Title: JAW ASSEMBLY FOR ENDOSCOPIC BIOPSY FORCEPS
Abstract:
A jaw assembly for endoscope biopsy forceps includes a jaw frame (1), two steel wires (2) with one end of each connected to a control rod, and a left jaw (3) and a right jaw (4) that are articulated with the jaw frame (1). The other end of one steel wire (2) passes through the left jaw (3), and a ball head (5) integrated with the steel wire (2) is provided on the steel wire (2) which passes through the left jaw (3). The diameter of the ball head (5) is greater than the diameter of a hole in the left jaw (3) and the hole allows the steel wire (2) to pass through. The other end of the other steel wire (2) passes through the right jaw (4), and a ball head (5) integrated with the steel wire (2) is provided on the steel wire (2) which passes through the right jaw (4). The diameter of the ball head (5) is greater than the diameter of a hole in the right jaw (4) and the hole allows the steel wire (2) to pass through. The invention can ensure firm connections between the steel wires and the jaws as well as convenient manufacturing.
