Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a nasal septum bone rongeur. Background Art
[0002] Nasal septum deviation is a structural deformity caused by certain factors during the development of the nasal septum. It is deviated to one or both sides or locally protruded in shape, which can affect the physiological function of the nasal cavity and cause a series of pathological changes. Usually, a corrective surgery for the nasal septum is required. Among them, the surgical incision for correcting the nasal septum is mostly in the anteroinferior part of the nasal septum. Through the incision, the bilateral nasal septal mucoperichondrium is separated, and then the deviated nasal septal cartilage or bone is removed. Then, the traditional bone rongeur is used to bite off the nasal septal cartilage or bone that needs to be removed above, below or behind.
[0003] However, the head of the traditional nasal septum bone rongeur is small, and the amount removed each time is small, while the bone or cartilage that needs to be removed is mostly large pieces, which is likely to cause a long operation time, fatigue of the doctor's hand, and affect the surgical precision.
[0004] Therefore, the utility model provides a nasal septum bone rongeur to solve the above problems. Content of the Utility Model

The top of the right handle is hinged to the top of the left handle through a first connecting piece. A first rotating block is fixedly connected to the top of the right handle, and a second rotating block is fixedly connected to the top of the left handle. A first jaw is hinged to the front end of the first rotating block through a second connecting piece, a second jaw is hinged to the front end of the second rotating block through a third connecting piece, and the middle position between the first jaw and the second jaw is hinged through a fourth connecting piece.
[0007] Preferably, spring sheet slots are provided on the sides of the right handle and the left handle close to each other, and spring sheets are installed on the sides of the right handle and the left handle close to each other through screws. The bottom end of each group of spring sheets is inserted and connected to the corresponding spring sheet slot.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1:
[0023] Please refer to Figures 1-4 , the nasal septum rongeur, which includes a right handle 1 and a left handle 2. The top ends of the right handle 1 and the left handle 2 are hinged through a first connecting member. A first rotating block 4 is fixedly connected to the top end of the right handle 1, and a second rotating block 5 is fixedly connected to the top end of the left handle 2. A first jaw 6 is hinged to the front end of the first rotating block 4 through a second connecting member, and a second jaw 7 is hinged to the front end of the second rotating block 5 through a third connecting member. The middle positions of the first jaw 6 and the second jaw 7 are hinged through a fourth connecting member.
[0024] The first connecting member is a screw 3, the second connecting member and the third connecting member are both fixed pins 8, and the fourth connecting member is a jaw screw 9.
[0025] A hand guard block 11 is fixedly installed on the outer wall of the right handle 1.
[0026] A fitting groove 17 corresponding to the second jaw 7 is formed on the first jaw 6, and a cutting groove is formed at the corresponding position of the second jaw 7 with respect to the fitting groove 17.
[0027] When using this device, the user holds the provided right handle 1 and left handle 2, and then applies a certain force, so that the first jaw 6 and the second jaw 7 are driven by the provided first rotating block 4 and second rotating block 5 to perform shearing on the surgical site. Among them, through the settings of the fitting groove 17 and the cutting edge, the surgical resection efficiency is improved to a certain extent, and the surgical time is effectively reduced, thereby reducing the burden on the doctor during the operation. In addition, through the setting of the hand guard block 11, it is convenient for the user to exert force with the hand.
[0028] Embodiment 2:
