Description

Technical Field

[0001] This utility model relates to the field of medical surgical instrument technology, specifically a UBE surgical auxiliary cavity drainage device. Background Technology

[0002] UBE surgery, short for Unilateral Dual-Channel Endoscopic Surgery, is a minimally invasive spinal technique. Its core principle involves making two small incisions of approximately 1 cm on one side of the patient's back, placing an endoscope and surgical instruments in each, and using a high-definition imaging system to magnify the surgical field for precise treatment of spinal lesions.

[0003] Obstructed water flow and blurred surgical field frequently occur during UBE surgery. For surgeons in the early stages of skill development, this unclear surgical field due to water flow issues has a significant impact on the duration and safety of the operation. Therefore, there is a need for a device that can quickly establish a space between two channels to form a relatively stable water flow channel, and that can quickly enter the surgical area during operation, reducing soft tissue obstruction and facilitating water drainage. Thus, we need a UBE surgery auxiliary cavity creation and water drainage device. Utility Model Content

[0004] The purpose of this invention is to provide a UBE surgical auxiliary cavity drainage device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UBE surgical auxiliary cavity drainage device, comprising two arm-type frames and an angle adjustment assembly. Sliding adjustment assemblies are fixedly installed on the inner sides of both arm-type frames. The two arm-type frames are hinged together in a symmetrical "U" shape on both sides of the angle adjustment assembly. Each arm-type frame includes a main body, with a sliding groove inside. A telescopic claw is movably engaged inside the sliding groove. A connecting groove is provided on the upper inner side of the main body, and the angle adjustment assembly is movably installed inside the connecting groove. The sliding adjustment assembly includes a screw movably installed in the sliding groove. A retaining ring is fixedly installed on the outside of the screw. A fixing ring is fixedly installed on the top of the retaining ring. An adjusting nut located on the top of the main body is fixedly installed on the top of the fixing ring. The telescopic claw is threadedly connected to the outside of the screw.

[0006] Preferably, a guide groove is provided on the upper part of the main body, and a locking block and a spring located inside the locking block are movably engaged inside the guide groove. The fixing ring is located on the outside of the locking block, and the locking block is movably engaged inside the fixing ring.

[0007] The beneficial effect of the above-mentioned further solution is that the locking block is inserted into the fixing ring to lock the ring, thereby fixing the screw. The locking block is maintained in the locked state by the spring force. If the telescopic claw needs to be adjusted, the locking block is manually pushed open to unlock it. After adjustment, the locking block is released, allowing it to relock under the action of the spring force.

[0008] Preferably, the fixing ring has equidistant annular grooves inside that correspond to the locking blocks.

[0009] The beneficial effects of the aforementioned further design are: the groove allows the locking block to be more stably engaged in the retaining ring, enhancing the stability of the lock. When the locking block is unlocked by external force, it can accurately slide into the corresponding groove, achieving relocking. This design not only improves the ease of operation of the device but also ensures stability and safety during the surgical procedure.

[0010] Preferably, a toothed disc is fixedly connected to the inner side of the connecting groove, and a toothed pressure nut is fixedly installed on the outer side of one of the main bodies.

[0011] The beneficial effects of the above-mentioned further scheme are as follows: the two main bodies are hinged together by bolt rods, and the toothed nut is threaded to the bolt rods. The pressure between the toothed discs is controlled by operating the tightness of the toothed nut, thereby achieving the adjustment and fixation of the angle between the two main bodies. When the angle changes, the two main bodies will change their angle accordingly and tilt artificially to adapt to the needs of the two-channel operation during the operation, avoiding obstruction between instruments. While ensuring the creation of cavity for water flow, it also leaves as much space as possible for surgical operation, ensuring the maximum clarity of the surgical field.

[0012] Preferably, the lower end of the telescopic claw is configured in an inwardly obtuse angle hook shape.

[0013] The beneficial effect of the above-mentioned further solution is that it enables the telescopic claw to pull the soft tissue structures such as fat in the channel inward and upward, thereby reducing the soft tissue between the two channels and increasing the water flow space.

[0014] Preferably, the inner side of the lower end of the telescopic claw is provided with anti-slip texture.

[0015] The beneficial effects of the above-mentioned further solutions are: the anti-slip texture enhances the friction between the telescopic claw and the soft tissue, making the traction more stable, avoiding operational errors caused by unstable traction during the operation, and further improving the safety and efficiency of the operation.

[0016] Preferably, a limiting post is provided on the lower inner side of the slide groove, and a limiting groove is provided on the outer side of the telescopic claw, with the limiting post being movably engaged with the inside of the limiting groove.

