技术领域technical field
本发明涉及一种医疗器械，尤其涉及一种两段式腹腔取物杆。The invention relates to a medical device, in particular to a two-stage abdominal object extraction rod.
背景技术Background technique
随着微创外科技术的发展，越来越多的传统开放手术得以通过腹腔镜技术实现。在腹腔镜下手术的过程中，需要将切下的组织及时从患者体内取出，尤其是恶性肿瘤的手术中，需要将某些脏器完整地从体内取出。With the development of minimally invasive surgical techniques, more and more traditional open surgeries can be realized through laparoscopic techniques. In the process of laparoscopic surgery, the resected tissue needs to be removed from the patient's body in time, especially in the operation of malignant tumors, some organs need to be completely removed from the body.
现有取物袋和操作杆大多为一体式设计，手术前操作杆前端的取物袋通过有序折叠内置于操作杆的套筒内并与内推杆连接，手术时操作杆前端通过穿刺器中央的通孔送入体内，然后内推杆将取物袋从套筒内推出，进而将肿瘤或组织装入取物袋内取出，手术后取物袋很难再人工折叠装入套筒内，只能一次性利用，取物袋连同操作杆整体被废弃，手术费用高昂，给患者带来较大的经济负担。Most of the existing retrieval bags and operating rods are designed in one piece. Before the operation, the retrieval bag at the front end of the operating rod is folded in order and built into the sleeve of the operating rod and connected with the inner push rod. During the operation, the front end of the operating rod passes through the trocar The central through hole is sent into the body, and then the inner push rod pushes the retrieval bag out of the sleeve, and then puts the tumor or tissue into the retrieval bag and takes it out. It is difficult to manually fold the retrieval bag into the sleeve after surgery , can only be used once, and the retrieval bag is discarded together with the operating rod as a whole, and the operation cost is high, which brings a greater economic burden to the patient.
此外，取物装置的套筒和内推杆之间通过摩擦环得到相对固定，但是并不能完全防止内推杆向前滑动。In addition, the friction ring is relatively fixed between the sleeve of the fetching device and the inner push rod, but the forward sliding of the inner push rod cannot be completely prevented.

During installation, the first inner push rod 11 is connected with the second inner push rod 21 through the inner bayonet 25 and the inner hook 26, and then the second inner push rod 11 is connected through the outer bayonet 23 and the outer hook 24. A sleeve 12 is connected with the second sleeve 22. During the operation, the front end of the connecting rod 2 enters the patient's body through the opening of the puncture device on the patient's body surface. The limit mechanism releases the first inner push rod 11 and pushes the first inner push rod 11 forward. , and then push the second inner push rod 21 forward, push the retrieval bag out from the second sleeve 22, so that the retrieval bag enters the abdominal cavity of the patient, and the limit mechanism can prevent the first inner push rod 11 and the second inner push rod The rod 21 slides forward; the pick-up bag is used to contain the resected lesion (tumor or diseased tissue, etc.) and pull the lesion out of the body; Push inward to make the outer hook 24 break away from the outer bayonet 23, disassemble the first sleeve 12 and the second sleeve 22, and then use a sharp object to push the inner hook 26 inward from the outside of the inner bayonet 25, so that The inner hook 26 breaks away from the inner bayonet 25, and the first inner push rod 11 and the second inner push rod 21 are disassembled; The retrieval bag is removed from the operating rod 1 and discarded together, and the operating rod 1 can be recycled after being sterilized, which can reduce medical costs compared with the currently used retrieval devices that are all disposable.
所述限位机构包括横向设置在所述第一内推杆11的外壁上的限位槽13、两个铰接设置在第一套筒12外壁上的限位手柄14、两个开设在第一套筒12 上的限位口15，限位手柄14的前端设置限位钩16，限位手柄14和第一套筒 12之间夹设弹簧片17，限位钩16通过限位口15进入第一套筒12内并钩住限位槽13；所述两个限位手柄14之间以及所述两个限位口15之间均以所述第一套筒12的中轴线为对称轴相互对称分布；所述限位槽13绕所述第一内推杆11外壁一周，限位槽13为10个，相邻限位槽13之间的间距相等。限位机构采用剪刀式设计，在第一套筒12两侧对称分布，避免偏斜，便于快速操作，限位钩16钩住限位槽13，避免第一内推杆11和第二内推杆21向前滑动。The limit mechanism includes a limit groove 13 horizontally arranged on the outer wall of the first inner push rod 11, two limit handles 14 hingedly arranged on the outer wall of the first sleeve 12, and two limit handles 14 set on the first sleeve 12. The limiting opening 15 on the sleeve 12, the front end of the limiting handle 14 is provided with a limiting hook 16, and a spring leaf 17 is sandwiched between the limiting handle 14 and the first sleeve 12, and the limiting hook 16 enters through the limiting opening 15. Inside the first sleeve 12 and hooked into the limiting groove 13; between the two limiting handles 14 and between the two limiting openings 15, the central axis of the first sleeve 12 is the axis of symmetry They are distributed symmetrically; the limiting grooves 13 circle around the outer wall of the first inner push rod 11, there are 10 limiting grooves 13, and the distances between adjacent limiting grooves 13 are equal. The limit mechanism adopts a scissors-type design, which is symmetrically distributed on both sides of the first sleeve 12 to avoid deflection and facilitate quick operation. The limit hook 16 hooks the limit groove 13 to avoid the first inner push rod 11 and the second inner push The rod 21 slides forward.
