Suction tube device used for orthopedic surgery

Abstract

The invention discloses a suction tube device used for orthopedic surgery. The suction tube device used for the orthopedic surgery comprises a suction tube and a negative-pressure tube, wherein the suction tube is connected with a suction apparatus head; the negative-pressure tube is connected with a negative-pressure bottle; a filter cavity is connected between the suction tube and the negative-pressure tube. The filter cavity consists of a filter screen cavity and a fragment storage cavity, wherein the opening of the filter screen cavity and the opening of the fragment storage cavity are connected with each other, and the filter screen cavity and the fragment storage cavity are respectively made of a transparent rubber material or plastic; the filter screen cavity is connected with the negative-pressure tube; a filter screen is arranged in the filter screen cavity; a conduit is arranged in the fragment storage cavity; the conduit extends from exterior of the bottom part of the fragment storage cavity to the outer end of the opening of the fragment storage cavity; and the suction tube is connected with one end of the conduit, which is located outside the bottom part of the fragment storage cavity. Thus, on one hand, blocking cannot be generated in the suction tube and the suction apparatus head, and bone fragments can be stored in the fragment storage cavity, and meanwhile, on the other hand, the fragments in the fragment storage cavity can be conveniently poured out; blood cannot flow back to the suction tube, and thereby, complications are effectively prevented from occurring.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a suction tube device for orthopedic surgery. Background technique [0002] Suction tube is one of the necessary tools in surgical operations. At present, the suction tubes used in most hospital operations are generally reusable metal suction tubes or disposable plastic suction tubes. Their structure is generally a straight-through circular tube, but this type of suction tube is easy to block when used in orthopedics, hand surgery and general surgery debridement, because bone debris and other tissues that are easy to block the duct are often produced in orthopedic surgery. Such as bone cement debris, osteophyte and bone tumor tissue. In order to prevent clogging, some suction heads are made round and have multiple filter holes on them to prevent the inhalation of bone debris. However, when the bone debris accumulates during the operation, it will still hinder...

Problems solved by technology

In order to prevent clogging, some suction heads are made round and have multiple filter holes on them to prevent the inhalation of bone debris. However, when the bone debris accumulates during the operation, it will still hinder the normal work of the suction head. interfere with the normal operation
