In the process of performing the foreskin plastic cutting operation, the cutter head used by the prior foreskin plastic cutter is difficult to realize thorough hemostasis and pressurization binding in the operation. The application provides a flower knife for a prepuce cutting operation, which can thoroughly stop bleeding in the operation and can be used for pressing and binding by doctors, but a processing die special for the prepuce cutting flower knife is lacking currently, and therefore, the application provides a forming die of the flower knife and a manufacturing method of the flower knife.

The application will be described in detail below with reference to the drawings in connection with embodiments.

Example 1

The flower knife forming die is used for manufacturing flower knives, and the flower knives are used for cutting foreskin and performing foreskin plastic surgery. With reference to fig. 1, the flower knife has a plurality of flower knife protrusions along the radial direction thereof, and the long side direction of the flower knife protrusions is the same as the radial direction of the flower knife. The flower knife bulges are sequentially connected to form a closed loop, flower knife grooves are formed between the adjacent flower knife bulges, and the flower knife bulges and the flower knife grooves enable the cut foreskin to form a foreskin incision with the bulges and the grooves which are sequentially connected.

Referring to fig. 2 and 3, the flower-knife forming die of the present embodiment includes: a first body 10, a plurality of sliders 20 and a flower cutter core die 30. The first body 10 adopts a structure such as a cylinder or a prism, a plurality of slide ways 11 are provided on the first body 10, the sliding piece 20 can slide along the slide ways 11, the sliding piece 20 comprises an embedded portion 21, and the embedded portion 21 belongs to one end of the sliding piece 20, which is close to the flower knife core die 30. The said flower knife mandrel 30 has several embedded grooves 31, when the sliding piece 20 is pressed, the sliding piece 20 inserts its embedded part 21 into the said embedded groove 31 along the slideway 11.

When the flower knife is manufactured, the annular metal pipe which is used for manufacturing the flower knife after being processed is sleeved on the flower knife core mould 30, a certain pressure is applied to the sliding piece 20, the sliding piece 20 slides along the slideway 11, and the embedded part 21 is pressed into the embedded groove 31 matched with the sliding piece. The annular metal pipe for the manufacture of the flower cutter, such as a seamless steel pipe, is sleeved on the flower cutter core mold 30, and the embedded part 21 of the sliding piece 20 is separated from the flower cutter core mold 30, so that the embedded part 21 and the flower cutter core mold 30 cannot be in direct contact, the seamless steel pipe is extruded and molded under the cooperation of the embedded part 21 and the flower cutter core mold 30, and a plurality of bulges and grooves are formed on the extruded seamless steel pipe along the radial direction of the seamless steel pipe, namely, the extruded seamless steel pipe has the same structure as at least part of the flower cutter core mold 30.

As a further embodiment, referring to fig. 4 and 5, the insert grooves 31 are provided in the radial direction of the flower-cutter core die 30, and the insert grooves 31 are uniformly and equidistantly distributed in the circumferential direction of the flower-cutter core die 30. The structure of the embedded grooves 31 of the flower-cutter core mould 30 directly determines the structure for manufacturing the flower-cutter, and the embedded grooves 31 are uniformly and equidistantly distributed in the circumferential direction of the flower-cutter core mould 30, so that the strength structure of the extruded seamless steel pipe is further improved. That is, for the seamless steel pipe with the same wall thickness, the strength is weaker than that of the seamless steel pipe after being extruded and formed, based on the technical effect, in the case that the length and the maximum outer diameter of the annular cutter head used for prepuce cutting in the prior art are the same, the annular cutter head used for prepuce cutting needs larger wall thickness to ensure the strength of the cutter head per se relative to the seamless steel pipe extruded and formed by the flower cutter forming die. The flower knife manufactured by the flower knife forming die can meet the strong requirement by selecting a seamless steel tube with thinner wall thickness.

As a further embodiment, in combination with fig. 5 and 6, the shape of the single insert groove 31 is triangular, rectangular, parabolic, or the like, the insert grooves 31 on the flower-knife core mold 30 are sequentially connected in the circumferential direction of the flower-knife core mold 30, and after the sequentially connected insert grooves 31 are unfolded, the shape of the insert groove 31 may be a sinusoidal pattern, a zigzag shape, a great wall shape, or the like. The structure of the insert portion 21 of the corresponding slider 20 changes following the structure of the insert groove 31 of the flower cutter core die 30.

