Abstract

The utility model provides a pliers type fracture fixing device with double arms, which is composed of a pliers section, a clamping block and a hand-holding hole. The utility model is characterized in that the cambered double arms are arm ears are connected with the pliers section by movable joints, and the cambered double arms are made of two rectangular steel plates whose radians are 90 DEG. The utility model is suitable for various kinds of fracture which needs the inner fixation with steel plates and screw nails. The utility model has the advantages that the utility model reduces the time of operations and tissue damage, reduces the chance of haemorrhage and infection, reduces the pain and the economic burden of patients and brings convenience for operative surgeons, etc.

Description

Both arms jaw type fracture fixing apparatus

This utility model is a medical mechanical domain, the both arms jaw type fracture fixing apparatus of the synthetism that is specially adapted to fracture.

At present, in the orthopaedics clinical position, owing to reasons such as wound cause that the long bone of limbs fracture is more common, a wherein big part needs open reduction, steel plate screw internal fixation treatment.We appear fracture site in operation process, and after the manual reduction satisfaction, implant plate is twisted in the screw process in boring, and the displacement once more of fracturing often easily takes place, and for operation causes difficulty operating time are prolonged, and the patient is produced a series of harmful effects.What adopted in the art now is the three-jaw fracture fixing apparatus, but because of itself existing more drawback to make it use limitation.At first fixedly impetus is less or short for three-jaw, and some comminuted fracture, long diagonal, fracture line are all had certain difficulty than fixation of fractures such as length.And two pawls of three-jaw holder need stretch to the offside of otch and bone, easily produce the offside tissue injury of otch and bone, as important blood vessels, and nerve etc.Secondly tighten up the holder purpose and expend time in because of adopting the spiral button to rotate to reach, in its process, still make the fracture redisplacement of the success that is difficult for resetting probably.

Task of the present utility model is at the problems referred to above, and a kind of miscellaneous fracture that needs the steel plate screw internal fixation that is applicable to is provided, and can reduce operating time and tissue injury, reduces the both arms jaw type fracture fixing apparatus of hemorrhage and infection chance.

This utility model is finished in the following way:

In art, fully expose otch, the cleavage fracture broken ends of fractured bone, manual reduction reaches promising result, institute's fixation steel plate is implanted fracture, right-handed big mother refers to that holding hand hole [6] with middle finger opens holder, is adjacent to the backbone of the back that resets with arc both arms [1], and arm ear [2] is that steel plate passes through the place just, close then and fasten device block [5], the fastening backbone of arc both arms then, the arm ear blocks steel plate and makes it fixing, holder is clamped portion [4] Movable joint [3] push a side (left side or right) to, can be in opposite side (a right or left side) operation, boring and twist screw, treat that whole screws fixedly secure steel plate and bone after, take off holder, the inspection otch is no abnormal, the layer-by-layer suture otch.

This utility model is applicable to the miscellaneous fracture that needs the steel plate screw internal fixation, has the operating time of minimizing and tissue injury, reduces hemorrhage and infection chance, minimizing patient suffering and financial burden, more convenient characteristics such as surgical doctor.

Fig. 1 is this utility model overall structure figure.

Below in conjunction with accompanying drawing the utility model is described in detail:

A kind of by pincers section [4], the Double-arm clamp type fracture that block [5] hand hole [6] forms is solid Decide device, it is characterized in that: arc both arms [1] and arm ear [2] are with turning joint [3] together Pincers section [4] connects, and arc both arms [1] are to be 90 to spend the rectangle steel plates and make with two radians, Its brachium is 20mm-200mm, the wide 5mm-50mm of arm.

Embodiment:

Arc both arms [1] are to be that 90 degree rectangle steel plates are made with two radians, and its brachium arm is wide can to adopt different size according to the different people (adult, child) and the different parts (upper limb, lower limb) of limbs.As adult cadaver lower limb: femoral shaft brachium 100mm-150mm, the wide 15mm-25mm of arm; The dried brachium 80mm-130mm of tibia, the wide 15mm-25mm of arm.Adult upper extremities specimens: the dried brachium 40mm-80mm of humerus, the wide 10mm-20mm chi of arm radius brachium 30mm-60mm, the wide 10mm-20mm of arm.Child's lower limb femoral shaft brachium 50mm-100mm, the wide 10mm-20mm of arm.

Claims

1, the both arms jaw type fracture fixing apparatus a kind of by pincers portion [4], that block [5] hand hole [6] is formed is characterized in that: arc both arms [1] and arm ear [2] are to connect with pincers portion [4] with Movable joint [3].

2, both arms jaw type fracture fixing apparatus as claimed in claim 1 is characterized in that arc both arms [1] are is that 90 degree rectangle steel plates are made with two radians.

3, both arms jaw type fracture fixing apparatus as claimed in claim 1, the brachium that it is characterized in that arc both arms [1] is 20mm-200mm, the wide 5mm-50mm of arm.
