Description
Technical field
The present invention relates to a kind of medical stapling instrument, especially a kind of linear type stitching cutting device of surgical operation, belongs to technical field of medical instruments.
Background technology
Medical linear sprig closes cutting device and is widely used in wound suture, interior tissue stitching and cutting.Typical linear type stitching cutting device as US Patent No. 5129570 disclose, have simultaneously sew up with cutting two functions, namely while carrying out wound suture by unnecessary cutting tissue.Such apparatus generally comprises upper and lower two clamps, is oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Be provided with the push broach bar that can be provided with cutting knife along the ejector pin bar of apparatus axis movement simultaneously and far-end in this nail bin, one end of described ejector pin bar and push broach bar is all disposed on a slide block; Described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with pushing slice of nail and suturing nail in each nail; Described slide block moves and drives described ejector pin bar to promote pushing slice of nail successively and push described suturing nail to nail anvil to form in tissue to be stapled, and drives described cutting knife to be cut off or otch by the tissue between described nail bin and nail anvil.
The left and right sides of apparatus in the market for driving the push button of described slide block movement to be generally all arranged on upper and lower clamp, so that doctor's operation, as US Patent No. 5129570 discloses a kind of push button for promoting slide block, ejector pin bar, cutting knife movement, described push button is relative with slide block fixing, and stretches out in left side or the right side of described upper and lower clamp.The deficiency of the push button of this structure is: doctor can only promote push button in the side of upper and lower clamp, once when apparatus is placed in a special operating position, when causing doctor can not control this push button well, then can reduce the operation comfort of this Linear stapling cutter widely.And on the other hand, the handedness of doctor also can cause the use inconvenience of this apparatus.
In order to solve above-mentioned technical problem, US Patent No. 7419081, US7568604 disclose a kind of pushing button structure of novel " W " type, this push button and slide block pivotally connected, two of this push button operating portions are selectively stretched out in outside the clamp of apparatus.When doctor needs to promote push button from left side, then stretch out in outside clamp by the push button operating portion on the left of clamp, the push button operating portion now on the right side of clamp then draws in and is closely attached on clamp.In general, clamp also can be installed with one outward for the protection of the plastics clamp shell of clamp, then the push button operating portion drawn in can be adjacent to clamp shell.The deficiency of the push button of this structure is, the operating portion of push button both sides can not side by side draw in, and the outer deformation of apparatus entirety can be made large, and packaging and cost of transportation increase.And prior art also has a topmost problem: when doctor promotes the left side push button operating portion stretched out in outside clamp, to draw in and the push button operating portion being closely attached on the right side of clamp also can move along with slide block together, because the operating habit of doctor is for live clamp shell with hand rest, at this moment the push button operating portion on right side can pass from the gap between the palm of the hand of doctor and clamp shell, the medical gloves of doctor probably can clip between push button operating portion and clamp by the push button operating portion on right side in the process of movement, thus cause all can not moving before and after push button, cause malpractice.
Summary of the invention
