Abstract
The invention belongs to the technical field of medical apparatus and instruments used in a surgical minimally invasive surgery, and relates to a needle holder used for the surgical minimally invasive surgery. The needle holder used for the surgical minimally invasive surgery comprises the needle holder and a handle, and is characterized in that: the handle is connected with a needle holder rod of the needle holder; the open and close of two chunks are controlled by the needle holder rod; the hinge part of the handle is provided with a control knob; and the up and down movement angles of the two chunks of the needle holder are controlled by the control knob. The movement angles of the two chunks of the needle holder can reach 90 degrees. The needle holder for the surgical minimally invasive surgery has the advantages that: various angles of the chunks of the needle holder can appear under the control of the control knob on the hinge part of the handle, so sutures, such as such as up-and-down suture, can be performed on wounds at various angles in clamping sutures. Because the angles of the chunks can be transformed, a minimally invasive surgery has simpler, more convenient and easier suture knots, which can shorten surgery time, reduce the dosage of an anesthetic, increase surgical safety, and reduce the surgical risk of a patient.
Description
Technical field
The present invention relates to a kind of surgery Minimally Invasive Surgery technical field of medical instruments, be specifically related to a kind of architecture advances that is used for the needle holder of surgery Minimally Invasive Surgery.
Background technology
In the surgery Minimally Invasive Surgery, especially sewing up in the endoscope-assistant surgery is important link in the operation.Sew up at present is that the pin that adopts needle holder to clip band wire is sewed up knotting under the mirror of chamber.Because the stitching of this operation is to carry out in the mirror of chamber, be not easy very much operation, and existing needle holder all is straight up and down to enter wound, control the unusual difficulty of trend of needlework well, the stitching of carrying out left and right directions also needs the operation training of long period.
Adopting the knotting of existing needle holder need take a lot of operating times, mainly is that needle holder is that the direction of vertical wound surface enters wound, and two angle of nip degree causing the coiling knotting very difficult less than 70 degree.Because of needle holder enters the wound angular relationship, difficulty is bigger when wound suture up and down, causes the prolongation of operating time.And patient's anesthesia and operating time length can cause the raising of operation risk, and this also is one of reason of the difficult grasp of present laparoscopic technique.
Summary of the invention
Technical problem to be solved by this invention provides a kind of needle holder that is used for the surgery Minimally Invasive Surgery, makes stitching knotting technology become easy.Shorten operating time greatly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of needle holder that is used for the surgery Minimally Invasive Surgery, comprise needle holder and handle, it is characterized in that: described handle is connected with the needle holder bar of described needle holder, and the folding by two chucks of needle holder bar control, the articulated section of described handle is equipped with control handle, and two up and down angles of chuck of described needle holder are controlled by described control handle.
Two chuck activity point of view of described needle holder can reach 90 degree.
Therefore beneficial effect of the present invention is: the needle holder chuck all angles can occur under the control of handle articulated section control handle, can sew up the wound of various angles when holding suture needle adding, such as sewing up up and down.Because of the convertible angle of chuck, make the suture knotting in the Minimally Invasive Surgery easier to be easy, can shorten operating time, reduce narcotic consumption, thereby increase the safety of operation, reduce patient's operation risk.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is needle holder two collet segment rotational angle sketch maps of the present invention.
Among the figure: 1,2-chuck; 3-needle holder bar; The 4-control handle; The 5-handle.
The specific embodiment
Structural representation of the present invention is illustrated in Fig. 1, as seen from the figure, a kind of needle holder that is used for the surgery Minimally Invasive Surgery, comprise needle holder and handle 5, it is characterized in that: described handle 5 interconnects with the needle holder bar 3 of described needle holder, and pass through the folding that needle holder bar 3 is controlled two chucks 1,2, and the articulated section of described handle 5 is equipped with control handle 4, and two chucks of described needle holder, 1,2 up and down angles are subjected to described control handle 4 controls.
Fig. 2 is needle holder two collet segment rotational angle sketch maps, and the up and down angle that illustrates two chucks of described needle holder 1,2 can reach 90 degree.
The present invention is at needle holder handle place design knob, and the upper and lower activity of control chuck in the angle that adds adjustable clamps when holding suture needle, is beneficial to sew up the wound of various directions.As wound up and down, the wound of tilted direction.Make in the Minimally Invasive Surgery stitching in narrow space easier easily,, increase the angle of two pairs of pliers of intracavity, make the intracavity knotting become easy also because of clamp head part can rotate.
More than the description of the specific embodiment is intended in order to describe and the technical scheme that the present invention relates to be described, but be to be understood that the present invention is not limited to the specific embodiment discussed above.Based on enlightenment of the present invention, any conspicuous conversion or substitute and also should be considered to fall into protection scope of the present invention.
