Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a full-view spinal electronic endoscope system. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Spinal endoscopy is a minimally invasive surgical technique that has been widely used in the field of spinal surgery in recent years. From its initial application in treating lumbar disc herniation, it has gradually expanded to treat various diseases such as lumbar spinal stenosis, ossification of the ligamentum flavum in the thoracic spine, and cervical spondylosis, and has even been applied to spinal fusion surgery. Its core advantages lie in its minimal trauma, less bleeding, and faster recovery, leading it to gradually replace some traditional open surgeries in clinical practice.

[0004] Current spinal endoscopic techniques mainly include single-channel and dual-channel techniques. Dual-channel endoscopy includes an observation channel for illumination and imaging, and an operating channel for instrument insertion. The separation of the operating and imaging channels provides greater surgical space; however, dual-channel endoscopy requires two incisions, resulting in significantly greater tissue damage than single-channel endoscopy. Single-channel endoscopy integrates observation and manipulation within a single channel, with instruments entering through the endoscope's working channel. While less invasive, it requires specialized, delicate surgical instruments, leading to lower efficiency and is primarily used for simple disc herniation. Furthermore, both single-channel and dual-channel techniques rely on a single optical endoscope, making the operating field of view susceptible to obstruction by instruments, creating blind spots and increasing surgical risks. Additionally, surgeons must hold the endoscope module with one hand and operate instruments with the other, leading to fatigue and increased safety risks. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a full-view spinal electronic endoscope system that overcomes the defects of current spinal endoscope equipment.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] An embodiment of the present invention provides a full-view spinal electronic endoscope system, including a retractor. Both retractor ends are connected to the top of baffles. The two baffles are arranged opposite each other, forming a channel for surgical instruments to enter. The baffles are connected to an angle adjustment mechanism located at the retractor end, which adjusts the angle of the baffles. Each baffle has an electronic endoscope mounting channel inside, and an electronic endoscope is embedded within the channel. The lens of the electronic endoscope is exposed from the bottom of the inner side of the baffle to acquire images of the surgical area. The electronic endoscope is connected to an image processing host, enabling the transmission of acquired images to the host.

[0008] Optionally, the angle adjustment mechanism includes a connecting sleeve fixed to the opening end of the spreader. Correspondingly, a rotating shaft passes through the connecting sleeve and is rotatably connected to the connecting sleeve. The rotating shaft is connected to the top end of the baffle. A locking component is provided between the rotating shaft and the opening end of the spreader to lock and fix the baffle to the opening end of the spreader.

[0009] Optionally, the locking assembly uses a locking screw threaded onto the connecting sleeve, and the locking screw can abut against the shaft surface to lock and fix the shaft and the spreader.

[0010] Optionally, the rotating shaft is provided with a gear ring, and the opening end of the spreader is provided with a gear that meshes with the gear ring. The gear is fixedly connected to the wheel frame, and the wheel frame is elastically connected to the opening end of the spreader.

[0011] Optionally, a connecting plate is vertically provided at the top of the baffle, and the connecting plate is detachably and fixedly connected to the shaft surface.

[0012] Optionally, the axis of the electronic endoscope channel is inclined to the axis of the baffle, the bottom end of the electronic endoscope channel extends to the bottom of the inner side of the baffle to form an opening for exposing the lens of the electronic endoscope, and part of the opening formed at the top of the electronic endoscope channel is located on the top surface of the baffle and part of it is located on the top surface of the connecting plate.

[0013] Optionally, the rotating shaft is provided with a rotating operation shaft section, the cross section of which is a regular polygon that matches the wrench.

[0014] Optionally, the baffle is also provided with flushing channels on both sides of the electronic endoscope channel. The flushing channels are completely embedded inside the baffle. The cross-section of the flushing channel perpendicular to its extension direction is elliptical. The bottom end of the flushing channel extends to the bottom of the inner side of the baffle to form a water outlet.

[0015] Optionally, the electronic endoscope module is detachably installed inside the electronic endoscope installation channel. Correspondingly, the top surface of the baffle is provided with elastic clips on both sides of the inlet of the electronic endoscope installation channel, and the elastic clips hold and fix the top of the electronic endoscope module.

