Description

Technical Field

[0001] The utility model belongs to the technical field of hip replacement surgery, and particularly relates to a splash-proof baffle for hip replacement surgery. Background Art

[0002] Hip replacement surgery, also known as artificial hip replacement, is a surgical method to replace the femoral head and acetabulum damaged by diseases or traumas with an artificial hip joint. The main purpose of this surgery is to remove the lesion, relieve pain, restore joint movement and the original function. The splash-proof baffle for hip replacement surgery is an auxiliary tool used during hip replacement surgery. Its main purpose is to prevent splashes such as blood and bone chips generated during the surgery from splashing onto medical staff, the surgical area or other parts of the patient, thereby ensuring surgical safety, reducing the risk of infection, and reducing the difficulty of postoperative cleaning work.

[0003] The utility model with the publication number "CN216021422U", a special transparent splash-proof baffle for joint replacement, includes: a first outer plastic metal frame, in which a first receiving seam is opened; a second outer plastic metal frame, which is located outside the first outer plastic metal frame; a micro-nano atomic film; a first hole plastic metal pressing plate, in which a slit is opened; a second hole plastic metal pressing plate, which is located behind the micro-nano atomic film. This special transparent splash-proof baffle for joint replacement is convenient for disassembly and assembly, so as to facilitate the reuse of the plastic metal frame. It can achieve the effects of not dripping with blood and anti-glare. During the surgery, it does not obstruct the doctor's vision during osteotomy surgery, can change the shape of the micro-nano atomic film according to the intraoperative situation to adapt to intraoperative operations, and avoid generating gaps after the hole plastic metal pressing plate is closed.

[0004] Although the above utility model is convenient for disassembly and assembly, thus facilitating the reuse of the plastic metal frame, can achieve the effects of not dripping with blood and anti-glare, does not obstruct the doctor's vision during osteotomy surgery during the operation, can change the shape of the micro-nano atomic film according to the intraoperative situation to adapt to intraoperative operations, and avoid generating gaps after the hole plastic metal pressing plate is closed, but due to the small size of the micro screws, higher precision and careful operation are required during disassembly. Medical staff need to operate carefully to avoid damaging the screws or the surrounding metal frame, which increases the complexity and time cost of the surgery. Moreover, during the disassembly process, if the operation is improper, the micro screws may break, deform or be lost, thereby affecting the integrity and stability of the metal frame. This will not only increase the surgical risk, but also may affect the postoperative recovery effect. At the same time, specific tools such as micro screwdrivers or wrenches are usually required to disassemble the micro screws. If these tools are lacking or not matched at the surgical site, it will further increase the difficulty and time of disassembly. Summary of the Utility Model

[0005] In view of the problems mentioned in the background art, the purpose of the present utility model is to provide a splash-proof baffle for hip replacement surgery, so as to solve the problem that due to the small size of the micro-screw, higher precision and careful operation are required during disassembly. Medical staff need to operate carefully to avoid damaging the screw or the surrounding metal frame, which increases the complexity and time cost of the surgery. Moreover, during the disassembly process, if the operation is improper, the micro-screw may break, deform or be lost, thus affecting the integrity and stability of the metal frame, not only increasing the surgical risk but also possibly affecting the postoperative recovery effect.

[0006] The above technical object of the present utility model is achieved through the following technical solutions:

[0007] A splash-proof baffle for hip replacement surgery, comprising a first metal frame. The upper end of the first metal frame is movably connected to a second metal frame. Symmetrically fixed to the bottom end of the second metal frame are connecting blocks. Inside the connecting blocks are installed fixing components. Inside the first metal frame and the second metal frame is movably connected a baffle. Symmetrically opened at one end of the baffle are through holes. Symmetrically slidably connected to both ends of the first metal frame and the second metal frame are moving seats.

[0008] The fixing components include a cavity, a return spring, a moving plate and a locking block. Inside the connecting block is opened a cavity. Symmetrically fixed to one end inside the cavity are return springs. The other ends of the return springs are fixed to a moving plate. The moving plate is slidably connected to the inside of the cavity. Fixed to the end of the moving plate away from the return spring is a locking block. The end of the locking block away from the moving plate extends out of the side end of the connecting block. The bottom end of the locking block is provided as an inclined surface. Symmetrically opened at the upper end of the second metal frame are connecting grooves. The connecting grooves are inserted into the connecting blocks. Opened at one end inside the connecting grooves is a locking groove. The other end of the locking groove penetrates the first metal frame. The locking groove is clamped with the locking block. Slidably connected inside the locking groove is an unlocking block. The end of the unlocking block away from the locking block extends out of the side end of the first metal frame. Symmetrically fixed to both ends of the locking block are limiting blocks. Symmetrically opened inside the locking groove are limiting grooves. The limiting grooves are slidably connected to the limiting blocks. Without complex steps and tools, the installation and disassembly of the baffle can be completed, making the installation and disassembly process of the baffle simpler and faster, which helps to quickly replace the baffle during the surgery, improving the surgical efficiency. Moreover, without the obstruction of small parts such as micro-screws, the baffle and its surrounding area are easier to be thoroughly cleaned and disinfected, which is beneficial to maintaining the aseptic state of the surgical environment.

