Definitions
- This invention relates to packages for surgical devices, and particularly to packages for removable tips of such devices.
- Examples of surgical devices with removable tips include electrosurgical devices, such as monopolar cauterization devices and diathermy devices.
- electrosurgical devices such as monopolar cauterization devices and diathermy devices.
- Other types of removable tips are sharp tips (e.g., needles, pics, and blades) that are attached to the end of a handle.
- This invention features a package for a surgical device tip which may be used for insertion of the tip onto and removal of the tip from the handle of the surgical device, without requiring any direct contact between the user's hand and the tip.
- a package for a tip of a surgical device capable of removable attachment to an end of a handle includes a housing having a tip cavity shaped to receive the tip and an opening through which the end of the handle is insertable for removable attachment to the tip.
- Related aspects of the invention feature the combination of the package and a tip disposed in the package, and methods of using the package to attach the tip onto, and detach the tip from, the handle.
- Preferred embodiments may include one or more of the following features.
- a releasable locking mechanism which is released in response to the end of the handle being disposed in the opening for removable attachment to the tip, retains the tip in the tip cavity.
- the releasable locking mechanism is a movable protrusion of an inner surface of the housing which forms the cavity, and is movable by the end of the handle to release the tip.
- the package is made from a single piece of molded material, which may be a clear plastic material such as co-polyester PETG or polyvinyl chloride.
- the package is made by molding, such as vacuum molding.
- the package in another general aspect of the invention, includes a top portion, a bottom portion, and a hinging segment connecting the top portion and the bottom portion.
- the top portion and the bottom portion form a tip cavity when the top portion and the bottom portion are folded together along the hinging segment.
- the tip cavity is shaped to receive the tip and has an opening through which the end of the handle is insertable for removable attachment to the tip.
- Preferred embodiments may also include one or more of the following features.
- a releasable locking mechanism including a releasable locking recess formed in the top portion and the bottom portion, holds the tip within the tip cavity.
- the locking mechanism is releasable in response to the end of the handle being disposed in the opening for removable attachment to the tip.
- the tip includes a protrusion, and the top portion includes a positioning cavity shaped to receive the protrusion to prevent the tip from rotating within the tip cavity.
- the end of the handle has a bevel, and the locking mechanism has a ramp disposed adjacent to the locking recess so that the bevel contacts the ramp to release the locking mechanism.
- the top and bottom portions include several molded features.
- the top portion includes a molded packet and the bottom portion includes a molded boss, the boss engaging the pocket to hold the top portion and the bottom portion together when folded along the hinging segment.
- the top and bottom portions also include interlocking ribs.
- the top portion includes a molded placement indicator to indicate placement of a user's fingers, and a molded directional indicator to indicate a direction of movement of the handle in the tip cavity.
- a tip disposed within the package is attached to the end of a handle by inserting the end of the handle into the package opening to release the tip, pushing the end of the handle inserted into the opening to attachably engage the tip to the end of the handle, and withdrawing the end of the handle from the opening with the attachably engaged tip.
- the tip is detached from the handle and stored in the package by inserting the end of the handle with the removably attached tip into the package opening, pushing the end of the handle inserted into the opening until the tip is released and retained in the package, and withdrawing the end of the handle from the opening. Pressure may be applied to and released from the package to assist in the attachment of the tip onto and the removal of the tip from the handle.
- the invention is particularly well-suited, but by no means limited, for use with bipolar electrosurgical devices with removable bipolar tips which can be easily and conveniently detached from the handle, such as the devices disclosed in the parent application.
- the tip is attachable to a handle having an opening and a plurality of coaxial, axially spaced electrical contacts.
- the tip includes a tip housing having a proximal end and a distal end, the proximal end of the tip housing configured to be received within the opening of the handle.
- a plurality of electrodes are disposed through the tip housing, the electrodes having distal ends that extend distally from the distal end of the tip housing and proximal ends that are coaxial and axially spaced from each other and that extend proximally from the proximal end of the tip housing for connection to the coaxial, axially spaced electrical contacts of the handle when the proximal end of the tip housing is inserted in the opening of the handle.
- the proximal end of the tip housing is constructed to be releasably secured to the handle (e.g., by a snap fit) for operation of the surgical device solely by inserting the proximal end of the tip housing axially into the opening of the handle.
- the package has a tip cavity shaped to receive the tip.
- the tip is a sharp tip.
- the user simply selects a packaged tip from an inventory of such tips, and installs the tip onto the device handle in the manner described above.
- the device is then ready for use in surgery.
- the tip is removed from the handle and stored in the package, using the procedure described above, and discarded or stored for subsequent use during the same surgical procedure.
- another packaged tip may be selected, inserted onto the handle, and used to perform a different treatment (e.g., cauterization) during the same surgical procedure.
- the package securely retains and protects each tip, thereby eliminating several safety and sterility concerns that accompany the use of removable surgical tips.
- the package eliminates the need for the user's hand to contact the tips during either installation or removal of the tips.
- Use of the package prevents contamination or exposure by the user to used tips.
- tips delivered in sterile packages can be attached to the handle without risking contamination from the user's hands.
- the package allows for simple insertion of tips onto and removal of tips from the handle of the surgical device.
