Abstract
The utility model relates to a nail anvil assembly with an intracavity pressure-discharging function of a tube type anastomat, belonging to a component of surgical operation equipment. The nail anvil assembly comprises a left clamp spring, a nail anvil cover, a nail anvil, a right clamp spring and a knife anvil that are matched with one another; the nail anvil comprises a nail anvil platform arranged on the upper end surface of a nail anvil pillar; a pressure-discharging flow guiding hole and a clamp spring mounting hole are arranged on the nail anvil platform; a pouch binding groove, a guide positioning rib and a nail anvil clamp holding groove are arranged on the outer wall of the nail anvil pillar; the knife anvil comprises an inner ring and an outer ring, an annular flow guiding groove is formed between the inner ring and the outer ring, a half-round pressure-discharging flow guiding hole is arranged on the inner ring, and an installation positioning boss is arranged on the outer ring. The nail anvil assembly solves the problem that two sealed cavities can not discharge pressure due to overlarge pressure in the two sealed cavities when in the anastomotic state.
Description
Technical field
The utility model relates to a kind of tube type anastomat nail-anvil assembly, be the surgical operating instrument parts, be applicable to end-end, end to side and the side-side-to-side anastomosis operation in the operation on digestive tract such as esophagus, stomach, intestinal with intracavity row pressure function.
Background technology
Nail-anvil assembly is as the parts of tube type anastomat, has the colligation pocket, the location is installed, the molding of anastomosis staple guiding, cutting knife cuts off tissue that effects such as pad cutter chopping block are provided.
Existing anastomat is design intracavity row pressure device on nail-anvil assembly not; Or only nail anvil lid, and nail anvil on design the hole of leading off is arranged, this structural design is very unreasonable.Because of the cutter anvil provides pad cutter chopping block for cutting knife cuts off tissue, as the indispensable part of nail-anvil assembly, it is annular monolateral sealing, and design has the hole of leading off on the nail anvil so only cover, reach at nail anvil, lead the hole site off and all blocked, so act on not satisfactory by the monolateral sealing of cutter anvil annular.In operation process, tube type anastomat passes an end digestive tract lumen organization, closure is tightened up the other end digestive tract lumen organization that is fixed on the nail-anvil assembly, speed is fast, and this moment, two ends, anastomosis sealed tube cavity pressure can't discharge, and caused the anastomotic stoma instantaneous pressure too high, bring that tissue is congested, anastomosis staple pressurized aftershaping is bad, the anastomotic stoma oozing of blood, What is more or cause the risk of anastomotic leakage, brings misery to sufferer.
Summary of the invention
This utility model provides a kind of tube type anastomat nail-anvil assembly with intracavity row pressure function, this nail-anvil assembly is applicable to the tube type anastomat that end-end, end to side and side-the side-to-side anastomosis operation is used in the operation on digestive tract such as esophagus, stomach, intestinal, it is excessive to have solved when identical two enclosed cavity internal pressures, problem that can't row pressure.
For achieving the above object, the technical scheme that this utility model adopted is:
A kind of tube type anastomat nail-anvil assembly with intracavity row pressure function, comprise the left jump ring, nail anvil lid, nail anvil, right jump ring, the cutter anvil that cooperatively interact and be provided with, described nail anvil comprises the nail anvil platform that is arranged on nail anvil post upper surface, the nail anvil platform is provided with row pressure pod apertures, jump ring installing hole, and the outer wall of nail anvil post is provided with pocket colligation groove, guide-localization muscle, nail anvil pincers and adds and hold groove; The cutter anvil comprises internal ring and outer shroud, forms an annular diversion trench between internal ring, the outer shroud, offers row pressure drain semicircle orifice on the internal ring, offers the installation positioning boss on the outer shroud.
Described nail anvil covers and is provided with row pressure release aperture and stitching thread fixed cross beam.
The diameter of described row pressure pod apertures is 2.5 ~ 4mm, and shape can be for cylindrical or square.
Described row pressure pod apertures is provided with 4 ~ 6.
The diameter of described row pressure release aperture is 2.5 ~ 4mm, and shape can be for cylindrical or square.
Described row pressure release aperture is provided with 4 ~ 6.
Described guide-localization muscle is provided with 4 ~ 8, and row pressure drain semicircle orifice is provided with 2 ~ 6, positioning boss is installed is provided with 3 ~ 6.
This utility model has evenly been got rid of the too high instantaneous pressure of intracavity anastomotic stoma, avoids that tissue is congested, anastomosis staple pressurized aftershaping is bad, has solved the anastomotic stoma oozing of blood, and the risk of anastomotic leakage brings glad tidings to sufferer.The hematocele, the hydrops that produce in the time of also can coincideing to tube chamber produce the effect that drain is got rid of.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the overall decomposing schematic representation of this utility model preferred embodiment.
The specific embodiment
As shown in Figure 1, the utlity model has the tube type anastomat nail-anvil assembly of intracavity row pressure function, the left jump ring 1 that comprising cooperatively interacts is provided with, nail anvil lid 2, nail anvil 3, right jump ring 4, cutter anvil 5.
Nail anvil 3 comprises the nail anvil platform 36 that is arranged on nail anvil post 37 upper surfaces, and nail anvil platform 36 is provided with row pressure pod apertures 32, jump ring installing hole 31, and the outer wall of nail anvil post 37 is provided with pocket colligation groove 33, guide-localization muscle 34, nail anvil pincers and adds and hold groove 35.The diameter of row pressure pod apertures 32 is 2.5 ~ 4mm, and shape can be for cylindrical or square.Row pressure pod apertures 32 is provided with 4 ~ 6.Guide-localization muscle 34 is provided with 4 ~ 8.
