However, taking this method of enlarging the wound surface increases the probability of surgical infection, which is not ideal for patients and surgeons
[0004] Furthermore, in surgery, when the cross-section of the retractor cannot completely cover the area to be operated on, it is necessary to replace the retractor with a larger cross-section. Retractors will complicate the procedure and will take significantly longer
[0005] In addition, the retractor cannot measure the penetration depth when entering the fine tissue area, which will also bring unnecessary trouble to the operation to a certain extent.

Embodiment
[0029] Such as Figure 1-6 A retractor applied to delicate tissues is shown, comprising: a right half retractor 1, a left half retractor 2, an elastic film 3 and a bolt 4; the right half retractor 1 includes: a right retractor Part 11 , right introducing part 12 and right half handle 13 ; the left half retractor 2 includes: left retracting part 21 , left introducing part 22 and left half handle 23 .
[0030] The positional relationship of the above-mentioned parts is: the right introduction part 12 is located at the bottom of the right half retractor 1, and the right retraction part 11 is located above the right introduction part 12; the upper end of the right half retractor 1 is provided with Right half handle 13; said left introduction part 22 is located at the bottom of left half retractor 2, and left retractor part 21 is located above left introduction part 22; said left half retractor 2 upper end is provided with left half handle 23. The right half handle 13 and the left...

The invention discloses a retractor applied to fine tissues, which comprises a right half retractor and a left half retractor. The upper end of the right half retractor and the upper end of the left half retractor are movably connected; a right half handle is arranged at the upper end of the right half retractor; a left half handle is arranged at the upper end of the left half retractor; the right half handle and a left traction part are positioned on the same side and connected through a bolt; and the distance between the right half handle and the left traction part is adjusted through the bolt. The retractor is not required to be changed in an operation, reduces the operation complexity, quickens the operation progress, effectively avoids sprain of fine tissues, reduces the probability of complicating diseases, improves the success ratio of operation, enlarges the visual range during the operation, and simultaneously is convenient and simple to use.
Description
technical field [0001] The invention relates to a medical device, in particular to a retractor for fine tissue surgery and an application method thereof. Background technique [0002] In surgery, in the process of targeting the delicate subcutaneous tissue, such as brain tissue, breast tissue, deep abdominal wall tissue, etc., the traditional surgical retractor is a thin, hard steel or other metal alloy belt. Has steep or well-defined edges and has limited surface area. The usual structural form is a simple strip of sheet metal consisting of metal strips, which can be bent by hand and whose surface typically contours on the brain after a few minutes. These conventional retractors may be introduced into or along the surface of delicate tissue during surgery and then pulled vigorously to separate or elevate the delicate tissue. The method allows a target volume to be illuminated and visualized for performing a surgical procedure. However, delicate tissues are soft and easil...
