Description

  The present invention relates to drapes.

  In performing surgery on a patient, drapes are used that are placed over portions of the patient's body. By using the drape, the operator leaks a body fluid such as blood generated during the operation or a liquid such as saline used for the operation to the operating table or the patient's body or scatters around. Can be prevented. A common drape is provided with a sheet having an opening for exposing a part of a patient's body (for example, see Patent Document 1). When using the drape, the surgeon can access the surgical field through the opening by placing the drape opening in the patient's body.

JP 2007-68573 A

  By using the drape, the operator can prevent the operating table and the patient's body from being contaminated by the liquid generated during the operation as described above. However, depending on the part of the body to be operated, the position of the opening of the drape may be shifted when the drape is attached to the patient or when the drape is used.

  For example, in a catheter procedure by dTRA (distal transradial approach) that punctures a palm artery that runs through a hand and performs treatment through the puncture site, an opening of a drape is formed to perform a treatment on a patient's hand (for example, the back of the hand). Place in hand. However, the size of the hand varies from patient to patient, and the surface of the hand has a complicated shape with irregularities. In addition, when the patient moves his hand, the hand shape is deformed. Therefore, when the operator wears the drape on the patient, it is difficult to spread the drape while preventing the opening of the drape from being displaced from the portion to be treated. Further, while the drape is being used while being spread, the position of the drape is difficult to stabilize, so that the position of the opening may be shifted from the treatment target site together with the drape.

  An object of the present invention is to provide a drape capable of preventing a position of a surgical opening from being shifted from a treatment target site of a patient when the patient is worn or used in view of the above problems.

  A drape according to the present invention is a drape including a surgical opening that exposes a part of a patient's body surface, and is capable of holding a sheet covering a part of the patient's body and a part of the patient's body. A space portion and a bag portion having an insertion port through which a part of the patient's body can be inserted into the space portion, wherein the sheet and the bag portion are fixed at a peripheral portion of the surgical opening. By doing so, they are integrally configured.

  When the surgeon wears the drape on the patient, the operator opens the seat while holding a part of the patient's body by the bag, so that the position of the surgical opening formed in the drape can be changed to the part to be treated by the patient. Deviation can be prevented. The drape is used while a part of the patient's body is held in the bag while the drape is worn on the patient. Since the drape sheet is fixed to the bag portion, the position of the sheet is stabilized. Thereby, the drape can prevent the position of the surgical opening from being shifted from the treatment target site of the patient during the operation.

FIG. 5B is a cross-sectional view corresponding to FIG. FIG. 4 is a cross-sectional view of a state in which a hand H is inserted into a 120.

  In a state before the sheet 110 is attached to the hand H (for example, a state before use in which the sheet 110 is transported or stored) or a state where the sheet 110 is attached to the hand H but before an operation is performed, FIG. As shown, it can be folded into a predetermined shape. The procedure for folding the sheet 110 will be described later.

  As shown in FIGS. 1, 2, and 3, the surgical opening 109 can be formed, for example, in a circular shape. When the drape 100 is used for a dTRA procedure, the surgical opening 109 can be arranged at any position where at least a part of the back Hb of the hand H of the patient P can be exposed in the drape 100.

When the sheet 110 is formed so as to have a rectangular shape when the sheet 110 is expanded, for example, one side of the expanded state has 1000 mm to 3000 mm, and the area of the expanded state is 3 × it can be formed to have a ^{10 6 mm 2 ~6 × 10 6} mm 2. When the surgical opening 109 has a circular shape and the application of the drape 100 is a dTRA procedure, the surgical opening 109 may be formed to have a diameter of, for example, 20 mm to 50 mm. Can be.

  As shown in FIGS. 5A and 5B, the sheet 110 has a first layer 111 arranged opposite to the bag section 120 and a surface of the first layer 111 arranged opposite to the bag section 120. And a second layer 112 disposed on the opposite side.

  The first layer 111 is formed of a sheet having waterproof and antibacterial properties capable of preventing the liquid absorbed by the sheet 110 from contacting the body surface of the patient P and contaminating the operating table and the body of the patient P. ing. The second layer 112 is formed of a sheet having an absorbability capable of absorbing a body fluid such as blood or a liquid such as physiological saline.

