Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a rotatable surgical device. Background Technology

[0002] With the rapid development of minimally invasive surgical techniques, endoscopic surgery has been widely used in urology, gynecology, and general surgery due to its advantages such as minimal trauma, rapid recovery, and fewer complications. In various cavity or body cavity surgeries, instruments are typically introduced into the body through pre-placed sheaths (such as urethral sheaths, laparoscopic trocars, or natural orifice surgical channels) for diagnostic and therapeutic procedures. To facilitate multi-angle manipulation during surgery, an external operating platform is often set up to support and guide the insertion and exit of instruments.

[0003] However, most operating platforms in existing technologies are fixed structures. Once the sheath is fixed inside the patient's body, the position and orientation of the operating platform are also fixed, resulting in a limited range of motion for the instruments. When it is necessary to adjust the angle of instrument entry or the direction of observation, it is often necessary to repeatedly adjust the position of the sheath, or even re-puncture or re-insert the cannula. This not only increases the operation time but may also cause secondary damage to the patient's tissues, affecting the safety and efficiency of the operation. Utility Model Content

[0023] Reference Figures 1 to 7 , refer to Figures 1 to 7 A rotatable surgical device includes: an operating platform 100 having a through hole for inserting operating instruments; Locking element 110 is used to secure the sheath to the human body. The rotating assembly includes an upper rotating ring 120 and a lower rotating ring 130. The upper rotating ring 120 is disposed at the bottom of the operating platform 100, and the lower rotating ring 130 is disposed at the top of the locking member 110. The operating platform 100 and the locking component 110 are connected by a rotating assembly to achieve relative rotation.

[0024] A rotating assembly is constructed by setting an upper rotating ring 120 at the bottom of the operating platform 100 and a lower rotating ring 130 at the top of the locking member 110, enabling a relative rotational connection between the operating platform 100 and the locking member 110. During surgery, the entry angle and operating direction of the instruments on the operating platform 100 can be flexibly changed without adjusting or moving the sheath already fixed to the patient, significantly improving the freedom and adaptability of surgical operations. The rotating assembly connects the operating platform 100 and the locking member 110, maintaining structural independence and modularity while achieving functional linkage. It facilitates disassembly, sterilization, and reuse, improving the clinical applicability and efficiency of the device. This rotating connection structure can stably maintain the orientation of the operating platform 100 during surgery, while allowing the surgeon to manually adjust its rotation position as needed, meeting the needs of multi-angle and multi-directional surgeries, especially suitable for minimally invasive surgical scenarios with limited space or requiring precise manipulation. The overall structural design is reasonable, assembly is simple, and operation is intuitive, helping to shorten surgical preparation time, reduce the risk of tissue damage caused by frequent changes or adjustments to instrument channels, and improve surgical safety and patient comfort.

[0025] The lower rotating ring 130 has a hook 170 at its top, and the upper rotating ring 120 has a locking groove 150 on its side wall. The hook 170 can be rotatably engaged in the locking groove 150. When the operating platform 100 is assembled with the locking member 110, the lower rotating ring 130 at the top of the locking member 110 is first aligned with the upper rotating ring 120 at the bottom of the operating platform 100. The hook 170 at the top of the lower rotating ring 130 slides into the corresponding locking groove 150 on the side wall of the upper rotating ring 120 along the guide path (such as the guide slope 160 or the opening inlet area) of the side wall of the upper rotating ring 120. As the assembly progresses, the hook 170, under elastic or guiding action, passes over the local structure of the upper rotating ring 120 (such as the edge of the groove) and is finally fully embedded in the locking groove 150, forming an axial limiting connection. At this point, the upper rotating ring 120 and the lower rotating ring 130 are circumferentially connected by the engagement of the hook 170 and the locking groove 150, but this restricts their axial disengagement. During the operation, the operating platform 100 can rotate relative to the hook 170 engaged within the upper rotating ring 120, thereby adjusting the circumferential angle of the operating instrument passing through the through hole. This rotational movement is smooth and controllable, and the engagement structure of the hook 170 and the locking groove 150 effectively maintains connection stability and prevents accidental loosening in the absence of forced disassembly.

[0026] The engagement of the hook 170 and the locking groove 150 creates a mechanical connection structure that allows relative rotation while preventing axial separation, ensuring that the operating platform 100 will not fall off during rotation and improving the safety and reliability of the device. The locking structure is integrated between the upper and lower rotating rings 130, without occupying additional space, making it suitable for minimally invasive surgeries where instrument size is critical, and contributing to the overall miniaturization and weight reduction of the device.

