The extension member defines a second axis and extends from the handle at approximately 90 thereby defining a plane. A bulbous (28, 228) or cylindrically shaped (128) blade located at the remote end of the extension member has its rounded surface (30, 32 or 130, 132 or 230, 232) extending out of the plane. By properly manipulating the handle, such as by rotating the same, the rounded surface of the blade is used to depress the sclera.

Methods and apparatus for delivering and positioning sheet-like materials in surgery

An implant delivery system for delivering a sheet-like implant is disclosed. The implant delivery system includes a distal guidewire port for receiving the proximal end of guidewire after the guidewire distal end has been affixed to a first point on bone or other tissue. The implant delivery system is tracked over the guidewire to a selected position defined by the guidewire attachment. The device includes an implant spreader assembly disposed proximate the distal end of a delivery shaft. The implant spreader assembly includes a first arm and a second arm. The arms are coupled to the delivery shaft such that the first arm and second arm are moveable between a closed position and an open position. When pivoting to the open position the distal end of each arm travels in a generally transverse direction to spread a sheet-like implant.

DIAMETER REGULATOR OF A DEVICE USED TO EXTRACT AN ELEMENT THAT IS INSIDE A CAVITY AND METHOD OF USE
20190029724 · 2019-01-31 · ·

A regulator diameter device to extract an element that is inside a cavity, which is introduced together with a flexible sleeve and an applicator, which comprises an adjustment strip of flexible material; and at least of a mean to regulate said diameter, with the adjustment strip open. The means to regulate such strip: a hollow case with a distal end and a proximal end, fixed to one of the traction handles, at least one string passes through this case, in which the distal ends of the at least one string, are fixed to the open ends of the adjustment strip, while the proximal ends of the string are fixed to a pulling system. The method of use of regulator diameter device to extract an element that is inside a cavity comprises the following steps: a. Introduce the combination (regulator device and the applicator) inside the cavity until the applicators' cup makes its first contact with the element to be extracted; b) go on pushing the combination which will open the distal ends of the applicator tentacles; c) once the mayor area of the element to be extracted is passed a first regulation of the adjustment strip is done, pulling the trigger and blocking it in this new position; d) keep on pushing until the final insertion; e) regulate again the adjustment strip until its final measure, being able to measure the diameter of the element to be extracted, which can be read in the pulling system scale; f) inflate the air chamber if the device has one; g) remove the applicator; h) pull the traction handles to extract the element that is inside the cavity.

MEDICAL INSTRUMENT FOR ABLATION OF TISSUE
20190015128 · 2019-01-17 ·

The present application discloses a medical instrument for tissue ablation by a minimally invasive surgical procedure, including a hollow outer shaft, an inner shaft which can be guided longitudinally displaceably in the hollow outer shaft, and a control portion at a proximal end of the medical instrument, in order to position the hollow outer shaft. An attachment for mechanical ablation of tissue is arranged at a distal end of the inner shaft, wherein the attachment does not protrude beyond an inner profile formed by the inner faces of the outer shaft, and wherein at any rate the distal end of the attachment protrudes beyond the distal end of the hollow outer shaft in order to ablate tissue. The medical instrument may be combined with further medical appliances, in particular with an HF coagulation attachment or a laser coagulation attachment for tissue coagulation.

Rigid elastic bent tool for laparoscopic surgery

A surgical tool and method of use during laparascopic surgery, the tool including a shaft having a distal region with an elastic modulus E. Distal and proximal regions of the shaft have outer diameters D.sub.1 and D.sub.2 respectively, with D.sub.2>D.sub.1. The distal region has a bend and terminates in a working feature having a distal end. The distal region has a length L1 measured in a direction parallel to the shaft axis in the proximal region, and has an offset d.sub.off relative to the proximal region where d.sub.off>D.sub.2. The elastic modulus E and the length of L1 are selected so that the working feature is insertable through an access device yet the distal region does not deflect noticeably when a force of 10 N is applied perpendicular to the distal end of the working feature.
