Embodiment 1

[0026] like Figure 1 to Figure 4 As shown, a vibrating liver forceps includes a pair of hinged forceps body 1, five vibration modules 2 and four absorption grooves 3 are arranged on the clamping surface of the forceps body 1, and the vibration modules 2 and the absorption grooves 3 are spaced apart distributed. The vibration module 2 includes a vibration module box body 4, a vibration device and a vibration body 20, the vibration device is connected with the vibration body 20, the vibration device is connected with an external controller, and the absorption tank 3 is communicated with a negative pressure air source. In the embodiment, the negative pressure air source is the vacuum port of the ward. The forceps body 1 includes a clamping section and an operating section, the hinge of the forceps body 1 is located between the clamping section and the operating section, the cross section of the clamping section is U-shaped, and the U-shaped cavity of the clamping section forms ...

Embodiment 2

[0029] like Figure 5 to Figure 8 As shown, the vibration module box body 4 is a cuboid with a top cover. There are four vibration modules 2 and five absorption grooves 3 . Each vibrating body 20 includes a top plate and a sliding column, the top plate and the sliding column are integrally formed, the top plate is located outside the top cover of the vibration module box body 4, and the sliding column is slidably inserted in the center hole of the vibration module box body 4 top cover and is connected to the vibration module box body 4. The walls of the central bore remain in sealing contact. Described vibrating device comprises gas control gear 11 and extension spring 7, and vibrating body 20 bottom surface is connected with vibrating module box body 4 by extension spring 7, and the top plate of vibrating body 20 exceeds vibrating module box body 4 sides, and is connected with caliper body 1. The central axis is vertical to form a protruding lip 8. A rack 9 is fixed on the ...

Embodiment 3

[0032] There are six vibration modules 2, and seven absorption grooves 3. All the other are with embodiment 1.

Abstract

The invention discloses a pair of vibrating liver forceps. The pair of vibrating liver forceps comprises a pair of hinged forceps bodies. A plurality of vibrating modules and absorption grooves are formed in a clamping face of each forceps body, the vibrating modules and the absorption grooves are distributed in a spaced manner, a vibrating device is arranged below the vibrating modules and is connected to a controller, and the absorption grooves communicate to a negative gas source. The vibrating liver forceps can be used for clamping liver in a large area to crush, so that the vibrating liver forceps have large simultaneous action areas, the working efficiency is improved greatly, the hepatectomy process is accelerated, the working strength of medical staff is reduced, and paint of the patient is alleviated.

Description

technical field [0001] The present invention relates to a medical device, more particularly, it relates to a vibrating liver forceps for performing liver resection. Background technique [0002] Hepatectomy is often performed in the treatment of malignant liver disease. At present, CUSA (ultrasonic suction device) has been widely used in the implementation of liver resection. CUSA consists of three parts: vibration cutting, perfusion and suction. The hollow titanium tube vibrates longitudinally. When it contacts the liver tissue, the parenchyma is crushed, the liver tissue is separated, and the cell fragments are washed by the perfused saline and then sucked away by the hollow titanium tube. At the same time, relatively tough tissues such as blood vessels and bile ducts are not easy to be crushed and preserved, that is, the tissues are pulverized and emulsified by ultrasonic vibration, and then sucked by negative pressure to achieve the removal of diseased tissues. Howeve...
