Abstract

The utility model discloses a fracture fixing apparatus, which relates to the technical field of medical instruments for orthopedics departments and comprises a left clamp handle, a right clamp handle and a clamp opening. An inserting shaft is disposed at the tail end of the clamp opening, pores are processed at the front end surfaces of the left clamp handle and the right clamp handle, the rear end of the right clamp handle is hinged with a nut, a jacking iron and a screw rod, a groove is processed at the rear end of the left clamp handle, a plate spring for opening the clamp opening is mounted between the left clamp handle and the right clamp handle, and a bone nail hole is arranged on the clamp opening. In operation, a suitable clamp opening is chosen, accurate fracture reduction can be realized by rotating the nut, the arc-shaped clamp opening is employed to clamp fractured bones, fracture reduction can be achieved by screwing the nut tightly, the next step fixing can be performed when a bone nail is inserted into the bone nail hole on the arc-shaped clamp opening, and the fracture fixing apparatus is not needed to be moved or rotated during operation, thereby shortening operation time, achieving convenient use and small damage to the bones, reducing operational danger and greatly improving operation success ratio of bone reduction.

Description

Fracture fixing apparatus

Technical field

This utility model relates to the orthopaedics technical field of medical instruments, relates in particular to a kind of fracture fixing apparatus.

Background technology

The reduction of the fracture is a great difficult problem in the fracture operation; because human skeleton is hard and have toughness; resetting after the fracture usually can bring very big difficulty to the operation technique person, and resetting after the fracture need assist the fix bone position to make fracture restore the growth of carrying out self-regeneration with nail sometimes.In the operation because the difficulty of the reduction of the fracture, usually be to squeeze into nail respectively at two places of bone fracture earlier, applying strength again on nail resets, if when running into this moment than thin or the skeleton that hardness is not enough, nail destroys skeleton possibly when applying strength, just can not utilize the method for the nail application of force to carry out resetting of skeleton.There is the people that existing reduction of the fracture apparatus is improved for this reason, disclosed by utility model patent designs such as Lan Hai, Wang Hui, that the patent No. is 200820021045.7, name is called fracture fixing apparatus as State Intellectual Property Office on January 21st, 2009, it comprises left side pincers handle, right pincers handle and jaw, the not end of jaw is provided with and inserts axle, processing is porose on left side pincers handle and the right pincers handle front end face, right pincers handle rear end is hinged with nut, top ferrum, screw rod, pincers handle rear end, a left side is processed with a groove, is equipped with between left side pincers handle and the right pincers handle and makes the open leaf spring of jaw; This fracture fixing apparatus can be changed the jaw of different-diameter as required, and utilize lever principle, use the tong-like structure fracture accurately to be resetted by swivel nut, utilize arc vice jaw to clamp the bone of fracture fracture after, screw nut, so just can be earlier with the reduction of the fracture.Its shortcoming is not have bone screw holes on the arc vice jaw, when squeezing into nail, needs sometimes to move or the rotation fracture fixing apparatus, has prolonged operating time.

Summary of the invention

The purpose of this utility model provides and need not in a kind of operation to move or thereby operating time, fracture fixing apparatus easy to use are shortened in rotation.

The technical scheme that this utility model is adopted for achieving the above object is:

A kind of fracture fixing apparatus, comprise left side pincers handle, right pincers handle and jaw, the end of jaw is provided with and inserts axle, processing is porose on left side pincers handle and the right pincers handle front end face, right pincers handle rear end is hinged with nut, top ferrum, screw rod, pincers handle rear end, a left side is processed with a groove, is equipped with between left side pincers handle and the right pincers handle and makes the open leaf spring of jaw, it is characterized in that: have bone screw holes on the described jaw.

Fracture fixing apparatus of the present utility model, on jaw, have bone screw holes, select suitable jaw in the operation earlier for use, by swivel nut fracture is accurately resetted again, utilize arc vice jaw to clamp the bone of fracture fracture then, screwing nut just can be earlier with the reduction of the fracture, and squeezing into that nail advances this moment on the bone screw holes of arc vice jaw is feasible next step fix, need not in the operation to move or the rotation fracture fixing apparatus, thereby shorten operating time, easy to use.Adopt this mode of afterwards beating nail of resetting earlier little, reduce the danger of operation, improve the success rate of operation of bone reduction greatly the damage of skeleton.
