Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution:
a sleeve type nail pulling device comprises a shell 1, the shell 1 is used as a bearing device of each part, a finger clamp 2 is fixedly arranged on the shell 1, the finger clamp 2 is used for fixing a finger knuckle, a fastening knob 3 is movably arranged on the finger clamp 2, the finger knuckle is fixed by rotating the fastening knob 3, a fastening ring 4 is movably arranged on the finger clamp 2, the fastening knob 3 rotates to drive the fastening ring 4 to contract, so that the finger knuckle is fixed on the device, a fixing block 5 is fixedly arranged in the shell 1, a threaded hole 6 is formed in the fixing block 5, a threaded rod 7 is movably sleeved in the threaded hole 6, the threaded rod 7 can move in the threaded hole 6, the threaded rod 7 is fixedly connected with a nail pulling knob 8, the threaded rod 7 is driven to rotate by rotating the nail pulling knob 8, a ball groove 9 is formed in one end, far away from the nail pulling knob 8, of the threaded rod 7, and a ball, ball 10 and the first piece 11 fixed connection that pulls out, when the rotatory shrink of threaded rod 7, drive ball 10 and shrink backward, ball 10 contracts backward and drives and pull out first piece 11 and remove, pull out first piece 11 and the stainless steel 12 fixed connection of pulling, it drives the stainless steel 12 of pulling to pull first piece 11 and remove to pull first piece 11, the stainless steel 12 of pulling is kept away from and is pulled out first piece 11 one end and the fixed stainless steel 13 fixed connection of nail, the fixed stainless steel 13 of nail is moved to the fixed stainless steel 13 of pulling, operation mouth 14 has still been seted up on casing 1, scribble universal glue through operation mouth 14 to the nail, make nail and the fixed stainless steel 13 fixed connection of nail, and can observe the condition of pulling of nail through operation mouth 14.
Preferably, a rubber pad is fixedly arranged on the inner side of the fastening ring 4, so that the finger joint is prevented from being damaged when the fastening ring 4 fixes the finger joint, and the finger joint is protected.
Preferably, a sliding groove 15 is further formed in the threaded hole 6, a sliding block 16 is movably mounted in the sliding groove 15, the sliding block 16 can move in the sliding groove 15, the sliding block 16 is fixedly connected with the nail pulling block 11, the sliding block 16 is mounted in the sliding groove 15, so that the nail pulling block 11 does not rotate along with the threaded rod 6 in the rotating process, the situation that the pulled stainless steel sheet 12 cannot twist is guaranteed, the nail is prevented from twisting off, and pain which is difficult to bear is caused to a patient is avoided.
Preferably, the housing 1 is further fixedly provided with a stop block 17, and when the stop block 17 is used for stopping the nail pulling knob 8 from rotating, the finger slides forwards under the action of huge pulling force, so that a certain pulling space is reserved between the nail and the fixed block 5, and the normal nail pulling operation is ensured.
The working principle is as follows: when a medical worker pulls nails, anesthetic is injected to the knuckle needing to be pulled, the device is sleeved into the knuckle of a patient and moved to a proper position, the fastening knob 3 is rotated to drive the fastening ring 4 to be tightened, so that the knuckle of the finger is firmly fixed, the device is prevented from sliding in the nail pulling process, then strong glue is used for coating the surface of the nail, the nail fixing stainless steel sheet 13 is pasted on the surface of the nail, after the strong glue is cured, the nail pulling knob 8 is rotated to drive the threaded rod 7 to rotate, the threaded rod 7 is rotated to enable the threaded rod to move backwards in the threaded hole 6, the threaded hole 6 moves to drive the nail pulling block 11 to move, the nail pulling block 11 moves to drive the pulling stainless steel sheet 12 to move, the nail fixing stainless steel sheet 13 is driven to move, and the nail fixing stainless steel sheet 13 moves to drive the nail to separate, when in use, the nail pulling knob 8 is rotated for a certain number of turns every time, and is rotated for a certain number of turns again after a certain time interval, the nail is gradually loosened by utilizing stable and lasting pulling force and finally separated from the nail bed, the fastening knob 3 is loosened after the nail is pulled out, and the device is taken down.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
