Title: Innovations by Ronald R Van Overloop
Introduction
Ronald R Van Overloop is a notable inventor based in West Chester, OH (US). He has made significant contributions to the field of surgical stapling devices, holding 2 patents that showcase his innovative approach to medical technology.
Latest Patents
One of his latest patents is the "Pneumatically actuated linear stapling device." This pneumatic stapler features a mechanism for manual or automatic retaining pin placement. The automatic retaining pin is connected to a set of linkage plates that are actuated by a series of inflation of bladders. This design allows for instrument closure on tissue compression while simultaneously creating pin placement. An optional manual, curved retaining pin can be used in place of the automatic pin system. The instrument also includes a ramped anvil mechanism that provides adjustable staple height. Controlled closure is achieved with a detent spring and constant force springs. Upon stapling, the staple encounters a reduced-size anvil, which is kept closed by a latched retaining pin system, enhancing the versatility of the stapling head. After firing the staples, the mechanism allows for rapid depressurization and simultaneous instrument opening through a spring return mechanism. A shaft connects the head to the handle, allowing for rotation and articulation in a universal joint or in two discrete locations, both equipped with a locking system for angle selection during insertion.
Another significant patent is the "Bladder and mandrel for use with surgical stapler." This invention presents a disposable mandrel and bladder, where the mandrel is either injection molded or machine fabricated to be permanently incorporated within the driver bladder of a surgical stapling mechanism. The supply line tubing is an integral part of the mandrel, ensuring it is permanently bonded to the bladder sub-assembly. This configuration prevents tube clogging and bladder folding over infusion lines, resulting in reliable firing of the stapler while utilizing a pneumatic driving mechanism.