  As shown in FIGS. 5A and 5B, the surface of the first layer 111 on the side facing the bag portion 120 forms the back surface (inner surface) 110 b of the sheet 110. In addition, the surface of the second layer 112 opposite to the surface disposed opposite to the first layer 111 forms the surface (outer surface) 110 a of the sheet 110.

  The first layer 111 is not particularly limited as long as it is formed of a material having a liquid absorbing property. For example, a sheet formed of a woven fabric having liquid absorbency, a nonwoven fabric (including Spunbond Meltblown Spunbond Nonwovens), cotton, pulp, chemical fiber, a superabsorbent polymer (for example, sodium polyacrylate), or the like can be used. Can be used. The second layer 112 is not particularly limited as long as it is formed of a material having waterproofness and antibacterial properties. For example, a laminated sheet or the like subjected to waterproof antibacterial processing can be used.

  As shown in FIGS. 5A and 5B, a fixing portion 130 for fixing the sheet 110 and the bag portion 120 is provided on the back surface 110b of the sheet 110. The fixing part 130 can be formed in a shape surrounding the periphery of the through hole 119 of the sheet 110. In the present embodiment, the fixing portion 130 is formed in a circular shape. The fixing part 130 can be formed of, for example, an adhesive or a fusion part where the sheet 110 and the bag part 120 are fused.

  As shown in FIG. 5A, the sheet 110 has a through-hole 119 penetrating in the thickness direction of the sheet 110 (vertical direction in FIG. 5A). The bag part 120 has a communication hole 129 that communicates the space part 124 of the bag part 120 with the outside of the bag part 120.

  The surgical opening 109 of the drape 100 is formed by a through hole 119 of the sheet 110 and a communication hole 129 of the bag 120. The sheet 110 and the bag part 120 are arranged such that at least a part of the through hole 119 and at least a part of the communication hole 129 overlap.

  As shown in FIGS. 5A and 5B, the fixing portion 130 is provided in a peripheral portion of the surgical opening 109 provided in the drape 100. In the present embodiment, the peripheral portion of the surgical opening 109 in which the fixing portion 130 is provided means a predetermined range including the peripheral portion 119a of the through hole 119 of the sheet 110 and the peripheral portion 129a of the communication hole 129 of the bag portion 120. I do. The specific position and range of the peripheral portion of the surgical opening 109 to which the sheet 110 and the bag 120 are fixed are not particularly limited.

  As shown in FIGS. 2 and 3, the through hole 119 of the sheet 110 and the communication hole 129 of the bag part 120 are formed in a circular shape similarly to the surgical opening 109. However, the shape of the surgical opening 109 and the shape of the through hole 119 of the sheet 110 and the communication hole 129 of the bag portion 120 that form the surgical opening 109 may be a part of the body of the patient P to be treated. There is no particular limitation as long as it can be exposed from the drape 100. For example, each of the surgical opening 109, the through hole 119, and the communication hole 129 has an elliptical shape, a rectangular shape, and the unevenness of the back Hb of the hand H when the bag 120 is attached to the back Hb of the hand H of the patient P. A three-dimensional shape or the like arranged three-dimensionally may be used. Further, the position where the surgical opening 109 is formed, the size of the surgical opening 109, the number of the surgical opening 109, and the like are not particularly limited.

  As shown in FIGS. 5A, 5B, and 6, the sheet 110 has a convex portion 115 disposed on the surface 110a of the sheet 110 so as to surround the surgical opening 109.

  As shown in FIG. 6, the protrusion 115 protrudes toward the direction away from the surface 110 a of the sheet 110 (the side opposite to the side on which the bag 120 is disposed, and the upper side in FIGS. 5A and 5B). I have.

  As shown in FIGS. 5A and 5B, the convex portion 115 has a main body 115a disposed on the surface 110a of the sheet 110, and a hole 115b disposed so as to overlap the surgical opening 109. I have.

  In the present embodiment, the convex portion 115 is formed in a circular shape. The inner peripheral edge and the outer peripheral edge of the upper surface of the convex portion 115 are chamfered so as to have a curved cross-sectional shape. Since the hole 115b of the convex portion 115 is arranged so as to overlap with the surgical opening 109, the body surface of the back Hb of the hand H is in a state in which the drape 100 is mounted on the patient P, And is exposed to the outside through the hole 115b.

