Description
Technical Field
The utility model relates to a single port peritoneoscope operation appurtenance specifically is an apparatus passageway that is used for simple and easy single port peritoneoscope platform of getting into way, belongs to medical instrument technical field.
Background
The single-port laparoscopic surgery is a new minimally invasive surgery in recent years, a single-channel multi-channel laparoscopic instrument is placed in one umbilical incision for surgery, and the skin fold of the umbilical region can cover the scar of the incision, so that the single-port laparoscopic surgery has a satisfactory cosmetic effect and can relieve postoperative pain. Due to the adoption of single-hole operation, the single-hole laparoscopic surgery has higher requirements on the surgical skill of doctors and needs a special instrument access platform. At present, mainstream single-port laparoscope access platforms in the market are all disposable consumables, the price is about 3000 yuan, the patient is undoubtedly brought with great economic burden, the consumable occupation ratio of hospitals is increased, and therefore each hospital starts to try to use the self-made simple single-port laparoscope access platform. The simple single-port laparoscope access platform is generally made of an incision protection sleeve and medical gloves, the incision protection sleeve is placed in an umbilical incision of a patient, cuffs of the medical gloves are connected with the incision protection sleeve, the tail ends of all the finger sleeves of the medical gloves are cut to form openings, corresponding instrument channels are placed in the openings and are bound through silk threads, and the simple single-port laparoscope access platform can be constructed.
In the homemade laparoscope single-hole multi-channel device disclosed in the chinese patent CN201620783623.5, the conventional laparoscope sheath card is directly connected with medical gloves to serve as an instrument channel, but the volume of the sheath card is large, so that the originally narrow operation space becomes narrower, and the operation difficulty is increased.
In the access channel of the single-port laparoscope disclosed in CN201820108832.9, the instrument access tube is used as the instrument channel, and the instrument access tube can directly use a temporarily cut disposable suction tube tip, which is widely used clinically in hospitals, because the sealing performance between the channel and the instrument is not good when the suction tube tip is used as the instrument channel, and the air pressure in the glove is liable to flow back through the instrument channel to cause air leakage when the instrument is used and passed in and out the channel, the method in the third embodiment of the patent is generally used clinically, that is, a flap with an opening at the front end made of a fingertip part of the medical glove is bound at the inner side end of the suction tube insertion glove, and the air pressure in the glove is used to press the flap to form a certain seal to control air leakage. However, such an instrument channel still has a large defect, and mainly when a flap is manufactured clinically, the requirement for controlling air leakage cannot be met due to the influences of the length, the size, the opening shape and other factors of the flap, and the front end of part of the surgical instrument is sharp, so that the flap valve is possibly damaged when the surgical instrument channel enters or exits, and the risk that the damaged and broken flap valve fragments enter the abdominal cavity of a surgical patient exists. Therefore, it is desirable to provide a small, airtight and safe instrument channel for accessing instruments for such a simple laparoscopic access platform.
