Description

Technical Field

[0001] The utility model relates to the technical field of staplers, in particular to a stapler with a positioning function. Background Art

[0002] The stapler is a medical device used in surgical operations to replace traditional manual suturing. Its main working principle is to use titanium staples to separate or staple tissues, similar to a stapler. The stapler has the advantages of fast suturing, easy operation, tightness, appropriate tightness, strong tissue adaptability to staples, few side effects and surgical complications, and high surgical success rate. Therefore, it is widely used in various surgical fields in clinical practice, such as cardiothoracic surgery, gastrointestinal surgery, hepatobiliary spleen and pancreas surgery, general surgery, urology, etc.

[0003] At present, skin staplers are often needed to staple the skin in surgical operations. Their main purpose is to perform quick and accurate staples at skin incisions to promote wound healing. However, in actual use, traditional staplers do not have a positioning function. Doctors are often required to hold the skin on both sides of the wound with a handheld clamp and then place the stapler on the wound for suturing. Several alignment operations are required during the operation, which is cumbersome and cumbersome. Therefore, there is an urgent need for a stapler with a positioning function. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A stapler with a positioning function comprises a stapler body 1, a housing 3 is provided at the bottom of the front end of the stapler body 1, a trigger switch 4 is rotatably mounted at the middle of one end of the housing 3, a trigger rod 6 is rotatably mounted at one end of the trigger switch 4, a squeezing block 61 is provided at the front end of the trigger rod 6, and both sides of the squeezing block 61 are in squeezing contact with a clamping plate 8;

[0024] Furthermore, a rotating rod 81 is provided at the bottom of each clamping plate 8, a lower connecting rod 82 is provided at the bottom of the rotating rod 81, and a positioning clamping plate 5 is provided at the bottom of the lower connecting rod 82, wherein the two ends of the rotating rod 81 are respectively rotated in the rotating seat 9, and a return torsion spring 10 is provided at the rotating end of the rotating seat 9.

[0025] The front end of the stapler body 1 is provided with a suturing mechanism 2, and the middle part is provided with a trigger mechanism 21.

[0026] Moreover, the upper part of the trigger switch 4 is rotatably installed inside the shell 3 through a rotating shaft 41, and a spring 7 is provided on one side of the trigger switch 4, the spring 7 is connected to the inner wall of the shell 3, and a bearing 42 is provided on the other side of the trigger switch 4, and a trigger rod 6 is rotatably installed on the bearing 42 for upper limit.

[0027] In addition, a pair of rotating seats 9 are arranged inside the front end of the shell 3, and a rotating rod 81 is rotatably mounted on each rotating seat 9. A clamping plate 8 is arranged on the upper part of the rotating rod 81, and a positioning clamping plate 5 is arranged on the lower part through a lower connecting rod 82.

[0028] At the same time, each clamping plate 8 extends and tilts inward, and a squeeze block 61 is clamped between the clamping plates 8. The squeeze block 61 is narrow at the top and wide at the bottom, so that the squeeze block 61 can open the clamping plates 8, thereby enabling the positioning clamping plate 5 to achieve a clamping operation.

[0029] Furthermore, the positioning clamping plate 5 extends out of the bottom of the housing 3, and the positioning clamping plate 5 is in an arc shape that is concave inward, and the inner wall of the positioning clamping plate 5 is provided with concave and convex patterns. By providing patterns in the positioning clamping plate 5, it is ensured that it has a high friction coefficient with the skin, so that the skin can be clamped and gathered.

[0030] In the present embodiment, the operator holds the stapler body 1 with one hand, hooks the trigger switch 4 with the index finger, and holds the trigger mechanism 21 with the other fingers, and at the same time presses the suturing mechanism 2 against the skin to be sutured, and then presses the trigger switch 4 with the index finger, and the trigger switch 4 rotates through the rotating shaft 41, so that the trigger rod 6 moves forward, and the trigger rod 6 drives the extrusion block 61 to move forward and extend into the clamping gap between the splints 8 on both sides thereof. Since the extrusion block 61 has a structure that is narrow at the top and wide at the bottom, the splints 8 on both sides are stretched outward and rotated by the rotating rod 81. The rotation of the rotating rod 81 drives the positioning clamping plate 5 at the bottom to the opposite direction, that is, to shrink inward, and then the positioning clamping plate 5 will clamp and gather the skin. At this time, the trigger mechanism 21 is pressed by the other fingers to make the suturing mechanism 2 work and suture the wound.

[0031] In actual use, the two sides of the rotating rod 81 rotate in the rotating seat 9 through the reset torsion spring 10. The reset torsion spring 10 ensures that the rotating rod 81 can generate a return torque each time it rotates, thereby resetting the clamping plate 8.

[0032] In the utility model, by holding the stapler body 1 and hooking the trigger switch 4 with the index finger, in the actual operation process, by aligning the suturing mechanism 2 with the wound, while pressing against the skin, by pressing the trigger switch 4, the arc-shaped positioning clamping plate 5 at the bottom is driven to rotate inward, and the patient's skin is clamped and contracted, while keeping the index finger still, the trigger switch 4 is pressed by the remaining fingers, so that the suturing mechanism 2 sutures the gathered skin. Compared with the traditional operation method, this device can be positioned quickly without the need for coordinated operation with the help of multiple tools, avoiding cumbersome alignment and positioning steps, and then the skin can be gathered and sutured, effectively improving work efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
