Detailed Description
The principles and spirit of the present specification will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present description, and are not intended to limit the scope of the present description in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Those skilled in the art will appreciate that the embodiments of the present description may be implemented as a system, apparatus, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: complete hardware, complete software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Embodiments of the present specification provide an automated surgical system. Fig. 1 shows a schematic diagram of an application scenario of an automatic surgical system in an embodiment of the present specification. As shown in fig. 1, the automated surgical system may include two parts, a surgical robotic system 10 and a visual guidance system 20.
The surgical robotic system 10 may include three parts, a doctor trolley 101, an image trolley 102, and a surgical trolley 103. Wherein the image trolley 102 may be used to acquire intraoperative real-time surgical images and communicate the surgical images to the visual guidance system 20 for processing. The doctor acquires visual decision data processed by the visual guidance system on the display screen of the doctor trolley 101, and adjusts or confirms the visual decision data. The surgical trolley 103 is used to perform an automated surgical operation.
The visual guidance system 20 may comprise two parts, an image processing host 201 and a display 202. The image processing host 201 may be used to process the endoscopic surgery image transmitted from the image trolley 102, and transmit the visual decision data obtained after processing to the doctor trolley 101 for the doctor to make a decision, so as to obtain adjusted visual decision data. Visual decision data may include target location, path planning, object location data, and the like. The adjusted visual decision data is returned to the visual guidance system 20. The vision guidance system 20 matches the adjusted vision decision data to the endoscope image coordinate system to obtain the target decision data. Specifically, after the doctor adjusts the visual decision data at the display end, the doctor converts the position under the display image coordinate system into the position under the endoscope image coordinate system through the conversion matrix for the adjusted visual decision data, so that the target decision data can be obtained. The image processing host 201 of the vision guidance system 20 can also perform recognition processing on the endoscopic surgery image to obtain real-time vision information. The real-time visual information may include operation object information and visual operation-related information. The display 202 may present visual decision data and display real-time visual information in real-time.
The vision guidance system 20 can send real-time vision information to the doctor trolley 101 for display, so that the doctor can grasp more operation information, and the vision decision data can be better adjusted. The vision guidance system 20 may also transmit real-time visual information and target decision data to the surgical trolley 103 for automated surgical procedures.
Referring to fig. 2, a scene graph of visual guidance system result presentation is shown. As shown in fig. 2, the display 202 of the visual guidance system 20 may be used to present all of the processing results of the visual guidance system 20, including: visual decision data and real-time visual information. The display 202 may also display a surgical scene, where the surgical scene may be endoscopic image data acquired from an image trolley.
Referring to fig. 3, a physician-end visual decision rendering and adjustment rendering scene graph is shown. As shown in fig. 3, a doctor may acquire visual decision data and choose whether to adjust the visual decision data at the doctor trolley 101. Likewise, the doctor trolley 101 may also display the surgical scene and real-time visual information.

In other embodiments, the scene acquisition system may be an in vitro camera system. The target surgical scene data may include intra-operative image data acquired by a scene acquisition system. The scene acquisition system 401 may send the target surgical scene data to the visual guidance system 402. In one embodiment, the scene acquisition system 401 may send the intraoperative image data to the vision guidance system 402 via the image trolley 102.
The visual guidance system 402 may be used to obtain targeted surgical information. The target surgical information may include information of a surgical type, a surgical stage, and the like. The visual guidance system 402 may receive the target surgical scene data and generate visual decision data based on the target surgical scene data and the target surgical information. Visual decision data may include decision-making scheme data for performing a current surgical task or surgical subtask, may include target location, path planning, object-of-operation location data, and the like. The visual guidance system 402 may send the visual decision data to the interactive decision system 403.
The interactive decision system 403 may be configured to receive the visual decision data and graphically display the visual decision data. In one embodiment, the interactive decision system 403 may be provided in the physician's trolley 101. In the event that the physician decides to adjust the visual decision data, the interactive decision system 403 may receive a protocol adjustment instruction entered by the physician. Illustratively, the scheme adjustment instruction may include at least one of: target deletion instructions, target addition instructions, path sequence adjustment instructions, decision making instructions and the like. The interactive decision system 403 may generate adjusted visual decision data based on the regimen adjustment instructions and the visual decision data and send the adjusted visual decision data to the visual guidance system 402. The visual guidance system 402 may generate target decision data based on the received adjusted visual decision data. The visual guidance system 402 may then send the target decision data to the motion control system 404.
The motion control system 404 may be used to control a surgical instrument to perform a surgical operation in accordance with the target decision data. In one embodiment, the motion control system 404 may be disposed in the surgical trolley 103. The motion control system 404 may be used to control surgical instrument or endoscope motion on a robotic arm on a surgical trolley to perform a surgical procedure.
