Description

Technical Field

[0001] The present invention relates to the technical field of practical laparoscopic instruments, and in particular to a quantifiable multi-angle practical laparoscopic instrument. Background Art

[0002] Laparoscopic surgery, also known as minimally invasive surgery, is a technique developed in the late 1950s. During laparoscopic surgery, surgical technicians can manipulate the patient's internal tissues with their hands away from the surgical area. Laparoscopic instruments are inserted into the patient's body through small skin incisions and tools at both ends are controlled by the surgeon, who sutures the wound.

[0003] Existing laparoscopic instruments generally include a handle, an instrument rod, and an instrument head. The handle can be divided into a handle body and a rotating wheel. The handle body and the rotating wheel can rotate relative to each other, and the instrument rod is fixed to the rotating wheel. This can make laparoscopic surgical instruments more flexible to use. However, for pre-bent rigid laparoscopic instruments, the instrument rod needs to be twisted during operation, and the instrument can only be rotated 360 degrees. It is difficult to expose the posterior wall and blood vessels or tissues with more tricky angles to achieve relevant treatment operations. Therefore, it is necessary to invent a quantifiable multi-angle practical laparoscopic instrument to solve the above problems. Summary of the invention