  As shown in FIG. 6, when forming an access path from the body surface side of the back Hb of the hand H to the inside of the palm artery, the operator places the needle 210 of the puncture device 200 such as an indwelling needle on the back Hb of the hand H. Puncture the surface of the living body. When puncturing the needle part 210 into the living body surface, the surgeon makes the needle part 210 abut on the main body part 115a of the convex part 115 arranged on the surface 110a of the sheet 110. By moving the needle 210 of the puncture device 200 along the main body 115a of the projection 115, the surgeon can move the needle 210 while guiding the needle 210 with the main body 115a of the projection 115. By moving the needle part 210 along the main body part 115a of the convex part 115, the surgeon can prevent the needle part 210 from being displaced at the insertion position into the living body surface. In addition, the surgeon can perform puncturing while maintaining the puncturing angle of the needle unit 210 constant.

  The convex portion 115 is flexible so that when the needle portion 210 of the puncture device 200 is moved along the main body portion 115a of the convex portion 115, the needle portion 210 can be appropriately held by the main body portion 115a of the convex portion 115. It is preferable to have the property. When the convex portion 115 is formed to have flexibility as described above, the convex portion 115 can be formed of, for example, a polyurethane resin, a silicone resin, an isobutylene resin, a hydrogel, or the like.

  Regarding the shape and position of the convex portion 115, at least a part of the convex portion 115 is arranged around the surgical opening 109, and the medical instrument such as the puncture device 200 is inserted into the back Hb of the hand H exposed from the surgical opening 109. There is no particular limitation as long as the main body 115a of the protrusion 115 can be used as a guide for guiding the instrument. For example, the protrusion 115 may not be arranged so as to surround the entire periphery of the surgical opening 109.

  For example, the protrusion 115 may be formed integrally with the sheet 110 so as not to be separated from the sheet 110, or may be formed separately from the sheet 110 so as to be separated from the sheet 110. Good. When the convex portion 115 is configured to be separable from the sheet 110, a member having an adhesive property such as an adhesive portion 140 to be described later is provided on a surface of the convex portion 115 that is disposed to face the surface 110a of the sheet 110. Can be.

  In the case where the convex portion 115 is arranged so as to surround the periphery of the surgical opening 109 as shown in the present embodiment, when performing a treatment such as puncture of the back Hb of the hand H of the patient P, the surgeon may use the convex portion. A saline solution or an echo gel can be filled in the hole 115b of the portion 115. By filling the saline 115 or the echo gel into the hole 115b of the convex portion 115, the surgeon can easily perform a blood vessel check operation using an ultrasonic image at the time of puncturing. In addition, in the drape 100 according to the present embodiment, as shown in FIG. 5B, an adhesive portion 140 is arranged on the bag portion 120. Therefore, the bag part 120 and the back Hb of the hand H of the patient P are fixed by the adhesive part 140 so that no gap is formed between them. Therefore, when the saline 115 or the echo gel is filled in the hole 115b of the convex portion 115 with the drape 100 attached to the patient P, the saline or the echo gel moves into the space 124 of the bag 120. (Leakage) can be suppressed.

<How to fold the seat>
The method of folding the sheet 110 is not particularly limited. For example, a procedure as described below can be adopted.

  FIGS. 4A to 4C show states before and after the sheet 110 is folded. 4A to 4C, the sheet 110 is illustrated in a simplified manner for simplicity of description.

  The sheet 110 may be folded, for example, in a state where the sheet 110 is fixed to the bag section 120, or may be fixed to the bag section 120 in a state where the sheet 110 is folded. Hereinafter, a procedure for folding the sheet 110 in a state where the sheet 110 is fixed to the bag portion 120 will be described.

  As shown in FIG. 4A, for example, predetermined folds 116a and 116b can be formed on the sheet 110 in advance.

