Abstract
The utility model discloses a drainage device for thoracic cavities, which comprises an outer casing tube, the tail end of the outer casing tube is provided with a fixed plate of the thoracic cavities, and the head end of the outer casing tube is provided with an oblique cone surface; an inner casing tube is arranged in the outer casing tube, the head of the outer casing tube is provided with an air bag, and the inner and outer casing tubes are not provided with calibrations. The drainage device for thoracic cavities has the advantages of simple structure, convenient use, less tissue damage, and small incision. Besides, the utility model is not easily prolapsed, and is easy to be fixed. In the process of drainage, the inner casing tube is not replaced without intubating a tube again, so the utility model can avoid the blockage of a drainage tube, can control the depth of puncture and drainage to avoid damaging lungs, and reduce complicating diseases.
Description
This utility model belongs to technical field of medical instruments, relates to a kind of thoracic duction instrument.
At present, thoracic duction instrument mainly contains a trocar drainage system and a mushroom rubber tube drainage system.Trocar drainage system mainly is made up of sleeve pipe and puncture needle, puncture needle inserts in the sleeve pipe during use, on skin, scratch a little otch, penetrate thoracic wall with the trocar then, transfer to puncture needle, the silica gel drainage tube that will have side opening inserts the thoracic cavity by sleeve pipe, transfers to sleeve pipe, with suture drainage tube is fixed in thoracic wall.This law otch is less, and tissue injury is few, but drainage tube easily stops up or deviates to cause drain failure and subcutaneous emphysema from thoracic wall; A mushroom rubber tube drain, this method is thick than the pipe that the trocar inserts, and be difficult for stopping up, and head end is umbrella, be difficult for deviating from from the thoracic cavity, but otch is big, and tissue injury is many, and the operating time is long, easily causes thoracic cavity infection.And above-mentioned drainage is difficult to grasp the puncture drainage degree of depth, causes complication.
The purpose of this utility model provides a kind of puncture drainage degree of depth and few thoracic duction instrument of complication more easily grasped, to overcome the deficiencies in the prior art.
For achieving the above object, this utility model thoracic duction instrument, comprise trocar sheath, the trocar sheath tail end has the thoracic wall fixing head, and the trocar sheath head end is a scalene cone, dress inner sleeve in the trocar sheath, the internal diameter size of the external diameter of inner sleeve and trocar sheath is corresponding, and the trocar sheath head is set with air bag, and air bag is communicated with gas tube, the other end of gas tube is communicated with gas cell, and internal and external casing is equipped with scale.
Described inner sleeve tail end is established a ring cap, opens a gap on the shade periphery.
Described thoracic wall fixing head is oval, be arranged with two semicircle through wires holes in the above, after trocar sheath inserts the thoracic cavity, pass through wires hole with meche and can be fixed in thoracic wall, there is a circular port at thoracic wall fixing head center, is communicated with trocar sheath, and inner sleeve inserts in the trocar sheath by this circular port, be provided with a fixation clamp on the periphery of circular port, the gap on the size of fixation clamp and the inner sleeve tail end ring cap is corresponding.
This utility model simple structure, easy to use, the trocar sheath head end is that scalene cone helps puncture, and tissue injury is few, otch is little, grasps the drain degree of depth easily according to the scale on the inside and outside sleeve pipe, avoid damaging lungs, air bag on the trocar sheath and thoracic wall fixing head make sleeve pipe be difficult for deviating from and be easy to fixing inside and outside thoracic wall, and in the drain process, not needing again intubate is replaceable inner sleeve, avoid drainage tube to stop up, reduce complication.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model internal and external casing assembling right view.
1 is this utility model trocar sheath among the figure, trocar sheath 1 head end is a scalene cone, dress inner sleeve 2 in the trocar sheath 1, trocar sheath head suit air bag 3, air bag 3 is communicated with gas tube 4, the other end of gas tube 4 is communicated with gas cell 5, internal and external casing 2, be equipped with scale on 1, inner sleeve 2 tail ends are provided with ring cap 9, open a gap 10 on ring cap 9 peripheries, trocar sheath 1 tail end is provided with thoracic wall fixing head 6, and thoracic wall fixing head 6 is oval, be arranged with two semicircle through wires holes 7 in the above, there is a circular port at thoracic wall fixing head 6 centers, are communicated with trocar sheath 1, and inner sleeve 2 inserts in the trocar sheath 1 by this circular port, establish a fixation clamp 8 on the periphery of circular port, fixation clamp 8 is corresponding along the gap on 9 with the ring cap on inner sleeve 2 tail ends.
When implementing chest drainage, elder generation's standardized little otch on skin, bring trocar sheath 1 usefulness puncture needle into thoracic cavity, after transfering to puncture needle, inner sleeve 2 is sent into the thoracic cavity by trocar sheath 1, and the ring cap 9 that rotates on inner sleeve 2 tail ends makes internal and external casing 2,1 fixing by the fixation clamp on the thoracic wall fixing head 68, deviate from the thoracic cavity for preventing sleeve pipe, with 3 inflations of the air bag on the sleeve pipe 1, in the thoracic cavity, expand and block otch, penetrate fixedly thoracic wall of meche in the through wires hole 7 on thoracic wall fixing head 6.Can change inner sleeve 2 at any time in the drain process, avoid stopping up, not need intubate again, only inner sleeve 2 be transferred to get final product from trocar sheath 1.
