Description
Technical field
This utility model belongs to field of medical auxiliary equipment, particularly one fume cleaning removal device in laparoscopic surgery.
Background technology
Peritoneoscope is a kind of apparatus with minisize pick-up head, laparoscopic surgery is exactly the operation utilizing peritoneoscope and related equipment thereof to carry out: use cold light source to provide illumination, lens of laparoscope (diameter is 3 ~ 10mm) is inserted intraperitoneal, the image using digital camera technology that lens of laparoscope is photographed conducts to rear class signal processing system by optical fibers, and is presented in real time in dedicated monitor.Then doctor is by the image of patient organ's different angles shown on monitor screen, carries out analysis and judges, and use special laparoscopic instrument to perform the operation to the state of an illness of patient.
Laparoscopic surgery many employings 2 ~ 4 hole operation method, one of them opens on the umbilicus of human body, avoid the cicatrix leaving strip at position, patient abdominal cavity, after recovery, the wire cicatrix of 1 ~ 3 0.5 ~ 1 centimetre is only left at position, abdominal cavity, can be described as wound surface little, the operation that pain is little, therefore also someone is referred to as " keyhole " operation.Carrying out of laparoscopic surgery, alleviates the pain that patient operates on, and makes the convalescent period of patient shorten simultaneously, is a development in recent years operation project rapidly.
Laparoscopic surgery compared with traditional operation, the dark welcome by patient, especially postoperative scar little, meet aesthetic requirement again, Young patients more gladly accepts, and Minimally Invasive Surgery is the general trend of surgery development and pursues a goal.At present, the goldstandard of laparoscopic surgery is cholecystectomy, and in general, the operation of most of general surgery, laparoscopic surgery can complete.As appendectomy, taste-blindness rate Repair operation, hernia repair art, colectomy, splenectomy, adrenalectomy, also have ovarian cyst excision, ectopic pregnancy, hysterectomy etc., along with the day by day perfect of laparoscopic technique and the raising of peritoneoscope doctor operant level, nearly all surgical operation can adopt this operation.
But while completing these operations, laparoscopic surgical instruments (as single-stage or bipolar coagulation, ultrasound knife, Ligasure, laser etc.) also creates poisonous operation smoke, and these operation smokes refer to air mesoptile shape thing, aerosol and steam body.Water primarily of 95% or steam and 5%, with the cell debris composition of particle shape existence, can be seen, also can smell.The contained harmful substances that mainly contains has virion entrained in CO, acrylonitrile and smog even to have carcinogenecity (as: toluene, benzene, dimethylbenzene etc.).Patient is during laparoscopic surgery, and all the time in the face of the potential risk of operation smoke, the smog produced in abdominal cavity is absorbed by peritoneum, causes the increase of metahemoglobin and carboxyhemoglobin amount in blood samples of patients, thus causes erythrocyte oxygen carrying capacity to decline.Operation smoke not only affects degree of getting a clear view and the operation seriality of operation, and the operation smoke of discharge directly produces respiratory inflammation to the staff of operating room, pulmonary stimulates and the body harm such as carcinogenic toxicity, and formed with air be carrier source of infection contaminated operation between air; Still unknowable according to the long term infringement of current pertinent literature report to patient and operating room technician.
Get rid of the present situation of smog at present in situations in the surgery room: (1) traditional method is that the air bleeding valve opening puncture casing directly gets rid of smog, until get a clear view shut valve again.As valve-off not in time, pneumoperitoneum pressure can be caused to reduce, valve need be shut and wait for and could continue to perform the operation after pneumoperitoneum pressure rises again, break operation seriality.Peritoneoscope stack effect causes air-flow to pour into operating room technician by laparoscope puncture casing, is directly discharged in operating room, causes the pollution of operating room technician's body harm and environment.(2) adopt self-control controllability suction pump, though can continuous sucking smog, harmful operation smoke still can be discharged into operating room or negative suction suction pump without harmless process, causes equipment pollution.And need to continue to pour carbon dioxide to maintain pneumoperitoneum pressure in operation, add the risk of carbon dioxide use amount and patient's absorption.
