Description

Technical Field

[0001] This utility model relates to a solid drug delivery device, and more particularly to a solid drug delivery device. Background Technology

[0002] Most bone meal fillers used in the prior art adopt a fixed integrated structure design. This fixed integrated bone meal filler has good integrity and high stability. However, during use, the bone meal filling device cannot be accurately and evenly pushed, which affects the filling quality and effect. At the same time, the bone meal is prone to clumping inside the filling cylinder.

[0003] As disclosed in prior art CN200920267776.4, a handheld component is rod-shaped; a holding component extends from one end of the handheld component and has a groove at its end; and a filling component extends from the other end of the handheld component in a bent shape and has a pressure surface at its end. Utility Model Content

[0004] This invention addresses the issue that most existing bone powder fillers adopt a fixed, integrated structural design. While this type of bone powder filler has good integrity and high stability, it cannot accurately and evenly control the feeding process during use, thus affecting the filling quality and effect. In addition, the bone powder is prone to clumping inside the filling cylinder. This invention provides a solid delivery device.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A solid drug delivery device includes a fixed filler delivery unit and a solid filler storage unit; wherein the fixed filler delivery unit is located inside the solid filler storage unit and is slidably connected to the inner wall of the solid filler storage unit, and the fixed filler delivery unit is used to deliver solids in the solid filler storage unit to the filler outlet; the end of the solid filler storage unit is provided with an arc-shaped absorbable membrane.

[0007] By slidingly connecting the inner walls of the fixed filler delivery unit and the solid filler storage unit, this system is used during bone powder filling by doctors. The sliding connection between the inner walls of the fixed filler delivery unit and the solid filler storage unit integrates storage and delivery, simplifying the operation process. The use of an arc-shaped absorbable membrane enhances the positioning accuracy of the filler, reduces material waste, and promotes the continuous release of bioactive substances.

[0008] Meanwhile, the curved membrane not only serves as an outlet barrier, but also prevents complications caused by premature exposure or delayed absorption.

[0009] Preferably, the fixed filler delivery unit includes a pushing unit, and the end of the pushing unit is tapered. The tapered pushing end allows for progressive compression of the filler, reducing pushing resistance, making it particularly suitable for minimally invasive bone defect filling procedures in narrow cavities.

[0010] Preferably, the length of the push unit is 15cm-20cm; the fixed filler delivery unit is a circular push unit; and the inner diameter of the push unit is 0.5cm-0.7cm.

[0011] Preferably, the inner diameter of the solid filler storage unit is 0.8cm-1.2cm, and the inner diameter of the solid filler storage unit is larger than the inner diameter of the push unit; the length of the solid filler storage unit is 13cm-17cm.

[0012] Preferably, the inner diameter of the solid filler storage unit is larger than the inner diameter of the pusher unit. By making the inner diameter of the storage unit larger than the pusher unit, an annular gap is formed, preventing jamming caused by lateral compression of the filler.

[0013] Preferably, the length of the solid filler storage unit is shorter than the length of the push unit.

[0014] Preferably, the solid filler storage unit has a scale marker in the middle, and the scale marker is made of PEEK material. The scale marker on the outer surface of the solid filler storage unit enables precise control of the filling amount, which is especially suitable for medical scenarios where a fixed amount of bone powder needs to be filled and precisely implanted according to the volume of the defect.

[0015] This utility model, by adopting the above technical solution, has the following significant technical effects:

[0016] This invention relates to a solid drug delivery device that integrates storage and delivery by slidingly connecting the inner wall of a fixed filler delivery unit and a solid filler storage unit during bone powder filling. This slidable connection simplifies the operation process. The inclusion of an arc-shaped absorbable membrane enhances filler positioning accuracy, reduces material waste, and promotes the continuous release of bioactive substances.

[0017] This invention utilizes a designed tapered push end to progressively compress the filler, reducing pushing resistance. It is particularly suitable for minimally invasive bone defect filling procedures in narrow cavities. Attached Figure Description
