A retractor for clinical surgery

Abstract

The invention provides a retractor for clinical surgery. The retractor for surgical clinical operations includes a Y-shaped frame, a push assembly and an injection mechanism, and retractors are installed on both sides of the Y-shaped frame, and the retracted parts include a curved rod and a traction hook. One end of the rod is inserted into the installation groove opened at the connecting end of the Y-shaped frame and connected by the pin shaft rotation, and the bottom of the other end of the curved rod is fixedly fitted with several traction hooks distributed equidistantly. The surface is provided with an excessive arc surface, the pushing assembly for adjusting the distance between the two groups of retractors is installed on the Y-shaped frame, and the injection mechanism for sterilizing the patient's affected part is installed on the Y-shaped frame. The retractor device for clinical surgery provided by the present invention presses the pressure plate so that the liquid medicine in the injection cylinder is discharged into the liquid discharge nozzle through the hose, and the liquid medicine is discharged from the liquid discharge nozzle, and the liquid medicine rolls down with the traction hook. On the one hand, the traction hook is just sterilized, and on the other hand, the safety of the patient's retracted wound is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a retractor for clinical surgery. Background technique [0002] Surgery is a subject of modern medicine, which mainly studies how to use surgical methods to remove the pathogens of patients, so that patients can be treated. Surgery, like all clinical medicine, needs to understand the definition, etiology, manifestations, diagnosis, staging, treatment, and prognosis of diseases, and surgery pays more attention to the indications for surgery, preoperative evaluation and care, surgical techniques and methods, postoperative Care, surgical complications and prognosis and other issues related to surgery. [0003] In clinical surgery, when operating on the patient's skull or spine, it is usually necessary to use a retractor to retract the patient's skin and muscle tissue to provide space for the operation.

Problems solved by technology

[0003] In clinical surgery, when operating on the patient's skull or spine, it is usually necessary to use a retractor to retract the patient's skin and muscle tissue to provide space for the operation. A large space affects the exposure of the surgical field during surgery. In neurosurgery, effective and sufficient exposure of the surgical field is one of the key conditions for the success of the entire operation. In order to improve the exposure of the surgical field, we can proceed from two aspects , on the one hand to increase the size of the pulling opening, on the other hand to reduce the space occupied by the retractor when pulling

[0004] Most of the traditional retractors use two-point retraction, which leads to unstable retraction of the knife edge, and brings relatively great pain to the patient. The retractor can only perform simple traction, which makes it difficult to safely handle the patient's wound
