Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a ligament spatula for animal surgery. Background Art
[0002] Hip replacement is a common orthopedic surgery, which requires dislocation and removal of the femoral head. The round ligament of the femoral head is one of the obstacles to the smooth removal of the femoral head. When the femoral head is removed, it will be blocked by the round ligament of the femoral head. When removing the femoral head, care must be taken not to damage important structures. For example, when performing hemi-hip replacement, the acetabulum, cartilage, and labrum must be protected. In the past, head removers did not have the function of cutting the round ligament of the femoral head, or used sharp instruments to cut the round ligament of the femoral head, which did not protect important tissues. Currently, all femoral head removers are used, which are pulled, rotated, or pried out violently using the principle of leverage. Removal is time-consuming, laborious, and easy to cause damage.

[0014] Optionally, the middle of the spoon-shaped portion is recessed inward to form a receiving cavity.
[0015] By adopting the above technical solution, the accommodating cavity is used to accommodate the cut and scraped tissues, making it easy to remove these tissues.
[0016] Optionally, the upper surface of the spoon-shaped portion is configured as a curved surface for fitting the surface of the femoral head.
[0017] By adopting the above technical solution, the arc surface is provided so that the cutting part fits on the surface of the femoral head after entering between the acetabulum and the femoral head, thereby improving the effect of cutting the round ligament.
[0018] Optionally, an inclined portion is provided at the connection between the ligament shovel body and the spoon-shaped portion, the inclined portion is connected to the arcuate surface, and the inclined portion extends along the tangent direction of the arcuate surface.

[0029] The following is combined with Figure 1-4 This application is described in further detail.
[0030] This embodiment discloses a ligament spatula for animal surgery.
[0031] Reference Figure 1 and Figure 2 A ligament spatula for animal surgery comprises a ligament spatula body 2, a gripping portion 1 is arranged in the middle of the ligament spatula body 2, the diameter of the gripping portion 1 is larger than the diameter of the ligament spatula body 2, the connection between the gripping portion 1 and the ligament spatula body 2 is in a step shape, and the surface of the gripping portion 1 is evenly provided with anti-slip patterns 4, cutting portions 3 are arranged at both ends of the ligament spatula body 2, and the cutting portions 3 at the two ends have different sizes, namely a first cutting portion 5 and a second cutting portion 6, and the first cutting portion 5 and the second cutting portion 6 form an angle of 90°.
[0032] Reference Figure 3 and Figure 4 The cutting portion 3 includes a spoon-shaped portion 9, which is spoon-shaped and has an elliptical cross-section. The bottom of the spoon-shaped portion 9 is a convex arc shape. The middle of the spoon-shaped portion 9 is grooved inward to form a receiving cavity 7. The edge of the receiving cavity 7 is polished to form a cutting edge 8. One side of the opening of the spoon-shaped portion 9 is set as an arc surface 10. A slope portion 11 is set at the connection between the ligament shovel main body 2 and the arc surface 10, and the slope portion 11 extends along the tangent direction of the arc surface 10.
[0033] The implementation principle of the ligament shovel for animal surgery in this embodiment is as follows: when performing femoral head surgery on an animal, a cutting portion 3 of a corresponding size is selected according to the animal's body shape. When using the ligament shovel, the operator holds the holding portion 1 of the ligament shovel and inserts one end of the cutting portion 3 into the gap between the acetabulum and the femoral head. The cutting portion 3 is attached to the surface of the femoral head through the arc surface 10. As the cutting portion 3 is inserted, the acetabulum and the femoral head are lifted and separated by the spoon-shaped portion 9, and then the cutting portion 3 is driven to move along the surface of the femoral head, and the edge of the cutting portion 3 is used to cut the femoral head. The opening 8 cuts the round ligament connecting the acetabulum and the femoral head, and the cut tissue enters the accommodating cavity 7 in the middle of the cutting part 3. After driving the cutting part 3 to move around the surface of the femoral head for one circle, the round ligament between the femoral head and the acetabulum is completely cut off, and then the cutting part 3 is moved to the middle position of the femoral head, and the cutting part 3 and the ligament shovel body 2 are used as crowbars to pry the femoral head, and the femoral head and the acetabulum are separated by the action of the lever, thereby realizing the cutting of the round ligament between the femoral head and the acetabulum and the separation of the femoral head and the acetabulum. The operation is simple and the cutting effect is good.
[0034] In summary, the cutting part in the present application is set in a spoon shape, and a cutting edge is set at the edge of the cutting part, and an arc surface is set on the cutting part, so that the cutting part can fit on the surface of the femoral head when in use, effectively realizing the rapid cutting of the round ligament of the femoral head. At the same time, the cutting part and the ligament shovel body are transitionally connected through the inclined portion, and other tissues can be avoided when the ligament shovel is used, avoiding damage to other tissues. The overall structure is simple, easy to use, and the cutting effect is improved, and the scope of application of the ligament shovel is expanded. Therefore, the present application effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
[0035] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present application shall still be included in the protection scope of the present application.
