Abstract

A manual bone drill channel and orifice shutter under direct vision by vertebral disc mirror comprises a manual bone drill channel under direct vision and an orifice shutter inserted into the manual bone drill channel under direct vision. The manual bone drill channel under direct vision comprises a direct-vision channel which is fixedly connected with a handle; the shape of the cross section of the direct-vision channel is elliptical; the upper port of the direct-vision channel is larger than the lower port and the direct-vision channel deflates as a whole like a taper. The manual bone drill can pass through the direct-vision channel. The orifice shutter comprises an orifice shutter cap and an orifice shutter rod fixedly connected with the orifice shutter cap. The top part of the orifice shutter cap is a sphere surface; the shape of the cross section of the cap body part is elliptical; the shape of the orifice shutter cap matches with the direct-vision channel. The direct-vision channel of the utility model is easy to be fixed, and the manual bone drill can pass through the direct-vision channel, making the surgical operation simple, the speed high, the bleeding less and the complication less. The utility model can complete the operations of the single or the multi-subsection lumbar vertebral disc diseases from L1-2 to L5-S1 and the disease of the side recess stenosis and not injure the dural sac and nerve roots, largely expanding the operation indications of STORZ posterior vertebral disc mirror. The operation is simple and is easily learned.

Description

Medical MED is looked at manual bone drill passage and obturator straight

Technical field

This utility model relates to a kind of operating theater instruments for the treatment of intervertebral disk hernia and spinal stenosis, and particularly a kind of medical MED is looked at manual bone drill passage and obturator matching used with it straight.

Background technology

Posterior intervertebral-disc-scope (MED) operation of treatment intervertebral disk hernia and spinal stenosis, the domestic approaches in the spinous process 1.0-1.5cm paraspinal muscle that adopt more.In way of escape STORZ MED operating theater instruments, the STORZ service aisle is that flat does not have fixture, and the foundation of operation path needs under scope, finish with the rongeur of rifle formula, have operating difficulties, service aisle easily moves, shortcomings such as muscle is easily charged into passage, and is hemorrhage many, and complication is many.Because the STORZ service aisle is flat, can not put into manual bone drill in its service aisle, thereby the STORZ service aisle can not use manual bone drill when performing an operation.

Summary of the invention

The purpose of this utility model provide a kind of can be by manual bone drill service aisle and the obturator that is used with service aisle.

This utility model changes operative approach into spinous process and lamina, and the paraspinal muscle gap design is made as the manual bone drill passage of direct-view.This passage is oval, with assurance and the telescopic optimum matching of operation, and has fixed handle.Simultaneously former STORZ being controlled device (inner core) designs and produces to looking at the obturator that manual bone drill passage is complementary straight, obturator and the supporting use of the manual bone drill passage of direct-view.

Concrete operations are that manual bone drill passage of direct-view and obturator are inserted in the soft tissue, reach lamina surface deeply.Take out obturator then, handle is controlled and the manual bone drill passage of fixing direct-view, through this passage can clear identification vertebral plate gap and ligamenta flava up and down, can worn part vertebral plate and ligamenta flava with manual bone drill, direct-view is the foundation of promptly finishing operation path of removing down.Advantages such as the method has simple to operate, and the direct-view passage is easily fixing, and speed is fast, goes out insufficiency of blood, and complication is few.

The medical MED of this utility model is looked at manual bone drill passage straight and obturator comprises: look at manual bone drill passage straight and insert its interior obturator; Looking at manual bone drill passage straight comprises: the direct-view passage, and the direct-view passage is fixedlyed connected with handle, can pass through manual bone drill in the direct-view passage; Obturator comprises obturator medicated cap and the obturator bar of fixedlying connected with it, and obturator inserts in the direct-view passage.

Look at manual bone drill passage and obturator straight according to described medical MED, it is characterized in that: described direct-view passage is promptly looked at channel cross-section straight for oval for oval, the direct-view passage suitable for reading be ellipse, end opening is oval or circular, and end opening shape and obturator medicated cap are complementary.

Look at manual bone drill passage and obturator straight according to described medical MED, it is characterized in that: described direct-view passage suitable for reading greater than end opening, direct-view passage integral body is tapering and dwindles.

Look at manual bone drill passage and obturator straight according to described medical MED, it is characterized in that: the top of described obturator medicated cap is the ball face, and medicated cap body cross section is oval, is complementary with the end opening of looking at passage straight.

This utility model direct-view passage is easily fixing, can pass through manual bone drill in the service aisle, makes operation technique simple, and speed is fast, and patient goes out insufficiency of blood, and complication is few.This utility model can be finished L1-2 to L5-S1 list or multi-segmental intervertebral disc prolapse and lateral recess syndrome operation goodly, dural sac and nerve root injury can not appear, expanded the operation indication of STORZ posterior intervertebral-disc-scope greatly, and easy simple to operate, promotional value had.

The specific embodiment

This utility model comprises two parts as shown in Figure 1, promptly looks at manual bone drill passage straight and inserts the interior obturator of direct-view passage.Look at manual bone drill passage straight and see shown in Figure 2ly in addition, comprising: direct-view passage 1, direct-view passage 1 is fixedlyed connected with handle 3.Direct-view passage 1 is oval on the whole, promptly looks at channel cross-section straight for oval.Look at the suitable for reading greater than end opening of passage straight, direct-view passage integral body is tapering and dwindles.Certainly, also can be made as straight tubular according to operation needs direct-view passage.The suitable for reading of direct-view passage 1 is oval, and other sees shown in Figure 3, with assurance and the telescopic optimum matching of operation, but also can pass through manual bone drill.Certainly, direct-view the suitable for reading of passage also can be designed to circle as required.The end opening of direct-view passage is circular oval (see figure 4), and is complementary with the obturator medicated cap.

Obturator such as Fig. 5, shown in Figure 6 comprise obturator medicated cap 4 and obturator bar 2, and the shape of obturator medicated cap 4 is complementary with direct-view passage 1.Obturator medicated cap 4 and obturator bar 2 are fixedlyed connected by screw thread, can certainly be welded to connect or manufacture to one.During use, obturator inserts in the manual bone drill passage of direct-view.
