Abstract
The utility model relates to a surgery instrument, in particular to a vena cava separator used for cardiac surgery minimally invasive surgery. The vena cava separator comprises a handle fixed to the rear end of a supporting rod, and a circular ring is fixed to one side of the front end of the supporting rod and provided with a notch and has elasticity in the radial divergence direction. The face of the circular ring is perpendicular to the supporting rod, the supporting rod is composed of multiple joints, every two joints are connected through a hinged shaft, and the supporting rod can only be bent toward the side of the circular ring in a rotary mode. The notch of the circular ring is in smooth transition, the circular ring is made of medical plastics, and a metal elastic ring is embedded inside the circular ring. The vena cava separator used for the cardiac surgery minimally invasive surgery is simple in structure and practical and can be freely bent and perform internal free separation on the heart and blood vessels very conveniently without excessively damaging other tissues.
Description
Technical field
This utility model relates to a kind of operating theater instruments, particularly a kind of caval vein separator for Cardiac Surgery Minimally Invasive Surgery.
Background technology
At present, in cardiac surgery operation, superior and inferior vena cave to be separated with surrounding tissue after setting up extracorporeal circulation, be convenient to cuff blocking-up, be needed application cavity vein separation pincers.But in Minimally Invasive Surgery, operative incision is little, caval vein position is dark, and the caval vein elastic separating plier length of existing clinical practice is short, and being shaped as of binding clip is straight, and is all fixed pliers head, is difficult for, by free caval vein rear wall abundant, therefore must being improved.
Summary of the invention
This utility model, in order to make up the defect of prior art, provides a kind of easily by the free caval vein rear wall sufficient caval vein separator for Cardiac Surgery Minimally Invasive Surgery.
The present invention is achieved through the following technical solutions: a kind of caval vein separator for Cardiac Surgery Minimally Invasive Surgery, comprise handle, handle is fixed on the rear end of support bar, front end one side of support bar is fixed with its of gap radially disperses direction tool annulus springy, anchor ring and support bar are perpendicular, support bar is made up of more piece, is connected, only with rotoflector in annulus lateral between joint and joint by jointed shaft.
Described annulus gap rounding off, annulus is medical plastic, its inside is embedded with stretch metal ring.
When use, blood vessel that can hand-held this apparatus will separate in vitro slides in annulus by gap, because the design's support bar can only be to curving, when operation annulus slides into patient chest intracavity, can grasp machine with feel or by B, rotary handle, to control the bending direction of support bar, can easily blood vessel be separated with surrounding tissue, and cause very little wound.
The caval vein cyclone separator arrangement of Cardiac Surgery Minimally Invasive Surgery of the present utility model is simple, practical, can free bend and can carry out easily free separation in painstaking effort body, not its hetero-organization of excessive damage.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 looks up annulus end enlarged drawing in Fig. 1.
In figure, 1. support bar, 2. annulus, 3. stretch metal ring, 4. gap, 5. jointed shaft, 6. hinged slip circle, 7. handle.
Detailed description of the invention
A kind of caval vein separator for Cardiac Surgery Minimally Invasive Surgery, comprise handle 7, handle 7 is fixed on the rear end of support bar 1, front end one side of support bar 1 is fixed with its of gap 4 radially disperses direction tool annulus 2 springy, anchor ring and support bar are perpendicular, support bar 1 is made up of more piece, is connected, only with rotoflector in annulus lateral between joint and joint by jointed shaft 5.Described annulus gap 4 rounding ofves, annulus is medical plastic, its inside is embedded with stretch metal ring 3.
