Abstract
The utility model pertains to the field of orthopaedic medical apparatus and technology, especially as a clavicle fracture reduction pincers, including two pincer-form arms and a rotation axis for connecting two pincer-form arms, which is characterized in that the front ends of two pincer-form arms are shaped in semi-lip rounds and can be combined to form a squared jaw, the jaw is connected with a handle of the pincer-form arm at a certain angle, the rear of the pincer-form arm has the rack with interlocked inverted teeth, the back end of the pincer-form arm is provided with an arc palm trim support which fits with the palm trim. The handle of the pincer-form arm is shaped as an overstriking arc, and the outer-surface has embossed with inside caved. The handle and the squared jaw form a bended pincer-form structure. The pincer-form arm and the rotation axis are connected through a dowel ensuring the rotation. The pincers has the advantages below: the squared jaw fits with the appearance of the clavicle; the handle is shaped like an overstriking arc which reduces the pressure to the pincers holder from the handle during the use; the back end of the pincer-form arm is provided with the arc palm trim support which fits with the palm trim of the pincers holder for facilitating the strength of the pincers holder.
Description
Technical field
This utility model belongs to orthopaedic medical treatment utensil technical field, particularly a kind of clavicular fracture reduction forceps.
Background technology
In clavicular fracture treatment, after being used for fixing the clavicular fracture broken ends of fractured bone and resetting, just various internal fixation are exercised in no longer displacement.The apparatus that is used for fixing clavicular fracture is most important for success rate of operation, does not still have a kind of clavicle reduction forceps of answering hands at present.Utility model patent ZL00267961.2 " clavicular fracture break reduction fixture device " proposes a kind of technical scheme: two arm front ends be respectively multiple tooth relatively mutually in crooked front arc tooth plate and rear arc tooth plate, two arm ends are the handles of holding of straight shape, one fixing pintle hook lock device is arranged at the middle part of two arms, and front end is the gooseneck shape.Find following point in actual the use:
1, the design of jaw is too complicated.Multiple tooth shape design makes soft tissue injury excessive;
2,, in the implementation and operation process, can produce bigger pressure and make and hold the pincers hands and be subjected to the pincers injury the person's that holds pincers hands because to hold handle thinner.
3, hold the terminal oriented interior sweep of handle, the person pulls at moving caliper to be unfavorable for holding pincers;
4, a fixing pintle hook lock device is arranged at the middle part of two arms, it is convenient inadequately to use.
Summary of the invention
The purpose of this utility model provide a kind of rational in infrastructure, easy to use, reduce patient's soft tissue injury and can not injure the clavicular fracture reduction forceps of the person's that holds pincers hands.
The purpose of this utility model realizes by following technical proposals.
According to clavicular fracture reduction forceps of the present utility model.Comprise two pincerlike arms and connect the turning cylinder of two pincerlike arms, the front end that it is characterized in that described two pincerlike arms is half degree of lip-rounding and combines the square jaw of formation, the handle of holding of this square jaw and pincerlike arm is bent angle shape and is connected, pincerlike arm posterior medial is provided with the pawl buckle teeth bar that is meshing with each other, and pincerlike arm rear end is provided with and slaps the arc palm edge that edge portion matches and leans on.
The handle of holding of described pincerlike arm is overstriking circular arc, and outer surface is provided with embossing, and the inboard is recess.
Hold handle and the square jaw of described pincerlike arm form angle nose pliers shape structure.
Doing rotatable riveted joint between described two pincerlike arms and the turning cylinder is connected.
Of the present utility model have a following advantage:
1, square jaw and clavicle profile match;
2, hold handle and be overstriking circular arc, outer surface is provided with embossing, and the inboard is recess, makes the weight of caliper lighter, in use, has increased and has held the pincers hands and hold frictional force between the handle, has alleviated and has held handle to holding the pressure that clamps hands;
3, pincerlike arm rear end is provided with and slaps the arc palm edge that edge portion matches and leans on, and matches with the palm edge of holding the pincers hands, is convenient to hold the pincers hands firmly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in Figure 1, according to clavicle positioning clamp of the present utility model, comprise two pincerlike arms 3 and connect the turning cylinder 2 of two pincerlike arms, the front end that it is characterized in that described two pincerlike arms 3 is half degree of lip-rounding and combines the square jaw 1 of formation, the handle 4 of holding of this square jaw 1 and pincerlike arm 3 is bent angle shape and is connected, pincerlike arm 3 posterior medials are provided with the pawl buckle teeth bar 5 that is meshing with each other, and pincerlike arm rear end is provided with and slaps arc palm edge that edge portion matches by 6.
The handle 4 of holding of described pincerlike arm is overstriking circular arc, and outer surface is provided with embossing, and the inboard is recess 7.
The handle 4 of holding of described pincerlike arm forms angle nose pliers shape structure with square jaw 1.
Doing rotatable riveted joint between described two pincerlike arms 3 and the turning cylinder 2 is connected.
Of the present utility model have a following advantage: square jaw 1 matches with the clavicle profile; Hand Lever 4 is overstriking circular arc, and outer surface is provided with embossing, and the inboard is recess 7, the weight of caliper Measure lighter, in use, alleviated hold handle to hold pincers hand pressure; Pincerlike arm rear end Be provided with the arc palm by 6, match with the palm edge of holding the pincers hand, be convenient to hold the pincers hand firmly.
