One end of thehandle 10 is provided with afixing portion 101, and thehandle 10 is provided with adriving device 40. One end of theopening assembly 20 is connected with thedriving device 40 through thefixing part 101, and the other end extends outside thehandle 10; Thespreader assembly 20 is driven to force thespreader assembly 20 to drive theannular blades 30 to radially open or close.

本发明提供的保乳手术腺瓣固定刀，可以在医护人员使用时用手抓持手柄10，然后控制驱动装置40，使得驱动装置40驱动撑开组件20并带动环形刀片30张开或合拢，针对不同的肿瘤组织可以将环形刀片30进行调节至不同的径向尺寸，从而抵贴至肿瘤组织上进行固定并进行切割，使得在保乳手术中的肿瘤组织固定更稳定，切割效果更好且避免了造成切割残留，使得手术效果更好。In the breast-conserving surgery glandular flap fixing knife provided by the present invention, the medical staff can hold thehandle 10 by hand, and then control thedriving device 40, so that thedriving device 40 drives theopening assembly 20 and drives theannular blade 30 to open or close, For different tumor tissues, theannular blade 30 can be adjusted to different radial sizes, so as to abut the tumor tissue for fixation and cutting, so that the tumor tissue fixation in breast-conserving surgery is more stable, the cutting effect is better, and the It avoids cutting residues and makes the surgical effect better.

具体的，撑开组件20包括推杆201、张合件202及限位杆203，推杆201的一端连接于驱动装置40；张合件202的顶部枢转连接于推杆201的另一端，且底部枢转连接于环形刀片30；限位杆203为可伸缩结构，且限位杆203顶部枢转连接于固定部101，底部滑动连接于张合件202外侧；其中，推杆201用于带动张合件202，以迫使张合件202与环形刀片30共同张开或合拢。Specifically, theopening assembly 20 includes apush rod 201, atension member 202 and alimit rod 203. One end of thepush rod 201 is connected to the drivingdevice 40; the top of thetension member 202 is pivotally connected to the other end of thepush rod 201. And the bottom is pivotally connected to theannular blade 30; thelimit rod 203 is a retractable structure, and the top of thelimit rod 203 is pivotally connected to the fixingportion 101, and the bottom is slidably connected to the outside of thetension member 202; wherein, thepush rod 201 is used for The tensioningmember 202 is driven to force the tensioningmember 202 and theannular blade 30 to open or close together.

在本实施例中，在撑开组件20将环形刀片30撑开时，驱动装置40带动推杆201呈直线运动，使得推杆201伸出固定部101并推动张合件202的两端转动，当张合件202枢转至与环形刀片30平齐时，限位杆203被拉伸至最长，并且环形刀片30径向尺寸最大；在驱动装置40带动推杆201缩回固定部101时，推杆201拉动张合件202使得张合件202进行转动，张合件202合拢时带动环形刀片30共同合拢，当环形刀片30完全合拢时则径向尺寸最小，并且限位杆203被拉伸至最短，由此，可以理解的是，在使用时，环形刀片30的径向尺寸可以任意调节，从而在保乳手术中，可以针对不同的肿瘤组件调节至不同尺寸进行固定，保证在切割过程中的稳定。In this embodiment, when theannular blade 30 is opened by the openingassembly 20, the drivingdevice 40 drives thepush rod 201 to move linearly, so that thepush rod 201 extends out of the fixingportion 101 and pushes the two ends of thetension member 202 to rotate. When the tensioningmember 202 is pivoted to be flush with theannular blade 30, thelimit rod 203 is stretched to the longest, and the radial dimension of theannular blade 30 is the largest; when the drivingdevice 40 drives thepush rod 201 to retract the fixingportion 101 , thepush rod 201 pulls the tensioningmember 202 to make thetensioning member 202 rotate. When the tensioningmember 202 is closed, it drives theannular blades 30 to close together. When theannular blades 30 are completely closed, the radial dimension is the smallest, and thelimit rod 203 is pulled Therefore, it can be understood that the radial size of theannular blade 30 can be adjusted arbitrarily during use, so that in breast-conserving surgery, it can be adjusted to different sizes for different tumor components for fixation, ensuring that the cutting stability in the process.