  The first fold 116a is a fold that extends substantially linearly in the vertical direction of the sheet 110 (the vertical direction in FIG. 4A). The plurality of first folds 116a are formed at predetermined intervals in the lateral direction of the sheet 110 (the left-right direction in FIG. 4A). The second fold 116b is a fold that extends substantially linearly in the lateral direction of the sheet 110. The plurality of second folds 116b are formed at predetermined intervals in the longitudinal direction of the sheet 110. In the present embodiment, the first fold 116a and the second fold 116b are orthogonal to each other on the plan view shown in FIG.

  As shown in FIGS. 4A and 4B, the worker who folds the sheet 110 moves the sheet 110 from both lateral ends of the sheet 110 toward the center of the sheet 110 along the first fold 116a. The first folded portion 117a is formed by valley-folding 110. The operator folds the sheet 110 so that the through-hole 119 formed substantially at the center position of the sheet 110 does not overlap the first folded portion 117a.

  Next, as shown in FIGS. 4B and 4C, the worker moves the sheet 110 from both ends in the vertical direction to the center side of the sheet 110 along the second fold line 116b. Is folded in a valley to form a second folded portion 117b. The operator folds the sheet 110 so that the through-hole 119 formed substantially at the center position of the sheet 110 does not overlap the second folded portion 117b.

  The operator can fold the sheet 110 by folding the sheet 110 in the above-described procedure so that the through holes 119 do not overlap with the folded portions 117a and 117b of the sheet 110. In using the drape 100, the sheet 110 can be provided in a folded state as shown in FIG.

  The folding and unfolding of the sheet 110 can be performed reversibly. For example, it is also possible to once unfold the folded sheet 110 and then fold it again.

<Bag part>
As shown in FIGS. 2 and 3, the bag unit 120 includes a finger holding unit 126 that can individually hold the fingers f1, f2, f3, f4, and f5 of the hand H of the patient P, and the hand H of the patient P. And a base 127 disposed so as to cover the instep Hb and the palm Hp (see FIG. 5B). In each drawing, reference numeral f1 indicates a thumb, reference numeral f2 indicates an index finger, reference numeral f3 indicates a middle finger, reference numeral f4 indicates a ring finger, and reference numeral f5 indicates a little finger.

  As shown in FIG. 2, the finger holding unit 126 is located closer to the distal end side (upper side in FIG. 2) in the insertion direction of inserting the hand H into the insertion slot 125 than the base 127.

  The finger holding part 126 can hold a first holding part 126a that can hold the thumb f1, a second holding part 126b that can hold the index finger f2, a third holding part 126c that can hold the middle finger f3, and a ring finger f4. A fourth holding portion 126d and a fifth holding portion 126e capable of holding the little finger f5.

  The first holding portion 126a has an internal space (not shown) formed in a size capable of covering the fingertip from the base of the thumb f1 of the hand H. Similarly, each of the other holding portions 126b, 126c, 126d, and 126e has an internal space (shown in the figure) that is large enough to cover the fingertips from the bases of the fingers f2, f3, f4, and f5 of the hand H. (Omitted).

  The base portion 127 of the bag portion 120 is formed in a size that can cover a certain range on the base end side (lower side in FIG. 2) of the hand H than the fingers f1, f2, f3, f4, and f5. It has an internal space (not shown).

  The internal spaces of the holding portions 126a, 126b, 126c, 126d, 126e communicate with the internal space of the base 127. In the present embodiment, a space portion 124 of the bag portion 120 is formed by the internal spaces of the holding portions 126a, 126b, 126c, 126d, 126e and the internal space of the base portion 127.

  Each of the holding units 126a, 126b, 126c, 126d, and 126e holds the respective holding unit 126a in a state where the fingers f1, f2, f3, f4, and f5 are held by the holding units 126a, 126b, 126c, 126d, and 126e, for example. , 126b, 126c, 126d, 126e and the respective fingers f1, f2, f3, f4, f5 come into contact with each other, and the respective holding portions 126a, 126b, 126c, 126d, 126e and the respective fingers f1, f2, f3, It can be formed in a shape and size that can generate a frictional force between f4 and f5. Since the finger holding unit 126 can generate the frictional force as described above, the position of the bag unit 120 is shifted from the hand H of the patient P when the bag unit 120 is mounted on the hand H of the patient P. Effective prevention can be achieved.

