Abstract
A clip applicating device (10) deploys surgical clips (24) to ligate ducts and/or vessels during surgical procedures. While the clip (24) is deployed the device (10) simultaneously delivers electrosurgical energy to the affected tissue through the clip (24).
This causes the clip (24) and the adjacent tissue to be fused together, resulting in more secure surgical clips. The clipping device (10) may be configured either as a bipolar or a monopolar instrument. The clip applicating device (10) has a handle portion (12) with a trigger mechanism (14), and an electrical connector port (18). The connector port (18) is able to be connected to insulated wire (20) which communicates electrosurgical energy from generator (26). The generator (26) is also connected to ground element (34) through conductive wire (36). The energy is delivered to the jaws (22a, 22b) through barrel (16) by activating switch (30).

The clip applicator 10 includes a handle portion 12 having a trigger mechanism ~4. l~djacent the handle is an elongate member 16 which houses a '' supply ~f surgical clips (not shown as well as an X30 actuatihg mechanism, described below, which assists in deploying the clips. The handle 12 also includes an electrical connector port 18 which is able to be connected to insulated wire ~0 which communicates electrosurgical energy from generator 26.
35 ' ..., CVO 93/~8741 ~ ~ '~ ~ ~ b PCT/~1~92/~8800 _5_ An actuating mechanism adaptable for use with the present invention is illustrated in Figure 2. The actuating mechanism preferably includes an actuating rod 21 which communicates with the trigger mechanism 14 through a catch 19 which mounts within groove 17 of trigger 14. Actuating rod 21 also communicates with paired clamping jaws 22a, 22b which extend from a distal end of barrel 16. The clamping jaws 22a, 22b are adapted to engage and deploy a surgical clip 24. Surgical clips can be deployed by activation of the trigger mechanism 14, causing actuating rod 21 to move backwards (toward the handle 12) while closing clamping jaws 22a, 22b together.
When the clamping jaws 22a, 22b are closed, the surgical clip 24 disposed between the jaws is clamped about a duct or vessel. ~nce a clip is deployed, a new clip may be positioned between clamping jaws 22a, 22b either automatically or manually.
Electrosurgical generator 26 communicates with clipping device 10 through eternal conductive ' wire 20 which connects to the clipping device through gort 18. As shown in Figure 2, port 18 communicates with internal conductor wire 25 which extends into the clipping device 10. Preferably, internal wire 25 is attached ~o a conductive portion of the actuating mechanism v~rhich is in electrical Communication with :t;

_6_ material and which is in electrical communication with clamping jaws 22a, 22b. The portions of the clipping device 10 which are in electrical communication with wire 20 (e.g., actuating rod 21 andlor clamping jaws 22x, 22b) preferably are electrically isolated from the remainder of the tool.
Upon activating the delivery of current to tool Z0, for example by activating switch 30, current will be delivered through internal wire 25 and communicated to surgical clip 24 through actuating rod 21 and/or clamping jaws 22a. 22b.
Figure 1 further illustrates the configuration of the clip applicating device 10 when ,r.A
used as a monopolar instrument. This embodiment utilizes a ground element 34 which is remote from the device 10, and placed in contact with a patient's a body. The ground element 34 serves as a return electrode and communicates with generator 26 through .;.5 conductive wire 36. In such a configuration the clip x~ 24 serves as the active electrode which delivers electrosurgical energy to tissue which it contacts.

Wire 52 serves as a ground wire which communicates between jaws 40a, 40b (or the actuating mechanism r=3 associated with jaws 40a, 40b). Upon activation of a trigger mechanism jaws 40a, 40b and 42a, 42b close together to deploy clips 44 and 46. At the same time a control switch is activated to deliver electrical .,vY
current to the actuating mechanism associated with jaws 42a, 42b andsor directly to jaws 4Ba, 42b, and hence to clip 46. When the clip contacts tissue.
current is conveyed to the tissue causing the tissue and clip to be fused together. The electrosurgical energy also promotes tissue-to-tissue fusion. The applied current is returned to generator 26.through clamping jaws 40a, 4Ob. the actuating mechanism associated with these jaws, and wire 52.
Generator 26 supplies electrosurgical energy to the clipping device 10 in the manner described above. virtually any generator able to provide electrosurgical energy for medical applications may be used with the present invention. Preferably, the generator is a voltage determinative. law source impedance generator which provides radio frequency energy. preferably, a suitable generator can supply up to 2 amps of current and has an impedance value of less than 10 ohms.
The enexgy supplied by the generator to the clipping device is preferably in the radio frequency (RFC range. Although virtually any frequency in the ~Y(D 93/0741 PCf/US92/0~~.
ItF range may be supplied to the clipping device, the preferred range is about 500 to 700 KHz, and most preferably about 550 ~Iz.
The energy requirements of the clipping, ,.
device are dynamic and will vary depending upon the impedance values of tissue into which'the clips are inserted. The impedance of tissue varies among tissue types and the amount of blood present in or around the tissue. The amount of current delivered by the tool to the tissue depends on the impedaince of the tissue. ~nlhere the tissue contacted has a lower impedance value, more current will be delivered to the tissue through the clip, and, ~coraversely, less current will be delivered where the tissue has a higher impedance value. Generally, the amount of current delivered ranges between 0.5 and 2.0 amps.
The voltage applied to the tissue between the clip serving as the active electrode and the return electrode or ground plate is between about 50 and 100 volts S.
Figures ~lA, ~B and 4C illustrate the manner in which surgical clips are deployed in accordance with the present invention. A vessel 32 to be ligated is disposed between clamping jaws 22a, 22b and surgical clip 2~. Ltpon activating the triggering mechanism, the clamping jaws move together as shown in Figure 4~, causing surgical clip 24 to close upon vessel 32. ~rThen the triggering action is completed the clip 2~ remains adhered to the vessel 32 as illustrated in Figure 4C. While the clip is applied over the vessel, electrosurgical energy is delivered .,~1~~ 9310~74~ ~ ~ c~ ~~ ~ ~ PCT/US92108~00 -~ - ~ t~ _'~
through the clip 24, acting as an active electrode.
Current is maintained for a suitable period of time, usually 5 to 15 seconds, to enable tissue-to-clip and tissue-to-tissue fusion to occur. As illustrated in Figure l, a ground clamp 34 which communicates wa.t~h the generator through wire 36, can serve as the return electrode when the surgical clip applicator functions as a monopolar surgical device.
The actuating mechanism of clip applicator 10 preferably is made of a conductive material which has a relatively high tensile strength. Egemplaxy ;,{
materials include surgical grade stainless steel and aluminum. Clamping jaws 22a, 22b likewise are made r:; 15 of a surgically compatible, conductive material suitable to enable current to be communicated through the clamping jaws 22a, 22b to clip 24. The surgical v clips 24 used with the clipping device of the ;g K
invention may be with a variety of constructions and may be made of variety of conductive, surgically compatible materials which are w~11 known in the art. his illustrated the surgical clip may be substantially U- or V-shaped. but various other shapes or constructions are possible as well.
a The hand~.e portion 12, trigger 14, and the barrel 16 are electrically isolated from the remainder of the device. Preferably, these components are made of, or are coated with, non-conductive materials such as suitable polymers.

