Definitions

  • This invention relates to improved surgical and cauterizing apparatus and methods for their use.
  • arthroscopic surgery is becoming increasingly popular, because it generally does less damage than open procedures, produces less scarring in and around joints, and results in faster healing and return of the patient to full productivity. Nevertheless, arthroscopic surgery has its limitations. The surgeon must operate through a narrow tube formed in the body on which surgery is being carried out, which is awkward. Only one probe can be used at a time for many operations. Often the viewing camera is positioned at an angle different from the surgeon's normal gaze. This contrasts with "open surgery” where the surgeon has relative ease of viewing the surgical site and can freely move both hands.
  • a surgeon will penetrate a vessel within the surgical site. At this point, the surgeon may desire to cauterize the vessel.
  • One way of cauterizing the vessel is the use of radio frequency (RF) energy, as described in U.S. Patent 5,100,402 to Fan.
  • RF radio frequency
  • Such RF methods offer a quick and relatively easy way of cauterizing penetrated vessels.
  • use of current RF cauterizing devices usually requires the surgeon to withdraw the surgical tool being used at the time, and insert a tool for cauterizing the penetrated vessel. This switching of the tools is usually required because of the space limitations involved in arthroscopic surgery. This switching of tools during surgery can be time consuming, awkward, and potentially dangerous to the patient. Additionally, there is the danger of not being able to locate the penetrated vessel. Therefore, there is the need for an improved surgical apparatus and cutting and cauterizing device and methods for using the apparatus and device to avoid the above-mentioned problems.
  • the invention relates to a surgical apparatus, comprising a surgical instrument including a housing and a cannula, and the cannula attached at a proximal end to the housing and defining at a distal end thereof an opening and the housing containing a drive interface; and a surgical tool including a shaft and a tip, and the tip located in the opening, and the shaft contained within the cannula and the shaft mechanically and electrically coupled at a distal end to the tip, and at a proximal end, to the drive interface and an electrical interface, and the drive interface producing a surgical motion of the tip, and the electrical interface producing a cauterizing action of the tip.
  • the invention in another aspect, relates to a cutting and cauterizing device for connection to a surgical instrument, and the surgical instrument including a drive interface and a first interconnector, and the cutting and cauterizing device comprising a cannula defining at a distal end thereof an opening; a second interconnector, suitable for switchably coupling to a power supply, and the second interconnector located at the proximal end of the cannula and shaped to couple to the first interconnector; and a surgical tool including a shaft and a tip, and the tip located in the opening, and the shaft contained within the canula, and the shaft coupled at a distal end to the tip and at a proximal end mechanically coupled to the drive interface to permit a surgical motion of the tip, and electrically coupled to the second interconnector to permit a cauterizing action of the tip.

ELECTRO-SURGICAL CUTTING AND CAUTERIZING TOOL
BACKGROUND OF THF, INVENTION
Field of the Invention
This invention relates to improved surgical and cauterizing apparatus and methods for their use.
Description of Related Art
Arthroscopic surgery is becoming increasingly popular, because it generally does less damage than open procedures, produces less scarring in and around joints, and results in faster healing and return of the patient to full productivity. Nevertheless, arthroscopic surgery has its limitations. The surgeon must operate through a narrow tube formed in the body on which surgery is being carried out, which is awkward. Only one probe can be used at a time for many operations. Often the viewing camera is positioned at an angle different from the surgeon's normal gaze. This contrasts with "open surgery" where the surgeon has relative ease of viewing the surgical site and can freely move both hands.
Occasionally, during the performance of an arthroscopic or similar minimally invasive procedure, a surgeon will penetrate a vessel within the surgical site. At this point, the surgeon may desire to cauterize the vessel. One way of cauterizing the vessel is the use of radio frequency (RF) energy, as described in U.S. Patent 5,100,402 to Fan. Such RF methods offer a quick and relatively easy way of cauterizing penetrated vessels. However, use of current RF cauterizing devices usually requires the surgeon to withdraw the surgical tool being used at the time, and insert a tool for cauterizing the penetrated vessel. This switching of the tools is usually required because of the space limitations involved in arthroscopic surgery. This switching of tools during surgery can be time consuming, awkward, and potentially dangerous to the patient. Additionally, there is the danger of not being able to locate the penetrated vessel. Therefore, there is the need for an improved surgical apparatus and cutting and cauterizing device and methods for using the apparatus and device to avoid the above-mentioned problems.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1A shows an isometric view of surgical apparatus 100, including surgical tool 102 and surgical instrument 110. Surgical instrument 110 includes housing 108, power cord 106, and interconnector 112. Housing 108 also includes push switch 116, electrical contact 118, spring 120, wire 122, and drive interface 132. Surgical tool 102 includes drive coupling 130, commutator 134, shaft 140, and tip 142. Surgical tool 102 additionally includes cannula 114, and opening 138.
Surgical instrument 110 includes housing 108, attached at a distal end, via interconnector 112, to a proximal end of cannula 114. The distal end of cannula 114 defines an opening 138. Shaft 140 is contained within cannula 114.
Tip 142 is at the distal end of shaft 140 and protrudes through opening 138 at distal end of cannula 114. At the proximal end of shaft 140 are located commutator 134, and drive coupling 130. Located within housing 108 is drive interface 132, located adjacent to drive coupling 130. Power cord 106 enters housing 108 at a proximal end. Power cord 106 electrically couples to electrical contact 118 via wire 122. Push switch 116 is located on housing 108. The push switch is connected to electrical contact 118. The electrical contact is aligned with commutator 134. Spring 120 biases electrical contact 118 away from the commutator.
In operation, drive interface 132 engages drive coupling 130 to produce surgical motion of tip 142. which is transmitted by shaft 140. Push switch 116 may be depressed against spring 120 to create an electrical contact between electrical contact 118 and commutator 134. This closes a circuit between the power supplied through power cord 106 and wire 122 through shaft 140 to tip 142, thereby producing a cauterizing action at the tip 142. It should be noted that the surgical motion in any of the embodiments of this invention, can be, for example, rotary, reciprocal, rotary-reciprocal, etc. The shaft and cannula can be straight, or can include an arcuate section. In those instances where the surgical tool contains an arcuate section, the shaft may contain a flexible section to accommodate the motion of the shaft. FIG. IB shows another isometric view of a different embodiment of the invention, wherein the use of a removable interconnector allows the surgical tool to be removed from the housing. FIG. IB shows surgical apparatus 100, which includes surgical instrument 110, and surgical tool 102. Surgical instrument 110 includes housing 108.

