An electrically operated surgical instalment includes a surgical end effector having an actuation assembly effecting a surgical procedure when actuated and a handle connected to the end effector for actuating the assembly. A part of the assembly moves between start and fully actuated positions. The handle has a self-contained power supply and a drive assembly disposed entirely within the handle. The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.

Electrically Self-Powered Surgical Instrument with Manual Release

A hand-held, electrically powered and controlled surgical stapler/cutter includes a handle shaped to fit in one hand of a user and a surgical end effector connected to the handle. The handle contains therein a selectively actuated, self-contained electric power supply having at least one battery cell, at least part of an anvil control assembly, and at least part of an electrically-powered stapler/cutter control assembly electrically connected to the power supply. The surgical end effector is operatively connected to each of the anvil control assembly and the stapler/cutter control assembly. The stapler/cutter control assembly staples and cuts tissue disposed at the surgical end effector when powered by the power supply.

Electrical Surgical Instrument with Optimized Power Supply and Drive

A method for operating a surgical instrument (1), which comprises providing a surgical end effector (60) at a distal end of a handle (10) of the surgical instrument (1); electrically connecting an authentication controller within the handle (10) to a receiving portion of the end effector (60); removably placing an interchangeable part (50, 2200) at the receiving portion; and authenticating the interchangeable part (50, 2200) with the authentication controller when the interchangeable part (50, 2200) is seated in the end effector (60).

Electrical surgical instrument

A surgical instrument includes a surgical end effector having a receiving portion for removably receiving therein an interchangeable part. The receiving portion has a communication connection. A handle connected to the end effector actuates the end effector. The handle has a controller electrically connected to the communication connection for authenticating the interchangeable part when placed at the end effector. An interchangeable part is removably connected to the receiving portion and has an encryption device electrically removably connected to the communication connection when placed at the receiving portion. The encryption device authenticates the interchangeable part when queried by the electric controller.

Electrically self-powered surgical instrument with cryptographic identification of interchangeable part

A method for encrypted authentication of interchangeable parts of a surgical instrument includes providing a surgical end effector at a distal end of a handle of the surgical instrument and electrically connecting an authentication controller within the handle to a receiving portion of the end effector. An interchangeable part is removably placed at the receiving portion. The interchangeable part is authenticated with the authentication controller when the interchangeable part is seated in the end effector.

Methods for cryptographic identification of interchangeable parts for surgical instruments

A typical treatment system for use with tip embodiments includes an optical energy source, such as, for example, a laser A set of tips may be interchangeably attached to the treatment system, for example to alter the system parameters and the treatment provided through the individual tips Embodiments of the present invention include tips with a security chip and/or a memory A security chip protects the treatment system from use with unauthorized tips, and the memory stores information about the tips and/or the treatment system to enhance the treatment

Interchangeable Tips for Medical Laser Treatments and Methods for Using Same

The present invention relates to a method and apparatus for using an imaging detector to image an optical pattern created by illumination of a viscous material that is applied to the skin. The viscous material forms a detectable pattern that can be imaged by the imaging detector. In some examples, the viscous material is reflective and allows reflection from an illumination source to create an optical pattern on the imaging detector. In other cases, the variation in thickness of an absorbing or scattering viscous substance can be imaged by the detector. Polarized illumination and detection can be used to enhance the response.

Method and apparatus for monitoring and controlling laser-induced tissue treatment

A method and apparatus for thermal treatment of tissue by irradiating the skin with electromagnetic energy is disclosed. Sources of electromagnetic energy include radio frequency (RF) generators, lasers, and flashlamps. The apparatus includes either a positional sensor or a dosage evaluation sensor, or both types of sensors. These sensors provide feedback to a controller. The controller may control the electromagnetic source parameters, the electromagnetic source activation, and/or the sensor measurement parameters. An additional scanning delivery unit may be operably coupled to the controller or to the sensors to provide a controlled distribution of electromagnetic energy to the target region of the skin. The use of positional measurement sensors and dosage evaluation sensors permits the controller to automatically determine the proper electromagnetic source parameters including, for example, pulse timing and pulse frequency.

Method and apparatus for monitoring and controlling thermally induced tissue treatment

A method of reducing wrinkles in skin includes irradiating the skin with laser pulses to ablate an array of spaced apart voids in the skin. A region of coagulated tissue surrounds each of the voids and there viable tissue between the coagulated regions. Tissue in the coagulated regions is in tension due to shrinkage of collagen by the heat generated during the ablation. This tension rapidly closes the voids, tightening the skin and reducing the wrinkles. A healing process replaces the coagulated tissue with new tissue after a period of about one-month. The method is also applicable to lightening abnormally pigmented skin, as the new tissue replacing the coagulated tissue is not abnromally pigmented.

Laser System for Treatment of Skin Laxity

An imaging sensor forms an image of at least a portion of a moving element that moves relative to a dermatological treatment handpiece in response to motion of the handpiece across the skin. A processor uses multiple images from the imaging sensor to determine changes in position or velocity of the moving element. The treatment energy source is adjusted or triggered in response to the calculation. Image relaying optics may be used to remotely position the imaging sensor away from the handpiece.
