Description

  The present invention relates to a surgical pad assembly in which a pad with a pull-out thread used in surgery is held on a backing.

  In the case of a surgical operation, a pad made of non-woven fabric or the like is used for the purpose of hemostasis, absorption of fluid and prevention of damage to body tissue. These pads need to be removed from the patient's body after use, and a withdrawal thread is attached for easy removal.

  Such pads with a pull-out thread are usually placed with a plurality of pad bodies on a backing sheet and packaged together with the backing sheet, so that the pull-out thread is not damaged or tangled during storage or transport. In addition, the draw-out yarn is wound around the backing sheet. In addition, although the base paper is generally made of paper in which holes or cuts are made in cardboard or cardboard, but in the present specification, synthetic resin, wood, bamboo, mineral, metal, glass, ceramic, carbon It shall be of any material such as fiber.

  Patent Document 1 discloses “a surgical absorption sheet base plate” for holding a plurality of surgical absorption sheets. According to the absorption sheet base plate for surgery of Patent Document 1, “each absorption sheet main body of a plurality of absorption sheets for surgery can be sequentially displaced and arranged in parallel on the surface portion, and the state can be maintained, so The number of the surgical absorption sheets can be easily confirmed. ”

JP, 2010-94286, A

  In the case of the absorption sheet base plate for surgery of patent document 1, since the string member is hooked by the incision of a thin plate, it is easy to attach a wrinkle to a drawing thread. If the draw-out yarn is wrinkled, the pull-out yarn becomes bulky and takes up a place during the operation, and thus it becomes a hindrance to the operation.

  Moreover, in the absorption sheet base plate 11 for surgery of patent document 1, the string member 14 is hooked one by one to the some notch 24, and the string member 14 is wound collectively on the some absorption sheet main body 13 arrange | positioned Therefore, when using the surgical absorbent sheet, it is necessary to remove all the wound cord members 14 in the reverse procedure of the wound procedure. Since about 100 to 200 absorption sheets for surgery are used at the time of surgery, it takes a considerable amount of time to remove and prepare the absorption sheet for surgery from the base plate of Patent Document 1. In addition, even if it is attempted to add a surgical absorption sheet for hemostasis when, for example, a sudden bleeding occurs during surgery, it is not possible to quickly remove the surgical absorption sheet from the base plate of Patent Document 1, delaying the hemostasis. Cause an increase in the amount of bleeding and burden the patient.

  The present invention has been made in consideration of the above-described conventional problems, and a surgical pad assembly and a surgical pad assembly that are less likely to be wrinkled and can be quickly and easily removed from a backing than conventional. It is an object of the present invention to provide a backing sheet used for an assembly.

The surgical pad assembly according to the present invention is a surgical pad assembly in which a pad with a pull-out thread used in a surgical operation is held on a mount, and the mount has one or more loosely inserted portions. The pad is held on the mount by loosely inserting the draw-out yarn into the loosely inserted portion more than twice.
The backing according to the present invention is a backing used for the above-mentioned surgical pad assembly.

  In the surgical pad assembly, the loosely inserted portion includes the first loosely inserted portion and the second loosely inserted portion, and the drawn yarn is loosely inserted into the first loosely inserted portion one or more times, and the second loosely inserted portion Preferably, it is inserted one or more times into the

  Further, in the surgical pad assembly, the withdrawal thread starts from the attachment position to the pad and passes through the first loosely inserted portion, so that it slips off from one surface side of the mount to the other surface side. By pulling the second loosely inserted portion, the drawn yarn which has been inserted through the insertion portion is dropped from the other surface side to one surface side, and before and after the pulled yarn is inserted through the first loosely inserted portion, and It is preferable that the variation allowance angle in the advancing direction of the drawn yarn is 90 degrees or less before and after the insertion of the loose fitting portion.

