Description

Celioscope stitching knotter

Technical field

The present invention relates to a kind of operating theater instruments for the treatment of celiac disease, be a kind of can be under the peritoneoscope visual field intraperitoneal maneuverability ground pass the celioscope stitching knotter of line, stitching, knotting and trimming.

Background technology

Recent two decades comes, and many-sided science and technology progress makes laparoscopic surgery that very big development arranged, and the peritoneoscope with Wicresoft's effect has been brought into play big emphatically effect in the diagnosis of celiac disease and treatment.For a laparoscopic procedure person, peritoneoscope is sewed up down, ties a knot, stopped blooding may be most important, the backwardness of celioscope stitching, knotting technology may be a key factor of laparoscopic surgery slower development, also is the high major reason of laparoscopic surgery expense.In traditional abdominal operation process, motor-driven, sew up flexibly, knotting, hemostatic technique be the most basic, also is most important.But under peritoneoscope, the stitching of the sort of maneuverability, knotting technology but do not lose because of having good stitching, knotting technology and apparatus major part.In order to remedy the deficiencies in the prior art, involutory tissue or hemostasis in laparoscopic surgery, select that simple but dangerous heat is coagulated, electricity coagulates (one pole, two utmost points), laser, various clip, staple etc. for use, though operation is simple, but careless manipulation can cause the necrosis of serious hemorrhage or surrounding tissue, causes death.Event is for trunk or organize involutory dangerous position, generally dare not use said method hastily, and uses clumsiness instead but more firm interior knotting method or the ferrule technology sewed up of external knotting, body, and the enforcement of these methods all needs valuable equipment and material.Extensively carry out raising with technology along with laparoscopic surgery, the safety of laparoscopic surgery, effectiveness and invasive are familiar with gradually, range of application is more and more wider, but the distinctive complication of laparoscopic surgery is in case take place, originally the Minimally Invasive Surgery to the patient just changes the lethal operation into, reported literature laparoscopic surgery mortality rate is 4,/10 ten thousand, and " Wicresoft " of laparoscopic surgery also may become " huge wound ".

The day for announcing is on April 26th, 2000, Granted publication number to disclose stitching knotter in a kind of peritoneoscope for the Chinese patent of CN2375257Y, it connects knotting mechanism by joystick and constitutes, knotting mechanism is to form like this: a telescopic end connects handler, turning handle is connected with joystick by contiguous block, the telescopic other end is connected and fixed jaw, connecting rod passes sleeve, its end is connected with joystick, and the other end connects flexible handle, and a telescopic side is provided with a connecting groove.

Open day be that the Chinese patent that February 8, publication number in 2006 are CN1729939A discloses a kind of operating theater instruments for the treatment of celiac disease, especially a kind of celioscope stitching device that can maneuverability is sewed up in abdominal operation.It comprises suture needle, needle stand, handle, lock screw, swingle, suture, and needle stand is for rotating needle stand, and suture needle is fixed on rotates on the needle stand, and the termination of rotating needle stand and swingle is that spiral awl tooth flexibly connects, and swingle is stable at the mobile jib inner chamber.

Summary of the invention

The object of the present invention is to provide a kind of celioscope stitching knotter tool, be a kind ofly can under the peritoneoscope visual field, pass the celioscope stitching knotter of line, stitching, knotting and trimming function in intraperitoneal maneuverability ground, so that solve the various technical problems of passing line, stitching, knotting and trimming that in body cavity, to carry out maneuverability in the laparoscopic surgery.
