[0003] In order to clamp the ribs, the grip of the adjustable chest opener for general thoracic surgery is generally a concave structure, and the size of the notch of the concave shape is not variable, and the grip of the chest opener cannot match the rib size of different patients To adjust the size of the clamping notch, the clamping notch of the dial does not match the rib of the patient. During the thoracotomy, the patient's ribs will slide and rub against the clamping gap of the dial, which may easily cause rib damage

Abstract
The invention discloses an adjustable thoracotomy device for a general thoracic surgery. The thoracotomy device structurally comprises a debugging rod, a chest opening block, a fixing rod, telescopic blocks and a shifting claw, the chest opening block penetrates through the debugging rod, the debugging rod is in clearance fit with the chest opening block, the fixing rod is arranged in the chest opening block, the chest opening block is in threaded connection with the fixing rod, and the shifting claw is installed on the chest opening block and is in sliding connection with the chest opening block. The telescopic blocks are installed on both sides of the debugging rod, and the telescopic blocks are in interference- fitwith the debugging rod, and a clamping groove is provided on the chest opening block. The thoracotomy device can adjust the groove suitable for clamping the patient's ribs by extending and shortening an extension structure, and reduce the clamping gap when the shifting claw and the ribs are clamped. The matching fitting degree of the clamping notch of the shifting claw and the ribs needing to be clamped by the patient is increased, and when the equipment is used for clamping and opening the chest, the ribs of the patient cannot slide in the clamping gap of the poking claw and cannot be damaged.
Description
technical field [0001] The invention relates to the field of thoracic surgery, in particular to an adjustable chest opener for general thoracic surgery. Background technique [0002] Thoracic surgery is a medical specialty that specializes in the study of thoracic organs, mainly referring to the diagnosis and treatment of esophageal, lung, and mediastinal lesions. During thoracic surgery, an adjustable general thoracic surgery chest opener is usually used to open the ribs to expose surgical field of view; [0003] In order to clamp the ribs, the grip of the adjustable chest opener for general thoracic surgery is generally a concave structure, and the size of the notch of the concave shape is not variable, and the grip of the chest opener cannot match the rib size of different patients To adjust the size of the clamping notch will cause the clamping notch of the dial to not match the patient's ribs. During the thoracotomy process, the patient's ribs will slide and rub agains...
