If the rear left side portion 124 and the rear right side portion 125 and the leg wing portion 17 can be fastened to each other, the leg wing fastening portion is at least one back surface of the drape main body 11 and the leg wing portion 17 ( In other words, it may be arranged on the unclean side.

  As shown in FIGS. 13 to 15, the leg wing part 17 includes a crotch opening 73, a crotch weakening line 74, and a seal 75. The crotch opening 73 is a substantially circular through hole, and the center of the crotch opening 73 is located on the folding line 173. The crotch opening 73 is covered with a substantially rectangular seal 75. In a state before the crotch portion opening 73 is used, the seal 75 is detachably attached on the surface 171 which is a clean surface of the leg wing portion 17. The seal 75 prevents the clean area and the unclean area from communicating via the crotch opening 73.

  The crotch weakening line 74 extends from the lower edge 179 of the leg wings 17 to the lower end of the crotch opening 73. More specifically, the crotch weakening line 74 reaches the lower end of the crotch opening 73 from the other end point opposite to the upper end point 178 of the folding line 173. The edge 179 of the leg wing part 17 is the other edge in the width direction of the leg wing part 17 when the above-described edge 177 is one edge. The crotch weakening line 74 is formed by covering the slit from the lower edge 179 of the leg wing 17 to the lower end of the crotch opening 73 from the back surface 172 side with a strip-shaped linear cut film 76 extending in the vertical direction. . Since the linear cut film 76 is not provided with a hole penetrating from one main surface to the other main surface in the same manner as the linear cut film 122 described above, The front surface 171 and the back surface 172 are discontinuous. In other words, the clean area and the unclean area are not communicated via the crotch weakening line 74.

  The crotch opening 73 is used, for example, when it is necessary to access the intestines in the abdominal cavity from the anus at the end of laparoscopic surgery. When the crotch opening 73 is used, the seal 75 is peeled away from the surface 171 of the leg wing 17 and the patient's anus is exposed. An adhesive layer (not shown) is provided around the crotch opening 73 on the back surface 172 of the leg wing part 17, and the site near the crotch opening 73 of the leg wing part 17 is formed by the adhesive layer. Affixed around

Is done. Accordingly, it is possible to distinguish and hold a surgical instrument code having a relatively high frequency of position change during surgery and a code of a surgical instrument having a relatively low frequency of position change. As a result, the position of the cord can be easily and quickly changed during the operation. Moreover, since the difference in appearance between the first code holder 3 and the second code holder 4 is the difference in color, the first code holder 3 and the second code holder 4 can be easily distinguished. As a result, when the code position is changed, it is possible to prevent the holding of other codes that do not need to be changed from being released.

  As described above, the plurality of first code holders 3 are arranged around the opening 110, and the plurality of second code holders 4 are arranged farther from the opening 110 than the plurality of first code holders 3. Thereby, when changing the position of the code held in the first code holder 3, the code is removed from the first code holder 3, the code is moved, and the code is attached to the first code holder 3. Can be prevented from being inhibited by the cord held in the second cord holder 4. As a result, it is possible to change the position of the cord during the operation more easily and more quickly.

  Each first cord holder 3 includes a tape-shaped first holder main body 31 with a fixed end 34 fixed to the drape main body 11, and a first holder fastening portion disposed at a free end 35 of the first holder main body 31. 32. Thereby, holding | maintenance and release | release (namely cancellation | release of holding | maintenance) of the code | cord | chord by the 1st cord holder 3 can be performed easily. Similarly to the first code holder 3, the second code holder 4 includes a tape-like second holder body 41 and a second holder fastening portion 42 disposed at the free end 45. The cord can be easily held and released by the cord holder 4.

  The first holder main body 31 of the first cord holder 3 is folded in two at a fold line 36, and the first holder fastening portion 32 disposed at the free end 35 of the first holder main body 31 is a fixed end portion. The free end portion 35 is fixed to the fixed end portion 32 by being fixed to the first holder fixing portion 32 arranged at 34. For this reason, it is not necessary to provide a structure (for example, a hook-and-loop fastener) for fixing the free end portion 35 of the first cord holder 3 on the clean surface 111 of the drape main body 11, thereby simplifying the manufacture of the drape 1. be able to. Further, in the first cord holder 3 that is not used for holding the cord, the two first holder fastening portions 32 are fastened to each other so that the first holder fastening portion 32 can be moved to another part of the drape 1. For example, it is possible to prevent the terminal from being unintentionally attached.

