Benefits of technology

The present invention is providing a surgical tool and a coupling device that allows the tool to be attached to a motorised handpiece, which can irrigate the operating field precisely and in sufficient quantity. The coupling device is simple and compact, and includes a support part, a sleeve, and a bushing for holding the physiological saline solution. The invention also ensures rigid axial and rotational locking between the tool shank and the drive shaft of the surgical instrument. The tool can be easily mounted and removed during operation. Overall, the present invention improves the precision and effectiveness of surgical tools.

Problems solved by technology

However, the end 18 through which the jet of fluid emerges from pipe 10 cannot be arranged past coupling bushing 4, since this would prevent tool 6 from being easily mounted / removed.
Irrigation of the working area is thus not precise and does not always occur in sufficient quantities.

Embodiment Construction

[0018]The present invention proceeds from the general inventive idea that consists in providing a coupling device and a tool for a motorised surgical instrument which allow in particular precise irrigation of the operating field in sufficient quantities by means of a fluid such as physiological saline solution. The coupling device therefore both allows the tool to be rigidly coupled to the surgical instrument drive shaft and allows a channel extending axially into the tool shank to be placed in communication with an external fluid source. Consequently, the fluid emerges from the tool shank at the active area thereof, i.e. as close as possible to the operating field, which concealed by tissue, is otherwise difficult to access particularly for tools of a certain length. Moreover, the coupling device has a limited number of parts, is compact and free from asperities, which makes the surgical instrument easier to handle. The practitioner becomes less tired and his movements are therefor...

Abstract

Coupling device between a drive shaft (26) of a surgical instrument (28) and a tool (34; 106), characterized in that the coupling device (20) includes a fluid feed element fed from outside the coupling device (20) and communicating with a channel (78; 110) arranged in the tool (34; 106) and which emerges at a location along the length of the tool (34; 106).

Description

[0001]This application claims priority from European Patent Application No. 09174374.0 filed Oct. 28, 2009, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention concerns a coupling device between the drive shaft of a surgical instrument and a tool. More specifically, the present invention concerns a coupling device between a motorised surgical instrument and a rhinoplasty tool.BACKGROUND OF THE INVENTION[0003]Rhinoplasty is a branch of cosmetic surgery that aims to redesign the profile of a patient's nose. One particular case is correction by bone ablation of the bump on the ridge of the nose that is more pronounced in some people than in others. In order to perform this ablation, the surgeon uses motorised handpieces that impart specific back and forth movements to saw, file or plane type tools. An example of this type of handpiece is illustrated in FIG. 1 annexed to this Patent Application. Designated as a whole by th...
