Abstract
The invention discloses a nail taking device for orthopedics department, and relates to the field of medical instruments. The nail taking device for orthopedics department can be fixed on an operating table, and after screws are sleeved, a doctor rotates a handle to drive the screws to screw out of bones, so that the nail taking device is labor-saving and convenient to operate, and the operation efficiency is improved.
Description
Technical Field
The invention relates to the field of medical instruments, in particular to a nail taking device for orthopedics.
Background
In orthopedic surgery, it is often necessary to back out screws driven into bone, and the back out of these fixation screws requires the aid of a nail removal device. The existing nail taking device for orthopaedics is designed in a more traditional way and only has a clamp-shaped structure, and a doctor needs to rotate to take out a screw after clamping the head of the screw by using the device. The structure is labor-consuming to operate, and the consistency of rotation is poor, so that the efficiency of extracting the screw in the bone is too low, and the operation is affected.
Disclosure of Invention
The invention aims to solve the technical problem of providing a nail taking device for orthopedics department, which can be fixed on an operating table, and after a screw is sleeved, a doctor rotates a handle to drive the screw to be screwed out of a bone, so that the operation is very labor-saving and convenient, and the operation efficiency is improved.
In order to achieve the above purpose, the present invention provides the following technical solutions:
this a get nail device for orthopedics includes the screwed pipe of pipe shape, screwed pipe outer wall bilateral symmetry is equipped with the shaft-like support frame of two L shapes that the size is the same perpendicularly, two support frame tip all are equipped with flat-plate-shaped base perpendicularly, the screwed pipe is furnished with the threaded rod of mutual screw-thread fit, the length of threaded rod is greater than the length of screwed pipe, base one end is kept away from to the threaded rod is equipped with straight shaft-like handle perpendicularly, the threaded rod other end is equipped with the plate nail pulling sleeve that the cross-section is "[" shape perpendicularly, the inside slope of nail pulling sleeve is equipped with a plurality of diagonal braces, nail pulling sleeve is kept away from threaded rod one end center department and is opened the staple groove.
Preferably, the threaded pipe and the support frame are both made of stainless steel and are connected through welding.
Preferably, the base is made of stainless steel and is connected with the supporting frame through welding.
Preferably, the threaded rod and the handle are both made of stainless steel, and the threaded rod and the handle are connected through welding.
Preferably, the nail pulling sleeve and the diagonal brace are both made of stainless steel, and the nail pulling sleeve is connected with the threaded rod and the diagonal brace through welding.
The beneficial effect of adopting above technical scheme is: when the nail taking device for orthopedics is used, the two bases can be placed on an operating table, and the support frame is erected on the operation position of a patient. The head of the screw in the bone of the patient is sleeved into the screw clamping groove of the screw pulling sleeve, and then a doctor holds the handle to rotate the threaded rod in the threaded tube to drive the screw pulling sleeve to rotate so as to pull out the screw from the bone. The nail taking device for orthopedics department can be fixed on an operating table, and after screws are sleeved, a doctor rotates a handle to drive the screws to screw out of bones, so that the nail taking device is labor-saving and convenient to operate, and the operation efficiency is improved.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
FIG. 1 is a front view of the nail-removing device for orthopedics department of the invention;
fig. 2 is a left side view of the nail-removing device for orthopedics department of the invention.
Wherein, 1-nail pulling sleeve, 2-support frame, 3-threaded rod, 4-threaded pipe, 5-diagonal brace, 6-handle, 7-base, 8-nail clamping groove.
Detailed Description
The following describes in detail a preferred embodiment of the present invention for an orthopedic nail-removing device with reference to the accompanying drawings.
Fig. 1 and 2 show a concrete embodiment of the nail-removing device for orthopedics department, which comprises the following components:
with reference to fig. 1 and 2, the orthopedic nail taking device comprises a tubular threaded pipe 4, two L-shaped rod-shaped support frames 2 with the same size are symmetrically and vertically arranged on two sides of the outer wall of the threaded pipe 4, flat-plate-shaped bases 7 are vertically arranged on the end portions of the two support frames 2, threaded rods 3 in threaded fit with each other are arranged in the threaded pipe 4, the length of each threaded rod 3 is larger than that of the threaded pipe 4, a straight rod-shaped handle 6 is vertically arranged at one end, away from the base 7, of each threaded rod 3, a plate-shaped nail pulling sleeve 1 with a transverse cross section in a [ "shape is vertically arranged at the other end of each threaded rod 3, a plurality of inclined support rods 5 are obliquely arranged inside each nail pulling sleeve 1, a rectangular nail clamping groove 8 is formed in the center of one end, away from the.
Screwed pipe 4 and support frame 2 are made by stainless steel, and sturdy and durable, and corrosion resisting property is good, and screwed pipe 4 and support frame 2 are all through welded connection. Base 7 is made by the stainless steel, and is sturdy and durable, and corrosion resisting property is good, and base 7 all is connected with support frame 2 through the welding. Threaded rod 3 and handle 6 are made by stainless steel, and sturdy and durable, and corrosion resisting property is good, and threaded rod 3 and handle 6 pass through welded connection. Nail pulling sleeve 1 and diagonal brace 5 are made by the stainless steel, and are sturdy and durable, and corrosion resisting property is good, pulls out nail sleeve 1 and is connected with threaded rod 3 and diagonal brace 5 through the welding, and diagonal brace 5 can improve the steadiness of pulling out nail sleeve 1, prevents to pull out nail sleeve 1 atress deformation.
When the nail taking device for orthopedics is used, the two bases 7 can be placed on an operating table, and the support frame 2 is erected on the operation position of a patient. The head of the screw in the bone of the patient is sleeved into the staple slot 8 of the screw pulling sleeve 1, then a doctor holds the handle 6 by hand to rotate the threaded rod 3 in the threaded tube 4, and drives the screw pulling sleeve 1 to rotate so as to pull out the screw from the bone. The nail taking device for orthopedics department can be fixed on an operating table, and after screws are sleeved, a doctor rotates a handle to drive the screws to screw out of bones, so that the nail taking device is labor-saving and convenient to operate, and the operation efficiency is improved.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
