Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Please refer to fig. 1-2, the thoracoscope mediastinum distractor, including main part piece 1, the rectangle opening has been seted up on the main part piece 1, rectangle open-ended inside is provided with two sleeve pipes 3 and a rotatory piece 2, two sleeve pipes 3 set up in the both sides of rotatory piece 2, two perforation 13 that run through the formula are seted up to rectangle open-ended inner wall, the inside of rotatory piece 2 is provided with two movable rods 4 that can remove to one side that deviates from each other, two movable rods 4 remove to one side that deviates from each other respectively and extend to the outside of main part piece 1 through sleeve pipe 3 and perforation 13, one side that the movable rod 4 of both sides deviates from each other is provided with arc fixture block 7.

Further, but inside rectilinear sliding of movable rod 4 sets up the inside at rotatory piece 2, internal thread 12 has been seted up on the sleeve pipe 3 inner wall of both sides respectively, external screw thread 11 has been seted up on the outer wall of movable rod 4, movable rod 4 is in the same place through internal thread 12 threaded connection on external screw thread 11 and the sleeve pipe 3 inner wall, and the screw thread of internal thread 12 on the movable rod 4 of both sides is opposite direction, through rotatory piece 2, can drive movable rod 4 rotatory this moment, cooperation internal thread 12 and external screw thread 11's connection, can drive movable rod 4 and remove or remove to one side that is close to each other to one side that deviates from each other this moment, the completion struts and cancel the action of strutting.

Further, inner wall strip groove 9 has been seted up on the inner wall of rotatory piece 2, integrated into one piece has slip fixture block 10 on the position that movable rod 4 corresponds inner wall strip groove 9, slip fixture block 10 is in the same place with inner wall strip groove 9 activity joint, inner wall strip groove 9 is the rectangular channel, slip fixture block 10 is the rectangular channel, through having set up slip fixture block 10 and inner wall strip groove 9, consequently when drive movable rod 4 removes, movable rod 4 only can follow 2 rotatory while of rotatory piece and carry out rectilinear movement.

Further, arc fixture block 7 is curved piece, jack 5 has been seted up to the one end that movable rod 4 corresponds arc fixture block 7, fixed mounting has inserted bar 6 on arc fixture block 7 corresponds the position of jack 5, inserted bar 6 is pegged graft with jack 5 together, one side fixed mounting that arc fixture block 7 is close to the central point has gasbag 8, through having set up pluggable arc fixture block 7, when this device is not disposable product, can only produce disposable arc fixture block 7 and inserted bar 6, in the time of at every turn using, disinfect the device main part, then open disposable assurance, take out inserted bar 6 and arc fixture block 7, then insert the inside of jack 5 with inserted bar 6 can, such setting has reduced the production of device, and can reuse the major structure of this device simultaneously, lower in the cost, simultaneously movable rod 4 is rotatable when stretching out and drawing back to the outside, because inserted bar 6 is pegged graft in the inside of jack 5, arc fixture block 7 can not follow the rotation.

Further, a week scale has been seted up to the flexible end outer wall face of movable rod 4, and zero label department on the scale corresponds the both sides wall face of main part piece 1, through observing the extended position of scale, can the surveyability know the extension length, and the width of being convenient for more struts as required adjusts.

When using this device, with 7 joints of arc fixture block at the thorax opening part, then slowly rotate rotatory piece 2 with the finger, drive movable rod 4 removes to the one side that deviates from each other, then struts the opening gradually, accomplishes the process of strutting.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
