Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a polymer stent development marking mounting platform. Background Art

[0002] Polymer stents are made of biodegradable materials and, after implantation at the site of a lesion, provide short-term support for blood vessels. After treatment, the stent degrades within the human body into products that can be absorbed and metabolized, eventually disappearing. However, these biodegradable stents are typically made from high-molecular-weight polymers, which are not visible under X-rays. This can complicate positioning during implantation, post-implantation inspections, and subsequent follow-up.

[0003] The main solution to the existing problem of developing polymer stents is to embed a developing marker into the stent. Currently, during the press-fitting process for developing markers on polymer stents, the developing marker is placed on the polymer stent using vacuum suction, then manually pressed to embed the developing marker into the polymer stent.

[0004] The existing solutions have the following disadvantages in terms of pressing the development marker:

[0005] (1) The development marker is a tiny spherical metal. If it shakes or tilts slightly during manual pressing, it will cause the marker to deviate and damage the bracket, or the surface of the pressed marker will be uneven, resulting in an increased failure rate.

[0006] (2) When manually pressing the imaging marker, the accuracy of the pressing force cannot be controlled. If the pressing force is too small, the imaging marker will protrude too high relative to the surface of the stent and easily fall off; if the pressing force is too large, the stent will be pressed, causing damage to the stent.

[0007] (3) When the original developing marker is pressed manually, the protrusion height of the developing marker relative to the bracket cannot be accurately controlled. Summary of the Invention

[0008] To solve the above problems, the present invention discloses a polymer stent developing mark mounting platform with a simple structure and easy operation. When pressing the developing marker, the polymer stent will not be damaged, thereby reducing production costs and improving product quality.

[0009] To achieve the above object, the technical solution of the present invention is as follows:

[0010] A polymer bracket development mark mounting platform, comprising a base plate, a supporting platform, a lifting platform, a pressing platform and a bracket shaft; the supporting platform is mounted on the base plate, a square groove is provided in the middle of the supporting platform, grooves are provided on both sides of the square groove, and the bracket shaft is arranged in the groove, the lifting platform comprises a pulley, a spring steel wire rope, a vertical plate and a sliding rail, the pulley is fixedly mounted above the sliding rail, and the vertical plate is vertically mounted on the base plate; the sliding rail is arranged on the front end surface of the vertical plate, the pressing platform comprises a spring handle, a sliding block and a working block, the spring steel wire rope is connected to the sliding block through the pulley, the sliding block moves on the sliding rail, the spring handle and the working block are mounted on the outside of the sliding block, and a limit block and a pressure block are provided below the working block, and the height of the lower plane of the limit block is lower than the height of the lower plane of the pressure block.

[0011] As an improvement of the present invention, a rib is provided at the rear end of the vertical plate.

[0012] As an improvement of the present invention, the support platform is mounted on the base plate by bolts.

[0013] As an improvement of the present invention, the working block is mounted on the outside of the sliding block by means of bolts.

[0014] As an improvement of the present invention, the support platform and the working block surface are provided with markings.

[0015] The beneficial effects of the present invention are:

[0016] The present invention has a simple structure and is easy to operate. Due to the height difference between the limiting block and the pressing block, the polymer bracket will not be damaged when the developing marker is pressed, thereby reducing production costs, improving the accuracy of pressing the developing marker, and improving the production qualification rate.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] As shown in the figure, a polymer bracket development mark mounting platform described in the present invention includes a base plate 5, a supporting platform 4, a lifting platform 1, a pressing platform 2 and a bracket shaft 3; the supporting platform 4 is installed on the base plate 5, a square groove 16 is provided in the middle of the supporting platform 4, and grooves 17 are provided on both sides of the square groove 16, and the bracket shaft 3 is arranged in the groove 17, the lifting platform 1 includes a pulley 15, a spring steel wire rope 13, a vertical plate 10 and a sliding rail 6, the pulley 15 is fixedly installed above the sliding rail 6, and the vertical plate 10 is vertically installed on the base plate 5; the sliding rail is arranged on the front end surface of the vertical plate 10, the pressing platform 2 includes a spring handle 8, a sliding block 22 and a working block 7, the spring steel wire rope 13 is connected to the sliding block 22 through the pulley 15, and the sliding block 22 moves on the sliding rail 6, the spring handle 8 and the working block 7 are installed on the outside of the sliding block 22, and a limit block 9 and a pressure block 11 are provided below the working block 7, and the height of the lower plane of the limit block 9 is lower than the height of the lower plane of the pressure block 11.

[0024] The polymer stent development mark mounting station of the present invention has a working block 7 above the support platform 4. When working, the stent 20 with the development mark is nested on the stent shaft 3. Figure 3 As shown, the bracket shaft 3 is placed in the groove 17 of the support platform 4; the spring handle 8 is pressed to move the working block 7 downward along the sliding track 6, and the lower plane of the limit block 9 contacts the bottom surface 12 of the groove. At this time, the lower plane of the pressure block 11 presses the development mark. The present invention uses the height difference between the limit block 9 and the pressure block 11 (with the bottom surface 12 of the groove as the base surface) to avoid damaging the polymer bracket when pressing the development marker, thereby reducing production costs, improving the accuracy of pressing the development marker, and improving the production qualification rate.
