The described embodiments are only some, but not all embodiments of the invention. Under the prerequisite that does not deviate from the design concept of the utility model, the ordinary person in the art should fall into the protection scope of the utility model to the various changes and improvements that the technical scheme of the utility model made.
Example (b):
as shown in fig. 1-5, an ultrasound fusion navigation assisted registration device includes a fixed base 1, in this embodiment, the fixed base 1 is a regular rectangular body, a protrusion 2 is integrally provided in the middle of the top surface of the fixed base 1, and a registration slot 21 matched with the shape of an ultrasound probe is provided in the middle of the protrusion 2; fixed baseplate 1 and protruding portion 2 all follow the axis symmetry, counterpoint groove 21 set up along the axis of protruding portion 2. The alignment groove 21 is a recessed groove with smooth edge, and its recessed shape is matched with the front end of the ultrasonic probe used for examination. In the operation process, the front end of the probe is completely attached to the groove of the alignment groove 21, so that the alignment accuracy is ensured. In the embodiment, the fixing base 1, the protrusion 2 and the alignment groove 21 are made of medical plastic materials; the convenience and the safety of use are ensured.
A mark line 4 is arranged on the outer surfaces of the protruding part 2 and the fixed base 1 at the periphery of the alignment groove 21, and the mark line 4 is a central axis of the fixed base 1 and the protruding part 2; on the ultrasonic probe, a marking line 4 matching the marking line is also provided. The marking line 4 can be used for assisting the alignment of the ultrasonic probe.
An adhesive part 5 for fixing the auxiliary registration device to the body surface of the patient is fixedly connected to the bottom surface of the fixing base 1. The bottom surfaces of the fixed base 1 and the pasting part 5 are regular planes; the sticking part 5 can be conveniently stuck to the surface of the body to be checked, and the positioning stability in the checking process is ensured.
The ultrasonic fusion navigation auxiliary registration device can effectively improve the speed, the precision and the automation degree of registration and realize the stability and the repeatability of registration. The using method comprises the following steps:
(1) preparing before the examination of the patient, and adhering an adhering part 5 at the bottom of a fixed base 1 on the auxiliary registering device on the outer skin of the part of the examined person needing to be examined; performing early CT or MRI examination along with the subject;
(2) inserting the ultrasonic probe used for inspection into the groove of the alignment groove 21, and completely attaching the front part of the ultrasonic probe used for inspection to the groove of the alignment groove 21; the marking lines 4 are required to be in one-to-one correspondence with the median lines of the ultrasonic probes used for examination;
(3) imaging on a second image of the examination such as the prior CT or MRI and the like, and determining the plane position of the registration mark 3;
(4) and (4) on the fusion registration operation interface, determining a single key to finish registration.
By using the technical scheme, the ultrasonic fusion registration navigation-assisted registration is realized, and in the registration process, the ultrasonic image and the second image do not need to be concerned in the whole process, and only the probe needs to be correctly placed and the single key is used for confirming the alignment. The method has the advantages of simple operation, high alignment precision and low requirement on the experience of an operator, and the whole process takes 20-40 seconds, thereby greatly shortening the registration time.
The external registration method is an image registration method which is universal for various fusion navigation technologies, and a marker positioning patch is pasted on the skin surface of an examination part, and the marker positioning patch has the common characteristic that the image can be displayed on a second image such as CT or MRI. After a patient carries the marker positioning stickers to carry out CT/MRI examination, the images are guided into an ultrasonic navigation system to reconstruct a CT/MRI three-dimensional image, the marker positioning stickers (usually 5-7) can be displayed on the image, a registration pen is used for clicking the body surface marker positioning stickers in the registration process, then the marker positioning sticker images are sequentially clicked on the CT/MRI three-dimensional image, and finally registration is completed.
The in vitro registration method has the advantages of higher alignment precision and lower requirements on the experience of operators, but has complex operation and longer time consumption, and the registration needs 5 to 10 minutes.
The single plane in vivo registration method is to select a slice (usually an axial plane) of the second image such as CT or MRI, and then perform an ultrasound scan to find the same slice as CT or MRI for image fusion. The anatomical structure required to be registered and aligned can be clearly displayed on the CT/MRI and the ultrasound image, blood vessels and the like (taking the liver as an example, the branches of portal veins and hepatic veins) are generally used as anatomical landmarks for configuring and aligning, and the CT/MRI image and the ultrasound image can be completely consistent in section, angle and orientation through operations such as rotation, translation and the like in the registration and alignment process, so that the registration can be successfully fused. The in-vivo registration method has high requirements on operators, and needs to be familiar with CT/MRI, PET and ultrasonic images to identify focuses and various anatomical structures, and requires the skill of an ultrasonic scanning technique and accurate and stable scanning section, so that the operation and training are difficult, and the training time and the learning curve are long. Furthermore, for organs that cannot be visualized by ultrasound, such as the lungs, bones, etc., and muscles, where anatomical landmarks are not apparent, and other superficial tissues, etc., image fusion cannot be performed using in vivo registration.
The single-plane in-vivo registration method has lower alignment precision than the former two methods, has high requirements on the working experience of operators and has long learning curve; the registration alignment of the beginner takes 30-40 minutes, even the registration of the skillet takes 5-10 minutes.
