Description
Technical field
This utility model relates to a kind of Orthopedic operation retractor, belongs to bone surgery apparatus.
background technology
At present, how the orthopaedics drag hook using is clinically deposited together with other operating theater instruments, there is no fixing deposit position, and the searching of need to wasting time and energy when use, easily incurs loss through delay opportunity of operation, and places in a jumble easy cross infection, is unfavorable for the clean use of operating theater instruments.It is mainly that the larger tissue of the elasticity such as muscle, ligament is carried out to tractive that bone surgery exposes surgical field of view, and existing surgery tractor is simple in structure, and tractive is comparatively required great effort, and has increased great work difficulty to medical worker.
Utility model content
The purpose of this utility model is to solve that the confusion that above-mentioned prior art exists is put, the deficiency of tractive inconvenience, provides a kind of and is convenient to put, tractive is time saving and energy saving, the Orthopedic operation retractor of assisted surgery illumination.
A kind of Orthopedic operation retractor, comprises handle 1 and torque arm 2, and special character is that torque arm 2 ends are connected with coupler body 3, and coupler body 3 inner sides are provided with projection 4; Torque arm 2 middle and upper parts are provided with fixing hole 5, and locating shaft 6 is installed in fixing hole 5, and torque arm 2 connects sub-arm 7 by locating shaft 6, and sub-arm 7 end faces are 60 ° of inclined-planes, and sub-arm 7 front portions are provided with ring gear 8, and sub-arm 7 front ends are provided with tooth protruding 9; Described torque arm 2 front portions are provided with illuminator 10; Described handle 1 end is provided with hook 14.
When Orthopedic operation retractor uses, by locating shaft 6 is regulated and fixed, adjust the angle between sub-arm and coupler body 3, projection 4, the auxiliary grapple muscular tissue of tooth protruding 9, ring gear 8 increases the frictional force of organizing between sub-arm 7, is more conducive to the grapple of sub-arm 7.And in operation process by illuminator 10 for operation technique person increases brightness, alleviate medical worker's operation easier.After operation, hang in cabinet by linking up with 14, avoid itself and other operating theater instruments to mix storing, to ensure its cleannes.
A kind of improvement project of the present utility model is that described handle 1 is provided with anti-slip veins, increases the frictional force between handle and user, is difficult for slippage, ensures that handle normally uses.
Another kind of improvement project of the present utility model is, described protruding 4 indentations, and the peak-to-peak angle of adjacent teeth is 45 °, under this angle, use coupler body, neither can cause secondary injury to wound, also can hook preferably the position such as muscle, ligament, assist carrying out smoothly of bone surgery.
Another improvement project of the present utility model is, described torque arm 2 front and rear parts are provided with sliding sleeve 11, middle part is provided with elastic force positioning sleeve 12 and locating sleeve 13, when operation is used drag hook, only the aids such as drainage tube need be fixed by elastic force positioning sleeve and locating sleeve, avoid the mixed and disorderly of operative site, be beneficial to normally carrying out of operation.
This Orthopedic operation retractor, is provided with coupler body and sub-arm, the tissue such as wound, muscle ligament is carried out to grapple simultaneously, alleviated operation easier, and the two is respectively equipped with protruding and tooth is protruding, is also provided with ring gear on sub-arm, increased the frictional force between tissue and drag hook, it is convenient, time saving and energy saving to capture.Drag hook is also provided with illuminator, can be operation process and adds brightness, is beneficial to normally carrying out of operation.By hook, Orthopedic operation retractor is hung and put, avoid it to mix with other operating theater instruments and put generation cross infection.
