Description

Auxiliary traction device under endoscope

Technical Field

The utility model relates to the field of medical equipment, concretely relates to supplementary draw gear under scope.

Background

Currently, endoscopic mucosal dissection has become a widely accepted gastrointestinal early cancer minimally invasive surgery type, and is limited to the steep learning curve and requires a long time for large-scale clinical application. Therefore, auxiliary traction technologies related to endoscopic mucosal dissection which simplify the operation process are developed, and the auxiliary traction technologies comprise a metal wire clamping and wire combining traction technology, a metal clamping and elastic ring combining traction technology, an S-O metal clamping traction technology, a magnetic anchor traction technology, a clamp traction technology, a robot traction technology and the like, wherein the technologies can improve the operation visual field, increase the operation safety and improve the working efficiency.

However, there are often problems to be solved in the specific use of the above technology.

For example, the S-O metal clip traction technology has the defects that the length is fixed, different lengths are needed for different positions in a gastrointestinal cavity, the traction cannot be realized when the space is too small, and the traction cannot be realized when the space is too large; and need cut the nylon circle after finishing using, need special under-the-mirror ware of cutting, not only waste time, the scope center of most hospital does not have the device moreover, consequently promotes difficultly.

In the combined traction technology such as a metal clip elastic ring, the following defects exist in the use process:

1. the size of the lesion needs to be similar to that of an elastic ring, the application range is severely limited, the lesion with the size exceeding 1.0cm cannot be used, and the main indication of ESD is the lesion with the size exceeding 2.0 cm.

2. In the stripping process, the affected part needs to be pre-cut before use, and has limitation to some difficult and special cases.

3. The operation is difficult, because the horizontal direction pulls, and the exposure field of vision is limited, and for the fragile tissue of edge, too much clamping is easy to destroy the sample.

Although the chinese patent with application number 201910117258.2 discloses a multicycle tractor under scope and its application method can effectively solve the above-mentioned metal wire clamping line and unite the traction technique, the metal clip elastic ring unites the traction technique, the S-O metal clip traction technique, the magnetic force anchor traction technique, the many problems that exist in concrete use such as pincers traction technique and robot traction technique, however, this multicycle tractor under scope operates more complicatedly in the use, the risk is high, the operation is wasted time and energy, and the medical skill requirement to the doctor of the main knife is high, very be unfavorable for using widely in vast middle and small-size hospital, based on this, design the utility model discloses a design.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an supplementary draw gear under scope just for solving above-mentioned problem to solve among the prior art under the scope multi-ring tractor and operate complicacy when using, the operation risk is high, and the operation is consuming time longer, and the operation level requirement to the doctor is higher, is unfavorable for using widely the scheduling problem. The utility model provides an among a great deal of technical scheme preferred technical scheme can realize under simple and convenient operation scope multi-ring tractor, greatly reduced operation risk, the operation weak point consuming time, it is not high to require doctor's operation level, uses at vast middle-size and small-size hospital push rod easily, technical effect such as the practicality is good, sees the explanation below in detail.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a pair of supplementary draw gear under scope, including a plurality of elastic rings, a plurality of elastic rings are in proper order worn to connect together and are formed a traction chain.

Has the advantages that: supplementary draw gear under scope easy operation convenience when using, it is not high to require doctor's operation level, effectively reduces the operation risk, shortens the operation time, labour saving and time saving is fit for using widely in vast middle-size and small-size hospital, the practicality is good.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and 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.

Referring to fig. 1-3, the utility model provides an auxiliary traction device under endoscope, including a plurality of elastic rings 1, a plurality of elastic rings 1 are worn to connect together in proper order and form a traction chain, so the design, compare the connected mode that relies on the connecting wire to connect two elastic rings 1 more firm, and under the condition that total length is certain, the auxiliary traction device under endoscope of the utility model sets up elastic rings 1 more, corresponding flexible volume is bigger, can draw longer, and need not to support fixedly with the help of parts such as arc piece, base, support column, opener, directly press from both sides tightly with titanium clamp 2 and put into the tong way can, save time and labor, easy operation, and not high to doctor's operation level requirement, effectively reduce the operation risk, shorten the operation time, save time and labor, be suitable for popularization and use in vast middle-size and small-size hospitals, the practicality is good, and the scope lower multi-ring tractor disclosed in the chinese patent with application number 201910117258.2 then need just can fix a plurality of elastic ring 1 with the help of the arc piece, a pedestal, the support column, open the ware, the operation is very troublesome and waste time and energy, and be subject to blocking of arc piece in the pincers way, press from both sides elastic ring 1 and press from both sides the operation that needs doctor's careful wing on fixing focus tumor piece 4, slowly separate two arc pieces, this undoubtedly needs the doctor to have extremely strong working ability, it is long consuming time, the danger coefficient is high, unsuitable the quick study of the doctor of most of middle-size and small-size hospitals is mastered.

When the auxiliary traction device under the endoscope is used, a traction chain is clamped and pushed into a clamping channel by a titanium clamp 2, then an elastic ring 1 at one end of the traction chain is fixed on a focus tumor block 4 through the titanium clamp 2, then the elastic ring 1 at the other end of the traction chain is fixed on a stomach wall or an intestinal wall 3 opposite to a focus through another titanium clamp 2, and then the tumor block 4 can be peeled; in the stripping process, elastic rings 1 at two ends of a traction chain are fixed at different positions through titanium clips 2, so that the traction chain is pulled to form traction force, and the lesion tumor mass 4 is stripped under the action of the traction elastic force; when the original traction force is weakened, the elastic ring 1 opposite to the focus is changed again, or another elastic ring 1 is fixed again through the titanium clip 2 on the opposite side of the lesion, the working length of the traction chain is shortened, the traction force among the 2 titanium clips 2 is enhanced, the process is circulated until the tumor mass 4 of the focus is completely stripped, and after the tumor mass 4 is stripped, the foreign body forceps or the snare is used for pulling out the titanium clip 2 fixed on the mucosa on the opposite side, so that the specimen can be taken out.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