- the package may be shaped to accommodate various types of tips used with the handle.
- the package which may permit the user to see the tip inside, allows for efficient organization of tips during a surgical procedure.
- the package also protects the user from the sharp ends of the tips' electrodes.
- the interlocking ribs of the top and bottom portions and the hinging segment help to avoid accidental release of the tip retained in the package and to prevent the sharp end of the tip electrode from sliding out through the sides of the package.
- the electrical contacts of the tip electrodes that attach to the handle are recessed in the opening of the housing to avoid accidental contact with the user's hands.

- a surgical device 10 has a reusable handle 12 with a removable tip 14 .
- tip 14 is inserted into handle 12 as shown in FIGS. 3 and 4.
- tip 14 is removed from handle 12 , discarded, and a new tip is inserted into handle 12 .
- Tip 14 comprises a solid, cylindrical inner electrode 16 disposed coaxially inside a hollow, cylindrical cuter electrode 18 . Electrodes 16 , 18 are closely spaced and separated by a thin coaxial insulator 20 . Alternatively, tip 14 may be made by coating outer electrode 18 onto an insulated inner electrode 16 , as described in the copending patent application of Harry Reimels et al. entitled “Bipolar Electrosurgical Instrument and Method for Making the Same,” filed Jan. 26, 1996 as Ser. No. 63/591,953, assigned to the present assignee and incorporated herein by reference.
- a distal treatment end 22 of the electrodes includes a flat surface 24 that is applied to tissue during surgery.
- a proximal connection end 25 of the electrodes is configured for connection to handle 12 .
- Electrodes 16 , 18 form a substantially straight line from connection end 25 to treatment end 22 .
- a proximal end 17 of inner electrode 16 is axially displaced from a proximal end 19 of outer electrode 18 .
- a proximal end 21 of insulator 20 is disposed intermediate the proximal ends 17 , 19 of electrodes 16 , 18 .
- a length (a) of electrode 18 , a length (b) of insulator 20 and a length (c) of electrode 16 are exposed (FIG. 2).
- Handle 12 includes an opening 56 at one end.
- the end of handle 12 also has a sloped bevel 57 , the width of which increases as the distance to opening 56 increases.
- Two cylindrical electrical contacts 74 , 76 separated by cylindrical receptacle 78 are arranged coaxially in opening 56 .
- Contact 74 has one end 82 abutting an end of receptacle 78 .
- Another end of receptacle 78 is adjacent to an end of contact 76 .
- Contact 76 has a smaller radius than contact 74
- receptacle 78 has a radius intermediate those of contacts 74 , 76 .
- the length of contact 74 matches the combined lengths of outer electrode 18 and insulator 20 at connection end 25 (i.e. length a +length b in FIG. 2).
- the length of receptacle 78 and contact 76 together equal the length (c) of electrode 16 exposed at tip end 25 .
- a ring-like conductor 75 , 77 is disposed on the inside surface of each electrical contact 74 , 76 .
- the inner diameter of conductors 75 , 77 is only slightly larger than the diameter of electrodes 18 , 16 , respectively.
- each contact 74 , 76 is connected by a wire 84 , 86 to a connector pin 88 , 90 at a proximal end of handle 12 .
- Pins 88 , 90 are adapted for connection to a high frequency power source.
- Tip 14 also includes a plastic housing 28 mounted around the exterior of electrode 18 .
- Treatment end 22 and connection end 25 of electrodes 16 , 18 extend distally and proximally, respectively, from housing 28 .
- the distal end of housing 28 is conically shaped and has a sloping, grooved exterior surface 30 .
- a proximal end of housing 14 comprises a conical section 32 that terminates in a cylindrically-shaped nose 34 .
- the shape of handle opening 56 is complementary to that of the proximal end of housing 28 so that housing 28 snugly mates with handle 12 .
- the distal end of opening 56 includes a conically-shaped inner surface 70 that meets a cylindrically-shaped inner surface 72 .
- Handle 12 is formed as a cylindrical body 50 (made from, e.g. metal or composite material) with a distal section 54 that is threaded onto a proximal section 55 . Opening 56 is disposed in distal section 54 , while proximal section 55 includes the electrical contacts 74 , 76 , receptacle 78 , wires 82 , 86 and pins 88 , 90 .
- a series of grooves 52 is formed in the exterior surface of proximal section 55 to define a set of raised circumferential ribs 53 that assist the user in gripping the device.
- tip 14 includes a protrusion 38 extending from grooved surface 30 to an edge of tapered section 32 , at a predetermined radial position with respect to electrodes 16 , 18 .
- Protrusion 38 has an axially-extending rectangular tab 40 that terminates proximally in a round button 42 .
- the diameter of button 42 is slightly larger than the width of tab 40 .
- Distal end 54 of handle 14 includes an axially-extending, tapered slot 58 that communicates with opening 56 .
- the proximal end 59 of slot 58 meets a round opening 60 that is only slightly larger than button 42 on tip 14 .
- the diameter of round opening 60 slightly exceeds the width of slot 58 at end 59 .
- FIGS. 6 A- 6 E show an inventory of tips 14 compatible with handle 12 .
- Treatment ends 22 of tips 14 have a variety of configurations.
