Detailed Description
Hereinafter, the bone foam protective shield in the artificial knee joint replacement of the present application will be described in detail with reference to the accompanying drawings.
The application discloses bone foam shield in artificial knee joint replacement art, it includes: a bed combining part 10, a longitudinal support part 20, a transverse support part 30 and a screen body 40.
The bed engaging portion 10 includes a first U-shaped clamp 11, a first tube 12. The first U-shaped clamp 11 includes a first side wall and a second side wall; a downward first opening is formed between the first side wall and the second side wall, a through first threaded hole is formed in the first side wall of the first U-shaped clamping piece 11, and a first bolt 13 is installed in the first threaded hole; the first bolt 13 abuts against a cross beam of the operating bed inserted in the first opening of the first U-shaped clamp 11, thereby clamping the cross beam between the first bolt 13 and the second side wall; the first tubular body 12 is formed on the first side wall extending longitudinally; a second threaded hole which is communicated with the first pipe body 12 is formed on the first pipe body; the second threaded hole has a second bolt 14 mounted therein.
The longitudinal support portion 20 includes a vertical rod 21 extending longitudinally and a cylindrical second tube 22 formed transversely at an upper portion of the vertical rod 21; a third threaded hole is formed in the second tube 22; a third bolt 23 is arranged in the third threaded hole; the lower end of the upright 21 is inserted into the first pipe body 12, and the end of the second bolt 14 abuts against the peripheral surface of the upright 21, thereby fixing the upright 21 in the first pipe body 12.
The lateral support 30 includes a cylindrical first cross bar 31; a first end of the first cross bar 31 is formed with a second U-shaped clamp 32; the second U-shaped clamp 32 includes a third side wall and a fourth side wall; a second opening is formed between the third side wall and the fourth side wall; a through fourth threaded hole is formed in the third side wall of the second U-shaped clamping piece 32, and a fourth bolt 33 is installed in the fourth threaded hole; the second end of the first rail 31 is inserted into the second pipe body 22, and the end of the third bolt 23 abuts against the circumferential surface of the first rail 31, thereby fixing the first rail 31 in the second pipe body 22.
The screen body 40 is made of a transparent plastic plate, and is bent at the middle part to form two parts, wherein the part close to the operator forms a first screen body 41, and the part far away from the operator forms a second screen body 42; the lower part of the first screen body forms a first notch 43, and the first notch 43 is formed in the middle position of the first screen body 41, so that an operator can penetrate the screen body with an operation tool to reach an operation position. On both sides of the first notch 43, second notches 44 are formed, respectively. The second notch 44 is located above the first notch 43; the side portion of the screen body 40 is inserted into the second opening of the second U-shaped clamp 32, and is clamped by the end portion of the fourth bolt 33 and the third side wall to be fixed in the second opening.
The second notch 44 is opened at a portion where the first screen body 41 and the second screen body 42 are connected.
For each second notch 44, a first portion thereof is formed on the first screen body 41 and a second portion thereof is formed on the second screen body 42.
When the device is used, the whole device is fixed on a cross beam on the side of an operation by operating a first bolt; then, according to actual need, the screen body is adjusted to a proper height by operating the second bolt, and the screen body is fixed at a proper angle by operating the third bolt to rotate, so that the bending of the knee of the patient is met to the maximum extent. The tool of the surgeon passes through the first notch to reach the surgical site of the patient for cutting; the drag hook can pass through the second gaps on the two sides of the screen body to reach the preset part of the bottom knee, so that the tissue at the knee is opened to expose the part of the bone to be cut. In the operation process, the bone foam under cutting is basically blocked by the screen body after splashing, so that the splashing is greatly reduced, and the problem that the operation area is polluted due to the splashing is avoided as much as possible.
