Description

Bone screw package

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a bone screw package.

Background

Bone screws are commonly used for fixing damaged bones in bone surgery, and as a common medical instrument for bone surgery, plastic-sealed sterile packaging bags are generally used for sterile packaging. Because the bone screw diameter and the length and other size requirements of different bone trauma operations are different, a large movable space is reserved in the sterile packaging bag in order to facilitate the sterile packaging bag to accommodate bone screws with different sizes. The sterile packaging bag does not have a good limiting function on the bone screw, especially for smaller-sized bone screws. In the transportation process and the like, the bone screw and the sterile packaging bag are often rubbed and collided due to jolt and shake.

Because the cutting edge of the thread part of the bone screw is sharp, the bone screw can easily generate grinding action with the sterile packaging bag for a long time to form plastic scraps, so that the plastic scraps are implanted into a patient along with the bone screw during operation, and unexpected additional damage is caused to the patient. In addition, the aseptic packaging bag is easy to puncture by the bone screw, so that the aseptic environment of the bone screw is damaged, the bone screw cannot be directly used for clinical operation, and the process treatments such as sterilization, packaging and the like are required to be carried out again in a factory, so that the platform matching efficiency is reduced. In addition, long-term friction between the bone screw and the sterile packaging bag can also cause the bone screw to look stale, affecting the use experience of the clinician.

Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present utility model, the present utility model is described in detail below with reference to the accompanying drawings and detailed description.

Embodiments of the present utility model provide a bone screw package for packaging bone screws 40, the bone screws 40 including, but not limited to, cancellous bone screws, cortical bone screws, bone pegs, cannulated screws, and the like, and the specific type of bone screw 40 packaged is not limited herein. Referring to fig. 1 to 5, the bone screw package according to the embodiment of the present utility model includes a packing box 10 and a supporting member 30.

The packing box 10 is an external packing structure of the bone screw package, and may take various shapes and various structures according to actual needs. Alternatively, the package 10 may have a pocket 11, and the pocket 11 may be used to insert or remove bone screws 40. Optionally, a sealing member 20 for sealing the box opening 11 may be further disposed at the box opening 11. For example, the mouth 11 of the packing box 10 may be sealed by the sealing member 20, so that the inside of the packing box 10 can maintain a sterile environment to some extent, and a sterile package of the bone screw 40 is formed.

A support member 30 is provided within the package 10. The supporting member 30 is provided with a limiting area 32, the limiting area 32 is provided with a through notch 31, and the notch 31 is divided into at least part of the limiting area 32 to form a folded piece 33. The flap 33 can be folded over relative to the limit area 32 to change the opening area of the incision 31, and the flap 33 can limit the bone screw 40 inserted into the incision 31.

Alternatively, the flap 33 may have a root portion and a tip portion, the flap 33 may be connected to other portions of the support member 30 by the root portion, the flap 33 may be configured to be folded along the root portion, and the tip portion of the flap 33 may be configured to be abutted against the bone screw 40 inserted into the cutout 31. In this way, friction force can be generated between the bone screw 40 and the folded piece 33, and clamping fit can be formed between the folded piece 33 and the external thread structure of the bone screw 40, so that the purpose of limiting the bone screw 40 is achieved.

Alternatively, the stop zone 32 may have a distinct demarcation line with other areas of the support member 30. For example, when the limit region 32 is formed on one side surface of the support member 30, the limit region 32 is defined on the whole side surface, and the edge line of the side surface is defined as the boundary between the limit region 32 and the other region.

Alternatively, the spacing area 32 may not have a distinct line of demarcation with other areas of the support member 30. For example, when the limit area 32 is formed by a partial area of one side surface of the support member 30, an area surrounded by a dotted line in fig. 6 is the limit area 32, and there may be no obvious boundary between the limit area 32 and other areas of the side surface. At this time, the area occupied by the notch 31 and the flap 33 may be regarded as a limit area 32. It should be noted that the dashed line in fig. 6 is merely for the convenience of those skilled in the art to understand the limiting region 32, and does not represent that there is a distinct boundary between the limiting region 32 and other regions of the side surface.

Alternatively, the dimension of the slit 31 in the width direction thereof may be small, and even the two opposite inner edges of the slit 31 may be configured to be able to contact each other, so that the initial opening area of the slit 31 is small. The cutout 31 may also have a width such that the cutout 31 has a certain open area in the initial state.

Alternatively, the flap 33 may be configured to be foldable in the insertion direction of the bone screw 40, and may be configured to be foldable in the removal direction of the bone screw 40. Alternatively, the folded piece 33 may be configured to be folded in the insertion direction of the bone screw 40 or in the removal direction of the bone screw 40.

Alternatively, the supporting member 30 and the packing box 10 may be formed in a single structure or a split structure. For example, the support member 30 and the packing box 10 may be formed by integral injection molding.

