Description

Circumcision

technical field

The invention relates to a medical device, in particular to a circumcision device with an injection hole.

Background technique

Prepuce or phimosis is one of the root causes of male urinary tract infections as well as sexually transmitted diseases. Excessive prepuce or phimosis can cause urinary tract infection and lead to chronic prostatitis, back pain, impotence and premature ejaculation and a series of symptoms. Therefore, removal of prepuce or phimosis is one of the best measures to prevent these diseases.

Removal of excessive prepuce or phimosis has been reformed several times since the early days of our country, but the operation will inevitably cause bleeding, pain, and hospitalization, especially circumcision is one of the traditional methods for treating phimosis, excessive foreskin and preventing its complications 1. It is a basic operation of male urology. The key points of the technique are the three major steps of excision of redundant foreskin, planing and bending to stop bleeding, and suturing the skin at the incision margin. The patient could not move around after the operation, and the pain was unbearable every time the medicine was changed, and he still had to endure great pain when the stitches were finally removed. In addition, incomplete ligation to stop bleeding would cause prepuce hematoma, which required reoperation. Although laser and high-frequency electrosurgical techniques have been used for circumcision, they only replace scissor cutting and coagulation of bleeding points. This treatment can leave the patient with tissue burns and a susceptibility to infection. And the cost of anti-infection is high. From the comparison of various provinces and cities, those who carry out laser circumcision generally use antibiotics for 5-7 days after surgery, plus oral antibiotics to prevent infection for 5-7 days, and the cost of laser circumcision is generally 150 -360 yuan, the whole treatment costs at least 1000-1500 yuan.

The prior art has proposed some circumcision solutions. These circumcision devices are simple and easy to operate, do not require surgery and sutures, have light pain, do not affect work and life, and have a short operation time. However, these circumcision devices are ubiquitous. The following defects:

2, the locking device of existing circumcision generally adopts screw rod to fix, and manual operation is very inconvenient, is extremely uncomfortable to the patient who intends to operate, has increased patient's sense of fear to operation, prolongs operation time.

3. The glans ring of the existing circumcision device has a ring-like structure, but the penis will inevitably become erect during the whole treatment process, so the structure of the glans ring diameter constant increases the discomfort of the patient. comfortability.

4. The existing circumcision device includes a fixed ring and an auxiliary ring. The glans of the penis is passed through the auxiliary ring, and the foreskin is placed between the auxiliary ring and the fixed ring and tied tightly to the auxiliary ring with a binding wire. In this way, when the penis expands, due to the weak elasticity of the binding rope and the small contact area with the foreskin, the binding rope and the foreskin will move relative to each other, resulting in the failure to completely block the blood flow, resulting in hematoma and affecting the surgical effect.

5. Continuing the circumcision device described in 4, in the actual operation process, because the binding operation is performed manually, it is often operated by experience according to the different habits of the operator, and its degree of tightness varies, resulting in The entire surgical operation process is not standardized, which affects the surgical effect.

6. There is a kind of circumcision device, the knife-edge junction of the two half-circles of the fixed ring is a right-angle structure, when in use, when the two half-circles are combined to tighten the penis, the knife-edge junction is easy to clamp the foreskin, so that the patient Very painful.
