技术领域technical field
本实用新型涉包皮切割、缝合手术器械，尤其是涉及一种枪式结构包皮环形切割缝合器械。The utility model relates to a foreskin cutting and suturing surgical instrument, in particular to a foreskin circular cutting and suturing instrument with a gun-type structure.
背景技术Background technique
随着医疗科技有发展和临床验证，包皮环切缝合术的切割缝合原理逐渐被临床学术界所接受。包皮环切缝合器与传统包皮切割手术相比，具有切割、缝合一步完成的优点，该方法具有手术快速，出血少，痛苦小，切割平整等优点。目前该类包皮环切缝合器，器身外型大致呈类似“红酒开酒器”结构。但该类产品因其力学结构设计存在缺陷，存在切割精准度低和手术质量和手术成功率偏低等缺陷。该类产品缺点总结归纳如下：With the development of medical technology and clinical verification, the cutting and suturing principle of circumcision and suture has gradually been accepted by the clinical and academic circles. Compared with the traditional circumcision operation, the circumcision stapler has the advantages of cutting and suturing in one step. This method has the advantages of fast operation, less bleeding, less pain, and smooth cutting. At present, this type of circumcision suturing device has a body shape roughly similar to a "red wine opener" structure. However, this type of product has defects such as low cutting accuracy, low surgical quality and low surgical success rate due to its mechanical structure design. The disadvantages of this type of product are summarized as follows:
1、该类产品切割缝合原理，主要由一双对称的击发手把，医生击发后，经推杆力传导，使环状切刀和缝合钉几乎同步推进，从而切断过长包皮并将缝合钉钉合至包皮上而实现切口缝合。通常医生用双手或单手击发手把，但无论怎样的握把姿势，都难以使分布于器身两侧的手把得以同步推进，即总有一侧手把先行推进，推杆重力偏移，最终导致环切刀轴心偏移，造成未能切割过线，需要医生再使用手术刀进行补刀切割完成，或直接切出刀砧以外的缝合钉位置，而导致手术失败或部份失败。1. The cutting and suturing principle of this type of product is mainly composed of a pair of symmetrical firing handles. After the doctor fires, the force of the push rod is transmitted to make the circular cutter and the staples advance almost synchronously, so as to cut off the overly long foreskin and staple the staples. Closed to the foreskin to achieve incision suturing. Usually the doctor uses both hands or one hand to fire the handle, but no matter what the grip posture is, it is difficult to advance the handles distributed on both sides of the body simultaneously, that is, one side of the handle always advances first, and the gravity of the push rod shifts. Eventually, the axial center of the circumcision knife deviates, resulting in failure to cut through the line, and the doctor needs to use a scalpel to complete the cut, or directly cut out the position of the staples other than the anvil, resulting in failure or partial failure of the operation.
2、并由于无切割深度限位装置，其击发的力度和切割深浅，完全由医生经验判断，常常出现切割过深，使切刀深深陷入刀砧内而无法拔出，或切割力过小，过长包皮无法切下，且无法再实施二次击发等现象，导致手术完全失败。2. Since there is no cutting depth limiting device, the firing force and cutting depth are completely judged by the doctor's experience. Often, the cutting is too deep, causing the cutting knife to sink deeply into the anvil and cannot be pulled out, or the cutting force is too small , the foreskin was too long and could not be cut, and the second shot could no longer be performed, which led to the complete failure of the operation.
3、目前该类产品的龟头帽与拉杆的连接，均是用塑料实现连接的，在切割过程中，连接部位由于承受持续切割力的冲压，连接部位常常出现断裂、损毁，无法进行手术或手术失败。3. At present, the connection between the glans cap and the pull rod of this type of product is realized by plastic. During the cutting process, the connection part is often broken and damaged due to the continuous cutting force, making it impossible to perform surgery or operations. fail.
并由于环切刀与塑料顶杆是通过热熔铆合方式进行熔接固定的，切割完成退刀时，铆合点脆裂脱落，使环切刀、包皮仍然嵌在刀砧上，陷入无法实现退刀的尴尬境地，从而导致手术失败或部份失败。And because the ring cutter and the plastic mandrel are welded and fixed by hot-melt riveting, when the cutting is completed and the knife is retracted, the riveting point is brittle and falls off, so that the ring cutter and the foreskin are still embedded on the anvil, and the retraction cannot be realized. The embarrassing situation of the knife, which leads to the failure or partial failure of the operation.
