Description
Technical field
This utility model relates to a kind of medical stapling instrument, and the linear type stitching cutting device that especially a kind of surgical operation is used belongs to technical field of medical instruments.
Background technology
The medical linear sprig closes cutting device and is widely used in wound suture, interior tissue stitching and cutting.Typical linear type stitching cutting device such as US Patent No. 5129570 announcements, have simultaneously and sew up and cut two functions, namely when carrying out wound suture with 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 the closed handle that is used for closed upper and lower clamp; Being provided with in this nail bin can be along apparatus axis mobile ejector pin bar and the far-end push broach bar that is provided with cutting knife simultaneously, and an end of described ejector pin bar and push broach bar all is equipped on the slide block; Described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and suturing nail in each nail hole; Described slide block moves and drives described ejector pin bar and promote successively pushing slice of nail and push described suturing nail to nail anvil to form in and treat on the suture tissue, and drives described cutting knife the tissue between described nail bin and nail anvil is cut off or otch.
Apparatus in the market is used for driving the left and right sides that push button that described slide block moves generally all is arranged on upper and lower clamp, so that doctor's operation, a kind of push button for promoting slide block, ejector pin bar, cutting knife and moving is disclosed such as US Patent No. 5129570, 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: the doctor can only promote push button in a side of upper and lower clamp, in case when apparatus places a special operating position, when causing the doctor that this push button can not be controlled well, then can reduce widely the operation comfort of this Linear stapling cutter.And on the other hand, doctor's right-hand man custom also can cause the use inconvenience of this apparatus.
In order to solve above-mentioned technical problem, US Patent No. 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.When the doctor need to promote push button from the left side, then the push button operating portion with clamp left side stretched out in outside the clamp, and the push button operating portion on clamp right side then drew in and was closely attached on clamp this moment.In general, clamp also can be installed with a plastics clamp shell for the protection of clamp outward, and the push button operating portion that then draws in can be adjacent to the 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 integral body large, packing and cost of transportation increase.And prior art also has a topmost problem: during left side push button operating portion outside surgeon pushed on stretches out in 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 is mobile together, because doctor's operating habit is for to live the clamp shell with hand rest, at this moment the push button operating portion on right side can pass from doctor's the palm of the hand and the slit between the clamp shell, the push button operating portion on right side probably can clip to doctor's medical gloves between push button operating portion and the clamp in mobile process, thereby cause all can not moving before and after the push button, cause malpractice.
