    摘要： A probe for use with an endoscopic suction-irrigation instrument is disclosed which permits a second probe to be inserted therethrough. The suction-irrigation instrument has a cannula, a fluid chamber having at least one port for irrigation and suction and a proximal opening, and a first seal in the proximal end of the fluid chamber. The fluid chamber has a distal end communicating with the cannula. The probe has a proximal handle portion, a middle portion, and a hollow distal portion. The handle portion has an axial passageway and a second seal therein. The middle portion extends from the handle portion through the first seal at the end of the fluid chamber and through the fluid chamber. The middle portion has an outer diameter shaped to contact the first seal such that the proximal end of the fluid chamber is sealed. The middle portion is also shaped to be smaller than the inner diameter of the fluid chamber, and the middle portion is provided with a second axial internal passageway extending therethrough. The distal portion extends at least partially through the cannula and has an outer diameter smaller than the inner diameter of the cannula. A second probe may be inserted through the second seal of the first probe, through the axial passageway in the handle portion, through the internal passageway in the middle portion, and out through the distal portion and the cannula.

    摘要： An apparatus for counting the number of times a temperature cycle occurs includes an indicator having sequential indicia and a temperature responsive member for indicating a next one of the indicia. Mechanical, fluid mechanical and electronic versions of the invention are disclosed. In the mechanical version, the indicator can be a ratchet member having teeth, a pawl and a display surface containing indicia. A temperature responsive element such as a bimetallic member engages the teeth of the ratchet and advances the ratchet each time the apparatus is subjected to a preset temperature cycle. A housing with a window masks the display to indicate one of the indicia as advanced by the temperature responsive element. Preferred embodiments of the mechanical version include a ring-like ratchet member with interior teeth and an exterior display surface. The number of teeth is preferably one or more less than the number of indicia so that upon advancing the ratchet member to the last indicia, it can be advanced no further. The bimetallic element is mounted inside the ring and the housing covers the outer surface of the ring. A removable locking pin is provided to prevent movement of the ratchet member until activated.

    摘要： An apparatus for counting the number of times a medical instrument has been sterilized includes an indicator having sequential indicia and a heat responsive member for indicating a next one of the indicia. Mechanical, fluid mechanical and electronic versions of the invention are disclosed. In the mechanical version, the indicator can be a ratchet member having teeth, a pawl and a display surface containing indicia. A heat responsive element such as a bimetallic member engages the teeth of the ratchet and advances the ratchet each time the apparatus is subjected to the heat of sterilization. A housing with a window masks the display to indicate one of the indicia as advanced by the heat responsive element. Preferred embodiments of the mechanical version include a ring-like ratchet member with interior teeth and an exterior display surface. The number of teeth is preferably one or more less than the number of indicia so that upon advancing the ratchet member to the last indicia, it can be advanced no further. The bimetallic element is mounted inside the ring and the housing covers the outer surface of the ring. The housing may be formed from the ferrule of an endoscopic surgical instrument or may be formed as part of the handle of such an instrument. A removable locking pin is provided to prevent movement of the ratchet member during shipping and the locking pin may be coupled to packaging so that it is automatically removed when the surgical instrument is removed from its packaging.

    摘要： An improved use counter for endoscopic instruments is mounted in the ferrule of the distal portion of an endoscopic instrument having separable proximal and distal portions. The counter includes a ratchet wheel having inner and outer teeth and a bimetallic coil having a fixed end and a free end. The fixed end of the bimetallic coil is attached to a hub portion of the ferrule and the free end of the bimetallic coil engages the inner teeth of the ratchet wheel. An inwardly extending tooth in the ferrule engages the outer teeth of the ratchet wheel to prevent backward movement of the ratchet wheel. The outer surface of the ratchet wheel is also provided with incremental indicia viewable through a window in the ferrule. As the bimetallic coil is heated and cooled when the instrument is sterilized, the free end of the coil engages and advances one tooth of the ratchet wheel. Movement of the free end is preferably limited by stops. A spring biased locking and disabling pin is mounted in the ferrule and engages a stepped width portion of the ratchet wheel. The pin prevents advancement of the ratchet wheel during shipping and disables the instrument after a predetermined number of sterilizations.
