DETAILED DESCRIPTION

[0025] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] like Figure 1 , Figure 2 As shown, Figure 1 A structural view of the episiotomy scissors; Figure 2 A structural view of the episiotomy scissors with the identification portion removed.

[0028] The perineal side cutting scissors of the utility model include two scissor arms 1, which are rotatably connected by a rotating shaft. The scissor arm 1 includes a shearing portion and a handle portion 11, and the shearing portion and the handle portion 11 are respectively arranged on both sides of the rotating shaft. The shearing portion includes a connecting section 14 and a shearing section 15. The connecting section 14 extends linearly along the length direction of the handle portion 11, and the shearing section 15 is bent and extended at the end of the connecting section 14 away from the handle portion 11. The shearing section 15 is provided with a shearing blade, and the shearing blades of the two scissor arms 1 are correspondingly arranged to realize the shearing operation by opening and closing.

[0029] The shear sections 15 of the two scissor arms 1 are respectively arranged as an inner shearing portion 12 and an outer shearing portion 13. When performing episiotomy, the inner shearing portion 12 extends into the perineum, and the outer shearing portion 13 is located outside the perineum. A marking portion 2 is detachably provided on the outer shearing portion 13, and the episiotomy length and angle are marked by the marking portion 2.

[0030] Preferably, the width of the shear segment 15 on the inner shear portion 12 gradually decreases in an extension direction away from the corresponding connecting segment 14 to facilitate the inner shear portion 12 to extend into the perineum, and the width of the shear segment 15 on the outer shear portion 13 remains consistent in an extension direction away from the corresponding connecting segment 14, and the width dimension of the shear segment 15 on the outer shear portion 13 is larger than the maximum width dimension of the shear segment 15 on the inner shear portion 12, so that when the inner shear portion 12 and the outer shear portion 13 are closed, the outer shear portion 13 will not be fully covered by the inner shear portion 12, thereby facilitating the disassembly and installation of the identification portion 2.

[0031] Generally, the end of the shearing section 15 where the shearing blade is not provided is provided with a rounded corner to protect the skin outside the perineum and prevent the patient from being injured.

[0032] Preferably, the identification portion 2 includes a connecting seat 21, an identification rod 22 and an identification block 23, the connecting seat 21 includes a first connecting plate 211, a second connecting plate 212 and a third connecting plate 213, the first connecting plate 211 and the second connecting plate 212 are parallel, and the first connecting plate 211 and the second connecting plate 212 are vertically fixed at both ends of the third connecting plate 213 to form a U-shaped connecting seat 21, the shear section 15 on the outer shear portion 13 is arranged between the first connecting plate 211 and the second connecting plate 212, the identification block 23 is arranged on the first connecting plate 211, and the identification rod 22 is arranged on the second connecting plate 212, the first connecting plate 211 corresponds to the outer side surface of the outer shear portion 13 facing away from the inner shear portion 12, the second connecting plate 212 corresponds to the inner side surface of the outer shear portion 13 facing the inner shear portion 12, the identification block 23 is used to identify the side cutting length, and the identification rod 22 is used to identify the side cutting angle.

[0033] Preferably, the projection of the identification rod 22 installed on the outer shearing portion 13 onto the outer side surface of the outer shearing portion 13 is parallel to the cutting edge on the outer shearing portion 13, thereby ensuring that the angle formed by the side cutting direction and the identification rod 22 during side cutting is accurate.

[0034] The end of the identification rod 22 away from the connecting seat 21 is provided with a spherical block 221 to protect the skin outside the perineum and prevent the patient from being injured.

[0035] Specifically, by adjusting the connection seat 21 at different positions on the outer shearing portion 13, the identification block 23 can indicate different areas of the cutting blade on the outer shearing portion 13, so that the length of the episiotomy can be determined by determining the position of the connection seat 21 before episiotomy through the identification block. The identification rod 22 and the second connecting plate 212 are at a certain angle, that is, an angle within the range of 45° to 70° is set between the identification rod 22 and the outer shearing portion 13. Before episiotomy, the identification rod 22 with different angles can be replaced to identify and determine the episiotomy angle, thereby ensuring the accuracy of the episiotomy angle.

[0036] The utility model is provided with the marking part 2 with the marking rod 22 and the marking block 23. By adjusting the marking part 2 and installing it on the outer shearing part 13, the marking block 23 marks the set episiotomy length, and the marking rod 22 marks the set episiotomy angle, thereby ensuring the accuracy of the episiotomy length and the episiotomy angle during episiotomy and avoiding subjective errors.

[0037] Embodiment 2

[0038] like Figure 3 , Figure 4 , Figure 5As shown, Figure 3 is a structural front view of the identification portion; Figure 4 is a structural side view of the identification portion; Figure 5 It is a structural cross-sectional view of the identification portion.

