Description

Guiding device in anastomat operation

Technical Field

The utility model relates to the technical field of medical equipment, in particular to guiding device in anastomat art.

Background

In the complete laparoscopic gastrectomy, the anastomosis of the esophagus and the jejunum is a difficult operation. At present, although there are various esophageal jejunum anastomosis modes, the various modes have respective advantages and disadvantages, and no standard mode exists. Although the Overlap anastomosis method is proposed in recent years, the Overlap anastomosis method is better applied at present due to the characteristics of high anastomosis safety, convenience in operation and the like. The Overlap anastomosis method adopts a laparoscope linear anastomat to cut off the esophagus, a small hole is formed in the left side of the cut end of the esophagus, the distal jejunum is lifted, a 12mm Trocar on the left side of an operator is placed into a 60mm linear anastomat, the nail surface is inserted into the jejunum, the non-nail surface is inserted into the small opening of the esophagus, and the esophagus jejunum side anastomosis is performed. However, when the non-nail surface of the linear anastomat is inserted into the esophageal laceration, a 'false cavity' may be inserted, wherein the esophageal wall has 4 layers, namely, a mucosa layer, a submucosa layer, a muscle layer and an adventitia layer, and when the non-nail surface is inserted into the layer surface outside the esophageal mucosa layer, the 'false cavity' is formed, and collapse results can be brought after anastomosis. To reduce the risk of such insertion into a "false lumen," the clinician would use a gastric tube inserted through the mouth to the esophageal stump to guide the stapler into the esophageal mucosa cavity. However, the non-staple shapes of the gastric tube and the anastomat are different in clinic, and the butt joint relation cannot be formed, so that the risk of inserting the 'false cavity' cannot be completely eliminated. This potential "false lumen" risk limits the use of Overlap to some extent.

Referring to fig. 1 to 3, the guiding device for anastomat in operation in the embodiment of the present invention includes a channel member 10 and a guiding component, the channel member 10 is a soft member, optionally, the channel member 10 may be a stomach tube, thereby ensuring that the guiding component can penetrate into the position of the esophagus in vivo and does not damage the esophagus. The guide assembly may allow the soft channel member 10 to be inserted more quickly and easily. The guiding assembly comprises a connecting rod 20 and an openable and closable anastomotic assembly, wherein the connecting rod 20 is movably arranged in the channel member 10 along the axial direction, the anastomotic assembly is fixed at a first end of the connecting rod 20, the anastomotic assembly is in a closed state when being retracted into the channel member 10, and correspondingly, the anastomotic assembly is in an opened state when being extended out of the channel member 10. In use, the connecting rod 20 is pulled, and the connecting rod 20 drives the anastomosis assembly to extend or retract into the channel member 10. Specifically, promote connecting rod 20 and make the subassembly that coincide stretch out passageway component 10, the subassembly that coincide opens, the non-nail face section 51 of anastomat stretches into in the subassembly that coincide, promote connecting rod 20 this moment and can make the subassembly that coincide retract into passageway component 10, the subassembly that coincide simultaneously closes fixes the non-nail face section 51 of anastomat between the subassembly that coincide, with this anastomat intraoperative guiding device wholly stretch into the esophagus in can accurately deliver the non-nail face section 51 of anastomat to the esophagus incision, avoid the anastomat to produce the influence to the human body because of getting into the position beyond the esophagus mucosa layer, prevent the formation of cavity, avoid causing the damage to the human body. In addition, it is generally necessary to place a gastric tube for gastrointestinal decompression after total gastrectomy in clinical practice, and therefore, when the guided anastomosis is completed, the tunnel member 10 can be continuously placed in the digestive tract as a gastric tube for gastrointestinal decompression.

In this embodiment, the anastomosis assembly includes two flexible anastomosis portions 30, a clamping space for clamping the anastomat is formed between the facing surfaces of the two anastomosis portions 30, and the distance between the two anastomosis portions 30 in the opened state is greater than the inner diameter of the channel member 10. Since the two anastomotic portions 30 have elasticity, when the anastomotic assembly is extended out of the channel member 10, the two anastomotic portions 30 are separated from each other by the elasticity to be expanded, and accordingly, when the anastomotic assembly is retracted into the channel member 10, the two anastomotic portions 30 are close to each other by the stopper of the channel member 10 to be closed. Further, the curvature of the outer edge 31 of the anastomosis portion 30 is smaller than the curvature of the inner edge 32 of the anastomosis portion 30, in this application, the outer edge 31 of the anastomosis portion 30 refers to the outer side surfaces of the anastomosis portion 30, which are far away from each other, and similarly, the inner edge 32 of the anastomosis portion 30 refers to the inner side surfaces of the anastomosis portion 30, which are opposite to each other. As the anastomosis member is extended and contracted, the outer edge 31 of the anastomosis portion 30 abuts against the inner wall of the channel member 10, and is easily contracted into the channel member 10 due to the small curvature of the outer edge 31. The radian of the inner side edge 32 of the inosculating part 30 is larger, so that the anastomat non-nail surface section 51 can be wrapped and is in good inosculation contact with the anastomat non-nail surface section 51, the anastomat non-nail surface section 51 is stably fixed, and the guiding effect is good.

The guiding assembly further comprises a pull ring 40, wherein the pull ring 40 is fixed at the second end of the connecting rod 20, and a user can insert fingers into the pull ring 40 when using the guiding assembly, so that the connecting rod 20 is more convenient to drive. Specifically, the connecting rod 20 comprises a rigid first connecting rod 21 and a flexible second connecting rod 22, the end of the first connecting rod 21 and the end of the second connecting rod 22 are connected with each other, the end of the first connecting rod 21 far away from the second connecting rod 22 forms a second end of the connecting rod 20, and the pull ring 40 is fixed on the first connecting rod 21; the end of the second link 22 remote from the first link 21 forms a first end of the connecting rod 20, and the anastomosis assembly is secured to the second link 22. As an alternative embodiment, the first link 21 is integrally formed with the second link 22; as another alternative, the first link 21 is detachable from the second link 22, the first link 21 is short and inflexible, and the second link 22 is elongated and flexible to facilitate its deformation with the tunnel member 10 to adapt to the internal body environment.

Further, the outside of the channel member 10 is provided with a power assisting assembly, which is located outside the second end of the channel member 10. The user is able to better grip channel member 10 by the booster assembly, thereby bringing the guide assembly into motion relative to channel member 10. In particular, the force assist assembly comprises two force assist rings 11, the two force assist rings 11 being symmetrically distributed over the channel member 10. In use, a user may insert a finger into the power ring 11 to fix the position of the channel member 10.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
