Description

Small incision operation expander

Technical Field

The utility model belongs to the technical field of medical instrument, specifically speaking relates to a little incision operation expander.

Background

The expander is used for strutting the operation incision and is convenient for the doctor to carry out the operation, because the fat thickness of different patient's health is all different, and the body length of expander needs the thickness of more than or equal to patient's fat, so the expander has different bores and high specification, but the expander of chooseing for use in the operation use also can be with the tension of incision card sometimes.

SUMMERY OF THE UTILITY MODEL

In view of this, the technical problem to be solved of the present invention is to provide a small incision surgical dilator, which solves the problem of over-tightening of the dilator and the incision clip in the prior art.

In order to solve the technical problem, the utility model discloses a little incision operation expander, include: a dilator body; the expander body is provided with a pipe body, a first expanding ring and a second expanding ring which are arranged at two ends of the pipe body, a first connecting part for connecting the pipe body and the first expanding ring, and a second connecting part for connecting the pipe body and the second expanding ring; an annular groove is formed at the joint of the first connecting part and the pipe body; the first connecting part is bent; the second connecting part forms an included angle with the pipe body.

Further, the section of the annular groove is circular arc.

Furthermore, the first bending part of the first connecting part is parallel to the end face of the pipe body, and the second bending part of the first connecting part forms an included angle with the pipe body.

Furthermore, the second connecting part and the pipe body form an included angle of 105 degrees.

Furthermore, the second bending part and the tube body form an included angle of 140 °.

Compared with the prior art, the application can obtain the following technical effects:

the utility model discloses a junction of first connecting portion and body is equipped with the ring channel, and both have the function of buckling, and the second kink of first connecting portion is upwards buckled, can realize increasing the length of second kink on the basis of original body height, makes the expander have the changeable body height of elasticity, solves the problem of the tension of expander and incision card.

Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1 and 2, fig. 1 is a schematic view of a normal expander according to an embodiment of the present invention; fig. 2 is a schematic view of the dilator according to an embodiment of the present invention being expanded. A small incision surgical dilator comprising: a dilator body 1; the expander body 1 is provided with a pipe body 2, a first expanding ring 3 and a second expanding ring 4 which are arranged at two ends of the pipe body 2, a first connecting part 5 for connecting the pipe body 2 and the first expanding ring 3, and a second connecting part 6 for connecting the pipe body 2 and the second expanding ring 4; an annular groove 7 is arranged at the joint of the first connecting part 5 and the pipe body 2; the first connecting part 5 is bent; the second connecting portion 6 forms an included angle with the tube body 2.

The section of the annular groove 7 is arc-shaped; the first bent part 8 of the first connecting part 5 is parallel to the end face of the tube body 2, and the second bent part 9 of the first connecting part 5 forms an included angle with the tube body 2; the second connecting portion 6 forms an angle a of 105 ° with the tubular body 2. The second bending portion 9 forms an included angle B of 140 ° with the tube 2.

Inside stuffing the incision with the second expansion ring 4 of expander, the body 2 of expander struts the incision, patient's incision inside and outside play spacing effect is cliied with second expansion ring 4 to first expansion ring 3, when the expander card of electing uses is tight, the second kink 9 of first connecting portion 5 is propped open by incision department tissue and is upwards buckled, can increase the length of second kink 9 on the basis of original body 2 height, thereby the degree that makes the expander card establish is by tight becoming loose.

The utility model discloses a first connecting portion 5 is equipped with ring channel 7 with the junction of body 2, and both conveniently have the function of buckling, and the second kink 9 of first connecting portion 5 is upwards buckled, can realize increasing the length of second kink 9 on the basis of original body 2 height, makes the expander have flexible changeable body height, solves the problem of the tension of expander and incision card.
