Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in figures 1-4, a detachable bone curet comprises a spoon head 1, a spoon rod and a handle 2, wherein the spoon rod consists of a first spoon rod 3 and a second spoon rod 4, the spoon head 1 is arranged at one end of the first spoon rod 3, and one end of the first spoon rod 3, which is far away from the spoon head 1, is in threaded connection with the second spoon rod 4.

One end of the handle 2 is provided with a fixing rod 5, a plurality of splines 6 which are distributed along the circumferential direction at equal intervals are arranged on the fixing rod 5, and one end of the second key rod 4, which is far away from the first key rod 3, is provided with a key groove 7 for the sliding and embedding of the splines 6. The same locking hole 8 penetrates through one side of the fixing rod 5 and one side of the second key rod 4, and a locking part 9 used for fixing the handle 2 and the second key rod 4 mutually is arranged in the locking hole 8.

This application is through dividing into the bone curet three-section, realizes convenient dismantled and assembled. Meanwhile, the spoon rod is divided into a first spoon rod 3 and a second spoon rod 4, and the spoon head 1 is arranged at one end of the first spoon rod 3. If the spoon head 1 needs to be discarded after being used in the operation, the spoon head 1 and the first spoon rod 3 can be directly discarded and replaced by a new spoon head 1 and a new first spoon rod 3. The second spoon rod 4 can prolong the length of the bone curette, so that the situation that the hand of a doctor is too close to the surgical part of a patient to cause the surgical view of the doctor to be shielded by the hand of the doctor is avoided. In addition, the second spoon rod 4 and the handle 13 are detachably arranged. If the second spoon rod 4 contacts blood and tissue of a patient during operation, the second spoon rod 4 is discarded at the same time by detaching the handle 2 from the second spoon rod 4. Thereby ensuring reuse of the handle 2.

The method comprises the following specific operations: when the handle 2 and the second key rod 4 are detached, the locking part 9 is released, and then the handle 2 and the second key rod 4 are moved towards the direction away from each other until the fixing rod 5 is completely separated from the key groove 7, so that the detachment of the handle 2 and the second key rod is realized. Then, after the new second key rod 4 is taken out, the key groove 7 at one end of the new second key rod is aligned with the fixing rod 5. The splines 6 are fitted with the keyways 7. Finally, after the second key rod 4 is sleeved on the outer wall of the fixed rod 5, the locking part 9 is locked, and the installation and the replacement of the second key rod 4 can be realized.

Furthermore, the locking portion 9 comprises an elastic hook 10, a rod body 11, a pull rod 12 and a handle 13 which are connected in sequence, an external thread (not shown in the drawing) is arranged on the outer surface of the pull rod 12, and a baffle 14 for pressing the side wall of one side of the second spoon rod 4 is connected with the external thread of the pull rod 12 in a threaded manner.

Furthermore, the number of the elastic hooks 10 is two, and the two elastic hooks are symmetrically arranged along the axial lead of the rod body 11. A pair of elastic hooks 10 is used for hooking the other side wall of the second spoon rod 4.

Furthermore, a through hole 15 penetrates through the baffle plate 14, and the pull rod 12 is in threaded connection with the through hole 15.

After the elastic hook 10 is inserted into the locking hole 8, the driving rod 11 and the elastic hook 10 slide along the inner wall of the locking hole 8. Until the baffle 14 is abutted against the side wall of one side of the second key rod 4, the elastic hook 10 is separated from the locking hole 8 and springs open to hook the side wall of the other side of the second key rod 4.

Subsequently, the operator fixes the barrier 14 by hand so that the barrier 14 does not perform circumferential rotation. At this time, the operator rotates the handle 13 by hand to drive the pull rod 12 to rotate synchronously, so that the baffle 14 moves along the axial direction of the pull rod 12, and the distance between the baffle and the elastic hook 10 is reduced. Until the elastic hook 10 presses the side wall of the second key rod 4 and the baffle 14 abuts against the side wall of the other side of the second key rod 4, the locking of the locking part 9 can be realized. In addition, because the baffle 14 is connected with the pull rod 12 through threads, the threads have a backstop effect, and the baffle 14 can be prevented from being displaced without external force.

When the lock portion 9 is released, the operator presses the shutter 14 with the hand so that the shutter 14 does not perform circumferential rotation. Then, the operator rotates the handle 13 with the hand to drive the pull rod 12 to rotate synchronously, so that the baffle 14 moves along the axial direction of the pull rod 12, the distance between the baffle and the elastic hook 10 is enlarged, the elastic hook 10 is pressed into the locking hole 8 after the elastic hook 10 is separated from the side wall of the second key rod 4, and then the baffle 14 is pulled to drive the rod body 11 and the elastic hook 10 to move outwards. The release of the locking part 9 is realized until the rod body 11 and the elastic hook 10 are completely separated from the locking hole 8. The rod body 11 plays a role of fixing the elastic hook 10.

Furthermore, a connecting rod 16 is arranged at one end of the second spoon rod 4 facing the first spoon rod 3, an external thread is arranged on the outer side of the connecting rod 16, a holding groove (not shown in the drawing) matched with the connecting rod 16 is arranged at one end of the first spoon rod 3 facing the second spoon rod 4, and an internal thread matched with the external thread of the connecting rod 16 is arranged on the groove wall of the holding groove.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
