Abstract: We construct an invariant of framed links in a handlebody by means of the spin $ j$ representation of $ {U_q}(\mathfrak{s}\mathfrak{l}(2,\mathbb{C}))$. We can see this invariant is an extension of the Jones polynomial and Kauffman's Dubrovnik polynomial. Moreover, we can obtain a linear representation of the generalized braid group associated with the Lie algebras of types $ B$ and $ C$ by applying the operators used in constructing an invariant to tangles in a solid torus.