[0016] Optionally, the two baffles have the same shape and size, and both baffles adopt a semi-circular arc structure.

[0017] The beneficial effects of this invention are as follows:

[0018] The open spinal electronic endoscope system of the present invention has baffles at the opening end of the spreader. The baffles are used to extend into human tissue to form a surgical channel. The two baffles are arranged opposite each other and each baffle is equipped with an electronic endoscope. The two electronic endoscopes can acquire images of the surgical operation area from all directions, realize full-view observation of the surgical operation area, and the surgical instruments will not affect the field of vision of the surgical operation area, which facilitates the operation of the surgeon, improves the safety of the operation, and reduces the incidence of complications.

[0019] The baffles are connected to the opening end of the retractor via an angle adjustment mechanism. The angles of the two baffles can be adjusted, and the retractor can also adjust the expansion of the two baffles. This allows for adjustment of the space between the two baffles for inserting surgical instruments, reducing the restriction on the operation of surgical instruments and further facilitating the operation of surgical instruments by the surgeon.

[0020] The baffle is connected to the retractor. During actual surgery, the retractor can be placed on the patient's back to fix the electronic endoscope, thereby allowing the surgeon to operate the surgical instruments with both hands, improving surgical efficiency and safety.

[0029] Example 1

[0030] This embodiment provides a full-view spinal electronic endoscopy system, including a spreader, a baffle, an electronic endoscope, an image processing host, etc.

[0031] The retractor is an improvement on the existing surgical retractor and includes two retractor clamps, namely the first retractor clamp 1 and the second retractor clamp 2. The first retractor clamp 1 and the second retractor clamp 2 are hinged at the middle position by a hinge shaft. One end of the first retractor clamp 1 and the second retractor clamp 2 serves as the retractor end, and the other end is provided with a handle 3, which adopts a ring structure.

[0032] Among them, the part of the first spreading clamp 1 and the second spreading clamp 2 located between the hinge shaft and the spreading end adopts an arc-shaped structure that bulges outward, while the part between the hinge shaft and the handle 3 adopts a straight structure.

[0033] A locking assembly is provided between the linear structures of the first spreading clamp 1 and the second spreading clamp 2. The locking assembly is used to lock and fix the first spreading clamp 1 and the second spreading clamp 2.

[0034] Specifically, the locking assembly includes an arc-shaped strip 4, one end of which is fixed to the first spreading clamp 1. The outer arc surface of the arc-shaped strip 4 is provided with a rack. The second spreading clamp 2 is rotatably connected to a locking member 5. The locking member 5 is provided with locking teeth, which cooperate with the rack. The locking member 5 also contacts an elastic piece 6 fixed to the second spreading clamp 2. The elastic force of the elastic piece 6 causes the locking teeth of the locking member to cooperate with the rack.

[0035] When the user rotates the first opening clamp 1 and the second opening clamp 2 relative to each other, under the action of external force, the locking teeth of the locking member 5 overcome the elastic force of the elastic piece 6 and disengage from the tooth groove of the rack, so that the first opening clamp 1 and the second opening clamp 2 can rotate relative to each other. When the first opening clamp 1 and the second opening clamp 2 are rotated into place and the external force is removed, the locking teeth are inserted into the tooth groove of the rack, and the elastic force of the elastic piece 6 is used to lock and fix the first opening clamp 1 and the second opening clamp 2.

[0036] The structure of the expander described above can be achieved using existing technology, and its further technical details will not be described in detail here. This embodiment only improves the expanding end of the expander, specifically:

[0037] The first and second opening clamps 1 and 2 are both equipped with angle adjustment mechanisms at their opening ends, and the angle adjustment mechanisms are connected to the top of the baffle.

[0038] In this embodiment, the angle adjustment mechanism is directly set on the upper surface of the opening end of the spreading clamp, without modifying the rest of the structure of the spreading clamp. The angle adjustment mechanism includes a connecting sleeve 7, a rotating shaft 8, and a locking assembly. Specifically:

[0039] A connecting sleeve 7 is provided on the upper surface of the opening end of the first spreading clamp 1 and the second spreading clamp 2. The connecting sleeve 7 is connected to one end of the bracket 9, and the other end of the bracket 9 is connected to the upper surface of the opening end of the spreading clamp to fix the connecting sleeve 7 to the opening end of the spreading clamp.

