Description

[Technical Field]

[0001] The present invention relates to a suture needle counter used when disposing of used suture needles. [Background technology]

[0002] In surgical operations and the like, it is essential to accurately track the number of used suture needles so that the needles used in the operation are not left behind inside the patient's body.

[0003] Conventionally, when disposing of used suture needles, a known method is to attach the used suture needles to a suture needle counter and dispose of them in order to accurately count the number of used suture needles and to properly dispose of them as medical waste.

[0004] Various structures of such suture needle counters are known, but for example, as shown in Patent Document 1, a surgical suture needle counter is known which is an instrument for counting and disposing of used surgical suture needles, and which consists of a main body and a lid, with absorbent acrylic foam attached to the inside surface of the main body to hold the needles in place, with counting numbers displayed on the surface of the absorbent acrylic foam, and the lid made of transparent resin, with the needles being fixed between the absorbent acrylic foam and the lid when closed.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-126097 Summary of the Invention [Problem to be solved by the invention]

[0006] Generally, in surgical procedures, the suture needles used by the surgeon are held at the tip of a needle holder beforehand and handed over to the surgeon by a nurse while still attached to the needle holder. After use, the suture needles are also handed over from the surgeon to the nurse while still held at the tip of the needle holder. The nurse attaches the used suture needle to a suture needle counter and discards the used needle along with the suture needle counter.

[0007] As mentioned above, the suture needles used by the surgeon are attached to the tip of a needle holder and handed to the surgeon by the nurse, but it is necessary to be able to immediately hand over the appropriate suture needle depending on the surgical procedure. For this reason, it is necessary to have the appropriate suture needle attached to the tip of the needle holder in advance and keep it waiting on an instrument table or the like in the operating room.

[0008] Conventionally, in surgical operations and the like, in order to keep a needle holder with an unusable suture needle attached, the tip of the needle holder may be leaned against the edge of the cover of a surgical suture needle counter, as shown in Patent Document 1. However, since suture needles that are generally curved in a roughly semicircular shape are often used, leaving a needle holder with a suture needle attached leaning against the edge as described above means that the tip of the suture needle will be left facing upwards, which poses a safety problem.

[0009] In addition, there are cases where a needle holder with a suture needle attached is placed against the edge of a petri dish or the like, and then the tip of the needle holder is covered with a lid of the petri dish or the like and left on standby. However, while a simple cover can hide the tip of the needle holder, it cannot be kept securely in place and is not an adequate safety measure. Furthermore, in order to place the needle holder on a stand, an unnecessary instrument such as a petri dish must be used. For this reason, there has been a demand from medical professionals to reduce the number of instruments placed on instrument stands as much as possible and make effective use of space.

[0010] Therefore, the present invention was made in consideration of the above matters, and its objective is to provide a suture needle counter that can accurately count the number of used suture needles and properly dispose of them as medical waste, and can safely store needle holders with suture needles attached. [Means for solving the problem]

[0011] The present invention has been made to achieve the above object and has the following features.

[0012] The suture needle counter according to the present invention is a suture needle counter for keeping track of the number of surgical suture needles that have been used, and is composed of a main body and a lid that can be opened and closed freely by a hinge structure, the main body having a bottom surface and a plurality of main body side walls that extend in a height direction from the bottom surface and surround the periphery of the bottom surface, and at least one of the main body side walls has a main body side wavy edge that is wavy in a height direction. The lid portion includes a ceiling portion and a plurality of lid side walls extending in a height direction from the ceiling portion and surrounding the periphery of the ceiling portion, and the lid side walls are formed with lid side corrugated edges corresponding to the body side corrugated edges. It is characterized by the following.

[0013] In the suture needle counter according to the present invention, it is preferable that the main body side wave-shaped edge portion has at least one valley portion and peak portions located on both the left and right sides of the valley portion.

[0015] In the suture needle counter of the present invention, the hinge structure preferably comprises a pin portion and a tubular portion, the pin portion being formed on either the main body portion or the lid portion, and the tubular portion being formed on the other of the main body portion or the lid portion, and the pin portion and the tubular portion preferably being detachably engaged in the axial direction of the pin portion.

[0016] In the suture needle counter according to the present invention, it is preferable that the cover portion includes a sponge sheet having predetermined numbers thereon.

[0017] In the suture needle counter according to the present invention, it is preferable that the main body portion includes a magnetic sheet.

