Problems solved by technology

[0004] During the process of implanting the related intervertebral fusion device into the spine, the size of the intervertebral fusion device often needs to be selected through experience, which often leads to the inappropriate size of the intervertebral fusion device and the distance between the two vertebral bodies, and it is not suitable to take it out Replace the intervertebral fusion device with a new intervertebral fusion device, which affects the efficiency and effect of the operation

Embodiment Construction

[0033] The following is attached Figure 1-3 The application is described in further detail.

[0034] The embodiment of the present application discloses a trial model of an expandable intervertebral fusion device. Such as figure 1 As shown, a trial mold of an expandable intervertebral fusion includes a trial mold body 1 and a fixing tube 21 , one end of the fixing tube 21 is fixed with an adjustment platform 2 , and the trial mold body 1 is connected to the adjustment platform 2 .

[0035] The width of the trial model body 1 can be adjusted. Before the cage is implanted, the trial model body 1 is inserted between the vertebral bodies through the fixing tube 21, and the width of the trial model body 1 is adjusted until the trial model body 1 is stuck in the vertebral body. At this time, the width of the trial model body 1 can be used as a reference for the operator to select a fusion cage with an appropriate size, thereby improving the degree of adaptation between the size o...

Abstract

The invention discloses an expandable interbody fusion cage test die, and belongs to the field of interbody surgical instruments. The expandable interbody fusion cage test die comprises a test die body and a fixing tube; an adjusting table is arranged at one end of the fixing tube; an adjusting rod is arranged in the fixing tube in a penetrating manner; the adjusting rod is arranged on the adjusting table in a penetrating manner and is in threaded connection with the adjusting table; the test die body comprises two test die blocks; the test die blocks are slidably connected to the adjusting table; the faces, close to each other, of the two test die blocks are provided with guide faces abutted against the adjusting rod; and the two guide faces are symmetrically arranged and are obliquely arranged from the end close to the adjusting table to the end away from the adjusting table. The expandable interbody fusion cage test die has the effect of improving the adaptation degree of the size of a fusion cage and an interval between two vertebral bodies.

Description

technical field [0001] The invention relates to the field of intervertebral surgical instruments, in particular to an expandable intervertebral fusion device trial model. Background technique [0002] Intervertebral surgery is a common surgical procedure for the treatment of lumbar spine diseases, such as intervertebral disc disease, lumbar instability, etc. These diseases are more common in middle-aged and elderly people, but as the sedentary problem in society becomes more serious, lumbar spine diseases tend to become younger Therefore, the treatment of lumbar diseases becomes particularly critical. [0003] Spinal fusion is a type of intervertebral surgery. Spinal fusion requires the use of an intervertebral fusion device. During the operation, the intervertebral fusion device will be implanted between the vertebral bodies of the spine to maintain the distance between the two vertebral bodies. , to achieve follow-up rehabilitation. [0004] During the process of implant...
