Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a laparoscopic surgical intelligent cutting stapler with a replaceable stapler magazine. Background Art

[0002] The laparoscopic stapler is one of the important instruments in laparoscopic surgery. It replaces traditional manual suturing and uses titanium nails to separate or anastomose tissues. It is easy and quick to operate, greatly shortening the operation time. The laparoscopic stapler makes it easy to perform anastomosis that is difficult to perform manually in a narrow surgical field or deep area. It is accurate, firm and reliable, and can significantly reduce the incidence of anastomotic fistula. According to the different power transmission methods, the stapler can be divided into manual and electric. Compared with the manual stapler, the electric laparoscopic stapler has better hemostatic effect, so it has improved both clinical value and economic value.

[0003] Among them, patent CN113367751A discloses a laparoscopic surgical cutting stapler with a replaceable stapler, which includes a stapler body, a connecting tube is provided at the distal end of the stapler body, a stapler seat is provided on the surface of the connecting tube, a stapler seat is plugged into the distal end of the connecting tube, and the proximal end of the stapler seat penetrates the connecting tube and extends to the interior of the connecting tube. For this cutting stapler, medical staff only need to drive the first U-shaped plate to move to the left through the first connecting plate to firmly fix the fixing block in the first limiting groove, which can greatly reduce the difficulty of medical staff to install the stapler seat and make it easier for medical staff to get started.

[0004] However, in the prior art, the cutting stapler has the following defects during use:

[0005] 1. When clamping tissue, the thickness of tissue in each person and each part is different. Therefore, when clamping and cutting tissue, the clamping force on the tissue will be different. When the force is too large, it is easy to damage the tissue, which will be detrimental to the recovery of the tissue after cutting.

[0006] 2. When the tissue needs to be cut, the push rod and the push knife are usually driven by manually pressing the handle to cut the tissue. Therefore, the tissue cannot be cut quickly during the cutting process, which will cause excessive blood to flow out of the tissue.

[0007] 3. Most cutting staplers can only replace the stapler cartridge. Therefore, when the stapler execution head is damaged, the damaged part cannot be replaced and only the entire stapler can be replaced, which will make the replacement cost high and cause waste.

At the same time, it can also realize the cutting of the tissue at a uniform and stable speed under the action of the motor 906, which can avoid damage to the tissue during the cutting process, thereby improving the stability of the cutting stapler; through the arrangement of the extension tube 5 and the stapler seat 8, the installation of the stapler seat 8 is realized, which allows the staff to conveniently replace the stapler seat 8, reduces the difficulty of replacing the stapler seat 8 for the staff, thereby improving the replacement efficiency of the stapler seat 8 for the staff, and at the same time, under the action of the spring 505, an upward thrust can be generated on the stapler seat 8, so that the cutting stapler plays a buffering role in the process of clamping the tissue, thereby avoiding excessive clamping force causing Tissue damage can be reduced, so that the tissue can recover better after the cutting is completed; through the setting of the connecting mechanism 6, the connection between the connecting tube 4 and the extension tube 5 is realized, and the extension tube 5 can be conveniently installed and disassembled, which improves the work efficiency of the staff in installation and disassembly. At the same time, when the cutting stapler is not needed, the cutting stapler can be conveniently stored by disassembling part of the extension tube 5, and when the extension tube 5 part is damaged, the extension tube 5 part can be replaced, thereby reducing the maintenance cost of the cutting stapler and avoiding waste; by setting the pushing mechanism 9, the pushing rod 910 is pushed, and the pushing rod 910 can be driven by the motor 906 to move back and forth, so that the pushing knife can be driven by the pushing rod 910 to cut the tissue without manual pushing, and the tissue can be cut evenly and smoothly without causing more blood to flow out of the tissue.