Cannula 114 is connected at a proximal end to interconnector 112. The interconnector may be removably connected to a distal end of housing 108. Distal end of cannula 114 defines opening 138. Shaft 140 is contained within the cannula and has at its distal end tip 142, which protrudes through opening 138 in the cannula. The proximal end of the shaft extends into the housing.
Drive coupling 130 is affixed to the proximal end of the shaft. The drive coupling and the proximal end of the shaft are contained within the housing.
Power cord 106 is connected to a proximal end of the housing. Also within the housing is a drive interface 132, positioned adjacent to the drive coupling. Wire
122 is removably attached to the exterior of the housing. The wire is used to connect a power supply to the interconnector.
In operation, drive interface 132 is energized by power cord 106, and engages drive coupling 130 to produce a surgical motion of tip 142, which is transmitted via shaft 140. Electrical power is supplied via wire 122 to interconnector 112 to tip 142, via shaft 140, so as to produce a cauterizing action at tip 142. The design of the interconnector allows the surgical tool to be removed from the housing.
FIGS. 2A-B are enlarged cross-sectional views of interconnector 112. In FIGS. 2A-B, an embodiment of the invention is shown in which the interconnector is removable from housing 108 as shown in FIG. IB. FIG. 2A shows such an embodiment, where shaft 140 is generally conducting, while FIG.
2B shows such an embodiment where the shaft is generally non-conducting, but has an interior conductor 240. FIG. 2A shows surgical apparatus 200, which includes housing 108, and interconnector 112. The housing includes extended housing portion 208.
Interconnector 112 includes outer O-ring seal 206, locking member 216, interconnector conductor 250, electrical connector 252, and locking ring 218.
Also shown are cannula 114, inner alignment piece 230, and shaft 140, drive coupling 130, commutator 260. Furthermore, drive interface 132 is shown.
Shaft 140 is contained within cannula 114, and kept separate from the cannula by inner alignment piece 230. The cannula, inner alignment piece , and shaft are connected at their proximal ends to housing 108 via interconnector
112. Interconnector 112 serves to locate the shaft, inner alignment piece, and cannula. Interconnector 112 includes locking member 216 which is shaped so as to secure the cannula within extended housing portion 208. The locking member also has a notch 212, which is located opposite a detent 210 located on an interior surface of the extended housing portion.

The electrical connector is located such that it is in electrical connector with commutator 260.
In operation, interconnector 112 serves to attach inner alignment piece 230, shaft 140 and cannula 114 to the housing. The inner alignment piece serves to locate the shaft within the cannula, and also serves as a bearing for the shaft. Locking member 216 serves to locate the inner alignment piece within extended housing portion 208 through the engagement of notch 212 on the locking member and detent 210 on the interior of the extended housing portion. Locking ring 218 serves to secure the locking member, together with the cannula, inner alignment piece and shaft, within the extended housing portion. The locking ring accomplishes this via the cooperative action of its interior threads 214B and exterior threads 214A, which are located on the exterior surface of the extended housing portion. Drive coupling 130 serves to impart a surgical motion to shaft 140. Outer O-ring seal 206 serves to prevent transmission of body fluids that may be present at the distal end of the shaft through to the housing. Electrical power is provided via wire 122, to commutator 260. Commutator 260 is electrically coupled to distal end of shaft
140, thus producing a cauterizing effect at the distal end of the shaft.
