The technical proposal is as follows: the utility model provides a tendon sheath of preventing accidental injury tendon opens device, including the sheath, the connecting piece, the handle, the cutter body, blade and push rod, sheath rear portion upside is connected with the connecting piece, connecting piece upper portion rear side is connected with the handle, it has the guide way to open on the sheath, sliding type is connected with the cutter body in the guide way, cutter body front portion upside is connected with the blade, the blade is the oblique structure, can produce the shearing force with the tendon sheath tissue through sliding, realize the incision of tendon sheath tissue, cutter body rear portion upside is connected with the push rod, the sheath can carry out effectual protection to the tendon, thereby effectually avoid the blade to harm the tendon tissue, the push rod can drive the blade through the cutter body and slide on the guide way, thereby can open the tendon sheath.

As a further preferable scheme, the push rod also comprises a push disc, the top of the push rod is connected with the push disc, and the push disc is convenient for people to push the push rod.

As a further preferable scheme, the handle is provided with a holding soft cushion, and the holding soft cushion can improve the comfort level of the holding personnel.

As a further preferable scheme, the pushing disc is provided with an anti-slip groove, and the anti-slip groove can increase friction force between the pushing disc and the hand of a gripping person, so that the problem of slipping during use is prevented.

As a further preferable scheme, the handle is of a columnar structure, can be matched with the hand of a grasping person, and improves grasping comfort.

As a further preferable scheme, the front end of the sheath is arc-shaped, so that the sheath can penetrate through gaps between the tendon sheath and the tendon.

The utility model has the following advantages: 1. according to the utility model, the sheath with the arc structure is used for protecting tendon tissues of a patient, and the blade is used for cutting the tendon sheath, so that the effects of preventing the blade from damaging the tendon tissues, effectively protecting the tendon and improving the safety are achieved.

2. According to the utility model, through designing the radian of the sheath with different sizes, the effect of adapting to tendon tissues with different thicknesses is achieved.
