A modular surgical clip pack, comprising: a first modular clip cartridge and a second modular clip cartridge, each modular clip cartridge including: a body portion including: a first wall having an outer surface defining a first mating feature (70, 70'); and a second wall having an outer surface defining a second mating feature; and at least one clip compartment (40, 42, 44) defined in the body portion configured to releasably retain at least one surgical clip therein; wherein one of the first mating feature and the second mating feature of the first modular clip cartridge is configured to selectively engage the other of the first mating feature and the second mating feature of the second modular clip cartridge to selectively connect the first and second modular clip cartridges into a unitary arrangement to define the modular surgical clip pack, wherein the outer surface of the first wall further defines a first protuberance and a second protuberance symmetrically opposed to the first protuberance, wherein the first mating feature (70, 70') is disposed between the first and second protuberances; and the outer surface of the second wall further defines a first recess and a second recess symmetrically opposed to the first recess, wherein the second mating feature is disposed between the first and second recesses, wherein the first and second protuberances (71, 73) of one of the first and second modular clip cartridges (10, 10') are configured to selectively engage with the first and second recesses (81, 83) of the other of the first and second modular clip cartridges to lock the first and second modular clip cartridges into the unitary arrangement. a first modular clip cartridge and a second modular clip cartridge, each modular clip cartridge including: a body portion including: a first wall having an outer surface defining a first mating feature (70, 70'); and a second wall having an outer surface defining a second mating feature; and at least one clip compartment (40, 42, 44) defined in the body portion configured to releasably retain at least one surgical clip therein; a body portion including: a first wall having an outer surface defining a first mating feature (70, 70'); and a second wall having an outer surface defining a second mating feature; and a first wall having an outer surface defining a first mating feature (70, 70'); and a second wall having an outer surface defining a second mating feature; and at least one clip compartment (40, 42, 44) defined in the body portion configured to releasably retain at least one surgical clip therein; wherein one of the first mating feature and the second mating feature of the first modular clip cartridge is configured to selectively engage the other of the first mating feature and the second mating feature of the second modular clip cartridge to selectively connect the first and second modular clip cartridges into a unitary arrangement to define the modular surgical clip pack, wherein the outer surface of the first wall further defines a first protuberance and a second protuberance symmetrically opposed to the first protuberance, wherein the first mating feature (70, 70') is disposed between the first and second protuberances; and the outer surface of the second wall further defines a first recess and a second recess symmetrically opposed to the first recess, wherein the second mating feature is disposed between the first and second recesses, wherein the first and second protuberances (71, 73) of one of the first and second modular clip cartridges (10, 10') are configured to selectively engage with the first and second recesses (81, 83) of the other of the first and second modular clip cartridges to lock the first and second modular clip cartridges into the unitary arrangement.
