Abstract
(B, ) the utility model provides a novel puncture needle belongs to the medical instrument field. It has solved the difficult problem in current pjncture needle location. This novel puncture needle, overlap and wear to establish the nook closing member in the needle cover including the needle, still include the locating plate, be equipped with the guiding hole on the locating plate, the guiding hole pore wall is the sphere, and the embedded sphere direction ball that is equipped with of guiding hole, be equipped with the perforation in the direction ball, and perforate along the direction sphere diameter to the setting, direction ball and guiding hole tight fit are connected, and needle cover tight fit is inserted in perforating, and can perforate through direction ball and guiding hole match adjustment and move towards, also can overlap the front end with needle cover match adjustment needle through perforating and wear out fenestrate length. Utilize the nook closing member to remove in the needle overlaps and puncture, because needle cover tight fit is inserted in perforating, pass through direction ball and guiding hole match adjustment perforation orientation simultaneously, consequently can make things convenient for the orientation of adjusting needle cover and nook closing member, also can wear out fenestrate length through perforation and needle cover match adjustment needle cover front end simultaneously, consequently conveniently adjust piercing depth. (B, )
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of Novel puncture needle.
Background technology
Existing puncture needle in operation, when operator wear pricker is inserted into thoracic cavity carry out bleeding or drawing liquid time, a hand-held vascular forceps of assistant is needed to fix puncture needle, in case puncture needle displacement punctures that visceral pleura causes pneumothorax, injured blood vessel causes hemorrhage or puncture needle slippage go out pleural space and need secondary puncture, increase unnecessary misery to patient.Therefore be necessary to improve puncture needle.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and can facilitate the localised puncture degree of depth, simultaneously can the Novel puncture needle of localised puncture angle.
The purpose of this utility model realizes by following technical proposal: a kind of Novel puncture needle, comprise needle guard and be located in the nook closing member in needle guard, it is characterized in that: also comprise location-plate, described location-plate is provided with pilot hole, described pilot hole hole wall is spherical in shape, and in pilot hole, be embedded with spherical SDeflector, perforation is provided with in described SDeflector, and perforation is arranged along SDeflector radial direction, described SDeflector and pilot hole tight fit connection, and needle guard tight fit is inserted in perforation, and by SDeflector and pilot hole coordinate adjustment perforation towards, also to coordinate with needle guard by perforation and adjust the length that needle guard front end passes perforation.
Utilize nook closing member to move in needle guard to puncture, because needle guard tight fit is inserted in perforation, simultaneously by SDeflector and pilot hole coordinate adjustment perforation towards, therefore can conveniently adjust needle guard and nook closing member towards, also to coordinate with needle guard by perforation simultaneously and adjusts the length that needle guard front end passes perforation, therefore facilitate and adjust paracentesis depth, when puncture puts in place, location-plate contacts with skin, supports, and therefore also facilitates single operation.
In above-mentioned a kind of Novel puncture needle, in described perforation, be provided with antislip ring, and antislip ring laminating perforation hole wall is arranged, and fit with needle guard, be provided with slipmat in described pilot hole, and slipmat and SDeflector are fitted.
Therefore can prevent from offseting in piercing process.
In above-mentioned a kind of Novel puncture needle, described pilot hole two ends are all in enlarging shape.
Therefore the angle of convenient adjustment needle guard and nook closing member.
In above-mentioned a kind of Novel puncture needle, described location-plate is cross, and pilot hole is located at location-plate geometric center position, and location-plate geometry corner location is respectively equipped with rubber blanket.
Therefore by rubber blanket and contact skin, can support to utilize location-plate.
Compared with prior art, this utility model tool has the following advantages:
Utilize nook closing member to move in needle guard to puncture, because needle guard tight fit is inserted in perforation, simultaneously by SDeflector and pilot hole coordinate adjustment perforation towards, therefore can conveniently adjust needle guard and nook closing member towards, also to coordinate with needle guard by perforation simultaneously and adjusts the length that needle guard front end passes perforation, therefore facilitate and adjust paracentesis depth, when puncture puts in place, location-plate contacts with skin, supports, and therefore also facilitates single operation.
