Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a flexible electronic spinal endoscope. Background Technology
[0002] With the development of precision medicine, the precision and minimally invasive nature of spinal surgery are becoming increasingly popular. By using working cannulas or retractors, and with the surgical field provided by endoscopy, precise surgical procedures can be performed with smaller incisions.
[0003] Currently, there are very few flexible electronic spinal endoscopes on the market that can be used with auxiliary exposure instruments such as working cannulas or retractors. This is mainly because when a flexible electronic spinal endoscope is installed on these auxiliary instruments, the tip of the endoscope (i.e., the part with the electronic camera) is prone to axial movement. In most cases, this manifests as the endoscope moving up and down, causing unnecessary changes in the surgical field of view provided by the electronic camera and affecting the surgical procedure. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a flexible electronic spinal endoscope that can effectively prevent axial displacement.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A flexible electronic spinal endoscope includes an endoscope hose, a rigid protective tube, an electronic camera, and a magnet. The rigid protective tube is located at the front end of the endoscope hose, and a damping part is provided on the outer wall of the rigid protective tube. The electronic camera and the magnet are located on the inner side of the rigid protective tube.
[0007] Furthermore, the inner side of the rigid protective tube is filled with medical adhesive, and the rigid protective tube, electronic camera, and magnet are cured together by the medical adhesive.
[0008] Furthermore, the damping part is annular, and the outer wall of the rigid protective tube is provided with an annular groove, in which the damping part is disposed.
[0009] Furthermore, the magnet is elongated; the cross-section of the magnet is an arc-shaped structure, a circular structure, or a square structure.
[0010] Furthermore, a raised anti-rotation limiting part is provided on one side of the outer wall of the rigid protective tube.
[0011] Furthermore, the anti-rotation limiting part is a continuous protruding structure that extends along the axial direction of the rigid protective tube.
[0012] Alternatively, the anti-rotation limiting part may be a plurality of protruding structures spaced apart, the plurality of protruding structures being arranged along the axial direction of the rigid protective tube.
[0013] Furthermore, the endoscope hose includes an outer tube and wires and molding wires disposed inside the outer tube.
[0014] Furthermore, the flexible electronic spinal endoscope also includes a flexible liquid line that extends into the interior of the endoscope flexible tube. The front end of the liquid line extends to the front end of the inner side of the rigid protective tube, and the rear end of the liquid line is connected to a sealing joint located on the outside of the endoscope flexible tube.
[0015] Furthermore, a rigid limiting tube is connected to the rear end of the rigid protective tube. The rigid limiting tube is bent in an L-shape relative to the rigid protective tube and is connected to the front end of the endoscope flexible tube.
[0016] Furthermore, the electronic camera is located at the front end inside the rigid protective tube, the front end of the rigid protective tube forms an angle, the field of view of the electronic camera is tilted towards the hypotenuse of the angle, and the rigid limiting tube is bent towards the straight side of the angle.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The flexible electronic spinal endoscope provided by this utility model has a damping part on the outer wall of the rigid protective tube at its front end, and an electronic camera and a magnet are arranged on the inner side of the rigid protective tube. When the rigid protective tube is installed in the endoscope mounting slot of the external auxiliary instrument, since the auxiliary instrument is usually made of metal that can be attracted by a magnet, the magnet can generate an attraction force on the inner wall of the mounting slot through the rigid protective tube, thereby providing pressure to press the damping part against the inner wall of the mounting slot, thereby generating a frictional force to prevent axial movement. This can effectively prevent the endoscope from moving up and down, and help avoid unnecessary changes in the field of view of the electronic camera. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] refer to Figures 1-8 This utility model provides a flexible electronic spinal endoscope, which includes a plug 1, an endoscope hose 2, a rigid protective tube 3, an electronic camera 4, and a magnet 5. The rigid protective tube 3 is located at the front end of the endoscope hose 2, and the plug 1 is located at the rear end of the endoscope hose 2. A damping part 31 is provided on the outer wall of the rigid protective tube 3. The electronic camera 4 and the magnet 5 are located on the inner side of the rigid protective tube 3. The inner side of the rigid protective tube 3 is filled with transparent medical adhesive 7 (transparency helps to set up the LED light source module to provide illumination). The rigid protective tube 3, the electronic camera 4, and the magnet 5 are fixed together by the medical adhesive 7.
[0031] When the rigid protective tube 3 is installed in the endoscope mounting slot of the external auxiliary instrument, since the auxiliary instrument is usually made of metal that can be attracted by the magnet 5, the magnet 5 can generate an attraction force on the inner wall of the mounting slot through the rigid protective tube 3, thereby providing pressure to press the damping part 31 against the inner wall of the mounting slot, thereby generating a frictional force to prevent axial movement. This can effectively prevent the endoscope from moving up and down and help avoid unnecessary changes in the field of view of the electronic camera.
[0032] Specifically, the damping part 31 is annular, and the outer wall of the rigid protective tube 3 is provided with an annular groove 32, in which the damping part 31 is disposed. The annular groove 32 prevents the damping part 31 from moving axially relative to the rigid protective tube 3.
[0033] Specifically, magnet 5 is elongated. The cross-section of magnet 5 is arc-shaped, adaptable to the circular structure of rigid protective tube 3. Alternatively, the cross-section of magnet 5 can also be circular or square (including square and rectangular). Rigid protective tube 3 can be made of circular steel tubing.
