A filter screen is installed between the top of the side of the slag hopper close to the bellows joint. The filter screen of the suction device with this structure is not easy to be blocked, and can work continuously for a long time.

Description

An orthopedic attractor

technical field

The utility model belongs to the field of medical equipment, in particular to an aspirator structure used in orthopedics.

Background technique

Aspirator is one of the necessary tools in orthopedic surgery. At present, the aspirator used in most hospital operations is generally a metal aspirator used repeatedly or a disposable plastic aspirator. Their structure is generally a straight-through circular tube, but this type of suction 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 pipeline 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 the normal work of the suction head. hinder the normal operation of the operation.

Contents of the invention

The technical problem to be solved by the utility model is to provide an orthopedic aspirator with a reasonable structure, which can effectively filter debris and prevent the debris from clogging pipelines and filter screens.

In order to realize the purpose of the utility model, the following technical proposals are adopted: an orthopedic suction device includes a holding tube, a suction tube fixedly connected to the front end of the holding tube, an arc tube fixedly connected to the rear end of the holding tube, and a connecting tube The corrugated pipe joint at the other end of the arc-shaped pipe; a handle portion along the length direction of the grip pipe is integrally connected under the holding pipe; the central angle of the arc-shaped pipe is greater than 120 degrees, and the arc-shaped pipe is close to the bellows A funnel-shaped slag hopper is integrally connected below the position of the joint, and a slag storage bottle is detachably connected to the bottom of the slag hopper, and the arc-shaped tube is connected to a position corresponding to the slag hopper to guide the fluid into the slag hopper. Flow block, a filter screen is installed between the diversion block and the top of the slag hopper near the bellows joint side.

As a preferred solution: the holding pipe, the arc pipe and the slag hopper part are all composed of two symmetrical halves through ultrasonic welding.

As a preferred solution: the surface of the handle is formed with anti-slip embossed lines.

Compared with the prior art, the beneficial effect of the utility model is: by setting the arc tube, most of the liquid fluid will flow along the outer wall of the arc tube during the suction operation, coupled with the blocking of the diversion block, The bone debris will fall into the slag hopper, and the liquid will be sucked out through the filter screen and then through the bellows joint. The filter screen of the suction device with this structure is not easy to be blocked, and can continue to work for a long time.

Detailed ways

The specific embodiment of the utility model is described in detail below according to the accompanying drawings.

According to Fig. 1 and Fig. 2, a kind of orthopedic aspirator described in this embodiment includes a holding tube 2, a suction tube 1 fixedly connected to the front end of the holding tube, and an arc tube 4 fixedly connected to the rear end of the holding tube , and a bellows joint 6 connected to the other end of the arc tube; a handle portion 3 along the length of the tube is integrally connected below the holding tube; the central angle of the arc tube is 120-150 degrees , a funnel-shaped slag hopper 5 is integrally connected below the position of the arc-shaped tube close to the bellows joint, a slag storage bottle 7 is detachably connected under the slag hopper, and the arc-shaped tube is connected to a position corresponding to the slag hopper A diversion block 8 for guiding fluid into the slag hopper, and a filter screen 9 is installed between the diversion block and the upper side of the slag hopper near the bellows joint.

Each part of the suction device is made of plastic material, and the holding pipe, the arc pipe and the slag hopper part are all composed of two symmetrical halves through ultrasonic welding. The surface of the handle is formed with anti-slip embossed lines.

By setting the arc tube, most of the liquid fluid will flow along the outer wall of the arc tube during the suction operation, coupled with the blocking of the diversion block, the bone debris will fall into the slag hopper, and the liquid will be filtered The net is sucked out through the bellows joint. The filter net of the suction device of this structure is not easy to be blocked and can work continuously for a long time.

When in use, the bellows is connected through the bellows joint, and the other end of the bellows is connected to a negative pressure source to perform suction operation.