  Similarly, in the second cord holder 4, the second holder main body 41 is folded in half, and the second holder fastening portion 42 disposed at the free end 45 of the second holder main body 41 is fixed to the fixed end 44. It is fixed to the second holder fixing portion 42 arranged at the position. Thereby, manufacture of drape 1 can be simplified more. Further, in the second cord holder 4 that is not used, the second holder fixing portion 42 is intentionally attached to another part of the drape 1 by fixing the two second holder fixing portions 42 to each other. On the other hand, it can be prevented from being fixed.

  In the drape 1, the fold 36 of each first cord holder 3 is positioned closer to the opening 110 than the fixed end portion 34 of the first cord holder 3. Thereby, even if the site | part hold | maintained at the 1st cord holder 3 of a code | cord | chord is a case where it pulls toward the opening 110, the fastening of the 1st holder fastening part 32 is not cancelled | released easily. , Can hold the code strongly. As a result, it is possible to suppress the cord from coming off the first cord holder 3 and overlapping the opening 110. In addition, the fixed end 44 of each second cord holder 4 is located closer to the opening 110 than the fold 46. Thereby, when the cord is held in a suspended state by the second cord holder 4, the portion of the cord held by the second cord holder 4 is moved to the two second holder fastening portions 42 by gravity. It will not be pressed. As a result, the holding of the cord by the second cord holder 4 can be prevented from being released unintentionally due to the weight of the cord.

  In the first cord holder 3, the low friction portion 33 is disposed at the center in the longitudinal direction of the first holder body 31. Thereby, since the friction between the first cord holder 3 and the cord is reduced, the cord held by the first cord holder 3 can be easily advanced and retracted in the longitudinal direction. Note that the low friction portion 33 may be omitted when the friction between the first holder body 31 and the cord is so low that the cord can be easily advanced and retracted.

  In the drape 1, the cord is held between the first sheet portion 21 and the second sheet upper portion 227 between the connection edge portion 231 of the pouch 2 and the pouch fastening portion 250. Thereby, also in the position where the pouch 2 is provided, holding | maintenance and release | release of a code | cord | chord can be implement | achieved easily. In addition, by holding a code with a relatively high frequency of position change by the pouch 2, it is possible to quickly cope with the position change of the surgical instrument.

  As described above, the second cord holder 4 is disposed between the pouch 2 and the drape main body 11. As a result, even at the position where the pouch 2 is provided, it is possible to distinguish and hold a code having a relatively high frequency of position change and a code having a relatively low frequency. Further, the cord is held by the pouch 2 at a position closer to the opening 110 than the second cord holder 4, so that the removal of the cord from the pouch 2 and the movement of the cord are held by the second cord holder 4. It is possible to suppress inhibition by the existing code. As a result, it is possible to change the position of the cord during the operation more easily and more quickly.

  In the drape 1, two or more second cord holders 4 may be disposed between the first sheet portion 21 of each pouch 2 and the drape main body 11. In other words, at least one second cord holder 4 is disposed between the pouch 2 and the drape main body 11. As a result, even at the position where the pouch 2 is provided, it is possible to distinguish and hold a code having a relatively high frequency of position change and a code having a relatively low frequency.

  As described above, in the pouch 2, the upper end portion of the first sheet portion 21 is fixed to the drape main body 11, and the lower edge 221 and the lower side edge portions 226 of the second sheet portion 22 are connected to or continuous with the first sheet portion 21. Thus, a connection edge 231 is formed. In addition, since both side edge upper portions 225 of the second sheet portion 22 are not connected to both side edge upper portions 215 of the first sheet portion 21, the second sheet upper portion 227 can be largely separated from the first sheet portion 21. A pouch fastening part 250 is provided at the upper end part 222 of the second sheet part 22. By adopting such a structure for the pouch 2, the pouch 2 can be used for various purposes such as receiving liquid from the opening 110, accommodating a surgical instrument, and holding a cord of the surgical instrument. .

Is fixed to the upper end portion 212 of the first sheet portion 21. For this reason, it is not necessary to provide a structure (for example, a hook-and-loop fastener) for fixing the pouch fixing part 250 of the pouch 2 on the clean surface 111 of the drape main body 11, and the manufacture of the drape 1 can be simplified. it can.

  In the pouch 2, the fastened portion 255 includes two first fastened portions 253 extending in the width direction at both widthwise ends of the first sheet portion 21, and the pouch fastened portion 250 is the second sheet. 2 includes two first pouch fastening portions 251 disposed at both ends in the width direction of the portion 22, and the length in the width direction of each first pouch fastening portion 251 is the width of each first secured portion 253. Shorter than the length of the direction. Thereby, the fastening position of the 1st pouch fastening part 251 can be changed easily in the width direction. As a result, the shape of the second upper opening 233 of the pouch 2 can be easily changed. Further, since the length in the width direction of the first secured portion 253 is longer than the length in the width direction of the first pouch secured portion 251, the first secured pouch portion 251 is connected to the first secured portion 253. It is possible to prevent (or suppress) the first secured portion 253 from being pulled from the first sheet portion 21 by being pulled by the first pouch secured portion 251 when being peeled off.