- some tips 14 have treatment ends with a flat distal surface 24 (e.g., treatment end 22 ) which may be beveled (e.g., treatment end 22 3 ), while others tips 14 have a concave distal surface 24 (e.g., end 22 4 ).
- Still other tips 14 in the inventory have treatment ends that are tapered to a fine point (e.g., treatment end 22 10 ), to a round, blunt distal surface 24 (e.g., treatment end 22 6 ) or to a flat surface (e.g., end 22 5 ).
- the treatment ends of some tips form a straight line from housing 28 to surface 24 (e.g., end 22 ), while others include a bend of 30 °, 45 °, or 90 ° (e.g., ends 22 7 , 22 6 , 22 9 , respectively).
- Another type of tip 14 includes a treatment end 22 13 with two bends, appropriate for performing a capsulotomy.
- a user selects a tip 14 from the inventory and inserts the selected tip 14 into handle 12 simply by aligning protrusion 38 on housing 28 with slot 58 in handle 12 and inserting connection end 25 of tip 14 into handle opening 56 .
- the proximal end of housing 12 enters handle opening 56 , and protrusion 38 slides into slot 58 .
- button 42 of protrusion 38 enters round opening 60
- end 59 of slot 58 expands.
- end 59 of slot 58 snaps back to its original size to hold button 42 firmly in opening 60 .
- the exterior surfaces of housing sections 32 , 34 also frictionally engage inner surfaces 70 , 72 of opening 56 . Tip 14 is thus held in handle 12 by a friction fit as well as by a snap fit.
- outer electrode 18 and insulator 20 enter contact 76 , and outer electrode 18 firmly contacts conductor 75 .
- inner electrode 16 slides into contact 74 and receptacle 78 , and proximal end 17 of electrode 16 engages conductor 77 . Friction between the adjacent surfaces of electrodes 16 , 18 and conductors 77 , 75 provides a reliable, secure electrical connection, and also helps avoid tip 14 disengaging from handle 12 .
- the user connects device 10 to a high frequency power source 150 by connecting a standard socket 152 on a cable 153 to connector pins 88 , 90 .
- Power source 150 provides electrical power to contacts 74 , 76 via pins 88 , 90 , which in turn provide the power to electrodes 16 , 18 (FIG. 1).
- Holding body 50 of handle 12 and housing 28 of tip 14 the user places surface 24 of electrodes 16 , 18 on tissue 154 to be treated, e.g., within the eye.
- the voltage applied by electrodes 16 , 18 induces a high frequency current in the tissue, thereby performing cauterization, coagulation, or other surgical operations.
- tip 14 After use, the user detaches tip 14 from handle 12 by pulling tip 14 axially out of opening 56 . Protrusion 38 on tip 14 forces edges 59 of slot 58 outward as button 42 is pulled through slot 58 . The user discards tip 14 , and sterilizes handle 12 (e.g., by autoclaving) for subsequent use.
- the user selects a new tip from the inventory of tips. For example, the user may choose tip 14 with treatment end 22 1 , shown in FIG. 7. The user then inserts the new tip in handle 12 , as described above, and performs a new surgical procedure.
- tip 14 would be made from reusable material capable of, e.g., withstanding autoclaving.
- Proximal section 55 and distal section 54 of handle 12 may also be combined into a unitary, molded body.
- the handle and tip may have other shapes:
- surgical device 100 has a non-cylindrical handle 112 that axially tapers between relatively large diameter regions 112 a , 112 c and smaller waist regions 112 b , 112 d .
- This contoured shape fits comfortably in the user's hand.
- narrow waist region 112 d can be gripped between the user's fingers to assist in precisely treatment end 122 of tip 114 in the body.
- the housing 128 of tip 114 is hourglass-shaped, tapering from a relatively wide proximal region 129 to a narrow intermediate waist 130 , and then to a somewhat larger-diameter distal region 131 . With this shape, housing 128 fits securely in the user's hand (with waist 130 being gripped between the user's fingers) when inserting tip 114 into and removing tip 114 from handle 112 . Both handle 112 arid tip housing 128 may be ribbed 133 to further enhance gripping.
- tip 14 (or tip 114 ) may be delivered in a reinforced, sterile “blister” package 200 which allows for easy insertion of the tip onto handle 12 arid removal of the tip from the handle, without any direct contact between the user's hand and the tip.
- Package 200 can be sterilized and sealed within a sterile pouch (not shown) for use during surgery.
- Package 200 containing tip 14 may also be sterilized after insertion in the sterile pouch preferably using ethylene oxide (ETO) or gamma rays.
- ETO ethylene oxide
- Package 200 is made from a single piece of thin, flexible plastic material, preferably 0.015 inch thick Kodak “Kodar” 6763 clear co-polyester medical PETG. Another material that may be used for package 200 is polyvinyl chloride. Package 200 is preferably made by vacuum molding the plastic material. Other methods of making package 200 include injection molding and pressure or vacuum thermoforming of the plastic material.
- package 200 includes a top portion 205 and a bottom portion 206 connected by a rigid hinging segment 207 .
- Hinging segment 207 includes two hinging points 207 a which create a blunt shelf 207 b , and two walls 207 c which provide rigidity for the hinging segment.