In the bone screw package according to the embodiment of the present utility model, the supporting member 30 is disposed in the package box 10, and the limiting region 32 of the supporting member 30 is provided with a through incision 31, and the incision 31 divides at least part of the limiting region 32 to form a flap 33. The flap 33 can be folded over relative to the limit area 32 to vary the open area of the incision 31 so that the incision 31 can be inserted into bone screws 40 of different diameters. The folded sheet 33 can also limit the bone screw 40 inserted into the notch 31, so as to avoid frequent friction between the bone screw 40 and the package box 10, further avoid breakage of the package box 10, and be beneficial to keeping the package box 10 intact.

In a specific implementation, the notch 31 may be divided into a single flap 33 in the limiting area 32, or may be divided into a plurality of flaps 33 in the limiting area 32. The slit 31 may be linear, dog-ear, curved, or otherwise regular or irregular. For example, the cut 31 may be V-shaped, C-shaped or U-shaped to form a single flap 33 by cutting at the stop region 32.

As shown in fig. 4 to 6, in some embodiments, the notch 31 is cut in the limit area 32 to form a plurality of flaps 33, the flaps 33 have tips and roots, the roots of the flaps 33 are connected with the inner periphery of the limit area 32, the plurality of flaps 33 are sequentially arranged along the inner periphery of the limit area 32, and the tips of the plurality of flaps 33 are gathered in the middle of the limit area 32. Thus, when the bone screw 40 is inserted into the notch 31, the plurality of folding pieces 33 are folded and split simultaneously, which is beneficial to smooth insertion and release of the bone screw 40, and the plurality of folding pieces 33 limit the bone screw 40 from different angles, which is beneficial to improving the stability of the bone screw 40.

Alternatively, the shape between the plurality of flaps 33 may be the same or different. Alternatively, the notch 31 may be cut into two, three, four, five, or even more flaps 33 in the limiting area 32, and the number of flaps 33 is not limited herein.

In some embodiments, the notch 31 is cross-shaped and cut to form four flaps 33 in the stop region 32, as shown in fig. 6. In this way, the tips of the four folding pieces 33 are at right angles or approximately at right angles, and the folding pieces 33 can maintain proper structural strength, so that the bone screw 40 can be smoothly inserted into the notch 31 or separated from the notch 31, and the bone screw 40 can be stably limited in the notch 31, and the shaking of the bone screw 40 is avoided. Alternatively, the width of the slit 31 in the left-right direction and the up-down direction in fig. 6 may be the same or different.

It will be appreciated that the particular configuration and shape of the cuts 31 and flaps 33 described above is merely exemplary. In particular embodiments, the cut 31 and the flap 33 may take other shapes. For example, the slit 31 may also be in the form of ^“ * ^” Shape of a Chinese character _， This enables six flaps 33 to be formed in the limit region 32 _。

In some embodiments, the stop region 32 is convex toward the direction of extraction of the bone screw 40. As such, the bone screw 40 has a relatively high resistance during insertion and a relatively low resistance during extraction. It is advantageous, for example, that the assembly equipment or assembly workers accurately control the depth of insertion of the bone screw 40 to maintain product consistency. It is also advantageous for the medical practitioner to remove the bone screw 40 during use to enhance the use experience.

Alternatively, the limiting region 32 may be merely protruded in the direction of removing the bone screw 40, or the entire side surface of the limiting region 32 may be protruded in the direction of removing the bone screw 40.

Alternatively, the limiting area 32 may be opposite to the mouth 11 of the package 10, and the limiting area 32 protrudes toward the mouth 11 of the package 10. The stop region 32 may not be opposite to the mouth 11 of the pack 10. For example, the stop region 32 may be opposite and convex toward a side wall of the package 10.

In some embodiments, as shown in fig. 3, the support member 30 is a flat annular band structure, which includes a first band 34 and a second band 35 opposite to each other, and a third band 36 and a fourth band 37 connected between the first band 34 and the second band 35 opposite to each other, respectively, wherein the first band 34 protrudes in the direction of removing the bone screw 40, the second band 35 protrudes in the direction of inserting the bone screw 40, and the limiting area 32 is located on the first band 34. The annular band-shaped structure is relatively easy to deform, and the packing box 10 and the annular band-shaped structure can be pinched from the outside of the packing box 10 when the nail is taken out, so that the bone screw 40 can be pinched stably, and the nail taking tool is favorable for aligning the bone screw 40.

As shown in fig. 7 and 8, in some embodiments, the package 10 has a box opening 11, the first band 34 is opposite to the box opening 11, a first space 16 capable of accommodating a nail cap of the bone screw 40 is formed between the first band 34 and the box opening 11, and a second space 17 capable of accommodating a nail shaft of the bone screw 40 is formed inside the annular band structure. Thus, after the bone screw 40 is placed into the incision 31, the nut is positioned between the first band 34 and the box opening 11, and the shank extends into the annular band structure, which is beneficial to avoiding the contact between the screw thread cutting edge on the shank and the package box 10.

