Abstract
The present invention provides a kind of operation retractors, the connection retracted between head and semi-clamp is changed to be hinged by crank pin by the technical solution by being fixedly connected for the prior art, so that upper and lower pivot angle can be realized by retracting head, so that retractor is easier to be fixed with different angle；While the body fluid that the present invention can ooze out edge in the conduction stick for retracting the addition of head outer rim play guiding function, to avoid body fluid along traction head and the excessive extravasation of wound contact position.The present invention realizes technique effect outstanding by relatively simple technological improvement, and cost is relatively low, is easily achieved, and has good industrialization value.
Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of operation retractor.
Background technology
Retractor is also known as drag hook, to retract tissue, appears surgical field of view, convenient for detecting and operating, can be divided into hand-held drawing
Two class of hook and self-retractor.There is the specification of various different shapes and size, can be needed to select suitable drag hook according to operation.For
Field range requires the selectable retractor classification of larger operation more various, and for Minimally Invasive Surgery, retractor makes
To meet the needs of surgical field of view with one side, it is often more important that should avoid injuring wound excessive.
Since Minimally Invasive Surgery equally need to execute the operations such as notch, traction to tissue, can also one be formed to epidermis
Fixed damage.The operation retractor of the prior art itself is not fixed easily after adjusting appropriate angle, and slightly shaking may be right
The angle of traction impacts；It is contacted in addition, the operation retractor of the prior art generally forms line with its edge with notching edge,
Therefore blood, the tissue fluid etc. in tissue are easy to ooze out from contact position.
Invention content
The present invention is directed to the technological deficiencies for the prior art, provide a kind of operation retractor, to solve in the prior art
Operation retractor is not easy the technical issues of fixed position, while solving operation retractor in the prior art and wound contact position body
Liquid is easy the problem of exudation.
To realize that the above technical purpose, the present invention use following technical scheme：
A kind of operation retractor, including the first semi-clamp, the second semi-clamp, articulated shaft, hand-held part, traction head, tight latch mechanism,
In the first semi-clamp and the second semi-clamp it is hinged by articulated shaft, in the first semi-clamp and the second semi-clamp lower end respectively there are one hand-held part,
First semi-clamp and the second semi-clamp upper end respectively there are one retracting head, it is described retract it is arc-shaped, tight latch mechanism be located at the first semi-clamp with
Second semi-clamp angle position, to fixed or adjust included angle between the first semi-clamp and the second semi-clamp, it is characterised in that：Also wrap
Include crank pin and conduction stick, two retract heads by two crank pins respectively with the first semi-clamp and the second half clipper joints, conduction stick
It is fixedly connected on the angle of the plane where retracting head shapes and retracts head outer rim, the conduction stick has several, leading
Beginning outer rim is evenly distributed.
Preferably, the spherical shape in conduction stick end position.
Preferably, several conduction sticks respectively between distance be not more than 0.5cm.
Preferably, a diameter of 0.3~0.5cm of the conduction stick.
The connection retracted between head and semi-clamp is changed to be hinged by crank pin by the present invention by being fixedly connected for the prior art,
So that upper and lower pivot angle can be realized by retracting head, so that retractor is easier to be fixed with different angle；This hair simultaneously
It is bright retract head outer rim addition conduction stick can to edge ooze out body fluid play guiding function, to avoid body fluid along
Retract head and the excessive extravasation of wound contact position.
In optimal technical scheme：Limit the upper and lower end of conduction stick as spherical surface be in order to avoid end excessively it is sharp to wound
Secondary injury caused by mouthful；It limits the distance between conduction stick and should not be too large and be on the one hand to ensure that there is no blind area, draw
Stream effect is more abundant, while can effectively ensure that the wound being stretched is substantially rounded, smaller to the injury of wound；Limit drainage
The conduction stick that stick diameter allows for the diameter range within the scope of 0.3~0.5cm is unlikely to excessive sharp while drainage
Relatively fully.
The present invention realizes technique effect outstanding by relatively simple technological improvement, and cost is relatively low, is easily achieved,
With good industrialization value.
