Disposable foreskin cutting stapler

Abstract

The invention relates to the technical field of medical equipment, in particular to a disposable foreskin cutting stapler. The disposable foreskin cutting stapler comprises a concave seat, a staple chamber sleeve, a casing, a lead screw, a staple pushing piece, a movable handle and a connecting rod, wherein the lead screw is arranged in the casing, the staple chamber sleeve is arranged on the left side of the casing, the staple pushing piece and the concave seat are arranged in the staple chamber sleeve, the movable handle is installed on the casing, the connecting rod is connected with the casing and the movable handle, a safety clip is arranged on the casing, an adjusting nut is arranged at the tail end of the casing, an adjusting bolt is arranged at the end of the lead screw, exhaust through holes are formed in the concave seat, and a suture carrying hole is formed in the staple chamber sleeve. The disposable foreskin cutting stapler has the advantages that the operation time is effectively shortened during use, the stapler is convenient for a doctor to operate, the stapler is not only safe but also practical, the stress area is increased through the fish-tail-shaped adjusting nut, the stress points are increased, the appearance is attractive and the operating hand feeling is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a disposable circumcision stapler. Background technique [0002] There are the following disadvantages in the existing foreskin staplers on the market: 1. The concave seat has no vent hole. After the concave seat without vent hole is ligated, there will be air in the concave seat that cannot be removed, resulting in glans glans. It cannot fit perfectly with the concave seat, and the removed foreskin cannot meet expectations. 2. There is no wire hole in the staple cartridge sleeve. During the operation, the foreskin to be removed is ligated on the screw rod, and the position of cutting the foreskin cannot be adjusted during the operation. 3. There is no safe firing instruction. When the adjustment nut is slowly adjusted and tightened, the tissue is extruded, and the firing is performed for cutting and suturing, there is no instruction. It is controlled entirely by the o...

AI Technical Summary

Problems solved by technology

[0002] There are the following disadvantages in the existing foreskin staplers on the market: 1. The concave seat has no vent hole. After the concave seat without vent hole is ligated, there will be air in the concave seat that cannot be removed, resulting in glans glans. Unable to fully fit the concave seat, the removed foreskin cannot meet expectations

2. There is no wire hole in the staple cartridge sleeve. During the operation, the foreskin to be removed is ligated on the screw rod, and the position of cutting the foreskin cannot be adjusted during the operation.

3. There is no safe firing instruction. When the adjustment nut is slowly adjusted and tightened, the tissue is squeezed, and the firing, cutting and suturing are performed, there is no instruction. The control is all based on the operator's experience and feeling. The effect is poor and the expected purpose cannot be achieved.

4. There is no adjusting screw limit device. In existing products, when the adjusting nut is adjusted and tightened, the maximum tightening stroke of the screw rod cannot be effectively controlled, so the minimum matching gap between the concave seat and the casing cannot be guaranteed. Instruments risk pinching tissue when tightened

5. Cylindrical adjustment nuts. In the existing products, the adjustment nuts are basically cylindrical, with relatively small force contact surface and few force points, and it is laborious to adjust.

6. The existing foreskin staplers are equipped with relatively simple safety devices, which are inconvenient to remove

7. Most of the existing products are connected by ultrasonic welding, which has complicated procedures and is not conducive to the improvement of production efficiency.

8. During the operation of the existing product, when the concave seat is put into the staple magazine, the guide edge on the concave seat must be in a fixed position to be put into the guide groove of the pusher piece, and the alignment must be very accurate when entering the notch. Accurate, it is very inconvenient for the operator to use, and it is prone to alignment errors, resulting in instrument failure