- Package 200 is folded into a closed position by folding top portion 205 and bottom portion 206 toward each other along hinging segment 207 , and forming the hinging segment itself by folding along hinging points 207 a .
- FIGS. 9 and 10 show package 200 prior to folding
- FIGS. 11 - 14 show the package with the top and bottom portions folded together.
- molded top portion 205 and molded bottom portion 206 form a cavity 220 shaped to receive the entire tip 14 .
- Top portion 205 and bottom portion 206 both include flat surfaces 262 and 264 that substantially meet each other when package 200 is folded together.
- Cavity 220 may be shaped to accept, discharge and protect all types of shapes of tips that are used with handle 12 (e.g., the tips shown in FIGS. 6 A- 6 E).
- Cavity 220 includes an upper chamber 224 and a lower chamber 226 .
- Cavity 220 is also shaped to receive the conically shaped housing 28 of tip 14 , including sloping, grooved exterior surface 30 .
- Cavity 220 has an opening 222 into lower chamber 226 that is large enough only to receive the end of handle 12 for inserting tip 14 onto and removing the tip from the handle.
- the electrical contacts of the tip electrodes which extend from tip 14 and attach to handle 12 are recessed within opening 222 to avoid accidental contact with the user's hands.
- Upper chamber 224 is formed by molded sections 208 and 209 in top portion 205 and bottom portion 206 , respectively, when the top and bottom portions are folded toward each other. Upper chamber 224 is large enough to accommodate the electrodes of both straight and bent tips, such as the tips shown in FIGS. 6 A- 6 E.
- Housing 28 of tip 14 is securely held and properly oriented in package 200 within lower chamber 226 .

- the user grasps package 200 between double arrows 242 with his or her fingers to apply pressure to hold tip 14 within cavity 220 .
- Tip 14 is then separated from handle 12 -by pulling the handle away from the tip. As the user withdraws handle 12 from opening 222 , the interface between tip 14 and handle 12 separates, and handle 12 moves down ramps 203 , 203 a allowing locking recesses 202 , 202 a to recede radially inward toward central axis 260 and recapture tip 14 . Tip 14 , securely held within its package 200 , may then be discarded or stored for subsequent use during the same surgical procedure.
- each tip provides the user with efficient access to a variety of different tips during surgery. Since a tip may be used several times for the same patient during a single surgical procedure, the tips used with the patient may be efficiently stored in their packages during the surgical procedure, without contamination due to handling by the user. The return of the tips to their packages during a surgical procedure allows for minimal disposal and waste of tips. Further, by placing each tip into its package after it is used during a surgical procedure, a variety of tips used with a single handle during the surgical procedure may be efficiently organized.
- package 200 allows the user to remove used tips from the handle in a simple fashion and without direct contact between the tips and the user's hand.
- patient-contaminated tips may be safely manipulated and stored during surgery and disposed of after surgery.
- use of the package to insert tips onto and remove tips from the handle decreases the risk of puncturing hazardous waste bags and infecting the user or clinical staff.

Abstract
A package for a tip, such as a replaceable tip for a bipolar electrosurgical device, is used for insertion of the tip onto and removal of the tip from the end of a device handle, without requiring any direct contact between the user's hand and the tip. The package includes a housing having a tip cavity shaped to receive the tip and an opening through which the end of the handle is insertable for removable attachment to the tip. A releasable locking mechanism, which is releasable in response to the end of the handle being disposed in the opening for removable attachment to the tip, retains the tip in the tip cavity. The package may be made from a single piece of molded material, such as a clear plastic. The package may also be used with monopolar, diathermized and non-bipolar tips, as well as other sharp tips such as cannulae, pics and blades, that are attachable to the end of a handle.
Description
- This is a continuation-in-part of application Ser. No. 08/709,181, filed Sep. 6, 1996 (the “parent application”).
- This invention relates to packages for surgical devices, and particularly to packages for removable tips of such devices.
- Examples of surgical devices with removable tips include electrosurgical devices, such as monopolar cauterization devices and diathermy devices. Other types of removable tips are sharp tips (e.g., needles, pics, and blades) that are attached to the end of a handle.
- This invention features a package for a surgical device tip which may be used for insertion of the tip onto and removal of the tip from the handle of the surgical device, without requiring any direct contact between the user's hand and the tip.
- In one general aspect of the invention, a package for a tip of a surgical device capable of removable attachment to an end of a handle includes a housing having a tip cavity shaped to receive the tip and an opening through which the end of the handle is insertable for removable attachment to the tip. Related aspects of the invention feature the combination of the package and a tip disposed in the package, and methods of using the package to attach the tip onto, and detach the tip from, the handle.
- Preferred embodiments may include one or more of the following features.
- A releasable locking mechanism, which is released in response to the end of the handle being disposed in the opening for removable attachment to the tip, retains the tip in the tip cavity. The releasable locking mechanism is a movable protrusion of an inner surface of the housing which forms the cavity, and is movable by the end of the handle to release the tip.
- The package is made from a single piece of molded material, which may be a clear plastic material such as co-polyester PETG or polyvinyl chloride. The package is made by molding, such as vacuum molding.
