Abstract
The utility model relates to a general-purpose gun-shaped vertebral rongeur, which is mainly used in minimally invasive spine surgery and consists of handle and nose. The handle comprises a front handle 10 and a rear handle 11 which are hinged with each other. A rear pushing rod 9 is positioned at the upper part of the hinge point on the front handle, and a rotation groove 7 is arranged on the rear pushing rod. Front A front base frame 4 and a rear base frame 6 with top opening are positioned at the upper end of the hinge point on the rear handle. The rear part of a lower rongeur beam 8 is positioned in the open grooves of the front base frame and the rear base frame. Anti-revolving apparatus 5 of the compressed beam is arranged outside the lower rongeur beam between the front base frame and the rear base frame. The rear end of the upper rongeur beam 3 travels through the rear part of the lower rongeur beam and is hinged in the rotation groove 7. Front nose 1 is arranged at the front end of the lower rongeur beam. A radian is arranged between the lower rongeur and the front nose at the front end with an included angle ranging from 60 DEG to 120 DEG. The utility model is rotatablerotable, dismountable and is provided with jaws with radian and noses with of various angles. Hence, the aim of increasing operation space and eliminating 'blind area of apparatus' for intervertebral disc scope is achieved.
Description
One, technical field
This utility model is a kind of universal rifle formula laminectomy rongeur that is mainly used in the vertebral column minimally invasive surgery, belongs to the technical field that medical apparatus and instruments is made.
Two, background technology:
Endoscopic technique is being brought into play more and more important effect in the diagnosis and the treatment field of medical science.Edmund Frank in 1997 at first uses through the capable TV direct-view of vertebral plate gap MED and directly extracts vertebral pulp art (Microendoscopic discectomy down, MED), the advantage of melting traditional operation and modern less invasive techniques is in one, applied in countries such as America and Europes very soon, China's various big hospital begins to introduce this surgery systems in recent years.But the zone one " apparatus blind area " that this system visual field exists apparatus not arrive, the method that overcomes at present the apparatus blind area in the operation be will operate by force pipeline up and down, left and right mobile, yet this mobile scope is limited after all, vertebral plate surrounding bone structure is uneven simultaneously, limit moving of operation pipeline, and increased operating time, also may damage apparatus, cause tissue injury, so can not implement operation expediently.Therefore, the proprietary apparatus of necessary development one cover is eliminated " apparatus blind area ".Rifle formula laminectomy rongeur (being called for short the rifle pincers) is that the MED operating theater instruments mainly one of is formed, the subject matter that it exists has the jaw opening direction single, lack certain radian between claw beam and the jaw, the jaw opening lacks various angles, the complex structure of anatomy of spine simultaneously, make the rifle pincers can not arrive mirror downward view peripheral region, so its defective on manufacturing and designing is the main cause that the apparatus blind area occurs.
Three, summary of the invention
1, technical problem
For overcoming the defective of existing rifle pincers, this utility model is rotatable, detachably change various angle jaws adapt to the various band radian of minimally invasive spine surgicals binding clip, universal rifle formula laminectomy rongeur, reach and increase the operation technique space, the purpose of elimination MED " apparatus blind area ".
2, technical scheme
This utility model is a kind of universal rifle formula laminectomy rongeur, formed by handle portion and jaw part, handle portion is formed by front hand grip and back handle cross-articulation, is the back catch bar on the cross-articulation point top of front hand grip, is provided with the rotation groove on the catch bar of back; In the cross-articulation point upper end of back handle is the preceding pedestal and the back pedestal of upper opening, the open slot of pedestal and back pedestal before the rear portion of following claw beam is arranged in, outside the following claw beam of depression bar Device for preventing rotation between preceding pedestal and back pedestal, the rear portion that claw beam is passed down in the rear end of last claw beam is articulated in the rotation groove, and the front end of infra claw beam is provided with preceding jaw.
3, beneficial effect
Universal rifle formula laminectomy rongeur of the present utility model has rotatable, detachably changes various angle jaws, band radian binding clip, can solve because of the anatomy of spine complex structure, and endoscope is the little problem of operation jaw activity space down.Can reach and increase the operation technique space, the purpose of elimination MED " apparatus blind area ".
Four, description of drawings
Fig. 1 is a contour structures sketch map of the present utility model.Wherein have: preceding rifle mouth 1, back jaw 2, go up claw beam 3, preceding pedestal 4, depression bar Device for preventing rotation 5, back pedestal 6, rotation groove 7, claw beam 8, back catch bar 9, front hand grip 10, back handle 11, spinning ball 12, card 13, draw-in groove 14, spring leaf 15, depression bar screw 16 down.
Fig. 2 is the axial sectional structure sketch map of this utility model along last claw beam 3.
Fig. 3 be among Fig. 1 A-A to the sectional structure sketch map.
Five, the specific embodiment
This utility model is a kind of universal rifle formula laminectomy rongeur, formed by handle portion and jaw part, handle portion is formed by front hand grip 10 and back handle 11 cross-articulation, is back catch bar 9 on the cross-articulation point top of front hand grip 10, is provided with rotation groove 7 on the catch bar 9 of back; In the cross-articulation point upper end of back handle 11 is the preceding pedestal 4 and the back pedestal 6 of upper opening, the open slot of pedestal 4 and back pedestal 6 before the rear portion of following claw beam 8 is arranged in, outside the following claw beam 8 of depression bar Device for preventing rotation 5 between preceding pedestal 4 and back pedestal 6, the rear portion that claw beam 8 is passed down in the rear end of last claw beam 3 is articulated in the rotation groove 7, the front end of infra claw beam 8 is provided with preceding jaw 1, and angle is 60～120 degree between the preceding jaw 1 of following claw beam 8 and front end.
The technical scheme that its technology that solves this utility model adopts is: go up the claw beam tail end and be set to spinning ball, back pedestal setting upwards, to the cylinder rotation groove of open front, rotation claw beam, the purpose that changes the jaw opening direction then can be rotated realization by spinning ball in groove.Preceding pedestal is set to two tandem semi-spherical grooves, hold and clamp the thick stick lap up and down, clamping thick stick lap structure up and down is that claw beam holds claw beam down, following claw beam is partly made two types of hexahedron and cuboids, can paste the semi-spherical grooves rotation, the depression bar counter rotation device is set between two small bases, fixes with anti-rotary screw after 60 ° or 90 ° of the every rotations of claw beam when changing the jaw opening direction.The fluting that the front and back pedestal makes progress can be realized the binding clip purpose of dismounting and change different model.Keep certain radian and the various angles of jaw opening (60 °, 75 °, 90 °, 105 °, 120 °) can satisfy between claw beam and the jaw because of spinal operation anatomical structure complexity, the demand that the jaw activity space is little.
