Described herein are hydrogel-coated surgical meshes and their use in hernia repair, reconstructive surgery, and other surgical procedures. In one aspect, the hydrogel-coated meshes comprise at least one antibiotic or antimicrobial agent for the treatment of hernia repair surgery. In one aspect, the hydrogel coated meshes provide localized, sustained antimicrobial activity for the treatment of surgical site infections. In one aspect, the hydrogel coated meshes provide localized, sustained prophylactic antimicrobial activity for the prevention of surgical site infections. In another aspect, the hydrogel coating may optionally include one or more additional therapeutic components, such as anti-inflammatory compounds or growth factors, to facilitate and enhance recovery following hernia repair, reconstructive procedures, or other surgeries.

The present embodiment relates generally to methods of performing surgical technique maxillary sinus floor augmentation with a lateral approach using a pre-portioned and ready pre-packaged bone graft composition in gelatin bags and method of producing gelatin bags. In addition the present inventions can be widely used in other medical fields such as dentistry, orthopedic surgery, spine surgery, plastic and reconstruction surgery, sport medicine, trauma surgery, phinoplasty surgery and veterinary.

A bone fixation plate may include a first end and a second end opposite and spaced apart from the first end along a longitudinal axis. The bone fixation plate further includes a first surface extending from the first end to the second end and a second surface opposite from the first surface. The bone fixation plate further includes a network of interstices disposed between the first surface and the second surface. The plurality of interstices is provided based on a stiffness matching system and method with respect to an underlying bone or a virtual surgical model thereof. The bone fixation plate further includes a plurality of screw holes defined by and extending through the bone fixation plate from the first surface to the second surface.

The invention belongs to the technical field of ear shaping and reconstruction surgery, particularly relates to an autologous costal cartilage ear stent bonding and bearing device, and aims to solve the problem that in order to simulate a thin-layer structure of a natural auricle, cartilage subunits are generally engraved to be extremely thin, so that the cartilage subunits are prone to plastic deformation in the bonding process. The device comprises a bearing mechanism; the bearing mechanism comprises a bearing disc and bearing liquid filled in the bearing disc; the bearing disc is configured to contain cartilage subunits to be bonded; and the bearing liquid is medical liquid with biocompatibility. When the bonding and bearing device for the autologous costal cartilage ear stent is used, the bearing liquid applies upward buoyancy to the cartilage subunit in the bearing disc, so that the cartilage subunit suspends in the bearing liquid for bonding operation, and then the mechanical clamping force required for fixing the cartilage subunit in the bonding process is reduced; and the compression effect of gravity on the cartilage subunit is reduced.

This invention discloses a system, device, and application for designing osteotomy angles in osteotomy correction surgery for kyphosis. The system includes an input module, a data processing module, and an output module. It calculates the osteotomy angle based on spinal data obtained from full-length lateral images of the spine. The spinal data includes data measured from the images and calculated data. Combining clinical experience, after providing the proximal osteotomy angle, the osteotomy angle at the distal osteotomy apex can be directly calculated. The design system of this invention is simple to operate and easy to understand, and is of great significance for the treatment of patients with kyphosis.

Disclosed are miniaturized, wearable microneedle biosensor devices, systems, and methods for measuring intradermal concentrations of various metabolites (including but not limited to lactate, pyruvate, and / or glucose) in order to directly assess the viability of living tissue (e.g., human or other mammalian soft tissue). In a variety of implementations, for example, the disclosed microneedle biosensor devices are self-contained in terms of power source, sample acquisition, measurement, and data transmission capabilities, e.g., allowing it to function autonomously once placed. In some implementations, for example, the disclosed microneedle biosensor devices can assess the viability of soft tissue (e.g., skin with or without fat, fascia, or muscle) during and after reconstructive surgery in which soft tissue is repositioned, rotated, or transferred to another site in the body (including but not limited to both microvascular free tissue transfer and regional pedicled flaps).

Three-dimensional view reconstruction of a surgical scene using an image is provided. A system can identify a frame that captures a single view angle of a scene in a medical procedure performed with a robotic medical system. The system can generate, using one or more models trained with machine learning, one or more masks that segment an anatomical structure in the frame, label the anatomical structure in the frame, and indicate a depth value for each pixel in the frame. The system can construct a 3D mesh based on the one or more masks. The system can generate a video corresponding to a plurality of view angles of the frame using the one or models and the 3D mesh and the labels of the anatomical structures from the one or more masks.

A graft compression system for compressing soft tissue grafts used in connection with reconstructive surgery. The graft compression system includes an upper press body and lower press body, pivotally couple to one another, each having inner sides having a plurality of parallel semi-circular shaped channels formed thereon. The plurality of parallel semi-circular shaped channels have sequentially decreasing channel widths. The upper press body and said lower press body of the graft compression system are configured to pivot about a pivot pin such that the inner sides abut one another, and such that the two sets of semi-circular shaped channels are substantially aligned with one another so as to receive a graft for compression. A screw press barrel is attached to the lower press body, on a side opposite the pivot pin, and is configured to compress the upper press body and lower press body.
