Abstract

The invention provides a linear type stapler with an adjusting mechanism. The upper end and the lower end of an adjusting deflector rod are each provided with at least one step surface, at least three different step surfaces are arranged on the end surface, close to the adjusting deflector rod, of an adjusting slider, and at least three different step surfaces are arranged on the end surface, close to the adjusting deflector rod, of an adjusting base plate; when an adjusting toggle button is stirred, the adjusting deflector rod rotates along with the adjusting toggle button, the adjusting deflector rod is shifted relative to the adjusting slider at one end in the vertical directions of the step surfaces, and shifted relative to the adjusting base plate at the other end in the vertical directions of the step surfaces, and then a rivet holder assembly is driven to rotate relative to a nail cartridge base assembly until the thickness of the clamped tissue at the near end is consistent with that of the clamped tissue at the far end. Compared with an adjusting mechanism in the prior art, the adjusting mechanism has a wider adjusting range and more appropriate pressure and is more convenient to operate.

Description

technical field [0001] The present application relates to a linear stapler, especially a linear stapler with an adjustment mechanism. Background technique [0002] At present, the use of linear staplers has been quite common in clinical practice. The working principle of the linear stapler is to clamp the tissue by closing two handle assemblies (usually one handle includes the staple cartridge seat assembly, and the other handle includes the staple seat assembly), and then push out the staples in the staple cartridge Shaping, stitching the tissue together. Some linear staplers have a cutting function and are equipped with a cutting knife. After the tissue is stitched, the cutting knife cuts off the stitched tissue. [0003] The linear stapler with the above functions includes a first handle part and a second handle part, the first handle part includes a nail cartridge seat assembly, and the second handle part includes an abutment nail seat assembly; the nail cartridge seat...
