Description

Vertebral plate forceps

Technical Field

The application relates to a medical instrument, in particular to a vertebral plate clamp.

Background

In the prior art, cervical laminoplasty can effectively treat severe cervical spondylosis such as cervical spinal stenosis, cervical posterior longitudinal ligament calcification, multi-stage myelogenous cervical spondylosis, yellow ligament hypertrophy or calcification. In the single-door laminoplasty, a vertebral plate on one side is completely cut off, a groove is cut off from the vertebral plate on the opposite side, and the vertebral plate is lifted by taking the groove as a hinge, so that the aims of expanding a vertebral canal and decompressing the spinal cord are fulfilled. However, the depth of the cut in the portal shaft recess has been a troublesome problem, and cutting too deep in the recess can cause the lamina to break during the process of lifting the lamina. The recess is cut too shallow to effectively lift the lamina.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a vertebral plate pincers, includes the first pincers body and the second pincers body of interconnect, the first pincers body comprises first binding clip and first pincers handle, the second pincers body comprises second binding clip and second pincers handle, the inside cavity of first pincers handle, inside the first pincers handle was located to second pincers handle cover, the inside reset spring that is provided with of first pincers handle, reset spring supports and holds second pincers handle afterbody, rectangular shape through-hole has been seted up to first pincers handle front end, the second pincers handle is formed with the second handle along rectangular shape through-hole outside extension, the second handle drives the second pincers handle is in the inside reciprocating motion of first pincers handle.

Preferably, the first forceps body further comprises a first handle, and the first handle is vertically arranged at the tail of the first forceps handle.

Preferably, the second handle is connected with the second forceps handle through threads, and a holding part is arranged on the surface of the second handle.

Preferably, the front end of the second tong head is provided with a hooking part.

Preferably, the first binding clip is arc-shaped.

Compared with the prior art, the vertebral plate forceps control the cutting depth of the groove at the cervical vertebra portal axis through the two forceps bodies which can move relatively.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a cross-sectional view of a vertebral plate forceps in accordance with an embodiment of the present invention;

FIG. 2 is a schematic view of a vertebral plate forceps according to an embodiment of the present invention

FIG. 3 is a schematic view of a vertebral plate of the vertebral plate forceps before the vertebral plate is lifted according to an embodiment of the present invention;

fig. 4 is a schematic view of the vertebral plate forceps after the vertebral plate is lifted according to the embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Combine shown in figure 1, the vertebral plate pincers of this application, including interconnect's the first pincers body 3 and the second pincers body 4, the first pincers body 3 comprises first binding clip and first pincers handle, the second pincers body 4 comprises second binding clip and second pincers handle, the inside cavity of first pincers handle 3, inside the first pincers handle was located to the second pincers handle cover, first pincers handle is inside to be provided with reset spring 5, reset spring supports and holds second pincers handle afterbody, rectangular shape through-hole has been seted up to first pincers handle front end, the second pincers handle is formed with second handle 2 along rectangular shape through-hole outwards extends, the second handle drives the second pincers handle is in the inside reciprocating motion of first pincers handle.

In this technical scheme, through the mode of establishing, with the first pincers body 3 and the second pincers body 4 organic combination, the second handle 2 is fixed in the first pincers body 3 with the rectangular shape through-hole with the second pincers body 4, and reset spring 5 promotes the second pincers body 4 all the time simultaneously, drives the second pincers body 4 at the first pincers body 3 reciprocating motion through the second handle 2.

Preferably, the first forceps body 3 further includes a first handle 1, and the first handle 1 is vertically disposed at a tail portion of the first forceps handle.

In the technical scheme, the first handle 1 is arranged at the tail end of the first forceps body 3, so that the first forceps body 3 can be held conveniently during an operation.

Preferably, the second handle 2 is connected with the second forceps handle through threads, and a gripping part is arranged on the surface of the second handle 2.

In the technical scheme, the second handle 2 is detachably connected with the second forceps body 4, so that the second forceps body is convenient to detach and install, and the holding part of the second handle 2 is convenient for performing an operation.

Preferably, the first binding clip is arc-shaped.

Compared with the prior art, the vertebral plate forceps control the cutting depth of the groove at the cervical vertebra portal axis through the two forceps bodies capable of moving relatively.

Referring to fig. 2-3, in a specific use process, the first handle 1 and the second handle 2 are held by hands, the second handle 2 is lifted to control the second clamp body 4 to hook the vertebral plate and lift the vertebral plate upwards, the second clamp body 4 slides in the first clamp body 3 and touches a return spring 5 built in the first clamp body 3, and the return spring 5 has a reaction force on the first clamp body 3, so that whether the notch on the side of the door shaft is cut in place is judged. If the force felt is too great, the groove needs to be cut deeper. If the force is moderate, the lamina will continue to be pulled until the surgical requirements are met.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
