Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ankylosing spondylitis endoscopic surgery assistant. Background Art

[0002] Ankylosing spondylitis is a common disease in rheumatology and orthopedics. Its main symptoms are inflammation of the sacroiliac joints and spinal attachment points, and its pathological features are fibrosis and ossification of the intervertebral disc annulus and nearby connective tissue, as well as joint ankylosis. It is an autoimmune disease. In the early stage, there is inflammatory pain in the joints at the lesion site, accompanied by muscle spasms around the joints and stiffness, which is more obvious in the morning. In order to better treat patients with ankylosing spondylosis, auxiliary equipment is needed when using an endoscope.

[0003] At present, most of the ankylosing spondylitis endoscopic surgery assistants need manual support from medical staff when in use. Long-term holding will cause fatigue and muscle stiffness of medical staff, thus seriously consuming the physical strength of medical staff. Therefore, those skilled in the art provide an ankylosing spondylitis endoscopic surgery assistant to solve the problems raised in the above background technology. Utility Model Content

[0007] Through the above technical solution, under the action of the guide rod, the two connecting blocks can be limited, and the two sets of limit blocks can be used to effectively prevent the screw rod from rotating when moving.

[0008] Furthermore, one end of each of the two screw rods is fixedly connected to a mounting block, a damping shaft is commonly provided between the two mounting blocks, and a rotating block is provided on the outer wall of the damping shaft;

[0009] Through the above technical solution, under the cooperation of the mounting block and the damping shaft, the rotating block can be rotated better.

[0010] Furthermore, a through groove is provided on the upper surface of the rotating block, an anti-sliding block is fixedly provided on the inner wall of the through groove and a sliding groove is provided, and a clamping block is slidably provided on the inner wall of the sliding groove;

[0011] Through the above technical solution, with the cooperation of the anti-sliding block and the clamping block, the catheter during the operation can be clamped and fixed, thereby effectively freeing the hands of medical staff.

[0012] Furthermore, a bolt is threadedly connected to one side wall of the rotating block, and one end of the bolt is rotatably connected to the clamping block;

[0013] Through the above technical solution, under the action of the bolt, the clamping block can be moved inwards, thereby fixing the catheter.

[0014] Furthermore, a group of screws are threadedly penetrated through the lower surfaces of the two fixing frames, and the upper ends of the two groups of screws are rotatably connected to clamping blocks;

[0015] Through the above technical solution, the two connecting blocks can be fixed under the cooperation of the screw rod and the clamping block.

[0016] Furthermore, a threaded sleeve is rotatably provided on one side wall of the fixed block, and the threaded sleeve is threadedly connected to a screw rod on one side;

[0017] Through the above technical solution, the two screw rods are moved under the rotation of the threaded sleeve, so as to facilitate flexible adjustment according to the surgical site of the patient.

[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the existing ankylosing spondylitis endoscopic surgery assistant, the utility model proposes an ankylosing spondylitis endoscopic surgery assistant. When the assistant is put into use, under the action of the guide rod and the cooperation of the two sets of limit blocks, the threaded sleeve is rotated to make the two screws slide between the fixed blocks, thereby driving the movement of the rotating block, which is convenient for flexible adjustment according to the patient's surgical site.

[0020] 2. Compared with the existing ankylosing spondylitis endoscopic surgery assistant, the utility model proposes an ankylosing spondylitis endoscopic surgery assistant. When the assistant is put into use, the angle of the rotating block can be flexibly adjusted under the cooperation of the damping shaft and the rotating block. Through the cooperation between the anti-sliding block, the clamping block and the bolt, the medical staff can turn the bolt to make the clamping block firmly clamp and fix the catheter used in the operation, thereby freeing the hands of the medical staff.
