Abstract
The utility model provides a convenient adjusting type retractor for orthopaedics and belongs to the field of medical equipment. The retractor comprises two retraction arms which are arranged on a screw rod, and one end of the screw rod is provided with a hand screwing handle; and each retraction arm is connected with an extension arm by a connecting arm, and the connecting arm and the extension arm are in threaded connection. Compared with the retractor adopting the prior art, the retractor has the characteristics of reasonable design, simple structure and the like, is convenient to use, and can realize good traction of bones, fully expose the surgery field of an operation and guarantee a smooth orthopaedic surgery.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the easy accent type retractor that a kind of specifically orthopaedics is special-purpose.
Background technology
Aspect orthopaedics; The treatment or the difficulty of operation for skeleton are also quite high; All be to lean on dislocation double or that many humans manpower will be fractured to draw back again to reset in the fracture fixation operation in the past; This sample loading mode wastes time and energy very much, but also increases misery even also can in operation, meet accident to the patient; The medical skill of present stage is generally all being assisted complete operation by some operating theater instruments, especially adopts resetting that nail comes that interoperation fractures.But the selection of squeezing into a little of nail also has quite high requirement.Implementing that skeleton retracts or during tractive, the drawing arm position of prior art retractor generally all is changeless, skeleton can not get good tractive; And obstruct the view, hinder operation to carry out, and when using retractor, often occur the not parallel of retractor drawing arm easily; Cause bone injury, and it is limited to retract area, is difficult for making bone to turn up; Make that the effect that retracts is not ideal enough; A lot of organs can not well be exposed in doctor's the surgical field of view, and then damage the tissue of fracture, cause unnecessary damage.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, provides a kind of orthopaedics simple in structure with being prone to accent type retractor.
The technical scheme of this utility model realizes by following mode:
Orthopaedics is with being prone to accent type retractor; Its structure comprises two drawing arms, and said two drawing arms are installed on the leading screw, and an end of this leading screw is provided with the hand-screw handle; Said drawing arm is connected with extension arm through a linking arm, and it is fixing to be threaded between said linking arm and the extension arm.
The outer wall of said extension arm is provided with jagged edges.
The beneficial effect that this utility model is compared with prior art produced is:
A kind of orthopaedics of this utility model has simple in structure, easy to use, characteristics such as be skillfully constructed with easy accent type retractor, and this drawing arm that is arranged so that through extension arm is effectively prolonged, position that so just can the easy adjustment drawing arm; It is wild fully to expose the operation art, helps operation to carry out, and on drawing arm, is fixed with a plurality of plates that retract simultaneously; Retract enlarged areas; Tractive is satisfactory for result, because extension arm is provided with jagged edges, effectively holds when retracting and retracts the position; Avoided reducing the probability that skeleton sustains damage to the damage of bone with to the destruction of muscular tissue.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model.
Labelling in the accompanying drawing is represented respectively:
1, hand-screw handle, 2, drawing arm, 3, leading screw, 4, linking arm, 5, extension arm, 6, jagged edges.
The specific embodiment
Below in conjunction with accompanying drawing the orthopaedics of this utility model is done following the detailed description with being prone to accent type retractor.
Shown in accompanying drawing 1; This orthopaedics is with being prone to accent type retractor; Its structure comprises two drawing arms 2, and said two drawing arms 2 are installed on the leading screw 3, and an end of this leading screw 3 is provided with hand-screw handle 1; Said drawing arm 2 is connected with extension arm 5 through a linking arm 4, and it is fixing to be threaded between said linking arm 4 and the extension arm 5.
The outer wall of said extension arm 5 is provided with jagged edges 6.