[0040] The connecting sleeve 7 passes through the rotating shaft 8, and the rotating shaft 8 is rotatably connected to the connecting sleeve 7 so that the rotating shaft 8 can rotate around its own axis. The axial surface of the rotating shaft 8 is detachably fixed to the top of the baffle 16. The rotating shaft 8 can drive the baffle 16 to swing around its own axis, thereby realizing the adjustment of the angle of the baffle 16.

[0041] Furthermore, in order to enable axial positioning between the rotating shaft 8 and the connecting sleeve 7, an annular groove is provided on the axial surface of the rotating shaft 8, and the connecting sleeve 7 is sleeved on the outer circumference of the groove surface. Through the cooperation of the annular groove and the connecting sleeve 7, the rotating shaft 8 and the connecting sleeve 7 are axially positioned. The rotating shaft 8 can only rotate around its own axis and will not produce linear motion along its own axis.

[0042] A locking component is provided between the rotating shaft 8 and the opening end of the spreading pliers. The locking component is used to lock and fix the rotating shaft 8. In this embodiment, the locking component is set between the rotating shaft 8 and the connecting sleeve 7, or directly between the rotating shaft 8 and the opening end of the spreading pliers.

[0043] In one embodiment, a locking assembly is disposed between the rotating shaft 8 and the connecting sleeve 7. The locking assembly uses a locking screw, which is threaded to the wall of the connecting sleeve 7. When the locking screw is rotated, it abuts against the axial surface of the rotating shaft 8, thereby pressing the rotating shaft 8 and locking the rotating shaft 8 to the connecting sleeve 7. This achieves the locking and fixing of the rotating shaft 8 to the opening end of the spreading pliers.

[0044] In another embodiment, the locking component is disposed between the rotating shaft 8 and the opening end of the spreading clamp. Specifically, the rotating shaft 8 is provided with a gear ring 10, which meshes with a gear 11. The gear 11 is fixedly connected to the wheel frame 12, and the wheel frame 12 is elastically connected to the opening end of the spreading clamp.

[0045] Specifically, one end of the wheel frame 12 is connected to the spring 13, and the other end of the spring 13 is connected to the surface of the spreading end. The wheel frame 12 is slidably connected to the guide rail 14 provided on the surface of the spreading end. In this embodiment, when the rotating shaft 8 is rotated by an external force, the gear 11 can overcome the elastic force of the spring 13 and move towards the spreading end of the spreading clamp, thereby enabling the rotating shaft 8 to rotate. When the rotating shaft 8 is rotated to the position and is not subject to external force, under the action of the elastic force of the spring 13, the gear 11 meshes with the gear ring 10. The rotating shaft 8 is locked and fixed by the elastic force of the spring 13 and the meshing of the gear 11 and the gear ring 10. This method makes the operation more convenient.

[0046] Those skilled in the art can choose the specific method of locking components according to actual needs, which will not be described in detail here.

[0047] Furthermore, since the size of the rotating shaft 8 is small, it is inconvenient for the surgeon to directly rotate the rotating shaft 8 by hand. Therefore, an operating shaft section 15 is provided on the rotating shaft 8. The cross-section of the operating shaft section 15 adopts a regular polygonal shape that matches the wrench. Preferably, the shaft surface of the operating shaft section 15 adopts a regular hexagonal shape, which makes it convenient for the surgeon to rotate the rotating shaft using a wrench.

[0048] The rotating shaft 8 is detachably and fixedly connected to the top of the baffle 16. The rotating shaft 8 can drive the baffle 16 to swing. Specifically:

[0049] The baffle 16 is a semi-circular arc plate. A connecting plate 17 is provided at the top of the outer arc surface of the baffle 16. The connecting plate 17 is perpendicular to the baffle 16. The upper surface of the connecting plate 17 is provided with a bearing seat 18 that matches the rotating shaft 8. After the rotating shaft 8 is attached to the bearing seat 18, multiple fixing bolts 19 pass through the bearing seat 18 and the connecting plate 17. The fixing bolts 19 are threaded with fixing nuts 20. The fixing nuts 20 are attached to the bottom surface of the connecting plate 17, thereby realizing the detachable fixed connection between the connecting plate 17 and the rotating shaft 8.

