Description

The chest and shoulder bridge like supporting combined laryngoscope

This utility model relates to a kind of medical apparatus and instruments, a kind of more specifically medical treatment device of checking and treating the bottleneck throat pathological changes.

Supporting laryngoscope and self-retaining laryngoscope are arranged in the existing laryngoscope.Supporting laryngoscope is by the direct laryngoscope pipe, and support bar and breast backing plate are formed.In use exist following defective: the breast backing plate directly is pressed in patient's chest when 1, executing art, can bring discomfort to the patient; 2, be subjected to the restriction of laryngoscope pipe, the little operation inconvenience in the visual field; 3, braking element adopts ratchet spanner, spiral or worm gear rod-type, in case need to end to perform the operation when removing laryngoscope, dismounting speed is slow; 4, handle and laryngoscope pipe are fixed as one, and function of use is single, can not use by a mirror more.Self-retaining laryngoscope is made up of suspension, spatula and gag, and the deficiency of existence is 1, suspension is braked complex structure cost height by Double helix; 2, function singleness, operation inconvenience.

The purpose of this utility model just is to overcome above-mentioned deficiency, and it is the chest and shoulder bridge like supporting combined laryngoscope of one that a kind of support, suspention and opening three function of collecting is provided.

Compare with original two kinds of laryngoscopes, owing to changed supporting construction and brake structure; Therefore the connected mode of laryngoscope pipe, spatula and handle in use not only makes doctor's more convenient operation, has also reduced painful and uncomfortable to the patient.

The purpose of this utility model is achieved in that

A kind of chest and shoulder bridge like supporting combined laryngoscope, spatula (1) by different size, laryngoscope pipe (13) (15), gag (3), handle (4), ratchet actuator (5), support bar (6), regulate connecting rod (7), crossbeam (8), balance plate (9), support compositions such as (10), the rear end that it is characterized in that support bar pass balance plate ride over two groups can the crossbeam of reduced herringbone on, the front end of support bar links to each other with handle by the L bar of the company's of adjusting end, on support bar and handle, be respectively equipped with the ratchet actuator, straight-bar one end of adjusting connecting rod links to each other with the ratchet actuator on the support bar, the other end is hooked in the otic placode on the handle, the lower end that spatula or laryngoscope pipe vertically insert handle, by the ratchet controller lock on the handle, gag is then in the base frame of laterally inserted handle, at its lower end, by bolting.

Have keyway on the upright handle of spatula and laryngoscope pipe.

Gag is a U-shaped bar, and an end of bar is provided with front tooth card (2).

The laryngoscope pipe is provided with semi-canal type laryngoscope pipe (13) and side formula laryngoscope pipe (15), and has beam duct (14) on tube wall.

The utility model is described in further detail below in conjunction with accompanying drawing

But change the breast backing plate in the existing supporting laryngoscope into two groups of convertible herringbones, place on patient's the breast shoulder, just as a bridge formation beam, the whole device that is used for supporting laryngoscope, make it not contact, so neither influence patient's breathing, be convenient to general anesthesia patient's monitoring again with patient's breast shoulder.After operation finishes,, amount to support and can draw in and deposit as long as extract support bar out balance plate.

Regulate connecting rod and be made up of a straight-bar and a L shaped bar, an end of straight-bar links to each other with ratchet actuator on the support bar, and by dowel fixes, the other end is hooked in the otic placode on the handle.One end of L shaped bar and straight-bar are by dowel fixes, and the other end is cut respectively in handle and the support bar by dowel fixes.Drive the high and low angle that the adjusting connecting rod can be controlled spatula or laryngoscope effectively by the ratchet actuator, reach the required purpose that gets a clear view.

Offer keyway on the upright handle of spatula and laryngoscope pipe, not only make the ratchet actuator on the handle carry out the adjustment of height to spatula and laryngoscope pipe, firm locking is dismantled easily, and can prevent the rotation of spatula and laryngoscope pipe level.

In a single day need during operation to end operation,, can promptly the laryngoscope pipe be removed as long as press the stop spanner on the ratchet actuator.Since easy to loading and unloading quick, therefore can be when operation according to different different spatula and the laryngoscope pipes of needs configuration.Because gag is in the base frame of laterally inserted handle, at its lower end, by bolting, dismounting is also convenient, and can not influence the use of spatula and laryngoscope pipe in use, the utlity model has the many usefulness of a mirror, evident characteristic easy to use thereby make again.