In the above embodiment, after the visual guiding system generates the visual decision data, the visual decision data may be sent to the interactive decision system for adjustment, so as to obtain target decision data more in line with the operation standard and the operation requirement, and automatic operation is performed based on the adjusted target decision data, so that the operation risk may be reduced, and the operation quality may be improved.
In some embodiments of the present description, the interactive decision system 403 may be used to present at least one decision adjustment control to a physician. The interactive decision system 403 may be further configured to display a corresponding decision adjustment user interface in response to a clicking operation of at least one decision adjustment control by the doctor to generate adjusted visual decision data based on the adjustment operation entered by the doctor. The at least one decision adjustment control comprises at least: target point adjustment control, target point adding and deleting control and path optimization control.
Referring to fig. 5, a schematic diagram of a user interface of an interactive decision system in an embodiment of the present description is shown. As shown in fig. 5, visual decision data may be displayed in the user interface of the interactive decision system 403, and a plurality of adjustment controls may also be displayed: adjustment 1 and adjustment 2 … … adjust n. Wherein the plurality of decision adjustment controls comprises at least: target point adjustment control, target point adding and deleting control and path optimization control. The target point adjustment control is used to adjust the position of the target point, e.g., the position data of the target point can be modified. The target adding and deleting control can be used for deleting targets or adding targets. The path optimization control may adjust the surgical execution path. After the doctor triggers a certain adjustment control, the interactive decision system 403 may display a corresponding visual decision data adjustment interface on the user interface, and generate adjusted visual decision data based on the adjustment operation entered by the doctor. After the physician has completed the adjustment, the confirmation control of fig. 5 may be clicked on to send the adjusted visual decision data to the visual guidance system 402.
Referring to fig. 6, a schematic diagram of visual decision data adjustment in an embodiment of the present disclosure is shown. FIG. 6 illustrates the manipulation of target spot adjustments or target spot additions and deletions during a suturing procedure. The left side of fig. 6 is a schematic diagram of visual decision data sent by the visual guidance system to the interactive decision system. Wherein, the solid circle is the suturing target spot with good visual decision effect, and the dotted circle is the suturing target spot with poor visual decision effect. The middle diagram of fig. 6 shows the interaction of the decision system to adjust or add/delete the target according to the doctor's operation. As shown in fig. 6, targets that are not effective can be adjusted by dragging, adding or deleting. The right side of fig. 6 shows a schematic diagram of the adjusted visual decision data. Target point selection in the adjusted visual decision data better meets the requirements of suture operation.
Referring to fig. 7, a schematic diagram of visual decision data adjustment in an embodiment of the present disclosure is shown. FIG. 7 illustrates the operation of target retrieval path optimization in tissue retrieval surgery. The left side of fig. 7 is a schematic diagram of visual decision data sent by the visual guidance system to the interactive decision system. Wherein the total length of the path of the visual decision is not shortest and there is a risk of collision with the robot arm. Thus, the physician can adjust it. The right side of fig. 7 shows a schematic diagram of the adjusted visual decision data. The doctor optimizes the result, modifies the sequence of tissue recovery, and selects and breaks targets which may cause the collision of the mechanical arm. Specifically, the recovery sequence of the No. 1 and No. 2 targets is exchanged, the No. 6 target is deleted, and recovery is not performed. The optimized result improves the operation efficiency and ensures the experiment safety. Doctors have the function of supervising and optimizing the operation tasks.
In some embodiments of the present description, the interactive decision system is further configured to present decision-making controls to a physician; in response to a selected operation of the decision-making control by the physician, the interactive decision-making system is further configured to generate decision-making data from the operation data entered by the physician, and to send the decision-making data to the visual guidance system.
For some simpler surgical tasks, or when visual decision-making is poor, a decision-making scheme can be directly made by the physician at the interactive decision-making system. The decision mode mainly depends on personal operation experience of doctors, and has the advantages that on one hand, the dependence on a vision algorithm system can be reduced, and the calculation pressure of a server is reduced; on the one hand, the vision guidance system is complemented, and when the vision algorithm is poor, the normal execution of the operation can be ensured depending on the decision of a doctor.
Referring to fig. 8, a schematic diagram of the direct visual decision making data of a traditional Chinese medicine in an embodiment of the present specification is shown. The cholecystectomy task is shown in fig. 8. Because the task only needs to specify 5 target points and the target point positions are easy to identify, the doctor can directly specify the target point positions. The vision guiding system only needs to continuously track the target position in the follow-up operation, and the target position is updated in real time.
