Abstract
The utility model discloses a kind of ligamentum flavum to sting except pincers, including determining claw beam (2), dynamic claw beam (1) and handle (3), determining claw beam (2) front end has occlusion portion (21), occlusion portion (21) central openings, moving on the front end face of claw beam (1) has a lug boss (11) that can be embedded in occlusion portion (21).The specially designed tong head of the utility model can effectively clamp ligamentum flavum, and ligamentum flavum is fallen into the square hole of occlusion portion after being snapped into, and is pushed down to form stable occlusion by lug boss, and ligamentum flavum is difficult to deviate from.
Description
Technical field
The utility model relates to medical instrument articles fields, more particularly to a kind of tong head of laminectomy rongeur.
Background technique
Ligamentum flavum is one layer of fine and close yellow connective tissue, and proximal end arises from upper vertebral plate lower part depth face, distally terminates in bottom
Vertebral plate top superficial surface, inside is combined together with interspinous ligament.In spinal surgery, subtract in laminectomy for decompression or windowing
During pressure, ligamentum flavum between vertebral plate need to be cut off, usually with laminectomy rongeur by ligamentum flavum tear come.
Presently, there are the problem of be laminectomy rongeur clamping ligamentum flavum when be easy slip, clamping do not live ligamentum flavum.
Summary of the invention
Technical problem to be solved by the utility model is: holding eely ask when for laminectomy rongeur clamping ligamentum flavum
Topic, provides a kind of improved end tong head.
The technical solution of the utility model is:
A kind of ligamentum flavum is stung except pincers, including determines claw beam, dynamic claw beam and handle, and determining claw beam front end has an occlusion portion, in occlusion portion
Aperture is entreated, has a lug boss that can be embedded in occlusion portion on the front end face of dynamic claw beam.
Lug boss is a square, occlusion portion center opening square hole.
The cross section for determining claw beam and dynamic claw beam constitutes a circle, and foramen intervertebrale lens or backbone scope can be inserted.
The outer profile size of lug boss is less than the size of occlusion portion mesoporous.
Determining claw beam upper surface, occlusion portion inner side end and lug boss front end face may be constructed a triangle.
Occlusion portion inner side end and the angle for determining claw beam are 90-120 °.
The utility model has the beneficial effects that
Specially designed tong head, can effectively clamp ligamentum flavum, and ligamentum flavum falls into occlusion portion after being snapped into
It in square hole, and is pushed down to form stable occlusion by lug boss, ligamentum flavum is difficult to deviate from.The occlusal surface of binding clip have one it is inside
Inclination angle can inwardly squeeze ligamentum flavum during occlusion, and ligamentum flavum is deviate from during further placing occlusion.
Detailed description of the invention:
Fig. 1 is tong head schematic diagram.
Fig. 2 is the structural schematic diagram of embodiment 2.
Fig. 3 is the vice body schematic shapes of embodiment 3.
Specific embodiment
Embodiment 1: the hand-held and drive mechanism in the present embodiment does not make improvements, and only improves laminectomy rongeur front end
Tong head, for conventional open perform the operation.
Vice body is formed by determining claw beam 2 and dynamic claw beam 1, and it is fixed on the handle 3 to determine claw beam 2, determine claw beam 2 and dynamic claw beam 1 it
Between by sliding slot and sliding block realization be slidably matched, determine 2 rear end of claw beam and lever 4 connection.It is equipped between lever 4 and handle 3 multiple
Position spring.There is cam in 4 upper end of lever, and cam withstands on dynamic 1 rear end of claw beam, and dynamic 1 rear end of claw beam is equipped with reset spring, presses lever
4 can push dynamic claw beam 1 to be engaged, and reset under the action of the spring after release.There are occlusion portion 21, occlusion portion determining 2 front end of claw beam
Thickness is in 2-5mm, occlusion portion central openings, this hole side of being, has a lug boss 11 can be on the front end face of dynamic claw beam 1
It is embedded in occlusion portion, lug boss 11 and occlusion portion 21 will form a circle gap after cooperating.
Embodiment 2: embodiment 2 on the basis of embodiment 1, further makes improvements, the inner side end of occlusion portion 21 and
Determine have an inclination angle between claw beam 2, also has a mutually matched inclined-plane at 80 ° or so, while in the end of dynamic claw beam 1, but
It is that the front end face of 1 front end lug boss 11 of claw beam also has forward an inclination angle, in this way when lug boss 11 is engaged to occlusion portion 21,
It will form the interior occlusal surface gripped, prevent ligamentum flavum from skidding off.
Embodiment 3: the present embodiment is to be suitable under foramen intervertebrale lens and under other intraspinal mirrors (the big channel such as Delta),
And can be used under spinal endoscopes, therefore vice body is circle, diameter is according to foramen intervertebrale lens or the diameter of other backbone scopes
Depending on.Vice body is formed by determining claw beam 2 and dynamic claw beam 1, is determined claw beam 2 and is fixed on the handle 3, determines to lead between claw beam 2 and dynamic claw beam 1
It crosses sliding slot and sliding block realization is slidably matched, determine 2 rear end of claw beam and lever 4 couples.Reset bullet is installed between lever 4 and handle 3
Spring.There is cam in 4 upper end of lever, and cam withstands on dynamic 1 rear end of claw beam, and dynamic 1 rear end of claw beam is equipped with reset spring, and pressing lever 4 can
To push dynamic claw beam 1 to be engaged, resetted under the action of the spring after release.There are occlusion portion 21, occlusion portion thickness determining 2 front end of claw beam
In 2-5mm, occlusion portion central openings, this hole side of being has a rectangular lug boss 11 can on the front end face of dynamic claw beam 1
To be embedded in occlusion portion, lug boss 11 and occlusion portion 21 will form a circle gap after cooperating.
