arthroscopy is a common means of clinical diagnosis and treatment of joint surgical diseases. When a fractured retracted tendon or a transplanted tendon passes through a sheath or a tunnel with a proper width in an arthroscopic surgery, maintaining the tendon stump and the tendon perimembrane completely at the tendon anastomosis is one of the key techniques for tendon repair, and it is necessary to prevent tendon adhesion and maintain normal tendon slippage. At present, most of common instruments for stretching and guiding the tendon are common clamping forceps or hemostatic forceps which are difficult to open in a narrow operation space, inconvenient to operate and easy to damage the tendon. Patent for ZL201420580095.4 is through setting up hollow sheath pole, mutual articulated fixed handle and activity handle, sets up the opening that supplies the tendon to penetrate on the terminal surface of sheath pole, and the sheath pole sets up the mounting hole that communicates with the cavity of sheath pole on being close to the outer wall of opening one end, and the articulated movable clamp splice that is equipped with spine portion in the mounting hole. During the use with the one end of hollow sheath pole stretch into to the tunnel in, then stretch into the opening to the sheath pole with the disconnected end of tendon, through rotating movable handle, with the pull of connecting rod backward, thereby pulling activity clamp splice down, the spine portion on the activity clamp splice then pierces in the tendon, then pull back the sheath pole, draw in the tendon to the other end in tunnel, spine portion through the activity clamp splice can fix the tendon, thereby can be smooth draw the tendon to the identical department of tendon, accomplish the restoration of tendon. However, the tendon can be clamped only by puncturing the tendon, and the tendon with different thickness is not easy to be transversely clamped, which is easy to cause tendon injury.

The utility model has the following contents:
