Description

Drag hook that hepatobiliary surgery used

Technical Field

The utility model relates to the technical field of medical instruments.

Background

With the continuous improvement of the living standard at present, the treatment level of some surgical diseases is also continuously improved; liver and gall surgery mainly researches hepatocellular carcinoma, hepatobiliary calculus, posthepatitic cirrhosis and acute liver failure caused by severe hepatitis, and is a major disease seriously threatening the health of Chinese people.

At present, in hepatobiliary surgery, in order to provide a larger surgical field for a doctor to perform surgical operation, a retractor device is needed to pull the skin and flesh on two sides of an opening at a focus of a patient. Chinese patent CN207821859U provides a liver and gall bladder surgery retractor, which comprises a supporting plate, a motor, a screw rod, a bearing seat, a movable rod, a retractor main body, an electric lifting rod, a supporting rod, a gear, a rack and a clamping plate, wherein the motor, the screw rod and the bearing seat are installed at the inner end of the supporting plate; the patent can successfully pull the skin and flesh on two sides of the opening of the focus of the patient, and the operation is simple; however, in the actual operation process, because the positions of the openings of the focus of the patient are slightly different, the angle of the above patent can not be adjusted, which brings great inconvenience to the operation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a draw hook for hepatobiliary surgery to solve the problem that the current draw hook for hepatobiliary surgery can not adjust the angle.

In order to achieve the above object, the basic scheme of the present invention is as follows: a draw hook for hepatobiliary surgery comprises a rack and a draw hook, wherein a disc is arranged on the rack, and a ring groove is arranged on the disc; a circular ring is rotationally connected in the annular groove, and an adjusting mechanism for stopping the circular ring is arranged on the circular ring; the bottom of the circular ring is fixedly connected with a support, and the draw hook is arranged on the support.

The advantages of the basic scheme are: this scheme passes through the adjustment that the support angle was realized in the rotation of ring in the annular, and then realizes the adjustment of drag hook angle, and the rethread adjustment mechanism realizes the location to the ring, compares in present hepatobiliary surgery drag hook, can adjust the drag hook angle to patient's focus department open-ended different positions, and the practicality is stronger.

Further, adjustment mechanism includes that circumference sets up a plurality of screw holes on the ring and the threaded rod with screw hole threaded connection, the screw hole communicates with each other with the annular. Through the arrangement, when the angle of the draw hook needs to be adjusted, the handheld circular ring rotates in the annular groove, and when the draw hook is positioned right above the opening position of the focus of a patient, the circular ring stops rotating; the hand-held threaded rod rotates in the threaded hole, so that the threaded rod is abutted against the groove wall of the annular groove, the positioning of the annular groove is realized, the positioning of the bracket is further realized, and the positioning of the draw hook is realized; and, because threaded connection structure has the auto-lock nature, avoid the threaded rod to take place to remove, and then strengthened the location effect to ring, support and drag hook.

Furthermore, a holding block is arranged on the threaded rod. Through the setting, the handheld holding block is more convenient for force application compared with a handheld threaded rod.

Furthermore, a plurality of positioning holes for the threaded rod to extend into are circumferentially arranged on the annular groove. Through the arrangement, when the draw hook needs to be positioned after the angle adjustment is finished, the threaded rod is rotated and extends into the positioning hole, so that the threaded rod is abutted against the wall of the positioning hole; the positioning effect on the threaded rod can be further enhanced through the positioning hole, and then the positioning effect on the circular ring, the support and the draw hook is enhanced.

Further, the bracket is rotatably connected with a rotating shaft; the rotating shaft is sleeved with a gear, racks meshed with the gear are arranged on the upper side and the lower side of the gear, the racks are connected with the support in a sliding mode, and the draw hook is arranged on the racks; and a stopping mechanism for stopping the rotating shaft. Through the arrangement, the gear rack structure is adopted to simultaneously drive the two drag hooks to pull apart the skin and flesh on the two sides of the opening of the focus of the patient, so that the skin and flesh on the two sides of the opening of the focus of the patient are uniformly stressed; moreover, the skin and flesh on two sides of the opening at the focus of the patient are pulled open manually, so that the skin and flesh can be pulled open slowly, and further the damage to the skin and flesh of the patient is reduced; and the gear rack is positioned through the stop mechanism, so that the position of the draw hook is positioned, and a larger surgical field is provided for the doctor to perform surgical operation.

Furthermore, the stop mechanism comprises a side rod fixedly connected with the rotating shaft and a plurality of stop holes arranged on the bracket, and the side rod is connected with a stop rod extending into the stop holes in a sliding manner. Through the arrangement, the side lever is held by hand to drive the rotating shaft to rotate, the rotating shaft drives the gear to rotate, and the gear drives the upper rack and the lower rack to move in opposite directions or in opposite directions; when the two racks move in opposite directions, the skin and flesh on two sides of the focus opening of the patient are pulled open by the draw hooks on the two racks, and then the stop rod slides to stretch into the stop hole, so that the positioning of the rotating shaft is realized, and the positioning of the gear is further realized, namely the positioning of the draw hooks is realized.

Further, a rubber sleeve is arranged on the side rod. Through the setting, because the rubber sleeve is flexible material, utilize the rubber sleeve to replace the side lever direct and hand contact, handheld rubber sleeve comfort is better.

Furthermore, the rubber sleeve is provided with anti-skid lines. Through the arrangement, the friction force of the anti-slip lines can be increased, and the slipping phenomenon is avoided.

Furthermore, the draw hook comprises a straight section and an arc-shaped section. Through the setting, straight section pastes with patient's skin meat mutually, utilizes the arc section pulling skin meat, and the design is more reasonable, and is higher with patient's skin meat laminating degree for the pulling effect of drag hook to patient's skin meat is better.

Furthermore, a plurality of through holes are formed in the straight section. Through the arrangement, on the one hand, the weight of the draw hook can be reduced, and on the other hand, the production cost can be saved.
