Abstract
Description
- The present application is a continuation of U.S. patent application Ser. No. 14/613,010, filed Feb. 3, 2015, which claims the benefit of U.S. Provisional Application 61/935,227 (Attorney Docket No. 42369-707.101), filed on Feb. 3, 2014, the full disclosure of which is incorporated herein by reference in its entirety.
- 1. Field of the Invention. The present invention relates generally to medical devices and methods. More particularly, the present invention relates to surgical tool systems for endoscopic and laparoscopic procedures where a single tool shaft can be used with multiple surgical tool tips.
- Laparoscope and other endoscopic surgical procedures are widely used and have replaced many open surgical procedures. Laparoscopic procedures are performed within body cavities, such as the abdomen or thorax, and rely on introducing a shaft through a small incision, trocar or other access point through tissue which provide access into the cavity. In laparoscopic procedures, the shaft manipulates a tool or end effector to perform a surgical protocol while viewing the surgical field within the cavity using a camera. One drawback in performing laparoscopic and other endoscopic procedures is the need to frequently exchange tools through a limited number of access points.
- It has been proposed to increase the efficiency of laparoscopic and other endoscopic procedures by introducing a plurality of surgical tool tips into the surgical field, such as an insufflated abdomen or thorax, and subsequently exchanging tools on a single or limited number of tool shafts, thus avoiding the need to remove and exchange complete tools through the access points. Such surgical tools exchange systems and procedures are described, for example, in commonly owned U.S. Patent Publication No. 2013/0150871, the full disclosure which is incorporated herein by reference.
- 2. Background Art. U.S. Patent Publication 2013/0150871 has been described above. See also U.S. Pat. Nos. 5,925,002; 6,309,397; and 7,492,116; as well as U.S. Publication Nos. 2003/0114731; 2005/0043718; U.S. 2005/0209607; U.S. 2006/0041273; U.S. 2007/0198000; U.S. 2008/0108871; U.S. 2008/0147096; US. 2008/0167672; U.S. 2008/0275480; U.S. 2009/0005638; and U.S. 2013/0066304.
- In a first aspect, the present invention provides a surgical tool system comprising a surgical tool shaft having a distal end and proximal end. The surgical tool shaft includes a low power electrical interface, a high power electrical interface, and a mechanical interface. The system further comprises a plurality of surgical tools tips, wherein individual tool tips are detachably connectable to the distal end of the shaft. The individual tool tips will also include at least one of a low power electrical interface, a high power electrical interface, and a mechanical interface, wherein the interfaces on the tool tips are disposed on the tools so that they will mate with the corresponding interface on the shaft when the tool tip is mounted on the shaft. The low power electrical interface may provide power to sensors on the tool tip and/or receives data or other low power information from the tool tip. Alternatively, the low power electrical interface may provide control information to motors on the tool tip and/or receive control data or other low power information from the tool tip. The high power electrical interface will typically drive motors, power illumination, power cautery, power electrosurgical tools, or the like on the tool tip, while the mechanical interface will typically allow conventional grips, levers, or other manual drivers on the shaft or an associated handle to mechanically drive jaws, scissors, or the like on the tool tips.
- In a first embodiment, at least some of the surgical tool tips have sensors which connect to the low power electrical interface. Sensors may comprise temperature sensors, environmental sensors, diagnostics sensors, and the like. In the second embodiment, at least some of the surgical tool tips may have cameras which connect to the low power electrical interface. In a third embodiment, at least some of the surgical tool tips may have electrodes which connect to the high power electrical interface, such as radiofrequency electrodes for performing electrosurgery and/or electrocautery. The electrodes may also comprise resistance heaters, ablation elements, cutting elements, and the like. In a fourth embodiment, at least some of the surgical tool tips will comprise electrical motors which connect to the high power electrical interface and optionally to the low power electrical interface as well for control and other purposes. Electric motors can be connected to the high and/or the low power interface and may drive tools or may be connected to cameras for adjusting focus or magnification. In a sixth embodiment, the mechanical interface will provide linear actuation for a tool on the surgical tip, such as for driving scissors, forceps, or other pivoted elements. In an eighth embodiment the mechanical interface will provide rotational actuation to drive, for example, drills, burrs, abrading elements, and the like. In some arrangements, the mechanical interface may provide both rotational and linear actuation for selective connection to any of the end effectors described above for either or both rotational and linear actuation.
