SUMMARY OF THE INVENTION: the device comprises a osseous rod in the form of a hollow needle 1 with a groove 5 in the middle portion communicating with the cavity. A flange 3 with holes 4 for fastening to the skin is made on the supply end of the needle, and a bent pointed tip is provided on the fastening end. Fixing elements made in the form of a flexible thread are connected with a needle. 2 C.p. f-ly, 3 ill.

Description

Изобретение относитс к медицине, в частности к проведению накостного остео- синтеза переломов нижней челюсти, преимущественно по углу.The invention relates to medicine, in particular to performing osteosynthesis of lower jaw fractures, mainly in angle.

Известно устройство дл остеосинтеза, например спица, содержаща канюлю с продольным каналом и сообщающимис с ним поперечными боковыми отверсти ми. j Недостатком этъго устройства вл етс то, что оно не обеспечивает проведение закрепл ющих элементов и надежной фикса- ции:устр6йства.Известно также устройство дл остеосинтеза , например спица, содержаща канюлю с продольным осевым каналом, сообщающимс с боковым отверстием и планкой дл оро- . шени тканей лекарственными веществами по всей рабочей длине спицы.A device for osteosynthesis is known, for example a spoke, comprising a cannula with a longitudinal channel and transverse lateral openings communicating with it. j The disadvantage of this device is that it does not provide fastening elements and secure fixation: devices. An osteosynthesis device is also known, for example a spoke, comprising a cannula with a longitudinal axial channel communicating with a lateral opening and an oro bar. tissue tissues with medicinal substances along the entire working length of the knitting needle.

Недостатки те же, что и-у предыдущего аналога.The disadvantages are the same as the previous analogue.

Известно также устройство дл остеосинтеза , содержащее накостный стержень с элементами подвода лекарственных веществ и элементы фиксации, св занные со стержнем. . . A device for osteosynthesis is also known, comprising a osseous rod with drug delivery elements and fixation elements associated with the rod. . .

Недостатком устройства, прин того за прототип, вл етс невозможность проведени диализа.A disadvantage of the device adopted for the prototype is that dialysis is not possible.

Цель изобретени - обеспечение возможности проведени диализа.The purpose of the invention is to enable dialysis.

Указанна цель достигаетс тем, что канюлю на игле располагают с возможностью проведени закрепл ющего элемента. Ка- : июл имеет фланец с отверсти ми дл фиксации устройства на коже, а острый конец иглы, выполнен с возможностью разгибани образованного под пр мым углом выступа в процессе ее. удалени .This goal is achieved in that the cannula on the needle is positioned to hold the fastening element. Ka-: July has a flange with holes for fixing the device to the skin, and the sharp end of the needle is configured to extend the protrusion formed at a right angle during it. removal.

На фиг. 1 изображено устройство, общий вид с продольным разрезом на момент укладки; на фиг. 2 - вид на фланец (разрез А-А); на фиг, 3 - схема закреплени на кости.In FIG. 1 shows a device, a General view with a longitudinal section at the time of installation; in FIG. 2 is a view of the flange (section AA); Fig. 3 is a diagram of a bone anchorage.

На фигурах прин ты следующие обозначени : The following symbols are used in the figures:

Claims

1 - Needle; 2 - cannula; 3 - flange: 4 - holes for stitching the device to the skin ;. 5 - groove in the body of the needle for supplying the drug; b

- a hole for supplying medication ;. 7 - a fixing protrusion; 8 - holes in the bone

for holding the bonding material; 9

- a hole in the bone for laying the protrusion 7; 10 - fastening material (kapron thread, steel wire ...); 11 node; 12-line

fracture; 13 shows a furrow for laying a needle 1.. The device is used as follows.

After creating operational access to the fracture site and compiling it, it is fragmented.

correct position, a groove 13 is made on the bone through the fragments to place the needle 1 in it so that it lies preferably perpendicular to the fracture line. Step back 1-1.5 cm from

fracture lines 12 open holes 8 on both sides for the passage of the bonding material 10.

Then a flap is formed 0.5-1.0 cm from the hole for the fixing protrusion 7. Soft tissue is cleaved to fit the needle into the prepared bed, bending the end of the needle in the wound and thereby creating the fixing protrusion. A two-fold fastening material is inserted through the hole 8, the free ends of which are guided through the other hole 8, around the fracture site, the needle is laid, a knot of the held material is bound, one end of which cuts off, and the other is pushed into the groove and

output through cannula. The reliability of osteosynghesis, the ability to deliver medication are checked. Treatment is carried out, at the end of which the device is removed with simultaneous extension of the needle tip due to the interaction of the fixing end of the needle 7 and the front wall of the pit 9, after which the fastening material is removed, since it is freed from interaction with the needle.

. .,.,. :

F about r. 1. The device for a bone osteosynthesis comprising a bone rod with elements for supplying drugs and fixation elements associated with the rod, characterized in that, in order to enable dialysis, the rod with elements for delivering drugs in the form of a hollow needle with a slot in the middle section communicating with the needle cavity, flange

holes for fixing to the skin on the inlet end and a bent pointed tip on the mounting end, and the fixing elements are made in the form of a flexible thread.

2. The device according to claim 1, with the exception that the supply end of the needle is bent with a radius equal to 10-15 diameters of the needle,

3. The device according to claim 1, with the exception that the length of the tip is equal to 1.0-1.5 diameter of the needle.