  Also, in the surgical pad assembly, is the idle insertion portion a hole having a width enough to allow insertion of the drawn yarn, or a slit that has a width sufficient to allow the drawn yarn to be inserted loose from the outer edge of the backing sheet? Alternatively, a loose insertion space which is a space large enough to allow the pullout yarn to be loosely inserted, and a slit which is a slit or a gap for guiding the pullout yarn leading from the outer edge of the mount to the loose insertion space It is preferable to have.

  In the surgical pad assembly, the pull-out yarn is folded back from one side to the other side of the backing sheet at a part of the outer edge of the backing sheet to have a direction changing part, and Preferably, a groove is provided in part of the outer edge of the backing.

In the surgical pad assembly, the length of the drawn yarn from the attachment position to the pad to the direction changing portion is preferably 5 cm or more.
A mount used for a surgical pad assembly according to the present invention is characterized in that it is used for the surgical pad assembly.

  The surgical pad assembly according to the present invention and the backing sheet used for the surgical pad assembly are prepared by loosely inserting the drawn yarn into a single loose insertion portion opened in the backing sheet or more, or by opening the backing yarn. Since the pad is held on the mount by loosely inserting the pull-out thread in two or more loosely inserted portions, the pull-out thread is less likely to be wrinkled than in the prior art, and it can be removed quickly and easily from the mount simply by holding the pad.

FIG. 1 is a schematic view showing a surgical pad assembly according to the present invention. It is a dashed-dotted line Z-Z sectional view in FIG. It corresponds to ZZ sectional view of modification 1. It corresponds to ZZ sectional view of modification 2. It corresponds to ZZ sectional view of modification 3. FIG. 18 is a schematic view showing a surgical pad assembly according to a fourth modification.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is a schematic view showing a surgical pad assembly 1 according to the present invention.
The surgical pad assembly 1 is one in which a pad 2 with a withdrawal thread 3 used in a surgical operation is held on a backing sheet 4, and a set of five pads 2 with a withdrawal thread 3 is used in two sets. It is fixed to a mount 4 of a sheet. In addition, after sealing the surgical pad assembly 1 with a packaging material (not shown) such as a resin film, it is sterilized and packaged by sterilizing the inside according to a conventional method.

  The pad 2 is a protective sheet used to immerse physiological saline during surgery such as neurosurgery to prevent damage to body tissue, and is made of a medical gauze laminated with a plurality of non-woven fabrics. The pad 2 is preferably high in water absorbability, and can also be used for hemostasis, wiping of body fluid such as blood, and exclusion of organs.

  Further, the pad 2 is not limited to medical gauze, and may be anything that hardly causes damage to body tissue, and it is desirable to have some degree of flexibility, so for example, natural materials such as cotton, rayon etc. It may be fiber, chemical fiber, and sponge. The shape of the pad 2 is, for example, a rectangle having a width of 5 mm to 30 mm and a length of 5 mm to 60 mm when viewed in plan.

  The pad 2 may also include an object to be sensed remotely by an external sensing device such as an X-ray contrast thread (not shown) or an IC tag (not shown). Here, the X-ray contrast yarn is a chemical fiber containing barium sulfate or the like which is difficult to transmit X-rays, and the IC tag is a very small electronic device that works by receiving radio waves readable by an IC tag reader.

  The pad 2 can be sensed from outside the body even after the operation is completed by using an X-ray contrast thread, an IC tag or the like. For example, when sewing with a sewing machine, by using an X-ray contrast yarn for at least one of the upper thread and the lower thread of a sewing thread, it is not necessary to perform a dedicated operation for attaching the X-ray contrast thread, and the manufacturing cost Is reduced.

  The pull-out yarn 3 is a strong and flexible fiber attached to the pad 2 in order to remove the pad 2 safely from the patient's body. The diameter of the drawing yarn 3 is 0.2 to 2 mm, and the length is 5 to 20 cm.

  The backing sheet 4 is a packing material for winding the drawn yarn 3 and holding the pad 2 so that the drawn yarn 3 is not damaged or entangled during storage or conveyance, and made of paper such as cardboard or cardboard In general, any material may be used as long as it has such a rigidity that it does not deform even when the drawn yarn 3 is wound.

