External cooling devices and systems for surgical instruments
A surgical system includes a portable surgical instrument and a sleeve. The portable surgical instrument includes an end effector assembly and a housing operably coupled to the end effector assembly. The housing includes a generator and a battery assembly coupled thereto and configured to supply energy to the end effector assembly for treating tissue. The sleeve is shaped complementarily to the housing and is removably positionable about the housing. The sleeve is configured to cool the housing and/or remove heat from the housing to inhibit overheating of the generator and/or the battery assembly.
1. A surgical system, comprising:
a surgical instrument including a housing having a handle configured to be grasped by a user, a shaft extending distally from the housing, and an end effector extending distally from the shaft, wherein at least one component supported on or within the housing produces heat during use of the surgical instrument; and
a cooling device configured to removably receive at least a portion of the housing of the surgical instrument when the surgical instrument is not in use, the surgical instrument configured for removal from the cooling device for use of the surgical instrument, the cooling device configured to actively cool the at least one component when the surgical instrument is received by the cooling device.
2. The surgical system according to claim 1 , wherein the cooling device is configured to actively cool the at least one component of the surgical instrument by circulating a fluid through the cooling device.
3. The surgical system according to claim 2 , wherein the cooling device defines at least one lumen extending therethrough, the at least one lumen configured to permit circulation of the fluid therethrough.
4. The surgical system according to claim 3 , further comprising a cable coupling the at least one lumen to a source of fluid.
5. The surgical system according to claim 1 , wherein the cooling device includes an active heat sink configured to actively cool the at least one component of the surgical instrument.
6. The surgical system according to claim 1 , wherein the cooling device includes a cooling plate defining a surface configured to receive the surgical instrument thereon when the surgical instrument is not in use.
7. The surgical system according to claim 1 , wherein the cooling device includes a holster defining an interior configured to receive at least a portion of the surgical instrument therein when the surgical instrument is not in use.
8. The surgical system according to claim 1 , wherein the cooling device includes a case configured to receive and enclose the surgical instrument therein when the surgical instrument is not in use.
9. The surgical system according to claim 1 , wherein the cooling device further includes at least one sensor configured to sense a temperature of at least a portion of the surgical instrument.
10. The surgical system according to claim 1 , wherein the at least one component includes a battery and a generator, the battery configured to power the generator and the generator configured to supply energy to the end effector, wherein the battery and generator produce heat during use of the surgical instrument.
11. The surgical system according to claim 1 , wherein the end effector of the surgical instrument is configured to supply RF energy to tissue to treat tissue during use of the surgical instrument.
12. The surgical system according to claim 1 , wherein the end effector of the surgical instrument is configured to supply ultrasonic energy to tissue to treat tissue during use of the surgical instrument.
13. A method of surgery, comprising:
using a surgical instrument a first time, wherein using the surgical instrument the first time includes treating tissue with an end effector extending distally from a shaft, the shaft having a housing including a handle configured to be grasped by a user, the housing extending proximally from the shaft, wherein at least one component supported on or within the housing produces heat during the use of the surgical instrument;
placing the surgical instrument such that at least a portion of the housing is removably received by a cooling device;
actively cooling the at least one component of the surgical instrument using the cooling device;
removing the at least a portion of the housing from the cooling device; and
using the surgical instrument a second time, wherein using the surgical instrument the second time includes treating tissue with the end effector.
14. The method according to claim 13 , wherein using the surgical instrument at least one of the first or second times includes treating tissue with RF energy.
15. The method according to claim 13 , wherein using the surgical instrument at least one of the first or second times includes treating tissue with ultrasonic energy.
16. The method according to claim 13 , wherein actively cooling the at least one component using the cooling device includes circulating fluid through the cooling device.
17. The method according to claim 13 , wherein actively cooling the at least one component using the cooling device includes activating an active heat sink.
18. The method according to claim 13 , further comprising sensing a temperature of at least a portion of the surgical instrument when the at least a portion of the housing is removably received by the cooling device.
