Description

Multipurpose electric knife

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a multipurpose electrotome.

Background

The electric knife is a common instrument for modern operations, and is convenient for hemostasis during and after soft tissue incision. However, when burning soft tissues of a human body, vaporization tissue protein and fat form a lot of pungent harmful smoke, which not only obstructs the sight of the operating personnel, but also is inevitably inhaled by the operating personnel (even if wearing a mask), patients and other personnel in the operating room due to the narrow space of the operating room, thus harming the health of the operating personnel and causing symptoms such as headache, eye and mucosa inflammation. Foreign research shows that: surgical smoke is composed of 95% water or water vapor and 5% cellular debris present in particulate form. It is these particles of less than 5% that pose serious health hazards, and these particles contain mainly the following ingredients: blood and tissue debris, harmful chemicals, active viruses, active cells, inactive particles, mutation-inducing substances, and the like.

The main chemical components in the smoke are hydrocarbons, nitriles, organic amines, aldehydes and the like, wherein CO and acrylonitrile are most concerned, and other chemical components which are less in content but are more concerned are hydrogen cyanide, formaldehyde, benzene and the like. Research shows that if smoke is not eliminated in the endoscopic surgery, the organism of a patient can absorb a large amount of CO, so that hypoxia is caused, and the patient has symptoms of headache, dizziness, nausea, arrhythmia and the like. Acrylonitrile is a colorless volatile liquid, is easily absorbed by skin and lungs, and causes harm to human body by releasing cyanide. The concentration of hydrogen cyanide in surgical smoke reached 10 mg/L. Hydrogen cyanide is a colorless toxic gas, and is easily absorbed by lung, stomach, intestine and skin. The benzene concentration can reach 71 mu g/m3 in surgical smoke and 0.5-7.4 mu g/m3 in the air around the surgery, which exceeds the allowable value specified by NIOSH and OSHA. The research shows that the chemical components can cause symptoms such as headache, dizziness, lacrimation, nausea, cough, tracheitis, asthma and the like.

There is now sufficient evidence that smoke generated using ESU and laser contains active virus within a certain energy setting. Garden et al, in 1988, tested bovine fibrous papilloma (BPV) and Human Papilloma (HPV) DNA in surgical smoke using different modes and energies of a CO2 laser and showed that the laser-generated vapor contained intact HPV DNA. The Stanford university investigator Johnson et al found active HIV virus in the low temperature smoke of Midasrex high speed abrasive drilling and Stryker laparoscopic surgery, with a survival time in surgical smoke of up to 14 days. Thus, the surgical personnel are at increased risk for hepatitis, HIV, HPV and the like.

Numerous studies have found that lasers, electrosurgical devices and ultrasonic blades can vaporize intact tissue cells and blood components. These vaporized cells are still viable and can infect surgical workers. Research shows that after mouse melanoma cells are treated by electrocautery, active melanoma cells exist in surgical smoke, and the research can explain the phenomenon that the tumors are still regenerated after the tumors are excised by laparoscopic surgery. In laparoscopic surgery, vaporized tumor cells may leak out through the slit around the laparoscopic cannula, and the prevention damage caused by both the laparoscopic cannula and the trocar may result in implantation of the tumor cells.

PM2.5 fine particles can be generated during surgery. The Wangcai and the like, which are affiliated to the tumor hospital of the university of Fudan, find that the concentration of PM2.5 in 40cm of the operation part can quickly reach 149.4-245.7 mu g/m3 which is 2-4 times higher than the normal value 3-6 s after the first incision of the operation. In laparoscopic surgery, after the needle valve of the cannula is opened for 3s, the concentration of PM2.5 in the air reaches the peak value of 517.5 mu g/m3, and a serious pollution state is reached. When a human body inhales or contacts the small particles for a long time, various diseases such as pulmonary fibrosis, pulmonary congestion, pulmonary emphysema and the like can be caused. In addition to these fine particles, slightly larger particles may also be present, and particles of 5 μm or more may be deposited in the nasal cavity, throat, trachea, bronchial wall, etc., and may also cause a series of respiratory problems.

