Embodiment Construction

[0023] The present invention will be described in detail below with reference to the drawings and examples.

[0024] Such as Figure 1-2 As shown, the pulp cavity file pulling device of the present invention includes a main body 1, a clamping handle 2 and a clamping head 3 of the pulp cavity file, the main body 1 is connected with the clamping handle 2, and the inside of the clamping handle 2 A shrapnel 4 is provided. The main body 1 expands the clamping handle 2 by pressing the shrapnel 4. The clamping handle 2 is also connected with the clamping head 3 of the medullary cavity file through a shaft. The clamping handle 2 expands Make the pulp cavity file clamping head 3 clamp the pulp cavity file 5 .

[0025] One end of the main body 1 is connected with a pin 7 through the serrated part 6, and the pin 7 and the serrated part 6 pass through the entrance of the tail end of the clamping handle 2 and are arranged in the clamping handle 2. The other end of the main body 1 Push pl...

Abstract

The invention discloses a beating-pulling apparatus for a medullary cavity file. The beating-pulling apparatus comprises a main body, clamping handles and a medullary cavity file clamping head, wherein the main body is connected with the clamping handles; an elastic sheet is arranged in the clamping handles; the main body expands the clamping handles by pressing the elastic sheet; the clamping handles are also connected with the medullary cavity file clamping head through a shaft; and the medullary cavity file is tightly clamped by the medullary cavity file clamping head through the expansion of the clamping handles. The beating-pulling apparatus is stably and firmly connected with the medullary cavity file; in addition, the beating-pulling apparatus is simple to operate, and convenient to clamp, capable of being operated by a single hand, capable of rapidly assembling and disassembling the medullary cavity file, and has the advantages of capability of realizing stable and non-shaking clamping, high clamping force, and low probability of loosening; therefore, iatrogenic injury can be reduced to the minimum, the surgical time can be shortened, and a better surgical effect can be obtained, so that the beating-pulling apparatus can be used conveniently by a doctor as far as possible to reduce pain of a patient and secondary injury to the patient; and consequently, the operation can be accomplished in a quicker, more convenient and safer manner.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device for pulling out a medullary cavity file. Background technique [0002] After more than 30 years of clinical practice, the therapeutic effect of hip replacement has been fully affirmed and developed into a reliable treatment method. Joint replacement is mainly to implant artificial hip joint prosthesis through surgical tools to remove joint position lesions, so as to relieve joint pain, correct deformity, restore and improve joint motion function. [0003] Before implanting the artificial hip joint prosthesis, the cancellous bone in the medullary cavity needs to be removed with a special medullary cavity rasp to provide a place for the prosthesis installation. Because the removal of cancellous bone requires the percussion of external force, and the medullary canal rasp body cannot be knocked during the operation, it is necessary to use the medullary canal ras...
