DESCRIPTION:
BRIEF SUMMARY
This invention relates to a circumcision clamp.
Circumcision involves surgical removal of the foreskin or prepuce of the penis. Although it is a minor operation it still too often becomes time-consuming and bloody.
The common practice, generally, in carrying out circumcision, even today, is to use surgical scissors to cut the foreskin. The trimming obtain is usually not only crude and rough but also causes bleeding and needs sutures to be applied to the cut edges. Generally, sterilised gauze and dressing are also applied and sometimes antibiotics may have to be prescribed to prevent infection. Also, undue or unusual loss of tissue due to simple excessive excision, sometimes amounting to accidental amputation of the penis have been mentioned in the literature.
In the prior art, there is a number of instruments known for performing circumcision operations. For practical purposes, many are complex to operate and have an undesirably large number of parts which are either detached from each other or need several auxiliary instruments in operation.
A number of such instruments involve clamping. This is attained by tightening a clamp at the desired position on the prepuce by a screw mechanism. In such screw devices the screw has to be manipulated or turned gradually until occlusion of the prepuce has been achieved. This, therefore, does not achieve an "instant occlusion" at the site of clamping. Also, soon after the circumcision has been performed, the clamp is dismantled and removed. The exposed cut edges generally need to be sutured and aseptic dressing has to be applied. The wound has to be closely watched for infection, bleeding and oozing for the next few days.
Some of the prior instruments involve clamping by applying a tight ligature to a bell shaped device which is fitted over the glans. The foreskin is stretched over this and a ligature is applied at the base. The distal foreskin is then excised and the base of the device is left in situ until it drops off in a few days. Complications such as bleeding, infection and oozing have also been reported.
Some circumcision tools involve using a ring-clamp. As the penis is almost always in a naturally flaccid state because of apprehension and fear whenever a circumcision is performed, the ring-clamp being used to clamp the foreskin may just fit the flaccid penis. A narrow ring-clamp does sometimes pose problems when the penis has an erection. Such erections generally occur in the mornings. During an erection, as the circumference and length of the penis increases, such a ring-clamp may become tight and cause some degree of constriction at the operated site. As a result, such erections present a major problem after operation and cause some discomfort and in some cases considerable pain, at the operated site. Also in cases where sutures have been applied, such erections also put tension on the suture line and cause considerable pain.
The present invention is an improvement and overcomes the above noted circumcision problems associated with heretofore available clamps. It is designed to allow for instant clamping of the foreskin at the desired level. Such clamping produces an instant, total and complete occlusion of the blood and nerve supply to the foreskin which is distal to the site of occlusion. As a result, minimal pain is felt and there is hardly any lingering pain after the circumcision has been performed. It also diminishes the fear, anxiety and apprehension associated with circumcision. Complete haemostasis and infection prevention, until the operated site has healed are other benefits derived from this invention. The design also prevents constriction at the operated site when the penis has an erection.
The instrument is of a simple design and is plastic based. It is pre-sterilised and is individually packed in a sterile packing. It is meant for single use only and is entirely disposed of after use.
Since each circumcision tool is supplied in a sealed sterile packing and is meant for single use only, the need, therefore, to predetermine the right size of th
