Abstract

The utility model relates to the technical field of medical equipment, specifically be a spatula for bone surgery, the head is a spoon head, and the intermediate part be a spoon pole, and the afterbody is a spoonful handle, spoon head be half spoonful of form, a side of this spoonful of head be sharp limit, all the other sides along being the pitch arc limit. The beneficial effects of the utility model are that, the shape of half spoonful of form of spoon head makes it when striking off canalis spinalis oppression thing, can effectively avoid partial spinal cord position and nerve root tissue, reduce avoid even since a spoon head to the spinal cord with the nerve root tissue is oppressed and cause nature spinal nerve in doctor source to harm when striking off.

Description

A kind of bone surgery spatula

Technical field

This utility model relates to technical field of medical instruments, specifically a kind of bone surgery spatula.

Background technology

The working position ovalize of existing spatula, and mostly is straight line and is connected between connecting rod, do not have radian or angle, be applicable to striking off as the spinal column such as tumor tissues, hyperosteogeny compressing thing.But, spatula is when striking off canalis spinalis compressing thing, its ellipsoidal structure easily oppresses spinal cord and nerve root, cause iatrogenic injury of spinal nerves, and the size of existing oval spoon shape spatula and width relatively large, in actual operation operating process, as less wound, thoroughly can not scrape the soft tissue in fracture line, affect the environment of knitting, be unfavorable for the later stage healing of bone.Moreover, the linear design between spatula working position and handle uses and does not meet human engineering, is unfavorable for the use of operator.

Application number is " 201420748858.1 ", Authorization Notice No. is " CN204274566U ", name is called that the Chinese utility model patent of " a kind of dual-purpose curet for bone surgery " discloses a kind of dual-purpose curet for bone surgery, its one end is oval spoon shape curet, the other end is zigzag curet, two ends curet is connected by middle connecting rod, and the angle of described oval spoon shape curet end and connecting rod is 15-20 degree.One end of this dual-purpose curet is oval spoon shape curet, and the other end is zigzag curet, and when the shape of its oval spatula strikes off canalis spinalis compressing thing, easily compressing spinal cord and nerve root, cause iatrogenic injury of spinal nerves.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, when providing a kind of residue after striking off ossified ligament and titanium rete, avoids the spatula of iatrogenic compressing or shock spinal cord and nerve root tissue.

In order to achieve the above object, this utility model provides a kind of bone surgery spatula, and head is spoon head, and pars intermedia is spoon bar, and afterbody is kettleholder, and described spoon head is half spoon shape, and a side of this spoon head is straight line, all the other lateral edges are camber line limit.

Preferably, the camber line limit of described spoon head is provided with sawtooth.

The inner concave of described spoon head is towards spoon bar lateral buckling.

Preferably, described spoon bar is marked with graduation mark.

Preferably, described kettleholder is provided with anti-skidding lines.

The beneficial effects of the utility model are, the shape of half spoon shape of spoon head makes it when striking off canalis spinalis compressing thing, effectively can avoid part spinal cord position and nerve root tissue, reduce and even avoid owing to causing iatrogenic injury of spinal nerves to spinal cord and nerve root tissue compression when spoon head is struck off.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described further.

Embodiment 1:

A kind of bone surgery spatula, head is spoon head 1, and pars intermedia is spoon bar 2, and afterbody is kettleholder 3, and described spoon head 1 is half spoon shape, and a side of this spoon head 1 is straight line 11, all the other lateral edges are camber line limit 12.

The camber line limit 12 of described spoon head 1 is provided with sawtooth 4.

Described spoon bar 2 is marked with graduation mark 5.

Described kettleholder 2 is provided with anti-skidding lines 6.The shape of half spoon shape of this spoon head 1 makes it when striking off canalis spinalis compressing thing, effectively can avoid part spinal cord position and nerve root tissue, reduces and avoid owing to causing iatrogenic injury of spinal nerves to spinal cord and nerve root tissue compression when spoon head 1 is struck off.

Embodiment 2:

All the other are with embodiment 1, a kind of bone surgery spatula, and the inner concave of described spoon head 1 is towards spoon bar 2 lateral buckling.Different models can be made according to the angle between spoon head 1 from spoon bar 2, coordinate actual needs during operation to select corresponding spatula.

Below the preferred embodiment that this utility model is created is illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
