Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a finger cot separator. Background Technology

[0002] Minimally invasive laparoscopic surgery requires the initial creation of a pneumatic cavity to provide operational space, as well as a puncture card to guide the procedure. Creating both the pneumatic cavity and the puncture card necessitates incising the skin, lifting adjacent skin, fat, muscle, pleura, and peritoneum, and then directly puncturing the chest and abdominal wall with a needle or puncture card. This is particularly challenging for obese patients, as it makes lifting the chest and abdominal wall difficult, or during secondary surgeries with severe adhesions in the chest and abdominal cavities, increasing the risk of damage to surrounding organs and bleeding. In conventional open surgery (especially deep organ and tissue surgeries), tissue dissection in blind spots is typically performed using the blunt force of the experienced surgeon's fingers, which not only increases the difficulty but also the risk of complications.

[0003] Based on an agricultural approach, a finger cot for picking fruits and vegetables and the existing finger cot scalpel, if used in surgery, can cut the abdominal wall. However, without protective devices, the sharp blade may still damage surrounding organs during operation. Small bleeding can obstruct the field of vision and affect the surgical operation. It cannot be handled immediately with one hand, and the fingers wearing the finger cot lack precise tactile sensation, which will affect the surgical procedure. Summary of the Invention
