Description

Technical Field

[0001] The invention relates to staples and circumcision staplers having them. Background Art

[0002] With the development of medicine and product research and development, more and more minimally invasive medical devices are used in urology and men's clinical surgeries. The circumcision stapler is one of them. The application of the circumcision stapler has many advantages such as less intraoperative bleeding, shorter operation time, minimization of manual operation errors, reduction of postoperative infection, less postoperative pain, and rapid functional recovery. However, the existing circumcision staplers are more complicated to operate. During the operation, the remaining length of the frenulum is judged based on the doctor's experience, which requires a high level of clinical experience from the doctor. Sometimes the operation is not precise enough, which may cause some medical disputes.

[0003] The circumcision stapler is relatively complicated to operate and requires a high level of operation and experience from the doctor. The doctor needs to operate four surgical forceps to control and adjust the length of the frenulum and the inner plate. The remaining length of the frenulum needs to be judged based on the doctor's experience. It requires a high level of clinical experience from the doctor. Sometimes the operation is not precise enough, which will cause the frenulum to be too short.

[0004] In addition, when used, the circumcision stapler is used to achieve the effect of suturing the foreskin, but because the gap between the suture staples is large, there are still more bleeding. Summary of the invention

[0005] The present invention provides a suturing staple, which comprises a base plate, a stitch structure and at least one pair of side wings arranged on the base plate, wherein the stitch structure comprises an inner stitch pair and an outer stitch pair respectively extending axially upward from the base plate, wherein the inner stitch pair and the outer stitch pair both comprise stitches A and stitches B symmetrically arranged in the left-right direction, wherein the stitches A and stitches B of the inner stitch pair and the outer stitch pair are independently configured to be able to be bent toward the inside or the outside; and the pair of side wings comprises two side wings respectively extending laterally toward the outside from the left and right sides of the base plate.

[0006] Preferably, the two flanges extend horizontally or warp upward.

[0009] Preferably, both pin A and pin B of the outer pin pair and the inner pin pair are bent toward the outside.

[0010] Preferably, the two inner pins are bent inwards, and the two outer pins are bent outwards on both sides respectively. The two inner pins are bent inwards to form a closed loop clamping with the bottom plate of the suture nail to form a barrier that mainly prevents bleeding. The two outer pins are bent outwards on both sides to form a semi-closed loop with the side wings on the same side. The adjacent suture nails form a semi-closed loop in the same principle. The two semi-closed loops form a relative closed loop to form a barrier to assist in preventing bleeding.

[0011] Preferably, the four inner and outer pins are bent inwards; the two inner pins are bent inwards to form a closed loop clamping with the bottom plate of the suture nail, forming a first layer of barrier to prevent bleeding; the two outer pins are bent inwards to form a closed loop clamping, forming a second layer of barrier to prevent bleeding.

[0012] Preferably, the four inner and outer stitches are all bent outwards; the two inner stitches and the side wings of the suture nail form a semi-closed loop, and the adjacent suture nails also form a semi-closed loop, and the two semi-closed loops form a relative closed loop, forming the first layer of barrier to prevent bleeding; the two outer stitches are similarly bent outwards to form a relative closed loop clamping, forming a second layer of barrier to prevent bleeding.

[0013] Preferably, the suture staple includes two pairs of side wings, and the two outer pins are bent outward on both sides respectively; the two inner pins are bent inwardly to form a closed loop clamping with the bottom plate of the suture staple, and the foreskin tissue inside will be in a compressed state, forming a barrier that mainly prevents bleeding, and the two outer pins are bent outward on both sides respectively to form a semi-closed loop with the two side wings on the same side, and the adjacent suture staples also form a semi-closed loop, and the two semi-closed loops form a relative closed loop, and the bent back pins and wings form a certain clamping on the foreskin in the middle, forming a barrier to assist in preventing bleeding.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "hold" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the inner sections of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Example 1

