Description
Technical Field
The invention relates to a disposable foreskin cutting anastomat, which belongs to medical equipment and is particularly suitable for foreskin cutting and anastomosis operations of men due to overlong foreskin or phimosis.
Background
Many men have prepuce inflammation, penis development influence, penis inflammation and even premature ejaculation caused by canceration (85% -95% of patients with penis cancer are phimosis or prepuce overlength) due to the condition that the prepuce is overlength or phimosis. More and more men (children, young, middle-aged and elderly) are beginning to receive circumcision, growing year by year. At present, the main means of the prepuce operation is the traditional circumcision operation, the laser operation or the self-shedding of the prepuce due to ischemia by means of some small instruments. Foreskin scorching often occurs with laser surgery. The traditional circular cutting operation and the operation with the help of small instruments have high requirements on clinical experience of doctors, complicated operation, excessive bleeding caused by slight carelessness, increased pain of patients, prolonged operation time, low operation success rate, uneven and smooth incision, unsightly wound suturing, hematoma after operation, and troublesome dressing change and stitch removal after operation.
The back end of the tortoise head cover of the existing disposable foreskin cutting anastomat is provided with a connecting long rod, so that the face of a doctor is easily stabbed in the operation process, and the smooth operation is not facilitated. In addition, the existing disposable prepuce cutting anastomat is operated by two handles, and the handles of the instrument are held during operation, so that the anastomat is easy to fire with little carelessness. In an unfired state, the spans of the two handles are relatively large, the two handles need to be relatively large, and the operation is inconvenient.
