Description

prepuce cosmetic surgery assistor

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to prepuce cosmetic surgery assistor.

background

redundant prepuce or phimosis are common conditions of urology; the diseases such as urethra infection, prostatitis and the like are easily caused by overlong prepuce or phimosis, and the prepuce is also one of the transmission channels of venereal diseases; thus, excision of an excessively long foreskin or phimosis is one of the methods for preventing such diseases.

circumcision refers to the removal of excess foreskin from the penis to expose the glans penis, and is an effective treatment for phimosis, redundant foreskin and its complications. Circumcision has many methods, and at present, foreskin excision is realized by using a lantern ring method.
