Abstract
The patent of the utility model relates to a medical instrument, in particular to a medullary cavity filing and pulling device with a handle provided with a guide groove and used in an artificial joint replacement operation. In the operation process, the bone hammer can slide upwards along a guide groove designed on a handle of the medullary cavity filing and extracting device, and the medullary cavity filing and extracting device is knocked reversely to extract the medullary cavity of the medullary cavity filing and extracting device.
Description
Technical Field
The patent of the utility model relates to a medical instrument, in particular to a medullary cavity filing and pulling device with a handle provided with a guide groove and used in an artificial joint replacement operation.
Background
In the artificial joint replacement operation, a medullary cavity file is needed to file a formed space position in a human femoral medullary cavity, when the medullary cavity file is pulled out, a traditional bone hammer is beaten without directional guide, the bone hammer is easily caused to fly out, and the operation risk is increased.
Disclosure of Invention
The utility model discloses to prior art's defect, provide a pulp cavity file of handle area guide way and play the ware, can guarantee accurate the striking for the hammer direction when reverse hammering pulp cavity file is played the ware.
In order to solve the technical problem, the technical scheme of the utility model as follows.
The handle 1 of the medullary cavity filing and extracting device is provided with an inward concave guide groove, the bone hammer 3 slides upwards along the guide groove, the handle 2 of the medullary cavity filing and extracting device is knocked reversely, and the medullary cavity filing and extracting device connected with the medullary cavity filing and extracting device can be extracted out of the medullary cavity.
Further, the guide slot interface may be circular, trapezoidal, square, or polygonal.
Furthermore, the handle 1 of the medullary cavity filing and extracting device can be provided with guide grooves on both sides, the bone hammer 3 can be matched with any side of the handle, and the guide grooves can be arranged on only one side of the handle.
Further, if the guide grooves are designed on both sides of the handle of the medullary cavity filing and extracting device, the guide grooves on both sides can be symmetrical or asymmetrical, the interface of the guide grooves on both sides can be arc-shaped, one side can be arc-shaped, and the other side is trapezoidal.
Further, the guide way that designs on the handle 1 provides the guide effect for the bone hammer 3, and in the operation process, the bone hammer 3 has only guaranteed that the bone hammer reciprocates in the guide way along the reverse percussion pulp cavity file of guide way and has pulled out the ware, and the bone hammer 3 is difficult to the departure like this, improves the operation accuracy.
Drawings
FIG. 1 is a cross-sectional view of a medullary cavity filing and extracting device with a handle provided with a guide groove and the guide groove of the handle.
FIG. 2 is a schematic view of the combination of a bone hammer and a medullary cavity filing and extracting device with a handle provided with a guide groove.
Detailed Description
The following describes the present invention with reference to the accompanying drawings and embodiments.
As shown in the attached figure 1 of the specification, a handle 1 of the medullary cavity filing and extracting device is provided with an inward concave guide groove, when a bone hammer 3 slides upwards along the guide groove and reversely strikes a handle 2 of the medullary cavity filing and extracting device, the medullary cavity filing and extracting device connected with the medullary cavity filing and extracting device can be extracted out of the medullary cavity.
The guide slot interface may be circular, trapezoidal, square or polygonal.
The handle 1 of the medullary cavity filing and extracting device can be provided with guide grooves on both sides, the bone hammer 3 can be matched with any side of the handle, and the guide groove can be arranged on only one side of the handle.
If the guide grooves are designed on both sides of the handle of the medullary cavity filing and extracting device, the guide grooves on both sides can be symmetrical or asymmetrical, the interface of the guide grooves on both sides can be arc-shaped, one side can be arc-shaped, and the other side can be trapezoid.
As shown in the attached figure 2 of the specification, the handle 1 of the medullary cavity filing and extracting device is provided with an inwards concave circular arc-shaped guide groove, the bone hammer 3 slides up and down along the circular arc-shaped guide groove, and the matching surface between the two is an arc-shaped interface 4. The guide groove provides a guide effect for the bone hammer 3, and ensures the directionality and the accuracy when the bone hammer 3 reversely strikes the medullary cavity filing and extracting device.
The guide way that designs on the handle 1 provides the guide effect for the bone hammer 3, and in the operation process, the bone hammer 3 has guaranteed that the bone hammer only reciprocates in the guide way along the reverse percussion medullary cavity file of guide way, and the bone hammer 3 is difficult to the departure like this, improves the operation accuracy.
The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is specific and detailed, but the invention can not be understood as the limitation of the patent scope of the present invention, but all the technical solutions obtained by adopting the equivalent substitution or equivalent transformation should fall within the protection scope of the present invention.
