Description
Technical field
The present invention relates to open chest surgery the field of medical instrument technology, specifically a kind of thymoma open chest surgery multi-angle chest
Bone retractor.
Background technique
Thymus gland (thymus) is the important lymphoid organ of body, and function is closely related with immune, is T cell differentiation, hair
It educates, mature place.It can also secrete thymin and hormonal substance, have the organ of endocrine dysfunction.On thoracic cavity
Mediastinum front.Late embryogenesis and nascent, people's thymus gland nearly weigh 10-15 grams, are the periods of weight relative maximum in life.With the age
Increase, thymus gland continues to develop, to about 30-40 grams of puberty.Hereafter thymus gland is gradually degenerated, and lymphocyte is reduced, and adipose tissue increases
It is more, until only 15 grams old.
Thymoma is the disease that thymus gland surrounding occurs that lesion generates, and mostly occurs in the middle-aged and the old, and men and women's morbidity is essentially identical,
Clinical manifestation is cough, pectoralgia, aphetite disorder, expiratory dyspnea, trachyphonia, neck region lump and superior vena cava obstruction syndrome, part
Patient can be asymptomatic, only finds when chest X-ray checks.
Thymoma one answers surgical resection after diagnosing, and no matter benign or malignant thymoma should all be cut off as early as possible, excision
Malignant thymoma can use pathological biopsy and instruct aftertreatment, part excision person's postoperative irradiation can be relieved symptom, extends and suffers from
Person's time-to-live.
Thymoma modus operandi is generally open chest surgery or Minimally Invasive Surgery；In open chest surgery, chest is supportted after lancing
It opens, but has an irregular arc incision, strutted using to sternum retractor, and existing sternum retractor generally comprises
Handle, rack gear, runner, lever arm and fixed arm, the push plate on lever arm and fixed arm are integrated chemical conversion type, do not have polygonal
The adjusting of degree, while baffle itself is also the entirety of long strip type, lacks more perspective adjusting, to cooperate irregular arc to cut
Mouthful, it will cause more damages；Meanwhile lever arm and fixed arm top connect rack gear, are cooperated using rack gear, the unit of adjusting is long
Degree length, cannot finely tune, and lever arm sliding is not smooth, operate relatively elaborate.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved in the present invention is to provide a kind of labour-saving multi-angle tune
The thymoma open chest surgery multi-angle sternum retractor of section.
In order to solve the above technical problems, the present invention provides the following technical scheme that
A kind of thymoma open chest surgery multi-angle sternum retractor, including set connective pole, connecting rod, push plate, rotation connecting plate,
Connection pivot pin, hand twist self-locking screw rod, rotation connection block and double end bearing block, and connection channel bar, institute are equipped in the middle part of the set connective pole

Bar and connecting rod can be welded with rotation connecting plate installation axle on rear side of connection pivot pin rotation, the set connective pole and connecting rod lower end,
The rotation connecting plate installation axle is mounted on rotation connecting plate；The rotation connecting plate is respectively mounted there are three uniformly distributed push plate；The set
Rotation connection block mounting hole is equipped on front side of connective pole and small end, rotation connection block mounting hole upper end, which is mounted on, to be turned
Link block is moved, self-locking nut is welded on the rotation connection block, hand is mounted on inside self-locking nut and twists self-locking screw rod, is performed the operation
The screw tip that hand twists self-locking screw rod is welded with hand lever, and the hand twists and is equipped with double end bearing block between the end of self-locking screw rod.
As the further improvement project of the present invention: the set connective pole includes socket gonnecting rod body, connects channel bar and pin hole,
It is set in the middle part of socket gonnecting rod body there are two channel bar is connected, connects and form link slot between channel bar, be equipped with pin hole in the middle part of connection channel bar.
As the further improvement project of the present invention: the push plate upper end is equipped with connecting shaft, and connecting shaft is internally threaded
Hole is equipped with screw rod card convex inside threaded hole.
As the further improvement project of the present invention: the rotation connecting plate includes rotation connecting plate body, push plate mounting hole and rotation
Turn connecting plate mounting hole, rotates and set on the preceding folded plate of connecting plate body there are three equidistant push plate mounting hole, rotate the perpendicular folded plate of connecting plate body
Rear end is equipped with rotation connecting plate mounting hole.
As the further improvement project of the present invention: the connecting shaft of the push plate is coupled with push plate mounting hole, push plate
Connecting shaft can around push plate mounting hole rotate.
As the further improvement project of the present invention: the rotation connecting plate installation axle and rotation connecting plate mounting hole cooperation are pacified
Dress, rotation connecting plate installation axle can turn around rotation connecting plate mounting hole.
As the further improvement project of the present invention: double end bearing block both ends set that there are two symmetrical threaded hole, spiral shells
Screw is respectively mounted inside pit.
As further improvement project of the invention: push plate is replaced with screw thread rushing board mechanism, the screw thread ledal-pushing machine
Structure is mounted on rotation connecting plate lower end, and the push plate includes screw thread push plate and wing nut, and screw thread push plate upper end is equipped with butterfly spiral shell
It is female.
As further improvement project of the invention: the screw thread push plate includes screw thread push plate body and screw thread push plate screw thread
Bar, screw thread push plate body upper end are welded with screw thread push plate threaded rod.
Compared with prior art, the beneficial effects of the present invention are:
1, push plate of the invention can surround rotation connecting plate installation axle rotation around rotation connecting plate rotation, rotation connecting plate again,
The rotational angle of push plate is improved, the angle that patient opens chest is more bonded, avoids secondary insult；
2, the present invention twists self-locking screw rod, rotation connection block and double end bearing block using hand and cooperates, to adjust distracted length,
Using linear regulation, degree of regulation is high, and can two-way simultaneous adjust, that is, stop it is i.e. self-locking, it is more convenient to use；
3, the present invention also can be used screw thread rushing board mechanism and carry out the angle after secured adjusted, and the screw thread push plate that several are fixed is more
Stick on the wound of conjunction, more convenient locking struts.
For the present invention using simply, stability is good, reduces secondary insult, is worthy to be popularized.
