Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely especially relates to a roller formula bone wax applicator for UBE spine endoscope operation. BACKGROUND

[0002] UBE is under endoscope spinal minimally invasive surgery treatment, generally carries out in water medium, removes part of bone in operation, but the bone surface of some patients after resection bleeds seriously, and bone wax hemostasis is a good method, but it is difficult to safely and effectively smear bone wax on the bone surface in water medium:

[0003] The present generally uses small bone stripping head to smear a little bone wax, and then smears it on the bone surface, because the operation is carried out in water medium, the bone stripping often does not reach the bone surface, and the bone wax is washed away by water, sometimes it needs to be repeatedly smeared for many times, and the bone wax left in the wound by water is taken out, which prolongs the operation time.

[0004] In addition, because the operation is minimally invasive surgery, the incision is small, and the bleeding bone surface is irregular, sometimes the bone surface bleeds, and the operator is difficult to smear through bone stripping. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a roller formula bone wax applicator for UBE spine endoscope operation, which can uniformly smear bone wax on the surface of bone tissue to solve the problems in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model realizes the following technical means:

[0007] A roller formula bone wax applicator for UBE spine endoscope operation, which comprises a roller formula smearing part, a connecting rod and a handle connected in sequence, the roller formula smearing part comprises an adapter connected with the connecting rod, the adapter is fixedly connected with a roller mounting seat through a fixing cap, a roller is movably assembled on the roller mounting seat through a guide column, a limiting piece for limiting the roller is arranged at the other end of the guide column, and the working surface of the roller is a rough surface.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model can evenly apply bone wax on the surface of bone tissue. The roller design makes the operation more convenient, and the bone wax can be applied to the required parts accurately and evenly. The working surface of the roller is designed to be a granular rough surface, which can better grasp and carry the bone wax, ensuring that the bone wax can be more firmly attached to the roller and evenly applied, and the bone wax can be more effectively pushed away and fill some tiny gaps or irregular surfaces, and more bone wax can be carried. During operation, the medical staff's hand force is more natural and comfortable, and the medical staff can more easily perform the application action during use, reducing operating fatigue; it can also make the direction and range of application easier to control, so that the bone wax can be more accurately applied to the target area, improving the accuracy and efficiency of the operation.

[0029] UBE is a minimally invasive spinal surgery performed under endoscopy, usually in aqueous media. During the procedure, bone is partially removed. However, some patients bleed severely from the bone surface after resection. Bone wax is a good method for hemostasis, but it is difficult to apply bone wax safely and effectively to the bone surface in aqueous media.

[0030] Currently, a small amount of bone wax is generally applied to the head of a small bone peeler and then applied to the bone surface. Since the operation is performed in a water medium, the bone wax is often washed away by water before the bone peeler reaches the bone surface. Sometimes, the bone wax must be applied repeatedly, and the bone wax left in the wound after being washed away by water must be removed, which prolongs the operation time.

[0031] In addition, because the operation is a minimally invasive operation, the incision is small, the bleeding bone surface is irregular, and sometimes the bone surface bleeds, which makes it difficult for the operator to apply the blood through bone peeling.

[0032] In this embodiment, a roller-type bone wax applicator for UBE spinal endoscopic surgery includes a roller-type applicator 1, a connecting rod 2, and a handle 3 connected in sequence. The roller-type applicator 1 includes an adapter 4 connected to the connecting rod 2, and the adapter 4 is fixedly connected to a roller mounting seat 6 through a fixing cap 5.

The working surface of the roller 7 is a rough surface. The utility model can evenly apply bone wax on the surface of bone tissue. The roller-type design can make the operation more convenient, accurate and uniform. Bone wax is evenly applied to the required area. The working surface of the roller 7 is designed to be a granular rough surface, which can better grasp and carry the bone wax, ensure that the bone wax can be more firmly attached to the roller 7 and evenly applied, and more bone wax can be pushed away and filled with some tiny gaps or irregular surfaces more effectively. During operation, the medical staff's hand force is more natural and comfortable, and the medical staff can more easily perform the application action during use, reducing operating fatigue; it can also make the application direction and range easier to control, so that the bone wax can be applied to the target area more accurately, improving the accuracy and efficiency of the operation.
