A surgical tool such as a liposuction cannula is equipped with a sensor at the tool tip. The sensor continuously analyzes the type of tissue in contact with the tip based on the electrical properties of the tissue. When encountering a tissue type that should not be disturbed, the action of the surgical tool is stopped automatically. When used for liposuction, the cannula is mechanically decoupled from the handle when the wrong type of tissue is detected thus minimizing the inertia of the part that needs to be stopped. Besides electrical sensing, other sensors, such as mechanical or ultrasonic, can be used at the tip of the surgical tool or cannula to differentiate between tissue types

This invention relates to a device and method for improving the surgical procedure of soft tissue removal by aspiration and more particularly to a device and method utilizing laser energy directed substantially across the inlet port to more readily and safely facilitate the separating of soft tissue from a patient in vivo. This invention has immediate and direct application to the surgical procedure of liposuction or body contouring as well as application in the surgical procedures of other soft tissue removal such as brain tissue, eye tissue, and other soft tissue inaccessible to other soft tissue aspiration techniques.

A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery The cannula (10) can be connected to the handle (12) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (12) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling. A vacuum hose (26) is connected to the cannula (10) such that vacuum pressure can be exerted through the cannula (10) for aspirating severed fat tissue. Preferably, the connector (24) radially offsets the cannula (10) from the reciprocating member (14) to a position which is axially in alignment with the vacuum hose (26); thereby avoiding bend regions and enhancing suction.

The present invention provides a method for preparing homogeneous stem cells and/or precursor cells in a large amount, in a simple and efficient manner, from human (in particular, the subject per se). The present invention further provides a method for preparing tissue implant or graft in a large amount by the use of the stem cells and/or precursor cells of the present invention. The present inventors have unexpectedly discovered that an aspirate from liposuction contains a large number of stem cells and have established a method for preparing stem cells from such an aspirate from liposuction, and thereby achieved the above-mentioned object.

A method and apparatus is disclosed for mechanically-assisted liposuction treatment. The apparatus includes a hand-holdable housing, an electro-cauterizing cannula assembly, and a reciprocation mechanism. The hand-holdable housing has a cavity adaptable for receipt of a portion of the electro-cauterizing cannula assembly. The electro-cauterizing cannula assembly has a distal end and a proximal end and at least one aspiration aperture about the distal end. The reciprocation mechanism is disposed within the housing and is operably associated with either the cannula so that the cannulas can be selectively caused to reciprocate relative to the housing. As the cannula is caused to reciprocate relative to the housing, the aspiration aperture formed through the distal end of the cannula assembly is caused to undergo periodic displacement. During aspiration of tissue, high-voltage RF power signal supplied to an electro-cauterizing electrode structure formed about each reciprocating aspiration aperture to effect hemostasis thereabout. Such hemostasis is achieved by causing protein molecules within aspirated tissue to coagulate in response to the high-voltage RF signal being supplied across the electro-cauterizing electrode. In the preferred embodiments, the amount and rate of such aspiration aperture displacement is controllably adjustable. The cannula assembly is releasably detachable from the hand-holdable housing to facilitate cleaning and sterilization of the cannula assembly and the housing.

An ultrasonically pulsating high-pressure fluid jet coupled with a suction system serve as a tissue harvesting device. The pulsated fluid jet disrupts tissue, permitting both harvesting of cells for therapeutic delivery, and as a surgical dissector and aspirator, for liposuction, soft tissue dissection, etc. The jet is delivered to the target tissue through a cannula, coupled to an aspiration system. An ultrasonically actuated rod vibrates within the cannula engaging a nozzle, disrupting the fluid jet into droplets, permitting tuning of the jet to the resonant frequencies and impact pressures necessary to dissociate the target tissue. A suction recovery system may be separated or integrally formed with the fluid jet cannula, and is linked by a closed tubing system appropriate for sterilization and subsequent delivery of the harvested cells/tissues with or without growth factor or matrix addition for human re-implantation or for in vitro expansion for later re-implantation.

Systems and methods for liposuction are disclosed that use a lipid-emulsifying fluid to produce fluid jet disruption and Venturi pumping of fat tissue. The device includes a flexible or rigid probe with an inlet lumen and an outlet lumen. The inlet lumen is in fluid communication with a pump capable of producing high pressures, e.g., 250-3500 psi. The pump is in fluid communication with a volume of a liquid such as sterile saline that may or may not contain a fat emulsifier. At the end of the inlet lumen is a conical constriction or a port that accelerates the emulsification fluid to high velocities. The high velocity jet stream creates a low pressure area that draws the fat tissue into proximity with the jet stream. The jet stream directly and through turbulent vortices breaks up the fat cells. The lipid of the fat cells is subsequently emulsified by the emulsification fluid.

