Description

Retractor for laparoscopic surgery

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a retractor for laparoscopic surgery.

Background

With the progress and development of scientific technology, the operation mode is continuously improved and updated, the operation technology is gradually improved, the laparoscopic surgery in the minimally invasive technology is widely applied, especially the urinary surgery, compared with the traditional open surgery treatment, the laparoscopic surgery has less wound on the patient, the patient can be easily recovered after the operation, the pain borne by the patient is small, the complications are few, the hospitalization time is obviously shortened, but compared with the open surgery, fewer laparoscopic surgery auxiliary instruments are used, the operation space is less, the operation visual field is difficult to expose, the retractors in the market are mostly used for the open surgery to assist in exposing the visual field, no retractor which is applied to the abdominal cavity to help in exposing the visual field is available, when the laparoscopic surgery is performed, the main doctor often causes the operation difficulty due to poor visual field exposure, even an operation incision has to be opened on the abdominal part of the patient, and the visual field is exposed by the assistant, the tractor for laparoscopic surgery is provided because more trauma can be brought to a patient while manpower is wasted, and the requirement of the current use cannot be met.

SUMMERY OF THE UTILITY MODEL

In view of the deficiencies of the prior art, the present invention provides a retractor for laparoscopic surgery, which solves the problems set forth in the background art.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a tractor for laparoscopic surgery, includes first rotation tong bar, the one end of first rotation tong bar is provided with the torsional spring structure, the one end fixedly connected with second rotation tong bar of torsional spring structure, the second rotates the surface of tong bar and has seted up and has run through the groove, the tooth's socket has been seted up to the inboard of second rotation tong bar one end, one the inner chamber activity that runs through the groove has cup jointed the regulation band, the width of regulation band and the width looks adaptation that runs through the inslot chamber, the one end fixedly connected with drag hook of regulation band.

Optionally, the other end of the first rotary clamp rod is provided with a clamp head, and the inner surface of the clamp head is provided with a concave-convex groove.

Optionally, the width of the inner cavity of the through groove is matched with the width of the adjusting belt.

Optionally, the torsion spring structure is formed by combining two groups of torsion springs.

The utility model provides a retractor for laparoscopic surgery, which has the following beneficial effects:

1. this tractor for laparoscopic surgery, through the binding clip, the torsional spring structure, the regulation band, run through the groove, the cooperation of drag hook and tooth's socket is used, exert pressure to first rotation tong pole through the torsional spring structure, make the closed centre gripping of binding clip, utilize the torsional spring structure to rotate the tong pole to the second and exert pressure simultaneously, it is closed to make second rotation tong pole one end, utilize simultaneously to run through the groove and cup joint the regulation band, increase frictional force through the tooth's socket, it fixes the regulation band to make the second rotate the tong pole, use the binding clip to carry the stomach wall, catch the liver with the drag hook, length through the adjustment regulation band makes and produces pulling force to the drag hook, thereby utilize the pulling of drag hook to pull the tissue, the field of vision that will be operated is exposed, realized the function that the field of vision is exposed in the abdominal cavity help, the practicality of this tractor for laparoscopic surgery has been improved.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a partial structural schematic diagram of the present invention.

In the figure: 1. a first rotary nipper lever; 2. a second rotary nipper lever; 3. a torsion spring structure; 4. a binding clip; 5. a tooth socket; 6. pulling a hook; 7. an adjustment belt; 8. through the slot.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 2, the present invention provides a technical solution: a retractor for laparoscopic surgery comprises a first rotating claw beam 1, one end of the first rotating claw beam 1 is fixedly connected with a torsional spring structure 3, the other end of the first rotating claw beam 1 is provided with a binding clip 4, the torsional spring structure 3 is formed by combining two groups of torsional springs, two ends of one group of torsional springs are respectively connected with the first rotating claw beam 1, one end of the other group of torsional springs is fixedly connected with a second rotating claw beam 2, the inner side of one end of the second rotating claw beam 2 is provided with a tooth socket 5, an inner cavity of a through groove 8 is sleeved with an adjusting belt 7, one end of the adjusting belt 7 is fixedly connected with a drag hook 6, the surface of the second rotating claw beam 2 is provided with a through groove 8 for clamping the adjusting belt 7, the width of the inner cavity of the through groove 8 is matched with the width of the adjusting belt 7, and the first rotating claw beam 1 is pressed by the torsional spring structure 3, the adjusting belts 7, the drag hook 6 and the tooth socket 5, make the closed centre gripping of binding clip 4, utilize torsional spring structure 3 to rotate 2 applys pressure of claw-beam to the second simultaneously, make the second rotate 2 one ends of claw-beam closed, utilize 8 to cup joint regulation band 7 simultaneously, increase frictional force through tooth's socket 5, make the second rotate 2 that claw-beam fixes regulation band 7, use binding clip 4 to carry the stomach wall, catch on the tissue with drag hook 6, make through the length of adjustment regulation band 7 and produce pulling force to drag hook 6, thereby utilize the pulling of drag hook 6 to pull the tissue, expose the operation field of vision, realized exposing the function in the abdominal cavity help field of vision, the practicality of this retractor for laparoscopic surgery has been improved.

In conclusion, when the retractor for laparoscopic surgery is used, one end of the first rotary forceps rod 1 is pressed at first to open the forceps head 4, the forceps head 4 is used for clamping the abdominal wall, then the second rotary forceps rod 2 is pressed to open one end of the second rotary forceps rod 2, the adjusting belt 7 penetrates through the inner cavity of the through groove 8, the tissue is hooked by the draw hook 6, the length of the adjusting belt 7 is adjusted to generate a pulling force on the draw hook 6, so that the liver is drawn by pulling the draw hook 6 to expose the surgical field of vision, then the second rotary forceps rod 2 is loosened to clamp the adjusting belt 7 by the second rotary forceps rod 2, and the retractor is used.
