Description

[Technical Field]

[0001] The present invention relates to a storage tray for needled sutures used to package needled sutures for medical use. [Background technology]

[0002] Medical needle sutures used in surgical and dental procedures consist of a suture attached to a straight or curved needle, and are generally attached by inserting the suture into a blind hole drilled at the base of the needle and crimping it.

[0003] Sutures with needles stored in a case such as a storage tray are sterilized and then sealed in a packaging bag before being sold as a product. The packaging bag is made of a bacteria-impermeable film or similar material, and is sealed by sandwiching the entire sterilized case and sealing the periphery. Then, during surgery, the packaging bag is opened, and the suture needle is grasped with a needle holder to pull the suture out of the case and use it for suturing.

[0004] Cases for storing sutures with needles are generally made of paper or resin, or storage trays consisting of a resin container with a paper lid attached, and the sutures are stored inside the case wound in a circular, oval, or figure-eight shape.

[0005] Sutures can be wound by hand or machine. When wound manually, for example, the suture is wound around two rods in a figure-eight pattern and then stored in a storage tray. On the other hand, machines can also be used to wind the suture directly into a storage tray made of a plastic container with a paper lid attached.

[0006] 10 is a diagram illustrating a method for winding sutures inside a storage tray. In this case, needle-attached sutures 40 are engaged with the bottom surface 121 of the container member 120, the tip of a suture insertion jig 150 that guides sutures 42 to the vicinity of the bottom surface 121 of the container member 120 is inserted between the container member 120 and the lid member 130, and the storage tray 110 is rotated relative to the suture insertion jig 150, which creates a state similar to that in which the suture insertion jig 150 is moving along the outer periphery of the storage tray 110, and the sutures 42 are wound inside the storage tray 110.

[0007] FIG. 11 is a diagram illustrating the state of needle-attached sutures in a storage tray. In this diagram, the suture 42 is wound in an oval shape around the outside of the fitting posts 122 used to connect the suture 42 to the lid member in the container member 120. When a highly linear suture 42, such as a monofilament thread, is used as the suture 42, the bent suture 42 tends to straighten, causing the suture 42 to easily protrude from the storage tray 110. Therefore, it is common to first attach the lid member to the container member 120 before winding the suture. Naturally, the suture 42 tends to protrude from its tip. However, when the suture 42 is wound in an oval shape as shown in FIG. 11, the suture 42 tends to straighten at the left and right positions of the arc, making it particularly prone to bulging and protruding near the straight portions of the oval shape. Furthermore, since the straight portion of the storage tray 110 and the suture 42 are aligned parallel to each other, the suture 42 is likely to protrude from the storage tray 110 when vibration is applied in this state.

[0008] If the packaging bag is sealed with the suture 42 protruding from the storage tray 110, the protruding suture may become pinched in the seal, resulting in problems such as an inability to guarantee sterilization safety. Fig. 12 is a plan view of a conventional storage tray for preventing protruding sutures, as shown in Patent Document 1. This storage tray 210A comprises a resin container member 220 to which a paper lid member 230 is attached. A plurality of protruding ribs 226 are provided on the inside of a side wall 225 of the container member 220. Cutouts 235 shaped to match the ribs 226 are provided along the outer periphery of the lid member 230. In other words, when the lid member 230 is attached to the container member 220, the ribs 236 fit into the cutouts 235 of the lid member 230. In this way, by providing notches 235 on the outer periphery of lid member 230, a wavy edge portion is formed in the planar direction along the outer periphery of lid member 230, which has the effect of preventing sutures 42 of stored needle-attached sutures 40 from protruding from storage tray 210. Specifically, even if the tip of suture 42 protrudes from the gap between container member 220 and lid member 230, suture 42 is caught in notches 235, thereby preventing the amount of protrusion from the tip. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] U.S. Patent No. 10,835,237 Summary of the Invention [Problem to be solved by the invention]

[0010] However, when performing a thread winding operation using the invention disclosed in Patent Document 1, there is a drawback in that the thread insertion jig 150 or the suture thread 42 is likely to get caught in the notch 235, making it difficult to perform the thread winding operation smoothly.

