Benefits of technology

[0004]The present invention proposes overcoming the disadvantages of the prior art by proposing an insertion device which makes it possible to achieve the impaction of the insert into the cup with a very precise

Problems solved by technology

Insertion devices are already known that comprise a rod, an impaction head fixed to the end of the rod and designed to come into contact with the insert and gripping means designed for temporarily holding the insert to the insertion device when the impaction head is in contact with the insert, the latter being then adjusted by force to the cup by means of a shock or impaction applied to the rod by the surgeon to secure it in such a way that it is difficult, almost impossible, to remove.
Said devices of the prior art are complicated to use and do

Example

[0047]A first embodiment has been described above in which the surgeon applies the impaction shock by striking the rod.

[0048]It is possible, according to another advantageous embodiment, to provide at the proximal end of the rod 6 a part in the form of a pistol. Said part in the form of a pistol comprises a body 30 with a barrel 31 designed to be connected, in particular in a joined manner, to the rod 6. In the barrel 31 a cavity 32 is formed in which a plunger 33 is mounted to be movable in translation along the length of the axis of the barrel. A spring 34 is arranged at the rear of the plunger. A rod 36 joined to the plunger 33 passes through the spring and leaves the body 30 through a rear opening 50. The rod 36 enables the user, in particular by means of a ring 37 connected to the rod 36, to pull the plunger 33 to the rear thus compressing the spring 34 against a shoulder 51 of the plunger 33 until a transverse circular notch 38 is locked by clicking into an abutment 39. When t...

Abstract

Device for inserting an insert (1), made in particular of ceramic material, by impaction into a cup (50) designed to be received in the cotyl of a hip, comprising: means (17, 20, 21, 22) for gripping the insert, in particular at an upper free edge of the insert; a rod (5, 6) for the application of shock designed to be held by the surgeon and for the application of an impaction shock to the insert when it is held by the gripping means opposite the cup to be introduced therein; and an impaction head (9) with a surface designed to come in contact with at least one insert part, in particular the inner surface of a hollow of the insert.

Description

TECHNICAL FIELD[0001]The present invention relates to a device for inserting an insert element, made in particular of ceramic material, into a cup which is itself designed to be received in the cotyloidal cavity of a hip of a patient.BACKGROUND ART[0002]Insertion devices are already known that comprise a rod, an impaction head fixed to the end of the rod and designed to come into contact with the insert and gripping means designed for temporarily holding the insert to the insertion device when the impaction head is in contact with the insert, the latter being then adjusted by force to the cup by means of a shock or impaction applied to the rod by the surgeon to secure it in such a way that it is difficult, almost impossible, to remove.[0003]Said devices of the prior art are complicated to use and do not guarantee a reliable impaction force in the right direction. It is often the case that either the insert is misaligned in relation to the cup prior to its impaction, or the axis in w...
