Problems solved by technology

[0012] The known methods and devices have the disadvantage that the required measures or features complicate the devices used and make them more expensive
Another disadvantage is that these known devices also require very precise positioning relative to the bone cement to be removed in order to avoid undesired damage to the bone itself

Embodiment Construction

[0037] The same reference numerals are used throughout the drawings to refer to the same parts whenever possible.

[0038] In the following description of the invention, the use of the instrument will be discussed with reference to the removal of bone cement from bone. However, the inventor expressly states that the use of the device of the invention is not limited to this application.

[0039] First refer to figure 1 , shows a surgical instrument 1 without a handle for removing cured bone adhesive according to the invention. The handle can be fixedly or removably attached to the instrument 1, the latter option being the preferred case. The instrument 1 may be used, for example, in hip orthopedic surgery and comprises a support rod or bar 2 and a crushing tool 3 for removing bone cement, which is arranged at the end 4 of the support rod or bar 2 place. In order to provide sufficient operating space for the apparatus, the support bar or support bar 2 preferably has a reduce...

Abstract

A surgical instrument (1) for use on a patient's bone, comprising a support rod or strip (2), and a crushing tool (3) arranged at an end (4) of the support rod or support strip (2), the The breaking tool (3) comprises a protrusion (5) and a knife or chisel (6), wherein a space (7) is provided between the protrusion (5) and the knife and chisel (6), the space (7) being arranged as for receiving material to be removed from the bone, wherein the knife or chisel (6) has at least two surfaces (8) facing the protrusion (5) intersecting at a joint intersection (9), This engaging intersection line (9) divides the knife or chisel (6) substantially into two parts on opposite sides of the intersection line (9), thereby providing separate operability to the knife or chisel (6).

Description

technical field [0001] The present invention relates to a surgical instrument for use on a patient's bone, comprising a support rod or strip, and a crushing tool arranged at the end of the support rod or support strip. [0002] Such surgical instruments have various applications, for example for removing bone that must be removed from other bones, or for removing cured bone cement such as used in orthopedic surgery. The surgical device of the present invention will be discussed below with reference to the removal of cured bone adhesive, but it should be understood that the use of the surgical device of the present invention is not limited thereto. Background technique [0003] WO94 / 22380 discloses a disposable surgical instrument for removing uncured bone adhesive. The instrument known from WO 94 / 22380 is used immediately after cementing the bone into which the implant is inserted - for example when placing a new hip joint. A portion of the implant will be securely fixed t...
