Abstract

The utility model relates to a thoracentesis trocar which has the following innovation points: a sleeve and a drainage pipe are arranged, an automatic sealing ring is arranged on the orifice at the tail end of the sleeve; an inner core capable of drawing is inserted in the sleeve, and the top end of the inner core has a tip structure; and an air bag is arranged at the top end of the drainage pipe and is communicated with a thin pipe tightly attaching to the drainage pipe. The utility model has the following advantages: when being used for puncturing, the thoracentesis trocar penetrates into the chest to complete the arrangement of the sleeve by utilizing the tip structure of the inner core, after the sleeve is arranged, the inner core is pulled out, the drainage pipe extends into the sleeve, then the sleeve is pulled out, the air bag is supported by the thin pipe, the sleeve is pulled out, the support air bag blocks a cut, thus preventing the chest from being communicated with outer part. The inner core is pulled out and inserted into a gap of the drainage pipe, the automatic sealing ring recovers under the elastic action of a rubber sheet, and the orifice is sealed, thus ensuring the sealing property. A positioning ring is arranged in the middle of the inner core, so that the tip structure of the inner core just extends out of the top end of the sleeve when the positioning ring props against the orifice at the tail end of the sleeve.

Description

A kind of trocar for chest work

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of trocar for chest work.

Background technology

The thoracic drainage and thoracentesis art is one of diagnosis commonly used such as thoracic trauma and treatment means, and the purpose of thoracentesis is the pressure of pneumothorax in the clear and definite thoracic cavity, the character of hydrops etc., and suction can alleviate compressing to lungs, impel atelectasis.Play therapeutical effect simultaneously.Traditional thoracic drainage and thoracentesis is to adopt scalpel at the skin upper cut under local anesthesia, disposes drainage tube in chest incision and enters in the thoracic cavity, and need sutured.Its shortcoming is: otch is bigger, need strut intercostal muscle by mosquito forceps when inserting sleeve pipe, and needs sutured, and patient is relatively more painful, the process complexity.

The utility model content

The technical problems to be solved in the utility model provides the little trocar for chest work of a kind of wound that punctures.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of trocar for chest work, and its innovative point is: comprise sleeve pipe, described telescopic terminal mouth of pipe place is provided with from dynamic seal ring; Be inserted with the inner core that can extract out in the described sleeve pipe, the top of this inner core is a cutting-edge structure; Also comprise a drainage tube, the top of this drainage tube is provided with air bag, and the tubule that air bag and is close to drainage tube is communicated with.

Further, describedly constitute from the sheet rubber of dynamic seal ring by some indentions, described sheet rubber is evenly distributed on tube ends mouth of pipe inwall and seals up the mouth of pipe.

Further, be provided with locating ring in the middle part of the described inner core.

Advantage of the present utility model is: during puncture, utilize the cutting-edge structure of inner core to penetrate the thoracic cavity and finish telescopic placement, after sleeve pipe is placed, extract inner core out, stretch into drainage tube in the sleeve pipe after, extract sleeve pipe, strut air bag through the tubule gas injection, extract sleeve pipe, the air bag that struts is blocked otch, can prevent thoracic cavity and external communications.Insert in the gap of drainage tube extracting inner core, under elastic reaction, restore, seal up the mouth of pipe, guarantee sealing property from the sheet rubber of dynamic seal ring.Inner core middle part is provided with locating ring, makes that the cutting-edge structure of inner core just stretched out cannula tip when locating ring propped up the telescopic terminal mouth of pipe.

Description of drawings

Fig. 1 is that the sleeve pipe and the inner core of this utility model trocar for chest work inserts the thoracic cavity state diagram;

Fig. 2 is this utility model middle sleeve side view;

Fig. 3 is that the drainage tube of this utility model trocar for chest work inserts the thoracic cavity state diagram by sleeve pipe.

The specific embodiment

As shown in Figure 1, 2, comprise sleeve pipe 1, sheet rubber 2, inner core 3, drainage tube 4, air bag 5, tubule 6.

The terminal mouth of pipe of above-mentioned sleeve pipe 1 is provided with from dynamic seal ring, should constitute from the sheet rubber 2 of dynamic seal ring by some indentions, and each sheet rubber 2 is evenly distributed on sleeve pipe 1 terminal mouth of pipe inwall and constitutes a circle that seals up the mouth of pipe, as shown in Figure 2.This sheet rubber 2 is strutted when the body of rod is arranged in pipe, holds the body of rod and passes through smoothly, and in the pipe during the no body of rod, then restore under elastic reaction, seals up the mouth of pipe.

Be inserted with the inner core that can extract out 3 in the sleeve pipe 1, the top of this inner core 3 is a cutting-edge structure, and locating ring 31 is established at the middle part of inner core 3, and when locating ring 31 propped up the terminal mouth of pipe end face of sleeve pipe 1, the cutting-edge structure of inner core 3 just stretched out the top of sleeve pipe 1.

The top of drainage tube 4 is provided with air bag 5, and this air bag 5 connects by the tubule 6 of being close to drainage tube 4 tube walls, and the other end of tubule 6 connects non-return charging connector 7.

During puncture, utilize the cutting-edge structure of inner core 3 to penetrate the placement that sleeve pipe 1 is finished in the thoracic cavity, after sleeve pipe 1 is placed, extract inner core 3 out, this moment, the sheet rubber 2 from dynamic seal ring restored under the unisexuality effect, sealed up the mouth of pipe, guaranteed sealing property.After stretching into drainage tube 4 in the sleeve pipe 1, extract sleeve pipe 1, utilize trachea to strut air bag 5, extract sleeve pipe 1, the air bag 5 that struts is blocked otch, can prevent thoracic cavity and external communications.

Claims

1. trocar for chest work, it is characterized in that: comprise sleeve pipe, described telescopic terminal mouth of pipe place is provided with from dynamic seal ring; Be inserted with the inner core that can extract out in the described sleeve pipe, the top of this inner core is a cutting-edge structure; Also comprise a drainage tube, the top of this drainage tube is provided with air bag, and the tubule that air bag and is close to drainage tube is communicated with.
