Abstract
The utility model discloses a rib expands and props device for thoracic surgical operation with adjustable, the bottom of spout middle part is equipped with along spout length direction's the little spout that runs through square pipe, six prismatic pegging graft in the spout, it has cylindrical dwang to peg graft in the little spout, the lower extreme of dwang is fixed at six prismatic upper end middle parts, the upper end of dwang is equipped with the knob, the gasket has been cup jointed on the dwang, the gasket is located the upside of square pipe, the lower terminal surface of knob and the up end of gasket pass through spring coupling, the spring cup joints on the dwang, the outer end of square pipe and extension arm all is equipped with arc and expands the fagging. The rib expands and props device for thoracic surgical operation with adjustable presses down the knob, can adjust the two by the rotatory knob of the left and right sides and expand the distance between the fagging, unclamps the knob, in the knob clamp on spout, prevent that its from producing the back skating phenomenon, but also whole device size is smaller, and is lighter and handier with getting up.
Description
Technical field
This utility model relates to thoracic surgery technical field, is specially a kind of adjustable thoracic surgery rib stretching apparatus.
Background technology
At present in thoracic surgery, it is often necessary to cut skin, subcutaneous tissue, Musclar layer separate rib, and by rib dilator, rib is carried out expanded support and can perform the operation.It is understood that human body width is limited, it is not very convenient that big dilator uses, for the dilator that some are little, major part is by threaded adjusting, although but threaded adjusting is steady slow, patient is just how a dangerous, the adjustment of gear box structure is fast, but build is relatively larger, and does not have anti-slip equipment, for this, we design a kind of anti-back skating and light structure scalable dilator.
Utility model content
The purpose of this utility model is in that to provide a kind of adjustable thoracic surgery rib stretching apparatus, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of adjustable thoracic surgery rib stretching apparatus, including rectangular tube, L-type extension arm it is plugged with in described rectangular tube, the horizontal plate of described extension arm is positioned on the inner chamber bottom surface of rectangular tube, the inner cavity surface of the vertical plate of described extension arm is provided with first gear teeth of the length direction along extension arm, described rectangular tube and first gear teeth to inner cavity surface be provided with and second gear teeth of the first gear teeth same specification, connected by gear between described first gear teeth and second gear teeth, gap is left between lower surface and the inner chamber bottom surface of rectangular tube of described gear, the upper center of described gear is provided with six prisms, the inner chamber upper surface of described rectangular tube is provided with the chute of the length direction along rectangular tube corresponding with six prisms, the degree of depth of described chute is less than the gap width between lower surface and the inner chamber bottom surface of rectangular tube of gear, the center bottom of described chute is provided with the little chute running through rectangular tube along track length direction, described six prisms are plugged in chute, it is plugged with cylindrical pivot bar in described little chute, the lower end of described rotation bar is fixed on the upper center of six prisms, the upper end of described rotation bar is provided with knob, described rotation bar is socketed with pad, described pad is positioned at the upside of rectangular tube, the lower surface of described knob and the upper surface of pad are connected by spring, described spring housing is connected on rotation bar, the outer end of described rectangular tube and extension arm is equipped with circular arc expanded support plate.
Preferably, the opening part of described chute is provided with chamfering.
Preferably, the width of described chute is more than the distance between the parallel side of two opposition of six prisms, and the width of chute is less than the Breadth Maximum of six prisms.
Compared with prior art, the beneficial effects of the utility model are: this adjustable thoracic surgery rib stretching apparatus, press lower knob, can regulating the distance between two expanded support plates by left rotation and right rotation knob, unclamp knob, knob is stuck in chute, prevent it from producing back skating phenomenon, and, whole device build is smaller, uses ratio lighter.
