Background

Lung cancer is one of the common malignant tumors with poor prognosis in China. Most patients with early lung cancer or lung nodule can choose to receive lung section resection or sub-lung lobe resection operation to achieve the treatment purpose. At present, the linear cutting closer method or the electrotome ultrasonic knife method is mostly adopted in China clinically to cut and close tissues of an intersegmental plane. The linear cutting closer method can obviously reduce the incidence of complications such as postoperative incomplete face air leakage, blood seepage and the like, but has poor accuracy of the plane between cutting sections, has higher technical requirements for operating doctors, and can squeeze the irregular plane between the sections into a straight line, thereby seriously influencing the re-opening and ventilation functions of residual lung tissues near the incisal margin, reducing the postoperative tidal volume of patients and being not beneficial to improving the recovery of the postoperative lung functions and the life quality of the patients. Although the electrotome ultrasonic knife method is simple and convenient, and can accurately cut lung segment tissues according to an intersegmental plane, common complications such as air leakage, blood seepage and the like of a cut surface of the lung tissue can obviously increase the hospitalization time and medical cost of a patient, thereby limiting the clinical application of the electrotome ultrasonic knife method.

Detailed Description

As fig. 1 is the utility model discloses a structural schematic diagram, fig. 2 is the utility model discloses a support nail mechanism's structural schematic diagram, fig. 3 is the utility model discloses a structural schematic diagram of bottom plate, a negative pressure formula plane cutting closer, including main handle 1, firing bar handle 2, main connecting rod 3, firing bar 4, bottom plate 5, negative pressure adsorption device 6, support nail mechanism 7 and

metal peg

8, 3 one end of main connecting rod is fixed with main handle 1, and the 3 other ends of main connecting rod are fixed with

bottom plate

5, and 4 one ends of firing bar are fixed with

firing bar handle

2, and 4 other ends of firing bar are fixed with the nail mechanism 7 that supports of

extrusion metal peg

8, and 4 sliding fit of firing bar are connected in the inner chamber of main handle 1, and 5 internal fixations of bottom plate have negative pressure adsorption device 6. The negative pressure adsorption mechanism 6 is composed of a pipe body, adsorption holes 61 and a valve 62, the valve 62 is fixed on the bottom plate 5, the pipe body is fixed in the bottom plate 5, a plurality of adsorption holes 61 are distributed on the pipe body, and the pipe body is communicated with the valve 62. The nail pushing mechanism 7 is composed of a U-shaped plate 71 and a pressing plate 72, the U-shaped plate 71 is fixed at one end of the firing rod 4, more than one pressing plate 72 is fixed on the U-shaped plate 71, the pressing plate 72 penetrates through the bottom plate 5, and the pressing plates 72 are connected in sliding grooves in two sides of the bottom plate 5 in a sliding mode. And a plurality of positioning grooves for placing metal nails 8 are arranged on the bottom plate 5. And a limiting plate 9 for limiting the metal nails 8 is fixed on the bottom plate 5.

Referring to fig. 1, 2 and 3, the bottom plate 5 is provided with a rectangular groove, and all the metal nails 8 and the limiting plates 9 are placed in the rectangular groove. When the closer is to be used, the metal pins 8 are first placed one by one in positioning slots arranged in an array, which are distributed in a rectangular slot in the bottom plate 5. The metal nail in the positioning groove is positioned between the limiting plate 9 and the pressing plate 72. The user holds the main grip 1 and the trigger bar grip 2 by hand, so that the trigger bar grip 2 exerts force in the direction of the main grip 1, and the trigger bar grip 2 can drive the pressing plate 72 to support the metal nail 8 through the trigger bar 4 and the U-shaped plate 71, thereby clamping the metal nail 8 between the limiting plate 9 and the pressing plate 72.
