Problems solved by technology

[0004] 1. The existing anvil can move up and down and rotate the endoscopic cutting stapler, which cannot limit the firing handle during use, which affects the stability of the firing handle, reduces the squeezing effect, affects the quality of the operation, and wastes human resources;
[0005] 2. After the adjustment knob is turned, the adjustment knob cannot be fixed, and it is easy to be skewed due to mistouch, which reduces the quality of the operation and affects the suture effect;
[0006] 3. When the push block needs to be pulled, it is necessary to pull the push block with finger rests on both sides of the installation shell, which wastes human resources, affects the pulling quality, makes work inconvenient, and costs high

Embodiment 1

[0029] see Figure 1-6 , the present invention provides the following technical solutions: a laparoscopic cutting anastomat that anvil can move up and down and rotate, including holding handle 1, the upper end of holding handle 1 is provided with safety button 3, and the upper end of safety button 3 is provided with installation The housing 5 is provided with a nail cartridge assembly 7 on the side where the housing 5 is installed, and a firing handle 8 is provided on the side holding the handle 1. The position locking assembly 2 comprises a mounting frame 22, a connecting rod 23, a limit block 26, a blocking block 27, a guide groove 28 and a limit spring 29, wherein the surface side of the holding handle 1 is provided with a mounting frame 22, and the mounting frame 22 is installed The inside of the frame 22 is symmetrically provided with a guide groove 28, the inside of the guide groove 28 is provided with a blocking block 27, and a limit block 26 is arranged between the gui...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that: specifically, a clamping and fixing assembly 6 is provided between the installation housing 5 and the staple cartridge assembly 7, and the clamping and fixing assembly 6 includes a fixing rod 61 and a limit slide 62 , installation slider 63, damping rotating shaft 64, rotating rod 65, limit plug 66, adjustment knob 67, adjustment housing 68 and connecting frame 69, wherein, one side of installation housing 5 is provided with adjustment housing 68, adjusts The bottom end of the housing 68 is provided with a connecting frame 69, and the upper end of one side of the connecting frame 69 is provided with a fixed rod 61, and the inside of the fixed rod 61 is provided with a limit chute 62, and the inside of the limit chute 62 is provided with a mounting slider 63. The inside of the installation slider 63 is provided with a damping shaft 64, one side of the damping shaft 64 is provided with a rotating rod 65, the ...

Embodiment 3

[0044] This embodiment differs from Embodiment 1 and Embodiment 2 in that: Specifically, the surface of the installation housing 5 is provided with a convenient adjustment assembly 4, and the convenient adjustment assembly 4 includes a push block 42, a connecting block 43 and a finger groove 44, Wherein, push blocks 42 are arranged symmetrically on both sides of the installation housing 5 , connecting blocks 43 are arranged on the upper ends of the pushing blocks 42 , and finger slots 44 are evenly spaced inside the connecting blocks 43 .

[0045] By adopting the above-mentioned technical scheme, when the pushing block 42 needs to be pulled to move, the finger is inserted into the finger groove 44, and the connecting block 43 is pulled to drive the pushing block 42 to move along the installation housing 5, ensuring that the pushing block 42 is pulled Convenience and stability, improve work efficiency and save human resources.

[0046] Specifically, the inner surface of the fin...

Abstract

The invention discloses an endoscopic cutting anastomat with a nail anvil capable of moving up and down and rotating, and belongs to the technical field of anastomats. The endoscopic cutting anastomat comprises a holding handle, a safety button is arranged at the upper end of the holding handle, a mounting shell is arranged at the upper end of the safety button, a nail bin assembly is arranged on one side of the mounting shell, and the nail bin assembly is arranged on the other side of the mounting shell. A percussion handle is arranged on one side of the holding handle, a limiting and locking assembly is arranged on the surface of the holding handle corresponding to the percussion handle, the limiting and locking assembly comprises a mounting frame, a connecting rod, a limiting clamping block, a stop block, a guide groove and a limiting spring, the mounting frame is arranged on one side of the surface of the holding handle, and guide grooves are symmetrically formed in the mounting frame. By arranging the limiting and locking assembly, it is guaranteed that the percussion handle is locked stably, the squeezing effect is improved, the sewing quality is guaranteed, manpower resources are saved, the movement convenience of the percussion handle is improved, the use quality is guaranteed, and the working intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of staplers, in particular to a laparoscopic cutting stapler with an anvil that can move up and down and rotate. Background technique [0002] Laparoscopic stapler (endoscopic cutting stapler and disposable nail box) is one of the important instruments in laparoscopic surgery. It replaces traditional manual suture and uses titanium nails to separate or anastomose tissues. It is easy and fast to operate and greatly The operation time is shortened. The laparoscopic stapler makes the operation field narrow, and the manual anastomosis of deep parts is easy, accurate, firm and reliable, and the incidence of anastomotic leakage is significantly reduced. [0003] There are following problems in prior art: [0004] 1. The existing anvil can move up and down and rotate the endoscopic cutting stapler, which cannot limit the firing handle during use, which affects the stability of the firing handle, reduces the squee...
