Lasers in Surgery
Abstract: The laser is gaining increasing popularity in the medical field because of its broad application, efficiency, and improvement in overall ease of the procedures in which it is used.. The laser can treat an enormous range of ailments. The chronic nighttime snorer can give those around him relief by a simple procedure with the laser. In dermatology, the laser can be used for removing moles, tattoos, birthmarks, treating wrinkles, and possibly destroying skin cancer. The once dreaded trips to the dentist may become less painful since the laser is helping to replace the drill and Novocain. The laser also is becoming increasingly popular in orthopedics for treating shoulder, knee, and back ailments. For women many gynecological problems ranging from infertility to endometriosis can be treated with the laser. For small, precise work the laser is indispensable such as in the eye. Unfortunately, since laser medicine is still rapidly developing, it has experienced its pitfalls in some areas like cardiology. Overall, the laser is an invaluable substitute for the scalpel of the past, and the laser's possibilities for the future are broad and promising.
Lasers in Surgery
The laser is creating a bloodless revolution. A laser works by using heat to obliterate cells. As it cuts, blood vessels are sealed, and tissue is sterilized. The laser is particularly useful in regions of the body that are difficult to reach. Many types of lasers are used in surgery, and the kind (gas, liquid, solid, visible, or unseen) varies based on the procedure. Choosing the laser to fit the procedure is essential because otherwise damage such as fires, eye harm, a charred cheek, a chipped t...

From the beginning of “The Metamorphosis”, the character Gregor Samsa, woke up one morning transformed into an insect without any explanation. He was unsure of what was happening to him or why. Samsa, days were routinely the same, giving up and going to work every day, no matter what. Gregor’s father had owned a business that failed and left the family in debt,
The parents of Gregor ultimately failed to care for him in a time where he needed the emotional support. They also neglected Grete as well and handicapped her true potential as a musician. The biggest betrayal of all; however, took place after Grete quit believing in Gregor and left him to die. While Gregor changing into a bug did put new stress on the family, it was the betrayal of each other that lead to their demise. In conclusion the Samsa family proved to be unloyal amongst each other, and Gregor happened to lose his life because of
Gregor’s father demotes societal views of himself by his actions. Gregor’s father depends on Gregor for the income for the family. When Gregor morphs into a bug, Mr. Samsa reluctantly becomes the sole provider for his family. Getting a ...
Gregor Samsa’s mother, whose name is never revealed, is a physically and constitutionally weak woman. She cares dearly for Gregor which is first shown by her distress as Gregor does not wake up at his usual time. It is evident that Gregor’s mother has the hardest time coping with his transformation. She can not bear to lay eyes upon Gregor. Though she has trouble adjusting, she doesn’t stop loving her only son. As Gregor’s mother and sister begin to move furniture out of his room, his mother stops to contemplate whether this is the right course of action. As Sheldon Goldfarb states in his critical essay, “When his mother and sister start removing his furniture, his mother's second thoughts provoke him to resist: he does not want to give up his human past and the possibility of returning to it” (Goldfarb). On the outside, Gregor’s mother reacts with repulsion at the sight of the bug, but on the inside still cares deeply about her son underneath. Gregor is able to see this and it gives him new hope.
Thirdly, he suffers isolation from the physical world, which he is no longer able to participate in due to his presence and lack of mobility. Lastly, he suffers isolation from other people around him, especially his family. By the end even his sister, Grete, the most compassionate member of the family, explanations that they should stop thoughtful of the creature as the person they knew. She says that “the fact that we’ve believed it so long is the root of our trouble” (Kafka 48), which can be taken to mean that at some point Gregor stopped being a person not only because of his entrance but since of his non-conformist actions. The beating he receives from his father shows the extent of the cruelty he endures, though his father knows that “family duty compulsory the conquest of disgust and the use of endurance, nothing but patience” (Kafka 36). The tragedy is that this alienation ends up killing Gregor, who “dies not as a vermin, but as a human being thinking of his family”. The transformation is an indication of the breakdown of Gregor’s psyche and alienation within his self. The reader is not told how the transformation
The story The Metamorphosis revolves around Gregor Samsa, a devoted son and brother who works tirelessly to provide for his family, waking up finding out that he has been transformed into a larger than life insect. Franz Kafka enlightens the readers to how being dependent on one person can lead a family to being weak when that support system is ripped away from them. The situations that Gregor is put into knocks him down from the head of the family into nothingness while at the same time boosts his family from that nothingness into being a strong support system for each other. Gregor 's transformation, his dependency on his sister for food, his injury, the family choosing strangers over him, and ultimately his death are all things that lead to this downfall, or metamorphosis.
