Description
Technical field
The present invention relates to technical field of medical equipment, more particularly, to a kind of novel thorax closed drainage trochar.
Background technology
Closed drainage of thoracic cavity operation is one of most common emergency treatment technique of chest Severe acute disease, because it efficiently solves chest
Physiology of respiration caused by damage is disorderly, has the meaning of milestone in the development of thoracic surgery.The technology treats hand as one kind
Section is applied to hemothorax, pneumothorax, the drainage of pyothorax and Thorax operration, and the treatment for disease plays a very important role.Especially
For tension haemopneumothorax patient, fast and effectively closed drainage of thoracic cavity operation is the key for saving its life.But traditional chest
Complicated, internal organs in easy damaged thoracic cavity during chamber closed drainage and the closed drainage of thoracic cavity operation of various improvement at present puncture,
It is inconvenient to carry, and is not easy to implement before institute, in first aid in hospital, it is more difficult to meet the needs of the rescue and treatment of the wounded in wartime or disaster.
The content of the invention
In order to overcome the problems referred above, the present invention adopts the following technical scheme that：
A kind of novel thorax closed drainage trochar, including telescopic protection head and drainage casing tube, the telescopic protection head
Front end is equipped with bulb, and stretches out taper Pipe Cutting, and taper Pipe Cutting is connected with drainage casing tube, and the rear end of the drainage casing tube is equipped with drainage
Pipe stop part, the rear end of taper Pipe Cutting are equipped with limiting plate, its bottom is connected with spring, and the other end of spring is fixed on drainage casing tube
In the fixed plate of interior design, inclination snap-gauge is fixed with the inner wall of drainage casing tube, snap-gauge front end rear is tilted and is equipped with fixture block, fixture block
It is placed in the inside of telescopic protection head.
The telescopic protection head is solid, and head end is in cylinder.
The outside of the taper Pipe Cutting is equipped with screw thread.
Drainage casing tube and the drainage tube stop part is adopted made of plastic.
Drainage casing tube and the drainage tube stop part is respectively cylindrical and discoid.
It is an advantage of the invention that：It is safe, the complication situation such as lung tissue secondary lesion and bleeding exacerbation does not occur,
It is fast that small, few intercurrent disease, post-operative recovery are damaged to patient, no infection.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the I portions enlarged drawing of the present invention.
Fig. 3 is the vertical schematic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, 3, a kind of novel thorax closed drainage trochar, including telescopic protection first 1 and drainage casing tube
6, the front end of the telescopic protection first 1 is equipped with bulb 2, and stretches out taper Pipe Cutting 3, and taper Pipe Cutting 3 and drainage casing tube 6 connect,
The rear end of the drainage casing tube 6 is equipped with drainage tube stop part 10, and the rear end of taper Pipe Cutting 3 is equipped with limiting plate 4, its bottom and spring
5 connections, the other end of spring 5 are fixed in drainage casing tube 6 in the fixed plate 7 of design, are fixed with and incline on the inner wall of drainage casing tube 6
Oblique snap-gauge 8, tilts 8 front end rear of snap-gauge and is equipped with fixture block 9, fixture block 9 is placed in the inside of telescopic protection first 1.
The telescopic protection first 1 is solid, and head end is in cylinder.
The outside of the taper Pipe Cutting 3 is equipped with screw thread 11.
The drainage casing tube 6 and drainage tube stop part 10 are adopted made of plastic.
The drainage casing tube 6 and drainage tube stop part 10 are respectively cylindrical and discoid.
The course of work is as follows：
When patient needs to carry out closed drainage of pleural cavity, simultaneously routine disinfection drape, after local anaesthesia comes into force, blade cut skin are first positioned
And about 1 cm of subcutaneous tissue, the trochar equipped with drainage casing tube 6 is then vertically arranged in notch, spiral shell is carried out using taper Pipe Cutting 3
Shape is revolved to puncture.At this time, telescopic protection first 1 is because running into the resistance of tissue and in retraction taper Pipe Cutting 3, so that cone of influence shape is not cut
The puncture of pipe 3.And when taper Pipe Cutting 3 is pierced into thoracic cavity, telescopic protection first 1 ejects rapidly because losing the stop of tissue, prevents
Only internal organs are stabbed by taper Pipe Cutting 3 in thoracic cavity, play the role of protecting internal organs.After drainage tube is sent into 2 ~ 3 cm of thoracic cavity at the same time
Puncture tube core is exited, external connecting tube simultaneously connects water-sealed drainage bottle or drainage bag.Finally, intrathoracic drain is fixed on the skin.
When such as one-time puncture is undesirable in piercing process, as long as slowly exiting trochar, the bounce of telescopic protection first 1 is controlled
Amount is, it can be achieved that repeatedly puncture until puncturing successfully.