[0018] In the suture needle counter according to the present invention, it is preferable that the cylindrical portion has a window portion through which the pin portion can be seen from the outside.

[0019] The above summary of the invention does not list all of the features necessary for the present invention, and subcombinations of these features may also constitute inventions. [Effects of the Invention]

[0020] The suture needle counter of the present invention allows the number of used suture needles to be accurately counted and disposed of appropriately as medical waste, and the wavy edges formed on the side walls of the main body allow the needle holder with the attached suture needle to be safely placed on standby. Furthermore, the suture needle counter of the present invention has a detachable hinge structure and can be separated into the main body and the lid, thereby saving space and allowing it to be placed appropriately even on an instrument stand or the like with limited space.

[0022] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0023] FIG. 1 is a perspective view showing the suture needle counter of this embodiment in a closed state, FIG. 2 is a perspective view of the suture needle counter shown in FIG. 1 from a different angle, FIG. 3 is a perspective view showing the suture needle counter of this embodiment in an open state, FIG. 4 is a perspective view of the suture needle counter shown in FIG. 3 from a different angle, FIG. 5 is a front view of the suture needle counter shown in FIG. 3 as seen from the depth direction, FIG. 6 is an enlarged view of portion C of FIG. 4, and FIG. 7 is a perspective view for explaining a method of attaching and detaching the main body and lid of the suture needle counter of this embodiment.

[0024] In this specification, the height direction, width direction, and depth direction are defined as the directions of the arrows shown in Fig. 1. Also, in this specification, the front side in the depth direction and the back side in the depth direction are defined as the directions of the arrows shown in Fig. 1.

[0025] As shown in Figures 1 to 4, the suture needle counter 1 according to this embodiment is made up of a main body 2 and a lid 3. The main body 2 and lid 3 are configured to be able to open and close freely by a hinge structure made up of a pin 24 and a tube 44, which will be described later. In this specification, the state in which the main body 2 and lid 3 are closed, as shown in Figures 1 and 2, is defined as the closed state of the suture needle counter 1, and the state in which the main body 2 and lid 3 are open, as shown in Figures 3 and 4, is defined as the open state of the suture needle counter 1.

[0026] The main body 2 is a generally rectangular box-shaped member that is open at the top as viewed in Figure 3 and is made of a resin material such as polypropylene. The main body 2 includes a bottom surface 10 and a plurality of main body side walls 20 that extend from the bottom surface 10 in the height direction and surround the periphery of the bottom surface 10.

[0027] As an example, bottom surface 10 is formed in a rectangular shape. Furthermore, the surface of bottom surface 10 that faces outward when suture needle counter 1 is in the closed state is formed flat. Therefore, when suture needle counter 1 is placed on an instrument stand or the like, it can be placed stably without rattle. Furthermore, a magnetic sheet (not shown) may be attached to the surface of bottom surface 10 that faces inward when in the closed state. With such a magnetic sheet, used suture needles can be attracted and fixed by magnetic force as needed, regardless of the size of the suture needle.

[0028] The body side wall 20 is formed to tightly surround the periphery of the bottom surface 10. In addition, the connection portions between adjacent body side walls 20 and the connection portion between the body side wall 20 and the bottom surface 10 are preferably formed as curved surfaces to avoid sharp corners on the outside. In addition, it is preferable that the edge of the body side wall 20 be formed with a body side step 22 that fits into a lid side step 42, which will be described later.

[0029] For example, as shown in FIG. 3, the main body side step portion 22 is formed in a stepped shape such that the edge portion located on the outside is lower than the edge portion located on the inside.

[0030] 4 and 7, a pin portion 24 constituting a hinge structure is formed on one side of the main body side wall 20 extending in the depth direction. The pin portion 24 is formed near both ends in the depth direction of the main body side wall 20. The two pin portions 24 formed near both ends in the depth direction extend toward either the front side or the back side in the depth direction.

[0031] As shown in FIG. 3, it is preferable that a stopper receiving portion 23 that engages with a stopper portion 43, which will be described later, is formed on the other side of the main body side wall 20 that extends in the depth direction.

[0032] The stopper receiving portion 23 is formed in the approximate center of the main body side wall 20 extending in the depth direction, and has a stepped portion recessed inward.

