According to the type of tearable structure, the applicant has devised the following two embodiments:
example 1
The easy-tearing structure is an easy-tearing hole 13 positioned at the junction of the inosculating part 11 and the fixing part 12. The tearing degree of the easy-to-tear hole 13 can be determined according to the perforation density and the perforation shape of the easy-to-tear hole 13.
Example 2
The anastomosis portion 11 and the fixed portion 12 are separated from each other, an easy-tearing material 14 is arranged at the intersection of the anastomosis portion 11 and the fixed portion 12, and the easy-tearing material 14 is connected with the anastomosis portion 11 and the fixed portion 12 respectively. The easily torn material 14 is made of gelatin sponge, and other absorbable porous easily torn materials can be adopted.
When designing the easy-tearing structure, the easy-tearing structure is considered from two design points, firstly, from the structural angle, and the easy-tearing is realized by changing the structure at the junction of the inosculating part 11 and the fixing part 12; from the material perspective, the anastomosis portion 11 and the fixing portion 12 are separated from each other, and then are connected to form a whole through the easily-torn material 14, so that the easily-torn material 14 is arranged at the junction between the anastomosis portion and the fixing portion, and the forced separation can be achieved.
The material of the support pad is one of PLA, PGA, and the polymer of PLA and PGA. Other medical grade degradable materials may also be employed.
The invention discloses an anastomat which is provided with the anastomotic stoma supporting gasket.
The anastomat can be an endoscope cutting anastomat, a circular anastomat, a linear cutting anastomat or a linear anastomat and other conventional anastomats.
Taking the endoscope cutting anastomat 2 as an example, an anastomosis port supporting gasket 1 is arranged on an anastomosis structure of the endoscope cutting anastomat 2. The anastomotic stoma supporting gasket 1 can be installed on the anastomotic structure of the endoscopic cutting stapler 2 before operation, and can also be directly installed when the endoscopic cutting stapler 2 is produced; generally, for the convenience of the operation, the stoma support gasket is preassembled on the endoscopic cutting stapler 2.
The anastomosis structure of the endoscopic cutting stapler 2 mainly refers to a jaw structure at the front end of the endoscopic cutting stapler 2, the upper part of the jaw structure is a nail pushing seat assembly 21, the lower part is a nail bin assembly 22, and the nail bin assembly 22 generally comprises a nail bin 221 and a stainless steel protective layer 222 coated on the outer side of the nail bin 221. The nail abutting seat assembly 21 and the nail bin assembly 22 are both provided with anastomotic stoma supporting gaskets 1. According to the connection mode between the anastomotic orifice supporting gasket and the endoscopic cutting stapler 2, the following embodiments can be derived:
example 3
As shown in fig. 4-6: nail holes are additionally formed in two side faces of a nail bin assembly 22 of the endoscope cutting anastomat 2, fixing portions 12 of anastomotic stoma supporting gaskets are arranged on two side faces of the nail bin assembly 22, the fixing portions 12 are pressed on the side faces of the nail bin through straight strip-shaped pressing sheets 23, and then the straight strip-shaped pressing sheets 23 are locked in the nail holes in the two side faces of the nail bin through rivets 24. Similarly, the nail seat component 21 is also designed in the same way.
As shown in fig. 7-9: the use mode of the endoscope cutting anastomat is the same as that of the existing endoscope cutting anastomat, and the final anastomosis effect is shown in figure 10.
Example 4
The fixing part 12 of the anastomotic stoma support gasket can be directly fixed on the two side surfaces of the nail bin assembly 22 of the endoscopic cutting anastomat 2 through a nontoxic medical adhesive. Similarly, the nail seat assembly 21 may also be designed identically.
Example 5
As shown in fig. 11 and 12: the magazine assembly 22 generally includes a magazine 221 and a stainless steel protective layer 222 covering the outside of the magazine 221. When the nail bin 221 can be processed, the supporting pad for the anastomotic orifice is directly attached, and the fixing part 12 of the supporting pad for the anastomotic orifice can be directly fixed on the side surface of the nail bin 221 through the stainless steel protective layer 222 (that is, the fixing part 12 is clamped between the nail bin 221 and the stainless steel protective layer 222). Because the nail abutting seat assembly 21 does not have a stainless steel protective layer, fixing pieces 211 are added on two sides of the nail abutting seat assembly, the fixing pieces 211 are fixedly connected with the nail abutting seat assembly 21 in a welding mode, and the fixing portion 12 of the anastomotic stoma support gasket 1 is clamped between the fixing pieces 211 and the nail abutting seat assembly 21.
Example 6
As shown in fig. 13-15: the fixing parts 12 of the anastomotic stoma support gasket 1 are arranged on two side surfaces of the nail cartridge assembly 22, and the fixing parts 12 on the two side surfaces of the nail cartridge assembly 22 are connected through a plurality of absorbable surgical sutures 25; the absorbable surgical suture 25 is wound around the outer side surface of the cartridge component 22, and two ends of the absorbable surgical suture 25 are connected with the fixing parts 12 on two side surfaces of the cartridge component 22. Similarly, the nail seat component 21 is also designed in the same way. It should be noted that, after the anastomosis portion 11 is anastomosed, the fixing portion 12 and the absorbable surgical suture 25 lose their support and fall off to the human body to cause contamination. To eliminate the above risks, absorbable surgical sutures 25 are used here.
