Abstract
The utility model discloses a pair of orthopedic distraction pincers. The pair of orthopedic distraction pincers comprises an upper pincer body and a lower pincer, which are hinged to each other, wherein a plurality of cone-shaped burrs are arranged at the front ends of both the upper pincer body and the lower pincer body; two nuts are arranged at the tail ends of both the upper pincer body and the lower pincer body, and are connected via a screw rod; a rotary handle is arranged on the screw rod. Positive threads and inverted threads are formed in the screw rod, the cone-body burrs are arranged at the front ends of the pincer bodies, and the area of contact between the pincer bodies and a physical body is increased, as a result, the pincer bodies are difficult to slide out of the physical body; when the pair of distraction pincers are used, the rotary handle arranged on the middle part of the screw rod is rotated to enable that the pincers bodies quickly stretch out and draw back, so that the use is convenient; the telescopic rotary handle is stretched and then propped at a wound, the whole pincer bodies are cone-shaped, the fixation is firm, slip down is difficult, the number of medical staff is decreased, and wide view facilitates observation, accordingly, the medical staff's working difficulty is lowered, the quality of surgery is guaranteed, and the use is ideal; the cone-shaped burrs arranged at one end of the telescopic rotary handle increase the area of the contact between the telescopic rotary handle and the physical body, and enables that telescopic rotary handle is unlikely to slip down.
Description
Technical field
This utility model belongs to medical instruments technical field, particularly a kind of orthopaedics distraction forcep.
Background technology
At present, in bone surgery, often with drag hook, realize the open of surgical field of view clinically, orthopaedics operation retractor is mainly by torque arm, the prominent composition of tooth of coupler body and coupler body lower end, existing drag hook is general only by the prominent fixation that in use rises of monodentate, due to the tissue that the elasticity such as ligament are larger that is mostly of bone surgery institute tractive, only have a tooth prominent fixing and insecure, be easy to slippage, medical worker exposes surgical field of view with the torque arm of hands tractive simultaneously, bone surface ligament, muscle is abundanter, make traction process very painstaking, not only time-consuming but also require great effort, to medical worker, increased work difficulty, thereby cannot guarantee the quality of operation, result of use is undesirable.
If the patent No. is 201220144897 disclosed a kind of orthopaedics operation retractors, it is characterized in that: comprise that torque arm, coupler body, pull handle, depression, tooth are dashed forward, ring gear, described torque arm rear portion is provided with pull handle, described torque arm front portion is provided with coupler body, described coupler body front portion is provided with ring gear, it is prominent that described coupler body front end is provided with tooth, and described pull handle is provided with depression, and described depression adapts with finger tripe size.Its weak point is: need to be with pulling while 1) using, and traction process is very painstaking, not only time-consuming but also require great effort, and has increased work difficulty, thereby cannot guarantee the quality of operation to medical worker, and result of use is undesirable.2) to strut wound, just must use two above-mentioned hooks that pull, need to increase medical worker, operating-table narrow space own, people is many can cause the wound visual field to be not easy to observe, thereby has increased medical worker's work difficulty, the quality that cannot guarantee operation, result of use is undesirable.
Utility model content
This utility model, for prior art above shortcomings, provides a kind of orthopaedics distraction forcep, easy to use, without medical worker, pulls, and can strut wound, and distraction forcep fixation is not easy landing, fully exposes surgical field of view, thereby improves operation quality.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of orthopaedics distraction forcep, comprise upper clamp and hinged lower clamp with it, the front end of described upper clamp and lower clamp is provided with some tapered thorns, the tail end of described upper clamp and lower clamp is provided with nut, between two nuts, by screw rod, connect, on described screw rod, rotary handle is set.
Described screw rod arranges rotary handle on centre.
Described rotary handle adopts telescopic rotary handle, and this telescopic rotary handle end arranges tapered thorn.
On described screw rod, graduation mark is set.
Adopt the orthopaedics distraction forcep of such scheme due to positive and negative silk being set on screw rod, at the front end of caliper, be provided with some tapered thorns, increased and human body contact area, increasing friction force, makes it be not easy landing; Screw rod arranges rotary handle on centre, during use, rotates rotary handle, and caliper quick-expansion is easy to use; Telescopic rotary handle is stretched, be supported on wound, caliper entirety is tapered, and fixation is not easy landing, and has reduced medical worker, and the wound visual field is large easily to be observed, and has reduced medical worker's work difficulty, guarantees the quality of operation, result of use ideal; This telescopic rotary handle end arranges tapered thorn, has increased and human body contact area, and increasing friction force, makes it be not easy landing.By certain ratio, calculate, graduation mark is set on screw rod, be convenient for measuring wound data.Therefore, this utility model is simple and practical, time saving and energy saving, easy to operate, has shortened operating time, has reduced doctor's burden of performing the operation, and surgical risk is reduced, and has good promotion and application and is worth.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described further:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of orthopaedics distraction forcep, comprise upper clamp 2 and hinged lower clamp 3 with it, the front end of described upper clamp and lower clamp is provided with some tapered thorns 1, the tail end of described upper clamp and lower clamp is provided with nut 5, between two nuts 5, by screw rod 4, connect, on described screw rod 4, rotary handle 6 is set.Described screw rod arranges rotary handle 6 on 4 centres.Described rotary handle 6 adopts telescopic rotary handle, and this telescopic rotary handle end arranges tapered thorn.
Adopt the orthopaedics distraction forcep of such scheme due to positive and negative silk being set on screw rod, at the front end of caliper, be provided with some tapered thorns, increased and human body contact area, increasing friction force, makes it be not easy landing; Screw rod arranges rotary handle on centre, during use, rotates rotary handle, and caliper quick-expansion is easy to use; Telescopic rotary handle is stretched, be supported on wound, caliper entirety is tapered, and fixation is not easy landing, and has reduced medical worker, and the wound visual field is large easily to be observed, and has reduced medical worker's work difficulty, guarantees the quality of operation, result of use ideal; This telescopic rotary handle end arranges tapered thorn, has increased and human body contact area, and increasing friction force, makes it be not easy landing.By certain ratio, calculate, graduation mark is set on screw rod, be convenient for measuring wound data.Therefore, this utility model is simple and practical, time saving and energy saving, easy to operate, has shortened operating time, has reduced doctor's burden of performing the operation, and surgical risk is reduced, and has good promotion and application and is worth.