In Kafka's Metamorphosis, Gregor Samsa, whose life is controlled by his work and family, wakes up a giant insect. Prior to this metamorphosis, Gregor obsequiously goes about his life of routine, despite his hatred for his works and a complete emotional disconnect between Gregor and the family which he works so hard to support. Gregor's metamorphosis marks an important transition in Gregor's life as well as an escape from the monotony of his previous life. Sokel theorizes that Gregor's metamorphosis allows Gregor to express previously repressed feelings of rebellion while not being held accountable for his these tendencies stating "The metamorphosis enables Gregor to become free and stay "innocent", a mere victim of uncontrollable calamity."(206). While his metamorphosis does allow him to free himself from some of the suffering, it traps him in a new cycle, trapped by his families obligation to help him. Throughout his life, Gregor is plagued by a cycle of suffering caused by his families dependence on him which leads to further alienation leading to a dependence on his family's dependence. Though Gregor is broken out of this cycle in his metamorphosis he does not find true freedom until his death.
Despite his situation Gregor still feels that he can go to work. However he proves unable to do this when he encounters so much trouble when trying get out of bed and open the door. Gregors manager comes to his home, wondering why he didn’t show up for work. The manager gets irritable and tells Gregor in the presence of his family that he wanted a real explanation as to why he would not come out of his room. Gregor finally has enough strength to open the door with his mouth but by that time his manager had already left. He is now saddened and in fear that he lost his job, because he knows that he is the financial “backbone” of the family. When his family finally sees that he is an insect they are immediately disgusted. His mother faints, and his father forbids his mother and daughter to see him. Grete, Gregors ...
In The Metamorphosis, by Franz Kafka, Gregor’s evolution to an insect symbolizes the loss of thorough communication, representing the disconnection of the individual from his family and his surroundings. Through this metamorphosis, the once loving family begins to remove itself from any past interactions with Gregor. In addition, the setting and surroundings of Gregor completely overcome him and persuade him to lose hope. The family and surroundings, not the change to an insect, lead Gregor towards death. Not only do the uncontrollable surroundings change Gregor, but so does the family.
Because Gregor is no longer capable of filling the role of "provider", his actions no longer define the lives of his family, and they are freed from inauthenticity by this revelation. Much like the philosophers of the existentialist movement, Gregor's family realizes that in the face of absurdity, the only choice one has is to define their own existence. As time wears on, Gregor's family becomes contemptuous of the burden which comes from caring for him and hiding him from the eyes of the public. In reaction to their contempt, each chooses to prevent Gregor's new dependent role from hindering their authenticity. The father feels a sense of renewed pride in once again being the head of the household.

He had worked a job he did not enjoy, and even wanted to send his sister to music school. Kafka wrote Gregor out as a good son, a kind brother, and a hard worker. He was, by no means, a bad person. This makes readers question exactly why he was turned into a bug, and died a sad, lonely death. After careful examination of this novella, readers can learn why. Kafka was not trying to make a point out of Gregor, but of his family. His family turned their backs on him of a time of need. Kafka writes, “the apple remained lodged there in his flesh, a visible memento, since no one dared to remove it-seemed to have reminded even his father that Gregor, despite his current lamentable, repulsive form, was a member of the family who should not be treated like the enemy, for family duty dictated that the others swallow down the disgust he aroused in them and show him tolerance, only tolerance (Kafka 1902).”Kafka seems to be saying that family duty is what kept the family members from hurting Gregor. But, family duty does not involve love or compassion or gratefulness. They must “deal” with him. Family duty essentially comes down to suffering the company of ones family because they have no other
In the average family, parents try to recognize their children and treat them all equally, but that was not the case with the Samsas, where they recognized their son Gregor no more than a source of income. When Gregor was not able to work anymore after the metamorphosis, the family rejected his existence as a bug and he was neglected and treated with cruelty. The effect of financial pressure on Gregor’s social life took place before the metamorphosis, because Gregor has devoted all his effort and time into his job to serve the family’s needs, in the meantime he ignored his social life, which lead to an extreme sense of alienation. From a personal interpretation, Kafka tries to present Gregor as a frustrated building block of the bureaucratic system, which leads to the belief that Kafka was criticizing bureaucracy and prove that it is alienating on a much larger scale than one person; rather it could alienate an entire society or even a nation.
Surgery comes from Greek via Latin: meaning "hand work". Surgery is an ancient medical procedure that uses specific techniques on a patient to investigate and treat a small or severe condition such as disease or injury. Surgery can be used for different reasons; some might be to help improve body function or appearance, and some maybe for religious reasons. There are many types of surgeries (e.g. neuro, cardiac, plastic, oral, podiatric etc., etc.). Surgery originally started in France in the 16th century, but was very rarely used. This French surgery was also only preformed for minor uses. Surgery back then was very risky and only a few patients survived. Now you might be thinking, what kind of doctors were those idiots, but think again, does surgery only need a very highly educated surgeon? The simple answer is no. The reason or should I say the greatest reason was that of the tools.
We have all at some point in our lives used or seen someone use a laser.
