Biomedical engineering (BME) or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare purposes (e.g. diagnostic or therapeutic). This field seeks to close the gap between engineering and medicine, combining the design and problem solving skills of engineering with medical biological sciences to advance health care treatment, including diagnosis, monitoring, and therapy. Also included under the scope of a biomedical engineer is the management of current medical equipment within hospitals while adhering to relevant industry standards. This involves equipment recommendations, procurement, routine testing and preventative maintenance, through to decommissioning and disposal. This role is also known as a Biomedical Equipment Technician (BMET) or clinical engineering.

Surgical stapler anvil with nested staple forming pockets

InactiveUS6953138B1Increased lateral widthLittle lateral spaceSuture equipmentsStapling toolsMirror imageBiomedical engineering
A surgical stapler anvil provides an expanded leg-receiving target area for a staple forming pocket in a compact staggered array by narrowing the lateral width of the leg-clinching portion of a laterally adjacent pocket. Advantageously, the lateral spacing between adjacent rows of staple forming pockets can remain small, while the leg-receiving target area for laterally adjacent rows of pockets is significantly expanded. The staple forming pockets include two mirror image leg-forming cups. The cups are longitudinally aligned with their respective ascending leg clinching portions adjoining in the center of the pocket. Laterally spaced guide surfaces extend upwardly and outwardly from the clinching surface at the bottom of the cup to define an expanded leg-receiving target area at the distal ends of the pocket. Substantially planar laterally outward portions of the guide surface intersect with the guide surface of a laterally adjacent pocket to form a non-linear ridge.

Powered surgical stapling device

A surgical stapler which includes a tool assembly having a pair of opposing tissue engaging surfaces for deforming a plurality of surgical fasteners through and fastening tissue is disclosed. The surgical stapler includes a housing having a fixed handle and a movable handle mounted to the housing and selectively movable relative to the fixed handle from a first position to a second position to actuate the clamping of tissue. The stapler further includes a drive assembly including a motor, a power source and a coupling member. The motor engages the coupling member, wherein movement of the movable handle to the second position activates the motor, which advances a firing shaft and forces a firing piston into the tool assembly to deform the surgical fasteners through and fasten tissue.

Disposable loading units for a surgical cutting and stapling instrument

In various embodiments, a disposable loading unit for a surgical stapling instrument can include an anvil, a staple cartridge, a staple cartridge channel for operably supporting the staple cartridge, and a connector for removably attaching the disposable loading unit to the surgical instrument. In at least one embodiment, a first staple cartridge can be replaced with another staple cartridge after the first staple cartridge has been at least partially expended. In various embodiments, a staple cartridge can include a staple driver for deploying staples from the staple cartridge and a cutting member for incising tissue, wherein a new staple driver and a new cutting member can be provided with each new staple cartridge. The anvil can be removably attachable to the disposable loading unit such that a new anvil can be utilized with a new staple cartridge.

Anastomosis device

The present invention is directed to a circular anastomosis surgical stapler and methods of use. The circular anastomosis surgical stapler includes an operator control assembly, a tubular shaft having a distal end that is associated with a head portion, and an actuating head portion. The actuating head portion includes a detachable anvil portion with an axially extending stem portion. The anvil portion is engagable with the remainder of the head portion, which receives an array of staples. The head portion also includes an associated stapling portion with a stapling mechanism for firing an array of staples against the anvil portion. The anvil portion and the head portion matingly engage along a mating edge. The mating edge is defined by locations around the stem portion spaced from a particular position on the axis of the stem portion at axially and / or radially varying distances.