Different types of embedding grooves 31 and structures of the embedding parts 21 are selected, and corresponding flower cutters with corresponding structures can be obtained, so that in the prepuce cutting operation by using the flower cutters, different types of prepuce incisions can be formed according to the selection of patients, the healed prepuce incisions form scars with corresponding shapes, and the friction force is further increased.

Example 2

The forming die of the flower knife of the present embodiment is further improved on the basis of the above embodiment. Referring to fig. 7 to 9, the forming mold of the flower knife includes a second body 40, the second body 40 is slidably connected with the slider 20, and the insert portion 21 is inserted into the insert groove 31 by pressing down the second body 40.

The split type design is adopted to first body 10, slider 20 and second body 40, adopts split type design's aim at, and harm appears in single slider 20, can carry out the targeted change, also can carry out relative change when same second body 40 appears damaging to make the shaping mould maintenance of flower sword more convenient.

The second body 40 is at least partially located at the upper side of the sliding member 20, and the sliding member 20 is driven to slide on the slideway 11 by pressing the second body 40. Specifically, the second body 40 includes a second inner wall 41, and referring to fig. 10, the slider 20 includes a sliding sidewall 22, and the second inner wall 41 is at least partially in contact with the sliding sidewall 22, and the second inner wall 41 is configured to insert the insert portion 21 into the insert groove 31 of the flower-cutter core die 30 by driving the sliding sidewall 22.

The second inner wall 41 and the sliding side wall 22 both adopt inclined structures, and the contact positions of the second inner wall 41 and the sliding side wall 22 are two surfaces which can be designed to be completely attached, so that the pressing driving process of the second body 40 on the sliding piece 20 is smoother. As a further embodiment, when the second body 40 is pressed down to the limit position, that is, the insert portion 21 of the slider 20 is completely inserted into the insert groove 31 of the flower-cutter core die 20, a force of interference is formed between the flower-cutter core die 30 and the slider 20, so that the slider 20 cannot continue to slide toward the flower-cutter core die 30 along the slide 11. At this time, the sliding side walls 22 are completely adhered to the second inner wall 41.

As a further embodiment, referring to fig. 2, the first body 10 includes a plurality of limiting protrusions 12, the plurality of limiting protrusions 12 are distributed in an annular shape around the center of the first body 10 at equal intervals, a sliding track 11 is formed between adjacent limiting protrusions 12, and the sliding member 20 slides in the sliding track 11 relative to the limiting protrusions 12.

The stability of the sliding member 20 during sliding is further improved by the limit bump 12. If the slide 11 provided on the first body 10 is a common slide rail, the slide 20 is easily separated from the preset slide 11 due to the large extrusion force applied to the slide 20 when the seamless steel pipe is molded by extrusion, so that the damage of the forming die of the flower knife and the failure of the processing of the flower knife are caused. The utility model solves the technical problem that the utility model can ensure that the sliding piece 20 is not separated from the plane direction of the slideway 11 unless the limit bump 12 breaks and is separated from the first body 10.

Referring to fig. 11, the limiting bump 12 includes a limiting sidewall 120, and the second inner wall 41 is at least partially parallel to the limiting sidewall 120, so that the second inner wall 41 is attached to the limiting sidewall 120 when the insert portion 21 is inserted into the insert groove 31 of the flower-knife core die 30. The limiting side wall 120 plays a limiting role on the second body 40, when the sliding piece 20 cannot slide along the slideway 11 towards the flower knife core die 30, the extrusion of the second body 40 to the sliding piece 20 also reaches a limiting value, at this time, the second inner wall 41 is attached to the limiting side wall 120, and the limiting side wall 120 distributes the pressure of the second body to the sliding piece 20, so that the sliding piece 20 is protected.

