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.

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.

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 device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress / strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient. A method of 3D printing nitinol to create a patient-specific device to facilitate the establishment of a normal stress-strain trajectory in grafted bone.
