Abstract

The utility model discloses a thorax trocar, which comprises a bushing and a needle core matched with the bushing; the sections for the bushing and the needle core are all ellipse. The bushing of the thorax trocar in the utility model is flat with ellipse that guarantees the thorax mirror and other surgery apparatus can be inserted into the same thorax surgery hole at the same time. The device can decrease the pain and risk to the patient when adding to open hole in the thorax. Besides, the section of the bushing is ellipse that guarantees the communication performance between the rib gaps; the design also provides the corresponding thorax trocar for the thorax mirror whose sections are similar ellipse with the operational hole.

Description

The thoracoscope trocar

Technical field

This utility model belongs to medical instruments field, relates to a kind of thoracoscope trocar.

Background technology

The cross section of the mirror body of clinical employed thoracoscope is circle at present, and the trocar that the guiding thoracoscope enters pleural space also is the circular casing pin that adapts with it.When undergoing surgery; thoracoscope need enter the thoracic cavity by patient's intercostal space; and the intercostal space is the gap that forms between two parallel ribs of patient; when patient's intercostal space dwindles; usually can influence passing through of the trocar and thoracoscope, cause the patient to have to use the less trocar of diameter and thoracoscope.Owing to do not have handle hole on the less thoracoscope of diameter, therefore when operation, need be on patient's thoracic wall in addition separately perforate place the trocar and introduce operating theater instruments such as biopsy forceps.Like this, not only increase patient's misery, and increased the risk that the thoracic wall perforate brings.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is exactly that a kind of thoracoscope trocar that can reduce the patient suffering, reduce operation risk will be provided.

For achieving the above object, this utility model is a kind of thoracoscope trocar, the nook closing member that comprises sleeve pipe, is complementary with this sleeve pipe, and the cross section of described sleeve pipe and nook closing member is ellipse.

Further, also comprise sleeve cap, the external diameter of sleeve cap and the internal diameter of described telescopic inlet are complementary, and have two through holes on this sleeve cap, and the axis of through hole and described telescopic axis are parallel to each other.

Further, have motion stops on the described sleeve cap, the external diameter of this motion stops and the internal diameter of described through hole are complementary.

Compared with prior art, flat, the ovalize of sleeve pipe of this utility model thoracoscope trocar has guaranteed the trafficability characteristic of the thoracoscope trocar between the intercostal space of large-size, reduces at thoracic wall and increases misery of bringing and the risk that the patient is given in perforate.

The specific embodiment

Among Fig. 1-14, the thoracoscope trocar comprises sleeve pipe 1, nook closing member 2 and sleeve cap 3, and the cross section of sleeve pipe 1 and nook closing member 2 is ellipse, and the outer surface of the inner surface of sleeve pipe 1 and nook closing member 2 mates mutually.Be furnished with active sleeve cap 3 on the inlet 4 of sleeve pipe 1, have two through holes 5 (6) on the upper surface of this sleeve cap 3, motion stops (not shown) and through hole 5 (6) are complementary.Motion stops can utilize rubber or other similar material to make.

During use, in at first packing nook closing member 2 into sleeve pipe 1 from 4 covers that enter the mouth, after sleeve pipe 1 and nook closing member 2 be punctured to pleural space, nook closing member 2 is extracted, on inlet 4, cover sleeve cap 3, introduce circular thoracoscope by one of them through hole 5 on the sleeve cap 3, another through hole 6 usefulness motion stops clog, to guarantee the relative seal of pleural space.When apparatuses such as needs introducing biopsy forceps are operated, then motion stops is opened, introduce operating theater instruments by through hole 6.If do not cover sleeve cap 3 on the sleeve pipe 1, then can use the thoracoscope of cross section as the oval-shaped band handle hole of class.

The characteristics of this thoracoscope trocar are: in same operation on chest wall hole, introduce thoracoscope and other operating theater instruments simultaneously, reduced at thoracic wall and increased perforate and misery and the risk brought to the patient, simultaneously, the cross section of sleeve pipe 1 is oval-shaped design, also guaranteed its trafficability characteristic between the intercostal space, also wanted the thoracoscope trocar that adapts to for the thoracoscope of the oval-shaped band handle hole of class provides for the cross section.

Claims

1. thoracoscope trocar, comprise sleeve pipe, with the nook closing member that this sleeve pipe is complementary, it is characterized in that the cross section of described sleeve pipe and nook closing member is ellipse.

2. according to the described thoracoscope trocar of claim 1, it is characterized in that also comprise sleeve cap, the external diameter of sleeve cap and the internal diameter of described telescopic inlet are complementary, and have two through holes on this sleeve cap, the axis of through hole and described telescopic axis are parallel to each other.

3. according to the described thoracoscope trocar of claim 2, it is characterized in that have motion stops on the described sleeve cap, the external diameter of this motion stops and the internal diameter of described through hole are complementary.
