A kind of novel traction device suitable for ankle arthroscopy operation

Technical field

The present invention relates to medical technical fields, and in particular to a kind of novel traction device suitable for ankle arthroscopy operation.

Background technique

Ankle arthroscopy operation is a Minimally Invasive Surgery, is mainly used for treating ankle-joint osteoarthritis, Impingement Syndrome, astragalus The diseases such as osteocartilaginous and subchondralo bone injury, fracture of ankle joint and ligament injuries of ankle joint have many advantages, such as that at low cost, wound is small and rehabilitation is fast. When carrying out ankle arthroscopy operation, in order to obtain instrumentation under good surgical field of view and mirror, need conventional remote using lower limb End limbs pulling equipment maintains the requirement of the abundant stretching of ankle-joint, and the Lower Distal Extremities limbs traction equipment price of profession compared with It is high.The simple and easy method that the court's ankle arthroscopy operation at present is drawn using unarmed traction or calcaneum Kirschner wire, but this hair Bright inventor has found that this method tractive force is not easy to maintain, joint expansion is insufficient, cannot sufficiently expose ankle-joint The visual field, especially back visibibility, while special messenger's continuous traction is needed, thus expend a large amount of manpowers.

Summary of the invention

It is drawn when for the operation of existing ankle arthroscopy using unarmed traction or calcaneum Kirschner wire, there are tractive force not It easily maintains, joint expansion is insufficient, cannot sufficiently expose the ankle-joint visual field, especially back visibibility, while special messenger being needed to continue Traction, thus the technical issues of consuming a large amount of manpowers, the present invention provides a kind of novel traction dress suitable for ankle arthroscopy operation It sets.

In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:

A kind of novel traction device suitable for ankle arthroscopy operation, including installing and adjusting mechanism, support and are led at fixed link Draw regulating mechanism, the installing and adjusting mechanism includes can be with the installation pillar of the existing connecting column rotation socket of operating bed, the peace Fill pillar be equipped with spliced eye, it is described installation pillar top be equipped with and spliced eye vertically through adjustment threaded hole, the tune Whole threaded hole internal screw thread is connected with vertical adjustment bar；The support fixed link includes support stock and support quarter butt, the support Fixation is supported in the bottom end for the vertical adjustment bar that one end of stock is plugged in spliced eye and connect with adjustment threaded hole internal screw thread, institute Stating support quarter butt includes thick support rod and ramuscule strut, the fixed company of the other end of one end and support stock of the thick support rod Connect, the other end of the thick support rod is fixedly connected with ramuscule strut, the rotation of the other end of the ramuscule strut be equipped with can with it is thin Support rod body keeps homoaxial anti-drop block；The traction adjustment mechanism includes link block, cylindrical body, regulating wheel and threaded rod, The link block, which is socketed on ramuscule strut and is hindered by anti-drop block, to be taken off, and the link block is equipped with through-hole, the cylindrical body One end is rotatably arranged in through-hole, and the other end of the cylindrical body is fixedly connected on the end face of regulating wheel, the cylindrical body and Regulating wheel coaxial arrangement and axial line are equipped with threaded hole, and the threaded rod is threaded in threaded hole and the both ends of threaded rod It is pierced by threaded hole, one end of the threaded rod is connected with the trussed shore that outer diameter is greater than threaded rod, and the trussed shore is equipped with traction Portion.

Compared with prior art, the novel traction device provided by the invention suitable for ankle arthroscopy operation is before use, elder generation The existing leash system that the bottom end for installing pillar is socketed on the existing connecting column of operating bed, and will be used to draw connection lower limb Knot is on tractive unit；In use, adjusting traction angle by socket direction of the rotational installation pillar on connecting column, adjust simultaneously The length of section support stock one end grafting in spliced eye is far and near to adjust traction, and rotation regulating wheel pass through it is solid with regulating wheel Surely the cylindrical body connected locating rotation in link block through-hole drives the threaded rod being threadedly coupled with cylindrical body and regulating wheel in axis It moves up, and then realizes that the leash traction force request of threaded rod one end tying is adjusted, i.e., correspondence realizes traction angle, leads Adjusting while drawing far and near and traction force request, it is thus possible to reach good traction effect.Therefore, the application does not need special messenger Continuous traction, tractive force are easy to maintain, and joint can sufficiently be expanded, and the ankle-joint visual field can be sufficiently exposed, and reduce operation wound, economical Practical and clinical application degree is high.

Further, the bottom end of the installation pillar, which is equipped with, is adapted to the axial blind hole that column sleeve connects, and the installation pillar Lower rotational be equipped with and be suitable for supporting the adjusting knob of connecting column.

Further, the top of the vertical adjustment bar is interspersed with the horizontal adjustment bar vertical with adjustment bar vertically.

Further, the spliced eye is chamfered edge circular hole, and the surface of the support stock has cuts with what chamfered edge circular hole cooperated Side plane.

Further, the other end of one end of the thick support rod and support stock is integrally formed and is mutually perpendicular to.
