Abstract
The invention discloses a pair of reset forceps for healing a massa lateralis atlantis fracture. The reset forceps comprise two forceps arms. The front ends of the forceps arms are bent oppositely, the contour shapes of the front end surfaces of the forceps arms are matched with the shape of the outer side edge of massa lateralis atlantis, and forceps teeth are arranged in the front end surfaces of the forceps arms. In posterior atlantoaxial fusion and before implanting bolts, the front ends of the two forceps arms are used for resetting the separation of the massa lateralis atlantis fracture. A check mechanism between handle parts at the rear of the two forceps arms are used for fixing the expansion angle of the forceps arms in a current position at any time. The end surface shapes of the front ends of the two forceps arms are matched with the shape of the outer side edge of the massa lateralis atlantis, and the forceps teeth are arranged in the front end surfaces of the two forceps arms, thereby stably clamping the separation part of the massa lateralis atlantis fracture. The thicknesses of the front ends of the two forceps arms are more than the thicknesses of the rest parts of the forceps arms, thereby enlarging the contact surface between the front end surfaces of the forceps arms and the massa lateralis atlantis. The reset forceps can be used for realizing the real-time reset of the separation part of the massa lateralis atlantis fracture in an operation and preventing the risk of further separation and displacement of the broken end of the fracture when an internal fixing system is implanted, thus being beneficial to the healing of the fracture end.
Description
Technical field:
The present invention relates to the mankind life article field, relate in particular to medical apparatus and instruments, particularly be used for the temporary fixed system of the atlas burst lateral mass reduction of the fracture, concrete is a kind of reduction forceps that is used for the lateral mass of atlas fracture.
Background technology:
The atlas damage accounts for 2～13% of cervical spine injury, 1.3% of all spinal injuries.Typical atlas bursting fracture has two fracture lines respectively at the forward and backward bow of atlas, demonstrates four fracture presentations, atypical bursting fracture maybe be also with the fracture of lateral mass of atlas.The atlas bursting fracture is if with the transverse ligament damage, promptly be referred to as unstability atlas bursting fracture, in case take place, the mechanical stability of articulatio atlantoepistrophica will receive serious destruction, and the atlantoaxial dislocation that brings thus is serious threat to patient's life.Although non-operative treatment can make the part patient obtain to cure, there is viewpoint to think that non-operative treatment can not make articulatio atlantoepistrophica obtain effective mechanical stability, Atlantoaxial long-term shakiness, entail dangers to patient life.So row way of escape extensive region dentata fusion was a kind of certain efficacious therapy method after articulatio atlantoepistrophica resetted.
In the prior art, the mode of way of escape extensive region dentata fusion mainly contains: (1) way of escape is through articulatio atlantoepistrophica screw technique for fixing, and this technology has good anti-turning effort, but anti-bend and stretch do relatively poor, and can't the fixed structure plant bone mass.(2) way of escape extensive region dentata LOCATION OF PEDICLE SCREW FIXATION technology, when through the articulatio atlantoepistrophica screw is fixing can't successful implementation the time, this technology can be used as the substitute technology of the way of escape through the joint screw fixation technology.Because the atlas bursting fracture exists serious lateral mass to separate laterally more, the risk of lateral mass shift separation when in its operative process, all existing internal fixation to insert in case occur, then possibly brought internal fixation failure and postoperative fracture healing difficulty.Therefore, many through lateral mass displacement problem in the following method solution art in operation technique: (1), selection are than the entry point in the outside, to avoid atlas fracture of the vertebral arch end; (2), have 5 ° leaning angle with ailhead and insert screw, so that the horizontal pressurization lateral mass far-end displacement fracture that resets; (3), screw can select long size, is advisable to reach the lateral mass of atlas frontal cortex, be more conducive to vertically lift recover displacement fracture and extensive region dentata anterior dislocation.But even through above method, postoperative is followed up a case by regular visits to and is still existed fracture to separate the case that causes disunion.
Summary of the invention:
The object of the present invention is to provide a kind of reduction forceps that is used for the lateral mass of atlas fracture, the described this reduction forceps that is used for the lateral mass of atlas fracture will solve the lateral mass that resets in the prior art atlas fracture operation and be shifted, causes postoperative to be difficult for the technical problem of healing easily.
This reduction forceps that is used for the lateral mass of atlas fracture of the present invention; Comprise two tong arms; Described two tong arms intersect the back through the bearing pin connection at the middle part, the rear portion of any tong arm has included handle portion, wherein; The front end of described two tong arms is crooked in opposite directions, is respectively arranged with inner sunken face in the front end end face of two tong arms.
Further, the contour shape of the front end end face of two tong arms matches with lateral mass of atlas lateral border shape.
Further, be provided with the pincers tooth of two above numbers in the front end end face of two tong arms separately.
Further, in the front end end face of any tong arm, the shape of the line that the summit of described pincers tooth constitutes matches with lateral mass of atlas lateral border shape.
Further, any pincers tooth is all along the thickness direction setting of tong arm front end.
Further, the front portion of any tong arm all includes a root and a forearm separately, and in the front portion of any tong arm, described root is connected through the sagittal articulation structure with described forearm.
Further, described root is connected through a bolt with described forearm.
Further; Be provided with stopping mechanism between the handle portion at two tong arm rear portions; Described stopping mechanism comprises the fixed strip and the ratchet that have continuous lobe, and described ratchet is arranged on the handle portion through a bearing pin, and this handle portion is provided with spring; Described fixed strip is fixedly connected on another handle portion, and described spring is biased in ratchet between any two the continuous lobes on the fixed strip.
Further, the thickness of the front end of two tong arms is all greater than the thickness of remainder in the tong arm.
Operation principle of the present invention is: in the dentata fusion of way of escape extensive region, before inserting screw, the front end that utilizes two tong arms separates the lateral mass fracture and resets.Stopping mechanism between the handle portion at two tong arm rear portions is fixed on current location at any time with the opening angle of tong arm.The end surface shape of two tong arm front ends matches with lateral mass of atlas lateral border shape, and is provided with the pincers tooth in the end face of two tong arm front ends, but stable holding lateral mass fracture separating part.The thickness of the front end of two tong arms has increased the contact surface of tong arm front end end face and lateral mass of atlas all greater than the thickness of remainder in the tong arm.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention has realized that lateral mass of atlas is fractured and has resetted immediately in the isolating art, smooth surface, and incisura is little; Simple in structure; Easy to use, have favorable compatibility with way of escape C1-2 fixed system of the prior art, can be in the dentata fusion of way of escape extensive region, before screw inserts; Separation well resets to the lateral mass fracture; Prevented that effectively internal fixation system from causing the risk of the further shift separation of fracture site when inserting, and helped fracture end healing, for the treatment of unstability atlas bursting fracture provides a kind of effective reduction of the fracture technology.
