technical field

The invention relates to the technical field of medical supplies, in particular to a sleeve-type nail pulling device.

Background technique

Blood stasis in the nails caused by heavy objects crushing the nails of the hands and feet in life, subungual empyema caused by paronychia, or eversion of the nails caused by strenuous exercise. For such finger injuries where the nails are partially detached from the nail bed, It is necessary to remove the damaged nails as soon as possible in order to perform anti-inflammatory, dredging, and anti-infection treatments on the damaged tissue. The traditional nail removal technique is to apply anesthesia to the affected area and remove the nails "violently" with nail clippers. This kind of nail removal method may take part of the tissue on the nail bed together, which brings great pain to the patient. The use of nail pulling forceps causes a great sense of fear to the patient visually. At the same time, the strength of the medical staff to pull the nail is difficult. Mastery, large, vigorous stretches will be excruciatingly painful for the patient's recovery period.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to Figures 1-4, the present invention provides a technical solution:

A sleeve-type nail pulling device comprises a casing 1, the casing 1 is used as a bearing device for each component, a finger clip 2 is fixedly installed on the casing 1, the finger clip 2 is used to fix the finger knuckles, and the finger clip 2 is mounted on the A tightening knob 3 is movably installed, and the finger knuckles are fixed by rotating the tightening knob 3. A tightening ring 4 is movably installed on the finger clip 2, and the rotation of the tightening knob 3 drives the tightening ring 4 to shrink, thereby fixing the finger knuckles On the device, a fixing block 5 is fixedly installed in the housing 1, a threaded hole 6 is opened on the fixing block 5, and a threaded rod 7 is movably sleeved in the threaded hole 6. The threaded rod 7 can move in the threaded hole 6, and the threaded rod 7 is fixedly connected with the nail pulling knob 8, and the threaded rod 7 is driven to rotate by rotating the nail pulling knob 8. One end of the threaded rod 7 away from the nail pulling knob 8 is provided with a ball groove 9, and a ball 10 is movably installed in the ball groove 9. The nail pulling block 11 is fixedly connected. When the threaded rod 7 rotates and shrinks, it drives the ball 10 to shrink backward, and the ball 10 shrinks backward to drive the nail pulling block 11 to move. The nail pulling block 11 is fixedly connected with the pulling stainless steel sheet 12. The movement drives the pulling stainless steel sheet 12 to move, and one end of the pulling stainless steel sheet 12 away from the nail pulling block 11 is fixedly connected with the nail fixing stainless steel sheet 13. Pulling the stainless steel sheet 12 to move drives the nail fixing stainless steel sheet 13 to move, and the shell 1 is also provided with an operation port 14 , apply universal glue to the nail through the operation port 14, so that the nail is fixedly connected with the nail fixing stainless steel sheet 13, and the pulling condition of the nail can be observed through the operation port 14.

As a preferred option, a rubber pad is fixedly installed on the inner side of the fastening ring 4 to prevent damage to the phalanx when the fastening ring 4 fixes the phalanx, so as to provide protection for the phalanx.

As a preferred option, a chute 15 is also opened in the threaded hole 6, a slider 16 is movably installed in the chute 15, the slider 16 can move in the chute 15, and the slider 16 is fixedly connected with the nail pulling block 11. The slider 16 is installed in the chute 15, so that the nail pulling block 11 does not rotate with it during the rotation of the threaded rod 6, thereby ensuring that the stainless steel sheet 12 will not be twisted, preventing the nail from being twisted and breaking, causing unbearable to the patient. Painful, when pulling the stainless steel sheet 12 to fix it on the side of the nail fixing stainless steel sheet 13 close to the fingertip, when the nail pulling block 11 is pulled back, pull the stainless steel sheet 12 and pull the fingertip of the nail fixing stainless steel sheet 13 to prevent the nail from lifting Turn over to ensure that the nail always moves in the growth direction during the pulling process, effectively reducing the pain of the patient when pulling the nail.

As a preferred option, a blocking block 17 is also fixedly installed on the housing 1, and the blocking block 17 is used to prevent the finger from sliding forward under the action of a huge pulling force when the nail pulling knob 8 rotates, so as to leave a gap between the nail and the fixing block 5. There is a certain amount of space to be drawn out to ensure the normal operation of the armour extraction.

Working principle: When the medical staff is pulling the nails, they inject anesthesia into the knuckles that need to be pulled out, and then insert the device into the patient's knuckles. After moving to the appropriate position, turn the tightening knob 3 and tighten the knob 3 Rotate and drive the tightening ring 4 to tighten, so that the knuckles of the fingers are firmly fixed to prevent the device from sliding during the nail pulling process, and then use super glue to coat the surface of the nail, and paste the nail fixing stainless steel sheet 13 on the surface of the nail. After the super glue is cured, turn the nail pulling knob 8, the nail pulling knob 8 rotates to drive the threaded rod 7 to rotate, the threaded rod 7 rotates to move backward in the threaded hole 6, the threaded hole 6 moves to drive the nail pulling block 11 to move, and the nail pulling block is moved. 11 Moves to drive the pull stainless steel sheet 12 to move, pull the stainless steel sheet 12 to move to drive the nail fixing stainless steel sheet 13 to move, and the nail fixation stainless steel sheet 13 moves to drive the nails to disengage. When in use, turn the nail pulling knob 8 a certain number of turns each time, and then again after a period of time. Rotate for a certain number of times, use a stable and long-lasting pulling force to gradually loosen the nail, and finally separate it from the nail bed. After pulling it out, loosen the tightening knob 3 and take off the device.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the invention is defined by the appended claims and their equivalents.
