Изобретение относитс  к медицинской технике .The invention relates to medical technology.

Известно устройство дл  биопсии, содержащее корнус, пистолетную руко тку, иглу, толкатель ножа.A device for biopsy is known, comprising a cornus, a pistol grip, a needle, a knife pusher.

Цель изобретени  - удержание срезанной ткани в полости устройства.The purpose of the invention is to keep cut tissue in the cavity of the device.

Это достигаетс  тем, что в корпусе устройства выполнены цилиндрические полости, в которых размещены поршень со штоком и приводом.This is achieved by the fact that cylindrical cavities are made in the housing of the device, in which a piston with a rod and a drive is placed.

На чертеже изображено предлагаемое устройство , общий вид.The drawing shows the proposed device, a General view.

Устройство содержит корпус 1 с пистолетной руко ткой 2 и цилиндрической полостью 3, в которой расположен порщень 4 со щтоком 5.The device comprises a housing 1 with a pistol grip 2 and a cylindrical cavity 3 in which the piston 4 with the brush 5 is located.

Поршень выполнен за одно целое с толкателем 6 ножа. Устройство содержит рабочий привод, выполненный в виде кнопки 7 и пружины 8. Привод соединен с толкателем 6 ножа . В корпусе расположены перепускной капал 9 и отверстие 10 дл  ликвидации вакуума . Цилиндрическа  полость закрыта крышкой 11. В поршне 4 находитс  отверстие, перекрываемое клапаном 12.The piston is made in one piece with the pusher 6 knife. The device contains a working drive, made in the form of a button 7 and a spring 8. The drive is connected to the pusher 6 of the knife. In the housing there are an overflow drip 9 and a hole 10 to eliminate the vacuum. The cylindrical cavity is closed by a cover 11. In the piston 4 there is an opening blocked by a valve 12.

Отсекающий нож 13 расположен внутри сменной иглы 14 и крепитс  на толкателе ножа с помощью резьбового соединени . Игла 14 устанавливаетс  на конус в корпусе 1 и фиксируетс  гайкой-ограничителем 15 глубины укола. Игла 14 имеет прорезь дл  забора ткани. Совпадение лезви  ножа 13 с прорезью иглы фиксируетс  гайкой 16.The cut-off knife 13 is located inside the replaceable needle 14 and is attached to the knife pusher by means of a threaded connection. The needle 14 is mounted on a cone in the housing 1 and fixed with a nut-limiter 15 of the injection depth. The needle 14 has a slot for collecting tissue. The coincidence of the blade of the knife 13 with the needle slot is fixed by the nut 16.

Устройство дл  биопсии работает следуюи им образом.The biopsy device works in the following way.

В зависимости от конкретных условий биопсии выбираютс  по длине и диаметру нож 13 и сменна  игла 14, устанавливаютс  в устройство , фиксиру сь гайкой-ограничителем 15Depending on the specific conditions of the biopsy, the knife 13 and the interchangeable needle 14 are selected along the length and diameter, and are installed in the device, fixed with a nut-stop 15

глубины укола. Инструмент берут в правую руку за пистолетную руко тку 2, толкатель ножа приводитс  в движение нажатием большим пальцем на кнопку 7. В этом момент отсекающий нож 13 полностью закрывает прорезь иглы 14. В таком состо нии игла вводитс  в исследуемый орган до упора гайки-ограничител  15. Отпустив кнопку 7, под действием пружины 8 открываетс  прорезь иглы 14 и заполн етс  тканью исследуемого органа.depth of injection The tool is taken into the right hand by the pistol grip 2, the knife pusher is set in motion by pressing the button 7 with your thumb. At this point, the cutting knife 13 completely closes the slot of the needle 14. In this state, the needle is inserted into the test body until the stop nut 15 is locked Releasing the button 7, under the action of the spring 8, the slot of the needle 14 opens and is filled with the tissue of the test organ.

Вторичным нажатием большого пальца на кнопку производитс  отсечение кусочка ткани , нахЧод щегос  в прорези иглы. При этом поршень 4 при движении вперед создает позади себ  вакуум, который через перепускнойA second pressing of the thumb on the button produces a clipping of a piece of fabric, which is located in the needle slot. At the same time, the piston 4, when moving forward, creates a vacuum behind itself, which, through the overflow

канал 9 распростран етс  на полость иглы иchannel 9 extends into the needle cavity and

надежно удерживает срезаемую ткань. В момент окончанн  среза вакуум ликвидируетс  через отверстие 10. Продолжа  удерживать кнопку в нажатом состо нии, устройство извлекаетс  из органа. Клапан 12 служит дл  избежани  нагнетани  воздуха в полость иглы при обратном ходе поршн . Привод устройства расположен в цилиндрической полости 17.reliably holds the cut-off fabric. At the time of the cut-off, the vacuum is eliminated through the opening 10. Continuing to hold the button in the depressed state, the device is removed from the organ. The valve 12 serves to avoid the injection of air into the needle cavity during the return stroke of the piston. The drive device is located in the cylindrical cavity 17.
