Linear suturing and cutting device

Abstract

The invention discloses a linear suturing and cutting device, which comprises an upper tong clamp, a lower tong clamp, a closed handle, a nail anvil and a nail cabin, wherein a nail pushing rod and a cutter pushing rod which can simultaneously move along the axial line of an appliance are arranged in the nail cabin, one end of the nail pushing rod and one end of the cutter pushing rod are respectively matched and arranged on a slide block, a push button base is arranged on the slide block and is relatively fixed with the slide block, at least one push button is arranged on the push button base in a pivoted way, and the push button can be switched between two kinds of states including one state with the operation surface vertical to the axial line of the appliance and one state with the operation surface parallel to the axial line of the appliance. The linear suturing and cutting device has the main beneficial effects that the push button is opened and extends out of the tong clamps, the special operation requirements can be met, the push button is tightly pasted with the tong clamp after being folded, the integral size of the appliance can be relatively reduced, the package and transportation cost is relatively reduced, after the operation is completed, the push button retreats and is folded, the operation completion indicating effect is realized, the structure of the push button is simple, the assembly is convenient, and the linear suturing and cutting device is suitable for practical use.

Description

technical field [0001] The invention relates to a medical stapling device, in particular to a linear sewing cutter for surgical operations, belonging to the technical field of medical instruments. Background technique [0002] Surgical linear suture cutters are widely used for wound suturing, internal tissue suturing and cutting. A typical linear sewing cutter, as disclosed in US Pat. No. 5,129,570, has two functions of suturing and cutting at the same time, that is, excess tissue is excised while suturing the wound. This type of linear seam cutter generally includes two upper and lower jaws, an anvil and a staple bin that are relatively arranged at the far ends of the upper and lower jaws, and a closing handle for closing the upper and lower jaws; There is a pusher rod that can move simultaneously along the axis of the instrument and a pusher rod with a cutter at the far end. Both the pusher rod and one end of the pusher rod are arranged on a slider; A number of nail hole...

Problems solved by technology

The disadvantage of the push button of this structure is that the doctor can only push the push button on one side of the upper and lower jaws. Once the instrument is placed in a special operating position, the doctor cannot control the push button well. It will greatly reduce the operating comfort of the linear seam cutter

Also, the disadvantage of the push button of this structure is that the push button cannot be opened simultaneously on both sides of the jaw, resulting in the defects mentioned above
