Anastomat for surgical operation

Abstract

The invention discloses an anastomat for a surgical operation. The anastomat comprises a shell, the shell is internally provided with a jaw automatic opening device, the jaw automatic opening device comprises a clamping hook and a rack, the rack is movably installed in the shell, and a baffle block is arranged on the rack; the clamping hook is provided with a protrusion cooperating with the baffleblock, when the clamping hook moves backwards, the protrusion acts on the baffle block to drive the rack to move backwards, a trigger is further installed on a clamping hook shell, and a rack linkingdevice is arranged between the trigger and the rack. After a doctor triggers the trigger to close a nail box jaw to clamp the human tissue which needs to be excised, if the doctor thinks that the clamping part is not ideal, the jaw is opened simply by loosening the trigger; when the ideal part desired by the doctor is clamped, the doctor operates a security device, stirs a push rod once and thenloosens the trigger, and the anastomat enters the triggerable state so that the doctor can trigger the trigger again to cut and suture the tissue.

Description

technical field [0001] The present invention relates to a stapler for surgical operations. Background technique [0002] In surgical operations, minimally invasive surgery only needs to make 3 to 5 small incisions on the patient's body, establish a narrow and long instrument channel, and extend the instrument with a slender rod into the body to cut and suture the diseased tissue. The excised diseased tissue is removed from the channel. Minimally invasive surgery has the advantages of small local trauma, mild systemic reaction, and quick postoperative recovery. So it has been widely used. [0003] The surgical stapler involved in the present invention is a surgical instrument used in minimally invasive or open surgery for resection, transection and suture of lung, bronchial tissue, stomach, intestine, etc. In use, a replaceable disposable magazine is attached to the front end of the instrument. In the initial state, the front end of the disposable magazine is a jaw that o...

Problems solved by technology

[0004] At present, the existing products on the market have the following disadvantages: ①The nail box disassembly button is designed at the front end of the instrument shaft. Because of the limitation of the narrow and long instrument channel established during minimally invasive surgery, the size of the button is very small. It cannot be higher than the outer surface of the instrument shaft. When disassembling the nail box, you need to press the button with your fingernail

However, the operating environment is a sterile operating room. Doctors wear gloves on both hands during the operation. When wearing gloves, it will be quite laborious to press the button with fingernails, and the operation is inconvenient.

②When the doctor operates the instrument to close the jaws of the nail magazine to clamp the human tissue to be resected, if it is found that the clamped part is not ideal, when it is necessary to open the jaws to re-clamp, the existing instrument requires the doctor to hold it firmly with one hand With the other hand, pull the firing rod reset push button back to the original position

This brings great inconvenience to the doctor's operation, because in minimally invasive surgery, sometimes the doctor needs two hands to operate two instruments with different functions at the same time to perform the operation. button

Moreover, such instruments cannot double as the function of grasping forceps
