Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to an instrument box for testing the sharpness of medical scissors. Background Technology

[0002] After surgery, surgical sutures are used for suturing. The sutures are removed after the wound has closed. Suture scissors are commonly used to remove sutures during surgery or in the later stages of recovery.

[0003] Suture scissors need to be kept sharp during use to ensure that they can cut the surgical sutures in one go. Otherwise, insufficient sharpness may tear the wound when cutting the sutures. Therefore, suture scissors need to be tested for sharpness before each use and storage to eliminate scissors with poor sharpness.

[0004] Currently, the sharpness of suture cutters is typically tested by cutting test threads with suture cutters. During testing, a person manually skewers a test thread, and after each test, the thread is skewered again before testing another suture cutter. However, when performing a large number of scissor tests, this method requires repeatedly skewering the test thread, resulting in low efficiency. Utility Model Content

[0005] Based on the above description, this utility model provides an instrument box for testing the sharpness of medical scissors, in order to solve the problem that the suture removal scissor testing method in related technologies requires repeated operation of straightening the test suture, which is inefficient.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] This application provides an instrument box for testing the sharpness of medical scissors, and the technical solution adopted is as follows:

[0008] An instrument box for testing the sharpness of medical scissors includes:

[0009] A box body with an opening, the box body being connected to a lid for closing or opening the opening;

[0010] At least one testing mechanism is disposed within a housing. The testing mechanism includes a test wire and a straightening assembly. The straightening assembly includes multiple clamping structures. Each clamping structure includes two clamping blocks connected to the housing. The two clamping blocks are spaced apart and form a slot between them for the test wire to be inserted. When the test wire is inserted into the slot, it is clamped by the two clamping blocks. The multiple clamping structures are distributed at intervals in a plane parallel to the bottom surface of the housing. The portion of the test wire embedded in the multiple slots and located between adjacent clamping structures is in a straight state.

[0011] Preferably, in each of the clamping structures, a friction plate is provided on the side of the two clamping blocks that are close to each other to increase the friction between them and the test line.

[0012] Preferably, the testing mechanism has multiple components.

[0013] Preferably, the plurality of test facilities are divided into a first group and a second group, and the first group and the second group each include at least two test facilities;

[0014] In the first group of at least two test mechanisms, each test mechanism includes a plurality of clamping structures that are spaced apart along a first straight line direction parallel to the bottom surface of the box, and at least two test mechanisms are spaced apart along a second straight line direction parallel to the bottom surface of the box, wherein the first straight line direction is perpendicular to the second straight line direction.

[0015] In the second group of at least two test mechanisms, each test mechanism includes a plurality of clamping structures that are spaced apart along a second straight line direction, and at least two test mechanisms are spaced apart along a first straight line direction, and each test line in the second group intersects with all the test lines in the first group.

[0016] Preferably, the testing mechanism further includes a wire roller rotatably connected to the housing, and a portion of the test wire is wound around the wire roller.

[0017] Preferably, the lid is provided with a plurality of pressing blocks, each of which corresponds to a plurality of slots. When the lid closes the opening of the box, the plurality of pressing blocks are embedded in the plurality of slots.

[0018] Preferably, the lid is hinged to the box body.

[0019] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0020] 1. This application incorporates at least one testing mechanism within the housing. Within this mechanism, two locking blocks form slots to clamp the test lead. Multiple locking structures at multiple positions along the entire length of the test lead ensure that the portion of the test lead between adjacent locking structures remains taut, even if the test lead has multiple taut segments. During testing, after one wire cutter cuts a taut segment of the test lead, the remaining taut segments remain taut, allowing for direct testing with other wire cutters. Essentially, a complete test lead, clamped in multiple slots, can be used for trial cutting by multiple wire cutters, eliminating the need to re-taut the test lead each time a different wire cutter is tested, thus effectively improving the efficiency of batch testing. Furthermore, after all taut segments of a test lead have been cut, the test lead can be removed from the slots and replaced with a new one for testing; only the test lead needs to be replaced, allowing for reuse and reducing costs.

