1、 Analysis of common faults of optical lens and Countermeasures
Arthroscopic lens is the central part of the arthroscopic system, which is directly related to the quality of arthroscopic surgery image. Joint lens includes light transmission system, optical fiber, optical cable connector, metal sheath and eyepiece. Because of the fine structure of the optical lens, it is easy to be damaged at its objective end, metal sheath, optical cable thread end and eyepiece end.
Common problems are as follows:
?、?Broken glass at objective and eyepiece ends: collision with air and surrounding equipment; collision with instrument box;
?、?Wear and deformation of objective lens end: collision with cutter during operation;
?、?Fogging at eyepiece end: leakage of sealing ring;
?、?Bending deformation and dent of metal sheath:
?、?Collision with air and surrounding equipment; collision with equipment box;
?、?Improper use. Cable connector crack, water: after use, immediately wash with cold water or soak in saline.
?、?Collision prevention: the lens is the most delicate and expensive in the arthroscopic equipment, therefore, the operation process should be very careful, do not collide with hard objects; the specialized group is divided, and the specialized nurses cooperate with the operation;
?、?There should be a maintenance set or a special lens box when the lens is recycled, and a one-to-one separate handover means that the hand washing nurse and the full-time nurse in the instrument room hand over one-to-one, do not place the lens in the instrument box, distinguish the obligations, and prevent mixing;
?、?After the lens is used, it can be cleaned before the connector is cooled, so as to prevent the immersion of physiological saline when the lens is disassembled;
?、?The wear of the objective lens is mainly caused by improper collision during the operation of the cutter, which is mostly caused by the operator's unskilled technology;
As for the endoscopists who are just able to operate independently, although their qualifications and class hours are up to the standard, their clinical operation experience is not rich. The surgeons usually perform simple operations such as arthroscopic exploration or liquidation. As for such doctors, we can complete the operation by using the domestic lens, and remind the doctors to be careful of the lens during the operation.
