A device combining positioning and injection systems for injection within a body cavity, comprises: a tubular housing surrounding an accommodating space and having an opening hole fluidly connected to the accommodating space; a curved channel fluidly connected to the accommodating space and the opening hole; an injection needle disposed inside the accommodating space and the curved channel; the injection needle having a piercing portion penetrating through the opening hole and configured to extend outward from or retract inward into the opening hole; a plurality of ultrasonic transducers installed at the tubular housing and at two opposite sides of the opening hole; wherein at least one of the ultrasonic transducers being used to transmit a detection signal, and at least one of the ultrasonic transducers being used to receive the detection signal; a monitoring unit connected to the ultrasonic transducers via a transmission unit for information transmission therebetween.

A method is described for performing a percutaneous operation on a patient to remove an object from a cavity within the patient. The method includes advancing a first alignment sensor into the cavity through a patient lumen. The first alignment sensor provides its position and orientation in free space in real time. The alignment sensor is manipulated until it is located in proximity to the object. A percutaneous opening is made in the patient with a surgical tool, where the surgical tool includes a second alignment sensor that provides the position and orientation of the surgical tool in free space in real time. The surgical tool is directed towards the object using data provided by both the first and the second alignment sensors.

The present technology relates to a surgery system, a control method, a surgical apparatus, and a program that allow easy updating of a function of a medical apparatus. A configuration includes an information processor, and a surgical apparatus. The information processor includes a storage section storing an application, and a transmission section transmitting, in response to a request from the surgical apparatus, the application stored in the storage section. The surgical apparatus includes a reception section receiving the application transmitted by the transmission section, and an execution section executing the application received by the reception section.

Systems and methods for controlling an irrigation flow rate during a lithotripsy procedure are provided. The system includes a laser configured for lithotripsy procedure, a lithotripsy irrigation system, and a temperature sensor configured to provide input to enable control of a flow of the lithotripsy irrigation system in response to a change in temperature from the operation of the laser.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A surgical device comprises an elongate shaft (12) which extends from a proximal end region to a distal end region thereof, the shaft (12) defining a first lumen (14) for receiving an elongate camera device therein, a second lumen (16) for receiving a tissue manipulation device therein, and a third lumen (18) for receiving a tissue retrieval device therein, the first, second and third lumens (14, 16, 18) extending from the proximal end region to the distal end region of the elongate shaft, and having respective open ends at the distal end region of the elongate shaft. The surgical device further comprises an elongate camera device which extends along the first lumen, a tissue manipulation device which extends along the second lumen, and a tissue retrieval device which extends along the third lumen.