[0021] 2. This application employs multiple testing mechanisms divided into two groups. In the first group, multiple clamping structures are spaced apart along a first straight line, causing the test lines to extend along that line. The test lines in the first group are also spaced apart along a second straight line. Similarly, in the second group, the test lines extend along the second straight line, and are spaced apart along the first straight line. Each test line in the second group intersects with all test lines in the first group, creating a grid-like structure. Each edge of the grid is formed by taut test lines. Each wire cutter only needs to cut a section of the taut test line during testing. Therefore, this setup allows for more wire cutters to perform trial cuts after a single test line installation, further improving work efficiency. Attached Figure Description

[0031] Reference Figure 1-2As shown, this application embodiment provides an instrument box for testing the sharpness of medical scissors, which includes a box body 1 with an opening and at least one testing mechanism 3 disposed within the box body 1. A box cover 2 for closing or opening the opening is connected to the box body 1. The testing mechanism 3 includes a test line 31 and a straightening assembly. The straightening assembly includes multiple clamping structures. Each clamping structure includes two locking blocks 32 connected to the box body 1. The two locking blocks 32 are spaced apart and form a slot 33 between them for the test line 31 to be inserted. When the test line 31 is inserted into the slot 33, it is clamped by the two locking blocks 32. The multiple clamping structures are distributed at intervals in a plane parallel to the bottom surface of the box body 1. The portion of the test line 31 embedded in the multiple slots 33 and located between adjacent clamping structures is in a straight state.

[0032] Reference Figure 1 As shown, in this embodiment, the box body 1 is rectangular with an opening on one side. The lid 2 is hinged to the box body 1 via a hinge 6, allowing the lid 2 to rotate to open or close the opening. To improve the stability of the lid 2 when the opening is closed, an annular positioning ring 4 is provided on the side of the lid 2 near the box body 1. When the lid 2 rotates to close the opening, the positioning ring 4 is embedded in the opening and contacts the inner wall of the box body 1, thereby limiting the position of the lid 2 and ensuring that the lid 2 stably covers the opening of the box body 1.

[0033] Reference Figure 1-2 As shown, specifically, the spacing between the two locking blocks 32, i.e., the width of the slot 33, is set according to the diameter of the test wire 31, so that the test wire 31 can be embedded in the slot 33 and secured by the two locking blocks 32. To ensure sufficient spacing between the test wire 31 and the bottom of the box 1 for easy wire cutter testing, the locking structure also includes a mounting block 34. The mounting block 34 is connected to the bottom of the box 1, and the locking blocks 32 are connected to the side of the mounting block 34 away from the bottom of the box 1 and are spaced apart from the bottom of the box 1.

[0034] Reference Figure 1-2 As shown, to facilitate the insertion of the test lead 31 into the slot 33, the two locking blocks 32 of the clamping structure are spaced apart in a plane parallel to the bottom surface of the housing 1. When installing the test lead 31, the test lead 31 can be directly inserted into the slot 33 from the opening of the housing 1 towards the bottom of the housing 1.

[0035] Reference Figure 1-2 As shown, furthermore, in each clamping structure, the sides of the two clamping blocks 32 that are close to each other are provided with friction plates 35 to increase the friction between them and the test line 31. By setting the friction plates 35, the clamping effect of the clamping blocks 32 on the test line 31 can be further improved, thereby avoiding the loosening of other taut segments of the test line 31 due to pulling when a section of the test line 31 is cut with a wire cutter.

