Abstract

The utility model discloses a novel pushing and knotting hook, which comprises a knotting hook and a handle, wherein the knotting hook is a joggling secondary step-shaped structure, and the hook partof the knotting hook is an opened small round shape which is vertical to the hook body part. The hook can excellently solve the problems that the sewing and the knotting are difficult during chronic dacryocystitis surgeries, the step-shaped knotting structure can control the inserting depth of the knotting hook, which is easier to observe, simultaneously the structure is very simple, and the manufacturing and the use are very convenient.

Description

A kind of novel line knotting hook that pushes away

Technical field

This utility model relates to a kind of operating theater instruments, and more particularly, this utility model relates to a kind of novel line knotting hook that pushes away.

Technical background

Chronic dacryocystitis is a kind of clinical ophthalmology common disease, frequently-occurring disease, and in the Therapeutic Method, dacryocystorhinostomy is again an a kind of desirable modus operandi the most reliable at present, that insure, meet most the physiological function requirement most.In dacryocystorhinostomy, the long period has been used in stitching and knotting, and it is little owing to wound when knotting to sew up the back, and the position is dark, and finger and routine operation apparatus are difficult for arriving, knotting easily causes often with nasal membrane or the drawing crack of lachrymal sac mucosa, so that sew up again, repeatable operation has increased wound, even cause to coincide and get nowhere, cause operative failure.

The utility model content

The purpose of this utility model is to overcome the problem that exists in the existing operative treatment, and a kind of novel line knotting hook that pushes away is provided, and solves the difficult problem of the masty wound suture knotting of conventional apparatus in the chronic dacryocystitis operation process.

This utility model is achieved by following technical proposals:

A kind of novel line knotting hook that pushes away is made up of knotting hook and handle, and the characteristics of its structure are: the hook body of described knotting hook partly is the step shape of warpage secondary, and the crotch of knotting hook partly is and the vertical opening small circular of hook body part.

Height with the handle horizontal positioned is a benchmark, and the hook body of described knotting hook partly is downward step shape, and the opening of the small circular of the crotch part of the hook of then tiing a knot upwards.

The diameter of the small circular of the crotch of described knotting hook part is 2～3mm, be connected with crotch straight-bar L1 length be 16～18mm.

The other end of described handle also is connected with the knotting hook of a linear type hook body.

This utility model has following advantage compared with prior art:

1, push away line knotting hook and when sewing up knotting, more can hook stitching thread easily, and volume is less, can avoid the easy off-line of common apparatus and cause nasal membrane or the problem of lachrymal sac mucosa drawing crack than previously used general tool.

2, the knotting hook is rifle shape structure, can control the insertion depth of knotting hook, and is easy to more observe.

3, structure is very simple, and making and use are all very convenient.

Description of drawings

Accompanying drawing 1 pushes away the overall structure sketch map of line knotting hook;

Knotting hook structure sketch map before the accompanying drawing 2;

Accompanying drawing 3 knot hook structure floor map.

In the accompanying drawing, knotting hook 1, linear type colludes the knotting hook 2 of body, handle 3.

The specific embodiment

A kind of novel line knotting hook that pushes away comprises knotting hook 1 and handle 3, and the hook body of described knotting hook 1 partly is the step shape of warpage secondary (being commonly called as rifle shape), and the crotch of knotting hook 1 partly is and the vertical opening small circular of hook body part.The diameter of the small circular of the crotch part of knotting hook is 2～3mm, is connected with crotch straight-bar L1 length be 16～18mm, not only be easy to insert wound, and be inserted into L when pushing away the line hook of tiing a knot ₁The degree of depth time, the turnover of step shape just can be prevented the further insertion of thrust line hook.

With reference to figure 2, height with handle 3 horizontal positioned is a benchmark, the hook body of described knotting hook 1 partly is downward step shape, and the opening of the small circular of the crotch part of the hook 1 of then tiing a knot makes progress, effectively the hook stitching thread, avoid multi-pass operation, reduced wound, after stitching is finished, knotting, left hand is held line after living on one side suture with the opening small circle hook (extensions) that pushes away line knotting hook, and the line hook of tiing a knot that pushes away that right hand tenaculum hooks suture pushes knot urgent gently.Rifle shape one end more is difficult for blocking surgical field of view, and the line depth degree that pushes away also easy to control can effectively prevent to overexert with the drawing crack of stitching mucosa.

With reference to figure 1 and another embodiment shown in Figure 3, in this embodiment, one end of handle 3 connects above-mentioned rifle shape knotting and colludes 1, the other end at handle 3, be connected with the knotting hook 2 that a linear type colludes body, straight shape one end all is convenient to regulate to the wound depth and is used, and can be inserted in the darker wound, and finger and routine operation apparatus were difficult for the place that arrives when this structure was equally applicable to nasal cavity (when sewing up knotting as nasal septal construction and NASAL SEPTAL PERFORATION REPAIR WITH) and waits the operation of other deeps.