The mount 4 has a pad installation place 5, a first loosely inserted portion 7, a second loosely inserted portion 8 and a direction changing portion 9.
The pad placement site 5 is an area on the backing 4 where the pad 2 is placed. It is preferable that the pad installation place 5 have a projection 6 for positioning the pad 2. The projections 6 can be formed by cutting the mounting position X of the drawn yarn 3 to the pad 2 by cutting the backing sheet, bending a part of the backing sheet, and causing it to protrude from the main surface.

The first loosely inserted portion 7 and the second loosely inserted portion 8 are holes having a size sufficient to allow the drawn yarn 3 to be loosely inserted.
The pad 2 is held on the mount 4 by loosely inserting the draw-out yarn 3 into the one or more loosely inserted portions provided on the mount 4 twice or more. For example, it is preferable that the pull-out yarn 3 be loosely inserted into the first loosely inserted portion 7 one or more times and loosely inserted into the second loosely inserted portion 8 once or more.

  As a result, the draw-out yarn can be loosely inserted at least once into at least two loosely inserted portions opened in the backing sheet 4, and the pad 2 is held on the backing sheet 4 in an appropriately restrained state without being too loose. Can.

  More specifically, as shown in FIG. 2 which is a cross-sectional view taken along the alternate long and short dash line Z-Z in FIG. 1, the draw-out yarn 3 starts from the attachment position X to the pad 2 and passes through the first loosely inserted portion 7 The pull-out yarn 3 which has fallen from one side A of the mount 4 to the other side B and the first loosely inserted portion 7 is inserted through the second loosely inserted portion 8 to form the other side It passes out to one side A side from B side.

  In addition, before and after the lead-out yarn 3 passes through the first free insertion portion 7 and before and after the second free insertion portion 8 is passed, it is preferable that the variation allowable angle of the advancing direction of the pull-out yarn 3 is 90 degrees or less. Thereby, when inserting the 1st free insertion part 7 and the 2nd free insertion part 8, it becomes difficult to get wrinkles to a drawing thread. Here, the fluctuation allowable angle is an allowable value of an angle (hereinafter referred to as a “variation angle”) in a three-dimensional coordinate system formed by the trajectory when the lead-out yarn 3 goes straight and the actual trajectory of the lead-out yarn 3 For example, in the case where the fluctuation angle is 90 degrees, the traveling direction of the drawing yarn 3 is bent at a right angle.

  Moreover, as shown in FIG. 2, it is preferable that the length of the drawing thread 3 from the attachment position X to the pad 2 to the direction change part 9 is 5 cm or more. In FIG. 2, the linear distance from the attachment position X to the pad 2 to the direction changing portion 9 is 5 cm, and when the lead-out yarn 3 is inserted through the first free insertion portion 7 and the second free insertion portion 8 In order to bend, the length of the withdrawal yarn 3 inevitably becomes 5 cm or more.

  As a result, since there is almost no crease in the pull-out yarn 3 between the attachment position X to the pad 2 and the length of 5 cm, the pull-out yarn within 5 cm assumed to be able to enter the surgical field near the affected area during surgery It is not bulky and does not take up a space, and in particular, it becomes difficult to get in the way of treatment.

  The direction changing portion 9 is provided at a part of the outer edge of the mount 4, and the drawn yarn 3 is turned from one side A to the other side B of the mount 4. In the direction changing portion 9, it is preferable that a U-shaped groove or the like is provided in a part of the outer edge of the backing sheet 4.

  Moreover, it is preferable that the length from the attachment position X to the pad 2 to the direction change part 9 is 20 cm or less or the full length of the drawing thread 3 or less. Thereby, storage and conveyance are performed so that the pull-out yarn 3 is hardly wrinkled between the attachment position X to the pad 2 and the length of 20 cm, or the entire length of the pull-out yarn 3 without unnecessarily enlarging the backing sheet 4 It can be performed.

