Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a surgical channel for a nose-orbital joint pathway. Background Art

[0002] Orbital apex tumors are rare orbital diseases, and are mostly characterized by symptoms of compression of surrounding cranial nerves, such as decreased vision, ptosis, numbness around the eyes, headache, amaurosis, pupil abnormalities, etc. Due to the insidious onset, they are often difficult to detect in the early stages and are often discovered during CT and MRI examinations due to symptoms such as dizziness and headache.

[0003] Since the orbital apex area is small and deep, and is the convergence area of ​​cranial nerves and blood vessels such as the optic nerve, oculomotor nerve, abducens nerve, and ophthalmic branch of the trigeminal nerve, and is closely adjacent to the cavernous sinus and carotid artery, surgery for orbital apex tumors is complex, difficult, and highly dangerous. Traditional surgical methods such as the deep lateral orbitotomy approach, transcranial-orbital approach, and other lateral approach surgeries not only cause greater surgical trauma, but also pose many difficulties in exposing and completely removing the tumor.

[0004] Endoscopic combined with transorbital orbital apex tumor resection surgery can not only fully expose the apex tumor and stop bleeding, but also ensure the accuracy and completeness of tumor resection. However, since the surgical technology is relatively new and requires endoscope assistance, there is still a lack of corresponding supporting surgical channels. During the operation, the only way to reach the orbital apex area is through the assistant's handheld endoscope to guide the lighting and separate the orbital fat and muscle tissue through traditional surgical instruments such as brain pressure plates. The process is relatively complicated, with high labor costs and a high degree of dependence on the assistant's experience. Summary of the invention

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The present invention provides the following four technical solutions:

[0047] Figure 1-Figure 4 A first embodiment is shown: a surgical channel for a nose-orbital joint approach, comprising:

[0048] The channel main frame 1 is worn and installed at the nose socket position, and the channel main frame 1 is an inverted eye-shaped structure;

[0049] A transverse slideway 2 is provided, with one set and both ends being slidably connected to the upper and lower sections of the channel main frame 1;

[0050] The longitudinal slideway 3 is provided in two groups and slides longitudinally between two vertical sections on the left side or two vertical sections on the right side of the channel main frame 1;

[0051] A fixed pan / tilt platform 4 is slidably arranged on the front side of one of the two vertical sections in the middle of the longitudinal slideway 3 and is used for installing an endoscope or a suction device;

[0052] There are three instrument fixing platforms 5 which are respectively slidably arranged on the transverse slideway 2 and the longitudinal slideway 3 . The instrument fixing platforms 5 are used to fix the orbital pressure plate 6 or the extraocular muscle pulling structure 7 .

[0053] T-shaped slides are arranged inside the channel main frame 1, the transverse slide 2 and the longitudinal slide 3. The transverse slide 2 is slidably connected to the T-shaped slide through the first sliding blocks 21 on the rear sides of both ends. The longitudinal slide 3, the fixed pan / tilt head 4 and the instrument fixing platform 5 are slidably connected to the T-shaped slide through the second sliding blocks 31 on the rear sides of both ends. The transverse slide 2 is located in front of the longitudinal slide 3, and damping sliding is performed between the first sliding block 21, the second sliding block 31 and the T-shaped slide.

[0054] The fixed platform 4 includes a first substrate 41 and a fixing seat 42 arranged thereon. An endoscope or a suction device is tightened on the fixing seat 42 by bolts, and lighting and other instruments can also be fixed.

[0055] The instrument fixing platform 5 includes a second base plate 51 and an inclined platform 52 arranged thereon. A pair of positioning plates 53 are arranged on the side of the inclined platform 52. The fixed orbital pressure plate 6 or the extraocular muscle pulling structure 7 is tightened to the inner side of the positioning plate 53 through the bolts on the positioning plate 53.

[0056] By setting a slide and a corresponding fixing structure, this technical solution can fix structures such as endoscope guidance and lighting during endoscopic combined transorbital orbital apex tumor resection surgery, thereby providing the surgeon with a clear and stable surgical field of view and avoiding orbital fat, extraocular muscles and other tissues from obstructing the tumor; and does not require an assistant to hold tools for assistance, does not rely on the assistant's experience and surgical skills, and is stable and reliable; can effectively avoid damage to important intraorbital structures such as the optic nerve, and increases the safety and efficiency of the surgery; at the same time, ophthalmic surgery can be performed on both sides of the inverted eye-shaped channel main frame 1, and nasal surgery can be performed in the middle, thus providing a dual-camera synchronous field of view, making the surgical cooperation between nasal and ophthalmic surgeries more efficient and safer.

[0057] Figure 5-Figure 7 A second embodiment is shown, which mainly differs from the first embodiment in that the second sliding block 31 is a circular structure, so that the intersection of the second sliding block 31 and the T-shaped slide groove can slide smoothly, and the first sliding block 21 is detachably connected to the transverse slide 2 through a disassembly structure.

[0058] The disassembly structure is a long stud 22 , which passes through the transverse slideway 2 and is threadedly connected to the first sliding block 21 .

