[0002] When performing endoscopic surgery, surgeons need to flexibly adjust the angle of the endoscope to observe lesions and perform delicate procedures. However, existing endoscopic assistive devices have the following problems: Insufficient rotational freedom: Traditional devices often rely on robotic arms to provide rotational freedom, but due to the structural limitations of the robotic arms, the rotational angles in the horizontal and vertical directions are usually insufficient, and continuous 360-degree rotation around the central axis of the endoscope cannot be achieved.

[0003] Cable tangling issue: The rotation of the endoscope may cause cable tangling, which can affect the smooth progress of the operation and the lifespan of the equipment.

[0004] Complex structure and cumbersome operation: Existing devices usually require complex mechanical structures, which increases the weight of the device and the difficulty of operation, and at the same time, they are poorly adaptable to the medical environment.

[0005] Inconvenient cleaning and disassembly: In practical applications, endoscopes need to be frequently disassembled for cleaning and disinfection before being reinstalled. The disassembly and assembly process of existing auxiliary devices is relatively complicated, which increases the preparation time and difficulty of operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0022] like Figure 1 and Figure 2 As shown, a surgical aid device for endoscopy includes: a support arm, a quick-release device, a slip ring, a trigger drive device, a first motor, and a second motor.

[0023] The load-bearing arm includes a horizontal hanger and an L-shaped hanger connected by pins. The L-shaped hanger is provided with a first through hole and a second through hole.

[0024] The first and second rotating wheels are fixed on the L-shaped hanger and are connected by a belt.

[0025] The first rotating wheel is connected to the first motor via a drive shaft passing through the first through hole, and the second rotating wheel is connected to the shaft end adapter via a rotating shaft passing through the second through hole, thereby realizing the synchronous belt pulley transmission function and providing the endoscope with 360 degrees of freedom to rotate around the central axis.

[0026] The slip ring is fixed between the shaft end adapter and the rotating shaft. The electrical connection between the fixed cable part and the rotating cable part is realized through the multi-channel structure. The sliding contact surface is made of low friction material to ensure that the cable will not entangle when the endoscope is rotated.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the quick-release device includes a tray, a base, a fixing groove, a fixing cover, and a positioning groove. The base is fixed to the tray with hand-tightened screws. The positioning groove is used to position the endoscope. The fixing groove and the fixing cover are connected by a pin. The fixing groove has a protruding section that cooperates with the recessed section on the fixing cover for quick fixing and removal of the endoscope.

[0028] like Figure 6 and Figure 7 As shown, the trigger drive device includes a trigger drive ring, a trigger drive block, and a lead screw slide rail. The trigger drive block is fixed on the lead screw slide rail and is driven by a second motor connected to the lead screw slide rail, which drives the trigger drive ring to move. The drive ring is elastic, adapting to the arc-shaped movement trajectory of the endoscope trigger to ensure backlash-free operation.

[0029] During the procedure, the endoscope needs to be cleaned and disinfected. The operator can directly flip open the fixing cover to quickly remove the endoscope for cleaning. If different sizes of endoscopes need to be installed, the position of the fixing slot can be adjusted by rotating the hand-tightening screw on the fixing slot and sliding through the hole.

[0030] After cleaning, the endoscope can be quickly aligned with the fixed position on the tray via the positioning groove, and then the fixing cover can be fastened onto the fixing groove. The entire disassembly and assembly process takes only a few seconds, greatly improving efficiency.

[0031] The quick-release device makes the cleaning and reinstallation of the endoscope efficient and fast, meeting the needs of high-frequency surgical operations and significantly improving the practicality of the device.

[0032] During the operation, the first motor drives the first rotating wheel, which is then transmitted to the second rotating wheel via a belt, enabling the endoscope to rotate 360 ​​degrees continuously around its central axis, thus meeting the observation needs of complex surgical scenarios.

[0033] The second motor drives the lead screw slide rail, which in turn drives the trigger drive ring through the trigger drive block. The drive ring is elastic and works in conjunction with the endoscope trigger to ensure the precise arc movement of the trigger, thus improving the flexibility of the surgical operation.

[0034] The slip ring prevents signal interruption or equipment damage caused by cable entanglement during endoscope rotation, further ensuring the smooth progress of the surgical procedure.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
