Abstract

Guiding device for pin comprises: a rigid body (1) with a special end (1a), a first drill (2) with smooth end (2a) and a second drill (3) with sharp end (3a). The first drill is introduced with the rigid body, its smooth end protecting the end of the body. The drill is retired to allow the body to be anchored on the bone. The second drill slides in the body and is hammered until a hole appears on the bone. A pin can finally be introduced at its place and attached to the bone.

Description

DISPOSITIF DE GUIDAGE POUR BROCHES DE CHIRURGIE OSSEUSE La présente invention concerne un dispositif de guidage en profondeur de bro ches utilisées en chirurgie osseuse. The present invention relates to a device for guiding depths of broaches used in bone surgery.

Ce dispositif permet de traverser avec précision les tissus mous sans bles ser. Il permet également de franchir la corticale osseuse à l'endroit exact sou haité. This device allows to cross accurately the soft tissues without wounds ser. It also makes it possible to cross the cortical bone at the exact spot desired.

Ce dispositif trouve son application en chirurgie osseuse ainsi qu'en radiologie interventionnelle ostéo-articulaire. This device finds application in bone surgery as well as in osteoarticular interventional radiology.

Il se compose de trois éléments métalliques<B>:</B> un corps de trocart (fig. à ex trémité particulière, un mandrin mousse (fg. 2) à extrémité arrondie, un man drin perforateur (fg.3) à extrémité pointue. It consists of three metal elements <B>: </ B> a trocar body (Fig. With special end, a foam mandrel (fg.2) with a rounded end, an end driller (fg.3) with an end pointed.

Il est un fait courant en chirurgie osseuse d'utiliser des broches métalliques pour mettre en place les matériels de fixation des foyers de fracture (ostéosyn thèse) ou pour repérer une lésion à enlever (biopsie, exérèse). Ces broches pré sentent une extrémité acérée, susceptible de blesser les tissus mous (vais seaux, nerfs etc.). It is a common fact in bone surgery to use metal pins to set up the fixation equipment for fracture sites (osteosyn thesis) or to identify a lesion to be removed (biopsy, excision). These pins have a sharp tip, which can injure soft tissue (eg buckets, nerves, etc.).

Plus ces broches sont fines, plus elles sont souples et donc difficiles ' diriger. Les inconvénients de ce procédé utilisé jusqu'à ce jour sont les suivants - le guidage d'un instrument souple à travers les tissus mous jusqu la fracture est difficile et risque d'aboutir à un mauvais positionnement de l'accessoire de fixation (vis, fiche etc.). The finer these pins are, the more flexible they are and therefore difficult to direct. The disadvantages of this method used to date are as follows - the guiding of a soft instrument through the soft tissues until the fracture is difficult and may lead to a bad positioning of the attachment (screw, card etc.).

- danger de perforation de vaisseaux profonds (artère fessière ou autre) par la pointe de la broche, avec risque d'hémorragie difficile à contrôler. - danger of perforation of deep vessels (gluteal artery or other) by the tip of the spit, with risk of haemorrhage difficult to control.

- danger de blessure d'un tronc nerveux (nerf sciatique ou autre), avec risque de séquelles motrices ou sensitives graves et définitives. - danger of injury to a nervous trunk (sciatic nerve or other), with risk of serious or definitive motor or sensory sequelae.

- danger de plaie viscérale avec risque d'infection immédiate ou différée. - risque de voir la broche souple glisser sur un plan osseux dur. Le dispositif selon l'invention permet de remédier à ces inconvénients. - danger of visceral wound with risk of immediate or delayed infection. - risk of the flexible pin sliding on a hard bone plane. The device according to the invention overcomes these disadvantages.

Il se compose de trois éléments métalliques<B>:</B> un corps de trocart rigide (fig. 1) à extrémité particulière non traumatisante, un mandrin mousse (fig. 2) ' extré mité arrondie rigoureusement adaptée au trocart, un mandrin perforateur (fig.3) à extrémité pointue à nutiliser qu'au contact de l'os pour perforer la corticale. It consists of three metallic elements <B>: </ B> a rigid trocar body (Fig. 1) with a particular non-traumatic end, a foam mandrel (Fig. 2) 'rounded end rigorously adapted to the trocar, a mandrel perforator (fig.3) with pointed end to be used only in contact with the bone to perforate the cortex.

L'ensemble rigide trocart-mandrin mousse peut être dirigé avec précision jus qu'à l'endroit souhaité et refoule, sans les blesser, les structures nobles. Arrivé au contact de l'os, le mandrin mousse est remplacé par le mandrin per forateur qui permet de pratiquer en toute sécurité un avant-trou dans corti cale osseuse, particulièrement dure. The rigid trocar-foam mandrel assembly can be directed precisely to the desired location and delivers the noble structures without hurting them. In contact with the bone, the foam mandrel is replaced by the perforator mandrel which makes it possible to practice safely a pilot hole in bone cortiale bone, particularly hard.

