Detailed Description

While the present invention will be fully described with reference to the accompanying drawings, which contain preferred embodiments of the invention, it is to be understood that, prior to the description herein, one of ordinary skill in the art can modify the invention described herein while obtaining the technical effects of the invention. Therefore, it should be understood that the foregoing description is a broad disclosure to those skilled in the art and that the disclosure is not limited to the exemplary embodiments described herein.

Figures 1-6 illustrate a circumcision apparatus 100 according to a first embodiment of the present invention. The circumcision apparatus 100 of the present invention is used to remove an overlength foreskin or phimosis from a male patient, comprising: a barrel 11, a first end of the barrel 11 is configured to be inserted between the glans and the foreskin of a treated subject (male patient); a ring member 12 configured to be fitted over an outer surface of the cylinder 11; and a drive device 13 configured to drive the ring-shaped member 12. Barrel 11 includes blocking surface 111, ring 12 includes blocking ridges 121, and driving means 13 drives ring 12 to slide on the outer surface of barrel 11 so that blocking surface 111 is adjacent to blocking ridges 121 and clamps the foreskin therebetween.

In the circumcision apparatus 100 according to the first embodiment of the present invention, the outer diameter of the cylinder 11 is gradually increased from the second end (right end in fig. 1 and 2) to the first end (left end in fig. 1 and 2), and the blocking surface 111 is formed on the outer surface near the first end of the cylinder 11. Referring to fig. 4, the blocking ridge 121 is an annular protrusion integrally formed from the inner surface of the ring-shaped member 12, and the cross-section of the protrusion is substantially "V" shaped, but the end of the protrusion is not particularly sharp so as not to puncture the foreskin. As the driving means 13 drives the ring-shaped member 12 to slide on the outer surface of the cylinder 11 from the second end to the first end, the blocking ridges 121 of the ring-shaped member 12 gradually approach the outer surface of the cylinder 11, thereby gradually clamping the jacket wrapped on the outer surface of the first end of the cylinder 11. Thus, by blocking the blood flow in the foreskin with the smaller contact surface of the blocking ridge 121, the clamped foreskin will necrose when worn by the patient for about one week, thereby allowing the necrotic, lengthy foreskin to be removed. In another embodiment, the blocking ridges 121 are protrusions made of a soft material, such as a rubber material, provided on the inner surface of the ring 12, for example by means of adhesion.

In the circumcision apparatus 100 of the present invention, the blocking surface is provided with an elastic pad 14 made of, for example, rubber material, so that the prepuce can be slowly clamped, alleviating pain of male patients.

In the circumcision apparatus 100 of the first embodiment, the driving means 13 includes two link mechanisms oppositely disposed at both sides of the outside of the cylinder 11, each link mechanism including: a first link 132, a first end of the first link 132 being hinged to a second end of the cylinder 11 using a hinge member such as a pin; and a second link 131, a first end of the second link 131 being hinged to a second end of the first link 132 using a hinge member 133 such as a pin, a second end of the second link 131 being hinged to the ring 12, the blocking ridge 121 of the ring 12 being gradually brought close to the blocking surface on the cylinder 11 by, for example, manually driving the first end of the second link 131 and the second end of the first link 132 close to the outer surface of the cylinder 11.

Referring to fig. 4 and 6, in the first embodiment of the circumcision apparatus 100, the plane of the first end of the cylinder 11 and the plane of the tip of one of the "V" shaped protrusions are perpendicular to the axis of the cylinder 11. That is, when the barrel 11 is placed upright, the plane on which the first end of the barrel 11 is located is a horizontal plane. In a further embodiment, the walls of the barrel 11 other than the blocking surface 111 are provided with a plurality of vents to maintain the glans of a patient inserted in the barrel 11 in a ventilated environment during removal of an excessively long foreskin. The air permeable part 112 is a plurality of through holes each having a cross section of at least one of a trilateral shape, a quadrangular shape, a circular shape, and an elliptical shape.

The circumcision apparatus 100 of the first embodiment further comprises a holding means for holding the first link 132 and the second link 131 close to the outer surface of the cylinder 11. The holding means holds the first link 132 and the second link 131 by a snap connection structure. More specifically, referring to fig. 3, the holding means comprises: a receptacle 134 formed on the first link 132; and a latch 113 formed on an outer surface of the cylinder 11. The latch 113 has a plurality of projections 1131 projecting radially therefrom, the projections 1131 being distributed over two circumferences. When the first and

second links

132 and 131 are adjacent to the outer surface of the barrel 11, the latch 113 will be inserted into the receptacle 134 and a two-step lock can be achieved with two circumferential protrusions 1131 depending on the degree to which the sheath is clamped.

Fig. 7 is a sectional view of a circumcision apparatus 200 according to a second embodiment of the present invention. The circumcision instrument 200 of the second embodiment is different from the circumcision instrument 100 of the first embodiment in that the pins 223 in the holder of the circumcision instrument 200 have protrusions 2231 on one circumference, respectively, and the insertion holes 234 are provided on the first link 232. Thus, the circumcisor 200 of the second embodiment can only achieve one level of locking to the retention device. It will be appreciated that three or more locking stages of the retaining device may be achieved by providing projections on three or more circumferences of the bolt.

