Description
Technical Field
The utility model relates to the technical field of surgical instruments, especially, relate to a backbone endoscope side direction sleeve pipe is with hollow coaxial dive formula handle.
Background
Hyperostosis is more frequent than middle-aged. It is generally believed that the disease is caused by physical weakness and degeneration after middle-aged; when standing or walking for a long time and holding a certain posture for a long time, the muscles are pulled or torn off, bleeding and hematoma are organized to form spinous or labial hyperosteogeny, which is also called as bony spur or hard osteophyte. Prolapse of intervertebral disc, spinal canal stenosis, hyperplastic osteophyte, and nerve root adhesion are often combined in Asian population. The spinal endoscopic technique treatment becomes an important operation path for spinal diseases, and the spinal combined minimally invasive treatment has wide prospect. When performing spinal endoscopic procedures, it is often necessary to adjust the position and angle of the bony passageways during the procedure.
In order to protect nerves during the process of introducing surgical instruments into the patient, it is necessary to ensure that the nerves are within the visual field of the endoscope. However, the nerve is compressed by the nucleus pulposus or the nerve itself is mutated due to the pathological changes, so that the nerve is deviated from the original position, and the nerve cannot be seen in the endoscope. Therefore, reaming is required, namely: the bony passage is modified so that the angle of the endoscope can be adjusted to find the nerve.
In the prior art, an electric drill is generally used for correcting the bony access, namely: the hard osteophytes are ground off by 1-2 mm. Since the outer wall of the tool, endoscope, or the like used in the surgical operation is cylindrical, it is necessary to modify the passage into a circular arc shape. The electric drill can only correct the passage into a plurality of discontinuous circular arcs and cannot correct the passage into a section of continuous and relatively regular circular arcs, so that the angle of the surgical instrument cannot be adjusted, and the nerve is difficult to find through the endoscope. In addition, the use of an electric drill to modify the bony access is highly susceptible to over-modification, thereby damaging the internal bony tissue.
In order to solve the above problem, another patent of the applicant has devised a manually controlled lateral casing drill and, for ease of handling, a handle is provided at one end of the lateral casing drill.

Detailed Description
The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of this application, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit its scope.
The utility model discloses a hollow coaxial submerged handle for a side sleeve of a spinal endoscope, which is shown in figures 1-2. The handle comprises a holding part 1 and a handle main body 2, wherein the handle main body 2 is provided with a channel for a lateral sleeve to enter, and the side wall of the handle main body is provided with an opening 3 for the lateral sleeve to enter the channel. The channels comprise an inclined channel 4 and a central channel 5 which are coaxially arranged, and the inclined channel 4 and the central channel 5 are sequentially arranged in a spiral structure; the central channel 5 is C-shaped in cross-section.
At least one of the central passage 5 and the lateral sleeves is provided with a fixing portion for fixing the lateral sleeve and the handle. The structure of the lateral sleeves is shown in fig. 3.
When the handle is implemented, the lateral sleeve enters the inclined channel 4 through the opening 3 on the side wall of the handle body, rotates for a certain angle and then enters the central channel 5, and the lateral sleeve and the handle are fixed through the fixing part.
Compared with the prior art, the hollow coaxial submersible handle for the lateral sleeve of the spinal endoscope provided by the embodiment can increase the moment and the moment arm, reduce the labor intensity for correcting the bony passage, increase the reaming speed, shorten the operation time and increase the operation safety.
Specifically, the present embodiment is achieved by designing the handle as a plurality of channels, namely: the central channel and the inclined channel are sequentially arranged in a spiral structure, so that on one hand, the lateral sleeve can be ensured to smoothly enter the channel of the handle, and on the other hand, the lateral sleeve is not easy to slide out of the channel of the handle, thereby providing stable power for correcting the bone passage; on the other hand, the lateral sleeve drill centrifugation in the process of correcting the bony access is effectively prevented, the formation of taper reaming is avoided, the damage to other tissues around the part needing to be corrected is reduced, and the pain of a patient is relieved.
It should be noted that, by arranging the fixing part, on one hand, the lateral sleeve is not easy to slide in the process of correcting the bony access, thereby ensuring that the lateral sleeve can effectively expand the hole, shortening the operation time and increasing the operation safety; on the other hand, it is ensured that the lateral sleeves do not easily slip out of the passage of the handle body 2.
Various structures and arrangements are possible for the fixing portion. For example, the first groove 6 may be provided on the inner wall of the central passage 5, and the first groove 6 may be provided in a direction parallel to the central axis of the central passage 5. The lateral sleeves are fixed by placing them in the first grooves 6. In order to enhance the fixing effect, an interference fit is selected between the lateral sleeve and the first groove 6.
It is also possible, for example, to provide no fixing portion on the central channel 5, but only on one of the lateral sleeve side walls, a catch adapted to the shape of the C-shaped central channel for fixing the lateral sleeve and the handle.
In addition to this, the lateral sleeves can be fixed by providing a C-clip on the inner wall of the central channel 5. Or a fixing buckle 9 can be arranged on the outer wall of the lateral sleeve, and a second groove (not shown in the figure) matched with the fixing buckle is arranged on the inner wall of the central channel to fix the lateral sleeve, so that effective reaming is ensured, the operation time is shortened, and the operation safety is improved.
For the convenience of holding, the holding portion is designed to be a straight shape or a hollow hemisphere shape in the present embodiment, as shown in fig. 3 to 4. Through the design, on one hand, the lateral sleeve is easy to operate in the operation process, on the other hand, the moment and the moment arm are increased, the labor intensity of correcting the bony access is reduced, the reaming speed is increased, and the operation time is shortened.
In consideration of the fact that the grip may block the view during the operation, the grip of the present embodiment is a hollow hemisphere, or the grip is made of a transparent material. The above design facilitates observation of the position and state of the lateral casing during reaming.
In view of the fact that if the gripping portion or the channel is made of a flexible or elastic material, the ability of the handle to power the lateral cannula may be affected by the deformation of the material during the operation, in this embodiment, the gripping portion and the channel are made of a rigid plastic or stainless steel. Above-mentioned design can effectively prevent to reduce the ability that this handle provided power for the side direction sleeve pipe because the passageway warp at the reaming in-process to guarantee this dive formula handle can provide stable and powerful power for the side direction sleeve pipe.
In order to increase the friction force between the grip portion and the hand, the present embodiment is provided with an anti-slip structure on the outer surface of the grip portion. Illustratively, the anti-slip structure may be a protrusion or a groove. Other structures with anti-skid function can also be adopted.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
