Description

Disposable needle-holding stitching instrument

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a disposable needle-holding stitching instrument.

Background

The disposable needle-holding suture instrument used in the existing laparoscopic surgery is generally of a jaw single-side opening structure and only has the function of clamping a suture needle, if the operation suture operation is to be completed, a doctor needs to rotate a wrist to complete the operation, but the suture operation is difficult to complete under the laparoscopic surgery, the positioning is inaccurate, a wound after treatment is not smooth enough, scars left after the operation are very obvious, and the later recovery effect of a patient is influenced.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: in order to overcome the defects in the prior art, the utility model provides the disposable needle-holding stitching instrument which is convenient for the cross operation application of forceps instruments and is more convenient and smoother to use.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a disposable needle-holding stitching instrument, includes fixed handle, with fixed handle articulated movable handle and install the claw beam at the fixed handle front end, wear to be equipped with the rear end in the claw beam and connect in fixed handle, control flexible wire rope by movable handle, the claw beam front end be fixed with the slider seat, the draw-in groove has been seted up to slider seat front end, the draw-in groove in be equipped with and be scissors form articulated last keep silent and keep silent down, seted up down arc groove on the connecting plate of last keep silent rear end, seted up last arc groove on the connecting plate of keep silent rear end down, the wire rope front end is connected with along arc groove down, go up arc groove orbit motion and promote keep silent and keep silent closed or open slider down.

Specifically, the slider seats on the two sides of the clamping groove are respectively provided with a long groove hole, the two sides of the slider are correspondingly provided with guide shafts, and the guide shafts are in sliding fit with the corresponding long groove holes after penetrating through the lower arc groove and the upper arc groove.

The utility model has the beneficial effects that: the utility model pulls the guide shafts on the two sides of the sliding block to move along the tracks of the lower arc groove and the upper arc groove respectively through the extension of the steel wire rope, thereby pushing the upper jaw and the lower jaw to perform closing or opening movement, realizing the clamping or loosening of the suture needle, having reasonable integral structure design, facilitating the application of cross operations of instrument forceps and the like by pulling the upper jaw and the lower jaw in two directions, having faster, more accurate and smoother use, and being more beneficial to the operation of laparoscopic surgery.

Drawings

The utility model is further described below with reference to the drawings and the embodiments.

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is an enlarged structural view of the upper jaw and the lower jaw of the utility model.

Fig. 3 is a schematic view of the mounting structure of the upper jaw and the lower jaw after the slider seat is removed in fig. 2.

In the figure: 1. the novel clamp comprises a fixed handle, 2 parts of a movable handle, 3 parts of a clamp rod, 4 parts of a steel wire rope, 5 parts of a sliding block seat, 6 parts of a long groove hole, 7 parts of an upper jaw, 8 parts of a lower jaw, 9 parts of a sliding block, 10 parts of a guide shaft, 11 parts of a lower arc groove and 12 parts of an upper arc groove.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1 to 3, the disposable needle-holding suturing instrument comprises a fixed handle 1, a movable handle 2 hinged with the fixed handle 1, and a forceps rod 3 mounted at the front end of the fixed handle 1, wherein a steel wire rope 4 with the rear end connected with the fixed handle 1 and controlled to stretch by the movable handle 2 is arranged in the forceps rod 3 in a penetrating manner.

The front end of the clamp rod 3 is fixed with a slide block seat 5, the front end of the slide block seat 5 is provided with a clamping groove, the side plates of the slide block seat 5 positioned at the two sides of the clamping groove are respectively provided with a long slotted hole 6, the clamping groove is internally provided with an upper jaw 7 and a lower jaw 8 which are hinged in a scissor shape, the front end of the steel wire rope 4 is connected with a slide block 9, the slide block 9 comprises a body and guide shafts 10 which are arranged at the two sides of the body and correspond to the long slotted holes 6, the rear end of the slide block 9 body is connected with the steel wire rope 4,

the clamping ends of the upper jaw 7 and the lower jaw 8 are positioned on the same side of the sliding block 9, the two clamping ends are respectively perpendicular to the jaw where the two clamping ends are positioned, a lower arc groove 11 is formed in a connecting plate at the rear end of the upper jaw 7, an upper arc groove 12 is formed in a connecting plate at the rear end of the lower jaw 8, and the guide shaft 10 penetrates through the lower arc groove 11 and the upper arc groove 12 and then is in sliding fit with the corresponding long groove hole 6.
