Description

A quasi-markless circumcision component and a quasi-markless circumcision method

technical field

The invention relates to the field of medical devices, in particular to a quasi-scarless circumcision component and a quasi-scarce circumcision method.

Background technique

The incidence of redundant prepuce and phimosis is extremely high in Asian countries. The hazards of redundant prepuce: 1. The foreskin covers the glans for a long time, making the glans very sensitive. When having sex, the glans is very sensitive and can easily cause premature ejaculation; 2. 1. It is easy to cause male infertility. Prostatitis caused by smegma infection can reduce sperm motility and semen viscosity, which can cause infertility; 3. When the foreskin is too long, it is easy to produce "smegma". Foreskin smegma is suitable for bacterial growth, so it can cause inflammation of the glans and foreskin; 4. Long foreskin is the main source and important factor leading to repeated cross-infection of male and female reproductive diseases; 5. Bacteria, viruses, and exfoliated epithelial cells in the foreskin of the penis for a long time Stimulation such as dirt, will increase the incidence of penile cancer. Therefore, there is a popular saying in urology: the foreskin must be cut sooner or later.

In my country's traditional circumcision, manual surgery has the following disadvantages: 1. It takes a long time, and often the operation cannot be completed within the action time of local anesthetics. It is often done in the second half of the operation. Anesthesia for surgery is quite painful, so it brings a lot of pain to the patient. 2. There is a lot of bleeding. Traditional circumcision needs to remove part of the inner plate of the foreskin. The inner plate contains a large number of blood vessels and lymphatic vessels. The bleeding point needs to be ligated with conventional silk thread to stop bleeding. It cannot be absorbed, which will bring a lot of pain to patients in the future, so many doctors will choose to use electrocautery to stop bleeding, but the electric coagulation of electrocautery will damage more capillary lymphatic vessels, and the foreskin water will be particularly serious after operation , causing great pain to the patient. 3. Since the foreskin at the glans is quite sensitive, the pain when removing stitches is even higher than that of surgery. In order to relieve the pain of patients, some hospitals will give local anesthesia when removing stitches, so many hospitals will use more expensive absorbable stitches.

In recent years, many staplers have appeared in clinical work, and have been widely used in clinical practice, and have also brought benefits to patients. The advantages are: 1. The operation time is greatly shortened, and ordinary circumcision requires about 40 minutes. -60 minutes, while using a stapler, the operation time is shortened to 10-20 minutes, which can save more than half of the time; 2. The amount of blood loss is very small, only a few milliliters, and even most of the blood loss in operations is less than 1 milliliter. 3. Reduce the pain of the patient, shorten the operation time, and the patient can strive to go to the ward or go home to rest before the anesthesia passes. 4. There is no need to remove the stitches. The titanium alloy nails will start to fall off in about 1 week after the operation and will finish falling off in about 2 weeks.

But even so, there are still many shortcomings that need to be improved in clinical practice: 1. During circumcision, the current stapler will remove most of the inner plate that originally surrounded the penis. An important source of pleasure in the middle, removing this part of the inner plate will reduce the pleasure of men; 2. When cutting the foreskin, the head of the foreskin needs to be tied to the fixer. The glans is wrapped in the foreskin, and the foreskin and glans cannot be seen clearly. It is often not easy to grasp the length of resection; 3. After surgery, there will usually be a lot of scars left on the foreskin next to the glans. Although the scars are neater than traditional manual circumcision, some patients have long-lasting scars after surgery. Some of them will swell after erection or sexual life, and even hyperplasia of subcutaneous fibrous tissue, which brings a lot of pain to the patients; 4. Since the stapler will cut off the part of the frenulum that is closely connected to the glans, the frenulum is rich in blood supply, especially It is the junction of the glans and foreskin, which is often the main bleeding point of the operation, and there is often active bleeding; 5. Removal of part of the inner plate of the foreskin damages some capillary lymphatic vessels, resulting in blocked lymphatic return and obvious swelling.

Contents of the invention

The purpose of the present invention is to provide a quasi-scarless circumcision assembly and quasi-scarce circumcision method, which completely overturns the previous surgical methods of circumcision, and can retain the original inner plate of the outer foreskin of the glans, so that the glans The foreskin is kept in its original ecology, and the circumcision effect is quasi-scarless.

The technical solution adopted by the present invention to solve the technical problems is: a quasi-markless circumcision assembly, comprising an outer cutting sleeve and an inner fixing sleeve, the outer cutting sleeve is placed on the inner fixing sleeve, and is connected with the inner fixing sleeve. The sleeve is clamped, and the lower end of the inner fixing sleeve has an outwardly extending annular retaining edge, and a blade pad is arranged inside the annular retaining edge, and a threaded part is arranged at the upper end of the inner fixing sleeve, and a set of Positioning protrusions, the end of the inner fixing sleeve close to the annular retaining edge is formed with a binding groove around the circumferential direction of its outer wall;

The outer cutting sleeve comprises an outer sleeve, an annular blade and an annular nail bin, the annular nail bin is fixed on the lower end of the outer sleeve, a plurality of pusher rods are uniformly distributed along the circumferential direction of the annular blade outer wall, and the inner wall of the annular nail seat is provided with The nail cartridge that is slidably matched with the pusher rod, the inner wall of the annular blade is also provided with a positioning groove that matches the positioning protrusion, and the outer wall of the annular blade is also fixed with a connecting shaft, and a connecting shaft is arranged between the connecting shaft and the pusher rod. There is a connecting spring, and a sliding groove is opened on the side wall of the outer casing, and the connecting shaft passes through the sliding groove and is connected with the lifting drive structure outside the outer casing;

The quasi-markless circumcision assembly also includes a nut, and when the inner fixing sleeve protrudes from the outer cutting sleeve, the nut is threadedly connected with the threaded part.

As a preferred structure of the present invention, the lifting drive structure includes a fixed handle and a lifting handle arranged outside the outer casing, one end of the lifting handle is bent downward and is movably connected to the connecting shaft through a connecting plate, and the bending part of the lifting handle is connected to the The outer walls of the outer sleeve are hinged.

Preferably, the front end of the lifting handle can also be provided with a driving part with an arc-shaped groove, and the rear end of the lifting handle is provided with an anti-slip protrusion; a safety block is also provided between the fixed handle and the lifting handle.

The present invention also provides a kind of quasi-markless circumcision method, comprising the following steps:

(1) Firstly, the skin of the perineum is prepared, disinfected, a hole towel is spread, and the root of the penis is partially infiltrated with anesthesia;

(2) Put the internal fixation sleeve on the root of the penis, and wrap the wrinkled outer foreskin on the ring-shaped rim, and fix the wrinkled outer foreskin with sutures or ties Tie on the wire binding groove;

(3) Then put the outer annular cutting sleeve on the inner fixing sleeve, the positioning protrusion matches the positioning groove, and fix the inner fixing sleeve and the outer annular cutting sleeve together with a nut;

(4) Remove the safety block, hold the lifting handle upwards, drive the connecting plate, and push the annular blade down through the connecting shaft. When the annular blade collides with the blade pad in the annular retaining edge, the wrinkled foreskin The tissue is cut off, and at the same time, the staple pusher fixed on the circular blade pushes out the staples in the staple bin, and sutures the foreskin incision;

(5) After 10-15 seconds, unscrew the nut, remove the outer annular cutting sleeve and internal fixation sleeve as a whole, and aseptically bandage.

The beneficial effects of the present invention are:

(1) The present invention can be used to remove the outer plate of the foreskin located at the root of the penis, that is, the penis, the scrotum and the abdominal wall. Because the outer plate of the foreskin is very thin, there are few large blood vessels, nerves and lymphatic capillaries, which makes the foreskin more difficult after surgery. The swelling of the pubic hair is greatly reduced; secondly, the inner plate around the glans with a wide distribution of nerves is retained, so that the quality of sexual life after surgery can be guaranteed. Scars; at the root of the penis, the penile frenulum migrates into a "scar" line that protrudes from the skin surface. The blood vessels and nerves contained in it are much less than those at the lower end of the glans, and the amount of postoperative bleeding is less.

(2) During operation, since both the internal fixation sleeve and the external cutting sleeve are placed on the penis, and the head of the penis protrudes from the internal fixation sleeve, when fixing the outer plate of the foreskin, the length of the foreskin that needs to be removed can be visually observed; safety high sex.