- In another general aspect of the invention, the package includes a top portion, a bottom portion, and a hinging segment connecting the top portion and the bottom portion. The top portion and the bottom portion form a tip cavity when the top portion and the bottom portion are folded together along the hinging segment. The tip cavity is shaped to receive the tip and has an opening through which the end of the handle is insertable for removable attachment to the tip.
- Preferred embodiments may also include one or more of the following features.
- A releasable locking mechanism, including a releasable locking recess formed in the top portion and the bottom portion, holds the tip within the tip cavity. The locking mechanism is releasable in response to the end of the handle being disposed in the opening for removable attachment to the tip.
- The tip includes a protrusion, and the top portion includes a positioning cavity shaped to receive the protrusion to prevent the tip from rotating within the tip cavity. The end of the handle has a bevel, and the locking mechanism has a ramp disposed adjacent to the locking recess so that the bevel contacts the ramp to release the locking mechanism.
- The top and bottom portions include several molded features. For example, the top portion includes a molded packet and the bottom portion includes a molded boss, the boss engaging the pocket to hold the top portion and the bottom portion together when folded along the hinging segment. The top and bottom portions also include interlocking ribs. The top portion includes a molded placement indicator to indicate placement of a user's fingers, and a molded directional indicator to indicate a direction of movement of the handle in the tip cavity.
- In use, a tip disposed within the package is attached to the end of a handle by inserting the end of the handle into the package opening to release the tip, pushing the end of the handle inserted into the opening to attachably engage the tip to the end of the handle, and withdrawing the end of the handle from the opening with the attachably engaged tip. Similarly, the tip is detached from the handle and stored in the package by inserting the end of the handle with the removably attached tip into the package opening, pushing the end of the handle inserted into the opening until the tip is released and retained in the package, and withdrawing the end of the handle from the opening. Pressure may be applied to and released from the package to assist in the attachment of the tip onto and the removal of the tip from the handle.
- The invention is particularly well-suited, but by no means limited, for use with bipolar electrosurgical devices with removable bipolar tips which can be easily and conveniently detached from the handle, such as the devices disclosed in the parent application.
- Thus, in one embodiment, the tip is attachable to a handle having an opening and a plurality of coaxial, axially spaced electrical contacts. The tip includes a tip housing having a proximal end and a distal end, the proximal end of the tip housing configured to be received within the opening of the handle. A plurality of electrodes are disposed through the tip housing, the electrodes having distal ends that extend distally from the distal end of the tip housing and proximal ends that are coaxial and axially spaced from each other and that extend proximally from the proximal end of the tip housing for connection to the coaxial, axially spaced electrical contacts of the handle when the proximal end of the tip housing is inserted in the opening of the handle. The proximal end of the tip housing is constructed to be releasably secured to the handle (e.g., by a snap fit) for operation of the surgical device solely by inserting the proximal end of the tip housing axially into the opening of the handle. The package has a tip cavity shaped to receive the tip. In an alternative embodiment, the tip is a sharp tip.
- In use, the user simply selects a packaged tip from an inventory of such tips, and installs the tip onto the device handle in the manner described above. The device is then ready for use in surgery. After it is used, the tip is removed from the handle and stored in the package, using the procedure described above, and discarded or stored for subsequent use during the same surgical procedure. If desired, another packaged tip may be selected, inserted onto the handle, and used to perform a different treatment (e.g., cauterization) during the same surgical procedure.
- The package securely retains and protects each tip, thereby eliminating several safety and sterility concerns that accompany the use of removable surgical tips. Among other advantages, the package eliminates the need for the user's hand to contact the tips during either installation or removal of the tips. Use of the package prevents contamination or exposure by the user to used tips. Further, tips delivered in sterile packages can be attached to the handle without risking contamination from the user's hands.
- The package allows for simple insertion of tips onto and removal of tips from the handle of the surgical device. The package may be shaped to accommodate various types of tips used with the handle. The package, which may permit the user to see the tip inside, allows for efficient organization of tips during a surgical procedure.
- The package also protects the user from the sharp ends of the tips' electrodes. The interlocking ribs of the top and bottom portions and the hinging segment help to avoid accidental release of the tip retained in the package and to prevent the sharp end of the tip electrode from sliding out through the sides of the package. Also, the electrical contacts of the tip electrodes that attach to the handle are recessed in the opening of the housing to avoid accidental contact with the user's hands.

