Description

Anesthesia position fixation bracket in spinal canal

technical field

The utility model relates to the field of medical instruments, in particular to a bracket for fixing the anesthesia position in the spinal canal.

Background technique

The success of neuraxial anesthesia depends largely on the patient's cooperation and the patient's position, and a comfortable position can often improve patient compliance. There are two puncture positions for spinal anesthesia: lateral position and sitting position. Due to the lack of special spinal anesthesia puncture fixation brackets at home and abroad, the application rate of sitting position puncture method is lower than that of lateral position. It is only used in obese patients or The sitting position puncture method is only used when the lateral position puncture fails. Since there is no special seat puncture fixing bracket, ordinary chairs can only be used instead. The patient must move from the operating table to the chair, and then move back to the operating table after the puncture is successful on the chair, which increases the risk of accidents for the patient during the moving process. .

There are many unsafe factors in the replacement of fixed puncture brackets by moving chairs: first, the puncture operation of spinal anesthesia requires the patient to be absolutely still, and any movement will increase the risk of damage to blood vessels and nerves, resulting in serious anesthesia complications, while A moving chair can't do that. Second, during the sitting puncture process, the patient needs to ride on the chair facing the back of the chair. The curvature of the back of the chair cannot completely open the intervertebral space of the patient, which increases the difficulty of puncture, especially for pregnant women. making this action more difficult. Third, this posture facing the back of the chair and straddling the chair is very uncomfortable, and the patient cannot maintain this posture for a long time, which reduces the patient's compliance and increases the non-subjective non-cooperation of the patient.

Utility model content

Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a freely adjustable spinal canal internal stagnation anesthesia position fixation bracket.

Technical solution: The utility model provides an anesthesia position fixation bracket in the spinal canal, which includes a support body whose free end can be adjusted up and down and front and rear, a clamping body, and a curved rod connecting the support body and the clamping body. The bracket is fixed on the side rail of the operating bed, fixed by the clamping body, and the curved rod makes the support body forward for a certain distance. When the patient puts the mandible on the support body, the body is arched, and the intervertebral space of the patient is opened the most. Conducive to the puncture operation of spinal anesthesia.

Further, the support body includes a sliding combined base and a horizontally moving slider, the upper surface of the slider is connected to an upright first support rod, and the free end of the first support rod is provided with a jaw rest. The base is provided with rail grooves, and the rail grooves are provided with a plurality of slider pin holes along the sliding direction of the slider. The slider is opened from the upper surface and is installed with a latch inserted into the slider pin holes. A waist-shaped hole is provided on the side of the base, and a handle bar is installed horizontally on both sides of the slider protruding from the waist-shaped hole.

The lower part of the base is a cylindrical part with side holes on the side, and a lifting rod fixed to the upper end of the curved rod is arranged in the cylindrical part. The lifting rod is provided with several height-adjusting pin holes distributed at different heights. It is connected with the side hole of the cylindrical part through the height adjustment pin. Adjust the height between the cylindrical part and the lifting rod, and insert the height adjustment pin when the height adjustment pin hole corresponds to the side hole to realize height adjustment and fixation.

The clamping body includes a deck and a clip hinged to each other, the deck is connected to the lower end of the curved rod, the deck is provided with an upper latch that clamps the side rail of the operating bed from the upper end, and one end of the hinged part of the clip is provided with a clip that clamps the operating bed. The lower locking tooth at the lower end of the side rail is extended to form a pressing handle at the other end. The shape of the pressure handle can be adjusted according to actual conditions. When the clamping body is also equipped with a pedal device, when the pressure handle and the lower latch are arranged in the middle of the card seat, it will affect the use. A slot is opened in the middle to allow the second support rod of the pedal device to pass through, which can ensure It will not be hindered when using the press handle.

As a preferred solution of the present utility model, a height-adjustable pedal device is installed at the lower end of the clamping body. The pedal device includes a second support rod installed on the lower end of the clamping body, and a first pedal and a second pedal horizontally installed on both sides of the second support rod; the two sides of the second support rod are respectively There is a row of sockets for fixing the first footrest and the second footrest for height adjustment.

The first pedal and the second pedal are respectively provided with a pair of horizontal bars connected horizontally to the socket and connected to each other, and a pedal installed on the horizontal bar.

The upper surface of the jaw support of the utility model forms a concave arc surface in the middle, and the surface of the jaw support is provided with a silica gel pad.

Generally speaking, the angle between the line connecting the clamping body and the jaw rest and the vertical line where the jaw rest is located is 10° to 35°. It is most comfortable for the patient to maintain an arched position at this angle. In this arched position, the patient can reach the maximum Widen the intervertebral space to a certain extent.

Beneficial effects: the utility model realizes the up and down, front and back movement of the jaw support, the up and down movement of the pedal device, and the effective fixation on the side rail of the operating bed. By setting a curved rod with a certain radian, when the patient puts the mandible into the jaw rest, the back is arched to facilitate the anesthesiologist to perform the puncture operation of spinal canal anesthesia, thereby improving the puncture success rate of spinal canal anesthesia, especially suitable for Obese patients and patients with difficulty in neuraxial anesthesia puncture.