Continuing with fig. 7 and 8, in some embodiments, the package 10 includes a first box section 12 and a second box section 13 sequentially disposed along the insertion direction of the bone screw 40 and having inner cavities communicating with each other, the mouth 11 of the package 10 is disposed at the top end of the first box section 12, and the bottom end of the second box section 13 forms a closed box bottom; the width of the first box section 12 in the first direction is larger than the width of the second box section 13 in the first direction, and the bottom of the supporting part 30 is limited in the second box section 13; the first direction is perpendicular to the insertion direction of the bone screw 40. In this way, the supporting member 30 can be stably limited in the packing box 10 by the second box section 13, and the supporting member 30 and the bone screw 40 are easily taken out integrally by the medical staff due to the relatively large width of the first box section 12 in the first direction.

Alternatively, the width of the support member 30 in the first direction may be smaller than the width of the first cassette section 12 in the first direction. The width of the support member 30 in the first direction may be the same as the width of the second cassette section 13 in the first direction, or may be close to the width of the second cassette section 13 in the first direction. In this way, the stability of the support member 30 can be improved, and a gap is left between the support member 30 and the first box section 12, facilitating removal of the support member 30 and the bone screw 40.

Alternatively, the width of the support member 30 in the second direction is the same as the width of the first cartridge section 12 in the second direction, or is close to the width of the first cartridge section 12 in the second direction. Also, the width of the support member 30 in the second direction is the same as the width of the second cassette section 13 in the second direction, or is close to the width of the second cassette section 13 in the second direction. Wherein the second direction is perpendicular to the insertion direction of the bone screw 40 and the first direction. In this way, not only the second box section 13 can form a limit for the supporting member 30, but also the first box section 12 can form a limit for the supporting member 30 in the second direction, which is beneficial to improving the stability of the supporting member 30.

In some embodiments, the first and second box sections 12, 13 are connected by a transition section 14, the width of the transition section 14 in the first direction being tapered along the insertion direction of the bone screw 40, as shown in fig. 8. In the process of inserting the supporting member 30 into the packaging box 10, the transition section 14 can guide the supporting member 30 to be smoothly inserted into the second box section 13, which is beneficial to improving the assembly efficiency and the yield. Alternatively, the width of the transition section 14 in the second direction may be close to or the same as the first and/or second cassette sections 12, 13. Alternatively, the shape of the bottom of the package 10 may be the same as the shape of the second band 35. In this way, the second belt 35 can be tightly attached to the bottom of the package 10, so as to avoid the support member 30 from moving.

With continued reference to fig. 4 and 5, in some embodiments, the first box section 12 may have a cross-section in the first direction that is oval. Thus, the first box section 12 comprises two opposite cambered side walls and two planar side walls, the two cambered side walls protruding outwards in opposite directions, the two planar side walls being connected between the two opposite cambered side walls. When the two planar side walls are pinched, the first box section 12 is easily deformed and recessed, so that the bone screw 40 can be pinched stably, and a screw extracting tool such as a screwdriver or forceps is aligned with the bone screw 40.

As shown in conjunction with fig. 9 and 10, in some embodiments, the first cassette section 12 may be circular in cross-section in the first direction. As such, the first cartridge segment 12 is generally cylindrical in shape, facilitating the holding of the set bone screw 40 by a medical professional during the stapling process. Alternatively, the cross section of the second box section 13 in the first direction may be circular, and the diameter of the second box section 13 in the first direction is smaller than the diameter of the first box section 12 in the first direction. Thus, the overall size of the packing box 10 is reduced, the overall structure of the packing box 10 is more compact, and the space utilization rate is improved.

In some embodiments, an annular flange 15 is provided on the package 10 around the mouth 11, and the opening closure member 20 is attached to the annular flange 15 and seals the mouth 11. Thus, it is advantageous not only to connect the opening closure member 20 with the packing box 10, but also to maintain the tightness of the packing box 10, and to maintain the aseptic environment within the packing box 10 to some extent. Alternatively, the opening closure member 20 may be, for example, a sealing film, which may be attached to the annular flange 15 by, for example, an adhesive layer or heat sealing. Alternatively, if the mouth 11 is oval, the annular flange 15 may be oval or approximately rectangular, as shown in fig. 1 and 3. If the mouthpiece 11 is circular, the annular flange 15 may be circular or oval, as shown in figures 9 and 10.

The sealing member 20 is not limited to a sealing film, and the sealing member 20 is not limited to being attached to the package 10. The opening closure assembly 20 may also be connected to the package 10 by a hinge, a tab or other connecting structure. For example, the opening closure member 20 may be a cover, and the cover may be disposed at the mouth 11 of the package 10. The cover body can be rotatably connected with the packing box 10, and the cover body can also adopt a split type structure with the packing box 10.

The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