[0033] At least one of the body side walls 20 is formed with a body side corrugated edge 21. It is most preferable that the body side corrugated edge 21 be formed on the body side wall 20 that extends in the width direction and is located on the near side in the depth direction, and it is more preferable that the body side wall 20 that extends in the depth direction and has the stopper receiving portion 23. The body side corrugated edge 21 may also be formed on the body side wall 20 that extends in the width direction and is located on the far side in the depth direction.

[0034] As shown in FIG. 5, the body-side corrugated edge portion 21 is corrugated in the height direction and has at least one valley portion 21a. Furthermore, at least one peak portion 21b is provided on either the left or right side of the valley portion 21a. As shown in FIG. 5, the body-side corrugated edge portion 21 is preferably formed so that the height H1 from the inner surface of the bottom portion 10 to the bottom A of the valley portion 21a is, for example, 13 mm or more, and more preferably 13 mm to 15.1 mm. The body-side corrugated edge portion 21 is preferably formed so that the height H2 from the inner surface of the bottom portion 10 to the apex B of the peak portion 21b is, for example, 20.9 mm or more, and more preferably 20.9 mm to 23 mm. The widthwise dimension W between the apexes B of adjacent peak portions 21b is, for example, preferably 14.1 mm or more, and more preferably 14.1 mm to 17.3 mm. Moreover, the arc shape of the valley portion 21a is preferably formed to have an arc shape that is, for example, an arc of 20 mm diameter taken out at a rate of 1 / 4 or 1 / 3 of the length of the entire circumference.

[0035] 5 shows as an example a case where the body-side corrugated edge 21 is formed on the body side wall 20 that extends in the width direction and is located on the near side in the depth direction, but the configurations of the valleys 21a and peaks 21b are similar when the body-side corrugated edge 21 is formed on the other body side walls 20. Also, while FIG. 5 shows as an example a case where one valley 21a is formed on the body side wall 20, the number of valleys 21a is not limited to this, and multiple valleys 21a may be formed on one body side wall 20, as in the perspective view of FIG. 11 showing a suture needle counter 1 according to another embodiment in an open state.

[0036] In this embodiment, the main body side wavy edge portion 21 has been described as having a waveform in which a series of arc-shaped curves are formed, but the shape of the main body side wavy edge portion 21 is not limited to this, and may be, for example, a triangular wave in which a series of triangles are formed, a rectangular wave in which a series of squares are formed, or a combination of these.

[0037] Furthermore, when the main body side wave-shaped edge portion 21 is formed on the main body side wall body 20 that extends in the depth direction and has the stopper receiving portion 23, it is preferable that the peak portion 21b be formed at the position closest to the depth direction, as shown in Figures 3 and 4.

[0038] The lid 3 is a generally rectangular box-shaped member that is open at the top as viewed in Figure 3 and is made of a resin material such as polypropylene. The lid 3 includes a ceiling 30 and a plurality of lid side walls 40 that extend in the height direction from the ceiling 30 and surround the periphery of the ceiling 30.

[0039] As an example, ceiling portion 30 is formed in a rectangular shape corresponding to bottom portion 10. Furthermore, ceiling portion 30 is formed so that the surface that faces outward when suture needle counter 1 is in the closed state is flat. Therefore, when suture needle counter 1 is placed on an instrument stand or the like, it can be placed stably without rattle. Furthermore, a sponge sheet 31 is attached to the surface of ceiling portion 30 that faces inward when in the closed state.

[0040] The sponge sheet 31 is a flat member corresponding to the size of the ceiling portion 30 and is formed, for example, from a material such as foamed polyethylene resin. Used suture needles are inserted into the sponge sheet 31 to securely hold them. Therefore, the sponge sheet 31 is set to a predetermined hardness and thickness to facilitate insertion of used suture needles while preventing them from easily falling out. A plurality of frame lines, each separated by a predetermined size, are printed on the surface of the sponge sheet 31, and a number is printed inside each frame line. The numbers printed on the surface of the sponge sheet 31 are preferably printed so that they are oriented correctly from the perspective of a nurse when the front side of the suture needle counter 1 in the depth direction is placed on the side of the nurse who will be handing over the needle holder. With this sponge sheet 31, used suture needles can be inserted one by one into the frame lines marked with smaller numbers, allowing the number of used needles to be accurately and visually confirmed.

