Abstract
The invention provides a surgical retractor. The technical scheme includes that the fixed connection between retracting heads and semi-pincers in the prior art is changed by the way that the retracting heads are hinged to the semi-pincers through curved arms, thus the retracting heads can swing to form upper swing angle and lower swing angle, and then the retractor is easy to be fixed at different angles. Drainage rods added at the outer edges of the retracting heads have effect of guiding body fluid exuded from the edges to prevent the body fluid from excessively exuding outwards along contact positions of the retracting heads with wounds. Excellent technical effect is achieved by relatively simple technical improvement; the surgical retractor is low in cost, easy to implement and high in industrialization value.
Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of operation retractor.
Background technology
Retractor, also known as drag hook, in order to retract tissue, appears operating field, it is simple to detects and operates, and can be divided into hands
Hold drag hook and self-retractor two class.There is the specification of various difformity and size, can need to select to close according to operation
Suitable drag hook.Field range is required that bigger operation selectable retractor classification is more various, and for micro-
For invasive procedures, the needs using on the one hand surgical field of view to be met of retractor, it is often more important that should avoid
Excessive to wound injury.
Owing to tissue execution otch, retract etc. need to be operated by Minimally Invasive Surgery equally, the most also can be to epidermis shape
Become certain damage.The operation retractor of prior art self is not fixed easily after adjusting suitable angle, slightly
Rock it is possible to the angle retracted is impacted；Additionally, the operation retractor of prior art is generally with its edge
Forming linear contact lay with notching edge, the most in-house blood, tissue fluid etc. are easily oozed out from contact position.
Summary of the invention
It is contemplated that for the technological deficiency of prior art, it is provided that a kind of operation retractor, to solve existing skill
In art, operation retractor is difficult to the technical problem of fixed position, solves operation retractor and wound in prior art simultaneously
The problem that mouth contact position body fluid easily oozes out.
For realizing above technical purpose, the present invention by the following technical solutions:
A kind of operation retractor, including the first semi-clamp, the second semi-clamp, jointed shaft, Handheld Division, retracts head, tightly
Latch mechanism, wherein the first semi-clamp and the second semi-clamp are hinged, in the first semi-clamp and the second semi-clamp lower end by jointed shaft
Be respectively arranged with a Handheld Division, be respectively arranged with one in the first semi-clamp and the second semi-clamp upper end and retract head, described in retract head be arc
Shape, tight latch mechanism is positioned at the first semi-clamp and the second semi-clamp angle position, in order to fixing or regulation the first semi-clamp and the
Angle angle between two semi-clamps, it is characterised in that: also including crank pin and conduction stick, two retract head by two
Individual crank pin respectively with the first semi-clamp and the second half clipper joints, conduction stick is to be perpendicular to retract head shapes place plane
Angle be fixedly connected on and retract an outer rim, described conduction stick has several, is evenly distributed retracting an outer rim.
Preferably, position, described conduction stick termination spherically shape.
Preferably, described some conduction sticks spacing each is not more than 0.5cm.
Preferably, described conduction stick a diameter of 0.3～0.5cm.
The connection retracted between head and semi-clamp is changed into passing through crank pin by the present invention by the fixing connection of prior art
Hinged, so that retract head can realize upper and lower pivot angle, and then retractor is easier to different angles enter
Row is fixing；The present invention plays and draws retracting the body fluid that edge can be oozed out by the conduction stick that outer rim adds simultaneously
Lead effect, thus avoid body fluid along retracting the extravasation that head is too much with wound contact position.
In optimal technical scheme: limiting the upper and lower termination of conduction stick as sphere is in order to avoid termination is the sharpest
The secondary injury that wound is caused；Limit the distance between conduction stick unsuitable excessive partly in order to ensure not
There is blind area, drainage relatively abundant, can effectively ensure that the wound being stretched is the most rounded, to wound simultaneously
The injury of mouth is less；Limit conduction stick diameter in the range of 0.3～0.5cm, allow for the drain of this diameter range
Rod be unlikely to the sharpest, simultaneously drainage more abundant.
The present invention achieves prominent technique effect by relatively simple technological improvement, and cost is relatively low, be prone to
Realize, there is good industrialization value.
