Description

External-turning prepuce shaping water jet scalpel

Technical Field

The utility model relates to an outward turning type foreskin plastic water jet scalpel, which belongs to the technical field of medical instruments.

Background

The redundant prepuce and phimosis both seriously affect the physical and mental health and the sexual life quality of men, and cause gynecological diseases of sexual partners to a certain extent, and are seriously easy to cause cervical cancer. The proportion of circumcision worldwide has increased due to the push of a large number of medical research efforts in recent years. In the prior art, prepuce overlength and phimosis are mainly treated by operations. There are currently three main surgical approaches. The first is conventional circumcision. The doctor cuts off redundant foreskin through scissors, then thoroughly stanchs, and is interrupted to sew up, and its shortcoming is mainly that the foreskin has certain elasticity, therefore when the doctor cuts the foreskin, the incision is different in size, and is extremely out of order, leads to the postoperative less pleasing to the eye, and consuming time longer. The second method is to use a disposable prepuce stapler (circular). Its advantages are short operation time (about 5 min), no bleeding, and high defect: the pressure dressing can not be carried out after the operation, so that edema with different degrees can appear in all patients after the operation, and partial patients even need the second-stage operation after the operation to excise the edema tissues. The second step is as follows: the patient can not wear the trousers after operation because the annular prepuce anastomat has large volume and can not be taken down immediately after the operation, and the patient generally needs to be sleeved on the penis for 7 to 8 days to take down the annular prepuce anastomat. And thirdly: pain and discomfort, especially in the morning, combined with edema, afflicting many patients; when the ring is taken 7 days after the operation again, the foreskin is scabbed and is tightly attached to the inner ring, so that the patient can feel severe pain and discomfort because the inner ring needs to be pried down forcibly when the inner ring is detached. Finally, infection is caused, and because the volume of the outer ring and the inner ring of the device is large, the incision is inconvenient to pack, the wound is exposed outside after the operation, so that the wound is easy to be infected, and the wound healing is influenced. The third method is a disposable prepuce stapler (staple type). Its advantages are short operation time (5 min), binding after operation and no influence on wearing trousers. But the defect is also obvious, firstly, the bleeding is easy to occur, and once a certain gap is formed between the nails and the fractured blood vessel is arranged in the gap, the hematoma is easy to form after the operation seriously and needs to be removed after the operation again; secondly, pain and discomfort occur, the steel nail structure is similar to a staple mode and is anastomosed, so that the situation that the nail is not reversely folded occurs at a certain probability, once the situation occurs, the nail foot which is not reversely folded is directly pricked in penis meat, once a patient is bristled in the morning, the nail meat is formed, and the patient can generate severe pain and even secondary bleeding; finally, the nail is removed, so that a lot of patients are difficult to naturally remove the nail, doctors need to come to a hospital to assist in removing the nail, at the moment, the doctors can only pull out the nail violently, pain and discomfort are caused, and the nail hole bleeding is not continuous. Therefore, there is a need in the art to overcome the drawbacks of the prior art and to obtain a better technical solution for cutting foreskin.

The water jet cutter is a device for cold cutting by using high-pressure water jet, the pressure of the medical water jet cutter is far lower than that of the industrial water jet cutter, but the working principle of the medical water jet cutter is similar to that of the industrial water jet cutter, namely, sterile normal saline is pumped out by using a high-pressure pump, reaches an operation handle through a conduit, and is sprayed out through a tiny nozzle on the handle to generate local high pressure so as to cut human tissues. The medical water jet scalpel has the greatest characteristics that tissue structures with different strengths and toughness are selectively cut and finely separated, so that specific tissues are protected to the greatest extent, the medical water jet scalpel has the advantages of clear visual field and less bleeding, and meanwhile, as the water jet scalpel does not generate heat energy, thermal damage of other surgical instruments such as a high-frequency electrotome, a laser, an ultrasonic scalpel and the like to surrounding tissues is avoided. In recent years, medical water jet scalpel is widely applied to clinical special departments such as hepatobiliary surgery, neurosurgery, rectal surgery, otorhinolaryngology head and neck surgery and the like, and laparoscopic surgery by virtue of unique advantages.
