Description

Prepuce ligation device that can prevent postoperative edema

technical field

The invention relates to a foreskin ligation device, which can not only cut off the overlong foreskin of the penis painlessly and without bleeding, but also can realize no edema after operation, and is an updated product of related medical equipment.

Background technique

In the prior art, the best marketable circumcision device (also known as a circumcision device) includes two parts, an outer ring and an inner ring; "Incision" (continuous clamping structure), this structure can achieve the purpose of painlessly and without bleeding to cut off the overlong penis foreskin, but the remaining foreskin after the operation is severely edematous, and the patient still needs a painful recovery period.

In addition, the inner ring of the prior art is in direct contact with the foreskin of the penis, and there is no measure to protect the frenulum. Therefore, during the operation, it is very easy to damage the frenulum between the inner surface of the foreskin of the penis and the glans. .

CN201160878Y discloses a high-end foreskin ligation device once developed by the inventor of the present application, which first adopts a C-shaped flexible outer ring and an outer edge structure of an inner ring with a soft outer ring and a harder inner ring, and its single-pole single-groove clamping structure Concaves were also formed on both sides to prevent the operation site from rubbing against the underwear, and its technical effect was clearly at the leading position in the industry at that time.

However, intraoperative safety issues and postoperative edema issues have always been hoped to be resolved, but have not really been resolved. In the prior art, the method of pouring liquid medicine and applying liquid medicine was once used, which not only made the structure of the foreskin ligation device complicated, the operation unchanged, but also the effect was not good.

The foreskin ligature device in the prior art does not take into account the impact on the foreskin frenum, which refers to a skinfold in the middle of the lower part of the penis that connects the glans and the penis body, and is mainly responsible for somatosensory and afferent The most important branch of the pudendal nerve, the dorsal nerve of the penis, is distributed to the back of the penis, mainly the skin of the glans penis, especially a small branch of which is specially distributed to the frenulum of the foreskin. Therefore, the frenulum of the foreskin is very sensitive to external stimuli. It is the most sensitive part of the penis and one of the most important erogenous zones for men. Its stretching force is strong, and it can be obviously elongated when the penis is erect, and it can be obviously shortened when the penis is flaccid.

According to the present invention, the inner edge of the outer ring adopts a non-continuous clamping structure. When interacting with the inner ring and clamping the foreskin, the foreskin is clamped at multiple points, and a movable clamping structure is formed between adjacent clamping parts. Channels that allow interstitial fluid and lymph fluid to pass through. When trying to remove the redundant foreskin, before a new circulation channel is established, the tissue fluid and lymph fluid at the resection site can be discharged from the body through this channel, thereby eliminating or reducing the postoperative edema caused by circumcision, thus overcoming the existing The edema complication caused by the complete blockage of interstitial fluid and lymphatic drainage/reflux channels by the continuous clamping structure in the technique.

According to the present invention, a protective sleeve is also used, which is also called a positioning piece. The distance can be greater than 8mm), when in-line circumcision, the positioning piece is located between the foreskin and the glans, when the foreskin is removed, the cylinder part of the positioning piece can provide sufficient protection for the frenulum, so it will not damage The tie can also protect the glans from accidental damage caused by surgical instruments.

In the prior art, the inner edges of the outer rings of all circumcision ligation devices are continuous incisions. Those skilled in the art have always mistakenly believed that only the continuous incision clamping structure can completely block the blood flow of the penis in the prepuce. flow. Such traditional technical bias has produced serious side effects, namely: the drainage of interstitial fluid and lymph fluid is completely blocked, and the resulting postoperative edema brings pain to the patient, and it is easy to cause edema complications.

The present invention finds another way, overcomes the prejudice of the above traditional technology, and adopts a series of clamping teeth with discontinuous structure, and a gap is provided between two adjacent clamping teeth.

According to the present invention, not only the problem of not being able to completely block the blood flow of the penis in the foreskin that has been worried about in the prior art does not appear, but also achieves an unexpected technical effect: reduce or even fundamentally eliminate the circumcision caused by postoperative edema.

Detailed ways

As shown in FIG. 1 , the outer ring 100 of the circumcision ligator according to the present invention is a C-shaped ring with a sufficiently soft but still sufficiently elastic opening, which has a single opening. During the operation, the opening can be conveniently enlarged, so that the inner space of the outer ring 100 becomes larger, and it is easier to fit on the inner ring. After the outer ring 100 is put on the inner ring, the inner space of the outer ring 100 will be automatically reduced, so that the opening tends to be closed.

The two sides of the opening of the outer ring 100 of the circumcision according to the present invention are respectively provided with connecting parts 101 . The connecting parts 101 on both sides are respectively provided with alignment devices 103 (for example, protrusions and positioning holes that cooperate with each other). The connecting parts 101 on both sides can be firmly connected together by a connecting device 102 (for example, a screw and a threaded connection pair).

