Microendoscopic soft tissue suture guiding device and microendoscopic soft tissue suture guiding method

Abstract

The invention relates to a microendoscopic soft tissue suture guiding device and a microendoscopic soft tissue suture guiding method. The microendoscopic soft tissue suture guiding device comprises a guide pin, a guide body and a hollow pin, wherein one end of the guide pin is provided with a pinpoint, and the other end of the guide pin is fixedly arranged in one end of the guide body; an included angle which is smaller than 90 degrees is formed between the other end of the guide pin and the guide body; the middle of the guide body is provided with a guide pipe; the hollow pin penetrates through the interior of the guide pipe; one end of the hollow pin is provided with a push handle, and a pinpoint at the other end of the hollow pin penetrates out of the pinpoint of the guide pin along the guide pipe. The device and the method can be used for simplifying the microendoscopic suture operation performed for treating soft tissue lacerated wounds; when puncturation or pin insertion is performed upward from an endoscope blind zone below a soft tissue, the device can be used for accurately locating a puncturation position, avoiding secondary soft tissue damages caused when trial pin insertion is performed as the puncturation position is difficult to locate; the device is simple in structure, convenient to operate, economical and practical, and convenient to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of medical soft tissue repair, in particular to an endoscopic soft tissue suturing guide device and method. Background technique [0002] Soft tissue laceration is a common disease in sports injuries, such as meniscus tear of knee joint and triangular fibrocartilage complex (TFCC) tear of wrist joint. With the development and updating of endoscopic equipment, the repair of soft tissue has been transitioned from open surgery to minimally invasive surgery. The two-dimensional image displayed by the endoscope cannot fully display the three-dimensional space of the joint capsule, and there are often multiple blind spots, which increases the difficulty of soft tissue repair. Due to the difficulty in locating the puncture site, tentative acupuncture often causes soft tissue damage again, affecting the healing ability of soft tissue. Repeated attempts will prolong the operation time and increase the pain of patien...

Problems solved by technology

The two-dimensional image displayed by the endoscope cannot fully display the three-dimensional space of the joint capsule, and there are often multiple blind spots, which increases the difficulty of soft tissue repair

Due to the difficulty in locating the puncture position, the soft tissue is often damaged again during the tentative needling, which affects the healing ability of the soft tissue. Repeated attempts will prolong the operation time and increase the pain of the patient, making it difficult for various high-tech operations to be carried out in primary hospitals.
