Abstract
Description
- This invention pertains to surgical instruments, particularly to ultrasonic instrument assemblies and more particularly to such instrument assemblies with a sheath.
- Ultrasonic surgical instruments including incising instruments such as bone cutters and tissue cleaners of debriders are usually provided with sheaths that surround respective vibration-bearing shafts and define therewith channels for the passage of cooling liquid and/or suction for debris removal. Typically, such ultrasonic surgical instruments have probes or shafts that formed with a bend for rendering the instruments more ergonomic, that is, facilitative of accessing various surgical sites. The sheaths are generally rigid in part for maintaining the integrity of the flow channels but also for preventing or minimizing contact between the sheaths and the vibrating shafts, which may have an untoward effect on the sheaths. However, where an instrument shaft has a bend, it is in the interests of manufacturing expediency to provide a flexible connector at the bend. Such a connector joins two rigid sections of sheath, a proximal section and a distal section.
- A problem has been observed with the use of flexible connectors over the bends in ultrasonic instrument shafts. The flexible connector can be temporarily collapsed into contact with the vibrating instrument shaft, for instance, upon inadvertent contact with another object such as part of a patient or a surgeon's hand or arm. The contact can transmit ultrasonic vibration through the material of the connector, resulting in potential undesirable burning of the patient or the surgeon. The present invention seeks to eliminate or at least reduce this problem.
- A coupling member for an ultrasonic instrument assembly comprises, in accordance with the present invention, a tubular body member having a first port at a first end and a second port at a second end opposite the first end, the body member further having a lumen or channel extending from the first end to the second end so that the first and the second port communicate with one another. The body member is made of a flexible resilient material such as silicone rubber and at least one reinforcement element is joined to the body member. The reinforcement element is configured so as to at least inhibit a collapse of the body member.
- The reinforcement element preferably extends at least partially circumferentially about the body member. The reinforcement element may take the form of a helical or spiral insert. Alternatively, in another embodiment, the reinforcement member takes the form of a ring, e.g., a slotted ring. In the latter case, the reinforcement element is preferably one of a plurality of substantially identical reinforcement rings spaced from each other longitudinally along the tubular body member.
- Pursuant to alternative additional features of the present invention, the one or more reinforcement elements are either embedded in the flexible resilient material of the body member or attached to an inner surface of the body member.
- Typically, the reinforcement element is made of a more rigid material than the flexible resilient material of the body member. Where the reinforcement element is disposed on the inner surface of the body member, the reinforcement member is best made of a non-metallic material, such as a thermoplastic polymeric material. Where the reinforcement element is embedded in the body member, the reinforcement element may be made of a metal or alloy or a non-metallic material, such as a thermoplastic polymeric material.
- A sheath for an ultrasonic instrument assembly comprises, in accordance with the present invention, a substantially rigid first sheath section, a substantially rigid second sheath section, a tubular body member, and at least one reinforcement element. The body member is connected at one end to the first sheath section and at an opposite end to the second sheath section so that the first sheath section and the second sheath section communicate with one another. The body member is made of a flexible resilient material such as silicone rubber. The reinforcement element is joined to the body member and configured so as to at least inhibit a collapse of the body member.
- The reinforcement element may extend at least partially circumferentially about the body member. The reinforcement element may take the form of a helical or spiral insert and made be embedded in the body member or attached thereto along an inner surface thereof.
- The reinforcement element may be one of a plurality of reinforcement elements joined to the body member and collectively configured for at least inhibiting a collapse of the body member. Preferably, but not necessarily, the reinforcement elements are substantially identical and spaced longitudinally or axially along the body member. The reinforcement elements may be rings, integral or slotted.
- Preferably, the reinforcement element is made of a more rigid material than the flexible resilient material of the body member
- An ultrasonic instrument assembly comprises, in accordance with the present invention, a handpiece, a probe or instrument shaft extending from one end of the handpiece, a proximal sheath portion connected to the handpiece and surrounding a proximal end portion of the probe or instrument shaft, a distal sheath portion surrounding a distal end portion of the probe or instrument shaft, and a tubular coupling member. The coupling member has a lumen or channel, a proximal end section disposed in substantially fluid tight contact with the proximal sheath portion, and a distal end section disposed in substantially fluid tight contact with the distal sheath portion. The body member is made of a flexible resilient material and is provided with at least one reinforcement element joined to the body member. The reinforcement element is configured so as to at least inhibit a collapse of the body member.
- The reinforcement element may be a ring or helical or spiral insert. The reinforcement element is made of a more rigid material than the flexible resilient material of the body member. The reinforcement element may be embedded in the flexible resilient material of the body member or attached to an inner surface of the body member.
- Pursuant to another feature of the present invention, the tubular body member is provided with at least one expansion portion. The expansion portion may include an outwardly deformed portion of the tubular body member, such as a spiral bellows bubble or rib.
- In an ultrasonic tool assembly provided with a sheath coupling member as described herein, incidences of unintended burning of human tissue are reduced, owing to the reduction if not elimination of instances of sheath collapse particularly at bends in the shaft or probe of the ultrasonic tool assembly.

Also, multiple reinforcement elements may be provided, of similar or different geometries, the multiple reinforcement elements each being embedded in or attached to an inner or an outer surface of the body member. -
FIG. 12 depicts a sheath coupling orconnector 102 including atubular body member 104 having at least one expansion-facilitatingregion 106 for enhancing flexibility of the sheath coupling or connector. Expansion-facilitatingregion 106 may take the form of a bellows corrugation, e.g., a cross-sectionally semicircular spiraling rib, and more particularly a hollow spiraling rib having a smoothly arcuate convex semicircular cross-section.Tubular body member 104 is connected at one end to afirst sheath section 107 and at an opposite end to asecond sheath section 108. More particularly,sheath sections annular flanges 110 that insert intotubular body member 104. Alayer 112 of adhesive may be provided to fastentubular body member 104 to eachsheath section connector 102 defines ports at its opposite ends and a lumen that extends therebetween.Body member 104 has a straight configuration but bendable or curvable, as indicated by arrows 114, upon attachment tosheath sections Tubular body member 104 is made of a flexible resilient material such as silicone rubber or an equivalent composition. - Sheath coupling or
connector 102 further includes at least onehelical reinforcement element 116 in the form of a coiled strip disposed insidetubular body member 104, along aninner surface 118 thereof, longitudinally or axially staggered with, respect to spiralingexpansion rib 106.Helical reinforcement element 116 may be attached toinner surface 118 by alayer 120 of adhesive.Adhesive layer 120 may be co-extensive withreinforcement element 116. Alternatively,reinforcement element 116 may be joined totubular body member 104 only at opposite ends where the reinforcement element is provided with expandedterminal parts 122 and 124 fixed toinner surface 118 by respectiveadhesive layers helical reinforcement element 116 is force fit intotubular body member 104 and held in place at least in part by frictional forces. In that case tubular bellowsmember 104 is stretched overspiral reinforcement element 116. -
Reinforcement element 116 is made of a thermosetting plastic or polymer material and is designed so as to at least inhibit a collapse of sheathcoupling body member 102. Preferably, the interface betweenreinforcement element 116 andtubular body member 104 is watertight up to 15 psi. The design ofFIG. 12 offers the lowest stiffness against similar bending moments. - Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. For example, an ultrasonic coupling member or sheath connector as described herein could have reinforcement elements that are longitudinally extending strips or rods that are connected to end caps of a body member and thereby offer resistance to excessive deformation (collapse) of the coupling member or sheath connector. Such linear reinforcement elements may be embedded in or attached to an inner or an outer surface of the tubular body member.
- Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
