Detailed Description

In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.

The utility model discloses a this novel oval formula handle oral cavity mouth gag device, including opening hook 1 and ware body frame and constitute wherein, ware body frame including left pincers handle 2 and right pincers handle 3, opening hook 1 and ware body frame install the upper end at the ware body frame, the middle part of left pincers handle 2 and right pincers handle 3 articulated each other, the lower extreme of left pincers handle 2 and right pincers handle 3 have the finger circle respectively, as shown in fig. 2a and 2b, the finger circle of left pincers handle 2 be circular, as shown in fig. 3a and 3b, the finger circle of right pincers handle 3 be oval.

As the preferred embodiment of the utility model, the ware body frame still include lock tooth 5, lock tooth 5 fix on left pincers handle 2 through the round pin axle to pass the lock tooth's socket of right pincers handle 3.

As the preferred embodiment of the present invention, the body frame further includes a branchial shaft screw 4, the left forceps handle 2 and the right forceps handle 3 are connected by the branchial shaft screw 4, and the left forceps handle 2 and the right forceps handle 3 support to rotate around the branchial shaft screw 4.

As the preferred embodiment of the utility model, the hook 1 that opens include that the hook is opened on a left side and the hook is opened on the right side, the hook is opened on a left side and the hook is opened on the right side through welded connection respectively on left pincers handle 2 and right pincers handle 3.

As a preferred embodiment of the present invention, the heads of the left and right opening hooks are bent forward.

The utility model discloses an among the concrete implementation mode, an oval handle formula mouth gag that department of stomatology used, convenient operation is disclosed, during mainly used oral surgery, the expansion oral cavity, expose tooth and oral cavity tissue, increase the operation field of vision.

The utility model relates to a convenient oval handle formula mouth gag of operation. As shown in figure 1, the device consists of an opening hook 1 and a device body frame, wherein the device body frame comprises a left clamp handle 2 of a circular finger ring, a right clamp handle 3 of an oval finger ring, a gill shaft screw 4 and locking teeth 5.
