摘要：
The utility model refers to medicine, namely to devices for positioning medical instruments during surgery, for example, regular bone biopsy needles of 12G or more, cluster electrodes of RF-ablation Cool-Tip, endoscopes and trocars, etc. The holder includes arcuate brackets with guide grooves fixed on an annular base on the axes with the possibility of rotation in two mutually perpendicular vertical planes. The brackets in the window formed by the intersection of the guide grooves are connected by means of an annular clamp in the form of three coaxial sleeves connected by a thread. The inner and intermediate sleeves of the clamp have a shoulder in the lower part for placing the guides of the lower and upper brackets respectively on them. The inner sleeve is provided with a protruding part above the other two and is arranged to accommodate a trajectory pointer in the form of a detachable tube with a supporting flange providing an unobstructed passage of the medical instrument. In the areas of contact between the collars of the inner and intermediate sleeves and on the axes of fastening of the brackets are placed heat-resistant antifriction pads, for example, of the material ZEDEX®. The tractor pointer is adapted to be fixed to the inner sleeve of the clamp, for example by means of locks, a protrusion of the cavity.The technical result is an increase in the reliability of the device during the operation. 2 z.p. f-ly, 2 ill.Полезная модель относится к медицине, а именно к приспособлениям для позиционирования медицинского инструментария при оперативном вмешательстве, например штатные костные биопсийные иглы 12G и более, кластерные электроды радиочастотной аблации Cool-Tip, эндоскопы и троакары и т.д.
