[0002] In modern medical technology, needle puncture force testing is a crucial step in evaluating the performance of medical devices. This is especially true for curved needles (such as 3 / 8 arc and 1 / 2 arc needles), whose puncture performance directly impacts the safety and effectiveness of clinical procedures.

[0003] During manual installation, differences in operator skill level and experience can lead to inconsistent needle positions, making it impossible for the needle to maintain a strictly vertical insertion angle. Furthermore, this manual installation method can easily cause errors between the needle's axis and the servo motor's axis in actual operation, thus affecting the needle's vertical puncture capability. Secondly, this lack of precision not only affects the accuracy of test results but also leads to inaccurate measurement of frictional forces during dynamic puncture, further impacting the assessment of puncture force.

[0052] Example 1

[0053] An illustrative embodiment of this utility model, such as Figure 1 As shown, an auxiliary positioning structure 100 for holding a suture needle includes a positioning base 110, an engagement notch 120, and at least one positioning step 130. The engagement notch 120 is formed in the positioning base 110 and is used to engage with the clamping end of the suture needle clamping component 300 to assemble the positioning base 110 and the clamping component 300. The positioning step 130 is disposed on the positioning base 110 and is coaxially arranged with the positioning base 110, used to position the suture needle to calibrate its axis.

[0054] Specifically, the positioning base 110 includes a sector-shaped plate and two extension plates. The two extension plates are integrally formed with the sector-shaped plate and are symmetrically arranged on the sector-shaped plate. The extension plates allow the positioning base 110 to engage with the clamping end of the clamping component 300. After the suture needle is assembled, it can be directly removed from the clamping end of the clamping component 300.

[0055] In some embodiments, the positioning base 110 includes, but is not limited to, a stainless steel fan-shaped base.

[0056] Specifically, the engagement notch 120 is formed on the positioning base 110, and the engagement notch 120 is a one-sixth fan-shaped area. This structure facilitates the fitting of the positioning base 110 with the clamping end of the clamping component 300.

[0057] It should be noted that the structure of the engaging notch 120 is adapted to the structure of the clamping end of the clamping component 300; it should be understood that the structure of the engaging notch 120 is not limited to a fan-shaped structure, but can also be a trapezoidal structure, etc., that is, it can be adapted to the structure of the clamping end of the clamping component 300.

[0058] Specifically, the positioning step 130 has a fan-shaped structure. The positioning step 130 can be set on the positioning base 110 by means of welding, riveting, magnetism or integral molding, and the axis of the positioning step 130 is coaxial with the positioning base 110.

[0059] In some embodiments, the positioning step 130 includes, but is not limited to, a stainless steel sector plate.

[0060] It should be noted that the outer diameter of the positioning step 130 is 0.5mm to 40mm; it should be understood that the outer diameter of the positioning step 130 can be 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, etc., that is, the outer diameter of the positioning step 130 can be selected according to the size of the suture needle to be tested.

[0061] The usage method of this embodiment is as follows:

[0062] In actual use, an auxiliary positioning structure 100 of appropriate size is selected according to the size of the suture needle to be tested, and the positioning base 110 is engaged with the clamping end of the clamping component 300.

[0063] Subsequently, the needle body of the suture needle is fully fitted with the arc side of the positioning step 130, thereby calibrating the axis of the suture needle so that the axis of the suture needle and the axis of the output shaft of the drive component 200 are on the same straight line.

[0064] Finally, the calibrated suture needle is clamped by the clamping component 300 to facilitate subsequent suture needle puncture force attenuation test experiments.

[0065] The advantage of this embodiment is that, through the design of the positioning base 110 and the positioning step 130, the structure can effectively and accurately position the suture needle; in addition, the coaxial arrangement of the positioning step 130 ensures that the axis of the suture needle is aligned with the axis of the output shaft of the drive component 200, thereby ensuring that the suture needle is strictly perpendicular to the simulated medium during the puncture process, which can improve the accuracy of the test results.

[0066] Example 2

[0067] This embodiment is a modified embodiment of embodiment 1.

[0068] like Figure 2 As shown, when there are multiple positioning steps 130, the multiple positioning steps 130 are stacked sequentially along the axial direction of the positioning base 110; wherein, the diameter of the multiple positioning steps 130 decreases sequentially along the axial direction of the positioning base 110, and the difference in diameter between two adjacent positioning steps 130 is 1mm to 3mm.

