Problems solved by technology

However, in actual operation, it is found that the existing common linear cutting stapler cannot clearly display the stroke of the cutting knife and firing piece, so it is very inconvenient for the operation
[0004] This shows that the above-mentioned existing linear cutting stapler obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

Abstract

The invention relates to a linear cutting stitching instrument with a travel indicating device. The linear cutting stitching instrument comprises a fixed clamping plate, a closed clamping plate, a nail pressing seat assembly, a transmission mechanism, a conducting bar, a travel block, a transmission gear and an indicating wheel; one side of the closed clamping plate is provided with a chute; the transmission mechanism comprises a supporting connecting rod, a push knife connecting rod and a band knife rack; the front end of the supporting connecting rod is rotatably connected with the rear end of the push knife connecting rod through a pin shaft capable of sliding forwards and backwards along the chute; the transmission gear and the indicating wheel are rotatably arranged on the upper surface of the closed clamping plate, and the indicating wheel is engaged with the transmission gear; and row teeth engaged with the transmission gear is arranged on the upper surface of the travel block, the conducting bar is spliced with the travel block and arranged on one side of the closed clamping plate, the front lower end of the travel block is supported by a supporting plate spring arranged on the closed clamping plate, and the rear end of the conducting bar is connected with the supporting connecting rod and the push knife connecting rod through the pin shaft. The stitching instrument can be used for facilitating an operation, is suitable for open operation of enterectomy and gastrectomy, and is simple in structure, clear in indication, light and flexible.

Description

technical field [0001] The present invention relates to a medical device for surgical operations, in particular to a device with stroke indication [0002] The linear cutting stapler of the device. Background technique [0003] The linear cutting stapler is widely used in surgical operations for wound suturing, internal tissue suturing and cutting. The linear cutting stapler has two functions of suturing and cutting, and the excess tissue is removed while suturing the wound. This type of linear incision stapler generally includes upper and lower jaws, and a closing handle for closing the upper and lower jaws. The firing piece and the cutting knife in the magazine can move relative to the staple cartridge at the same time, and the push torque for driving the firing piece and the cutting knife to move. Staples are arranged in the staple cartridge, and the firing piece pushes the staple pusher in turn and pushes the staples to the staple abutment seat, and the cutter cuts off...
