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.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-4, an orthopedic surgery is with getting needle device, including external sleeve 1, sliding connection has built-in sleeve 2 on the inner wall of external sleeve 1, threaded connection has annular fixed plate 3 on the outer wall of built-in sleeve 2, the inside of annular fixed plate 3 is provided with annular groove 5, sliding connection has backup pad 6 on the outer wall of built-in sleeve 2, and backup pad 6 is located the below of annular fixed plate 3, be provided with a plurality of T type lugs 4 of even size on the outer wall of backup pad 6 top portion, and the size of T type lug 4 equals with annular groove 5, slide rail 9 has been seted up in the inner wall of built-in sleeve 2 both sides, fixed mounting has slider 10 on the outer wall of backup pad 6 near built-in sleeve 2 both sides, and slider 10 is located the inside of slide rail 9.

The outer walls of the two sides of the bottom end part of the built-in sleeve 2 are movably connected with a clamping device 8 through a movable shaft. The outer wall of the support plate 6 far away from one side of the T-shaped lug 4 is movably connected with movable plates 7 through movable shafts. The outer walls of the movable plates 7 at the side far away from the supporting plate 6 are movably connected to the outer walls of the clamping devices 8.

A threaded rod 11 is fixedly installed in the inner wall of the top end part of the internal sleeve 2, and the threaded rod 11 penetrates through the inner top part of the external sleeve 1. The top end of the threaded rod 11 is fixedly provided with a rotating handle 12, and the outer wall of the rotating handle 12 is sleeved with an anti-skid rubber sleeve in a sliding manner.

The holding device 8 can hold the metal bone needle fixedly.

In the utility model, when medical staff uses the device to extract the metal spicules in the body of a patient, the clamping device 8 is firstly adjusted according to the metal spicules with different diameters, sizes and specifications in different bodies of different patients, so as to clamp the metal spicules with different models more stably.

Firstly, according to the specific practical situation, the annular fixing plate 3 is rotated upwards or downwards, when the annular fixing plate 3 is rotated, the annular groove 5 therein and the T-shaped projection 4 on the supporting plate 6 are matched with each other, so that the supporting plate 6 can drive the clamping device 8 to be unfolded and closed through the movable plate 7. Since the sliding blocks 10 in the supporting plate 6 can be slidably connected in the sliding rails 9 on the inner sleeve 2, when the supporting plate 6 is lifted up from the inner sleeve 2 by the annular fixing plate 3, the supporting plate 6 spreads the holding device 8 towards both sides by the movable plate 7. When the support plate 6 is moved downward from the inner sleeve 2 by the annular fixing plate 3, the support plate 6 closes the holding device 8 to both sides by the movable plate 7. So as to achieve the effect of more stably clamping the metal spicules of different models.

Finally, the threaded rod 11 on the built-in sleeve 2 is rotated through the rotating handle 12, and then the metal spicules in the body of the patient can be slowly extracted through the clamping device 8.
