The invention provides a string bin of purse-string forceps. The string bin of the purse-string forceps comprises a fixing jaw and a gear shaft. The string bin of the purse-string forceps further comprises a spool shaft connected with the gear shaft and a spool arranged on the spool shaft, wherein the spool is fixed above the fixing jaw, and suture string of the string bin is wound on the spool. According to the string bin of the purse-string forceps, the spool is arranged and fixed above the fixing jaw by using the free space above the fixing jaw, and therefore the boundary dimension of the fixing jaw is reduced. Compared with a background technology, the fixing jaw of the string bin is small in the boundary dimension, an operator can obtain a good surgical view field, therefore, the operation of the operator is made to be accurate, and risks in surgeries are reduced.
