腹式全子宫切除术是妇科最常见手术之一,结扎子宫动脉是该手术中主要环节。由于子宫动脉在靠近子宫处其周围有较多小静脉血管,这些小血管紧贴于子宫旁侧,在缝扎血管时需避免因缝针穿破血管而引起出血。用一般止血钳钳夹子宫动脉,在合钳时可能发生个别小血管被挤出钳端之外,而该处正是进针部位,易刺破血管。为防止上述情况,我们改用鼠齿钳(组织钳)钳夹子宫动脉,并考虑到:一、子宫颈段呈管状,其肌质较韧,用鼠齿钳紧贴子宫合钳时不会夹住肌层。二、合钳时能将紧贴子宫旁的血管均夹入钳内。三、钳吻合端较止血钳宽,便于引导缝针。具体操作步骤如下:在分离膀胱及阔韧带无血管
Abdominal hysterectomy is one of the most common gynecological surgery, ligation of the uterine artery is the main link in this operation. As the uterine artery near the uterus around the more venous blood vessels around the small blood vessels close to the side of the uterus, sutured blood vessels need to be avoided due to needle penetration of blood vessels caused by bleeding. General hemostatic forceps clamp the uterine artery, in the pliers may occur when individual small blood vessels are squeezed out of the pliers side, and where the needle is the site, easy to pierce the blood vessels. In order to prevent the above situation, we use the rat’s forceps (tissue forceps) to clamp the uterine artery, taking into account: First, the cervix was tubular, and its muscle tough, with the rat to clamp the uterus clamping forceps will not Clamp muscle. Second, the clamp can be close to the uterus next to the blood vessels are caught in the clamp. Third, the anastomosis end of the hemostat clamp wide, easy to guide the needle. Specific steps are as follows: in the separation of the bladder and broad ligament without blood vessels