[0050] Furthermore, a groove is provided in the axial surface area of ​​the rotating shaft 8 passing through the fixing bolt 19, and the groove surface fits against the head of the fixing bolt 19.

[0051] It is understood that the connecting plate 17 can also be detachably and fixedly connected to the rotating shaft 8 through a clamp structure. Those skilled in the art can choose the connection method between the connecting plate 17 and the rotating shaft 8 according to actual needs, which will not be described in detail here.

[0052] Since the baffle 16 and the rotating shaft 8 are detachably and fixedly connected, a series of baffles 16 of different sizes can be made. When using them, the appropriate baffle 16 can be selected according to the patient's body shape and fixedly connected to the rotating shaft 8.

[0053] The baffle 16 connected to the first dispersing forceps 1 and the second dispersing forceps 2 can form a channel for accommodating surgical instruments. The surgical instruments include nucleus pulposus forceps, radiofrequency ablation electrodes, trephine, bone drill, laminar bone biting forceps, trephine saw, bone scalpel, etc. Those skilled in the art can select the corresponding surgical instruments according to actual needs, which will not be described in detail here.

[0054] Both of the baffles 16 connected to the two spreading clamps are equipped with electronic endoscope installation channels, preferably, such as Figure 5 As shown, the axis of the electronic endoscope mounting channel is set at an acute angle to the axis of the baffle 16 and is inclined towards the inside of the baffle 16. The top of the electronic endoscope mounting channel extends to the top surface of the baffle 16 and the connecting plate 17, forming an opening. Part of the opening is located on the top surface of the baffle 16 and part is located on the top surface of the connecting plate 17. The bottom end extends to the bottom end of the inner arc surface of the baffle 16. An electronic endoscope 21 is inserted into the electronic endoscope mounting channel, thereby realizing the embedding and installation of the electronic endoscope 21 in the baffle 16. The lens of the electronic endoscope 21 is exposed in the opening formed at the bottom end of the inner arc surface of the baffle 16 to realize the acquisition of images of the surgical area.

[0055] In this embodiment, because the electronic endoscope installation channel is tilted, the electronic endoscope 21 does not need to be fully embedded in the baffle 16, so that the thickness of the baffle 16 can be minimized as much as possible. The thickness of the baffle 16 is allowed to be less than the diameter of the electronic endoscope 21. While ensuring the surgical operating space, the degree of soft tissue distension is minimized, and trauma to the patient is reduced.

[0056] The electronic endoscope 21 can be any electronic endoscope used in the current spinal endoscope system. Its specific structure will not be described in detail here. The electronic endoscope 21 is connected to the image processing host via a circuit. The image processing host displays the image of the surgical area, which facilitates the operation of the surgeon.

[0057] Both the electronic endoscope 21 and the image processing host can be based on existing technologies, and further technical details will not be described in detail here.

[0058] In this embodiment, since both baffles are embedded with electronic endoscopes 21, the two electronic endoscopes 21 can collect images of the surgical operation area from all directions, and the surgical instruments will not affect the field of vision of the surgical operation area, making it convenient for the surgeon to operate.

[0059] Furthermore, the baffle 16 is also provided with a flushing channel 22, such as... Figure 6 As shown, the axis of the flushing channel 22 is parallel to the axis of the baffle 16, and a bent section is provided at the bottom end of the flushing channel 22, which extends to the bottom end of the inner arc surface of the baffle 16.

[0060] Preferably, two flushing channels 22 are provided, and the two flushing channels 22 are symmetrically distributed with respect to the electronic endoscope mounting channel.

[0061] Furthermore, since the flushing channel 22 is completely embedded inside the baffle 16, the axis of the flushing channel 22 is parallel to the axis of the baffle 16, and the thickness of the baffle 16 is small, the cross section of the flushing channel 22 perpendicular to its extension direction is elliptical, which ensures the water injection volume.