On retire alors le mandrin perforateur pour introduire la broche dans le corps du trocart. Cette broche peut ainsi pénétrer profondément dans l'os sans ris que de dévier. The perforating mandrel is then removed to introduce the spindle into the body of the trocar. This pin can penetrate deep into the bone without the risk of deflecting.

Selon une forme de réalisation préférentielle, le dispositif comprend trois com posants - La figure 1 montre un corps de trocart (1) : il s'agit d'un tube métallique ri gide cylindrique présentant à une extrémité (la) un embout de forme oh- vaire se terminant par un orifice de section ronde coupante et à l'autre ex trémité<B>(1b)</B> un embout portant deux ailettes permettant une meilleure prise en main. According to a preferred embodiment, the device comprises three components - FIG. 1 shows a trocar body (1): it is a cylindrical, cylindrical metal tube having at one end (la) an oh-shaped tip - void ending with a cut round section hole and the other end <B> (1b) </ B> a tip carrying two fins for better grip.

- La figure 2 montre un mandrin mousse (2), tige métallique cylindrique s'emboîtant avec précision dans le corps du trocart, terminée par une ex trémité arrondie (2a) dont le dessin continue le profil olivaire de l'extrémité (la) du trocart. L'autre extrémité comporte une tète plate (2b). FIG. 2 shows a foam mandrel (2), a cylindrical metal rod fitting precisely into the body of the trocar, terminated by a rounded end (2a) whose design continues the olivary profile of the end (1a) of the trocar. The other end has a flat head (2b).

- La figure 3 montre un mandrin perforateur (3), tige métallique cylindrique s'emboîtant avec précision dans le corps du trocart à la place du mandrin mousse, se terminant par une extrémité pointue (3a) qui dépasse l'extrémité (la) du trocart. L'autre extrémité présente une tête plate (3b) qui permet la percussion par un marteau. L'emploi dispositif s'effectue en deux phases - Après incision cutanée de longueur adaptée au matériel à mettre place (et dissection prudente en profondeur), on introduit le trocart (1) muni du mandrin mousse (2) dans l'orifice pratiqué, selon la direction préalablement choisie. progression de l'ensemble est facilitée par des mouvements de rotation axiale que permet la section arrondie du dispositif. La tenue du tro cart est facilitée par les ailettes (lb) et la pénétration se fait par pression du talon de la paume de la main sur la tête plate (2b) du mandrin mousse jus qu'au contact osseux. On retire le mandrin mousse tout en maintenant en place le trocart dont le bord coupant de l'extrémité (la) est ainsi demasqué et permet l'ancrage dans le périoste et limite le risque de mobilisation in tempestive du trocart. FIG. 3 shows a perforating mandrel (3), a cylindrical metal rod fitting precisely into the body of the trocar in place of the foam mandrel, terminating in a pointed end (3a) extending beyond the end (1a) of the trocar. The other end has a flat head (3b) which allows percussion by a hammer. The device is used in two phases - After cutaneous incision of length adapted to the material to put place (and careful dissection in depth), the trocar (1) with the foam mandrel (2) is introduced into the orifice made, according to the direction previously chosen. progression of the assembly is facilitated by movements of axial rotation that allows the rounded section of the device. The holding of the cart is facilitated by the fins (lb) and the penetration is done by pressing the heel of the palm of the hand on the flat head (2b) of the mandrel foam until bone contact. The foam mandrel is removed while maintaining in place the trocar whose cutting edge of the end (la) is thus demasquered and allows anchoring in the periosteum and limits the risk of mobilization in tempestive trocar.

- On introduit ensuite dans le trocart (1) le mandrin perforateur (3) dont la progression dans la corticale osseuse est obtenue par quelques coups de marteau sur la tête plate (3b). Le trocart toujours maintenu en place grâce à son ancrage, on retire le mandrin perforateur que l'on remplace par une broche qui vient se piquer dans le trou ménagé dans la corticale. Cette bro che peut ainsi être enfoncée à la profondeur voulue tout en gardant, grâce à ce procédé, la direction initiale. - Then introduced into the trocar (1) the perforating mandrel (3) whose progression in the cortical bone is obtained by a few hammer strokes on the flat head (3b). The trocar still held in place thanks to its anchoring, we remove the perforating mandrel which is replaced by a pin that is pricked in the hole in the cortex. This pin can thus be depressed to the desired depth while keeping, through this method, the initial direction.

Le dispositif selon l'invention est particulièrement destiné à la chirurgie ou à la radiologie interventionnelle de l'appareil locomoteur.The device according to the invention is particularly intended for surgery or interventional radiology of the musculoskeletal system.
