Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, clear, develop simultaneously implementation referring to the drawings The utility model is further described in example.

As shown in Figs. 1-5, the utility model discloses a kind of two leaf esophagus dilators of mediastinum pull hook comprising for strutting Two pieces of esophagus strut blade 1, blade seat 2, outer tube 3, Tiebar structure 4, handle 5 and the knob structure that control is strutted for blade 6；The blade 1 that struts is mounted on blade seat 2, and the blade seat 2 is mounted on the tail end of outer tube 3, and connects with Tiebar structure 4 It connects；It is mounted in outer tube 3 and handle 5 built in the Tiebar structure 5；The outer tube 3 is fixedly mounted on handle 5 by preceding knot set 7 One end, the other end of handle 5 connect with knob structure 6, and the movement of 6 opposite handle of knob structure controls the drawing of Tiebar structure 4 It stretches, realizes that control struts 1 opening and closing of blade.

After adopting the above structure, the utility model is mounted on blade seat by strutting blade for two pieces, and struts blade It is connect with Tiebar structure, and Tiebar structure is built in outer tube, is then connect with the knob structure for being mounted on handle tail end, is passed through Knob structure is rotated, and then controls the flexible of Tiebar structure, to drive the pull rod in Tiebar structure, pull rod passes through pin shaft Drive struts blade, by the movement of pin shaft, realizes the opening and closing for strutting blade, and the work due to strutting blade itself With, so the forced area for strutting blade is bigger compared with existing straight-bar type drag hook, esophagus can be strutted by a larger margin, So that the visual field exposure of operation is better, the safety of surgical procedure is improved, and can realize fine tuning control according to demand What system strutted blade struts degree.

The two leaf esophagus dilator of mediastinum pull hook, wherein the Tiebar structure 4 includes pull rod 41 and connecting screw 42, pull rod 41 is mounted in outer tube 3, and one end of pull rod 41 is connect with the end for strutting blade 1, and the other end of pull rod 41 passes through Connecting screw 42 is fixedly connected with knob structure 6.

After adopting the above structure, the utility model is by the way that one end of pull rod to be connect with the end for strutting blade, and another End is fixedly connected by connecting screw with knob structure, so when needing opening to strut blade, it is only necessary to knob structure is rotated, It can realize and pull pull rod flexible, and due to the effect of connecting screw, when rotation, pull rod does not need knob structure And then it rotates, the distance of pull rod can be pulled according to demand, and then control for strutting blade under the action of knob structure Degree is opened, the visual field that operation needs exposure is adjusted.

The two leaf esophagus dilator of mediastinum pull hook, wherein the knob structure 6 includes nut 61, double threaded screw 62 With rear knot set 63；The nut 61 is fixedly connected by double threaded screw 62 with rear knot set 63.

After adopting the above structure, the nut of the utility model is fixedly connected by double threaded screw with rear knot set, so rotation When nut, it is while ties set after rotating, is realized by the rotation of rear knot set and adjust the flexible of connecting screw, and then adjusted The position of pull rod.

The two leaf esophagus dilator of mediastinum pull hook, wherein knot covers one in 63 after the connecting screw 42 is mounted on End, and connect with pull rod 41.

After adopting the above structure, pull rod and rear knot are covered connection by connecting screw by the utility model, so revolving in nut Knot set rotation after being driven when turning, but due to the effect of connecting screw, so not will drive pull rod rotation.

The two leaf esophagus dilator of mediastinum pull hook, wherein the handle 5 is hollow structure, and both ends are respectively set There is the slot 51 for knot set before installing and rear knot set.

After adopting the above structure, the utility model due to handle be hollow structure, so can will after knot set and connection Screw rod is installed in the handle, and pull rod is inserted into handle, stretches in the handle.

The two leaf esophagus dilator of mediastinum pull hook, wherein the blade seat 2 is clamping piece structure, and struts blade 1 One end is connect by pin shaft with blade seat 2.

The utility model is by being arranged to clamping piece structure for blade seat, so two pieces strut blade and pulled and opened by pull rod When, it can prevent from strutting blade and open outward, can equally be opened to scissors.

The two leaf esophagus dilator of mediastinum pull hook, wherein described one end for strutting blade 1 is provided with and struts blade Axis forms the bar shaped slide opening 11 of angle, and the inclined direction of the bar shaped slide opening 11 of two pieces of supports is opposite.

After adopting the above structure, the bar shaped slide opening for strutting blade setting of the utility model, so pin shaft is mounted on bar shaped In slide opening, and the inclined direction for the bar shaped slide opening for linking with pull rod, and being supported due to two pieces is on the contrary, so pull rod is toward post-tensioning When dynamic, blade can be strutted by two pieces and opened.

The two leaf esophagus dilator of mediastinum pull hook, wherein one end of the pull rod 41 passes through slidiing pin and struts Blade 1 links together, and slidiing pin slides in bar shaped slide opening 11, realizes that control struts the opening and closing of blade.

The two leaf esophagus dilator of mediastinum pull hook, wherein be also equipped with first between knot set 63 and handle 5 after described Gasket 8.

The two leaf esophagus dilator of mediastinum pull hook, wherein also installed between the connecting screw 42 and rear knot set 63 There is the second gasket 9.

Working principle: when needing to strut blade opening, user of service can be passed through by rotary nut, nut Knot set drives connecting screw afterwards, and then drives pull rod toward post-tensioning, and then pull rod drives pin shaft, and pin shaft is in the bar shaped for strutting blade Sliding in slide opening struts blade opening to realize；When needing to strut blade closure, by rotary nut, then Pushing drawing rod moves forward, and then mobile pin shaft moves forward in bar shaped slide opening, and realization struts blade closure.

The utility model is connect by using Tiebar structure with blade construction is strutted, it is possible to be controlled by knob structure Tiebar structure, and then realize that control struts the opening and closing of blade, it is two pieces due to strutting blade, and pacified by blade seat Dress can preferably expose surgical field of view compared to straight-bar type pull hook so forced area is bigger when strutting, and promote operation peace Quan Xing.

It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come It says, it can be modified or changed according to the above description, and all these modifications and variations all should belong to the appended power of the utility model The protection scope that benefit requires.
