valves are open · Check tubings are not kinked · Check for adequate pressure being applied from pressure bag/device · Check clamp on inflow tubing is open · Outflow to gravity – ensure outflow tubing is placed in downward position between patient’s legs · Reposition hysteroscope to ensure that it is past the internal os and is not touching the fundus · Ensure handpiece suction is ON · Consider increasing pressure on bag to increase flow rate · Check if scope is sticking to sheath during removal of sheath · Check if scope is bent
