[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figure 1 to Figure 4 As shown, the new circumcision stapler of the utility model comprises: a nail support bracket 1, a shell 2, a nail pusher nut 4, a nail pusher 5, a cutting knife rear seat 6, a cutting knife 7 and an adjusting nut 9; the cutting knife 7 is fixed to the front end of the cutting knife rear seat 6, and the cutting knife rear seat 6 is threadedly connected to the shell 2; the nail pusher 5 is located on the outside of the cutting knife 7 and is threadedly connected to the nail pusher nut 4, and the shell 2 axially fixes the nail pusher nut 4; the nail support bracket 1 is located on the inside of the shell 2, and the tail of the nail support bracket 1 is threadedly connected to the adjusting nut 9.

[0026] Specifically, the shell 2 is a cylindrical structure with a transparent shell design, which is convenient for medical staff to observe and has an avoidance groove to facilitate the installation of the nail pusher nut 4 and push it using a threaded structure. The shell 2 includes a nail pusher guide sleeve 21, a fan-shaped connecting plate 22, a threaded connecting sleeve 24, a hollow connecting plate 28 and a handle 26 connected in sequence.

[0027] There are several fan-shaped connecting plates 22 and they are distributed in a circular array. Specifically, four fan-shaped connecting plates 22 are provided. A clearance groove is formed at the gap between adjacent fan-shaped connecting plates 22. The clearance groove is opposite to the external threaded arc plate 52 at the tail of the nail pusher 5, so that the external threaded arc plate 52 and the nail pusher nut 4 are threadedly matched. Two annular limiting bosses 23 are provided on the outside of the fan-shaped connecting plate 22 to limit the axial movement of the nail pusher nut 4. The position of the nail pusher 5 can be adjusted by rotating the nail pusher nut 4 to realize the nail pushing function. The nail pusher nut 4 is rotated to cooperate with the nail pusher 5 to push and retract, and the use of a rotating propulsion structure is more stable.

[0028] Among them, the nail pusher 5 adopts a transparent design, and a nail pusher scale line 51 is provided on the outer circumference of the nail pusher 5. By observing the nail pusher scale line 51 corresponding to the upper end surface of the nail pusher nut 4, the moving distance of the nail pusher 5 can be known, the advancement progress of the nail pusher can be observed, and then it can be judged whether the suture nail at the front end of the nail pusher 5 has been pushed to the predetermined position.

[0029] The cutter back seat 6 includes an internal thread sleeve 61 and a stepped sleeve 62. The internal thread sleeve 61 is located outside the threaded sleeve 24 and the two are threadedly matched. The stepped sleeve 62 is located inside the threaded sleeve 24 and extends to the position of the cutter 7 to push the cutter 7 to move axially. At the same time, the tails of the internal thread sleeve 61 and the stepped sleeve 62 are connected as a whole. Through threaded matching, the cutter can be rotated to advance and retract, so that the cutter can be rotated for cutting.

[0030] Among them, the outer side of the threaded connection sleeve 24 is provided with a hollow connection plate 28, and the threaded connection sleeve 24 is connected to the handle 26 through a pair of hollow connection plates 28. At the same time, a cutting knife scale line 25 is provided on the hollow connection plate 28. By observing the cutting knife scale line 25 corresponding to the end face of the cutting knife rear seat 6, the moving distance of the cutting knife rear seat 6 can be known, and then the moving distance of the cutting knife 7 can be judged. The cutting knife scale line 25 is convenient for observing the advancement progress of the cutting knife.

[0031] like Figure 1 to Figure 4 As shown, the anvil bracket 1 includes a bowl portion and a rod portion. The front end bowl portion adopts an asymmetric height design, and a small vertical groove 11 is left next to the high end to prevent the frenulum from being cut when cutting the foreskin; the top outer ring and the bottom outer ring of the anvil bracket 1 are provided with an annular foreskin fixing groove 12 to facilitate the fixing of the foreskin; the tail end of the rod portion has a thread that cooperates with the thread of the adjusting nut 9; at the same time, the tail end of the rod portion is extended, and an anvil scale line 13 is left at the tail end of the rod portion to facilitate the observation of the thickness of the fixed foreskin.

[0032] Among them, a dowel seat guide tube 27 is provided inside the handle 26, and the tails of the two are connected; an internal spline is provided inside the dowel seat guide tube 27, and the internal spline cooperates with the external spline in the middle of the dowel seat bracket 1. The spline cooperation can prevent the dowel seat bracket 1 from rotating with the adjusting nut 9, thereby avoiding displacement of the foreskin and affecting the quality of the operation.

[0033] In addition, the handle 26 is designed to imitate human joints and has anti-skid grooves, which is more suitable for hand holding and prevents slipping. The adjusting nut 9 is connected to the housing and cooperates with the thread at the tail end of the anvil support bracket to lock the anvil support bracket.

[0034] This new type of circumcision stapler is the first of its kind in China. It adopts a threaded rotary propulsion method, making the propulsion method more stable. When cutting the foreskin, rotary cutting is used, making the cutting more efficient and stable, so that medical workers can use it with confidence.

[0035] The following is a brief description of the technical features of the new circumcision stapler of the utility model: 1. It adopts a rotary cutting design, which is a domestic first; 2. It adopts a transparent shell plus scale line design, which is a domestic first; 3. It adopts a new appearance design, which is a domestic first; 4. It combines various advantages to facilitate operation by medical staff.

[0036] In addition, the present invention combines the existing mature excellent technologies and makes innovative improvements on this basis. The cutting knife uses a rotary extrusion cutting method, which adds the function of rotary cutting on the basis of the original extrusion cutting, making the cutting more stable and effective, and reducing the burden on medical staff. Compared with the existing new circumcision staplers, the present invention is the first in China in terms of both appearance and structure.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
