Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a device for taking out hysteromyoma by rotary cutting.
Background
Hysteromyoma is the most common benign tumor of the female reproductive system, the incidence rate accounts for about 1/5 of women of childbearing age, and the operation treatment mode is divided into simple hysteromyoma digging-out or total hysterectomy. With the improvement of minimally invasive requirements of people on operation, the application of the laparoscope in hysteromyoma operation is increasingly wide, and the minimally invasive abdominal incision of the laparoscope is as small as 1cm, but the myoma is difficult to take out. The myoma is bored and is got to the commonly used myoma at present clinically, and the device only is fit for using at the great position in spaces such as pelvic cavity, needs the fixed myoma of forceps holder during the use, and then cuts the myoma, has the fixed not firm problem of easy slippage of forceps holder, and the device is because defect in the design easily causes the myoma tissue fracture of cutting, and can not take out this time the tissue of cutting. In addition, if the myoma is potentially malignant, iatrogenic tumors are easily scattered and planted when the device is used for taking the myoma. Therefore, for the myoma which is suspected of having malignant change, the myoma is usually loaded into a pick-up bag after being stripped in an operation, the pocket mouth of the pick-up bag is lifted out of an abdominal cavity through an abdominal wall incision, the space in the pick-up bag is narrow, the clamping and cutting of the myoma cannot be finished by a traditional myoma drills, the myoma can be taken only by adopting a manual clamping mode and a scalpel cutting mode at present, the clamping is difficult, the myoma tissue with the size of corn grains can be taken out at each time, the time for taking the myoma usually accounts for more than half of the time of the whole operation and the anesthesia, the efficiency is extremely low, the time and the physical strength are wasted, the physical and mental fatigue of an operator can be caused.

Therefore, compared with the traditional myoma drill, the device has the advantages of obvious advantages, simplicity in operation, higher efficiency, higher safety, wider application range and the like, and has a very wide application prospect.
(1) Solves the problem that the tool for taking myoma in the pick-up bag is lack
The abdominal cavity planting of present for avoiding potential malignant myoma is broadcast, it takes out to place it in picking up the thing bag, because the instrument lacks and lacks, can only adopt the forceps holder, the mode that the scalpel is cut is gone on, efficiency is extremely low, waste time and energy, increase operation time, anesthesia expense and operation risk, this device is because of utilizing the big tongs that is used for the forceps holder in the screw bit replaces traditional myoma to bore, the required space of operation has greatly been saved, consequently can carry out the efficient cutting in narrow and small picking up the thing bag, this kind of mode of getting the myoma also can popularize and apply to taking out of ordinary myoma.
(2) Greatly improving the myoma taking-out efficiency
Due to the characteristics that most myoma tissues are fragile, fragile and easy to break, the myoma tissues are often broken when the traditional myoma drill is used, so that the cut myoma tissues are also failed to be taken out (because the other end of the myoma tissues is still connected with the myoma mass body). The invention adopts the transmission of the rotary cutter, the spiral blade advances and cuts in the myoma in a spiral way, and the fracture of the myoma is not easy to cause because of no traction, and even if the myoma tissue is fractured, the fractured tissue is still positioned between the rotary cutter blades in the rotary drum and can be pushed out by the newly cut myoma tissue in the next cutting.
(3) Simple operation and wide application range
When the traditional myoma drill is used, the myoma needs to be fixed by clamping points and needs to be continuously adjusted. The method for fixing the myoma by the pick-up bag is adopted, the surrounding of the myoma is fixed, and the fixed position does not need to be adjusted repeatedly, so that the method is firmer and simpler; in addition, the invention can be applied to the taking out of the singly excavated myoma through an abdominal wall incision and the taking out of the uterus (combined myoma) through the vagina after the uterus is completely resected, thereby having wider application range and very wide prospect.
