The oval operation channel made of metal is originally created in the application, is mainly used for exposing the spine spinal cord minimally invasive channel operation, and can also be used for incision minimally invasive requirements of other surgical operations.
Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a oval minimal access surgery passageway is related to.
Background
At present, several times of plastic oval channels at home and abroad in the market are suitable for minimally invasive operations of brain and soft organs, and need sharp incisions of blades, so that dilators cannot be applied. In minimally invasive spine surgery, after a hole is cut in a human body, soft tissues at the cut hole need to be expanded, and after the soft tissues are expanded, a minimally invasive surgery space is formed so that surgical instruments (such as an endoscope and the like) can extend into an affected part from the cut hole to perform surgery. At present, after the cut hole is expanded, a cylindrical channel tube is inserted and the cut hole is kept expanded to form an operation space (the expansion mode can adopt expansion tubes from thin to thick to expand step by step, then the cylindrical channel tube is inserted into the cut hole, and each expansion tube is taken out). However, the cylindrical channel tube has small caliber and is in a straight cylinder shape, so that the operation field and space are small, and observation and operation are inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an oval minimal access surgery passageway.
To achieve the above object, the present invention adopts the following:
an elliptical minimally invasive surgical tunnel comprising: an outer sleeve, an expansion converter and an expander; an expansion converter is sleeved outside the expander, and the length of the expansion converter is smaller than that of the expander; an outer sleeve is sleeved outside the expansion converter; the cross section of the outer sleeve is oval, and the tail end of the outer sleeve is provided with an annular step; the annular step is provided with a connecting handle.
Preferably, the cross section of the outer sleeve is golden oval.
Preferably, the annular step is connected with the outer sleeve in a smooth transition mode.
Preferably, the connecting handle is fixedly connected with the annular step.
Preferably, the connecting handle is a metal handle and is connected with an external operating arm.
Preferably, the outer sleeve is made of metal.
The utility model has the advantages of it is following:
the oval operation channel made of metal is originally created in the application, is mainly used for exposing the spine spinal cord minimally invasive channel operation, and can also be used for incision minimally invasive requirements of other surgical operations. Compared with the existing circular surgical path, the oval channel can realize minimally invasive double-hand mechanical operation to the maximum extent; the incision is smaller; less injury and cutting of human tissue fibers such as muscle ligaments and the like are caused; the tissue is more naturally stretched and expanded, and is not easy to be ischemic and blackened and necrotic; can also meet the requirement of reasonably extending the surgical field in the operation. The ellipse is designed by adopting the golden ellipse equation, so that the structure characteristics of human muscle and tissue fiber are naturally and more smoothly carried out.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the oval minimally invasive surgery passage structure of the present invention.
FIG. 2 is a schematic view of the separation structure of the oval minimally invasive surgery channel of the present invention
In the figures, the various reference numbers are:
1-outer sleeve, 2-expansion converter, 3-expander and 4-connecting handle.
Detailed Description
In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 2, an elliptical minimally invasive surgical tunnel comprises: an outer sleeve 1, an expansion converter 2 and an expander 3; the expander 3 is sleeved with an expansion converter 2, and the length of the expansion converter 2 is smaller than that of the expander 3;
it should be noted that the dilator 3 of the present application is a cylindrical dilator commonly used in the prior art, and the front end of the dilator is circular, and the opened surgical field is also circular. The expansion converter 2 is a transitional pipe, and the length of the expansion converter 2 is smaller than that of the expander 3 and larger than that of the outer sleeve 1. The inner wall of the expansion converter 2 is circular, is matched with the expander 3 and can slide mutually, and the outer wall of the expansion converter 2 is elliptical and is used for matching with the outer sleeve 1.
The outer sleeve 1 is sleeved outside the expansion converter 2; the cross section of the outer sleeve 1 is golden oval, and the tail end of the outer sleeve 1 is provided with an annular step; the annular step is connected with the outer sleeve 1 in a smooth transition way. The annular step is provided with a connecting handle 4. The connecting handle 4 is a metal handle and is connected with an external operating arm, and the outer sleeve is made of metal.
The working principle of the device is as follows: when in use, the universal round dilator 3 is sleeved with the oval round dilating converter 2, and then sleeved with the oval outer sleeve 1 with the fixed handle, and the round dilator and the oval dilator are drawn out after the handle is fixed, thereby completing the exposure of the oval surgical field.
Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
