Embodiment Construction

[0051] The present invention relates to a surgical hand-held device for treating (cutting, drilling, etc.) biological tissues of different densities by means of instruments (or plug devices).

[0052] In order to alleviate the disadvantages of prior art devices, the handheld device of the present invention advantageously combines two different technologies: ultrasonic vibration of the plug device with the main impact movement and rotary drive of the plug device with suitable rotary drive means.

[0053] The hand-held device is thus suitable for simultaneously applying a rotary movement and a percussion movement to a cutting and / or drilling tool (ie the plug device), and said movements can be performed alternately or simultaneously.

[0054] will be referred to below figure 2 , image 3 , Figure 4A with Figure 4B A surgical handpiece 200 in a first embodiment of the present invention will be described.

[0055] More specifically, figure 2 It is a schematic side cross-sec...

Abstract

The invention relates to a surgical handpiece (200) comprising a housing (207) intended to receive an insert (210), a piezoelectric ultrasonic transducer (219) comprising a piezoelectric motor (220) arranged between a counter-mass (224) and an amplifier part (226), the piezoelectric transducer (219) being able to transmit ultrasound waves from a distal end (226b) of the amplifier part (226) present in the housing (207), and rotation driving means present in the housing (207), the rotation driving means being movable independently of the piezoelectric ultrasonic transducer (219), the latter being static in relation to the handpiece (200).

Description

technical field [0001] The present invention relates to a surgical treatment device, more particularly, to a device for treating biological tissue (enamel, dentin, mucosa, bone, etc.) or implanting a prosthesis (such as a graft, prosthesis or any other active Surgical handheld devices for implantable devices (heart valves, etc.). [0002] The invention has more particular application, for example, in the cutting and / or drilling of biological tissue of various densities close to delicate anatomical structures (such as membranes or vital organs) that require protection. Background technique [0003] Traditionally, for example when performing osteotomy (e.g. cutting bone from the knee), surgical hand-held devices are used which are provided with a micro-motor which drives a rotating cutter whose rotational movement is used to efficiently way into bone tissue. The same type of surgical handpiece is preferably used when it is necessary to drill holes or alter recesses to accomm...
