Therefore, the foreskin anastomat has great advantages in the circumcision.

However, the foreskin staplers currently in use suffer from the following problems: firstly, the existing foreskin anastomat (such as a 'business ring') is not used for one-time cutting in an operation, but needs a patient to carry the anastomat after the operation, and the foreskin incision is sleeved by 'pressurizing' for several days, so that the life of the patient after the operation is inconvenient, and the problems of foreskin edema, incision pain and the like are easily caused; secondly, when the foreskin is cut in the operation, the base part of the existing foreskin anastomat can shield part of the penis body and the glans part, so that a doctor cannot adjust the length of the foreskin or the frenulum which needs to be reserved under the direct vision condition and cannot accurately adjust the range of the foreskin excision, and therefore, the problems of insufficient safety and low accuracy of the operation are caused due to the possibility of misoperation of excessive or insufficient foreskin excision.

Furthermore, the above-mentioned holding device 10 may also provide for the circumferential fixation between the upper 21 and lower 22 anastomosis structures of the anastomosis device 20. Specifically, in another embodiment, the circumcision and circumcision instrument 1 further includes an upper coupling assembly 31 and a lower coupling assembly 32, wherein the upper coupling assembly 31 includes a first upper coupling unit 31a (as shown in fig. 1 and 3) disposed on the second clamping member 12 (the second adapting unit 124) and a second upper coupling unit 31b disposed on the second upper structure body 212, and the first upper coupling unit 31a and the second upper coupling unit 31b are engaged with each other to assemble the second upper structure body 212 on the second clamping member 12 and circumferentially fix the two.

In this embodiment, when the second clamping member 12 of the clamping device 10 is assembled to the first clamping member 11 to form the clamping assembly 15, the second upper structure body 212 assembled to the second clamping member 12 and the first upper structure body 211 assembled to the first clamping member 11 can pivot relative to the pivot joint 14, that is, the upper engaging structure 21 is pivoted relative to the pivot joint 14 as a whole, and the first upper structure body 211 is located at the position of the first position-limiting portion 2151 relative to the second upper structure body 212, in this state, the first clamping member 11 is forced or the first clamping member 11 and the third clamping member 13 are forced together, and the clamping assembly 15 and the third clamping member 13 are actuated to pivot relative to each other with the pivot joint 14 as the center, so as to drive the upper engaging structure 21 and the lower engaging structure 22 to move towards each other until the anastomosis device 20 is in a pre-operation state, for example, the second upper structure body 212 and the lower engaging structure 22 of the upper anastomosis structure 21 abut against each other, and the first upper structure body 211 is still located at the position of the first position-limiting portion 2151 (refer to the state shown in fig. 4) relative to the second upper structure body 212. As described above, in this state, there is no interaction between the upper and lower stapling elements 214 and 223, 213, and 222, which allows the surgeon to perform a pre-tightening procedure (e.g., using the pre-tightening ring 224) for the foreskin.

When the anastomosis device 20 is in the pre-operation state, the first clamping member 11 and the third clamping member 13 are continuously stressed, so that the second clamping member 12 and the first clamping member 11 are separated from each other, and the first clamping member 11 is actuated to further pivot relatively around the pivot member 14, so as to drive the first upper structure body 211 to move axially relative to the second upper structure body 212 in a direction approaching the lower anastomosis structure 22 (i.e. the first upper structure body 211 moves relative to the second upper structure body 212 from the first position-limiting portion 2151 in a direction of the second position-limiting portion 2152), until the anastomosis device 20 is switched from the pre-operation state to the operation state, that is, the first upper structure body 211 is located at the position of the second position-limiting portion 2152 relative to the second upper structure body 212 (refer to the state shown in fig. 5). As described above, in this state, the upper and lower anastomosis members 214, 223 cooperate to perform an anastomosis procedure with respect to the foreskin, and the upper and lower ring cutting members 213, 222 also cooperate to perform a ring cutting procedure with respect to the foreskin.

The second clamping member 12 of the clamping device is assembled to the first clamping member 11 to form a clamping assembly 15, so that the second upper structure body 212 of the anastomosis device and the first upper structure body 211 form a linkage action relationship.

The penis can respectively pass through the lower through channel and the upper through channel, the lower inosculation structure and the upper inosculation structure are coaxially assembled on the penis, and the glans part of the penis extends out of the upper through channel and is exposed.

By applying a force to the first clamping member 11 or applying a force to the first clamping member 11 and the third clamping member 13 simultaneously, the clamping assembly 15 and the third clamping member 13 are actuated to pivot relatively around the pivot 14, so as to drive the second upper structure body 212 to move along with the first upper structure body 211 in a direction approaching the lower anastomosis structure 22, until the anastomosis device 20 is in the pre-operation state. In this state, a part of the foreskin to be cut is clamped between the second upper structure body 212 and the lower anastomosis structure 22, and the upper anastomosis member 214 and the lower anastomosis member 223, and the upper ring cutting member 213 and the lower ring cutting member 222 are not affected, so that the doctor can perform an adjustment operation on the foreskin to be cut. It should be noted that, in this process, the present application may further include performing a pre-tightening fixing operation on the foreskin to be cut by using the anastomosis device 20, however, since the pre-tightening fixing operation can be implemented by various embodiments and is not directly related to the clamping device 10 of the present application, further description is omitted here to avoid obscuring the technical focus of the present application.

The acting force is continuously applied to the first clamping member 11 and the third clamping member 13, so that the second clamping member 12 and the first clamping member 11 are separated from each other, and the first clamping member 11 and the third clamping member 13 are further pivoted relative to each other with the pivot member 14 as the center, thereby driving the first upper structure body 211 to move axially relative to the second upper structure body 212 in the direction approaching the lower anastomosis structure 22 until the anastomosis device 20 is switched from the pre-operation state to the operation state, i.e. the upper anastomosis member 214 and the lower anastomosis member 223 cooperate to anastomosis the foreskin, and the upper incision member 213 and the lower incision member 222 cooperate to circumcise the foreskin, thereby completing the foreskin anastomosis and the circumcision operations.

In conclusion, the clamping device provided by the application utilizes the sectional type clamping function to control the switching of the anastomosis device between the pre-operation state and the operation state, thereby facilitating the execution of the foreskin anastomosis and the circumcision, realizing the purpose that a doctor can complete the operation by one-man operation, and effectively improving the safety of the operation.
