The cartilage arc graver comprises a knife handle 1, a connecting piece 2 and a graver 3 according to the attached drawings 1-2 of the specification.

The connecting piece 2 is detachably arranged at one end of the knife handle 1. Specifically, as shown in fig. 1, the coupling member 2 is detachably mounted at the left end of the shank 1.

The graver 3 is substantially V-shaped, and the graver 3 is mounted on the connecting member 2.

The inventor finds out in the working process that: in the traditional augmentation rhinoplasty, carve an arc-shaped groove on one face of the cartilage membrane, but this method carves the time overlength, the troublesome poeration, and the installation is unstable, therefore the inventor installs the cartilage membrane and divides into two, carry out through the carving knife and cut an arc-shaped groove 81 (as shown in fig. 3) that runs through cartilage membrane 8 at cartilage membrane 8, fix two cartilage membranes 8 together again, then fix on the people's nose through arc-shaped groove 81, therefore, can fix cartilage membrane 8 more stably, the nose is more three-dimensional, but among the prior art, do not have this kind of carving scalpel, need medical personnel to carve through the scalpel, operation carving time is long like this, and the recess size on two cartilage membranes 8 is inconsistent, influence doctor's subsequent operation.

According to the cartilage arc-shaped graver according to the embodiment of the present invention, the graver 3 is installed on the connecting member 2 by the substantially V-shaped graver 3. Therefore, when the rib cartilage membrane is carved by an operator, the rib cartilage membrane can be carved by the straight carving knife 3, so that the operation time is reduced, the sizes of the grooves on the two cartilage membranes are consistent and neat, and the subsequent nose augmentation operation of a doctor is facilitated.

Further, the included angle between the first blade 31 and the second blade 32 is between 120 ° and 150 °. Therefore, the angle of the groove of the cartilage diaphragm is 120-150 degrees, and the subsequent installation and fixation of the cartilage diaphragm are facilitated.

Further, the graver 3 includes a first blade 31, a second blade 32, and an arc-shaped transition blade 33, and the arc-shaped transition blade 33 is connected to the first blade 31 and the second blade 32, respectively. Specifically, as shown in fig. 2, the graver 3 comprises a first blade 31, a second blade 32 and an arc-shaped transition blade 33, and the right side of the first blade 31 is connected with the arc-shaped transition blade 33 and the left side of the second blade 32 is connected with the arc-shaped transition blade 33, thereby making the arrangement of the graver 3 more reasonable.

Further, the other end of the knife handle 1 is provided with an anti-slip pad 4. Specifically, as shown in fig. 1, the left end of the knife handle 11 is provided with a non-slip pad 45, so that the doctor is prevented from slipping during operation, and the use by the doctor is facilitated.

Further, one end of the tool shank 1 is provided with a mounting groove 5 extending along the radial direction, the connecting piece 2 extends into the mounting groove 5, and the tool shank 1 and the connecting piece 2 are mounted together through a fixing piece 7. Thereby fixing the connection to the shank 1.

Further, cartilage arc carving tool still includes pivot 6, and pivot 6 wears to establish between connecting piece 2 and handle of a knife 1, and mounting 7 is in the same place connecting piece 2 through mounting 7 through pivot 6 to the angle between adjustment connecting piece 2 and the handle of a knife 1. Specifically, as shown in fig. 1, the right-hand member of handle of a knife 1 is equipped with mounting groove 5 that does not have the side, connecting piece 2 wears to establish in mounting groove 5 through pivot 6, the both ends of pivot 6 stretch out handle of a knife 1 and outside and be equipped with the screw thread, mounting 7 is the nut, from this through mounting 7 and the cooperation of pivot 6, make connecting piece 2 fix together through mounting 7, when the angle between first tool bit of needs adjustment and second tool bit and handle of a knife 1, unscrew mounting 7 and adjust the angle between connecting piece 2 and the handle of a knife 1 through pivot 6, make things convenient for doctor's use from this.

Further, the graver 3 is detachably mounted on the connecting member 2 by means of a fastener. Specifically, as shown in fig. 1, the graver 3 is mounted on the connecting member 2 by means of screws or bolts, thereby facilitating replacement of the graver 3.
