Abstract
The utility model relates to a pair of vertebral-body parallel-supporting forceps which are a surgical instrument for parallelly supporting vertebral bodies when the operation of anterior approach of cervicothoracic spine is carried out on a patient with scoliosis. The forceps comprise a forceps body consisting of two parallel arms; and a fixed forceps mouth is arranged on the end part of one parallel arm. The forceps are characterized in that an open-type groove is arranged on the end part of the other parallel arm; a sliding forceps mouth capable of sliding along the open-type groove is arranged inside the open-type groove; the sliding forceps mouth is fixed on the parallel arm by a bolt. The forceps can parallelly support an upper vertebral body and a lower vertebral body which have horizontal displacement without being swung up and down in a confined incision, thus facilitating the surgical operation, and the like, and decreasing the difficulty level of the surgery.
Description
Technical field
This utility model relates to the spinal surgery apparatus, particularly a kind of parallel operating theater instruments that struts of vertebral body that is used for when the odd-shaped patient of spinal column 6 lateral bendings is carried out the spinal column anterior approach.
Background technology
The spinal column anterior approach generally needs through the abdominal cavity or operate in the thoracic cavity, after intervertebral disc that pathological changes is arranged or vertebral resection decompression, needs will adjacent upward hypocentrum parallel strutting to carry out bone grafting and fix.Use the parallel pincers that strut of traditional vertebral body to the corrective surgery of no scoliosis the time, vertebral body is parallel to strut operation and has no problem.If but just there was scoliosis originally in the patient, because of certain vertebral body pathological changes takes place again, need preceding road to excise the disease vertebra and carry out bone grafting fixedly the time, because there is horizontal shift in its adjacent hypocentrum of going up, and the parallel jaw that struts pincers of traditional vertebral body is isometric, and jaw can not arrive under the vertebral body of displacement, in the limited operative incision of range of exposure, vertebral body is parallel to strut pincers and can not swing up and down again and adjust operation, so jaw can not the effectively parallel vertebral body that struts displacement, causes operation difficult.
Summary of the invention
The parallel pincers that strut of the vertebral body that provides a kind of jaw to stretch are provided the purpose of this utility model.
This utility model is achieved in that
The parallel pincers that strut of vertebral body, mainly comprise the caliper of forming by two parallel arms, the end of one of them parallel arms is provided with regular jaw, it is characterized in that: the inboard, end of another parallel arms is provided with an open type groove, being mounted with in the open type groove can be along the sliding jaw of open type groove slip, and this sliding jaw is by being bolted on the parallel arms.
After this utility model adopts said structure, when being used for scoliosis patient's preceding road spinal operation, can be when scoliosis patient anterior approach parallel strut horizontal shift on hypocentrum, in limited operative incision, need not swing up and down and strut pincers, just can strut for carrying out level between the vertebral body that has horizontal shift, make things convenient for operation technique, reduce operating difficulty, make things convenient for this type of operation technique.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, Fig. 2 carries out the parallel user mode reference diagram that struts of vertebral body for the spinal column anterior approach that this utility model is used to not have scoliosis, and Fig. 3 carries out the parallel user mode reference diagram that struts of vertebral body for this utility model is used to have the spinal column anterior approach of scoliosis.
In the accompanying drawing, 1 is that parallel arms, 2 is that open type groove, 3 is that sliding jaw, 4 is that regular jaw, 5 is that bolt, 6 is spinal column.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, this utility model is to be converted by the parallel pincers that strut of traditional vertebral body, mainly comprise the caliper that has two parallel arms 1, the end of one of them parallel arms 1 is provided with regular jaw 4, the inboard, end of another parallel arms 1 is provided with a rectangular open type groove 2, be mounted with a sliding jaw 3 that can slide along open type groove 2 front and back in the open type groove 2, the end of sliding jaw 3 is parallel with regular jaw 4, is used for the parallel operation that struts.Described sliding jaw 3 is fixed on the parallel arms 1 by bolt 5, form one scalable and can locate the back fixed telescopic caliper.
As shown in Figure 2, when the odd-shaped patient of no spinal column 6 lateral bendings being carried out anterior approach when strutting vertebral body, can with sliding jaw 3 retractions and to screw bolt 5 fixing, the both sides jaw is isometric, in the limited incision opereating specification, equally strut operation with the parallel pincers that strut of traditional vertebral body.As shown in Figure 3, when to there being the odd-shaped patient of spinal column 6 lateral bendings to carry out anterior approach when strutting vertebral body, sliding jaw 3 can be prolonged and screw bolt 5 and fix, after both sides jaw difference in length is suitable, still can be in the limited incision opereating specification, the same with the parallel pincers that strut of traditional vertebral body, the parallel easily last hypocentrum that has horizontal shift that struts.The end design of sliding jaw 3 has bolt 5 to slide in open type groove 2 and can be tightened, and is fixing and parallel with regular jaw 4 in place to guarantee sliding jaw 3.
Claims (2)
