Telescopic draw hook for kidney transplantation operation

Abstract

The invention discloses a telescopic draw hook for a kidney transplantation operation. The telescopic draw hook comprises a U-shaped base, a first threaded rod, a rotating handle, an abutting block, a vertical supporting rod, a bearing, a second threaded rod, a first bevel gear, a second bevel gear, an adjusting handle, an adjusting outer rod, a first spring, an adjusting inner rod, a threaded sleeve, a supporting transverse rod, an operation drag hook body, a limiting rod, a limiting block, a second spring, a sliding plate, a sliding block, a guide pipe, a hook head, an air bag and a liquid storage box. The limiting protrusion is arranged on the adjusting handle so that the adjusting handle can be conveniently limited and fixed, the rectangular grooves are formed in the horizontal end of the operation drag hook body so that the operation drag hook body can be conveniently adjusted in the horizontal direction, and the one-way valve is fixedly arranged on the guide pipe so that hematocele can be prevented from flowing back; the guide pipe is provided with two sections of flexible hoses between the sliding blocks, the usable length of the guide pipe can be increased conveniently, an anti-skid rubber pad is arranged on the abutting side of the abutting block, and the stability of the operation draw hook can be improved conveniently.

Description

technical field [0001] The invention relates to a surgical retractor, in particular to a retractable retractable retractor for kidney transplantation, which belongs to the technical field of medical equipment. Background technique [0002] Kidney transplantation refers to a surgical method of transplanting a kidney from a healthy donor to a recipient with kidney disease or loss of kidney function. It is the only treatment for end-stage renal disease. Normal healthy adults have two kidneys, which are located at the back of both sides of the waist and on both sides of the spine. They are close to the posterior abdominal wall and located behind the peritoneum. The kidney is half a vertebral body lower, the 12th rib on the left side obliquely crosses the middle behind the left kidney, and the 12th rib on the right side obliquely crosses the upper part behind the right kidney. From the anatomical position of the kidney, it can be found that the kidney is located behind the abdom...

Problems solved by technology

[0003] At present, ring retractors are clinically used for kidney transplantation, but ring retractors will occupy a large amount of operating space. If the renal blood vessels are short or deep, it is very unfavorable for the delicate surgical operation of vascular anastomosis, which will increase the occurrence of vascular complications. risks of

However, some existing conventional surgical retractors often have some common problems: first, most of the existing surgical retractors have fixed specifications, and the length and height of the retractors cannot be adjusted according to the actual needs in the operation, lacking certain flexibility. sex, it is more troublesome to use

Moreover, the size of the patients varies greatly, so it is difficult to completely match the retractor with the patient. Frequent replacement during the operation is often required, which increases the length of the operation and affects the smooth progress of the operation. Second, kidney transplantation is a difficult operation. For a long operation, there will inevitably be injury and bleeding during the operation of kidney transplantation. At the same time, kidney transplantation is also an operation that requires anastomosis of blood vessels and ureters, and the bleeding during the operation is usually at the lowest point in the patient's body cavity. accumulation

The hemorrhage in these operations will affect the field of view of the operation and the accuracy of the operator's operation. Usually, the operator or assistant is required to continuously use a negative pressure suction device to suck the accumulated hemorrhage out of the body cavity during the operation, but this not only increases the operator's The operation with the assistant is difficult, and the continuous contact with the suction device may also easily cause further damage to the tissue, which may also increase the risk of surgery
