Description

Изобретение относитс к медицинской технике, а именно к устройствам дл биопсии . The invention relates to medical engineering, in particular to devices for biopsies.

Известно устройство дл биопсии, содержащее корпус с электроприводом и с рабочим органом, снабженным полой режущей иглой, имеюи.ей возможность вращательно-поступательного движени 1. A device for biopsies comprising a housing with electric drive and with a working member provided with a hollow cutting tip, the possibility imeyui.ey rotary translational movement 1.

Однако это устройство не позвол ет получить качественный биоптат с высокой гистотопографической информативностью. However, this device does not allow to obtain high-quality biopsy gistotopograficheskoy informative.

Целью изобретени вл етс повыщение гистотопографической информативности биоптата и повышение атравматичности. The aim of the invention is the Enhance gistotopograficheskoy informative noninvasive biopsy and improvement.

Указанна цель достигаетс тем, что рабочий орган устройства выполнен в виде полого наконечника с пружин щими раздвижными лепестками, внутри которого расположена режуща игла, с возможностью возвратно-поступательного движени относительно наконечника. Said object is achieved in that the operating device body is configured as a hollow tip with a conductive sliding springs petals, inside which is located a cutting needle with reciprocating motion relative to the handpiece. Кроме того, рабочий конец режущей иглы на внутренней поверхности снабжен нарезкой, а дл получени биоптата из полых органов устройство снабжено сменным изогнутым наконечником, в котором режуща игла св зана с электроприводом гибким тросом. Moreover, the working end of the cutting needle is provided on the inner surface of the thread and for producing hollow bodies from biopsy device is provided with a removable curved tip, wherein the cutting needle is bonded to a flexible electric cable.

На фиг. FIG. 1 изображено устройство дл биопсии, вертикальный разрез; 1 shows the biopsy apparatus of a vertical section; на фиг. FIG. 2 - рабочий орган, продольный разрез; 2 - working member, a longitudinal section; на фиг. FIG. 3сменный изогнутый наконечник. 3smenny curved tip.

Устройство дл биопсии имеет корпус 1, к которому присоедин етс полый наконечник 2 с пружин щими раздвижными лепестками 3 на рабочем конце. Biopsy apparatus has a housing 1 to which is attached a hollow tip 2 with conductive sliding springs 3 petals at the tip end. Внутри наконечника 2 размещена пола режуща игла 4 с винтовой нарезкой 5 ha внутренней поверхности рабочего конца, котора другим концом сопр жена с валом размещенного в корпусе 1 электродвигател 6 посредством втулки 7. Последн щарниром 8 сопр жена с подпружиненным рычагом-курком 9, который щарнирно закреплен на корпусе 1 и взаимодействует с микровыключате,пем 10 электродвигател 6 . Inside the floor nozzle 2 is placed cutting needle 4 with a screw thread 5 ha inner surface of the working end of which the other end mates with a shaft placed in the casing 1 of the motor 6 by means of the sleeve 7. The latter scharnirom 8 mates with a spring-loaded trigger lever-9 which is fixed scharnirno on the housing 1 and communicates with mikrovyklyuchate, letters motor 10 6.

Устройство снабжено также сменным изогнутым наконечником 11, в котором размещена пола режуща игла 4, соединенна гибким валом 12 со стержнем 13, присоедин емым к втулке 7, сопр женной с валом электродвигател 6. The apparatus is also provided with a removable curved tip 11, which accommodates the cutting cannula 4, connecting flexible shaft 12 to the rod 13, attached to the hub emym 7, mating with a shaft of the motor 6.

Устройство работает следующим образом. The apparatus operates as follows.

Нажимом на рычаг-курок 9 сопр женна с ним щарниром 8 втулка 7 перемещаетс Pressure on the trigger lever 9, conjugated to it scharnirom 8 bush 7 is moved
