Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an endoscope for orthopedics. Background Art

[0002] While the currently widely used rigid endoscopes in orthopedic surgery provide a certain degree of visualization, they still face challenges in practical application. During surgery, bone or other vital tissue often obstructs the view, making direct observation of certain areas difficult. In these cases, effective observation and surgical intervention are difficult without damaging the tissue.

[0003] For example, minimally invasive spinal surgery currently utilizes transforaminal endoscopic lumbar discectomy (PECL) and dual-channel endoscopic techniques. Although these methods are classified as minimally invasive, they inevitably inflict a certain degree of damage to muscle tissue and require partial resection of the spinal articular processes, which can affect spinal stability. However, if an orthopedic soft endoscope could be used to enter the spinal column through the body's natural sacral foramen, tissue damage could be significantly minimized.

[0004] For example, during perforaminal endoscopic lumbar discectomy (PELV), to minimize surgical trauma to the patient, decompression is typically performed on one side before the other side using the same surgical approach. However, existing PELVs lack flexibility, making it difficult to effectively observe the contralateral side of the nerve root, which can result in incomplete decompression.

[0005] For example, during minimally invasive shoulder surgery, due to the spherical structure of the humeral head, traditional rigid arthroscopes often make it difficult to fully observe.

[0006] Based on the above background, there is an urgent need to design an orthopedic endoscope to solve one or more of the above problems, and thus, this application is proposed. Summary of the Invention

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] like Figures 1 to 8 As shown, this embodiment provides an orthopedic endoscope, comprising a handle body 1 and a pipeline assembly 2;

[0046] The pipeline assembly 2 includes a hose section body 21 fixed to the handle body 1, a serpentine section body 22 and an end section body 23, wherein the serpentine section body 22 is located between the hose section body 21 and the end section body 23;

[0047] It also includes a bending drive component that is arranged in the handle body 1 and is used to drive the snake bone segment body 22 to swing and bend. The power output end of the bending drive component is fixedly connected to the end segment body 23.

[0048] This embodiment provides a pipeline assembly 2 having a serpentine segment body 22 and a bending drive assembly that can drive the serpentine segment body 22 to bend, so that during minimally invasive orthopedic surgery, the end segment body 23 can bypass important tissues through the bent serpentine segment body 22, allowing observation and surgery to be performed without damaging the tissues, thereby effectively solving the problem that current orthopedic endoscopes are difficult to directly observe certain positions and have large blind spots.

[0049] Specifically, such as Figure 2 As shown, in this embodiment, the bending drive assembly includes a push rod body 31 rotatably connected to the handle body 1 , and a first cable 34 and a second cable 35 ;

[0050] One end of the first cable 34 and the second cable 35 are respectively fixed to opposite sides of the push rod body 31, and the other ends of the first cable 34 and the second cable 35 are respectively fixed to opposite sides of the end section body 23. By providing the first cable 34 and the second cable 35, the bending drive assembly can pull the first cable 34 or the second cable 35 through the push rod body 31. Since one end of the first cable 34 and the second cable 35 are respectively fixed to opposite sides of the push rod body 31 and the other end are respectively fixed to opposite sides of the end section body 23, when the push rod body 31 pulls the first cable 34, the second cable 35 moves toward the end section body 23, causing the serpentine section body 22 to bend toward the side of the first cable 34. Similarly, when the push rod body 31 pulls the second cable 35, the serpentine section body 22 bends toward the side of the second cable 35.

[0051] Specifically, such as Figure 2 As shown, in this embodiment, the push rod body 31 includes a rotating portion 311 rotatably connected to the handle body 1, and a pushing portion 312 located outside the handle body 1 and fixedly connected to the rotating portion 311. The pushing portion 312 is located outside the body to facilitate operation of the push rod body 31, so that the rotating portion 311 of the push rod body 31 rotates, thereby driving the first cable 34 and the second cable 35 to move.

[0052] Specifically, such as Figure 2 As shown, in this embodiment, the bending drive assembly further includes a first pulley 32 and a second pulley 33 disposed in the handle body 1;

[0053] The first cable 34 is mounted on the first pulley 32;

[0054] The second cable 35 is mounted on the second pulley 33. By providing the first pulley 32 and the second pulley 33, the resistance when the push rod body 31 pulls the first cable 34 or the second cable 35 can be reduced.

