Description

Multifunctional electrocoagulation dissecting flushing and sucking device for laparoscope

Technical Field

The utility model relates to a dash and inhale the ware, specifically be a multi-functional electricity of peritoneoscope is congealed and is dissected towards inhaling ware, belong to medical equipment technical field.

Background

The most common instruments in laparoscopic surgery are two pieces of operating instruments, namely an electrocoagulation hook and a suction apparatus, and bleeding is inevitably encountered during the operation. At the moment, the hematocele at the bleeding part is generally sucked clean by a suction apparatus, then the suction apparatus is pulled out immediately, an electrocoagulation hook is inserted, and the electrocoagulation hemostasis is carried out after accurate positioning. However, in case of bleeding, except for a few of oozing blood with a slow bleeding speed, the blood vessel is often broken under most conditions, at the moment, the bleeding is fast, particularly, the bleeding of an artery is large in bleeding amount and fast in speed, once the aspirator is moved away, the electrocoagulation hook is not inserted and positioned, the bleeding part is covered by accumulated blood instantly, the visual field is not clear, the bleeding point cannot be positioned accurately, and then the electrocoagulation hemostasis cannot be performed effectively, quickly and accurately. In this case, the suction apparatus can be used again to repeatedly suck blood, resulting in an increase in blood loss. Many physicians now blindly coagulate in the blood when the field of vision is obscured, causing damage to surrounding visceral tissues and even burning through surrounding large blood vessels causing catastrophic hemorrhage that endangers patient life and often requires a laparotomy to treat hemostasis.

In the existing products, a device combining an electrocoagulation hook and an aspirator is provided, but the largest problem of the related products is that the electrocoagulation hook at the head end cannot retract into the aspirator, so that the aspirator in the products can only play a role in sucking smoke but cannot play a very important and common operation manipulation of the traditional laparoscopic aspirator, such as scraping, sucking, jacking, and the like, thereby greatly reducing the practicability and operability of the related products.

In general, in laparoscopic surgery, it is often necessary to perform dissection operations in a very narrow space, and it is often only possible to accommodate 1-2 operating instruments, in addition to the necessary viewing lens.

Meanwhile, the head end electrocoagulation structure is an electrocoagulation hook, has small contact area and high accuracy, and is particularly suitable for fine operation and hemostasis operation under the conditions of narrow visual field and high-risk complex anatomy of laparoscopic surgery.

It is bleed to directly support the point of bleeding to attract after becoming conventional aspirator with flexible electricity congeals hook 1 withdrawal, the automatic flow of attracting of angle control of the 8 knobs of three-way valve of while adjustment, can attract automatically and bleed and keep art wild clear and can also avoid losing the operating space because the too big pneumoperitoneum pressure that leads to of attraction flow leads to, need not to remove or take out the apparatus after the attraction control bleeds, can singlely manually release electricity congeals the hook and directly carry out electricity and congeals hemostasis operation to the point of bleeding with the thumb, this moment because art wild is clear, and uncontrollable when having avoided changing the apparatus bleed and need not the secondary location, electricity congeals hemostasis very accurate, high efficiency, and can avoid because the art wild is unclear and the blind electricity that leads to congeals the injury surrounding internal organs and the electricity that the hematocele leads to congeals efficiency.

As shown in fig. 1(c), in the flushing and sucking mode, the rotating sleeve ring 401 of the telescopic rotator 4 is pushed to drive the rotating gear 402 clamped in the inner concave toothed ring 403 to move, and further drive the telescopic electrocoagulation hook 1 fixedly connected with the rotating gear 402 to move, so that the head end of the telescopic electrocoagulation hook is completely retracted into the aspirator, at this time, the elastic fixture block 404 on one side of the telescopic rotator 4 is clamped in the limiting groove 405 on the rearmost end to fix the front and back positions of the telescopic rotator 4, the three-way valve 8 selectively opens or closes the negative pressure suction, the negative pressure system 10 can be communicated with the external water pump 12, the damage caused by the mistaken hooking of the tissue structure at the head end of the telescopic electrocoagulation hook 1 during the operation of the aspirator is avoided, the three-way valve is adjusted to selectively open or close the negative pressure suction, or the water pump is selectively connected for flushing, and the state is mainly used for blunt dissection and flushing and sucking the sero, the head end electrocoagulation structure is completely retracted into the aspirator, can be seamlessly converted into the traditional irrigation aspirator, and can use very important and common operation methods of scraping, sucking, jacking, and the like without worrying about damage because the head end is round and blunt.

The working principle is as follows: when the multifunctional electrocoagulation dissecting flushing and sucking device is used, the rotating ring 401 of the telescopic rotator 4 can be pushed forwards to drive the rotating gear 402 clamped in the concave toothed ring 403 to move, and then the telescopic electrocoagulation hook 1 fixedly connected with the rotating gear 402 is driven to move and extend out, and the rotating gear 402 can be driven to rotate by rotating the rotating ring 401 of the telescopic rotator 4, so that the electrocoagulation hook can be adjusted by rotating 360 degrees. When bleeding occurs, the right index finger can be used for poking back the rotating lantern ring 401 of the rotator 4 immediately, the telescopic electrocoagulation hook 1 is hidden in the suction tube 3, the traditional laparoscopic aspirator is changed into the laparoscopic aspirator for sucking accumulated blood, if the bleeding speed is not fast, the right index finger can be used for pushing out the rotating lantern ring 401 of the rotator 4 forwards after the wound surface accumulated blood is sucked completely, the electrocoagulation hook is used for accurately stopping bleeding, if the bleeding speed is fast, the telescopic electrocoagulation hook 1 is fixed at the suction pipe opening, and the accurate electrocoagulation stopping bleeding is performed during suction.
