Abstract

A suspensory cold light source shadowless draw hook relates to the medical appliance. It consists of a semiautomatic retractor, a suspending draw hook, a suspending pull wire, a wire locking unit, a suspending bracket and a locking block. The head of the semiautomatic retractor is inserted into the fixed groove block 13 of the draw hook, the two petioles are held to open the two suspending draw hooks, and the unidirectional gear brake makes them not retracted. The suspending draw hook includes a power plug, a mini-type high-luminance cold light component, draw hook bodies, a draw hook neck and draw hook petioles. One end of the suspending pull wire is connected to the petioles of the suspending draw hook, and the other end is inserted into the wire locking unit whose spring and pressing beads inside make the pull wire not retract after tightly pulled. The suspending bracket is inserted into the hole of the locking block, which is fixed in the runway on the side of the operating table, and then the fastening screw of the locking block is fastened. Put the two draw hook bodies into the abdominal cavity through the incision, and tightly pull the suspending pull wire, the suspending draw hook would then lift the abdominal wall upward, and the suspending bracket can be adjusted up and down to a required height. The utility model is useful for non-pneumoperitoneum celioscope operations and small incision operations.

Description

Suspension does not have shadow cold light source drag hook

Technical field

This utility model is that suspension does not have shadow cold light source drag hook, belongs to medical apparatus and instruments, is specially adapted to the single hole gasless laparoscopic operation.

Background technology

Present laparoscopic surgery is to open four holes away from field of operation, CO ₂Gas injects the abdominal cavity and causes the working place, needs pneumoperitoneum apparatus equipment.Exist following deficiency: 1. CO ₂The pneumoperitoneum complication is as the harmful effect to cardiovascular and cerebrovascular vessel of: pulmonary insufficiency, subcutaneous emphysema, pneumothorax, pneumopericardium, gas embolism, thrombosis, hypercapnia, acidosis; 2. operation can not be line-of-sighted observation the easy generation collimation error, causes tissue injury, and the severe complication incidence rate is much larger than traditional abdominal.3. ligation is sewed up difficulty and is adopted metal clip, has that metal clip comes off, a metallic foreign body, the deficiency that should not frequently use, and ligation is sewed up many operations and is difficult to carry out; 4. equipment complex and expensive (about 600,000 yuan), technology are difficult to be grasped, and applies difficulty.Peritoneoscope also needs to join in addition fiber cold light source device illumination at present in addition, and single luminous point direct-view is difficult to accomplish shadowless lighting.

Summary of the invention

The purpose of this utility model is to overcome the CO that peritoneoscope exists in the prior art ₂Pneumoperitoneum complication, equipment complex and expensive, traditional abdominal damage weak points such as big, provide a kind of otch little, have to amplify to observe picture, and the suspension that has miniature and high brightness cold light light-emitting component does not have shadow cold light source drag hook.

The purpose of this utility model is achieved through the following technical solutions.

A kind of suspension does not have shadow cold light source drag hook, is made up of semi-automatic dilator, suspensory retractor, suspention wire drawing, wire locking device, pipe-hanging hook, latch segment.Two heads of described semi-automatic dilator insert in the groove of described suspensory retractor cervical region, the stringy end of described suspention is plugged in the groove of suspensory retractor shank, suspend the stringy other end in midair and pass centre bore and the tension that is positioned over the wire locking device on the pipe-hanging hook, pipe-hanging hook inserts in the locking block hole that is installed on the operation bedside runway, and the holding screw of latch segment is pipe-hanging hook fixedly.

Described semi-automatic dilator comprises two heads, two shanks, central shaft and unidirectional tooth valve.

Described suspensory retractor comprises drag hook body, drag hook neck and drag hook handle, is provided with attaching plug in the drag hook handle, is provided with a plurality of miniature high brightness cold light elements in the drag hook body, and the drag hook neck is provided with the groove that cooperates semi-automatic dilator head to insert.

Described wire locking device comprises spring, presses pearl, shell, loose ends button, and described suspention wire drawing is inserted in the hole of this wire locking device.

Suspensory retractor of the present utility model is inserted the abdominal cavity through single hole, strut, cooperate down through suspention wire drawing, wire locking device, pipe-hanging hook, latch segment again stomach wall is suspended in midair, make field of operation that good exposure and working place be arranged, and shadowless lighting arranged, can utilize new technique single hole mirror to observe the operation down that combines in direct-view and amplification picture, can utilize new technique " deep electric knotter " ligation to sew up, non-pneumoperitoneum condition is finished abdominal operation.

This utility model compared with prior art has following advantage:

(1) no CO ₂Pneumoperitoneum is to lung, the heart, cerebrovascular harmful effect;

(2) both suspended stomach wall in midair and produced the excellent operation space, the no shadow cold light source of band guarantees illumination again.

(3) being adapted at direct-view and monitor to amplify picture and observe to combine down and finish operation, is the advantage combination of laparoscopic technique and traditional abdominal, makes more convenient operation accurate, and technology is easily grasped.

(4) can make otch near field of operation, " deep electric knotter " ligation of being convenient to use of the new technology is sewed up, and can remove the disadvantage of using metal clip from.

(5) simplified equipment, cost reduces greatly.