[0036] See also Figure 1-2 The present embodiment provides a glans seat of a circumcision stapler, the glans seat comprising a glans cover 1, a connecting rod 2 arranged at the proximal end of the glans cover 1, and a screw rod 3 connected to the connecting rod 2, the screw rod cooperates with the knob to drive the glans seat to move forward and backward, the glans cover 1 defines a glans cavity 100 with an open distal end, the glans cavity is used to accommodate the glans for the circumcision stapler to cut the external foreskin, the inner side wall of the glans cavity 100 is provided with a protrusion 11 extending from the proximal end to the distal end, so that the glans cover provided in the present embodiment increases the overall climbing length of the frenulum compared to the glans cover with a smooth inner wall, so that the frenulum stays more in the glans cover; in addition, the protrusion increases the corresponding distance when the foreskin starts to bypass the outer circle of the glans seat at the center of the glans, ensuring that the foreskin is not too short after circumcision.

[0037] At the same time, in order to prevent the laces from shifting, a limiting portion for positioning the laces is provided on the protrusion. The limiting portion can have various structural forms. In the present embodiment, the limiting portion has the following structural form: a limiting groove 12 for positioning the laces is provided at the center of the protrusion. In this way, the laces are received in the limiting groove 12. This increases the climbing distance of the laces while ensuring that the laces will not deviate arbitrarily during operation, and further ensures that the laces will not be cut too short.

[0038] In this embodiment, the protrusion 11 is a convex strip extending from the proximal end to the distal end of the glans cavity, effectively increasing the climbing distance of the strap, and the convex strip has an arc-shaped surface to avoid damage to the strap.

[0039] Example 2

[0040] See also Figure 1-2 The present embodiment provides a glans seat of a circumcision stapler, the glans seat comprising a glans cover 1, a connecting rod 2 disposed at the proximal end of the glans cover 1, and a screw rod 3 connected to the connecting rod 2, the glans cover 1 defining a glans cavity 100 with a distal end open, the proximal end of the glans cover 1 folded downward to form an annular groove 13;

[0041] A plurality of hooks 5 are provided on the proximal circumference of the glans seat for sutures to be wound around them. In the present embodiment, one end of the suture 6 is passed through the foreskin 7 by a needle and tied to be fixed, and the other end is pulled on the hook 5. In this way, the foreskin can be lifted by passing a plurality of sutures around the foreskin. In this process, the inner plate is moderately tightened by pulling the sutures to ensure that the frenulum is loose to ensure that the frenulum is not cut too much. In this way, the sutures can completely replace the use of hemostatic forceps, and there is no need to clamp the foreskin with a plurality of hemostatic forceps, which is simpler to operate. In addition, since the hemostatic forceps are large in size, it is not conducive to the operation of extending the glans seat into the glans, while the plurality of sutures for lifting the foreskin provided in the present embodiment are small in size and will hardly have any adverse effect on the extension of the glans seat.

[0042] In this embodiment, the outer wall of the glans hood is evenly spaced circumferentially with a plurality of hooks 51, 52, 53, 54, so that the foreskin is lifted circumferentially evenly. To ensure the convenience of operation, the hook has a plurality of hooks 511 from the proximal end to the distal end. The plurality of hooks facilitate the doctor to hang and lock the sutures, so that the doctor can fix the sutures after adjusting the foreskin length for subsequent circumcision operations.

[0043] Specifically, the glans seat further comprises a plurality of sutures, one end of which is arranged on the hook and the other end is used to pass through the foreskin.

[0044] See also Figure 3In the present invention, the doctor passes a suture through the foreskin, fixes one end on the foreskin, and adjusts the length of the foreskin inner plate and the frenulum by pulling the other end. Multiple hook structures can facilitate the doctor to hang and lock the suture, and can achieve adjustment in multiple directions at the same time, so that the foreskin length can be adjusted at any time.

