Problems solved by technology
[0003] In the prior art, although the retractor is repeatedly sterilized when in use, it still has a relatively large potential safety hazard. If the retractor is replaced as a whole, the cost is high, and when the retractor hooks the position of the incision, it only passes through the gap between the incision and the incision. The friction between them hooks the incision, which is easy to slip and not stable enough

The invention discloses an operation drag hook for urinary surgery and a using method, and belongs to the field of medical instruments, the operation drag hook for urinary surgery comprises a hook body, a through hole is formed in the hook body, a negative pressure hole is formed in the side wall of the hook body, the hook body comprises an installation part and a contact part, the through hole is located in the installation part and the contact part, and the negative pressure hole is located in the contact part. The use method of the surgical retractor for the urinary surgery comprises the following steps that S1, the contact part abuts against an incision of a patient, and then the clamping part is shifted to clamp the incision. By means of the negative pressure suction device, cross infection can not be caused when a new contact part is used, safety is high, the whole contact part does not need to be replaced, only the contact part needs to be replaced, cost is low, an incision is sucked in a negative pressure mode, and stability is higher.
Description
technical field [0001] The invention relates to the field of medical instruments, and more particularly, to a surgical retractor for urology surgery and a method of using the same. Background technique [0002] The main treatment areas of urology are: various urinary stones and complex kidney stones; kidney and bladder tumors; prostatic hyperplasia and prostatitis; inflammation and tumors of the testicular epididymis; testicular spermatic hydrocele; various urinary tract injuries; Department of congenital malformations such as hypospadias, cryptorchidism, hydronephrosis caused by stenosis of the ureteropelvic junction and so on. [0003] In the prior art, although the retractor is repeatedly sterilized in use, it still has a large potential safety hazard, and if the retractor is replaced as a whole, it will result in higher cost, and when the retractor is hooked at the position of the incision, it only passes through the gap between the incision and the incision. The fricti...
