Abstract
The invention relates to a retractor for an orthopedic surgery.The retractor comprises a moving rod and a fixed rod, wherein a sliding rod is arranged on the fixed rod, the moving rod comprises a sliding head, the sliding rod penetrates through the sliding head, the sliding head can move along the sliding rod, stationary claws are arranged at the end of the fixed rod and the end of the moving rod, moving claws are arranged on the fixed rod and the moving rod, the fixed rod and the moving rod are sleeved with the moving claws, and fastening bolts are arranged between the moving claws and the fixed rod and the moving rod.Claw hooks are arranged on the moving claws and the stationary claws and are arc-shaped.The claw hooks of the stationary claw and the moving claw on the fixed rod are opposite to the claw hooks of the stationary claw and the moving claw on the moving rod in orientation.The stationary claws are arranged at the end of the fixed rod and the end of the moving rod of the retractor, and the moving claws are arranged on the moving rod and the fixed rod, so that the retractor facilitates adjustment of the distances between the moving claws and the stationary claws according to the actual demands, facilitates tissue retraction at a surgical incision to expose a large surgical view field and facilitates the surgery.
Description
Technical field
The present invention relates to pressure instrument field, specifically a kind of bone surgery retractor.
Background technology
Retractor is a kind of surgical operating instrument, in order to retract tissue, appears surgical field of view, it is simple to detect and operate.Conventional retractor has metal retractors and soft retractor.The double; two pawl retractor of machinery that current surgery is conventional mostly is the metal material such as rustless steel and titanium alloy and makes, and has an advantage in that and can provide very big support force for operative incision and allow use of repeatedly sterilizing.At present, common retractor is in use due to the narrower width of claw hook, unadjustable, and when utilizing the tissue that retractor struts operative incision place, the kerf strutted is tetragon, and surgical field of view is exposed not, inconvenient during operation.And when the otch of operative site is bigger, it is necessary to additionally use drag hook etc. and assist to retract surgical tissue, operate relatively complicated, be unfavorable for performing the operation.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of bone surgery retractor, in the present invention the push rod of retractor and lever are provided with quiet pawl head and pawl head, the distance of the size adjustment pawl head according to operative incision and quiet pawl head, operative incision is retracted into a hexagon, expose bigger surgical field of view, conveniently perform the operation.
The present invention is achieved through the following technical solutions:
A kind of bone surgery retractor, including lever, fixed pole, described fixed pole is provided with slide bar, described lever includes slide head, and described slide bar is through slide head, and slide head can move along slide bar, described fixed pole, lever end be provided with quiet pawl head, being provided with pawl head in described fixed pole, lever, described pawl headgear is contained in fixed pole, lever, is provided with fastening bolt between pawl head and fixed pole, lever.Being provided with claw hook on described pawl head, quiet pawl head, described claw hook is arcuation.
As the preferred technical solution of the present invention, the material of described retractor is 304 rustless steels.
As the preferred technical solution of the present invention, quiet pawl head in described fixed pole, pawl head claw hook towards pawl head quiet with in lever, pawl head claw hook towards contrary.
Compared with prior art, the invention has the beneficial effects as follows: the present invention arranges quiet pawl head in the fixed pole of retractor and the termination of lever, lever, fixed pole arrange pawl head, conveniently regulate the distance between pawl head and quiet pawl head according to actual needs when operation, it is easy to the tissue retraction at operative incision place, expose bigger surgical field of view, conveniently perform the operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, pawl head；2, fastening bolt；3, fixed pole；4, quiet pawl head；5, lever；6, slide head；7, locking member；8, slide bar；9, teeth portion；10, claw hook.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of bone surgery retractor, including lever 5, fixed pole 3, being provided with slide bar 8 in described fixed pole 3, described lever 5 includes slide head 6, described slide bar 8 traverse slide head 6, slide head 6 can move along slide bar 8, slide bar 8 arranges teeth portion 9, slide head 6 is provided with the locking member 7 coordinated with teeth portion, by locking member 7, slide head 6 and slide bar 8 are fixed.Described fixed pole 3, lever 5 end be provided with quiet pawl head 4, described fixed pole 3, lever 5 are provided with pawl 1, described pawl 1 is sleeved in fixed pole 3, lever 5, be provided with between pawl 1 and fixed pole 3, lever 5 fastening bolt 2.When operation, according to the size of otch, the distance between pawl 1 and quiet pawl head 4 is adjusted to correct position, then utilize clamping screw 2 pawl 1 and fixed pole 3, lever 5 to be fixed.Then claw hook 10 is inserted operative incision, mobile lever 5, by incision tissue retraction to correct position, locks slide head 6 and slide bar 8 with locking member 7.
As a preferred embodiment of the present invention, in order to prevent retractor corrosion and be easy to cleaning and sterilizing, the material of described retractor is 304 rustless steels.
As a preferred embodiment of the present invention, described pawl 1, quiet pawl head 4 being provided with claw hook 10, described claw hook 10 is arcuation, and the claw hook 10 of arcuation is easy to the tissue retraction at operative incision place, it is prevented that tissue slips.
As a preferred embodiment of the present invention, for retracting the tissue of incision, quiet pawl head 4 in described fixed pole 3, pawl 1 claw hook 10 towards pawl head 4 quiet with in lever 5, pawl 1 claw hook 10 towards contrary.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
