[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1 to 4 As shown, an embodiment of the present invention provides a stapler, including a fixing seat 1, a cutting assembly 2 and a cutting ring 3. The fixing seat 1 includes a seat body 11 and a connecting rod 12. The seat body 11 has a first end and a second end opposite to each other. The fixing seat 1 has an accommodating space 111 inside. The accommodating space 111 is open on one side near the first end of the connecting rod 12, and the other side of the accommodating space 111 is closed. The connecting rod 12 is connected to the second end of the seat body 11.

[0027] The cutting ring 3 is located on the outer circumferential surface of the base 11. The cutting component 2 is slidably connected to the connecting rod 12. The cutting component 2 can switch between a cutting position and a non-cutting position. When the cutting component 2 switches to the cutting position, the cutting ring 3 can be cut to provide a feedback signal. In this embodiment, the cutting position refers to the position where the cutting ring 3 is cut, and the non-cutting position corresponds to the cutting position. The accommodating space 111 is used to place the glans penis. The accommodating space 111 is arc-shaped. The fixing base 1 can bind excess tissue. During the switching between the cutting position and the non-cutting position, the cutting component 2 of the stapler can cut the tissue. The specific cutting steps of the cutting component 2 are as follows: during the process of the cutting component 2 moving from the non-cutting position to the cutting position, the cutting component 2 will first cut the tissue (foreskin), and then further cut the cutting ring 3. When the cutting ring 3 is cut, feedback signals such as vibration and sound are transmitted to the doctor, so that the doctor can promptly confirm whether the cutting is in place, avoid misjudgment, and enhance the safety and controllability of the surgery. In other embodiments, the cutting steps of the cutting component 2 can be that the cutting of tissue and the cutting of the cutting ring 3 are performed simultaneously. The cutting assembly 2 includes a movable push rod 21 and an annular cutting blade 22 mounted on the top of the movable push rod 21. The movable push rod 21 is sleeved on the outer periphery of the connecting rod 12 and can slide on the connecting rod 12, allowing the annular cutting blade 22 to switch between a cutting position and a non-cutting position, thereby cutting the tissue and the cutting ring 3. The stapler may also have a hemostatic function, that is, closing blood vessels while cutting to reduce bleeding. While cutting the tissue, the stapler is also responsible for anastomosing the tissue, that is, connecting the tissue edges after cutting. The stapler also has a staple cartridge 10. During the process of moving to the cutting position, the annular cutting blade 22 can cut the tissue and the cutting ring 3 while cutting the staples in the staple cartridge 10 into the tissue (the uncut tissue portion), so that the staples cooperate with the staple grooves on the fixation seat 1 to stop bleeding, complete the operation, and suture the tissue to achieve hemostasis. In one embodiment, a part of the structure of the annular cutting blade 22 is used to cut the tissue and the cutting ring 3, and another part of the structure is used to connect the staples in the staple cartridge 10.

[0028] In one embodiment, the first end of the base 11 is provided with a flange 13, and a first groove 4 is formed between the flange 13 and the fixing base 1. The cutting ring 3 is engaged in the first groove 4. In this embodiment, the cutting ring 3 is annular. The cutting ring 3 is not limited to any structure with the same function, such as U-shaped or O-shaped. As long as the cutting ring 3 can emit sound and transmit sensory signals such as vibration to the surgeon, it is within the protection range. It can effectively transmit sensory or auditory information to the surgeon during the operation to indicate that the cutting and suturing has been completed. The engaging design of the cutting ring 3 ensures the stability of the cutting ring 3 during the cutting process, thereby improving the accuracy of the operation. By engaging the cutting ring 3 with the groove, it is possible to prevent the cutting ring 3 from accidentally shifting during the operation, thereby reducing the surgical risk.

