Energy type hemorrhoids cutting anastomosis device

Abstract

The invention discloses an energy type hemorrhoids cutting anastomosis device. The energy type hemorrhoids cutting anastomosis device comprises an upper electrode assembly, a lower electrode assembly, a knife cushion ring, a cutter part, a straight push pipe, a cocking handle assembly, a lower electrode outer sleeve, a handle, an adjusting knob assembly, a lead screw assembly and a high frequency power supply circuit module. The cutter part is fixedly connected with one end of the straight push pipe, and the other end of the straight push pipe is movably connected with one end of the cocking handle assembly. The upper electrode assembly is matched with the lower electrode assembly. Both the upper electrode assembly and the lower electrode assembly are connected to the high frequency power supply circuit module. The cutter cushion ring is matched with the cutter part. According to the energy type hemorrhoids cutting anastomosis device, one electrode block or two or more electrode blocks can be selected for conducting coagulation and closing on tissue according to the haemorrhoids symptoms in an operation, the rest of the tissue where coagulation and closing are conducted are cut off, by means of the operation performed through the method, the coalesce speed of a wound is effectively increased, the rehabilitation cycle of a patient is shortened, the phenomena that blood oozing and blooding happen to the sutured wound can be better eliminated, and meanwhile some post-operation complications are reduced.

Description

technical field [0001] The invention relates to an energy type hemorrhoid cutting and anastomosis device, which belongs to the field of medical instruments. Background technique [0002] At present, anorectal hemorrhoids are commonly called hemorrhoids, which are common and frequently-occurring diseases unique to human beings. According to relevant census data, the incidence rate of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, and among them, internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. Both men and women can get the disease, the incidence rate of women is 67%, and the incidence rate of men is 53.9%. It can occur at any age, and it will gradually worsen with age, so there is a saying that "nine out of ten people have hemorrhoids". General surgical treatment includes traditional operations such as ligation, rubber band ligation, hemorrhoidectomy and anastomosis. At present, well-know...

Problems solved by technology

At present, well-known medical manufacturers at home and abroad, including American Foreign Affairs, Johnson & Johnson, Kandi, Frankman, etc., all produce traditional mechanical hemorrhoidectomy staplers. It is easy to cause bleeding at the anastomosis and bleeding again at the anastomosis within a period of time after the operation. If it is not detected and treated in time, it will lead to swelling and ulceration of the suture wound, the consequences will be very serious, and the success rate of the operation is low.

And the operation after the above method, the operation time is long, the wound healing period is long, the pain brought to the patient and the operation risk are high

The traditional mechanical stapler uses two rows of annular nail slots (the number is 30 and 32 pieces) that intersect inside and outside to make the staples form a B shape in the nail slots. Processing accuracy, material strength of plastic parts and manufacturing process of plastic parts are high, and the assembly size and position of parts in the assembly process are difficult to control, especially in the mass production process, once a part has quality problems , it will directly affect the forming quality of the staples, which will eventually lead to unreliable sutures during the operation, serious suture failures, and high surgical risks; the traditional mechanical stapler uses the firing handle to drive the pusher piece, the pusher The staples then push the staples in the staple bin, and the staples penetrate the tissue to form a B-shape in the anvil seat, and at the same time use the ring knife to suture and remove the excess tissue; because it sutures and cuts The action is carried out at the same time, so the force required during the firing process is relatively large, so there are requirements for the operator's skills and hand strength. Once the fire is fired, the operator's hand position and strength cannot be grasped. Well, it is easy to cause the firing to not be in place, and eventually lead to the failure of the operation, and the risk of the operation is extremely high
