This invention discloses a pre-placed adjustable hernia repair patch and its preparation method, relating to the field of medical device technology. The patch body is a polypropylene woven mesh with a weight of less than 50 g / m². The polypropylene woven mesh has a double-layer gradient structure with different densities on both sides. This pre-placed adjustable hernia repair patch uses a double-layer gradient structure of the same woven mesh. The outer layer has large pores (80-300 μm) to facilitate fibroblast ingrowth and tissue fixation, while the inner layer has small pores (15-80 μm) to form a physical barrier, effectively inhibiting visceral adhesions. It addresses both fixation and anti-adhesion needs. Temporary fixation is achieved through sliding PLGA fixation pins, pre-drilled holes, and elastic rings. The fixation pins are available in various lengths, and the elastic rings enable temporary fixation and position adjustment. Blue marking lines facilitate directional identification, and barium sulfate contrast markers aid in intraoperative positioning and postoperative follow-up.

This invention relates to the field of medical device technology, and discloses a 3D-printed humeral prosthesis that preserves the shoulder joint. The prosthesis includes a prosthesis body, with a proximal end for connecting to the humeral head of the patient's own shoulder joint. The proximal end of the prosthesis body is ball-shaped, and a connection area is provided at the top of the proximal end, with multiple nail-like protrusions. The proximal end of the prosthesis body also has through-holes perpendicular to the connection area. The ball-shaped proximal end of the prosthesis body of this invention, with its connection area, connects to the humeral head of the patient's own shoulder joint, preserving the patient's own shoulder joint, maintaining the patient's natural range of motion and function, reducing damage to surrounding tissues, facilitating more natural movement and recovery of daily activities, and improving postoperative function. The ball-shaped connection has a large contact area, and the nail-like protrusion structure in the connection area of ​​the proximal end of the prosthesis body further increases the contact area, making the connection more stable; this contributes to the initial and long-term stability of the prosthesis implantation.

This invention provides a branch sheath, comprising: a covered cannula, a first connecting tube, a control wire, and a restraint coil. The covered cannula has several drainage holes on its wall to mitigate the impact of blood flow resistance on the delivery and positioning of the branch stent during stent introduction and release, while also reducing complications caused by poor blood flow. The covered cannula is located distal to the first connecting tube; the control wire passes through the first connecting tube, with its distal end located within the covered cannula; the proximal end of the restraint coil is connected to the distal end of the first connecting tube, and the distal end of the restraint coil passes through and extends out of the bare end opening of the branch stent; the portion of the control wire passing through the bare end opening of the restraint coil pulls and fixes the bare end of the branch stent, thereby allowing the branch stent to be pulled back into the branch vessel at any time after it has detached from its predetermined position during the procedure, preventing displacement of the branch stent due to the pull of the main stent, and achieving precise control of the release position.
