The invention relates to a surgery medical instrument, in particular to a push-pull type digestive system minimally invasive surgery haemostatic forceps which is large in the occlusion force, simple in operation and free of transverse displacement. The forceps comprises a forceps head (1) and a forceps body (2), a cavity is formed by the interior of the forceps body (2), the forceps head (1) is connected with the front end of the forceps body (2) through a rotating shaft (3), end sockets arranged in the forceps body (2) are in a hinged connection with connecting rods (4) respectively, free ends of two connecting rods (4) are in the hinged connection with a transmission bar (5) together, a gear rack is arranged on one side of the transmission bar (5), the transmission bar (5) is connected with a push rod (7) through a steering gear (6), one side of the push rod (7) is provided with a gear rack, and one end of the push rod (7), which is far from the forceps head (1), extends out of the forceps body (2). By means of the connection of the connecting rods (4), the transmission bar (5), the steering gear (6) and the push rod (7), the vertical movement of the push rod (7) is converted to the chelation of the forceps head (1). The push-pull type digestive system minimally invasive surgery haemostatic forceps has the advantages that the design is reasonable, the structure is exquisite, the forceps clamping is stable, the usage is convenient, the required space of the operation is small, and the operation is flexible.
