Novel surgical retractor

Technical Field

The utility model belongs to the technical field of the operation drag hook, a operation drag hook for thyroid surgery is specifically disclosed.

Background

In the open excision of thyroid gland, need carry out the tractive expansion to the operation incision with the drag hook, use more drag hook still ordinary U-shaped drag hook at present, though this kind of drag hook simple structure, convenient to use often need two people to assist when carrying out the tractive simultaneously to two upper and lower directions of notched to go on, this just leads to needing to occupy limited operation region, based on this problem, the inventor has designed a neotype operation drag hook.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel surgical retractor to solve the ordinary retractor that uses at present and need two people to cooperate the completion simultaneously and lead to its problem that needs occupy limited operation area.

In order to achieve the above object, the basic scheme of the utility model is: the utility model provides a novel surgical retractor, including first tractive pole, the second tractive pole of mutual articulated, first tractive pole and second tractive pole axisymmetric arrangement, it all includes the handle, the slope pole, the straight-bar, straight-bar one end is articulated on the first tractive pole has first hook portion, the rotation plane of first hook portion and the plane mutually perpendicular who comprises first tractive pole, the second tractive pole, straight-bar one end is articulated on the second tractive pole has second hook portion, the rotation plane of second hook portion and the plane mutually perpendicular who comprises first tractive pole, the second tractive pole.

The working principle of the basic scheme is as follows:

the angle of the straight rod end of the first traction rod and the second traction rod can be adjusted and controlled through the matching of the handle ends of the first traction rod and the second traction rod; the first draw hook part and the second draw hook part can draw and expand an operation incision of the thyroid gland open type resection, and in the process of drawing and expanding the operation incision, the first draw rod and the second draw rod are rotated to rotate along a hinge point, so that the angle between a plane formed by the first draw hook part and the second draw hook part and a plane formed by the first draw rod and the second draw rod is adjusted.

The beneficial effect of this basic scheme lies in:

(1) Through articulating first hook portion, second hook portion respectively on first pull rod, second pull rod, can realize drawing expansion to two directions of operation incision by single one-hand operation, can adjust the angle between the plane that comprises first hook portion, second hook portion and the plane that comprises first pull rod, second pull rod simultaneously to furthest's improvement operation field of vision and operating space.

Further, the first draw hook part comprises a first extension rod hinged to one end of the straight rod on the first draw rod, and a first draw hook is arranged at the lower part of the first extension rod; the second draw hook part comprises a second extension rod hinged to one end of the straight rod on the second draw rod, and a second draw hook is arranged at the lower part of the second extension rod; the first drag hook and the second drag hook are arranged in an axial symmetry mode. This arrangement provides a basis for a detachable connection between the two components.

Furthermore, first drag hook upper portion can be dismantled with first extension rod lower part and be connected, and second drag hook upper portion can be dismantled with second extension rod lower part and be connected. The first drag hook and the second drag hook can be set to be of various types and structures, and the first drag hook and the second drag hook are convenient to replace.

And the fixing device can fix an angle formed by one end of a handle on the first traction rod and one end of a handle on the second traction rod.

Further, fixing device is including rotating the first sleeve pipe of connecting handle one end upper portion on first traction rod, still including rotating the second sleeve pipe of connecting handle one end upper portion on the second traction rod, and the cover is equipped with the hand and twists the screw rod in the second sleeve pipe, and the screw rod can be realized threaded connection with first sleeve pipe to the hand. The structure is simple, and the stability is high.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a first traction rod 1, a second traction rod 2, a handle 11, an inclined rod 12, a straight rod 13, a first hook part 3, a first extension rod 31, a first drag hook 32, a second hook part 4, a second extension rod 41, a second drag hook 42, a first sleeve 5, a second sleeve 6 and a hand-screwed screw 7.

Embodiment is as shown in fig. 1 and fig. 2, a novel surgical retractor comprises a first traction rod 1 and a second traction rod 2 which are hinged to each other, the first traction rod 1 and the second traction rod 2 are arranged in an axisymmetric manner and respectively comprise a handle 11, an inclined rod 12 and a straight rod 13, one end of the straight rod 13 on the first traction rod 1 is hinged to a first hook portion 3, the rotation plane of the first hook portion 3 is perpendicular to the plane formed by the first traction rod 1 and the second traction rod 2, one end of the straight rod 13 on the second traction rod 2 is hinged to a second hook portion 4, and the rotation plane of the second hook portion 4 is perpendicular to the plane formed by the first traction rod 1 and the second traction rod 2.

The first hook part 3 in this embodiment comprises a first extension rod 31 hinged to one end of the straight rod 13 on the first traction rod 1, and a first drag hook 32 is inserted into the lower part of the first extension rod 31 in an interference connection manner; the second draw hook part 4 comprises a second extension rod 41 hinged to one end of the straight rod 13 on the second draw rod 2, and a second draw hook 42 is inserted into the lower part of the second extension rod 41 in an interference connection mode.

The first draw hook 32 and the second draw hook 42 are arranged in an axisymmetric manner, and meanwhile, the first draw hook 32 and the second draw hook 42 can be set to be in various types and structures so as to adapt to more use scenes.

In addition, the device also comprises a fixing device arranged on the first traction rod 1 and the second traction rod 2, and the fixing device can fix the angle formed by one end of the handle 11 on the first traction rod 1 and one end of the handle 11 on the second traction rod 2.
