In order to solve the technical problem, the technical scheme of the utility model is that: parallel flat retractor of many joints of retracting, including bracing piece, regulation pole, first dwang, second dwang, third dwang, plectrum, the regulation pole run through in the bracing piece, first dwang quantity be two, first dwang one end rotate and set up in bracing piece one end, second dwang one end rotate and set up in the first dwang middle-end in right side, the second dwang other end set up in adjusting the pole end, third dwang one end rotate and set up in the first dwang middle-end in left side, the rotation of the third dwang other end set up in adjusting the pole end, the plectrum ring buckle set up in the first dwang other end.

Furthermore, the two ends of the supporting rod are provided with first rotating columns, and the first rotating columns are integrally connected with the supporting rod.

Furthermore, the upper end of the adjusting rod is also provided with a plurality of first fixing holes, and the upper end of the supporting rod is provided with a second fixing hole.

Furthermore, the upper end of the supporting rod is also movably provided with a fixing bolt, and the outer diameter of the fixing bolt is equal to the inner diameter of the first fixing hole and the inner diameter of the second fixing hole.

Further, the plectrum bottom still be equipped with the sand grip, sand grip and plectrum an organic whole link to each other.

Furthermore, one end of the adjusting rod is also provided with a second rotating column, and the second rotating column is integrally connected with the adjusting rod.

Furthermore, the other end of the adjusting rod is also provided with anti-skid stripes.

Compared with the prior art, the parallel-retracting multi-joint flat plate retractor can adjust the range of the operation visual field only by adjusting the position of the support rod on the adjusting rod by medical personnel according to needs when in use, and the phenomena of slipping and dragging soft addresses cannot occur. Only a single person is needed to operate simply and conveniently, thereby greatly improving the operation efficiency and reducing the labor intensity of medical care personnel.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art, that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail.

Examples

As shown in the figure, the parallel-retracting multi-joint flat plate type retractor comprises a supporting rod, an adjusting rod, two first rotating rods, two second rotating rods, a third rotating rod and a shifting piece, wherein the adjusting rod penetrates through the supporting rod, the number of the first rotating rods is two, one end of each first rotating rod is rotatably arranged at one end of the corresponding supporting rod, one end of each second rotating rod is rotatably arranged at the middle end of the corresponding right first rotating rod, the other end of each second rotating rod is arranged at the tail end of the corresponding adjusting rod, one end of each third rotating rod is rotatably arranged at the middle end of the corresponding left first rotating rod, the other end of each third rotating rod is rotatably arranged at the tail end of the corresponding adjusting rod, and the shifting piece. The bracing piece both ends all be provided with first rotation post, first rotation post link to each other with the bracing piece is integrative, regulation pole upper end still be equipped with a plurality of first fixed orificess, bracing piece upper end be equipped with the second fixed orifices, upper end of the support bar still the activity be provided with fixing bolt, the internal diameter size of fixing bolt external diameter and first fixed orifices and second fixed orifices equal, plectrum bottom still be equipped with the sand grip, sand grip and plectrum an organic whole link to each other, regulation pole one end still be equipped with the second and rotate the post, the second rotate the post and adjust a pole an organic whole and link to each other, the regulation pole other end still be equipped with anti-skidding stripe.

When using, medical personnel are earlier according to actual conditions, place two plectrums in the patient incision, then the regulation pole is held to one hand, another hand promotes the bracing piece, because first dwang, the second dwang, third dwang and bracing piece are connected for rotating between two liang, so when promoting the bracing piece forward, can drive first dwang, rotation takes place for second dwang and third dwang, so can promote the plectrum and remove to open to both sides, thereby can lead out joint operation position, make things convenient for medical personnel to perform the operation, after opening the position that medical personnel needed, twist first fixed orifices and second fixed orifices with fixing bolt in, because first fixed orifices is the through-hole, the second fixed orifices is the screw hole, screw thread and fixing bolt intermeshing in the second fixed orifices, so can fix the bracing piece and the cooperation position of adjusting the pole. The anti-slip stripes can prevent the sliding off when the adjusting rod is held by hand, and the raised lines at the lower end of the shifting sheet can prevent the sliding off of soft tissues.
