A holding device for holding and supporting at least one medical instrument, more specifically a surgical handpiece. The holding device includes a central feedline, at least one line portion of which is connected to the end portion of a central feedline. At least one surgical handpiece can be coupled to the line portion. The holding device also includes a connector portion formed on another end portion of the central feedline. The connector portion can be coupled to a preliminary cleaning unit, more specifically a water/compressed air gun, and a cleaning unit, more specifically a filter unit connected to a rinsing line.

A tissue resecting device includes a housing having an outer shaft, the outer shaft including a tool portion disposed at a distal end thereof having a window defined therein with a proximal cutting edge. An inner shaft is disposed within the outer shaft and includes proximal and distal ends, the inner shaft configured to rotate upon actuation thereof. A cork-screw member extends distally from the distal end of the inner shaft and into the window. The cork-screw member is configured to rotate concomitantly with the inner shaft and includes a barb at a distal end thereof configured to pierce and retain tissue thereon. Upon rotation of the inner shaft, the barb pierces and retains tissue and withdraws tissue proximally along the cork-screw member and into the outer shaft and wherein excess tissue is excised by the proximal cutting edge of the window as the tissue is withdrawn through the outer shaft.

A tissue guard for use with a surgical access device includes a proximal ring having proximal and distal ends, the distal end configured to operably couple to a ground ring that ultimately electrically connects to an electrical ground. One or more mechanical interfaces extend about the proximal ring and are configured to mechanically engage a rim of an access device to secure the tissue guard thereon. A retention body is configured to operably couple to a distal end of the ground ring, the retention body including a distal end configured to operably engage the access device to secure the tissue guard therein.

A reload assembly includes a shell housing, a knife carrier, and at least one engagement member. The shell housing includes an inner housing portion and an outer housing portion that is spaced from the inner housing portion to define an annular cavity. A catch is supported within the annular cavity. The knife carrier defines a longitudinal axis and supports a knife. The knife carrier also supports a resilient locking member that is positioned to engage the catch when the knife carrier is in its retracted position after the reload assembly has been fired to retain the knife carrier in the retracted position.

Percutaneous gas diffusion device. In one embodiment, the percutaneous gas diffusion device includes a core layer, an outer layer, and an intermediate layer. The core layer may be cylindrical and may include a gas-permeable, liquid-impermeable material. The outer layer may peripherally surround the core layer and may include a tissue-integrating material. The intermediate layer may peripherally surround the core layer and may be peripherally surrounded by the outer layer. The intermediate layer may include a barrier that prevents infiltration of tissue from the outer layer into the core layer and that additionally reduces diffusion of gas from the core layer into the outer layer. The percutaneous gas diffusion device may be coupled to a subcutaneous implant device, such as a subcutaneous container holding implanted cells and/or tissue, a subcutaneous electrochemical oxygen concentrator, or a water electrolyzer.

A surgical pump assembly includes a motor configured to provide a motor output, a transmission assembly configured to receive the motor output and provide a plurality of transmission outputs, and a plurality of pumps. Each pump of the plurality of pumps is configured to receive one of the transmission outputs of the plurality of transmission outputs. A surgical generator includes at least one energy module configured to generate an energy-delivery signal, at least one energy port configured to connect to a surgical instrument to deliver the energy-delivery signal thereto, and the surgical pump assembly.

A medical device is provided comprising a first port; a second port in fluid communication with the first port; and a third port in selective fluid communication with both the first port and the second port; a sealing membrane disposed between the third port and both the first port and the second port, the sealing membrane is configured to move between a first position preventing fluid communication between the third port and both the first port and the second port and a second position allowing fluid communication between the third port and the first port, wherein movement of a fluid supplied to the medical device at the third port moves the sealing membrane from the first position to the second position.

Various cartridge assemblies for surgical instruments are provided. Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element. Cartridge assemblies can also include physical features and/or stored data that identify the cartridge. Surgical instruments further can be configured to resolve conflicts when the physical features and/or stored data are not consistent with each other in their identification of the cartridge type.

The Vertebra Pick Device represents a new instrument to bore pilot holes in vertebra pedicles while imaging the operation with an integrated endoscope. The pilot holes are bored to provide entry points for pedicle screws that serve as anchor points for spine stabilizing rods to treat several spine conditions. The device consists of a metal body that terminates in a tapered incision tip, an endoscope that runs inside said metal body, a handle to drive the device into pedicle boney tissue and a fiber optics bundle assembly that enters the device handle and is used to connect to imaging, illumination, irrigation and suction devices to enable the endoscopic functions of the device. The fiber optics bundle assembly connects to an imaging camera that provides an electrical signal to a monitor to view the operation in real time.

A collector used to collect bone includes: a container body defining an interior containment space for receiving and retaining collected bone, and having at least one open end for access and removal of collected bone from the interior containment space; and a cap in covering relation to the open end of the container body such that access to the interior containment space for removal of collected bone is inhibited. The collector includes an intake port defining an opening for receiving therein a distal end of a kerrison rongeur for collecting cut bone from a cutting area thereof, and the cap includes at least one scraper for engaging and dislodging cut bone from the cutting area of a distal end of a kerrison rongeur when received within the intake port. The collector preferably is used with a kerrison-type rongeur for collecting cut bone therefrom.
