Abstract
The utility model relates to a visual ring saw for operations. The visual ring saw is mainly suitable for spinal operations of the human body. The visual ring saw comprises a ring saw and an endoscope. The ring saw comprises a head, an outer pipe, a rotating wheel, a main body, a water valve, a ring handle, a pressure spring, a push rod, a locking ring, an endoscope base and a handle. The endoscope comprises an endoscope main body and a pipe body with an object lens. The visual ring saw is characterized in that the head of the ring saw is provided with a self tapping internal thread which is of a hollow structure, the self tapping internal thread is connected with the outer pipe to be a whole, and the end face of the self tapping internal thread is in a sawtooth shape. The visual ring saw is reasonable in structural design, not only can saw bone blocks during the operations, but also can take out the bone blocks sawn and is convenient to use, reliable, safe and good in operational comprehensive effect.
Description
Technical field
This utility model relates to a kind of saw, the visual trepan of a kind of operation particularly, and it belongs to medical apparatus and instruments, is mainly applicable in the spinal operation of human body.
Background technology
In existing spinal operation, main operating theater instruments is visual trepan, it comprises trepan and endoscope, and trepan comprises outer tube, runner, main body, water valve, finger ring handle, stage clip, push rod, lock ring, microscope base and handle, outer tube and runner welding, main body and water valve welding, finger ring handle and push rod are adhesively fixed, and compression spring sleeve is on finger ring handle, and push rod withstands on microscope base, lock ring is threaded connection on microscope base, and microscope base and handle all weld with main body; Endoscope comprises mirror main body and with the body of object lens, object lens are positioned at the front end of body.This visual trepan when operation can only saw sending down the fishbone piece but can not take out of the bone piece under sawing, therefore its structural design is reasonable not, it is also convenient not to use.
Utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and provide, a kind of structural design is more reasonable, use is performed the operation and used visual trepan more easily.
The technical scheme in the invention for solving the above technical problem is: this operation comprises trepan and the endoscope of mutual coupling with visual trepan, trepan comprises outer tube, runner, main body, water valve, finger ring handle, stage clip, push rod, lock ring, microscope base and handle, endoscope mainly comprises mirror main body and with the body of object lens, it is characterized in that: the self-taped type female thread that is provided with hollow structure at the head of described trepan, this self-taped type female thread is connected with outer tube, and the end face of described self-taped type female thread is zigzag.Make thus this utility model when operation can not only saw sending down the fishbone piece can also take out of the bone piece under sawing, easy to use.
Objective of endoscope described in the utility model is positioned at the rear end of self-taped type female thread.
This utility model compared with prior art, have the following advantages and effect: structural design is more reasonable, because the head at trepan is provided with the self-taped type female thread of hollow structure, during operation, can not only saw sending down the fishbone piece can also take out of the bone piece under sawing, easy to use, reliable and safety, the resultant effect of operation is better.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of this utility model trepan.
Fig. 3 is the structure enlarged diagram at Fig. 2 rear portion.
Fig. 4 is that the structure of Fig. 2 head self-taped type female thread is amplified schematic perspective view.
The specific embodiment
Referring to Fig. 1-Fig. 4, this utility model is mainly comprised of trepan ⅠHe endoscope II, and endoscope's II is mated with trepan I, and the body 13 of endoscope's II is positioned at the outer tube 1 of trepan I.
Trepan I of the present utility model comprises outer tube 1, runner 2, water valve 3, finger ring handle 4, stage clip 5, push rod 6, lock ring 7, main body 9, microscope base 10 and handle 8; Outer tube 1 and runner 2 welding, main body 9 and water valve 3 welding, finger ring handle 4 is adhesively fixed with push rod 6, and stage clip 5 is enclosed within on finger ring handle 4, and push rod 6 withstands on microscope base 10, and lock ring 7 is threaded connection on microscope base 10, and microscope base 10 and handle 8 all weld with main body 9.Endoscope's II comprises mirror main body 12 and with the body 13 of object lens 14, object lens 14 are positioned at the front end of body 13.
This utility model is provided with the self-taped type female thread 11 of hollow structure at the head of trepan I, it is connected with outer tube 1, and the end face of self-taped type female thread 11 is zigzag 111.The object lens 14 of endoscope's II head are positioned at the rear end of self-taped type female thread 11.
During use, by the object lens 14 in endoscope's II, can see the bone piece under the saw needing on spinal column clearly, then by self-taped type female thread 11, saw sending down the fishbone pieces and take the bone piece under this saw out of.
All equivalence or simple change of doing according to described structure, feature and the principle of this utility model patent design, are included in the protection domain of this utility model patent.