  As shown in FIG. 2, each of the holding portions 126a, 126b, 126c, 126d, and 126e is formed in a shape that covers from the base of the finger to the fingertip. However, each of the holding portions 126a, 126b, 126c, 126d, and 126e may not be formed in a shape that covers from the base of the finger to the fingertip. Each of the holding portions 126a, 126b, 126c, 126d, 126e may have, for example, a shape (a shape exposing a fingertip) that covers only a certain range on the base side of the finger. In addition, the shape of each of the holding portions 126a, 126b, 126c, 126d, and 126e may be different.

  The base 127 may have a shape extending toward the forearm A, for example, so as to hold a part of the wrist or the forearm A together with the back Hb of the hand H and the palm Hp of the hand H. Further, the base 127 can be formed in a shape and a size capable of generating a frictional force between the base 127 and the hand H, for example, like the finger holding unit 126.

  As shown in FIG. 2, the bag portion 120 has a contact portion 128 for bringing the peripheral portion 125 a of the insertion port 125 into close contact with a part of the patient P's body.

  In the present embodiment, the contact portion 128 is provided so that the peripheral portion 125a of the insertion port 125 is brought into close contact with the vicinity of the wrist of the patient P. The peripheral portion 125a of the insertion slot 125 is a portion including a predetermined range on the tip side (upper side in FIG. 2) of the bag portion 120 with respect to the insertion slot 125. The specific position and range of the peripheral portion 125a of the insertion slot 125 are not particularly limited.

  The contact portion 128 can be formed of, for example, a rubber band attached to the base 127 of the bag portion 120. The contact portion 128 is arranged along the circumferential direction of the insertion port 125.

  The contact portion 128 can be formed to have a diameter equal to or smaller than the hand H or wrist of the patient P. When the patient P inserts the hand H into the bag portion 120 by the close contact portion 128 having a diameter equal to or smaller than the hand H or the wrist of the patient P as described above, The peripheral portion 125a of the insertion port 125 can be tightened and closely attached to the vicinity of the wrist of the patient P.

  Note that the contact portion 128 can also be configured with a string or the like capable of fastening the peripheral portion 125a of the insertion port 125 to the patient P. Further, the rubber band or the string forming the close contact portion 128 may be integrally attached to the bag portion 120 or may be formed as a separate member from the bag portion 120.

  As shown in FIGS. 5A and 5B, the bag section 120 includes a first layer 121 arranged to face the body surface of the patient P, and a side arranged to face the body surface of the first layer 121. And a second layer 122 disposed on a surface opposite to the surface.

  A part of the surface 120 a of the second layer 122 of the bag section 120 facing the sheet 110 is fixed to the sheet 110 via the fixing section 130. Further, an adhesive portion 140 and a peeling member 150 are arranged on a surface 120b of the first layer 121 of the bag portion 120 facing the living body surface.

  The communication hole 129 formed in the bag portion 120 penetrates a portion of the bag portion 120 arranged on the sheet 110 side in the thickness direction (the vertical direction in FIGS. 5A and 5B). The communication hole 129 of the bag part 120 is formed in the same circular shape as the through hole 119 of the sheet 110. Further, in the present embodiment, the communication hole 129 and the through hole 119 are arranged such that the whole thereof overlaps in plan view.

  The relative positional relationship between the surgical opening 109 and the insertion port 125 in the drape 100 is not particularly limited. However, the entirety of the surgical opening 109 is disposed on the distal end side (obliquely upper left side in the plan view shown in FIG. 2) of the insertion direction for inserting the hand H into the insertion opening 125 rather than the insertion opening 125 of the bag portion 120. Is preferred. When the surgical opening 109 and the insertion port 125 are arranged so as to overlap on the plan view shown in FIG. When the liquid leaks into the space portion 124 of the bag portion 120 through the surgical opening 109, the liquid easily leaks from the space portion 124 of the bag portion 120 to the outside through the insertion port 125. Therefore, the insertion port 125 is disposed at a position away from the position where the surgical opening 109 is formed by a predetermined distance from the position opposite to the insertion direction of the hand H (the lower right side in the plan view shown in FIG. 2). Is preferred.

