Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an instrument kit for laparoscopic spleen retaining surgery.
Background
Spleen is an important lymph organ and is positioned at the left upper part of abdominal cavity, spleen belongs to reticulum skin system, is the largest immune organ of human body, increases the resistance and disease resistance of human body to bacteria and other infections, has rich spleen blood circulation, is soft and fragile in texture, and easily causes hemorrhagic shock and acute peritonitis after rupture and hemorrhage, thereby endangering the life safety of patients.
The primary means of treating spleen rupture lesions is abdominal exploration + treatment of splenectomy. In 1970, the risk of infection after splenectomy was greatly focused by general surgical specialists at home and abroad. The spleen is the largest immune organ of the human body, accounting for 25% of the whole body lymphoid tissue, and contains a large number of lymphocytes and macrophages. Macrophages proliferate when the body is subjected to trauma and critical conditions, participate in antibody-mediated systemic immune responses, are prone to cause side effects after splenectomy, and laparoscopic splenectomy was first reported in 1992, and later developed in countries around the world. The laparoscopic splenectomy is a mature minimally invasive endoscopic technique for the laparoscopic cholecystectomy, has all the advantages of small trauma, light pain, quick recovery, beautiful appearance, short hospitalization time and the like although the operation time is longer than that of the laparoscopic cholecystectomy, indicates that the laparoscopic splenectomy is the standard operation for most benign and malignant diseases of spleen in 2008 European endoscopic surgical society, almost can replace the laparoscopic splenectomy, and mainly comprises the steps of freeing ligaments around the spleen and treating the pedicles of the spleen, and can only lift the spleen with a pulling rod such as an aspirator to achieve the aim of exposing the ligaments around the spleen due to fragile and soft spleen texture and contraindication of graspers. However, the spleen is smooth in surface, so that the spleen is difficult to lift and the front end of the pulling rod is easy to puncture, bleeding is caused, and the operation progress is affected. In addition, spleen is the largest immune organ of human body and accounts for 25% of whole body lymphoid tissue, and contains a large number of lymphocytes and macrophages. When the body suffers from wounds and critical diseases, macrophages proliferate and participate in antibody-mediated systemic immune reaction, the spleen rupture excision is easy to cause side effects, including increasing infection risk, increasing disability rate, six to seven levels of disability after spleen excision, increasing postoperative platelet elevation, increasing thrombosis probability, seriously endangering the life safety of children after the removal of spleen rupture, serious illness state, extremely difficult clinical treatment, fragile spleen tissue, abundant blood circulation, extremely easy rupture and bleeding under the condition of suffering external force, spleen trauma up to 49% in abdominal trauma, impact injury, crush injury, impact injury and even bruise can lead to spleen rupture, china formulates a four-level grading method according to the spleen rupture degree, IV-level injury large blood vessel rupture, spleen must be excised, I-level rupture conservation treatment does not need operation, II-level, I-level rupture conservation treatment, The III level operation of reserving spleen is suitable for the patients with spleen rupture and superficial laceration, after the blood clots on the lacerated surface are clearly treated, mattress type intermittent stitching is carried out, or stitching binding method is adopted for hemostasis, the absorbable net is used for wrapping spleen for binding hemostasis, spleen wrapping operation treatment is carried out, the main component of the absorbable net is lactic acid, the absorbable net can be completely absorbed by human body, the absorbable net is nontoxic, antigenic and non-carcinogenic, and is completely absorbed within 3-6 months after operation, the absorbable net is considered to be the material with the best compatibility with human body at present, but the absorbable net can wrap the whole spleen except the spleen pedicel and keep a certain tension, if the wrapping is too tight, the effect of fixing hemostasis on the spleen tissue is weak, and for serious spleen trauma, the first treatment measure is to timely control spleen hemorrhage, the traditional method mainly adopts the open operation for hemostasis, but causes great damage, the bleeding amount in operation is more, postoperative complications are relatively more, and therefore a minimally invasive operation is sought The safe, effective and convenient spleen trauma treatment method is the development direction of spleen trauma treatment.