[0027] The bottom of the upper rotating ring 120 is provided with a guide slope 160, which is used to guide the upper rotating ring 120 to align with the lower rotating ring 130 during installation. During installation, when the operating platform 100 moves downwards towards the locking member 110, the upper rotating ring 120 at its bottom begins to contact the lower rotating ring 130. Because the bottom of the upper rotating ring 120 is provided with the guide slope 160, this slope first contacts the top edge of the lower rotating ring 130. The guide slope 160 gradually decreases radially from the inside to the outside, forming a trumpet-shaped guide structure. As the assembly force continues to be applied, the guide slope 160 decomposes the force into axial pressure and radial adjustment force, pushing the upper rotating ring 120 to automatically align with the center, or causing the locking hook 170 and other mating structures of the lower rotating ring 130 to smoothly slide into the locking groove 150 on the side wall of the upper rotating ring 120. This guiding function effectively compensates for any initial positional deviations that may occur during assembly, ensuring that the upper and lower rotating rings 130 can quickly and accurately complete alignment and engagement, avoiding assembly difficulties or structural damage caused by misalignment. By smoothing the guide contact surface, wear or plastic deformation caused by hard impacts or misalignment compression of the edges of the upper and lower rotating rings 130 is avoided, extending the service life of the device, especially protecting plastic or precision-machined parts.

[0028] The upper rotating ring 120 is provided with a plurality of first anti-slip parts 140, which are spaced apart on the end face of the upper rotating ring 120 that abuts against the operating platform 100. The lower rotating ring 130 is provided with a plurality of second anti-slip parts 190, which are spaced apart on the end face of the lower rotating ring that abuts against the locking member 110. The upper rotating ring 120 and the operating platform 100, and the lower rotating ring 130 and the locking member 110 are fixedly connected by end face abutment. When the operating platform 100 is subjected to external force (such as insertion of operating instruments, intraoperative angle adjustment, or traction), there may be a tendency for relative sliding between the upper rotating ring 120 and the operating platform 100. Similarly, the lower rotating ring 130 and the locking member 110 may also undergo slight displacement due to rotation operation or external disturbance. At this time, the multiple first anti-slip parts 140 provided on the contact end face of the upper rotating ring 120 and the operating platform 100, and the multiple second anti-slip parts 190 provided on the contact end face of the lower rotating ring 130 and the locking member 110, significantly increase the friction of the contact interface through their surface protrusions, textures, or rough structures. These anti-slip parts are distributed circumferentially or in an array, forming a local high-stress contact area with the corresponding component surface after assembly and clamping, effectively suppressing relative sliding. Especially during rotation operation, although the upper and lower rotating rings 130 can rotate relative to each other, the upper rotating ring 120 and the operating platform 100, and the lower rotating ring 130 and the locking member 110 remain fixed. The presence of the anti-slip parts ensures this functional separation of "internal fixation and external rotation," preventing loosening of the connection due to vibration or operating force, thereby maintaining the stability of the entire device structure.

[0029] The first anti-slip part 140 and the second anti-slip part 190 respectively enhance the end-face friction between the upper rotating ring 120 and the operating platform 100, and between the lower rotating ring 130 and the locking member 110, effectively preventing relative rotation or axial slippage caused by external forces during use, and improving connection reliability. If the rotating assembly becomes loose between itself and the operating platform 100 or the locking member 110, it may lead to unstable rotation, inaccurate positioning, or even instrument displacement. The design of the anti-slip part avoids such problems from the source, ensuring stable operation of the device during long-term surgery.

[0030] The lower rotating ring 130 has several clearance portions on its sidewall, which divide the sidewall of the lower rotating ring 130 into multiple circumferentially distributed arc-shaped segments 180. The lower rotating ring 130 is used to connect the locking member 110 and the upper rotating ring 120. Its sidewall has several axially extending clearance portions (such as slits or notches), which are evenly distributed circumferentially, dividing the outer sidewall of the lower rotating ring 130 into multiple independent arc-shaped segments 180.

[0031] When the upper rotating ring 120 is assembled onto the top of the lower rotating ring 130, each arc-shaped segment 180 possesses a certain radial elastic deformation capacity due to the presence of clearance portions. Under external force, the arc-shaped segments 180 can contract inward or expand outward, thus adapting to the interference fit dimensions of the annular mounting groove. As assembly progresses, the arc-shaped segments 180 gradually enter the predetermined position of the mounting groove and, relying on the elastic recovery force of the material, tightly adhere to the groove wall, achieving a secure connection. During rotational engagement with the upper rotating ring 120, the gaps between the arc-shaped segments 180 (i.e., clearance portions) can also accommodate localized stress, reducing structural fatigue caused by torsional loads and ensuring smooth rotation and stable connection. After elastic recovery, multiple arc-shaped segments 180 form multi-point or surface contacts with the inner wall of the mounting groove, increasing friction and engagement force, effectively preventing axial detachment or circumferential loosening of the lower rotating ring 130 during use, and improving the overall structural stability.

[0032] The top of the locking member 110 forms an annular mounting groove, and the lower rotating ring 130 is engaged within the annular mounting groove. In the rotatable surgical device of the present invention, the locking member 110 is used to fix a sheath installed on a human body part, and its top is provided with a specially designed annular mounting groove. The annular mounting groove is a groove structure that is continuously or intermittently distributed along the circumference and is located on the upper end face or the top area of ​​the side wall of the locking member 110.

