Technical Field
The utility model relates to the technical field of medical equipment, in particular to a liver suspension device for laparoscopic surgery.
Background
With the continuous development of clinical medicine, the invention of the laparoscope enables the revolutionary improvement of the common surgical treatment. Laparoscopic surgery is gradually replacing traditional surgery with the advantages of less trauma, more delicate procedures, etc. The operating instruments of the laparoscopic surgery are all cylindrical with the diameter of about 5mm, the wound is small, and the space in the abdominal cavity is more obviously narrowed through micro operation. Sometimes, the liver can block the operation visual field to interfere the operation, and at the moment, the liver needs to be dragged, lifted and suspended, the prior art uses the tip of an operation instrument to lift or push the liver, or uses a suture line to bypass the visceral surface of the liver, and the two ends of the suture line pass through the abdominal wall and then drag the liver on the body surface, the former has the defect that the operation instrument is not fixed, so the position of the liver cannot be well fixed, meanwhile, the operation instrument is occupied, and the sharp instrument is easy to stab the liver, which is not beneficial to the operation of doctors; the latter has the defects that the traction needle is possibly unstably clamped in the abdominal cavity, viscera and tissues in the abdominal cavity are easily pulled to be injured, the traction effect of a single suture on the liver is poor, the operation requirement cannot be well met, and in addition, the single suture easily causes the injury of the liver in the traction process because the liver is soft and tender.
In view of the above, for example, patent CN203436352U, "a liver suspender for laparoscopy" and patent CN205672086U, "a liver suspension sheet for laparoscopic surgery" both use a diamond-shaped net which can be stretched and opened as a suspension carrier to suspend the liver, but in the above patents, the suspension carrier has a small contact area with the liver, and thus there is a problem of insufficient contact, and particularly, in the former patent, both sides of the liver cannot be effectively supported during suspension, and in the case of traction suspension, a medical worker often pulls an adjustment traction wire to support the suspension carrier, and in the case of manual operation, there is inconvenience, and in the operation process, once the patient is replaced, a new medical worker is difficult to maintain the current suspension effect, and there is a high possibility of secondary adjustment.