[0041] The lid side wall 40 is formed to tightly surround the periphery of the ceiling portion 30. In addition, the connection portions between adjacent lid side walls 40 and the connection portion between the lid side wall 40 and the ceiling portion 30 are preferably formed with curved surfaces so as to avoid sharp corners on the outside. In addition, it is preferable that the edge of the lid side wall 40 be formed with a lid side step 42 that fits into the body side step 22.

[0042] As shown in FIG. 3, the cover-side step 42 is formed in a stepped shape so that the edge located on the outside is higher than the edge located on the inside, so as to correspond to the body-side step 22.

[0043] With such body-side step portion 22 and lid-side step portion 42, when suture needle counter 1 is in the closed state, body-side step portion 22 and lid-side step portion 42 fit together, increasing the contact area between them. Therefore, when suture needle counter 1 is in the closed state, even a thin, sharp suture needle can be prevented from protruding to the outside from the gap between body portion 2 and lid portion 3.

[0044] 4 and 6, a tubular portion 44 constituting a hinge structure is formed on one side of the lid side wall 40 extending in the depth direction. The tubular portions 44 are formed near both ends in the depth direction of the lid side wall 40 so as to correspond to the pin portions 24 formed on the main body side wall 20. The two tubular portions 44 formed near both ends in the depth direction are formed in a tubular shape with a hole depth facing either the front side or the back side in the depth direction so as to correspond to the pin portions 24.

[0045] The cylindrical portion 44 allows the pin portion 24 to be rotatably inserted. The cylindrical portion 44 is also formed so that the pin portion 24 can be inserted and removed freely. As shown in Fig. 6, the cylindrical portion 44 preferably has a window portion 44a formed by cutting out a part of the cylindrical edge. With such a window portion 44a, even when the pin portion 24 is inserted into the cylindrical portion 44, the pin portion 24 can be seen from the outside through the window portion 44a.

[0046] As shown in FIG. 6, it is preferable that a marking 24 a representing an arrow or the like indicating the direction in which the pin portion 24 can be pulled out of the cylindrical portion 44 be provided near the pin portion 24 .

[0047] With such a tubular portion 44 and engraving 24a, it is easy to recognize that the hinge structure consists of the tubular portion 44 and the pin portion 24, and that the pin portion 24 can be pulled out from the tubular portion 44, making it easy to separate the main body portion 2 and the lid portion 3.

[0048] As described above, the body-side step 22 is formed in a stepped shape such that the outer edge is lower than the inner edge, so that when connecting the body 2 and the lid 3, as shown in Fig. 7, the pin 24 can be inserted into the tube 44 after the tube 44 is guided by contacting it with the body-side step 22, making it possible to easily connect the body 2 and the lid 3.

[0049] Preferably, a stopper portion 43 that engages with the stopper receiving portion 23 is formed on the other side of the lid side wall 40 that extends in the depth direction, as shown in FIG.

[0050] Stopper portion 43 has a protrusion that protrudes inward at the tip in the height direction. Stopper receiving portion 23 has a step that corresponds to the protrusion of stopper portion 43, so stopper portion 43 and stopper receiving portion 23 engage with each other when suture needle counter 1 is in the closed state, and suture needle counter 1 can be maintained in the closed state.

[0051] 3 and 5, the lid-side wall 40 is formed with a lid-side corrugated edge portion 41 that corresponds to the body-side corrugated edge portion 21. The lid-side corrugated edge portion 41 has peaks 41b that correspond to the valleys 21a of the body-side corrugated edge portion 21, and valleys 41a that correspond to the peaks 21b of the body-side corrugated edge portion 21.

[0052] Next, a method for making a needle holder with a suture needle attached stand by using the suture needle counter 1 according to the present invention will be described.

[0053] Fig. 8 is a perspective view showing a state in which a needle holder having a suture needle attached thereto is placed on standby using the suture needle counter according to this embodiment, Fig. 9 is a perspective view of the suture needle counter and needle holder shown in Fig. 8 viewed from a different angle, and Fig. 10 is a perspective view showing a state in which a needle holder having a suture needle attached thereto is placed on standby using the main body of the suture needle counter according to this embodiment. Note that the following explanation will be given using as an example a case in which the needle holder 5 is placed against the main body side wall body 20 that extends in the width direction and is located on the near side in the depth direction.

