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 retractors and the surgical field of vision provided by endoscopy, precise surgical operations can be achieved 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 rotation, which can lead to unnecessary changes in the surgical field of view provided by the electronic camera and affect the surgical procedure.

[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, locking grooves are formed between the two sides of the anti-rotation limiting part and the outer wall of the rigid protective tube.

[0014] 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.

[0015] 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.

[0036] 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.

[0037] refer to Figures 1-9 This utility model embodiment provides a flexible electronic spinal endoscope, which includes a plug 1, an endoscope hose 2, a rigid protective tube 3, and an electronic camera 4. The rigid protective tube 3 is located at the front end of the endoscope hose 2, the plug 1 is located at the rear end of the endoscope hose 2, and the electronic camera 4 is disposed inside the rigid protective tube 3. The inner side of the rigid protective tube 3 is filled with transparent medical adhesive 6 (transparency helps to set up an LED light source module to provide illumination). The rigid protective tube 3 and the electronic camera 4 are fixed together by the medical adhesive 6. A raised anti-rotation limiting part 31 is provided on one side of the outer wall of the rigid protective tube 3. Besides... Figure 1 , Figure 5 , Figure 6 In this case, plug 1 can also be a USB connector.

[0038] Among them, the anti-rotation limiting part 31 is located on the outer wall of the rigid protective tube 3, and can be used to cooperate with external auxiliary devices to prevent the rigid protective tube 3 from rotating, thereby preventing the electronic camera 4 from rotating, which helps to avoid unnecessary changes in the field of view of the electronic camera 4.

[0039] Specifically, the rigid protective tube 3 can be made of steel. The anti-rotation limiting part 31 is integrally formed with the rigid protective tube 3; or, the anti-rotation limiting part 31 can also be welded to the rigid protective tube 3.

[0040] Specifically, the anti-rotation limiting part 31 has multiple implementations. For example, such as Figure 1 The anti-rotation limiting part 31 can be a continuous protruding structure that extends axially along the rigid protective tube 3; or, as... Figure 5 The anti-rotation limiting part 31 can be a plurality of protruding structures spaced apart, and the plurality of protruding structures are arranged along the axial direction of the rigid protective tube 3. Additionally, as... Figure 6 and Figure 7 As shown, locking grooves 32 can be formed between the two sides of the anti-rotation limiting part 31 and the outer wall of the rigid protective tube 3. Regarding the endoscope mounting groove on the working sleeve or retractor, the mounting groove can usually be set as a C-shaped groove. The C-shaped groove 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.

[0041] In the flexible electronic spinal endoscope of this embodiment, the endoscope tube 2 includes an outer tube 21 and wires 22 and molding wires 23 disposed inside the outer tube 21. Specifically, the wires 22 should include an insulating layer and a conductor (e.g., copper wire) wrapped inside the insulating layer, and the molding wires 23 can be steel or aluminum wires. There can be multiple wires 22, with the molding wires 23 disposed in the middle, and these wires 22 arranged around the outer periphery of the molding wires 23. The molding capability provided by the molding wires, such as steel or aluminum wires, allows the endoscope tube 2 to be bent and shaped 360 degrees. That is, the endoscope tube 2 can be bent by external force, and the shape formed by bending can be fixed, thus playing a role in shaping (fixing shape) and positioning (fixing position). During the operation, the endoscope tube 2 can be bent and positioned at any position, providing great flexibility for adjusting the tube's path and effectively avoiding obstruction of the surgical procedure.

[0042] In the flexible electronic spinal endoscope of this embodiment, a circuit board 5 is also provided inside the rigid protective tube 3. The electronic camera 4 is mounted on the circuit board 5, and the wire 22 is connected to the circuit board 5, 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, circuit board 5, and wire 22 are all cured together with medical adhesive 6. The medical adhesive 6 serves to fix, seal, and insulate, allowing the endoscope to be used in working environments with liquid media (such as physiological saline).

[0043] In the flexible electronic spinal endoscope of this utility model embodiment, such as Figure 8 and Figure 9 As shown, a rigid limiting tube 7 can be connected to the rear end of the rigid protective tube 3. The rigid limiting tube 7 is bent in an L-shape relative to the rigid protective tube 3 and is connected to the front end of the endoscope flexible tube 2. The rigid limiting tube 7 and the rigid protective tube 3 can be integrally formed or welded together. The rigid limiting tube 7 can limit the installation depth of the endoscope, further facilitating its use.

[0044] In such Figure 8 and Figure 9 In 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 33. 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 33, and the rigid limiting tube 7 is bent towards the straight side of the angle 33. 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 7 is bent towards the straight side of the angle 33, which allows the rigid limiting tube 7 to not only limit the depth but also indicate the direction of the endoscope's field of view.

[0045] Figures 1-9 The flexible electronic spinal endoscopes of the various embodiments shown can be used as a reference to each other.

[0046] 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.