  In the drape 1, the pouch fastening part 250 includes the second pouch fastening part 252 disposed at the center in the width direction of the second sheet part 22, so that the second upper opening 233 of the pouch 2 is divided into two. Can be divided. Thereby, a several surgical instrument etc. can be accommodated in the pouch 2 so that it may not mutually contact. In addition, the size of the second upper opening 233 can be easily changed according to various types of surgical instruments and the like. In addition, the to-be-fixed part 255 may be provided in strip | belt shape over substantially the full width of the upper end part 212 of the 1st sheet | seat part 21. FIG. In this case, both end portions in the width direction of the to-be-attached portion 255 correspond to the two first to-be-attached portions 253, and the center portion in the width direction corresponds to the second to-be-attached portion 254.

  As described above, the shape retaining member 241 is provided on the upper end portion 222 of the second sheet portion 22. Thereby, the shape of the second upper opening 233 of the pouch 2 can be easily changed or maintained. The shape retaining member 241 does not necessarily have to be provided over substantially the entire length of the second sheet portion 22 in the width direction. In addition, the shape-retaining member 241 may be a plurality of shape-retaining members each having a strip shape extending in the width direction and arranged in the width direction.

  In the drape 1, the two pouches 2 are disposed on the left and right sides of the opening 110. Thereby, it is possible to use the pouch 2 for the various applications described above, whether the surgery is performed from the left side of the patient or the surgery is performed from the right side.

  As described above, the flap 132 is provided in the vicinity of the opening 110 of the drape 1, and the instrument storage bag 5 is attached to the drape 1 by sandwiching the upper end portion of the instrument storage bag 5 with the forceps 50 together with the flap 132. Since the flap 132 can be separated from the base cloth 12, it is possible to prevent a through hole from being formed in the base cloth 12 by the forceps 50 when the instrument housing bag 5 is attached. In addition, when the position of the forceps 50 is changed in order to change the orientation or the like of the instrument housing bag 5, the formation of a through hole in the base cloth 12 is prevented. Various surgical supplies other than the instrument storage bag 5 may be detachably attached to the flap 132 by various means. Also in this case, since the flap 132 can be separated from the base fabric 12, the surgical supplies can be easily attached to the drape 1 without affecting the base fabric 12.

  The flap 132 is a part of the absorbent sheet 13 that is fixed around the opening 110 on the clean surface of the base fabric 12. Thereby, the flap 132 can be easily connected in the vicinity of the opening 110, and the manufacture of the drape 1 can be simplified. Further, the flap 132 is disposed adjacent to the pouch 2. Thereby, when the instrument storage bag 5 is attached to the flap 132, the surgical instrument can be stored by selecting an appropriate one from the instrument storage bag 5 and the pouch 2 according to the type of the surgical instrument.

  In the drape 1, two flaps 132 are disposed on both the left and right sides of the opening 110. As a result, the flap 132 can be used for attachment of surgical supplies, regardless of whether the surgery is performed from the left side or the right side of the patient. Further, by arranging the two flaps 132 adjacent to the two pouches 2, the instrument storage bag 5 and the pouch 2 can be selectively used for storing surgical instruments on the left and right sides of the patient.

  As described above, the drape main body 11 is provided with the front slit 116 extending in the left-right direction from the side edge 117, and the front side wing portion 14 that is folded in two is formed along the front slit 116 on both sides of the front slit 116. Are joined. When the front slit 116 is widened, a portion of the drape main body 11 that is in front of the front slit 116 hangs down on the side of the patient's head, and the front side wing portion 14 spreads out in front of the patient's arm. It hangs down. Thereby, a clean area | region can be ensured also to the side of a patient's head. Therefore, the drape 1 is particularly suitable for laparoscopic surgery in which a practitioner who handles a surgical instrument such as a celiac camera may be located on the side of the patient's head during the surgery.

  Since the front slit 116 is formed by tearing the weakening line 115 provided in the drape main body 11, when the front side wing part 14 is not used, an anesthesiologist or the like works on the side of the patient's head. It is possible to secure a large unclean area as a space. Further, when the front wing portion 14 is used, the front slit 116 can be easily formed by tearing the weakening line 115, and a new clean area can be easily formed on the side of the patient's head. . In the drape 1, the clean surface 111 and the unclean surface 112 of the drape body 11 are discontinuous at the weakening line 115. Thereby, when the front side wing | blade part 14 is not used and in the state before use of the front side wing | blade part 14, the communication of the clean area | region and unclean area | region in the weakening line 115 can be prevented.

