Abstract
This utility model provides a kind of anti-dazzle laborsaving Orthopedic operation retractor, comprise drag hook coupler body, one end of drag hook coupler body is fixedly connected with drag hook torque arm, at the back side of drag hook torque arm, granular projection is set, it forms diffuse-reflectance after the projection light of the operation light in operation process can be made to be irradiated to above-mentioned granular projection, prevents operating lamp light from after the reflection of drag hook polished surface, affecting the cooperation of assistant.This utility model solves light of performing the operation in operation process and form dazzle interference phenomenon after the reflection of drag hook polished surface, and also can increase frictional force due to the existence of granular projection, reaches assistant's labour-saving object in the process using drag hook.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of operating theater instruments, the pulling device of particularly a kind of orthopaedics routine application, the laborsaving Orthopedic operation retractor of anti-dazzle.
Background technology
Surgery tractor unavoidably needs to use in bone surgery process.Orthopedic operation retractor general is at present stainless steel, possesses the features such as counter-bending, and surface is polishing.But surface finish process can reduce unrestrained transmitting, thus cause the dazzle interference phenomenon in a direction.In operation process, when assistant uses surgery tractor, because the phenomenon of dazzle interference often has influence on the observation of assistant to surgical field of view after the burnishing surface reflection of operation light through drag hook surface, have influence on the cooperation of operation.Current common processing mode is the reflection preventing operation light at drag hook surface coverage sterile gauze.But such a process increases surgical operation step, add the risk of postoperative infection; Waste the use of sterile gauze, add medical treatment and consume.
Utility model content
The purpose of this utility model is exactly for above-mentioned weak point, and according to irreflexive principle, namely light can disorderly to pollodic phenomenon after being radiated at the coarse surface of object.This direction-free reflection from any angular observation of reflecting surface homonymy to the incident illumination of brightness deterioration, thus can weaken dazzle interference phenomenon.
The laborsaving Orthopedic operation retractor of a kind of anti-dazzle, comprise drag hook coupler body, one end of drag hook coupler body is fixedly connected with drag hook torque arm, at the back side of drag hook torque arm, granular projection is set, it forms diffuse-reflectance after the projection light of the operation light in operation process can be made to be irradiated to above-mentioned granular projection, prevents operating lamp light from after the reflection of drag hook polished surface, affecting the cooperation of assistant.
Further, the length arranging granular projection accounts for 2/3 of whole drag hook torque arm length, avoids the long tissue of granular projection to tractive to have an impact.
Granular projection is arranged to the back side of the general drag hook torque arm of orthopaedics, makes operation light out-focus after the reflection of granular projection, form astigmatism, avoid operation light to form dazzle interference phenomenon after drag hook surface reflection, affect the surgical field of view of assistant.Also can increase frictional force after the back side of this surgery tractor arranges granular projection, make assistant in the process using drag hook, play labour-saving effect.
Accompanying drawing explanation
Fig. 1 is the laborsaving Orthopedic operation retractor structural representation of anti-dazzle.
Fig. 2 is the close-up schematic view of granular projection in Fig. 1.
Wherein: 1 drag hook coupler body, 2 drag hook torque arm, 3 granular projections, 4 length that granular projection is set, the projection light of 5 operation light, 6 diffuse-reflectance.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in detail further, but embodiment of the present utility model is not limited thereto.
The laborsaving Orthopedic operation retractor of a kind of anti-dazzle, comprise drag hook coupler body 1, one end of drag hook coupler body 1 is fixedly connected with drag hook torque arm 2, at the back side of drag hook torque arm 2, granular projection 3 is set, it forms diffuse-reflectance 6 after the projection light 5 of the operation light in operation process can be made to be irradiated to above-mentioned granular projection 3, prevents operating lamp light from after the reflection of drag hook polished surface, affecting the cooperation of assistant.The length 4 arranging granular projection accounts for 2/3 of whole drag hook torque arm length, avoids the long tissue of granular projection to tractive to have an impact.
The back side of drag hook torque arm 2 arranges the rear assistant of granular projection 3 can also increase skin-friction force in the process using drag hook, makes assistant in use reach labour-saving object.The laborsaving Orthopedic operation retractor of this anti-dazzle adopts stainless steel material to make, in operation process, assistant holds drag hook torque arm 2 position, drag hook coupler body 1 location contacts tissue, the granular projection 3 of operation light through drag hook torque arm 2 back side forms diffuse-reflectance 6, avoids dazzle interference phenomenon; Simultaneously because the existence of granular projection 3 adds the frictional force at assistant and drag hook torque arm 2 position, reach labour-saving object.
Claims (2)
1. the laborsaving Orthopedic operation retractor of anti-dazzle, it is characterized in that, comprise drag hook coupler body (1), one end of drag hook coupler body (1) is fixedly connected with drag hook torque arm (2), at the back side of drag hook torque arm (2), granular projection (3) is set, it can make the projection light (5) of the operation light in operation process be irradiated to above-mentioned granular projection (3) and form diffuse-reflectance (6) afterwards, prevents operating lamp light from after the reflection of drag hook polished surface, affecting the cooperation of assistant.
2. the laborsaving Orthopedic operation retractor of anti-dazzle according to claim 1, it is characterized in that, the length (4) arranging granular projection accounts for 2/3 of whole drag hook torque arm (2) length, avoids the long tissue of granular projection to tractive to have an impact.
