Abstract
An ultrasonic tool used for surgery comprises a treatment part, a sheath body, a probe and a handpiece, wherein the probe is provided with two bending parts, namely a first bending part and a second bending part; therefore, the probe is divided into three parts: a near-end part, a middle part and a far-end part. Compared with the prior art, the ultrasonic tool overcomes the defects of difficult operation and insufficient accuracy of the ultrasonic tool in the prior art through the design of structural optimization, the coordination performance of force and direction of the ultrasonic tool is improved, the operator is ensured to use the ultrasonic tool more accurately in the surgery, and the safety of the surgery is improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of operation ultrasonic tool that is applied in the surgery medical operating.
Background technology
Operation is an a kind of common aid in the medical apparatus and instruments with ultrasonic tool, is used for the tissue in operation treatment patient's damage or pathological changes.Provided applied a kind of ultrasonic tool in the prior art in the accompanying drawing 3, this ultrasonic tool 100 is made up of four parts: treatment portion 101, sheath body 102, probe 103 and head 106; Wherein probe segment 103 has a kink, thereby this probe segment 103 comprises two parts, and a part is to be the close end of axis with central shaft O1, and a part is to be the distal portion of axis with central shaft O2.Because this operation all is to have only a bending place with the probe of ultrasonic tool, there are some defectives in operation in the ultrasonic tool of this spline structure, because head occupies heavier component, and probe is low weight, thereby in actual applications, the point that is unfavorable for the tissue that operator's accurate in locating need be handled, thus the safety of performing the operation reduced, and also incured loss through delay surgery duration.
Summary of the invention
The purpose of this utility model is to provide a kind of operation ultrasonic tool, by Optimal Structure Designing, overcome existing not easy to operate, the defective that accuracy is not enough of the ultrasonic tool of prior art, improve the operating characteristics of ultrasonic tool, be beneficial to the operator and in operation, use more accurately, improve the safety of operation.
For achieving the above object, the utility model discloses a kind of operation ultrasonic tool, it comprises: treatment portion, sheath body, probe and head.Wherein, probe has two kinks: first kink and second kink, thus probe has been divided into three parts: proximal part, mid portion, distal portions.Proximal part is the axis of symmetry with first central shaft, and mid portion is the axis of symmetry with second central shaft, and distal portions is the axis of symmetry with the 3rd central shaft.Place the intravital probe of sheath extending to by treatment portion on the direction of head, begin to enlarge, regain cone angle, remain cylindrical inner diameter in the position of secondary nodal point with certain cone angle at the position of primary nodal point internal diameter.All on distal portions, wherein the distance between primary nodal point and the kink is first distance for the primary nodal point and first kink; On first kink and secondary nodal point all mediated partly, wherein the distance between first kink and the secondary nodal point was a second distance; Second distance less than or much smaller than first distance.
With prior art relatively, the utility model has the advantages that probe is improved to possess a kink and improve in order to possess two kinks by original, thereby make the operator in use, improve the harmony of power and direction, improved the safety of operation.
Description of drawings
Fig. 1 is the structural representation of the designed operation of this utility model with ultrasonic tool.
Fig. 2 is the operation of the present utility model application sketch map of ultrasonic tool in practical operation.
Fig. 3 is the structural representation of operation of the prior art with ultrasonic tool.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is the ultrasonic tool after this utility model improves.Ultrasonic tool after the improvement also is made up of four parts: treatment portion 1, sheath body 2, probe 3 and head 6.Wherein, probe 3 has two kinks: first kink 7 and second kink 8, thus probe has been divided into three parts: proximal part 3a, mid portion 3b, distal portions 3c.Proximal part 3a is the axis of symmetry with central shaft O1, and mid portion 3b is the axis of symmetry with central shaft O2, and distal portions 3c is the axis of symmetry with central shaft O3.Place the probe 3 in the sheath body 2 extending to by treatment portion 1 on the direction of head 6, begin to enlarge, regain cone angle, remain cylindrical inner diameter in the position of secondary nodal point 11 with certain cone angle at the position of primary nodal point 4 internal diameter.All on distal portions 3c, wherein the distance between the primary nodal point 4 and first kink 8 is b for the primary nodal point 4 and first kink 8; First kink 8 and secondary nodal point 11 all mediate on the part 3b, and wherein the distance between first kink 8 and the secondary nodal point 11 is a; A＜b, perhaps a＜＜b (being the length of the length of a) much smaller than b.
Fig. 2 is the operation of the present utility model application sketch map of ultrasonic tool in practical operation.When patient was undergone surgery, under the observation of microscope 14, operator's hand-held ultrasound instrument was treated the lesion 13 of patient's operative region 16.