- In a second aspect of the present invention, a tool system comprises a surgical tool shaft have a distal and a proximal end. A surgical tool tip is detachably connectable to the distal end of the shaft, and the tool shaft includes a surface feature which mates with a lock mechanism on the tool tip so that rotation of the shaft relative to the tool tip releases the tip from the a holding member . For example, a shaft may have a cylindrical outer surface and the surface feature may comprise at least one flat face or facet on the cylindrical surface which engages a cam or other similar mechanism in the surgical tool tip to cause release of the tip from the holder.
- In a third aspect of the present invention, a tool tip cassette system comprises a tool carrier including a plurality of tool carrier segments at least some of which are connected with articulating joints. The terms “cassette” and “carrier” will be used interchangeably herein and in the claims. The cassette system further comprises a cassette manipulator including a handle and an attachment shaft. The shaft is configured to pass through tissue from an external location, typically through a cannula or a direct incision in the tissue, to a location in the body cavity. A distal end of the attachment shaft is configured to be detachably secured to the tool carrier while the tool carrier is within the body cavity. A handle is usually attached to the shaft at the external location and can be used to manipulate the tool carrier segments, for example by pulling the segments against an inner wall of a patient's thorax. Typically, the cassette manipulator will include a mechanism to selectively release the tool carrier from the shaft/or to selectively to release the manipulator from the shaft. In still other embodiments, the manipulator may provide mechanisms on the handle which allow the physician to reconfigure the tool carrier segments within the body cavity, for example, by straightening or bending the carrier segments, by releasing individual tool holders from each segments to make the circle tool tips accessible, or the like.

FIG. 1 illustrates a complete tool system with cassette. Thetool system 10 includes ahandle 12 andshaft 14. Acassette system 16 includes a plurality ofindividual segments 18 with articulatingjoints 20 anddeployable tool holders 22, each of which cradles a removable surgical tool tip 36 (FIG. 2 ). - The
tool system 10 is shown in more detail inFIG. 2 . Thehandle 12 includes ashaft rotator 26, afixed finger grip 28 and athumb actuator 30. Thehandle 12 typically house motors, controllers, and other components for driving and interfacing with theindividual tool tips 36. Thethumb actuator 30 will typically be connected to manipulate the tools in some desired way, for example, by mechanically opening and closing scissors, forceps, or other tool elements. Alternatively, the thumb actuator could actuate an electric motor to rotate the tool element, such as a burr, drill, or the like. Other features on the handle include atrocar button 32 and a trocar mode selector 34. - The
shaft 14 of the tool system will typically (but not necessarily) have a pointed, electro-surgical, or other tissue-penetrating tip to allow direct introduction through tissue, i.e. not through a previously placed cannula. While not necessary, such shafts with tissue-penetrating element could be introduced through cannulas or pre-formed incisions. - An exemplary
surgical tool tip 36 comprises a cassette-locking element, such aspawl 38, a printed circuit board or other low powerelectrical interface 40, and the like. A second or matinglow power interface 42 will typically be provided on theshaft 14 in order to interconnect with theinterface 40 on the tool. Thetool 36 itself may comprise mechanical elements such asjaws 46, although other mechanical and non-mechanical end effectors may also be provided, such as electrodes, drills, cameras, electrodes, and the like. -
