Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a novel protective plate used in joint replacement surgery. Background Art

[0002] Joint replacement surgery is a surgical procedure that restores joint function by replacing diseased or damaged joint parts. The most common joint replacement surgeries include artificial hip replacement and artificial knee replacement. During hip replacement surgery, the doctor will enter the hip joint through a surgical incision and remove damaged joint tissue, such as damaged articular cartilage and bone. Then, the doctor will implant artificial hip joint parts made of special metal and plastic materials into the bone to restore the function and movement of the joint.

[0003] When operating on damaged joint tissue, bone fragments are likely to splash and rebound into the surgical field, causing contamination of the surgical field. Disposable protective glasses are easy to fall off when worn, and it is heavy for people who wear glasses to wear an extra pair of glasses. When bone fragments or blood splashes on the glasses, it is easy to blur the vision and affect the surgeon's operation.

[0004] Therefore, it is necessary to provide a new type of protective plate for joint replacement surgery to solve the above technical problems. Utility Model Content

[0005] The utility model provides a novel protective plate for joint replacement surgery, which solves the problem that bone fragments are easily splashed and rebounded to the surgical field during the operation of damaged joint tissue, thus causing surgical field contamination.

[0006] In order to solve the above technical problems, the utility model provides a novel protective plate for joint replacement surgery, comprising a protective plate, a mounting block is fixed on the protective plate by screws, and a hydraulic rod is fixed at the bottom of the mounting block;

[0007] Slide blocks are slidably arranged on both sides of the protective plate, a connecting rod is fixed between the two slide blocks and at the top of the protective plate, a fixing rod is fixed between the two slide blocks and at the bottom of the protective plate, a scraper is fixed on the top of the fixing rod, and the top of the scraper contacts the bottom of the protective plate.

[0008] Preferably, a handle is fixed on the connecting rod.

[0009] Preferably, the number of the hydraulic rods is four, and a mounting foot is fixed to the bottom end of the hydraulic rod, and a mounting hole is provided on the mounting foot.

[0010] Preferably, the sliding block is provided with a sliding groove matched with the protective plate.

[0011] Preferably, the protective plate is made of transparent plastic material.

[0012] Preferably, the scraper is made of rubber.

[0013] Compared with the related art, the protective plate in the new joint replacement surgery provided by the utility model has the following beneficial effects:

[0014] The utility model provides a novel protective plate for joint replacement surgery, which is placed and fixed by a mounting foot at the bottom end of a hydraulic rod. The handle is pulled to drive a slider to move through a connecting rod, and the slider drives a scraper to move through a fixing rod, so that the scraper can scrape off bone fragments and tissue splashed on the protective plate, thereby ensuring the transparency of the protective plate and the surgical field, solving the problem that bone fragments are easily splashed and rebounded to the surgical field when damaged joint tissue is being treated, causing surgical field contamination, and improving the surgical efficiency of the surgeon. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Numbers in the figure: 1, protective plate, 2, mounting block, 3, hydraulic rod, 4, slider, 5, connecting rod, 6, fixing rod, 7, scraper, 8, handle, 9, mounting foot, 10, mounting hole. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1-2 As shown, a novel protective plate for joint replacement surgery includes a protective plate 1, which is made of transparent plastic material, so that it is convenient to observe through the protective plate 1, can be reused, and can be repeatedly sterilized and disinfected. A mounting block 2 is fixed on the protective plate 1 by screws, so that the protective plate 1 can be easily disassembled and installed. A hydraulic rod 3 is fixed at the bottom of the mounting block 2. The hydraulic rod 3 is started to adjust the protective plate 1 to a suitable height. There are four hydraulic rods 3, and a mounting foot 9 is fixed at the bottom end of the hydraulic rod 3. The mounting foot 9 is provided with a mounting hole 10. When in use, the protective plate 1 is placed on the top of the surgical site of the patient, and is placed and fixed by the mounting foot 9 at the bottom end of the hydraulic rod 3. The mounting hole 10 can be reinforced by screws.

[0020] Slide blocks 4 are slidably provided on both sides of the protective plate 1 of the utility model. The slide blocks 4 are provided with sliding grooves adapted to the protective plate 1 to play a role of limiting. A connecting rod 5 is fixed between the two slide blocks 4 and at the top of the protective plate 1. A handle 8 is fixed on the connecting rod 5. A fixing rod 6 is fixed between the two slide blocks 4 and at the bottom of the protective plate 1. A scraper 7 is fixed on the top of the fixing rod 6. The scraper 7 is made of rubber. The top of the scraper 7 contacts with the bottom of the protective plate 1. Pull the handle 8 to move the slide block 4 through the connecting rod 5. The slide block 4 drives the scraper 7 to move through the fixing rod 6, so that the scraper 7 scrapes off the bone fragments and tissues splashed on the protective plate 1 to ensure the transparency of the protective plate 1 and the surgical field of view.

[0021] The working principle of the new type of protective plate in joint replacement surgery provided by the utility model is as follows: when in use, the protective plate 1 is placed on the top of the patient's surgical site, and is placed and fixed by the mounting foot 9 at the bottom end of the hydraulic rod 3, and the hydraulic rod 3 is started to adjust the protective plate 1 to a suitable height. The surgeon's hands perform surgery on the affected area at the bottom of the protective plate 1 and observe through the protective plate 1. When bone fragments and tissues splash onto the protective plate 1, the handle 8 is pulled to drive the slider 4 to move through the connecting rod 5, and the slider 4 drives the scraper 7 to move through the fixed rod 6, so that the scraper 7 scrapes the bone fragments and tissues splashed on the protective plate 1 to ensure the transparency of the protective plate 1 and the surgical field of view. The protective plate 1 can be used by multiple people for protection, can be reused, and repeatedly sterilized and disinfected. After sterilization, it can be taken to the operating table for use to prevent blood and bone fragments from splashing.

[0022] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