  In addition, as shown in FIG. 3 corresponding to the Z-Z cross-sectional view of the modified example 1, loosely inserting the drawing yarn 3 twice or more in any one of the first loosely inserting portion 7 or the second loosely inserting portion Thus, the pad 2 can be held on the backing sheet 4 without loosely inserting the drawn yarn 3 into another loosely inserted portion. In such a case, the mount 4 may have only one loosely inserted portion, and in FIG. 3, only the first loosely inserted portion 7 is provided.

  Further, as shown in FIG. 4 corresponding to the Z-Z cross-sectional view of the second modification, at one side of the mount 4 including the direction changing portion 9 or the direction changing portion 9, the mount 4 is folded and two or more sheets are stacked. Is preferred. As a result, the thickness of the direction changing portion 9 can be made twice or more that of the backing sheet 4 with a simple structure, and the wrinkles of the drawn yarn 3 in the direction changing portion 9 become even more difficult to stick.

  Further, as shown in FIG. 5 corresponding to the Z-Z sectional view of the third modification, the member 10 thicker than the mount 4 is attached to one side of the mount 4 including the direction change portion 9 or the direction change portion 9 Is preferred. As a result, the thickness of the mount 4 in the direction changing portion 9 can be thicker than that of the mount 4, and it becomes difficult for the direction change portion 9 to wrinkle the drawn yarn 3.

  Further, as shown in FIG. 6 which is a schematic view of the fourth modification, the first loosely inserting portion 7 has a loosely inserting space portion 7 a which is a space having a size sufficient to allow the pull-out yarn 3 to be loosely inserted, It is preferable to have a slit portion 7b which is a cut or a gap for guiding the lead-out yarn lead-in, which continues from the outer edge of the to the loose insertion space portion 7a.

  Thereby, at the time of manufacture, the pull-out yarn 3 can be easily loosely inserted in the first loosely inserted portion 7 by utilizing the slit portion 7 b. Preferably, the slit portion 7 b has a V-shaped notch 7 c on the outer edge side of the backing sheet 4. Thereby, at the time of manufacture, the drawn yarn 3 is easily hooked to the slit portion 7 b.

  Similarly, the second loose insertion portion 8 continues from the outer edge of the mount 4 to the loose insertion space 8a, which is a space having a size large enough to allow the pull-out yarn 3 to be loosely inserted. It is preferable to have the slit part 8b which is a cut | interruption or a clearance gap for guidance.

  Thereby, at the time of manufacture, the pull-out yarn 3 can be easily loosely inserted in the second loosely inserted portion 8 by utilizing the slit portion 8 b. Preferably, the slit portion 8 b has a V-shaped notch 8 c on the outer edge side of the backing sheet 4. Thereby, at the time of manufacture, the drawn yarn 3 is easily hooked to the slit portion 8b.

The shape of the loose insertion space portions 7a and 8a may be any shape as long as it is wide enough to allow the pull-out yarn 3 to be loosely inserted, and is not limited to a circular shape, for example, an oval, semicircular, polygonal, star It may be a mold or the like. The shape of the slits 7b and 8b may be any shape as long as drawing of the draw-out yarn 3 is easy, for example, by making the width of the gap about the same as the diameter of the loose insertion spaces 7a and 8a, The shapes of the first free insertion portion 7 and the second free insertion portion 8 may be wide enough to allow insertion of the drawn yarn and have a slit in the shape of a long hole continuing from the outer edge of the backing sheet 4.
In addition, as long as there is no contradiction in particular, each modification can be combined suitably.

  As described above, according to the surgical pad assembly 1 according to the present invention, the drawn yarn is loosely inserted twice or more into one loosely inserted portion opened on the mount 4 or 2 pieces opened on the mount 4 Since the pad 2 can be held on the mount 4 simply by loosely inserting the pull-out yarn 3 in the above-mentioned loosely-inserted portion, the pull-out yarn 3 is more unlikely to be wrinkled than in the prior art. Can be quickly and easily removed from 4.

Hereinafter, the present invention will be described in detail based on examples. However, the following examples do not limit the present invention, and it is all within the technical scope of the present invention to carry out modifications without departing from the spirit of the present invention.
