Description

Technical Field

[0001] The utility model relates to the field of meniscus hooks, in particular to a meniscus hook. Background Art

[0002] The meniscus is a fibrous cartilage located between the articular surface of the tibial plateau and the femoral condyle. It has a thick outer edge that is attached to the joint capsule, a thin and sharp middle that is free in the joint cavity, and a triangular cross section. It is slightly concave on the upper side and relatively flat on the lower side. The meniscus is divided into the medial meniscus and the lateral meniscus. The medial meniscus is C-shaped, and the lateral meniscus is O-shaped. The outer edge of the meniscus has blood supply, while the inner edge does not. The function of the meniscus is to stabilize the knee joint, transmit the load force of the knee joint, and promote nutrition within the joint. Meniscus plays a very important role in the movement of joints, therefore, meniscus injury is also very common. Meniscus injury is generally sports injury, but also caused by senile wear and tear. Another common injury is congenital meniscus malformation, namely discoid meniscus. Normal meniscus is crescent-shaped, while discoid meniscus is disc-shaped, which is larger and thicker than normal meniscus and prone to tearing. When inspecting the meniscus after it is damaged, it is usually necessary to use a meniscus probe to assist in the inspection.

[0003] Currently, the existing meniscus probe hook is usually formed by stamping and has a fixed length. As a result, when the probe hook is inserted into the patient's affected area, the fixed length of the probe hook cannot meet the use requirements of medical staff, making it difficult to insert the probe hook into the patient's affected area. Instead, a meniscus probe hook with an appropriate length needs to be replaced, which reduces the scope of application of the meniscus hook. For this reason, we propose a meniscus hook. Utility Model Content

[0004] The purpose of the utility model is to provide a meniscus hook in order to solve the problem that the applicable range of the meniscus hook is limited when the length is fixed.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a meniscus hook, comprising a handle and a hook rod disposed inside the handle and extending to one end of the outer wall, characterized in that a telescopic mechanism is disposed inside and outside the handle;

[0006] The telescopic mechanism includes a mounting groove arranged inside the handle, a fixed block for improving the stability of the hook rod when moving is fixedly connected to the inside of the mounting groove, a fixing ring is fixedly connected to the outer wall of the hook rod, an operating rod extending to the outer wall of the handle is fixedly connected to the outer wall of the fixing ring, a connecting groove extending to the outer wall of the handle is provided inside the handle, a limiting groove located on one side of the connecting groove is also provided inside the handle, and a telescopic spring is sleeved on the outer wall of the hook rod.

[0007] As a further solution of the present invention: a through hole matching the diameter of the outer wall of the hook rod is provided inside the fixing block, and the hook rod is slidably connected to the fixing ring through the through hole.

[0008] As a further solution of the present invention: a plurality of the limiting grooves are provided, and the plurality of limiting grooves are arranged at equal distances.

[0009] As a further solution of the present invention: a through groove is provided between the connecting groove and the limiting groove, and the connecting groove and the plurality of limiting grooves are interconnected through the through groove.

[0010] As a further solution of the present invention: the inner width of the limiting groove matches the outer wall diameter of the operating rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By setting up a telescopic mechanism, the operating rod is pushed to drive the fixed ring to move and compress the telescopic spring. The fixed ring moves to drive the hook rod to move, and the hook rod moves to drive the probe hook to extend in the direction away from the grip. When the hook rod is extended to a position that meets the inspection requirements, the operating rod is rotated horizontally to allow the operating rod to pass through the through slot and enter the interior of the limiting slot. At this time, the resetting effect of the telescopic spring pushes the fixed block in the opposite direction, and the movement of the fixed block drives the operating rod to move. The operating rod moves and fits into one end of the interior of the limiting slot, completing the limiting operation of the operating rod. At this time, holding the grip can complete the extension operation of the hook rod, thereby facilitating medical staff to perform inspection operations on patients.
