A method for capturing an object in a cavity in a patient is described. The method includes advancing a ureteroscope into the cavity containing the object. A basket is advanced through a working channel of the ureteroscope. The basket is opened within the cavity and is positioned so as to enclose the object. Then, two actions are performed simultaneously. The basket is collapsed while simultaneously the basket tool is advanced forward so that the object remains within the basket, ideally near the center of the basket, as the basket closes around the object. Once the object is captured, the basket is retracted to remove the object out of the cavity. Further, this process may be automated by having the method carried out by robotic arms acting in tandem, with one or more robotic arms advancing the basket tool or ureteroscope, and another robotic arm collapsing the basket.

A device for extracting objects from the body, such as urinary stones, using a low pressure inflatable toroidal balloon that serves to engulf the object during extraction while dilating and protecting the passageway. The balloon loads onto an ureteroscope prior to insertion, rather than through the ureteroscope as do existing balloons. The toroidal balloon is a simple and unique device that may be applied external to the extracting telescope and does not interfere with existing methods for stone manipulation such as laser lithotripsy, irrigation and basket extraction in the case of urinary stone manipulation.

The invention discloses a combined rigid ureteroscope which comprises a rigid ureteroscope body and a tubular sheath which is sheathed outside a tubular part of the ureteroscope body, wherein a starting end of the sheath is tightly attached to the tubular part of the ureteroscope body; the rear end of the sheath is equipped with a locking mechanism; a locking part is arranged between the tubular part and an operation part of the ureteroscope body; and the locking mechanism is matched with the locking part so as to lock or loosen the rigid ureteroscope body and the tubular sheath. By adopting the combined rigid ureteroscope,, the locking mechanism between the ureteroscope body and the sheath can be loosened during operations for examination, diagnosis and treatment of ureter and kidney, the rigid ureteroscope body and the sheath can be separated, and the sheath is left in the ureter and utilized as a channel through which broken stones can be repeatedly taken out for multiple times or the ureteroscope body separately gets in and out of the ureter as well as an operation channel of a flexible ureteroscope, thereby saving the operation procedures, shortening the operation time and improving the operation safety; and moreover, in some operation procedures, the rigid ureteroscope can be used instead to implement projects that must be implemented by the flexible ureteroscope before,thereby avoiding the problems of difficult operation and easy damage of the flexible ureteroscope, and actually realizing safe, effective and low-cost clinical treatment.

A method for creating a tract in retrograde fashion for nephrostomy tube creation comprising the steps of providing a puncture wire having a tissue penetrating tip shielded in a sheath, inserting the puncture wire and sheath through a channel in an ureteroscope, advancing the puncture wire from the sheath while visualizing under direct vision a position of the puncture wire, advancing the puncture wire through a selected calyx, and inserting antegrade a coaxial catheter over the puncture wire.

The invention discloses a minimally-invasive interventional operation robot for the urinary surgery. A flexible ureteroscope lifting module comprises a lifting table and a linear module fixing rack, the lifting table can adjust the height of a flexible ureteroscope and a sickbed, and the fixing rack is connected with the lifting table and a linear module; a flexible ureteroscope pushing module comprises a pushing mechanism and a flexible ureteroscope supporting mechanism, and can be used for pushing the flexile ureteroscope, and the supporting mechanism is used for providing a flexible part supporting force for the flexible ureteroscope; a flexible ureteroscope rotating module comprises a rotating shaft and a gear and drives the rotating shaft to rotate through rotation of a motor; a flexible ureteroscope bending module comprises flexible ureteroscope fixing support, a flexible ureteroscope carrying platform and a U-type knob which is matched with a flexible ureteroscope bending knob,and the flexible ureteroscope bending knob rotates along with rotation of the U-type knob. The minimally-invasive interventional operation robot can help a doctor to operate the flexible ureteroscopecorrespondingly during the surgery, relieve fatigue caused by the long-time surgery of the doctor, increase the speed of the surgery, and collect force data of flexible ureteroscope motion during thesurgery.
