Abstract

The invention discloses a retractable cutting and suturing machine, and belongs to the field of cutting and suturing machines in medical apparatuses. The retractable cutting and suturing machine structurally comprises an outer tube and a handle arranged at the rear end of the outer tube. The retractable cutting and suturing machine is characterized by also comprising a first supporting rod, a second supporting rod, a first seam cutting mechanism, a second seam cutting mechanism, an aperture angle regulating assembly, an opening and closing control assembly and a driving assembly, wherein the front end of the outer tube is hinged to the rear end of the first supporting rod and the rear end of the second supporting rod; the front end of the first supporting rod is hinged to the rear end of the first seam cutting mechanism, and the front end of the second supporting rod is hinged to the rear end of the second seam cutting mechanism; and the front end of the first seam cutting mechanism and the front end of the second seam cutting mechanism are in transmission connection with the aperture angle regulating assembly. Compared with the prior art, the retractable cutting and suturing machine disclosed by the invention has the characteristics that wounds are small, and cutting and suturing can be completed in one time.

Description

technical field [0001] The invention relates to the field of cutting and stapling devices in medical instruments, in particular to a retractable cutting and stapling device. Background technique [0002] In surgical operations, medical staplers have become an indispensable auxiliary medical device in the process of suturing human tissues. The scope of application involves thoracic surgery, gastrointestinal surgery, etc. It has the advantages of less intraoperative bleeding, short operation time, and reduced manual errors. Many advantages. [0003] Taking thoracic surgery as an example, at present, wedge-shaped lung tissue examination is the main method for obtaining pathological specimens and treating them clinically. Wedge resection is to cut and suture the tissue to be cut multiple times with a linear cutting and suturing device under the thoracoscope. There are problems such as large surgical incision, large trauma, and difficult control of the cutting margin. Contents...
