As shown in fig. 1 to 5, the identification device for an instrument bar 200 of the present embodiment includes: the identification member 100, the identification member 100 is a ring structure, the identification member 100 is provided with an opening 110, the opening 110 extends to two axial ends of the identification member 100, and the inner side surface of the identification member 100 is provided with a positioning part 120; a plurality of limiting parts 210 corresponding to the positioning part 120 are sequentially arranged on the outer side surface of the instrument rod 200 along the axial direction of the instrument rod 200, and the positioning part 120 can be connected with any one of the limiting parts 210; when the marker 100 is sleeved on the instrument rod 200, the marker 100 and the instrument rod 200 are in tight fit.
According to the identification device for the instrument rod 200, the identification piece 100 is made of an elastic material, so that the opening part 110 of the identification piece 100 is enlarged, the positioning part 120 of the identification piece 100 is detached from the limiting part 210 of the connected instrument rod 200, and the identification piece 100 can freely move relative to the axial direction of the instrument rod 200, so that the positioning part 120 of the identification piece 100 can be connected with any one limiting part 210; when minimally invasive surgery is performed on an intervertebral space, a channel tube is inserted into the intervertebral space, then the instrument rod 200 is inserted into the channel tube, when a worker determines the position of the instrument rod 200 through an imaging device, the worker moves the identification piece 100 to the position abutting against the outer end of the channel tube, then the positioning part 120 of the identification piece 100 is connected with the corresponding limiting part 210, the position of the channel tube is fixed, the position of the identification piece 100 abutting against the channel tube is positioned, and the position of the instrument rod 200 connected with the identification piece 100 is also positioned; since the instrument rod 200 is a tool for intervertebral space surgical treatment, the marker 100 is positioned at the outer end of the channel tube after freely moving along the instrument rod 200, which can realize accurate positioning; when the identification piece 100 is sleeved on the instrument rod 200, the identification piece 100 is tightly matched with the instrument rod 200, so that the identification piece 100 is not easy to fall off after the positioning part 120 is connected with any one limiting part 210; the marking device for the instrument bar 200 of the present invention is simple to operate, shortens the operation time, and is convenient to clean and sterilize. The outer side surface of the instrument rod 200 is sequentially provided with a plurality of limiting parts 210 corresponding to the positioning parts 120, so that the positioning parts 120 can be conveniently connected with the limiting parts 210 at different positions, and accurate positioning can be realized. Because the marker 100 is sleeved on the instrument rod 200, the worker can clearly see the position of the marker 100 and can clearly see the position.
The positioning portion 120 and the limiting portion 210 are connected by plugging. The plug-in connection structure is simple and convenient to install and disassemble.
The positioning portion 120 is a bump; the limiting portion 210 is a groove disposed on the outer side surface of the instrument bar 200. The projection can be easily inserted into or removed from the recess, which makes the construction of the identification device more compact.
Each groove is disposed circumferentially along the outer side of the instrument stem 200. This configuration allows the tabs to be inserted into the recesses from various angles on the outside of the instrument bar 200 for ease of installation.
The opening 110 and the positioning portion 120 are disposed to face each other. After the worker enlarges the opening 110 of the marker 100, the geometric center of the marker 100 moves to the side where the opening 110 is located, and after the projection on the opposite side of the opening 110 leaves the outer diameter range of the instrument rod 200, the marker 100 can freely move to the position of the required marker along the axial direction of the instrument rod 200, and the structure is convenient for disassembling the marker 100 and the instrument rod 200.
The opposite edges 140 of the label 100, which form the opening 110, are respectively provided with outwardly protruding flange portions 130, and the flange portions 130 are drop-shaped. The drop-shaped structure prevents the worker from being hurt when the worker presses the flange part 130 with his hand to enlarge the opening part 110; on the other hand, this structure provides the flange portion 130 with a radial length that facilitates the pressing of the projection into the groove.
The inner diameter of the identifier 100 is equal to or less than the outer diameter of the instrument shaft 200. With the structure, when the projection is positioned outside the groove, the marker 100 can automatically hold the instrument rod 200 tightly without falling off.
The identification device for the instrument rod 200 further comprises a pressure ring device 300, wherein two handles 310 arranged oppositely to each other are arranged on the pressure ring device 300; the two ends of each handle 310 in the length direction are respectively a clamping end and a mounting end, the clamping ends of the two handles 310 are elastically connected, a clamping surface 311 is arranged on the clamping end of each handle 310, the clamping surfaces 311 of the two handles 310 are oppositely arranged, and a concave part 312 is arranged on the clamping surface 311 of each handle 310. The recess 312 of the pressure ring 300 can clamp the identifier 100 so that the identifier 100 can be stably placed in the pressure ring 300, facilitating control of the identifier 100.
The clamping surface 311 of each handle 310 is provided with two concave parts 312 which are sequentially arranged along the width direction of the clamping surface 311 of each handle 310, the width between the two concave parts 312 on the clamping surface 311 of each handle 310 is smaller than the axial length of the identification piece 100, and a notch 313 is arranged between the two concave parts 312 on the clamping surface 311 of each handle 310. This configuration facilitates stable gripping of the tag 100 by the handle 310.
The elastic material is a metal material having elasticity so as to provide the strength and elasticity to the marker 100. In this embodiment, the elastic material is a titanium alloy. The titanium alloy has elasticity and is convenient to be oxidized into various colors, so that the identification is facilitated.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention.