[0011] In view of the above circumstances, the present invention aims to provide a storage tray for needle-attached sutures that can prevent the suture from protruding during winding and after storage without using a lid member, and that allows for smooth winding work without the suture getting caught.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0018] This embodiment Storage tray 1 Figures 1 to 5 respectively show a top perspective view, a rear perspective view, a plan view, a front view, and a left side view of a storage tray 1 according to this embodiment. Figure 6 shows a top perspective view of a cut model of the storage tray 1 of the present invention taken along line AA shown in Figure 3. Figure 7 shows a top view of the storage tray 1 of the present invention containing needle-equipped sutures.

[0019] The storage tray 1 is a tray for storing needled sutures 61, each having a suture needle 62 attached to the end of the suture 63, wound into a circle by passing it through a tunnel 70, and after storing it, the entire suture is wrapped and sealed in a bacteria-impermeable film or the like. Note that "winding the suture 63 into a circle" includes winding it into an oval or ellipse, in addition to a perfect circle, to match the shape of the storage tray 1.

[0020] The overall planar shape of the storage tray 1 can be a rectangle with rounded corners, an ellipse, an oval whose periphery is made up of arcs and straight lines, an oval shape with opposing straight lines narrowed, or a rectangle with rounded corners and narrow straight lines. An oval shape with opposing straight lines narrowed is similar to the shape of a snowboard. In other words, when the storage tray 1 is placed horizontally, the left and right sides form arcs such as semicircles, and the top and bottom parts have a curved outer periphery that narrows so that they approach each other.

[0021] The storage tray 1 according to this embodiment is basically made of resin, and has the shape of a shallow vessel having a bottom surface 30 and a tunnel 70 arranged so as to surround the bottom surface 30.

[0022] The bottom surface 30 is provided with a suture needle locking portion 60 for locking a suture needle 62 of a needle-attached suture 61. The suture needle locking portion 60 is only required to be able to hook and fix the suture needle 62, so it may be a locking portion formed integrally with the storage tray 1, or it may be a separate base plate that is placed on the bottom surface 30 and into which the tip of the suture needle can be inserted and fixed.

[0023] The inner wall 40 has an inner wall opening 41. The inner wall opening 41 is defined by the inner wall 40 being disposed so as to partially surround the bottom surface 30. The suture 63 extending from the suture needle 62 locked in the suture needle locking portion 60 passes through the inner wall opening 41 and is accommodated in a tunnel 70 adjacent to the inner wall opening 41.

[0024] Tunnel 70 The tunnel 70 is defined by a plurality of upper support portions 10, a plurality of lower support portions 20, an inner wall 40, and an outer wall 50. The plurality of upper support portions 10, the plurality of lower support portions 20, the outer wall 50, and the inner wall 40 form a space 72 that accommodates the suture 63.

[0025] An open compartment 80 is provided between one end and the other end of tunnel 70. Open compartment 80 exposes outer wall openings 51 located at both ends of tunnel 70. Open compartment 80 communicates with the inside of inner wall 40 through inner wall opening 41. Thus, suture 63 is housed within tunnel 70 from inner wall opening 41 through open compartment 80. Open compartment 80 may include a compartment floor 80a extending parallel to bottom surface 30.

[0026] The tunnel 70 may have multiple sub-tunnels 71. Each of the multiple sub-tunnels 71 is also defined by multiple upper supports 10, multiple lower supports 20, an inner wall 40, and an outer wall 50. A secondary open section 81 is provided between each sub-tunnel 71 along the entire length of the tunnel 70. Therefore, in a storage tray 1 having multiple sub-tunnels 71, the number of sub-tunnels 71 is the same as the sum of the number of open sections 80 and the number of secondary open sections 81.

[0027] The secondary open compartment 81 may include a secondary compartment floor 81 a extending parallel to the bottom surface 30 .

[0028] The tunnel 70 according to this embodiment includes four sub-tunnels 71, but is not limited to this.

[0029] inner wall 40 Inner wall 40 may have a shape that rises at a right angle from the outer periphery (edge) of bottom surface 30, or may have a curved shape such as an arc in plan view. The height of inner wall 40 is sufficient to accommodate wound suture thread 63, and is therefore less than 1 cm.

