Retractors used for thoracic operations

Abstract

The invention discloses retractors used for thoracic operations, and relates to the field of medical instruments. The retractors used for the thoracic operations mainly comprises a bed frame; a slidebar is arranged on the bed frame; one end of the slide bar is fixed on a slide bar bracket; a slide sleeve is arranged, far away from the slide bar bracket, at one end of the slide bar; short hooks and long hooks are hung, with intervals of certain distances between, on the slide sleeve; a screw rod is driven to move upward by a rotating hand-wheel shaft, thereby jacking-up the slide bar bracket so as to make the slide bar to tilt upward; and thus, the retractors on the long hooks and the short hooks tilt upward along with the tilting of the slide bar while carrying out linear motion, therebypropping open of intercostal space to facilitate performance of a thoracic operation. The retractors used for the thoracic operations have the following beneficial effects: the retractors used for thethoracic operations is capable of adjusting expansion range in adaption to sizes of the sternum, the chest wall and the thoracic cavity according to operation requirements by hanging retractors of different types, thereby achieving the optimal exposure effects; medical staff can accurately adjust and expand the size of the sternum, the chest wall and the thoracic cavity by directly operating theretractors without help of the power of the hands; and the retractors are suitable for total thoracoscopic surgeries for thoracic diseases, including breast cancer, thyroid carcinoma, lung cancer, esophageal cancer and the like.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a retractor used for thoracic surgery. Background technique [0002] In thoracic surgery, under the existing medical conditions, medical staff generally need to hold the retractor and use the strength of the hand to expand the size of the breastbone, chest wall and chest cavity. This operation is laborious and difficult to achieve precise adjustment and control. Medical staff with small hand strength caused great distress, which was not conducive to safe and efficient operation. In addition, when the surgical site is deep, it is difficult to fully expose the surgical field only by relying on existing medical instruments, and it is difficult for the light source to directly illuminate the chest cavity, which makes the operation more difficult. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a r...

Problems solved by technology

[0002] In thoracic surgery, under the existing medical conditions, medical personnel generally need to expand the size of the sternum, chest wall and chest cavity by holding the retractor and using hand strength. Such an operation is laborious and difficult to achieve precise adjustment and control. Medical staff with weak hand strength brings great troubles, which is not conducive to safe and efficient operation

In addition, when the surgical site is deep, it is difficult to fully expose the surgical field of view and the light source directly into the thoracic cavity only by relying on existing medical equipment, which adds great difficulty to the smooth operation
