The present invention is described in further detail below with reference to the drawings to enable those skilled in the art to practice the invention by referring to the description.
This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed in breadth and scope in accordance with the appended claims. In the drawings, the size and relative sizes of structures and regions may be exaggerated for clarity.
As shown in fig. 2 to 6, the present invention provides a intramedullary cavity rasping and pulling device, the main structure of which includes: a intramedullary canal file locking mechanism 100 and a reaming mechanism 200; wherein, beat and pull out mechanism 200 and marrow cavity file locking mechanism 100 are connected, beat and pull out mechanism 200 includes: a shank 210 fixedly connected coaxially with the main body structure 110 of the intramedullary file locking mechanism 100; a sleeve 220 is slidably sleeved on the handle body 210, and is of a hollow structure, and the top surface of the hollow structure and the top surface of the handle body 210 are arranged at intervals; a first spring 230 is fixedly disposed coaxially between the top surface of the hollow structure and the top surface of the handle body 210, and preferably, two ends of the first spring 230 are fixedly connected with the top surface of the hollow structure and the top surface of the handle body 210 through threads or welding respectively. The sleeve 220 is slidably sleeved with a hammer 240, and the hammer 240 can drive the sleeve 220 to axially move along the handle 210 and perform beating and drawing on the intramedullary file 300 under the restoring force of the first spring 230.
The beating and pulling mechanism 200 further comprises an automatic telescopic device, which specifically comprises: a pair of long holes 250 axially provided along the hammer 240 and symmetrically provided on both sides of the hammer 240 in the radial direction, and a stepped hole 260 is provided at the bottom of any one of the long holes 250. A locking pin 270 is radially and slidably arranged at the lower part of the handle body 210, and two ends of the locking pin respectively penetrate through the long holes 250; a first stud 271 is coaxially disposed at one end of the latch 270 and a second stud 272 is coaxially disposed at the other end of the latch 270. A second spring 280 is provided over the latch 270 between the ram 240 and the first head 271. When no external force is applied, the second pin 271 is located in the stepped hole 260, and the hammer body 271 is axially locked along the shank 210, i.e. the hammer body 240 cannot axially move along the shank 210, so that the structure can be kept stable in a natural state. When an external force acts on the first pin head 271, the lock pin 270 moves radially along the handle 210, and drives the second pin head 272 to penetrate out of the stepped hole 260, so as to unlock the hammer 240, so that the hammer 240 can move axially along the handle 210, and the pulling operation is completed. Namely, the beating and pulling operation can be completed without additional operation.
The locking pin 270 has an outer diameter smaller than the width of the slot 250, so that the hammer 240 can move axially along the shank 210 after the hammer 240 is unlocked. The diameter of the first pin 271 is larger than the width of the long hole 250, so as to avoid the first pin 271 from entering the handle 210 and further causing pin removal. The diameter of the second nail head 272 is larger than that of the first nail head 271, and the diameter of the second nail head 272 is smaller than that of the stepped hole 260, so that the second nail head 272 can freely enter the stepped hole 260, and locking and unlocking of the hammer body 240 are realized.
As another embodiment of the present invention, the hammer 240 includes: the connecting cylinder 241 is of a hollow structure and is slidably sleeved on the sleeve 220; end covers 242 are arranged at the two axial ends of the connecting cylinder 241 in a coaxial integrated manner, are of annular structures, and are used for increasing the contact area between the hammer 240 and the main structure 110 of the intramedullary file locking mechanism 100 and improving the beating and pulling effect and the beating and pulling stability.
As another embodiment of the present invention, the sleeve 220 includes: a sleeve 221, which is hollow and is slidably sleeved on the handle 210; a top cover 222 is coaxially and integrally formed at the top of the sleeve 221, and the diameter of the top cover 222 is larger than the inner diameter of the connecting cylinder 221. The hammer 240 can drive the sleeve 220 to move together when moving along the axial direction of the handle 210, and the sleeve 220 can drive the hammer 240 to move when returning under the action of the restoring force of the first spring 230, so as to realize the pulling operation.
The locking 100 mechanism of the intramedullary cavity file comprises: a body structure 110, which is a hollow structure; the locking handle 120 is L-shaped, one end of the short side extends into the upper part of the inner side of the main body 110 and is hinged with the main body 110 through a pin 121, one end of the long side extends out of the main body 110, and the locking handle 120 can rotate close to or far from the handle body 210. A drag hook 130 is provided at the inner lower portion of the main body structure 110, and is hinged with the main body structure 110 through a pin 131 for rotationally locking the intramedullary canal file 300. The spring plate 140 is hinged at its axial ends to the locking handle 120 and the drag hook 130 by pins 141, respectively. When the locking handle 120 rotates to be close to the handle body 210, the head of the drag hook 130 hooks the groove of the intramedullary file 300, and the spring piece 140 is in a bending state and keeps not to rebound, and the elasticity generated by bending of the spring piece 140 ensures that the intramedullary file 300 is in a locking state; when the locking knob 120 is rotated away from the handle body 210, the retractor 130 unlocks the intramedullary canal file 300.
The limiting block 150 is fixedly arranged in the main body structure 110 above one end of the short side of the locking handle 120, when the locking handle 120 rotates to be close to the handle body 210, and one end of the long side of the locking handle is parallel to the handle body 210, one end of the short side of the locking handle contacts with the limiting block 150, so that the over-limit of the rotation of the locking handle 120 is avoided, the service lives of the spring piece 140, the locking handle 120 and the drag hook 130 are shortened, and damage to the intramedullary file 300 is possibly caused by overlarge locking moment to the intramedullary file 300.
The invention relates to a marrow cavity file drawing device which is designed and developed, and is provided with a drawing mechanism, wherein a hammer body drives a sleeve to axially move along a handle body, and the marrow cavity file is drawn under the action of the restoring force of a first spring. Compared with the traditional intramedullary canal rasping and pulling device, the intramedullary canal rasping and pulling device can be used for rapidly disassembling and assembling the intramedullary canal rasp, can also simplify rasping and taking out the intramedullary canal rasp in the intramedullary canal of a human body, does not need a hammer, and prevents medical staff and patients from being injured. The invention is also provided with the lock pin and the second spring (automatic telescopic device), so that the structure can be kept stable in a natural state, and the first nail head can be unlocked by the action of external force during use, so that the hammer body can axially move along the handle body (namely, the beating and pulling operation can be completed without additional operation).
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
