摘要:
Surgical clips, which are particularly useful in the transoral invagination and fundoplication of the stomach to the esophagus, are disclosed. The clips include first and second arms joined by a bridge to form a substantially U-shape. The arms are provided with a first structure adapted to prevent a movement of the clip in a direction perpendicular to a longitudinal axis of the clip after the clip is applied to tissue. In addition, the clips preferably also include a second structure adapted to prevent rotation of the clip about the longitudinal axis of the clip after the clip is applied to tissue.

Surgical clips, which are particularly useful in the transoral invagination and fundoplication of the stomach to the esophagus, and methods of applying the surgical clips to living tissue are disclosed. The clips include first and second arms joined by a bridge to form a substantially U-shape, and which are provided with a first structure adapted to prevent a movement of the clip in a direction perpendicular to a longitudinal axis of the clip after the clip is applied to tissue. In addition, the clips preferably also include a second structure adapted to prevent rotation of the clip about the longitudinal axis of the clip after the clip is applied to tissue.
摘要:
A retrofitting, inductive-battery-charging device for use with a surgical sterilization device, comprising an inductive charging assembly and an inductively powered battery-charging platform that is sterilizable inside a surgical sterilization device and is operable to charge at least one rechargeable battery of a battery-operated surgical instrument when the rechargeable battery is placed at the platform. The inductive charging assembly comprises an inductive-power-supply sub-assembly electrically connected to a power supply and is operable to supply power inductively over a distance at least equal to a width of a wall of the surgical sterilization device, and an inductive-power-receiver sub-assembly that is sterilizable inside the surgical sterilization device and electrically coupled to the platform. The inductive-power-receiver sub-assembly is operable to supply charging power to the platform for charging the at least one rechargeable battery when placed at the platform, and to inductively receive electrical power from the inductive-power-supply sub-assembly at least over the distance.
摘要:
A method for simultaneously surgically sterilizing and charging a battery, which comprises providing an inductively powered battery charger inside a selectively sealable surgical sterilization enclosure of a surgical sterilization device. The surgical sterilization device is operable to surgically sterilize at least one rechargeable battery of a battery-operated surgical instrument placed therewithin. The charger has an inductive power receiver sub-assembly operable to receive power inductively and to supply charging power to the at least one rechargeable battery. The at least one rechargeable battery is electrically charged while being surgically sterilized by supplying power inductively from a power supply positioned outside the surgical sterilization enclosure to the inductive power receiver sub-assembly through the surgical sterilization enclosure.
摘要:
A device for sterilizing and charging a battery of a surgical instrument, comprising a surgical sterilization device that has a sealable sterilization enclosure and is operable to surgically sterilize a rechargeable battery of a battery-operated surgical instrument when the battery is sealed in the sterilization enclosure. An inductively powered battery-charging platform is also disposed inside the sterilization enclosure and has a charger that conductively charges the battery when the battery is placed at the charger. A power receiver sub-assembly that is electrically coupled to the charger receives electrical power inductively from a power supply that is disposed outside the sterilization enclosure. Thus, the battery is charged without breaching the sealed sterilization enclosure and simultaneously while the battery is being sterilized.
摘要:
A method of configuring a surgical instrument having a surgical tissue-compressing device including opposing compression surfaces with a tissue-compression-measuring mechanism, the method comprising providing a switching element having first and second switching states changed solely by mechanical movements, mechanically coupling the switching element with a biasing element retaining the switching element in one of the first and second switching states until a pre-determined force is imparted to the switching element, the pre-determined force being an amount of force proportional to an optimal tissue compression force of compressed tissue disposed between the opposing compression surfaces, and positioning the switching element in line with the surgical tissue-compressing device to cause the pre-determined force, proportional to a force placed upon compressed tissue disposed between the opposing compression surfaces, to be placed upon the switching element.
摘要:
A method for creating a sealed device includes the steps of providing a structure comprised of at least two adjacent parts forming an enclosure and having a contact surface therebetween. At least one part of the structure is comprised of a material that appears substantially opaque to the naked eye and is substantially transparent to light. A light-curable adhesive is applied at the contact surface, and light is transmitted to cure the light-curable adhesive to form a hermetic seal at the contact surface between the at least two adjacent parts.
摘要:
A battery assembly for use with a surgical device having a battery terminal and operational parameters includes a housing having a shape formed to removably connect with the terminal. The housing contains a modular battery operable to supply power to the device at the terminal and has a control circuit with a microprocessor, a memory, and a real-time clock. The control circuit is communicatively coupled to the battery and is operable to detect an identity of the surgical device, to determine at least one piece of information pertaining to at least one of the operational parameters of the surgical device based upon the detected identity, to record the piece of information at least in the memory, and to selectively allow or prevent the battery from supplying power to the surgical device dependent upon the piece of information.
摘要:
A surgical instrument includes a surgical end effector operable to effect a surgical procedure when powered, an electric motor operationally connected to the end effector, and a power supply electrically connected to and selectively powering the motor to operate the end effector, the power supply having at least one battery cell with a critical current rate and having a switch that when activated to power the motor, operates the at least one battery cell at a super-critical current rate.

A method for powering electrically powered surgical instruments includes removably inserting a cordless battery assembly into a handle thereof, the instrument handles having a battery chamber and different types. The battery assembly comprises an energy cell powering a signal generation assembly of the instruments. A battery/handle interface has connectors mating with connectors within the chamber. A voltage-control circuit is operable to communicate with and power the signal generation assembly, detect which handle type is connected to the battery assembly, and provide different outputs in response to a detection of the handle types. As the battery assembly is inserted, connectors of the battery/handle interface are coupled with connectors within the battery chamber to communicatively couple the voltage-control circuit to the signal generation assembly and provide power thereto. The connected handle is detected and dependent upon the detected handle type a different one of the outputs are provided.