Referring to fig. 9, a schematic diagram of the direct visual decision making data of a traditional Chinese medicine in the embodiments of the present description is shown. As shown in fig. 9, is a cholecystectomy task. The common pig only has one blood vessel and gall bladder tube, and the vision guidance system can be normally identified. However, there are pigs with two blood vessels and one blood vessel, and the visual guidance system has poor detection results due to lack of related data. At this time, the doctor can directly designate the position of the blood vessel by using external equipment on the display, so that the smooth execution of the operation task is ensured.
In some embodiments of the present disclosure, the visual guidance system 402 may be specifically configured to query a pre-constructed visual decision criteria library for target visual decision criteria data corresponding to the target surgical information. The vision guidance system 402 may be further specifically configured to calculate the target surgical information and the target surgical scene data by using a vision decision algorithm under the constraint of the target vision decision standard data, so as to obtain vision decision data. The visual decision standard library comprises visual decision standard data corresponding to each operation type in a plurality of operation types. The visual guidance system 402 may also be used to send the target visual decision criteria data to the interactive decision system 403. The interactive decision system 403 may also be used to display the target visual decision criteria data to a physician.
Referring to FIG. 10, a schematic diagram of a visual decision criteria library in an embodiment of the present disclosure is shown. A library of visual decision criteria for an automated surgical system may be constructed, establishing criteria in accordance with international medical performance criteria for all types of automated surgery for which automated surgical systems are currently available. The visual decision standard library is used as a visual guidance system execution standard on one hand and is used for outputting visual results conforming to actual medical operation; on the other hand, the visual effect of the doctor decision can be used as an auxiliary reference for the quality of the visual effect of the doctor decision, and the visual effect can be called out at the doctor end for the doctor to check, as shown in fig. 5. The setting of the visual decision standard library is beneficial to improving the consistency and the effectiveness of automatic operation, so that the result of the automatic operation can be dependent.
In some embodiments of the present disclosure, to further improve the accuracy of the visual decision criteria library, different visual decision criteria data may be set for different patient individuals, different surgical scenarios, different surgical organizations, and different surgical modes. For example, the individual patients are distinguished by data such as different sexes, different age groups, different body weights, etc. For different surgical scenes, that is, for different surgical corresponding parts, for example, different scenes such as heart, cholecyst tube, ureter, liver and the like, the corresponding standards of the same surgical type are different. The criteria may also be different for different surgical tissues, e.g., for different tissue locations in the heart. Different standard data are set for different surgical modes, i.e. different surgical types. By setting the visual decision standard library, the automatic operation visual decision evaluation standard can be specialized, different standards are provided according to different information of individual patients, operation scenes, operation positions, operation modes and the like, and the automatic operation visual decision evaluation standard library has individuation and specificity standards, better accords with the actual operation conditions of the patients, and is beneficial to improving operation quality.
As shown in fig. 10, for example, the automated organization recycling standard library includes: 1) Organization reclamation execution condition judgment standard: determining what the conditions for performing the automatic tissue reclamation operation are, such as the number n of tissues to be reclaimed that meet reclamation criteria in the field of view, no shielding around the tissues to be reclaimed, and so on; 2) Recovery tissue size determination: defining the size of tissue that can be autonomously retrieved by the robotic arm, e.g., tissue having a tissue diameter within [ a, b ] millimeters can be retrieved; 3) Organization recovery order criteria: for a plurality of tissues to be recovered in the visual field range, the recovery standard and the like are executed according to the rules of closest distance to the mechanical arm, shortest moving total path, no instrument collision, no tissue collision and the like.
In some embodiments of the present description, the visual guidance system may be further configured to generate real-time visual information based on the target surgical scene data, and send the real-time visual information to the interactive decision system, the real-time visual information including operation object information and visual operation association information; the interactive decision system is used for displaying the operation object information and the visual operation related information to a doctor; the interactive decision system is also used for acquiring and displaying the target operation information.
The vision guidance system may generate real-time visual information based on the target surgical scene data. The real-time visual information herein may include operation object information and visual operation-related information. The operation object information here may include position information, shape information, and the like of an operation object in surgery. The visual operation-related information may be information related to an operation in a surgical procedure, such as whether a surgical instrument is successfully held during a suture operation. The real-time visual information may also include location data of key points during the surgical procedure. The key points here may include operation object position data, operation instrument position data, key tissue position data, and the like in the target decision data.
In one embodiment, a target tracking algorithm may be employed to generate the implementation visual information based on target surgical scene data received in real-time. The target tracking algorithm may be implemented by a tracking model generated using a deep learning algorithm. Referring to fig. 11, a schematic diagram of generating real-time visual information based on the target surgical scene data in an embodiment of the present disclosure is shown.
