Abstract
The utility model relates to the technical field of medical equipment, concretely relates to device is cut to valve replacement dedicated line under full thoracoscope. It neither can harm the heart tissue, can accurately in the short time cut unnecessary partial valve stylolite to the optimal length again. The utility model discloses a technical scheme include the scissors body, a shear blade of scissors body be quiet shear blade, another shear blade is for moving the shear blade, the thickness of quiet shear blade be 2mm, be provided with the recess on it, the recess set up in apart from 1 - 2mm on scissors head department of quiet shear blade.
Description
First, technical field：
This utility model is related to technical field of medical instruments, and in particular under a kind of Total thoracoscopy, valve replacement dedicated line is cut
Device.
2nd, background technology：
In conventional intracardiac repair under direct vision valve replacement surgery, Cardiac valve prosthesiss are by valve stitching thread and human heart annulus
Sutured, after firm knotting, cut with ordinary lines and stitching thread redundance is wiped out by root, after such as wiping out, the valve seam for staying
Zygonema is too short, and stitching thread can be caused to take out de-, forms perivalvular leakage, and after such as wiping out, the valve stitching thread for staying is long, can cause card
Lobe, above-mentioned situation can all jeopardize patient vitals.Conventional intracardiac repair under direct vision valve replacement surgery, due to surgical field of view it is good, working place
Greatly, skilled operation technique is added, above-mentioned risk can be made hardly to occur.But under Total thoracoscopy in valve replacement surgery, by
It is to be displayed on fluorescent screen by hysteroscope light source in surgical field of view, fluorescent screen is two dimensional surface, lacks stereoscopic vision, it is difficult to accurate
Positioning, completes accurate operation and has difficulties.Patient is operated by several apertures are beaten on patient's thoracic wall, and working place is little,
The angle for wiping out redundance valve stitching thread is restricted, the heart tissue of easy impair cardiac valve periphery, also easily makes
After wiping out, the valve stitching thread for staying is too short or long, increases the risk of operation.With valve under cardiovascular surgery Total thoracoscopy
The gradually popularization of replacement operation, this risk are consequently increased.
3rd, utility model content：
This utility model is in order to solve the weak point in above-mentioned background technology, there is provided valve replacement under a kind of Total thoracoscopy
Dedicated line cuts device, its both will not impair cardiac tissue, again can at short notice accurately by redundance valve stitching thread cut to
Optimal length.
For achieving the above object, the technical solution adopted in the utility model is：Under a kind of Total thoracoscopy, valve replacement is special
Line cuts device, including shears body, it is characterised in that：One shear blade of described shears body is quiet shear blade, another
Shear blade is dynamic shear blade, and the thickness of described quiet shear blade is 2mm, is provided with groove.
Described groove is arranged at the 1-2mm of scissors bit of quiet shear blade.
Compared with prior art, this utility model has the advantage that as follows with effect：This utility model simple structure, use
It is convenient, while wiping out unnecessary valve stitching thread, protect heartsurroundings from damage, reduce rapidly and efficiently
Operating difficulty, it is extremely advantageous to patient's smooth recovery.
4th, illustrate：
Fig. 1 is structural representation of the present utility model；
A-A sectional views of the Fig. 2 for Fig. 1；
Reference：1- shears bodies, the quiet shear blades of 2-, 3- move shear blade, 4- grooves.
5th, specific embodiment：
Referring to Fig. 1 and Fig. 2：A kind of cardiac valve annulus test device, including shears body 1, described shears body 1
One shear blade is quiet shear blade 2, and to move shear blade 3, the thickness of described quiet shear blade 2 is 2mm to another shear blade, thereon
Fluted 4 are arranged, described groove 4 is arranged at the 1-2mm of scissors bit of quiet shear blade 2.
Using method of the present utility model is：After the completion of under Total thoracoscopy, valve replacement stitching thread knots, by Total thoracoscopy
Lower valve replacement dedicated line cuts the groove 4 of device, and valve stitching thread is blocked outside thoracic wall, uses quiet shears along valve stitching thread
Piece 2 is pushed to valve stitching ring, the scissors bit of quiet shear blade 2 is withstood on valve stitching ring, the dynamic shear blade 3 of shearing, makes valve
Stitching thread is cut up at groove 4, and the valve stitching thread for staying is exactly the distance of 2 scissors bit of groove 4 and quiet shear blade, i.e.,
2mm.In the same manner, all of valve stitching thread is cut successively completes operation technique.
