Abstract
The utility model relates to a fracture operation repositor with aiming function, which is provided with a rod body, wherein one end of the rod body is made into a hook, and the other end is provided with a bone clamping hook used for fixing the upper end of the fixing rod body and an outside thread section of an aiming device; the aiming device comprises a drill guider and nuts; one end of the drill guider is sleeved on the outside thread section of the rod body; the nuts play a locking role for the drill guider; one end of the drill guider is provided with a rod sheath, and the other end and the middle vicinity are provided with a plurality of through holes for a drill penetrating through; one end of the bone clamping hook is provided with the rod sheath, and the other end is made into a hook shape which is opposite to the hook of the rod body. The utility model can forcibly maintain the reposition state of fracture blocks during operation, and is also provided with the aiming device. A most suitable drilling position can be accurately selected during operation, and the damage to tissues can be effectively reduced. A front column and a rear column of acetabular bones can be reinforced and fixed by cancellous screws through the fracture operation repositor which can reduce the exertion of other inner fixing apparatuses, thereby the expenses of patients can be reduced.
Description
Technical field this utility model relates to medical device, relates in particular to a kind of fracture operation repositor with aiming function.
Background technology
Reset in the fractures process be one must through program, baroque bone reduction is difficult point, especially a hipbone, anatomical reduction and strong internal fixation are crucial, and resetting of fracture of acetabulum is different from the fracture at other positions, mainly relies on apparatus to reset.For the fracture of acetabulum that relates to twin columns, adopt a kind of hook-shaped positor clinically at present, this positor needs the assistant firmly to lift more, two sclerites could be reset to together, and then select suitable position boring.There is following shortcoming in this positor: apparatus volume is big, needs peeling off just of more soft tissue can lay reduction instrument; Waste assistant muscle power; Be unfavorable for that stable keeping resets; Occupy the operation technique space, the operation of influence operator; Reduction instrument will directly threaten sciatic nerve in case slide.
Summary of the invention
The purpose of this utility model provides a kind of fracture operation repositor with aiming function, reach when operation little to the damage of tissue, can keep reset mode effectively and sclerite is carried out accurate location drilling, purpose easy and simple to handle.
The technical scheme that this utility model adopted is: a kind of fracture operation repositor with aiming function, it is characterized in that having the body of rod that an end is made crotch, the other end of the body of rod is shaped in order to the card hamulus of hamate bone of fixed core upper end installation and the external thread section of sighting device.
Described sighting device comprises that an end is sleeved on the bit guide of body of rod external thread section and it is played the nut of locking action.
One end of described bit guide is shaped on the bar cover, is shaped on a plurality of through holes that supply drill bit to run through near the other end and the centre.
One end of described card hamulus of hamate bone is shaped on the bar cover, and the other end is made relative with body of rod crotch hook-shaped.
The thickness of described bar cover is greater than the thickness of card hamulus of hamate bone.
This utility model can be kept the reset mode of sclerite effectively and sclerite is pressurizeed in operation, also be provided with sighting device on the apparatus, can accurately select only bore position during operation, can effectively reduce damage to tissue, just can carry out strong fixing by this apparatus to post before and after the acetabular bone with cancellous bone screw, can reduce the utilization of other internal fixation devices, improve the operation quality, thereby can reduce patient's expense, this utility model also has characteristics such as simple in structure, easy to operate.

The specific embodiment
As shown in Figure 1, this utility model comprises the body of rod 1, card hamulus of hamate bone 2, and an end of the body of rod 1 is made crotch 12, and the other end is shaped on external thread section 11; Card hamulus of hamate bone 2 is made tabular, the one end is made the hook formation that cooperates with crotch 12, and the other end is shaped on bar cover 21, will block hamulus of hamate bone 2 and be enclosed within on the body of rod 1 and can axially be free to slide, the thickness of this end bar cover 21 makes to have good stable when this apparatus is controlled sclerite greater than the thickness of card hamulus of hamate bone 2; Be screwed with two and external thread section nut engaged 4 on the external thread section 11 of card hamulus of hamate bone 2 tops, be with bit guide 3 between two nuts 4 and it is played locking action, one end of bit guide 3 is shaped on bar cover 31, is shaped on 3 through holes 32 that supply drill bit 5 to pass near the other end and the centre.
The sclerite that hooks hipbone with card hamulus of hamate bone 2 and crotch 12 during operation coincide it to reset, the bar cover 21 that the nut 4 of screwing on then compresses card hamulus of hamate bone 2 makes this apparatus control sclerite effectively and sclerite is pressurizeed, refilling bit guide 3 and distaff body 1 rotates and makes one of through hole 32 aim at only specific region on the sclerite, make drill bit 5 less to the damage of tissue in this zone boring, then tighten 4 pairs of bit guides 3 of another nut and lock, hole at selected 5 pairs of sclerites of through hole 32 usefulness drill bits at last.
