Description
Technical field
The present invention relates to a kind of medical stapling instrument, the linear type stitching cutting device that especially a kind of surgical operation is used, 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 U.S. Pat 5129570 discloses, has simultaneously and sews up and two functions of cutting, in 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 the closed handle of the upper and lower clamp of closure; In this nail bin, be provided with the push broach bar that the ejector pin bar that can simultaneously move along apparatus axis and far-end are provided with cutting knife, one end of described ejector pin bar and push broach bar is all disposed on a slide block; Described nail bin surface is arranged and is provided with several nail holes along apparatus axis, and each nail is provided with pushing slice of nail and suturing nail in hole; Described slide block moves and drives described ejector pin bar to promote successively pushing slice of nail and push described suturing nail to nail anvil to form in and treat on suture tissue, and drives described cutting knife that the tissue between described nail bin and nail anvil is cut off or otch.
Apparatus is in the market for driving push button that described slide block moves to be generally all arranged on the left and right sides of upper and lower clamp, so that doctor's operation, as U.S. Pat 5129570 discloses a kind of push button moving for promoting slide block, ejector pin bar, cutting knife, 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 a side of upper and lower clamp, once when apparatus is placed in a special operating position, while causing doctor that this push button can not be controlled well, can reduce widely the operation comfort of this Linear stapling cutter.And on the other hand, right-hand man's custom of doctor also can cause the use inconvenience of this apparatus.
In order to solve above-mentioned technical problem, U.S. Pat 7419081, US7568604 have disclosed a kind of pushing button structure of novel " W " type, and this push button and slide block are pivotally connected, and two operating portions of this push button are selectively stretched out in outside the clamp of apparatus.In the time that doctor need to promote push button from left side, the push button operating portion in clamp left side is stretched out in outside clamp, now the push button operating portion on clamp right side draws in and is closely attached on clamp.In general, clamp also can be installed with a plastics clamp shell for the protection of clamp outward, and the push button operating portion drawing 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, can make the outer deformation of apparatus entirety large, packing and cost of transportation increase.And prior art also has a topmost problem: in the time that doctor promotes to stretch out in the left side push button operating portion outside clamp, drawing in and be closely attached on the push button operating portion on the right side of clamp also can be along with slide block moves together, because doctor's operating habit is to live clamp shell with hand rest, at this moment the push button operating portion on right side can pass the gap between doctor's the palm of the hand and clamp shell, the push button operating portion on right side probably can clip to doctor's medical gloves between push button operating portion and clamp in mobile process, thereby cause all can not moving before and after push button, cause malpractice.
Summary of the invention
