Description

A expansion treatment device for lumen passageway excision postoperative
Technical Field
The invention relates to the field of medical equipment, in particular to an expansion treatment device used after a lumen channel resection.
Background
Lumenal passageway resection surgery is commonly applied to the resection treatment of lumenal passageway tumors. Taking the esophagus as an example, after a tumor is removed from the esophagus through a circular incision, the upper and lower portions of the esophagus need to be sutured again. However, after suturing the esophagus up and down, a circular adductive scar often forms at the sutured site, resulting in dysphagia for the patient. It is conventional to insert a catheter into the oesophagus of a patient so that a balloon on the catheter corresponds to the location of the annular adductor scar. The balloon is then inflated by the catheter to expand the balloon to achieve a restorative training treatment that expands and improves scar retraction.
The prior art has produced a special recovery training treatment device in which the outer wall of the balloon is coated with scar softener or anesthetic because the scar is too painful to the stretching effect caused by the expansion of the balloon. However, the drug is slowly administered only after the balloon is inflated and contacts with the annular adduction scar, so that the analgesic effect is not significant. And the coating medicine on the air bag is usually fixed by manufacturers, the types (chemotherapy, anesthesia and softener) and the proportion of the medicine which needs to be applied to the position of the annular adduction scar clinically are different due to the difference among patients, and the medicine is inconvenient to be flexibly prepared by doctors according to the actual situation.

Detailed Description
As shown in figure 1, the dilatation treatment device used after the lumenal channel resection of the invention comprises a catheter 7, wherein the lower end of the catheter 7 is sequentially sleeved with an upper layer balloon 8 and a lower layer balloon 9 at intervals from top to bottom. The upper end of the catheter 7 is connected with a control mechanism, the control mechanism is used for controlling the upper layer air bag 8 and the lower layer air bag 9 to be respectively inflated and deflated, so that after the lower end of the catheter 7 is inserted into an operation position in a lumen channel, a medicine pool is formed by the upper layer air bag 8 and the lower layer air bag 9 in an inflated state and the inner wall of the lumen, and the annular inward scar part is pre-and fully dosed by liquid medicine in the medicine pool.
As shown in fig. 3, a liquid medicine hole 10 is provided in the catheter 7 at a position between the upper balloon 8 and the lower balloon 9. As shown in fig. 4, the catheter 7 has a first lumen 11 connected to the upper balloon 8, a second lumen 13 connected to the lower balloon 9, and a third lumen 12 connected to the drug solution port 10. The cross sections of the first lumen 11 and the second lumen 13 are both circular arc-shaped, the cross section of the third lumen 12 is oval, and the third lumen 12 is positioned between the first lumen 11 and the second lumen 13, so that the tube body of the catheter 7 is fully utilized. The first lumen 11, the second lumen 13 and the third lumen 12 are all distributed along the length direction of the catheter 7, and a liquid medicine port 14 connected with the third lumen 12 is arranged at the end part of the catheter 7 opposite to the liquid medicine hole 10. Therefore, the medicine can be injected into the medicine pool through the medicine liquid port 14 sequentially through the third pipe cavity 12 and the medicine liquid hole 10, and the effect of medicine administration to the annular inner scar position is achieved.
The control mechanism comprises a bidirectional air pump 1, a connector of the air pump 1 is connected with one path of a tee joint 2, and the other two paths of the tee joint 2 are respectively connected with a first tube cavity 11 and a second tube cavity 13 through a gas path channel consisting of an electromagnetic valve 3 and a gas pipe 5 (as shown in figure 2). The control mechanism also comprises a control panel 4 and a pressure gauge 6 for detecting the pressure in the upper layer air bag 8 or the lower layer air bag 9, and the air pump 1 and the two electromagnetic valves 3 are both connected to the control panel 4 and controlled by the control panel 4. In the application process, the doctor can preset the pressure of the upper layer air bag 8 and the lower layer air bag 9 according to different patients, and the control panel 4 controls the opening and closing of the electromagnetic valve 3 so as to achieve the air inlet and air exhaust effects of the upper layer air bag 8 and the lower layer air bag 9. The current air pressure can be observed in real time through the pressure gauge 6, and the air pump 1 and the corresponding electromagnetic valve 3 are controlled to stop when the pressure reaches a preset value.
The using process is as follows: firstly, the lower end of a catheter 7 extends into a lumen channel, so that an upper layer air bag 8 and a lower layer air bag 9 are arranged at the upper position and the lower position of an annular internal scar, corresponding electromagnetic valves 3 are opened, an air pump 1 is matched with a second lumen 13 through a corresponding air pipe 5, the lower layer air bag 9 is expanded and swollen, the preset electromagnetic valves 3 and the air pump 1 stop working, and the lower layer air bag 9 opens the lower part of pathology. Then the medicine is injected to the pathological part from the medicine liquid port 14 through the third pipe and the medicine liquid hole 10. At this time, the lower air bag 9 is inflated to ensure that the medicine is prevented from leaking, and the upper air bag 8 is in a contraction state to communicate the medicine tank with the outside so as to maintain the pressure of the injected medicine liquid. When the injection of the liquid medicine is completed, the upper air bag 8 is inflated. The upper layer air bag 8 and the lower layer air bag 9 are simultaneously kept in an inflated state, so that the medicine pool is closed, and the medicine liquid in the medicine pool can fully relax and relieve the pharmacological parts. Finally, the catheter 7 can be pushed to move up and down by a small amplitude, so that the upper layer air bag 8 and the lower layer air bag 9 can perform massage and relaxation training on pharmacological parts under the lubricating action of the liquid medicine. After training is finished, the upper layer air bag 8 and the lower layer air bag 9 are deflated through the corresponding electromagnetic valves 3 and the corresponding air pipes 5, and then the catheter 7 is drawn out.
In the training process, if the medicine in the medicine pool has stimulation or toxic action on the patient, the medicine liquid in the medicine pool can be pumped out through the medicine liquid hole 10 after the medicine liquid plays a role, so the medicine liquid hole 10 in the embodiment is arranged on the catheter 7 at a position close to the lower layer air bag 9, and the medicine liquid is conveniently pumped out. The number of the third lumens 12 in this embodiment is two, and two opposite liquid medicine holes 10 are correspondingly formed in the catheter 7, so that the injection and the extraction of the liquid medicine are realized through different pipelines without mutual interference, and the medical care personnel can flexibly operate the medical care personnel according to actual conditions.