Fig. 8 is a schematic plan view of a circumcision apparatus 300 according to a third embodiment of the present invention. The circumcision apparatus 300 of the third embodiment is different from the circumcision apparatus 100 of the first embodiment in that the holding means of the circumcision apparatus 300 includes: a protrusion 334 formed on the second link 331; and a socket 313 formed on an outer surface of the cylinder 31. Two opposing arms 3131 are provided at the end of the socket 313. When the first and

second links

132 and 131 approach the outer surface of the cylinder 31, the arm 3131 grips the protrusion 334, thereby locking the socket 313 and the protrusion 334 together.

Fig. 9 is a schematic plan view of a circumcision apparatus 400 according to a fourth embodiment of the present invention. The circumcision apparatus 400 of the fourth embodiment differs from the circumcision apparatus 100 of the first embodiment in that the holding means of the circumcision apparatus 400 comprises: a spherical groove 434 formed on the second link 431; and an insertion part 413 formed on an outer surface of the cylinder 41. A spherical protrusion 4131 is provided at an end of the socket 413. When the first link 432 and the second link 431 approach the outer surface of the cylinder 41, the spherical protrusion 4131 is locked in a snap-fit manner in the spherical groove 434.

Fig. 10 is a schematic plan view of a circumcision apparatus 500 according to a fifth embodiment of the present invention. The circumcision apparatus 500 of the fifth embodiment is different from the circumcision apparatus 100 of the first embodiment in that the holding means of the circumcision apparatus 500 includes: a spherical protrusion 534 formed on the first link 532; and a socket part 513 formed to protrude from an outer surface of the cylinder 51, a spherical groove being formed on the socket part 513. When the first and

second links

532 and 531 approach the outer surface of the cylinder 51, the spherical protrusion 534 is locked in a snap-fit manner in the spherical groove.

In the circumcision apparatus according to the first and second embodiments, the latch of the holding means may be cut off by a tool such as scissors, thereby releasing the first link and the second link. In the circumcision apparatus of the third to fifth embodiments, at least one of the insertion part and the projection part of the holding means may be cut off using a tool such as scissors, thereby releasing the first link and the second link. The retention means is destroyed by this cutting operation, so that the circumcision instrument of the present invention can only be used once.

Fig. 11 is a sectional view showing a second fitting manner of the cylinder and the ring of the circumcision apparatus according to the first to fifth embodiments, in which the blocking ridges 121 are two annular protrusions integrally formed from the inner surface of the ring 12.

Figures 12-16 are plan schematic views of a circumcisor 600 according to a sixth embodiment of the present invention. The difference between the circumcision apparatus 600 of the sixth embodiment and the circumcision apparatus 300 of the third embodiment is that in the circumcision apparatus 600, the plane in which the tip of the "V" -shaped protrusion 121 on one circumference is located is at an acute angle to the axis of the cylinder 61, and the plane in which the first end (left end in fig. 12) of the cylinder 61 is located is parallel to the plane in which the tip of the "V" -shaped protrusion 121 is located. That is, the ring member 62 is obliquely disposed on the cylinder 61, and when the cylinder 61 is placed upright, the plane in which the first end of the cylinder 61 is located is an inclined plane. The cylinder body 61 with the inclined section is more in accordance with the shape of the coronary sulcus of the genitals of the male, so that the use is safer, and the operation effect is better.

Fig. 17 is a sectional view of the second fitting manner of the cylinder 61 and the ring member 62 of the circumcision apparatus 600 shown in fig. 12, wherein the blocking ridges 621 are two annular protrusions integrally formed from the inner surface of the ring member 62, and each annular protrusion has a substantially "V" shape in section. In another embodiment, the blocking ridge 621 is a protrusion made of a soft material such as a rubber material, for example, provided on the inner surface of the ring member 62 by bonding. It is to be understood that any of the holding devices described in the first to fifth embodiments may be applied to the circumcision instrument 600 of the sixth embodiment.

Figures 17-25 illustrate a circumcision apparatus 700 according to a seventh embodiment of the present invention. The prepuce circular cutter 700 includes: a barrel 71, a first end of said barrel 71 being configured to be inserted between the glans and the foreskin of a subject to be treated (male patient); a ring member 72 configured to be fitted over an outer surface of the cylinder 71; and a drive device 73 configured to drive the ring-shaped member 72. Referring to fig. 23, 24 and 25, a radially extending flange 714 is formed at the first end of the barrel 71, and an annular projection is formed extending from one side of the flange 714 to the second end of the barrel 71, the projection being generally "V" shaped in cross-section to form a blocking ridge 7141. In another embodiment, the blocking ridge 7141 is a protrusion of a soft material, such as a rubber material, for example, adhesively disposed on the flange 714. A blocking surface is formed on a first side of the ring 72 facing the blocking ridge 714. The driving means 73 drives the ring-shaped member 72 to slide on the outer surface of the cylinder 71 so that the blocking surface on the ring-shaped member 72 approaches the blocking ridge 7141 and clamps the foreskin therebetween. Further, an elastic pad 74 made of, for example, a rubber material is provided on the blocking surface to relieve pain of the male patient.