[0054] The suture needle 4 that is placed on standby using the suture needle counter 1 according to the present invention has a substantially semicircular arc shape, as shown in Fig. 9, and as an example, a suture needle 4 with a needle length of approximately 25 to 49 mm is used. The suture needle 4 is placed on standby while attached to the tip of a needle holder 5. Note that in this specification, the suture needle 4 is described as having a substantially semicircular arc shape, but the shape of the suture needle 4 is not limited to this, and it may also be an arc shape that is 5 / 8, 3 / 8, 1 / 4, 1 / 5, etc. of the length of the entire circumference. Furthermore, the shape of the suture needle 4 is not limited to an arc shape and may be a straight shape.

[0055] As an example, the needle holder 5 that is kept on standby using the suture needle counter 1 according to the present invention is a Mathieu-type needle holder 5 with a total length of approximately 140 to 240 mm, as shown in Figure 8. Note that, although the needle holder 5 is described in this specification as being a Mathieu-type needle holder, the type of needle holder 5 is not limited to this, and it may also be a Hegar-type needle holder. Furthermore, the total length of the needle holder 5 may also be outside the range of the total length described above.

[0056] To keep the needle holder 5 with the suture needle 4 attached to its tip on standby, as shown in Figure 8, part of the needle holder 5 is placed against the valley 21a of the main body side corrugated edge 21 so that the suture needle 4 is positioned inside the main body side wall 20. At this time, the needle holder 5 is tilted so that the tip side is higher than the handle side. In addition, because the bottom A of the valley 21a is formed at a predetermined height H1 from the inner surface of the bottom surface 10, the suture needle 4 does not come into contact with the inner surface of the bottom surface 10.

[0057] Furthermore, since ridges 21b are formed on both the left and right sides of the valley 21a, the needle holder 5 can be placed on standby with the needle tip of the suture needle 4 positioned inside the ridges 21b in the depth direction.

[0058] Furthermore, the main body side waved edge 21 formed on the main body side wall 20 extending in the depth direction and having the stopper receiving portion 23 has a peak 21b formed at the frontmost position in the depth direction. Therefore, as shown in Figure 10, even when the needle holder 5 is placed against the main body side wall 20 extending in the depth direction, the needle tip of the suture needle 4 attached to the needle holder 5 will not come into contact with the main body side wall 20 extending in the width direction.

[0059] Furthermore, since the apex B of the peak portion 21b is formed at a height that is a predetermined height H2 from the bottom A of the valley portion 21a, the needle holder 5 can be kept waiting with the height of the tip of the suture needle 4 lower than the height of the apex B, preventing nurses and others from accidentally touching the tip of the suture needle 4.

[0060] Furthermore, the suture needle counter 1 according to the present invention is used by placing it with the front side in the depth direction facing the nurse so that the numbers printed on the surface of the sponge sheet 31 face in the correct direction when viewed from the nurse who is handing over the needle holder 5. Furthermore, the main body corrugated edge 21 is most suitably formed on the main body side wall 20, which extends in the width direction and is located on the front side in the depth direction. Therefore, the needle holder 5 with the suture needle 4 attached can be leaned against the nurse's side, allowing the needle holder 5 to be smoothly handed over.

[0061] Furthermore, the hinge structure of the suture needle counter 1 according to the present invention is configured so that the pin portion 24 is detachable from the tube portion 44, and so the main body portion 2 and the cover portion 3 can be used separately. Therefore, as shown in Figure 10, the needle holder 5 can be placed on standby with only the main body portion 2 separated, and can be used by placing it appropriately on an instrument stand or the like where space is limited.

[0062] In this embodiment, the pin portion 24 is formed on the main body portion 2 and the tubular portion 44 is formed on the lid portion 3. However, the positions at which the pin portion 24 and the tubular portion 44 are formed are not limited to this. The pin portion 24 may be formed on the lid portion 3 and the tubular portion 44 may be formed on the main body portion 2. In this embodiment, the bottom surface portion 10 and the ceiling portion 30 are formed in a rectangular shape. However, the shapes of the bottom surface portion 10 and the ceiling portion 30 are not limited to this. They may be formed in a polygonal shape other than a square, or may have curved sides. In this embodiment, the ceiling portion 30 is formed in a shape corresponding to the bottom surface portion 10. However, the shapes of the bottom surface portion 10 and the ceiling portion 30 may be different from each other. In this case, the main body side wall 20 and the lid side wall 40 may be formed to be inclined. It is clear from the claims that such modified or improved embodiments are also within the technical scope of the present invention. [Explanation of symbols]
