Description
Technical Field
The utility model relates to an operating forceps, in particular to an operating forceps with a puncture function.
Background
The operating forceps are used for shearing dressing, human epidermal tissue or soft tissue; in a minimally invasive surgery, a puncture outfit needs to be used for puncturing human tissues to form a puncture hole, and then the operation is carried out by using operating forceps, so that the puncture outfit and the operating forceps need to be used alternately. In the alternate process, the puncture outfit and the operating forceps are shuttled back and forth to the tissues of the human body, which is inconvenient to use and easy to enlarge the wound.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a needle type surgical forceps, the function of will puncturing and surgical forceps is integrated into an organic whole, avoids two kinds of apparatus alternate use and makes a round trip to shuttle in human tissue.
In order to solve the technical problems, the technical scheme of the utility model is that a needle type surgical forceps is adopted, which comprises a forceps body and a sleeve, wherein the front end of the sleeve is reduced to form a puncture needle tube for puncturing human tissues; the operating forceps body is accommodated in the sleeve, and the forceps jaws of the operating forceps body can extend out of the puncture needle tube. The utility model discloses a principle lies in with the operation pincers integrated with the puncture ware in, the back is punctured to human tissue to the puncture needle tubing, the pincers jaw (the work portion) extensible of operation pincers can go out the puncture needle tubing and operate, and need not to dial the puncture needle tubing and get into the human operation with the operation pincers again from the puncture hole after the human body.
As an improvement, a track extending along the axial direction of the sleeve is arranged in the sleeve, and a support rod is arranged on the surgical forceps body; the end part of the supporting rod is matched with the rail to slide. The supporting rod is utilized to support the surgical forceps, so that the stability of the surgical forceps is improved, and the surgical forceps can move back and forth in the sleeve conveniently.
As a further improvement, the device also comprises a sliding block which is matched with the track to slide, and the supporting rod is connected with the sliding block. The sliding stability can be improved by matching the sliding block with the track.
As another further improvement, the surgical forceps further comprise a return spring arranged in the track for urging the jaws of the surgical forceps body to retract. After the operation is finished, the operating forceps retract into the sleeve under the action of the return spring, so that secondary operation is facilitated.
As an improvement, the return spring is arranged at one end of the track close to the puncture needle tube.
As an improvement, the surgical forceps body comprises a left forceps body and a right forceps body which are hinged on a rotating shaft and can rotate around the rotating shaft; the support rod is an axial extension section of the rotating shaft. The left and right forceps bodies move relatively when cutting and other operations are carried out, and only the rotating shaft is relatively static. Therefore, the two ends of the rotating shaft are extended to form the supporting rods, so that the stability of the surgical forceps is ensured, and the operation of the surgical forceps is not hindered.
As an improvement, the two rails are arranged up and down, and two ends of the supporting rod are respectively clamped in the rails and slide in a matched manner with the rails; the side wall of the sleeve is provided with an axial long hole at the back of the track; one end of the support rod penetrates through the track and the long hole to extend out of the side wall of the sleeve, and a positioning nut is sleeved at one end of the support rod penetrating through the sleeve. The two rails further improve the stability of the forceps. And the position of the surgical clamp body can be fixed by screwing the positioning nut.
The utility model discloses an useful part lies in: the surgical forceps with the structure integrates the surgical forceps into the puncture outfit. After puncture, the forceps jaws of the operating forceps can be directly extended out of the puncture needle tube to carry out operation without pulling the puncture needle tube away from the human body. Therefore, the number of times that the puncture outfit and the operating forceps alternately shuttle in the human tissue is reduced, the wound is prevented from being enlarged, and the operation is convenient. In addition, because the operation is clamped in the sleeve, the obstruction of human tissues can be avoided during operation, and meanwhile, the tissues can be prevented from being accidentally injured by the operation forceps.

Fig. 2 is a schematic view of the axial vertical sectional structure of the present invention.
The labels in the figure are: 1 sleeve, 2 puncture needle tubes, 3 operating forceps bodies, 4 support rods, 5 tracks, 6 sliding blocks, 7 reset springs and 8 adjusting nuts.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in figures 1 and 2, the utility model comprises an operating forceps body 3, the operating forceps body 3 comprises a left forceps body and a right forceps body, and the left forceps body and the right forceps body are hinged on a rotating shaft and can rotate around the rotating shaft. The puncture needle comprises a sleeve 1, wherein the front end of the sleeve 1 is reduced in diameter to form a puncture needle tube 2 for puncturing human tissues; the surgical forceps body 3 is accommodated in the sleeve 1, and the forceps jaws of the surgical forceps body 1 can extend out of the puncture needle tube 2. For the convenience of puncture, the front section of the puncture needle tube 2 is a tip. For ease of operation, it is foreseen that the jaw shank portion of the forceps body 3 is external to the sleeve 1.
A track 5 extending along the axial direction of the sleeve 1 is arranged in the sleeve 1, and a support rod 4 is arranged on the operating forceps body 3; the end of the support rod 4 is matched with the rail 5 to slide. The support rod 4 is an axial extension section of the rotating shaft. The device also comprises a sliding block 6 which is matched with the track 5 to slide, and the supporting rod 4 is connected with the sliding block 6. And a return spring 7 arranged in the track 5 for promoting the retraction of the jaws of the forceps body 1. A return spring 7 is arranged in the track 5 near one end of the puncture needle tube 2. The two rails 5 are arranged up and down, and two ends of the supporting rod 4 are respectively clamped in the rails 5 and slide in cooperation with the rails 5; the side wall of the sleeve 1 is provided with an axial long hole at the back of the rail 5; one end of the support rod 4 penetrates through the rail 5 and the long hole to extend out of the side wall of the sleeve 1, and a positioning nut 8 is sleeved at one end of the support rod 4 penetrating through the sleeve 1. Of course, both ends of the support rod 4 may penetrate through the sleeve 1 and be provided with the positioning nuts 8.