Example 7
As shown in fig. 16-17: on the basis of embodiment 6, the fixing portion 12 covers both side surfaces of the cartridge assembly 22 and the outer side surface of the cartridge assembly 22, so that the anastomotic stoma support spacer 1 forms a sleeve structure. Similarly, the nail seat component 21 is also designed in the same way.
Example 8
As shown in fig. 18-20: the nail abutting seat assembly 21 of the traditional endoscopic cutting anastomat 2 is generally provided with a section of non-anastomosis area A26 at the head and the tail sides respectively, and the nail bin assembly 22 is generally provided with a section of non-anastomosis area B26 at the left and the right sides respectively. Of course, the staple abutting seat assembly 21 of the endoscopic cutting stapler 2 can be lengthened, and the staple cartridge assembly 22 can be widened, so that a sufficient non-anastomosis area is reserved between the staple abutting seat assembly 21 and the staple cartridge assembly 22.
On one side of the nail abutting seat component 21, the fixing part 12 in the supporting gasket 1 is arranged on the head-tail side of the inosculating part 11, and the fixing part 12 is fixedly arranged in the non-inosculating area A26 through a fixing nail A27; on one side of the cartridge assembly 22, the fixing portions 12 of the supporting pad 1 are disposed on the left and right sides of the anastomosis portion 11, and the fixing portions 12 are fixed to the non-anastomosis region B28 by fixing nails B29.
The detailed working principle of the endoscope cutting anastomat is as follows:
as shown in fig. 7-10: by dividing the supporting gasket 1 into the anastomotic part 11 and the fixing part 12, the anastomotic part 11 is firmly arranged on the surface of the anastomotic region of the endoscopic cutting stapler through the fixing part 12, and the conditions of slippage and dislocation can not occur. After the anastomosis operation is carried out by the endoscope cutting anastomat, the anastomosis part 11 is left at the operation anastomosis opening along with the anastomosis nail 5, and the fixing part 12 leaves the human body along with the endoscope cutting anastomat or directly falls off to the human body to be automatically degraded.
After the supporting gasket is fixed on the disposable endoscope through the mode, the intestinal canal tissue is cut and anastomosed, and the lung lobe can be cut and anastomosed. When the disposable endoscope cutting anastomosis component is used for stimulating cutting anastomosis, the anastomosis nail 5 fixes the support gasket 1 on the tissue. Due to the existence of the easy-tearing structure, the intersection of the anastomosis part 11 and the fixed part 12 can be broken only by applying a slight force. So that when the anastomosis is cut, the jaws are opened and the anastomotic portion 11 and the fixation portion 12 are separated. The anastomotic portion 11 is fixed to the intestinal tract tissue to uniformly press the tissue, thereby achieving hemostasis.
Taking the circular stapler 3 as an example, the anastomosis structure of the circular stapler 3 mainly comprises a nail abutting seat part 31 and a nail bin part 32; the nail abutting seat part 31 comprises an annular nail abutting seat 311, a front cover 312 and a connecting rod 313, wherein a knife-padding ring 314 is arranged on the nail abutting seat 311; the cartridge member 32 includes a cartridge housing 321 and a cartridge 322. The nail abutting seat component 31 and the nail bin component 32 are both provided with anastomotic stoma supporting gaskets 1. As shown in fig. 22 and 23: the anastomotic part 11 of the anastomotic stoma supporting pad 1 is annular, and the fixing parts 12 are distributed at the outer side edge and the inner side edge of the anastomotic part 11; depending on the way of connection between the stoma support pad 1 and the circular stapler 3, several embodiments can be derived:
example 9
As shown in fig. 21: the outer fixing part of the anastomotic stoma supporting gasket 1 matched with the nail abutting seat component 31 is clamped between the nail abutting seat 311 and the front cover 312 to realize fixation; a first fixing ring 313 is provided on the inner side wall of the annular nail abutting seat 311, and a fixing portion on the inner side of the anastomotic stoma support shim 1 is held between the nail abutting seat 311 and the first fixing ring 313. Similarly, the fixing part at the outer side of the anastomotic stoma support gasket 1 matched with the nail bin component 32 is clamped between the nail bin sleeve 321 and the nail bin 322 to realize fixation; a second retainer ring 323 is provided on the inner wall of the magazine 321, and a fixing portion on the inner side of the stoma support shim 1 is held between the magazine case 321 and the second retainer ring 323.
Example 10
The fixing part 12 of the anastomotic stoma support gasket can be fixed on the inner side and the outer side of the nail abutting seat part 31 of the cavity circular anastomat 3 directly through nontoxic medical adhesive. Likewise, cartridge member 32 may be of the same design.
Based on the endoscope cutting anastomat and the circular anastomat, other types of anastomats such as a linear cutting anastomat and a linear anastomat can be reformed according to the same principle.
While the invention has been illustrated and described with respect to specific embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention.
