[0055] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0056] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0057] In the present application, unless otherwise specified, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application.

[0058] In order to solve the problem that the existing technology adopts an integrated design for the nail abutting seat 11' and the fixing rod 12', and the fixing rod 12' is directly connected with the adjusting knob of the shell assembly, so that the length of the nail abutting seat assembly is too long, and the surgical efficiency is affected. Therefore, the present application provides an anastomat.

[0059] The present application will be described in further detail below in combination with the drawings and specific embodiments.

[0060] As shown in the drawings, one embodiment of the present application provides an anastomat, which comprises a nail abutting seat assembly 1 and a shell assembly 2. Figures 2-11

[0061] The nail abutting seat assembly 1 comprises a nail abutting seat 11 and a fixing rod 12 arranged on one side of the nail abutting seat, and the two form a stable integrated structure.

[0062] The shell assembly 2 has a containing cavity and a mounting rod 21 arranged in the containing cavity, and the end of the fixing rod 12 away from the nail abutting seat is connected with the first end 211 of the mounting rod 21 through a buckle structure 3. The buckle structure 3 is designed ingeniously, which not only ensures the stability of the connection, but also facilitates the doctors to quickly and simply assemble and disassemble during the operation, greatly improving the efficiency and safety of the operation.

[0063] ​In this way, the size of the nail seat 11 and the fixed rod 12 can be designed to be smaller, improving the work efficiency when fixing the glans penis into the accommodating groove 111 of the nail seat 11 and fixing the foreskin tissue onto the fixed rod 12. Then, the fixed rod 12 can be connected with the mounting rod 21 through the buckle structure 3 to complete the entire operation, improving the work efficiency and safety of the entire operation.

[0064] Further, in order to optimize the connection structure, as shown in Figure 5 and Figure 6 , a mounting groove 121 is specially designed on the end face of the end of the fixed rod 12 away from the nail seat 11. The shape and size of the groove are just right, and can stably accommodate the first end 211 of the mounting rod 21 in the shell assembly 2.

[0065] The design of the buckle structure 3 is also unique, as shown in Figure 5 , which is composed of two parts, the elastic piece 31 and the flange 32. The elastic piece 31 is ingeniously arranged on the groove side wall of the mounting groove 121, and the flange 32 is arranged on the side wall of the mounting rod 21 and located near the first end 211. When the first end 211 is smoothly inserted into the mounting groove 121, the elastic piece 31 will immediately tightly buckle with the flange 32 to form a connection that is both firm and convenient to disassemble.

[0066] In order to further improve the buckle structure 3, as shown in Figure 7 and Figure 8 , an avoidance hole 1211 can be carefully designed on the groove side wall of the mounting groove 121. The shape and position of the avoidance hole 1211 are precisely calculated to ensure that the elastic piece 31 can perfectly fit into it. The avoidance hole 1211 includes oppositely arranged first and second hole walls, providing stable support for the elastic piece 31. The design of the elastic piece 31 is also ingenious, consisting of two parts, the extension 311 and the first boss 312. The extension 311 extends from one of the first or second hole walls to the other, and the first boss 312 is firmly arranged at the end of the extension 311 and protrudes towards the inside of the mounting groove 121, as shown in Figure 6 . Such a design not only enhances the stability of the buckle structure 3, but also makes the entire connection more firm and reliable.

[0067] Preferably, in order to simplify the production process, the elastic piece 31 and the groove wall of the mounting groove 121 can be designed as an integral structure. In the actual manufacturing process, we only need to easily form the elastic piece 31 on the groove wall of the mounting groove 121 through a simple stamping process, which not only saves costs, but also improves production efficiency.

[0068] Further, in the design of the flange 32, we have made a clever design. Returning to the best display in Figure 6 , the flange 32 not only extends towards the first end 211, but also closely matches the first end 211 to form a second boss 212 together. The shape and size of this second boss 212 are perfectly matched with the first boss 312. When the first end 211 is inserted into the mounting groove 121, the first boss 312 will be firmly clamped with the second boss 212 to form a stable and reliable connection.

[0069] Understandably, when the first boss 312 is clamped with the second boss 212, that is, the flange 32 and the first boss 312 achieve a clever clamping fit, this design not only enhances the stability of the connection, but also makes the entire structure more compact and reasonable.

[0070] The mounting rod 21 has a second end 213 opposite the first end 211. The second boss 212 gradually increases in cross-sectional area in the direction towards the second end 213, corresponding to Figure 6 When the mounting rod 21 is inserted into the mounting groove 121, the second boss 212 gradually increases in cross-sectional area in the direction from left to right in Figure 6 , perpendicular to the axial direction of the mounting rod 21. This design not only enhances the structural strength of the second boss 212, but also makes the entire mounting rod 21 more smooth during insertion and removal, further improving user experience.

