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 interbody fusion device technology, specifically a 3D-printed porous interbody fusion device, comprising a fusion device body, a first filling hole penetrating through the middle of the fusion device body, and a plurality of internal reinforcing ribs evenly distributed circumferentially on the inner wall of the first filling hole. Based on the biomimetic mechanical design concept of the biomedical engineering industry, this interbody fusion device can break through the limitations of traditional fixed-width fusion devices, and can accurately match the anatomical width of the intervertebral space of different patients without the need for manual cutting and modification during surgery. It can fully adapt to the individualized needs of various heights, weights and disease segments, and fundamentally avoid the risks of endplate damage, infection and anchoring structure damage caused by cutting. After implantation, the self-locking component can achieve immediate rigid locking, completely blocking the reverse rebound path of the adjustment block. Combined with the multi-occlusal tooth structure, it forms a stable mechanical anchor, eliminating postoperative micromovement, displacement and slippage problems, and greatly improving the overall stability of the fusion device in the early stage of implantation.

This invention relates to an anastomosis device for gingival surgical incisions, comprising a main body structure, a gripping structure, several staple structures, a staple delivery structure, two power structures, and a staple separation structure. Its advantages lie in that, by rotating the gripping structure to the main body structure, the gripping structure drives the two power structures to move along the length of the main body structure, pressing the staple separation structure towards the staple structure, thus separating the staples; simultaneously, the power structures push the separated staple structures, causing them to move along the staple delivery structure. The staple delivery structure clamps both sides of the surgical incision and deforms the staple structures, separating them from the staple delivery structure, thereby compressing both sides of the surgical incision and achieving anastomosis. This eliminates the need for staples to puncture the gums, reducing trauma, and is simple and convenient to operate. It allows for rapid suturing of surgical incisions, and the protruding staple delivery structure allows for anastomosis of gums deep within the oral cavity.

This invention discloses a photocurable fixation auxiliary device for ingrown toenail correction, comprising an ingrown toenail body and a flexible rectangular frame. The correction mechanism includes an Ω-shaped correction wire, with hooks fixed to both ends of the Ω-shaped correction wire to hook onto the side edge of the ingrown toenail body. Each hook has an anti-slip strip fixed to its inner front surface. A curing pen is provided on the top of the flexible rectangular frame. This invention, through the cooperation of the Ω-shaped correction wire, auxiliary wire, and hooks, can form a central bridging fulcrum and bilateral symmetrical ring arms on the surface of the ingrown toenail body, thereby achieving three-dimensional correction force on the ingrown toenail body in an upward, outward, and forward direction. This addresses the growth trajectory of the ingrown toenail body from the root cause, with minimal trauma and a low recurrence rate. Simultaneously, through the cooperation of the curing pen, conical shell, and flexible rectangular frame, the photocurable resin inside the flexible rectangular frame can be photocured, ensuring that the entire ingrown toenail correction device remains securely fixed after installation.

This invention discloses an electrode implantation tool. The distal end of the electrode is provided with a fixing component. The implantation tool includes an outer sheath and an inner sheath. The inner sheath includes an inner sheath tube and a first handle. The outer sheath includes an outer sheath tube and a second handle. The inner sheath tube can be inserted into the outer sheath tube. The first handle can be locked within the second handle. The second handle has at least a first locking position and a second locking position in the axial direction, allowing the first handle to move from the first locking position to the second locking position. The inner diameter of the inner sheath tube is smaller than the outer diameter of the fixing component, and the inner diameter of the outer sheath tube is larger than the outer diameter of the fixing component. Other parts of the electrode, excluding the fixing component, can be inserted into the inner sheath tube. This invention allows for a single puncture of the electrode and implantation tool near the target nerve tissue. After successful testing, the electrode is directly released and fixed, ensuring consistency between the test point and the implantation point.

The utility model relates to shearing force technical field discloses a kind of adjustable synovial fold shearing force, including handle one, the one end of handle one is fixedly connected with turning plate, the inside rotation of turning plate is connected with handle two, reset component is provided between handle one and handle two, the reset component is used to drive handle two reset, the one end of turning plate is rotatably connected with extension rod, the one end of extension rod is rotatably connected with hook knife and segmentation knife.The utility model in which, first through small diameter, pipe-like shearing force with scale design, allow to enter inside through very small incision, realize minimally invasive treatment, greatly reduce the trauma of operation, while not only reduce the complexity of doctor operation, can also be flexibly operated in narrow operation space, facilitate hooking synovial fold and cutting in operation, in addition, the shearing force simple structure is lower in cost, effectively reduce medical cost.

This invention discloses a biomarker for detecting placenta accreta, namely the MI R323B gene. Reduced expression of MI R323B in subject samples is an indicator of placenta accreta. Furthermore, the application of MI R323B as a diagnostic biomarker for placenta accreta in the preparation of reagents for diagnosing placenta accreta is disclosed. Results show that the MI R323B gene expression level is downregulated in PAS patients, with high diagnostic accuracy. MI R323B plays an important role in the diagnosis and treatment of placenta accreta and can be used to prepare drugs for treating placenta accreta or related diseases.