[0069] In this embodiment, multiple positioning steps 130 are integrally formed on the positioning base 110, and the number of positioning steps 130 is 10. It should be noted that the number of positioning steps 130 can also be 4, 6, 8, 12, 14, etc., that is, the number of positioning steps 130 can be set according to the number of different specifications of suture needles in actual testing, and no further restrictions are imposed here.

[0070] In this embodiment, the difference in diameter between two adjacent positioning steps 130 is 2mm. It should be noted that the difference in diameter between two adjacent positioning steps 130 can also be 1mm, 3mm, etc., that is, the difference in diameter between two adjacent positioning steps 130 can be set according to actual needs, and no further restrictions are imposed here.

[0071] In this embodiment, the diameters of the 10 positioning steps 130 along the axial direction of the positioning base 110 from near the positioning base 110 to far away from the positioning base 110 are 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, and 30mm, respectively.

[0072] The usage method of this embodiment is as follows:

[0073] In actual use, the positioning base 110 is engaged with the clamping end of the clamping component 300;

[0074] Subsequently, according to the specifications of the suture needle, the needle body of the suture needle is fully fitted with the arc side of the corresponding positioning step 130, thereby calibrating the axis of the suture needle so that the axis of the suture needle and the axis of the output shaft of the drive component 200 are on the same straight line.

[0075] Finally, the calibrated suture needle is clamped by the clamping component 300 to facilitate subsequent suture needle puncture force attenuation test experiments.

[0076] The advantage of this embodiment is that by setting multiple positioning steps 130, users can select the appropriate positioning step 130 according to different specifications of suture needles. This flexibility makes the structure applicable to a wider range of suture needle types and meets different experimental needs. In addition, the design of multiple positioning steps 130 makes the positioning of the suture needle more precise. The diameter difference between two adjacent positioning steps 130 can be adjusted according to actual needs, providing the possibility of step-by-step calibration and helping to achieve higher positioning accuracy.

[0083] Specifically, the positioning groove 150 is designed as an arc groove, and the axis of the positioning groove 150 is the same straight line as the axis of the positioning base 110.

[0085] It should be noted that the depth and width of the positioning groove 150 can also be 0.5mm, 2mm, etc., that is, the depth and width of the positioning groove 150 can be set according to actual needs, and no further restrictions are imposed here.

[0086] like Figure 3 As shown, the positioning step 130 also includes a positioning protrusion 160. The positioning protrusion 160 is formed at the bottom of the positioning step 130 and is interlocked with the positioning groove 150 to position the positioning step 130 on the positioning base 110.

[0087] Specifically, the positioning protrusion 160 is provided with an arc-shaped structure, and the positioning protrusion 160 is provided on the positioning step 130 by means of welding, riveting or integral molding. The axis of the positioning protrusion 160 and the axis of the positioning step 130 are the same straight line, that is, the positioning protrusion 160 can be embedded in the positioning groove 150 to realize the positioning of the positioning step 130 on the positioning base 110, and realize that the axes of the positioning step 130 and the positioning base 110 are the same straight line.

[0089] It should be noted that the height and width of the positioning protrusion 160 are compatible with the depth and width of the positioning groove 150; it should be understood that the dimensional parameters such as the height and width of the positioning protrusion 160 are compatible with the dimensional parameters such as the depth and width of the positioning groove 150.

The connector 140 can connect the positioning step 130 and the positioning base 110 on its own.

[0092] Subsequently, the positioning base 110 is engaged with the clamping end of the clamping component 300;

[0093] Next, the needle body of the suture needle is fully fitted with the arc side of the positioning step 130, thereby calibrating the axis of the suture needle so that the axis of the suture needle and the axis of the output shaft of the drive component 200 are on the same straight line.

[0094] Finally, the calibrated suture needle is clamped by the clamping component 300 to facilitate subsequent suture needle puncture force attenuation test experiments.

[0095] The advantage of this embodiment is that the interlocking of the positioning protrusion 160 and the positioning groove 150 ensures that the axis of the suture needle and the driving component 200 are aligned. The operation is simple and easy, highly adaptable, and can be adjusted according to different specifications of suture needles. This enhances the stability and durability of the structure, reduces human error, and thus improves the reliability and efficiency of the overall experiment.
