Description

Minimally invasive surgery cutter for breast tumor with bionic maggot mouth

Technical Field

The invention relates to a minimally invasive breast tumor surgical cutter with bionic maggot ports, and belongs to the technical field of image surgical operations.

Background

The minimally invasive surgery refers to surgery performed by using modern medical instruments such as a laparoscope, a thoracoscope and the like and related equipment. The advent of minimally invasive surgery and widespread use in the medical field has been a matter of the last decade. Accidental completion of the first example LC by Mouret in 1987 by french doctor Mouret did not suggest that it marked the birth of a new medical milestone. The creation of a minimally invasive concept is due to the progress of the overall medical model, which is driven by the "holistic" therapeutic view. The minimally invasive surgery focuses on improvement and rehabilitation of psychology, society, physiology (pain), psychology and life quality of a patient, is attached to the patient to the greatest extent, and relieves pain of the patient. The minimally invasive surgery does not need to be operated, only 1-3 small holes with the size of 0.5-1 cm are needed to be opened on a patient, the patient does not leave scars and pain, and the whole process of examination, treatment and rehabilitation can be completed in 3-5 days. Reduces the harm of the traditional operation to the human body and greatly reduces the inconvenience and pain of the patient caused by the disease. The minimally invasive surgery has the advantages of small wound, light pain and quick recovery. The minimally invasive surgery has five advantages: the wound is small: a tiny incision is made on the abdomen, 0.5cm to 1cm, basically no scar is left, and the name of a keyhole is used. ② the pain is light: the pain of the patient is small, the operation adopts intravenous anesthesia, and the operation of the patient is completed in a sleeping state. ③ the recovery is quick: greatly reduces the damage to the viscera and the interference to the functions of the viscera, and shortens the recovery time after the operation. The hospitalization time is short: generally, the patient can get out of bed after 6-8 hours of operation, can eat food after 12-24 hours of anal exhaustion, is discharged from hospital for 3-5 days, basically recovers after one week, and has relatively low cost. Less bleeding: little bleeding during the operation: the minimally invasive surgery has clear visual field, the blood vessel treatment can be more delicate, and the adoption of advanced hemostatic instruments such as an ultrasonic knife and the like is helpful for reducing the amount of bleeding. Fly maggots are larvae of flies. Mainly breeding in human and animal manure piles, garbage and rotten substances, eating the manure and the rotten substances, and some living in rotten animal bodies. The newly hatched larvae are grey white and light-fearing, move and feed 2-10 cm below the surface layer of the feed, grow at a very high speed, grow 1cm long and weigh about 30 mg for 4-5 days, and begin to pupate. The fly maggots are not sufficient, the rear end of the fly maggots is blunt and round, and the front end of the fly maggots is tapered gradually. The length of the 3-4 day-old larva is 8-12 mm, the weight is 20-25 mg, the mouth of the larva is in a claw shape, and the larva has the habit of keeping out of the sun, drilling, gathering and piling. Breast cancer is one of the most common malignant tumors in women, and the incidence rate accounts for 7-10% of all malignant tumors in the whole body according to data statistics, and the incidence rate of the breast cancer is higher in women before and after menopause and only about 1-2% of breast patients are male after the women are only uterine cancer and the incidence rate of the breast cancer is often related to heredity and between the ages of 40-60. Malignant tumors usually occur in mammary gland epithelial tissues. Is one of the most common malignant tumors which seriously affect the physical and mental health of women and even endanger life, and breast cancer is rare for men. The common surgical method is radical breast cancer: halsted and Meger published the operation principles of radical breast cancer treatment in 1894, respectively: firstly, a primary focus and regional lymph nodes are excised in a whole block; secondly, cutting off all mammary glands and breast large and small muscles; the axillary lymph nodes are completely excised in a whole block, Haagensen improves radical operation of breast cancer, emphasizes that the operation is especially thorough, and mainly comprises detailed skin flap stripping; after the skin flap is completely separated, the big and small muscles of the chest are cut off from the chest wall and turned outwards; thirdly, the armpit is dissected, the long diameter of the chest should be preserved, if the armpit has no obvious enlarged lymph node, the thoracic and dorsal nerves can also be preserved; fourthly, the skin is implanted to the chest wall defect uniformly, and the common complications in the operation include: axillary vein injury: most of the reasons are that the patients do not clearly dissect fat and lymph tissues around the axillary vein, or the patients are too close to the main trunk of the axillary vein when the axillary vein branches are cut off, so that a few branch broken ends are clearly exposed and retained, which is important, and pneumothorax: when the rib ends of the major pectoralis and minor pectoralis muscles are cut off, small blood vessels clamping the chest wall penetrate through the branches and the lower forceps are too deep, so that intercostal muscles and pleura are touched and the tension pneumothorax is caused, and postoperative complications are as follows: subcutaneous fluid accumulation: the skin necrosis is mainly prevented by adopting multiple suture fixation and continuous negative pressure drainage between subcutaneous and chest wall tissues due to poor fixation or unsmooth drainage of the skin: skin suture tension and skin slice thinness can be the reasons for the occurrence of the defects, when the skin defects are more, skin grafting is adopted, edema of the upper limbs on the affected side is limited, lifting of the upper limbs on the affected side is limited: mainly caused by the reduction of postoperative activities and the traction of subcutaneous scars, therefore, functional exercises are required to be performed early after the operation, and the lifting freedom degree can be basically achieved about one month after the operation. Therefore, in the treatment process of the breast tumor, if minimally invasive surgery is adopted for treatment, great benefits are brought to the postoperative patients, and postoperative healing and rehabilitation are facilitated. The operation is an indispensable treatment mode even for quickly and effectively removing the breast tumor, so that how to make the operation wound as small as possible and the effect of removing the breast tumor tissue cells is good becomes a big problem to be solved urgently, therefore, the minimally invasive operation cutter is manufactured by utilizing the characteristic that the fly maggots are good at drilling and the structural characteristics of the bionic fly maggot claw-shaped food taking port, so that the minimally invasive operation cutter is very tiny and efficient, the breast tumor tissue blocks can be quickly and thoroughly removed, and finally, the purpose that the breast tumor operation wound as small as possible and the effect of removing the breast tumor tissue cells is good is achieved.
