Abstract

The invention discloses an abdomen opening device, which comprises two abdomen opening arms one ends of which are hinged together, and the other ends are respectively provided with an abdomen opening plate, the hinged end of the two abdomen opening arms is provided with a locking device, at least one abdomen opening arm is in sliding connection with a pull rod, the abdomen opening arm is also provided with a pull rod locking device, and the end close to the abdomen opening plate on the pull rod is provided with a viscus dragging plate; and the viscus dragging plate is connected on the pull rod via a direction regulating mechanism. When abdominal surgery is carried out, the abdomen opening device can make the operative field exposed sufficiently, the viscera dragging plate at the pull rod stretch-in end is used for poking other viscera to replace the manual operation of medical workers, which is conductive to controlling the force and the angle when dragging the viscera, and greatly reduces the working intensity of the medical workers, so the invention has the advantages of ensuring the angle and the force for dragging the viscera and ensuring the exposure of the operative field.

Description

A kind of abdomen opening device

Technical field

The invention belongs to abdominal operation and use instrument field, specifically is a kind of abdomen opening device that is used to strut the abdominal cavity.

Background technology

When doing abdominal operation, need do otch from stomach wall, abdomen opening device is stretched into from incision strut stomach wall, make the wild exposure of art.Existing abdomen opening device comprises two abdomen arms that an end is hinged, and a web respectively is equipped with in the bottom of two abdomen arms, opens an abdomen arm during use and makes two abdomen arms form certain angle, opens web and props up stomach wall, and art is wild to be exposed thereby make.The shortcoming that this abdomen opening device exists is: abdominal visceral browser is many; When undergoing surgery to a certain internal organs, need the multidigit medical personnel with medical appliance from other internal organs of all directions tractive, medical personnel are difficult to guarantee the angle and the dynamics of tractive internal organs when undergoing surgery; Thereby be prone to cause the wild instability that exposes of art; Strengthen medical personnel's labor intensity, also be prone to prolong operating time, be unfavorable for rehabilitation of patients.

Summary of the invention

The technical problem that the present invention will solve provides the angle and the dynamics that can guarantee the tractive internal organs and can guarantee the wild a kind of abdomen opening device that exposes of art.

For solving the problems of the technologies described above; The abdomen opening device of following structure is provided: this abdomen opening device comprises that two that an end is hinged, a web respectively is equipped with in the other end are opened the abdomen arm; The hinged end of two abdomen arms is provided with locking device; Slidely connect pull bar at least one the abdomen arm, this abdomen arm also is provided with the pull bar locking device, near an end of opening web the visceral pulling plate is housed on the pull bar; Its construction features is: said visceral pulling plate direction of passage governor motion is connected on the pull bar; Described direction adjustment organization comprises the bearing that is hinged on tie rod end through first jointed shaft, is bolted with first locking nut on first jointed shaft, and described visceral pulling plate is installed on the bearing.

After adopting said structure, when doing abdominal operation, this abdomen opening device is stretched into from incision; Opening two abdomen arms makes two abdomen arms form certain angle also through its opening angle of locking device locking; The web of opening that is arranged on an abdomen arm end props up stomach wall and struts stomach wall, and the inner extending end of pull bar is stretched into intraperitoneal, catches on internal organs through the visceral pulling plate after arriving assigned address; Again pull bar is pulled back and pass through the pull bar locking device and lock pull bar; Thereby push other internal organs aside the internal organs that need undergo surgery are exposed, use this abdomen opening device can make the wild exposure of art fully, stir other internal organs with the visceral pulling plate of pull bar inserting end and replace medical personnel's manual operations; Dynamics when helping controlling the tractive internal organs and angle, and greatly reduce medical personnel's working strength.Therefore the present invention has the angle and the dynamics that can guarantee the tractive internal organs and can guarantee the wild advantage that exposes of art.What the direction of passage governor motion can be adjusted the visceral pulling plate stretches into direction and direction of draw, so that the visceral pulling plate better catches on and the tractive internal organs.

Respectively be connected with a pull bar on two abdomen arms.

As the improvement of above-mentioned direction adjustment organization, be hinged with Connection Block through second jointed shaft on the bearing, be bolted with second locking nut on second jointed shaft, described visceral pulling plate is installed on the bearing through Connection Block.First jointed shaft is perpendicular to the plane at two abdomen arm places, and second jointed shaft is parallel to the plane at two abdomen arm places.

As further improvement of the present invention, the visceral pulling plate is provided with the slotted hole that is provided with along its length direction, is bolted with the set bolt that passes slotted hole on the Connection Block.

Part away from slotted hole on the said visceral pulling plate roughly is arcuation.

Open the abdomen arm and be provided with sliding tray, pull bar is installed in the sliding tray, and said pull bar locking device comprises the bolt that passes sliding tray and is screwed onto the lock nut on the bolt.

Wherein offer arcuate groove on an abdomen arm, said locking device comprises the bolt that passes two abdomen arms and arcuate groove and is screwed onto the nut on the bolt.