In the circumcision apparatus 700 of the seventh embodiment, the driving means 73 comprises: the drive ring 732 is provided with at least one pawl 7321 (see fig. 22) projecting radially inward on the inner surface of the drive ring 71; a plurality of ratchet teeth 712, said ratchet teeth 712 being formed on the outer surface of barrel 71 near the second end in a helical arrangement, each ratchet tooth 712 cooperating with a pawl 7321 to cause the drive ring 72 to rotate unidirectionally on the outer surface of barrel 71 and to move from the first end to the second end of barrel 71 during rotation; and a resilient member 731, such as a spring, fitted between the drive ring 732 and the ring 72 such that rotation of the drive ring 732 causes the resilient member 731 to bias the blocking surface on the ring 72 against the blocking ridge 7141 on the barrel 71 and clamp the foreskin therebetween.

In an alternative embodiment, the side of the flange 714 facing the second end of the barrel 71 forms a blocking surface and a blocking ridge is formed on the first side of the ring 72 facing the blocking surface.

Further, referring to fig. 18, 22 and 24, in the circumcision apparatus 700, a lock release hole 7322 formed near the pawl 7321 is provided on the drive ring 732, and the pawl 7321 is removed from the drive ring 732 by operating the lock release hole 7322, thereby releasing the engagement between the ratchet 712 and the pawl 7321. Specifically, a continuous or discontinuous unlocking hole 7322 is formed near the periphery of the drive ring 732 where the pawls 7321 are formed, but the portion where the pawls 7321 are formed is still kept connected to the drive ring 732 and it is ensured that the pawls 7321 can prevent the drive ring 732 from automatically rotating. Thus, a tool such as a screwdriver can be inserted into the unlocking hole 7322 and a small force is applied to remove the portion forming the pawl 7321 from the driving ring 732, so that the circumcision apparatus 700 can be used only once. Alternatively, long grooves are formed near the periphery of the drive ring 732 where the pawls 7321 are formed, thereby reducing the thickness of the portion where the pawls 7321 are connected to the drive ring 732, and unlocking holes 7322 are formed in the long grooves.

Figures 26 and 27 are cross-sectional views of a second mating arrangement of the barrel 71 and ring 82 of the circumcision apparatus 700, wherein the blocking ridges 7141 are two protrusions extending from the flange 714 to the second end of the barrel.

In the circumcision apparatus 700 of the seventh embodiment, the plane of the first end of the cylinder 71 and the plane of the blocking surface of the ring-shaped member 72 are perpendicular to the axis of the cylinder 71.

Since the second cylinder portion 912 of the cylinder 91 has a constant outer diameter, the driving device 93 of the circumcision apparatus 900 of the ninth embodiment, which includes the driving ring 932, the elastic member 931, the ratchet teeth 913 provided on the cylinder 91, and the pawls (not shown) provided on the driving ring 92, may be the same as the driving device of the circumcision apparatus 800 of the eighth embodiment, and a detailed description thereof will be omitted. The resilient member 931 is biased against the ring member 92 by rotating the drive ring 932, and as the outer diameter of the first barrel portion 911 gradually increases from the second barrel portion 912 to the first end of the barrel 91, this will gradually approach the blocking surface on the first barrel portion 911 of the barrel 91 during movement of the ring member 92, thereby clamping the jacket between the blocking ridge 921 of the ring member 92 and the resilient pad 94 on the blocking surface, as shown in fig. 38.

Figures 39-41 are cross-sectional views of a second mating arrangement of the barrel 91 and ring 92 of the circumcision apparatus 900, wherein the blocking ridges 921 are two protrusions extending inwardly from the ring 92.

In the circumcision apparatus 900 according to the ninth embodiment, the plane where the first end of the cylinder 91 is located and the plane where the blocking surface of the ring-shaped member 92 is located are parallel to each other and the included angle with the axis of the cylinder 91 is acute. In addition, as shown in fig. 34, 38 and 41, the ring member 92 is provided with a balance section 921 extending toward the second end of the cylinder 91, and the surface of the balance section 921 in contact with the elastic member 931 is perpendicular to the axis of the cylinder 91. The balancing portion 921 may be formed extending from the ring member 92, and have a right triangle shape, or a right trapezoid shape in one plan view. Since the balancing portion 921 has a portion that moves against the surface of the cylinder 91, the ring member 92 can be maintained in a constant inclined posture.

In an alternative embodiment of the circumcision apparatus 900, the plane of the first end of the barrel 92 and the plane of the tip of one of the "V" shaped projections 921 are both perpendicular to the axis of the barrel 92.
