Problems solved by technology

The current surgical retractor requires a large incision to enter the abdominal cavity, and the retraction operation is not easy to control
Originally, surgery is a very difficult job for the medical staff, especially for the operation in a place with a small space. Stretching and maintaining it for a long time puts forward higher requirements on the physical strength of the medical staff, and also increases the difficulty of the surgical operation. Maintaining the stretched state through the manual operation of the medical staff also reduces the consistency and safety of the operation. For this reason we introduce a distraction device for kidney transplantation

Abstract

The invention discloses a spreading device for the renal transplantation surgery. The device comprises a base, a push handle is arranged on the base, and an automatic retractable rod is fixedly connected to the base; a horizontal rod is connected to the upper end of the automatic retractable rod through a fixing connection block, a driving case is arranged at the left end of the horizontal rod, and two spreading plates are arranged at the lower side of the right end of the horizontal rod. The spreading device for the renal transplantation surgery is ingenious in structural arrangement and reasonable in distribution, a motor drives a first transmission rod to rotate, the first transmission rod drives a lead screw to rotate, the lead screw rotates to drive two sleeving blocks on the lead screw to be closed to or away from each other, the spreading plates are driven to be close to or away from each other accordingly, and the effect of spreading wounds is achieved. Small-sized shadowless lamps are arranged at the lower ends of the inner sides of the spreading plates, swishes are arranged at the upper ends of the spreading plates, storage batteries are arranged in the spreading plates, the small-sized shadowless lamps are connected with the switches and the storage batteries, during surgery, the further illumination effect can be achieved for surgery doctors, and the surgery can be more accurate and errorless.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a distraction device for kidney transplantation. Background technique [0002] Kidney transplantation is the transplantation of kidneys from healthy people to patients with kidney disease and loss of kidney function. It is an effective means of treating chronic renal failure. Kidney transplantation can be divided into autologous kidney transplantation, allogeneic kidney transplantation and xenogeneic kidney transplantation due to different sources of kidney donors. It is customary to refer to allogeneic kidney transplantation as kidney transplantation for short. The other two types of kidney transplantation are labeled as "autologous" or "xenogeneic" kidney transplantation to distinguish them; during kidney transplantation, the wound needs to be propped open. The incision required for the current operation to enter the abdominal cavity with a retractor is relatively larg...
