Two-section rod for removing object from abdominal cavity

Abstract

The invention discloses a two-section rod for removing an object from the abdominal cavity. The rod comprises an operation rod and a connecting rod at the front end of the operation rod; the operation rod comprises a first inner pushing rod and a first sleeve at the exterior of the first inner pushing rod, and the first sleeve prevents the first inner pushing rod from detaching forwards through a limit mechanism; the connecting rod comprises a second inner pushing rod and a second sleeve at the exterior of the second inner pushing rod; two outer clamping openings are formed in the first sleeve, two outer clamping hooks are fixedly connected to the rear end of the second sleeve, and the outer clamping hooks are matched with the outer clamping openings; the front end of the first inner pushing rod is of a hollow structure and provided with two inner clamping openings, two inner clamping hooks are fixedly connected to the rear end of the second inner pushing rod, and the inner clamping hooks are matched with the inner clamping openings. According to the two-section rod for removing the object from the abdominal cavity, the operation rod is connected with an object-removing bag through the connecting rod, does not need to be abandoned along with the connecting rod and the object-removing bag after an operation and can be recycled for usage, and the medical cost is saved; the first inner pushing rod and the second inner pushing rod can be prevented from accidentally sliding forwards during the operation through the limit mechanism, and therefore the abdominal organs are prevented from accidental injuries during the operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a two-stage abdominal object extraction rod. Background technique [0002] 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. [0003] 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...

Problems solved by technology

[0003] 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 for one time, and the retrieval bag together with the operating rod is discarded as a whole, the operation cost is high, and it brings a greater economic burden to the patient

[0004] In addition, the friction ring is relatively fixed between the sleeve of the fetching device and the inner push rod, but it cannot completely prevent the inner push rod from sliding forward
