The present invention relates to a pouch type traction device which easily receives a non-operation region and pulls the non-operation region since the inlet of the traction device for pulling a non-operation region spaced from an operation region is maintained in an open state in a body cavity. For this, the pouch type traction device is inserted into a body cavity and pulls a non-operation region spaced from an operation region. The pouch type traction device includes an accommodation pouch for accommodating a non-operation region and a maintaining unit which maintains the inlet of the accommodation pouch in an open state in a body cavity. |
