Abstract

The utility model discloses a knot-tying device for a deep part. The utility model is characterized in that one end of a rod piece is a knot-tying head on which a concave groove is arranged; the other end of the rod piece is provided with a handle; two annular holes are arranged in the handle; the middle part of the handle approximately forms a V-shaped groove. The whole external shape of the utility model is close to the external shape of a fastened hemostat so that convenience is offered for extending the utility model into a deep part to tie a knot, wherein, fingers can not reach the deep part. The utility model has the advantages of no drop for thread knots and quick knotting, being particularly suitable for surgical operations with small incisions. Through experiments, the knotting speed of the utility model is more than three times as fast as a hemostat.

Description

A kind of Knotter applicable deep part

This utility model relates to the technical field of medical equipment, specifically a kind ofly can be used for operating Knotter applicable deep part.

Deep stitching thread in the existing surgical operation adopts two kinds substantially, a kind of is to strike knot with the hand, but it is little at otch, depths, position finger just can not enter into the position that needs ligation, another kind is to hold pincers knottings, though can enter into the position that the deep needs ligation, often can not once send into toe-in is tightened, not only slow but also toe-in easily comes off, and has spun out the quality of operating time and operation.

The purpose of this utility model is to provide a kind of Knotter applicable deep part, and it can be sent toe-in into the deep easily and tighten, and remedies finger and can not enter into the position that the deep needs ligation, replaces the existing pincers knotting of holding.

The technical solution of the utility model is achieved in that a kind of Knotter applicable deep part, and the approximate mosquito forceps that clamps of whole profile is characterized in that: an end of rod member is the knotting head, on the knotting head groove is arranged, the other end of rod member is a handle, and handle has two looping pits, and intermediate approximation is a V-shaped groove.For the ease of sending knot and avoiding the tissue of knotting place is caused damage, the knotting head of rod member one end is circular-arc or other pure shape, and the V-shaped groove end of other end handle is circular-arc, also is being provided with a Wire channel in building near place in the middle of the rod member.

The toe-in that this utility model will be drawn snaps in the groove of knotting head, can extend into the inaccessiable deep of finger by rod member ties a knot, owing to the handle meter is set as the handle-shaped of mosquito forceps, surgeon's use habit, on handle, have one to be circular-arc V-shaped groove, make toe-in both be not easy to come off, can deliver to the position rapidly again, be specially adapted to the operation of little otch, fast more than two times through testing comparable mosquito forceps knotting speed.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is an example structure sketch map of the present utility model

Fig. 3 is another example structure sketch map of the present utility model

The utility model will be further described below in conjunction with drawings and Examples.

Whole profile of the present utility model is similar to the mosquito forceps of clamping, one end of rod member 2 is knotting 3, knotting 3 has a groove, the general dark 2-5mm of groove, tissue for knotting place of not damaging, the knotting head is circular-arc or other pure shape, the other end of rod member 2 is a handle 1, handle 1 shape approximation is the handle of mosquito forceps, be that handle has two looping pits, intermediate approximation is a V-shaped groove, considers to be convenient to send knot, and the V-shaped groove top is circular-arc, in the middle of near rod member, locate also to be provided with a Wire channel in building, the V-shaped groove of this groove and handle all plays the fixed effect of threading, and it can make the knotting line can not come off and accelerate knotting speed, in the visual field, deep not really clearly under the situation, also ligature can be sent into exactly the position that needs ligation, the time can choose one wantonly in operation, this special sursery doctor maneuver in use duplicates with mosquito forceps, so feel to be accustomed to very much.

Embodiment one

The whole rustless steel that adopts, one end of rod member is the knotting head, and the pulley 4 of indent in the middle of also can be set on the knotting head, and the other end of rod member is a handle, the handle of the mosquito forceps the when shape approximation of handle is clamping, the place also is provided with the Wire channel in building of an approximate V-arrangement in the middle of the rod member.

Embodiment two

The whole rustless steel that adopts, one end of rod member is the knotting head, one knotting groove is arranged on the knotting head, groove depth 4mm, groove width 2mm, the top of groove is spherical, one lead-in wire groove 5 also can be set on the knotting head, the lead-in wire groove can be oblique, S shape or other shape, present embodiment adopts S shape lead-in wire groove that toe-in is entered in the knotting groove easily, and the place is provided with a V-arrangement Wire channel in building in the middle of the rod member, and the handle of the rod member other end has two looping pits, be a V-shaped groove in the middle of the handle, send the top of knot two V-shaped grooves all to be circular-arc for ease of threading.

Claims