  As described above, the front side wing portion 14 before use is temporarily fixed to the dirty surface 112 of the drape main body 11 on the front side of the weakening line 115 by the front side wing temporary fixing portion 149. Thereby, it can prevent that the front side wing | blade part 14 before use hangs down from the drape main body 11, and contacts a floor, a practitioner, a patient, etc. unintentionally.

  The drape main body 11 is provided with a rear slit 114 extending in the left-right direction from the side edge 117, and the rear side wing portion 15 folded in half is joined to both sides of the rear slit 114 along the rear slit 114. When the rear slit 114 is widened, the rear part of the drape body 11 rearward from the rear slit 114 hangs down on the side of the chest and abdomen of the patient, and the rear side wing part 15 spreads to the rear of the patient's arm. Hangs down at Thereby, it is suppressed that the drape main body 11 is pulled up behind the patient's arm and on the side of the chest, and a large clean area can be secured on the side of the patient's chest.

  As described above, the unclean surface of the front side wing portion 14 and the unclean surface of the rear side wing portion 15 are fixed below the patient's arm by the side wing fixing portions 146 and 156. Thereby, it can suppress that the site | part which covers the arm of drape 1 shifts | deviates to the front and back of an arm. Moreover, it can suppress that the said site | part shifts | deviates to the shoulder direction along an arm, and the front-end | tip of an arm is exposed from the drape 1. Therefore, the drape 1 is particularly suitable for laparoscopic surgery in which the posture of the patient is changed at a relatively high frequency during the operation. Further, the lateral wing 16 is continuously joined to the side edges of the rear side wing part 15, the arm covering region 113, and the front side wing part 14, whereby the tip of the arm is exposed from the drape 1. Can be further suppressed.

  In the drape 1, the two front side wing portions 14 are arranged on the left and right sides of the opening 110. Thereby, a clean area | region can be ensured on both the right and left sides of a patient's head. In addition, since the two rear wing portions 15 are arranged on both the left and right sides of the opening 110, a large clean area can be secured on both the left and right sides of the patient's chest. Further, on the left and right sides of the opening 110, the unclean surface of the front wing portion 14 and the unclean surface of the rear wing portion 15 are fixed by the side wing fixing portions 146 and 156, thereby It is possible to suppress the tip of the arm from being exposed from the drape 1.

  As described above, the through hole 71 for inserting the arm of the lever retractor is provided between the two front side wing parts 14 of the drape main body 11. The through hole 71 is penetrated by the seal 72 before the through hole 71 is used. The hole 71 is covered. Thereby, it is possible to prevent the clean area and the dirty area from communicating via the through hole 71. Further, by peeling the seal 72 from the drape main body 11, the arm of the lever retractor can be easily arranged in a state of penetrating the drape 1.

  In the drape 1, the unclean surface of the leg wing portion 17 and the surface of the drape main body 11 facing the leg wing portion 17 are fixed by the leg wing fixing portions 126 and 176 below the patient's leg. Thereby, it can control that the part which covers the leg of drape 1 shifts to the right and left of a leg. Moreover, it can suppress that the said site | part shifts | deviates to the waist part along a leg, and the front-end | tip of a leg is exposed from the drape 1. Therefore, the drape 1 is particularly suitable for laparoscopic surgery in which the posture of the patient is changed at a relatively high frequency during the operation.

  In the leg wings 17, a crotch opening 73 is provided at the center in the longitudinal direction, and the crotch opening 73 is covered with a seal 75 before the crotch opening 73 is used. Thereby, it is possible to prevent the clean area and the unclean area from communicating via the crotch opening 73. Also, by peeling off the seal 75, the patient's anus can be easily accessed.

