Description
Technical Field
The invention relates to a disposable endoscopic incision anastomat, which belongs to medical instruments and is particularly suitable for a disposable endoscopic incision anastomat for applying a linear row on intracavity tissues.
Background
Traditional surgical procedures include cutting, separating, ligating, hemostasis, suturing, and ultimately resection of an organ lesion and reconstruction of the organ. The mechanical stitching instrument can replace the traditional operation, and realize the excision and reconstruction of the lesion organ through the following three basic operations: 1. separating: the method is characterized in that a linear stitching instrument is used for stitching an organ at a certain distance from a lesion, including a parenchymal organ, a cavity organ, a blood vessel and the like, and then the lesion organ is cut off, or the stitching and the cutting are completed at one time by using a linear cutting stitching instrument. 2. I.e., the tissue to be sutured is apposed and stapled with a linear stapler, e.g., a transverse slit cut longitudinally at the pylorus, to complete the pyloric procedure. 3. The end-to-end anastomosis and the end-to-side anastomosis can be conveniently carried out on the cavity organs such as esophagus, stomach, small intestine and colon by using the annular anastomat. The gastrointestinal side-to-side anastomosis can be performed by using a cutting stapler. Such as colorectal end-to-end anastomosis, esophagogastrogastric end-to-side anastomosis, and gastrojejunal side-to-side anastomosis.
In laparoscopic and or endoscopic procedures, the procedure is performed through a small incision or narrow cannula inserted through a wound in the patient. In a conventional or open procedure, the surgeon directly contacts the surgical site. Laparoscopic surgery has advantages over open surgery due to its reduced patient trauma, shortened patient recovery period and significantly reduced overall costs. To accommodate the specific needs of both endoscopic and abdominal approaches, endoscopic suturing devices have been developed to provide easier access to the surgical site for the surgeon. Typically, these stapling instruments include an articulatable tool component supported proximate the end of the stapling apparatus. The tool assembly is selectively manipulable to enable a surgeon to manipulate the surgical device within a confined space. These instruments provide significant medical benefits to endoscopic procedures. Nevertheless, improvements in cost reduction and manufacturing complexity are desired.
In the current endoscope internal cutting anastomat, both hands are needed for operation, the operation of a doctor is not smooth enough, and the interior of the endoscope internal cutting anastomat is a plastic part, so that the strength is not enough, and the operation failure can be caused.
There remains a need for further improvements to reduce the time required for surgical procedures and to make staplers more accessible to tissue sites, stronger, and with more suction on the jaws.

The movable handle is pulled again, the rack driving block pushes the rack, the band cutter rod, the band blade and the cutter to cut tissues forwards, and meanwhile, the cutter pushes the beveling, the pushing piece and the anastomosis nail to perform anastomosis tissues.
At the moment, the position of the limit plate spring is limited by the trigger block limiting plate in the stopping safety, the sliding boss on one side of the upper portion of the trigger block limiting plate slides in the trigger block limiting plate sliding groove on the rack, the limit boss on the lower portion of the trigger block limiting plate moves upwards to block the trigger block and the trigger block upper cover, the jaw caused by backward movement of the trigger block and the trigger block upper cover is prevented from being opened, and the stopping safety effect is achieved.
The reset handle is pulled, the cutter is pulled back and reset through the reset rod, the rack, the cutter rod and the blade, the jaw is opened simultaneously, the front end of the disposable endoscopic incision anastomat is withdrawn from the tissue, and the incision anastomosis operation in the cavity is completed.
When the front end of the disposable endoscopic incision anastomat is inserted into tissues, if the angle is not suitable for percussion and needs to be adjusted, the forefinger can be used for pulling the rotating handle, the steering drag hook and the steering pin block are pulled through the upper rotating block and the lower rotating block, the angle can be adjusted, after the angle is adjusted, the middle finger pulls the movable handle, the jaw is closed, and the movable handle is pulled again to complete percussion.
The disposable endoscope internal cutting anastomat has the advantages that:
the existing abdominal cavity internal cutting anastomat is fixed by a nail bin seat, and the nail bin seat, the nail bin, the anastomat and the like are inserted into tissues when the anastomotic tissues are cut, so that on one hand, the thickness of the part of the anastomat is thicker, and a larger space is needed, and on the other hand, the anastomotic nails in the nail bin are easily taken out by the tissues when the anastomat is inserted, so that incomplete anastomosis is caused. The disposable endoscope internal cutting anastomat is fixed by the nail abutting seat, the tissue is inserted into the nail abutting seat, the nail abutting seat is thin, the space required for inserting the tissue is smaller, the anastomosis nail is not contacted with the tissue before being triggered, and the risk that the tissue takes out the anastomosis nail and the tissue is incompletely sutured is avoided.
Due to the arrangement of the knife stopping safety device, before percussion, the reset handle can be effectively prevented from being manually pushed carelessly, the rack is driven to slide forwards, the cutting knife is driven to move, and anastomotic nails fall out.
Due to the arrangement of the backstop safety device, the jaw can not be closed easily before being fired, and the jaw can not be opened again during firing, so that incompact anastomosis caused by incompact clamping of tissues can be avoided.
Because the movable handle is arranged, the operation can be carried out by one hand no matter the angle is adjusted or the percussion is finished, so that doctors can spare hands to operate other instruments, and the operation is more smoothly finished.
Due to the arrangement of the clamping anastomosis component steering device, in the operation process, the angles of the nail bin and the nail supporting seat at the front end of the disposable endoscopic incision anastomat can be adjusted randomly in a narrow space in the cavity, so that the operation is more smoothly completed.
