Abstract
The utility model belongs to the field of medical instruments, particularly relates to an ankle joint spreader, which comprises a clamp body and two operating ends. Two handles are hinged through a main pin to form the clamp body, and the two operating ends are hinged with the two handles. The ankle joint spreader is characterized in that an adjusting screw is arranged between the two handles, one end of the adjusting screw is hinged with one handle through a hinge lock, an adjusting nut is arranged on one side, extending out of the other handle, of the adjusting screw, anti-slip bends are arranged at the rear ends of the two handles, and the two operating ends are respectively hinged with the two handles through operating-end pins, while the two operating ends are in equidirectional arc structures and anti-slip embossment is arranged on the outer surfaces of the two operating ends. The ankle joint spreader is manly applied to the field of foot and ankle surgeries, particularly ankle surgeries.
Description
Technical field:
This utility model belongs to medical instruments field, and specifically a kind of novel ankle joint dilator is mainly used in the ankle surgical operation, especially the ankle joint field of surgery.
Background technology:
Ankle joint osteochondral fracture, regression and traumatic arthritis are comparatively common, patient's pain is obvious, has a strong impact on walking step state and daily life, often needs to remove free bone, cartilaginous tissue at this type of treatment of diseases, carry out little fractures, even need row ankle joint fusion.Strutted the method for ankle joint such as assistant traction in the past, the Kirschner wire sled is dialled or external fixator retracts etc., assistant's traction method retracts weak effect, the assistant is tired easily; The Kirschner wire sled is dialled method and is slided easily, damage articular cartilage, even damage rear nervus vasculairs structure; And external fixator retracts musical instruments used in a Buddhist or Taoist mass tool complexity, and operating time is long, increases the damage to the patient.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can fully retract ankle joint, is convenient to operation technique in the ankle joint, and the laborsaving ankle joint dilator that saves time safe.
The technical scheme in the invention for solving the technical problem is: a kind of ankle joint dilator, by two handles by the hinged tong-like main body that constitutes of main body bearing pin, and two working ends that are hinged with two handles are formed, it is characterized in that being provided with adjusting screw(rod) between described two handles, one end of this adjusting screw(rod) is hinged by hinged lock and one of them handle, the side that this adjusting screw(rod) stretches out another handle is provided with adjusting nut, described two handle rear ends are provided with anti-skidding elbow, described two working ends are hinged by working end bearing pin and two handles respectively, it is characterized in that two working ends are arcuate structure in the same way, adapt with the arc of trochlea of talus, outer surface is provided with anti-skidding embossing.
This utility model of employing technique scheme compared with prior art, its advantage is: the patient controls the tong-like main body, will can effectively retract the joint behind its working end insertion ankle joint, and the arcuate structure of working end and anti-skidding embossing can be prevented sliding stop, do not damage articular cartilage, the position of the conveniently adjusted handle of pin shaft structure between working end and handle does not influence IA operation technique, and is simple in structure, be convenient to make, handled easily is increased work efficiency, and reduces the unexpected generation of medical treatment.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2
Labelling is as follows among the figure: 1. handle, 2. main body bearing pin, 3. adjusting screw(rod), 4. adjusting nut, 5. anti-skidding elbow, 6. swivel pin, 7. working end, 8. working end bearing pin, 9. anti-skidding embossing.
The specific embodiment:
As shown in drawings, a kind of ankle joint dilator of this utility model, by two handles 1 by the main body bearing pin 2 hinged tong-like main bodys that constitute, and two working ends 7 that are hinged with two handles are formed, it is characterized in that being provided with adjusting screw(rod) 3 between described two handles 1, one end of this adjusting screw(rod) 3 is hinged with one of them handle 1 by hinged lock 6, the side that this adjusting screw(rod) 3 stretches out another handle 1 is provided with adjusting nut 4, described two handle 1 rear ends are provided with anti-skidding elbow 5, described two working ends 7 are hinged by working end bearing pin 8 and two handles 1 respectively, it is characterized in that two working ends 7 are arcuate structure in the same way, adapt with the arc of trochlea of talus, outer surface is provided with anti-skidding embossing 9.
The novel operation principle of this use is: the patient controls the tong-like main structure body that is made of two handles 1, at first rotate the adjusting nut 4 on the adjusting screw(rod) 3, make working end 7 be in closure state, ankle joint is inserted in its working end 7 that has anti-skidding embossing 9, pushing two handles 2 makes working end 7 be flared to the adjusting nut 4 on the rotation adjusting screw(rod) 3 after the desired location, fix two relative positions between the handle 1 and be in fixed open configuration to keep working end 7, when handle 1 influences operation technique, can adjust handle 1 position by working end bearing pin 8.