[0034] Specifically, a raised anti-rotation limiting part 33 is provided on one side of the outer wall of the rigid protective tube 3. The anti-rotation limiting part 33 can be integrally formed with the rigid protective tube 3; or, the anti-rotation limiting part 33 can be welded to the rigid protective tube 3.
[0035] Alternatively, the anti-rotation limiting part 33 can be a continuous protrusion structure that extends along the axial direction of the rigid protective tube 3; or, the anti-rotation limiting part 33 can also be a plurality of protrusion structures that are spaced apart and arranged along the axial direction of the rigid protective tube 3.
[0036] The anti-rotation limiting part 33 is located on the outer wall of the rigid protective tube 3. It can be used to cooperate with external auxiliary instruments to prevent the rigid protective tube 3 from rotating, thereby preventing the electronic camera 4 from rotating and helping to avoid unnecessary changes in the field of view of the electronic camera 4. Regarding the endoscope mounting slot on auxiliary instruments such as the working sleeve or retractor, the mounting slot can usually be set as a C-shaped slot. The C-shaped slot has a groove structure that matches the width of the anti-rotation limiting part, which is used to slide with the anti-rotation limiting part, so as to play the role of anti-rotation limiting and will not hinder the installation and use of the endoscope.
[0037] In the flexible electronic spinal endoscope of this utility model embodiment, the endoscope hose 2 includes an outer tube 21 and a wire 22 and a shaping wire 23 disposed inside the outer tube 21; wherein, the shaping wire 23 is used to provide shaping capability for the endoscope hose 2.
[0038] Specifically, the lead wire 22 should include an insulating layer and a conductive material (e.g., copper wire) wrapped inside the insulating layer. The shaping wire 23 can be made of steel or aluminum wire. There can be multiple lead wires 22, with the shaping wire 23 positioned in the middle, and these lead wires 22 arranged around the outer periphery of the shaping wire 23. The shaping capability provided by the shaping wire (such as steel or aluminum wire) allows the endoscopic flexible tube 2 to be bent and shaped 360 degrees. That is, the endoscopic flexible tube 2 can be bent by external force, and the resulting shape can be fixed, thus serving the functions of shaping (fixing shape) and positioning (fixing position). During the operation, the endoscopic flexible tube 2 can be bent and positioned at any point, providing great flexibility for adjusting the tube's path and effectively avoiding obstruction of the surgical procedure.
[0039] In the flexible electronic spinal endoscope of this embodiment, a circuit board 6 is also provided inside the rigid protective tube 3. The electronic camera 4 is mounted on the circuit board 6, and the wire 22 is connected to the circuit board 6, forming an electrical connection with the electronic camera 4. The wire 22 is used to transmit electrical signals and image signals. The rigid protective tube 3, electronic camera 4, magnet 5, circuit board 6, and wire 22 are all cured together with medical adhesive 7. The medical adhesive 7 plays a role in fixing, sealing, and insulating, enabling the endoscope to be adapted to working environments with liquid media (such as physiological saline).
[0040] The flexible electronic spinal endoscope of this utility model embodiment may further include a flexible liquid line 8 (fixed by medical adhesive 7, but the front opening of the liquid line 8 is not sealed), the liquid line 8 is inserted into the interior of the endoscope flexible tube 2, the front end of the liquid line 8 extends to the front end of the inner side of the rigid protective tube 3, and the rear end of the liquid line 8 is connected to a sealing connector 81, which is located on the outside of the endoscope flexible tube 2.
[0041] The sealing connector 81 can be used as a water inlet for cleaning the lens, or as a negative pressure suction port for drawing out smoke or sewage.
[0042] In the flexible electronic spinal endoscope of this embodiment, reference Figure 7 The rear end of the rigid protective tube 3 can be connected to a rigid limiting tube 9, which is L-shaped relative to the rigid protective tube 3 and connected to the front end of the endoscope flexible tube 2. The rigid limiting tube 9 and the rigid protective tube 3 can be integrally formed or welded together. The rigid limiting tube 9 limits the installation depth of the endoscope, further facilitating its use.
[0043] In such Figure 7 and Figure 8In the flexible electronic spinal endoscope shown, the electronic camera 4 is located at the front end inside the rigid protective tube 3. The front end of the rigid protective tube 3 forms an angle 34. The field of view of the electronic camera 4 (which can be understood as the direction of the center line of the field of view) is tilted towards the hypotenuse of the angle 34, and the rigid limiting tube 9 is bent towards the straight side of the angle 34. This arrangement allows the electronic camera 4 to observe the surgical area at an angle. Since the components of auxiliary instruments such as working cannulas and retractors that act on the human body are usually located around or on both sides of the surgical area, when the endoscope is mounted on the components that act on the human body, observing the surgical area at an angle allows the camera or photographing angle to be more adapted to the position of the surgical area, improving the field of view. In addition, the rigid limiting tube 9 is bent towards the straight side of the angle 34, which allows the rigid limiting tube 9 to not only limit the depth but also indicate the direction of the endoscope's field of view.
[0044] Figures 1-8 The flexible electronic spinal endoscopes of the various embodiments shown can be used as a reference to each other.
[0045] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