[0039] A plurality of fixing blocks 131 are arranged on the outer side edge of the outer shearing portion 13 facing away from the shearing blade. The fixing blocks 131 are evenly distributed along the extension direction of the shearing section 15 on the outer shearing portion 13. The extension direction of the fixing blocks 131 is perpendicular to the extension direction of the shearing blade on the outer shearing portion 13. Correspondingly, a fixing groove 214 is arranged on the first connecting plate 211, and the fixing block 131 is arranged in the fixing groove 214.

[0040] The fixing grooves 214 are arranged in the fixing blocks 131 at different positions so that different positions of the cutting blade can be marked by the marking block 23 , thereby marking the side cutting length.

[0041] Preferably, each of the fixed blocks 131 is provided with a corresponding scale value to correspond to the indicated length of the identification block 23. When the fixed slot 214 and the corresponding fixed block 131 are fixedly arranged, the length indicated by the identification block 23 is the length marked by the scale value corresponding to the fixed block 131.

[0042] Due to the characteristics of scissors when cutting, the outer side faces the person, so the identification block 23 that can directly mark the length is set on the outer side. The position of the indicated value is set by debugging the position of the identification block 23 in advance, which is more intuitive. At the same time, the scale value is set at the position of the fixed block 131 on the outer side, so that the value to be indicated can be directly and clearly understood during debugging.

[0043] Generally, the scale values ​​marked by each of the fixing blocks 131 range from 5 cm to 6 cm, ensuring that the normal length range of episiotomy is covered.

[0044] Preferably, the identification block 23 extends outward from one side corresponding to the shear blade to form a first indicating sharp corner 231, and the first indicating sharp corner 231 indicates the scale value indicated by the corresponding fixed block 131. Correspondingly, the identification block 23 can also be provided with two second indicating sharp corners 232, and the two second indicating sharp corners 232 are symmetrically arranged on both sides of the first indicating sharp corner 231. The first indicating sharp corner 231 and the second indicating sharp corner 232 have the same extension direction, but the extension length of the second indicating sharp corner 232 is less than the extension length of the first indicating sharp corner 231, which plays an auxiliary indication effect. For example, the distance between the first indicating sharp corner 231 and the second indicating sharp corner 232 is set to 0.5 cm, indicating a certain length range.

[0045] Two stoppers 215 are arranged on the end surface of the first connecting plate 211 close to the outer shearing portion 13, and the fixing groove 214 is formed between the two stoppers 215. The cross-sectional width of the stopper 215 is consistent with the gap between two adjacent fixing blocks 131, so that the stopper 215 can be arranged between two adjacent fixing blocks 131. Generally, the outer shearing portion 13 is inserted between the first connecting plate 211 and the second connecting plate 212, and the corresponding arrangement of the three fixing blocks 131 and the two stoppers 215 can realize the position fixing of the connecting seat 21 on the outer shearing portion 13 under certain circumstances.

[0046] Preferably, a locking hole 216 and a locking block are provided on the first connecting plate 211, and the locking hole 216 is vertically arranged at the bottom of the fixing groove 214, and the diameter of the locking hole 216 is larger than the groove width of the fixing groove 214, and the locking block is threadedly connected in the locking hole 216, and one end of the locking block can be moved into the fixing groove 214, so that it can be in close contact with the corresponding fixing block 131 to realize the fixing operation of the fixing block 131 in the fixing groove 214.

[0047] Specifically, the depth of the locking hole 216 is greater than the difference between the depths of the first connecting plate 211 and the fixing groove 214 , so that the locking block can extend into the fixing groove 214 and fit with the fixing block 131 .

[0048] The locking block includes a locking section 217 and an adjusting section 218. The locking section 217 is threadedly connected to the locking hole 216. The adjusting section 218 is fixed to the end of the locking section 217 and arranged outside the locking hole 216. The operator rotates the adjusting section 218 to achieve the overall twisting of the locking block, thereby achieving the locking or unlocking operation. The adjusting section 218 is generally set to be a cylindrical shape with a cross-sectional diameter larger than the cross-sectional diameter of the locking section 217, and the outer circumferential surface of the adjusting section 218 is provided with anti-slip grooves to facilitate the operator to perform twisting adjustment.

[0049] The first connecting plate 211 is provided with a limiting strip 219 corresponding to the locking block. The limiting strip 219 is provided in a U-shape. Both ends of the limiting strip 219 are fixedly connected to the first connecting plate 211. The adjusting section 218 is provided in the limiting strip 219, so as to limit the travel length of the adjusting section 218 moving along the axis, thereby preventing the locking block from loosening and detaching from the locking hole 216.

[0050] When in use, the identification rod 22 and the external cutting part 13 are both located outside the perineum. Generally, the identification rod 22 is vertically set and positioned with the anus, and combined with the initial position of the incision, the placement of the perineal episiotomy scissors can be quickly and accurately positioned, and the episiotomy angle can be determined; and the indicated position of the identification block 23 on the external cutting part 13 can accurately determine the episiotomy incision length, reduce tissue damage, and use the utility model to achieve objective standard intuitive operation in both episiotomy length and episiotomy angle, eliminating various subjective errors existing in the existing scissors during episiotomy. The operation has high precision, convenient operation, and improved safety of episiotomy.

[0051] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