In 1992, Gatti, Bryant, et al collected smoke produced during breast plastic surgery and found that the strain Salmonella TA98 was mutated. In 1999, Zhang Xun et al performed genotoxicity studies on ESU smoke and found that smoke extracts were able to exert a damaging effect on the DNA of strain TA1535/PSK 1002. Other studies have shown similar results. Further studies have shown that surgical smoke is mutagenic to tobacco and that hazards from exposure to smoke can accumulate.

Therefore, sometimes the assistant uses the vacuum suction tube to suck the generated harmful gas when the operator uses the electric knife, but the assistant occupies one hand of the assistant, and other auxiliary operations of the operator such as pulling a hook, wiping blood, separating soft tissues, clamping and the like are affected. Therefore, the use of the traditional electrotome can either harm the health of operators and people in the operating room or influence the assistant to assist the operation of operators.

Comparative example

According to the traditional electric knife, the electric knife and the negative pressure suction tube are arranged separately, and an assistant can hold the negative pressure suction tube with one hand to suck harmful gas generated when an operator uses the electric knife.

The use method of the traditional electrotome comprises the following steps: taking a wrist cyst excision operation as an example, the same doctor performs the operation, after connecting a pipeline, an operator needs to pass through and wind a power line at a holding ring of one surgical forceps and clamp the surgical forceps on a surgical drape, and under the condition of insufficient surgical instruments, the subsequent operations such as clamping and the like can be influenced; in operation, if the length of the power cord is to be adjusted, the wound part of the grip ring of the surgical forceps needs to be detached, and the grip ring of the surgical forceps passes through the wound part again after being adjusted, so that the surgical forceps is troublesome and long in time. When the electric scalpel is used for cauterizing soft tissues, harmful and unpleasant smoke is generated, which is not beneficial to the health of all personnel in an operating room, firstly, an operating doctor uses the negative pressure suction tube for suction, the thick and large hose part is difficult to fix by an operating forceps, if the hose is not fixed, the hose pulls the suction tube on an operating table, which is not beneficial to operation, and the suction tube has the risk of being pulled to the ground; if the fixation is performed by using forceps, the portion of the tube to be fixed is easily pleated so that the suction is not smooth as the negative pressure tube changes its position. In addition, the negative pressure tube needs to be held by one hand of an assistant, so that the operations of pulling a hook, wiping blood, separating and clamping the tube are influenced, and the efficiency of the operation is reduced.

The traditional electrotome has the following disadvantages in the use process:

firstly, the fixation and adjustment of the pipeline are inconvenient, and the operation forceps are additionally occupied.

Secondly, the negative pressure suction is used to independently open the bag, the efficiency is low, and the generated packaged garbage is more.

Third, some physicians may be cumbersome and do not specifically require the use of a suction tube. However, once negative pressure suction is not used, the nasal smoke generated in the operation will have adverse effects on the health of the personnel in the operating room, such as the operating physician.

Fourthly, some doctors may not fix the suction hose because of inconvenience or insufficient instruments, which not only makes the negative pressure suction operation inconvenient, but also is liable to have a danger that the suction hose falls,

fifth, if the suction hose is fixed, an additional surgical forceps is required, and the fixing method still easily affects the suction operation.

Sixth, the suction tube needs to be held by an assistant, which affects the assistant operation of the operator and reduces the efficiency of the operation.

Therefore, the traditional electric knife is not beneficial to the health of personnel or reduces the operation efficiency.

To sum up, the utility model combines two instruments into one, when the electric knife is used in the operation, the operator can burn and smoke with one hand without holding the negative pressure suction tube 2 by an assistant; when needing to suck liquid, the operator only needs to stretch out the negative pressure suction tube 2 with the forefinger forward sliding block 4, can accomplish, has both ensured personnel's health, has simplified the flow again, has improved efficiency, has purified the operating table, can also reduce the packing rubbish.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
