Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in figure 1, the utility model relates to a surgical retractor, which comprises a hook body 1, an outer end joint 2, a metal hose 3, a locking body 4 and a metal wire. The hook body 1 is arranged at one end of the outer end connector 2, and the hook body 1 is used for contacting with a wound and drawing the wound under the action of external force so as to facilitate operation. The other end of the outer end joint 2 is connected with one end of the metal hose 3, and the outer end joint 2 plays a role in connection and fixation. The metal hose 3 is a universal metal hose, that is, a metal hose having a function of being bendable to any position or angle. The metal hose 3 can be a bulb tube tandem type metal hose shown in fig. 2, a ring groove type metal hose shown in fig. 3, or other metal hoses. The other end of the metal hose 3 is connected with the locking body 4, and the drag hook can be integrally fixed on an operating table or a special sliding rail through the locking body 4 without being held by medical staff.

The locking body 4 is provided with a tightness adjusting mechanism 6, two ends of the metal wire are respectively connected with the outer end connector 2 and the tightness adjusting mechanism 6, the tension of the metal wire is adjusted through the tightness adjusting mechanism 6, and when the metal wire is tensioned, the metal hose 3 is pressed by pressure to be kept at a certain position and angle without shaking or changing. For example, when the hook 1 is adjusted to a certain position and angle, the metal hose 3 itself has certain stability and does not change the position and angle unless an external force is applied, but the metal hose 3 may be shaken or may change the position and angle when a small external force is applied. And when operation tractive wound, itself need great pulling force just to make coupler body 1 always with the wound contact and keep the tractive state and not skid, practice shows, if only lean on metal collapsible tube 3 itself to be unable to realize, and the utility model discloses a 6 taut wires of tightness adjustment mechanism, make the wire be in the tensioning state, because metal collapsible tube 3 is when not receiving external force, the attribute of itself has certain elasticity, when the wire is taut, just can make outer end joint 2 and tightness adjustment mechanism 6 compress tightly metal collapsible tube 3 through the pulling force, make metal collapsible tube 3 locking can not change at a certain position and angle, even if medical personnel promote metal collapsible tube 3 from side this moment, can not cause metal collapsible tube 3 to take place position and angle change yet to guarantee the stability of tractive drag hook wound, satisfied the operation demand.

As shown in fig. 4 to 6, in the present embodiment, the slack adjustment mechanism 6 includes an adjustment lever 60 and an adjustment nut 61, the adjustment lever 60 includes a connection portion 601 and a threaded portion 602, the connection portion 601 connects the wires, and the adjustment nut 61 is screwed to the threaded portion 602. The two ends of the metal wire can be fixedly connected with the connecting part 601 and the outer end connector 2 by welding, screw pressing and other fixing connection modes, so long as the metal wire can be fixedly connected, and in order to achieve the best effect, the two ends of the metal wire are connected with the central parts of the connecting part 601 and the outer end connector 2 along the axis.

A mounting hole 41 coaxial with the metal hose 3 is formed through the locking body 4, and one end of the metal hose 3, corresponding to the mounting hole 41, is fixedly connected with the locking body 4; a limit connecting sleeve 42 is arranged at the other end of the mounting hole 41, and the adjusting pull rod 60 is accommodated in the limit connecting sleeve 42.

The outer end of the threaded portion 602 protrudes outwards relative to the end of the limiting connection sleeve 42, and the inner end of the adjusting nut 61 is in limiting and abutting fit with the end of the limiting connection sleeve 42.

When the wire tensioning device is used, the tensioning force of the metal wire can be adjusted by rotating the adjusting nut 61. For example, when the metal wire needs to be tensioned, the adjusting nut 61 is rotated to cause the adjusting pull rod 60 to move outwards to the side away from the limiting connection sleeve 42, so that the metal wire is tensioned, the outer end connector 2 and the tightness adjusting mechanism 6 are forced to press the metal hose 3, and the hook body 1 is locked and positioned. Otherwise, the locking and positioning of the hook body 1 can be released.

Be equipped with on connecting portion 601 and prevent changeing spacing plane 603, correspond on the inner wall of spacing adapter sleeve 42 and prevent changeing spacing plane 603 and be equipped with and prevent changeing spacing arch, mutually support in order to prevent that adjustment pull rod 60 and adjusting nut 61 synchronous revolution from taking place, the condition of avoiding unable realization taut wire.

The hook body 1 is detachably connected with the outer end connector 2, and the hook body 1 is connected with the outer end connector 2 through the quick change connector 5, so that the hook body 1 with different sizes and models can be applicable and quickly replaced. The quick-change connector can adopt common ball and limiting groove structures, and the specific structure is not described any more.

The utility model relates to a drag hook for operation can realize the angle and the position at the nimble adjustment coupler body of a plurality of angles to the mountable is fixed on operating table or special slide rail, has saved medical personnel's physical power.
