Technical Field

The utility model relates to the technical field of medical equipment, in particular to a tissue traction hook for laparoscopic surgery.

Background

Laparoscopic surgery has become a surgical mode which is willing to be accepted by doctors and patients, the surgical operation process is completed in an abdominal cavity, and often an operation clamp is introduced to assist in pulling tissues by inserting a trocar through the abdominal wall, so that the smooth operation is facilitated, however, the placement of the trocar and the operation clamp not only aggravates the injury of the patients and prolongs the operation time, but also increases the scars of the abdominal wall after the operation of the patients. Therefore, the trocar-free tissue traction device suitable for laparoscopic surgery has important significance in the laparoscopic surgery treatment process.

Chinese patent document CN206197988U discloses a tissue retractor for laparoscopic surgery, which has a simple structure, is convenient, safe and reliable to use, and the surgeon can change the position of the retractor at any time according to the needs, thereby achieving the purpose of optimally retracting and exposing the operative field and shortening the operation time. The use of the device replaces a method for pulling tissues by operating forceps, thereby not only reducing the use amount of trocars and the injury of patients, but also reducing the labor amount of medical staff;

however, the technical solution disclosed in the above patent has the following disadvantages:

the pull wire is fixed knot structure, can not adjust the length of pull wire according to actual conditions when carrying out laparoscopic surgery, and the pull wire overlength or short enough can influence laparoscopic surgery's normal clear, consequently need be equipped with the tissue of multiple different specifications, different length pull wire and pull the hook to use cost has been improved.