[0071] In order to further enhance the effect of fixing the foreskin, referring to Figures 9-10 , a plurality of anti-skid protrusions 122 can be specially provided on the side wall of the fixing rod 12 near the position of the nail seat 11. These anti-skid protrusions 122 are regularly shaped and evenly distributed, and they can effectively increase the friction between the fixing rod 12 and the foreskin tissue, so as to ensure that the foreskin tissue can be stably fixed on the fixing rod 12 during the operation, without any sliding.

[0072] Considering the stability and convenience of actual use, preferably, the design of the anti-skid protrusions 122 can be optimized. Specifically, referring to Figure 10 , the anti-skid protrusions 122 can be provided along the entire circumference of the fixing rod 12, forming a continuous ring structure. This ring design not only improves the anti-skid effect, but also ensures that the foreskin tissue can be firmly fixed on the fixing rod 12 at any angle, enhancing the reliability and safety of the operation.

[0073] Further, the design of the nail seat 11 fully considers the needs of actual surgical operation. On the side facing away from the fixing rod 12, the nail seat 11 is cleverly provided with a receiving groove 111. Referring to Figure 2 and Figure 5As shown, the accommodating groove 111 is carefully shaped and sized to perfectly fit the glans penis, providing great convenience for the operation. In actual operation, the surgeon only needs to position the glans penis in the accommodating groove 111, then wrap the prepuce tissue around the nail seat 11, and fix it on the fixing rod 12.

[0074] Further reference is made to Figure 5 As shown, the four peripheral edges of the nail seat 11 are also designed with arc-shaped flanges. This detail ensures that the prepuce tissue wrapping the nail seat 11 will not be scratched, further improving the safety of the operation and the comfort of the patient.

[0075] In the design of the mounting rod 21, particular attention is paid to its versatility and ease of operation. The mounting rod 21 has a second end 213 arranged opposite the first end 211, which design makes it possible for subsequent installation and adjustment. In addition, the housing assembly 2 also includes a tubular housing 22 and an adjustment knob 23.

[0076] The cleverness of the adjustment knob 23 is that at least part of it can pass through one end of the tubular housing 22 and pivot inside the tubular housing 22. Such a design allows the surgeon to easily make various adjustments by rotating the adjustment knob 23 during the operation.

[0077] At the same time, the mounting rod 21 passes into the adjustment knob 23 from the other end of the tubular housing 22, and the second end 213 of the mounting rod 21 is connected with the adjustment knob 23 by screw thread. The outer side of the side wall of the second end 213 is provided with external threads 2131, and the inner side of the adjustment knob 23 is provided with internal threads. The advantage of this connection is that when the surgeon rotates the adjustment knob 23, the adjustment knob 23 will rotate relative to the mounting rod 21. Due to the action of the threads, this rotation will be converted into the movement of the mounting rod 21 along its axial direction. In turn, the movement of the mounting rod 21 will drive the nail seat assembly 1 connected thereto to move along its axial direction. Such a design not only makes the adjustment during the operation more accurate and convenient, but also greatly improves the practicality and flexibility of the entire surgical instrument.

[0078] In order to ensure the stable rotation of the adjusting knob 23 in the tubular shell 22 and prevent the adjusting knob 23 from falling off, a special assembly groove 231 is designed on the side wall of the adjusting knob 23. The assembly groove 231 extends along the circumference of the adjusting knob 23 and forms a complete closed loop structure. Correspondingly, an annular elastic protrusion (not directly shown in the figure) that perfectly matches the assembly groove 231 is arranged on the inner side of the side wall of the tubular shell 22. The annular elastic protrusion can be closely and slidably arranged in the assembly groove 231, which not only ensures the smooth rotation of the adjusting knob 23 but also effectively prevents the adjusting knob 23 from accidentally falling off during work, thereby improving the reliability and safety of the entire device.

[0079] In summary, the embodiments of the present application achieve the following technical effects:

[0080] The size of the nail abutting seat 11 and the fixing rod 12 can be designed to be smaller, thereby improving the operation efficiency when fixing the glans penis into the accommodating groove 111 of the nail abutting seat 11 and fixing the foreskin tissue on the fixing rod 12. Then, the fixing rod 12 and the mounting rod 21 can be connected through the buckle structure 3 to complete the entire operation, thereby improving the working efficiency and safety of the entire operation.
