Tissue Treatment Apparatus with Interchangeable Instrument/Accessories

FIELD OF THE INVENTION

This invention relates to the field of surgical instruments, and in particular to an instrument for laser treatment of a targeted tissue of a patient with the addition of a variety of treatment tips for performing specific functions.

BACKGROUND OF THE INVENTION

Surgical instruments can be designed and constructed as rigid, articulated and/or flexible devices in order to achieve specific effects on target tissues, such as cutting, ablation or coagulation of tissue. In addition, surgical instruments can be designed and constructed as “cold” or mechanical devices that achieve one or more desired effects mechanically, or can be designed and constructed as “hot” devices that are energized by different energy sources, such as, for instance, radio frequency, ultrasound and laser energy sources, to manipulate/treat tissue. Other surgical instruments can be designed and constructed as both “cold” and “hot” devices that perform both cold and energized tissue manipulation/treatment.

An advancement of laser surgery includes a tissue-treating laser beam that can cut tissue at a distance from a laser energy delivery device without requiring direct contact between a laser treatment instrument and the target tissue. The distance between, for example, the tip of a laser instrument and the target tissue can be determined by a surgeon based on his experience and judgment during a surgical operation. This is one way a surgeon controls the power density applied to the target tissue. However, in other cases, it is preferred or required to maintain a specific distance between the target tissue and the laser instrument tip. In these cases, a standoff is typically used to help to attain and maintain a preferred or required distance between the laser instrument tip and the target tissue.

Other surgical procedures may require a backstop mechanism that prevents a laser beam from reaching non-target tissue beyond the intended tissue treatment site. Other surgical procedures also may require the ability to couple the laser beam to energetic effects of an ultrasonic energy or radio frequency energy or to some mechanical dissection apparatus.

Thus, it is desirable that a tissue treatment instrument be designed and constructed to receive or accept, and to interchange with, multiple instruments or accessories, with each instrument or accessory constructed and arranged for a specific procedure and/or for a particular mode of use of the treatment instrument. In addition, it is desirable that the tissue treatment instrument include an instrument and accessories tip or base that is adapted to permit the instrument to receive or accept, and to interchange with, multiple instruments or accessories. Such a treatment instrument and accessories base permits a surgeon or operator to couple any of multiple instruments or accessories to the instrument, such as, for example, for a specific procedure or mode of use of the instrument. Such an instrument and accessories base facilitates flexibility in terms of various procedures that the instrument may perform, various modes of use of the instrument, as well as various instruments or accessories that the instrument can receive or accept. Such instruments or accessories may include, but are not limited to, any of a variety of standoffs, backstops, dissecting devices, aiming devices, and other procedure- or mode of use-specific elements.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, in one aspect, the invention provides a tissue treatment instrument 10 constructed and arranged for surgical and medical procedures and operations. In one embodiment, the tissue treatment instrument 10 is a laser instrument including a rigid tube 12 operatively connected to a laser source 24 and constructed and arranged to receive a waveguide 16 for delivery of a laser beam to target tissue. The rigid tube 12 includes at its distal end or tip an accessories base 14 constructed and arranged to receive or accept one or more instruments or accessories according to the invention that are constructed and arranged for any of a variety of surgical and medical procedures and operations, as well as for any of a variety of modes of use. In one embodiment, the accessories base 14 is designed and configured as a separate mountable/connectable unit for mounting/connecting to the instrument 10, e.g., per a user's need. In another embodiment of the accessories base 14, the accessories base 14 is designed and configured integral with the instrument 10 such that the accessories base 14 and the instrument 10 are one unit onto which various instruments or accessories may be mounted/connected.

In another embodiment according to the invention, an endoscope replaces the treatment instrument 10. The wave guide 16 is received by a working channel defined within the interior of the endoscope and passes through the channel and the distal end of the endoscope. In this embodiment, the accessories base 14 is designed and configured as a mountable/connectable unit that is mounted/connected to the endoscope distal end.

In a further embodiment according to the invention, the instrument 10 may be constructed and arranged for procedures and operations including, but not limited to, ENT (ear, nose, and/or throat), gynecological, and neurosurgical procedures and operations, and may be constructed and arranged to provide, in addition to the laser energy delivery, other types of energy, such as radio frequency and/or ultrasound energy.

In other embodiments according to the invention, the instrument 10 may facilitate various methods of delivery of treatment and may be constructed and arranged as a rigid, articulated and/or flexible instrument 10 to achieve such treatment methods. The instrument 10 may also be a part of a wholly or partially articulated robotic instrument.

