Between be open, rib cage is strutted with rib spreader, with facilitate doctor observe and operation.Thoracoscopic operation is main in thoracic surgery
Contraindication be the fine and close adhesion extensively of full thoracic cavity, it is therefore desirable to distracted space is larger, thus just have it is various strut it is forcipate
Device for spreading.
Cardiothoracic surgery thoracic cavity struts the middle tool used and has the following problems in the prior art：
1, distracted space is smaller, it has not been convenient to which doctor carries out observation understanding to the case where patient's thoracic cavity, and needs
It is artificially fixed, influences the process of operation；
2, because the inside adhesion structure in people thoracic cavity is different, thus stiction force is also different, so causing during strutting
The bad grasp of rhythm, be easy to cause the secondary injury of patient, totally unfavorable to the recovery of patient.
Utility model content
The purpose of this utility model is to provide a kind of cardiothoracic surgery thoracic cavity device for spreading, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, cardiothoracic surgery thoracic cavity provided by the utility model device for spreading, including lead screw, adjusting block,
First struts arm, second struts arm and arc distraction plate, is threadedly coupled between the lead screw and adjusting block, on the outside of the adjusting block
It is provided with adjusting bracket, connection is socketed between the adjusting bracket and lead screw, the outside both ends of the adjusting bracket are fixedly installed first
Axis pin base, described first, which struts arm and second, struts one end of arm and is rotatablely connected respectively with the first axis pin base, and described first struts
Arm includes two connecting rods, is rotatablely connected by shaft between the connecting rod, described second, which struts arm and first, struts arm
Structure setting is identical, and the bottom end of the lead screw is fixedly installed the second axis pin base, and described first, which struts arm and second, struts arm
The other end of connecting rod be rotatablely connected by the second axis pin base, described first strut arm and second struts arm the other end distinguish
It is fixedly attached to arc distraction plate, the outside of the arc distraction plate is fixed close to the position of bottom end is pasted with silicagel pad.
Further, the top of the lead screw is threaded with Anti-slip cover.
Further, it is fixedly installed connecting plate between second axis pin base, the bottom end of the lead screw is fixed at
On connecting plate, second axis pin base is provided at both ends with groove.
Further, the outside of second axis pin base is fixedly installed handheld board respectively.
Further, twice of length of the length of the lead screw not less than connecting rod.
Compared with prior art, the utility model has the beneficial effects that：
1, it struts arm by strutting arm and second by first and is attached by two axis pin bases, and adjusting block can be passed through
Height on lead screw reaches the control that size is strutted to thoracic cavity, so that the size during thoracic cavity struts can carry out
Intuitively judge and control, observes and understand convenient for doctor, conducive to being normally carried out for operation.
2, by first strut arm and second strut arm subtended angle size come to the size of arc distraction plate subtended angle carry out
Control, and screw thread control avoids slipping, and is also avoided that use in the process due to the difference of people thoracic cavity stiction force size and to suffering from
Secondary injury caused by person, it is simple and practical, convenient for promoting.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, cardiothoracic surgery thoracic cavity provided by the utility model device for spreading, including lead screw 1, adjusting block
2, it first struts arm 5, second strut arm 6 and arc distraction plate 10.
It is threadedly coupled between the lead screw 1 and adjusting block 2, the outside of the adjusting block 2 is provided with adjusting bracket 3, the tune
It saves to be socketed between frame 3 and lead screw 1 and connect, the outside both ends of the adjusting bracket 3 are fixedly installed the first axis pin base 4, and described first