[0059] The disassembly structure includes a plug post 23 fixedly connected to the surface of the first sliding block 21, the front end of the plug post 23 slides through the first sliding block 21 and is rotatably connected to a lever 24, and the end of the lever 24 connected to the plug post 23 is set to an arc surface; metal springs 25 are fixed to the outside of both ends of the transverse slide 2, and the metal springs 25 are C-shaped. The opening of the metal spring 25 is located on the inner side of the T-shaped slide groove of the transverse slide 2, and the spacing between the openings is smaller than the diameter of the lever 24; after the lever 24 is lifted to be coaxial with the plug post 23, the plug post 23 and the lever 24 can be pulled out of the transverse slide 2 together, and after the lever 24 is pushed to be perpendicular to the plug post 23 and is stuck by the metal spring 25, the transverse slide 2 can be locked.

[0060] The circular structural design of the second sliding block 31 allows the longitudinal slide 3 and the instrument fixing platform 5 to be directly switched between the left and right eye positions on the channel main frame 1. When switching, only the transverse slide 2 needs to be disassembled without affecting the movement of the longitudinal slide 3 and the instrument fixing platform 5. The transverse slide 2 provides two types of disassembly structures, which are connected by long studs 22 and have a certain locking function. The metal spring 25 is used in conjunction with the lever 24, so that disassembly and locking can be achieved with a simple push, which is easy to use.

[0061] Figure 8-Figure 9The third embodiment is shown, which is mainly different from the first embodiment in that: the orbital pressure plate 6 and the extraocular muscle traction structure 7 both include a fixing handle 61, the fixing handle 61 has a long groove 62 for bolt positioning and fixing, one end of the fixing handle 61 of the orbital pressure plate 6 is fixedly connected to an arc-shaped pressing piece 63, and the arc-shaped pressing piece 63 has a V-shaped notch 64;

[0062] The tip of the orbital pressure plate 6 adopts a narrowed and bifurcated structural design. The narrowed design adapts to the relatively narrow structural characteristics of the orbital apex, and the bifurcated groove design at the tip can protect the central optic nerve from compression and reduce the risk of injury. The handle part is hollowed out to facilitate fixing on the bolts of the instrument fixing platform 5.

[0063] One end of the fixed handle 61 of the extraocular muscle pulling structure 7 is fixedly connected with a thin sheet 71 , and the bottom of the thin sheet 71 is provided with a barb 72 for pulling the extraocular muscles.

[0064] The tip of the extraocular muscle pulling structure 7 adopts a narrowed structural design, which adapts to the relatively narrow structural characteristics of the orbital apex, reduces the risk of orbital apex structural damage, and the claw-shaped design of the tip can better pull the extraocular muscles, mainly the medial rectus and inferior rectus muscles, better expose the orbital apex tumor, and avoid complications caused by blind operation. The handle part is hollowed out, which is convenient for fixing on the bolts of the instrument fixing platform 5.

[0065] Figure 1-Figure 2 A fourth embodiment is shown, which mainly differs from the first embodiment in that the two middle vertical sections of the channel main frame 1 are placed on both sides of the bridge of the nose, and the rear side of the channel main frame 1 is located at the four outer corners of the two vertical sections and is rotatably provided with rotation bars 8. The rotation bar 8 is designed to rotate and can adapt to the angle of the facial curvature, and a soft rubber strip 81 is fixedly connected to the rear side of the rotation bar 8.

[0066] Buckles 9 are provided at both corners on one side of the channel main frame 1, and soft straps 10 are connected to both corners on the other side of the channel main frame 1. The cross-section of the main part of the soft strap 10 is a bead chain shape, so that the soft strap 10 is clamped by the buckle 9 after passing through the buckle 9.

[0067] By providing the rotating bar 8 with the soft rubber strip 81, it is soft and comfortable to press on the face when worn, and will not cause a hard pressure feeling. The cooperation between the soft strap 10 and the buckle 9 can not only simply and conveniently adjust the tightness of wearing, but the structure of the soft strap 10 itself can also achieve the effect of airbag cushioning, and the overall wearing is more comfortable.

[0068] The surgical channel is made of stainless steel by default, but can also be made of materials other than stainless steel. The coupling and connection between the components can adopt other connection methods besides sliding slots. The appearance size of each component can be adjusted according to the actual age, gender and range of the patient, and is not limited to the form described in the patent.

[0069] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0070] When in use, first wear the channel main frame 1 on the patient's face, wrap the soft strap 10 around the head and pass it through the buckle 9 and then tighten it, and the buckle 9 can lock the soft strap 10 after releasing it;

[0071] The required extraocular muscle traction structure 7 and orbital pressure plate 6 and other structures are clamped on the inner side of the instrument fixing platform 5. After adjusting the extraocular muscle traction structure 7 and orbital pressure plate 6, tighten the bolts to fix them. The required endoscope, suction device and other structures are fixed on the fixed pan-tilt platform 4 with bolts, and then the surgical operation can be started.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