FIG. 3 provides a detailed view of the distal end of the shaft entering thetool 36 while it is held within a deployedtool holder 22 which is part of thecassette system 16. The tool holder is raised from a bay in thesegment 18, and the distal end of theshaft 14, which is typically less than 3 mm in outside diameter, may be introduced into a larger or full sized tool tip, typically 8 mm, and thereafter may be locked onto the shaft, typically by the paw 38 (FIG. 2 ). -
FIG. 4A shows the distal end of theshaft 14 being introduced thesurgical tool tip 36 where a rotational motion can drive the tool, such as graspers, cutters, camera zoom/focus, morcellator, or the like. Rotational motion is converted by athrust bearing 48 wheresplines 50 on the tool tip engage a rotational mechanism to convert rotational motion into liner motion via alever 52. -
FIGS. 4B and 4C shows an alternative construction of thetool tip 36′ and the distal end ofshaft 14′ with a collet leaf 56 (retracted inFIG. 4B and exposed inFIG. 4C ) which is received into acollet leaf cavity 58 for locking and releasing the tool tip into a tool holder by canting latch element 60. Arotational alignment detent 62 is also provided.FIG. 4B shows theshaft 14′ prior to insertion intotool 36′, andFIG. 4C shows the shaft inserted into the tool. Details of the mechanism for locking and unlocking theshaft 14′ into thesurgical tool tip 36′ are provided inFIGS. 5A-4D . Exploded views are shown inFIGS. 5A and 5B where alock pin carrier 70 includes a trocar push offfeature 72,lock tip 74,spring 76 and spring caps 78.An unlocked configuration is shown inFIG. 5C and a locked configuration is shown inFIG. 5D . By rotating theshaft 14 through 90°, as indicated by the arrow inFIG. 5C , flat facets or surfaces on the cylindrical face of the distal end of theshaft 14 allow the lock pins 74 to drop under the force ofsprings 76, allowing the spring caps 78 to disengage the locking lever. -
FIG. 6 illustrates an exploded view of the connection of thehandle 12 of thetool system 10 to theshaft 14. Grounding pins 80 are movably received into grounding pin pockets 82, and ahandle collar 84 may be pushed forward to disengage the grounding pins or be pulled back to engage the grounding pins, thus allowing anose cone 86 to be selectively rotated. This allows the 90° rotation which is used for locking and unlocking the tool tip to the shaft of the device. -
FIG. 7 illustrates thetool system 10 andcassette system 16, where thecassette system 16 may be sutured in place with suture 90. -
FIGS. 7A-7C illustrate various configurations of thetool cassette system 16. A linear configuration is shown inFIG. 7A . The linear configuration is typically used for introducing the cassette into the patient. For thoracoscopic procedures, theindividual segments 18 andtools 36 may have non-circular cross sections in order to minimize the need to distract adjacent ribs for introduction. The tool cassettes are shown in their stable, curved configuration in 7B and further shown withindividual tool holders 22 deployed inFIG. 7C . - Referring now to
FIG. 8 , acassette manipulator 100 is shown attached to a center segment of a tool cassette deployed in the thorax of a patient. As better seen inFIGS. 9 and 10A-10B , thecassette manipulator 100 includes ahandle 102 and ashaft 104 where adistal tip 106 of the shaft can be detachably removed into acenter segment 108 of thetool cassette system 116. Thecenter segment 108 will typically not carry a tool and be provided as an interface for theshaft 104. After the tool cassette has been introduced into the thorax of the patient, as shown inFIG. 8 , theshaft 104 may be transcutaneously introduced, typically using the sharpened or otherwise tissue-penetratingtip 106, and then engaged into thesegment 108. Thehandle 102 can then be used to pull the cassette upwardly against the inner wall of the thorax, and the handle then ratcheted down against the outer skin of the patient in order to hold the tool cassette in place. At the end of the procedure, arelease button 120 can be pressed to release the cassette. Asecond release button 122 is provided to disengage the ratchet which holds the handle in place while a tip to the shaft. - While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.
