Description

Needle holder assists knotting device under peritoneoscope

Technical Field

The utility model relates to the technical field of medical equipment, specifically speaking, in particular to supplementary knotting device of needle holder under peritoneoscope.

Background

Knotting by using a needle holder under a laparoscope is a basic work of a minimally invasive surgeon, but the knotting under the laparoscope is not easy due to the lever, the angle and the like of the needle holder of the laparoscope, and particularly the quick knotting is difficult to guarantee; the root of the needle is that the thread is easy to slip off the needle holder, which causes difficult winding and time and labor waste; especially, in emergency such as suturing bleeding blood vessels under an endoscope, the success or failure of direct operation can be caused by knotting speed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the embodiment of the utility model provides an auxiliary knotting device for a needle holder under a laparoscope. The technical scheme is as follows:

in one aspect, a needle holder assisted knotting device under a laparoscope is provided, comprising: a main body and a boss; the main body is annular and is sleeved on the neck of the needle holder under the laparoscope; the outer side of the main body is provided with the bulge; the protrusions comprise a first protrusion, a second protrusion and a third protrusion; the first bulges, the second bulges and the third bulges are uniformly distributed on the outer side of the main body.

Further, the main body and the protrusions are made of rubber.

Furthermore, the protrusions are in a circular truncated cone structure; the top of the convex round table is connected with the main body.

Further, the length of the protrusion is 0.3 cm. The diameter of one end of the bulge is 0.2cm, and the diameter of the other end of the bulge is 0.1 cm.

The embodiment of the utility model provides a beneficial effect that technical scheme brought is:

the utility model provides a supplementary knotting device of needle holder under peritoneoscope, adopt the loop configuration, the cover is established at the neck of needle holder under the mirror, the material adopts rubber to make, have elasticity, can very relax very stable tight suit needle holder apart from about 0.2cm of needle holder head, fix well; meanwhile, the lug bosses are arranged, have toughness and are evenly distributed in the directions of 12 points, 4 points and 8 points of the main body; the bulge part prevents the phenomenon that the thread slips off the needle holder due to the angle and the material of the thread when the thread is wound; after the thread is wound successfully and knotted, the two ends of the thread head are pulled in, and the thread is easy to slip off from the thin rod and can be knotted smoothly because the force is increased and the bulge part is soft and tough. The thin rods are evenly distributed in the directions of 12 points, 4 points and 8 points of the main body to adapt to the rotation, the angle and the like of the needle holder, and smooth winding is guaranteed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The utility model provides a supplementary knotting device of needle holder under peritoneoscope, see figure 1, include: a main body 1 and a boss 2; the main body 1 is annular and is sleeved on the neck of a needle holder under the laparoscope; the outer side of the main body 1 is provided with the bulge 2; the protrusions 2 comprise a first protrusion 21, a second protrusion 22 and a third protrusion 23; the first protrusions 21, the second protrusions 22 and the third protrusions 23 are uniformly distributed on the outer side of the main body 1.

In the present embodiment, the first, second and

third protrusions

21, 22 and 23 are evenly distributed in the 12, 4 and 8 point directions of the body

In other embodiments, other numbers of protrusions can be arranged according to requirements, and the position intervals of the protrusions can be adjusted according to requirements.

Further, the main body and the protrusions are made of rubber.

Furthermore, the bulge is of a circular truncated cone structure; the top of the convex round table is connected with the main body.

In the embodiment, referring to fig. 2 and 3, the main body 1 adopts an annular structure, is sleeved on the neck of the needle holder 3 under the mirror, is made of rubber, has elasticity, can be easily and stably sleeved on the needle holder at a position which is about 0.2cm away from the head of the needle holder, and is well fixed; meanwhile, a bulge is arranged, the bulge is a thin rubber rod with the tail end slightly expanded and the length of about 0.4 cm; the protrusions have toughness and are evenly distributed in the 12-point, 4-point and 8-point directions of the main body; the bulge part prevents the phenomenon that the thread slips off the needle holder due to the angle and the material of the thread when the thread is wound; after the thread is wound successfully and knotted, the two ends of the thread head are pulled in, and the thread is easy to slip off from the thin rod and can be knotted smoothly because the force is increased and the bulge part is soft and tough. The thin rods are evenly distributed in the directions of 12 points, 4 points and 8 points of the main body to adapt to the rotation, the angle and the like of the needle holder, and smooth winding is guaranteed.

In the specific winding process, referring to fig. 2, the tension of the wire 4 is small, and the protrusion 2 enables the wire 3 to be hung, so that the winding of the needle holder is facilitated.

When knotting, see fig. 3, the thread 4 is under high tension and the protrusions 2 can deform under the action of the thread 4 to allow the thread to pass over.

The above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
