Description

Technical Field

[0001] This utility model relates to the technical field of fan-shaped retractors for pediatric abdominal cavity, specifically a fan-shaped retractor for pediatric abdominal cavity. Background Technology

[0002] As we all know, with the advancement of technology, the operational efficiency of medical devices for treating patients has become increasingly sophisticated. When performing abdominal surgery on children, retractors are needed to cover the intestines and other tissues in the abdominal cavity to expand the surgical field and facilitate subsequent surgical procedures. Traditional abdominal retractors are single-wing retractors. When the surgical area to be exposed in the abdomen is large, single-wing retractors cannot meet the surgical requirements well. Fan-shaped retractors are often used to simultaneously insert into the surgical incision for pushing and pulling traction.

[0003] Existing fan-shaped retractors cannot quickly adjust the number of retractors according to usage needs, which is inconvenient in use. Therefore, we propose a fan-shaped retractor for pediatric abdominal cavity to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model discloses a fan-shaped retractor for pediatric abdominal cavity use, comprising a large toothed plate 1, a main retractor 2 at the bottom of the large toothed plate 1, several sliding adjustment grooves 3 in the middle of the large toothed plate 1, a fixing bolt 4 in the middle of the large toothed plate 1, several detachable retractors 5 in the middle of the fixing bolt 4, and a fixing hole 6 in the middle of each detachable retractor 5. The fixing hole 6 mates with the fixing bolt 4 in a sliding fit, allowing the fixing hole 6 to slide along the fixing bolt 4. A positioning groove 7 is provided at the rear of each detachable retractor 5, and a hand-tightening fixing bolt is provided in the middle of each positioning groove 7. The positioning groove 7 of the pediatric abdominal fan-shaped pull hook facilitates the fixing of the adjustment handle 8. Each detachable pull hook 5 is provided with an adjustment handle 8 at the rear. Each adjustment handle 8 cooperates with the positioning groove 7. The cooperation between each adjustment handle 8 and the positioning groove 7 is a sliding fit, so that the adjustment handle 8 can be installed along the positioning groove 7. The large toothed plate 1, main pull hook 2, sliding adjustment groove 3, fixing bolt 4, detachable pull hook 5, fixing hole 6, positioning groove 7 and adjustment handle 8 are all rounded, so that the pediatric abdominal fan-shaped pull hook will not scratch the user when used. The number of pull hooks can be quickly adjusted according to the needs of use, making it more convenient to use.

[0021] In summary, this pediatric abdominal retractor allows for convenient use. The number of detachable retractors 5 required is determined based on surgical needs. The detachable retractors 5 are assembled by connecting the fixing holes 6 and fixing bolts 4. The adjusting handles 8 are then inserted into the detachable retractors 5 through the sliding adjusting groove 3 via the connection between the adjusting handles 8 and the positioning grooves 7. After adjusting the angles of the detachable retractors 5, the fixing bolts 4 are tightened for positioning. This pediatric abdominal retractor allows for quick adjustment of the number of retractors according to usage requirements, making it more convenient to use and resulting in better surgical outcomes.