- Before describing the package of the present invention, it would be helpful to describe one kind of surgical instrument with which the package may be used. Referring to FIGS. 1 and 2, a
surgical device 10 has areusable handle 12 with aremovable tip 14. In use,tip 14 is inserted intohandle 12 as shown in FIGS. 3 and 4. After use,tip 14 is removed fromhandle 12, discarded, and a new tip is inserted intohandle 12. -
Tip 14 comprises a solid, cylindricalinner electrode 16 disposed coaxially inside a hollow, cylindricalcuter electrode 18.Electrodes coaxial insulator 20. Alternatively,tip 14 may be made by coatingouter electrode 18 onto an insulatedinner electrode 16, as described in the copending patent application of Harry Reimels et al. entitled “Bipolar Electrosurgical Instrument and Method for Making the Same,” filed Jan. 26, 1996 as Ser. No. 63/591,953, assigned to the present assignee and incorporated herein by reference. - A
distal treatment end 22 of the electrodes includes aflat surface 24 that is applied to tissue during surgery. Aproximal connection end 25 of the electrodes is configured for connection to handle 12.Electrodes connection end 25 totreatment end 22. - At
connection end 25, aproximal end 17 ofinner electrode 16 is axially displaced from aproximal end 19 ofouter electrode 18. Aproximal end 21 ofinsulator 20 is disposed intermediate the proximal ends 17, 19 ofelectrodes electrode 18, a length (b) ofinsulator 20 and a length (c) ofelectrode 16 are exposed (FIG. 2). -
Handle 12 includes anopening 56 at one end. The end ofhandle 12 also has a slopedbevel 57, the width of which increases as the distance to opening 56 increases. Two cylindricalelectrical contacts cylindrical receptacle 78 are arranged coaxially inopening 56.Contact 74 has oneend 82 abutting an end ofreceptacle 78. Another end ofreceptacle 78 is adjacent to an end ofcontact 76.Contact 76 has a smaller radius thancontact 74, andreceptacle 78 has a radius intermediate those ofcontacts - The length of
contact 74 matches the combined lengths ofouter electrode 18 andinsulator 20 at connection end 25 (i.e. length a +length b in FIG. 2). The length ofreceptacle 78 andcontact 76 together equal the length (c) ofelectrode 16 exposed attip end 25. - A ring-
like conductor electrical contact conductors electrodes contact wire connector pin handle 12.Pins -
Tip 14 also includes aplastic housing 28 mounted around the exterior ofelectrode 18.Treatment end 22 and connection end 25 ofelectrodes housing 28. The distal end ofhousing 28 is conically shaped and has a sloping,grooved exterior surface 30. A proximal end ofhousing 14 comprises aconical section 32 that terminates in a cylindrically-shapednose 34. The shape ofhandle opening 56 is complementary to that of the proximal end ofhousing 28 so thathousing 28 snugly mates withhandle 12. Thus, the distal end of opening 56 includes a conically-shapedinner surface 70 that meets a cylindrically-shapedinner surface 72. -
Handle 12 is formed as a cylindrical body 50 (made from, e.g. metal or composite material) with adistal section 54 that is threaded onto aproximal section 55.Opening 56 is disposed indistal section 54, whileproximal section 55 includes theelectrical contacts receptacle 78,wires grooves 52 is formed in the exterior surface ofproximal section 55 to define a set of raisedcircumferential ribs 53 that assist the user in gripping the device. - Referring also to FIG. 5,
tip 14 includes aprotrusion 38 extending from groovedsurface 30 to an edge of taperedsection 32, at a predetermined radial position with respect toelectrodes Protrusion 38 has an axially-extendingrectangular tab 40 that terminates proximally in around button 42. The diameter ofbutton 42 is slightly larger than the width oftab 40. -
Distal end 54 ofhandle 14 includes an axially-extending, taperedslot 58 that communicates withopening 56. Theproximal end 59 ofslot 58 meets around opening 60 that is only slightly larger thanbutton 42 ontip 14. The diameter ofround opening 60 slightly exceeds the width ofslot 58 atend 59. - FIGS.6A-6E show an inventory of
tips 14 compatible withhandle 12. Treatment ends 22 oftips 14 have a variety of configurations. For example, sometips 14 have treatment ends with a flat distal surface 24 (e.g., treatment end 22) which may be beveled (e.g., treatment end 22 3), whileothers tips 14 have a concave distal surface 24 (e.g., end 22 4). Stillother tips 14 in the inventory have treatment ends that are tapered to a fine point (e.g., treatment end 22 10), to a round, blunt distal surface 24 (e.g., treatment end 22 6) or to a flat surface (e.g., end 22 5). The treatment ends of some tips form a straight line fromhousing 28 to surface 24 (e.g., end 22), while others include a bend of 30°, 45°, or 90° (e.g., ends 22 7, 22 6, 22 9, respectively). Another type oftip 14 includes atreatment end 22 13 with two bends, appropriate for performing a capsulotomy. - In operation, a user selects a
tip 14 from the inventory and inserts the selectedtip 14 intohandle 12 simply by aligningprotrusion 38 onhousing 28 withslot 58 inhandle 12 and inserting connection end 25 oftip 14 intohandle opening 56. The proximal end ofhousing 12 entershandle opening 56, andprotrusion 38 slides intoslot 58. Asbutton 42 ofprotrusion 38 entersround opening 60, end 59 ofslot 58 expands. Aftertip 14 is fully inserted, end 59 ofslot 58 snaps back to its original size to holdbutton 42 firmly inopening 60. The exterior surfaces ofhousing sections inner surfaces opening 56.Tip 14 is thus held inhandle 12 by a friction fit as well as by a snap fit. - As
