Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology and solve the problems that the operation of the retractor is too cumbersome, repeated retraction causes multiple injuries to the subcutaneous tissue, the repeated operation of the retractor seriously prolongs the operation time and the injection of normal saline cannot be more convenient and quick. A minimally invasive laparoscopic retractor proposed by the invention

The invention belongs to the technical field of medical appliances, and specifically discloses a minimally invasive laparoscopic retractor. The minimally invasive laparoscopic retractor comprises a sleeve ring, a conductor, a support tube and a movable tube; the conductor is composed of a plurality of conduction rods and a conduction ring; the support tube is composed of a plurality of support rods and a support ring; the lower end of each of the support rods is fixedly connected with a rubber block; a cavity is formed inside each of the rubber blocks; two arcuate elastic pieces are fixedly connected with the interior of each of the cavity; third grooves, which are in one-to-one correspondence with sliding rods, are formed on a surface of the movable tube; second guide grooves communicatethrough the third grooves; ejector cores are connected with the interior of the third grooves in a sliding way; and the ejector cores are fixedly connected to the inner walls of the second guide grooves by evenly distributed springs. The minimally invasive laparoscopic retractor is capable of avoiding influence on surgery by effectively preventing closure of an opening during operation, thereby reducing the probability of secondary injury to subcutaneous tissue caused by medical instruments during the operation; moreover, the minimally invasive laparoscopic retractor is also capable of allowing more quickly and conveniently cleaning of a patient's wound with physiological saline.
Description
technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a minimally invasive laparoscopic retractor. Background technique [0002] The retractor is used to retract the tissue, expose the surgical field, and facilitate exploration and operation. Laparoscopic surgery, also known as minimally invasive surgery, is becoming an increasingly popular surgical method. The number of surgeons graduating each year with advanced minimally invasive training continues to increase, which means that the number of minimally invasive abdominal cases will also increase. [0003] The use of a retractor is essential during abdominal surgery. It is used to retract the skin and subcutaneous tissue so that the internal organs are exposed to the doctor's field of vision to facilitate the operation. [0004] Retractors in the prior art are mainly divided into two types: hand-held retractors and automatic retractors. There are various specifications...