[0045] Example 3

[0046] See also Figure 2 and Figure 4 , this embodiment improves the clock base on the basis of embodiment 1, the proximal end of the glans cavity is folded downward to have an annular groove 13, and the annular groove 13 has a nail plate 131, the nail plate 131 includes a ring-shaped plate body, the plate body is circumferentially spaced with a plurality of inner row nail grooves 1311 and a plurality of outer row nail grooves 1312, the plurality of outer row nail grooves 1312 are arranged on the outside of the plurality of inner row nail grooves 1311, there is a spacing area 1300 between adjacent inner row nail grooves 1311, the outer row nail grooves 1312 can at least cover the spacing area 1300; in this way, the outer row nail grooves just cover the spacing of the inner row nail grooves, forming a 360° closed loop, realizing double-layer protection, and significantly and effectively reducing bleeding during and after surgery.

[0047] Example 4

[0048] The present embodiment provides a suture staple, which includes a base plate 8, and a stitch structure and two side wings arranged on the base plate 8, wherein the stitch structure includes an inner stitch pair and an outer stitch pair respectively extending axially upward from the base plate, wherein the inner stitch pair is located on the inner side of the outer stitch pair, wherein the inner stitch pair includes stitches A 9A and stitches B 9B symmetrically arranged in the left-right direction, wherein the inner stitch pair and the outer stitch pair both include stitches A10A and stitches B10B symmetrically arranged in the left-right direction, wherein the stitches A and B of the inner stitch pair and the outer stitch pair are independently configured to be able to be bent toward the inside or the outside; wherein the two side wings 81, 82 extend laterally toward the outside from the left and right sides of the base plate respectively; thus, the effect of two rows of stitches is obtained without increasing the number of stitches, and a good effect of suppressing bleeding is obtained without increasing the difficulty of operation.

[0049] Exemplary, the present embodiment provides the following suture method:

[0050] Structure 1-staggered warping suture: Figure 6 , Figure 7As shown, the side wings are bent and extended upward. When suturing, the pins of the suture nails are bent along the nail grooves of the glans nail plate, the two inner pins are bent inward, and the two outer pins are bent to the outside on both sides respectively; the two inner pins are bent inward to form a closed loop clamping with the bottom plate of the suture nail, and the foreskin tissue inside will be in a compressed state, which can prevent the tissue here from bleeding outward. This is the main barrier to prevent bleeding. Figure 8 As shown; the two outer stitches are bent outwards on both sides and form a "semi-closed loop" with the side wings on the same side. The suture nails next to it form a "semi-closed loop" in the same principle. The two "semi-closed loops" form a relative closed loop. The bent back stitches and the upwardly bent side wings clamp the foreskin in the middle to a certain extent, which serves as a barrier to assist in preventing bleeding.

[0051] The staple has four pins, two on the inside and two on the outside, and also has two upwardly warped wings in the axial direction, which can increase preloading force.

[0052] Specifically, the pair of wings extend outward from the left and right sides of the bottom plate in the middle position in the front and rear directions. Structure 2-Miss-Seam horizontal stitching:

[0053] like Fig. 9 , Fig.10 It is shown that when sewing, the stitching pins are bent along the nail groove of the hour-end nail board. The two inner stitches are bent inward, and the two outer stitches are bent to the outside of both sides respectively, such as Figure 7 The two inner pins are bent inward to form a closed loop with the bottom plate of the suture nail, and the foreskin tissue inside is in a compressed state to prevent the tissue here from bleeding outward. This is the main barrier to prevent bleeding. Fig.11 As shown; the two outer stitches are bent outwards on both sides to form a "semi-closed loop" with the side wings on the same side, and the suture nails next to it form a "semi-closed loop" in the same principle. The two "semi-closed loops" form a relative closed loop, and the bent back stitches and the horizontal side wings form a certain clamping on the middle foreskin, which is a barrier to assist in preventing bleeding.

[0054] Structure 3 - Side-by-side inward stitching:

[0055] like Fig.12 and Fig.13 As shown, during suturing, the pins of the suture staples are bent along the nail grooves of the nail plate of the clock base, and the four inner and outer pins are bent inward; the two inner pins are bent inward to form a closed loop clamp with the bottom plate of the suture staple, and the foreskin tissue inside will be in a compressed state, which can prevent the tissue here from bleeding outward. This is the first layer of barrier to prevent bleeding; the two outer pins are bent inward to form a closed loop clamp, which is the second layer of barrier to prevent bleeding.

