Abstract
The utility model discloses a measuring instrument used in a surgical operation, particularly a deep measuring scale, which comprises a measuring rod, a scale rod, a screw cap passing through the measuring rod, and a sleeve fitted over the measuring rod and the scale rod. The deep measuring scale is characterized in that a spring is arranged between the screw cap and the sleeve. And the beneficial effects of the utility model are as follows: when measuring the length of a skeleton inner pore, the scale can automatically contract for accurately reading only by placing the hook at the front end of the deep measuring scale in the right position, so that an operator doesn't need to draw back the front end of the deep measuring scale or forwardly push the scale part, and the operation time is remarkably shortened, the measurement efficiency is improved and operation risk of patients is reduced.
Description
(1) technical field
This utility model relates to a kind of surgical operation measuring apparatus, particularly a kind of dipstick.
(2) background technology
In the orthopaedics internal fixation operation, to place screw in the skeleton internal drilling of fracture and fix, the length of screw is consistent with the length of skeleton inner duct.Measure the length of skeleton inner duct and will use dipstick.Dipstick design in the past is accurate inadequately, the dipstick leading hook often will hook soft tissues such as muscle or fascia, by the patient pull back dipstick scale front end or before push away scale portion and can measure, not only the working time is long, and inefficiency, increased patient's operation risk.
(3) summary of the invention
This utility model provides a kind of measurement accurate dipstick in order to remedy the deficiencies in the prior art.
This utility model is achieved by the following technical solution:
A kind of dipstick comprises measuring stick, scale bar and is through nut on the measuring stick, is enclosed within the sleeve on measuring stick and the scale bar, it is characterized in that: be provided with spring between described nut and the sleeve.
The beneficial effects of the utility model: as long as the position of end hook before when measuring skeleton inner duct length, placing dipstick, scale can bounce back automatically, pin-point reading, need not the patient pull back again the dipstick front end or before push away scale portion, shortened operating time greatly, improve and measure efficient, reduce the corrective surgery risk, save health resources.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 measuring stick, 2 scale bars, 3 nuts, 4 springs, 5 sleeves.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises measuring stick 1, scale bar 2 and is through nut 3 on the measuring stick 1, is enclosed within the sleeve 5 on measuring stick 1 and the scale bar 2, it is characterized in that: be provided with spring 4 between described nut 3 and the sleeve 5.The patient uses hand push dipstick scale portion during operation, insert the dipstick leading hook in the skeleton duct and hook skeleton oppose side wall cortical bone, loose one's grip, improvement dipstick inner spring automatically springs open, improvement dipstick nut promptly withstands on skeleton boring side, and scale afterbody reading is a skeleton inner duct length.This dipstick is mounting spring in sleeve, as long as the position of end hook before when measuring skeleton inner duct length, placing dipstick, scale can bounce back automatically, pin-point reading, need not the patient pull back again the dipstick front end or before push away scale portion, shortened operating time greatly, increase work efficiency, reduce the corrective surgery risk, save health resources.
Claims (1)
1, a kind of dipstick, comprise measuring stick (1), scale bar (2) and be through nut (3) on the measuring stick (1), be enclosed within the sleeve (5) on measuring stick (1) and the scale bar (2), it is characterized in that: be provided with spring (4) between described nut (3) and the sleeve (5).
