背景技术Background technique
腹部手术的施行，如肝部分切除术、胰十二指肠切除术、脾切除术及门奇静脉断流术，离不开腹部牵开器的使用。虽然现有的腹部牵开器已经替代了以往第二、第三助手的人力牵拉，节约了一定的时间和体力，但它们仍存在着一定的缺陷，如拉钩的大小、形状固定，限制了主刀医生根据手术需要和手术视野的不同对牵开器的角度和方位的调整，使得手术视野的显露有限且调整不便；部分牵开器组成部件较多，框架较大，不仅安装复杂而且阻碍手术操作，给术者带来了一定的困扰。The implementation of abdominal surgery, such as partial hepatectomy, pancreaticoduodenectomy, splenectomy and portal azygos devascularization, cannot do without the use of abdominal retractor. Although the existing abdominal retractors have replaced the manual pulling of the second and third assistants in the past, saving a certain amount of time and physical strength, they still have certain defects, such as the fixed size and shape of the retractors, which limit the The surgeon adjusts the angle and orientation of the retractor according to the needs of the operation and the difference in the surgical field of view, which makes the exposure of the surgical field of view limited and inconvenient to adjust; some retractors have many components and a large frame, which is not only complicated to install but also hinders the operation The operation has brought some troubles to the operator.
同时，由于在手术中，一个暴露良好的手术视野对任何一个手术过程都是至关重要的。而现在用于手术中的暴露器械手式拉钩是最常用的，而使用拉钩牵拉时，由于拉钩与手术切口边缘多为点接触，因此，通常每一个拉钩只能牵拉出一个三角形的手术视野，要达到较开阔的手术视野，需要多只手用多个拉钩对手术切口边缘的多个点同时进行牵拉，而这样的操作却是费时费力、非常不方便。At the same time, because in surgery, a well-exposed surgical field of view is crucial to any surgical procedure. However, the hand-type retractors for exposed instruments used in surgery are the most commonly used. When pulling with retractors, since the retractors are mostly in point contact with the edge of the surgical incision, usually each retractor can only pull out a triangular shape. Field of view, in order to achieve a wider surgical field of view, it is necessary for multiple hands to simultaneously pull multiple points on the edge of the surgical incision with multiple retractors, but such an operation is time-consuming, laborious, and very inconvenient.
目前市场上虽有部分设备，然而这些设备均为零散的自制，致使器械在使用过程中均存在着牵开器调节性能较差，不能稳固固定，进而使得牵开时肌肉牵拉力较小，而且有时会因为牵开器过大影响手术视野，临床使用不便，费时费力，降低手术操作的稳定性，影响手术操作的顺利进行，降低手术效率，延长手术时间，不便手术操作，推广应用受限。Although there are some devices on the market at present, these devices are scattered and self-made, resulting in poor adjustment performance of the retractor during the use of the device, which cannot be firmly fixed, which in turn makes the muscle pulling force smaller when retracting. And sometimes because the retractor is too large, it affects the surgical field of view, which is inconvenient for clinical use, time-consuming and laborious, reduces the stability of the surgical operation, affects the smooth progress of the surgical operation, reduces the operation efficiency, prolongs the operation time, is inconvenient for the operation, and is limited in popularization and application. .
