Linear suturing and cutting instrument

Abstract

The invention discloses a linear suturing and cutting instrument, which comprises an upper forceps holder, a lower forceps holder, ejector pin rods capable of moving simultaneously, a push-type cutter arbor with a cutter at a far end, a locking piece and a slide block which are pluggable mutually, and two push buttons symmetrically and pivotally arranged on two sides of the locking piece. When the slide block is plugged with the locking piece, the two push buttons are drawn in two sides of the lower forceps holder; and when the slide block is separated from the locking piece, only one push button is opened and is relatively fixed on the slide block, and the other push button is drawn in and is relatively fixed on the locking piece. The linear suturing and cutting instrument has the beneficial effects that the two push buttons are simultaneously drawn in and clung to the forceps holders, so that the size of the whole instrument can be relatively reduced, and the packaging and transportation cost can also be relatively reduced; when one of the two push buttons pushes the slide block to move, the other push button is fixed on the locking piece, so that the occurrence of the phenomenon that the push button at a non-working state is moved to clamp a medical glove of a doctor is avoided; and the linear suturing and cutting instrument has a simple structure, is convenient to assemble, and is very practical.

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...

AI Technical Summary

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

The disadvantage of the push button with this structure is that the operating parts on both sides of the push button cannot be folded at the same time, which will increase the overall space of the device and increase the cost of packaging and transportation.

And the prior art also has a major problem: when the doctor pushes the left side push button operating part stretching out of the clamp, the push button operating part on the right side that is close to the clamp will also follow. The sliders move together. Since the doctor’s operating habit is to hold the clamp shell with his hands, the push button operation part on the right will pass through the gap between the doctor’s palm and the clamp shell, and the push button on the right will operate In the process of moving, the doctor's medical gloves are likely to be caught between the push button operation part and the jaw, so that the push button cannot move forward and backward, resulting in medical accidents