[0056] Structure 4 - Side-by-side outward stitching:

[0057] like Figure 13-14 , when sewing, the stitching pins are bent along the nail groove of the hour-end nail board, and the four stitches on the inside and outside are bent outward; Fig.15 As shown, the two inner pins are bent inwards to form a "semi-closed loop" with the side wings of the suture nail, and the suture nail next to it forms a "semi-closed loop" in the same principle. The two "semi-closed loops" form a relative closed loop, and the bent back pins and the horizontal side wings form a certain clamping on the middle foreskin, which is the first layer of barrier to prevent bleeding; the two outer pins are bent outwards to form a relative closed loop clamping, which is the second layer of barrier to prevent bleeding.

[0058] The suture staples provided by the invention can achieve the effect of two rows of suture staples without increasing the number of suture staples, and can achieve a good effect of inhibiting bleeding without increasing the difficulty of operation.

[0059] Example 5

[0060] See also Fig.17 The present embodiment provides a suture staple, which includes a base plate 8 and a stitch structure arranged on the base plate 8. The stitch structure includes an inner stitch pair and an outer stitch pair extending axially upward from the base plate, respectively. The inner stitch pair is located on the inner side of the outer stitch pair. The inner stitch pair includes stitches A 9A and stitches B 9B symmetrically arranged in the left-right direction. The inner stitch pair and the outer stitch pair both include stitches A 10A and stitches B 10B symmetrically arranged in the left-right direction. The stitches A and stitches B of the inner stitch pair and the outer stitch pair are independently configured to be able to be bent toward the inside or the outside. In this way, the effect of two rows of stitches is obtained without increasing the number of suture staples, and a good effect of suppressing bleeding is obtained without increasing the difficulty of operation.

[0061] Specifically, see Fig.18 The inner pin bent one outward and the other inward to pin A 9A and pin B 9B, adding a row of pins to a traditional row of pins, achieving a significant improvement in the suppression of bleeding.

[0062] Example 6

[0063] See also Fig.19The present embodiment provides a suture staple, which comprises a base plate 8, and a pin structure and two pairs of side wings arranged on the base plate 8, wherein the pin structure comprises an inner pin pair and an outer pin pair respectively extending axially upward from the base plate, wherein the inner pin pair is located on the inner side of the outer pin pair, wherein the inner pin pair comprises pins A 9A and pins B 9B symmetrically arranged in the left-right direction, wherein the inner pin pair and the outer pin pair both comprise pins A 10A and pins B 10B symmetrically arranged in the left-right direction, and the pins A and pins B of the inner pin pair and the outer pin pair are independently configured to be able to be bent toward the inside or the outside;

[0064] The two pairs of side wings include an outer side wing pair and an inner side wing pair. The outer side wing pair is located outside the inner side wing pair. The outer side wing pair includes side wings 810 and 820 extending laterally outward from the left and right sides of the bottom plate respectively; the inner side wing pair includes side wings 811 and 821 extending laterally outward from the left and right sides of the bottom plate respectively. Compared with a single pair of side wings, the two pairs of side wings further enhance the effect of suppressing bleeding.

[0065] For example, see Fig. 20 When suturing, the pins of the suture staples are bent along the nail grooves of the nail plate of the glans base, the two inner pins are bent inward, and the two outer pins are bent to the outside on both sides; the two inner pins are bent inward to form a closed loop clamping with the bottom plate of the suture staples, and the foreskin tissue inside will be in a compressed state, which can prevent the tissue here from bleeding outward. This is the main barrier to prevent bleeding. The two outer pins are bent to the outside on both sides to form a "semi-closed loop" with the two side wings on the same side, and the suture staples next to it form a "semi-closed loop" according to the same principle. The two "semi-closed loops" form a relative closed loop, and the bent back pins and wings form a certain clamping on the foreskin in the middle, which is an auxiliary barrier to prevent bleeding.

[0066] In this way, the effect of the number of staples is obtained on the basis of not increasing the number of staples, and the effect of suppressing bleeding is obtained on the basis of not increasing the operation difficulty.
