FIG. 5 is a schematic view of the connection structure of the second trigger driving the middle binding clip to move.

Detailed Description

Referring to fig. 1-5, the reverse laparoscope clip applier of the present invention comprises a rod body 1, a handle 2 is disposed at the rear end of the rod body 1, an upper binding clip 3 and a lower binding clip 4 are hinged to the front end of the rod body 1, bayonets are respectively disposed at the free ends of the upper binding clip 3 and the lower binding clip 4, a first trigger 5 is connected to the rear end of the rod body 1, and the first trigger 5 is used for driving the upper binding clip 3 and the lower binding clip 4 to close or open (in the prior art, the detailed structure and working principle are not described any more); the front end of the rod body 1 is connected with a middle tong head 6 in a sliding mode, the free end of the middle tong head 6 is also provided with a bayonet, and the rear end of the rod body 1 is connected with a second trigger 7 which drives the middle tong head 6 to move back and forth in a telescopic mode.

Furthermore, a sliding rod 8 is fixed at the rear end of the middle tong head 6, the sliding rod 8 is connected in an axial cavity of the rod body 1 in a sliding mode along the axial direction, a return spring 9 is connected between the rear end of the sliding rod 8 and the rear wall of the axial cavity, a guide groove 101 is formed in the bottom of the axial cavity along the axial direction of the axial cavity, the second trigger 7 is connected in the guide groove 101 in a sliding mode, and the upper end of the guide groove 101 is fixedly connected with the sliding rod 8. The slide bar 8 can be driven to move backwards by pressing the second trigger 7 backwards, so that the middle tong head 6 is driven to retract towards the inner direction of the rod body 1, and after the second trigger 7 is loosened, the slide bar 8 drives the middle tong head 6 to reset under the action of the reset spring 9.

The utility model discloses an application steps:

1) As shown in fig. 1, the jaw of the clip applier is sleeved into a blood vessel 10 to be clipped, the open end of the hemostatic clip 11 faces the end of the rod body 1, the middle part of the hemostatic clip 11 is clipped at the bayonet of the upper binding clip 3, and the lower end of the hemostatic clip 11 is clipped at the bayonet of the middle binding clip 6;

2) As shown in fig. 2, the second trigger 7 is operated to retract the middle jaw 6, so that the semi-closed hemostatic clamp 11 is ejected, and the hemostatic clamp 11 is clamped at the bayonet of the lower jaw 4;
