A surgical tool system including a tool unit and a first battery and control module and a second battery and control module. The tool unit includes a power generating unit and a head for supporting an energy applicator. The first battery and control module is configured to releasably receive the tool unit. The first battery and control module having a first shape so that when the tool unit is attached to the first battery and control module, the tool unit and the first battery and control module have a pencil-grip configuration. The second battery and control module is also configured to releasably receive the tool unit. The second battery and control module having a second shape so that when the tool unit is attached to the second battery and control module, the tool unit and the second battery and control module have a pistol-shaped configuration.

A cassette for collecting a tissue sample. The cassette includes a housing configured to be removably coupled with a manifold receiver of a medical fluid collection system. The housing defines a first void space, a second void space, and an outlet opening. A catch tray is removably positionable within the first void space and includes a screen defining porous features for collecting the tissue sample. A filter element separate from the catch tray is disposed within the second void space. The housing may include a cap portion defining the first void space, and a shell portion coupled to the cap portion and defining the second void space. The cassette may be simultaneously operable in a tissue collection mode in which fluid is suctioned across the catch tray to collect the tissue sample, and a bypass mode in which the fluid is not suctioned across the catch tray.

Methods of assembling a manifold for a medical waste collection system. A flapper valve unit is secured to a head of a cap. A filter element is positioned within a shell. Basket hands of the filter element are fitted between first pairs of ribs of the cap skirt. Fingers of the shell are fitted between second pairs of ribs of the cap skirt. The cap is secured to the shell to cover an open distal end of the shell. A drip stop is secured to the proximal end base of the shell to seat within the outlet opening. Ears may be fitted through holes defined by the flapper valve unit and cap holes defined by the cap so as to snap lock to the head of the cap. The hub of the flapper valve unit may be compressed with the ears snap locked to the head of the cap.

A surgical system comprises a handpiece and a battery. The handpiece includes a body, a handpiece controller, and a handpiece connector with a first coupler, a handpiece voltage terminal, and a handpiece data terminal. The battery has a housing, a cell, a battery controller, and a battery connector with a second coupler to rotatably engage the first coupler, a battery voltage terminal, and a battery data terminal. The second coupler receives the first coupler at an initial radial position and permits rotation to a first secured radial position and a second secured radial position. Rotation from the initial radial position to the first secured radial position engages the voltage terminals to transmit power between the cell and the handpiece controller, and rotation to the second secured radial position engages the data terminals to communicate data between the controllers while maintaining engagement between the voltage terminals.

Battery

A manifold apparatus and method of opening a valve in a medical/surgical waste collection unit. The manifold includes a base at a proximal end with the base defining an opening off center from an axis of the manifold. The manifold further includes two arcuately spaced tabs, each subtending arcs having different arcuate lengths. The manifold is positioned such that the tabs mate with at least two slots of a lock ring of the waste collection unit so as to cause the opening of the manifold to be, upon insertion into a bore of the waste collection unit, in a specific rotational alignment in the bore. The manifold is rotated within the bore to cause a valve disk to move between a first position in which the valve disk blocks fluid flow through the receiver and a second position in which the valve disk allows fluid flow through the receiver.

Removable manifold for a medical/surgical waste collection unit

A manifold for a medical/surgical waste collection assembly. The manifold includes a housing shaped to be removably received within a manifold receiver of the medical/surgical waste collection assembly. An inlet fitting is coupled to the housing and adapted to be coupled with a suction line. An outlet opening is in fluid communication with the inlet fitting to define a fluid communication path from the suction line to the outlet opening and through a filter. The manifold includes a data carrier storing data useable to regulate operation of the medical/surgical waste collection assembly. The data carrier may include a radiofrequency identification tag having memory storing data suitable for determining whether the manifold is usable with the medical/surgical waste collection assembly. The RFID tag is adapted to be in electronic communication with a data reader when the manifold is coupled with the manifold receiver for communicating the data from the manifold.

A powered surgical tool with a switch for regulating tool operation. A pair of opposed arms extend outwardly from opposed sides of the switch. The arms move between safety and run states. When the arms are in the safety state, the arms engage a static surface to prevent movement of the switch. When in the arms are in the run state the arms are spaced from the static surface so movement is allowed. The arms are connected together so that the movement of one arm results in simultaneous movement of the other arm.

A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.

A cassette () for use with a medical waste collection system (). The cassette includes a housing () shaped to be removably attached to a receptacle () integral with the housing. A sleeve () is attached to the cassette so as to be located forward of the housing. The sleeve is formed with a void space. A fitting () for collection to a suction line is attached to the sleeve. A screen () is removably fitted in the sleeve void space. The screen is fitted in the sleeve void space when it is desirable to catch tissue that may be entrained in the fluid stream from the suction line.

A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.
