Abstract
The utility model discloses a surgical suture needle for peritoneoscope partial nephrectomy. The surgical suture needle comprises a needle body and a suture. The needle body is connected with the suture through a needle end, the needle body is of an arc-shaped structure, noninvasive connection is adopted in the needle end and the suture, and a stopper is arranged at the tail end of the suture. The stopper is of a cuboid thin sheet structure, and the suture is perpendicular to the cuboid thin sheet. The surgical suture needle can suture the nephridial tissue in a long-span mode, knotting fixation is not needed, the suturing firmness is improved, and the surgical suture needle is especially suitable for nephridial tissue suturing surgery such as peritoneoscope partial nephrectomy due to the fact that the tail end of the surgical suture is provided with the stopper.
Description
Technical field
This utility model relates to technical field of surgical instruments, relates in particular to a kind of laparoscopic partial nephrectomy operation sewing needle.
Background technology
Laparoscopic partial nephrectomy of the prior art has become the main modus operandi of the early stage tumor of kidney for the treatment of, and it is little that it has operation wound, recovers fast, can maximumly preserve the advantages such as renal function.But laparoscopic partial nephrectomy operation technique limited space, sews up span large, complicated by current conventional sewing needle sew application under peritoneoscope, knotting difficulty, sews up imprecisely, has often increased the operation easier of operation, has limited carrying out of operation.Current conventional Urology Surgery sewing needle length is all shorter simultaneously, cannot extend entirely through kidney anteroposterior diameter, while making to sew up, cannot definitely sew up nephridial tissue; Current conventional sewing needle radian is excessive, and kidney is difficult for running through pin while sewing up.
Summary of the invention
The purpose of this utility model is exactly the problem existing in order to solve prior art; A kind of laparoscopic partial nephrectomy operation sewing needle is provided; This sewing needle can not only large span be sewed up nephridial tissue, and does not need knotting fixing, has improved stitching fastness, with end-stop device, is particularly useful for the operation stitching nephridial tissues such as laparoscopic partial nephrectomy.
This utility model adopts following technical scheme:
An operation sewing needle, comprises needle body, suture and end-stop device, and needle body is connected with suture by backshank, and needle body adopts arcuate structure, and described backshank adopts and is connected without wound with suture, and described sutures end is provided with stopper.
Described needle body adopts arc-shaped structure, and radian is 120 ° (i.e. 1/3 radians), and chord length is 6cm.While being applicable to sew up, inserting needle goes out pin, can fully run through kidney, has avoided again long caused use inconvenience.Sewing needle should with stitching thread one, for without wound sewing needle, be more convenient to operation technique.
Described suture length is 10cm, and suture adopts compound suture material.
Described suture adopts PGLA material to make, and suture length is moderate, and length meets the needs of laparoscopic surgery.
Described stopper adopts the medical multi-polymer material of nonabsorable.
Described stopper adopts cuboid flake structure, and described suture is vertical with cuboid thin slice.
The beneficial effects of the utility model:
This utility model, by the abundant thicker organ-tissue of through and through suture of this suture needle, is avoided the complex operations such as knotting, sews up fixing definitely, is applicable to the laparoscopic surgery operations such as laparoscopic partial nephrectomy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that this utility model is sewed up and suture clamps schematic diagram;
In figure, 1. needle body, 2. suture, 3. stopper, 4.hem-o-lok folder.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, this utility model is described further.
A kind of laparoscopic partial nephrectomy operation sewing needle, in conjunction with Fig. 1, Fig. 2, comprise needle body 1, suture 2, needle body is connected with suture by backshank, and the tight connecting device that backshank is integrated with suture, employing are connected without wound, the needle point of needle body is circular needle point, needle body adopts arcuate structure, and described sutures end is provided with stopper 3, and described stopper and suture are fixed as one.Needle body adopts arc-shaped structure, and radian is 120 ° (i.e. 1/3 radians), and chord length is 6cm.While being applicable to sew up, inserting needle goes out pin, can fully run through kidney, has avoided again long caused use inconvenience.Sewing needle should with stitching thread one, for without wound sewing needle, be more convenient to operation technique.
Suture length is 10cm, and suture adopts compound suture material.Suture adopts PGLA (910 polymeric polyglycolide-polylactide) material to make, and suture length is moderate, and length meets the needs of laparoscopic surgery.
Described stopper adopts the medical multi-polymer material of nonabsorable.Described stopper adopts cuboid flake structure, and described suture is vertical with cuboid thin slice.
Described suture, after sewing up, tightening up, is pressed from both sides suture folder is closed by hem-o-lok.By hem-o-lok, press from both sides and make suture play suturing, avoided complicated knotting operation under peritoneoscope.Adopt conventional hem-o-lok tissue holder, avoided tearing nephridial tissue, played abundant fixation, avoided again the excessive operation technique that affects of volume.
When this utility model is expert at the thicker tissue apposition in the deep such as kidney, can be easier to run through the vertical footpath of tissue with abundant suture tissue, the end-stop device shape fixation of weighing anchor, after sewing up, only suture need be tightened up and with hem-o-lok folder folder, close suture and can play suturing, avoid complicated knotting operation under peritoneoscope.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of utility model is described; but the not restriction to this utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
