Description
Technical field
The present invention relates to medical instruments field, dilator under particularly a kind of endoscope.
Background technology
In recent years; Develop rapidly along with the neural navigation system of neuroimaging, nerve endoscope manufacturing process, micro-surgical instruments and stereotaxis; Make that the operation method of auxiliary three ventriculostomys of nerve endoscope is increasingly mature; Indication is constantly widened, and plays a greater and greater role in noncommunicating hydrocephalus operative treatment field.Three ventriculostomys mainly are applicable to the noncommunicating hydrocephalus fistulation; Also can be used to shunt the noncommunicating hydrocephalus patient of failure or isocon infection adhesion; Stop up and cause the patient of shunting failure for isocon repeatedly, three ventriculostomys are undoubtedly a kind of excellent alternative medicine.
Be to improve the safety and the effectiveness of operation, except the suitable hydrocephalus patient of correct selection and operation method on top of and operation skill, the operating theater instruments that the employing high-quality suits also is the successful keys of three ventriculostomys.A step very crucial in the process of whole surgery is fistulation, and promptly through the help of operating theater instruments such as neuroendoscopy, on the ventriculus tertius basement membrane, making a diameter is the fistula mouth of 5mm to 6mm.The complication rate of three ventriculostomys is low than bypass on the whole, about 5% to 7%, comprises mainly that the art medium-sized vein is hemorrhage, basilar artery break, postoperative intracranial hemorrhage, infection, of short duration loss of consciousness or hypothalamic function be low, is mostly one to cross property.Wherein the most dangerous complication is exactly that basilar artery and branch thereof break and cause massive hemorrhage.Sharp property such as probe fistulation technology fistulation is easy and effective, but misoperation very easily causes blood vessel and brain tissue impairment, for avoiding in operation, damaging basilar artery, adopts sacculus dilating catheter eleven punch 11 fistulation in the prior art usually.
But inventor of the present invention finds, adopts sacculus dilating catheter eleven punch 11 fistulation, because the conduit quality is softer; The blunt circle of head end often is difficult to break through basement membrane, and is special because of balloon material simultaneously; Price is more expensive, and damages easily, and recycling rate of waterused is very low; Bring very big inconvenience to clinical position, especially for the very tough or very resilient patient of three ventricles of the brain basement membrane, operation has also increased the risk of operation times without number.Therefore need seek a kind of new fistulation apparatus, when guaranteeing the fistulation effect, improve the safety and the ease for operation of operation.
Summary of the invention
The object of the present invention is to provide dilator under a kind of endoscope, utilize an operating theater instruments just can realize the function of poking and strutting, structural design is simple, and operation technique is more simple and convenient, and surgical effect is more safe and effective.
For solving the problems of the technologies described above; Embodiment of the present invention discloses dilator under a kind of endoscope, comprising: first hand holding handle (1), second hand holding handle (2), bolt (4), pin (16), hollow pipe (6), catch bar (7), the first dilator head (8), the second dilator head (9) and connecting plate (11);
Catch bar (7) places the centre bore of hollow pipe (6);
The first dilator head (8) and the second dilator head (9) are symmetric shape; Both have the calabash shape at the blunt tip of circle (15) to fashionable formation; The mid portion of this calabash shape (13) is hung carefully; Expand anterior (14) and rear portion (12), and rear portion (12) diameter is greater than anterior (14) diameter;
First hand holding handle (1) links to each other through bolt (4) with second hand holding handle (2);

The first dilator head 8 and the second dilator head 9 link together, and cooperatively interact, and can open and can close, and be when both have the calabash shape of justifying blunt tip to fashionable formation, as shown in Figure 2.
Specifically, when both are combined to form the calabash shape that has the blunt tip of circle,
Blunt most advanced and sophisticated 15 the length of circle is 1mm to 2mm, and diameter is 0.1mm to 0.3mm.
Anterior 14 length is 2mm to 3mm, and diameter is 0.4mm to 0.6mm.
The diameter of mid portion 13 is 0.2mm to 0.4mm.
The length at rear portion 12 is 5mm to 8mm, and diameter is 0.8mm to 1.5mm.
When dilator strutted, shape was as shown in Figure 1: when this dilator head calabash shape struts, strut the diameter maximum and can reach 5mm to 8mm.
First hand holding handle 1 links to each other through bolt 4 with second hand holding handle 2.
In addition, also comprise: tooth plate 10, in the couple positioned opposite of first hand holding handle 1 and second hand holding handle 2 tooth plate 10 is arranged, this tooth plate 10 is provided with the multiple tooth snap close that cooperatively interacts.
Be provided with the tooth plate of the multiple tooth snap close that cooperatively interacts in the inboard of hand holding handle, through the fixing position of hand holding handle, the width of control dilator head folding is convenient to control the size that struts mouthful, make operation technique more accurately, convenient.
Certainly, this is of the present invention preferred embodiment a kind of, and in some other embodiment of the present invention, tooth plate 10 can not have yet.
In addition, also comprise: hand-held ring 3 is connected one respectively at the end of first hand holding handle 1 and second hand holding handle 2 and hand-heldly encircles 3.
End at hand holding handle is provided with hand-held ring, is in order to be convenient to hand-held and operation technique more.
Likewise, this is of the present invention preferred embodiment a kind of, and in some other embodiment of the present invention, hand-held ring 3 can not have yet.
In addition, also comprise: runner 5, runner 5 are fixed on first hand holding handle 1, and runner is used for the head of unitary rotation dilator, are convenient to more effectively expose surgical field of view, make operation technique easier.
The rear portion of the rear portion of the first dilator head 8 and the second dilator head 9 is through pin 16 and connecting plate 11 pin joints; Connecting plate 11 also is connected with an end of catch bar 7 through bolt 4; Specifically; Connecting plate 11 is the shapes that connect into parallelogram through bolt 4, and an angle of the rear portion of the rear portion of the first dilator head 8 and the second dilator head 9 and this parallelogram is through pin 16 pin joints, and the diagonal angle at this angle is connected with an end of catch bar 7 through bolt 4.The other end of catch bar 7 is connected with runner 5.
Likewise, this is of the present invention preferred embodiment a kind of, and in some other embodiment of the present invention, connecting plate 11 can not be the shape that connects into parallelogram also, and runner 5 can not have yet.Under the situation that does not have runner 5, the other end of catch bar 7 with directly be connected with first hand holding handle 1.