[0055] Specifically, the first cable 34 and the second cable 35 are both steel wires.

[0056] Specifically, such as Figure 2 and Figure 4 As shown, the handle body 1 is a hollow structure, and a cavity is provided in the handle body 1;

[0057] The hose section body 21, the serpentine section body 22 and the end section body 23 are respectively provided with a hose section channel 211, a serpentine section channel 221 and an end section channel 231 that are connected;

[0058] The handle section pipeline 5 is provided in the handle body 1 and communicated with the hose section channel 211 . One end of the handle section pipeline 5 away from the hose section channel 211 passes through the handle body 1 .

[0059] By setting up the hose section channel 211, the serpentine section channel 221 and the end section channel 231, as well as the handle section channel 5, and connecting them to each other, the instruments used in minimally invasive orthopedic surgery can enter the surgical position through the channel composed of the hose section channel 211, the serpentine section channel 221, the end section channel 231 and the handle section channel 5.

[0060] Specifically, in this embodiment, Figure 2 and Figure 4 As shown, the handle section pipeline 5 and the hose section channel 211 are coaxially connected;

[0061] The end of the handle body 1 away from the hose section body 21 is provided with a trumpet-shaped instrument inlet 12, and the end of the handle section conduit 5 away from the hose section channel 211 is connected to the trumpet-shaped instrument inlet 12. The trumpet-shaped instrument inlet 12 is provided to facilitate the entry of instruments used in minimally invasive orthopedic surgery into the hose section channel 211.

[0062] Specifically, in this embodiment, Figure 1 and Figure 3 As shown, it also includes a water pipe body 4 connected to the handle section pipeline 5. Two water pipe bodies 4 are provided to facilitate water inlet and outlet.

[0063] Specifically, in this embodiment, Figure 5 As shown, an observation component for observation diagnosis is also included, and the observation component includes:

[0064] A PCB board 61 disposed in the handle body 1, and a lighting module 62 and a camera module 63 electrically connected to the PCB board 61;

[0065] The lighting module 62 and the camera module 63 are both arranged in the end section body 23 of the pipe assembly 2. In this embodiment, the camera module 63 and the PCB board 61 are both existing technologies and are not described here.

[0066] Specifically, in this embodiment, Figure 5 As shown, the lighting module 62 is an LED lamp or an optical fiber. The LED lamp can be set in two or three groups, such as Figure 5 As shown in a and b in the figure, the technicians can set it as needed, which will not be described here. The technicians can also set the lighting module 62 to be an optical fiber, such as Figure 5 As shown in c in the figure, when the lighting module 62 is an optical fiber, an LED lamp is also provided on the PCB to provide a light source, and the light source is transmitted through the optical fiber.

[0067] When using this embodiment, refer to Figure 6 As shown, when performing minimally invasive spinal surgery, the end section body 23 enters the human body through the sacral foramen, and the image transmitted by the camera module 63 is observed through the monitor. After reaching the intervertebral disc that requires surgery, the push rod body 31 is controlled to bend, and then the surgical instrument reaches the patient through the instrument channel composed of the handle section pipe 5, the hose section channel 211, the serpentine section channel 221 and the end section channel 231 to perform surgery. By applying this application, the damage to the surrounding tissues can be significantly reduced, the necessary resection of muscles and other tissues can be reduced, and the invasiveness of the surgery to the patient's body can be reduced. The use of this application not only reduces the patient's postoperative recovery burden, but also improves the safety and effectiveness of the surgery. In addition, the doctor can achieve more precise and gentle surgical operations while protecting the stability of the spine, thereby bringing a better treatment experience to the patient.

[0068] Reference Figure 7 As shown in the figure, during transforaminal endoscopic lumbar discectomy, the unique curved design of this application allows doctors to easily observe nerve compression on the opposite side and precisely insert surgical instruments through the instrument channel to achieve thorough and effective decompression. This technological advancement not only improves surgical safety but also optimizes the patient's postoperative recovery process.

[0069] Reference Figure 8 As shown, when performing minimally invasive shoulder surgery, the product of the present application is used, and its design allows bending, so that every corner of the humeral head of the shoulder joint can be flexibly observed, ensuring the accuracy and safety of the surgery.

[0070] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will be able to make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
