Disposable titanium clamp synchronization opposite-direction operation device

Abstract

The invention discloses a disposable titanium clamp synchronization opposite-direction operation device which is provided with a stirring block, a reset spring, a first opposite-direction connecting piece, a second opposite-direction connecting piece, a double-gear plate wheel and a sleeve rod. A first opposite-direction seat and a first rack are arranged on the first opposite-direction connecting piece. A second opposite-direction seat, a stirring seat, a second rack and a sleeve rod clamping groove are arranged on the second opposite-direction connecting piece. The second opposite-direction seat is provided with a first opposite-direction seat supporting plate. A first gear, a second gear, a mandrel are arranged on the double-gear plate wheel. The first opposite-direction seat is arranged on the first opposite-direction seat supporting plate in a sleeved mode. The first opposite-direction seat is matched with the first opposite-direction seat supporting plate in a sliding mode. The mandrel and a double-gear plate wheel clamping groove are connected in a rotating mode. The first gear and second rack are meshed. The second gear and the first rack are meshed. The sleeve rod is clamped in the sleeve rod clamping groove. The two ends of the reset spring are respectively connected with the sleeve rod and a spring seat. The stirring seat is pressed on the stirring block. The first gear and the second gear are relatively arranged. The disposable titanium clamp synchronization opposite-direction operation device is reasonable and simple in structure, operation is convenient, and synchronization opposite-direction operation is achieved.

Description

technical field [0001] The invention relates to a synchronous and non-directional operating device for disposable titanium clamps used in minimally invasive laparoscopic surgery. Background technique [0002] In human laparoscopic surgery, it is necessary to use titanium clips and titanium clips to clamp blood vessels and small organs in the human body. Most of the existing technologies are single-shot titanium clips that are reused. Although the reusable single-shot titanium clamp can effectively clip blood vessels and small organs, it is not disposable and can be reused after disinfection. Transfer between the nurse and the operator. After applying a titanium clip, the operator needs to pass the single-shot titanium clip to the nurse to complete the installation of the next titanium clip, and then pass it to the operator. This not only prolongs the operation time, but also greatly It is easy to cause cross-infection; at present, there are reusable semi-automatic continuou...

Problems solved by technology

Although the reusable single-shot titanium clamp can effectively clip blood vessels and small organs, it is not disposable and can be reused after disinfection. Transfer between the nurse and the operator. After applying a titanium clip, the operator needs to pass the single-shot titanium clip to the nurse to complete the installation of the next titanium clip, and then pass it to the operator. This not only prolongs the operation time, but also greatly It is easy to cause cross-infection; at present, there are reusable semi-automatic continuous titanium clamps in China, wherein the publication numbers are respectively: two patent publications of CN101049251A and CN201001755Y disclose a titanium clamp device, which is mainly composed of clamps and It is composed of a titanium clip box. When using it, it is necessary to insert the titanium clip into the titanium clip box and install the titanium clip manually. However, in actual operations, the surgeon generally operates with one hand, that is, the surgeon is operating different instruments with both hands. Surgery, it is difficult for the operator to free the other hand to fill the titanium clip operation; so the operation is inconvenient, the operation is troublesome, and the titanium clip is reused, which is easy to cause cross infection
