Embodiment Construction

[0022] Referring to Fig. 1, a negative pressure suction pipe 1 is conventionally arranged, the front end of the negative pressure suction pipe 1 is a suction head 2, and the tail is communicated with a negative pressure drainage bottle 3.

[0023] In this embodiment, in the negative pressure suction device pipeline 1, the reaming product intercepting device 4 is arranged in series, and the reaming product flowing through the reaming product intercepting device 4 is intercepted during the drainage process, so as to realize the recycling of the reaming product .

[0024] Referring to Fig. 2, in the specific implementation, the reaming product intercepting device 4 is composed of a detachable end cover 41 and a cylinder 42 to form a cylindrical cavity, and a filter cartridge 43 for blocking the passage of the reaming product is arranged in the cylindrical cavity , The filter cartridge 43 is connected by a filter cartridge bracket arranged in the cylinder body 42 . One side of th...

Abstract

A reaming product taking device through a negative pressure extractor pipeline adopts the negative pressure extractor pipeline. The front end of the negative pressure extractor pipeline is a sucker, and the tail is communicated with a negative pressure drainage bottle. The device is characterized in that the negative extractor pipeline is provided with a reaming product cut-off device in series. The invention can realize the recovery of the reaming product passing through the negative pressure extractor pipeline, and the reaming product can be used effectively in the internal fixation with nail in marrow, thus healing the fracture.

Description

technical field [0001] The invention relates to a medical device, more specifically to a medical device used in intramedullary nail fixation for the treatment of limb long tubular bone fractures. Background technique [0002] The problem of fracture healing has always been a difficult problem for orthopedic surgeons, especially the increase in serious and complex fractures caused by modern transportation and construction has added difficulty to fracture healing. Fractures of the femur, tibia, and humerus are the most widely used bones for intramedullary nailing. Among them, tibial fractures, delayed bone union, nonunion, and bone defects after fractures require bone grafting. [0003] Modern medicine has shown that reamed bone debris can induce new bone formation and is also beneficial to fracture healing. At present, the commonly used bone grafts include autologous iliac crest, allogeneic bone, xenograft bone and artificial bone. Among them, the method of autologous bone ...
