Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0012] As shown in the accompanying drawings, the reference signs and components involved in the accompanying drawings are as follows:

[0013] 1. Handle 2. Pliers

[0014] 3. Connecting shaft

[0015] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of a vascular cancer thrombectomy forceps according to the present invention. The vascular cancer thrombus extraction forceps includes a handle 1 and a forceps body 2. The handle 1 and the forceps body 2 are connected by a connecting shaft 3 and can form a Pivoting, the pliers body 2 becomes a semi-ellipsoid.

[0016] It should be noted that the handle 1 and the pliers body 2 are respectively provided with two, the two handles 1 and the pliers body 2 are connected by a connecting shaft 3 and can form a pivot, and the pliers body 2 is semi-ellipsoidal, When the tw...

Abstract

The invention discloses tongs used for taking vessel cancer embolus. The tongs used for taking the vessel cancer embolus comprise a handle and a tong body. The handle is connected with the tong body in a pivot-rotating mode through a connection shaft. The tong body is in a semi-oval spherical shape. Compared with the prior art, the tongs used for taking the vessel cancer embolus have the advantages of being simple in structure, convenient to use, good in vessel cancer embolus taking effect due to the fact that the vessel cancer embolus can not be damaged when clamped, capable of reducing surgical risk, easy to clean during a surgery, and capable of reducing the implantation metastasis probability of iatrogenic tumor.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a thrombectomy device, in particular to a thrombus-retrieving forceps for vascular cancer thrombi. Background technique [0002] When cholangiocarcinoma and liver cancer develop to the middle and late stages, tumor thrombi often invade blood vessels and bile ducts, and patients with vascular tumor thrombi are often encountered during surgery. At present, there is no special thrombectomy forceps for vascular cancer thrombus clinically, and the thrombectomy instruments used are all replaced by existing instruments such as biliary tract lithotripsy forceps or tweezers. This method is easy to crush the tumor thrombus, and the tumor thrombus cannot be removed completely at one time, and there may be residual tumor thrombus Contents of the invention [0003] In order to overcome the deficiencies of the prior art above, the purpose of the present invention is to provide a throm...