  As shown in FIGS. 5A and 5B, an adhesive portion 140 for attaching the peripheral portion of the surgical opening 109 of the sheet 110 to the body surface of the patient P is arranged on the bag portion 120.

  The adhesive section 140 can be shaped to conform to the shape of the surgical opening 109. In this embodiment, since the surgical opening 109 is formed in a circular shape, the adhesive portion 140 is also formed in a circular shape.

  As shown in FIG. 5A, the drape 100 has a peeling member 150 attached to the adhesive section 140.

  The peeling member 150 is arranged so as to cover the adhesive section 140 before the drape 100 is used. The peeling member 150 prevents the adhesive portion 140 from adhering to the bag portion 120 or the body surface of the patient P.

  The shape of the peeling member 150 in plan view is substantially the same as that of the adhesive portion 140 so that the adhesive portion 140 can be covered. In the present embodiment, since the adhesive portion 140 is formed in a circular shape, the peeling member 150 is also formed in a circular shape.

  When fixing the sheet 110 to the hand H of the patient P, the surgeon inserts his / her finger into the space 124 of the bag 120 via the surgical opening 109 and removes the peeling member 150 from the adhesive 140. The operator fixes the sheet 110 to the hand H of the patient P via the adhesive portion 140 by removing the peeling member 150 from the adhesive portion 140 and then bringing the adhesive portion 140 into contact with the upper Hb of the hand H of the patient P. can do.

  The first layer 121 of the bag section 120 can be made of, for example, the same material as that exemplified as the constituent material of the second layer 112 of the sheet 110 described above. In addition, the second layer 122 of the bag portion 120 can be made of, for example, the same material as that exemplified as the constituent material of the first layer 111 of the sheet 110 described above.

  Note that at least one of the first layer 121 and the second layer 122 of the bag unit 120 can be made of, for example, silicone rubber, latex rubber, other resin material, or the like. When each of the layers 121 and 122 of the bag unit 120 is made of the above-described material, the finger holding unit 126 and the base 127 have elasticity. Therefore, when the bag portion 120 is attached to the hand H, the bag portion 120 comes into close contact with the hand H, and the position of the bag portion 120 can be effectively prevented from being shifted during the operation. When the above-described material is used to provide the bag portion 120 with elasticity, the bag portion 120 may be formed at any position (for example, at any position on the surface of the hand H facing the back Hb shown in FIG. 5B). Alternatively, an absorbing member capable of absorbing a liquid such as a bodily fluid or a physiological saline can be disposed on an arbitrary portion of the surface of the hand H facing the palm Hp). When the absorbing member is provided, the absorbing member may be provided instead of the adhesive portion 140.

  The adhesive portion 140 can be formed of, for example, a silicone adhesive, an acrylic adhesive, a natural rubber adhesive, a vinyl adhesive, or the like. The adhesive force (adhesive force) of the adhesive portion 140 is not particularly limited, but is, for example, 0.3 to 0.4 N / 10 mm.

  The release member 150 can be formed of, for example, paper, a plastic sheet, a laminate film, a woven fabric, a nonwoven fabric, or the like. The surface of the peeling member 150 that faces the adhesive section 140 may be coated with silicone or may be coated with a fluorine-based release agent.

<How to use drape>
Next, a procedure for using the drape 100 will be described. Hereinafter, a procedure when the drape 100 is used for a dTRA procedure will be described.

  The operator prepares the drape 100 in a state where the sheet 110 is folded. As shown in FIG. 2, the surgeon inserts the hand H of the patient P into the space 124 of the bag 120. The fingers f1, f2, f3, f4, f5 of the hand H of the patient P are inserted into the holding parts 126a, 126b, 126c, 126d, 126e. The surgeon places the back Hb and the palm Hp of the hand H of the patient P in the base 127 of the bag unit 120.

  At the stage of attaching the drape 100 to the patient P, the sheet 110 is folded so that the surgical opening 109 faces the outside of the sheet 110 as shown in FIG. 2 (see FIG. 4C). Therefore, when the surgeon mounts the bag portion 120 on the patient P, the operator can easily arrange the surgical opening 109 at a desired site of the back Hb of the hand H of the patient P.

