Problems solved by technology

[0002] During the existing thoracic surgery, the surgical site is mostly located in the upper or lower thoracic cavity, which is easy to damage tissues and organs such as the liver and spleen
Straight tube drainage is used in the drainage of thoracic surgery. For the existing thoracic surgery, the surgical wound is large, and the postoperative pain is severe, which cannot effectively achieve minimally invasive surgery and affects the postoperative recovery of patients.
During the bending process of the straight tube drainage tube, the inner diameter of the tube body will change, and even the lumen will be narrowed, which will affect the drainage effect

Embodiment 1

[0170] like Picture 1-1 , Figure 1-1-1a , Figure 1-1-1b As shown, a minimally invasive chest drainage tube conforming to the anatomical characteristics of the human body, the drainage tube is a gas drainage tube, which includes a tube body 1, and the tube body 1 has an outer section 101, a first bending part 102, and a transition section 103 in sequence , the second bending part 104 and the inner section 105, the outer section 101 and the transition section 103 are bent through the first bending part 102, and the transition section 103 and the inner section 105 are bent through the second bending part 104, At least part of the inner section 105 has a fitting arc section that fits the inner wall of the chest cavity 2 .

[0171] Wherein, a marking line 15 is provided on the tube body 1 for auxiliary positioning when the doctor places the tube. The end of the outer section 101 has a rear nozzle 12 , the front end of the inner section 105 has a front nozzle 11 , and a side ho...

Embodiment 2

[0178] like Figure 1-2 , Figure 1-2-2a As shown, the difference between this embodiment and Embodiment 1 is that the end of the inner section 105 is curled inward to form a curled end, the plane where the curled end is located is the first plane, and the transition section 103 and the fitting arc section The plane where it is located is the second plane, and the first plane intersects with the second plane. The front nozzle 11 and at least two side holes 111 are all provided on the crimped end. Its advantages are: the end of the inner section 105 is curled inward to form a curled end, the plane where the curled end is located is the first plane, the plane where the transition section 103 and the fitting arc section are located is the second plane, and the plane where the first arc is located is the second plane. The plane intersects with the second plane, so that the inner section 105 can coincide with the inner wall of the chest cavity 2, and the curled end can fit closel...

Embodiment 3

[0180] like Figure 1-3 , 1-3-3a As shown, the difference between this embodiment and Embodiment 1 is that a balloon 13 is provided on the inner section 105 of the tubular body 1 near the second bending portion 104, and a balloon 13 is provided at the outer section 101 of the tubular body 1. An inflation piston 142 is provided. One end of the inflation catheter 14 communicates with the balloon 13 through the catheter opening 141 , and the other end communicates with the inflation piston 142 . The inflation piston 142 can inflate the balloon 13 through the inflation catheter 14, and the balloon 13 can contact the inner wall of the chest cavity 2 of the human body and fix the tube body 1 after inflation. After the balloon 13 is inflated and inflated, the inner section 105 of the tubular body 1 can be tightly fixed to the inner wall of the chest cavity.

Abstract

The invention discloses a minimally invasive chest drainage tube and drainage surgery instruments confirming to human body anatomy characteristics. The drainage tube comprises a tube body which is sequentially provided with an outer section, a first bending part, a transition section, a second bending part and an inner section; a section between the outer section and the transition section is bent through the first bending part; a section between the transition section and the inner section is bent through the second bending part; at least a portion of the inner section is provided with an adhering arc section which is adhered to the inner wall of the chest. The minimally invasive chest drainage tube and the drainage surgery instruments confirming to the human body anatomy characteristics have the advantages of achieving minimal invasion of thoracic surgeries, enabling the drainage tube to be confirmed to the human body anatomy characteristics, effectively avoiding luminal stenosis and being good in drainage effect.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a minimally invasive chest drainage tube and a drainage operation device conforming to the anatomical characteristics of a human body. Background technique [0002] In the existing thoracic surgery process, the operation site is mostly located in the upper side chest cavity or the lower side chest cavity, which is easy to damage tissues and organs such as the liver and spleen. Straight tube drainage is used in the drainage of thoracic surgery. For the existing thoracic surgery, the surgical wound is large, and the postoperative pain of the patient is severe, which cannot effectively achieve minimally invasive surgery and affects the postoperative recovery of the patient. During the bending process of the straight tube drainage tube, the inner diameter of the tube body will be changed, and even the lumen will be narrowed, which will affect the drainage effect.
