Description

Drainage tube after single-hole thoracoscopy

Technical Field

The utility model relates to the technical field of thoracic surgery, in particular to a drainage tube after single-hole thoracoscopy.

Background

The single-hole thoracoscopic operation is a new technology developed in the recent 10 years of minimally invasive lung cancer treatment, is widely applied at present, and is usually selected to be a single-hole thoracoscopic incision positioned between the 5 th rib, and the special position is selected to better ensure the development of the single-hole thoracoscopic operation technology, but means that a conventional drainage tube is used at the same time, so that the most distal drainage is not ideal. 2 intrathoracic drain tubes are needed to be placed in the postoperative routine, and the intrathoracic drain tubes are placed in the intrathoracic drain tubes from the second intercostal space and the 7 th intercostal space or the 8 th intercostal space respectively, so that the operation flow, the operation cost and the operation time are increased, and the operation is inconvenient for the postoperative patient to move due to the 2 drainage tubes and the drainage bottles. Meanwhile, the inner wall of the conventional drainage tube is smooth, and the flange is arranged on the inner wall of the drainage tube along the conduction path between the drainage inner tube and the drainage outer tube, so that the drainage is not smooth due to the folding of the drainage tube.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The drainage tube after the single-hole thoracoscopy shown in fig. 1 and 2 comprises a drainage tube 1, wherein the drainage tube 1 is formed by integrally connecting a drainage inner tube 2 and a drainage outer tube 3, the drainage inner tube 2 is connected to the upper end and the lower end of one side of the drainage outer tube 3, the drainage outer tube 3 is communicated with the drainage inner tube 2 connected with the corresponding end, the drainage inner tubes 2 at the upper end and the lower end are not mutually conducted, an ear-shaped bending 21 is arranged at the end part of the drainage inner tube 2 at the upper end, a prismatic bending 22 is arranged at the end part of the drainage inner tube 2 at the lower end, and a drainage hole 23 is arranged at the ear-shaped bending 21 and the prismatic bending 22 at the end part of the drainage inner tube 2.

Preferably, the drainage tube 1 is made of degradable elastic silica gel.

Further, a flange is provided on the inner wall of the drainage tube 1 along the conduction path between the drainage inner tube 2 and the drainage outer tube 3.

Further, a screw is provided at the end of the drainage outer tube 3 of the drainage tube 1.

The utility model relates to a drainage tube after single-hole thoracoscopy, when in use,

1. the sterile package is removed and sufficient skin sutures are placed near the front end of the port to ultimately secure the catheter.

2. The drainage tube is placed from the endoscopic hole.

3. The drainage tube 1 is clamped with a pair of pliers at the position of the end drainage hole 23 on the drainage inner tube 2 under thoracoscopy, and the end position is sent to the paravertebral canal under thoracoscopy. After this time, the limb may be released by opening the ring clamp and allowed to become parallel to the vertebral body.

4. The correct position of the tip is checked, and the two ends of the drainage tube are respectively fixed at the rib diaphragm angles at the top and the bottom of the thoracic cavity by using the lug-shaped bending 21 and the prismatic bending 22 of the outer wall of the tip.

5. The external terminal end of the drainage outer tube 3 is screwed down with the aid of a suture and connected to a water seal system or suction inlet.

The drainage inner tube 2 of the drainage tube 1 is designed with a special terminal prismatic outer wall design, has a certain fixing function, and the whole tube is slightly similar to a triangle structure, has a certain stability, and can avoid chest tube displacement, pleural effusion infection and sub-pulmonary tension. The tail end of the drainage inner tube 2 is placed in, so that the air and liquid from the tip of the lung to the pleural cavity of the far-end lung can be effectively discharged, and the drainage tube 1 can be conveniently and smoothly pulled out after drainage is finished.

The whole drainage tube 1 is made of novel degradable large-elasticity silica gel materials, and meanwhile, the design of a Y-shaped structure can ensure that the tube is pulled out without broken tubes. At present, two drainage tubes are conventionally used, namely, the double-cavity drainage tube is lowered to a single tube, so that materials are saved.

For patients, the drainage hole (the drainage tube is arranged in the operation cavity mirror hole) is not arranged after the operation, and when the drainage tube 1 is pulled out, half of pain is reduced compared with the conventional method, so that the rapid rehabilitation is facilitated. For doctors, the time for placing the drainage tube 1 in the operation can be reduced, the anesthetic dosage can be properly lightened to a certain extent, and the working efficiency is improved. The whole drainage tube 1 inner wall is designed with a flange, and the flange can ensure that the drainage tube 1 is not completely blocked in a folded state, can still ensure smooth circulation of liquid and gas, ensures the safety of postoperative drainage, and has practicability.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
