Description

Technical Field

[0001] The invention belongs to the technical field of circumcision surgical instruments, and in particular relates to a circumcision kit. Background Art

[0002] The circumcision device is an auxiliary medical device used to assist surgeons in completing elastic coil positioning and ligation during circumcision surgery. In order to improve surgical efficiency and facilitate rapid alignment, the applicant has provided a series of patents such as CN202010969170.6 An automatic circumcision elastic wire ligation and anastomosis component and CN202010967380.1 A new type of elastic wire ligation foreskin cover component based on the actual needs of the surgical process. It can further simplify the circumcision surgery process and automate the coil positioning and ligation and other contents that are inconvenient for human operation. During the long-term application of the above-mentioned patented product, after analysis of user feedback, the following shortcomings still exist: the existing inner and outer ring structures have relatively fixed dimensions. When the foreskin is short or has poor elasticity, the foreskin cannot be pulled to fix the tightening area at the lower end of the inner ring, resulting in the operation being unable to be performed or difficult to operate. At the same time, the existing inner ring adopts a fully enclosed structure, resulting in full coverage of the top contact area. During docking, the contact between the patient's body and the instrument cannot be confirmed. When blockage and squeezing occur, they cannot be confirmed in time, which may lead to problems such as poor patient experience. At the same time, the existing operating mechanism is large in size, the internal action structure has a large stroke, and the fast-moving structure is prone to impacting the surgical operator, which is not conducive to the further promotion and application of the product.
