Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a novel multi-point biopsy forceps.
Background
In recent years, endoscopy has been widely used as a diagnostic aid in clinical medical examinations. When the lesion part in the body of a patient is inspected, the biopsy forceps can extend into the body through the endoscopic forceps channel to clamp the lesion tissue. Endoscopic sampling is a popular diagnostic method because of its minimal trauma and pain, but current biopsy forceps suffer from problems in use.
Biopsy forceps are indispensable tools for taking pathological specimens in endoscopy, and if contaminated biopsy forceps are used for operation and specimen taking, nosocomial infection can be caused. The pen operator analyzes the reasons for carrying bacteria and the sterilization method of the biopsy forceps as follows.
And (3) biopsy forceps bacteria-carrying reason analysis: when endoscopic examination is carried out, in order to facilitate the observation of the expansion of the gastric cavity and the intestinal cavity, the cavity is injected with gas, the pressure in the cavity is increased, and mucus, blood and secretion in the alimentary canal are pressed into a biopsy forceps sheath. The structure of the biopsy forceps is not provided with a flushing hole, and the inner core is not easy to flush, clean, disinfect and sterilize. The automatic cleaning ultrasonic atomization endoscope sterilizing machine is provided with an endoscope sterilizing system and a biopsy forceps sterilizing system for reasons that the sterilizing machine is not thoroughly sterilized. The disinfection procedure comprises pressure cleaning, atomization disinfection and pressure cleaning, and the water source and the disinfection solution are used once and then discharged. The dirt inside the sheath of the biopsy forceps cannot be strategically directed to drain the dirt fluid out. When the sterilizing machine works, the surface of the biopsy forceps is only cleaned and sterilized, and dirt hidden in the sheath cannot be sterilized, so that the biopsy forceps are not sterilized completely. In the experiment, the biopsy forceps disinfected by the disinfection machine are taken out and vertically hung, and after minutes, the discharged mucus can be seen at the forceps flap at the lower end of the biopsy forceps, and a large amount of bacteria can be cultured, so that the fact that the dirty liquid is contained in the sheath of the biopsy forceps is further verified. The vertical suspension soaking method is characterized in that the biopsy forceps are vertically suspended for soaking and disinfection, after the biopsy forceps are primarily cleaned, the biopsy forceps are vertically suspended for soaking in 2% valeraldehyde solution, and secretions entering a sheath are drained out under the action of gravity for disinfection and sterilization. In addition, the difference in the disinfection time is one of the reasons for the obvious difference in the disinfection result, which suggests that the extension of the disinfection time is important for improving the disinfection effect. Through the observation of bacterial culture, the disinfection effect still reaches the aseptic requirement after the disinfectant is used for 2 weeks. Therefore, sterilization of the forceps is recommended using a vertical hang dip sterilization method.