  When the surgeon wears the bag portion 120 on the patient P, a part of the back Hb of the hand H of the patient P is exposed to the outside through the surgical opening 109 as shown in FIG. Further, when the bag portion 120 is attached to the patient P, the contact portion 128 provided on the bag portion 120 causes the peripheral portion 125a of the insertion port 125 to be in close contact with the vicinity of the wrist of the patient P. The fingers f1, f2, f3, f4, and f5 of the patient P are individually held by the holding units 126a, 126b, 126c, 126d, and 126e.

  Next, the surgeon removes the peeling member 150 that covers the adhesive portion 140 arranged on the bag portion 120 via the surgical opening 109 of the drape 100. As shown in FIG. 5B, the surgeon fixes the bag unit 120 to the hand H of the patient P by bringing the adhesive unit 140 into contact with the back Hb of the hand H of the patient.

  Next, the surgeon adjusts the posture of the patient P so that the forearm A and the hand (right hand) H of the patient P are arranged on the chest and abdomen of the patient P as shown in FIG.

  Next, as shown in FIGS. 1 and 3, the surgeon spreads the sheet 110 fixed to the bag section 120. The surgeon arranges the drape 100 such that a part of the body of the patient P (arbitrary part such as the lower limb, abdomen, and chest) is covered with the sheet 110.

  When the operator spreads the sheet 110, the hand H of the patient P is held in the space 124 of the bag part 120, so that the positions of the sheet 110 and the bag part 120 can be prevented from shifting. Thereby, it is possible to prevent the surgical opening 109 of the drape 100 from being displaced from the site of the back Hb of the hand H to be treated.

  The operator can mount the drape 100 on the patient P by performing the above procedure.

  The drape 100 stably holds the hand H of the patient P in the space 124 of the bag 120 even while the operation on the patient P is being performed. Therefore, even when the patient P moves to spread or grasp the hand H during the operation, it is possible to prevent the positions of the seat 110 and the bag portion 120 from shifting. Therefore, since the patient P can move the hand H during the operation, fatigue caused by maintaining the hand H in a constant posture during the operation can be minimized. Thereby, the patient P can reduce stress during the operation.

  In particular, since the drape 100 according to the present embodiment includes the finger holding unit 126 that can individually hold the fingers f1, f2, f3, f4, and f5 of the hand H, the patient P performs surgery. During this period, the fingers f1, f2, f3, f4, f5 can be moved freely. Therefore, the drape 100 can further reduce the stress during the operation of the patient P. In addition, the finger holding unit 126 individually holds the fingers f1, f2, f3, f4, and f5, so that it is compared with a case where all the fingers f1, f2, f3, f4, and f5 are held in one space. Thus, the inside of the space 124 can be prevented from getting stuffy.

  During the operation on the hand H of the patient P, the body fluid may flow out of the patient P, or the operator may use a physiological saline. At this time, if there is a gap between the communication hole 129 of the bag part 120 and the back Hb of the hand H of the patient P, various liquids generated during the operation will be supplied to the space of the bag part 120 via the surgical opening 109. It may leak to the part 124. In the drape 100, the contact portion 128 causes the peripheral portion 125a of the insertion port 125 to be in close contact with the vicinity of the wrist of the patient P. Therefore, even if various liquids generated during the operation leak into the space 124 of the bag 120, the drape 100 allows the various liquids generated during the operation to flow out of the space 124 through the insertion port 125. Leakage to the outside can be prevented.

  In the present embodiment, the second layer 112 of the sheet 110 and the first layer 121 of the bag section 120 are formed so as to absorb liquid. Therefore, the drape 100 can absorb various liquids generated during the operation in each of the layers 112 and 121, and can prevent the liquid from contaminating the operating table and the body of the patient P. Further, in the drape 100, since the first layer 111 of the sheet 110 and the second layer 122 of the bag portion 120 have antibacterial properties and waterproofness, the liquid absorbed by the sheet 110 and the bag portion 120 contaminates the clean field. Can be prevented. When the second layer 122 of the bag section 120 is formed of a laminate sheet, heat hardly escapes from the space section 124 of the bag section 120, so that the heat retaining property of the bag section 120 can be improved.

