Description

Congenital dislocation of hip pelvic osteotomy cutter

Technical field

This utility model relates to a kind of bone surgery set, and particularly a kind of congenital dislocation of hip pelvic osteotomy cutter is exclusively used in paci's operation.

Background technology

For the congenital dislocation of hip disease, in orthopaedics is clinical, generally all adopt operative treatment, during operation, adopt the guiding scroll saw that hipbone is cut off by operator.Adopt the disconnected existence of guide line sawing following obviously not enough: the one, to the surrounding tissue damage seriously, easily cause secondary damage; The 2nd, amount of bleeding is more, also to transfuse blood when serious, and hemorrhage many art open countries that easily influences; The 3rd, osteotomy surface is unsmooth, and the angle of osteotomy and position are difficult for grasping accurately; The 4th, the guiding scroll saw is easy-to-draw disconnected or block, and influence the quality and the operative speed of bone piece embedding.The employing cutting knife that also has at present cuts off, but pushes firmly greatlyyer in cut-out, and the feed dynamics is difficult for grasping.

Summary of the invention

The purpose of this utility model is to provide a kind of secondary damage of can avoiding occurring in hip dislocation operation, reduce hemorrhagely as far as possible, and osteotomy surface is smooth, and the feed dynamics is grasped easily, and the hemorrhage congenital dislocation of hip pelvic osteotomy cutter that does not influence the art open country.

For reaching above purpose, the technical scheme that this utility model adopted is: this congenital dislocation of hip pelvic osteotomy cutter, by the location crotch, guide rail, fixing sliding sleeve, the chisel bar, the chisel head constitutes, the fixing location crotch of going up of the front end of guide rail, the fixing chisel head of going up of the front end of chisel bar, the chisel bar is stuck in the guide rail, fixedly sliding sleeve is sleeved on the outside of guide rail and chisel bar, and it is fixing with the guide rail outside, the chisel bar is clamped in the guide rail, the chisel bar is unlikely dislocation in sliding along guide rail, it is characterized in that on the chisel bar, being provided with the propelling tooth, the propelling head of pulling handle is stuck on the propelling tooth of chisel bar, establish hammering device at the propelling headstock end of pulling handle, the chisel head is under the situation that promotes to shear with pressure forward, the effect that has the feed of impacting simultaneously, so that push away when motionless at the chisel head, the available mode that impacts is cut a hole and is got, and also establishes tube chamber in the chisel bar, and the front end of tube chamber is established opening at chisel headstock end, the rear end of tube chamber is at chisel bar tail end opening, and connect suction seat, in operation, if when having the hyperhematosis of going out influence operation art wild, can in time extract blood out, the fixed handle of hand holding handle and fixedly sliding sleeve fix.This utility model is also implemented by following measure: described hammering device, comprise column hammer piece, tubular shell, spring, cam, handsetting gear, poke rod, fixing head, extension spring constitutes, tubular shell is fixed on the fixed handle by fixing head, spring is contained in the tubular shell, front end withstands on the column hammer piece, the front end of poke rod is established ratchet, ratchet is stuck on the handsetting gear, cam is coaxial with handsetting gear, and be fixed on the upper end of fixed handle, when pulling poke rod, handsetting gear rotates, the drive cam rotates, column hammer piece compression spring is stirred at the tip of cam, and when the cam tip turned over poke rod, spring firmly, make column hammer piece impact the propelling head, thereby make chisel head cutter get sclerotin; Described chisel bar is that square steel is made, and front end is flat, makes an integral body with the chisel head; Described guide rail is that "  " shape steel disc is made, and front end is flat, is made as an integral body with the location crotch, and the slip teeth of also setting up defences in crotch inboard, location is with fixing hipbone face effectively.When using this utility model, earlier the chisel bar is retracted, the location crotch is separated and the suitable distance of bone width with the chisel head, fix the lower edge of ilium with the location crotch, chisel head blade is placed on the bone ridge of ilium upper limb, hold with middle finger, the third finger, little finger of toe then and pull handle and promote the chisel bar forward, be in one's hands when moving firmly, prevent to overexert, the reuse forefinger is held the poke rod of hammering device, and the chisel head is cut a hole into, progressively cuts off ilium, if hemorrhage more, then injector syringe be connected on the suction seat of chisel bar and extract out.

The beneficial effects of the utility model are: compare with the apparatus that the hip dislocation operation of present use is used, because integrating location, crush-cutting, cutter cuts, aspirates, make the ilium section smooth complete, make embedding bone piece firmly stable, the art open country is clear, reduces operating time, has avoided secondary damage simultaneously, overcome hemorrhage shortcoming, reduced misery to the patient.
