A neurosurgery system for probing brain tissue of a patient for tumorous tissue. The system including a suction tool, an excitation source, an optical instrument, and a controller. The suction tool including a suction cannula defining a lumen, an optical fiber configured to transmit fluorescence emitted by the brain tissue; and an indicator configured to selectively emit visible light. An excitation source is configured to emit an excitation light having a wavelength to induce the fluorescence in the tumorous tissue. The optical instrument is coupled to the optical fiber. The optical instrument configured to convert the fluorescence emitted by the brain tissue and transmitted by the optical and configured to determine that the brain tissue is tumorous based on the electrical signal and activate the indicator based on the determination.

This invention relates to the field of medical device technology, specifically disclosing a tumor resection device, including a resection mechanism, a body, a handle, a drive mechanism, a transmission mechanism, and an adsorption mechanism. The handle, body, and resection mechanism are sequentially connected. The drive mechanism is installed inside the handle, and the transmission mechanism is installed inside the body and connected to the drive mechanism and the resection mechanism. The drive mechanism drives the resection mechanism to perform tumor resection via the transmission mechanism. The adsorption mechanism is installed inside the handle and body, and when the resection mechanism removes the tumor, the adsorption mechanism removes the removed tumor. The tumor resection device has an elongated structure, and the maximum outer diameter of the cross-section of the tumor resection device is less than or equal to 10 mm. This invention's resection mechanism removes the tumor through the adsorption mechanism, effectively reducing the wound, alleviating patient pain, and lowering surgical risks.

This prostate treatment method includes an insertion step of inserting a balloon coated with a medicine into a urethra, an expansion step of expanding the balloon in a prostate part where the prostate is located in the urethra, and a step of injecting the medicine by piercing the prostate part with a microneedle attached to the surface of the balloon. This bladder tumor treatment method is for treating a bladder tumor having a tumor bulging part and a tumor bottom part, the bladder tumor treatment method being provided with a cutting step of cutting off the tumor bulging part, and a freezing step of freezing the tumor bottom part.

A neurosurgical system for examining a patient's brain tissue for tumor tissue. The system includes an aspiration instrument, an excitation source, an optical instrument, and a controller. The aspiration instrument includes an aspiration cannula defining a lumen, an optical fiber configured to transmit fluorescence emitted by the brain tissue, and an indicator configured to selectively emit visible light. The excitation source is configured to emit excitation light having a wavelength that induces fluorescence in the tumor tissue. The optical instrument is connected to the optical fiber. The optical instrument is configured to transduce the fluorescence emitted by the brain tissue and transmitted by the optical fiber, and is configured to determine that the brain tissue is tumorous based on the electrical signal and activate the indicator based on the determination.

The invention, which relates to the technical field of medical treatment, discloses an artificial intelligence automatic tumor identification system under fluorescence and white light comparison, comprising an image acquisition module, an image processing module, a feature analysis module and a visual interface module. The image acquisition module comprises a laparoscope unit and an endoscope unit and is used for acquiring image data in an operation process in real time; real-time image data is transmitted to the central processing unit through wired connection; the image processing module is responsible for preprocessing the acquired image data, including image denoising, contrast enhancement, artifact correction and data standardization, and removing noise in the image by adopting a filtering algorithm, and the filtering algorithm includes Gaussian filtering and mean filtering. Through accurate tumor recognition and real-time dynamic tracking, a doctor is helped to comprehensively resect tumors in an operation, the residual risk is reduced, and the operation success rate and the patient prognosis are improved.

A method for awake neurosurgical planning and testing includes presenting, to a subject undergoing an awake neurosurgical procedure, during the awake neurosurgical procedure, and using a head mountable device, tests for evaluating neurocognitive or motor functions controlled by a region of the subject's brain being evaluated for tumor resection. The method further includes receiving, by a test controller module, responses of the subject to the tests. The method further includes automatically selecting or generating, by the test controller module, and based on the responses, further tests to present to the subject during the awake neurosurgical procedure. The method further includes presenting, via the head mountable device and to the subject, the tests selected or generated based on the subject's responses.

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.
