Abstract
Description
La présente invention a pour objet une broche utilisée en chirurgie, plus particulièrement pour la chirurgie de la main selon la méthode dite de KAPANDJI. The present invention relates to a pin used in surgery, more particularly for hand surgery according to the so-called KAPANDJI method.
L'embrochage intra-focal selon la méthode KAPANDJI pose des problèmes non imputables à la techniques mais plus souvent dus aux broches de KIRSCHNER. Il est nécessaire de pallier deux problèmes : la migration trop importanteet le conflit entre le bout distal de la broche et les éléments sous-cutanés et cutanés. Intra-focal skewering according to the KAPANDJI method poses problems not attributable to the technique but more often due to KIRSCHNER pins. It is necessary to overcome two problems: excessive migration and the conflict between the distal end of the spindle and the subcutaneous and cutaneous elements.
Conformément à l'invention, ce résultat est obtenu avec une broche utilisée en chirurgie, plus particulièrement pour la chirurgie de la main selon la méthode dite de KAPANDJI, caractérisée en ce qu'elle comporte un bout proximal en pointe avec un butoir anti-migration et un bout distal recouvert d'un embout de protection. According to the invention, this result is obtained with a spindle used in surgery, more particularly for hand surgery according to the so-called KAPANDJI method, characterized in that it has a proximal tip with an anti-migration stopper. and a distal end covered with a protective tip.
On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels - la figure 1 est une vue en élévation latérale d'une broche conforme à l'invention ; - la figure 2 est une vue schématique de la broche positionnée dans la main du patient - la figure 2A est une vue agrandie de la partie distale, une fois positionnée - la figure 2B est une vue agrandie de la partie proximale, une fois positionnée. The invention will be better understood with the aid of the description given below of an embodiment given by way of nonlimiting example, with reference to the appended drawings in which - FIG. 1 is an elevation view side of a spindle according to the invention; - Figure 2 is a schematic view of the pin positioned in the patient's hand - Figure 2A is an enlarged view of the distal part, once positioned - Figure 2B is an enlarged view of the proximal part, once positioned.
La broche (1) se compose essentiellement d'un corps (2), d'une pointe (3) en partie proximale et d'une extrémité distale (4) munie d'un capuchon de protection (5). The pin (1) essentially consists of a body (2), a tip (3) in the proximal part and a distal end (4) provided with a protective cap (5).
La pointe comporte un butoir anti-migration (6) qui empêche le déplacement de la broche, avec reconstitution de l'os au niveau d'une gorge (7). Ceci est schématisé à la figure 2B. The tip has an anti-migration stopper (6) which prevents displacement of the spindle, with reconstruction of the bone at the level of a groove (7). This is shown schematically in Figure 2B.
La protection de l'extrémité distale par l'embout (5) évite la lésion du tissu cutané correspondant. The protection of the distal end by the end piece (5) prevents damage to the corresponding skin tissue.
De préférence la pointe sera en diamant, le reste de la broche pouvant être en acier ou en titane. Preferably the point will be made of diamond, the rest of the pin may be made of steel or titanium.
La méthode opératoire d'embrochage selon KAPANDJI est la variante, pour la réduction des fractures du poignet. The operative method of skewering according to KAPANDJI is the variant, for the reduction of wrist fractures.
On met en place à force une broche par la pointe en diamant qui permet leur utilisation à l'aide d'une simple poignée manuelle car la pénétration est aisée et on sent à la main la butée de la broche après sa pénétration au niveau de la corticale opposée. A pin is forced into place by the diamond point which allows their use with a simple manual handle because the penetration is easy and you feel the pin stop by hand after its penetration at the cortical opposite.
Après avoir mis en place les 2 ou 3 broches selon le type de fracture à traiter, on réalise le contrôle radiologique. After having installed the 2 or 3 pins depending on the type of fracture to be treated, the radiological control is carried out.
On sectionne à la pince coupante le bout distal de la broche en refoulant au plus loin la peau. The distal end of the spindle is cut with a pair of pliers, pushing the skin as far as possible.
Puis on couvre le bout distal par l'embout métallique (5) que l'on déforme en l'écrasant entre les deux mors d'une pince coupante. Il devient ainsi adhérent à la broche et on peut le couvrir par le tissu cutané qui est fermé par un à deux points de suture. Then the distal end is covered by the metal tip (5) which is deformed by crushing it between the two jaws of a cutting pliers. It thus becomes adherent to the pin and can be covered by the skin tissue which is closed with one or two stitches.
Une attelle plâtrée pour 10 à 21 jours est souvent associée selon les opérateurs à la fin de cette intervention. A plaster splint for 10 to 21 days is often associated according to the operators at the end of this intervention.
Les avantages du dispositif selon l'invention sont multiples et partent des constatations chimiques suivantes - la pénétration osseuse est aisée. La traversée de la corticale opposée se fait sans grande difficulté - la sensation manuelle d'arrêt lors de la pénétration évite de pousser trop loin cette broche et donc, de léser les éléments tendineux et vasculo-nerveux ; de plus, elle peut dispenser d'un contrôle radioscopique - l'embout de protection distal joue bien son rôle et évite les blessures secondaires des tendons et du tissu cutané. Il adhère bien à la broche et facilite son repérage lors de l'ablation du matériel - on constate fréquemment à l'ablation de ces broches leur bonne tenue. The advantages of the device according to the invention are multiple and start from the following chemical observations - bone penetration is easy. The crossing of the opposite cortex is done without great difficulty - the manual sensation of stopping during penetration avoids pushing this pin too far and therefore, damaging the tendon and vascular-nervous elements; moreover, it can dispense with radioscopic control - the distal protective tip plays its role well and avoids secondary injuries to the tendons and skin tissue. It adheres well to the spindle and makes it easier to identify when ablating the material - we often see when ablating these pins that they hold up well.
Ceci provient de différents éléments
le débordement de la pointe en diamant agissant comme un butoir rétrograde,
le diamètre de la broche qui pénètre la corticale est inférieur à celui des broches utilisées jusqu'alors,
en dernier lieu, l'embout distal aide, en s'appuyant sur la peau, à empêcher le recul de cette broche.This comes from different elements
the overflow of the diamond point acting as a retrograde stop,
the diameter of the spindle that enters the cortex is less than that of the pins used until now,
lastly, the distal tip helps, by leaning on the skin, to prevent the recoil of this pin.
Enfin, ce matériel ne nécessite pas une instrumentation particulière pour sa mise en place. Finally, this equipment does not require any particular instrumentation for its installation.