[0033] During assembly, the lower rotating ring 130 is aligned with the annular mounting groove from above and pressed downwards with axial pressure. Since the inner diameter of the annular mounting groove is slightly smaller than the outer diameter of the lower rotating ring 130 (or through a flexible arc segment 180), the lower rotating ring 130 undergoes slight radial compression during insertion, and then, under the action of elastic restoring force, it snaps into the groove, achieving axial limiting and circumferential fixed connection. This snap-fit ​​structure can be an interference fit, a flexible snap-fit, or a combination of fixing methods. After assembly, the lower rotating ring 130 is stably fixed in the annular mounting groove, serving as the lower support unit of the rotating assembly. It cooperates with the upper rotating ring 120 located at the bottom of the operating platform 100 to jointly realize the free rotation function of the operating platform 100 relative to the locking member 110.

[0034] The annular mounting groove provides a clear installation position and limiting boundary for the lower rotating ring 130, ensuring effective constraint in both the axial and radial directions. This prevents loosening, detachment, or displacement during use, significantly improving the overall connection stability of the device. The annular mounting groove structure allows the lower rotating ring 130 to be installed quickly and accurately, supporting a split design between the operating platform 100 and the locking element 110. This facilitates preoperative assembly, postoperative disassembly, and component replacement, enhancing the flexibility of clinical use.

[0035] The annular mounting groove has a variable cross-section structure with uneven thickness. The lower rotating ring 130 is fixed within the annular mounting groove through a combination of localized thickening and narrowing. This structure incorporates locally thickened and narrowed areas at different locations within the groove, creating an asymmetrical or periodically varying cross-sectional profile. The variable cross-section structure applies greater radial clamping force to the lower rotating ring 130 through the locally thickened areas, forming "critical anchor points" that effectively prevent loosening during surgery due to vibration, torsion, or axial loads, significantly improving the safety and long-term stability of the connection.

[0036] The outer wall of the operating platform 100 is provided with anti-slip textures. The operating platform 100 is used to support and guide surgical instruments inserted through its through-holes. During surgery, medical personnel need to hold the outer wall of the operating platform 100 to adjust its position or perform rotational operations. Because the surgical environment often contains liquids (such as irrigation fluid, blood) or the operator wears gloves, reducing hand friction, slippage is likely. Therefore, anti-slip textures, such as annular grooves, raised ridges, diagonal stripes, or grid patterns, are provided on the outer wall of the operating platform 100. When the operator holds it, the fingers or glove form a mechanical engagement with the anti-slip textures, increasing the coefficient of friction of the contact surface and effectively preventing the device from slipping in the hand or rotating uncontrollably.

[0037] The anti-slip texture increases the friction on the outer surface of the operating platform 100, effectively preventing slippage during surgery caused by sweaty hands, liquid lubrication, or wearing gloves. This ensures that medical staff can hold the device firmly and operate it precisely. A stable grip helps reduce accidental displacement or rotation, preventing instruments from accidentally injuring tissue or deviating from the target area, thus improving the safety and precision of the surgical procedure.

[0038] The upper rotating ring 120 and the operating platform 100 are connected by an interference fit, as are the lower rotating ring 130 and the locking member 110. During assembly, axial pressure is applied to press the upper rotating ring 120 into the mounting position of the operating platform 100, or the lower rotating ring 130 into the annular mounting groove of the locking member 110. During the pressing process, the mating surfaces undergo slight elastic deformation. After assembly, the elastic recovery force of the material generates continuous radial pressure between the contact surfaces, forming a tight, gapless connection. The interference fit generates continuous friction and mechanical interlocking force between the contact surfaces, effectively resisting vibration, torsion, and axial impact caused by instrument operation during surgery, preventing relative sliding or loosening between the rotating ring and the main body components, and ensuring stable operation of the device.

[0039] The inner wall of the locking member 110 is provided with a guide wall 200. When the lower rotating ring 130 is installed on the locking member 110, it presses the bottom of the operating platform 100 against the guide wall 200. The locking member 110 is used to fix the sheath installed on the human body, and its inner wall is provided with an inwardly protruding guide wall 200 (which can be an annular boss, a stepped structure, or a partial retaining edge). When the lower rotating ring 130 is assembled into the annular mounting groove at the top of the locking member 110, the operating platform 100 is pressed downward along with the upper rotating ring 120, and its bottom finally presses against the upper surface of the guide wall 200 after assembly. The guide wall 200 plays a dual role in the assembly process: on the one hand, its inner diameter edge can serve as a guide surface to help the operating platform 100 or the upper rotating ring 120 to be aligned and smoothly enter the interior of the locking member 110; on the other hand, after assembly, the guide wall 200 forms an axial load-bearing step, directly bearing the axial pressure from the operating platform 100. Through this structure, the weight of the operating platform 100 and the axial load generated by the surgical instruments passing through its through-holes are all transferred through the bottom of the platform to the guide wall 200, then borne by the locking member 110 and finally transferred to the fixed sheath. Thus, the guide wall 200 becomes a key load-bearing structure supporting the entire operating platform 100 and its load. The large contact area between the guide wall 200 and the bottom of the operating platform 100 forms a stable support interface, effectively dispersing local stress, preventing structural deformation or damage due to point loads or off-center loads, and improving the overall rigidity of the device.
