Abstract

The utility model relates to a bone amputating knife with double angle regulating knives, particularly a knife tool for amputating (cutting) bones in the operation of bone surgery, which belongs to medical instruments. The utility model overcomes the defects of the traditional bone amputating (cutting) knife tools, such as knife entering with one knife, multiple knife entering times, low efficiency, high labor intensity for doctors, difficult operation accuracy, etc. The bone amputating knife with double angle regulating knives is provided with transverse blades and vertical blades, and the angle between the two transverse blades can be regulated, which makes the knife entering angle of the double knives predefined and enhances operation accuracy. The utility model is suitable for the bone amputating (cutting) of the reshaping operation of the bone surgery, and the bone taking of the bone grafting operation.

Description

Bone amputating knife with angle-regulatable double knives
This utility model relates to a kind of medical apparatus and instruments, especially is used for cutting the cutter of (cutting) bone in the bone surgery.
Osteotome is an indispensable operating theater instruments in the operations such as Orthopeadic Surgery is orthopedic, bone grafting, traditional osteotomy cutter, for example osteotome, osteotome, be hilted broadsword handle, hilted broadsword body, single-blade, be used in the operation bone scope of getting can only be according to osteotomy section of choosing in advance or bone grafting the time, made a cutter and changed an angle again and make second cutter, the 3rd cutter ...During bone grafting operation, need beat four blade as getting a square or rhombus bone piece; Even in orthomorphia, make the bone section be certain shape, also need in repeatedly feed for several times under the situation of angle of conversion.Because be repeatedly feed, the feed angle does not have objective criterion again, so be difficult for accurately obtaining the requirement of predetermined scheme, more can't a feed cut bone stump or the bone piece that (cutting) gets the required angle of operation plan, and doctor's working strength is big.
This utility model provides a kind of double-pole angle adjustable osteotome, and the angle between the two cutter hub chisel edges can be regulated according to the operation needs, can be used for section (cutting) osseous surgery of multiple situation.

This utility model is made of handle of a knife, cutter hub two large divisions.Said handle of a knife is made up of handle 1, nut 2, transposition cover 3 and dress tool post pedestal 4.Be with dress tool post pedestal 4 in the transposition cover 3, the two is the contact that coincide, and dress tool post pedestal 4 can overlap in 3 in transposition and rotate.The outside one end of transposition cover 3 has flange, and there is reticulate pattern in the outside of flange, and the other end has screw thread.Nut 2 be "

" shape, reticulate pattern is carved with in its outside, and there is screw thread the inboard, is foot down.Nut 2 puts from handle 1 end of handle of a knife, the screw thread interlock mutually that 3 outsides are overlapped in its screw thread and transposition.Dress tool post pedestal 4 is "T"-shaped with handle 1 joint, and foot inboard of flange and nut 2 matches under it.Respectively be provided with dress tool post 5 on dress tool post pedestal 4 and the transposition cover 3, dress tool post 5 respectively is provided with two screws 8, and the base portion of cutter hub 6 respectively has two slotted holes along y direction, by two screws 7 cutter hub 6 is fastened on the dress tool post 5 respectively.The vertical sword of two cutter hubs 6 is positioned on the axis of handle of a knife relatively all the time.The design of slotted hole is convenient in order to load and unload (replacing) cutter hub, and cutter hub 6 basilar parts are put forth effort on when being subjected to clashing on the end face of dress tool post pedestal 4 of handle of a knife fully, has got rid of the impact to screw.On the end face of dress tool post pedestal 4, be carved with angle index.Angle between 6 two chisel edges of cutter hub can be regulated as required.Cutter hub 6 can adopt the serial cutter hub of the different width of chisel edge, the different length of vertical sword, different thickness and shape according to the sclerotin of clinical different sizes, length, width, thickness and shape for having the serial cutter hub of chisel edge and vertical sword.
Operating process of the present utility model is: earlier transposition cover 3 covers are sitting on the dress tool post pedestal 4 of handle of a knife, again nut 2 was overlapped handle 1 go with transposition cover 3 on threaded engagement, after tightening, the following flange of dress tool post pedestal 4 is blocked in the foot inboard of nut 2, the upper surface of dress tool post pedestal 4 is then blocked in the bottom surface of the dress tool post 5 on the cover of transposition simultaneously 3, thereby the three is become one.The adjusting of angle is to have two cutter hubs 6 of chisel edge, vertical sword between 6 liang of chisel edges of cutter hub, is fastened on respectively on the dress tool post 5 on dress tool post pedestal 4 and the transposition cover 3, and the vertical sword of two cuttves is positioned on the axis of handle of a knife relatively all the time.When unscrewing nut 2, handle 1 and dress tool post pedestal 4 can relatively rotate with transposition cover 3 together, and two cutter hubs 6 are also along with relatively rotating simultaneously, angle between two chisel edges is changed, after mixing up predetermined angle, fastening nut 2, can make its fixed angle, and then undergo surgery.
Compared with the prior art the utility model owing to two cutter hubs of employing, and can be selected in advance to regulate the feed angle that fixes two cuttves, thereby reduce the feed number of times, increases work efficiency, and alleviates doctor's labour intensity, and greatly improves the accuracy of operation.
