The limiting component includes a connecting frame and a connecting arc plate. An outer wall of the connecting frame is provided with a fixed pressing plate, and a bottom of the fixed pressing plate is provided with a positioning clamping plate. A plurality of positioning slots are provided in the connecting frame and the connecting shaft. The positioning clamping plate is fixedly sleeved in the positioning slots.

The application discloses a laryngeal external fixing device for laryngeal microsurgery, which comprises a fixing disc and at least one bandage arranged at two ends of the fixing disc; the fixing disc is arc-shaped and is provided with four screws; the head end of the screw is located at one side of the fixing disc; the tail end of the screw is connected with a pressing sheet and is located at the other side of the fixing disc; the outer edge surface of the pressing sheet is wrapped with a flexible pad; the opposite positions of the four screws are respectively corresponding to the incisure, the left lamina and the right lamina of the thyroid cartilage and the annular cartilage; the laryngeal external fixing device can press the thyroid cartilage and the annular cartilage and saves manpower.

The application relates to the field of medical devices, in particular to an external fixing device for clavicle fracture, which comprises a clavicle belt, a pressure pad is arranged on the clavicle belt, a covering groove is arranged on the side close to the clavicle of the pressure pad, and an isobaric fitting assembly is symmetrically arranged on the two sides of the covering groove and used for isobaric force fitting with the clavicle based on the clavicle shape. The application can be self-adaptively adjusted and fitted according to the individualized clavicle shape of a patient, so that personalized fixation is realized, and the fracture healing is better promoted.

To digitally determine the actual position and pose of a known collection of objects in a projected three-dimensional space lying above a digital two-dimensional radiographic space.SOLUTION: The method comprises digitally inputting a first digital radiographic image depicting the known collection of objects in the projected three-dimensional space lying above the two-dimensional radiographic space. The method also comprises utilizing depictions of the known collection of objects in the two-dimensional radiographic space in the first digital radiographic image to determine the actual position and pose of the known collection of objects in the projected three-dimensional space lying above the two-dimensional radiographic space.SELECTED DRAWING: Figure 3

This invention discloses a method for quickly fabricating clamps to repair leaks in sewage pipelines using pipe fittings. The method includes: directly using an existing pipe of the same diameter as the project site, splitting the pipe at its center into an upper and lower half, and adjusting it to form two semi-circular external fixing devices; welding iron lugs to both sides of the external fixing devices; pre-drilling holes on each iron lug for bolts; during installation, using the upper and lower half as external fixators, completely encasing the interior of the upper and lower half with sealing pads, and connecting the upper and lower half as external fixing components using bolts; the bolts pass through the pre-drilled holes on the two iron lugs of the upper and lower half, and the stress from the continuous tightening of the bolts gradually tightens the internal sealing pads, thus completing the leak-sealing work through compression. The purpose of this invention is to quickly resolve pipeline leak problems when there are multiple leaks in sewage transport pipelines, and when funds and time are limited.