Example 3

In embodiment 2, the limiting bump 12 ensures the stability of the sliding member 20 on the plane where the slideway is located, but the sliding member 20 still has the risk of being broken out from the upper portion of the limiting bump 12, in order to solve this technical problem, a baffle (not shown in the figure) may be disposed on the upper side of the limiting bump 12, so that the limiting bump 12 forms a circumferentially closed cavity, and the sliding member 20 slides in the cavity formed by the limiting bump 12, thereby realizing the stability of the omnidirectional sliding of the sliding member 20.

As another embodiment for solving the problem of the sliding member 20 collapsing from the upper portion of the limit projection 12, the forming die of the flower cutter includes a core die cover 80 in combination with fig. 8, 12 and 13, the core die cover 80 being for covering the flower cutter core die 30, and the insert portion 21 of the sliding member 20 being always covered by the core die cover 80.

After the seamless steel pipe is sleeved on the flower-cutter core mould 30, the core mould pressing cover 80 is covered, the core mould pressing cover 80 can limit the sliding piece 20, and the sliding piece 20 is prevented from being broken out from the upper part of the limiting convex block 12 in the sliding process; the stability of the seamless steel tube in the process of being processed is ensured.

As a further embodiment, the mandrel gland 80 ensures the stability of the seamless steel pipe in the process of being processed, but because the mandrel gland 80 covers the broach mandrel 30, after the broach processing is completed, the mandrel gland 80 needs to be removed to remove the processed broach, thereby greatly reducing the processing efficiency. In order to solve the technical problem, the mandrel gland 80 is provided with a gland cavity 81, the gland cavity 81 is arranged in the center of the mandrel gland 80, and the diameter of the gland cavity 81 is larger than the maximum outer diameter of the flower-knife mandrel 30, so that after the flower-knife machining is finished, the machined flower-knife can be directly taken down through the movable flower-knife mandrel 30 without taking down the mandrel gland 80, and then the flower-knife is taken out. Meanwhile, when the flower cutters with different sizes are required to be processed, different flower cutter core dies 30 are required to be adopted, the flower cutter core dies 30 can be directly replaced, and additional operation on the core die pressing cover 80 is not required.

As a further embodiment, in connection with fig. 11 and 12, a groove is formed in the upper portion of the limit bump 12, and a downward protrusion is provided on the distal end of the core mold cover 80 away from the flower-cutter core mold 30, and the protrusion of the core mold cover 80 is engaged with the groove of the limit bump 12. After the core mold pressing cover 80 is covered, the protrusion of the core mold pressing cover 80 is mutually matched with the groove of the limit bump 12, so that the core mold pressing cover 80 cannot move back and forth and left and back on a plane.

As a further embodiment, in connection with fig. 10, the upper portion of the insert portion 21 of the slider 20 is higher than the rest of the slider 20, the insert portion 21 forms a protrusion with respect to the rest of the slider 20, and the protrusion formed by the insert portion 21 is restricted by the protrusion of the core mold gland 80. Specifically, when the slider 20 is away from the flower-cutter core die 30 by a certain distance, the protrusions formed by the embedded portions 21 are mutually abutted by the protrusions of the core die pressing cover 80, so that the slider 20 cannot continue to be away from the flower-cutter core die 30 along the slide way, thereby avoiding the detachment of the slider 20 from the slide way 11.

As a further embodiment, when the second body 40 presses down the slider 20 so that the insert portion 21 of the slider 20 is completely inserted into the insert groove of the corresponding flower cutter core die 30, at this time, the second inner wall 41 of the second body 40 is completely fitted to the slide side wall 22 of the slider 20 and the stopper side wall 120 of the stopper projection 12, and at the same time, the upper surface of the core die pressing cover 80 is fitted to the upper side wall of the inner surface of the second body 40. At this time, the pressures of the second body 40 to the sliding member 20, the limiting bump 12 and the mandrel gland 80 are uniformly distributed, and meanwhile, because the gaps between the mandrel gland 80, the sliding member 20, the limiting bump 12 and the second body 40 are almost absent, the mandrel gland 80, the sliding member 20 and the limiting bump 12 are reversely supported by the second body 40, the damage of the second body 40 caused by the extrusion of extrusion equipment such as a punch is avoided, so that the service life of each part of the forming die of the flower knife is prolonged.