[0036] Reference Figure 1-2 As shown, furthermore, in order to enable the test box to provide more suture cutters for trial cutting operations at one time, multiple test mechanisms 3 are provided, thereby providing more taut test wires 31 segments. When arranging multiple test mechanisms 3, the multiple test mechanisms 3 are divided into a first group and a second group. The first group and the second group each include at least two test mechanisms 3. In the at least two test mechanisms 3 of the first group, the multiple clamping structures of each test mechanism 3 are spaced apart along a first straight line direction parallel to the bottom surface of the box body 1, and the at least two test mechanisms 3 are spaced apart along a second straight line direction parallel to the bottom surface of the box body 1. The first straight line direction is perpendicular to the second straight line direction. In the at least two test mechanisms 3 of the second group, the multiple clamping structures of each test mechanism 3 are spaced apart along the second straight line direction, and the at least two test mechanisms 3 are spaced apart along the first straight line direction. Moreover, each test wire 31 in the second group intersects with all test wires 31 in the first group.

[0037] Reference Figure 1-2 As shown, specifically, in each test mechanism 3, the distribution direction of the two locking blocks 32 of a locking structure is perpendicular to the distribution direction of multiple locking structures in the test mechanism 3, and the multiple slots 33 are located on a straight line. For example, in a test mechanism 3 of the first group, the two locking blocks 32 of a locking structure are distributed at intervals along the second straight line direction, and when the test line 31 is embedded in the multiple slots 33, the taut segment is parallel to the first straight line direction; while in a test mechanism 3 of the second group, the two locking blocks 32 of a locking structure are distributed at intervals along the first straight line direction, and when the test line 31 is embedded in the multiple slots 33, the taut segment is parallel to the first straight line direction. In this embodiment, the first group and the second group each include four test mechanisms 3 for illustration.

[0038] Through the above arrangement, the multiple test lines 31 in the multiple test mechanisms 3 of the first group and the multiple test lines 31 in the multiple test mechanisms 3 of the second group intersect to form a mesh structure. Each edge of the mesh is formed by a taut test line 31, and each wire cutter only needs to cut a section of the taut test line 31 during testing. Furthermore, the intersecting arrangement of the test lines 31 makes full use of the space within the housing 1. Therefore, after installing the test lines 31 once, a larger number of wire cutters can be used for trial cutting, further improving work efficiency.

[0039] Reference Figure 1As shown, after all the taut segments of the test line 31 are cut, to facilitate the replacement of the test line 31, the test mechanism 3 also includes a wire roller 36 rotatably connected to the box body 1, and part of the test line 31 is wound around the wire roller 36. Specifically, the wire roller 36 is cylindrical with its axis parallel to the bottom surface of the box body 1. In the first group of multiple test mechanisms 3, the axis of the wire roller 36 is parallel to the second straight line direction. In the second group of multiple test mechanisms 3, the axis of the wire roller 36 is parallel to the first straight line direction. The multiple wire rollers 36 in the first group are coaxially sleeved on a rotating shaft 7, while the multiple wire rollers 36 in the second group are coaxially sleeved on another rotating shaft 7. The two ends of the rotating shaft 7 are rotatably connected to the inner wall of the box body 1. Correspondingly, the two rotating shafts 7 are spaced apart in a direction perpendicular to the bottom surface of the box body 1 to avoid mutual interference. The rotating shaft 7 enables the rotatable installation of the wire roller 36 within the housing 1. By rotating the wire roller 36, the test wire 31 can be retracted and extended. After multiple taut segments of the test wire 31 embedded in multiple slots 33 are cut off, the wire roller 36 can be rotated to release the test wire 31 and re-embed the test wire 31 into the multiple slots 33. This allows for reuse and reduces costs.

[0040] Reference Figure 1 As shown, to prevent the test leads 31 embedded in the slots 33 from loosening when the test box is not in use, multiple pressure blocks 5 are provided on the cover 2. Each pressure block 5 corresponds to one of the slots 33. When the cover 2 closes the opening of the box body 1, the pressure blocks 5 are engaged in the slots 33. Furthermore, the pressure blocks 5 are designed such that when the cover 2 closes the opening of the box body 1, they are engaged in the slots 33 and press the test leads 31 firmly onto the mounting blocks 34. This uses the pressure blocks 5 to limit and compress the test leads 31, preventing them from loosening and ensuring they remain taut so that they can be directly cut after the test box is opened.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