  As described above, the drape 100 according to the present embodiment is a drape including the surgical opening 109 that exposes a part of the body surface of the hand H of the patient P, and a sheet 110 that covers a part of the body of the patient P, The seat 110 and the bag 120 have a space 124 that can hold the hand H of the patient P and an insertion port 125 that can insert the hand H of the patient P into the space 124. , And is integrally formed by being fixed at the periphery of the surgical opening 109.

  When the surgeon mounts the drape 100 on the patient P, the surgeon spreads the sheet 110 while holding the hand H of the patient P by the bag portion 120, so that the position of the surgical opening 109 formed in the drape 100 is reduced. It is possible to prevent deviation from the treatment target site of P. The drape 100 is used in a state where the hand H of the patient P is held by the bag 120 while the drape 100 is worn on the patient P. Since the sheet 110 of the drape 100 is fixed to the bag section 120, the position of the sheet 110 is stabilized. Accordingly, the drape 100 can prevent the position of the surgical opening 109 from being shifted from the treatment target site of the patient P during the operation.

  The bag unit 120 is provided on the distal end side in the insertion direction of inserting the hand H into the insertion slot 125, and is a finger holding unit 126 capable of individually holding the fingers f1, f2, f3, f4, and f5 of the patient P. have. Therefore, the patient P can freely move each finger f1, f2, f3, f4, f5 during the operation. Therefore, the drape 100 can further reduce the stress during the operation of the patient P. In addition, the finger holding unit 126 individually holds the fingers f1, f2, f3, f4, and f5, so that it is compared with a case where all the fingers f1, f2, f3, f4, and f5 are held in one space. Thus, the inside of the space 124 can be prevented from getting stuffy.

  In addition, the bag section 120 has a contact portion 128 for bringing the peripheral portion 125a of the insertion port 125 into close contact with the hand H of the patient P. Therefore, in the drape 100, since the contact portion 128 provided in the bag portion 120 brings the peripheral portion 125a of the insertion port 125 into close contact with the vicinity of the wrist of the patient P, various kinds of liquid generated during the operation pass through the insertion port 125. It can be prevented from leaking out of the space 124 through the space 124.

  Further, the sheet 110 has a convex portion 115 that is disposed on the surface 110 a of the sheet 110 so as to surround the periphery of the surgical opening 109 and protrudes in a direction away from the sheet 110. Therefore, the surgeon can use the convex part 115 as a guide part for guiding the movement of the needle part 210 while performing an operation using the drape 100. The surgeon can prevent the insertion position of the needle portion 210 from being shifted by using the convex portion 115 as a guide portion. In addition, the surgeon can perform puncturing with the needle unit 210 while keeping the puncturing angle of the needle unit 210 constant.

  Further, the sheet 110 has a through hole 119 penetrating in the thickness direction of the sheet 110, and the bag portion 120 has a communication hole 129 that communicates the space 124 of the bag portion 120 with the outside of the bag portion 120. I have. The sheet 110 and the bag 120 are arranged such that at least a part of the through hole 119 and at least a part of the communication hole 129 overlap, and the surgical opening 109 is formed by the through hole 119 and the communication hole 129. ing. Therefore, the drape 100 can be manufactured by a simple operation of fixing the sheet 110 in which the through-hole 119 is formed and the bag portion 120 in which the communication hole 129 is formed in the periphery of the surgical opening 109. .

  Further, the sheet 110 can be folded and unfolded while being fixed to the bag section 120. Therefore, the drape 100 can be attached to the patient P, and the drape 100 can be transported and stored in a state where the sheet 110 is compactly folded.

  The surgical opening 109 is arranged at a position where at least a part of the back Hb of the hand H of the patient P is exposed when the seat 110 and the bag 120 are mounted on the patient P. By accessing the upper Hb of the hand H of the patient P via the surgical opening 109, the surgeon can smoothly proceed with the dTRA procedure. In addition, the surgeon uses the drape 100 for a dTRA procedure in which a site having a complicated shape such as the hand H is used as an operation field, so that the position of the surgical opening 109 can be changed from the site to be treated during the operation. The displacement can be suitably prevented.

(Modification of First Embodiment)
Next, a drape 300 according to a modification of the first embodiment will be described. In the description of this modification, a detailed description of the configuration and the like already described in the first embodiment will be omitted.