[0030] The inner wall 40 has a first inner wall surface 40a facing the outer wall 50, an inner wall top 40b located vertically distal to the surface 31 of the bottom surface 30, a second inner wall surface 40c facing the inside of the storage tray 1, and an inner wall bottom 40d located opposite the inner wall top 40b.

[0031] The inner wall 40 may have a plurality of inner wall openings 41. One of the plurality of inner wall openings 41 communicates with the open section 80, and each of the remaining inner wall openings 41 communicates with a secondary open section 81. The storage tray 1 may have inner walls 40 corresponding to each of the plurality of sub-tunnels 71.

[0032] In the storage tray 1 according to this embodiment, the four sub-tunnels 71 share one inner wall 40, but this is not limitative.

[0033] Exterior wall 50 The outer wall 50 is positioned outside the inner wall 40 so as to face the inner wall 40. The outer wall 50 may be parallel to the inner wall 40. The shape of the outer wall 50 in a plan view may be the same as the shape of the inner wall 40 or may be a different shape (e.g., rectangular). The height of the outer wall 50 is preferably the same as the height of the inner wall 40, but may be different.

[0034] The outer wall 50 has a first outer wall surface 50a facing the inner wall 40, an outer wall top 50b positioned vertically distal to the surface 31 of the bottom surface 30, a second outer wall surface 50c facing the outside of the storage tray 1, and an outer wall bottom 50d positioned opposite the outer wall top 50b.

[0035] The outer wall 50 may have one or more outer wall openings 51 in the open section 80 and / or the secondary open section 81. The outer wall openings 51 connect the space 72 to the outside of the tunnel 70. By providing the outer wall openings 51 in the outer wall 50, the open section 80 and / or the secondary open section 81 communicate with the outside of the outer wall 50 through the outer wall openings 51. Furthermore, by providing the outer wall openings 51 in the open section 80 and / or the secondary open section 81 in the outer wall 50, interference by the outer wall 50 with the suture insertion jig 90 (described later) is avoided, making it easier to store the suture 63 in the tunnel 70 using the suture insertion jig 90. The storage tray 1 according to this embodiment may have an outer wall 50 separated by multiple outer wall openings 51.

[0036] In the storage tray 1 according to this embodiment, the outer wall openings 51 corresponding to the one open compartment 80 and the three sub-open compartments 81 are not limited to these.

[0037] Upper support part 10 The upper support members 10 are disposed more distally than the lower support members 20 relative to the surface 31 of the bottom face 30, with one end of each of the upper support members 10 connected to the first inner wall surface 40a of the inner wall 40 and the other end of each of the upper support members 10 connected to the first outer wall surface 50a of the outer wall 50. In one embodiment, one end of each of the upper support members 10 is connected to the first inner wall surface 40a on the inner wall top 40b side, and the other end of each of the upper support members 10 is connected to the first outer wall surface 50a on the outer wall top 50b side.

[0038] In one embodiment, each of the plurality of upper support portions 10 extends perpendicular to the first inner wall surface 40a of the inner wall 40. In another embodiment, each of the plurality of upper support portions 10 extends perpendicular to the first outer wall surface 50a of the outer wall 50. In yet another embodiment, each of the plurality of upper support portions 10 extends perpendicular to the first inner wall surface 40a of the inner wall 40 and also perpendicular to the first outer wall surface 50a of the outer wall 50.

[0039] Lower support part 20 The lower support members 20 are disposed closer to the bottom surface than the upper support members 10, and one end of each of the lower support members 20 is connected to the first inner wall surface 40a of the inner wall 40, and the other end of each of the lower support members 20 is connected to the first outer wall surface 50a of the outer wall 50. In one embodiment, one end of each of the lower support members 20 is connected to the first inner wall surface 40a on the inner wall bottom 40d side, and the other end of each of the lower support members 20 is connected to the first outer wall surface 50a on the outer wall bottom 50d side.

