Description

A kind of spinal operation with angular surveying disk is clamped with curved rod

Technical field

It the utility model is related to a kind of spinal operation with angular surveying disk to be clamped with curved rod, belong to medical device technology neck Domain.

Background technology

In spine corrective operation, operative doctor needs to be made by oneself according to the actual conditions of patient's osteotomy site backbone specific curved The titanium alloy bar of bent angle, but clinically common curved rod pincers measure function without angle of bend at present, it is therefore desirable to cure Titanium alloy bar after bending is removed survey by raw must be repeated continuously during the bending of titanium alloy hold-down bars from curved rod pincers Measuring angle carries out curved tedious steps again.Even the doctor with clinical experience for many years when in face of this problem according to It cannot so accomplish once to bend success, so not only extend the time of operation, and repeated multiple times be bent with pliers Titanium alloy bar will also result in certain influence to the physical property of itself, so that the treatment and recovery band to patient carry out bad shadow Ring.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, so as to provide a kind of with angular surveying disk Spinal operation is clamped with curved rod.

A kind of spinal operation with angular surveying disk is clamped with curved rod, is connected with each other by handle A and handle B by fixed column A, Handle A is equipped with fixed column B, and handle B is equipped with fixed column C；The center of the fixed column A is equipped with middle duct, middle duct Inverted L shape pointer is inside equipped with, inverted L shape pointer one end is arranged on handle B；The fixed column A tops of the handle A are equipped with angle scale.

It is using the beneficial effect of above-mentioned technical proposal：

The utility model adds a compact rotational energy adjusting inverted L shape at the twisting position of Liang Ge handles intersection and refers to Pin and dial realize the function of display titanium alloy bar angle of bend, and the curved rod pincers of the utility model are not change doctor original The measurement function of titanium alloy bar angle of bend is added on the basis of use habit, bending for titanium alloy bar and angular surveying is same When complete, can greatly save doctor and spend in the time bent on titanium alloy bar in surgical procedure, shorten surgical procedure, Ensure patient health.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

A kind of spinal operation with angular surveying disk is clamped with curved rod, as shown in the figure：It is passed through solid by handle A1 and handle B2 Fixed column A3 is connected with each other, and handle A1 is equipped with fixed column B4, and handle B2 is equipped with fixed column C5；The center of the fixed column A3 is set There is middle duct 6, inverted L shape pointer 7 is equipped with middle duct 6,7 one end of inverted L shape pointer is arranged on handle B2；The handle The fixed column A3 tops of A1 are equipped with angle scale 8.

The innovation of the utility model is that it is on the top of the fixed column A3 of intersection's projection of two handle twistings There is provided one 360 degree of dial, represents 1 degree with every lattice, which is directly fixed on the part where handle A1；It is located at Adjustable pointer above dial is then at the twisting where being directly fixed on handle B2 through the middle duct 6 of fixed column A3 On part, since inverted L shape pointer 7 can rotate, it is possible to suitable for titanium alloy bar original state to have possessed any angle Or the situation that rod body thickness is inconsistent.When use, between titanium alloy bar is placed on three fixed columns, two are gently pinched Handle, which is depressed into, feels fixed column A3, fixed column B4 and fixed column C5 by the position of titanium alloy bar clamping, then stir through The adjustable inverted L shape pointer 7 of fixed column A3, makes its tip align with any graduation mark, and then firmly clutching handle can bend Titanium alloy bar, and the scale that adjustable pointer streaks is curved angle.

When operation, doctor is first by titanium alloy bar traverse between fixed column A3, fixed column B4 and fixed column C5, so Two handles are gently pinched afterwards, are somewhat firmly depressed into and are felt fixed column A3, fixed column B4 and fixed column C5 by titanium alloy bar The position of clamping.Since the titanium alloy bar to be bent is not necessarily all straight, at the same time, it is contemplated that the thickness of titanium alloy bar may Different situations, at this time, in the case of not release handle, carefully stirs the adjustable inverted L shape pointer through fixed column A3 7, its tip is alignd with any graduation mark, then firmly clutching handle is bent, and adjustable inverted L shape pointer 7 turns over Scale be curved angle.Doctor can judge whether titanium alloy bar reaches that bend will by observing the rotation situation of pointer Ask.
