Abstract
The invention discloses a wire retractor for endoscopic thyroidectomy, which is applicable to surgical field exposure of the endoscopic thyroidectomy. The wire retractor comprises a supporting body, wherein muscle fixing heads are arranged at two ends of the supporting body; the supporting body is an elastic supporting bar, two ends of the elastic supporting bar are connected with the muscle fixing heads by virtue of spherical hinges; and notch tanks for fixing muscle are formed in the muscle fixing heads, and the notches of the notch tanks are formed toward two ends. According to the wire retractor, an approximate semispherical surgical operating space is established by smartly utilizing the muscle group restoring force for separating the anterior cervical muscle group, rather than establishing a manual inflation surgical field, wherein the elastic supporting bar is divided into a long section and a short section by a hinge column, and two parts of the elastic supporting bar are folded at the hinging column in the using process to generate a larger operating space, so that the actual operation becomes practical. The wire retractor is simple and practical in structure, closely combines the characteristics of endoscopic thyroidectomy, and can acquire space and surgical field necessary to a surgery by revolutionarily using mechanical support instead of manual support.

The present invention adopts following technical scheme to realize: cavity mirror thyroid operation retractor, comprises that two ends are provided with the supporter of muscle fixing head 1; Described supporter is the elastic support bars 2 of strip, and described elastic support bars 2 two ends connect described muscle fixing head 1 by ball pivot 21; Described muscle fixing head 1 is provided with the gap slot 11 for fixing muscle, and the breach of described gap slot 11 is towards the arranged outside of fixing head.
Further, described elastic support bars 2 is by hinge post 23 two joints that are divided into that one is long and the other is short, its short-and-medium joint is for regulating extension 24, the main body that a long joint is resiliency supported, strutting after the muscle of both sides, visual area, can regulate extension by stirring, ensure the effect of drag hook separating muscle simultaneously, the position of adjustable elastic support bar within the specific limits, more being conducive to operating doctor in operation independently adjusts, and in use, form elasticity opisthotonos at hinge post place, realize larger operation technique space and visual area.
Preferably, described muscle fixing head 1 is square shape, centered by described gap slot 11, axle is perpendicular to the breach cylinder groove in fixing head front and back sides, described breach along the axial setting of described cylinder groove and outside muscle fixing head the wherein side of end face, the edge of breach cylinder groove is round and smooth, can not cause the secondary damage of muscle.
Concrete, the bulb of described ball pivot 21 is arranged on elastic support bars 2 two ends, wherein ball-and-socket is arranged in described muscle fixing head 1, the internal volume of described ball-and-socket is greater than 1/2 bulb, bulb can not be deviate from from ball-and-socket, bulb has the complete rotary freedom of a direction with respect to ball-and-socket, and has the incomplete rotary freedom of two other vertical direction, there is no other axial freedoms.
Further, the connecting portion 22 that described elastic support bars 2 two ends bendings are provided with U-shaped is connected with ball pivot 21, can further improve the strain of elastic support bars, and the elastic force that available buffer elastic support bars distortion produces acts on muscle, causes secondary injury.
Preferably, described supporter be two arranged in a crossed manner, after it struts muscle, below supporter, form a hemispheric operation technique space, can respectively the skin of operating field both sides and muscle be separated, adopt surgery tractor of the present invention arranged in a crossed manner, use more conveniently, and can obtain larger visual area scope.
Preferably, the engineering plastics of the entire elastic metallic material of described resiliency supported strip adoption or entire high-intensity high-tenacity are made.
From the above mentioned, exquisite composition of the present invention, simple in structure, easy to use, with low cost, can automatically the muscle of the wild both sides of endoscopic thyroidectomy and skin be separated, without assistant's operation drag hook is set in addition, and visual area scope is wide, drag hook position can suitably be adjusted, can not cause the secondary damage of patient's muscle, can, in wide clinical application, can give the universal of device for endoscopic thyroid surgery and promote and bring huge change.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
