Description

Threading operation forceps

Technical Field

The utility model relates to an instrument for operation, in particular to threading operation forceps.

Background

During the operation, the suture is often needed to be sewed by using a surgical thread, and the suture is generally sewed by using a surgical needle.

The traditional operation threading needs to pass a surgical needle through a part to be sutured by a first forceps, then draw out the surgical needle by another forceps and pass through the part to be sutured from top to bottom, tighten a surgical thread after a plurality of times of threading and then suture. In the actual suturing process, the surgical thread is easy to fall off from the first forceps, so that the operation is troublesome because the thread needs to be threaded again; the surgical needle is clamped by the forceps, so that the surgical needle is extremely easy to clamp the part to be sutured, and secondary injury is caused.

Therefore, the traditional operation threading has the problems of troublesome operation and easy secondary injury.

The technical scheme of the utility model is as follows: threading surgical forceps, which comprises a front handle and a rear handle which are connected in a rotating way; the front end of the rear handle is connected with an outer tube, and a push rod and a wire feeding rod positioned below the push rod are arranged in the outer tube; the front end of the outer pipe is provided with a threading assembly, the threading assembly comprises a fixed head arranged at the front end of a thread feeding rod, a crochet hook rotatably arranged on the thread feeding rod, and a thread pressing elastic sheet arranged on the crochet hook; the tail end of the wire feeding rod is provided with a wire feeding handle machine positioned in front of the front handle; two ends of the push rod are respectively and rotatably connected with the crochet hook and the front handle; the fixed head is provided with a through hole connected with the wire feeding rod; the line pressing elastic sheet is positioned between the positioning head and the crochet hook; the crochet hook is bent, and the head of the crochet hook is conical; the head of the crochet hook is provided with a crochet hook groove.

In the threading surgical forceps, a horizontally arranged pin is arranged at the front end of the thread feeding handle machine; a vertically arranged screw is arranged below the outer pipe; the top of the wire feeding handle machine is provided with a connecting pin, and a sliding groove corresponding to the connecting pin is arranged below the tail end of the wire feeding rod.

In the threading surgical forceps, the rear handle is provided with a limit pin positioned at the tail end of the push rod; the top of the front handle is provided with a bayonet lock, and the tail end of the push rod is provided with a clamping groove corresponding to the bayonet lock.

Compared with the prior art, the outer tube is internally provided with the push rod and the thread feeding rod, the thread feeding rod is combined with the threading assembly, the crochet hook is driven by the push rod to rotate up and down through the handle before opening and closing, when the crochet hook rotates to the bottom, the thread hooking groove on the crochet hook hooks the operation thread on the fixed head, when the crochet hook rotates, the crochet hook drives the operation thread to ascend so as to carry out sewing (when in use, the fixed head is positioned below the sewing position, the crochet hook is positioned above the sewing position, and the crochet hook can pass through the sewing part to hook out the operation thread during sewing so as to realize sewing), two operation clamps are not needed to carry out sewing, the operation thread can be sewn only through opening and closing the front handle, and the operation is simpler and more convenient compared with the traditional sewing; the utility model is adopted to carry out surgical suture, and surgical needles or surgical threads do not need to be clamped by using surgical forceps, thereby avoiding the possibility of secondary injury and having better safety.

Therefore, the utility model has the advantages of relatively simple and convenient operation and no secondary damage.

Furthermore, through set up the spacer pin at the push rod end, prevent that the push rod from pulling behind too much and make the crochet hook upwards rotate at the restriction within range, stop its rotation and too big cause the injury to the patient.

Detailed Description

The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.

Examples are given. Threading forceps, constructed as shown in fig. 1-5, comprising a front handle 10 and a rear handle 12 rotatably connected; the front end of the rear handle 12 is connected with an outer tube 6, and a push rod 5 and a wire feeding rod 2 positioned below the push rod 5 are arranged in the outer tube 6; the front end of the outer tube 6 is provided with a threading assembly, the threading assembly comprises a fixed head 1 arranged at the front end of a thread feeding rod 2, a crochet hook 4 arranged on the thread feeding rod 2 in a rotating way, and a thread pressing elastic sheet 3 arranged on the crochet hook 4; the tail end of the wire feeding rod 2 is provided with a wire feeding handle machine 9 positioned in front of a front handle 10; two ends of the push rod 5 are respectively and rotatably connected with the crochet hook 4 and the front handle 10; a through hole connected with the wire feeding rod 2 is formed in the fixed head 1; the thread pressing elastic sheet 3 is positioned between the positioning head 1 and the crochet hook 4; the crochet hook 4 is in a curved shape, and the head part of the crochet hook is in a conical shape; the head of the crochet hook 4 is provided with a crochet hook groove.

A horizontally arranged pin 8 is arranged at the front end of the wire feeding handle machine 9; a vertically arranged screw 7 is arranged below the outer pipe 6; the top of the wire feeding handle machine 9 is provided with a connecting pin, and a sliding groove corresponding to the connecting pin is arranged below the tail end of the wire feeding rod 2.

A limit pin 11 positioned at the tail end of the push rod 5 is arranged on the rear handle 12; the top of the front handle 10 is provided with a bayonet 101, and the tail end of the push rod 5 is provided with a clamping groove corresponding to the bayonet 101.

The working principle is as follows: after the operation thread is arranged in the utility model, the fixed heads 1 are arranged below the position to be sutured and are mutually attached, and the crochet hook 4 is positioned above the position to be sutured at this time. By opening and closing the front handle 10, the front handle 10 is opened and closed to drive the push rod 5 to move back and forth so as to drive the crochet hook 4 to rotate up and down. When the crochet hook 4 rotates downwards, the conical head of the crochet hook 4 can facilitate the crochet hook 4 to pass through the part to be sutured, and the crochet hook groove on the crochet hook 4 hooks the operation line at the fixed head 1. When the crochet hook 4 rotates upwards, the crochet hook groove drives the operation line to pass through the position to be sutured. The front handle 10 is opened and closed continuously, so that the crochet hook 4 rotates up and down continuously, and the operation line is driven to pass through the position to be sutured to realize suturing (the suturing principle is the same as that of a sewing machine). During suturing, the surgical thread is pressed by using the thread pressing spring 3.
