Disposable adjustable hand-assisted device for peritoneoscope

Abstract

The disposable adjustable laparoscopic hand aid mainly consists of an arm barrel, an arm strap, an outer ring, an outer ring caliber adjustment device, a spreading device, an inner ring, an inner ring caliber adjustment device and gloves. The arm barrel is fixed on On the outer side of the outer ring, there is an arm strap at the top; the inner ring is fixed on the inner side of the outer ring; between the inner and outer rings is a cylindrical membrane; the inner and outer rings are elastic rings, and are equipped with inner and outer ring diameter adjustment devices; Turn over and connect to the outer ring. The disposable laparoscopic adjustable hand aid is provided with elastic inner and outer rings and an inner and outer ring caliber adjustment device, which can cooperate with each other to adjust the inner and outer ring calibers. Therefore, the caliber of the inner and outer rings of the hand aid can be adjusted according to factors such as the operating range, surrounding organs, surgical incision, operator's arm and palm, to improve surgical operability; the mouth of the glove is everted and fixed to the outer ring to meet the sealing requirements and Sterile requirements; the expansion device can assist in exposing the target organs and reduce the interference of surrounding organs; it can protect the abdominal wall incision and reduce the wear and tear on the incision.

Description

technical field [0001] The present application relates to a medical device, in particular to a hand aid with adjustable caliber for laparoscopic surgery. Background technique [0002] In recent years, minimally invasive surgery, which has the advantages of less trauma, faster recovery, less pain, and high cure rate, has developed rapidly. Laparoscopic technology, as a representative of minimally invasive surgery, has been widely used in surgical treatment. Hand-assisted laparoscopy is a new type of minimally invasive surgery developed under traditional laparoscopy. It not only enables surgeons to operate in a familiar three-dimensional space, but also has higher flexibility and operation compared with surgical instruments. Features: can stretch organs to assist in exposure; can blunt dissection; can determine the root position of blood vessels through vascular pulsation; can find lymph nodes by palpation to assist in lymph node dissection; can accurately resect diseased inte...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the deficiencies in the prior art, this application intends to provide a new type of laparoscopic adjustable hand aid, which can facilitate the operation of the operator's arm while ensuring a certain degree of airtightness and pneumoperitoneum pressure during the operation. The adjustment can avoid poor blood circulation, numbness and discomfort of the arm due to long-term movement restriction, increase the operability of th
