Description

Drying device based on endoscope instrument is used

Technical Field

The invention relates to the technical field of medical instrument drying, in particular to a drying device based on endoscope instrument application.

Background

Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. The traditional method of the retrolaparoendoscopic surgery is to make three small 1 cm incisions on the waist of a patient, insert a tubular working channel called trocar respectively, and carry out all the following operations through the three channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved. Compared with the traditional operation, the laparoscopic operation is popular with patients, especially has small scar after operation and meets the aesthetic requirements, young patients are more acceptable, and the minimally invasive operation is the general trend and pursuit target of surgical development. Currently, the golden standard of laparoscopic surgery is cholecystectomy, and most of the general surgical operations, laparoscopic surgery, are generally performed. Such as appendectomy, gastric and duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenal gland resection, ovarian cyst removal, extrauterine pregnancy, hysterectomy and the like, almost all surgical operations can adopt the hand with the increasing perfection of laparoscopic technology and the improvement of the operating level of laparoscopic doctors.

At present, the existing surgical endoscopic surgery accounts for higher and higher proportion in clinic, and is particularly widely applied to thoracic surgery, gynecological surgery and other surgeries, the cleaning work of the instruments before disinfection and sterilization is very complicated, a large amount of manpower resources are consumed, particularly, the drying process is slow after cleaning, the recycling frequency of the instruments is influenced, and the efficiency of clinical work is further reduced. At present, the drying method of the endoscope tube sheaths clinically comprises the step of blowing and drying the endoscope tube sheaths by aligning an air outlet of a medical high-pressure air gun with one end of the endoscope tube sheaths. However, this drying method has the following disadvantages: the water droplet residue on the inner wall of the endoscope sheath influences the drying speed; because endoscope tube sheath length reaches 20 ~ 25cm, and every endoscope tube sheath thickness is different, consequently the air current that high-pressure air gun produced gets into endoscope tube sheath back through endoscope tube sheath one end, can produce the air current swirl, influences the air current speed to the efficiency of drying is weathered to the reduction.