  The leg wing part 17 is provided with a crotch weakening line 74 extending from the lower edge 179 of the leg wing part 17 (specifically, the lower end point of the folding line 173) to the lower end of the crotch opening 73. The crotch weakening line 74 is torn as necessary when the crotch opening 73 is used, so that a slit 77 is formed. Thus, even when the crotch opening 73 is away from the patient's anus, the patient's anus can be easily accessed through the continuous crotch opening 73 and the slit 77. Moreover, in the crotch weakening line 74, the clean surface and the unclean surface of the leg wings 17 are discontinuous. Thereby, when the crotch part opening 73 is not used and when the crotch part opening 73 is not used, communication between the clean area and the dirty area in the crotch weakening line 74 can be prevented.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

  For example, the first cord holder 3 may be a hook-and-loop mixed tape-shaped surface fastener, like the second cord holder 4. In this case, the base material of the surface fastener is the first holder main body 31, both end portions of the surface fastener are the two first holder fastening portions 32, and the central portion of the surface fastener is the low friction portion 33. In the second cord holder 4, similarly to the first cord holder 3, two surface fasteners that are two second holder fastening portions 42 are joined to both end portions of the second holder main body 41 formed of a nonwoven fabric or the like. Also good.

  The 1st holder fastening part 32 and the 2nd holder fastening part 42 do not necessarily need to be a surface fastener, for example, may be an adhesion layer. The first holder body 31 and the second holder body 41 do not necessarily need to be folded in half, and the shapes of the first holder body 31 and the second holder body 41 may be other than tape.

  The difference in appearance between the first code holder 3 and the second code holder 4 may be other than the color difference between the first holder body 31 and the second holder body 41. For example, the difference in shape and size between the first code holder 3 and the second code holder 4 may be a difference in appearance. Further, the difference in structure between the first code holder 3 and the second code holder 4 may be a difference in appearance. In any case, the first code holder 3 and the second code holder 4 can be easily distinguished from each other because the appearances of the first code holder 3 and the second code holder 4 are different.

  The length of the first pouch fastening portion 251 in the width direction may be approximately the same as the length of the first fastening portion 253 in the width direction. The pouch fixing part 250 and the to-be-fixed part 255 do not necessarily need to be surface fasteners. For example, the pouch fixing part 250 that is an adhesive layer may be directly fixed to the first sheet part 21.

  In the pouch 2, the upper end portion 222 of the second sheet portion 22 extends above the upper end portion 212 of the first sheet portion 21, and the upper end portion 222 of the second sheet portion 22 is connected to the drape main body 11 by the pouch fastening portion 250. It may be fixed so as to be detachable directly. The upper end portion 222 of the second sheet portion 22 only needs to be fixed to the first sheet portion 21 or the drape main body 11 at least at both end portions in the width direction, and is not necessarily limited to the first sheet at the center portion in the width direction. It does not need to be fixed to the part 21 or the drape main body 11.

  The flap 132 does not necessarily need to be a part of the absorbent sheet 13, and a part of the substantially rectangular sheet member is directly fixed to the base fabric 12 with a double-sided tape or an adhesive, and other parts of the sheet member However, it may be used as a flap 132 that can be separated from the base fabric 12. In this case, the sheet member need not necessarily have absorbency. Further, the shape of the flap 132 may be variously changed. In the drape 1, only one flap 132 may be provided on one of the left and right sides of the opening 110.

  The weakening line 115 of the drape main body 11 is not necessarily formed by covering the slit 121 of the base fabric 12 with the linear cut film 122, and may be realized by another structure. For example, the weakening line 115 may be a non-penetrating perforation that does not penetrate the base fabric 12. Alternatively, the weakening line 115 may be a perforation that penetrates the base fabric 12. The crotch weakening line 74 may also have another structure that does not use the linear cut film 76 (for example, a non-perforated perforation).

  The front slit 116 is not necessarily formed by tearing the weakening line 115, and may be formed in the drape main body 11 in advance. In this case, the both sides of the front slit 116 of the drape main body 11 are fastened to each other with a hook-and-loop fastener in the vicinity of the side edge 117, so that the patient's head can be used without using the front side wing portion 14. A large dirty area, which is a work space for anesthesiologists, can be secured on the side of the department.

  The front side wing part 14 and the rear side wing part 15 do not necessarily have to be substantially square sheet members, and may have various shapes (for example, substantially quadrants). Similarly, the leg wings 17 may have various shapes. The side wing fastening portions 146, 156, the front side wing temporary fastening portion 149, and the leg wing fastening portions 126, 176 are not necessarily surface fasteners, and may be adhesive layers, for example.

  In the drape 1, only one pouch 2 may be provided on one of the left and right sides of the opening 110. Further, only one set of the front slit 116 and the front side wing part 14 may be provided on one of the left and right sides of the opening 110 (the same applies to the rear slit 114 and the rear side wing part 15).

  The drape 1 may be used during various operations other than laparoscopic surgery. The drape main body 11 does not necessarily need to cover the whole body of the patient, and may cover a necessary part of the patient's body. In the drape 1, the front side wing part 14, the rear side wing part 15, the side wing part 16, and the leg wing part 17 may be omitted according to the application.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
