Description
Technical Field
The utility model belongs to the technical field of the field and specifically relates to an used sewing needle mounting structure of stitching instrument.
Background
In laparoscopic suturing, the suture needle is driven to rotate continuously to suture the postoperative tissue. When the existing suture needle is arranged in an arc-shaped slideway at the head part of a laparoscopic suture instrument, the suture needle is generally directly held by hands or is clamped by a clamp to be placed in an arc-shaped groove of a swinging head at the front end of the suture instrument, the placing form is random, the rotation of the suture needle is driven by a swinging rod arranged on the swinging head, the existing operation cannot ensure that the needle groove of the suture needle is aligned with the position of an ejector rod at the end part of the swinging rod, when the swinging rod swings, the ejector rod is difficult to be instantly clamped into the needle groove, the relative sliding between the ejector rod and the suture needle is easy to generate, and the rotation precision of the suture needle is reduced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a suture needle mounting structure for a suture device, which ensures that a mandril is clamped into a suture needle groove in time and improves the rotation precision of a suture needle.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an used sewing needle mounting structure of stitching instrument is located stitching instrument yaw front end, yaw front end be equipped with the arc slot of placing the sewing needle, promote the rotatory pendulum rod of sewing needle and establish on the yaw and the ejector pin of pendulum rod front end is located arc slot end, has the installation cutting ferrule, tip is equipped with the needle file before the installation cutting ferrule, and the sewing needle is needle point backshank outwards or needle point backshank inwards and blocks and establish on the needle file for the stylolite of sewing up the human tissue is connected at the backshank, the needle file is needle point backshank inwards or needle point backshank outwards state when cooperating with arc slot joint and arranges the arc slot in, the ejector pin card is gone into the needle inslot of sewing needle tip.
Furthermore, the needle seat is provided with a front bulge, a rear bulge and a side bulge which are circumferentially distributed and used for clamping the suture needle.
The utility model has the advantages that: the utility model discloses a sewing needle point needle tail is towards the yaw outside simultaneously, or sewing needle point needle tail is towards the inboard mounting structure of yaw simultaneously, when the pendulum rod drives the sewing needle rotatory, can ensure that the instant card of ejector pin goes into the needle inslot of sewing needle to improve the rotational accuracy of sewing needle.

In the figure: 1. the sewing machine comprises a swinging head, 2 parts of a sewing needle, 3 parts of an arc groove, 4 parts of a mounting clamping sleeve, 5 parts of a needle seat, 6 parts of a sewing thread, 7 parts of a front bulge, 8 parts of a rear bulge and 9 parts of a side bulge.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
A suture needle mounting structure for a suturing device shown in FIGS. 1 to 4 is provided at the front end of a swing head 1 of the suturing device, and the mounting structure achieves the following objects: when the sewing needle is arranged at the front end of the swinging head 1, the needle point and the needle tail of the sewing needle 2 face the outer side of the swinging head at the same time, or the needle point and the needle tail of the sewing needle 2 face the inner side of the swinging head at the same time.
Specifically, the front end of the swing head 1 is provided with an arc-shaped groove 3 for placing the sewing needle 2, the swing rod for pushing the sewing needle 2 to rotate is arranged on the swing head 1, and the ejector rod at the front end of the swing rod is positioned at the end part of the arc-shaped groove 3. The needle holder is characterized by further comprising an installation clamping sleeve 4, wherein a needle seat 5 is arranged at the front end of the installation clamping sleeve 4, and a front bulge 7, a rear bulge 8 and a side bulge 9 which are circumferentially distributed and used for clamping the suture needle 2 are arranged on the needle seat 5.
The first installation form is as follows: it is earlier the needle 2 that is needle point backshank outwards card between the back arch 8 and the side of needle file 5 and bulge 9 for sew up human tissue's stylolite 6 connection at the backshank, then will install the needle file 5 of needle 2 openly down, like this when needle file 5 and 3 joint cooperations of arc slot, needle 2 is needle point backshank and arranges in arc slot 3 inwards, at this moment the ejector pin just in time blocks into the needle inslot that 2 sharp-pointed ends of needle, and when the pendulum rod drove needle 2 rotatory, can ensure that the ejector pin blocks in the needle inslot of needle 2 immediately, thereby improves the rotational accuracy of needle 2.
The installation form II: it blocks between the preceding arch 7 of needle file 5 and side bulge 9 inwards to be earlier sewing needle 2 to be the needle point backshank for sewing up human tissue's stylolite 6 is connected at the backshank, then will install the needle file 5 of sewing needle 2 openly down, like this when needle file 5 and 3 joint cooperations of arc slot, sewing needle 2 is needle point backshank outwards arranges arc slot 3 in, at this moment the ejector pin just in time blocks the needle inslot of 2 needle tails of sewing needle, when the pendulum rod drives sewing needle 2 rotatory, can ensure that the ejector pin blocks the needle inslot of sewing needle 2 immediately, thereby improves sewing needle 2's rotation accuracy.
The utility model discloses a 2 needle point tails of sewing needle move towards the yaw outside simultaneously, or 2 needle point tails of sewing needle move towards the inboard mounting structure of yaw simultaneously, when the pendulum rod drives sewing needle 2 rotatory, can ensure that the instant card of ejector pin goes into the needle inslot of sewing needle 2 to improve sewing needle 2's rotation accuracy.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
