The present invention relates to surgical devices, particularly to a built-in washer circumcision device and a valgus washer circumcision device
Refer to the built-in washer circumcision device and a valgus washer circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.
Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis process are performed separately, the operation time is prolonged, and the patient's panic is exacerbated.
A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.
Then, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, the suturing nail/U-nail used in the circumcision device in the prior art is generally made of metal. After being tapped into the prepuce of a patient during a surgical operation, the metal U-nail will be in direct contact with the skin, which is likely to cause skin/tissue allergy, even infection, of the patient. In addition, if the U-nail is in direct contact with the skin and tissue of the patient, the possibility that the U-nail inserts into the tissue too deep during the surgery is very high, resulting in damages. Moreover, the U-nail may drop off in a postoperative period as friction between the metal U-nail and the skin/tissue is smaller, which may cause the failure of the surgery due to dropping off of the nail.
Refer to the built-in washer circumcision device and a valgus washer circumcision device. For the above problems in the prior art, an object of the present invention is to provide a washer circumcision device, and particularly relates to a built-in washer circumcision device and a valgus washer circumcision device. By arranging one or more washers, a U-nail will not be in direct contact with the skin or tissue after being tapped out and fixed to prepuce in a chamfered manner, so that allergy, infection, and too deep tapping of the nail into the tissue or dropping off of the nail are avoided. The specific technical solutions are as follows.
A built-in washer circumcision device comprises a circumcision cover, a comprehensive cover and a first washer and/or a second washer, wherein the comprehensive cover is provided with a U-nail groove; the first washer is arranged in the U-nail groove along the longitudinal outer side of the comprehensive cover; a U-nail seat corresponding to the U-nail groove is arranged on the circumcision cover; and the second washer is arranged on the U-nail seat.
Further, a first ring-shaped groove is formed at the end of the comprehensive cover towards the circumcision cover, and is located outside the U-nail groove; and the first washer is arranged in the first ring-shaped groove.
Further, the first washer is slightly wider than the first ring-shaped groove, so that the first washer is elastically clamped in the first ring-shaped groove.
Further, the first washer has a ring and a protrusion located on the bottom surface of the ring; a second ring-shaped groove is also formed at the end of the comprehensive cover towards the circumcision cover, and is located in the periphery of the first ring-shaped groove; and the protrusion is configured to be clamped in the second ring-shaped groove.
Further, a third ring-shaped groove is formed in the U-nail seat towards the U-nail groove; and the second washer is arranged in the third ring-shaped groove.
Further, the comprehensive cover is provided with a circumcision knife; and a third washer is arranged at the end of the circumcision cover towards the comprehensive cover and corresponds to an anvil of the circumcision knife.
Further, the third washer has a first lateral portion surrounding the anvil, a longitudinal portion perpendicular to the first lateral portion, and a second lateral portion surrounding the U-nail seat.
Further, the first, second and/or third washers are rubber washer(s) and/or silicone washer(s). Further, the built-in circumcision device may be a flat-head-type or inclined-head-type built-in circumcision device.
Further, the first washer is a U-nail backing ring; a protruding positioning ring is arranged on one surface of the U-nail backing ring; a placing groove is formed on the comprehensive cover in the periphery of the first ring-shaped groove; and the positioning ring and the placing groove may be clamped or elastically cooperate with each other to fix the U-nail backing ring.
Both the first and second washers are located on the same axis as a U-nail.
The present invention further provides a valgus washer circumcision device, comprising: an inner comprehensive cover, an inner ring and a first washer and/or a second washer, wherein the inner comprehensive cover and the inner ring correspond to each other vertically; the first washer is arranged at the end of the inner ring towards the inner comprehensive cover; and/or a U-nail groove is formed at the outer edge of the inner comprehensive cover; and the second washer is arranged at the top of the U-nail groove.
Further, both the first and second washers are located on the same axis as a U-nail in the U-nail groove.
Further, a first ring-shaped groove is formed on the lower end surface of the inner ring towards the inner comprehensive cover; and the first washer is arranged in the first ring-shaped groove.
Further, the first washer is slightly wider than the first ring-shaped groove, so that the first washer is elastically clamped in the first ring-shaped groove.
Further, the second washer is arranged outside the U-nail groove, and is located above the opening of the groove.
Further, the second washer has a ring and a protrusion located on the bottom surface of the ring; and the protrusion is configured to be clamped in the U-nail groove.
Further, the second washer is arranged at the top inside the U-nail groove.
Further, the second washer is slightly wider than the U-nail groove, so that the second washer is elastically clamped in the U-nail groove.
Further, a second ring-shaped groove whose top is flush with that of the inner comprehensive cover is formed between the inner edge of the inner comprehensive cover and the U-nail groove; and the second washer is arranged in the second ring-shaped groove.
Further, the valgus washer circumcision device also comprises an upper cover and a lower cover which correspond to each other vertically; the inner comprehensive cover is arranged in the lower cover; the inner ring is arranged in the upper cover; and the inner comprehensive cover and the inner ring correspond to each other vertically.
Compared with the prior art, the present invention provides one or more washer structures. During a circumcision operation, after being tapped out from a U-nail chamber, the U-nail first passes through the washer, so that the main surface of the U-nail will not contact the prepuce skin or tissue after being nailed with the prepuce tissue.
Further, if a plurality of washers is arranged, after being tapped out from a U-nail chamber, the U-nail first passes through the first washer and prepuce tissue sequentially and then the second washer before being in contact with the U-nail seat, and then is clamped in the U-nail seat in a chamfered manner, such that a sandwiched structure comprising the washer, the prepuce and the other washer is formed in the clamped U-nail. Therefore, the possibility that the prepuce tissue is in contact with the metal U-nail is reduced to the greatest extent, so that allergy, infection, too deep tapping of the U-nail into the tissue or dropping off of the U-nail are avoided.
