Instruments, systems, implants, and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, and a mucosal resection device. A submucosal implant device for diagnosing and treating disorders of the body may be implanted. A passive submucosal implant device may take the form of a drug delivery depot in which a therapeutic agent within the depot elutes from the depot according to a predetermined elution profile. An active submucosal implant device may take the form of a drug delivery device that incorporates a self-contained diagnostic system to determine the appropriate delivery time and dosage of a therapeutic agent to be administered.

Instruments, systems and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, and a mucosal resection device. Systems include a combination of one or more of such instruments with or without injectable agents. Embodiments of various methods for performing the procedures are also provided. In accordance with one aspect there is provided a submucosal implant device for diagnosing and treating disorders of the body. The submucosal implant device may take the form of a gastric stimulator in which signals are supplied to the muscular wall of a mammal to treat motility disorders. In accordance with yet another aspect there is provided a method for performing a submucosal medical procedure to deploy a submucosal implant device in the digestive tract of a mammal.

The present invention discloses a task specific robot for the procedure of endoscopic submucosal dissection (ESD). This robot has two arms with nine degrees of freedom (DOF), and the capability of tissue elevation and dissection. An optimal design of these robot arms requires the use of shape memory alloy (SMA) wire and steel wire actuators to develop an improved actuation mechanism, which enables force to be transmitted to the distal tip of the robot arms for an efficient tissue elevation and dissection.

Systems, methods, and apparatuses for assisting with submucosal dissections include a retraction strip body. The retraction strip body is formed at least partially from a deformable material. The retraction strip body is capable of being selectively moved between a first condition and a second condition. In the first condition, the retraction strip body is capable of engaging a target patient tissue. In the second condition, the retraction strip body is capable of retracting the target patient tissue. At least one tissue engagement member is located on the retraction strip body.

The invention provides a tunnel support for endoscopic submucosal dissection. The tunnel support comprises an air bag, a tubing, a negative pressure tube, a lead guide tube and an inflatable tube; the negative pressure tube, the lead guide tube and the inflatable tube are located in the tubing; the air bag is located at the front end of the tubing; the negative pressure sucking tubes are lengthways arranged on two sides of the upper wall and the lower all of the air bag; outward negative pressure sucking holes which pass through the air bag wall to communicate with the outside are uniformly formed in the negative pressure sucking tubes at the two sides of the upper wall and the lower wall of the air bag; the inflatable tube communicates with the air bag; the negative pressure tube is connected with a negative pressure generator. The tunnel support is simple in structure, convenient and reliable to operate, and effective to support a tunnel during the endoscopic submucosal dissection, so as to greatly reduce perforation and injury on muscularis propria and other complications; in addition, the difficulty at surgery can be greatly reduced, the cutting efficiency can be improved, and meanwhile, the safety of the surgery can be improved.

The present disclosure relates to the field of endoscopy. In particular, the present disclosure relates to systems and methods suitable for resecting or dissecting large areas of mucosal or submucosal tissue. The system can apply tension to and continuously manipulate the mucosal tissue such that large lesions can be resected or dissected by a cutting element disposed at the distal end of the endoscope.

Embodiments of the present invention provide an operation process recording method, device, medium and computing device. The method includes: obtaining a plurality of operation sub-videos from the collected operation video, and determining the operation type corresponding to each operation sub-video; marking the target contained in each frame image in each of the identified operation sub-videos, and obtaining the recognition labeling information of the target; storing each frame of image and the video time corresponding to each frame of image, the operation type and the labeling information together to obtain operation process record information. The present invention can obtain the operation process record based on the operation video. When watching the operation video of the operation process with the operation process record, you can know more clearly the surgical instruments that need to be used in each step of the operation, as well as the operating scenes and lesions that will appear. , improve the application rate of endoscopic submucosal dissection video, and improve the training efficiency of endoscopic submucosal dissection.
