Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a working channel for a flexible electronic spinal endoscope. Background Technology

[0002] Currently, flexible electronic spinal endoscopes are increasingly widely used in minimally invasive spinal surgery due to their flexibility. However, existing working channels have many limitations. For example, CN116983066B discloses a spinal working channel based on a flexible electronic endoscope, which has an outer sheath, a sheath channel for introducing and fixing the outer sheath, and an assembly ring. The sheath channel is assembled to the assembly ring, which is detachable and can rotate 360° to be assembled to the upper end face of the outer sheath. The outer sheath forms a working channel to facilitate surgical operations. However, this working channel structure formed by the outer sheath is rigid and has poor adaptability. When dealing with complex anatomical structures, it is impossible to flexibly change the channel shape to approach the surgical operating area, thus limiting the choice of surgical approach.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-6 This embodiment provides a flexible electronic spinal endoscope working channel, including a first half-sleeve 1, a second half-sleeve 2, and an endoscope channel 3. The first half-sleeve 1 and the second half-sleeve 2 are detachably connected to form a working channel 4, and the endoscope channel 3 is movably mounted on the inner wall of either the first half-sleeve 1 or the second half-sleeve 2 along the circumference of the working channel 4.

[0026] The detachable connection between the first half-sleeve 1 and the second half-sleeve 2 allows for separate use of each, enabling flexible selection of either half-sleeve 1 or half-sleeve 2, or their combination, depending on the surgical scenario (e.g., treating specific bony or soft tissue anatomical structures). This expands the range of surgical applications. The endoscope channel 3 is circumferentially movable along the working channel 4. During surgery, the endoscope channel 3 can be flexibly slid according to different angles and field of view requirements, adjusting the position and angle of the electronic endoscope within it to expand the surgical field of view and adapt to varying surgical needs.

[0027] Furthermore, the first half-sleeve 1 includes a first arc-shaped edge 11, and the second half-sleeve 2 includes a second arc-shaped edge 21. One of the first arc-shaped edge 11 and the second arc-shaped edge 21 has a plug-in portion 5 at both ends, and the other has corresponding insertion holes 6 at both ends. The plug-in portion 5 can be inserted into or removed from the insertion hole 6 to detachably connect the first half-sleeve 1 and the second half-sleeve 2. In this embodiment, the plug-in portion 5 is located on the lower end face of the first arc-shaped edge 11, and the insertion holes 6 are correspondingly located at both ends of the second arc-shaped edge 21. The plug-in portion 5 has a columnar structure, and its axial direction is parallel to the axial direction of the first half-sleeve 1. The plug-in portion 5 can be inserted into or removed from the insertion hole 6 along its own axial direction. Thus, through the cooperation of the plug-in portion 5 and the insertion hole 6, the connection between the first half-sleeve 1 and the second half-sleeve 2 can be stable. In other embodiments, the axial direction of the plug-in portion 5 can also be perpendicular to the first half-sleeve 1, but this connection method is not stable enough in the radial direction of the working channel 4 and may result in detachment.

[0028] Furthermore, a silicone layer is fixed to the inner wall of the socket 6 and / or the outer wall of the insertion part 5. The silicone layer provides an interference fit between the insertion part 5 and the socket 6, thereby further improving the axial connection stability between the first half-sleeve 1 and the second half-sleeve 2, and making it easier to disassemble the first half-sleeve 1 and the second half-sleeve 2.

[0029] Furthermore, a first inclined portion 12 is provided on the side of the first half-sleeve 1 away from the first arc-shaped edge 11, and a second inclined portion 22 is provided on the side of the second half-sleeve 2 away from the second arc-shaped edge 21. The first inclined portion 12 and the second inclined portion 22 are configured such that when the first half-sleeve 1 and the second half-sleeve 2 are connected together, the first inclined portion 12 and the second inclined portion 22 are positioned opposite each other, with the upper inclined end of the first inclined portion 12 abutting against the upper inclined end of the second inclined portion 22, and the lower inclined end of the first inclined portion 12 moving away from the lower inclined end of the second inclined portion 22. Thus, in the working channel 4 formed after the first half-sleeve 1 and the second half-sleeve 2 are connected, the gap between the opposing first inclined portion 12 and the second inclined portion 22 forms a visual exposure area, effectively conforming to the protruding bony or soft tissue anatomical structures during surgery, facilitating surgical operations.