[0040] In one embodiment, each of the plurality of lower support portions 20 extends perpendicular to the first inner wall surface 40a of the inner wall 40. In another embodiment, each of the plurality of lower support portions 20 extends perpendicular to the first outer wall surface 50a of the outer wall 50. In yet another embodiment, each of the plurality of lower support portions 20 extends perpendicular to the first inner wall surface 40a of the inner wall 40 and also perpendicular to the first outer wall surface 50a of the outer wall 50.

[0041] A plurality of inner wall ribs 42 The first inner wall surface 40a of the inner wall 40 may include a plurality of inner wall ribs 42 extending between the inner wall top portion 40b and the inner wall bottom portion 40d and protruding toward the lumen of the tunnel 70. The cross-sectional shape of each of the plurality of inner wall ribs 42 cut perpendicular to the direction between the inner wall top portion 40b and the inner wall bottom portion 40d may be semicircular. The plurality of inner wall ribs 42 reinforce the inner wall 40 and enable the suture 63 to be smoothly stored in the storage tray 1 by reducing the contact area between the suture insertion jig 90 (described below) and the inner wall 40.

[0042] a plurality of exterior wall ribs 52 The first outer wall surface 50a of the outer wall 50 may include a plurality of outer wall ribs 52 extending between an outer wall top portion 50b and an outer wall bottom portion 50d and protruding toward the lumen of the tunnel 70. The cross-sectional shape of each of the plurality of outer wall ribs 52 cut perpendicular to the direction between the outer wall top portion 50b and the outer wall bottom portion 50d may be semicircular. The plurality of outer wall ribs 52 reinforce the outer wall 50 and enable smooth storage of the suture 63 in the storage tray 1 by reducing the contact area between the suture insertion jig 90 (described below) and the outer wall 50.

[0043] Upper rib 11 Each of the multiple upper support parts 10 may include an upper rib 11 that extends between the inner wall 40 and the outer wall 50 and protrudes toward the lumen of the tunnel 70. The cross-sectional shape of the upper rib 11 cut perpendicular to the direction between the inner wall 40 and the outer wall 50 may be semicircular. The upper rib 11 reinforces the upper support part 10 and also enables the suture 63 to be smoothly stored in the storage tray 1 by reducing the contact area between the suture insertion jig 90 (described below) and the upper support part 10.

[0044] Lower rib 21 Each of the multiple lower support portions 20 may include a lower rib 21 extending between the inner wall 40 and the outer wall 50 and protruding toward the lumen of the tunnel 70. The cross-sectional shape of the lower rib 21 cut perpendicular to the direction between the inner wall 40 and the outer wall 50 may be semicircular. The lower rib 21 reinforces the lower support portion 20 and also enables the suture 63 to be smoothly stored in the storage tray 1 by reducing the contact area between the suture insertion jig 90 (described below) and the lower support portion 20.

[0045] Thread insertion jig 90 8A, 8B, and 8C show a plan view (FIG. 8A), a front view (FIG. 8B), and a plan view (FIG. 8C) of a thread insertion jig 90 used as an example in the storage tray 1 of the present invention, a cross-sectional view (FIG. 8D) of the thread insertion jig 90 cut along line CC shown in FIG. 8C, and a perspective view (FIG. 8E), and an enlarged view (FIG. 8F) of the thread insertion jig 90 in region B shown in FIG. 8B.

[0046] The suture insertion jig 90 according to this embodiment has a hook portion 91 at its tip. The hook portion 91 of the suture insertion jig 90 according to this embodiment can hook the suture 63. The suture insertion jig 90 according to this embodiment has a rod-like shape, but may have another shape (e.g., a curved shape). The suture insertion jig 90 according to this embodiment may be made of resin or rubber.

[0047] 9A to 9D show steps for using a suture insertion tool 90 to store sutures 63 in two tunnels 70 of a storage tray 1 of the present invention. First, the suture insertion tool 90 is inserted into the first tunnel 70 from the hook portion 91 side, and the suture 63 is hooked onto the hook portion 91 (FIG. 9A). Second, the suture insertion tool 90 is withdrawn from the first tunnel 70, allowing the suture 63 to be stored in the first tunnel 70 (FIG. 9B).
