Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a circumcision stapler. Background Art

[0002] At present, manual circumcision and circumcision staplers are usually used to treat prepuce hyperplasia. Manual circumcision uses manual cutting and suturing. Although there are many ways, the postoperative cutting edge condition depends entirely on the surgeon's level and skills. The foreskin incision is often uneven and unsightly, which does not meet the surgeon's requirements, and the operation time is long. Although the existing circumcision stapler has the characteristics of smooth incision, short operation time, and easy operation, the existing circumcision stapler has only one fixed nail forming height when in use. When the nail forming height is too small, over-firing will occur, excessive squeezing of the tissue is performed, which is not conducive to postoperative recovery and growth. When the nail forming height is too large, bleeding will occur after the operation, requiring the doctor to perform subsequent hemostasis operations, which is relatively complicated and causes the anastomosis to be unsightly. In addition, the existing foreskin stapler is prone to misalignment when in use, and the positioning accuracy is poor, affecting the surgical effect.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a circumcision stapler [CN201711349566.5], which includes a shell, at least one firing handle rotatably connected to the shell, and a stop mechanism; wherein, when the stop mechanism is in a first state and the firing handle rotates and abuts the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a first angle, and when the stop mechanism is in a second state and the firing handle rotates and abuts the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a second angle, and the first angle is different from the second angle.

[0004] The above solution solves the problem that the nail forming height is fixed and difficult to adjust flexibly in the prior art to a certain extent. However, the solution still has many shortcomings, such as: easy firing misalignment and poor positioning accuracy, which affects the surgical effect. Summary of the invention