[0062] The top of the flushing channel 22 extends to the top of the baffle 16 and connects to a connecting channel 23 within the connecting plate 17. The connecting channel 23 is elliptical and extends to the middle of the connecting plate 17. One end of the connecting channel 23 communicates with the top of the flushing channel 22, and the other end has a 90° bend 24. The 90° bend 24 is circular and extends to the side of the connecting plate 17 to form a circular interface. This interface is used to install a water injection connector, which can be installed using existing technology and will not be described in detail here. The interface is located on the side of the connecting plate 17 and will not interfere with the surgical procedure.

[0063] It is understandable that the axis of the flushing channel 22 may not be parallel to the axis of the baffle 16, and the flushing channel 22 may extend directly to the inner side of the baffle 16. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.

[0064] Through the flushing channel 22, saline solution can be injected into the surgical area to rinse the wound, cool it, and keep the tissue moist, preventing the lens from fogging or blood from clotting and obstructing the field of vision.

[0065] In this embodiment, the integral structure formed by the baffle 16 and the connecting plate 17 has a flushing channel 22, a connecting channel 23, and corresponding bending sections inside, which can be manufactured using 3D printing technology for easy processing. Existing technologies can be used for processing, and will not be described in detail here.

[0066] The electronic endoscope 21 is detachably connected within the electronic endoscope mounting channel, allowing surgeons to change the electronic endoscope to different viewing angles as needed.

[0067] Specifically, in one embodiment, the electronic endoscope 21 is fixed to the inner side of the electronic endoscope mounting channel by friction. Only when the user applies a certain external load to the electronic endoscope 21 can the electronic endoscope 21 overcome the friction to be pulled out or inserted into the electronic endoscope mounting channel. In another embodiment, two elastic clips (omitted in the figure) are provided on the top surface of the baffle 16 or the connecting plate 17. The elastic clips are located on both sides of the opening formed by the electronic endoscope mounting channel extending to the top surface of the baffle 16 and the connecting plate 17, respectively. The elastic clips can hold and fix the top of the electronic endoscope 21 by elastic force. When the electronic endoscope 21 needs to be replaced, external force is applied to pull out the electronic endoscope 21, and then a new electronic endoscope is replaced into the electronic endoscope mounting channel 21. The elastic clips clamp and fix the new electronic endoscope 21, while restricting the rotation of the electronic endoscope 21.

[0068] The method of using the open spinal electronic endoscopy system in this embodiment is as follows:

[0069] Select a baffle 16 of appropriate size according to the patient's body shape. Fix the baffle 16 to the opening ends of the first retractor 1 and the second retractor 2. During the operation, insert the two baffles 16 into the soft tissue of the patient's surgical site through the incision. The surgeon uses a retractor to move the two baffles 16 in opposite directions to expand the soft tissue and form a channel for inserting surgical instruments. Place the handle of the retractor on the patient's back. The surgeon inserts the corresponding surgical instruments into the channel formed between the two baffles 16 and uses the surgical instruments to perform the operation on the surgical site. During the operation, the angle of the baffle 16 can be adjusted by the angle adjustment mechanism to meet the operating space requirements of the surgical instruments.

[0070] The open spinal electronic endoscope system of this embodiment features two baffles 16 each equipped with an electronic endoscope 21. These two endoscopes 21 can acquire images of the surgical area from all directions, ensuring that surgical instruments do not obstruct the field of vision and facilitating surgical operations. The baffles 16 are connected to the opening end of a retractor via an angle adjustment mechanism. The angles of the two baffles 16 are adjustable, and the retractor can also adjust the expansion degree of the two baffles 16. This allows for adjustment of the space between the two baffles 16 for inserting surgical instruments, reducing limitations during instrument operation and further facilitating surgical personnel. The baffles 16 are connected to the retractor; during surgery, the retractor is placed on the patient's back, fixing the electronic endoscope 21 and allowing the surgeon to operate the surgical instruments with both hands, further enhancing surgical convenience.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
