Description

Technical area

The present invention relates to a staged expandable dilator with the removable handle. It belongs to the medical device.

Technical background

As the body ages, people are prone to diseases of the lumbar, thoracic and cervical vertebrae. Conventional medication or massage is slow and painful for the patient. Treatment by surgery causes a wound on patients and affects their physical appearance. In addition, wound pain, feeling of fullness or numbness after surgery often occur. The muscle, the blood vessel, and the nerves that are near a surgical wound could be injured. It could take even longer for a patient to recover from the surgery and be healed. In contrast, minimally invasive endoscopic spine surgery (MIEC) causes minor wounds and less pain. A patient can be healed faster. Therefore, this method is always preferred and for a sensitive device is required. Therefore, it is much more important that the surgeon can conveniently and easily control a device. Because the MIEC begins with the creation of the work process. This is done by the gradual expansion or exclusion of soft tissue. With a dilator without a handle, it is difficult to determine the exact surgical site. In contrast, with a handle, a gradual expansion of soft tissue can not be done. This is often an extension device to exchange. Every time the device is replaced, it is reinserted into the affected area. The difficulty of the operation increases accordingly.

The invention has for its object to provide a novel gradual expandable dilator with the removable handle. After excluding the soft tissues, the removable handle can be removed for the time being, the next stage dilator subsequently inserted, and the operation rapidly continued. This is intended to reduce the duration of the operation, to make the exclusion of the soft tissue even more precise, which ultimately can contribute more to the success of the operation.

The technical concept in the present invention: It is a novel gradual expandable dilator with the removable handle, consisting of dilators and a removable handle. The removable handle is located at one end of the dilator. The clamp can be used to clamp the dilator with the removable handle. When necessary in an operation, the removable handle of the 1-stage dilator can simply be removed and the second-stage dilator inserted to dilate the soft tissues. This makes the extension or exclusion of soft tissue even more precise.

The above-described stepwise expandable dilator with a removable handle is characterized by having a conical tip at the other end of the dilator. The conical tip also allows accurate positioning of the next-stage dilator to the center of the first-stage dilator.

The step-expandable dilator with a removable handle described above is characterized by having a scale graduation on the body of the dilator. With the scale graduations, one can easily measure and recognize how deep the dilator is inserted into the soft tissues, by avoiding the injury of the other tissues and can increase the success of the operation.

The above-described stepwise expandable dilator with a detachable handle is characterized in that the outside diameter of the dilator is from 2.0 mm to 2.9 mm, the inside diameter is from 0.6 mm to 1.4 mm.

The step-expandable dilator with a removable handle described above is characterized in that the outer diameter of the dilator is 2.5 mm, the inner diameter is 1.0 mm.

The step-expandable dilator with a detachable handle described above is characterized in that the length of the dilator is from 120 mm to 180 mm.

The step-expandable dilator with a removable handle described above is characterized by the fact that the device has a total of 7-stage dilatators from the inside out, which are gradually expandable to relieve the pain of patients. The outer diameters of the 7-stage dilators are 2.8 mm 3.3 mm, 3.4 mm 3.9 mm, 4.0 mm 4.5 mm, 4.6 mm 5.1 mm, 5.2 mm 5, respectively , 7 mm, 5.8 mm 6.3 mm and 6.4 mm 6.9 mm, the inner diameters are respectively 2.4 mm 2.9 mm, 3.0 mm 3.5 mm, 3.6 mm 4, 1 mm, 4.2 mm 4.7 mm, 4.8 mm 5.3 mm, 5.4 mm 5.9 mm and 6.0 mm 6.5 mm. The inside diameter of a dilator is always 0.2 mm larger than the inside diameter of the next-stage dilator.

The above-described stepwise expandable dilator with the detachable handle is characterized in that the detachable handle has an upper handle button and a lower handle button. The upper handle knob has at one end the threads, the lower handle knob has the thread matching threaded hole. At the end of the thread is the clamping claw. The connection of the upper handle knob with the lower handle knob through the threads allows their installation and removal.

The above-described stepwise expandable dilator with the detachable handle is characterized in that the upper handle knob has a through hole.

The above-described stepwise expandable dilator with the detachable handle is characterized in that the anti-slip pattern in both the upper handle knob and the lower handle knob by a doctor while handling by the anti-slip effect still grip the dilator and can control.