A method and apparatus is disclosed for mechanically-assisted liposuction treatment. The apparatus includes a hand-holdable housing, an electro-cauterizing dual cannula assembly, and a reciprocation mechanism. The hand-holdable housing has a cavity adaptable for receipt of the electro-cauterizing cannula assembly. The electro-cauterizing cannula assembly has a distal end and a proximal end and at least one aspiration aperture about the distal end. The reciprocation mechanism is disposed within the housing and is operably associated with the inner cannula so that the inner cannula can be selectively caused to reciprocate relative to the stationary outer cannula mounted to the hand-supportable housing. As the inner cannula is caused to reciprocate relative to the housing, the aspiration aperture formed through the distal end of the cannula assembly is caused to undergo periodic displacement. During aspiration of tissue, high-voltage RF power signal supplied to electro-cauterizing electrode structures formed about each reciprocating aspiration aperture to effect hemostasis thereabout. Such hemostasis is achieved by causing protein molecules within aspirated tissue to coagulate in response to the high-voltage RF signal being supplied across the electro-cauterizing electrode. In the preferred embodiments, the amount and rate of such aspiration aperture displacement is controllably adjustable. The cannula assembly is releasably detachable from the hand-holdable housing to facilitate cleaning and sterilization of the cannula assembly and the housing.

The liposuction apparatus (1) comprises in combination a tubular canula (3) having at its distal extremity (18) one or more suction orifices (24) and connected at its proximate extremity (19) to a suction source (14) in communication with these orifices, and a hand piece (2) delivering a spray of working liquid (4) under pressure. The hand piece delivers the spray of liquid under pressure using a conduit opening into an ejection orifice which, when the canula is attached to the hand piece, is located opposite an ejection orifice in the canula located at its distal extremity. A liposuction method using the apparatus is also taught. This invention is of interest to manufacturers and users of surgical equipment.

A surgical instrument is provided, principally for use with endoscopic plastic surgery, and adapted for insertion into an incision for engaging subcutaneous tissue, fat, fascia or muscle (STFFM) through a remote access incision, grasping the STFFM, and enabling it to be moved to another location. The STFFM is grasped preferably by engaging it with a needle and passing a suture through it, with the suture being locked by engagement via a hook, all at a location inside the skin that is remote from the opening. This enables the sutured STFFM to be moved, in any direction, but most often toward the incision as the inserted portion of the instrument is removed. A vacuum and an external clamp are provided, for facilitating engagement of the portion of the STFFM that is to be sutured. The instrument is usable for facelift surgery, midface surgery, brow surgery, neck lift, scalp reduction, endoscopic mastopexy, endoscopic thigh lift, endoscopic tummy tuck, and for any other technique where it is desired to shift STFFM from one location to another location, as for example, in the correction of undesirable liposuction results.

An electro-cauterizing cannula assembly for use in a power-assisted liposuction instrument having a hand-holdable housing and a mechanism for reciprocating the cannula assembly. The electro-cauterizing cannula assembly includes an inner and an outer cannula, each having a distal and proximal end and at least one aspiration aperture about the distal end. The inner cannula is disposed within the outer cannula and the inner and outer aspiration apertures are in at least partial registration to form an effective aspiration aperture. During aspiration of tissue, high-voltage RF power signals are supplied to the inner and outer cannulas to effect hemostasis about the reciprocating aspiration aperture. Such hemostasis is achieved by causing protein molecules within aspirated tissue to coagulate in response to the high-voltage RF signals being supplied across the reciprocating cannulas. The cannula assembly is releasably detachable from the hand-holdable housing to facilitate cleaning and sterilization of the same.

A liposuction apparatus and method optionally having a sonic or ultrasonic source with an axial lumen passage in which the shaft can be made to reciprocate (oscillate) in a non-rectilinear fashion. The apparatus may also contain the concomitant use of rectilinear reciprocation motion in addition to ultrasonic motion or energy along the shaft of the apparatus. The advantages of the liposuction apparatus are as follows: 1) non-rectilinear single shaft reciprocating cannula, 2) sonic or ultrasonic energy delivered to the distal tip, 3) rectilinear reciprocating cannula with ultrasonic energy along the shaft from the handle, and 4) any of the above reciprocating components powered by excess unused vacuum capacity in the liposuction aspirator (suction engine) apparatus. There are three (3) primary sources of energy applied to the cannula shaft: the first is the oscillating surgeon's arm motion (approximately 1-2 hertz); the reciprocating motion (of about 100 Hz); and the optional concomitant motion as delivered by the ultrasonic energy (e.g. 25 KHz).

An apparatus and method for simultaneously applying a compressive and a reciprocating force to underlying adipose cells from a location external to a patient's skin to rupture or otherwise remove the adipose cells within a subcutaneous tissue region. The adipose cells are ruptured through the mechanical application of compression and shearing forces. The patient's body then re-absorbs and expels the ruptured cells. This eliminates the need for invasive liposuction and the trauma associated with invasive liposuction. Various mechanical devices may be employed to impart the compressive and shearing forces.