Regardless of the type of tissue treatment instrument 10, the accessories base 14 according to the invention is constructed and arranged to receive or accept a variety of instruments or accessories. The accessories base 14 and the instruments or accessories, as described in detail below, are constructed and arranged to permit connection and detachment of the instruments or accessories to the base 14 and to enable an interchange of instruments or accessories, such as, for example, during a procedure or an operation. The flexibility that the accessories base 14 and the instruments or accessories provide help to enable quick and relatively easy attachment and removal of the instruments or accessories to and from the accessories base 14 to thereby enable a quick change or alteration of instruments or accessories of the instrument 10 according to a preferred or required action on target tissue.

The invention anticipates that the instrument 10 according to the invention and, in particular, the accessories base 14 and the multiple accessories or instruments the base 14 accepts or receives according to the invention, are not limited and may include a variety of instruments and accessories or instruments for use in surgical, medical and other procedures and operations. The invention is disclosed below in connection with a laser laparoscope for illustrative purposes only and is not intended to limit the scope and spirit of the invention.

Still referring to FIG. 1, the laser instrument 10 (shown as a laparoscopic instrument in FIG. 1 only for the purposes of illustration) includes a rigid tube 12 defined with an elongate hollow member that is operatively connected to a handle 20. A flexible waveguide 16 is operatively coupled into and through the tube 12 and is maintained in place relative to the tube 12 and the handle 20. The wave guide 16 is operatively connected at its proximal end to the laser source 24. The tube 12 is configured to permit its insertion into, for example, an abdominal cavity 50, e.g., via a trocar 22, through a surgical incision in the exterior 52 of the abdominal cavity.

The distal end or tip of the tube 12 includes the accessories base 14 according to the invention. The accessories base 14 may be mounted or connected, e.g., removably, to the distal tip of the tube 12, or the accessories base 14 may be an integral part of the distal end or tip. The accessories base is constructed and arranged to receive or to accept one or more instruments or accessories according to the invention. The accessories base 14 thereby enables attachment or removal of multiple instruments or accessories to the instrument 10, such that, the instrument 10 may be used in one or more surgical, medical or other procedures, and/or the instrument 10 may be used in one or more modes of use.

The accessories base 14 is designed and configured with any of a variety of mounting or connection devices and configurations that facilitate mounting or connecting of an instrument or accessory to the accessories base 14. Any particular mounting or connection device and configuration of the accessories base 14 complements, or is similar to, a mounting or connection device and configuration of an instrument or accessory for use with the instrument 10. Such mounting or connection devices and configurations can include, but are not limited to, complementary threads along the accessories base 14 and instrument or accessory (for screw-type connections), snap connectors, Luer lock connectors typically used in surgical equipment, and other suitable connectors. In particular, such mounting or connection devices and configurations are suitable for permitting easy and quick connection and removal of an instrument or accessory to and from the accessories base 14.

In this manner, the accessories base 14 readily and easily receives or accepts and thereby mounts or connects an instrument or accessory to the instrument 10. In one embodiment of the invention, the accessories base 14 includes a mounting or connection device and configuration that are universal with respect to a multiple of instruments or accessories, such that, the accessories base 14 receives or accepts and thereby mounts or connects any of the multiple of instruments or accessories to the same instrument 10. The instrument 10 is thereby flexible in terms of the modes of use of the instrument 10, such as, for example, during a specific procedure/operation and in terms of the variety of procedures/operations in which the instrument 10 may be used. Specific instruments and accessories according to the invention are described in detail below with reference to FIGS. 2-7. The invention, however, is not limited to the instruments and accessories that are disclosed below and envisions that any of a variety of instruments and accessories may be used with the accessories base 14.

Referring to FIG. 2, in one embodiment of the invention, an instrument or accessory according to the invention includes a standoff or spatula 26 that is designed and configured to removably mount or connect to the accessories base 14. As mentioned above, in one embodiment of the accessories base 14 according to the invention, the accessories base 14 is designed and configured as a separate mountable/connectable unit for mounting/connecting to the instrument 10. In another embodiment of the accessories base 14 according to the invention, the accessories base 14 is designed and configured integral with the instrument 10 such that the accessories base 14 and the instrument 10 are one unit onto which various instruments or accessories may be mounted/connected. The standoff 26 may be constructed and arranged with a mounting or connection device and configuration for mounting/connecting to and removing from the accessories base 14. The standoff 26 may also be constructed and arranged to control the distance between the wave guide 16, which delivers the laser beam, and target tissue 54 once the standoff 26 is connected to the accessories base 14. Maintaining a specific distance between the wave guide 16 and the target tissue 54 helps to prevent or at least minimize accidental or inadvertent contact between the wave guide 16 and the target tissue 54. In addition, maintaining a specific distance helps to prevent or at least minimize over exposure of the target tissue 54 to laser energy since the laser beam can cause high power densities at short working distances. The standoff 26 also helps a surgeon to better estimate the expected location on the target tissue 54 where a laser beam emitted from the wave guide 16 will hit. The standoff 26 is more critical in the absence of an aiming beam. The standoff 26 is further designed and configured with such a profile size that it will not interfere in passing the instrument 10 through a trocar 22 or other device that enables such passage when the standoff 26 is mounted on the accessories base 14.

