A medical instrument comprising a Veress needle, a dilating obturator, and a cannula. The Veress needle has a tubular safety obturator with an opening in its front section at a needle tip of the Veress needle. A guide with a guide slot can be positioned in a patient's vagina against the posterior fornix of the vagina to guide the Veress needle through the vaginal and peritoneal walls. A guide wire may be passed through the Veress needle and through the hole in the peritoneum wall formed by the Veress needle to guide the dilating obturator through the hole.

Medical instrument system for piercing through tissue

Mini-rigid ureteroscope

An endoscope having an elongated shaft which terminates in a deflectable distal tip is shown. The elongated shaft includes a first elongated sheath tube having a deflectable distal section. The deflectable distal section terminates in a distal tip having a triangular shaped cross-sectional area. The elongated shaft also includes a second semi-rigid elongated tube which is shorter in length than the first elongated sheath tube. The difference in length enables the deflectable distal section to extend beyond the end of the second semi-rigid elongated sheath tube and to be deflectable. The second semi-rigid elongated sheath tube encloses the proximal section of the first elongated sheath tube. The second semi-rigid elongated sheath tube has a generally rounded cross-sectional area which is slightly greater than that of the cross-sectional area of the first elongated sheath tube which enables the distal end of the second semi-rigid elongated sheath tube to enclose and pass therethrough the first elongated sheath tube. A method for performing a procedure in a cavity or passageway is also shown. A method for casting a housing around an endoscope frame is shown. An image means for an instrument having a rod-like image transferring system which is rigidly attached at a selected location is shown.

Endoscope having a deflectable distal section and a semi-rigid proximal

A method for casting a housing around an endoscope frame is shown. The method includes the step of assembling an endoscope frame comprising a proximal end of an elongated shaft having a first working channel, a second working channel, a fiber optical image bundle channel, and fiber optic light carrying member. Each of the working channels and the fiber optic light carrying member extend in a predetermined direction from the elongated shaft to a preselected location wherein each of the working channels are terminated in an input opening member. The fiber optic image bundle terminates in a viewing member. The fiber optic light carrying member terminates in a light connecting member. The method then comprises the step of casting with a curable material a housing having a predetermined shape and exterior outer surface around the endoscope frame including the proximal end of an elongated shaft, a first working channel, a second working channel, a fiber optic image bundle channel and a fiber optic light carrying member such that the input opening member of eacb working channel and a light connecting member of the fiber optic light carrying member extend through the exterior outer surface at separate and distinct locations which are positioned in a spaced relationship from the exterior outer surface and with a viewing member for terminating the fiber optic image bundle positioned interiorly within the housing, all of which form a fluid tight seal with the housing.

Resectoscope electrode

Combined resectoscope handle and latch

A system for reducing drag in a resectoscope working element. A hole is provided at a proximal end of a substantially enclosed electrode sheath for exiting fluids and substantially preventing pressure from being generated in the sheath. A working element has a guide block with a guide bar channel having a first cross-sectional shape and a guide bar with a second cross-sectional shape such that there are spaces between the guide bar and the guide bar channel and the bearing surfaces therebetween are relatively small.

System for reducing drag on the movement of an electrode in a

An electrode for use with a urological endoscope and a method for making the same. The electrode comprises an electrode lead, an electrode end and an electrode stabilizer. The stabilizer can stabilize the electrode proximate a distal region of a telescope and is made of a resilient material for resiliently mounting the electrode to the telescope. The electrode lead and electrode end can be made from a single conductor.
