Embodiment 1

[0042] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of a series of precision type blood vessel linear cutting stapler and nail box under the laparoscope of the present invention. A series of precise linear blood vessel cutting stapler and nail box under endoscope, said stapler and nail box include nail box body 1, nail drill 2, rotary joint 3, first connecting tube 4, second connecting tube 5 , rotary head 6, rotary knob 61, firing trigger 7, handle 8, reset cap 9; described nail magazine body 1 and nail drill 2 are connected with one end of rotary joint 3 by hinge shaft respectively; described rotary joint 3 The other end of the first connecting pipe 4 is connected with the first connecting pipe 4 through a rotating shaft; the other end of the first connecting pipe 4 is connected with the second connecting pipe 5 through a detachable joint; the rotating head 6 is arranged on the second connecting pipe 5 One side of the rotary head 6 is prov...

Embodiment 2

[0050] This embodiment is basically the same as Embodiment 2, the difference is that the beak-shaped guide body 22 is detachably connected to the nail drill body 21, and the beak-shaped guide body 22 of different specifications can be replaced according to the needs of the operation. Because the physiological structures of different human bodies are different, the beak-shaped guide body 22 of the corresponding specification can be replaced according to the needs, which is highly targeted, helps to improve the success rate of the operation, and reduces the consumption of consumables at the same time.

[0051] The present invention provides a precise series of blood vessel linear cutting stapler and nail box under the endoscope, which is easy to operate, flexible to use, easy to pass through the blood vessel to be closed, and realizes the precise treatment of blood vessels during lung surgery, especially lung lobe and lung segment surgery. , especially the treatment of blood vess...

Abstract

The invention relates to endoscopic precision-type series vascular linear stapling instrument and loading unit. The stapling instrument and loading unit comprise a loading unit main body, a nail drill, a rotating joint, a first connecting tube, a second connecting tube, a rotating head, a rotating knob, a trigger, a handle and a resetting cap, wherein both the first connecting tube and the second connecting tube are 4.5-5.5mm in diameter; the loading unit main body is 4.5-5.5mm in diameter; the loading unit main body is 2.5-3.5mm long; the nail drill comprises a nail drill main body and a guide body; and the guide body is represented as a bill. The linear stapling instrument and loading unit provided by the invention have the advantages that the linear stapling instrument and loading unit are convenient to operate and flexible to use and are capable of penetrating blood vessels to be closed; precise vascular treatment in a pulmonary surgery, in particular pulmonary lobe and pulmonary segment surgeries, can be implemented, and especially, vascular treatment on some complex anatomical sites can be obviously simplified, so that the safety of the surgeries can be improved and consumables can be reduced; and the linear stapling instrument and loading unit have a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endoscopic precision series blood vessel linear cutting stapler and a nail box. Background technique [0002] At present, the incidence of lung cancer in China is rapidly rising. Early lung cancer is treated with minimally invasive surgery under thoracoscopic surgery. Minimally invasive surgical instruments play a huge role in surgery. Various lung operations include lobectomy and segmentectomy. All of them need to be completed with minimally invasive surgical instruments, especially the number of lung segment operations is rapidly increasing in early lung cancer operations. [0003] When performing lung segment surgery, the surgeon needs precise treatment of blood vessels and continuous closure of blood vessels. The usual method is to use a laparoscopic cutter and stapler. The laparoscopic cutting stapler mainly includes a nail drill, a nail magazine, and a firing tr...