Wire 52 serves as a ground wire which communicates between jaws 40a, 40b (or the actuating mechanism r=3 associated with jaws 40a, 40b). Upon activation of a trigger mechanism jaws 40a, 40b and 42a, 42b close together to deploy clips 44 and 46. At the same time a control switch is activated to deliver electrical .,vY
current to the actuating mechanism associated with jaws 42a, 42b andsor directly to jaws 4Ba, 42b, and hence to clip 46. When the clip contacts tissue.
current is conveyed to the tissue causing the tissue and clip to be fused together. The electrosurgical energy also promotes tissue-to-tissue fusion. The applied current is returned to generator 26.through clamping jaws 40a, 4Ob. the actuating mechanism associated with these jaws, and wire 52.
Generator 26 supplies electrosurgical energy to the clipping device 10 in the manner described above. virtually any generator able to provide electrosurgical energy for medical applications may be used with the present invention. Preferably, the generator is a voltage determinative. law source impedance generator which provides radio frequency energy. preferably, a suitable generator can supply up to 2 amps of current and has an impedance value of less than 10 ohms.
The enexgy supplied by the generator to the clipping device is preferably in the radio frequency (RFC range. Although virtually any frequency in the ~Y(D 93/0741 PCf/US92/0~~.
ItF range may be supplied to the clipping device, the preferred range is about 500 to 700 KHz, and most preferably about 550 ~Iz.
The energy requirements of the clipping, ,.
device are dynamic and will vary depending upon the impedance values of tissue into which'the clips are inserted. The impedance of tissue varies among tissue types and the amount of blood present in or around the tissue. The amount of current delivered by the tool to the tissue depends on the impedaince of the tissue. ~nlhere the tissue contacted has a lower impedance value, more current will be delivered to the tissue through the clip, and, ~coraversely, less current will be delivered where the tissue has a higher impedance value. Generally, the amount of current delivered ranges between 0.5 and 2.0 amps.
The voltage applied to the tissue between the clip serving as the active electrode and the return electrode or ground plate is between about 50 and 100 volts S.
Figures ~lA, ~B and 4C illustrate the manner in which surgical clips are deployed in accordance with the present invention. A vessel 32 to be ligated is disposed between clamping jaws 22a, 22b and surgical clip 2~. Ltpon activating the triggering mechanism, the clamping jaws move together as shown in Figure 4~, causing surgical clip 24 to close upon vessel 32. ~rThen the triggering action is completed the clip 2~ remains adhered to the vessel 32 as illustrated in Figure 4C. While the clip is applied over the vessel, electrosurgical energy is delivered .,~1~~ 9310~74~ ~ ~ c~ ~~ ~ ~ PCT/US92108~00 -~ - ~ t~ _'~
through the clip 24, acting as an active electrode.
Current is maintained for a suitable period of time, usually 5 to 15 seconds, to enable tissue-to-clip and tissue-to-tissue fusion to occur. As illustrated in Figure l, a ground clamp 34 which communicates wa.t~h the generator through wire 36, can serve as the return electrode when the surgical clip applicator functions as a monopolar surgical device.
The actuating mechanism of clip applicator 10 preferably is made of a conductive material which has a relatively high tensile strength. Egemplaxy ;,{
materials include surgical grade stainless steel and aluminum. Clamping jaws 22a, 22b likewise are made r:; 15 of a surgically compatible, conductive material suitable to enable current to be communicated through the clamping jaws 22a, 22b to clip 24.
