Abstract

The utility model relates to an orthopedic dissociation body extracting device with an adsorption function, which comprises a plier body, a fixing plier handle, and a movable plier handle. The front end of the plier body is a flow adsorption guide pipe, and a position limiting guide annular table which is provided with a through hole is arranged in the flow adsorption guide pipe. A plier rod is penetrated with in a pipe cavity of the flow adsorption guide pipe by the position limiting guide annular table. An elastic plier clamp is installed on the front end of the plier rod, and the rear end of the plier rod passes through a supporting plate of the plier body to be contacted with the upper end of the movable plier handle. A return spring is sheathed on the plier rod, and a liquid through cavity and a liquid outlet pipe opening are arranged in the plier body. The orthopedic dissociation body extracting device with an adsorption function has the advantages of reasonable structure and convenient use. A dissociation body can be rapidity clamped and taken out by negative pressure adsorption, the time of an operation is shorten, the pain of a patient is reduced, and the operation is simple and quick.

Description

Orthopaedics episome extractor with adsorption function

This utility model relates to a kind of orthopedic operating apparatus, especially a kind of episome extractor of orthopaedics with adsorption function.

In bone surgery, sometimes need to clear up the episome in the joint part, generally be under arthroscope, episome to be taken out with common extractor (being operating forceps), still, owing to must make the joint full in the joint arthroscopic diagnosis, full agent is a water, therefore and the free property of episome in water is stronger, when common extractor during near episome, understands and cause moving about of episome because of extractor moves the vibrations that bring current, when making episome and shift out outside the Arthroscopic visual field, difficult quilt is clamped taking-up.Not only increased operating difficulty, prolonged operating time, also increased misery to the patient.

That the purpose of this utility model designs at existing problem in the present prior art just is a kind of rational in infrastructure, easy to use, can rapidly episome be clamped the special equipment of taking-up by vacuum suction.

The purpose of this utility model is finished by following scheme: the orthopaedics episome extractor that originally has adsorption function, it comprises caliper, be fixed in fixation clamps handle and the adjustable clamp handle that is hinged on the caliper on the caliper, the front end of caliper is for inhaling conduit, be provided with the spacing guide ring platform that is processed with through hole on it in the conduit, claw beam is installed on by spacing guide ring platform to be inhaled in the conduit tube chamber, the claw beam front end is equipped with the elasticity clamp, the claw beam rear end is passed the caliper support plate and is contacted with the upper end of adjustable clamp handle, process limiting stand on the claw beam, on the claw beam between spacing guide ring platform and the limiting stand, be set with return spring, be processed with the fluid-through chamber and the fluid mouth of pipe in the caliper, fluid-through chamber is communicated with the tube chamber of inhaling conduit.

The fluid mouth of pipe described in this utility model is located at the rear end of caliper.

This utility model is owing to be provided with suction stream pipe, therefore has the vacuum suction effect, when this extractor enters joint part under arthroscope cooperates, can make it be adsorbed on extractor clamp place by the vacuum suction episome, finger presses adjustable clamp handle, drive claw beam forward, the elasticity clamp promptly opens, when treating that episome is positioned at elasticity clamp jaw place, unclamp the adjustable clamp handle, claw beam is rapid return under the return spring effect, and meanwhile clamp is tightly clamped episome, the elasticity clamp that accompanies episome promptly is retracted into to be inhaled in the stream pipe, and episome is just taken out smoothly.The advantage of this extractor is: rational in infrastructure, easy to use, can rapidly episome be clamped taking-up by vacuum suction, and shortened operating time, also reduced patient's misery, make operation simple, quick, the renewal product of a kind of existing apparatus of can yet be regarded as.

Accompanying drawing is a structural front view of the present utility model.

This utility model is described further below in conjunction with accompanying drawing:

As shown in the figure: the orthopaedics episome extractor that originally has adsorption function, it comprises caliper (1), be fixed in the fixation clamps handle (2) on the caliper and be hinged on adjustable clamp handle (3) on the caliper, fixation clamps handle (2) is an integral structure with caliper (1), the front end of caliper (1) is for inhaling conduit (4), inhale in the conduit and be provided with the spacing guide ring platform (5) that is processed with through hole (6) on it, claw beam (7) is installed on by spacing guide ring platform (5) to be inhaled in conduit (4) tube chamber, claw beam (7) front end is equipped with elasticity clamp (8), claw beam (7) rear end is passed caliper support plate (10) and is contacted with the upper end of adjustable clamp handle (3), claw beam (7) is gone up processing limiting stand (11), on the claw beam (7) that is positioned between spacing guide ring platform (5) and the limiting stand (11), be set with return spring (12), be processed with the fluid-through chamber (13) and the fluid mouth of pipe (9) in the caliper (1), the fluid mouth of pipe (9) is located at the rear end of caliper (1), and fluid-through chamber (13) is communicated with the tube chamber of inhaling conduit (4).
