Shoulder arthroscopy minimally invasive surgery traction device

Abstract

The present invention relates to the technical field of surgical traction devices and also discloses a shoulder arthroscopy minimally invasive surgery traction device. The shoulder arthroscopy minimally invasive surgery traction device comprises a fixing base, a top part of the fixing base is fixedly connected with a supporting tube, an inner part of the supporting tube is slidably connected witha telescopic rod, a row of threaded holes are arranged in a side wall of the telescopic rod, a limiting screw matching the threaded holes sleeves on a tube wall of the supporting tube, a first U-shaped seat is fixedly connected with a top part of the telescopic rod, the first U-shaped seat is internally rotatably connected with a support rod via a rotating rod, one end of the support rod far awayfrom the telescopic rod is fixedly connected with a connecting plate, the connecting plate is fixedly connected with a traction mechanism by a bolt, the traction mechanism comprises a first threaded rod, a threaded sleeve and a second threaded rod, the first thread rod is connected with the connecting plate by a bolt, and both ends of the threaded sleeve are respectively screwed with the first threaded rod and the second threaded rod. The shoulder arthroscopy minimally invasive surgery traction device can be finely adjusted when a traction rope is used for traction, and avoid secondary injuryto patients' shoulders.

Description

technical field [0001] The invention relates to the technical field of surgical traction devices, in particular to a traction device for shoulder arthroscopic minimally invasive surgery. Background technique [0002] Due to the special anatomical structure of the shoulder joint, patients with shoulder arthritis, biceps brachii rupture, and osteoarthritis usually need to use the lateral position when undergoing shoulder arthroscopic surgery. Use upper extremity traction devices to maintain extremity abduction design requirements. Shoulder arthroscopic surgery is suitable for joint loose body, biceps rupture, osteoarthritis and other surgical treatments. Minimally invasive shoulder arthroscopic surgery requires the patient to open the joint space of the patient's shoulder joint through an auxiliary traction device in a side-lying state, and then the surgical operation can be performed. Generally, a traction rope is used for inclined stretching, but the pulling degree of the ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a traction device for shoulder arthroscopic minimally invasive surgery, which has the advantage of being able to fine-tune when the traction rope is pulled to avoid secondary injury to the patient's shoulder, and solves the problem of In the prior art, the pulling degree of the pulling rope is completely dependent on the doctor's experience when pulling, and it is inconvenient to fine-tune the pulling rope when pulling, and it is easy to cause secondary injury to the patient's shoulder
