Description
Translated fromChinese技术领域technical field
本发明涉及医疗器械技术领域，更具体地说，涉及一种创伤骨科手术切口撑开器。The invention relates to the technical field of medical instruments, in particular to an incision spreader for traumatic orthopedic surgery.
背景技术Background technique
创伤骨科就是骨科学的一个细小的分支，面向的人群为各种创伤性疾病。比如上臂的骨折、下肢的骨折、脊柱的骨折以及其他部位的骨折等，所面临的人群主要是以各种骨折为主。Traumatology orthopedics is a small branch of orthopedics, which targets various traumatic diseases. For example, fractures of the upper arm, lower limbs, spine, and other parts of the body.
在创伤骨科手术时，需要将患者骨折处的皮肤表面切开，从而便于持刀医生对患者进行骨骼修复，在现有的骨科手术中，将皮肤肌肉切口后通常使用手术拉钩将皮肤肌肉向两边拉住，由此才可进一步开展手术，但是现有的手术拉钩在使用的过程中，一般都是通过医护人员手持手术拉钩将手术切口向两边拉开，从而导致需要至少两名医护人员进行操作，造成人力资源浪费的同时，还可能影响持刀医生的手术操作，同时，由于人体肌肉的收缩力度较大，导致在牵拉手术拉钩时较为吃力，甚至在长时间的手术时，需要替换医护人员牵拉手术拉钩，如果采用设备代替人手，则导致较与人手的灵活度较差，使得撑开的方向不能准确的垂直于手术切口，从而导致切口在撑开时设备贴近切口的一侧距离较长，进而使得距离较短的一侧观察不够全面，继续撑开时，则可能导致对患者身体组织造成损伤。In traumatic orthopedic surgery, it is necessary to incise the skin surface of the patient's fracture, so that the doctor holding the knife can repair the patient's bone. In the existing orthopedic surgery, the skin and muscle are usually incised with surgical retractors to both sides. Only then can the operation be carried out further, but in the process of using the existing surgical retractor, the surgical incision is generally opened to both sides by the medical staff holding the surgical retractor, which requires at least two medical staff to operate , while causing waste of human resources, it may also affect the surgical operation of the doctor holding the knife. At the same time, due to the strong contraction of human muscles, it is more difficult to pull the surgical retractor, and even in a long operation, it is necessary to replace the medical staff. If the staff pulls the surgical retractor, if the device is used instead of the human hand, it will result in poorer flexibility than the human hand, so that the direction of stretching cannot be accurately perpendicular to the surgical incision, resulting in the distance between the equipment and the side of the incision when the incision is stretched. It is longer, so that the observation on the side with a shorter distance is not comprehensive enough, and when it continues to be stretched, it may cause damage to the patient's body tissue.
基于此，本发明设计了创伤骨科手术切口撑开器，以解决上述问题。Based on this, the present invention designs a trauma orthopedic surgery incision spreader to solve the above problems.
