Stitching instrument for thoracoscope minimally invasive surgery and control system

Abstract

The invention belongs to the technical field of medical instruments, and discloses a stitching instrument for thoracoscope minimally invasive surgery and a control system. A supporting block is weldedto the right end of a sleeve, a groove is formed in the supporting block, and a pressure sensor is fixed to the bottom of the groove through a screw; a rotating rod is fixed to the sleeve through a ferrule, a hook is welded to the right end of the rotating rod, and a screwing handle is welded to the left end of the rotating rod; and a swing rod is fixed to the sleeve through a rotating shaft, a stirring handle is welded to the left end of the swing rod, a suture needle is welded to the right end of the swing rod, and a suture clamping groove is formed in the suture needle. A fixed supportingrod is welded to the left end of the sleeve, a thread inlet groove is formed in the inner side of the sleeve, and the thread inlet groove sleeves a sewing thread. The shifting handle is provided witha telescopic outer cylinder, and an anti-skid pad is adhered to the outer side of the telescopic outer cylinder; the telescopic outer cylinder is connected with a fixing bolt in a screwed mode, the fixing bolt makes hard contact with a telescopic inner rod, and the telescopic inner rod is sleeved in the telescopic outer cylinder. According to the invention, the suture needle can be ensured to penetrate through human tissues for suture, operation safety is improved, and the suture time can be shortened.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a stapler and a control system for thoracoscopic minimally invasive surgery. Background technique [0002] Currently, thoracoscopic surgery is the abbreviation of Video-Assisted Thoracoscopic Surgery (VATS). Thoracoscopic surgery is regarded as a revolutionary breakthrough in the field of thoracic surgery at the end of the 20th century, and it is the most widely used thoracic surgery in minimally invasive thoracic surgery. During thoracoscopic surgery, a stapler can be used to knot the suture thread for tissue suturing, wherein the stapler plays a key role. However, the existing stapler for thoracoscopic minimally invasive surgery is not easy to accurately judge whether the sewing needle passes through human tissue, which reduces the safety of the operation and prolongs the time for surgical suturing. In addition, during the use of the existing staplers for ...
