Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an angle-adjustable osteotome for an intervertebral foramen mirror operation.
Background
The traditional bone chisel under the mirror is generally formed by integrating a bone chisel body and a bone chisel head, and the tail end of the bone chisel body is processed into the bone chisel head. When intervertebral foramen mirror minimally invasive surgery is carried out, the osteotome enters a lesion part from the endoscope pore passage to chisel scleroderma variants, the endoscope pore passage is a straight hole, the osteotome can only be made into a straight rod shape, and focus in a limited range is processed, but in the actual surgery process, the visual field of the endoscope is far larger than the working range of the osteotome, so that the straight rod osteotome has a large surgery blind area, and focus of the blind area cannot be cut. In order to increase the working range of the osteotome, the bone channel outside the endoscope needs to be enlarged for the second time, then the endoscope is moved to the affected body part, and the hard focus is cut, but enlarging the bone channel prolongs the operation time, increases the operation difficulty, increases the operation risk, and excessively enlarging the bone channel may affect the stability of the spine.
The utility model discloses a utility model patent with publication number CN 208769901U discloses an under-mirror osteotome, the cross-section of the chisel head is in a semi-circular arc shape, the chisel head is bent to one side of the arc top of the semi-circular arc shape, the bony tissues with protruded surfaces can be rapidly and effectively chiseled, the operation time is short, the safety coefficient is high, and the pain of patients is small; but it is the same with traditional osteotome, has only changed the first blade form of osteotome, and is restricted by the endoscope pore, has great operation blind area, has increased the risk of patient's postoperative relapse.
The patent with publication number CN 103961155B discloses a split type bone chisel under mirror, includes handle, straight-bar and tool bit, the handle sets up in the one end of straight-bar, and the tool bit adopts detachable construction to be fixed in the other end of straight-bar. This grant patent has solved current osteotome and can not carry out energetically cutting operation and can't accomplish the osteophyte and the problem of calcification variant of handling the nerve root head end, but changes the osteotome tool bit repeatedly and can prolong operation time, and long-time operation can make the doctor produce tired sense, all can cause certain psychological pressure to doctor and patient. After different osteotome heads are replaced, the excision of all osteophytes and calcification variants in a lesion area cannot be finished due to the limitation of endoscope channels, a large operation blind area exists, and the risk of postoperative recurrence of a patient is increased.
