Abstract
The utility model relates to surgery instruments, in particular to a tubular anastomat with a stay wire. The tubular anastomat comprises a movable handle, an anastomat body, a nail drill, a nail bin, a nail drill rod and the stay wire. The front end of the anastomat body is connected with the nail drill, the back end of the anastomat body is connected with the movable handle, and the nail bin is provided with a nail box, a nail base and an anastomat nail. The top of the nail drill is movably connected with the nail drill rod, and the nail base is movably connected with the nail box in a meshed mode. At least one stay wire is arranged at the front end of the anastomat nail. The anastomotic stoma tissue can be pulled downwards and inwards through the stay wire under the situation that the anus is expanded fully, the stay wire is nailed on the anastomotic stoma after anastomosing stimulation, the anastomotic stoma of the anus can be reinforced and sutured through the stay wire which becomes a supporting wire for supporting and pulling the anastomotic stoma tissue via the anus, the purpose of thoroughly removing the anastomotic stoma leakage is achieved, the international medical problem of the low rectum anastomotic stoma leakage especially the low rectal cancer surgical anastomotic stoma leakiness existing in an existing tubular anastomat is solved, two-time surgical pain suffered by patients is avoided, and medical cost is reduced.
Description
Technical field
This utility model relates to a kind of surgical apparatus, especially relates to a kind of band bracing wire circular stapler.
Background technology
At present, at medical science surgery mid-low rectal cancer, protect anus operation because of anastomotic fistula incidence rate high (approximately 10%～20%), most patient adopts proximal colonic or little intestine fistulization to reduce the generation of rectum anastomotic leakage when radical operation for the first time.Patient need select a time and carry out the ostomy art of also receiving of prevention the 2nd time after operation for the first time, and this not only causes the misery of second operation to patient, and increases the financial burden of approximately 30,000 yuan.
The applicant discloses the not isometric anastomosis staple of a kind of ellipse and renovates circular stapler in Chinese patent 201310374625.X, is provided with flexible handle, device body, oval nail bit, oval nail bin and nail bit bar; The front end of device body is connected with oval nail bit, and the rear end of device body is connected with flexible handle, and described oval nail bin is provided with oval nail kit, oval nail seat, first group of anastomosis staple and second group of anastomosis staple; The top of described oval nail bit is flexibly connected with nail bit bar, the top major axis of described oval nail bit and the angle of nail bit bar are greater than 90 °, the top minor axis of described oval nail bit and the angle of nail bit bar equal 90 °, the length of described first group of anastomosis staple is 35%～95% of second group of anastomosis staple length, oval nail seat is associated with oval nail kit operability, and oval nail seat is coincide and is connected with oval nail kit activity.
The applicant discloses a kind of sandwiched stapler type alimentary tract anastomosis dissecting sealer in Chinese patent CN202146325U, is provided with nail anvil (also claiming end needle stand), nail bin (also claiming staple cartridge), device body, flexible handle, adjustment knob, edge bearing and anastomosis staple (also claiming suturing nail); Nail anvil is connected with the leading section of device body, adjustment knob is located at the afterbody of device body, flexible handle is located at the rear portion of device body, the junction of flexible handle and device body is provided with stop button, edge bearing is located on nail anvil, and anastomosis staple is located at the leading section of device body, on the surface of nail anvil (also claiming end needle stand), is provided with membranoid substance, surface at nail bin (also claiming staple cartridge) is provided with membranoid substance, forms the sandwich structure of membranoid substance+intestinal wall+membranoid substance after stitching.
Summary of the invention
The purpose of this utility model is for existing circular stapler, to have the problems such as low rectal anastomotic leakage, and a kind of band bracing wire circular stapler is provided.
This utility model is provided with flexible handle, device body, nail bit, nail bin, nail bit bar and bracing wire; The front end of device body is connected with nail bit, and the rear end of device body is connected with flexible handle, and described nail bin is provided with nail kit, nail seat, anastomosis staple; The top of described nail bit is flexibly connected with nail bit bar, and nail seat is coincide and is connected with nail kit activity; Described bracing wire is provided with at least 1, and bracing wire is located at anastomosis staple front end position.
Described bracing wire can be provided with 2～40, and the distance between adjacent bracing wire can be 2～30mm; Bracing wire can adopt degraded line or non-degradable line.
The method that described bracing wire is placed can be multiple, but final purpose is to follow closely in anastomotic stoma after bracing wire is coincide.
Compared with prior art, the utlity model has following advantage:
This utility model first using surgical thread as stand-off in rectum anastomotic stoma, it is surgical thread to be preset to anastomosis staple or anastomat front end position on the basis of existing circular stapler, by bracing wire, in the situation that fully expanding anus, can be downward to anastomotic stoma tissue, inside tractive, followed closely in anastomotic stoma exciting the back guy that coincide simultaneously, can under the help of bracing wire, to anastomotic stoma, reinforce stitching by per anum, become the Support Level that per anum supports tractive anastomotic stoma tissue, reach the object of thorough removing anastomotic leakage, solved the low rectal anastomotic leakage that existing circular stapler exists, especially the international difficult medical problem of operation of low rectal carcinoma anastomotic stoma leakiness, make patient exempt the misery of 2 operations, also reduce medical expense.
Accompanying drawing explanation
Fig. 1 is that the structure of this utility model embodiment forms schematic diagram.
Fig. 2 is that nail bit, the nail bin of this utility model embodiment are, the structure of bracing wire forms schematic diagram.
Fig. 3 is that the stand-off of this utility model embodiment is in the view of anastomotic stoma.
Fig. 4 is the view that anastomotic stoma tissue is supported in the bracing wire of this utility model embodiment.
The specific embodiment
Referring to Fig. 1～4, this utility model embodiment is provided with flexible handle 1, device body 2, nail bit 3, nail bin 4, nail bit bar 5 and bracing wire 6; The front end of device body 2 is connected with nail bit 3, and the rear end of device body 2 is connected with flexible handle 1, and described nail bin 4 is provided with nail kit 41, nail seat 42, anastomosis staple 43; The top of described nail bit 3 is flexibly connected with nail bit bar 5, and nail seat 42 is connected with movable the coincideing of nail kit 41; Described bracing wire 6 is provided with 20, and 20 bracing wires 6 are located at anastomosis staple 43 front end positions, and the distance between adjacent bracing wire is 2～20mm.
Described bracing wire 6 adopts degraded line.
The method that described bracing wire is placed can be multiple, but final purpose is to follow closely in anastomotic stoma after bracing wire is coincide.
During operation, by bracing wire 6, in the situation that fully expanding anus, to downward, the inside tractive of anastomotic stoma tissue, excite the back guy 6 that coincide to be followed closely in anastomotic stoma simultaneously, can under the help of bracing wire 6, to anastomotic stoma, reinforce stitching by per anum, become the Support Level that per anum supports tractive anastomotic stoma tissue, reach the object of thorough removing anastomotic leakage, solved the low rectal anastomotic leakage that existing circular stapler exists.In Fig. 2～4, labelling 7 is intestinal wall.
