Drainage chamber 1 and visual chamber 2 use elastic material, have increased and have looked the holistic deformability of bendable drainage tube, are convenient for crooked in the art, reduce and look the pressure of bendable drainage tube to brain contact position, improve the operation security, also be convenient for be suitable for the endoscope that the specification is different, improve the compatibility of visual bendable drainage tube, be suitable for more use scenes, have certain structural strength simultaneously, can not flattened, lead to devices such as endoscope to damage, the reliability is high. Because the production process is simple and low in cost, the visible bendable drainage tube can be set as a disposable product, the cross infection of patients is avoided, and the cleaning cost after the operation is reduced.
In a preferred embodiment, as shown in FIGS. 1 and 2, the sides of the drainage lumens 1 are provided with drainage holes 7. When the hematoma is not at the bottom of the groove, the bending degree of the visible bendable drainage tube on the side surface of the groove is not enough to make the end part bend and enter the region, the drainage hole 7 on the side surface can be controlled to align to the hematoma position, the drainage device is controlled to drain the hematoma through the drainage hole 7, and the applicability of the device is improved.
In a preferred embodiment, as shown in FIGS. 1 and 2, the visualization lumen 2 and the drainage lumen 1 are arranged in parallel and the lumen walls are connected. Drainage chamber 1 and visual chamber 2 can the integrated into one piece manufacturing, reduces the equipment step in the production, and reduction in production cost does benefit to the batch production who realizes the drainage tube.
In a preferred embodiment, as shown in fig. 1 and 2, the sides of the drainage chamber 1 and/or the visualization chamber 2 are provided with scales 8. The doctor can judge the depth that visual bendable drainage tube introduced the brain recess according to scale 8, and the position is stretched into to the visual bendable drainage tube of control to this control drainage tube male degree of depth and select suitable hematoma drainage mode. Improve the safety of the visible bendable drainage tube and the accuracy of operation, and can obtain information such as bleeding point depth, bleeding amount and the like according to the scale 8 to assist the subsequent treatment of patients. If hematoma happens again at the same position of the brain of the follow-up patient, the doctor can quickly find the hematoma according to the recorded hematoma position in the first operation, the scale 8 and other data, and the operation efficiency is improved.
In a preferred embodiment, as shown in fig. 1 and 2, the closed end of the viewing chamber 2 is spherical, ellipsoidal, bullet-shaped or flat-bottomed.
In a preferred embodiment, as shown in FIGS. 1 and 2, the closed end of the drainage chamber 1 is spherical, ellipsoidal, bullet-shaped, or flat-bottomed.
The doctor can be according to the shape of patient's brain recess, the shape of the shape isoparametric selection suitable drainage chamber 1 blind end, the 2 blind ends in visual chamber to reduce the damage of operation to the brain, can make drainage hole 7 be close to the bleeding point simultaneously, improve the operation quality.
A visually orientable bend-controlling drainage device, as shown in fig. 1 and 2, comprising: the visible bendable drainage tube, the endoscope capable of directionally controlling bending, the display, the drainage tube and the drainage device have the characteristics; wherein: the orientable bending-controlled endoscope is detachably arranged in the visual cavity 2; the display is connected to the orientable bend-controlling endoscope and displays the image shot by the orientable bend-controlling endoscope; the drainage tube is detachably arranged in the drainage cavity 1 and penetrates through the seal head 3; the drainage device is connected to the drainage tube and provides negative pressure for the drainage tube.
During the operation, the doctor can insert the controllable bendable drainage tube into the brain area through the skull, and the doctor can observe the brain condition and the position of the controllable bendable drainage tube through the controllable bendable endoscope, so as to guide the operation. After a doctor finds a bleeding point through the controllable bendable endoscope, the front part of the visible bendable drainage tube is moved to a hematoma part, then the hematoma is directly drained or drained through the drainage hole 7, and the operation is finished after the hematoma is removed and the visible bendable drainage tube is taken out.
The endoscope and the drainage tube are connected to the drainage tube in a detachable mode, so that the endoscope and the drainage tube can be conveniently detached, cleaned or replaced. The doctor is looking for bleeding some in-process, can only insert the endoscope in visual drainage tube of buckling, increases the deformability of visual drainage tube of buckling, reduces the resistance that visual drainage tube of buckling removed in the brain, has reduced the operation degree of difficulty of visual drainage tube of buckling for the operation process and reduce the possibility that visual drainage tube of buckling harms the brain, insert drainage hematoma in the visual drainage tube of buckling with the drainage tube after finding bleeding point again, it is more convenient to operate. The user also can insert the drainage tube in drainage chamber 1 in advance, improves and looks the holistic intensity of bendable drainage tube, avoids inserting the drainage tube in-process, and partial air in the drainage chamber 1 gets into the brain, improves the security of operation.
The display is connected with the controllable bendable endoscope, and a doctor observes the position of the visible bendable drainage tube through the display, so that the problem that the doctor cannot know the position of the drainage tube and the condition of the brain in the prior art is solved, the drainage tube does not need to be used for pulling and inserting the drainage tube at different positions of the brain for many times, and the safety and the accuracy of the operation are greatly improved; meanwhile, the system can reliably prompt a doctor whether the hematoma is completely removed or not, thereby avoiding hidden danger and improving the operation quality. And the doctor can use the controllable bendable endoscope to observe the brain condition near the bleeding point, and if the doctor finds out the conditions of brain lesion caused by hematoma, new bleeding point generated by the extrusion of the nearby brain by the hematoma and the like, the doctor can timely cure the disease. Doctors can also guide the recovery of postoperative patients according to the observed brain conditions, thereby effectively improving the treatment quality.
The display can display the image shot by the controllable bendable endoscope and simultaneously display the information of the heart rhythm, the blood pressure and the like of the patient, thereby facilitating the doctor to observe the condition of the patient in real time. The drainage device can use the low pressure vacuum aspirator pump, and the doctor can progressively improve vacuum negative pressure value to select suitable negative pressure value according to the hematoma, clear away whole hematoma under the prerequisite of not damaging the brain, improved among the prior art doctor and selected the technical problem of negative pressure value without the reference, avoid negative pressure value undersize to cause the problem that the hematoma is remained or negative pressure value too big causes the damage of brain.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
