Problems solved by technology
[0004] (1) The surgical instruments are complex and the inventory process takes a long time
[0005] (2) Since the instruments are dynamic and practical during the operation, it is not easy to find which instrument is not included
[0006] (3) There are many types of orthopedic instruments, and it takes time to search for them, resulting in potential safety hazards when the patient is waiting for anesthesia
[0007] (4) Due to the large number of counts (at least 4 times), it is easy to appear confusion and unclear numbers
[0009] The stacking of surgical instruments has problems such as occlusion, overlapping, and partial missing, which are difficult to solve technically

Embodiment
[0068] During the automatic data matching of the device image acquired by the intelligent scanner of the present invention, two-dimensional reconstruction is performed using the scanned image sequence;
[0069] Select adjacent images to generate similar features based on neighborhood-based block matching, and determine the neighborhood step size n, that is, each image will calculate similar features with the two left and right images;
[0070] After determining the step size n of adjacent image matching, traverse the entire image sequence, take each image as the reference image, and perform neighborhood-based block matching with the next n frames of images; in the original image, along the row and column directions, each Take a point every other pixel as a feature point that needs to be matched for feature calculation based on block matching;
[0071] After determining the sampling rate K, for each pair of images (P 1 , P 2 ) is the P that needs to be calculated 1 The match...

The invention belongs to the technical field of medical instruments and discloses an intelligent scanner for checking surgical instruments and a control method of the intelligent scanner. The instruments are scanned in real time through the intelligent scanner and uploaded to a checking system, and the checking system is automatically subjected to data matching with instrument images obtained by the intelligent scanner according to the number and the type of the instruments in an instrument database and a map database; meanwhile, missing and the number of all the instruments are pre-warned andpromoted through an alarm promoter; and whether the number and the type of the instruments of the instrument database are intact or not is displayed by a display screen. Missing and the number of allthe instruments can be pre-warned and promoted; the checking system confirms the controllability of the number of scanned objects, the specification and the number of the missing objects are provided, and nurses or doctors find the objects and counter points according to guidance; and the checking speed is increased, checking accuracy is improved, the time of checking the instruments under narcotizing of surgery patients is saved, thus the time cost of medical personnel is saved, and unnecessary personnel waste is reduced.
Description
technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a scanner and a control method for intelligently counting surgical instruments. Background technique [0002] At present, the existing counting method and verification of surgical instruments are manual counting and verification. After the operation, the nurse needs to count the instruments repeatedly, sing at least twice, and also need to record while repeating to ensure that all the instruments are complete. Now this counting method requires at least 30-60 minutes for the nurse to count, and the counting is repeated to confirm that it is correct. This way greatly wastes the time of nurses and increases the workload of nurses, causing unnecessary waste of personnel. And if the personnel make mistakes during the counting process, the number of instruments will be inconsistent, which is very likely to affect the lack of instruments used in the next operat...
