Description

Blood vessel separating and cutting device for laparoscope

Technical Field

The utility model relates to a peritoneoscope application technology field specifically is a peritoneoscope is with blood vessel from disconnected ware.

Background

The development of modern medicine, minimally invasive surgery has been the development direction of surgical operation at present, and minimally invasive surgery has the advantages of small wound, quick recovery and less pain, and has become the object and the direction which are jointly pursued by modern medicine. In some aspects, the laparoscopic technology gradually replaces the traditional operation, and in laparoscopic operation, when an electrotome, an ultrasonic scalpel and an energy platform are applied to perform blood vessel separation, although bleeding is not easy to occur, due to the burning effect of electrocoagulation, after the blood vessel is separated by electrocoagulation, the type of the blood vessel cannot be judged by a broken end, and particularly when a bile duct, a lymphatic vessel and the blood vessel need to be distinguished, the laparoscopic technology is more inconvenient. Meanwhile, the blood vessel which is electrocoagulated is more and thicker, or the blood vessel which needs to be cut off is thicker, and exceeds the capability range of the electrotome, the ultrasonic scalpel and even the energy platform to cut off the blood vessel, so that the blood coagulation and the hemostasis effect are satisfactory at that time, but the blood vessel which is originally coagulated bleeds again due to the rise of the blood pressure of a patient or other reasons, and unnecessary mental stress is brought to the patient and a surgeon occasionally. When the blood vessel is cut off by using the tissue clamp, the prior art is troublesome, namely the tissue clamp needs to be used for clamping two naked blood vessel ends twice respectively, then scissors are applied to clamp the two ends by the tissue, and the blood vessel after clamping is cut off, and the process of cutting off the blood vessel needs to repeatedly pass in and out the puncture cannula for at least three times by using surgical instruments, thereby wasting valuable operation time. Bringing inconvenience to the doctor.

The utility model discloses specific use, operating method do: the blood vessel separating device for the laparoscope can be used under the laparoscope, does not need to replace surgical instruments when encountering thick blood vessels, is direct and safe, and can be used for rapidly separating and breaking blood vessel tissues. The condition that delayed bleeding occurs to endanger the life safety of patients when the electric knife, the ultrasonic knife and the energy platform are disconnected from the blood vessel, the disconnection end is closed and cut off, the defect that the structure of the blood vessel cannot be judged is overcome, or the thick blood vessel is disconnected. The specific using and operating method of the instrument comprises the following steps: in the process of laparoscopic surgery, when a blood vessel tubular structure needing to be cut off is met, firstly, the blood vessel is naked, the naked blood vessel pipeline structure is completely exposed, the device is applied, the device is placed into an abdominal cavity through an established puncture tube channel, namely an abdominal wall puncture cannula, in the process of placing the puncture cannula, the movable handle 7 is slightly pulled back, the distance between the left tissue clamping and closing device 1 and the right tissue clamping and closing device 2 is slightly reduced to be mainly placed into the puncture cannula, but in the reducing process, the two tissues are placed into the puncture cannula under the condition that two tissues cannot be completely clamped, then the blood vessel pipeline needing to be cut off is placed between the left tissue clamping and closing device 1 and the right tissue clamping and closing device 2, namely two tissue clamps 3 which are not completely clamped, because the tail ends of the tissue clamps 3 are far away from the front ends of the central scissors 4 of the clamping and the surrounding tissues cannot be contacted, therefore, the scissors 4 in the center of the clipping device can not cause tissue damage, under the condition that the tissue clip 3 can completely clip the blood vessel, the movable handle 7 is pulled backwards, under the action of the connecting rod 5, the tissue clipping device 1 on the left side and the tissue clipping device 2 on the right side can close the tissue clip 3 with anti-skid teeth and buckles, at the moment, the two tissue clips 3 can clip the blood vessel on the two sides of the scissors 4 in the center of the clipping device, after observing the blood vessel clipping satisfaction of the tissue clip 3 again, the instrument is pushed forwards, the head end of the instrument is slightly moved leftwards or rightwards, the front end arc arms, namely the tissue clip fixing clamping grooves 11, of the tissue clip 1 on the left side and the tissue clipping device 2 on the right side are staggered, so as to avoid bouncing the clipped tissue clip 3 off or causing other influences, and simultaneously the tissue clipping device 1 on the left side and the tissue clipping device on the right side are in an arc structure bending towards the two sides, when the instrument is moved forwards, the front tissue can be pushed away, the central scissors 4 of the clamping and closing device are applied, when a blood vessel is cut between two tissue clamps 3, at the moment, the tissue clamp fixing clamping groove 11 cannot touch the clamped tissue clamp 3, the tissue in the operation area and the clamped tissue clamp 3 cannot be damaged, the cut tissue broken end can be conveniently observed in the process of cutting the tissue between the two tissue clamps 3, the tissue source can be further judged, after the whole cut tissue is cut off, the movable handle 7 is pulled back, the left tissue clamping and closing device 1 and the right tissue clamping and closing device 2 are closed together, the abdominal cavity puncture sleeve is taken out, the cut tissue operation is completed, in the single cut tissue process, the operation instrument does not need to be repeatedly replaced, the operation of clamping and cutting the tissue can be completed once by using the instrument, and the precious operation time can be greatly saved. If the blood vessel structure is unclear and puzzled to be cut off, a small part of the blood vessel to be cut off can be placed into the central scissors 4 of the clamping device, the central scissors 4 of the clamping device can cut off the small part of the tissue, the tissue type can be judged according to the color of liquid flowing out of the broken end of the tissue and the structure of the broken end, and the defects that when the blood vessel is cut off by an electrotome, an ultrasonic knife and an energy platform, the blood vessel is completely coagulated and the tissue source cannot be judged are overcome. Through clinical practice, the instrument is convenient, rapid and flexible to operate, and the operation safety is effectively improved. The instrument may be plasma sterilized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
