Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a hook for severing the anterior cruciate ligament of a miniature pig. Background Art
[0002] Osteoarthritis is a degenerative disease, and its global prevalence is increasing. Currently, the pathogenesis of this disease is not clear. The animal model of OA is an important means for studying the pathogenesis, preventive intervention and treatment of this disease.
[0003] Currently, when researchers create an OA model for miniature pigs, they mainly use the method of severing the anterior cruciate ligament. Currently, there is no specific surgical instrument for severing the anterior cruciate ligament, and researchers mostly use a conventional scalpel to sever the anterior cruciate ligament.
[0004] Since the position of the anterior cruciate ligament of a miniature pig is relatively deep and there are many adjacent structures around it, the inventor found that when using a scalpel to sever the anterior cruciate ligament, it is easy to cause damage to the internal soft tissues and articular cartilage in the joint cavity. Content of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies of the above traditional technologies and provide a
[0006] The purpose of the utility model is achieved by the following technical measures: A hook for severing the anterior cruciate ligament of a miniature pig, characterized in that: it includes a handle, a long handle and a hook. One end of the handle is fixedly connected to the long handle, and the end of the long handle away from the handle is fixedly connected to the hook. The hook is in an arc shape. The handle, the long handle and the hook are integrally formed. The hook includes a starting section and an ending section. The end of the long handle away from the handle is fixedly connected to the starting section. A blade is arranged on the inner side surface of the starting section, and the blade is arranged in a serrated shape. The starting section accounts for two-thirds of the length of the hook, and the ending section is a smooth surface.
[0007] As a preferred scheme: The hook is a 1 / 6 arc of a circle with a diameter of 5 mm.
[0008] As a preferred scheme: The handle is in a cylindrical shape, the length of the handle is 45 mm, the bottom diameter of the handle is 3 mm, and the surface of the handle is provided with threads to prevent slipping.
[0009] As a preferred scheme: The length of the long handle is 105 mm, and the surface of the long handle is smoothly arranged.
[0010] As a preferred scheme: The handle, the long handle and the hook are all made of metal materials.
[0011] Due to adopting the above technical scheme, compared with the prior art, the advantages of the utility model are:
[0012] The utility model utilizes a long handle and a serrated hook to more accurately sever the anterior cruciate ligament of a miniature pig, avoiding the damage to other tissue structures caused by using a scalpel for severance at present. Since the inner side of the hook has a blade, it can accurately lift and cut off the anterior cruciate ligament of the miniature pig in a smaller surgical field, with accuracy and also conducive to avoiding damage to other tissue structures.
[0013] The following further describes the utility model in conjunction with the drawings and specific embodiments. Description of the Drawings
[0014] Attached Figure 1 is the overall structural schematic diagram of a severing probe for the anterior cruciate ligament of a miniature pig of the utility model.
[0015] Attached Figure 2 is the structural schematic diagram of the hook in the utility model. Specific Embodiments
[0016] Embodiment: As shown in Attached Figure 1 and Attached Figure 2 A severing probe for the anterior cruciate ligament of a miniature pig includes a handle 1, a long handle 2 and a hook 3. One end of the handle 1 is fixedly connected to the long handle 2, and the end of the long handle 2 away from the handle 1 is fixedly connected to the hook 3. The hook 3 is in an arc shape. The handle 1, the long handle 2 and the hook 3 are integrally formed. The hook 3 includes a starting section 31 and an ending section 32. The end of the long handle 2 away from the handle 1 is fixedly connected to the starting section 31. The inner side of the starting section 31 is provided with a blade, and the blade is in a serrated shape. The starting section 31 accounts for two-thirds of the length of the hook 3. The ending section 32 is a smooth surface, and the end of the ending section 32 away from the long handle 2 is in an arc shape.
[0017] The hook 3 is a 1 / 6 arc of a circle with a diameter of 5 mm.
[0018] The handle 1 is in a cylindrical shape. The length of the handle 1 is 45 mm, and the bottom diameter of the handle 1 is 3 mm. The surface of the handle is provided with threads to prevent slipping.
[0019] The length of the long handle 2 is 105 mm, and the surface of the long handle 2 is smooth.
[0020] The handle 1, the long handle 2 and the hook 3 are all made of metal materials.
[0021] The long handle 2 and the hook 3 can more accurately sever the anterior cruciate ligament of the miniature pig, avoiding the damage to other tissue structures caused by using a scalpel for severance at present; since the inner side of the hook 3 has a blade, it can accurately lift and cut off the anterior cruciate ligament of the miniature pig in a relatively small surgical field, with accuracy and also conducive to avoiding damage to other tissue structures.
