Description

An orthopedic periosteal peeler

technical field

The utility model relates to the technical field of orthopedic surgical instruments, in particular to an orthopedic periosteum stripper.

Background technique

Periosteal peeler is one of the most commonly used orthopedic instruments in orthopedic surgery. During orthopedic surgery, it is necessary to partially peel off the periosteum at both ends of the fracture, and sometimes extensive periosteal peeling is often performed to push the muscle tissue away to avoid its occlusion. The operative field of view is beneficial to reveal the fracture site, facilitate the reduction of the fracture under direct vision, and facilitate the placement and fixation of internal fixators (plates, etc.).

The existing patent (publication number: CN201692005U) proposes a periosteal peeler, which includes a peeler handle, a peeler body, and a peeler head. The front end of the peeler head has a front-end cutting edge, and the left side of the peeler head is There is a left edge and the right edge of the stripper head has a right edge.

The above-mentioned periosteal stripper has the following disadvantages when used:

As the pace of life and work changes, some working groups who have to sit and stand for a long time, maintain the same posture for a long time or have an incorrect posture and use a certain joint repeatedly, are prone to joint lesions and bone spurs. Bone spurs and other diseases have become common clinically. Diseases and frequently-occurring diseases, the treatment methods are mostly surgical treatment. During the operation, the periosteum is separated from the bone in the lesion area with a periosteum separator, and then the bone spur is flattened with a bone rasp. The function of the periosteum, but it does not have the function of facilitating the separation of the periosteum. Because the angle between the periosteum and the bone is small, the visual field is small, which is inconvenient for subsequent operations. The function of filing the bone spurs on the bone. When the bone spurs on the bone compress the surrounding nerves, tendons or other structures, it will cause symptoms such as pain, numbness, swelling, limited joint movement, etc., and then affect the normal life of the patient. Therefore, The periosteal stripper has great limitations in the use process.

To this end, we propose an orthopedic periosteal peeler to solve the above problems.

Detailed ways

Embodiment 1, as shown in Figures 1-5, an orthopedic periosteal peeler, including a handle 1 and a file plate 3, a through groove 2 is formed through the top of the handle 1, and an adjustment mechanism is arranged inside the through groove 2, and the file The plate 3 is installed inside the through groove 2 through the adjustment mechanism. The bottom of the file plate 3 is provided with a plurality of file peaks 4, and the interior of the through groove 2 is provided with a separation mechanism. The adjustment mechanism includes a limit plate 5. The inner wall of the slot 2 is connected, the top of the limit plate 5 is inserted with an insertion rod 7, the top of the insertion rod 7 is provided with a contact plate 6, the bottom end of the insertion rod 7 is connected with the top of the file plate 3, and the outside of the insertion rod 7 A first compression spring 8 is sleeved, two ends of the first compression spring 8 are respectively connected to the limit plate 5 and the contact plate 6, and both ends of the file plate 3 are embedded with a plurality of balls 17. By arranging the balls 17, the reduction of The friction force between the through groove 2 and the file plate 3 is reduced, so that the sliding of the file plate 3 in the through groove 2 is smoother, thus reducing the output of manpower. The insert rod 7 drives the file plate 3 to slide down in the through groove 2 and causes the file peak 4 to protrude from the through groove 2. At this time, the handle 1 is moved, thereby facilitating the medical staff to use the file peak 4 to file the bone at the patient's lesion site. It can effectively solve the problem of bone spurs compressing the spinal cord or nerves.

Embodiment 2, on the basis of Embodiment 1, the separation mechanism includes an installation slot 9 and a strong permanent magnet 12, the installation slot 9 is opened on the inner side wall of the through slot 2, and the inner wall of the installation slot 9 is rotatably connected with a rotating rod 10, which is rotated. The outer wall of the rod 10 is rotatably connected with the periosteum separation plate 11, the strong permanent magnet 12 and the limit plate 5 are magnetically attracted, and the top of the strong permanent magnet 12 is provided with an arc-shaped interference block 13, and the opened periosteum separation plate 11 is convenient to separate the The periosteum is stretched to expand the field of vision and facilitate the operation. During the process, by using the magnetism of the strong permanent magnet 12, it is convenient to adjust its position on the limit plate 5, so it is convenient to adjust the inclination angle of the periosteal separation plate 11 to achieve The best periosteal peeling effect.

Embodiment 3, on the basis of Embodiment 1, one end of the handle 1 is provided with a peeling shovel 14, a side of the peeling shovel 14 close to the handle 1 is installed with a screw 15, and the peeling shovel 14 is threadedly connected to the handle 1 through the screw 15, and the handle 1 One end of the screw is provided with a threaded groove that matches the screw 15, and the inner wall of the threaded groove is installed with a second compression spring 16. By setting the peeling shovel 14, it is convenient for the user to separate the periosteum through it.

working principle:

When the periosteum is separated:

The medical staff holds the handle 1 and places the peeling shovel 14 on the site where the operation needs to be performed, so as to facilitate the periosteum separation operation. The opened periosteum separation plate 11 is convenient to spread the separated periosteum, thereby expanding the field of view and facilitating the operation. In the middle, by using the magnetism of the strong permanent magnet 12, it is convenient to adjust its position on the limit plate 5, and by setting the arc-shaped interference block 13, the friction force between the periosteal separation plate 11 and the strong permanent magnet 12 is reduced, so it is convenient to Adjust the inclination angle of the periosteum separation plate 11 to achieve the best periosteal peeling effect. By setting the screw 15, it is convenient to install the peeling shovel 14 before the periosteum separation and disassemble the peeling shovel 14 after the periosteum separation, thereby preventing the user from passing the rasp peak 4 to the shovel. When the lesion site is gently filed to remove the bone spurs on the bone, there is a problem that the peeling spatula 14 follows the movement and damages the patient.

When a healthcare provider files a spur from a patient's bone:

After the periosteum is separated, the medical staff holds the handle 1, and pushes against the abutment plate 6 through the thumb or index finger, drives the file plate 3 to slide down in the through groove 2 through the insertion rod 7, and makes the file peak 4 protrude from the through groove 2. , at this time, move the handle 1, so that the medical staff can use the file peak 4 to remove the bone spur on the bone of the patient's lesion, so as to effectively solve the problem of the bone spur compressing the spinal cord or compressing the nerve, and prevent the patient from continuing to suffer from joint pain and motor dysfunction. .
