(54) СПИЦЕНАТЯГИВАТЕЛЬ(54) SPITNESSER

1one

Изобретение относитс к медицинской технике, а именно к устройства.м дл осуществлени остеосинтеза.The invention relates to medical technology, namely to an apparatus for performing osteosynthesis.

Известен спиценат гиватель, содержащий корпус, в котором установлен толкатель с резьбовым концом и руко ткой и спица с гайкой 1.A known spicate gavatel, comprising a housing in which a pusher with a threaded end and a handle and a needle with a nut 1 is installed.

Однако известный спиценат гиватель требует наличи об зательного отверсти в дуге дл установки в нем толкател . При этом отверстие в спицедержателе определ ет направление нат гивани спицы, которое не может быть выбрано произвольно. Таки.м образом, конструкци известного спиценат гивател не позвол ет использовать его автономно с устройством дл лечени переломов костей, что ограничивает область его использовани .However, the known spicate givatel requires the presence of a mandatory hole in the arc for mounting the pusher in it. At the same time, the hole in the cutter holder determines the direction of tension of the needle, which cannot be chosen arbitrarily. In this way, the design of a known sphivatum does not allow its use autonomously with a device for treating bone fractures, which limits its use.

Целью изобретени вл етс возможность автономного использовани спиценат гивател с устройствами дл лечени переломов костей.The aim of the invention is the possibility of autonomous use of givatel spiaticate with devices for the treatment of bone fractures.

Указанна цель достигаетс тем, что спиценат гиватель, содержащий корпус, в котором установлен толкатель с резьбовым концом и руко ткой и спица с гайкой, снабжен упором, который выполнен в виде Г-образного кронштейна, один конец которого установлен в корпусе с возможностью перемещени в не.м, а второй конец имеет отверстие под спицу и контактирует с толкателем .This goal is achieved in that the spacifier, comprising a body in which a pusher with a threaded end and a handle and a needle with a nut is installed, is provided with an abutment, which is made in the form of an L-shaped bracket, one end of which is mounted in the body m, and the other end has a hole for the needle and is in contact with the pusher.

вид спереди с частичным сечением; на фиг. 2сечение А-А на фиг. 1.front view with partial section; in fig. 2 section A-A in FIG. one.

Спиценат гиватель содержит корпус 1, выполненный в виде пластины с руко ткойThe power gauge contains a body 1, made in the form of a plate with a handle

,Q в виде Г-образного кронштейна, и упор 2, толкатель 3 с резьбовым концом и руко ткой. Корпус 1 снабжен резьбовым хвостовиком 4, пр моугольным отверстием 5 дл установки в свободной посадке упора 2, резьбовым отверстием 6 дл установки в нем, Q in the form of an L-shaped bracket, and an emphasis 2, a pusher 3 with a threaded end and a handle. The housing 1 is provided with a threaded shank 4, a rectangular hole 5 for installation in the free fit of the stop 2, a threaded hole 6 for installation in it

5 толкател 3 и отверстием 7 у основани резьбового хвостовика 4 дл фиксации в нем гайкой 8 с рифленой шайбой 9 нат гиваемой спицы 10.5 pusher 3 and a hole 7 at the base of the threaded shank 4 for fixing therein a nut 8 with a corrugated washer 9 of the knitting needle 10.

Спиценат гиватель используют следую20 щим образом.The gauze package is used in the following way.

Claims

Put the spicate givatel on the gripping end of the needle 10 until it stops in the retainer clamp -11 (Fig. 1) and fix this needle in the hole 7 with a nut with a corrugated washer 9. Screw the threaded end of the pusher 3 into the hole 6 of the housing 1 to perform the spoke traction to a predetermined degree her tension in the spitcher. To remove the givatel spicate, it is enough to loosen the nut 8 on the threaded shank 4, after which the gripping end of the spoke goes free from the coaxial holes of the body 1 and the stop

2. The advantage of the proposed sphivatum is its versatility, i.e., the possibility of using it in any known device for treating bone fractures, achieved by the fact that the emphasis of the sphivatt givatel is L-shaped and mounted in the housing with the ability to move the spokes by contacting with him a threaded pusher. The dimensions of the part of the stop 2 which is in contact with the cutter holder do not extend beyond the latch 11, which makes it possible to use the spice holder for any cadre of the cutter holder and even for direct connection to any part of the device for medical treatment of the bones. The simplicity of the design of the givatel spicate provides ease of use and operational reliability. Claims The invention includes a housing in which a pusher with a threaded end and a handle is installed and a needle with a nut, characterized in that, in order to allow autonomous use of the spicant with a device for treating fractures of bones, the tongue is equipped with an abutment. which is made in the form of an L-shaped bracket, one end of which is mounted in the housing with the possibility of moving in it, and the other end has an opening under the needle and is in contact with the pusher, Sources of information taken into account during the examination 1.
