Embodiment Construction

[0023] The present invention provides a holder for an (external) object (300), which in a particular embodiment is a cannula or trocar for a minimally invasive surgical procedure, said holder having two member. figure 1 is a schematic diagram of one embodiment of a retainer. In this embodiment, the retainer itself need not have a distant center of motion, so when it is to be used in a minimally invasive surgical procedure, it must be combined with another object (300), which in one particular embodiment is A cannula or trocar that moves around the distal center of motion (the patient's incision) (8). The instrument holder of the present application may be used in minimally invasive surgical procedures selected from video-assisted thoracoscopic surgery, laparoscopic surgery, and arthroscopic surgery; especially laparoscopic surgery. In this above-described embodiment, the center of distant motion coincides with the incision on the patient's abdomen. Not limited to laparoscop...

Abstract

The invention relates to a retainer which must be combined with an external body whereby the external body moves around a distant center of motion. The external object is preferably a medical instrument such as a cannula or trocar, whereby the center of distant motion is the patient's abdomen. The holder consists of two components that generate movement longitudinally and rotationally. The holder can be used to support another object, which in a particular embodiment is a video camera, facilitates endoscopic (laparoscopic) surgery and is equipped to generate motion along XYZ coordinates in a longitudinal and rotational manner . The holder of the invention is especially useful for working in small areas, since it occupies only a small bedside space and does not scratch the functional working area of ​​the instrument mounted on the holder.

Description

technical field [0001] The present invention relates to a holder which must be combined with an external body whereby the external body moves around a distant center of motion. The external object is preferably a medical instrument, such as a cannula or a trocar, whereby the center of distant motion is an incision in the patient's abdomen. The holder may be used to support another object, and in a particular embodiment a video camera, to facilitate endoscopic procedures, including video-assisted thoracoscopic, laparoscopic and arthroscopic procedures; the holder The device is equipped with facilities for generating motion in longitudinal direction and in rotation along XYZ coordinates. The holder of the invention is especially useful for working in small areas, since it occupies only a small bedside space and does not scratch the functional working area of ​​the instrument mounted on the holder. Background technique [0002] In standard laparoscopic surgery, an incision is...
