Description

Basic operation simulation training device for surgical operation

Technical Field

The utility model relates to a medical science simulation teaching aid technical field especially relates to a basic operation simulation trainer of surgery operation.

Background

The basic operating skills of the surgery are many, students or medical staff need to exercise constantly and accumulate experience to grasp gradually, and in teaching, due to the limitation of factors such as risks, beginners only stay in a theoretical stage in the operation aspect, and some animals are simulated and trained at the same cost, so that the students can experience better operation, but the cost is high, and the beginners are professionally prepared.

Chinese patent publication No. CN2505942 discloses a simulated training device for basic operation of surgical operation. The device is a three-layer duplex structure simulating soft tissue, which is composed of single-layer fabrics with two different colors and a fiber layer of a middle interlayer. The designed model imitating 'stomach' and 'intestinal canal' can provide real teaching tools for students to train hemostasis, suture, anastomotic blood vessels and anastomotic after organ cutting in basic operations, but the operation of surgical operations is far more than the ones solved by the patent, because the functions are few, the possibility of realizing sufficient exercise is not great, and the practicability of the device is not strong.

The basic principle of suturing according to Baidu encyclopedia records is as follows:

(1) to ensure good apposition of the sutured wound surface or wound. The suture should be performed layer by layer, and the suture is performed according to the anatomical layer of the tissue, so that the tissue layer is tight, other tissues are not involved or sewed, residual cavities are not left, and effusion, hematocele and infection are prevented. The suture wound margin distance and the needle distance must be uniform, so the appearance is beautiful, more importantly, the stress and the shared tension are uniform and the suture is tight, and the leakage cannot occur.

(2) Note the tension at the stitch. The tightness of the ligation suture line is determined by the tight contact of the incision edges, and the suture line is not too tight, in other words, the early and late healing and the quality of the incision are not completely proportional to the tightness, and the poor healing can be caused by too tight and too loose. When the wound has tension, tension-reducing suture should be performed, and if the wound has too large defect, metastatic flap repair or skin flap transplantation can be considered.

(3) The choice of suture and needle is appropriate. The aseptic incision or the wound with light pollution can be cleaned by silk thread after being disinfected, and the wound with serious infection or pollution can be made by absorbable suture, and the anastomosis of the blood vessel should be made by selecting the non-invasive needle thread with corresponding type.

The classification of the suture and the commonly used suture methods introduce a plurality of suture methods, and no uniform classification method exists yet. Based on the involution relationship of tissues, the method is divided into three types of simple suture, eversion suture and eversion suture; each type is divided into two types of intermittent sewing and continuous sewing according to the continuity of the sewing thread during sewing; the suture is divided into horizontal suture and vertical suture according to the position relation between the suture and the tissue during the suture; sometimes, the names are obtained by combining the situations. The suture can be divided into purse-string suture, half purse-string suture, U-shaped suture, 8-shaped suture, T-shaped suture, Y-shaped suture and the like according to the shape of the suture. In addition, sutures are used for special purposes, such as tension-reducing sutures, intradermal sutures, suture hemostasis, and the like.
