Abstract
The utility model discloses a high-viscosity bone cement filler. The filler comprises a stirring barrel, an inner sleeve and a pressing sleeve, wherein the inner sleeve is arranged in the stirring barrel and can slide along the inner wall of the stirring barrel; the inner wall of the stirring barrel is tightly bonded with the outer wall of the inner sleeve; the pressing sleeve is sleeved outside the stirring barrel; the inner wall of the pressing sleeve is in threaded connection with the outer wall of the stirring barrel; and an inner flange for limiting the inner sleeve is arranged on the upper end face of the pressing sleeve. The high-viscosity bone cement filler can be used for blending and filling bone cement; the high-viscosity bone cement blended in the stirring barrel can be filled into a needle cylinder of an injector without other tools except the filler, and the filling process is quite labor-saving; and when the high-viscosity bone cement is injected into human bones, the recovery period of patients is shortened, and the operation result is greatly improved.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of high viscosity bone cement tucker, is the auxiliary accessories of bone cement injector.
Background technology
Bone cement injector is a kind of former of compression fracture of vertabral body, vertebral body that osteoporosis causes or medical apparatus and instruments of the disease surgeries such as metastatic tumo(u)r, myeloma of being applied to, it is a kind of non-blood vessel interventional therapy method under radioactivity is image-guided, the method is passed through percutaneous puncture, bone cement is expelled in diseased vertebral body, stablize vertebral body, thereby reach the purpose for the treatment of.
Before operation, bone cement need to be formulated in the syringe that certain concentration is filled to bone cement injector, the mode that generally extracts by syringe can only be loaded the rarer bone cement liquid of viscosity, the hands postoperative patient restore cycle is long, only have bone cement viscosity when injection when higher, could shorten patient's restore cycle, but bone cement viscosity is when high, be loaded into syringe just more difficult, the mode of extraction is the filling of inapplicable high viscosity bone cement obviously.
The utility model content
The utility model purpose: the purpose of this utility model is for the ease of full-bodied bone cement being filled in the syringe of syringe, a kind of high viscosity bone cement tucker being provided.
Technical scheme: high viscosity bone cement tucker described in the utility model, its objective is such realization, a kind of high viscosity bone cement tucker, comprise mixing drum, inner sleeve and pressure cuffs, described inner sleeve is built in mixing drum, can slide along the mixing drum inwall, the inwall of mixing drum and the outer wall of inner sleeve fit tightly, described pressure cuffs is coated at outside mixing drum, and the inwall of pressure cuffs and mixing drum outer wall are threaded connection, and the upper surface is provided with the inner flange of spacing inner sleeve.
On described pressure cuffs inwall, eaves is provided with buckle, and inner sleeve outer wall upper end is provided with the catching groove suitable with buckle, inner sleeve and pressure cuffs clamping.
Described inner sleeve bottom is provided with the threaded mounting hole that coordinates with the injector syringe afterbody.
operation principle: complete the allotment of bone cement in mixing drum, the tail end of syringe cylinder is fixed in the threaded mounting hole of inner sleeve, pressure cuffs is sleeved on outside mixing drum, the upper end that the inner flange that arranges due to the pressure cuffs upper surface has withstood inner sleeve, when tightening pressure cuffs, pressure cuffs drives inner sleeve and moves to the mixing drum bottom surface together, make the partial pressure increase of filling bone cement between inner sleeve bottom and mixing drum bottom surface, bone cement i.e. threaded mounting hole bottom inner sleeve enters in injector syringe, until inner sleeve bottom and mixing drum bottom surface applying, bone cement in agitator all is filled in injector syringe.
Beneficial effect: high viscosity bone cement tucker described in the utility model, can carry out allotment and the filling process of bone cement, the bone cement that is in harmonious proportion in mixing drum, need to just full-bodied bone cement can be filled to injector syringe inside by other instruments outside the design, and the filling process is quite laborsaving, full-bodied bone cement is expelled in skeleton, has shortened patient's restore cycle, and surgical effect is very significantly improved.
