Abstract
The utility model provides a pair of orthopaedic steel wire guide forceps, which comprise two symmetrical forceps bodies, wherein the middle parts of the two forceps bodies are connected through a rotating shaft; two jaw openings and two forceps handles arranged on the front side and the rear side of the rotating shaft respectively, wherein the two jaw openings are oppositely jointed to form an approximately-round or approximately-oval structure; hollow tubes arranged at the front part of the two jaw openings, wherein steel wire ports are arranged at the end of the hollow tubes in the position close to the rotating shaft, the diameters of the hollow tubes of the two jaw openings are different, and the outside diameter of either hollow tube is matched with the inside diameter of the other hollow tube, thereby allowing the insertion of the end part; inclined planes formed at the end part of the jaw openings, wherein the cutting edges formed by the inclined planes and the outer walls of the hollow tubes are positioned on the inner side of the approximately-round or approximately-oval structure; and two limiting clamps arranged on the inner side of the two forceps handles in the position close to the hand-holding rings and matched to each other. The guide forceps don't cause the tissue injury, facilitates the steel wire to pass through, ensures that the surgical incision is small, can be automatically fixed to release one hand of the surgeon, and is easy to be generalized and applied.
Description
One, technical field
This utility model relates to a kind of medical apparatus and instruments of bone surgery, particularly relates to a kind of orthopaedics steel wire guiding pincers.
Two, background technology
Long bone fracture is the commonly encountered diseases of orthopaedics, and along with the development of communication and building industry, it is also more and more that the damage of the high-energy of wound causes comminuted fracture.
When carrying out long bone comminuted fracture open reduction internal fixation, use auxiliary the tying up of steel wire often and pulverize bone piece (sheet) clinically, perhaps when bone grafting, tie up the strip bone grafting.Operating difficulties around steel wire the time, and be damaged to fracture nerve, blood vessel and soft tissue on every side easily, destroy the blood fortune of sclerite (sheet), influence union of fracture.Often need prick the sclerite of splitting with wire rings in the reduction of the fracture in the operation, require on the biomechanics to protect the complete of periosteum and fracture surrounding soft tissue as far as possible, the blood supply with the protection skeleton helps union of fracture.Because fracture end has tough and tensile fascia and muscle to adhere to, traditional tinsel technique for fixing is by peeling off the method that muscle adheres to place and periosteum, the fracture end that wire rings is walked around splitting encircles to be pricked fixingly, and this operation be the risk that nonunion was peeled off greatly, increased to cost, tissue to sacrifice sclerite (piece) blood fortune.
A kind of orthopaedics wire introducer is disclosed in the Chinese patent 200420068827.3, the technical scheme of this patent is such: the nigger that has the steel wire inlet connects the short handle that has the steel wire outlet by rotating shaft, nigger is the slope shape articulation port with short handle contact position, the too close jaw place of design steel wire inlet of this patent, and the direction of its slope mouth has problem, not near inboard,, and be difficult for smooth guiding steel wire at the time easy embedding folder tissue that uses.
Three, summary of the invention
The objective of the invention is above-mentionedly to determine that propose a kind of orthopaedics steel wire guiding pincers, this guiding clamps protects fracture and bone piece (sheet) surrounding tissue to greatest extent in order to overcome; it is convenient to wear steel wire; surgical injury is little, and can fix automatically, hands of liberation surgical staff.
Content of the present invention is: a kind of orthopaedics steel wire guiding pincers, contain the two parts symmetrical caliper, and two caliper middle parts are connected by rotating shaft, and both sides are respectively jaw and pincers handle before and after the rotating shaft, and described two jaws butt joint back forms sub-circular or approximate ellipsoidal; The front portion of described two jaws is hollow pipe, is provided with steel wire port at this hollow pipe near the rotating shaft end, the hollow pipe thickness difference of described two jaws, and one of them hollow pipe external diameter and another hollow pipe internal diameter are complementary, and the end can be inserted; Described jaw end is the inclined plane, and the cutting edge that this inclined plane and hollow pipe outer wall form is positioned at described circle or oval-shaped inboard.
The inboard near hand-held ring place of described two pincers handles is provided with two spacing buckles of coupling.
Described two spacing buckles are straight plate shape, respectively with two pincers handle near normal.
Described two spacing buckles are circular shape, and the center of circle of circular arc is in rotating shaft.
Described steel wire port is positioned at the planar side of jaw, or is positioned at the outer back side of jaw.
Beneficial effect of the present invention
1, wound is little
Described jaw end is the inclined plane, the cutting edge that this inclined plane and hollow pipe outer wall form is positioned at described circle or oval-shaped inboard, is difficult for injuring surrounding tissue and blood confession when using in operation, and is difficult for embedding folder tissue, steel wire enters extra heavy pipe from tubule and goes out, and is convenient to operation; Described in addition steel wire port is positioned at hollow pipe near the rotating shaft end, does not more need too big otch when carrying out Minimally Invasive Surgery, just can use this steel wire guiding pincers.
2, can fix a hands of liberation surgical staff automatically
The inboard near hand-held ring place of described two pincers handles is provided with two spacing buckles of coupling, can clamp together a mouthful back in this steel wire guiding and lock, hold mode, this moment, surgical staff did not just need with hand-held firmly this pincers handle, thereby can make surgical staff be more convenient for operating, improve the quality of operation.