[0009] As a preferred technical solution, positioning blocks are symmetrically and fixedly connected to both the upper end and the lower end of the baffle. Positioning grooves are symmetrically formed at both the inner bottom end of the first metal frame and the inner upper end of the second metal frame. The positioning grooves and the positioning blocks are inserted into each other. The design of the positioning blocks and the positioning grooves enables the baffle to be accurately installed on the metal frame, avoiding the displacement or loosening of the baffle during the operation, ensuring the accuracy and stability of the surgical operation, and contributing to improving the success rate of the operation.

[0010] As a preferred technical solution, fixing blocks are symmetrically and fixedly connected to both ends inside the first metal frame and the second metal frame. Fixing grooves are symmetrically formed at both ends of the baffle. The fixing grooves and the fixing blocks are slidably connected. The design of the fixing blocks and the fixing grooves enables the baffle to be accurately installed on the metal frame, avoiding the displacement or loosening of the baffle during the operation, ensuring the accuracy and stability of the surgical operation, and contributing to improving the success rate of the operation.

[0011] As a preferred technical solution, T-shaped grooves are symmetrically formed at both ends of the first metal frame and the second metal frame. A T-shaped block is fixedly connected to one end of the moving seat. The T-shaped block and the T-shaped groove are slidably connected. The combination of the T-shaped block and the T-shaped groove ensures the precise positioning of the cleaning head during the movement, effectively preventing the cleaning head from shifting or shaking during the movement and ensuring the accuracy of the cleaning work.

[0012] As a preferred technical solution, one end of the moving seat is movably connected to a mounting seat. A cleaning head is installed at one end of the mounting seat close to the baffle. The other end of the cleaning head is in contact with one end of the baffle. It can stop in time during the operation and remove pollutants such as blood and bone chips splashed on the baffle, reducing the cleaning time during the operation, improving the operation efficiency, eliminating the need to stop during the operation for additional cleaning work, contributing to maintaining the continuity and smoothness of the operation, and moreover, removing pollutants in time, reducing the risk of cross-infection during the operation, and ensuring the safety of patients and medical staff.

[0013] As a preferred technical solution, magnetic attraction blocks are symmetrically and fixedly connected to the end of the moving seat away from the first metal frame. Magnetic attraction grooves are symmetrically formed at the end of the mounting seat close to the baffle. The magnetic attraction grooves and the magnetic attraction blocks are magnetically connected. Medical staff can quickly install the cleaning head on the splash-proof baffle and immediately carry out the cleaning work without waiting for a complex installation process.

[0014] In summary, the main beneficial effects of the present utility model are as follows:

[0015] First, in the present utility model, the baffle is inserted into the interior of the first metal frame, such that the fixing block is in sliding connection with the fixing groove, and at the same time, the positioning block is inserted into the positioning groove. Then, the second metal frame is combined with the first metal frame, such that the connecting block is inserted into the connecting groove. During the insertion process, the extrusion force presses on the inclined surface of the locking block, causing the locking block to drive the moving plate to press against the return spring, and the return spring is compressed. At the same time, the locking block retracts into the cavity interior. When the locking block moves to the locking groove, the return spring resets, and the locking block pops out and engages with the locking groove, completing the installation of the baffle. Without complex steps and tools, the installation and disassembly of the baffle can be completed, making the installation and disassembly process of the baffle simpler and faster. This helps to quickly replace the baffle during the operation, improving the operation efficiency. Moreover, without the obstruction of small parts such as micro screws, the baffle and its surrounding area are easier to be thoroughly cleaned and disinfected, which is beneficial to maintaining the aseptic state of the operation environment;

[0016] Second, in the present utility model, the mounting seat is combined with the moving seat at one end of the first metal frame, such that the magnetic attraction block is in magnetic attraction connection with the magnetic attraction groove. At the same time, the cleaning end of the cleaning head is attached to one end of the baffle. Then, the mounting seat is pushed, causing the mounting seat to drive the moving seat to move at one end of the first metal frame and the second metal frame. At the same time, the T-shaped block at one end of the moving seat slides inside the T-shaped groove. When the mounting seat moves, it drives the cleaning head to clean one end of the baffle. After the operation is completed, the mounting seat is pulled outward, causing the magnetic attraction block to end the magnetic attraction connection with the magnetic attraction groove, completing the disassembly of the mounting seat together with the cleaning head. It can timely stop and remove pollutants such as blood and bone chips splashed onto the baffle during the operation, reducing the cleaning time during the operation, improving the operation efficiency, without the need to stop during the operation for additional cleaning work, which helps to maintain the continuity and smoothness of the operation. Moreover, timely removing pollutants reduces the risk of cross-infection during the operation, ensuring the safety of patients and medical staff. BRIEF DESCRIPTION OF THE DRAWINGS
