Furthermore, the releasable fixing buckle comprises an arc-shaped plate arranged on one side, facing the other spreading arm, of one spreading arm, the spreading arm without the arc-shaped plate is provided with a first through hole for the arc-shaped plate to penetrate through, a clamping sheet is further arranged in the through hole, a pressing handle is arranged on the clamping sheet, the clamping sheet is elastically hinged to the side wall of the through hole, a first rack is arranged on one side, facing the clamping sheet, of the arc-shaped plate, and a second rack matched with the first rack is arranged on one side, facing the arc-shaped plate, of the clamping sheet.
Furthermore, the fastening mechanism comprises a first fastening nut penetrating through the connecting rod and the first adjusting rod, a second fastening nut penetrating through the first adjusting rod and the second adjusting rod, and a third fastening nut penetrating through the second adjusting rod and the third adjusting rod.
Further, the opening rod is arc-shaped.
In conclusion, the utility model has the following beneficial effects: the adjustable expansion device is simple in structure and high in practicability, the device can achieve the effect of changeable expansion shapes by arranging the plurality of adjusting rods and the plurality of fastening mechanisms, the use is convenient, and the variability of the expansion shapes of the device can be stronger by arranging the adjusting rods which are longitudinally hinged and transversely hinged.

Detailed Description
The present invention is described in further detail below with reference to figures 1-3.
Example (b): an incision spreader for oral surgery comprises two hinged spreading assemblies as shown in figures 1 to 3, wherein each spreading assembly comprises a spreading arm 1, a finger hole 2 arranged at one end of the spreading arm 1, a connecting piece 3 arranged at one end of the spreading arm 1 far away from the finger hole 2 and a spreading frame arranged at one end of the connecting piece 3 far away from the spreading arm 1; a releasable fixing buckle is arranged between the two spreading arms 1 and comprises an arc-shaped plate 9 arranged on one side, facing to the other spreading arm 1, of one spreading arm 1, a through hole 10I for the arc-shaped plate 9 to pass through is formed in one spreading arm 1 without the arc-shaped plate 9, a clamping sheet 11 is further arranged in the through hole 10, one end of the clamping sheet 11 is fixedly connected with a pressing handle 12, the clamping sheet 11 is elastically hinged with the side wall of the through hole 10, a rack I13 is arranged on one side, facing to the clamping sheet 11, of the arc-shaped plate 9, and a rack II 14 matched with the rack I13 is arranged on one side, facing to the arc-shaped plate 9, of the clamping sheet 11; the two connecting pieces 3 are both arc-shaped and are hinged with convex surfaces thereof, the unfolding frame comprises a connecting rod 4 connected with the connecting pieces 3, a first adjusting rod 5 longitudinally hinged with the connecting rod 4, a second adjusting rod 6 transversely hinged with the first adjusting rod 5 and a third adjusting rod 7 longitudinally hinged with the second adjusting rod 6, fastening mechanisms are arranged between the connecting rod 4, the first adjusting rod 5, the second adjusting rod 6 and the third adjusting rod 7, and each fastening mechanism comprises a first fastening nut 15 penetrating through the connecting rod 4 and the first adjusting rod 5, a second fastening nut 16 penetrating through the first adjusting rod 5 and the second adjusting rod 6 and a third fastening nut 17 penetrating through the second adjusting rod 6 and the third adjusting rod 7; the one end of adjusting pole three 7 and keeping away from adjusting pole two 6 is installed and is propped open pole 8, props open pole 8 and be arc and smooth surface, is convenient for adapt to the shape of pharynx lateral wall tumour, inserts the clearance of tumour and surrounding tissue.
The working principle is as follows: when the minimally invasive resection is performed on the tumor on the side wall of the oral cavity under the endoscope, after the tumor incision is propped open, the tumor needs to be bent along the tongue root direction at once, the tumor is propped open from the pharynx side along the tongue root direction, then the tumor is bent, the tumor is outlet from the oral cavity along the mouth corner direction along the opposite side oral cavity wall, and then the tumor is bent towards the ear direction on one side outside the mouth corner.
