Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
The embodiment of the invention provides an imaging navigation method for lymphatic venous anastomosis, which is shown in fig. 1 and comprises the following steps:
Step S1: respectively acquiring the operation progress and microscopic imaging of the lymphatic venous anastomosis; the surgical procedure includes: cutting the lymphadenitis part, searching lymphatic vessels and vein vessels, anastomosing the lymphatic vessels with the vein vessels, searching the lymph and vein, anastomosing the lymph and vein, and the like; microscopic imaging is an image captured by an operation microscope with a lens aligned with the lymphadenitis incision part;
Step S2: invoking a preset navigation mark strategy corresponding to the operation process; navigation marking strategies are strategies for performing navigation marking on microscopic imaging to assist a surgeon, such as: the operation process is to search lymphatic vessels and venous vessels, and the navigation marking strategy is to mark lymphatic vessels and venous vessels in microscopic imaging, for example: the operation process is to anastomose the lymphatic vessel with the vein, and mark the positions of the lymphatic vessel and the vein to be sutured in microscopic imaging;
step S3: based on a navigation marking strategy, the microscopic imaging is subjected to navigation marking, so that the tracer navigation of the lymphatic venous anastomosis is realized. After the navigation mark is carried out, a doctor can check microscopic imaging after the navigation mark, and assistance is obtained.
The working principle and the beneficial effects of the technical scheme are as follows:
The application carries out navigation marking on microscopic imaging based on a navigation marking strategy, saves time for an operator to search organs such as lymph, vein and the like by himself and plan and implement anastomosis operation, improves operation efficiency, and is more humanized at the same time.
In one embodiment, based on a navigation marking strategy, when the microscopic imaging is subjected to navigation marking, a non-disturbing area of a user in the microscopic imaging is avoided; the user is typically an operator; the non-disturbing area is an area which can cause interference to a user after navigation marking; when navigation marks are carried out, a do-not-disturb area is avoided, so that a user can efficiently and intensively execute an operation, the operation is more intelligent, and the applicability is improved;
Wherein, the determination steps of the do not disturb area are as follows:
performing content type identification on the microscopic imaging to obtain a plurality of content types; the content types include: lymphatic vessels, veins, muscles, fascia, etc.;
matching the content type with the trigger content type in a preset trigger content type library; the trigger content type is a type of content that may need to be avoided on microscopic imaging, such as: lymphatic vessels, veins, etc.;
When the matching is met, acquiring a preset first trigger weight corresponding to the trigger content type met by the matching; the first trigger weight represents the degree to be avoided of the content of the trigger content type on the microscopic imaging, and the larger the first trigger weight is, the larger the degree to be avoided is;
determining whether the first trigger weight is greater than or equal to a preset trigger weight threshold; the trigger weight threshold may be, for example: 75;
When yes, taking a local image area matched with the content type in the microscopic imaging as a do-not-disturb area; otherwise, acquiring a preset trigger weight library corresponding to the trigger content type matched with the trigger content type; when the first trigger weight is greater than or equal to the trigger weight threshold, the content of the trigger content type on the microscopic imaging needs to be avoided to a larger extent, and the corresponding local image area is directly used as a do-not-disturb area, for example: the triggering content type is lymphatic vessels and veins, and the lymphatic vessels and veins are necessarily avoided;
acquiring a plurality of user operations generated in a first time preset recently by a user; the user operation includes: surgical procedures and dialogue procedures; the first time may be, for example: 3 minutes;
Determining a second trigger weight corresponding to the user operation from the trigger weight library; the trigger weight library has second trigger weights corresponding to different user operations, and the second trigger weights represent the degree that the content of the trigger content type needs to be avoided on the displayed more trend microscopic imaging after the user operation is generated by the user, for example: the trigger content type is fascia, the user generates dialogue operation as 'accidental injury fascia', and the second trigger weight is 7;
Accumulating and calculating a second trigger weight corresponding to each user operation to obtain a trigger weight sum; the larger the trigger weight sum, the larger the overall degree that the content of the trigger content type needs to be avoided on the displayed more trend microscopic imaging after the user operation is generated by the representative user;
determining whether the trigger weight sum is greater than or equal to a preset weight sum threshold; the weights and thresholds may be, for example: 80;
when yes, the local image area is taken as a do-not-disturb area. When the trigger weight sum is greater than or equal to the weight sum and the threshold value, after the user operation is generated on the representative user, the overall degree that the content of the trigger content type needs to be avoided on the displayed more trend microscopic imaging is too high, and the local image area is taken as a do-not-disturb area.
When the do-not-disturb region is determined, a trigger content type library, a first trigger weight, a trigger weight library and the like are introduced, the do-not-disturb region is determined in a self-adaptive mode, and the accuracy and the applicability of the determination of the do-not-disturb region are improved by considering the importance degree of the content and the tendency degree of a user.
