The invention provides an intraoperative path optimization method and system based on solid tumor preoperative image analysis, and the method comprises the steps: constructing a three-dimensional model of a tumor and peripheral blood vessels and nerves according to a preoperative image, and carrying out the dissection risk marking of the three-dimensional model through a deep learning model, generating an anatomical risk image with risk gradient value distribution; taking the minimum intraoperative bleeding amount and the highest tumor excision rate as a reward function, combining the three-dimensional model, an anatomical risk image and historical similar case data, and simulating multiple operation paths based on an adversarial reinforcement learning algorithm to obtain an optimal operation path; the method comprises the following steps: acquiring the pose, ultrasonic image and fluorescence image of a surgical instrument in real time during surgery, matching the preoperative image with the intraoperative image based on a biomechanical model driven non-rigid registration algorithm, predicting organ displacement, and correcting an optimal surgical path, thereby avoiding accidental injury of key tissues, ensuring that an infiltration area is brought into the surgical path in time, and improving the surgical efficiency. Residues are reduced, and static planning failure is avoided.

The invention relates to the field of dermatology, and provides a rapid skin tumor resection tool aiming at the technical problem that an existing resection device is low in use efficiency, the rapid skin tumor resection tool comprises a shell with the inner area divided into a front end cavity, a middle end cavity and a rear end cavity, a front cover and a rear cover are rotationally connected to the positions, located outside the front end cavity and the rear end cavity, of the shell, the cutting device is arranged in the shell, and the cutting device comprises a high-pressure gas driving module which is arranged in the rear end cavity and extends to the middle end cavity; the homologous driving type displacement and rotary excision module is arranged in the front end cavity and is communicated with the high-pressure gas driving module; and the synchronous collection module is arranged in the front-end cavity. High-pressure gas is adopted as a power source of the excision device, generated chippings and blood can be blown away in time, the surgical field is kept in a clean state all the time, the tumor can be rapidly and accurately excided, and the use efficiency is high.

A method for treating a tumor excise site defined by a center and edges is described. The method includes simultaneously exposing the tumor site to radiation and pulsating heat. Also described is a device for treating tumors at a target site. The device includes a first balloon containing a radio isotope and a second balloon encasing the first balloon. The second balloon defines structures to create a void between the first balloon and the second balloon such that pulsing, temperature treated fluid traverses the void.

A method for treating a tumor excise site defined by a center and edges is described. The method includes simultaneously exposing the tumor site to radiation containing fluid and pulsating thermally treated fluid, wherein the fluids are separate from each other and confined to a balloon. Also disclosed is a device for treating a tumor excise site defined by a center and edges. The device includes a reversibly deformable container positioned at the center, the container encapsulating thermally treated fluid; a first drainage conduit; and a second radio-isotope containing conduit contacting a second longitudinally extending surface of the first drainage conduit so as to be positioned between the first drainage conduit and the center.

The design points of the design product: in shape. 4. The picture or photo that best indicates the design points: Design 1 Solid Drawing 1. 5. Design 1 is designated as the basic design.

A magnetic type sterile anti-permeation reusable anti-slip retaining pocket comprises retaining pocket cloth, a surgical operation opening is formed in the retaining pocket cloth, double rows of magnetic buckles are installed at the tail end of the retaining pocket and embedded into the retaining pocket cloth, and the size of the exposed area of a surgical site can be adjusted through magnetic buckling of the magnetic buckles at different positions. Side pockets are arranged on the two sides of the front face of the pocket blocking cloth, and the pocket blocking cloth is of a three-layer structure and comprises bottom-layer twill, middle-layer waterproof cloth and surface-layer twill. The surface layer and the bottom layer of the pocket blocking cloth are made of twill cloth, the middle layer of the pocket blocking cloth is made of waterproof cloth, and the pocket blocking cloth is waterproof, capable of preventing blood pollution, soft in material, convenient to use and capable of being repeatedly used, saves resources, achieves the principle of timely isolation of tumor resection positions and has the effect of preventing tumor diffusion pollution.

A multi-axis tumor excision marker system is configured to deposit markers along multiple axes radially about a tumor to define a boundary of margin tissue for excision. A catheter may deploy a marker extension that extends to a margin tissue boundary for depositing the marker. The marker extension may be a shape memory material that extends radially outward from catheter opening or may be directed radially outward by a guide head. The radiopaque marker may be a phase change marker, such as an adhesive that changes from a liquid to a solid. A marker may be a discrete marker and may have an extension portion that extends from an anchor portion. An envelopment marker has a plurality of marker extensions that each extend along an offset axis from each other. A spiral maker includes a maker extension that spirals around the margin boundary tissue.

The utility model discloses a minimally invasive excision device for urinary surgery tumor, which comprises a device main body, the device main body is composed of a resectoscope main body and a resectoscope sheath, one end of the resectoscope main body is provided with a main channel catheter, one end of the main channel catheter penetrates through the resectoscope sheath and extends to the outer side of the resectoscope sheath, and the other end of the main channel catheter is provided with a guide tube. A fixed sleeve is fixedly mounted on the surface of the other end of the resectoscope main body through a bolt; a surgeon holds a guide handle to guide more flexibly, a fixed sleeve, a movable sleeve, a lantern ring supporting piece, a thumb ring, an I-shaped connecting piece, an electrode knife rod and a torsional spring are arranged in a matched mode, the strength of a supporting point is increased when the electrotome head conducts tumor excision, the surgeon presses and pinches the distance between the handle ring and the thumb ring according to needs, and the torsional spring rebounds; and the movable sleeve stably slides on the surface of the guide rod, the movable sleeve drives the electrode cutter rod to stably support, and the working difficulty of tumor operation excision is reduced.

The present invention provides methods for detecting and predicting minimal residual disease in a subject who has undergone tumor resection surgery. Methods of the invention utilize a personalized cutoff for determining the likelihood for MRD.