[0029] In one embodiment, the stapler further includes a baffle 6, which is installed in a first groove 4 and has a second groove 5 in which the cutting ring 3 is engaged. In this embodiment, the baffle 6 is made of metal and is preferably integrally molded with the fixation base 1. The integrally molded structure of the metal baffle 6 (injection molded with the fixation base 1) provides higher durability and stability because it reduces seams between components and potential points of failure. The presence of the baffle 6 prevents further cutting by the cutting blade, avoiding accidental damage to surrounding tissues, thereby improving the safety of the surgery. Because the baffle 6 provides additional stability and protection against accidental cutting, the surgeon can operate with more confidence and speed, thereby improving surgical efficiency. At the same time, the cutting ring 3 is engaged in the second groove 5 of the baffle 6. This design ensures the correct positioning and stability of the cutting ring 3, which helps to improve the accuracy of cutting.

[0030] In one embodiment, the stapler further includes a baffle 6, which is installed in the first groove 4, and a second groove 5 is formed between the baffle 6 and the seat 11, with the cutting ring 3 engaged in the second groove 5. Unlike the aforementioned embodiments, in this embodiment, the second groove 5 is formed jointly by the baffle 6 and the seat 11.

[0031] In one embodiment, the baffle 6 includes a first connecting segment 61 and a second connecting segment 62 connected together, the first connecting segment 61 being located inside the first groove 4 and the second groove 62 being located outside the first groove 4;

[0032] The first connecting segment 61, the second connecting segment 62, and the seat 11 form the second groove 5. In this embodiment, the baffle 6 is stepped, with the first connecting segment 61 located inside the first groove 4 and the second connecting segment 62 located outside the first groove 4. This arrangement helps to control the cutting depth and position more precisely. The presence of the baffle 6 not only helps to prevent the cutter from over-cutting and reduce the risk of damage to surrounding healthy tissue, but also provides additional fixation and protection for the cutting ring 3 by forming the second groove 5 together with the seat 11, thereby improving the safety of the operation.

[0033] In one embodiment, the cutting ring 3 includes a connected support portion 31 and a weak portion 32. The thickness of the support portion 31 is greater than the thickness of the weak portion 32. When the cutting assembly 2 is in the cutting position, the weak portion 32 can be cut to provide a feedback signal. In this embodiment, the direction from the first end to the second end of the seat 11 is parallel to the thickness direction of the cutting ring 3. The cutting ring 3 consists of two parts: the support portion 31 provides structural support, while the weak portion 32 is designed to break easily under stress. The support portion 31 is thicker than the weak portion 32 to ensure that the weak portion 32 breaks first under the cutting force, thereby achieving the breakage of the cutting ring 3. The breakage of the weak portion 32 provides a clear cutting point, helping to prevent over-cutting and unnecessary harm to the patient. By designing the weak portion 32, once the weak portion 32 breaks, clear feedback can be immediately provided to the doctor, indicating that the cutting has been completed.

[0034] In one embodiment, the cutting ring 3 has a third end and a fourth end opposite to each other, and the direction from the first end to the second end of the seat 11 is parallel to the direction from the third end to the fourth end of the cutting ring 3;

[0035] The cutting ring 3 has an opening groove 33, which is open on one side near the third end of the cutting ring 3 and closed on the other side. A weak portion 32 is formed between the bottom of the opening groove 33 and the fourth end of the cutting ring 3. In this embodiment, the third end of the cutting ring 3 can be the end near the cutting component 2 or the end away from the cutting component 2. The design of the weak portion 32 makes the cutting ring 3 easy to break during cutting, thus providing a clear feedback signal to the doctor that the cutting is complete. The design of the support portion 31 and the weak portion 32 of the cutting ring ensures that the ring maintains sufficient strength in the non-cutting area, while being easy to break in the cutting area. This ensures the smooth cutting process while maintaining the overall structural stability.

[0036] In one embodiment, the stapler further includes a fixed housing 7, the interior of which has a cavity 71. The seat 11, connecting rod 12, and cutting assembly 2 are all disposed within the cavity 71. In this embodiment, the fixed housing 7 forms a cavity 71 space within itself to accommodate the key components of the stapler. By integrating all the key components within the cavity 71 of the fixed housing 7, the stapler can be made more compact, easier to operate and carry. The cavity 71 design within the fixed housing 7 helps to integrate the components of the stapler, providing better protection and stability, while also simplifying surgical procedures and improving the safety and efficiency of the surgery.