Referring to FIG. 3, in another embodiment of the invention, an instrument or accessory according to the invention includes a backstop 28 that is designed and configured to removably mount or connect to the accessories base 14. In one embodiment of the accessories base 14 according to the invention, the accessories base 14 is designed and configured as a separate mountable/connectable unit for mounting/connecting to the instrument 10. In another embodiment of the accessories base 14 according to the invention, the accessories base 14 is designed and configured integral with the instrument 10 such that the accessories base 14 and the instrument 10 are one unit onto which various instruments or accessories may be mounted/connected. The backstop 28 may be used with target tissue 54 that is relatively thin and where damage behind the target tissue 54 needs to be avoided or at least minimized. The backstop 28 is designed and configured to absorb excessive energy that is not absorbed by or passes through the target tissue 54. As shown in FIG. 3, once attached to the accessories base 14, the backstop 28 is positioned to help to prevent or to at least minimize damage behind the target tissue 54. In addition to its function as a back stop, the backstop 28 also helps to determine the cutting distance similar to that ability provided by the standoff 26. One of ordinary skill in the art would appreciate that a variety of backstops 28 of different sizes, thicknesses and materials may be employed with the accessories base 14 as may be dictated by the required application/procedure, organ geometry, beam spot sizes and other parameters of the procedure and/or the target tissue 54, such that a surgeon may select the most appropriate backstop 28 for use with the instrument 10. The backstop 28 is further designed and configured with a profile and size such that it will not interfere in passing the instrument 10 through a trocar 22 or other device that enables such passage when the backstop 28 is mounted on the accessories base 14.

Referring to FIG. 4, in a further embodiment of the invention, an instrument or accessory according to the invention includes a beam deflector 30 that is designed and configured to removably mount or connect to the accessories base 14.

The beam deflector 32 with mirror 33 may be positioned or oriented to deflect a laser beam at any of a range of other predetermined or defined angles. As shown in FIG. 5, the deflector 32 with mirror 33 may be positioned at any preferred or selected angle. Accumulation of tissue debris on the mirror should be avoided and various mechanisms may be employed for such purpose. One example of such a mechanism to prevent or to minimize the accumulation of debris on the mirror 33 is an accessory channel, such as accessory channel 44 shown in and discussed below with reference to FIG. 7, defining a hollow conduit through which a fluid, such as a saline solution, may be introduced to impinge upon mirror 32 and wash away any debris on mirror 33. The beam deflector 32 with mirror 33 is further designed and configured with a profile and size such that it will not interfere in passing the instrument 10 through a trocar 22 or other device that enables such passage when the beam deflector with mirror 33 is mounted on the accessories base 14.

Referring to FIG. 6, in another embodiment of the invention, an instrument or accessory according to the invention includes a dissection device 34 that is designed and configured to removably mount or connect to the accessories base 14. In one embodiment of the accessories base 14 according to the invention, the accessories base 14 is designed and configured as a separate mountable/connectable unit for mounting/connecting to the instrument 10.

The dissecting device 34 is further designed and configured of a size and profile such that it will not interfere in passing the instrument 10 through a trocar 22 or other device that enables such passage when the dissecting device 34 is mounted on the accessories base 14.

Referring to FIG. 7, in another embodiment of the invention, an instrument or accessory according to the invention includes a multi-channel tip device 40 that is designed and configured to removably mount or connect to the accessories base 14. The accessories base 14 according to one embodiment of the invention may be integral with the instrument 10 along the distal end of the instrument 10. Alternatively, the accessories base 14 according to another embodiment of the invention may define a mountable/connectable unit that is mounted/connected to the instrument 10 along the distal end of the instrument 10. The multi-channel tip device 40 is constructed and arranged with a mounting or connection device and configuration for mounting/connecting to and removing from the accessories base 14. The multi-channel tip device 40 is further constructed and arranged to define multiple channels, e.g., two channels, substantially within its interior including, in one embodiment of the device 40 according to the invention, an optical fiber(s) or wave guide channel 42 and an accessory channel 44. The channel 42 facilitates passing of optical fiber(s) or a wave guide 16 through the instrument 10 in such a manner to enable the fiber(s) or wave guide 16 to deliver laser energy to the target tissue 54. The accessory channel 44 may be designed and configured to accept and to facilitate the positioning and/or passing of any of a variety of other instruments or accessories 48. For example, in some embodiments of the device 40 according to the invention, accessories 48 that the device 40 helps to position and/or pass to help to treat the target tissue 54 include, but are not limited to, other energy types (radio frequency and ultrasound energy), or a vacuum, or a fluid, or other media that help to treat the target tissue 54.
