The scraping ring comprises a handle (1), a neck rod (2) and a ring (3), wherein the handle (1) is connected to the neck rod (2); the ring (3) is fixedly connected to the tail end of the neck rod (2); the neck rod (2) is a telescopic rod; and a tightening ring (4) is used for fixing and adjusting the length of the neck rod (2). Compared with the prior art, the length can be changed at any time according to the specific position of the tumor in the operation process, the operation is convenient and time-saving, and the pituitary adenoma operation efficiency is efficiently increased.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of length-adjustable circle of scraping.
Background technology
As everyone knows, pituitary adenoma is one of a kind of commonly encountered diseases in the neurosurgery field and frequently-occurring disease, health is produced harm greatly, at present, trans-nasal-sphenoidal approach is the most frequently used a kind of modus operandi in the pituitary adenoma operation, can ensure the Wicresoft of operation to greatest extent, the excision degree of safety and tumor, in nose butterfly approach operation process, scrape the effect that can not be substituted that enclosing, the traditional circle of scraping all is the integrated design, and a general cover is divided into 4 to 6, the circle of scraping that comprises various different lengths, in the actual operation operating process,, lose time according to the circle of scraping of the continuous conversion different length of depth needs of tumor, inconvenient operation, influence operation efficient.
Summary of the invention
The purpose of this utility model is exactly that a kind of circle of scraping of being convenient to adjust length will be provided.
A kind of circle of scraping, it comprises handle, neck bar, circle, and handle connects with the neck bar, and circle is fixedly connected at neck bar end, and the neck bar is an expansion link.
Described expansion link comprises that two joint connecting rods are socketed to form, the outer tie rod bottom is provided with bunching ring, bunching ring and outer tie rod thread connection, the outer tie rod bottom is for having externally threaded and the collapsible version of internal diameter, this version realizes by the thread barrel that has the slit, move the bunching ring position, and then the thread barrel gap size changes, and then makes internal diameter varies.
Two joint connecting rods of described expansion link are provided with graduation mark.
Than the existing integrated circle of scraping, this utility model provides scrapes circle, can be according to the particular location degree of depth of tumor in the operation, reach the purpose that rapid adjustment is scraped the circle degree of depth by adjusting expansion link, effectively shorten the time of operation and anesthesia, reduced the patient suffering, improved operation efficient.
Description of drawings
Fig. 1 is this utility model example structure sketch map.
The specific embodiment
As shown in the drawing: a kind of circle of scraping, it comprises handle 1, neck bar 2, circle 3, and handle 1 connects with neck bar 2, and circle 3 is fixedly connected at neck bar 2 ends, and neck bar 2 is an expansion link.
Described expansion link comprises that two joint connecting rods are socketed to form, the outer tie rod bottom is provided with bunching ring 4, bunching ring 4 and outer tie rod thread connection, the outer tie rod bottom is for having externally threaded and the collapsible version of internal diameter, this version realizes that by the thread barrel that has the slit bunching ring 4 positions are moved, and then the thread barrel gap size changes, and then outer tie rod bottom internal diameter varies, internal diameter are diminished outer tie rod and inside connecting rod are fixed together.
Two joint connecting rods of described expansion link are provided with graduation mark, make the length adjustment of expansion link more accurate.
Originally scraping circle can reach the purpose that rapid adjustment is scraped the circle degree of depth by adjusting expansion link according to the particular location degree of depth of tumor in the operation, has effectively shortened the time of operation and anesthesia, reduces the patient suffering, improves operation efficient.
