Description
Technical field
The present invention relates to a kind of Orthopeadic Surgery medical instruments field, the universal rongeur of especially a kind of orthopaedics.
Background technique
It is well known that stinging the medical instrument for cutting or correcting bone when rongeur is a kind of bone surgery.Rongeur is by clamping
The joint of handle, plier and its changeover portion forms, in use, making left plier and right plier realize opening or closure by operating clamp handle
State is cut or is corrected so that left and right plier is bitten tissue and sting.When concrete application, plier part is not able to rotate, institute
It is restricted with its application range and using function, when stinging the mode of operation for cutting different parts or the different lower bending angles of needs,
Patient needs to frequently replace friction clamp mouth rongeur and curved forceps mouth rongeur, this has been resulted in, and surgical procedure speed is slow, and time-consuming, makes
Bleeding, infection probability increase, also increase operation risk, and affect the quality of operation to a certain extent.
Summary of the invention
The purpose of the invention patent is to provide for a kind of universal rongeur of orthopaedics, solves operation tool replacement frequently, speed
The problem of degree is slow, and time-consuming, increases the probability of bleeding, infection.
The purpose of the invention patent is achieved in that universal rongeur includes: plier, gimbal suspension and clamp handle；Plier
The both ends of gimbal suspension are connected to clamp handle；Clamp handle drives plier opening and closing, clamp handle and plier to bend by hinge joint of gimbal suspension.

Part.
Beneficial effect, due to the application of the above technical scheme, when patient is when using rongeur, with finger turn locking screw
Silk is in lock screw and screws or relaxed state.When lock screw is in tightening state, the gimbal suspension block of upper end two with
It can not be longitudinally rotated along its axis between the gimbal suspension block of lower end two, bending angle is in stationary state under plier, and patient is at this time
The plier of existing lower bending angle can be used to sting and cut or correct bone and other people body tissues.When lock screw is in relaxed state
When, the gimbal suspension block of upper end two can be longitudinally rotated with the gimbal suspension block of lower end two along its axis, and patient appropriately rotates plier
Lower bending angle, so that bending angle is in proper states, the plier after adjusting lower bending angle can be used to sting at this time for patient
Cut or correct bone or other tissues.
It is compared with the prior art, instrument nurse searching is omitted in this universal rongeur, and transmitting and patient replace different pincers
The process adapted between the rongeur of bending angle under mouth avoids frequently replacing tool in operation, can effectively reduce operation
Time, the quality of operation is improved, and further decrease operation risk, has achieved the purpose that the invention patent.
Advantage: the present invention realizes the unification of the curved forceps mouth rongeur of friction clamp mouth rongeur and various lower bending angles, when stinging
When cutting different parts or needing the mode of operation of different lower bending angles, avoids patient and frequently replace friction clamp mouth rongeur and curved forceps
The complicated processes of mouth rongeur make patient settle the step of instrument is replaced in realization at one go in art, can effectively reduce the operating time,
Reduce operation risk.