According to the present invention, the two sides of the opening of the outer ring 100 of the foreskin ligation device are also respectively provided with clamping tooth alignment parts 104, and the clamping tooth alignment parts 104 can be half of the clamping teeth, which can prevent the outer ring 100 from The deflection along the axis direction of the outer ring 100 occurs after the closure, which can also ensure that the pain of the patient's flesh pinching does not occur at the opening.

A series of clamping teeth 105 are arranged on the inner edge of the outer ring 100 of the circumcision according to the present invention. In one example, the series of clamping teeth 105 are evenly distributed. Each clamping tooth 105 is provided with a clamping surface 106 . A gap 107 is provided between two adjacent clamping teeth 105 . The gap 107 is a channel that allows interstitial fluid and lymph fluid to pass through. After the blood supply of the redundant foreskin is blocked, the interstitial fluid and lymph fluid in the reserved part of the foreskin can still be discharged from the body through this channel, thereby eliminating or reducing postoperative edema caused by circumcision. On the contrary, in the prior art, the continuous "knife-edge" clamping structure completely blocks the drainage of interstitial fluid and lymph fluid, which easily causes edema complications.

The gap 107 between two adjacent clamping teeth 105 is generally between 0.5-2.5 mm. Even if the penile blood vessels in the gap 107 are not directly pressed by the clamping teeth 105, they will generally be between the two adjacent clamping teeth 105. Under the effect of clamping teeth 105, the blood flow is not smooth, and many of them are blocked from flowing. In special cases, if the blood flow cannot be completely blocked, one injection can be conveniently added to achieve the purpose of hemostasis.

As can be seen more clearly in FIG. 2 , the connecting parts 101 on both sides of the outer ring 100 of the circumcision according to the present invention are also provided with ear guards 108 and 109 respectively. The lugs 108, 109 can further prevent deflection along the axis of the outer ring 100 after the outer ring 100 is closed.

FIG. 2 shows the installed state of the circumcision according to the present invention, and FIG. 3 shows the disassembled state of the circumcision according to the present invention. The inner ring 200 is sleeved on the outer cylindrical surface of the protective sleeve 300 . A positioning stop is provided on the outer surface of the cylinder of the protective sleeve 300 , and the side surface 302 of the positioning stop is in close contact with the side surface 202 of the inner ring 200 in the installed state. Several positioning pins 301 extending along the axis of the protective sleeve 300 are also provided on the positioning stopper, and several positioning holes 201 are also provided on the side surface 202 of the inner ring 200 . Positions of the positioning pin 301 and the positioning hole 201 correspond to each other, and the positioning pin 301 can be inserted and fitted into the positioning hole 201 , so that the inner ring 200 is detachably installed on the protective sleeve 300 .

The outer edge of the inner ring 200 is provided with a groove 205 . The clamping teeth 105 of the inner edge of the outer ring 100 can be positioned in the grooves 205 in the mounted state.

Figure 4 shows the everted use of the circumcision according to the invention, while Figure 5 shows the inward use of the circumcision according to the invention.

In the everted usage of the circumcision according to the invention, as shown in FIG. 4 , the protective sleeve may not be used. The operation process is: the inner ring 16 is set on the outside of the penis 11, and placed between the coronal groove 13 and the root of the penis; The original inner surface of the foreskin 15 becomes exposed, and the part to be cut off of the foreskin 15 is aligned with the groove of the inner ring 16, and the frenulum 15 between the glans 12 and the root of the foreskin 15 in the coronal groove 13 is not easily Damage; put the outer ring 17 on the original inner surface of the exposed foreskin 15, and make the clamping teeth align with the groove of the inner ring 16; make the opening of the outer ring closed and connected together, after a few days, redundant The foreskin falls off on its own, and the remaining foreskin has no or no obvious edema.

In special cases, if there is a blood vessel on the foreskin just in the gap between adjacent clamped teeth, so that the blood flow cannot be completely blocked, one injection can be conveniently added to achieve the purpose of hemostasis.

In the built-in usage of the circumcision ligator according to the present invention, as shown in Figure 5, the operation process is: first put the protective sleeve 26 on the glans 22 of the penis 21, so that the protective sleeve 26 covers at least a part Coronal ditch 23 and frenulum 24; Inner ring 27 is enclosed within the outside of protective sleeve 26; Make the inner surface of foreskin 25 be placed on the outer edge of inner ring 27, the position that foreskin 25 intends to cut is aligned with the concave of inner ring 27 groove; the outer ring 28 is placed on the outer surface of the foreskin 25, and the clamping teeth are aligned with the groove of the inner ring 27; the opening of the outer ring is closed and connected together, and then the protective sleeve 26 can be removed. After a few days, the excess foreskin falls off on its own, and the remaining foreskin has no or no obvious edema. Due to the protective sleeve 26, the ligature 24 cannot be accidentally damaged during the operation.

Similarly, under special circumstances, if there is a blood vessel on the foreskin just in the gap between the adjacent clamped teeth, so that the blood flow cannot be completely blocked, one injection can be conveniently added to achieve the purpose of hemostasis.
