Endoscopes are essential tools in the medical environment and have to be cared for carefully because they’re easily bent and damaged. This article examines the most frequent repairs these devices require and discusses how to prevent such damages.
Common Flexible Endoscope Repairs
Flexible endoscope repair is essential for keeping these expensive but relatively fragile medical instruments in service. The most frequently seen problems give rise to the repairs done in this section.
1. Air or Water Channel Replacement
Changing the air or water inlet is a common repair job, usually to ensure that fluid can flow into it during operations. This repair is essential to maintain the endoscope’s performance.
2. Angulation Adjustment
Adjustment of the angle is another common repair to allow for accurate control of movements within the patient’s body.
3. Air/Water Nozzle Unclog or Replacement
If air or water breaks down during procedures, there will be no way to continue using it, and the flow must unclog or replaced.
4. A – Rubber Replacement
This particular procedure involves replacing the rubber part of the endoscope, and is used to resolve problems with its flexibility or sealing.
5. Variable Stiffness Adjustment
Periodic adjustment of the variable stiffness relies on tailoring its performance to various medical situations.
6. Angle Drive Rebuild
The angle drive rebuild is a repair for the articulation apparatus on an endoscope.
7. Control Button Replacement
Only then will there be a need to replace control buttons in order to overcome problems with the endoscope, its user interface, and its functionality.
8. Light Guide Tube/Universal Cord Replacement
The light guide tube and universal cord must be replaced in order to maintain the quality of lighting.
9. Biopsy Channel Replacement
Replacement of the biopsy channel is, therefore, essential if testing capabilities are to be maintained.
10. Suction Channel Replacement
Replacing the suction channel ensures that medical procedures are done without problems.
11. Replace the suction cylinder or air/water cylinder
Repair to the endoscope’s fluid control mechanism is concerned with replacing a suction cylinder or air/water cylindrical unit.
12. Minor & Major Fluid Invasion
Splashing around it and the endoscope in minor or significant fluid invasion must be repaired to prevent damage to internal parts as well.
Hence, these kinds of repairs are very important to understand and handle so that flexible endoscopes can remain usable longer. Careful care and handling are essential, both to avoid breaking the delicate parts, such as its light fibers and also so that medical treatment can be successful.
Causes and Prevention of Damage to Biopsy Channels
Flexible endoscopes are prone to damage to the biopsy channel. Doctors must, therefore, know how best to prevent such occurrences from happening.
Causes of Damage:
●Using Damaged/Incorrect Accessories: Using accessories that are in poor condition or those that are simply not fit for the endoscope can cause severe damage to the biopsy channel.
●Improper Care & Handling: Over-coiling the insertion tube, performing leak tests, or cleaning scopes in sinks and basins of insufficient size also pose potential threats to biopsy channels.
●Twisting or Excessive Torque Force: Excessive torque force, or twisting of the insertion tube while using it, can cause damage and affect biopsy channel function.
●Damage to Insertion Tube or Bending Section: If the insertion tube or bending section is damaged, this will lead to collapsing of the forceps channel, thus distorting overall performance.
The causes are important to understand, but just as crucial understands preventive techniques that will extend the lives of biopsy channels.
If healthcare professionals keep these preventive measures in mind, the risks to patients posed by damage to a biopsy channel can be reduced. These measures help preserve flexible endoscopes from malfunction and better maintain their service lifetime.
Causes and Prevention of Damage to Bending Rubber in Endoscopes
Due to the use of bending rubber in an endoscope, if there is damage, this will considerably impact its flexibility and could even lead to fluid invasion or pathogens being created. If the bending rubber is to maintain its integrity, understanding its causes and carrying out preventive measures are crucial.
Causes of Damage:
●Improper Care & Handling: Examples include stacking of scopes, having sharp objects near the distal tip, or haphazard transportation (including patient bites).
●Stretched or Aging Bending Rubber and Epoxy: The rubber or epoxy can be bent, but it may age and stretch out over time.
●Improper or Inadequate Storage Areas: Improper storage areas leave the bending rubber exposed to conditions that can promote deterioration with time.
●Deformed or Fraying Bending Section or Mesh: If the bending portion of each piece is even slightly deformed or frayed, it causes damage to the bending rubber.
Ways Bending Rubber is damaged:
●Passing the scope through a hole too small, like gastroscopy mouth guards or bronco gladiator adaptors used for patient air exchange.
●The bending rubber is nibbled at by the patient.
●If the bending rubber is cut or punctured by accident.
●Over-pressurizing the flexible endoscope to test for leaks will stretch out its bending rubber.
●Normal wear and tear.
●Use of cleaners or lubricants not designed for bending rubber.
●Avoid Contact with Sharp Surfaces or Instruments: It is also essential to prevent the bending rubber and sharp objects or tools from coming into contact.
●Transport Scopes Separately from Accessories: Forceps spray nozzles, and other accessories should be transported separately from the scope in order to limit the possibility of damage.
●Keep the Bending Section and Light Guide Connector Separated: This keeps the bending section from being damaged by contact pins and ports in the light guide connector.
●Avoid Stacking Endoscopes: Endoscopes should never be piled together during transportation or cleaning so as to avoid the pressure that could deform the rubber.
●Use Bite Blocks: The use of bite blocks not only protects the bending section but also allows for close inspection to see if there are any rough edges.
●Release Leak Test Pressure Completely: Release the pressure after leak testing is performed. If the scope has been left pressurized, this loosens the bending rubber, which is thus less impermeable.
Healthcare professionals should perform these preventive measures to avoid damaging the endoscope’s bending rubber and reduce their chances of breaking it.
Causes and Prevention of Damage to Bending Section Mesh in Endoscopes
The bending section mesh is easily damaged in endoscopes, and causes need to be thoroughly understood and preventative measures taken.
Causes of Damage:
●Patient Bites: Biting into the endoscope can break through the mesh and warp its forming structure.
●Improper Care & Handling: Improper handling and care may also result in damage, pointing out the necessity for correct procedures.
●Excessive Torque to the Angulation System: If excessive torque is applied to the angulation system, then breaching of the bending section mesh may occur.
●Aging Mesh or Aging Bending Section: With age, an endoscope’s mesh and bending section can wear out relatively easily.
●Fluid Invasions: Fluid invasions can be harmful, for example, damaging the mesh in the bent portions of endoscopes. These fluids may even damage all parts of an entire endoscope.
●Avoid Contact with Sharp Surfaces or Instruments: To protect the bending section mesh, one must take care to prevent contact between sharp surfaces or instruments and the rubber.
●Transport Scopes Separately from Accessories: To prevent damage in transport, scopes need to be shipped separately from accessories (such as forceps and spray nozzles).
●Keep Bending Section and Light Guide Connector Separated: The bending section and the light guide must be detachable. Otherwise, the sharp corner of a contact pin or port can damage either separation point.
●Avoid Stacking Endoscopes: Do not transport or clean endoscopes in heaps, as this can cause pressure to build up on the mesh bending section and damage it.
●Use Bite Blocks: Bite blocks are particularly important to prevent the bending section mesh from being damaged. Moreover, going over the bite blocks in advance makes sure that there are no sharp edges.
●Release Leak Test Pressure Completely: Also, you must completely depressurize after leak testing. He says that leaving the scope pressurized will allow stretching of the rubber bending section and decrease puncture resistance after the scope is locked in.
It’s necessary for healthcare professionals to take these preventive measures to avoid damaging the bending section mesh, thus helping preserve endoscope integrity so that medical procedures go ahead as planned.
