Abstract
The utility model relates to a closed trocar used for thoracocentesis, which comprises a flexible lower bushing (1), and is characterized in that a connecting thread (9) is arranged at the upper end of the flexible lower bushing (1); a chamber (4) is arranged at the lower end of the flexible lower bushing; a stylet (3) is arranged in the flexible lower bushing (1); a rigid upper bushing (2) is matched with the flexible lower bushing; a rubber plug (6) is arranged at the upper end of the rigid upper bushing (2); a connecting nut (8) is arranged at the lower end of the rigid upper bushing; and a drainage tube is arranged on the side wall of the rigid upper bushing (2). The closed trocar used for thoracocentesis has the advantages of small volume, simple structure, convenient operation, less surgery wound, and light patient suffer. Moreover, the closed trocar used for thoracocentesis can arrange a tube for puncture by one time; tissues and bushings are tightly contacted, which is hard to generate subcutaneous emphysema; moreover, drugs can be fed into a thorax simultaneously through the rubber plug at the end part of the rigid upper bushing.
Description
Technical field
This utility model medical apparatus technical field relates in particular to a kind of thoracentesis enclosed trocar.
Background technology
Traditional closed drainage generally needs to cut skin and subcutaneous tissue, and passivity is separated muscle, enters the thoracic cavity.This mode is put pipe difficulty, so that intubate by force, and patient trauma is heavy, and is painful big, puts pipe back surrounding tissue and contacts imprecision with drainage tube, easily forms subcutaneous emphysema, and can not carry out the thoracic cavity administration simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the thoracentesis of the facilitating operation enclosed trocar.The realization technical solution adopted in the utility model is: this enclosed trocar includes the software setting of casing, the cased upper end of software is provided with connecting thread, the lower end is provided with chamfering, in the software setting of casing nook closing member is set, be mated sleeve pipe on the hardware, telescopic upper end is provided with rubber stopper on the hardware, and the lower end is provided with the attaching nut, and a telescopic side ancient piece of jade, round, flat and with a hole in its centre is provided with drainage tube on the hardware.
This utility model volume is little, and is simple in structure, easy to operate, and operation wound is little, and patient is painful light, and puncture and intubation is once finished, and tissue contacts tightly with sleeve pipe, is difficult for producing subcutaneous emphysema, and can be by the rubber stopper thoracic cavity administration simultaneously of cannula tip on the hardware.
Description of drawings
Fig. 1 is the cased structural representation of software of the present utility model;
Fig. 2 is a telescopic structural representation on the hardware of the present utility model.
Among the figure, 1, the software setting of casing, 2, sleeve pipe on the hardware, 3, nook closing member, 4, chamfering, 5, side opening, 6, rubber stopper, 7, drainage tube, 8, the attaching nut, 9, connecting thread.
The specific embodiment
With reference to accompanying drawing, this enclosed trocar includes software setting of casing 1, the upper end of software setting of casing 1 is provided with connecting thread 9, the lower end is provided with chamfering 4, nook closing member 3 is set in the software setting of casing 1, has been mated sleeve pipe 2 on the hardware, the upper end of sleeve pipe 2 is provided with rubber stopper 6 on the hardware, the lower end is provided with attaching nut 8, and the side ancient piece of jade, round, flat and with a hole in its centre of sleeve pipe 2 is provided with drainage tube 7 on the hardware.
Use this utility model operating process: at first select the site of puncture, routine disinfection, the shop aseptic towel, in the site of puncture local infiltration anesthesia, cut skin, software setting of casing 1 inserted slowly together with nook closing member 3 perpendicular to the thoracic cavity, the sense of breakthrough is arranged after, extract partly nook closing member 3 out, again the software setting of casing is inserted 3～4 centimeters simultaneously, continue to extract nook closing member 3 out, when nook closing member 3 leaves the thoracic cavity, be close to chest with mosquito forceps and clamp software setting of casing 1, extract nook closing member 3 fully out, connect sleeve pipe 2 on the hardware, screw nut 8, drainage tube 7 is connected with drainage bottle by flow sub, unclamp mosquito forceps, at this moment, should have gas or liquid to overflow in the drainage bottle, the skin suture otch, the fixed sleeving art finishes simultaneously.