[0017] The beneficial effects of the above-mentioned further solutions are: the telescopic claw has a clear limiting point during the sliding process, which avoids excessive movement or dislocation of the telescopic claw in the groove, ensuring the stability and accuracy of the surgical operation. The cooperation between the limiting post and the limiting groove also provides a stable support point for the telescopic claw, so that when traction is applied to soft tissue, the telescopic claw can maintain a stable force and direction, further improving the smoothness and safety of the surgical operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are: a UBE surgical auxiliary cavity drainage device: By using this device, the space between the two channels can be quickly established, forming a relatively stable water flow channel; during operation, it can quickly enter the surgical area, reducing soft tissue obstruction; it can more efficiently drain soft tissue fragments and bleeding, improve surgical efficiency, reduce surgical risks, and avoid frequent water flow interruptions to the surgical process. The angle and distance between the two main bodies can be adjusted according to the needs of the operation, which can create a certain operating space for the dual channels during the operation, avoid mutual obstruction between instruments, improve flexibility, and make the subcutaneous soft tissue structure relatively fixed, preventing it from drifting with water and interfering with the surgical field.

[0023] A guide groove 15 is provided on the upper part of the main body 11. A locking block 25 and a spring 26 located inside the locking block 25 are movably engaged inside the guide groove 15. A fixing ring 23 is located on the outside of the locking block 25, and the locking block 25 is movably engaged inside the fixing ring 23.

[0024] The inner ring of the fixing ring 23 has grooves that are equidistant from each other and correspond to the locking block 25.

[0025] A limiting post 17 is provided on the lower inner side of the slide 12, and a limiting groove 18 is provided on the outer side of the telescopic claw 13. The limiting post 17 is movably engaged with the inside of the limiting groove 18.

[0026] The working principle or usage method of this embodiment is as follows: During use, the adjusting nut 24 is rotated, and the adjusting nut 24 is driven by the fixed ring 23, the retaining ring 22 and the screw 21. The rotation of the screw 21 drives the telescopic claw 13, which is threaded to the outside of it, to move up and down along the inside of the slide groove 12, thereby controlling the telescopic length. The retaining block 25 is locked into the fixed ring 23, thereby locking the screw 21. The retaining block 25 is locked by the elastic force of the spring 26. When it is necessary to adjust the telescopic claw 13, the retaining block 25 is opened and unlocked by hand. After the adjustment is completed, the retaining block 25 is released and naturally locked again under the elastic force of the spring 26. By setting the limiting post 17 in the limiting groove 18, the limiting post 17 is located inside the limiting groove 18 when the telescopic claw 13 slides, which can limit the telescopic claw 13.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a UBE surgical auxiliary cavity drainage device includes two arm-type frames 1 and an angle adjustment assembly 3. Sliding adjustment assemblies 2 are fixedly installed on the inner sides of both arm-type frames 1. The two arm-type frames 1 are hinged together in a symmetrical "U" shape on both sides of the angle adjustment assembly 3. Each arm-type frame 1 includes a main body 11, with a sliding groove 12 inside. A telescopic claw 13 is movably engaged inside the sliding groove 12. A connecting groove 14 is provided on the upper inner side of the main body 11, and the angle adjustment assembly 3 is movably installed inside the connecting groove 14. The sliding adjustment assembly 2 includes a screw 21 movably installed in the sliding groove 12. A retaining ring 22 is fixedly installed on the outside of the screw 21. A fixing ring 23 is fixedly installed on the top of the retaining ring 22. An adjusting nut 24 located on the top of the main body 11 is fixedly installed on the top of the fixing ring 23.

[0029] The lower end of the telescopic claw 13 is set in an inward obtuse angle hook shape.

[0030] The inner side of the lower end of the telescopic claw 13 is provided with anti-slip texture 16.

[0031] Furthermore, all structural edges in the aforementioned device undergo geometric blunting treatment with curvature transition to eliminate sharp angles and form continuous smooth surfaces, ensuring that all edges meet the requirements of the YY / T0149 Medical Device Surface Safety Specification, effectively preventing tissue scratches and other issues during surgery.

[0032] Working principle: The gear-shaped structure of the gear discs 31 on the inner side of the connecting grooves 14 of the two main bodies 11 is used to lock them together to ensure a tight fit. The two main bodies 11 are hinged by a bolt rod, which is connected to a toothed pressure nut 32. By rotating and adjusting the toothed pressure nut 32, the pressure between the gear discs 31 is controlled, thereby adjusting and fixing the angle between the two main bodies 11. When the angle changes, the two main bodies 11 will change their angle accordingly and tilt artificially to adapt to the needs of two-channel operation during the operation, avoiding obstruction between instruments. While ensuring the creation of cavity for water flow, it also leaves enough space for surgical operation as much as possible to ensure the maximum clarity of the surgical field.
