Abstract
The utility model discloses a thoracoscopy, including a mirror body. The mirror body is provided with an optics visual mirror, an operation hole is further provided. The operation hole is arranged in the mirror body, and the shaft line of the operation hole is parallel with the shaft line of the optics visual mirror; the cross section of the mirror body is an ellipse shape, and the length of the short shaft of the ellipse is smaller than 5mm. The cross section of the utility model is a flat shape, and passes the chest cavity to enter to an ellipse main body of the pleural cavity with the easiness to pass the narrow rib distance. Compared with the round shape chest cavity mirror, the utility model ensures the same sight as well as increases the operation hole, which reduces the hole opening number of the chest wall of the sick to make the operation become more easier to reduce the pain of the sick and the venture of the chest cavity hole opening.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of thoracoscope.
Background technology
Sell in the market and the thoracoscope of clinical practice is cylindrical, enough big in order to guarantee the visual field, the diameter of the thoracoscope of routine is 5～10mm, and the diameter of needle-like thoracoscope is about 3mm.If have handle hole (being the biopsy hole) on the thoracoscope, then the diameter of thoracoscope is all more than 10mm.When carrying out thoracoscopy and treatment clinically, use the thoracoscope of band handle hole not only comparatively convenient, but also can reduce the perforate number on patient's thoracic wall, reduce patient's misery.But, also can often run into the very little patient in intercostal space clinically, in this case, if use the thoracoscope of diameter as the band handle hole more than the 10mm, then can't pass patient's intercostal space and enter pleural space, at this moment, the patient can only select diameter little and not with the thoracoscope of handle hole, and need more in addition on patient's thoracic wall open a hole more, thereby increase the painful of patient and brought unnecessary risk.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is exactly will provide a kind of can pass narrow intercostal space and easy to operate follow-on thoracoscope.
For achieving the above object, this utility model is a kind of thoracoscope, comprises the mirror body, has the optics visor in the mirror body, also comprises handle hole, and this handle hole is arranged in the described mirror body, and the axis of handle hole is parallel with the axis of described optics visor; The cross section of described mirror body is the class ellipse, and this oval minor axis length is less than 5mm.
Further, the ratio between the length of the length of the oval-shaped major axis of class in the cross section of described mirror body and minor axis is 1: 2.
Compared with prior art, the cross sectional shape of this utility model thoracoscope is a flat, its main part of passing that thoracic wall enters pleural space is the class ellipse, passes narrow intercostal space easily, and compares with the circular thoracoscope that passing through property does not similarly have a handle hole, can guarantee the identical visual field, the handle hole of Zeng Jiaing has reduced the number of aperture on patient's thoracic wall again, makes operation process easier, alleviate the patient suffering, reduce the risk that the thoracic wall perforate brings.
Description of drawings
Fig. 1 is the structural representation of this utility model thoracoscope.
The specific embodiment
Among Fig. 1, the cross section 2 of the mirror body 1 of thoracoscope is the class ellipse, and its minor axis is 5mm, and major axis is 10mm.Have eyepiece 3 on the top of mirror body 1, the side of mirror body 1 is provided with light guide bundles interface 4.Optic visual tube 6 is installed in the cavity of mirror body 1, also is provided with handle hole 5 simultaneously, and the axis of the axis of optic visual tube 6 and handle hole 5 is parallel to each other.
During work, because the cross section of the mirror body 1 of thoracoscope is the class elliptical shape, it is the class ellipse that thoracoscope passes the main part that thoracic wall enters pleural space, and the oval-shaped transverse diameter of class is little, passes narrow intercostal space easily.This thoracoscope is compared with the circular thoracoscope that passing through property does not similarly have handle hole, can guarantee the identical visual field, has increased handle hole again, reduced the number of aperture on patient's thoracic wall, make operation process easier, alleviate the patient suffering, reduce the risk that the thoracic wall perforate brings.
In addition, the oval-shaped minor axis of class in the cross section 2 of mirror body 1 can also be made 3mm or 2mm etc. according to actual needs, and the ratio between the length of major axis and the length of minor axis is also done the adjustment of correspondence.
Claims (2)
1. a thoracoscope comprises the mirror body, has the optics visor in the mirror body, it is characterized in that, also comprises handle hole, and this handle hole is arranged in the described mirror body, and the axis of handle hole is parallel with the axis of described optics visor; The cross section of described mirror body is the class ellipse, and this oval minor axis length is less than 5mm.
2. according to the described thoracoscope of claim 1, it is characterized in that the ratio between the length of the oval-shaped major axis of class in the cross section of described mirror body and the length of minor axis is 1: 2.