[0037] In one embodiment, the stapler further includes a drive assembly 8, which is mounted on the fixed housing 7 and connected to the cutting assembly 2. The drive assembly 8 is used to drive the cutting assembly 2 to reciprocate between a cutting position and a non-cutting position. In this embodiment, the drive assembly 8 is mounted on the fixed housing 7, forming a complete mechanical system with the housing. The drive assembly 8 is connected to the cutting assembly 2 (movable push rod 21) via mechanical connections (such as a rotary positioning pin 83, a firing return spring 82, etc.) to achieve precise control of the cutting assembly 2. The drive assembly 8 includes a rotary positioning pin 83, a firing return spring 82, and a movable handle 81. The movable handle 81 is fixed by the rotary positioning pin 83. The movement of the cutting assembly 2 is controlled by the operation of the handle. The movable handle 81 is fixed by the rotary positioning pin 83. By squeezing one end of the movable handle 81, the other end of the movable handle 81 is pushed forward, which pushes the top body of the movable push rod 21 to slide forward, so that the annular blade on the top body and the anastomosis staples on the staple cartridge 10 cut into the tissue. Then, through the fixed bell-shaped glans seat (seat body 11) anvil ring and anvil groove structure, the annular blade cuts the tissue and cuts the anvil ring (cutting ring 3) to produce vibration or sound. The anastomosis staples close the tissue. After the cutting is completed, the movable handle 81 moves to the initial position (non-cutting position) under the action of the firing return spring 82. The design of the drive component 8 allows the surgeon to control the cutting component 2 with simple operations (such as squeezing the movable handle 81), simplifying the surgical procedure. The reciprocating movement of the drive component 8 allows for precise control of the cutting component 2's movement between the cutting and non-cutting positions, improving surgical accuracy. When the cutting component 2 is driven to the cutting position, the fracture of the weak point 32 provides immediate feedback signals, such as vibration or sound, informing the surgeon that the cutting is complete. The presence of the drive component 8 allows the surgeon to better control the cutting depth and force, reducing damage to surrounding tissues and improving surgical safety. Direct observation through the observation window 9 reduces surgical errors and improves surgical outcomes. Especially during delicate procedures, the surgeon can operate more precisely through the observation window 9, thus reducing the risk of postoperative complications such as bleeding, tissue damage, and infection.

[0038] In one embodiment, the fixed outer shell 7 is provided with an observation window 9, through which the operating environment inside the cavity 71 can be observed. In this embodiment, the top of the movable push rod 21 is provided with a light-transmitting structure (observation window) corresponding to the observation window 9. Through the observation window 9, the doctor can directly observe the situation inside the cavity 71 during the operation, including the operating environment of the seat 11, connecting rod 12 and cutting assembly 2, thereby improving the accuracy and safety of the operation. The doctor can directly see the cutting status of the cutting ring 3 and the closure effect of the anastomosis staples. At the same time, visual, auditory and sensory feedback is provided to the surgeon, which can enhance the surgeon's confidence during the operation.

[0039] According to the anastomosis device provided in this embodiment, the cutting component 2 can precisely control the cutting timing by switching between the cutting position and the non-cutting position, reducing errors during the surgical process. When the cutting ring 3 is cut, a clear feedback signal is provided, allowing the operator to promptly confirm whether the cutting component 2 has made the cut, avoiding misjudgment and enhancing the safety and controllability of the surgery. The sliding connection design between the cutting component 2 and the connecting rod 12 allows the surgeon to easily control the position of the cutting component 2 and achieve rapid switching. Because the cutting component 2 can quickly switch to the cutting position, and the cutting ring 3 provides immediate feedback, this helps to improve the efficiency of the surgery.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