[0030] Furthermore, the first half-sleeve 1 is provided with a first handle 13, which extends radially outward along the first half-sleeve 1. The first handle 13 includes an inclined section 131 and a horizontal section 132. The inclined section 131 is inclined away from the axial direction of the first half-sleeve 1, and its inclined lower end is connected to the first arc-shaped edge 11 of the first half-sleeve 1, while its inclined upper end is connected to the horizontal section 132. The second half-sleeve 2 is provided with a second handle 23, which has the same structure as the first handle 13. The inclined section makes the working channel 4 more ergonomic.

[0031] Furthermore, the first handle 13 and the second handle 23 are configured such that when the first half-sleeve 1 is connected to the second half-sleeve 2, the first handle 13 and the second handle 23 are positioned opposite each other. This dual-handle layout facilitates stable manipulation of the channel by the surgeon during the procedure, distributes hand stress, reduces tremors, and maintains surgical stability.

[0032] Furthermore, refer to Figure 5 and Figure 6 The entire endoscope channel 3 is fitted against the inner wall of the working channel 4. A baffle 31 is provided at the edge of the endoscope channel 3 extending into the working channel 4, and the baffle 31 is fitted against the inner wall of the working channel 4. The baffle 31 effectively isolates the operating area from nerve tissue, protecting the nerve during the operation and preventing accidental nerve damage from instruments or the endoscope.

[0033] Furthermore, the endoscope channel 3 is equipped with a hook 32, which is used to hook onto the first arc-shaped edge 11 or the second arc-shaped edge 21. The hook 32 can move circumferentially along the first arc-shaped edge 11 or the second arc-shaped edge 21. In this way, the endoscope channel 3 can be mounted on the first half-sleeve 1 or the second half-sleeve 2, and can be used in conjunction with a single half-sleeve. During the operation, the endoscope channel 3 can be flexibly slid according to different angles and field of vision requirements, thereby adjusting the position and angle of the electronic endoscope located in the endoscope channel 3, expanding the coverage of the surgical field of vision, and adapting to the changing needs of surgical operations.

[0034] Furthermore, a limit button 33 is provided on the endoscope channel 3. The portion of the limit button 33 that extends into the endoscope channel 3 has a flexible part for contacting the electronic endoscope. The flexible part can be made of silicone. The pressing structure of the limit button 33 is existing technology and will not be described in detail. By pressing the limit button 33, the electronic endoscope in the endoscope channel 3 can be fixed. The flexible clamping of the silicone effectively limits the displacement and shaking of the electronic endoscope, protecting it from rigid compression damage, while also maintaining the stability of the electronic endoscope, ensuring a clear surgical field and precise operation.

[0035] In addition, the entire working channel 4 is mainly made of titanium alloy. Titanium alloy has the characteristics of high strength and low density, which makes the working channel 4 lightweight and easy to operate, reducing the fatigue of the surgeon holding it for a long time, allowing the surgeon to focus more on the surgical operation, improving surgical accuracy and surgeon comfort; at the same time, it has good biocompatibility and corrosion resistance, and can be used stably in the surgical environment for a long time, ensuring channel performance and surgical safety.

[0036] When assembling the working channel 4, check the integrity and precision of each component. Align the insertion part 5 on the first half-sleeve 1 with the insertion hole 6 on the second half-sleeve 2, slowly insert it, and confirm that the two fit tightly. Hook 32 on the endoscope channel 3 onto the first arc-shaped edge 11 or the second arc-shaped edge 21, and confirm that the hook 32 slides smoothly on the first arc-shaped edge 11 or the second arc-shaped edge 21 without any jamming; test whether the pressing limit button 33 has normal pressing limit and rebound release functions.

[0037] During the surgical procedure, gently insert the assembled working channel 4 into the surgical site. Depending on the needs of the surgical scenario, select to use a single half-sleeve or the combined working channel 4 for the operation (e.g., when treating a lesion on one side, try using the corresponding half-sleeve close to the operating area). Insert the flexible electronic endoscope into the endoscope channel 3 and press the limit button 33 to fix the endoscope. If it is necessary to adjust the angle and field of view of the endoscope, move the hook 32 around the working channel 4 to adjust the endoscope to the appropriate position and angle before performing the surgical operation. Use the baffle 31 to protect the nerves during the movement. After the surgery, disassemble the components in the reverse order of assembly, and perform cleaning, disinfection, and sterilization for future use.

[0038] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
