Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a tooling for testing the cutting quality of metal stents. Background Technology

[0002] Intracranial thrombectomy stenting is primarily used to treat cerebrovascular diseases, especially common conditions like cerebral infarction. Cerebral infarction is caused by cerebral ischemia due to blockage of blood vessels in the brain. The procedure is performed under general anesthesia. A small incision (no more than 2 cm) is made in the skin of the patient's groin, and a very thin catheter is inserted into the blood vessel. A guidewire and catheter are guided through the catheter to the blood vessel in the brain until the thrombus is reached. Based on the location of the thrombus and the diameter of the blood vessel, an appropriate thrombectomy stent is selected, advanced through the catheter to the thrombus site, and released, allowing the stent to open and contact the thrombus. After the stent has made full contact with the thrombus, the stent and catheter are slowly withdrawn, removing the thrombus and stent together. Post-operatively, angiography is performed to ensure the blood vessel is patent and there is no re-occlusion or bleeding. The catheter and sheath are removed, and the puncture site is sealed with a pressure bandage. The patient is then safely transferred to the intensive care unit for post-operative observation.

[0003] During the quality inspection of intracranial thrombectomy stents, the stent body is cut from a nickel-titanium tube with a diameter of less than 0.5 mm. Direct clamping and rotation with tweezers may cause bending, microcracks or surface damage, which in turn affects its self-expansion performance, mechanical strength and antithrombotic properties.

[0023] like Figure 1 , 2 As shown in Figure 3, a sliding hole 261 is provided below the transmission plate 26, and a limiting block 262 is fixedly installed inside the sliding hole 261. An adjustment hole 281 is provided below the adjustment plate 28, and a fixing block 282 is fixedly installed inside the adjustment hole 281.

[0024] like Figure 2 , 3 As shown in Figure 4, the adjusting rod 31 in the adjusting member 3 is located inside the sliding hole 261. An adjusting handle 32 is installed at the right end of the adjusting rod 31, and a transmission gear 33 is fixedly installed on the side of the right end of the adjusting rod 31.

[0029] In operation, this invention involves placing the support between two cylinders 27 and rotating the adjusting handle 32 to rotate the adjusting rod 31. The spiral groove 311 and spiral recess 312 on the adjusting rod 31, under the action of the limiting block 262 at the lower end of the transmission plate 26, can precisely adjust the distance between the transmission plates 26. The transmission plates 26 are connected via the connecting plate 24, enabling synchronous adjustment of the distance between the two cylinders 27, thus accommodating supports of different diameters.

[0030] After the spacing adjustment is completed, rotating the handle 22 will drive the rotating cylinder 21 to rotate.

The rotating cylinder 27 allows the bracket to be rotated 360° in all directions, which is convenient for inspection without blind spots and effectively avoids the problem of scratches or deformation on the surface of the bracket that may be caused by traditional tweezers.

[0031] After the examination, simply increasing the spacing between the cylinders 27 will allow the stent to slide down naturally. The specially designed base 1 is equipped with an acrylic transparent plate; when the spacing between the cylinders 27 is too far, the stent can safely land on the transparent plate, facilitating non-invasive placement and removal by medical personnel using tools such as tweezers. This structure ensures both ease of operation and the safety of the stent throughout the examination.
