Description

Auxiliary compression closing device for operation incision lymphatic fistula Technical Field The invention relates to the technical field of medical surgical auxiliary instruments, in particular to an auxiliary compression closing device for surgical incision lymphatic fistula. Background Common clinical routine surgery such as thyroid cervical lymph node cleaning, breast axillary lymph node cleaning, inguinal lymph node cleaning, chest and abdomen surgery and the like, post-operation lymphatic fistula is a common serious complication of the surgery, can cause adverse events such as lymphatic fluid leakage, incision infection, hypoproteinemia and the like, and remarkably prolongs the hospitalization period of patients. The operation type needs to clean the lymph nodes of the supraclavicular fossa, the armpit, the inguinal canal, the chest and abdomen and the like, the damage of the lymphatic vessels in the operation, especially the tiny lymphatic vessels, is unavoidable, and the complete ligation and closure are difficult, thus being the core cause of the high incidence of the postoperative incision lymphatic vessel fistula. At present, the clinical practice adopts modes such as sand bag compression, cotton pad compression, elastic bandage binding and the like to compress lymphatic vessels so as to prevent and treat lymphatic vessel fistula, and the prior art has the following core defects: 1. For shallow lymphatic vessel, shallow lymphatic vessel downside is thicker muscle and other soft tissues still, and current compression mode is when carrying out the pressurization to operation incision position, and the thicker tissue of lymphatic vessel downside can disperse pressure, leads to blocking effect relatively poor to the lymph liquid, and the closure time of lymphatic vessel broken end is longer, is unfavorable for the healing of operation incision. 2. The existing compression mode can only realize in-vitro large-area uniform compression, cannot realize targeted accurate compression aiming at lymphatic injury sites and enrichment areas, cannot effectively close deep and intensive micro lymphatic injuries, and has compression loss in core risk areas. At present, no accurate targeting closing special device for lymphatic vessel broken ends exists clinically, and the core pain point in the prior art cannot be solved, so that development of corresponding instruments is needed to meet clinical requirements. Disclosure of Invention In view of the above, the present invention aims to provide an auxiliary compression closing device for surgical incision lymphatic fistula, which solves the technical problem of poor lymphatic occlusion effect when the conventional compression method is adopted to compress the surgical incision position. The invention is realized by the following technical scheme: The utility model provides an auxiliary oppression closing device of operation incision lymphatic fistula, includes pjncture needle, extrusion piece and pressure portion of holding, the pointed end of pjncture needle is used for following the direction that is on a parallel with operation incision length from lymphatic vessel one side and pierces patient's skin to after passing the tissue of lymphatic vessel downside, outside the opposite side of lymphatic vessel is worn out to skin, the both ends of pressure portion of holding are used for installing in the both ends of pjncture needle after the pointed end of pjncture needle is worn out to skin from the opposite side of lymphatic vessel, pressure portion of holding still is used for holding extrusion piece towards pjncture needle direction to make extrusion piece and pjncture needle centre gripping the tissue between pjncture needle and the skin in opposite directions. The invention has the beneficial effects that: When the auxiliary compression closing device for the operation incision lymphatic fistula is used, the extrusion block and the puncture needle can play a clamping role on tissues around the lymphatic vessel, and when the tissues around the lymphatic vessel are clamped through the extrusion block and the puncture, the tissues on the upper side and the lower side of the lymphatic vessel are thinner, so that the clamping force can well act on the lymphatic vessel, the blocking effect on the lymphatic fluid can be improved, the closing time of the broken end of the lymphatic vessel is shortened, and the healing of the operation incision is facilitated. And the binding winding mode is not needed, and the influence on the smoothness of the blood of a patient caused by the too tight binding winding is avoided. Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objects and other advantages of the invention may be realized and obtained by