tip 14 is being inserted,outer electrode 18 andinsulator 20enter contact 76, andouter electrode 18 firmlycontacts conductor 75. Similarly,inner electrode 16 slides intocontact 74 andreceptacle 78, andproximal end 17 ofelectrode 16 engagesconductor 77. Friction between the adjacent surfaces ofelectrodes conductors tip 14 disengaging fromhandle 12. - Referring to FIG. 7, the user connects
device 10 to a highfrequency power source 150 by connecting astandard socket 152 on acable 153 to connector pins 88, 90.Power source 150 provides electrical power tocontacts pins electrodes 16, 18 (FIG. 1). Holdingbody 50 ofhandle 12 andhousing 28 oftip 14, the user places surface 24 ofelectrodes tissue 154 to be treated, e.g., within the eye. The voltage applied byelectrodes - After use, the user detaches
tip 14 fromhandle 12 by pullingtip 14 axially out ofopening 56.Protrusion 38 ontip 14 forces edges 59 ofslot 58 outward asbutton 42 is pulled throughslot 58. The user discardstip 14, and sterilizes handle 12 (e.g., by autoclaving) for subsequent use. - The user then selects a new tip from the inventory of tips. For example, the user may choose
tip 14 withtreatment end 22 1, shown in FIG. 7. The user then inserts the new tip inhandle 12, as described above, and performs a new surgical procedure. - Alternatively, the user may sterilize and reuse
tip 14 instead of discardingtip 14 after a single use. In this case,tip 14 would be made from reusable material capable of, e.g., withstanding autoclaving. -
Proximal section 55 anddistal section 54 ofhandle 12 may also be combined into a unitary, molded body. The handle and tip may have other shapes: For example, referring to FIG. 8,surgical device 100 has anon-cylindrical handle 112 that axially tapers between relativelylarge diameter regions smaller waist regions narrow waist region 112 d can be gripped between the user's fingers to assist in preciselytreatment end 122 oftip 114 in the body. - The
housing 128 oftip 114 is hourglass-shaped, tapering from a relatively wideproximal region 129 to a narrowintermediate waist 130, and then to a somewhat larger-diameterdistal region 131. With this shape,housing 128 fits securely in the user's hand (withwaist 130 being gripped between the user's fingers) when insertingtip 114 into and removingtip 114 fromhandle 112. Both handle 112arid tip housing 128 may be ribbed 133 to further enhance gripping. - Referring to FIGS.9-27, tip 14 (or tip 114) may be delivered in a reinforced, sterile “blister”
package 200 which allows for easy insertion of the tip ontohandle 12 arid removal of the tip from the handle, without any direct contact between the user's hand and the tip.Package 200 can be sterilized and sealed within a sterile pouch (not shown) for use during surgery. Package 200 containingtip 14 may also be sterilized after insertion in the sterile pouch preferably using ethylene oxide (ETO) or gamma rays. -
Package 200 is made from a single piece of thin, flexible plastic material, preferably 0.015 inch thick Kodak “Kodar” 6763 clear co-polyester medical PETG. Another material that may be used forpackage 200 is polyvinyl chloride.Package 200 is preferably made by vacuum molding the plastic material. Other methods ofmaking package 200 include injection molding and pressure or vacuum thermoforming of the plastic material. - Referring to FIGS.9-11,
package 200 includes atop portion 205 and abottom portion 206 connected by arigid hinging segment 207. Hingingsegment 207 includes two hingingpoints 207 a which create ablunt shelf 207 b, and twowalls 207 c which provide rigidity for the hinging segment.Package 200 is folded into a closed position by foldingtop portion 205 andbottom portion 206 toward each other along hingingsegment 207, and forming the hinging segment itself by folding along hingingpoints 207 a. FIGS. 9 and 10show package 200 prior to folding, and FIGS. 11-14 show the package with the top and bottom portions folded together. - Referring to FIGS.11-14, when
package 200 is folded together, moldedtop portion 205 and moldedbottom portion 206 form acavity 220 shaped to receive theentire tip 14.Top portion 205 andbottom portion 206 both includeflat surfaces package 200 is folded together.Cavity 220 may be shaped to accept, discharge and protect all types of shapes of tips that are used with handle 12 (e.g., the tips shown in FIGS. 6A-6E).Cavity 220 includes anupper chamber 224 and alower chamber 226.Cavity 220 is also shaped to receive the conically shapedhousing 28 oftip 14, including sloping,grooved exterior surface 30.Cavity 220 has anopening 222 intolower chamber 226 that is large enough only to receive the end ofhandle 12 for insertingtip 14 onto and removing the tip from the handle. The electrical contacts of the tip electrodes which extend fromtip 14 and attach to handle 12 are recessed withinopening 222 to avoid accidental contact with the user's hands. -
Upper chamber 224 is formed by moldedsections top portion 205 andbottom portion 206, respectively, when the top and bottom portions are folded toward each other.Upper chamber 224 is large enough to accommodate the electrodes of both straight and bent tips, such as the tips shown in FIGS. 6A-6E. -
Housing 28 oftip 14 is securely held and properly oriented inpackage 200 withinlower chamber 226.Lower chamber 226 includespositioning cavity 201 and a releasable locking mechanism, which includes lockingrecesses Positioning cavity 201 is shaped to receivetab 40 andbutton 42 ofprotrusion 30 ontip 14.Positioning cavity 201 preventstip 14 from rotating aboutcentral axis 260 withincavity 220.Positioning cavity 201 also prevents damage to the electrodes oftip 14 by restraining the tip from being pushed too far forward intoupper chamber 224. -
Tip 14 is rearwardly retained withincavity 220 by lockingrecesses tip 14 alongcentral axis 260 to hold the tip in place and prevent the tip from sliding out ofopening 222. Locking recesses 202, 202 a can be separated slightly radially outward fromcentral axis 260 by pushing againstramps tip 14 fromcavity 220. -
Top portion 205 includes moldedpockets 210, andbottom portion 206 includes corresponding molded interlockingbosses 211.Pockets 210 andbosses 211 are positioned so that whentop portion 205 andbottom portion 206 are folded toward each other, the bosses engage the pockets.Bosses 211 are shaped so that they fit snugly into and are frictionally held within correspondingpockets 210 when the bosses are firmly pushed into the pockets. The combination ofpockets 210 andbosses 211, as well asrigid hinging segment 207, helps to maintainpackage 200 in a closed position during shipping and usage, but allows the package to be opened manually if necessary. -
Top portion 205 andbottom portion 206 also contain interlocking horseshoe-shapedribs Ribs cavity 220 and the package exterior to help to avoid accidental release of the tip retained in the package and to prevent the sharp end of the tip electrode from sliding out through the sides ofpackage 200. As withpockets 210 andbosses 211,ribs top portion 205 andbottom portion 206 are folded together the ribs engage each other, and the ribs are shaped so that one of the ribs fits snugly into and is frictionally held within corresponding the rib. Hingingsegment 207 andribs package 200 during insertion oftip 14 onto and removal of the tip fromhandle 12, which helps to avoid contact between the tip and the user's hand. -
Double arrows 242 molded intotop portion 205 indicate the location for proper placement of the user's fingers to grasppackage 200 during insertion oftip 14 onto and removal of the tip fromhandle 12. Singledirectional arrow 244 molded onto thetop portion 205 ofpackage 200 indicates the direction of handle movement and ensures correct alignment betweenhandle 12 andtip 14 during insertion and removal.Top portion 205 may also contain alabeling area 246, in which a message or text is molded into the plastic, preferably by hot stamping. - Referring to FIGS.11-13,
package 200 is used to inserttip 14 onto and to remove the tip fromhandle 12 without direct contact between the tip and the user's hand. To inserttip 14 ontohandle 12, the user firmly graspspackage 200 betweendouble arrows 242 and pushes the end of the handle intoopening 222 along the direction of singledirectional arrow 244. When the end ofhandle 12 is pushed intopackage 200 throughopening 222,bevel 57 ofhandle 12urges locking recesses tip housing 28 by pushing againstramps tip 14 fromlower chamber 226.Handle 12 is pushed intocavity 220 untiltip 14 is fully inserted onto the handle. The interface betweentip 14 and handle 12 prevents lockingrecesses tip housing 28 during withdrawal of the handle frompackage 200 with the fully inserted tip. - To remove inserted
tip 14 frompackage 200, the user releases the tension placed on the package betweendouble arrows 242 and withdraws handle 12 in the direction opposite to singledirectional arrow 244. The retention oftip 14 onhandle 12 is sufficient to keeptip 14 fully inserted onhandle 12 during withdrawal frompackage 200 and during use in a surgical procedure, but allows for ease of removal oftip 14 fromhandle 12 with or without the use ofpackage 200. -
Package 200 may also be used to remove an insertedtip 14 fromhandle 12. The user pushes handle 12 with insertedtip 14 intoopening 222 in the direction ofarrow 244, making sure thatprotrusion 30 oftip 14 is aligned to slide intopositioning cavity 201. As the user pushes handle 12 throughopening 222 andtip 14 enterscavity 220,bevel 57 ofhandle 12contacts ramps recesses central axis 260, allowingtip 14 to fully entercavity 220. The user then graspspackage 200 betweendouble arrows 242 with his or her fingers to apply pressure to holdtip 14 withincavity 220.Tip 14 is then separated from handle 12-by pulling the handle away from the tip. As the user withdraws handle 12 from opening 222, the interface betweentip 14 and handle 12 separates, and handle 12 moves downramps central axis 260 and recapturetip 14.Tip 14, securely held within itspackage 200, may then be discarded or stored for subsequent use during the same surgical procedure. - The use of
package 200 for each tip provides the user with efficient access to a variety of different tips during surgery. Since a tip may be used several times for the same patient during a single surgical procedure, the tips used with the patient may be efficiently stored in their packages during the surgical procedure, without contamination due to handling by the user. The return of the tips to their packages during a surgical procedure allows for minimal disposal and waste of tips. Further, by placing each tip into its package after it is used during a surgical procedure, a variety of tips used with a single handle during the surgical procedure may be efficiently organized. - Moreover,
package 200 allows the user to remove used tips from the handle in a simple fashion and without direct contact between the tips and the user's hand. Thus, patient-contaminated tips may be safely manipulated and stored during surgery and disposed of after surgery. In particular, use of the package to insert tips onto and remove tips from the handle decreases the risk of puncturing hazardous waste bags and infecting the user or clinical staff. - Other embodiments are within the following claims. For example, the package can also be used with monopolar, diathermized and non-bipolar tips, as well as other sharp tips such as cannulae, pics and blades, that are removably attachable to a handle.
- What is claimed is:
